RESUMEN
PURPOSE: To evaluate the diagnostic performance of bowel wall enhancement for diagnosing concomitant bowel ischemia in patients with parietal pneumatosis (PI) diagnosed at abdominal CT. MATERIALS AND METHODS: From January 1, 2012 to December 31, 2021, 226 consecutive patients who presented with PI on abdominal CT from any bowel segment were included. Variables at the time of the CT were retrospectively extracted from medical charts. CT examinations were blindly analyzed by two independent radiologists. The third reader classified all disagreement of bowel enhancement in three categories: (1) normal bowel enhancement; (2) doubtful bowel wall enhancement; (3) absent bowel wall enhancement. Multivariable logistic regression analysis was performed. Concomitant bowel ischemia was defined as requirement of bowel resection specifically due to ischemic lesion in operated patients and death from bowel ischemia in non-operated patients. RESULTS: Overall, 78/226 (35%) patients had PI associated with concomitant bowel ischemia. At multivariate analysis, Only absence or doubtful bowel wall enhancement was associated with concomitant bowel ischemia (OR = 167.73 95%CI [23.39-4349.81], P < 0,001) and acute mesenteric ischemia associated with PP (OR = 67.94; 95%CI [5.18-3262.36], P < 0.009). Among the 82 patients who underwent a laparotomy for suspected bowel ischemia, rate of non-therapeutic laparotomy increased from 15/59 (25%), 2/6 (50%) and 16/17 (94%) when bowel wall enhancement was absent, doubtful and normal respectively. CONCLUSION: Absence of enhancement of the bowel wall is the primary feature associated with concomitant bowel ischemia. It should be carefully assessed when PI is detected to avoid non-therapeutic laparotomy.
RESUMEN
AIM: Minimally invasive surgery has been increasingly adopted for locally advanced colon cancer. However, evidence comparing robotic (RRC) versus laparoscopic right colectomy (LRC) for nonmetastatic pT4 cancers is lacking. METHODS: This was a multicentre propensity score-matched (PSM) study of a cohort of consecutive patients with pT4 right colon cancer treated with RRC or LRC. The two surgical approaches were compared in terms of R0, number of lymph nodes harvested, intra- and postoperative complication rates, overall (OS), and disease-free survival (DFS). RESULTS: Among a total of 200 patients, 39 RRC were compared with 78 PS-matched LRC patients. The R0 rate was similar between RRC and LRC (92.3% vs. 96.2%, respectively; p = 0.399), as was the odds of retrieving 12 or more lymph nodes (97.4% vs. 96.2%; p = 1). No significant difference was noted for the mean operating time (192.9 min vs. 198.3 min; p = 0.750). However, RRC was associated with fewer conversions to laparotomy (5.1% vs. 20.5%; p = 0.032), less blood loss (36.9 vs. 95.2 mL; p < 0.0001), fewer postoperative complications (17.9% vs. 41%; p = 0.013), a shorter time to flatus (2 vs. 2.8 days; p = 0.009), and a shorter hospital stay (6.4 vs. 9.5 days; p < 0.0001) compared with LRC. These results were confirmed even when converted procedures were excluded from the analysis. The 1-, 3- and 5-year OS (p = 0.757) and DFS (p = 0.321) did not significantly differ between RRC and LRC. CONCLUSION: Adequate oncological outcomes are observed for RRC and LRC performed for pT4 right colon cancer. However, RRC is associated with lower conversion rates and improved short-term postoperative outcomes.
