Introduction: Various potential prognostic histopathologic factors for colorectal carcinoma liver metastasis have been proposed. However, there is still no consensus on pathological reporting of colorectal carcinoma liver metastasis resection materials. The aim of this study was to investigate the relation between selected tumoral and parenchymal histopathologic features and prognostic factors for better characterization and prognostic prediction of the patients with colorectal carcinoma liver metastasis. Methods: Hematoxylin-eosin stained slides from 100 patients who underwent hepatic resection were evaluated. Pathologic characteristics; including number of tumor nodules, largest tumor size, status of surgical margin, tumor distance to closest margin, tumor necrosis, the presence of tumor capsule, tumor differentiation, perineural and lymphovascular invasion, micrometastasis, tumor budding, peritumoral lymphocytic infiltrate and parenchymal features including steatosis, steatohepatitis, lobular inflammation, confluent necrosis, hepatocyte ballooning, portal inflammation were assessed. For 49 patients who were treated with preoperative chemotherapy, tumor regression grade and chemotherapy-related parenchymal changes such as sinusoidal damage, venous obstruction, nodular regenerative hyperplasia, steatosis and steatohepatitis were also evaluated. Results: The presence of lymphovascular invasion (p < 0.001), micrometastasis (p=0.004), absent or mild peritumoral lymphocytic infiltration (p =0.013), high tumor budding score (p=0.033) and moderate/poor differentiation (p=0.022) were significantly associated with shorter overall survival. Lymphovascular invasion (p < 0.001) was an independent predictor of mortality in multivariate analysis. Conclusions: We conclude that tumor differentiation, lymphovascular invasion, micrometastasis, peritumoral lymphocytic reaction and tumor budding score are potential prognostic histopathological features and candidates for inclusion in pathology reports of colorectal carcinoma liver metastasis resections.

Data on peritumoral histopathologic findings in patients with hepatocellular carcinoma (HCC) is limited. In this retrospective study, we evaluated the peritumoral histopathologic changes in patients with chronic viral hepatitis (CVH)-associated HCC (CVH-HCC) and their prognostic value. 61 consecutive cirrhotic patients who underwent liver transplantation due to CVH-HCC were included. Histopathologic features within 1 cm distance of the tumor, and their association with clinicopathological characteristics and prognosis were evaluated. A random representative slide of cirrhotic parenchyma unrelated to invasive and/or dysplastic foci was also evaluated for the same histopathologic criteria. The majority (85%, n = 52) were male with a median age of 55 +/- 6.38 (range, 39-67). The etiologic agent was only HBV in 90% (n = 55). The most common peritumoral findings were portal inflammation (100%; n = 61), ductular reaction (100%; n = 61) and sinusoidal dilatation (95%; n = 58). Macrovascular invasion was observed only in four cases (7%) with mild peritumoral portal inflammation. Neutrophilic infiltration of the peritumoral portal tracts (n = 18; 30%) was significantly associated with pT4 tumor stage, tumor grade, macrovascular invasion, and pretransplant therapy. Patients with moderate or severe peritumoral sinusoidal dilatation tended to have worse prognosis, albeit not significantly. Peritumoral ballooning degeneration was associated with multifocality, recurrence and recurrence-free survival in both uni- and multivariate analysis. Peritumoral histopathologic changes in CVH-HCC can be classified as: changes related to pathogenesis, changes indirectly affecting prognosis, and changes directly affecting prognosis. Peritumoral prominent ballooning degeneration may be a predictor of recurrence while portal neutrophilic infiltration and sinusoidal dilatation seem to indicate poor prognosis.

Aim:Peritoneal Surface Disease Severity score (PSDSS) has been used in the evaluation of patients who are scheduled for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal metastasis of colorectal origin (PMCO). The aim of this study was to evaluate the validity of PSDSS in predicting prognosis in patients who underwent CRS + HIPEC for PMCO at our center.Method:Demographic data, operation data, histopathological features, perioperative morbidity and mortality, and oncologic follow-up data were obtained retrospectively from the database and analyzed. Peritoneal carcinomatosis index (PCI) values were calculated from preoperative computed tomographies. PSDSS was calculated by evaluating clinical symptoms, PCI and histology of primary tumor. Two PSDSS groups were formed: PSDSS 1 and 2 groups as low PSDSS group, and PSDSS 3 and 4 groups as high PSDSS group.Results:Sixty-one patients, including 36 females (59%) and 25 males (41%), with PMCO who underwent CRS and HIPEC were included in the study. Forty-four patients were enrolled to the low PSDSS group and 17 patients were enrolled to the high PSDSS group. Three patients (3.2%) died during the perioperative period. Twenty-one patients (34.4%) had perioperative complications. The mean follow-up was 35.0±23.2 months. During the follow-up period, 36 patients (59%) had recurrence and 44 patients (72.1%) died. The mean survival was 46.5±5.5 months, and 1-,3- and 5-year survival rates were 85%, 47% and 21%, respectively. There was no correlation between low and high PSDSS groups in terms of morbidity and recurrence (p=0.486 and p=0.385, respectively). Mortality was more frequent in high PSDSS group (94% vs. 63%; p=0.024). The mean survival of patients in the low PSDSS group was significantly longer than in the high PSDSS group (57.2±6.7 months vs. 16.5±2.6 months; p=0.001).Conclusion:The findings of this study demonstrated the validity of PSDSS in predicting prognosis in patients with PMCO who were scheduled for CRS and HIPEC.

