ABSTRACT
BACKGROUND: In patients with multifocal intestinal Crohn disease requiring surgery for complication or uncontrolled disease, resection of all the lesions may lead to diarrhea and malnutrition. METHODS: This is a single-center retrospective review of all patients undergoing targeted surgery for multifocal Crohn disease with at least one residual Crohn disease location left behind. The primary endpoint was the rate of insufficient control of residual Crohn disease lesions requiring redo-surgery targeting these lesions. The rate of clinical remission defined by Harvey-Bradshaw index <4 was studied over time. RESULTS: From January 2012 to August 2022, among 320 patients undergoing surgery for intestinal Crohn disease, 30 met all criteria. Before surgery, patients had received a mean of 3 medical treatment lines; 83% (n = 25) had a clinically active Crohn disease (Harvey-Bradshaw index ≥4). Surgery consisted in ileocolonic (n = 14;47%), small bowel (n = 5;17%) or colonic resection (n = 12;40%) and strictureplasty (n = 4;13%). Operative mortality was nil. Overall postoperative and severe morbidity rates were 15 of 30 (50%) and 3 of 30. Residual lesions were in the small bowel (n = 15;50%), the colon (n = 16;53%), and/or the rectum (n = 16;53%). Twenty-five patients (83%) had postoperative medical therapy. Median follow-up was 65. Six patients (20%) required reoperation for insufficient control of residual lesions at index surgery after a mean of 98 ± 8 months. The clinical remission rate increased from 17% before surgery to 59% at 6-12 months and 71% at 24 months. CONCLUSION: In patients with multifocal Crohn disease, surgery targeted to severe and complicated lesions combined with postoperative medical treatment is a safe and effective strategy.
ABSTRACT
BACKGROUND: E-cadherin, a major actor of cell adhesion in the intestinal barrier, is encoded by the CDH1 gene associated with susceptibility to Crohn Disease (CD) and colorectal cancer. Since epigenetic mechanisms are suspected to contribute to the multifactorial pathogenesis of CD, we studied CpG methylation at the CDH1 locus. The methylation of the CpG island (CGI) and of the 1st enhancer, two critical regulatory positions, was quantified in surgical specimens of inflamed ileal mucosa and in peripheral blood mononuclear cells (PBMC) of 21 CD patients. Sixteen patients operated on for a non-inflammatory bowel disease, although not normal controls, provided a macroscopically normal ileal mucosa and PBMC for comparison. RESULTS: In ileal mucosa, 19/21 (90%) CD patients vs 8/16 control patients (50%) (p < 0.01) had a methylated CDH1 promoter CGI. In PBMC, CD patients with methylated CGI were 11/21 (52%) vs 7/16 controls (44%), respectively. Methylation in the 1st enhancer of CDH1 was also higher in the CD group for each of the studied CpGs and for their average value (45 ± 17% in CD patients vs 36 ± 17% in controls; p < 0.001). Again, methylation was comparable in PBMC. Methylation of CGI and 1st enhancer were not correlated in mucosa or PBMC. CONCLUSIONS: Methylation of several CpGs at the CDH1 locus was increased in the inflamed ileal mucosa, not in the PBMC, of CD patients, suggesting the association of CDH1 methylation with ileal inflammation. Longitudinal studies will explore if this increased methylation is a risk marker for colorectal cancer.

