AbstractAimCrohn's disease (CD) is regarded as a wasting disease, yet there is a growing population of CD patients with a body mass index (BMI) of 35 and above. The rate of postoperative complications is relatively high in CD patients but might be even higher in CD with morbid obesity (MO).MethodsThis was a retrospective study using a prospectively maintained database of all patients undergoing Ileocolic resection for CD between 2014 and 2021 in two referral centres, comparing postoperative complication rates according to BMI.ResultsThree hundred and forty‐six patients were identified. Sixty patients (17%) had a BMI over 30 kg/m2, and 28 (8.1%) had a BMI of over 35 kg/m2 (>35 group). The BMI >35 group had more women (78.6% vs. 52%, P < 0.1), a higher rate of patients not receiving an anastomosis (7.1% vs. 2.5%, P = 0.02), a higher rate of any postoperative surgical complication (32.1% vs. 25.2%, P = 0.4), with a higher rate of Clavien–Dindo ≥3 (14.3% vs. 7.2%, P = 0.25), a higher rate of stoma creation on reoperation for complications (7.2% vs. 1.7%, P = 0.04), a higher rate of 30‐day readmission due to intra‐abdominal abscess (10.7% vs. 4.7%, P = 0.2), but a lower rate of postoperative medical complications (3.6% vs. 15.7%, P < 0.01).ConclusionsThe rate of MO among CD patients requiring ileocolonic resection is on the rise. MO in this setting is associated with statistically non‐significant increases in all surgical complications, severe complications, readmission, and a higher chance for a bailout stoma creation upon reoperation. However, MO seems to be a protective factor for medical postoperative complications, which might suggest better nutritional status.

AbstractAimLocally 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.MethodThis 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.ResultsAmong 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.ConclusionAbnormal 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.

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.

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.

RESECCIÓN ILEOCÓLICA ROBÓTICA REDO PARA LA ENFERMEDAD DE CROHN: INFORME PRELIMINAR DE UN CENTRO DE ATENCIÓN 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.

Abstract Background Proctectomy is often recommended when Crohn’s proctitis becomes refractory to medical therapy. However, some surgeons offer a temporary diverting stoma in an effort to avoid a permanent stoma. The long-term efficacy of this approach is not well-established. Our aim was to determine the long-term effectiveness of fecal diversion in patients with refractory Crohn’s proctitis. Methods This retrospective study included all patients with Crohn’s proctitis who underwent formation of a diverting ileostomy or colostomy for refractory disease from, 1998 to, 2019 in Mayo Clinic Rochester MN. Outcomes were disease recurrence, rate of stoma closure, and proctectomy. Univariate comparisons among categorical variables were performed with Pearson’s Chi-square and continuous variables using the student t-test. The cumulative probability of stoma closure was performed with a Kaplan Meier log-rank analysis. Multivariable analysis of risk factors for proctectomy and permanent stoma was achieved with logistic regression. Results Ninety-seven patients (55.7% female) were included. Ileostomy was the most common stoma type (88.7%, n=86), and colostomy was (11.3%, n=11) (Table.1). Median follow-up was, 4 years (range, 0–14). Active Crohn’s at follow-up was reported in, 68.1%. Only, 41.2% of patients underwent attempt at stoma reversal, and, 42.3% required a proctectomy (median, 19.5 months after diversion). At last follow-up, 29.9% were stoma-free, 42.3% had a new permanent stoma, and, 27.8% had the original diverting stoma (Fig.1). The multivariable predictors of proctectomy and permanent stoma were the recurrence of active CD after diversion and the need for other CD-related surgery following stoma creation (Table.2). The limitations of the study are its small sample size and its retrospective nature. The cumulative probability of stoma closure was performed with a Kaplan Meier log-rank analysis (Fig.2). Conclusion Diversion is effective at alleviating symptoms of Crohn’s proctitis in selected patients but does not significantly change disease outcome. Only a small number can avoid a long-term stoma.

Abstract Background Minimally invasive surgery (MIS) is the first-line approach for ileocolic resection in patients with Crohn’s disease (CD) and it is safe and feasible even in complex cases. However, an open approach is still required, but indications to open ileocolic resection for CD are not well described. Methods All consecutive adult patients with CD who underwent elective ileocolic resection in the Departments of Colon and Rectal Surgery at Mayo Clinic Rochester, Minnesota and Jacksonville, Florida between September 2014 and March 2021 were included and divided into “open” and “MIS” groups. Open approach was defined as upfront laparotomy, MIS included laparoscopic and robotic approaches, and conversion was defined as incision made earlier than planned. Indications to open approach were retrospectively reviewed by two authors, and any incongruity was resolved. Analogous indications were also assessed in the MIS group, as appropriate. Indications, baseline, perioperative characteristics, and short-term postoperative outcomes were compared between open and MIS. Results Among 319 ileocolic resections for CD, 45 (14.1%) were open and 274 (85.9%) MIS. Indications for open approach were severe disease, adhesions at previous surgery, history of abdominal sepsis, multifocal and extensive disease, abdominal wall involvement, concomitant open procedures, small bowel dilatation, and anaesthesiologic contraindications (Table 1). In addition, two or more of the above indications were present in 40 patients (89%) in the open group, while only in 6 patients (2%) in the MIS group (p&lt;0.001). Compared to MIS patients, patients undergoing open ileocolic resection were older, with longer CD duration, more previous surgery and preoperative intra-abdominal abscess drainage (Table 2). Nine patients were converted in the MIS group (3.3%). Intraoperatively, open group had more adhesiolysis ≥45 min, more intraoperative complications, more blood loss, more primary stoma, less anastomosis, and longer operative time (Table 3). Postoperatively, they had more overall postoperative complications, ileus, surgical site infections, dehydration, vascular thromboembolism, higher severity by Clavien-Dindo classification, and longer length of stay (Table 4). Conclusion Overall rate of open approach ileocolic resection for CD was 14 % during a 7-years period in a referral centre. Open approach was the only operation performed in cases of abdominal wall involvement, concomitant open procedures, and anaesthesiologic contraindication. In addition, the presence of at least two indications,predicting high technical complexity, may be considered as a no-go for the MIS approach in ileocolic resections for CD.

Abstract 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.