RESUMEN
AIM: The aim of this work was to investigate the association between early postoperative anastomotic leakage or pelvic abscess (AL/PA) and symptomatic anastomotic stenosis (SAS) in patients after surgery for left colonic diverticulitis. METHOD: This is a retrospective study based on a national cohort of diverticulitis surgery patients carried out by the Association Française de Chirurgie. The assessment was performed using path analyses. The database included 7053 patients operated on for colonic diverticulitis, with surgery performed electively or in an emergency, by open access or laparoscopically. Patients were excluded from the study analysis where there was (i) right-sided diverticulitis (the initial database included all consecutive patients operated on for colonic diverticulitis), (ii) no anastomosis was performed during the first procedure or (iii) missing information about stenosis, postoperative abscess or anastomotic leakage. RESULTS: Of the 4441 patients who were included in the final analysis, AL/PA occurred in 327 (4.6%) and SAS occurred in 82 (1.8%). AL/PA was a significant independent factor associated with a risk for occurrence of SAS (OR = 3.41, 95% CI = 1.75-6.66), as was the case for diverting stoma for ≥100 days (OR = 2.77, 95% CI = 1.32-5.82), while central vessel ligation proximal to the inferior mesenteric artery was associated with a reduced risk (OR = 0.41; 95% CI = 0.19-0.88). Diverting stoma created for <100 days or ≥100 days was also a factor associated with a risk for AL/PA (OR = 3.08, 95% CI = 2-4.75 and OR = 12.95, 95% CI = 9.11-18.50). Interestingly, no significant association between radiological drainage or surgical management of AL/PA and SAS could be highlighted. CONCLUSION: AL/PA was an independent factor associated with the risk for SAS. The treatment of AL/PA was not associated with the occurrence of anastomotic stenosis. Diverting stoma was associated with an increased risk of both AL/PA and SAS, especially if it was left for ≥100 days. Physicians must be aware of this information in order to decide on the best course of action when creating a stoma during elective or emergency surgery.

BACKGROUND: HER2-targeted therapies have recently emerged as an option in the management of metastatic colorectal cancer (mCRC) overexpressing HER2. However, data regarding HER2 status in primary CRC and its corresponding liver metastases are limited, potentially influencing clinical decisions. Therefore, the aim of this study was to compare the HER2 status in primary CRC and paired liver metastases. METHODS: Patients with mCRC who were operated from their primary colorectal cancer and their corresponding synchronous or metachronous liver metastases, in the digestive surgery department of Besançon University Hospital, between April 1999 and October 2021, were included. Tissue microarrays were constructed from matched primary CRC and liver metastastic tissue samples. HER2 status was assessed by immunohistochemistry and in situ hybridization according to Valtorta's criteria. RESULTS: A series of 108 paired primary CRC and liver metastases, including a series of multiple liver metastases originating from the same patients (n = 24), were assessed. Among the primary CRC, 89 (82.4%), 17 (15.8%) and 2 (1.8%) cases were scored 0, 1 + and 2 + respectively. In liver metastases, 99 (91.7%), 7 (6.5%) and 2 (1.8%) were scored 0, 1 + and 2, respectively. Overall, there was a 19% discrepancy rate in HER2 status between primary CRC and metastases, which increased to 21% in cases with multiple synchronous or metachronous liver metastases in a given patient. No significant difference was found between metachronous and synchronous metastases regarding the HER2 status (p = 0.237). CONCLUSIONS: Our study highlights the temporal and spatial heterogeneity of HER2 status between primary CRC and corresponding liver metastases. These findings raise the question of a sequential evaluation of the HER2 status during disease progression, to provide the most suitable treatment strategy.

AIM: Although proximal faecal diversion is standard of care to protect patients with high-risk colorectal anastomoses against septic complications of anastomotic leakage, it is associated with significant morbidity. The Colovac device (CD) is an intraluminal bypass device intended to avoid stoma creation in patients undergoing low anterior resection. A preliminary study (SAFE-1) completed in three European centres demonstrated 100% protection of colorectal anastomoses in 15 patients, as evidenced by the absence of faeces below the CD. This phase III trial (SAFE-2) aims to evaluate the safety and effectiveness of the CD in a larger cohort of patients undergoing curative rectal cancer resection. METHODS: SAFE-2 is a pivotal, multicentre, prospective, open-label, randomized, controlled trial. Patients will be randomized in a 1:1 ratio to either the CD arm or the diverting loop ileostomy arm, with a recruitment target of 342 patients. The co-primary endpoints are the occurrence of major postoperative complications within 12 months of index surgery and the effectiveness of the CD in reducing stoma creation rates. Data regarding quality of life and patient's acceptance and tolerance of the device will be collected. DISCUSSION: SAFE-2 is a multicentre randomized, control trial assessing the efficacy and the safety of the CD in protecting low colorectal anastomoses created during oncological resection relative to standard diverting loop ileostomy. TRIAL REGISTRATION: NCT05010850.