AIM: Locally advanced rectal cancer (LARC) is commonly treated with neoadjuvant chemoradiotherapy (nCRT) and total mesorectal excision (TME) to reduce local recurrence (LR) and improve survival. However, LR, particularly associated with lateral lymph node (LLN) involvement, remains a concern. The aim of this study was to investigate preoperative factors associated with LLN involvement and their impact on LR rates in LARC patients undergoing nCRT and curative surgery. METHOD: This multicentre retrospective study, including four academic high-volume institutions, involved 301 consecutive adult LARC patients treated with nCRT and curative surgery between January 2014 and December 2019 who did not undergo lateral lymph node dissection (LLND). Baseline and restaging pelvic MRIs were evaluated for suspicious LLNs based on institutional criteria. Patients were divided into two groups: cLLN+ (positive nodes) and cLLN- (no suspicious nodes). Primary outcome measures were LR and lateral local recurrence (LLR) rates at 3 years. RESULTS: Among the cohort, 15.9% had suspicious LLNs on baseline MRI, and 9.3% had abnormal LLNs on restaging MRI. At 3 years, LR and LLR rates were 4.0% and 1.0%, respectively. Ten out of 12 (83.3%) patients with LR showed no suspicious LLNs at the baseline MRI. Abnormal LLNs on MRI were not independent risk factors for LR, distant recurrence or disease-free survival. CONCLUSION: Abnormal LLNs on baseline and restaging MRI assessment did not impact LR and LLR rates in this cohort of patients with LARC submitted to nCRT and curative TME surgery.

BACKGROUND: Open combined resections of colorectal primary tumors and synchronous liver metastases have become common in selected cases. However, evidences favoring a minimally invasive (MIS) approach are still limited. The aim of this study is to evaluate the outcomes of MIS vs. open synchronous liver and colorectal resections. METHODS: 384 cases of synchronous colorectal and liver resections performed at one institution were identified during the study period. MIS vs open approach were compared after a propensity score matching; surgical outcomes were analyzed. RESULTS: MIS cases featured longer operative time (399 vs 300 min, p < 0.001), fewer blood loss (200 vs 500 ml, p = 0.003), and shorter hospitalization (median LOS 4 vs 6 days, p = 0.001). No difference was observed between the two groups for use of Pringle maneuver (p = 0.083), intraoperative blood transfusion (p = 0.061), achievement of negative colorectal (p = 0.176) and liver margins (p = 1.000), postoperative complications (p = 1.000) and significant (Clavien-Dindo ≥ 3a) complications (p = 0.817), delay of adjuvant therapy due to complications (p = 0.555), 30- and 90-day mortality. CONCLUSION: Synchronous colorectal and liver metastases resections via a minimally-invasive approach in high-volume centers with appropriate expertise result in significantly lower blood loss and length of stay despite longer operative time in comparison to open, with no oncological inferiority.
ABSTRACT
PURPOSE: One-third of patients with Crohn's disease (CD) require multiple surgeries during their lifetime. So, reducing the incisional hernia rate is crucial. We aimed to define incisional hernia rates after minimally invasive ileocolic resection for CD, comparing intracorporeal anastomosis with Pfannenstiel incision (ICA-P) versus extracorporeal anastomosis with midline vertical incision (ECA-M). METHODS: This retrospective cohort compares ICA-P versus ECA-M from a prospectively maintained database of consecutive minimally invasive ileocolic resections for CD performed between 2014 and 2021 in a referral center. RESULTS: Of the 249 patients included: 59 were in the ICA-P group, 190 in the ECA-M group. Both groups were similar according to baseline and preoperative characteristics. Overall, 22 (8.8%) patients developed an imaging-proven incisional hernia: seven at the port-site and 15 at the extraction-site. All 15 extraction-site incisional hernias were midline vertical incisions [7.9%; p = 0.025], and 8 patients (53%) required surgical repair. Time-to-event analysis showed a 20% rate of extraction-site incisional hernia in the ECA-M group after 48 months (p = 0.037). The length of stay was lower in the intracorporeal anastomosis with Pfannenstiel incision group [ICA-P: 3.3 ± 2.5 vs. ECA-M: 4.1 ± 2.4 days; p = 0.02] with similar 30-day postoperative complication [11(18.6) vs. 59(31.1); p = 0.064] and readmission rates [7(11.9) vs. 18(9.5); p = 0.59]. CONCLUSION: Patients in the ICA-P group did not encounter any incisional hernias while having shorter hospital length of stay and similar 30-day postoperative complications or readmission compared to ECA-M. Therefore, more consideration should be given to performing intracorporeal anastomosis with Pfannenstiel incision during Ileocolic resection in patients with CD to reduce hernia risk.

