Abstract	Immune checkpoint therapy (ICT) has shown promising potential in the treatment of multiple solid tumors. However, the role of ICT in pancreatic ductal adenocarcinoma (PDAC) remains limited. Patterns of immune checkpoints (ICs) in PDAC represent the basis for establishing a potent ICT. The aim of this study is to create a profile of IC expression and its prognostic relevance in cancer cells of PDAC. Therefore, tumor cells from peripheral and central tissue microarray (TMA) spots from histologically confirmed PDAC of 68 patients after tumor resection were investigated in terms of expressions of TIM3, IDO, B7H4, LAG3, VISTA, and PD-L1 using immunohistochemistry. The presence of the respective ICs was compared to overall survival (OS). The presence of VISTA and PD-L1 significantly correlates with shorter OS (median OS: 22 months vs. 7 months and 22 months vs. 11 months, respectively,

Abstract	Interleukine-6 plays a key role in the progression and poor survival in pancreatic ductal adenocarcinoma (PDAC). The present study aimed to clarify if targeting the interleukin-6/glycoprotein-130 signaling cascade using the small-molecule gp130 inhibitor SC144 or raloxifene, a non-steroidal selective estrogen receptor modulator, enhances paclitaxel efficacy. MTT/BrdU assays or TUNEL staining were performed to investigate cell viability, proliferation and apoptosis induction in L3.6pl and AsPC-1 human pancreatic cell lines. In vivo, effects were studied in an orthotopic PDAC mouse model. Tumor specimens were analyzed by qPCR, immunohistochemistry and ELISA. Combination of paclitaxel/raloxifene, but not paclitaxel/SC144, enhanced proliferation and viability inhibition and increased apoptosis compared to single treatment in vitro. Synergy score calculations confirmed an additive influence of raloxifene on paclitaxel. In the PDAC mouse model, both combinations of raloxifene/paclitaxel and SC144/paclitaxel reduced tumor weight and volume compared to single-agent therapy or control. Raloxifene/paclitaxel treatment decreased survivin mRNA expression and showed tendencies of increased caspase-3 staining in primary tumors. SC144/paclitaxel reduced interleukin-6 levels in mice's tumors and plasma. In conclusion, raloxifene or SC144 can enhance the anti-tumorigenic effects of paclitaxel, suggesting that paclitaxel doses might also be reduced in combined chemotherapy to lessen paclitaxel side effects.

Abstract	Introduction: Successful R0 resection is crucial for the survival of patients with primary liver cancer (PLC) or liver metastases. Up to date, surgical resection lacks a sensitive, real-time intraoperative imaging modality to determine R0 resection. Real-time intraoperative visualization with near-infrared light fluorescence (NIRF) using indocyanine green (ICG) may have the potential to meet this demand. This study evaluates the value of ICG visualization in PLC and liver metastases surgery regarding R0 resection rates. Materials and methods: Patients with PLC or liver metastases were included in this prospective cohort study. ICG 10 mg was administered intravenously 24 h before surgery. Real-time intraoperative NIRF visualization was created with the Spectrum Results: Of the 66 included patients, median age was 65.5 years (IQR 58.7-73.9), 27 (40.9%) were female, and 18 (27.3%) were operated on laparoscopically. Additional ICG-positive lesions were detected in 23 (35.4%) patients, of which 9 (29%) were malignant. In patients with no fluorescent signal at the resection margin, R0 rate was 93.9%, R1 rate was 6.1%, and R2 rate was 0% compared to an ICG-positive resection margin with an R0 rate of 64.3%, R1 rate of 21.4%, and R2 rate of 14.3% ( Conclusion: The presented study provides significant evidence that ICG NIRF guidance helps to identify R0 resection intraoperatively. This offers true potential to verify radical resection and improve patient outcomes. Furthermore, implementation of NIRF-guided imaging in liver tumor surgery allows us to detect a considerable amount of additional malignant lesions.

Abstract	Muscarinic acetylcholine receptor M3 (M3R) has repeatedly been shown to be prominently expressed in human colorectal cancer (CRC), playing roles in proliferation and cell invasion. Its therapeutic targetability has been suggested in vitro and in animal models. We aimed to investigate the clinical role of MR3 expression in CRC for human survival. Surgical tissue samples from 754 CRC patients were analyzed for high or low immunohistochemical M3R expression on a clinically annotated tissue microarray (TMA). Immunohistochemical analysis was performed for established immune cell markers (CD8, TIA-1, FOXP3, IL 17, CD16 and OX 40). We used Kaplan-Meier curves to evaluate patients' survival and multivariate Cox regression analysis to evaluate prognostic significance. High M3R expression was associated with increased survival in multivariate (hazard ratio (HR) = 0.52; 95% CI = 0.35-0.78;