BACKGROUND: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis. METHOD: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors. The urgent or elective nature of the surgical intervention was provided by the surgeon and in accordance with the indication for surgical treatment. A mixed logistic regression with a random intercept after multiple imputations by the chained equation was performed to consider the influence of missing data on the results. RESULTS: Between 2010 and 2021, 6,867 patients underwent surgery for sigmoid diverticulitis in the participating centers, of which one-third (n = 2317) were emergency cases. In multivariate regression analysis with multiple imputation by chained equation, increasing age, body mass index <18.5 kg/m2, neurologic and pulmonary comorbidities, use of anticoagulant drugs, immunocompromised status, and first attack of sigmoid diverticulitis were independent risk factors for emergency surgery. The likelihood of emergency surgery was significantly more frequent after national guidelines, which were implemented in 2017, only in patients with a history of sigmoid diverticulitis attacks. CONCLUSION: The present study highlights a high rate (33%) of emergency surgery for sigmoid diverticulitis in France, which was significantly associated with patient features and the first attack of diverticulitis.

INTRODUCTION: Nutritional intake and dysregulation of fatty acid metabolism play a role in the progression of various tumors, but the consumption of fatty acids is difficult to assess accurately with dietary questionnaires. Biomarkers can objectively assess intake, storage and bioavailability. OBJECTIVE: We studied the association between the polyunsaturated fatty acid (PUFA) composition of abdominal subcutaneous adipose tissue (good indicator of dietary intake over 2-3 years) and all-cause mortality. METHODS: In the multicenter AGARIC study, samples from 203 patients with colorectal cancer (CRC) undergoing curative surgery, were harvested from subcutaneous adipose tissue, which were then analyzed for PUFA composition. RESULTS: After a median follow-up of 45 months, 76 patients died. These patients were more often men (72.4% versus 57.5%, P = 0.04), diabetic (32.9% versus 13.4%, P = 0.001), old (median: 74.5 versus 66.6 years, P < 0.001) and with high alcohol consumption (47.4% versus 30.7%, P = 0.005). An increased risk of death was observed with higher levels of 20:2 ω-6 (hazard ratiotertile3 vstertile1 (HRT3vsT1) 2.12; 95% confidence interval (CI) 1.01-4.42; p-trend = 0.04), 22:4 ω-6 (HRT3vsT1 = 3.52; 95% CI = 1.51-8.17; p-trend = 0.005), and 22:5 ω-6 (HRT3vsT1 = 3.50; 95% CI = 1.56-7.87; p-trend = 0.002). Conversely, the risk of death seemed lower when higher concentrations of 18:3 ω-6 (HRT3vsT1 = 0.52; 95% CI = 0.27-0.99; p-trend = 0.04) and the essential fatty acid, α-linolenic acid 18:3 ω-3 (HRT3vsT1 = 0.47; 95% CI = 0.24-0.93; p-trend = 0.03) were observed. CONCLUSION: The risk of death was increased in CRC patients with higher concentrations of certain ω-6 PUFAs and lower concentrations of α-linolenic acid in their subcutaneous adipose tissue. These results reflect dietary habits and altered fatty acid metabolism. Our exploratory results warrant confirmation in larger studies with further exploration of the mechanisms involved.