Laparoscopy is the first-line approach in ileocolic resection for Crohn's disease. Emerging data has shown better short-term outcomes with robotic right colectomy for cancer when compared to laparoscopic approach. However, robotic ileocolic resection for Crohn's disease has only shown faster return to bowel function. We aimed to evaluate short-term outcomes of ileocolic resection for Crohn's disease between robotic intracorporeal anastomosis (RICA) and laparoscopic extracorporeal anastomosis (LECA). Patients undergoing minimally invasive ileocolic resections for Crohn's disease were retrospectively identified using a prospectively maintained database between 2014 and 2021 in two referral centers. Among the 239 patients, 70 (29%) underwent RICA while 169 (71%) LECA. Both groups were similar according to baseline and preoperative characteristics. RICA was associated with more intraoperative adhesiolysis and longer operative time [RICA: 238 ± 79 min vs. LECA: 143 ± 52 min; p < 0.001]. 30-day postoperative complications were not different between the two groups [RICA: 17/70(24%) vs. LECA: 54/169(32%); p = 0.238]. Surgical site infections [RICA: 0/70 vs. LECA: 16/169(10%); p = 0.004], intra-abdominal septic complications [RICA: 0/70 vs. LECA: 14/169(8%); p = 0.012], and Clavien-Dindo ≥ III complications [RICA: 1/70(1%) vs. LECA: 15/169(9%); p = 0.044] were less frequent in RICA. Return to bowel function [RICA: 2.1 ± 1.1 vs. LECA: 2.6 ± 1.2 days; p = 0.002] and length of stay [RICA: 3.4 ± 2.2 vs. LECA: 4.2 ± 2.5 days; p = 0.015] were shorter after RICA, with similar readmission rates. RICA demonstrated better short-term postoperative outcomes than LECA, with reduced Clavien-Dindo ≥ III complications, surgical site infections, intra-abdominal septic complications, shorter length of stay, and faster return to bowel function, despite the longer operative time.

Minimally invasive surgery (MIS) is the first-line approach for ileocolic resection in Crohn's disease (CD), and it is safe and feasible, even with severe penetrating CD or redo surgery. While MIS indications are continually broadening, challenging CD cases might still require an open approach. This study aimed to report rate and indications for an upfront open approach in ileocolic resection for CD. Comprehensive perioperative data for all consecutive patients undergoing ileocolic resection for CD between 2014 and 2021 in a high-volume referral center for CD and MIS, were collected retrospectively. Indications for an upfront open approach were reviewed separately by two authors according to the preoperative visit. Among 319 ileocolic resections for CD, 45 (14%) were open and 274 (86%) MIS. Two or more of the below indications were present in 40 patients (89%) in the open group, while only in 6 patients (2%) in the MIS group (p < 0.0001). Indications for upfront open approach were severe penetrating disease (58%), adhesions at previous surgery (47%), history of abdominal sepsis (33%), multifocal and extensive disease (24%), abdominal wall involvement (22%), concomitant open procedures (9%), small bowel dilatation (9%), and anesthesiologic contraindications (4%). MIS was never performed in a patient with abdominal wall involvement, concomitant open procedure, and anesthesiologic contraindication to MIS. This study can help guide patients, physicians, and surgeons. An abdominal wall involvement or the presence of two of the above indications predicts a high surgical complexity and may be considered as a no-go for the MIS approach. These criteria should prompt surgeons to strongly consider an upfront open approach to optimize the perioperative planning and care of these complex patients.

