Role of Age as a Predictor of Major Complications After Elective Surgery for Ulcerative Colitis.

BACKGROUND: The incidence of ulcerative colitis (UC) in the elderly population is increasing. The aim of this study was to assess the degree to which age and other factors increase the risk of developing major complications in patients undergoing elective surgery for UC. METHODS: Using the ACS-NSQIP database from 2016 to 2020, patients undergoing elective surgery for UC were divided into four categories: younger than 30, 30-49, 50-69, and 70 or older. A composite outcome was created including major complications and multivariable analysis was performed to identify factors associated with composite major complications. RESULTS: 5946 patients diagnosed with ulcerative colitis who underwent elective surgery were included in the analysis. 14.1% of all patients developed a major complication. For patients with UC, factors associated with the development of a major complication were age 50-69 (OR 1.31, P = .034), male sex (OR 1.38, P < .001), Black race (OR 1.47, P = .049), dependent status (OR 2.06, P = .028), hypoalbuminemia (OR 1.92, P < .001), preoperative steroid treatment (OR 1.27, P = .038), preoperative transfusion (OR 1.91, P < .001), open surgical approach (OR 1.44, P = .002), and partial colectomy (OR 1.51, P = .007). Specifically in patients aged 70 or older, hypoalbuminemia (OR 3.20, P < .001) and preoperative transfusion (OR 2.78, P = .019) were associated with a major complication. CONCLUSION: Age is a risk factor for the development of a major complication in UC patients undergoing elective surgery. However, it is not the only risk factor nor is it the one that increases the risk the most.

Magnetic resonance imaging accuracy in staging early and locally advanced rectal cancer.

INTRODUCTION: Magnetic Resonance Imaging (MRI) is the standard pretreatment staging in patients with rectal cancer. Accurate tumor staging is paramount to determining the appropriate treatment course for patients diagnosed with rectal cancer. The current study aims to re-evaluate the accuracy of pre-operative MRI in staging of both early and locally advanced rectal cancer following completion of neoadjuvant therapy (NAT) compared to the pathologic stage. METHODS: A retrospective review of patients treated for rectal cancer between 2015 and 2020 at a single academic institution. All patients underwent rectal cancer protocol MRIs before surgical resection. Analysis was carried out in two groups: early rectal cancer: T1/2 N0 tumors with upfront surgical resection (N = 40); and locally advanced disease: T3 or greater or N+ disease receiving NAT, with restaging MRI following NAT (n = 63). RESULTS: 103 patients were included in analysis. MRI accuracy in early tumors was 35% ICC = 0.52 (95% CI 0.25-0.71) T stage and 66% ICC = 0 (95% CI -0.24, 0.29) for 29 patients with nodal data for N stage. There was 28% understaging of T2 tumors and 34% understaging of N0 stage by MRI. Post NAT MRI had 44% accuracy ICC = 0.57 (95% CI -0.15-0.20) T stage and 60% accuracy ICC = 0.32 (95% CI 0.08-0.52) N stage. Tumor invasion was overstaged on MRI: 40% T2, 29% T3, 90% T4. Nodal inaccuracy was due to overstaging, 61% N1, 90% N2. CONCLUSIONS: In locally advanced rectal cancer MRI overstaged tumors, this could be due to the continued effect of NAT from MRI to resection. This overstaging is of little clinical significance as it doesn't alter the treatment plan, except in cases of complete clinical response. In early rectal cancer, MRI had limited accuracy compared to pathology, understaging a quarter of patients who would benefit from NAT before surgery. Other adjunct imaging modalities should be considered to improve accuracy in staging early rectal cancer and consideration of complete response and enrollment in watch and wait protocols.

Perioperative use of NSAIDs and the risk of short-term endoscopic recurrence in Crohn's disease patients: A retrospective cohort study.