OBJECTIVE: To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19. METHODS: From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21). RESULTS: A total of 1965 patients (A n = 1517, B n = 52, C n = 396) were included. The A group had significantly more previous SDD compared to the two other groups (p = 0.007), especially complicated (p = 0.0004). The rate of peritonitis was significantly higher in the B (46.1%) and C (38.4%) groups compared to the A group (31.7%) (p = 0.034 and p = 0.014). As regards surgical treatment, Hartmann's procedure was more often performed in the B group (44.2%, vs A 25.5% and C 26.8%, p = 0.01). Mortality at 90 days was significantly higher in the B group (9.6%, vs A 4% and C 6.3%, p = 0.034). This difference was also significant between the A and B groups (p = 0.048), as well as between the A and C groups (p = 0.05). There was no significant difference between the three groups in terms of postoperative morbidity. CONCLUSION: This study shows that the management of SDD was impacted by COVID-19 at CR, but also after and until September 2021, both on the initial clinical presentation and on postoperative mortality.

BACKGROUND AND AIMS: Postoperative recurrence is a major concern in Crohn's disease. The Kono-S anastomosis has been described to reduce the rate of recurrence. However, the level of evidence for its effectiveness remains low. The KoCoRICCO study aimed to compare outcomes between Kono-S anastomosis and conventional anastomosis in two nationwide prospective cohorts. METHODS: Adult patients with Crohn's disease who underwent ileocolonic resection with Kono-S anastomosis were prospectively included in seven referral centers between 2020 and 2022. Patients with conventional side-to-side anastomosis were enrolled from a previously published cohort. A propensity score analysis was performed to compare recurrence at first endoscopy in a matched 1:2 ratio population. RESULTS: A total of 433 patients with ileocolonic anastomosis were enrolled, of whom 155 had a Kono-S anastomosis. Before matching, both groups were unbalanced for preoperative, intraoperative, and postoperative characteristics. After matching patients with available endoscopic follow-up, endoscopic recurrence ≥i2 was found in 47.5% of the Kono-S group and 44.3% of the conventional side-to-side group (p=0.6745). CONCLUSIONS: The KoCoRICCO study suggests that Kono-S anastomosis does not reduce the risk of endoscopic recurrence in Crohn's disease compared to conventional side-to-side anastomosis. Further research with a longer follow-up is necessary to determine whether there is a potential benefit on surgical recurrence.
RESUMEN
BACKGROUND AND AIMS: In colorectal cancer (CRC), HER2 targeting is a promising treatment and immune infiltrate is an important area of research and strategy. Data regarding HER2 status and immune infiltrate are lacking. The aim of this study was to compare the immune infiltrate between HER2 amplified and non-amplified categories in proficient MisMatchRepair (pMMR)/microsatellite stable (MSS) CRC. METHODS: HER2 immunohistochemistry (IHC) and fluorescence in situ hybridization were performed in a retrospective series of 654 CRC. Lymphocyte infiltrate was analysed by anti-CD3, CD8 and CD4 IHC and evaluated digitally using QuPath software. RESULTS: Among the 654 CRC, we first observed a decreased CD3+ and CD8+ infiltrate between HER2 amplified (all IHC 3+ except one 2+) and non-amplified HER2 2+ IHC CRC (p = 0.059 and 0.072 respectively). A supplementary analysis of 258 pMMR/MSS CRC from the previous cohort, displaying all the IHC scores (0, 1+, 2+, 3+), showed a lower CD3+ infiltrate between HER2 amplified versus HER2 0 (p = 0.002), 1+ (p = 0.088) and non-amplified 2+ (p = 0.081) IHC cases. CONCLUSIONS: Our original findings suggest that in pMMR/MSS CRC, the immune infiltrate is reduced in HER2 amplified versus other HER2 categories. These data might be useful for future strategies combining anti-HER2 treatments and immune checkpoint inhibitors and need to be confirmed in larger CRC cohorts.
