Stapled End-To-Side Ileocolic Anastomosis in Crohn's Disease: Old Dog, Reliable Tricks? A Retrospective Two-Center Cohort Study.

Objective: Analyze our long-term experience with a less-popularized but stalwart approach, the stapled end-to-side ileocolic anastomosis. Background: The choice of technical approach to ileocolic anastomosis after ileocecal resection for Crohn's disease affects surgical outcomes and recurrence. Yet, despite heterogeneous data from different anastomotic configurations, there remains no clear guidance as to the optimal technique. Methods: In a retrospective cohort design, patients undergoing ileocolic anastomosis in the setting of Crohn's disease between 2016 and 2021 at two institutions were identified. Patient characteristics and surgical outcomes in terms of recurrence (surgical, clinical, and endoscopic) were studied. Results: In total, 211 patients were included. Before surgery, 80% were exposed to at least 1 cycle of systemic steroids and 71% had at least 1 biologic agent; 60% exhibited penetrating disease and 38% developed an intra-abdominal abscess. After surgery, one anastomosis leaked (0.5%). Over 2.4 years of follow-up (IQR = 1.3-3.9), surgical recurrence was 0.9%. Two-year overall recurrence-free and endoscopic recurrence-free survivals were 74% and 85% (95% CI = 68-81 and 80-91), respectively. The adjusted hazard ratio of endoscopic recurrence was 3.0 (95% CI = 1.4-6.2) for males and 5.2 (1.2-22) for patients who received systemic steroids before the surgery. Conclusion: The stapled end-to-side anastomosis is an efficient, reliable, and reproducible approach to maintain bowel continuity after ileocecal resection with durable outcomes. Our outcomes demonstrate low rates of disease recurrence and stand favorably in comparison to other more technically complex or protracted anastomotic approaches. This anastomosis is an ideal reconstructive approach after ileocecal resection for Crohn's disease.

Cancer in the Anal Transition Zone and Ileoanal Pouch following Surgery for Ulcerative Colitis.

Restorative proctocolectomy with ileal pouch-anal anastomosis remains the gold standard treatment for patients with ulcerative colitis who desire restoration of intestinal continuity. Despite a significant cancer risk reduction after surgical removal of the colon and rectum, dysplasia and cancers of the ileal pouch or anal transition zone still occur and are a risk even if an anal canal mucosectomy is performed. Surgical care and maintenance after ileoanal anastomosis must include consideration of malignant potential along with other commonly monitored variables such as bowel function and quality of life. Cancers and dysplasia of the ileal pouch are rare but sometimes difficult-to-manage sequelae of pouch surgery.

Simulation in Surgical Resident Education: A Porcine Hemostasis and Laparoscopic Model.

The steep learning curve associated with learning laparoscopic techniques and limited training opportunities represents a challenge to general surgery resident training. The objective of this study was to use a live porcine model to improve surgical training in laparoscopic technique and management of bleeding. Nineteen general surgery residents (ranging from PGY 3 to 5) completed the porcine simulation and completed pre-lab and post-lab questionnaires. The institution's industry partner served as sponsors and educators on hemostatic agents and energy devices. Residents had a significant increase in confidence with laparoscopic techniques and the management of hemostasis (P = .01 and P = .008, respectively). Residents agreed and then strongly agreed that a porcine model was suitable to simulate laparoscopic and hemostatic techniques, but there was no significant change between pre- and post-lab opinions. This study demonstrates that a porcine lab is an effective model for surgical resident education and increases resident confidence.

Management of the Hostile Abdomen.

Caring for a patient with a hostile abdomen is one of the most challenging clinical situations one can encounter. It requires specialized technical skill coupled with bold but thoughtful decision-making to achieve good outcomes. An approach to the patient with a complex, hostile abdomen must be individualized to account for the patient's personal details. However, implementing an experienced-based algorithm to help make the difficult decisions required in this setting can be helpful, as evidence-based studies are few. The purpose of this review is to provide a structured, evidence, and experienced-based approach to the challenges that the surgeon encounters when faced with a patient with a hostile abdomen, and to discuss perioperative and intraoperative surgical strategies that can lead to most successful outcomes.

Management of pouch neoplasia: consensus guidelines from the International Ileal Pouch Consortium.

Surveillance pouchoscopy is recommended for patients with restorative proctocolectomy with ileal pouch-anal anastomosis in ulcerative colitis or familial adenomatous polyposis, with the surveillance interval depending on the risk of neoplasia. Neoplasia in patients with ileal pouches mainly have a glandular source and less often are of squamous cell origin. Various grades of neoplasia can occur in the prepouch ileum, pouch body, rectal cuff, anal transition zone, anus, or perianal skin. The main treatment modalities are endoscopic polypectomy, endoscopic ablation, endoscopic mucosal resection, endoscopic submucosal dissection, surgical local excision, surgical circumferential resection and re-anastomosis, and pouch excision. The choice of the treatment modality is determined by the grade, location, size, and features of neoplastic lesions, along with patients' risk of neoplasia and comorbidities, and local endoscopic and surgical expertise.

