ABSTRACT Background Minimal‐invasive surgery (MIS) was proven beneficial in Crohn's Disease (CD). Intracorporeal anastomosis (ICA) represents a further improvement as it is associated with decreased complications and shorter hospitalization. Extracorporeal anastomosis (ECA) is preferred to ICA as it allows haptic feedback of the bowel and mesentery, which is historically required for bowel resection in CD to minimize recurrences. We compared ICA and ECA in terms of recurrences and complications. Methods All patients between 2016 and 2022 with Crohn's disease who underwent a MIS ileocecectomy were identified and divided into ICA and ECA groups. Exclusion criteria were open surgery, end ileostomies, follow‐up < 1 month, and ileocecectomy not due to CD. Results 107 patients were included in the ICA group (44.9% male, mean age of 40.2 [±16.6] years), while 270 patients were in the ECA group (46.7% male, mean age of 41.9 [±17.3] years). The rate of endoscopic recurrences with a Rutgeerts score > 2, clinical recurrence, and surgical recurrence were not statistically different between the two cohorts. On the multivariable analysis for endoscopic and clinical recurrences, the ICA/ECA approach was not significant. The ECA group revealed a higher overall complication rate (30.4% versus 15.9%, p = 0.004). The median length of stay was significantly reduced in the ICA group ( p < 0.001). Conclusion ICA seems to be safe in ileocecectomies for CD. The complication rate and length of stay were reduced while not affecting the endoscopic, clinical, and surgical recurrence rates. MIS technology provides enhanced visualization and haptic feedback, which could be used as surrogates for the tactile evaluation intra‐operatively.

Abstract Aim Rectal prolapse is a full‐thickness intussusception of the rectum beyond the anal canal. It is often mistaken for other anorectal pathologies, leading to inaccurate referrals to colorectal surgeons and inappropriate management. However, the frequency of misdiagnosis is not well characterized. We aimed to assess the diagnostic accuracy of rectal prolapse referrals to three tertiary medical centres. Methods This is a retrospective study of patients referred for rectal prolapse to colorectal surgeons at the Mayo Clinic in Rochester, Jacksonville, and Phoenix from 2020 to 2024. The primary outcome is the accuracy of rectal prolapse diagnosis. The secondary outcomes are factors that correlate with diagnostic accuracy. Results Rectal prolapse was inaccurately diagnosed in 38.7% (186/480) of patients. Among misdiagnosed patients, the correct diagnosis was haemorrhoids (68.0%, n = 134), pelvic floor dysfunction (24.3%, n = 48) and rectocele (18.7%, n = 37). A diagnosis of rectal cancer was found in 3 patients (1.5%). The most common presenting symptoms were protrusion (66.3%, n = 345) and bleeding (33.6%, n = 175). Among the referring physicians, only 50.5% ( n = 227) performed an anorectal examination. Overall, there was significant variability in diagnostic accuracy across different specialties, with the highest accuracy from colorectal practices (84.0%) and the lowest from urologists (50.0%). Internal medicine physicians had a lower diagnostic accuracy with anorectal examination than without, though it did not reach statistical significance (44.0% vs. 59.5%, p = 0.2). Conclusion Over one‐third of rectal prolapse referrals were incorrectly diagnosed. This study highlights the opportunity for further training of referring providers on anorectal pathologies to improve diagnostic accuracy which could reduce treatment delays and optimize clinical outcomes.

Background: Transanal total mesorectal excision (taTME) facilitates sphincter preservation in low rectal cancer. Preliminary results and functional outcomes from the North American multicenter phase II taTME trial (NCT03144765) have been published. Three-year outcomes are reported. Methods: Patients with stage I to III rectal adenocarcinoma were enrolled across 11 centers (2017–2022). Endpoints included TME grade, 3-year overall survival, disease-free survival, cancer-specific survival, recurrence, late (beyond 90 d) complications, and stoma-free survival. Surveillance followed National Comprehensive Cancer Network guidelines, with pelvic magnetic resonance imaging (MRI) at 3 years to assess for pelvic sidewall recurrence when possible. Kaplan–Meier analysis assessed oncologic outcomes. Results: One hundred patients underwent taTME for tumors at a median of 5.8 cm from the anal verge, with intersphincteric resection in 36% and handsewn anastomosis in 54%. Median follow-up was 50.9 months. Late complications occurred in 32 patients, including 21 severe (Clavien-Dindo ≥3). Late anastomotic complications occurred in 5 patients; one required surgical revision. Estimated 3-year overall survival, cancer-specific survival, and disease-free survival were 93.7%, 96.6%, and 84.6%, respectively. Distant recurrence occurred in 15 patients (median: 17.6 months), most commonly in the lung and liver. Locoregional recurrence occurred in 2 patients. Preoperative N stage, lymph node yield, tumor deposits, and perineural invasion were associated with recurrence. Among 100 patients diverted at taTME, 97% were stoma-free at 3 years; 4 patients later underwent secondary diversion. Conclusions: Three-year outcomes of this multicenter trial support the safety and efficacy of taTME in resectable mid and low rectal tumors, with outcomes comparable to contemporary studies. Longer-term oncologic and functional outcomes are needed.