Symptomatic Uncomplicated Diverticular Disease (SUDD) is a syndrome within the diverticular disease spectrum, characterized by local abdominal pain with bowel movement changes but without systemic inflammation. This narrative review reports current knowledge, delivers practical guidance, and reveals challenges for the clinical management of SUDD. A broad and common consensus on the definition of SUDD is still needed. However, it is mainly considered a chronic condition that impairs quality of life (QoL) and is characterized by persistent left lower quadrant abdominal pain with bowel movement changes (eg, diarrhea) and low-grade inflammation (eg, elevated calprotectin) but without systemic inflammation. Age, genetic predisposition, obesity, physical inactivity, low-fiber diet, and smoking are considered risk factors. The pathogenesis of SUDD is not entirely clarified. It seems to result from an interaction between fecal microbiota alterations, neuro-immune enteric interactions, and muscular system dysfunction associated with a low-grade and local inflammatory state. At diagnosis, it is essential to assess baseline clinical and Quality of Life (QoL) scores to evaluate treatment efficacy and, ideally, to enroll patients in cohort studies, clinical trials, or registries. SUDD treatments aim to improve symptoms and QoL, prevent recurrence, and avoid disease progression and complications. An overall healthy lifestyle - physical activity and a high-fiber diet, with a focus on whole grains, fruits, and vegetables - is encouraged. Probiotics could effectively reduce symptoms in patients with SUDD, but their utility is missing adequate evidence. Using Rifaximin plus fiber and Mesalazine offers potential in controlling symptoms in patients with SUDD and might prevent acute diverticulitis. Surgery could be considered in patients with medical treatment failure and persistently impaired QoL. Still, studies with well-defined diagnostic criteria for SUDD that evaluate the safety, QoL, effectiveness, and cost-effectiveness of these interventions using standard scores and comparable outcomes are needed.
ABSTRACT
BACKGROUND: Although the safety of laparoscopic redo ileocolonic resection for Crohn's disease has been described before, the safety of robotic redo ileocolonic resection is still unelucidated. OBJECTIVE: This study aimed to share our preliminary experience regarding the safety of robotic redo ileocolonic resection for Crohn's disease. DESIGN: Retrospective analysis. SETTING: Tertiary care center. PATIENTS: All consecutive adult patients who underwent robotic ileocolonic resection for Crohn's disease at our institution between 2014 and 2021 were included. Patients were divided into redo ileocolonic resection and primary ileocolonic resection groups. PRIMARY OUTCOME MEASURES: Baseline demographics, preoperative risk factors, and intraoperative details were compared between both groups. The primary outcome was conversion to an open approach, and secondary outcomes were 30-day postoperative complications. RESULTS: A total of 98 patients were included. Of them, 18 (18.4%) had a redo ileocolonic resection. Patients who had a redo ileocolonic resection were more likely to have a longer duration of disease, associated anoperineal disease, a higher number of previous lines of medical treatments, received total parental nutrition before the operation for correction of malnutrition, and longer time for adhesiolysis. Patients who had redo ileocolonic resection had a higher risk for conversion to open ileocolonic resection [3 (16.7%) versus 2 (2.5%); p value = 0.04]. There was no statistically significant difference regarding the overall length of stay and the 30-day morbidity between both groups. No 30-day mortality or anastomotic leaks occurred in either group. LIMITATIONS: Retrospective nature of the analysis. CONCLUSIONS: Robotic redo ileocolonic resection showed similar short-term postoperative outcomes to robotic primary ileocolonic resection for Crohn's disease. However, conversion rates are higher in robotic redo ileocolonic resection yet seem lower than previously published results in laparoscopic surgery.