The issue of performing an anastomosis of the anterior sector veins to the vena cava in living donor liver transplantation is still controversial. We aimed to research whether there was any difference in terms of complications, rejections, and graft survival between patients with and without anterior sector venous drainage to the vena cava.Patients were retrospectively investigated for demographic data and ratio of graft needed to available graft weight. Donors had volumetric calculations and middle hepatic vein anterior sector drainage documented in detail.Seventy-three donors with middle hepatic vein drainage were included. Thirty-five had anterior sector venous drainage performed and 38 patients did not have drainage procedures performed. The incidence of general complications was higher in the group without anterior sector drainage (78.3% and P = .002). Biloma linked to bile leaks were observed in 8 patients without drainage (72.8%) and 3 patients with drainage (27.2%). Late acute rejection occurring during follow up after transplantation was identified in 28 patients (11.6%). Of these, 1 (14.3%) had anterior sector drainage and 6 (85.7%) were in the patient group without drainage (P = .067).As a result of this study, for patients with grafts at the volume limit (graft weight to receiver weight ratio 0.8) and with congestion observed in the anterior sector after liver implantation and for patients with outflow problems identified on Doppler ultrasonography, anterior sector veins5 mm should definitely be drained into the vena cava. Hence, both complication and rejection rates will reduce, and we can lengthen the graft, and thus patient, survival.

Aim Small-for-size grafts have become more important, especially in living donor liver transplants. The Pringle maneuver, used to reduce blood loss, and the immunosuppressive medications used to prevent graft rejection in liver transplants have different side effects on liver regeneration. We researched the effect of situations where tacrolimus and the Pringle maneuver were applied or not on liver regeneration in rats with partial hepatectomy. Material and Methods This study was completed with 35 Wistar Albino rats. The subjects were randomly divided into 5 groups: Group 1 had the abdomen opened and no other procedure was performed; Group 2 underwent a 70% hepatectomy; Group 3 underwent a 15-minute Pringle maneuver + 70% hepatectomy; Group 4 underwent a 70% hepatectomy + 5 days of 1 mg/kg/day intraperitoneal tacrolimus; and Group 5 underwent a 150 minute Pringle maneuver + 0% hepatectomy + 5 days of 1 mg/kg/day intraperitoneal tacrolimus. All rats were sacrificed on the seventh postoperative day, remaining liver tissue was weighed, and weight indices created. The remaining liver tissue was stained with phosphohistone H3 and the mitotic index calculated. Results The groups that underwent the Pringle maneuver, 70% hepatectomy, and tacrolimus administration were compared with the control group in terms of mitotic index and weight index, but no statistically significant differences were identified. Conclusion Suppression of regeneration forms a risk after liver transplantation with small-volume grafts. As a result, research on the effect of tacrolimus combined with the Pringle maneuver is important, especially for transplantations using segmented liver grafts. In our study, we showed that the use of tacrolimus had no negative effect on liver regeneration.

OBJECTIVES Our objective was to analyze characteristics, risk factors, and incidence of de novo malignancies after liver transplant. MATERIALS AND METHODS The hospital records of 557 patients who underwent liver transplant were analyzed from the point of de novo malignancy development. We evaluated the demographic features and survival of these patients retrospectively. RESULTS The research covered 429 patients, 9 (2%) of whom developed de novo malignancy. All of these patients were male (100%), and their mean (SD) age was 51.33 (4.69) years (range, 45-65 y). Indications for transplant included alcohol related in 4 cases, chronic hepatitis B in 2 cases, chronic hepatitis B and C in 1 case, chronic hepatitis B and D in 1 case, and chronic hepatitis C and alcohol-related cirrhosis in 1 case. The mean (SD) time from transplant to cancer diagnosis was 63.41 (37.10) months (range, 17-122 mo). The types of tumors were lung cancer, lymphoma, neuroendocrine tumor of lung, nasopharyngeal cancer, and squamous cell carcinoma of the skin. Seven cases received chemotherapy with or without radiotherapy. Two cases received surgery and radiotherapy. One patient underwent surgical treatment. One patient died before treatment was started. CONCLUSIONS In recent years, improvements in surgical techniques and immunosuppressive therapies have helped prolong survival of patients who undergo liver transplant. However, this also has led to a rise in the incidence of long-term complications such as de novo malignancy. These patients are more likely to develop de novo malignancy than the general population, for which chronic immunosuppression is identified as a major risk factor. Early diagnosis and treatment of de novo malignancies can help obtain better prognosis and higher survival rates in these patients.

