Objective: To determine the standard surgical times of the four most common general surgery procedures (unilateral inguinal hernioplasty, bilateral inguinal hernioplasty, umbilical hernioplasty and cholecystectomy) in a second-level hospital and to estimate the probability of extending the time of each of the procedures. Efficiency is a widely studied subject in economics. It involves the need for fewer elements in the production of a certain level of goods and services. Therefore, it is extremely important to consider it in the field of surgery. Materials and methods: An observational, descriptive and retrospective study. It used the operating room records from 2017 to 2019 of the General Surgery service in a second-level hospital. Based on this information, the time required for each procedure was standardized using the mean for each one (umbilical hernioplasty, unilateral or bilateral...

Objective: To make a comparison between the transoral endoscopic thyroidectomy vestibular approach (TOETVA) and the conventional open approach of thyroidectomies performed at the Hospital Central del Estado de Chihuahua. Materials and methods: A retrospective study was carried out on 10 patients who underwent total or partial thyroidectomies using either an endoscopic technique or conventional open surgery between March 2018 and March 2019. The study included patient demographics (age and body mass index [BMI]), indications for surgery (tumor size by ultrasound), surgical history and comorbidities, surgical time (in hours for both open and endoscopic procedures), number of conversions required, length of hospital stay, histopathological results from intraoperative and definitive biopsies, and immediate and late postoperative complications specific to both procedures. During the TOETVA, t...
