Abstract
BACKGROUND Guidelines on Crohn's perianal fistulas recommend anti-tumour necrosis factor (TNF) treatment and suggest considering surgical closure for patients with surgically amenable disease. However, long-term outcomes following these two strategies have not been directly compared. The aim of this study was to assess radiological healing in patients who received short-term anti-TNF treatment and surgical closure compared with those who received anti-TNF treatment alone. METHODS The PISA-II trial was a multicentre, patient preference study done in nine hospitals in the Netherlands and one hospital in Italy. Adult patients with Crohn's disease and an active high perianal fistula with a single internal opening were eligible for inclusion. After counselling, patients with no treatment preference were randomly assigned (1:1) using random block randomisation (block sizes of six without statification), to 4-month anti-TNF therapy and surgical closure or anti-TNF therapy for 1 year, after seton insertion. Patients with a treatment preference received their preferred therapy. The primary outcome was radiological healing assessed by MRI at 18 months, defined as a complete fibrotic tract or a MAGNIFI-CD (Magnetic Resonance Index for Fistula Imaging in Crohn's Disease) score of 0, assessed according to the intention-to-treat principle. Secondary outcomes included clinical closure, number of patients undergoing surgical reintervention and number of reinterventions, recurrences, and impact on quality of life measured by the Perianal Disease Activity Index (PDAI). Analyses were performed on an intention-to-treat basis and additionally an as-treated analysis for radiological healing and clinical closure. This study was registered at the Dutch Trial Registry, NL7625, and with EudraCT, 2018-002064-15, and is closed to accrual due to completion. FINDINGS Between Sept 14, 2013, and Dec 7, 2019, 94 patients were enrolled onto the trial, of whom 32 (34%) were randomly assigned and 62 (66%) chose a specific treatment. 38 (40%) patients were assigned to the surgical closure group and 56 (60%) patients to the anti-TNF group. At 18 months, radiological healing was significantly more common in the surgical closure group (12 [32%] patients) than in the anti-TNF group (five [9%] patients; p=0·005). By contrast, clinical closure was not significantly different between the two treatment groups (26 [68%] patients in the surgical closure group vs 29 [52%] patients in the anti-TNF group; p=0·076). Significantly fewer patients required a reintervention in the surgical closure group than in the anti-TNF therapy group (five [13%] patients in the surgical closure group, median one reintervention [IQR one to three] vs 24 [43%] patients in the anti-TNF group, median two reinterventions [one to two]; p=0·005). Among patients who reached clinical closure during follow-up, four (14%) of 29 in the surgical closure group and five (16%) of 31 in the anti-TNF therapy group had a recurrence, which occurred only in patients without radiological healing. PDAI was significantly lower in the surgical closure group than in the anti-TNF group after 18 months (p=0·031). Adverse events and serious adverse events were similar in both treatment groups and mostly entailed reinterventions. Ten (11%) patients had side-effects associated with anti-TNF treatment. Two serious adverse events unrelated to study treatment occurred (appendicitis and myocardial infarction). One patient died from a tongue base carcinoma, unrelated to study treatment. INTERPRETATION Short-term anti-TNF treatment combined with surgical closure induces long-term MRI healing more frequently than anti-TNF therapy in patients with Crohn's perianal fistulas. These data suggest that patients with Crohn's perianal fistula amenable for surgical closure should be counselled for this therapeutic approach.

Abstract
BACKGROUND It was hypothesized that colon cancer with only retroperitoneal invasion is associated with a low risk of peritoneal dissemination. This study aimed to compare the risk of metachronous peritoneal metastases (mPM) between intraperitoneal and retroperitoneal invasion. METHODS In this international, multicenter cohort study, patients with pT4bN0-2M0 colon cancer who underwent curative surgery were categorized as having intraperitoneal invasion (e.g. bladder, small bowel, stomach, omentum, liver, abdominal wall) or retroperitoneal invasion only (e.g. ureter, pancreas, psoas muscle, Gerota's fascia). Primary outcome was 5-year mPM cumulative rate, assessed by Kaplan-Meier analysis. RESULTS Out of 907 patients with pT4N0-2M0 colon cancer, 198 had a documented pT4b category, comprising 170 patients with intraperitoneal invasion only, 12 with combined intra- and retroperitoneal invasion, and 16 patients with retroperitoneal invasion only. At baseline, only R1 resection rate significantly differed: 4/16 for retroperitoneal invasion only versus 8/172 for intra- +/- retroperitoneal invasion (p = 0.010). Overall, 22 patients developed mPM during a median follow-up of 45 months. Two patients with only retroperitoneal invasion developed mPM, both following R1 resection. The overall 5-year mPM cumulative rate was 13% for any intraperitoneal invasion and 14% for retroperitoneal invasion only (Log Rank, p = 0.878), which was 13% and 0%, respectively, in patients who had an R0 resection (Log Rank, p = 0.235). CONCLUSION This study suggests that pT4b colon cancer patients with only retroperitoneal invasion who undergo an R0 resection have a negligible risk of mPM, but this is difficult to prove because of its rarity. This observation might have implications regarding individualized follow-up.