Objectives Hepatic resection and liver transplant are regarded as 2 potentially curative treatments for hepatocellular carcinoma. Here, we compared both options in patients with hepatocellular carcinoma secondary to cirrhosis seen at a single center over 12 years. Materials and methods We evaluated early complications and survival of patients with hepatocellular carcinoma treated with liver transplant (57 patients) or hepatic resection (36 patients) at our center between 1998 and 2010. Results The 34-month mean follow-up period was similar for both treatment groups. The liver transplant group had a longer hospital stay than the hepatic resection group (P ⟨ .001). Patients with Child-Turcotte-Pugh A stage were treated by hepatic resection more than by liver transplant (P ⟨ .001),with Child-Turcotte-Pugh B stage patients treated by liver transplant more than by hepatic resection (P = .03). All patients with Child-Turcotte-Pugh C stage had liver transplant. Both treatment groups had similar postoperative complications and early postoperative mortality rates, but liver transplant resulted in longer overall (P = .001) and higher event-free (P = .001) survival than hepatic resection. Among the liver transplant group, 57.8% of patients met the Milan criteria. Patients who met Milan criteria were treated by liver transplant statistically more than hepatic resection, and these patients had longer overall survival (P = .01) and higher event-free survival (P ⟨ .001) than patients who had hepatic resection. Hepatocellular carcinoma recurrence rates were higher after hepatic resection (P = .232). Conclusions In patients with hepatocellular carcinoma, hospital stay was longer after liver transplant, but morbidity and mortality rates for liver transplant versus hepatic resection were similar. However, overall and event-free survival rates were better after liver transplant than after hepatic resection. These results suggest that liver transplant should be considered as the primary treatment option for patients with hepatocellular carcinoma secondary to cirrhosis.

Objectives We investigated late mortality causes and risk factors in patients who were undergoing deceased-donor liver transplant. Materials and methods Patients who had deceased-donor liver transplant from February 1997 to June 2014 in the hepatopancreaticobiliary surgery and liver transplant unit at Dokuz Eylul University Hospital were analyzed. Inclusion criteria were patients over 18 years of age and who survived more than 1 year after liver transplant. Causes of mortality and related risk factors after the first year were analyzed. Results Of the 157 included patients, 102 patients (72%) received transplant procedures for hepatitis B and C secondary to chronic liver disease. Mean follow-up was 89.85 months (range, 14.4-240 months). Of 157 patients, 20 patients (12.7%) died: 12 patients (60%) died during posttransplant years 2-5 and 8 patients (40%) died after 5 years. Causes of death included malignancy in 8 patients (40%), recurrent hepatitis C infection in 3 patients (15%), infection in 3 patients (15%), coronary artery disease in 2 patients (10%), graft rejection in 2 patients (10%), and biliary complications in 2 patients (10%). Univariate analyses showed that long-term survival was significantly lower in patients older than 50 years (P = .001), when there was presence of hepatocellular carcinoma (P = .011), and when donor age was higher than 38 years (P = .045). Multivariate analyses identified recipient age (P = .007) and presence of hepatocellular carcinoma (P = 0.033) as factors that reduced long-term survival. Conclusions The main causes of late mortality in liver transplant are malignancy, recurrence of hepatitis C, infection, coronary artery disease, graft rejection, and biliary complications. Advanced age and hepatocellular carcinoma are independent risk factors that increase late mortality.

Background The aim of this study was to evaluate the prognostic value of preoperative sarcopenia with regard to postoperative morbidity and long-term survival in patients with peritoneal metastasis from colorectal cancer treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Methods A longitudinal cohort study was conducted on patients with peritoneal metastases of colorectal origin treated with CRS-HIPEC between 2008 and 2018. Data on patient demographics, body mass index, operative characteristics, perioperative morbidity and survivorship status and oncological follow-up were obtained from the hospital registry. Sarcopenia was assessed using preoperative computed tomography (CT) findings. Results Sixty-five patients [mean (SD) age: 54.4 (13.4) years, 64.6% females] were included in the study. Sarcopenia was evident in 30.8% of patients, while mortality rate was 66.2% with median survival time of 33.6 months. Presence of sarcopenia was associated with older age (59.6 (9.2) vs. 52.1 (14.4) years, p = 0.038), higher likelihood of morbidity (70.0% vs. 35.6%, p = 0.015) and mortality (90.0% vs. 55.6%, p = 0.010) and shorter survival time (17.7 vs. 37.9 months, p = 0.005). Cox regression analysis revealed that the presence of sarcopenia (HR 2.245, 95% CI 0.996-5.067, p = 0.050) was a significant predictor of increased likelihood of mortality. Conclusions Preoperative sarcopenia is an independent prognostic factor of postoperative morbidity and shorter survival in CRC peritoneal metastasis patients treated with CRS-HIPEC. Our findings support the importance of preoperative screening for sarcopenia as part of preoperative risk assessment for better selection of CRS-HIPEC candidates or treatment modifications in CRC patients with peritoneal metastasis.