RESECCIN ILEOCLICA ROBTICA REDO PARA LA ENFERMEDAD DE CROHN INFORME PRELIMINAR DE UN CENTRO DE ATENCIN TERCIARIA: ANTECEDENTES:Si bien la seguridad de la resección ileocolónica laparoscópica para la enfermedad de Crohn se ha descrito antes, la seguridad de la resección ileocolónica robótica aún no se ha dilucidado.OBJETIVO:Este estudio tuvo como objetivo compartir nuestra experiencia preliminar con respecto a la seguridad de la resección ileocolónica robótica para la enfermedad de Crohn.DISEÑO:Análisis retrospectivo.AJUSTE:Centro de atención terciaria.PACIENTES:Se incluyeron todos los pacientes adultos consecutivos que se sometieron a resección ileocolónica robótica por enfermedad de Crohn en nuestra institución entre 2014 y 2021. Los pacientes se dividieron en grupos de resección ileocolónica reconfeccionada y resección ileocolónica primaria.MEDIDAS DE RESULTADO:Se compararon los datos demográficos iniciales, los factores de riesgo preoperatorios y los detalles intraoperatorios entre ambos grupos. El resultado primario fue la conversión a abierto y los resultados secundarios fueron las complicaciones posoperatorias a los treinta días.RESULTADOS:Se incluyeron un total de 98 pacientes. De ellos, 18 (18,4%) tuvieron resección ileocolónica. Los pacientes que se sometieron a una nueva resección ileocolónica tenían más probabilidades de tener una mayor duración de la enfermedad, enfermedad anoperineal asociada, un mayor número de líneas previas de tratamientos médicos, más probabilidades de haber recibido nutrición parental total antes de la operación para la corrección de la desnutrición y más tiempo tiempo de adhesiolisis. Los pacientes que se sometieron a una nueva resección ileocolónica tuvieron un mayor riesgo de conversión a cirugía abierta [3 (16,7 %) frente a 2 (2,5 %); valor p 0,04]. No hubo diferencia estadísticamente significativa con respecto a la duración total de la estancia y la morbilidad a los treinta días entre ambos grupos. No hubo mortalidad a los treinta días ni fugas anastomóticas en ninguno de los grupos.LIMITACIONES:Naturaleza retrospectiva del análisis.CONCLUSIÓN:La resección ileocolónica robótica mostró resultados postoperatorios a corto plazo similares a la resección ileocolónica primaria robótica para la enfermedad de Crohn. Sin embargo, las tasas de conversión son más altas en la resección ileocolónica robótica, pero parecen más bajas que los resultados publicados previamente en la cirugía laparoscópica.

BACKGROUND: During COVID-19 pandemic, hospitals changed visitation policy to limit the infection spread. We aimed to evaluate the impact of evolving visitation policy on short-term surgical outcomes. METHODS: All adult patients who underwent colorectal surgery between January 1st, 2020, and May 12th, 2020, at our institution were included. Patients were divided into: before implementing the no visitor allowed policy (VA) or no visitor allowed policy (NVA) groups, based on the hospital admission date.. The primary outcomes were 30-day readmission rate and length of stay (LOS). RESULTS: A total of 439 patients were included. Of them, 128 (29.2%) patients had surgery during the NVA policy, and 311 (70.8%) patients underwent surgery during VA policy. Patients who had surgery during the NVA policy were more likely to have emergency surgery and a longer operation time. However, the other baseline characteristics, surgical approach, underlying disease, extent of resection, and the need for intraoperative blood transfusion were comparable between the two groups. There was no difference between both groups regarding the 30-day readmission rate (10.3% vs. 7.8% in the NVA group; P>0.05) and median LOS (4 days vs. 3 days in the NVA group; P>0.05). CONCLUSIONS: Restricting inpatient visitors for patients undergoing colorectal surgery was not associated with increased postoperative complications and readmission rates. LOS was similar between the two groups. This strategy can be safely implemented in cases of crisis. Further studies are needed to confirm these findings.

