    Abstract:
    PURPOSE: Laparoscopy is the preferred approach to elective surgery for diverticulitis and is increasingly common in the emergent setting. Although diverticulitis is most prevalent among older adults, little is known about the safety of laparoscopy for elderly patients with diverticulitis. This study aims to compare 30-day outcomes of a laparoscopic versus open approach for diverticulitis among elderly patients undergoing elective and urgent/emergent surgery. METHODS: Patients ≥ 65 years who underwent surgery for diverticulitis from 2015 to 2019 were identified from the ACS-NSQIP database. Elective and non-elective groups were analyzed separately. Coarsened exact matching matched laparoscopic and open patients 1:1 based on preoperative factors to minimize selection bias by creating comparable cohorts. Short-term outcomes of laparoscopic versus open surgery were compared. RESULTS: A total of 15,316 patients were included, 69.2% female and 88% White, with a mean age of 72.7 ± 6.1 years. Approximately half (50.9%) of cases were laparoscopic and 60.6% were elective. After matching, laparoscopy was associated with lower 30-day morbidity in both the elective (OR, 0.47; 95%CI, 0.38-0.58) and non-elective (OR, 0.76; 95%CI, 0.58-0.98) cohorts. Laparoscopic surgery in both cohorts was associated with fewer surgical site infections (SSIs) (elective, OR 0.43; 95%CI, 0.33-0.57; non-elective, OR, 0.66; 95%CI, 0.44-0.98) and shorter length of stay (LOS) (elective, mean difference, 1.7 days; 95%CI, 1.5-1.9; non-elective, mean difference, 1.2 days; 95%CI, 0.43-2.1). CONCLUSION: Elderly patients undergoing both elective and non-elective laparoscopic surgery for diverticulitis have less 30-day morbidity, SSIs, and shorter LOS compared to an open approach. Therefore, laparoscopy for elderly patients is safe in elective surgery and in select emergent cases as well.