OBJECTIVE Seroma occurs as a result of accumulation lymphovascular liquid in the dead space forming after tissue dissection. It is the most common complication after breast surgery. Collagens are the common component of extracellular matrix and have an important role in wound healing. In this study, we aimed to investigate the efficiency of the Porcine Dermal Collagen in preventing Seroma. MATERIALS AND METHODS Eighteen young female Wistar rats were used and divided into three groups. Mastectomy and axillary dissection were performed in each group. No other procedures were performed in Group 1 (Control group). Porcine dermal collagen was applied to 50% of the mastectomy field in Group 2 and to 100% of the mastectomy field in Group 3. RESULTS Seroma volume was significantly decreased in Group 3 in contrast to Groups 1 and 2 (p

Introduction We investigated the liver transplantation literature since 1975 and found the most frequently cited 100 articles and assessed the distribution of authors and journals of these articles. Method Using the advanced mode of the Institute for Scientific Information (ISI) Web of Science (WOS) search engine, the words “SU = transplantation AND TI = liver OR SU = transplantation AND TS = liver” were used to scan articles and determine the most-cited 100 articles on July 18, 2016. Results From 1975 to date, it appears a total of 43,369 articles were published in the field of liver transplantation in the WOS. Although the most cited article had 677 citations, the least cited article had 180 citations. The mean citation number for the 100 articles was 252.31 ± 96.75. The mean annual citation number for the articles varied from 61.55 to 5 and the mean was 15.31 ± 8.63. The most cited article was by Feng et al “Characteristics Associated With Liver Graft Failure: The Concept of a Donor Risk Index” published in the American Journal of Transplantation (677 citations). Conclusion Bibliometric analysis highlights the key topics and publications that have shaped the understanding and management of liver transplantation. According to our research, this is the first study to investigate articles with most citations in the field of liver transplantation. In our study the article with the most citations was cited 677 times, whereas the 100th article was cited 180 times with a mean citation number for the 100 articles of 252.31 ± 96.75.

Introduction Living donor liver transplantation (LDLT) is performed with increasing frequency worldwide due to the shortage of donated organs. It is a life-saving procedure for the recipient, but, on the other hand, a major surgical procedure for healthy donors and it may cause morbidity and even mortality. Patients and Methods This research was completed at Dokuz Eylul University Faculty of Medicine Hospital General Surgery Department Liver Transplant Unit and included 280 cases (4 with simultaneous liver and kidney transplants from living donors) who underwent donor right hepatectomy for LDLT from June 2000 to June 2016. We analyzed the data of patients retrospectively. Results Of 280 donor right hepatectomies for LDLT, 181 were male (M; 64.6%) and 99 were female (F; 35.4%) (M/F: 1.82). Mean donor age was 31.2 ± 0.9 years (range, 18–56). Mean donor monitoring duration was 45 ± 2.4 months (range, 3–192 months). Mean body mass index (BMI) was 24.28 ± 2.96 kg/m2 (range, 18.1–32.42 kg/m2). In our study 72 cases (25.7%) developed postoperative complications. There were 17 Clavien grade 3A, 1 grade 3B, and 5 grade 4A complications and also 1 death due to pulmonary embolism. Conclusion Together with the increase in living donor surgery, the morbidity and mortality of these cases are becoming controversial. Full donor safety is only possible with appropriate donor choice requiring very detailed studies, a problem-free hepatectomy process, and close postoperative donor monitoring.

Introduction In living donor liver transplantation (LDLT), hepatic arterial continuity is crucial to avoid biliary leakage, biliary stricture, cholangitis, and graft and patient loss. Sometimes there exist factors making anastomosis difficult or even impossible. In these cases, a vascular graft may be needed to bridge the two arteries for revascularization. Method Medical records of 297 patients who underwent LDLT between June 2000 and July 2016 at the Hepatopancreatobiliary Surgery and Liver Transplantation Unit of Dokuz Eylul University Hospital were reviewed retrospectively. Twenty-eight (9%) patients younger than the age of 18 were excluded from the study. The remaining 269 patients were included in the study. We analyzed data of patients who developed hepatic arterial complications during or after LDLT and underwent revascularization using autologous interposed inferior mesenteric artery (IMA) grafts. Results In 8 (2.9%) of the 269 patients who underwent LDLT and were included in the study, autologous interposed IMA grafts were used for the hepatic artery revascularization. All of the patients were males. Their mean age was 42 (range, 25–57). The mean duration of follow-up was 83.25 months (range, 3–144 months). One patient developed intraoperative hepatic arterial thrombosis (HAT) after autologus IMA reconstruction and this patient needed retransplantation. No arterial complications developed in the other 7 patients. Conclusion Autologous interposed IMA graft could be used as an alternative vascular graft in hepatic artery revascularization to provide tension-free hepatic arterial continuity.

