ABSTRACT
BACKGROUND: In the inflammatory bowel disease literature, emergency surgery for Crohn's disease (CD) is associated with worse postoperative outcomes as compared to elective surgery. Previous studies have compared heterogeneous groups only. We hypothesized that this association would be lost after matched analysis. We aimed to compare matched CD patients undergoing elective vs emergency surgery. METHODS: The National Surgical Quality Improvement database (01/2005-12/2019) was utilized to identify adult CD surgical patients. Univariate and conditional logistic regression models were used to analyze unmatched and matched cohorts. Propensity-score matching was performed to match emergency to non-emergency patients 1:1. Our primary outcome was a composite of any complication. Our secondary endpoints were hospital readmission, unplanned reoperation and 30-day morbidity and mortality. RESULTS: In the unmatched analyses (n = 12,181/95.28% elective and n = 603/4.72% emergency) of Crohn's patients undergoing colectomy, 20% of elective and 42% of emergency patients experienced a complication (p < 0.001). Over 20 outcomes measured including length of stay (LOS), readmission, infections and respiratory, cardiovascular and renal complications, were worse in the emergency cohort. In the matched analyses (n = 400 emergency/400 elective patients) only the categories of any complication (OR 1.44, 1.06-1.96 95% CI, p = 0.02), any surgical site infection (SSI, OR 1.53, 1.07-2.19 95% CI, p = 0.02), superficial SSI (OR 2.25, 1.14-4.44 95% CI, p = 0.02), organ space SSI (1.58 OR 1.04-2.4 95% CI, p = 0.03), unplanned intubation (OR 5.0, 1.45-17.27 95% CI, p = 0.01), ventilation > 48 h (OR 9.0, 1.4-38.79 95% CI, p = 0.003) and septic shock (OR 4.5, 1.86-10.9 95% CI, p < 0.001) were higher in the emergency cohort. CONCLUSIONS: Matching CD patients resulted in a loss of the observed increase in cardiovascular and renal complications, reoperation and LOS following emergency surgery; however, SSIs and respiratory complications remained increased despite matching.

AIM: As the understanding of anal dysplasia continues to develop, controversy remains regarding treatment of these lesions. The purpose of this study was to evaluate lesion type (flat vs exophytic) and the association between morphology and dysplasia. METHODS: This was a single-centre retrospective analysis of a prospectively collected pathological database of patients > 17 years old who underwent operative excision/biopsies for presumed anal condyloma or dysplasia from 2009 to 2018. The analysis includes comparisons between patient factors, phenotype and grade of dysplasia. RESULTS: Sixty-nine patients had 423 lesions. The mean age of the study population was 48.2 years. 62.3% were men and 46.4% of patients were black. 47.8% of patients were human immunodeficiency virus (HIV) positive and 39.1% were men who have sex with men (MSM). There were 176 (41.6%) flat lesions and 234 (55.3%) exophytic lesions. Exophytic lesions were 2.5-fold more likely to be associated with a higher grade of dysplasia than flat lesions (OR 2.63, 95% CI 1.09-6.32). Neither lesion type nor dysplasia severity was associated with human papillomavirus, lesion location or patient characteristics, including race, MSM or HIV status. DISCUSSION: Exophytic lesions were more than twice as likely to have advanced dysplasia compared with flat lesions. A clearer understanding of the association between gross lesion appearance and dysplasia will allow more appropriate counselling of patients and the development of better screening and treatment guidelines for anal condylomata and dysplasia.

AIM: Colonic volvulus is a common entity encountered by colorectal surgeons, but there are few reports of national data regarding postoperative outcomes. The aim of this study was to describe the volvulus population, 30-day outcomes following right- and left-sided colectomy and risk factors for postoperative complications. METHOD: The American College of Surgeons National Surgical Quality Improvement Program Database from 2012 to 2015 was utilized to identify patients with the diagnosis of 'volvulus' who underwent right- or left-sided colectomy. Primary outcomes were overall morbidity and mortality. RESULTS: A total of 2175 patients were identified (661 right colectomy and 1514 left colectomy). Risk factors for complications following right-sided colectomy included: age, male gender, smoker, systemic inflammatory response syndrome, sepsis, septic shock and American Society of Anesthesiologsts class ≥ 4. Risk factors for complications following left-sided colectomy included: age, male gender, systemic inflammatory response syndrome, sepsis and septic shock. CONCLUSION: Several nonmodifiable risk factors were identified for complications following colectomy for volvulus. These risk factors can be used in patient/family counselling and discharge planning.

AIM: Conversion rates from laparoscopic to open colectomy and associated factors are traditionally reported in clinical trials or reviews of outcomes from experienced institutions. Indications and selection criteria for laparoscopic colectomy may be more narrowly defined in these circumstances. With the increased adoption of laparoscopy, conversion rates using national data need to be closely examined. The purpose of this study was to use data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to identify factors associated with conversion of laparoscopic to open colectomy at a national scale in the United States. METHOD: The ACS-NSQIP Participant Use Data Files for 2006-2011 were used to identify patients who had undergone laparoscopic colectomy. Converted cases were identified using open colectomy as the primary procedure and laparoscopic colectomy as 'other procedure'. Preoperative variables were identified and statistics were calculated using sas version 9.3. Logistic regression was used to model the multivariate relationship between patient variables and conversion status. RESULTS: Laparoscopy was successfully performed in 41 585 patients, of whom 2508 (5.8%) required conversion to an open procedure. On univariate analysis the following factors were significant: age, body mass index (BMI), American Society of Anesthesiologists (ASA) class, presence of diabetes, smoking, chronic obstructive pulmonary disease, ascites, stroke, weight loss and chemotherapy (P < 0.05). The following factors remained significant on multivariate analysis: age, BMI, ASA class, smoking, ascites and weight loss. CONCLUSION: Multiple significant factors for conversion from laparoscopic to open colectomy were identified. A novel finding was the increased risk of conversion for underweight patients. As laparoscopic colectomy is become increasingly utilized, factors predictive of conversion to open procedures should be sought via large national cohorts.
