    Abstract: The safety of synthetic mesh in elective hernia repair in the setting of immunosuppression lacks national and international consensus. The aim of our analysis was to explore the effects of immunosuppression on the rates of wound complications. Methods Comparative analysis of immunocompetent and immunocompromised patients with elective mesh repair of inguinal, femoral, primary ventral, incisional or parastomal hernia between January 2001 and December 2013. Immunosuppression included glucocorticoids, biologicals, chemotherapy and chemoradiotherapy. Primary outcome parameter was mesh infection rate. Follow‐up questionnaires were completed in written form or by telephone interview. Results Questionnaire response rate was 59.5% ( n = 194) with a median follow‐up of 33 (interquartile range: 28–41) months. There were no differences between immunocompromised ( n = 40, 20.6%) and immunocompetent patients ( n = 154, 79.4%) based on hernia and patient characteristics. Immunosuppression was not associated with the rates of mesh infection ( P = 1.000), surgical site infection (SSI, P = 0.330) or re‐operation for SSI ( P = 0.365), but with higher rates ( P = 0.007) and larger odds for hernia recurrence (odds ratio 3.264, 95% confidence interval 1.304–8.172; P = 0.012). Mesh infection also increased the odds for hernia recurrence (odds ratio 11.625; 95% confidence interval 1.754–77.057; P = 0.011). Only in the subset of ventral/incisional hernias, immunocompromised ( n = 8, 40%) patients had higher recurrence rates than immunocompetent patients ( n = 5, 11.6%; P = 0.017). Patients with SSI reported more frequently moderate to severe dysesthesia at the surgical site ( P = 0.013) and would less frequently re‐consent to surgery ( P = 0.006). Conclusion Immunosuppression does not increase the rate of wound infections after elective hernia repair with synthetic mesh. However, immunosuppression and mesh infection are risk factors for hernia recurrence.

    Abstract: Background: Ileostomy is often required in patients undergoing bowel resections for inflammatory bowel diseases (IBD), colorectal cancer, and emergencies. Unfortunately, some patients develop a high-output stoma (HOS). This condition affects homeostasis and may be life threatening. We aimed to identify possible risk factors for the development of HOS. Patients and methods: From 2012 to 2018, 296 patients who underwent ileostomy at Charité – Universitätsmedizin Berlin, Campus Benjamin Franklin were retrospectively analyzed. Emergency operations were included. Diverting ileostomy, end ileostomies and anastomotic stomata with at least part ileum, were examined. HOS was defined as stoma output of more than 1,000 mL per day for more than 3 days. Univariate and multivariable analyses were used to detect potential risk factors for the development of HOS. Results: 41 of 296 patients developed HOS (13.9%). Mortality was 0.3%. In the univariate analysis, age ( p & lt; 0.002), diagnosis (Crohn's disease, p = 0.005), arterial hypertension ( p = 0.023), surgical procedure (right-sided colectomy, small bowel resection, p & lt; 0.001), open technique ( p & lt; 0.002), emergencies ( p = 0.014), and anastomotic ileostomy ( p & lt; 0.001) were identified as risk factors. In the multivariable logistic regression, older age, diagnosis (Crohn's disease) and surgical procedure (right-sided colectomy, separate ileostomy, small bowel resection) remained significant risk factors. Conclusion: The occurrence of HOS is a relevant problem after ileostomy. The identification of risk factors for a high-output may be helpful for monitoring, early diagnosis and initiation of therapy as well as in the planning of close follow-up care.

    Abstract: In patients on oral antiplatelet therapy secondary to critical vascular diseases, the risk of interrupting antiplatelet therapy has to be weighed against the risk of postoperative hematoma or bleeding when surgery is planned. The goal of this study was to determine the risk of postoperative hematoma and postoperative bleeding in elective inguinal hernia surgery during continuous platelet inhibition. Patients receiving either elective total extraperitoneal hernioplasty or Lichtenstein repair for inguinal hernia were included. Patients with mere suture repair, emergency hernia repair, combination of different simultaneous operations, and patients under therapeutic anticoagulation with heparin were excluded. Postoperative bleeding/hematoma was determined by physical examination and graded according to the Clavien-Dindo classification. Between January 2006 and December 2013, 561 patients with elective surgical repair of an inguinal hernia were included. A total of 29 patients were under continuous perioperative platelet inhibition (PI) with either aspirin or clopidogrel in addition to perioperative antithrombotic prophylaxis with subcutaneous dalteparin injections (PI group). A total of 532 patients received perioperative antithrombotic prophylaxis only (control group). The number of patients under antiplatelet therapy increased from 1.3% (Jan. 2006–Dec. 2009) to 10.0% (Jan. 2010–Dec. 2013; P & lt; 0.0001). Postoperative hematoma/bleeding occurred in 5 PI patients (17.2%) versus 38 control patients (7.1%, P = 0.062). Rate of postoperative bleeding or hematoma is not higher under mono antiplatelet therapy for elective inguinal hernia repair. Since the majority of hematomas can be treated conservatively, it seems unnecessary to stop mono platelet inhibition perioperatively.