BACKGROUND: Minimally invasive ileocolic resection for complicated Crohn disease, defined as penetrating Crohn disease associated with intra-abdominal fistula, abscess, or phlegmon, is challenging. In addition, the impact of the minimally invasive approach on postoperative outcomes is still debated. This study aimed to compare the intraoperative and postoperative outcomes of minimally invasive ileocolic resection for complicated versus uncomplicated Crohn disease. METHODS: A retrospective analysis of all consecutive adult patients with Crohn disease undergoing minimally invasive ileocolic resection from 2014 to 2021 was performed. Perioperative outcomes were compared between patients with complicated Crohn disease (complicated group) and patients without these lesions (uncomplicated group). RESULTS: Among the 274 patients undergoing minimally invasive ileocolic resection for Crohn disease, 101 (36.9%) had a robotic approach, and 84 (30.7%) had complicated Crohn disease. Complicated patients were more frequently malnourished (32.1% vs 16.1%, P = .004) and had more frequent previous bowel resections for Crohn disease (22.1% vs 9.5%, P = .002). There were no differences between both groups regarding intraoperative complications (1.1% uncomplicated group vs 2.4% complicated group, P = .463), conversion rate (2.6% uncomplicated group vs 4.8% complicated group, P = .463), postoperative morbidity (27.4% uncomplicated group vs 34.5% complicated group, P = .231), intra-abdominal septic complications (4.2% uncomplicated group vs 7.1% complicated group, P = .309), and length of stay (3.8 ± 2.0 days uncomplicated group vs 4.2 ± 3.0 complicated group, P = .188). CONCLUSION: Minimally invasive ileocolic resection for complicated Crohn disease is safe and feasible. Future prospective studies are needed to confirm these results.

BACKGROUND: There is controversy regarding the postoperative outcomes in Crohn's disease [CD] patients exposed to vedolizumab [VDZ] or ustekinumab [UST]. We aimed to describe our surgical outcomes in patients who underwent minimally invasive ileocolonic resection [MIS-ICR] for CD who had preoperative biologic therapy. METHODS: All consecutive adult patients who had MIS-ICR for CD between 2014 and 2021 at our institution were included. Patients were divided into four groups: VDZ, UST, anti-tumour necrosis factor [anti-TNF], and no biologic group. Timing between the last dose of biologics and surgery was per surgeon's discretion. The primary outcome was intra-abdominal septic complications. Secondary outcomes included all 30-day complications. RESULTS: A total of 274 patients were identified. Of these, 113 [41.2%] patients had received anti-TNF, 52 [19%] had received UST, and 19 [7%] had received VDZ. There was no difference between the four groups regarding baseline risk factors. There was no difference between the four groups regarding intra-abdominal septic complications [4.4% for no biologic, 5.3% for anti-TNF, 5.8% for UST, and 5.3% for VDZ; p = 0.987], surgical site infection rate, overall 30-day morbidity, overall 30-day readmission, overall surgical and medical complications, urinary tract infection, pulmonary infections, or length of stay. Those results were consistent after a subgroup analysis based on complexity of the disease. CONCLUSIONS: This retrospective analysis demonstrates an equivalent postoperative safety profile for patients treated with preoperative anti-TNF, VDZ, or UST versus no biologic therapy within 3 months of MIS-ICR for Crohn's disease. Preoperative biologic therapy may not increase complications after minimally invasive ileocolonic resection in Crohn's disease. Further studies with larger sample sizes are needed to confirm results.

Management of malignant left-sided colonic obstruction remains challenging and requires a stoma in 40-65% of patients. In those with obstructive splenic flexure colon cancer (OSFCC), a debate still exists regarding the most appropriate surgery. The aim of this muticenter study was to report and compare the different surgical procedures in OSFCC patients with a special focus on operative and histological characteristics and survival outcomes including 12-month stoma-free survival. Between 2000 and 2015, 2325 patients were treated for obstructive colon cancer in centers members of the French National Surgical Association (AFC). Among them, 198 underwent surgery for OSFCC and were retrospectively analyzed. Patients with OSFCC and proximal colonic ischemia or perforation were excluded. Four procedures were performed: decompressing stoma (DS, 39%), splenic flexure colectomy (SFC, 39%), subtotal colectomy (STC, 17%,) and left hemicolectomy (LHC, 5%). All patients treated with LHC underwent a Hartmann's procedure. There was no significant difference between groups for postoperative mortality and morbidity. Hospital stay was significantly longer after DS. The length of the specimen, longitudinal resection margins and number of harvested lymph nodes were significantly higher in the STC group. There was no difference for overall and disease-free survival. Stoma-free survival was significantly lower after LHC (62%) in comparison with the other groups (p < 0.0001). At the end of follow-up, 50% of patients who underwent LHC had a permanent stoma. In OSFCC patients without proximal colonic ischemia or peritonitis, LHC should no longer be recommended due to a high risk of permanent stoma.

