The appropriate surgical procedure for patients with upper third early gastric cancer is controversial. We compared total gastrectomy (TG) with proximal gastrectomy (PG) in this patient population. A multicenter, non-randomized trial was conducted, with patients treated with PG or TG. We compared short- and long-term outcomes between these procedures. Between 2009 and 2014, we enrolled 254 patients from 22 institutions; data from 252 were included in the analysis. These 252 patients were assigned to either the PG (n = 159) or TG (n = 93) group. Percentage of body weight loss (%BWL) at 1 year after surgery, i.e., the primary endpoint, in the PG group was significantly less than that of the TG group (− 12.8% versus − 16.9%; p = 0.0001). For short-term outcomes, operation time was significantly shorter for PG than TG (252 min versus 303 min; p

The patient was a 60-year-old man who underwent distal gastrectomy for gastric cancer. The pathological diagnosis was Stage ⅡB. He received adjuvant chemotherapy(capecitabine plus oxaliplatin: CapeOX)for 6months and the postoperative course was uneventful. One year and 3 months after surgery, he visited the outpatient department for acute lower back pain. Blood tests showed elevated ALP(3,752 U/L), LDH(308 U/L), and CA19-9(69.4 U/mL)levels. Bone scintigraphy showed multiple bone metastases to the femora, ischium, iliac bone, vertebrae, sternum, costae, and scapulae in a super bone scan. The onset of disseminated intravascular coagulation(DIC)was observed later. The patient was diagnosed with disseminated carcinomatosis of the bone marrow. Radiation therapy was performed and anti-RANKL monoclonal antibody was administered for the bone metastases. Recombinant human soluble thrombomodulin was administered for DIC. He received chemotherapy( TS-1 plus cisplatin: SP)but died 4 months after the diagnosis. The prognosis of disseminated carcinomatosis of the bone marrow is extremely poor. We report this case along with a literature review.

Introduction Repair of supra-pubic incisional hernia is still challenging because of the highest pressure at the lower abdominal wall in the erect position. Recently, laparoscopic preperitoneal mesh repair has been gradually reported. Case presentation A 77-year-old woman underwent single-incision laparoscopic preperitoneal mesh repair under a diagnosis of a supra-pubic incisional hernia, measuring 7 × 4 cm. A single, 2.5-cm, intraumbilical incision was made, followed by creation of the preperitoneal space. Then, the posterior rectus sheath and peritoneum were opened, and laparoscopic exploration was performed. After dissection of the supra-pubic hernia content, the tube for degassing the abdominal cavity was inserted into the abdominal cavity, and the peritoneum and the posterior sheath were closed. The preperitoneal space was dissected gradually, and circular dissection of the hernia sac was performed. The proximal sac (peritoneum) was sutured continuously. A 15 × 10 cm mesh was placed in the preperitoneal space and fixed securely with absorbable tacks at the pubic bone, Cooper's ligament, and the rectus abdominis muscle, respectively. After degassing the preperitoneal space, a second laparoscopic exploration was performed to confirm the secure suture of the peritoneum and no injury of the abdominal organs. At 4-month follow-up, the patient remained well with no signs of recurrence. Discussion Single-incision laparoscopic preperitoneal mesh repair could minimize the recurrence of supra-umbilical incisional hernia and perioperative complications. Conclusion Single-incision laparoscopic preperitoneal mesh repair, offering good cosmetic results, might be useful for repair of supra-pubic incisional hernia.

INTRODUCTION The learning curve for totally extraperitoneal repair (TEP) is longer and steeper than that for transabdominal preperitoneal repair (TAPP) due to the preperitoneal view to which the surgeon is not accustomed and the limited working space. The aim of this study was to clarify the learning curve for SILS-TEP. METHODS A retrospective analysis of 80 consecutive patients with unilateral inguinal hernia was performed. All patients underwent elective SILS-TEP performed by a single learning surgeon with a teaching assistant between July 2016 and March 2018 at Kinki Central Hospital. RESULTS The operative time decreased gradually after 20 cases and stabilized after 40 cases. The first 40 cases were categorized as the learning period group, and the remaining 40 cases were categorized as the experienced period group. More patients received antithrombotic therapy in the experienced period than in the learning period (P

Introduction The aim of this study was to evaluate the efficacy of single-incision laparoscopic surgery for totally extraperitoneal repair (SILS-TEP) of irreducible inguinal hernias and incarcerated inguinal hernias. Methods We performed a retrospective analysis of 194 patients, including 16 with irreducible or incarcerated hernia, who had undergone SILS-TEP from May 2016 to December 2017 at Kinki Central Hospital. The outcomes of patients with irreducible or incarcerated hernia and those with reducible hernia were compared. For irreducible or incarcerated hernia, laparoscopic exploration with hernia reduction through an intraumbilical incision was performed. If no bowel resection was needed, one-stage SILS-TEP was performed. If bowel resection was required, two-stage SILS-TEP was performed 2-3 months after the bowel resection. Results Of the 16 patients, 8 had an irreducible hernia, and 8 had an incarcerated hernia. The eight patients with an incarcerated hernia underwent emergency surgery, and among these patients, two needed single-incision laparoscopic partial resection of the ileum followed by two-stage SILS-TEP. Fourteen patients, excluding the two patients who required single-incision laparoscopic partial resection of the ileum, underwent laparoscopic exploration with hernia reduction followed by one-stage SILS-TEP. Among these 14 patients, one with an irreducible hernia required conversion to Kugel patch repair. The operative outcomes were generally comparable between the two groups. However, the operative time was longer for unilateral hernia, and more seromas were seen in the irreducible or incarcerated group. No other major complications or cases of hernia recurrence were noted in this study. Conclusions SILS-TEP, which offers good cosmetic results, can be safely performed for irreducible or incarcerated inguinal hernia.

Highlights • Primary splenic malignant lymphoma should be included among the differential diagnoses of splenic tumors. • Curative resection might be a therapeutic option for the treatment of primary splenic malignant lymphoma. • Laparoscopy-assisted splenectomy is useful for reducing the length of incisions and the operative invasiveness., Introduction Primary splenic malignant lymphoma is quite a rare disease, and its preoperative diagnosis is difficult. Case presentation An 80-year-old man was diagnosed with advanced rectosigmoid cancer with liver and splenic metastases, for which he underwent single-incision laparoscopic high anterior resection for the primary rectosigmoid cancer. After chemotherapy, he underwent laparoscopy-assisted splenectomy and open partial hepatectomy of segment 3 and segment 5/6 of the liver. The resected specimen of the spleen showed primary splenic malignant lymphoma. Discussion A diagnosis of primary splenic malignant lymphoma seems to be made only occasionally at splenectomy. Patients with primary splenic malignant lymphoma treated by curative resection at an early clinical stage have a more favorable prognosis. Laparoscopy-assisted splenectomy is useful for reducing surgical invasiveness. Conclusion Primary splenic malignant lymphoma should be included among the differential diagnoses of splenic tumors in patients with colorectal cancer with multiple metastases. Curative resection might be a therapeutic option for the treatment of primary splenic malignant lymphoma. Laparoscopy-assisted splenectomy is a useful strategy for reducing surgical invasiveness.