RESUMEN
PURPOSE: To assess the predictive value of combining CT and clinical findings for predicting 10-day mortality in critically ill patients in shock. MATERIALS AND METHODS: From January 1, 2018, to December 31, 2021, 289 consecutives critically ill patients in shock who underwent a contrast enhanced CT were included. Variables at the time of the CT were retrospectively extracted from medical charts. CT examinations were blindly analyzed by two independent radiologists. Multivariable analysis was performed, combining clinical and CT features. A simple survival score for 10-day mortality prediction was built and validated in a further independent external cohort of 70 patients. RESULTS: 10-day mortality rate was 135/289 (47%) in the study sample. At multivariate analysis, catecholamine infusion (OR = 2.11; 95%CI [1.21-4.18], P = 0.011), lactates level > 5 mmol/l (OR = 3.54; 95%CI [1.94-6.54], P < 0.001); total bilirubin > 50 mg/l (OR = 1.79 CI 95% [1.03-3.13], P = 0.039); small bowel dilation (OR = 1.82; 95%CI [1.01-3.32], P = 0.047); diffuse kidney infarction (OR = 2.76; 95%CI [1.26-6.37], P = 0.013) and superior mesentery artery < 5 mm (OR = 1.96; 95%CI [1.10-3.49], P = 0.021) were associated with 10-days mortality. The AUC of the combined model was 0.79; 95%CI [0.74-0.85] in the study sample and 0.87; 95%CI [0.71-0.91] in the validation cohort. CONCLUSION: The combination of CT imaging features and clinical data should emerge as a novel approach to predict short-term mortality in critically ill patients in shock.

Iatrogenic urinary tract injury (IUTI) is a severe complication of emergency digestive surgery. It can lead to increased postoperative morbidity and mortality and have a long-term impact on the quality of life. The reported incidence of IUTIs varies greatly among the studies, ranging from 0.3 to 1.5%. Given the high volume of emergency digestive surgery performed worldwide, there is a need for well-defined and effective strategies to prevent and manage IUTIs. Currently, there is a lack of consensus regarding the prevention, detection, and management of IUTIs in the emergency setting. The present guidelines, promoted by the World Society of Emergency Surgery (WSES), were developed following a systematic review of the literature and an international expert panel discussion. The primary aim of these WSES guidelines is to provide evidence-based recommendations to support clinicians and surgeons in the prevention, detection, and management of IUTIs during emergency digestive surgery. The following key aspects were considered: (1) effectiveness of preventive interventions for IUTIs during emergency digestive surgery; (2) intra-operative detection of IUTIs and appropriate management strategies; (3) postoperative detection of IUTIs and appropriate management strategies and timing; and (4) effectiveness of antibiotic therapy (including type and duration) in case of IUTIs.

BACKGROUND: Surgical resection rates remain high in Crohn's disease (CD). Reducing postoperative recurrence (POR) is challenging. Besides drug therapy, the surgical anastomosis technique may reduce POR. We aimed to compare the endoscopic POR rate after Kono-S vs standard ileocolic anastomosis. METHODS: The study included all consecutive CD patients operated on for ileocolic resection with a Kono-S anastomosis between February 2020 and March 2022. These patients were prospectively followed, and colonoscopy was performed 6 to 12 months after surgery. Patients were compared with a historical cohort of patients operated on with a conventional anastomosis in the same center. The primary end point was endoscopic POR (Rutgeerts score ≥i2). Factors associated with POR were assessed by univariate and multivariable analyses. RESULTS: A total of 85 patients were included, 30 in the Kono-S group and 55 in the control group. At baseline, there was no significant difference between the 2 groups regarding CD characteristics or known POR risk factors, including previous exposure to biologics. At 6 to 12 months, endoscopic POR rate did not differ significantly between groups (56.7% in the Kono-S group vs 49.1% in the control group; Pâ =â .50), nor did endoscopic POR according to the modified Rutgeerts score ≥i2b (46.7% in the Kono-S group vs 40% in the control group; Pâ =â .55). Severe endoscopic POR rates were 23.3% and 18.2% in each group, respectively. Clinical recurrence rate was similar in both groups, and no recurrent surgery occurred. By multivariable analysis, the type of anastomosis was not associated with endoscopic POR (OR, 1.229; 95% CI, 0.461-3.274, Pâ =â .68); however, postoperative treatment with anti-TNF was (OR, 0.337; 95% CI, 0.131-0.865 Pâ =â .02). CONCLUSIONS: Kono-S anastomosis was not associated with a reduced rate of endoscopic POR. These results warrant confirmation in prospective, randomized, multicenter studies.
