[Short-Term Outcomes of Intracorporeal versus Extracorporeal Anastomosis for Minimally Invasive Right Colectomy in Elderly Patients-A Propensity Score-Matched Study].

Previous studies have shown that intracorporeal anastomosis(IA)improves postoperative recovery. However, its short-term outcomes remain controversial in elderly patients. This study aimed to compare the short-term outcomes of IA versus extracorporeal anastomosis(EA)for minimally invasive right colectomy in elderly patients aged 80 years or older using a propensity score matching(PSM)analysis based on double centric cohort of patients with right colon cancer between April, 2020, and December, 2024. Initially, 97 patients were selected, including 49 IA patients. After PSM, 64 patients were compared. There was no statistically significant difference between IA and EA in terms of operative time and postoperative morbidity (6.2% in IA vs 12.5% in EA;p=0.67). The IA group had a longer resected distal margin length(130 vs 100 mm, p=0.04) and shorter length of stay(7.5 vs 10 days, p=0.02). This comparison shows several clinical outcomes advantages for the IA in minimally invasive right colectomy in elderly patients.
