Brief summary

Obesity is a extremely widespread condition in Europe and North America, burdened by a series of complications characterized by major morbidity and morbility. In recent years, bariatric surgery has progressively assumed a leading role in the treatment of morbid obesity and restrictive bariatric surgery procedures, such as laparoscopic vertical sleeve gastrectomy are common. The aim of the study is to retrospectively determine the value of postoperative CT after LSG as an early tool to identify risk factors for the subsequent development of gastric fistula and enable to stratify postoperative risk in asymptomatic patients and ensure effective management of these risk factors.

Design outcomes

Primary

Measure	Time frame	Description
Value of Post surgery CT in identifying risks for subsequent development of gastric fistula	72 hours post LSG	Measurements of: presence or abscence of fistula and site; presence/abscence of hematoma and site; presence/abscence of gastric torsion; Stapler to pylorus distance and stapler length

Secondary

Measure	Time frame	Description
Post surgery risk	72 hours post LSG	Risk stratification based on the correlation of the measurements obtained from the primary objective on outcome (complication vs non complication).
