Background: CT may be performed after laparoscopic sleeve gastrectomy to assess for abscesses, perforation, staple line dehiscence, and other complications such as splenic injury or infarction. Objectives: The aim of the study was to evaluate the value of multidetector CT in the evaluation of the suspected complications of laparoscopic sleeve gastrectomy (LSG). Subjects & methods: This pilot study was designed as an observational cohort study, included 240 who underwent LSG and CT was done for 30 patients with clinically or radiologically suspected complication even in the presence of negative UGI series. Results: CT detects complication in 11 patients out of the 30 patients (36.7%), with no mortality. Leakage occurred in 10%, abscess in 3.3%, hematoma in 10%, splenic infarction and portal vein (PV) thrombosis in 6.7% respectively. Conclusions: As LSG is performed increasingly and frequently, it is essential for radiologists to recognize the normal postoperative anatomy and identify the complications of this procedure. CT is an important imaging tool to diagnose suspected complications of laparoscopic sleeve gastrectomy procedure to ensure accurate diagnosis.