Aim Liver transplantation (LT) is the most promising treatment method in hepatocellular cancer (HCC). Due to the shortage of organ donors and the possible risks associated with living donation, the selection of patients for LT is critical. The aim of this study is to investigate the predictive ability of the Glasgow Prognostic Score (GPS), modified GPS (mGPS), and hepatic GPS (hGPS) on prognoses in a patient group who underwent deceased donor LT (DDLT) or living-donor LT (LDLT) for HCC. Patients and Methods This study includes 62 DDLT and 55 LDLT patients who underwent LT for HCC between 1998 and 2016 in a single center. The study endpoints were recurrence, 0- to 1-year mortality, 0- to 3-year mortality, mortality, and overall survival (OS). Results The median follow-up time was 70.24 ± 48.47 months. GPS and hGPS positivity were found to be prognostic indicators of 0- to 3-year mortality and overall mortality in DDLT (P = .012, P = .006; P = .044 and P = .022 respectively). In the LDLT group, GPS was found to be effective in predicting 0- to 1-year and 0- to 3-year mortality (P = .045, P = .022 respectively); GPS and hGPS were also found to be effective in predicting overall mortality (P = .001 and P = .046 respectively). The OS was significantly longer in the GPS 0 group and hGPS 0 group compared to the GPS 1-2 and hGPS 1-2 group in both DDLT and LDLT. Conclusion The findings of this study and the literature indicate that using GPS and hGPS is appropriate in selecting patients with HCC who are candidates for LT.

Aim There is a well-known risk of the emergence of hepatic failure in living donor transplant cases on whom are performed a right donor hepatectomy (RDH). There are different prevalence ratios in literature on this phenomenon. In our study, we aim to depict the prevalence of hepatic failure and risk factors in our cases regarding the most recent description criteria related to hepatic failure. Patients and Methods We included right liver donor hepatectomy cases who fit the donor evaluation algorithm at the Dokuz Eylul University Liver Transplantation Unit between the period of June 2000 and September 2017. The patients were evaluated regarding preoperative data. Liver failure was defined according to the International Study Group of Liver Surgery (ISGLS) criteria. We also included statistical analysis of risk factors that are potentially related to liver failure. Results We included a total of 276 patients. In 27 (9.7%) patients, we observed posthepatectomy liver failure (PHLF). In 26 (9.4%) patients, we observed Grade A liver failure; in 1 (0.3%) patient, we observed Grade B liver failure. We did not observe any Grade C hepatic failure. In patients with hepatic failure, we observed a significantly longer period of hospitalization (P = .007). Old age (odds ratio = 1.065, 95% confidence interval, 1.135–29.108, P = .035) and preoperatory red blood cell (RBC) transfusion (odds ratio = 5.749, 95% confidence interval, 1.019–1.113, P = .005) were shown as independent risk factors for PHLF. Conclusion Posthepatectomy liver failure is a vital complication of RDH. The risk can be decreased by careful selection of donor candidates. Elderly donor candidates and intraoperative RBC are independent risk factors for PHLF.

Objectives Vascular complications after liver trans-plant can be lethal. High levels of suspicion and aggressive use of diagnostic tools may help with early diagnosis and treatment. Here, we share our experiences regarding this topic. Materials and methods Adult and pediatric patients who had liver transplant between February 1997 and June 2018 in our clinic were included in the study. Patients were grouped according to age (pediatric patients were those under 18 years old), male versus female, indication for transplant, type of liver transplant, type of vascular complication, treatment, and survival after treatment. We analyzed the statistical incidence of vascular complications according to age, male versus female, and type of liver transplant. Results Our analyses included 607 liver transplant procedures, including 7 retransplants, with 349 (57.4%) from living donors and 258 (42.6%) from deceased donors. Of total patients, 539 were adults (89.8%) and 61 were children (10.2%). Vascular complications occurred in 25 patients (4.1%), with hepatic artery complications seen in 13 patients (2.1%) (10 adults [1.8%] and 3 children [4.9%]), portal vein com-plications seen in 9 patients (1.5%) (6 adults [1.1%] and 3 children [4.9%]), and hepatic vein complications seen in 3 patients (0.5%) (2 adults [0.36%] and 1 child [1.6%]). Rate of vascular complications was statistically higher in pediatric patients (11.4% vs 3.3%; P = .007) and higher but not statistically in recipients of livers from living donors (5.2% vs 2.7%; P = .19). Twelve patients (48.8%) were treated with endovascular approach, and 11 (0.44%) required surgical treatment. Two patients underwent immediate retransplant due to hepatic artery thrombosis. Conclusions Because vascular complications are the most severe complications after liver transplant, there must be close follow-up of vascular anastomoses, particularly early postoperatively, with radiologic methods. In cases of vascular complications, emergent treatment, including endovascular interventions, surgery, and retransplant, must be performed.