BACKGROUND: More evidence is needed on the use of NSAID based postoperative pain regimens for Crohn's disease (CD) and its association with recurrence. Our goal is to assess the impact of perioperative use of NSAIDs on endoscopic disease recurrence in patients with CD. METHODS: A retrospective cohort study was conducted. The primary outcome measured was endoscopic disease recurrence within 24 months of surgery, defined as a Rutgeerts score ≥ i2. RESULTS: We identified 107 patients with CD that underwent index ileocolectomy with primary anastomosis between January 2009 and July 2019. Endoscopic disease recurrence was identified in 28 (26.2%) and clinical recurrence in 18 (16.8%) patients. Exposure to NSAIDs did not increase 24-month endoscopic recurrence risk (22.2% vs. 38.5% patients, p = 0.12). CONCLUSION: In patients with CD undergoing elective ileocolic resection and primary ileocolic anastomosis, NSAID use in the perioperative period did not impact endoscopic or clinical disease recurrence rate.

Are IBD Patients Underscored when Determining Postoperative VTE Risk?

BACKGROUND: Patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolism (VTE) following colorectal surgery and there is currently no consensus on post-surgical VTE prevention or specific VTE risk assessment tools. We sought to evaluate VTE risk after colorectal surgery and determine if known risk factors used in risk assessment tools adequate correlate with VTE risk in IBD patients. METHODS: Retrospective cohort study using the National Surgical Quality Improvement Project (NSQIP) Participant User File from 2010 to 2018. RESULTS: A total of 27,679 patients were included; 19,015 (68.7%) had Crohn's disease (CD) and 8664 (31.3%) ulcerative colitis (UC). Of these, 16,749 (60.5%) underwent abdominopelvic procedures, 10,178 (36.8%) complex pelvic procedures, and 752 (2.7%) small bowel operations. The overall VTE rate was 2.3%. The VTE rate in patients with CD and UC was 1.8% and 3.6% (p < 0.001) respectively. Overall median time to VTE was 9 days after surgery. VTE rate was highest in patients who underwent complex pelvic procedures (3.6%; 361/10,178). A risk score was calculated using 16/40 available variables from the Caprini VTE Risk Assessment tool; risk score ranged from 3 to 12 points. Most patients that developed a VTE had a score between 3 and 5 points (75.6%), and only 24.5% had a score of 6 or higher. Patients with higher risk scores did not have a higher VTE incidence. CONCLUSION: Post-surgical VTE rates are high in IBD patients. Over half of the events occurred following discharge and in patients with an apparent low-risk score. Additional studies are warranted to define a recommended postoperative VTE prophylaxis regimen for patients with IBD.

Evaluation of Racial/Ethnic Disparities in the Surgical Management of Inflammatory Bowel Disease.

BACKGROUND: Disparities in managing inflammatory bowel disease (IBD) are multifactorial and occur at all stages of treatment, including surgical management. We aim to evaluate postoperative morbidity after abdominopelvic surgery among different racial/ethnic groups after surgical management of CD and UC and account for preoperative characteristics that may impact outcomes. METHODS: Patients were identified using the National Surgical Quality Improvement Project (NSQIP) file and merged with the targeted proctectomy (2016-2019) and colectomy file (2012-2019). All patients undergoing elective surgical management for ICD9/10 codes for CD and UC were included. The primary outcome was composite postoperative morbidity (CPM), a metric that identifies postoperative morbidity with available variables. Multivariable logistic regression modeling was performed to test the association between race/ethnicity and other risk factors with CPM. Postoperative outcomes were evaluated using propensity score modeling with 1:1 matching without replacement as a secondary analysis. RESULTS: In both CD and UC, CPM was highest for Black patients with 27.5% (326) and 26.1% (81), respectively. Followed by Hispanic patients with a CPM of 21.1% (73) after surgery for CD (p < 0.001) and 21.2% (31) for Asian patients after resection for UC (p = 0.005). After regression modeling, we found increased odds of CPM for Black patients after surgery for UC (OR 1.48, p = 0.013) and CD (OR 1.17, p < 0.001). Following propensity score matching (PSM), stoma creation rates were higher in Asian (10.4%, p = 0.010) and Hispanic patients (11.9%, p = 0.030) undergoing surgery for CD. CONCLUSIONS: Black patients are at increased risk of morbidity after surgery for both UC and CD. Increased morbidity in an already vulnerable population warrants targeted interventions, specifically focusing on faster access to specialized care, preoperative optimization, and culturally competent discussions on the benefits of MIS approaches are warranted in order to improve postoperative outcomes.

