Most patients with colon cancer (CC) are diagnosed and treated electively. However, a fifth of them will de- but as an emergency (obstruction or perforation). The aim of this study was to determine postoperative morbidity (POM) and overall survival (OS) in patients resected by perforated CC (PCC). Retrospective case series of patients with PCC undergoing colectomy and lymphadenectomy, consecutively, at RedSalud Mayor Clinic and Temuco hospital, Chile, between 2010 and 2019. The outcome va- riable were POM and OS. Other variables of interest were surgical time, resectability, number of resected lymph nodes, hospital stay, mortality, recurrence, and disease-free survival (DFS). Patients were followed clinically. Descriptive statistics was used (measures of cen- tral tendency and dispersion), and OS analysis was applying Kaplan Meier curves.15 patients (60 % women) were intervened, with a median age of 62 years. The most frequent location was the sigmoid colon (6 cases, 40.0 %). Resectability of the series was 100 %. Me- dian surgical time, number of lymph nodes resected, and hospital stay; they were 80 min, 20 and 5 days respectively. POM was 26.7 % (4 cases). With a median follow-up of 36 months, recurrence was 40.0 %. On the other hand, OS and DFS at 5 years were 46.7 % and 33.3 %, respectively. The observed results, in terms of POM and OS, were like international series.