This study aimed to evaluate the role of Kono-S anastomosis in postoperative recurrence (POR), in a prospective cohort of Crohn's disease patients undergoing ileocolic resection with this anastomosis. Results were compared with a historical cohort of patients who were operated on with conventional anastomosis. Endoscopic POR rate did not differ significantly between groups, and the type of anastomosis was not associated with endoscopic POR by multivariable analysis.
RESUMEN
OBJECTIVES: To assess the specific results of delayed coloanal anastomosis (DCAA) in light of its 2 main indications. BACKGROUND: DCAA can be proposed either immediately after a low anterior resection (primary DCAA) or after the failure of a primary pelvic surgery as a salvage procedure (salvage DCAA). METHODS: All patients who underwent DCAA intervention at 30 GRECCAR-affiliated hospitals between 2010 and 2021 were retrospectively included. RESULTS: Five hundred sixty-four patients (male: 63%; median age: 62 years; interquartile range: 53-69) underwent a DCAA: 66% for primary DCAA and 34% for salvage DCAA. Overall morbidity, major morbidity, and mortality were 57%, 30%, and 1.1%, respectively, without any significant differences between primary DCAA and salvage DCAA ( P = 0.933; P = 0.238, and P = 0.410, respectively). Anastomotic leakage was more frequent after salvage DCAA (23%) than after primary DCAA (15%), ( P = 0.016).Fifty-five patients (10%) developed necrosis of the intra-abdominal colon. In multivariate analysis, intra-abdominal colon necrosis was significantly associated with male sex [odds ratio (OR) = 2.67 95% CI: 1.22-6.49; P = 0.020], body mass index >25 (OR = 2.78 95% CI: 1.37-6.00; P = 0.006), and peripheral artery disease (OR = 4.68 95% CI: 1.12-19.1; P = 0.030). The occurrence of this complication was similar between primary DCAA (11%) and salvage DCAA (8%), ( P = 0.289).Preservation of bowel continuity was reached 3 years after DCAA in 74% of the cohort (primary DCAA: 77% vs salvage DCAA: 68%, P = 0.031). Among patients with a DCAA mannered without diverting stoma, 75% (301/403) have never required a stoma at the last follow-up. CONCLUSIONS: DCAA makes it possible to definitively avoid a stoma in 75% of patients when mannered initially without a stoma and to save bowel continuity in 68% of the patients in the setting of failure of primary pelvic surgery.