Highlights • Medullary carcinoma should be distinguished from other more aggressive, non-glandular tumors of the colon, because medullary carcinoma appears to have a better survival outcome than undifferentiated colon adenocarcinoma. • Omental infarction should be considered in the differential diagnosis of acute abdomen after surgery., Introduction Medullary carcinoma is a rare type of colorectal adenocarcinoma, and omental infarction is a rare cause of acute abdomen. Presentation of case A 72-year-old woman underwent single-incision laparoscopic right hemicolectomy for ascending colon cancer. Pathological examination showed a medullary carcinoma (MC) of T4aN0M0 Stage IIB. Her postoperative course was uneventful, and she was discharged on postoperative day (POD) 6. From POD 7, she suffered from fever, and she returned to the hospital on POD 9. Plain computed tomography showed free air beside the anastomotic site around the elevated density of fat tissue and gallbladder wall thickening with a gallstone. Suspecting anastomotic leakage with acute cholecystitis, probe laparotomy was performed. Intraoperative observation confirmed omental infarction with acute cholecystitis, and no leakage was found at the anastomotic site. Therefore, the necrotic part of the greater omentum was resected, and cholecystectomy was performed. She has remained well, with no evidence of recurrent cancer during the 12 months of follow-up without chemotherapy after the surgery for MC of the ascending colon. Discussion MC should be distinguished from other more aggressive, non-glandular tumors of the colon because MC appears to have a better survival outcome than undifferentiated colon adenocarcinoma. Omental infarction should be considered in the differential diagnosis of acute abdomen after surgery. Conclusion A rare case of medullary carcinoma of the ascending colon followed by infarction of the greater omentum mimicking anastomotic leakage is presented.

The examination of hematoxylin and eosin (H&E)-stained tissues on glass slides by conventional light microscopy is the foundation for histopathological diagnosis. However, this conventional method has some limitations in x-y axes due to its relatively narrow range of observation area and in z-axis due to its two-dimensionality. In this study, we applied a CUBIC pipeline, which is the most powerful tissue-clearing and three-dimensional (3D)-imaging technique, to clinical pathology. CUBIC was applicable to 3D imaging of both normal and abnormal patient-derived, human lung and lymph node tissues. Notably, the combination of deparaffinization and CUBIC enabled 3D imaging of specimens derived from paraffin-embedded tissue blocks, allowing quantitative evaluation of nuclear and structural atypia of an archival malignant lymphoma tissue. Furthermore, to examine whether CUBIC can be applied to practical use in pathological diagnosis, we performed a histopathological screening of a lymph node metastasis based on CUBIC, which successfully improved the sensitivity in detecting minor metastatic carcinoma nodules in lymph nodes. Collectively, our results indicate that CUBIC significantly contributes to retrospective and prospective clinicopathological diagnosis, which might lead to the establishment of a novel field of medical science based on 3D histopathology.

Malignant stricture and fistula of the esophagus and tracheobronchus adversely affect the quality of life(QOL)in patients with advanced esophageal cancer. Stenting is one ofthe therapies available for these patients. We investigated the outcomes ofesophagus and tracheobronchial stenting in our institution. Eight patients with advanced esophageal cancer underwent double stenting from 2010 to 2016. Among them, 4 patients underwent double stenting as planned. One patient underwent an emergency tracheal stenting because ofstenosis ofthe trachea caused by esophageal stenting. Three patients underwent tracheobronchial stenting later on because ofan increase in the tumor size after esophageal stenting. Dysphagia score was improved in 5(67.5%)out ofthe 8 patients. Respiratory symptoms were improved in all patients, and 4 patients(50.0%) were discharged. The median survival time after esophageal stenting was 70.5 days. Esophagus and tracheobronchial stenting for advanced esophageal cancer was useful for the improvement of the QOL.

Chemotherapy is performed for the recurrence of gastric cancer in many cases. We report a case of recurrent lymph node metastasis successfully treated with chemoradiotherapy and chemotherapy. A man in his 60s underwent total gastrectomy and D2 dissection in 2009. The pathological diagnosis was poorly differentiated adenocarcinoma, T4a, int, INF b, ly2, v2, LN#2: 2/3, #3: 1/4, #7, 8, and 9: 3/4, stage III B. Although we administered S-1/UFT as postoperative adjuvant chemotherapy, a strong rash appeared and the patient ceased chemotherapy. Eight months later, the rash had disappeared. We started chemotherapy with paclitaxel(PAC). CT performed 1 year postoperatively showed celiac lymph node(#9)metastasis. Chemoradiotherapy( RT+PAC)and additional CPT-11(98mg)and CDDP(49mg)treatment were administered. The lymph node (#9)was cicatrized after 8 cycles. Forty-two months after the end of treatment, the patient has had no recurrence. It is thought that chemoradiotherapy is an effective cure for local recurrence of gastric cancer.

Background and Objectives Gastroduodenal stents for gastric outlet obstruction due to unresectable advanced gastric cancer are increasingly used; however, their effects have not been fully evaluated. Methods A multicenter prospective observational study was performed. Patients were eligible if they had stage IV gastric cancer with a gastric outlet obstruction scoring system (GOOSS) score of 0 (no oral intake) or 1 (liquids only). Self-expandable metallic stents were delivered endoscopically. The effects of stents were evaluated. Results Twenty patients were enrolled and 18 were eligible (15 men, three women; median age, 70 years). Stent placement was successfully performed in all patients, with no complications. After stenting, a GOOSS score of 2 (soft solids only) or 3 (low-residue or full diet) was achieved in 13 (72%) patients. An improvement in the GOOSS score by one or more points was obtained in 16 (94%) patients. The median duration of fasting and hospital stay was 3 (range, 0–9) days and 18 (6–168) days, respectively. Chemotherapy was performed after stenting in 13 (72%) patients. Conclusions Gastroduodenal stents are thought to be feasible, safe, and effective for gastric outlet obstruction due to unresectable advanced gastric cancer, with rapid clinical relief and a short hospital stay.