Stump closure is the most important part of a laparoscopic appendectomy (LA). Closing the appendix base with knot tying is the most cost-effective method. The defined risk factor for surgical site infection (SSI) after LA is the contamination of trocar entry area by inflamed appendicitis. This study aims to compare the single and double knot technique for stump control and specimen removal methods in LA.The data of patients who underwent LA between January 2015 and January 2017 were obtained from prospectively collected database. Single and double knot technique, specimen removal method, operation duration, hospital stay, and perioperative-postoperative complications were compared.Extracorporeal double knot was used in 134 patients (63%), and single knot was used in 79 patients (37%). There was no difference between operation duration in the two groups (p=0.97). No stump leakage was observed in any patient. Intraabdominal abscess developed in three patients (1.4%). Appendix was removed from the abdomen directly in 101 patients (47%) and using specimen retrieval bag in 112 (53%). SSI developed in five patients (2.3%), and appendices of all of these five patients were removed from abdomen without using specimen retrieval bag. No SSI was detected in the group that used the specimen retrieval bag (p=0.02).Single or double knot(s) tying can be defined as safe and cost-effective stump closure method. The risk of developing SSI can be reduced using specimen retrieval bag.

Aim: Liver transplantation (LT) is the most effective treatment method for preventing progressive and lethal complications of Wilson’s disease (WD). Despite the deceased donor liver transplantation (DDLT) and living donor liver transplantation (LDLT) are performed in many centers for WD, a limited number of reports were published, about long-term results. The aim of this study is to share the long-term outcomes of single center.Material and Methods: Patients who underwent LT for the WD, between 1997 and 2017 were included. Patient’s survival data, death causes, neurological symptoms and follow-up data were analyzed retrospectively.Results: Eighteen patients (8DDLT, 10LDLT) with the median age of 17.11±9.88 (6-43) were included. Donor relationship was familial in all LDLT patients. Median follow-up time was 80.57±67.59 (0.23-240.9) months and the median survival time was 173.74±25.13 months. Two patients (11.1%) died in the perioperative period (0-90 days) and totally 3 patients (16.6%) died in the postoperative 0-12 month’s period. The survival rates of the patient’s at 1-, 5- and 10 years were 83.3%, 75% and 67.3%, respectively. After LT, neurological symptoms disappeared in 6 of 7 patients and no improvement was observed in one patient. During follow-up period, chronic rejection was seen in 5 patients, 3 patients were treated with medical procedure and 2 patients died due to chronic rejection.Conclusions: Our findings are consistent with the literature, long-term survival is achieved in patients with no mortality, in the postoperative 0-12 month period and after LT, neurological symptoms are disappeared in most of the patients; according to this data, LT is an effective treatment method for the WD and complications.Keywords: Wilson disease; liver transplantation; long term results; living donor.

Aim This study aims to evaluate survival rates in elderly patients after liver transplantation (LT) and to analyze the factors associated with mortality. Patients and methods Our study includes 535 patients over the age of 18 who had undergone LT in our clinic between June 2004 and January 2018. Data were collected prospectively and scanned retrospectively. Data concerning the patients' age, sex, LT indication, Child-Turcotte-Pugh score, Model for End-Stage Liver Disease score, presence of hepatocellular cancer (HCC), coexisting disease, LT types, and post-transplant survival were investigated. The patients were grouped under 2 categories (18–59 years of age and 60 years of age and over) and were compared in terms of their characteristics. In patients aged 60 and over, the causes of mortality and related factors were investigated. Results The study included 535 patients, 458 (85.6%) of whom were between 18 and 59 years of age and 77 (14.4%) were over 60 years of age. The median follow-up period was 86.7 (1 to 247) months. The elderly group's survival rate was significantly lower than that of the younger group (P = .002). In elderly patients, survival rates of 1, 3, 5, and 10 years were 67.4%, 56.4%, 53.8%, and 46.1%, respectively. Conclusion In elderly patients, factors that increase post-LT mortality require thorough consideration. Equally important is the physiological status of the candidates for transplantation. Correct patient selection in the preoperative stage and good postoperative care can provide successful survival results in elderly patients.

Amaç: ‘’Geç dönemde ortaya çıkan akut rejeksiyon”(GOAR); canlı vericili karaciğer nakillerinde(CVKN) 6.aydan sonraki rejeksiyonlardır. Tanısında; karaciğer biyopsisi yerine daha az noninvaziv bir yöntem olan artmış kan Eozinofil sayısı prediktif bir biomarker olarak kullanılabilir mi? Yöntem ve Metod : Araştırmamızda Dokuz Eylül Üniversitesi Tıp Fakültesi Genel Cerrahi Karaciğer Nakli Biriminde Haziran 2000- 2017 yıllarında CVKN yapılan, 18 yaşından büyük ve en az 6 ay sağkalımı olan hastalar çalışmaya dahil edilmiştir.

