Abstract

Title: Evaluating Outcomes of Elective Robotic-Assisted Colonic Resection for Complicated and non-Complicated Diverticulitis at a Single Institution.

Authors: Skancke M, Alalwan A, Obias V

Institution: Department of Colon and Rectal Surgery at the George Washington University Hospital

Purpose/Background:

With the incidence of diverticulitis rising, an increasing number of patients are presenting with complicated disease. This analysis compares the outcomes of robotic surgery for elective colonic resection for uncomplicated and complicated diverticulitis at a single institution.

Methods/Interventions:

Clinical data from a single institution between 2009 and 2016 was reviewed for robotic assisted cases performed by single colorectal surgeon proficient in robotic surgery. Patients were stratified whether they were diagnosed with diverticulitis versus diverticulitis with stricture, abscess or fistula. Univariate analysis was used to identify differences in intra and postoperative outcomes.

Results/Outcomes:

The inclusion criteria identified 97 cases during the time of review, of which 27 (27.8%) had a concomitant stricture, fistula or prior abscess. Patients in both cohorts were equally matched regarding preoperative demographics (age, gender, body mass index) and comorbidities (diabetes, hypertension, COPD, heart disease). Total operative time was significantly longer for patients with complicated diverticulitis (325 vs. 227 minutes, p<0.001) as was intraoperative blood loss (390cc vs. 176cc, p=0.013). While the rate of intraoperative conversion (33% vs. 24%, p=0.372) and postoperative complications (7% vs.3%, p=0.317) was higher for the complicated group, the differences were not significant. Postoperative length of stay was higher for patients with complicated diverticulitis (5.26 days vs. 4.11 days, p=0.018) but there were no significant differences in the rates of readmission or reintervention following robotic surgery.

Conclusion/Discussion:

Robotic surgery does not have a significantly higher rate of postoperative complication for advanced diverticular disease and should be considered when patients present with prior attacks complicated by abscess, stricture or fistula.