Abstract
Objective This systematic review aims to assess the incidence of pouch failure and the correlation between ileal pouch-anal anastomosis (IPAA)-related complications and pouch failure. Background Previous studies demonstrated wide variation in postoperative complication rates following IPAA. Methods A systematic review was performed by searching the MEDLINE, EMBASE, and Cochrane Library databases for studies reporting on pouch failure published from January 1, 2010, to May 6, 2020. A meta-analysis was performed using a random-effects model, and the relationship between pouch-related complications and pouch failure was assessed using Spearman's correlations. Results Thirty studies comprising 22,978 patients were included. Included studies contained heterogenic patient populations, different procedural stages, varying definitions for IPAA-related complications, and different follow-up periods. The pooled pouch failure rate was 7.7% (95% confidence intervals: 5.56-10.59) and 10.3% (95% confidence intervals: 7.24-14.30) for studies with a median follow-up of ≥5 and ≥10 years, respectively. Observed IPAA-related complications were anastomotic leakage (1-17%), pelvic sepsis (2-18%), fistula (1-30%), stricture (1-34%), pouchitis (11-61%), and Crohn's disease of the pouch (0-18%). Pelvic sepsis (r = 0.51, P < 0.05) and fistula (r = 0.63, P < 0.01) were correlated with pouch failure. A sensitivity analysis including studies with a median follow-up of ≥5 years indicated that only fistula was significantly correlated with pouch failure (r = 0.77, P < 0.01). Conclusions The single long-term determinant of pouch failure was pouch fistula, which is a manifestation of a chronic leak. Therefore, all effort should be taken to prevent an acute leak from becoming a chronic leak by early diagnosis and proactive management of the leak. Mini abstract This systematic review aims to assess the incidence of pouch failure and the correlation between IPAA-related complications and pouch failure. Long-term pouch failure was correlated with fistula, suggesting that early septic complications may result in fistula formation during long-term follow-up, leading to an increased risk of pouch failure.

Abstract
BACKGROUND Resections for Crohn's disease should be limited and only resect macroscopically affected bowel. However, recent studies suggest microscopic inflammation at resection margins as a predictor for postoperative recurrence. The clinical impact remains unclear, as non-uniform pathological criteria have been used. The aim of this study was to assess the predictive value of pathological characteristics at ileocecal resection margins for recurrence. METHODS Both resection margins of 106 consecutive patients undergoing ileocecal resection for Crohn's disease between 2002 and 2009 were revised and scored for active inflammation, myenteric plexitis, and granulomas. Pathological findings were correlated to recurrence, defined as recurrent disease activity demonstrated by endoscopy (modified Rutgeerts score ≥i2) requiring upscaling medical treatment, using multivariate analysis. RESULTS Active inflammation was found at the proximal and distal resection margin in 27% and 15% of patients, respectively, myenteric plexitis in 37% and 32%, respectively, and granulomas in 4% and 6%, respectively. In total, 47 out of 106 patients developed recurrence. Only active inflammation at the distal colonic resection margin was an independent significant predictor for recurrence (88% vs 43% vs 51% for distal, proximal, and no involved margins, respectively; P < 0.01). CONCLUSION Active inflammation at the distal colonic resection margin after ileocecal resection identifies a patient group at high risk for postoperative recurrence both at the anastomotic site and the colon because it identifies undiagnosed L3 disease. These patients have a different and more aggressive natural history and require more intense medical treatment. Therefore, pathological evaluation of the distal resection margin should be implemented in daily practice.

Abstract
BACKGROUND Multivisceral resection for T4b colon cancer constitutes a heterogeneous group of surgical procedures. The purpose of this study was to explore clinically distinct categories of multivisceral resection, with subsequent correlation to postoperative complications and oncological outcomes. METHODS In this multicenter cohort study, all consecutive patients without metastases who underwent multivisceral resection for pT4bN0-2M0 colon cancer between 2000 and 2014 were included. Multivisceral resection was divided into four categories: (i) gastrointestinal (including the stomach), (ii) urologic ((partial) bladder and ureter), (iii) solid organ (spleen, kidney, liver, pancreas, and uterus), and (iv) abdominal wall/omentum/ovaries. The primary outcome was surgical complications and secondary outcomes were 5-year intra-abdominal recurrence, disease-free survival, and overall survival. RESULTS In total, 130 patients who underwent curative intent resection of pT4 colon cancer were included. Patients who underwent multivisceral resection within multiple categories were assigned to one of the categories based on hierarchy of clinical impact after exploratory analysis. For the primary endpoint, 55 patients were assigned to gastrointestinal, 14 to urologic, 14 to solid organ, and 47 to abdominal wall/omentum/ovaries multivisceral resection. Gastrointestinal multivisceral resection was independently associated with surgical complications (HR 3.9, 95% CI 1.4-10.6). Abdominal wall/omentum/ovaries multivisceral resection was significantly related with intra-abdominal recurrence (HR 7.8, 95% CI 1.0-57.8). The 5-year disease-free survival and overall survival showed no significant differences per multivisceral resection category. CONCLUSIONS Multivisceral resections for T4b colon cancer are heterogeneous procedures considering risk profiles. The proposed multivisceral resection subclassification needs validation, but might improve comparability between studies and hospitals (auditing).