Equivalent Operative Outcomes for Emergency Colon Cancer Resections Among Acute Care Surgeons and Specialists in Colorectal Surgery.

OBJECTIVES: Improved screening has decreased but not eliminated the need for emergent surgery for colon cancer (CC), many of which are performed by acute care surgery (ACS) surgeons. This retrospective review compares outcomes for CC resections on the ACS service to the surgical oncology and colorectal services (SO/CRS). METHODS: Retrospective review was performed for CC operations between 2014 and 2019. Data for margin status, cancer stage, number of lymph nodes dissected, time to medical oncology follow-up, and time to initiation of chemotherapy were collected. Patients with curative resection, who chose comfort care, presented on alternative services or with non-CC indications as well as those were lost to follow-up were excluded. RESULTS: 36 ACS patients and 269 SO/CRS patients underwent CC resections. Most ACS patients presented emergently compared to the SO/CC group (83.3% vs 1%, P < .05) as well as with more advanced tumor stage. There were no statistically significant differences for presence of metastatic disease, number of lymph nodes obtained, or time to post-surgical care (in days) and chemotherapy initiation (in days). 3 (8%) EGS patients had positive margins compared to 6 (2%) CRS/SO patients due to the presence of perforated tumors in the ACS group (p < .05). There were no statistically significant differences in 30- day or 1-year mortality despite the emergent presentation of the ACS patients. DISCUSSION: These findings suggest that despite emergent presentation and advanced disease burden, ACS surgeons provide quality care to CC patients, both in the operating room and in coordination of care.

Don't Forget about the K-Pouch!

The continent ileostomy (CI) was popularized by Nils Kock as a means to provide fecal continence to patients, most commonly in those with ulcerative colitis, after proctocolectomy. Although the ileal pouch-anal anastomosis (IPAA) now represents the most common method to restore continence after total proctocolectomy, CI remains a suitable option for highly selected patients who are not candidates for IPAA or have uncorrectable IPAA dysfunction but still desire fecal continence. The CI has exhibited a fascinating and marked evolution over the past several decades, from the advent of the nipple-valve to a distinct pouch design, giving the so-inclined and so-trained colorectal surgeon a technique that provides the unique patient with another option to restore continence. The CI continues to offer a means for appropriately selected patients to achieve the highest possible quality of life (QOL) and functional status after total proctocolectomy.

Postoperative Steroid Taper Is Associated With Pelvic Sepsis After Ileal Pouch-anal Anastomosis.

OBJECTIVE: We hypothesized that postoperative oral steroid taper after ileal pouch-anal anastomosis for inflammatory bowel disease would not be associated with pelvic septic complications. BACKGROUND: Recent data has emphasized the possible association between biologic medication use and pelvic sepsis following ileal pouch-anal anastomosis. Limited contemporary data exist examining the effects of steroid use on these complications. METHODS: Consecutive patients undergoing ileal pouch-anal anastomosis for inflammatory bowel disease at a single institution from January 2009 to December 2013 were included. Factors associated with anastomotic leak and pelvic sepsis were assessed using univariate and multivariate analysis. RESULTS: A total of 686 patients were included (mean age 39.5 years, 59% males). Postoperative oral steroid taper was associated with both anastomotic leak and pelvic sepsis on univariate analysis. Stress dose intravenous steroid use was not associated with complications. Multivariate analysis indicated total proctocolectomy (odds ratio [OR] 2.2; confidence interval [CI] 1.01-4.7, P = 0.047), and postoperative oral steroid taper (OR 2.3; CI 1.06-5.1; P = 0.035) as independent factors significantly associated with pelvic sepsis. CONCLUSIONS: Prolonged postoperative oral steroid taper after ileal pouch-anal anastomosis should be avoided. If preoperative steroid weaning is not possible before a planned total proctocolectomy and ileal pouch-anal anastomosis, patients should undergo an initial total abdominal colectomy.

Case-Matched Comparison of Long-Term Functional and Quality of Life Outcomes Following Laparoscopic Versus Open Ileal Pouch-Anal Anastomosis.