RESUMEN
BACKGROUND: Anastomotic leakage presentation after Ivor Lewis esophagectomy may vary on imaging. Such variations may influence anastomotic leakage management and outcomes. METHODS: All consecutive patients who underwent Ivor Lewis esophagectomy for cancer between 2012 and 2019 in 2 referral centers were included. Anatomical patterns of anastomotic leakage were defined on imaging as follows: eso-mediastinal anastomotic leakage was a leak contained in the posterior mediastinum, eso-pleural anastomotic leakage was a leak involving the pleural cavity, and eso-bronchial anastomotic leakage was a leak communicating with the tracheobronchial tract. According to the Esophageal Complications Consensus Group definition, management and 90-day mortality were evaluated according to these patterns. RESULTS: Among 731 patients, 111 (15%) developed anastomotic leakage consisting of eso-mediastinal anastomotic leakage (n = 87, 79%), eso-pleural anastomotic leakage (n = 16, 14%) and eso-bronchial anastomotic leakage (n = 8, 7%). There was no difference among these groups regarding preoperative characteristics or time to anastomotic leakage diagnosis. There was a significant difference in initial management according to anastomotic leakage anatomic patterns (P = .001). More than half of patients who experienced eso-mediastinal anastomotic leakage (n = 46, 53%) were initially treated conservatively without requiring intervention (Esophageal Complications Consensus Group type I), whereas most patients with eso-pleural anastomotic leakage (n = 14, 87.5%) and all with eso-bronchial anastomotic leakage (n = 8, 100%) initially required interventional or surgical treatment (Esophageal Complications Consensus Group type II-III). Anastomotic leakage anatomic patterns had a statistically significant impact on 90-day mortality, intensive care unit stay, and total hospital stay (P < .001). CONCLUSION: Anastomotic leakage anatomic patterns after Ivor Lewis esophagectomy influence outcomes. Further studies are warranted to validate it in a prospective setting. Anastomotic leakage anatomic patterns may help in guiding anastomotic leakage management.

AIM: The long-term urological sequelae after iatrogenic ureteral injury (IUI) during colorectal surgery are not clearly known. The aims of this work were to report the incidence of IUI and to analyse the long-term consequences of urological late complications and their impact on oncological results of IUI occurring during colorectal surgery through a French multicentric experience (GRECCAR group). METHOD: All the patients who presented with IUI during colorectal surgery between 2010 and 2019 were retrospectively included. Patients with ureteral involvement needing en bloc resection, delayed ureteral stricture or noncolorectal surgery were not considered. RESULTS: A total of 202 patients (93 men, mean age 63 ± 14 years) were identified in 29 centres, corresponding to 0.32% of colorectal surgeries (n = 63 562). Index colorectal surgery was mainly oncological (n = 130, 64%). IUI was diagnosed postoperatively in 112 patients (55%) after a mean delay of 11 ± 9 days. Intraoperative diagnosis of IUI was significantly associated with shorter length of stay (21 ± 22 days vs. 34 ± 22 days, p < 0.0001), lower rates of postoperative hydronephrosis (2% vs. 10%, p = 0.04), anastomotic complication (7% vs. 22.5%, p = 0.002) and thromboembolic event (0% vs. 6%, p = 0.02) than postoperative diagnosis of IUI. Delayed chemotherapy because of IUI was reported in 27% of patients. At the end of the follow-up [3 ± 2.6 years (1 month-13 years)], 72 patients presented with urological sequalae (36%). Six patients (3%) required a nephrectomy. CONCLUSION: IUI during colorectal surgery has few consequences for the patients if recognized early. Long-term urological sequelae can occur in a third of patients. IUI may affect oncological outcomes in colorectal surgery by delaying adjuvant chemotherapy, especially when the ureteral injury is not diagnosed peroperatively.

BACKGROUND: This study aimed to compare the short- and long-term outcomes of robotic (RRC-IA) versus laparoscopic (LRC-IA) right colectomy with intracorporeal anastomosis using a propensity score matching (PSM) analysis based on a large European multicentric cohort of patients with nonmetastatic right colon cancer. METHODS: Elective curative-intent RRC-IA and LRC-IA performed between 2014 and 2020 were selected from the MERCY Study Group database. The two PSM-groups were compared for operative and postoperative outcomes, and survival rates. RESULTS: Initially, 596 patients were selected, including 194 RRC-IA and 402 LRC-IA patients. After PSM, 298 patients (149 per group) were compared. There was no statistically significant difference between RRC-IA and LRC-IA in terms of operative time, intraoperative complication rate, conversion to open surgery, postoperative morbidity (19.5% in RRC-IA vs. 26.8% in LRC-IA; p = 0.17), or 5-yr survival (80.5% for RRC-IA and 74.7% for LRC-IA; p = 0.94). R0 resection was obtained in all patients, and > 12 lymph nodes were harvested in 92.3% of patients, without group-related differences. RRC-IA procedures were associated with a significantly higher use of indocyanine green fluorescence than LRC-IA (36.9% vs. 14.1%; OR: 3.56; 95%CI 2.02-6.29; p < 0.0001). CONCLUSION: Within the limitation of the present analyses, there is no statistically significant difference between RRC-IA and LRC-IA performed for right colon cancer in terms of short- and long-term outcomes.

