Purpose: Mini-gastric bypass (MGB) is considered an alternative option in metabolic and bariatric surgery. The procedure holds promises for shorter operating times and less operative complications. The radiologist plays an important role in postoperative evaluation, especially in patients with clinical suspicion of complications. The purpose of this essay is to describe the imaging findings of MGB postoperative complications.
Methods: This study is a retrospective analysis of all patients who underwent MGB between the years 2015 and 2019 in Tel Aviv Sourasky Medical Center. Patients` imaging (abdominal computed tomography, CT) were evaluated for complications. Patients` demographics, comorbidities, operative and postoperative data were collected from electronic medical records.
Results: Between the years 2015-2019, 464 patients underwent MGB surgery. Out of which 66 patients underwent abdominal CT scan postoperatively. In 24/66 (36.4%) complication were identified radiologically. The main complications included intraperitoneal fluid collections (9/24, 37.5%), Intraperitoneal hematomas (6/24, 25%), leaks (2/24, 8.3%), abscess (1/24, 4.2%), small bowel obstructions (1/24, 4.2%), spleen lacerations (1/24, 4.2%), abdominal wall hematomas (2/24, 8.3%) and colitis (2/24,8.3%).
Conclusion: Post operative abdominal CT is an important tool following MGB surgery, with more than a third of positive findings. With the increasing prevalence of this procedure, radiologists need to be familiar with findings of postoperative MGB complications.
