Introduction: Colorectal cancer (CRC) is the third most common cancer and the second leading cause of death worldwide, with an incidence of 10.2%. The treatment of CRC has evolved over the past 25 years. Two surgical procedures are used: abdominoperineal resection (APR) and low anterior resection (LAR) and ultra-low anterior resection (ULAR). The recurrence rate and quality of life are similar between these approaches. Objective: To compare the quality of life of rectal cancer patients treated with abdominoperineal resection versus conservative sphincter-preserving surgeries: low anterior resection (LAR) and ultra-low anterior resection (ULAR) at UMAE of Puebla. Methods: A comparative, observational, cross-sectional study was conducted on CRC patients treated between 2015 and 2019 at a tertiary-level hospital in Puebla. Two groups were formed: those managed with APR and those manage...

Due to multiple transfusions and hospitalizations, surgery was scheduled. Two duodenal diverticula and multiple diverticula were found in the jejunum. Duodenal diverticulectomies and segmental resection of the jejunum with entero-entero anastomosis were performed. During the post-surgery period she presented intestinal fistula, which was resolved with mixed nutrition. Discussion: Intestinal transit revealed diverticula as a probable cause of bleeding. Since there were no minimally invasive options a...