BACKGROUND: Identifying the 30% of adhesive small bowel obstructions (aSBO) for which conservative management will require surgery is essential. The association between the previously described radiological score and failure of the conservative management of aSBO remains to be confirmed in a large prospective multicentric cohort. Our aim was to assess the risk factors of failure of the conservative management of aSBO considering the radiological score. MATERIAL AND METHODS: This prospective observational study took place in 15 French centers over 3 months. Consecutive patients experiencing aSBO with no early surgery were included. The six radiological features from the Angers radiological computed tomography (CT) score were noted (beak sign, closed loop, focal or diffuse intraperitoneal liquid, focal or diffuse mesenteric haziness, focal or diffuse mesenteric liquid, and diameter of the most dilated small bowel loop > 40 mm). RESULTS: Two hundred and seventy nine patients with aSBO were screened. Sixty patients (21.5%) underwent early surgery, and 219 (78.5%) had primary conservative management. In the end, 218 patients were included in the analysis of the risk factors for conservative treatment failure. Among them, 162 (74.3%) had had successful management while for 56 (25.7%) management had failed. In multivariate analysis, a history of surgery was not a significant risk factor for the failure of conservative treatment (OR = 0.11; 95%CI = 0-1.23). A previous episode of aSBO was protective against the failure of conservative treatment (OR = 0.36; 95%CI = 0.15-0.85) and an Angers CT score ≥ 5 as the only individual risk factor (OR = 2.39; 95%CI = 1.01-5.69). CONCLUSION: The radiological score of aSBO is a promising tool in improving the management of aSBO patients. A first episode of aSBO and/or a radiological score ≥5 should lead physicians to consider early surgical management.

Background: The risk of conversion to open surgery is inevitably present during any minimally invasive colorectal surgical procedure. Conversions have been associated with adverse postoperative and oncologic outcomes. No previous study has evaluated the specific causes and consequences of conversion during a minimally invasive right colectomy (MIS-RC). Materials and Methods: We analyzed the Minimally invasivE surgery for oncologic Right ColectomY (MERCY) study database including patients who underwent laparoscopic or robotic RC because of colon cancer between 2014 and 2020. Descriptive analyses were performed to determine the different reasons for conversion. Uni- and multivariate logistic regressions were run to identify potential variables associated with this outcome. Cox regression analyses were used to evaluate the impact of conversion on tumor recurrence. Results: Over a total of 1574 MIS-RC, 120 (7.6%) were converted to open surgery. The main reasons for conversion were procedural difficulties related to adherences from previous abdominal surgical procedures (39.2%), or owing to large tumor size or infiltration of adjacent structures (26.7%). Only 16.7% of the conversions were caused by intraoperative medical or surgical complications. Converted patients required longer operative times and developed more postoperative complications, both overall (39.2% versus 27.5%; P = .006) and severe ones (13.3% versus 8.3%; P = .061). Male gender (odds ratio [OR] = 1.89 [95% confidence interval: 1.31-2.71]), obesity (OR = 1.99 [1.4-2.83]), prior abdominal surgery (OR = 1.68 [1.19-2.37]), and pT4 cancers (OR = 4.04 [2.86-5.69]) were independently associated with conversion. Conversion to open surgery was not significantly associated with tumor recurrence (hazard ratios = 1.395 [0.724-2.687]). Conclusions: Although conversion to open surgery during MIS-RC for cancer is associated with worsened postoperative outcomes, it seems not to impact on the oncologic prognosis.