Introduction To confirm the safety and feasibility of single-incision laparoscopically assisted appendectomy (SILA) performed by resident doctors. Materials and methods We retrospectively analyzed 86 consecutive patients who underwent SILA between August 2010 and August 2016 at Kinki Central Hospital. During this period, 9 residents and 6 board-certified attending surgeons performed SILA. Data on the patients' characteristics and perioperative complications were collected from their medical records. Results Resident doctors operated on 55% (47/86) of patients undergoing SILA. There were no significant differences between the groups with regard to patient characteristics. Mean operative time in the resident and staff surgeon groups was 74 min and 71 min, respectively (p = 0.5). Median blood loss in both the resident and staff surgeon groups was 0 mL (p = 0.3). The rate of conversion to a different operative procedure was 4% (2/47) in the resident group and 3% (1/39) in the staff surgeon group (p = 1). All three above-mentioned procedures, two (4%, 2/47) in the resident group and one (3%, 1/39) in the staff surgeon group, were converted to multi-port laparoscopic appendectomy. The mean postoperative hospital stay was 5 days for both the resident and staff surgeon groups (p = 0.7). Perioperative complications developed in 9% (4/47) of the patients in the resident group and 21% (8/39) of the patients in the staff surgeon group (p = 0.1). Conclusions SILA performed by residents under the guidance of a staff surgeon is safe and feasible., Highlights • Single-incision laparoscopically assisted appendectomy could be performed with acceptable morbidity by the residents. • Single-incision laparoscopically assisted appendectomy performed by residents under the guidance of a staff surgeon is safe and feasible.

Reliable indicators that can intraoperatively determine the absence of nodal metastasis are in great demand to avoid unnecessary lymphadenectomy. However, little has been reported about the intraoperative diagnostic performance of sentinel node (SN) biopsy. Sentinel node biopsy by subserosal or submucosal injection of indocyanine green (ICG) was performed in 241 patients with American Joint Committee on Cancer tumor, node, metastasis staging system, 7th edition, clinical T1 (n = 190) and T2 (n = 51) gastric cancer by two experienced surgeons. All nodes that stained green (green node, GN), representing SNs, were excised before gastrectomy and were sliced into 2-mm sections for intraoperative histological examinations with hematoxylin and eosin staining. The sliced GNs were also examined simultaneously by imprint cytology. The GNs were detectable in 240 patients (3.8 ± 2.4 nodes per patient; range 1–17 nodes; median 3 nodes), and the success rate of detection was 99.6 % (240 of 241). Of 240 patients with a successful detection, 29 were found to have lymph node (LN) metastases; 16 were diagnosed with LN metastases in both GNs and non-GNs, 12 in GNs alone, and 1 in non-GNs alone. The false-negative rate based on the SN concept was 3.4 % (1 of 29). However, two patients with cT1 gastric cancer were diagnosed as intraoperative GN negative but were later confirmed as GN positive by histological examinations of paraffin sections. As an intraoperative diagnosis, the false-negative rate was 10.3 % (3 of 29). Sentinel node biopsy using ICG could be performed intraoperatively within reasonable limits under certain conditions, such as multiplanes for detection, combination use of imprint cytology, and open surgery by experienced surgeons.

When a suture does not trap a sufficient volume of pancreatic parenchyma in the conventional pancreatic anastomosis, laceration may be caused by even modest tension. Therefore, we used mattress sutures with gastric wall, which works protectively. An opening was made on the posterior wall of the stomach. By using a 3-0 polypropylene monofilament thread with a straightened needle at each end, the proximal gastric wall, the pancreas, and the distal gastric wall were sutured sequentially to accomplish anastomosis in a U-like fashion. After 2 to 4 additional sutures were completed, the pancreatic stump was invaginated into the stomach and all sutures are tied. Mattress sutures were made on the pancreas, which was held between the superior and inferior walls of the stomach. Postoperative amylase levels in the drainage fluid decreased significantly and none of the 17 patients developed pancreatic fistula formation. The technique is simple and shortens the time required for anastomosis.

Neoadjuvant chemotherapy may improve survival of responders in esophageal cancer patients but is useless and harmful in non-responders. Thus, it is important to predict the effect of the chemotherapy, and that any predictor must be applicable clinically. The aim of this study is to examine the correlation between pretherapeutic hypercoagulopathy as determined by plasma d-dimer levels and response to chemotherapy. In 71 patients with esophageal cancer who underwent neoadjuvant chemotherapy (cisplatin, adriamycin and 5-fluorouracil) followed by surgery, plasma d-dimer levels were measured before chemotherapy and the clinical and pathological responses to chemotherapy were assessed at 4 weeks after therapy (after surgery). Pretherapeutic plasma d-dimer level was significantly lower in clinical responders (complete response/partial response [CR/PR]; 0.62 +/- 1.10 microg/mL, mean +/- SD) than in non-responders (no change/progressive disease [NC/PD]; 1.15 +/- 1.08 microg/mL, P = 0.0491), and in pathological responders (Grade 1b-3; 0.62 +/- 1.11 microg/mL) and non-responders (Grade 0-1a; 1.15 +/- 1.05 microg/mL, P = 0.0107). The optimal cut-off level of the plasma d-dimer levels for predicting clinical and pathological responses was 0.6 microg/mL. Then, sensitivity and specificity for the prediction of CR/PR were 68% and 73%, and those for Grade 1b-3 were 91% and 69%, respectively. Our results suggested that pretherapeutic plasma d-dimer level correlated significantly with clinical and pathological responses to chemotherapy. Pretherapeutic plasma d-dimer level can be used as a predictor for chemosensitivity.

An 80-year-old woman was treated with low anterior resection and D3 lymph node dissection for rectal carcinoid in August 2007. Pathological diagnosis was a tumor 23 × 22 mm in size with muscularis propria invasion, ly1, v0, n1 (No. 251[1/12]). Partial hepatectomy was performed for liver metastasis in March 2010 and September 2011. In June 2013, an isolated tumor of 17 mm in diameter was detected between the inferior vena cava and the stomach using abdominal ultrasonography. The tumor was diagnosed as pancreatic head lymph node metastasis using abdominal enhanced computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET); fluorodeoxyglucose (FDG) uptake was noted at the site of the tumor, but not at other parts of the body. Curative resection was the chosen treatment option. Open surgery was performed in September 2013, and a tumor 30 mm in diameter located at the ventral side of the inferior vena cava, lateral side of the portal vein, and cranial side of duodenum was resected. No surrounding tissue infiltration was found. Pathological analysis of the resected specimen indicated lymph node metastasis of the rectal carcinoid. The patient has been disease free for 9 months after surgery.

