Purpose: Gallstone formation is increased after gastric (GR) or esophageal resection (ER); however, the exact pathophysiology is not fully understood yet. Symptomatic cholecystolithiasis and the need for subsequent cholecystectomy after upper gastrointestinal resection can alter the outcome in oncological patients. There is an ongoing discussion if these patients benefit from a simultaneous prophylactic cholecystectomy. This study aims to analyze the risk of gallstone formation after GR or ER and the perioperative course of a subsequent cholecystectomy. Methods: In this study, all patients were included, who underwent an oncological gastric or esophageal resection at the Medical University of Innsbruck, Department of Visceral, Transplant and Thoracic Surgery in the years 2003–2021. Results: A simultaneous cholecystectomy was performed in 29.8% with GR and in 2.1% with ER (p < 0.001). There was no significant difference in complications or length-of-stay between patients with simultaneous vs. no simultaneous cholecystectomy. Newly developed gallstones tended to be more common after GR (16% vs. 10% ER), after reconstruction without preservation of the duodenal passage (17% vs. 11% with) and after GR with lymph node dissection (19% vs. 5% without). After ER, subsequent cholecystectomy was significant less frequently (11.4% vs. 2.9% OR) (p = 0.005). The subsequent cholecystectomy was performed openly in 57.1% with major complications classified as Clavien-Dindo ≥ 3a in 14.3%. Conclusion: Based on the findings of our study, we do not recommend simultaneous cholecystectomy routinely in oncological gastric or esophageal resections. An individualized approach depending on risk factors like extensive lymphadenectomy or duodenal passage can be discussed. [ABSTRACT FROM AUTHOR]

Purpose: Patients with colon cancer are usually included in an intensive 5-year surveillance protocol after curative resection, independent of the tumor stage, though early stages have a considerably lower risk of recurrence. The aim of this study was to analyze the adherence to an intensive follow-up and the risk of recurrence in patients with colon cancer in UICC stages I and II. Methods: In this retrospective study, we assessed patients who underwent resection for colon cancer in UICC stages I and II between 2007 and 2016. Data were collected on demographics, tumor stages, therapy, surveillance, recurrent disease, and oncological outcome. Results: Of the 232 included patients, 43.5% (n = 101) reached the 5-year follow-up disease-free. Seven (7.5%) patients in stage UICC I and sixteen (11.5%) in UICC II had a recurrence, with the highest risk in patients with pT4 (26.3%). A metachronous colon cancer was detected in four patients (1.7%). The therapy of recurrence was intended to be curative in 57.1% (n = 4) of UICC stage I and in 43.8% (n = 7) of UICC stage II, but only in one of seven patients over 80 years. 44.8% (n = 104) of the patients were lost to follow-up. Conclusion: A postoperative surveillance in patients with colon cancer is important and recommended as a recurrent disease can be treated successfully in many patients. However, we suggest that a less intensive surveillance protocol is reasonable for patients with colon cancer in early tumor stages, especially in UICC stage I, as the risk of recurrent disease is low. With elderly and/or frail patients in a reduced general condition, who will not endure further specific therapy in case of a recurrence, the performance of the surveillance should be discussed: we recommend a significant reduction or even renunciation.

Purpose: This study analyzed the prevalence and factors influencing the history of chronic anastomotic leakage following low anterior resection for rectal cancer. Furthermore, the treatment of a persisting presacral sinus and the impact of stoma reversal on outcome were evaluated. Methods: The institutional database was scanned for all patients with anastomotic leakage, who were primarily treated for low rectal cancer between January 1995 and December 2019. Patients with rectovaginal and rectovesical fistula or an inadequate follow-up were excluded (n = 5). After applying the exclusion criteria, 71 patients remained for analysis. Results: A total of 39 patients out of 71 patients with anastomotic leakage (54.9%) developed a persisting presacral sinus. Neoadjuvant radiochemotherapy or chemotherapy showed a significant impact on the formation of a chronic anastomotic leakage (radiochemotherapy: p = 0.034; chemotherapy: p = 0.050), while initial surgical treatment showed no difference for anastomotic healing (p = 0.502), but a significantly better overall survival (p = 0.042). Multiple therapies and surgical revision had a negative impact on patients' rate of natural bowel continuity (p = 0.006/ < 0.001). In addition, the stoma reversal cohort showed improved overall 10-year survival (p = 0.004) and functional results (bowel continuity: p = 0.026; pain: p = 0.031). Conclusion: Primary surgical therapy for chronic anastomotic leakage should consist of surgical treatment. Furthermore, the reversal of a protective stoma should be considered a viable option in treating chronic presacral sinus to improve pain symptoms and bowel continuity. [ABSTRACT FROM AUTHOR]