BACKGROUND: Laparoscopic ileal pouch-anal anastomosis (IPAA) is associated with recovery benefits when compared with open IPAA. There is limited data on long-term quality of life and functional outcomes, which this study aimed to assess. METHODS: An IRB-approved, prospectively maintained database was queried to identify patients undergoing laparoscopic IPAA (L), case-matched with open IPAA (O) based on age ± 5 years, gender, body mass index (BMI) ± 5 kg/m2, diagnosis, date of surgery ± 3 years, stapled/handsewn anastomosis, omission of diverting loop ileostomy and length of follow-up ± 3 years. We assessed functional results, dietary, social, work, sexual restrictions and the Cleveland Clinic global quality of life score (CGQoL) at 1, 2, 3, 4, 5 and 10 years postoperatively. Functional outcomes were assessed based on number of stools (day/night) and seepage protection use (day/night). Variables were evaluated with Kaplan-Meier survival curves, uni- and multivariable analyses. RESULTS: Out of 4595 IPAAs, 529 patients underwent L, of whom 404 patients were well matched 1:1 to an equivalent number of O based on all criteria. Median follow-ups were 2 (0.5-17.8) versus 2.4 (0.5-22.2) years in L versus O, respectively (p = 0.18). L was associated with significantly decreased number of stools at night and less frequent pad usage at 1 year, both during the day and at night. Functional outcomes became similar during further follow-up. L was also associated with improved overall CGQoL, and energy scores at 1 year postoperatively, and decreased social restrictions for 1-2 years. There were no significant differences in quality of health, dietary, work or sexual restrictions. Laparoscopy was not associated with increased risk of pouch failure (p = 0.07) or significantly different causes of pouch failure when compared to O. CONCLUSIONS: Laparoscopic and open IPAA are associated with equivalent long-term functional outcomes, quality of life and pouch survival rates. Laparoscopic technique is associated with temporary benefits lasting 1 or 2 years.

Outcomes of Endoscopic Balloon Dilation vs Surgical Resection for Primary Ileocolic Strictures in Patients With Crohn's Disease.

BACKGROUND & AIMS: Few studies have compared endoscopic balloon dilation (EBD) with ileocolic resection (ICR) in the treatment of primary ileocolic strictures in patients with Crohn's disease (CD). METHODS: We performed a retrospective study to compare postprocedure morbidity and surgery-free survival among 258 patients with primary stricturing ileo(colic) CD (B2, L1, or L3) initially treated with primary EBD (n = 117) or ICR (n = 258) from 2000 through 2016. Patients with penetrating disease were excluded from the study. We performed multivariate analyses to evaluate factors associated with surgery-free survival. RESULTS: Postprocedural complications occurred in 4.7% of patients treated with EBD and salvage surgery was required in 44.4% of patients. Factors associated with reduced surgery-free survival among patients who underwent EBD included increased stricture length (hazard ratio, 2.0; 95% CI, 1.3-3.3), ileocolonic vs ileal disease (hazard ratio, 10.9; 95% CI, 2.6-45.4), and decreased interval between EBD procedures (hazard ratio, 1.2; 95% CI, 1.1-1.4). There were no significant differences in sex, age, race, or CD duration between EBD and ICR groups. Patients treated with ICR were associated with more common postoperative adverse events (32.2%; P < .0001), but a reduced need for secondary surgery (21.7%; P < .0001) and significantly longer surgery-free survival (11.1 ± 0.6 vs 5.4 ± 0.6 y; P < .001). CONCLUSIONS: In this retrospective study, we found that although EBD is initially successful with minimal adverse events, there is a high frequency of salvage surgery. Initial ICR is associated with a higher morbidity but a longer surgery-free interval. The risks and benefits should be balanced in selecting treatments for individual patients.

Radiation-Induced Problems in Colorectal Surgery.

Radiotherapy not only plays a pivotal role in the cancer care pathways of many patients with pelvic malignancies, but can also lead to significant injury of normal tissue in the radiation field (pelvic radiation disease) that is sometimes as challenging to treat as the neoplasms themselves. Acute symptoms are usually self-limited and respond to medical therapy. Chronic symptoms often require operative intervention that is made hazardous by hostile surgical planes and unforgiving tissues. Management of these challenging patients is best guided by the utmost caution and humility.

Serrated Polyps and Serrated Polyposis Syndrome.

Colorectal serrated polyps are intermediate lesions in the serrated neoplastic pathway, which account for up to 30% of colorectal cancers. This pathway is biologically distinct from the adenoma-to-carcinoma sequence, with associated cancers exhibiting mutations in the BRAF oncogene, DNA promoter hypermethylation, and microsatellite instability. An evolving understanding of these unique lesions has led to the development of a more accurate classification, improved endoscopic identification, and tailored clinical management guidelines. This article reviews serrated polyps and serrated polyposis syndrome.

Risk factors and management of refractory or recurrent clostridium difficile infection in ileal pouch patients.