Parastomal hernia is a frequent complication of an abdominal wall stoma. Surgical repairs have high complication and recurrence rates. Several different techniques have been suggested to prevent parastomal hernia during stoma creation. The aim of the present case–control study was to evaluate the efficacy of modified Stapled Mesh stomA Reinforcement Technique (SMART) for prevention of parastomal hernia compared with conventional colostomy formation in patients who underwent open or laparoscopic rectal resection and end colostomy for cancer. Between January 2014 and May 2016, all consecutive patients who underwent open or laparoscopic resection and end colostomy for primary or recurrent rectal cancer were identified from a prospectively collected database. Since January 2014, one surgeon in our team has routinely offered modified SMART procedure to all patients who are candidates for permanent terminal colostomy. In the SMART group patients, while creating an end colostomy, we placed a standard polypropylene mesh in the retromuscular position, fixed and cut the mesh by firing a 31- or 33-mm-diameter circular stapler and constructed the stoma. In the control group, a stoma was created conventionally by a longitudinal or transverse incision of the rectus abdominis sheath sufficiently large for the colon to pass through. Twenty-nine patients underwent parastomal hernia prophylaxis with modified SMART and 38 patients underwent end-colostomy formation without prophylaxis (control group). Groups were similar in terms of age, sex and underlying conditions predisposing to herniation. Median follow-up time is 27 (range 12–41) months. Nineteen patients (28.4%) developed parastomal herniation. In the SMART group, 4 patients (13.8%) developed parastomal herniation which is significantly lower than the control group in which 15 patients (39.5%) developed parastomal herniation (p = 0.029). We did not observe mesh infection, stenosis, erosion or fistulation in the SMART group. One patient in the control group underwent surgical correction of stoma stricture, another patient underwent surgery for stoma prolapse and four patients underwent surgery for parastomal herniation. New systemic reviews and meta-analysis support parastomal hernia prevention with the use of a prophylactic mesh. Until more evidence is available, prophylactic mesh should be routinely offered to all patients undergoing permanent stoma formation. SMART is easy to use, safe and effective for paracolostomy hernia prophylaxis.

Lymph node metastasis is a important factor on survival in ampullary adenocarcinoma. Log odds of positive lymph nodes (LODDS) is a novel prognostic indicator on lymph node status. We aimed to evaluate the prognostic impact of LODDS for the patients with ampullary adenocarcinoma who underwent R0 pancreaticoduodenectomy. The study includes 42 patients.. LODDS was calculated as "log (number of metastatic lymph nodes+0.5)/(number of total harvested nodes - metastatic lymph nodes+0.5)". LODDS subgroups were created based on their LODDS value: LODDS1(LODDS - 0.5). The mean survival time was 72.7 +/- 7.82 months. Survival rates for 1, 3 and 5 years were 93%, 65% and 45%, respectively. The mean LODDS value was -1.0466 +/- 0.51. LODDS subgroups show strong correlation with Overall Survival(OS). The mean survival were 114.8, 81.8, 56.6 and 25.6 months in LODDS subgroups 1, 2, 3 and 4, respectively (Log-rank; p = 0.002), in addition LOODS values shows correlation with perineural invasion and micro vascular invasion (p = 0.015 and p = 0.001 respectively). Findings in our patient group support the hypothesis that LODDS subgroups correlate with OS, and that value of LODDS has considerable role in prediction of OS as well.

BACKGROUND Stump closure is the most important part of a laparoscopic appendectomy (LA). Closing the appendix base with knot tying is the most cost-effective method. The defined risk factor for surgical site infection (SSI) after LA is the contamination of trocar entry area by inflamed appendicitis. This study aims to compare the single and double knot technique for stump control and specimen removal methods in LA. METHODS The data of patients who underwent LA between January 2015 and January 2017 were obtained from prospectively collected database. Single and double knot technique, specimen removal method, operation duration, hospital stay, and perioperative-postoperative complications were compared. RESULTS Extracorporeal double knot was used in 134 patients (63%), and single knot was used in 79 patients (37%). There was no difference between operation duration in the two groups (p=0.97). No stump leakage was observed in any patient. Intraabdominal abscess developed in three patients (1.4%). Appendix was removed from the abdomen directly in 101 patients (47%) and using specimen retrieval bag in 112 (53%). SSI developed in five patients (2.3%), and appendices of all of these five patients were removed from abdomen without using specimen retrieval bag. No SSI was detected in the group that used the specimen retrieval bag (p=0.02). CONCLUSION Single or double knot(s) tying can be defined as safe and cost-effective stump closure method. The risk of developing SSI can be reduced using specimen retrieval bag.

Morgagni hernia is a rare congenital anomaly arising from the fusion defect between the septum transversum and sternum. The diagnosis is usually difficult since the presentation may be asymptomatic or with respiratory symptoms, abdominal and/or retrosternal pain, abdominal fullness, or gastrointestinal obstruction. In this report, we discuss the clinical presentation and management of this rare condition in five consecutive cases. Between 2009 and 2015, five cases underwent surgery for Morgagni hernia (three laparoscopic and two open repair surgeries); one patient developed recurrent hernia 7 months after the laparoscopic surgery. This case is the first reported recurrence in literature following laparoscopic repair in adults. Surgery is the only treatment option for Morgagni hernias, which can be performed through transthoracic, transabdominal, laparoscopic, or thoracoscopic approach. The issues of using mesh and reducing the hernial sac remain controversial.