Background and Objectives Although salvage surgery after definitive chemoradiotherapy (CRT) is common, the safety and indication has not yet been established. Methods We retrospectively compared the mortality and morbidity of 24 patients who underwent salvage surgery with those of historical controls treated with neoadjuvant CRT followed by planned esophagectomy during the same period, and analyzed the prognostic factor of salvage surgery. Results Preoperative serum albumin (3.7 vs. 4.1 g/dl, P = 0.0157) and lymphocyte count (763 vs. 964/mm3, P = 0.0111) in the salvage group were significantly lower than those in the neoadjuvant group. A significant difference was also observed in operation time (567 vs. 474 min, P = 0.0381), C-reactive protein (CRP) on postoperative day 1 (11.2 vs. 8.7 mg/dl, P = 0.0021), and postoperative systemic inflammatory response syndrome (SIRS) duration (3.5 vs. 2.9 days, P = 0.0486). There were three hospital deaths in the salvage group, whereas no patient died in the neoadjuvant group. Multivariate analysis showed curability (R0 vs. R1 + R2) to be the strongest prognostic factor of salvage surgery (P = 0.0064). R1 + R2 operation was more frequently performed in the salvage group (33% vs. 13%), and the reason for all cases was unresectable T4, which had been underestimated preoperatively. Conclusions Salvage surgery is a highly invasive and morbid operation, which is performed on immunocompromized hosts. The indication must be carefully considered, with care taken to avoid non-curative surgery. J. Surg. Oncol. 2006;93:422–428. © 2006 Wiley-Liss, Inc.

The outcome after resection of advanced pancreatic cancers is extremely poor because of the high incidence of the postoperative development of liver metastasis and local recurrence. We performed a combination of chemoradiation and liver perfusion chemotherapy and extended pancreatectomy. Nineteen patients with T3 pancreatic head cancers were enrolled. A total of 24 Gy in 12 fractions of 10-MV x-rays with a concurrent intravenous infusion of 5-fluorouracil (5-FU; 3 g/12 days) was administered to the pancreatic head area. An extended pancreaticoduodenectomy was performed, and catheters were placed into the gastroduodenal artery and the superior mesenteric vein. During the first 28 postoperative days, 5-FU was continuously infused via the hepatic artery and portal vein (3.5 g/28 days × 2). Finally, 36 Gy in 18 fractions with 5-FU (3 g/6 days) was applied to the pancreatic bed. After preoperative chemoradiation, four patients did not undergo surgical resection because of distant metastases. Fifteen patients underwent pancreaticoduodenectomy, liver perfusion chemotherapy, and postoperative chemoradiation. No patient developed grade 3 toxicity as a result of preoperative chemoradiation, but one patient (7%) developed grade 3 leukopenia during the postoperative treatments. The morbidity rate was 20% (3 of 15 patients), and the mortality rate was 0%. The overall 3-year survival rate was 53%. The 3-year disease-free survival rate was 66% in patients who pathologically responded well (>50%), versus 0% in patients with poor responses (P = .04). A combination of preoperative and postoperative chemoradiation plus postoperative liver perfusion chemotherapy with an extended pancreatectomy is feasible, and the long-term outcomes are also promising.

症例は57歳の男性で, 進行食道癌Lt, T3N1M1 lym (#13#16) にて胸部食道全摘, 後縦隔胃管再建, 2領域+16番リンパ節郭清術を施行した. 術後経口摂取開始と共に混濁胸水を認め乳糜胸と診断. 絶食中心静脈栄養 (術後18-58日), 胸管結紮術 (35日), minomycinおよびOK432注入による胸膜癒着 (38-49日), 胸腔左鎖骨下静脈および胸腔腹腔シャント造設術 (64日) と治療行うも1,000-3,000ml/日程度の胸水が持続した. 2回のリンパ管シンチグラフィーではリンパ漏出部位同定は困難であった. 術後121日にリンパ漏出部位同定目的でリピオドールによるリンパ管造影を施行. リンパ漏出部位は同定できなかったが, 造影後急速に胸水は減少し8日目には胸水流出は止まり, 術後158 日に退院となった. リピオドールリンパ管注入は漏出部位同定困難な乳糜漏に対する効果の高い新しい治療法の一つとして期待される.

Background The objectives of the present study are to determine the long-term changes in glucose tolerance function after pancreaticoduodenectomy and to compare the effects of pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG). Patients and methods The present study consisted of 51 patients who received a pancreaticoduodenectomy for tumors of the pancreatic head area and survived more than 7 postoperative years without tumor recurrence. According to the type of pancreatic anastomosis, they were classified into 2 groups of 25 PJ patients and 26 PG patients. Changes in the patterns of a 75-g oral glucose tolerance test (OGGT) (normal, impaired glucose tolerance [IGT], and diabetic [DM] patterns) and the need for beginning diabetic treatment (oral hypoglycemic agents or insulin) were compared between groups. Results Within 3 months after surgery, 14 (56%) patients in the PJ group had normal OGTT patterns, 8 (32%), IGT patterns, and 3 (25%), DM patterns. In the PG group, the patterns of OGTT were similar with 16 (62%) normal patterns, 6 (23%) IGT patterns, and 4 (15%) DM patterns. During the first 7 postoperative years, the 2 groups showed similar results: (1) none of the patients with normal patterns developed functional decline in glucose tolerance; (2) a high percentage of patients with initial IGT or DM patterns developed worsening glucose intolerance (7 [64%] of 11 PJ patients vs 7 [70%] of 10 PG patients); (3) the onset of functional decline in glucose tolerance occurred predominantly within the first 3 postoperative years; and (4) no specific causative event prior to the subsequent functional decline was detected. Conclusion The decline of glucose tolerance after pancreaticoduodenectomy seems to be associated with a low reserve of endocrine function rather than anastomotic procedures or their related complications. Regardless of the types of pancreatic anastomosis, a close follow-up of glucose tolerance function is recommended during the first 3 postoperative years, especially among IGT or DM patients.

We report a case of long-term survival after combination chemotherapy and surgical resection of a cancer of unknown primary site[ CUPs]. A septuagenarian female was identified as having high blood levels of carcinoembryonic antigen (CEA) during follow-up monitoring of asthma. Endoscopy and imaging studies including computed tomography (CT) and positron emission tomography (PET)-CT revealed a malignant lymph node adjacent to the abdominal aorta; however, no other lesion was detected. Therefore, we performed CT-guided biopsy and diagnosed the lesion to be a lymph node metastasis of poorly differentiated adenocarcinoma. As we considered this as a systemic disease, the patient received 2 courses of combination chemotherapy with 5-fluorouracil( 5-FU)/cisplatin( CDDP) and achieved a partial response (PR). Later, the patient received S-1 therapy as second-line chemotherapy and S-1/irinotecan( CPT-11) as third-line chemotherapy in an outpatient clinic. However, the tumor continued to grow, and therefore, we decided to perform surgical resection. Histopathological examination of the resected specimen yielded a diagnosis of metastatic adenocarcinoma of the lymph node. The patient has been well without any signs of recurrence for more than 9 years since surgery. As CUPs is generally associated with poor prognosis, this case raises the possibility that combination therapy might improve convalescence.