Background: The closure of a stoma site has a high incidence of incisional hernia (IH) development, reaching 30% in some studies. Location and defect size in the abdominal wall depend on the type of stoma formed, most commonly a loop ileostomy or terminal sigmoid colostomy. Methods: The retrospective single-centre study includes all consecutive patients who underwent stoma reversal between 2010 and 2016 at the Department of Visceral, Transplant and Thoracic Surgery in Innsbruck. Patient characteristics and follow-up examinations were evaluated for IH at both the stoma reversal site and at any other surgical access sites. Results: A total of 181 patients (49% female, 51% male) had a stoma reversal operation. A parastomal hernia was present in 5% (n = 9). Follow-up data was available for 140 patients (77%). A postoperative IH at the stoma reversal site developed in 15.7% (n = 22) and in 18.6% (n = 26) at other surgical wounds to the abdominal wall during a median follow-up of 136 weeks. The combination of a preoperative parastomal hernia and a postoperative IH was observed in 2.8% (n = 5). Parastomal herniation, male sex, body mass index over 25, arterial hypertension and concomitant ventral hernia were associated with IH formation at the stoma reversal. Conclusion: The rate of IH at the stoma reversal site was lower than expected from the literature, whereas the rate of IH at other surgical wounds to the abdominal wall was within the expected range.

Purpose: Resection of a long rectal stump after previous colectomy or Hartmann procedure often requires a combined transperitoneal and transperineal approach because of limited access through a perineal incision alone. Risks associated with this procedure include iatrogenic injury to bowels, nerves, ureters, vessels and sexual organs. This study reports on the feasibility and safety of perianal minimally invasive surgery (PAMIS) for the resection of long rectal stumps that would otherwise require a combined transperitoneal and perianal approach.Methods: PAMIS utilizes standard laparoscopic equipment and a single access port to dissect the rectal stump following the mesorectal fascia into the pelvis after excision of the anal canal. Three PAMIS procedures were performed between February and April 2016. Feasibility, safety and outcome were analysed.Results: Three patients with previous colectomy and ostomy creation due to colitis ulcerosa (n = 2) and idiopathic enteropathy (n = 1) underwent PAMIS. The rectal stump length ranged between 10 and 19 cm. The median postoperative length of stay was 9 (range 6 to 11) days and the median operating time was 90 (range 80 to 120) min. There were no perioperative complications.Conclusion: PAMIS is a feasible, safe and efficient procedure for rectal stump resection avoiding the transperitoneal approach for pelvic dissection.

Purpose: The aim of this study was to analyse the long-term outcome of rectal cancer patients who submitted to preoperative chemoradiation with consecutive intensive follow-up and aggressive surgical treatment of recurrent disease. Methods: Patients with locally advanced (cT3-4 Nx M0-1) mid/low rectal cancer were treated at a tertiary university hospital with preoperative long-course chemoradiation followed by resection (according to a prospective study protocol). After resection, all patients were urged to participate in a standardised, risk-independent intensive follow-up program. All curatively treated patients ( n = 153, 96 %) were included in our long-term analysis with respect to curative re-resection of recurrent disease. Results: Of 153 patients, 143 (93 %) participated in our follow-up program: 63 % were surveyed longer than 5 years after primary therapy (mean follow-up 75 months, 95 % CI 67.8-82.2). Fifty-five (36 %) patients developed cancer recurrence (mean 27.8 months, 95 % CI 20.6-34.9, range 3-108), giving a disease-free survival rate of 68.5 and 60.7 % at 5 and 10 years; 21 (38 %) patients were re-resected curatively and 58 (38 %) patients died during the observation period, giving an overall survival rate of 70.8 and 57.5 % at 5 and 10 years. Multivariate analysis found tumour differentiation ( P < 0.01), operative procedure ( P < 0.05) and downstaging ( P < 0.01) to be independent variables influencing overall survival. Conclusions: The combination of multimodal therapy and aggressive surgical treatment of metastases including repeated re-resections in curative intention is relevant in order to chronify the disease. Thus, both intensive and extended follow-up beyond 5 years appear to be mandatory. [ABSTRACT FROM AUTHOR]

Abdominal soft tissue sarcomas (ASTS) represent a rare malignancy of the abdomen. Diagnosis is often delayed because ASTS tend to be asymptomatic for a long time. Typical clinical symptoms such as pain and augmentation of the abdominal girth develop as a result of the compressing and displacing rather than infiltrating growth pattern of large ASTS. Treatment of patients with ASTS should be managed interdisciplinarily in a tumourboard. Surgery (i.e. wide excision with negative margins) represents the only potentially curative treatment option. Multimodal treatment with radiotherapy and/or chemotherapy, however, is indispensable to reduce the rather high local recurrence rate in these patients despite complete resection. A preoperative core needle biopsy is recommended if diagnosis and hence also therapy are unclear: the biopsy pathway should be chosen in accordance with the surgeon, and the excision has to be performed afterwards within primary surgery. The aggressiveness of surgery is still under debate and ranges from a tissue/organ-sparing approach to an extensive approach with compartmental resection. Thus, the oncologic surgeon must be able to handle complex multivisceral resection as well as extensive vascular reconstruction. Surgery for local recurrence has been shown to be feasible, and the presence of distant metastases usually represents a contraindication for surgery. [ABSTRACT FROM AUTHOR]