Introduction Because of the shortage of organs available for transplantation, living related sequential transplantation with the use of liver and a kidney from the same donor has emerged as a reasonable therapeutic alternative. However, there is insufficient literature about the complications that living donors experience after simultaneous kidney and liver transplantations. Methods From December 2001 to October 2009, 5 living donors provided simultaneous donation of livers and kidneys and 1 living donor donated first her kidney and then her liver. Demographic data of the donors and information concerning the surgery and postoperative observation were collected prospectively. Results All of the donors were female. The median age was 27.5 (range, 19–36) years. Indications requiring the simultaneous transplantation of livers and kidneys were primary hyperoxaluria type 1 (PH1) in 5 potential recipients and cirrhosis due to chronic hepatitis B infection and idiopathic chronic renal insufficiency in 1 potential recipient. Four recipients underwent right hepatectomy (segments 5–8) and right nephrectomy; 1 recipient underwent left hepatectomy (segments 2–4) and right nephrectomy; and 1 recipient underwent left lobectomy (segments 2–3) and right nephrectomy. There were no complications except in 1 donor (postoperative ileus). No donor developed hypertension or microalbuminuria. Conclusions With the right indications, appropriate preoperative evaluation, meticulous surgical technique, proper postoperative care, and long-term close monitoring to minimize morbidity and mortality risks, liver and kidney donation from the same donor can be considered for simultaneous kidney and liver transplantation.

Locally advanced right colon cancer may invade adjacent tissue and organs. Direct invasion of the duodenum and pancreas necessitates an en bloc resection. Previously, this challenging procedure was associated with high morbidity and mortality; however, today, this procedure can be done more safely in experienced centers. The aim of this study is to report our experience on en bloc right colectomy with pancreaticoduodenectomy for locally advanced right colon cancers. Between 2000 and 2012, 5 patients underwent en bloc multivisceral resection. No major morbidities or perioperative mortalities were observed. Median disease-free survival time was 24.5 months and median overall survival time was 42.1 (range: 4.5–70.4) months in our series. One patient lived 70 months after multivisceral resection and underwent cytoreductive surgery and total pelvic exenteration during the follow-up period. In locally advanced right colon tumors, all adhesions should be considered as malign invasion and separation should not be done. The reasonable option for this patient is to perform en bloc pancreaticoduodenectomy and right colectomy. This procedure may result in long-term survival with acceptable morbidity and mortality rates. Multidisciplinary teamwork and multimodality treatment alternatives may improve the results.

Aims Solid-pseudopapillary neoplasm (SPN) is an uncommon malignant tumor of the pancreas with a favorable prognosis unlike other pancreatic neoplasms. We investigated the clinicopathological features of 20 patients with SPN in details. Methods The patients diagnosed as SPN in Dokuz Eylul University Hospital between January 2005 and March 2016 were reviewed in terms of clinical and histopathological data. Results Mean age of the patients was 33. Three of our cases were male and 4 were children. Some patients had synchronuous malignancies. Nine patients were diagnosed by fine needle aspiration cytology (FNAC). One of our tumors had 2 × 1 mm of pancreas endocrine neoplasm in addition to SPN. One case had foci of atypical and multinucleated giant cells. All cases were positive for vimentin and CD10 antibodies and most were positive for PR and β-catenin. The mean follow-up duration was 40 mo (range 2–110 mo). Only one case showed liver metastasis. Conclusion Herein we present a series of 20 patients with 3 male and 4 pediatric cases, almost half of which were diagnosed with FNAC findings, and most of which are clinically being followed with one patient showing progression. Our series includes rare examples like collision tumor of SPN and pancreas endocrine neoplasm, SPN with multinucleated giant cells. Also cases with no surgical treatment and no progression, as well as cases with synchronous malignancies are presented. We believe that FNAC findings of any pancreatic mass should be investigated in detail for the designation of a therapy plan especially for the patients with high operation risks. The findings in our series also show that extensive necrosis, angioinvasion, perineurial invasion and larger tumor size might be predictive for worse prognosis and these patients should be more closely followed up.

Objectives: To obtain a liver prototype by using a 3 dimensional printer for preoperative evaluation of vascular structures hepatic artery, portal vein, hepatic vein based on living donor candidate’s angiographic computed tomography data in living donor liver transplantation.Materials and Methods: First, we obtained angiographic computed tomography data with a stereolithography extension of the living donor candidate. Then, we made this data suitable for the 3 dimensional printer by using a special software. We used a J750 Stratasys 3 dimensional printer to create the model.Results: In the three-dimensional model, macroscopic liver structure and vascular structures were obtained as planned hepatic artery, portal vein, hepatic vein and in accordance with angiographic computed tomography data.Conclusion: Before living donor liver transplantation, models obtained from 3 dimensional printers can be used to evaluate the anatomic structure of the donor candidate’s liver. Similarly, prior to complicated liver resections, this model can provide surgeons with a different perspective for more effective preoperative planning and assessment for safer surgery