    Abstract: Prolonged postoperative ileus (PPOI) is common after bowel resections, especially in Crohn’s disease (CD). The pathophysiology of PPOI is not fully understood. PPOI could affect only the upper or lower gastrointestinal (GI) tract. The aim of this study was to assess risk factors for diverse types of PPOI, particularly to differentiate PPOI of upper and lower GI tract. Methods A retrospective analysis of 163 patients with CD undergoing ileocecal resection from 2015 to 2020 in a single center was performed. PPOI of the upper GI tract was predefined as the presence of vomiting or use of nasogastric tube longer than the third postoperative day. Lower PPOI was predefined as the absence of defecation for more than three days. Independent risk factors were identified by multivariable logistic regression analysis. Results Overall incidence of PPOI was 42.7%. PPOI of the upper GI tract was observed in 30.7% and lower PPOI in 20.9% of patients. Independent risk factors for upper PPOI included older age, surgery by a resident surgeon, hand-sewn anastomosis, prolonged opioid analgesia, and reoperation, while for lower PPOI included BMI ≤ 25 kg/m 2 , preoperative anemia, and absence of ileostomy. Conclusion This study identified different risk factors for upper and lower PPOI after ileocecal resection in patients with CD. A differentiated upper/lower type approach should be considered in future research and clinical practice. High-risk patients for each type of PPOI should be closely monitored, and modifiable risk factors, such as preoperative anemia and opioids, should be avoided if possible.

    Abstract: The German Classification of Diverticular Disease was introduced a few years ago. The aim of this study was to determine whether Classification of Diverticular Disease enables an exact stratification of different types of diverticular disease in terms of course and treatment. Methods This was a prospective, bicentric observational trial. Patients aged ≥ 18 years with diverticular disease were prospectively included. The primary endpoint was the rate of recurrence within 2 year follow-up. Secondary outcome measures were Gastrointestinal Quality of Life Index, Quality of life measured by SF-36, frequency of gastrointestinal complaints, and postoperative complications. Results A total of 172 patients were included. After conservative management, 40% of patients required surgery for recurrence in type 1b vs. 80% in type 2a/b ( p = 0.04). Sixty percent of patients with type 2a (micro-abscess) were in need of surgery for recurrence vs. 100% of patients with type 2b (macro-abscess) ( p = 0.11). Patients with type 2a reached 123 ± 15 points in the Gastrointestinal Quality of Life Index compared with 111 ± 14 in type 2b ( p = 0.05) and higher scores in the “Mental Component Summary” scale of SF-36 (52 ± 10 vs. 43 ± 13; p = 0.04). Patients with recurrent diverticulitis without complications (type 3b) had less often painful constipation (30% vs. 73%; p = 0.006) when they were operated compared with conservative treatment. Conclusion Differentiation into type 2a and 2b based on abscess size seems reasonable as patients with type 2b required surgery while patients with type 2a may be treated conservatively. Sigmoid colectomy in patients with type 3b seems to have gastrointestinal complaints during long-term follow-up. Trial registration https://www.drks.de ID: DRKS00005576

    Abstract: Standardization and digitalization are getting more and more essential in surgery. Surgical procedure manager (SPM®) is a freestanding computer serving as a digital supporter in the operating room. SPM® navigates step-by-step through surgery by providing a checklist for each individual step. Methods This was a single center, retrospective study at the Department for General and Visceral Surgery at Charité—Universitätsmedizin Berlin, Campus Benjamin Franklin. Patients who underwent ileostomy reversal without SPM® in the period of January 2017 until December 2017 were compared to patients who were operated with SPM® in the period of June 2018 until July 2020. Explorative analysis and multiple logistic regression were performed. Results Overall, 214 patients underwent ileostomy reversal: 95 patients without SPM® vs. 119 patients with SPM®. Ileostomy reversal was performed by head of department/attendings in 34.1%, by fellows in 28.5% and by residents in 37.4%; p  = 0.91. Postoperative intraabdominal abscess emerged more often in patients without SPM®: ten (10.5%) patients vs. four (3.4%) patients; p  = 0.035. Multiple logistic regression showed a risk reduction for intraabdominal abscess {Odds ratio (OR) 0.19 [95% confidence interval (CI) 0.05–0.71]; p  = 0.014} and for bowel perforation [OR 0.09 (95% CI 0.01–0.93); p  = 0.043] in the group with use of SPM® in ileostomy reversal. Conclusions SPM® may reduce postoperative complications in ileostomy reversal such as intraabdominal abscess and bowel perforation. SPM® may contribute to patient safety.

    Abstract: Myopenia and myosteatosis have been proposed to be prognostic factors of surgical outcomes for various diseases, but their exact role in Crohn’s disease (CD) is unknown. The aim of this study is to evaluate their impact on anastomotic leakage, CD recurrence, and postoperative complications after ileocecal resection in patients with CD. Methods A retrospective analysis of CD patients undergoing ileocecal resection at our tertiary referral center was performed. To assess myopenia, skeletal muscle index (skeletal muscle area normalized for body height) was measured using an established image analysis method at third lumbar vertebra level on MRI cross-sectional images. Muscle signal intensity was measured to assess myosteatosis index. Results A total of 347 patients were retrospectively analyzed. An adequate abdominal MRI scan within 12 months prior to surgery was available for 223 patients with median follow-up time of 48.8 months (IQR: 20.0–82.9). Anastomotic leakage rate was not associated with myopenia (SMI: p  = 0.363) or myosteatosis index ( p  = 0.821). Patients with Crohn’s recurrence had a significantly lower SMI ( p  = 0.047) in univariable analysis, but SMI was not an independent factor for recurrent anastomotic stenosis in multivariable analysis (OR 0.951, 95% CI 0.840–1.078; p  = 0.434). Postoperative complications were not associated with myopenia or myosteatosis. Conclusion Based on the largest cohort of its kind with a long follow-up time, we could provide some data that MRI parameters for myopenia and myosteatosis may not be reliable predictors of postoperative outcome or recurrence in patients with Crohn’s disease undergoing ileocecal resection.