Background: Surgical treatment of colorectal cancer (CRC) should be aimed primarily at achieving a combination of surgical-oncologic radicalness and the highest possible quality of life. In recent years, surgical therapy for T1 CRC has tended toward less radical interventions. The question regarding changes in survival and recurrence rates still is unanswered. Methods: A retrospective medical chart review of patients surgically treated in our department for T1 CRC from January 1990 to December 2010 ( n = 223) was performed. Charts were reviewed for tumor-specific parameters, local recurrence, distant metastasis, and patient survival. The different treatment options used were strictly separated for a more detailed workup. Results: Radical resection (RR) was performed for 57.1 %, local resection (LR) for 14.8 %, and an endoscopic approach (EA) for 28.1 % of the study population. After receipt of the histology report, 35.7 % of the patients initially resected nonradically underwent reoperation, mostly using RR. Seven patients experienced a local recurrence over time (3.6 %): one after initial RR, three after LR, and three after EA. Systemic recurrence occurred for nine patients (4.6 %) over time, six of whom had undergone initial RR. High-risk criteria were shown for 20 T1 CRCs. For 60 % (12/20) of the patients, initial RR was performed. Radical reoperation was performed for 75 % of the nonradically treated high-risk tumors. One high-risk patient without reoperation experienced metastatic disease over time. The 5-year overall survival rate was 87.2 %, itemized for the defined subgroups as follows: 83.9 % for RR, 82.8 % for LR, and 58.2 % for EA. Conclusion: Patients with T1 CRC had a distinctly higher incidence of local recurrence after EA or LR. Explicit workup in terms of risk classification is crucial to reducing the risk of local and systemic recurrence. A nonradical approach should be only a second option for patients with T1 CRC, namely, those solely in clearly low-risk situations or those with distinct comorbidities. [ABSTRACT FROM AUTHOR]

Perforated diverticulitis with advanced generalized peritonitis is a life-threatening condition requiring emergency operation. To reduce the rate of colostomy formation, a new treatment algorithm with damage control operation, lavage, limited closure of perforation, abdominal vacuum-assisted closure (VAC; V.A.C.®), and second look to restore intestinal continuity was developed. This algorithm allowed for three surgical procedures: primary anastomosis ± VAC in stable patients (group I), but damage control with lavage, limited resection of the diseased colonic segment, VAC and second-look operation with delayed anastomosis in patients with advanced peritonitis or septic shock (group II), and Hartmann procedure was done for social reasons in stable patients (group III) All 27 consecutive patients (16 women; median age 68 years) requiring emergency laparotomy for perforated diverticulitis (Hinchey III/IV) between October 2006 and September 2008 were prospectively enrolled in the study. No major complications were observed in group I ( n = 6). Nine patients in group II ( n = 15) had intestinal continuity restored during a second-look operation, of whom one patient developed anastomotic leakage. The median length of stay at intensive care unit was 5 days. Considering an overall mortality rate of 26% ( n = 7), the rate of anastomosis in surviving patients was 70%. Damage control with lavage, limited bowel resection, VAC, and scheduled second-look operation represents a feasible strategy in patients with perforated diverticulitis (Hinchey III and IV) to enhance sepsis control and improve rate of anastomosis.

Colorectal cancer is one of the leading causes of cancer death. We analyzed the value of standardized, risk-independent postoperative surveillance. Between 1995 and 2001, 564 patients with colorectal cancer underwent standardized oncologic resection. One hundred thirty-four were unable to take part in the surveillance program, while 430 patients were grouped as follows: group I ( n=272, risk-independent follow-up), group II ( n=113, follow-up at other departments), and group III ( n=45, no follow-up). The 5-year cancer-specific survival rate for UICC III and IV was significantly higher in group I (87%) as compared to group II (35%). In group I, the 5-year disease-free survival rate was 70%. Cancer recurrence occurred at mean 17 (±12) months after colorectal resection and yielded a 5-year survival rate of 63%. Reresection was performed in 17 (35%) patients, of whom ten remained disease-free (5-year survival rate, 91%). The money spent for one patient’s 5-year follow-up was 1665. A standardized, risk-independent follow-up program allows early diagnosis of asymptomatic recurrence of colorectal cancer. Reresection improves the 5-year survival rate in this setting.
