Abstract

BACKGROUND: Right colon diverticulitis is a rare disease process for which there are no established treatment guidelines, and outcomes following surgical management are underreported in the literature. We sought to describe the demographics of patients undergoing ileocecectomy for right colon diverticulitis and compare short-term postoperative outcomes between open and minimally invasive approaches. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) was queried for patients with diverticulitis of the colon who underwent ileocecectomy between 2012 and 2019. Patients with ascites, disseminated cancer, ASA class 5, and patients requiring mechanical ventilation were excluded. Preoperative, intraoperative, and 30-day postoperative outcomes were compared between the groups using both univariable chi-square or t-tests and multivariable logistical regression models. RESULTS: 484 patients met inclusion criteria, 150 (31%) of whom underwent open surgery and 334 (69%) who underwent minimally invasive surgery with an 18% conversion rate. 71% of patients were White, 11% of were Black, 7% were Hispanic, and 5% were Asian. The indication for surgery differed significantly by approach with acute diverticulitis representing 47% of indications for open cases and 25% for MIS cases (p < 0.0001). After adjusting for possible confounders, patients undergoing the open approach had a significantly higher chance of post-operative sepsis (p = 0.009) and ileus (p = 0.04) compared with MIS. Hospital length of stay was also significantly shorter after MIS compared to open (5.9 days vs. 11.5 days; p < 0.0001). Mean operative time was significantly longer in MIS than open (173 min vs. 198 min; p = 0.001). CONCLUSION: Our analysis demonstrates that minimally invasive surgery is associated with equivalent or improved short-term morbidity and shorter hospital stay despite longer mean operative time. Interestingly, unlike other countries where the prevalence of right colon diverticulitis is higher, a minority of patients requiring operative therapy in our study of patients in the Western hemisphere were of Asian descent.