A 63-year-old man visited our clinic with a chief complaint of a left axillary mass, and after a series of examinations, gastric cancer was diagnosed. Histopathological examination revealed a human epidermal growth factor receptor (HER)-2- positive( immunohistochemistry[ IHC], 2+; fluorescence in situ hybridization[ FISH], positive) poorly differentiated adenocarcinoma, and SPT therapy( S-1 at 120 mg/m2/day+cisplatin[ CDDP] at 60 mg/m2+trastuzumab at 8 mg/kg) was initiated. The primary lesion and swollen lymph nodes initially decreased markedly in size; however, the lymph node swelling worsened at 186 days( 6.2 months) after the initiation of treatment. Progressive disease( PD) was diagnosed, and SPT therapy was terminated. One cycle of S-1+docetaxel was administered as second-line therapy, but the regimen was changed to docetaxel monotherapy due to adverse effects. After 5 cycles of this treatment, the primary lesion had decreased in size and the lymphadenopathy disappeared. Positron emission tomography( PET)-computed tomography (CT) revealed fluorodeoxyglucose( F18)( FDG) accumulation only in the primary lesion, and therefore, with the patient's informed consent distal gastrectomy was performed approximately 14 months after the first treatment. The postoperative diagnosis was gastric cancer fStage IA (T1a, N0, and M0). Here, we discuss a case of HER2-positive gastric cancer with references. Among the advanced recurrent gastric cancers tested between April 2011 and February 2013, 16.4% (11/67) were HER2-positive.

Gastroduodenal stents for gastric outlet obstruction due to unresectable advanced gastric cancer are increasingly used; however, their effects have not been fully evaluated.A multicenter prospective observational study was performed. Patients were eligible if they had stage IV gastric cancer with a gastric outlet obstruction scoring system (GOOSS) score of 0 (no oral intake) or 1 (liquids only). Self-expandable metallic stents were delivered endoscopically. The effects of stents were evaluated.Twenty patients were enrolled and 18 were eligible (15 men, three women; median age, 70 years). Stent placement was successfully performed in all patients, with no complications. After stenting, a GOOSS score of 2 (soft solids only) or 3 (low-residue or full diet) was achieved in 13 (72%) patients. An improvement in the GOOSS score by one or more points was obtained in 16 (94%) patients. The median duration of fasting and hospital stay was 3 (range, 0-9) days and 18 (6-168) days, respectively. Chemotherapy was performed after stenting in 13 (72%) patients.Gastroduodenal stents are thought to be feasible, safe, and effective for gastric outlet obstruction due to unresectable advanced gastric cancer, with rapid clinical relief and a short hospital stay.

A patient is a 62-year-old man who was presented by epigastralgia. He was pointed out super advanced gastric cancer with paraaortic lymph node metastasis and pancreatic invasion by gastrointestinal endoscopy (GIS) and computed tomography (CT). We diagnosed as cT4N3M0, and started with chemotherapy as follows. S-1 (120 mg/day) was orally administered for 3 weeks followed by 2-week rest as one course, and CDDP (90 mg/body)was administered by intravenous drip on day 8. Partial response was indicated after 6 courses of this procedure. We changed the procedure to S-1 single treatment for 2 weeks followed by 2-week rest. After 12-course of this procedure, he was attacked by brain infarction, the procedure was interrupted for about 8 months. After rehabilitation, an S-1 single treatment was restarted. The main tumor and metastatic lymph node appeared no change before the interruption of S-1 single treatment. So, we considered that complete response was continued. S-1+CDDP and S-1 single regimen appears to be effective for super advanced gastric cancer.

Purpose Currently, preoperative chemoradiotherapy followed by surgery is the only promising strategy for patients with T4 esophageal cancer. This study retrospectively analyzed the prognostic factors in patients with curatively resected cancer after chemoradiotherapy. Patients and Methods Between September 1989 and December 2003, 42 patients with T4 esophageal cancer received preoperative chemoradiotherapy (CRT) followed by curative surgery. Chemotherapy consisted of 5-fluorouracil/cisplatin (FP) or 5-fluorouracil/adriamycin/cisplatin (FAP). A total dose of 40 Gy of radiation was delivered concurrently. Surgery was scheduled 4 weeks after the completion of CRT. The treatment response was categorized using general criteria. Toxicities of the CRT were assessed according to National Cancer Institute of Common Toxicity Criteria (NCI-CTC). Univariate and multivariate analyses were performed to identify significant prognostic clinicopathological factors. Results The overall survival rate was 38.4% at 5 years. The toxic grade for leukopenia (grade 0–2/3–4) and pathological effect (grade 3/1–2) were significantly different by univariate analysis (P = 0.03 and 0.05, respectively). Multivariate analysis identified the toxic grade for leukopenia as the only significant and independent determinant of prognosis (P = 0.05). Conclusion In patients with T4 esophageal cancer who receive CRT followed by curatively resection, myelogenic chemotoxicity is a significant prognostic factor. J. Surg.

A 69-year-old man was diagnosed with squamous cell carcinoma of the lung, and underwent right upper lobectomy in October 2000. Histological findings were as follows: 2.5 cm in diameter, moderately differentiated squamous cell carcinoma of the lung, ly0, v0, n0, pT1N0M0, stage IA. No adjuvant therapies were performed. Multiple lung metastases were detected on CT scan in June 2001, and four cycles of chemotherapy with cisplatin+vindesine (day 1: cisplatin 100 mg/body, days 1, 8 and 15: vindesine 3 mg/body) were performed. The metastases were completely disappeared on CT scan in December 2001. No relapse has been seen for six years and two months.

Candida esophagitis rarely involves life-threatening complications, such as necrosis, perforation, or fistula formation between the esophagus and the airway. We herein report a case of Candida esophagitis complicated by esophagobronchial and esophagopulmonary fistulas. The patient in our study was a 70-year-old man with a 3-month history of dysphagia. Based on endoscopy and histological findings, he was diagnosed with a coinfection of Candida spp. and herpes simplex virus. Antifungal and antiviral therapy was administered without success. The esophagopulmonary fistula formation and a lung abscess were identified 7 months later. The patient was deemed intolerable to an esophagectomy due to his poor general condition, thus necessitating a two-stage operation. A cervical esophagostomy and a tube drainage of the thoracic esophagus were followed by an esophageal bypass using the pedicled jejunum via an antethoracic route. Although the lung abscess resolved, the inflammation of the esophagus persisted. A fistula between the esophagus and the left main bronchus eventually formed postoperatively and the patient died due to respiratory failure.