Abstract	Purpose: With the onset of the COVID pandemic in Germany in March 2020, far-reaching restrictions were imposed that limited medical access for patients. Screening examinations such as colonoscopies were greatly reduced in number. As rapid surgical triage after diagnosis is prognostic, our hypothesis was that pandemic-related delays would increase the proportion of advanced colon cancers with an overall sicker patient population. Methods: A total of 204 patients with initial diagnosis of colon cancer were analyzed in this retrospective single-center study between 03/01/2018 and 03/01/2022. Control group (111 patients, pre-COVID-19) and the study group (93 patients, during COVID-19) were compared in terms of tumor stages, surgical therapy, complications, and delays in the clinical setting. The data were presented either as absolute numbers or as median for constant data. Results: A trend towards more advanced tumor stages (T4a p = 0.067) and a significant increase of emergency surgeries (p = 0.016) with higher rates of ileus and perforation (p = 0.004) as well as discontinuity resections (p = 0.049) during the pandemic could be observed. Delays in surgical triage after endoscopic diagnosis were seen during the 2nd lockdown (02/11/20-26/12/20; p = 0.031). Conclusion: In summary, the results suggest delayed treatment during the COVID-19 pandemic, with the infection pattern of COVID appearing to have a major impact on the time between endoscopic diagnosis and surgical triage/surgery. Adequate care of colon cancer patients is possible even during a pandemic, but it is important to focus on structured screening and tight diagnosis to treatment schedules in order to prevent secondary pandemic victims.

Title translation	Effectiveness of Mucosal Advancement Flaps in Surgery of Perianal Fistulas from Crohn´s Disease and Cryptoglandular Fistulas - a Long-term Follow-up Study.
Abstract	Aim: Surgical treatment of perianal fistulae originating from Crohn's Disease (CD) or cryptoglandular abscess (CGA) remains a challenge. Data on long-term healing rates are scarce. We aimed to evaluate the long-term success rate of mucosal advancement flap (MAF) operations. Methods: This single centre retrospective analysis was performed at a tertiary referral centre (Charité University Hospital Berlin, Campus Benjamin Franklin) between March 1, 2010 and March 31, 2020. Patients with complex perianal fistulae originating from CD or CGA treated with MAF were included. Long-time healing rates of MAF in CGA and CD were compared. Regression analysis was used to identify predictive factors for definitive healing. Results: 83 patients (24 CD, 59 CGA,) were included. Median follow-up for CD was 5.4 and 1.9 years for CGA. Definitive healing of fistulae was achieved in 19 (79.2%) CD patients (p = 0.682) and in 44 (74.6%) CGA patients. Healing time was significantly shorter in CGA than in CD (9.3 months [standard deviation: SD= 11.3 months] vs. 30.9 months [SD = 23.5 months]; p < 0.001). Treatment with biologicals (hazard ratio: HR = 0.18, 95%-confidence interval: 95%-CI = 0.06-0.59, p = 0.004) and diverting ileostomy (HR = 0.29, 95%-CI = 0.10-0.85, p = 0.023) in CD were independent predictors for MAF success. Simultaneous medication with azathioprine in CD was an independent predictor for MAF failure (HR = 3.20, 95%-CI = 1.05-9.81, p = 0.041). Conclusion: This study demonstrates that surgical therapy of perianal fistulae with MAF is successful in about 75% of patients overall. Patients with MC benefit from biologicals and a diverting ileostomy. Treatment with azathioprine had a negative impact on recurrence rates. Repeated MAF operations did not increase the risk of failure in subsequent operations.

Abstract	Background: Approximately 15% of patients experience post-hepatectomy liver failure after major hepatectomy. Poor hepatocyte uptake of gadoxetate disodium, a magnetic resonance imaging contrast agent, may be a predictor of post-hepatectomy liver failure. Methods: A retrospective cohort study of patients undergoing major hepatectomy (≥3 segments) with a preoperative gadoxetate disodium-enhanced magnetic resonance imaging was conducted. The liver signal intensity (standardized to the spleen) and the functional liver remnant was calculated to determine if this can predict post-hepatectomy liver failure after major hepatectomy. Results: In 134 patients, low signal intensity of the remnant liver standardized by signal intensity of the spleen in post-contrast images was associated with post-hepatectomy liver failure in multiple logistic regression analysis (Odds Ratio 0.112; 95% CI 0.023-0.551). In a subgroup of 33 patients with lower quartile of functional liver remnant, area under the curve analysis demonstrated a diagnostic accuracy of functional liver remnant to predict post-hepatectomy liver failure of 0.857 with a cut-off value for functional liver remnant of 1.4985 with 80.0% sensitivity and 89.3% specificity. Conclusion: Functional liver remnant determined by gadoxetate disodium-enhanced magnetic resonance imaging is a predictor of post-hepatectomy liver failure which may help identify patients for resection, reducing morbidity and mortality.