OBJECTIVE: The aim of this study was to compare the survival of patients with stage II obstructing colon cancer (OCC) who had adjuvant chemotherapy with those who did not. SUMMARY BACKGROUND DATA: The need for adjuvant chemotherapy in stage II colon cancer is still debated. METHODS: All consecutive patients treated for a stage II OCC in a curative intent (with primary tumor resection) between January 2000 and December 2015 were included in this retrospective, multicenter cohort study which included a propensity score analysis using an odds of treatment weighting (Average Treatment effect on the Treated, ATT). The endpoint was the comparison between the 2 groups for overall survival (OS) and disease-free survival (DFS) according to whether or not patients received adjuvant chemotherapy. RESULTS: During the study period, 504 patients underwent a curative colectomy for a stage II OCC. Among these patients, 179 (35.5%) had adjuvant chemotherapy and 325 (64.5%) had no adjuvant treatment. Among the 179 patients who received adjuvant chemotherapy, 108 patients (60%) received oxaliplatin based regimen and 99 patients (55%) completed all scheduled cycles. At multivariate analysis, after weighting by the odds (ATT analysis) and adjustment, adjuvant chemotherapy after resection of a stage II OCC was associated with improvements in OS [hazard ratio (HR) = 0.42 (0.17-0.99), P = 0.0498] and DFS [HR = 0.57 (0.37-0.88), P = 0.0116]. CONCLUSION: This study suggests that adjuvant chemotherapy after curative resection of stage II OCC may improve oncological outcomes.

BACKGROUND: Although minimally invasive rectal surgery (MIRS) for cancer provides better recovery for similar oncologic outcomes over open approach, conversion is still required in 10% and its impact on short-term and long-term outcomes remains unclear. The aim of our study was to evaluate the impact of conversion on postoperative and oncologic outcomes in patients undergoing MIRS for cancer. METHODS: From June 2011 to March 2020, we reviewed 257 minimally invasive rectal resections for cancer recorded in a prospectively maintained database, with 192 robotic and 65 laparoscopic approaches. Patients who required conversion to open (Conversion group) were compared to those who did not have conversion (No conversion group) in terms of short-term, histologic, and oncologic outcomes. Univariate and multivariate analyses of the risk factors for postoperative morbidity were performed. RESULTS: Eighteen patients (7%) required conversion. The conversion rate was significantly higher in the laparoscopic approach than in the robotic approach (16.9% vs 3.6%, p < 0.01). Among the 4 reactive conversions, 3 (75%) were required during robotic resections. Patients in the Conversion group had a higher morbidity rate (83.3% vs 43.1%, p = 0.01) and more severe complications (38.9%, vs 18.8%, p = 0.041). Male sex [HR = 2.46, 95%CI (1.41-4.26)], total mesorectal excision [HR = 2.89, 95%CI (1.57-5.320)], and conversion (HR = 4.87, 95%CI [1.34-17.73]) were independently associated with a higher risk of overall 30-day morbidity. R1 resections were more frequent in the Conversion group (22.2% vs 5.4%, p = 0.023) without differences in the overall (82.7 ± 7.0 months vs 79.4 ± 3.3 months, p = 0.448) and disease-free survivals (49.0 ± 8.6 months vs 70.2 ± 4.1 months, p = 0.362). CONCLUSION: Conversion to laparotomy during MIRS for cancer was associated with poorer postoperative results without impairing oncologic outcomes. The high frequency of reactive conversion due to intraoperative complications in robotic resections confirmed that MIRS for cancer is a technically challenging procedure.