Brain metastasis, rarely observed as a tumor recurrence after curative surgery for thoracic esophageal cancers (TEC), has been increasingly observed with improvement of the clinical outcome of TEC.Records of 254 TEC patients who developed recurrent cancers after curative surgery during 1984-2002 revealed 11 patients (4.3%) with symptomatic brain metastasis, which were classified as five without extra-cranial disease (Brain type) and six with other metastatic diseases (Systemic type).Brain metastases were significantly associated with an advanced clinical stage and perioperative chemotherapy, which had been undergone by 73% of the brain metastasis patients, but only 23% for non-brain metastasis patients (p = 0.0008). Comparing to Systemic type, Brain type showed longer duration from esophagectomy to brain metastasis and tended to be more effective for perioperative chemotherapy. All Brain type but only two Systemic type brain metastases were removed by surgery. The average survival after brain metastasis was 17.7 months for the Brain type patients (two alive without tumor recurrence), but only 38.5 days for the Systemic type patients. The histological hallmark of Brain type metastasis was medullary tumor growth with mature tumor vessels, while Systemic type showed invasive tumor growth with naive capillaries.Postoperative brain metastasis in TEC patients is not rare, especially in an advanced clinical stage following perioperative chemotherapy. Surgical removal of brain metastasis might be the most promising treatment unless tumor metastasis in other organs is evident.

The patient was a 55-year-old female who underwent an abdomino-perineal resection for advanced lower rectal cancer. The tumor was a well differentiated adenocarcinoma, type 2 in the Japanese classification of colorectal carcinoma, and was measured 2.3 cm in size. Histologically, the tumor was considered to be stage IIIb (mp, n3(+), P0, H0, M(-)). She received adjuvant chemotherapy with 5'-DFUR. After 13 months from the surgery, the patient developed a hip pain. After 16 months from the surgery, a pelvic MRI scan revealed a 3 cm tumor in the perineum. Biopsy from the tumor revealed adenocarcinoma. Consequently, we diagnosed local recurrence in the perineum. Chemotherapy with CPT-11 (230 mg/body) and 5'-DFUR (800 mg/body) was administered for 2 cycles. Because the tumor was enlarged, high-dose rate interstitial brachytherapy was given to the recurrent site at a total dose of 54 Gy/9 fractions/5 days. There were no severe complications. CEA was decreased within normal range from a maximum of 9.3. No progress was detected on CT and MRI, and the hip pain had disappeared. The tumor marker is within normal range for about 2 years and QOL was improved. Hence, high dose rate interstitial brachytherapy appears to be effective for locally recurrent rectal cancer.

The patient was a male in the sixties who received interferon therapy against hepatitis C. At first, the patient was pointed to having an increased alpha fetoprotein (AFP) level of 1104 ng/ml. Partial hepatectomy was performed against hepatocellular carcinoma (HCC) (segment 3, 44 mm in diameter) and diagnosed by further exams. The serum AFP level decreased to a normal range after hepatectomy for the time being. A rapid elevation of serum AFP level (11,293 ng/ml) was observed nine months after the surgery. No evidence of recurrence in the intra- and extra hepatic organs such as adrenal gland, lung, bone, and brain except for intra abdominal solitary lymph node metastasis was observed. Then the metastatic lymph node was removed surgically. After the removal of the lymph node, the serum AFP level decreased within a normal limit immediately. This patient currently survives without the disease for 30 months after the initial operation, and for 19 months after a resection of the meatastatic lymph node.

The patient was a 69-year-old male. He had a 2-year history of subcutaneous tumor in the left axilla. Biopsy of the tumor showed the features of metastatic adenocarcinoma. FDG PET to check the primary lesion revealed the collection of an ileocecal junction and left axilla. After CT scan and colonoscopy, we diagnosed cecal cancer and metastasis of the axillary lymph nodes from it. He underwent ileocecal resection and a wide local resection of the axillary tumor. Histopathological examination showed the axillary tumor was different from the cecal cancer. Axillary tumor was diagnosed not as metastasis of axillary lymph nodes from cecal cancer but apocrine adenocarcinoma.

Lymph node metastasis is one of the strongest prognostic factors for patients with esophageal cancer. Whether neoadjuvant chemotherapy is effective for metastatic nodes and improves the prognosis of clinically node-positive patients is unknown. Seventy-seven patients with clinically node-positive esophageal cancer, who were given preoperative chemotherapy (5-fluorouracil, cisplatin and adriamycin) followed by surgery, were retrospectively analysed. The histological effectiveness of the chemotherapy against the main tumor in the resected specimen was correlated with nodal status and prognosis. Of the 77 patients, the histological effects in the main tumors were grade 3 in one patient (1.3%), grade 2 in 10 (13.0%), grade 1b in seven (9.1%), grade 1a in 50 (64.9%) and grade 0 in nine (11.7%). Eleven patients (14.3%) were found to be pathologically node-negative. The pathological stages were significantly earlier in responders (grades 3-1b) than in non-responders (grades 1a-0) (P = 0.0001). The responders showed a significantly lesser degree of lymph node metastasis (P = 0.0005), fewer metastatic nodes (2.2 +/- 3.1 vs. 12.0 +/- 20.5, P = 0.0482) and better survival (P = 0.002) than the non-responders. The most common failure pattern for the non-responders was lymphatic recurrence, with an incidence of 47.5% (28/59), while that for the responders was 16.7%. Responders to neoadjuvant chemotherapy show fewer metastatic nodes and better prognosis than non-responders. Neoadjuvant chemotherapy may offer clinical benefit to responders.

A 54-year-old woman complained of dyspnea, due to complete obstruction of the left main bronchus caused by recurrent esophageal carcinoma, was transferred to our department about two months after curative resection (with preoperative chemotherapy for T4 cancer) in July 2004. She suddenly developed a severe shortness of breath with anxiety, and arterial blood gas analysis revealed a PaO2 of 25 mmHg (FiO2 1.0). The presence of pulmonary embolism was diagnosed by pulmonary perfusion scintigraphy. Thrombolytic therapy with urokinase was started to keep the air way. Fogarty catheter and bronchoscopic Nd-YAG laser treatment was performed. After that, an expandable metallic stent (EMS) was placed at the site of obstruction without any troubles, and there was a striking improvement in her condition of respiration and atelectasis. The radiation therapy was initiated and completed safely. The tumor lesion had disappeared on CT scan after the radiation therapy (a total dose of 50 Gy). We experienced a case that could be rescued from an advanced respiratory failure caused by one side air way obstruction and another side's blood circulation disorder.