Abstract Background Patients with Crohn disease (CD) face an elevated risk of developing small bowel adenocarcinoma (SBA), a malignancy characterized by late-stage diagnosis and poor prognosis. In this study we aimed to characterize surgical management and oncologic outcomes for CD-associated SBA. Methods A retrospective review was conducted across 3 tertiary IBD centers, analyzing 99 patients with CD who underwent surgery for SBA between 1992 and 2025. Data included patient demographics, CD history, surgical details, and oncologic outcomes. Results The median time from CD diagnosis to SBA was 25 years. The SBA diagnosis was incidental in 74.8% of cases, discovered during surgery for other complications. Tumors were predominantly located in the ileum (80.8%) and showed aggressive features: 56.6% were poorly differentiated (grade 3), and 85.9% were pathologically advanced (T3/T4 on TNM staging). Nodal involvement was present in 45.5% of patients, and 18.2% had distant metastases at diagnosis. A complete (R0) resection was achieved in 90.9% of surgeries, with a 30-day morbidity rate of 26.3%. After a median follow-up of 36 months, the distant recurrence rate was 28.3%, and overall mortality was 27.3% (18.2% cancer related). Conclusion In patients with long-standing CD, SBA is typically an incidental diagnosis made at an advanced stage. While high rates of complete surgical resection are possible, the prognosis remains guarded due to aggressive tumor biology and high recurrence rates. These findings highlight a critical need for improved risk stratification to guide surveillance and for the development of evidence-based adjuvant treatment strategies.

Background: Total mesorectal excision (TME) remains the gold standard for the resection of rectal cancer regardless of the modality: open, laparoscopic, or robotic. The transanal TME (TaTME) approach has been utilized to overcome the difficulties encountered with the dissection of tumors in the distal pelvis. Recently, a single-port robotic approach (rSPa) was introduced, where three arms and a camera emanate from a 2.5 cm diameter port. This report presents the first experience in the United States combining those two approaches (rSPa TaTME) in rectal cancer, evaluating its safety and oncologic outcomes. Methods: This is a retrospective review of our prospectively maintained rectal cancer database. Patient demographics, tumor characteristics, neoadjuvant treatment, and oncologic and surgical outcomes were recorded. Results: Between May 2022 and August 2024, ten patients (six females, four males) with a median age at surgery of 53 years (range: 38–85) and a mean BMI of 26 (±5) kg/m2 were included for analysis. The median distance of tumors from the anorectal junction was 3.2 cm (range: 2–5.3 cm). All patients had negative margins, with eight complete TME specimens, one near complete, and one incomplete. The mean number of lymph nodes harvested was 24 (±11). The average operative time was 351 (243–411) min. The average length of stay was four days. The ileostomy was reversed in nine out of ten patients. Six patients experienced complications within 30 days of surgery. There were no local or distal recurrences, with a mean follow-up of 20 months (range: 4–30). Conclusions: rSPa TaTME is a unique and innovative method of combining two minimally advanced approaches for the resection of distal rectal cancers, with acceptable surgical and oncologic outcomes.

Abstract Aim Reversal of diverting loop ileostomy (DLI) traditionally occurs at ≥12 weeks after formation. Early closure has been performed in attempts to reduce DLI‐associated morbidity. Therefore, the aim of this study was to determine whether time to stoma reversal impacts postoperative morbidity. Method A retrospective review was conducted using institutional‐level American College of Surgeons National Surgical Quality Improvement Program data for adult patients who underwent DLI closure between January 2012 and December 2021 across a multistate health system. Time to DLI closure was stratified into three groups: ≤12, 12–24 or 24–36 weeks. Additional data were obtained from the electronic medical record. The primary outcome was major morbidity after DLI closure. Results A total of 482 patients underwent DLI closure. Eighty four patients underwent closure at ≤12 weeks (17.4%), 300 at 12–24 weeks (62.2%) and 98 at 24–36 weeks (20.3%). The most common diagnosis at DLI formation was cancer ( n = 211, 43.8%). Patients in the ≤12 weeks closure group more commonly had ulcerative colitis or diverticular disease and a lower American Society of Anesthesiologists class than patients with closure at 24–36 weeks ( p < 0.05). There were no significant differences in complication severity, overall major morbidity or its individual components amongst the time to DLI closure groups. There were no differences in anastomotic leaks or need for laparotomy. On multivariable analysis, immunosuppressive therapy and preoperative haematocrit <30% were significant risk factors for major morbidity after DLI closure. Conclusion Major morbidity did not differ by time to DLI closure group, indicating that closure at ≤12 weeks is safe in selected patients.

