This study aimed to assess intra- and postoperative outcomes of robotic resection of left-sided complicated diverticular disease. Retrospective analysis of a prospectively maintained institutional database on consecutive patients undergoing elective robotic resection for diverticular disease (2014-2018). All procedures were performed within an enhanced recovery pathway (ERP). Demographic, surgical and ERP-related items were compared between patients with simple and complicated diverticular disease according to intra-operative presentation. Postoperative complications and length of stay were compared between the two groups. Out of 150 patients, 78 (52%) presented with complicated and the remaining 72 (48%) with uncomplicated disease. Both groups were comparable regarding demographic baseline characteristics and overall ERP compliance. Surgery for complicated disease was longer (288 ± 96 vs. 258 ± 72 min, p = 0.04) and more contaminated (≥ class 3: 57.7 vs. 23.6%, p < 0.001) with a trend to higher conversion rates (10.3 vs. 2.8%, p = 0.1). While postoperative overall complications tended to occur more often after resections for complicated disease (28.2 vs. 15.3%, p = 0.075), major, surgical and medical complications did not differ between the two groups, and median length of stay was 3 days in both settings (p = 0.19). Robotic resection of diverticular disease was feasible and safe regardless of disease presentation by the time of surgery. [ABSTRACT FROM AUTHOR]

Purpose: Enhanced recovery after surgery (ERAS) protocols advocate no nasogastric tubes after colorectal surgery, but postoperative ileus (POI) remains a challenging clinical reality. The aim of this study was to assess incidence and risk factors of POI. Methods: This retrospective analysis included all consecutive colorectal surgical procedures since May 2011 until November 2014. Uni- and multivariate risk factors for POI were identified by multiple logistic regression and functional and surgical outcomes assessed. Results: The study cohort consisted of 513 consecutive colorectal ERAS patients. One hundred twenty-eight patients (24.7%) needed postoperative reinsertion of nasogastric tube at the 3.9 ± 2.9 postoperative day. Multivariate analysis retained the American Society of Anesthesiologists group 3-4 (odds ratio (OR) 1.3; 95% CI 1-1.8, p = 0.043) and duration of surgery of >3 h (OR 1.3; 95% CI 1-1.7, p = 0.047) as independent risk factors for POI. Minimally invasive surgery (OR 0.6; 95% CI 0.5-0.8, p ≤ 0.001) and overall compliance of >70% to the ERAS protocol (OR 0.7; 95% CI 0.6-1, p = 0.031) represented independent protective factors. POI was associated with respiratory (23 vs. 5%, p ≤ 0.001) and cardiovascular (16 vs. 3%, p ≤ 0.001) complications. Conclusions: POI was frequent in the present study. Overall compliance to the ERAS protocol and minimally invasive surgery helped to prevent POI, which was significantly correlated with medical complications. [ABSTRACT FROM AUTHOR]