This case is about a male in his 50's. In May 2004, he consulted a nearby doctor with abdominal pain and was pointed out a huge mass in the liver. He was diagnosed as hepatocellular carcinoma over 10 cm in diameter with chronic hepatitis type B. Because the tumor concurred with intra-hepatic metastasis along with lymph node metastasis, we planned transhepatic arterial embolization (TAE) as a first choice of treatment and performed twice. However, because of the tail inside part of the tumor was supplied from the gastroduodenal artery (GDA) and right gastroepiploic artery (RGEA) which were nutrient arteries, an effective TAE was impossible. The enhancement lesion that seemed viable was shown by enhanced CT. Therefore, a wrapping therapy (surgical decollateralization+silicon membrane sheeting) was performed under laparotomy for the purpose of cutting off blood supply to the part of the viable lesion in August of the same year. The tail inside part of the tumor that seemed viable fell into necrosis by wrapping alone, and the serum PIVKA-II level decreased within normal limit. As of ten months after the treatment, the patient is still alive without aggravation.

The patient was a 64-year-old female who underwent an abdomino-perineal resection for advanced lower rectal carcinoma. The tumor was a mucinous adenocarcinoma, type 2 in the Japanese classification of colorectal carcinoma, and was measured 4.5 cm in size. Histologically, the tumor was considered to be stage II (a2, n1, P0, H0). She received adjuvant chemotherapy with 5-FU/LV. After 7 months from the surgery, the patient developed a hip pain. Pelvic CT scan revealed a 4.5 x 6.0 cm mass anterior to the sacrum. Consequently, a diagnosis of local recurrence with sacrum invasion was made. An operation, involving tissue expander placement in the pelvis and pelvic floor was made by dexon mesh, was performed. Radiotherapy was given to the pelvic region at a total dose of 65 Gy (given 2.5 or 3 Gy each x 25 fragments). Chemotherapy with CPT-11 (100 mg/body) and 5'-DFUR (800 mg/body) was administered for 3 cycles. CEA (ng/ml) was decreased within a normal range from maximum 13.8. No progression was detected on CT, and Hip pain had disappeared. Abscess in the pelvis by tumor necrosis was managed conservatively. In this case, tumor marker is within a normal range over 2 years and QOL was improved, suggesting that chemoradiation with a tissue expander may be effective.

For gastric cancer patients who have no peritoneal seeding at a macroscopic level but positive results in the peritoneal lavage cytology (PLC), the prognostic benefit expected by surgical resection is still controversial. During the period 1975-1994 as series of 417 consecutive patients without distant organ metastases underwent surgical resection for gastric cancer that had invaded the subserosal or deeper layers of the stomach wall. Immediately after laparotomy, the pouch of Douglas was washed with 100 ml of physiologic saline solution, and the fluid was collected for cytologic examination (four slide glasses) using Giemsa and Papanicolaou staining methods. According to the macroscopic (P) and cytologic (Cyt) results, the 417 patients were classified into three groups: P(+) (n = 97); P(-)/Cyt(+) (n = 25); and P(-)/Cyt(-) (n = 295). Their 3-year survival rates after surgical resection were 4%, 24%, and 48%, respectively (p = 0.0001: P(-)/Cyt(+) vs. P(-)/Cyt(-); p = 0.0018: P(-)/Cyt(+) vs. P(+). Among the 25 P(-)/Cyt(+) patients, postoperative survival was not associated with the T stage, N stage, cellular atypism, or cluster formation but with the number of cancer cells per slide during PLC. The 3-year survival rate was 35% for the subgroup with fewer than 10 cancer cells per slide (17 patients) and 0% for the other subgroup with 10 or more cancer cells per slide (8 patients) (p = 0.017). For P(-)/Cyt(+) patients, who represent a subgroup of gastric cancer patients with an intermediate survival rate between the P(-)/Cyt(-) and P(+) patients, the number of cancer cells observed during PLC offers a potent prognostic indicator for the gastrectomy.

The site of surgical failure in cases of thoracic esophageal cancer (TEC) may be affected by the vertical location of the cancer in this longitudinal organ, suggesting the need to select the mode of adjuvant therapy based on location. We classified 501 TECs (92% squamous cell carcinomas) that underwent curative surgery without preoperative treatment as 13% upper thoracic (Ut), 51% middle thoracic (Mt), and 36% lower thoracic (Lt) lesions. Recurrent disease was discovered in 180 (36%) of the patients during a postoperative survey, most frequently in the cervical nodes (19%), liver (18%), abdominal paraaortic nodes (17%), and upper mediastinal nodes (17%). Although postoperative survival rates were similar (5-year survival: Ut 51%, Mt 55%, Lt 54%), the tumor recurrence site was significantly affected by the TEC vertical location, with recurrence in the cervical and upper mediastinal nodes being most frequent for Ut and Mt cases and in the liver and abdominal paraaortic nodes for Lt cases. Insufficient surgical lymph node clearance could be assessed by the recurrence index (RI), defined as the frequency of metastasis at recurrence divided by that at surgery. The RI was significantly lower for the upper abdominal nodes (4%, 8/184) than the lower mediastinal nodes (15%, 19/123) or the upper mediastinal nodes (19%, 30/154). These findings indicated that regional tumor recurrence, corresponding to the surgical field, was more frequent in the Ut and Mt cases (53% and 51%) than the Lt cases (18%); and distant recurrence was more frequent in the Lt cases (62%) than in Ut or Mt cases (25% and 36%). Thus the vertical location of the thoracic esophageal cancer can be said to affected strongly the site of tumor recurrence after curative surgery. Regional radiotherapy might be expected to have an adjuvant effect on Ut/Mt tumors and systemic chemotherapy on Lt tumors.