Disparities in industry funding among Colorectal Surgeons: a cross-sectional study.

BACKGROUND: Health Industry and physician collaboration generates innovation. Colorectal Surgeon (CRS) selection to collaborate might not be random. We aim to identify CRS personal and professional characteristics that facilitate collaboration with the Industry. METHOD: Cross-sectional study of Industry payments to CRS (2014-2018) using Open Payments Database from Centers for Medicare & Medicaid Services. Multivariable regression compared variables predicting payment amount including gender, years in practice, leadership positions, H-index, Twitter presence and geographic location. RESULTS: Surgeons who were male received 3.1 times the amount in Industry payments as compared to females (p = 0.014). Chairs and Division Chiefs received 2.7 times the amount in payments as compared to those without these leadership positions (p = 0.003). Surgeons with an H-index ≥ 8 received 2.2 times the amount in payments as compared to those with H-index < 8 (p = 0.001). Surgeons in practice for 12-19 and 20-30 years received 3 times and 4.4 times the amount in payments as compared to surgeons in practice for 1-11 years (p = 0.036 and p = 0.017, respectively). Surgeons in the South received 3.2 times and 2 times the amount in payments as compared to surgeons in the Northeast (p < 0.0005) and in the Midwest (p = 0.006). Surgeons with Twitter accounts received 1.7 times the amount in payments as compared to surgeons without Twitter (p = 0.036). Among Twitter users, those with 321-17,200 followers received 4.7 times and 9.5 times the amount in payments as compared to those with 0-15 and 16-79 followers, respectively (p = 0.008 and p = 0.009). CONCLUSION: Industry payments are more commonly addressed to male, senior surgeons in leadership tracks with strong social media outreach. With the increasing gender and racial variety in the CRS field, it is expected that collaborations between industry and surgeons will become more diverse and inclusive.

Single Center Experience with Umbilical Stomas Following Colorectal Surgery.

Background: The umbilicus is commonly used as an access site to perform minimally invasive colorectal surgery. Umbilical stomas are becoming an attractive option as an alternative site for temporary stomas since they reduce the need for additional abdominal incisions. Methods: We retrospectively evaluated patients who underwent umbilical stoma creation after colorectal resection for diagnosis of rectal cancer, diverticulitis, or ulcerative colitis between January 2020 and July 2021. Surgical technique, clinical and perioperative outcomes, complications, and cosmetic end results were described. Results: A total of 11 patients underwent umbilical stoma creation. There were no major surgical complications. Peristomal skin irritation was secondary to difficulties with the management of the pouching system. One patient presented with ostomy prolapse. Three patients experienced incisional hernia after stoma reversal. There were no wound infections. Conclusion: Umbilical stomas appear to be a safe alternative to conventional stomas and provide superior cosmetic outcomes.

Clash of the -itises: An Unexpected Case of Sigmoid Colon Vasculitis.

Vasculitis is an inflammatory process of the blood vessels, characterized by leukocyte infiltration in the vessel wall and reactive damage to the mural structures. They have a wide clinical spectrum and can present in a localized or systemic manner. Colonic involvement primarily manifests as abdominal pain and rectal bleeding. Less commonly, it can be associated with colonic perforation or anastomotic leakage after colorectal surgery. We report a case of a 42-year-old man with a history of HIV and proctocolitis who presented with an unexpected vasculitis of the sigmoid colon.