To date, there is no cohort in the literature focusing on the impact of the type of anastomosis in robotic ileocolonic resections for Crohn's Disease (CD). We aimed to compare short-term postoperative outcomes of robotic ileocolic resection for CD between patients who had intracorporeal (ICA) or extracorporeal anastomosis (ECA). We retrospectively included all consecutive robotic ileocolonic resections for CD at our institution between 2014 and 2020. We compared baseline, perioperative characteristics, and postoperative outcomes between ICA and ECA. The analysis included 89 patients: 71% underwent ICA and 29% ECA. Groups were similar in age, sex, body mass index, smoking, CD duration, Montreal classification, surgical history, and previous CD medical treatments. Return to bowel function was achieved sooner in the ICA group (ICA 1.6 ± 0.7 day, ECA 2.1 ± 0.8 days; p = 0.026) despite longer operative time (ICA 235 ± 79 min, ECA 172 ± 51 min; p < 0.001), but no statistical difference was found regarding ileus rate and length of stay. Overall, 30-day postoperative complication rate was 23.6% (ICA 22.2%, ECA 26.9%; p = 0.635). There were no abdominal septic complications, anastomotic leaks, or severe postoperative complications. In conclusion, robotic ileocolic resection for CD shows acceptable 30 days outcomes for both ICA and ECA. ICA was associated with a faster return to bowel function without impact on the length of stay or 30-day complications. Further studies are needed to confirm the benefits of ICA in the setting of ileocolic resections for CD.

There is limited data about the safety of colorectal surgery after immune checkpoint inhibitors (ICI). We aimed to share our experience about postoperative outcomes of colorectal surgery for patients treated with ICI. Overall, 31 patients were identified, 22 (71%) underwent elective and nine (29%) underwent emergent/urgent surgery. The 30-day Clavien Dindo class ≥ III complication rates were 27.3% (n = 6) for elective and 55.5% (n = 5) for emergent/urgent cases. Four patients underwent emergency surgery for immune-related colonic perforation and developed postoperative septic shock; two died. Considering patients' comorbidities, cancer stage, and surgical complexity, elective colorectal surgery after ICI seems relatively safe. However, emergent/urgent colorectal surgery was associated with high postoperative morbidity. Indeed, colonic perforation in the setting of ICI treatment has a significant risk of postoperative mortality. Therefore, for patients on ICI with any acute abdominal symptoms, surgical consult should be involved, and colon perforation should be ruled out.

AIM: Postoperative morbidity is high in patients operated on for Crohn's disease (CD) complicated by malnutrition. This study aimed to evaluate the impact of preoperative enteral nutritional support (PENS) on postoperative outcome in patients with CD complicated by malnutrition included in a prospective nationwide cohort. METHOD: Malnutrition was defined as body mass index <18 kg/m2 and/or albuminaemia <30 g/L and/or weight loss >10%. Failure of PENS was defined as the requirement for additional preoperative parenteral nutrition to PENS. Univariate analysis of the risk factors for PENS failure was performed. Propensity score matching (PSM) was used to compare the outcomes between 'upfront surgery' and 'PENS' groups. The primary endpoint was the rate of intra-abdominal septic morbidity and/or temporary defunctioning stoma. RESULTS: Among 592 patients included, 149 were selected. In the intention-to-treat population including 20 (13.4%) patients with PENS failure after PSM, 78 'upfront surgery' and 71 'PENS'-matched patients were compared, with no significant difference in the primary endpoint. Perforating CD and preoperative intra-abdominal fistula were associated with PENS failure [37.5 vs 16.1% (P = 0.047) and 41.2% vs 16.2% (P = 0.020), respectively]. After exclusion of these 20 patients, PSM was used to compare 45 'upfront surgery' and 51 'PENS'-matched patients, with a significantly decreased rate of intra-abdominal septic complications and/or temporary defunctioning stoma in the PENS group (19.6 vs 42.2%, P = 0.016). CONCLUSION: Preoperative enteral nutritional support is associated with a trend but no conclusive evidence of a reduction in intra-abdominal septic complications and/or requirement for defunctioning stoma. Patients with perforating CD complicated with malnutrition are at risk of PENS failure.