Body weight loss is observed commonly after esophagectomy with gastric tube reconstruction in thoracic esophageal cancer patients. The functional and anatomical alteration of the stomach by this surgery should affect ghrelin secretion, a novel gastric hormone that upregulates body weight through appetite control and metabolic reaction.Early-phase postoperative alteration of serum ghrelin was measured before and at day 3 and day 7 after surgery in 9 patients. With 26 other patients, who had previously undergone surgery from 3 months to 67 months (mean, 25 months) before the present study period, the late-phase postoperative alteration of serum ghrelin was investigated along with postoperative body weight loss and serum leptin.Serum ghrelin concentration, which was equivalent to the control group before surgery (88.6 fmol/mL vs 97.5 fmol/mL) significantly decreased by half at 3 and 7 days after surgery. Thereafter, the serum ghrelin decline continued in the outpatients within 1 year after surgery (58.8 fmol/mL), while it was marginal in those from 1 to 3 years after surgery (77.2 fmol/mL). Serum ghrelin was significantly higher than the control after 3 years (185.1 fmol/mL). Thus, a significant positive correlation was observed between ghrelin and time after surgery (P.0001). Postoperative body weight loss was significant, averaged as DeltaBMI - 2.7 in the outpatients (P.0001). Until 3 years after surgery, a significant correlation between ghrelin and postoperative body weight loss was observed (P = .0152), with those having higher serum ghrelin showing less body weight loss. Serum leptin correlated well with body weight (P = .0144), but not with postoperative time, the degree of body weight loss, or serum ghrelin concentration.Gastric tube replacement for esophagectomy resulted in temporary reduction of ghrelin production, which is associated with body weight loss after surgery. The decline of ghrelin may play some role in the serious body weight loss after esophagectomy, thus encouraging clinical application of exogenous recombinant ghrelin for these patients.

Background Squamous cell carcinoma of the esophagus (ESCC) is radiosensitive; however, surgeons frequently encounter ESCC that survives radiotherapy to grow more rapidly and invasively. This alteration of tumor behavior may result from tumor hypoxia induced by radiotherapy. Methods Forty-four patients with advanced (T3 and T4) ESCC, who underwent radiotherapy before operation, either with 40 Gy for preoperative treatment or 60 Gy or more for radical treatment, and 44 patients without preoperative therapy were subjected to retrospective immunohistochemical study. CD34 for tumor vessels, glucose transporter 1 (GLUT1) which was induced by hypoxia, MIB-1 for proliferating activity, and p53 were stained for surgical samples from ESCC patients. Tumor tissue at the invading front was the focus of evaluation. Macroscopic morphologic differences of ESCC were also evaluated. Results Loss of esophageal wall thickness and deep ulceration were morphologic characteristics of ESCC after radiotherapy. Tumor vessel density was reduced and GLUT1 expression was greater in the ESCC after radiotherapy than in those without treatment. Tumor vessel density was similar for both preoperative and radical radiotherapy samples, while GLUT1 expression tended to be greater in the latter than in the former. The expression of MIB-1 and p53 did not show any significant difference between ESCC with or without radiotherapy. Conclusions Reduced vessel density and increased GLUT1 expression suggested tumor hypoxia for ESCC occurred after radiotherapy. Tumor hypoxia would induce ulcerative and invasive growth, which is a great obstacle to clinical treatment of residual or relapse ESCC after radiotherapy.

Background. Body weight loss is a common but one of the most serious sequelae after gastrectomy. Ghrelin, a novel gastric hormone that up-regulates body weight through appetite control and metabolic reaction, seems to be affected by gastric surgery. Patients and methods. Early postoperative alteration of serum ghrelin was evaluated at days 3 and 7 after gastrectomy for 13 hospital patients. In 64 outpatients who had previously undergone total gastrectomy (TG: 26 patients) or distal gastrectomy (DG: 38 patients) 4.6 months to 136 months (average, 41 months) earlier, the association between their serum ghrelin and leptin levels and postoperative body weight was investigated. Results. Serum ghrelin declined immediately and greatly after TG to 12% of the preoperative level (day 3 and day 7), whereas the decline was less significant after DG at 39% (day 3) and 56% (day 7). In outpatients, serum ghrelin after TG was very low compared with the control (18.6 fmol/mL versus 92.1 fmol/mL, P < 0.0001), irrespective of the period after surgery, whereas the level after DG recovered and was equivalent to the control (73.4 fmol/mL, P 0.355). Body weight loss was more apparent in TG patients than in DG patients, showing postoperative reduction of body mass index (BMI) ‐3.940 versus ‐1.949 (P < 0.0001). Serum leptin concentration, reflecting the systemic fat volume, significantly correlated with BMI in both TG and DG patients, and tended to be lower in TG patients than in DG patients (800 pg/mL versus 1158 pg/mL, P 0.236). Conclusion. Persistent decline of serum ghrelin and body weight was observed commonly after total gastrectomy. Further study is needed as to whether or not ghrelin administration can improve the body weight

We report a rare case of capillary hemangioma of the liver in an adult. The patient was a 55-year-old man, admitted for investigation of a hepatic tumor. The tumor was seen as a hypoechoic mass with a peripheral hypoechoic ring on ultrasonography. Computed tomography (CT) showed an enhancement pattern different from that of hepatocellular carcinoma (HCC) or cavernous hemangioma. Ultrasonography-guided biopsy was technically very difficult because the tumor was located just below the diaphragm. We could not establish whether the tumor was HCC or cavernous hemangioma by the imaging findings, so we performed a hepatic resection. Histopathological examination confirmed a diagnosis of capillary hemangioma. Ultrasonography, CT, and magnetic resonance imaging showed an intermediate pattern between cavernous hemangioma and HCC. Thus, we must be aware of the possibility of capillary hemangioma when finding an atypical liver tumor inconsistent with HCC or cavernous hemangioma.

Background Total removal of the gastric conduit (TRGC) due to gastric cancer after esophagectomy often results in high operative morbidity and mortality rates, especially when done in the posterior mediastinum. This is one of the reasons for the retro-sternal or subcutaneous route being preferred for gastric conduit replacement in esophageal cancer operation. Patients Five out of 680 post-operative esophageal cancer patients underwent TRGC via thoracotomy and laparotomy due to posterior mediastinal gastric conduit cancers. Results In these patients, advanced gastric cancers were found at an average of 84 months (ranging 57–136 months) after esophageal cancer surgery and preoperative risk factors for TRGC were found in age, nutrition, and pulmonary function. The operative time for TRGC was long (average 670 min) but not associated with operative complications, while blood loss varied among patients, with one with the most operative blood loss dying after surgery due to pyothorax and renal failure. This case, and another early case subjected to TRGC first with thoracotomy then followed by laparotomy, showed more operative blood loss (10,895 and 3,260 ml) than the later three patients (2,370, 1,900, and 1,780 ml), who underwent laparotomy before thoracotomy with ligation of the blood supply of the gastric conduit and lysis of adhesion around gastric conduit in the lower mediastinum from the abdomen. Conclusion TRGC in the posterior mediastinum would be safer if operative manipulation were started from laparotomy in order to reduce operative blood loss. J. Surg.
