The length of stay (LOS) of a surgical procedure is influenced both by the real need for medical and nursing care of the patient and also by the practice style of each unit, which can include unjustified stays. The aim of this work was to estimate the appropriate LOS for appendectomy and its differences with the LOS observed in practice. Two hundred and forty-nine medical records (249 admission days and 1447 successive stays) for patients over 6 years old who had had an appendectomy in 1992 were classified by Diagnosis Related Groups (DRG) and reviewed using the Appropriateness Evaluation Protocol. 1.6% of admission days and 31.7% of successive stays were assessed inappropriate. The appropriate LOS for appendectomy was 4.7 days as opposed to 6.8 days of observed LOS. For the DRG 167 (76.3% of the sample) appropriate LOS was 3.4 days (observed LOS 4.9 days). These results suggest the existence of an important proportion of avoidable hospital stays and provides a simple and low cost methodology for assessing the suitability of local hospitalization practices.

Purpose Obesity is associated with recurrence of complex incisional hernia repair (CIHR). Bariatric procedure during CIHR can improve recurrence rates without increasing morbidity. This study aimed to describe our results after CIHR in patients with obesity, in which a simultaneous bariatric procedure was performed. Materials and Methods We performed a retrospective observational study including patients who underwent surgery between January 2014 and December 2018, with a complex incisional hernia (CIH) according to the Slater classification and body mass index (BMI) ≥35. CIHR was the main indication for surgery. We collected demographic data, comorbidities, CIH classification according to the European Hernia Society, type of bariatric procedure, postoperative morbidity using the Dindo-Clavien classification, and short-term results. Computed tomography (CT) is performed preoperatively. Results Ten patients were included in the study (7 women). The mean BMI was 43.63±4.91 kg/m 2 . The size of the abdominal wall defect on CT was 8.86±3.93 cm. According to the European Hernia Society classification, all CIHs were W2 or higher. Prosthetic repair of the CIH was selected. Onlay, sublay, preperitoneal, and inlay mesh placement were performed twice each, as well as one modified component separation technique and one transversus abdominis release. Gastric leak after sleeve gastrectomy was the only major complication. Short-term outcomes included one recurrence, and % total weight loss was 24.04±8.03 after 1-year follow-up. Conclusion The association of bariatric procedures during CIHR seems to be feasible, safe, and could be an option for surgical treatment in selected patients.