INTRODUCTION: Evidence-based recommendations for sexual practices regarding anoreceptive intercourse (ARI) do not exist in patients with inflammatory bowel diseases undergoing restorative proctocolectomy with ileal pouch anal anastomosis (IPAA). This study surveys providers on perspectives and attitudes related to sexual practices after IPAA. METHODS: We developed a 23-item survey and distributed it to providers caring for patients with inflammatory bowel diseases. RESULTS: 95% of providers believe that it is important to discuss sexual orientation or practices before IPAA, but only 27% routinely discuss this. 50% did not feel comfortable and 74% did not feel confident discussing ARI recommendations with patients who underwent or will undergo IPAA. DISCUSSION: Future interventions should aim to standardize recommendations regarding feasibility and time line to safe ARI after IPAA.

AbstractBackgroundInflammatory bowel disease (IBD) affects more than 10 million people worldwide. Men and women are equally affected by Crohn's disease (CD). It has been shown that patients with CD are at an increased risk of a colorectal cancer (CRC) diagnosis and CRC‐related mortality. During the last two decades, biological therapies have revolutionized the treatment of CD. There are no current studies investigating the prevalence of CRC in patients with CD in the era of biological therapy and the possible features of patients with CD who are at high risk of developing CRC.AimWe aim to assess the prevalence of CRC, risk factors and profile of CRC in patients with CD receiving biological treatment compared with those who are not under biological therapy and the impact of CD‐associated colorectal strictures on CRC development. The study hypothesis is that the use of biological therapy in the control of CD activity may decrease the risk of developing CRC.Study design and settingAn international, retrospective, snapshot of the prevalence of CRC in patients with CD, reported according to the SPIRIT guidelines. The study will involve centres that hold regular IBD multidisciplinary team meetings and have both IBD colorectal surgeons and gastroenterologists. Each participating centre will provide a local consultant lead and a local trainee lead. Data will be collected within a 2‐year recruitment period (January 2017–January 2019).Study populationAdult patients who presented with CD during the study period. Patients with an incidental diagnosis of CD during evaluation for CRC will be excluded.Statistical planBaseline patient characteristics will be summarized using the appropriate descriptive statistics. Univariable, multivariable and Cox regression models will be used to identify factors significantly associated with CRC. For noncontinuous variables a comparison between the subgroups will be carried out using the chi‐square test corrected by Fisher's exact test if appropriate. A p‐value of <0.05 will be considered statistically significant.Data storageData will be stored on a secured server, pin‐code protected according to the local data management agreement.

Objective: To compare robotic-assisted proctectomy with ileal pouch-anal anastomosis (R-IPAA) outcomes and laparoscopic proctectomy with IPAA within a specialized robotic surgery center, using matching techniques to minimize potential confounding factors. Background: Minimally invasive approaches, particularly laparoscopy, have improved outcomes for patients with inflammatory bowel disease and familial adenomatous polyposis undergoing IPAA. Robotic-assisted surgery offers potential technical advantages, but its definitive superiority over laparoscopy in this context remains under debate. Methods: This retrospective, “Strengthening the Reporting of Observational Studies in Epidemiology”–compliant study analyzed 234 consecutive patients undergoing IPAA (117 robotic and 117 laparoscopic). Data encompassed patient demographics, intraoperative details, and postoperative outcomes. We employed various matching techniques to address potential bias. Primary endpoints focused on 30-day complications, readmissions, and reoperations, with secondary endpoints including hospital stay, blood loss, and stoma closure rates. Results: R-IPAA demonstrated a lower conversion rate to open surgery ( P = 0.02), a shorter hospital stay ( P = 0.04), and reduced blood loss ( P = 0.0003) compared with laparoscopic proctectomy with IPAA. While overall 30-day morbidity rates were similar ( P = 0.4), matched analyses suggested a trend towards fewer reoperations and 3-month IPAA-associated complications after diverting loop ileostomy closure in the robotic group. However, these differences did not reach statistical significance. Conclusions: In a high-volume robotic surgery center, R-IPAA reduced the risk of conversion to open surgery while reducing intraoperative blood loss and providing shorter lengths of stay with equivalent perioperative outcomes. Promising trends to reduce 30-day reoperations and surgical complications after diverting loop ileostomy closure were observed after a matching analysis.