Abstract	Background: Proctocolectomy with ileal pouch-anal anastomosis is the standard surgical procedure for ulcerative colitis refractory to medical treatment. In a few cases, ileal pouch-anal anastomosis cannot be completed due to intraoperative technical problems. The aim of this single-center study was to identify risk factors for a technically failed ileal pouch-anal anastomosis. Methods: In total, 391 patients with ulcerative colitis who received ileal pouch-anal anastomosis were identified. Clinical and perioperative data from patients with successful ileal pouch-anal anastomosis (IPAA+) were compared to data from failed ileal pouch-anal anastomosis (IPAA-). Definition of failed ileal pouch-anal anastomosis was intraoperative failure to perform ileal pouch-anal anastomosis. Risk factors for failed ileal pouch-anal anastomosis were assessed by logistic regression. Cut-off values were calculated on the basis of receiver operating characteristic curves and the Youden Index. Results: The rate of failed ileal pouch-anal anastomosis was 26 of 391 (6.6%). In 22 of 26 cases (84.6%), there was an insufficient length of the small intestinal mesentery. Patients with failed ileal pouch-anal anastomosis were more often male (80.8% vs 54.5%, P = .009), older (47.1 ± 14.1 vs 39.2 ± 12.8 years, P = .007), had a higher body mass index 27.2 ± 4.5 vs 23.7 ± 4.3 kg/m Conclusion: Technical failure of ileal pouch-anal anastomosis is elevated in patients with higher body mass index, with refractory ulcerative colitis, and/or extended immunosuppressive medication. Three-staged ileal pouch-anal anastomosis and optimizing preoperative conditions may help to elevate the rate of successful ileoanal pouch construction in these patients.

Abstract	Background: An anastomotic leak (AL) after a restorative proctocolectomy and an ileal J-pouch increases morbidity and the risk of pouch failure. Thus, a perfusion assessment during J-pouch formation is crucial. While indocyanine green near-infrared fluorescence (ICG-NIRF) has shown potential to reduce ALs, its suitability in a restorative proctocolectomy remains unclear. We aimed to develop a standardized approach for investigating ICG-NIRF and ALs in pouch surgery. Methods: Patients undergoing a restorative proctocolectomy with an ileal J-pouch for ulcerative colitis at an IBD-referral-center were included in a prospective study in which an AL within 30 postoperative days was the primary outcome. Intraoperatively, standardized perfusion visualization with ICG-NIRF was performed and video recorded for postoperative analysis at three time points. Quantitative clinical and technical variables (secondary outcome) were correlated with the primary outcome by descriptive analysis and logistic regression. A novel definition and grading of AL of the J-pouch was applied. A postoperative pouchoscopy was routinely performed to screen for AL. Results: Intraoperative ICG-NIRF-visualization and its postoperative visual analysis in 25 patients did not indicate an AL. The anastomotic site after pouch formation appeared completely fluorescent with a strong fluorescence signal (category 2) in all cases of ALs (4 of 25). Anastomotic site was not changed. ICG-NIRF visualization was reproducible and standardized. Logistic regression identified a two-stage approach vs. a three-stage approach (Odds ratio (OR) = 20.00, 95% confidence interval [CI] = 1.37-580.18, Conclusion: We present a standardized, comparable approach of ICG-NIRF visualization in pouch surgery. Our data indicate that the visual interpretation of ICG-NIRF alone may not detect ALs of the pouch in all cases-quantifiable, objective methods of interpretation may be required in the future.

Abstract	Background: Inflammation of the rectal remnant may affect the postoperative outcome of ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). We aimed to determine the extent of inflammation in the anastomotic area during IPAA and to investigate the impact of proctitis on postoperative complications and long-term outcomes. Methods: Three hundred thirty-four UC patients with primary IPAA were included in this retrospective case-control study. The histopathologic degree of inflammation in the anastomotic area was graded into three stages of no proctitis ("NOP"), mild to medium proctitis ("MIP"), and severe proctitis ("SEP"). Preoperative risk factors, 30-day morbidity, and follow-up data were assessed. Kaplan-Meier analysis was performed in the event of pouch failure. Results: The prevalence of proctitis was high (MIP 40.4%, and SEP 42.8%). During follow-up, the incidence of complications was highest among SEP: resulting in re-intervention (n = 40; 28.2%, p = 0.017), pouchitis (n = 36; 25.2%, p < 0.01), and pouch failure (n = 32; 22.4%, p = 0.032). The time interval to pouch failure was 5.0 (4.0-6.9) years among NOP, and 1.2 (0.5-2.3) years in SEP (p = 0.036). ASA 3, pouchitis, and pouch fistula were independent risk factors for pouch failure. Conclusion: Proctitis at the time of IPAA is common. A high degree of inflammation is associated with poor long-term outcomes, an effect that declines over time. In addition, a higher degree of proctitis leads to earlier pouch failure.