BACKGROUND: Clostridium difficile infection (CDI) is increasingly recognized in patients with ulcerative colitis with ileal pouch-anal anastomosis (IPAA). The aim of this study was to identify clinical risk factors for treatment-refractory or recurrent CDI in patients with IPAA. METHODS: We identified patients with IPAA for underlying ulcerative colitis and a positive polymerase chain reaction stool test for C. difficile at the Center for Ileal Pouch Disorders during the period from October 2010 to November 2013. Demographic clinical variables were compared between the refractory or recurrent CDI and nonrecurrent CDI groups. RESULTS: Patients with IPAA with refractory or recurrent symptoms (refractory/recurrent CDI, the study group, N = 19) were compared with patients with a single antibiotic-responsive episode of ileal pouch CDI (nonrecurrent CDI, the control group, N = 21). The frequency of pouchitis before the index CDI was similar in the study and control groups (63.2% versus 66.7%, P = 0.82). Postoperative mechanical abnormalities occurred in 16 patients (84.2%) in the study group versus 7 patients (33.3%) in the control group (P = 0.0008). There were no differences between the two groups regarding hospitalization, non-C. difficile antibiotic use, the use of gastric acid-reducing therapy, or immunosuppressives before or after the index CDI. Six of 15 patients (40.0%) in the study group versus 1 of 15 patients (7.1%) in the control group had a low serum level of IgG1 (P = 0.031). CONCLUSIONS: Refractory or recurrent disease is common in patients with ileal pouch with CDI. The presence of postsurgery mechanical intestinal complications or low serum immunoglobulin level may be risk factors for refractory or recurrent CDI in this patient population.

Consequences of anastomotic leak after restorative proctectomy for cancer: effect on long-term function and quality of life.

BACKGROUND: Long-term consequences of anastomotic leak after restorative proctectomy for rectal cancer, in terms of bowel function and quality of life, have been poorly delineated. OBJECTIVE: The purpose of this study is to evaluate the impact of anastomotic leak, when intestinal continuity can still be maintained, on bowel function and quality of life in patients undergoing rectal cancer resection with low colorectal or coloanal anastomoses. DESIGN: From 1980 to 2010, 864 patients undergoing restorative resection for rectal cancers were identified from a prospective cancer database. Anastomotic leak detected by a combination of clinical, radiographic, and operative means was diagnosed in 52 (6%) patients. MAIN OUTCOME MEASURES: Patients with anastomotic leak were compared with those without anastomotic leak for functional outcomes and quality of life at 1 year and most recent follow-up (mean 3.2 years) by using Short-Form 36 questionnaires (physical and mental component scales) and the Fecal Incontinence Severity Index. RESULTS: American Society of Anesthesiologists' class (p = 0.48), cancer stage (p = 0.39), and the use of neoadjuvant therapy (p = 0.4) were similar in the 2 groups. Patients with anastomotic leak were younger (56 years vs 61 years; p = 0.007), more likely to be male (82% vs 64%; p = 0.008), and more likely to have undergone proximal diversion at proctectomy (51.9% vs 26.6%; p = 0.001). One year after proctectomy, patients with anastomotic leak had worse physical and mental component scores (p = 0.01), more frequent daytime (p = 0.001) and nighttime bowel movements (p = 0.03), and worse control of solid stool (p = 0.01) in comparison with those without an anastomotic leak. At most recent follow-up (leak, 3.3 years vs no leak, 2.4 years), patients with an anastomotic leak reported worse mental component scores and increased use of perineal pads. CONCLUSION: Anastomotic leak after restorative resection for rectal cancer leads to early adverse consequences on bowel function and quality of life even when anastomotic continuity can be maintained. These findings may help counsel patients and clinicians regarding anticipated outcomes over the long term.

Surgical treatment of esophagogastric dysfunction forty years after reverse gastric tube esophagoplasty for congenital esophageal anomaly.

BACKGROUND: In 1968, Burrington first described use of the reverse gastric tube esophagoplasty for esophageal replacement in children with esophageal atresia or acquired stenosis. There are few documented cases of long-term follow-up of these patients. CASE REPORT: We describe a 41-year-old female who presented with progressive dysphagia 40 years after reverse gastric tube for a congenital esophageal stenosis as an infant. Repeated endoscopic dilations were unsuccessful in relieving her symptoms, and she subsequently underwent a modified Ivor-Lewis esophagogastrectomy with resection of the reverse gastric tube and reconstruction using her remaining gastric remnant. CONCLUSIONS: This report describes what we believe to be the longest recorded follow-up after reverse gastric tube esophagoplasty and highlights the potential for long-term complications after surgery for congenital anomalies.
