Laparoscopic Sleeve Gastrectomy: A Radiological Guide to Common Postsurgical Failure

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Radiology

Background:

• Laparoscopic sleeve gastrectomy (LSG) is a prevalent bariatric procedure globally.
• LSG is favored for its low complication rates, effective comorbidity resolution, and significant weight loss.
• Radiological assessment is crucial for evaluating LSG outcomes and complications.

Purpose of the Study:

• To review the surgical technique of LSG.
• To describe the expected post-operative imaging appearance after LSG.
• To detail the imaging findings associated with common complications following LSG.

Main Methods:

• Review of surgical techniques for LSG.
• Analysis of post-operative imaging studies (e.g., CT, MRI, fluoroscopy).
• Correlation of imaging findings with clinical outcomes and known complications.

Main Results:

• Detailed description of the LSG surgical steps and resulting anatomy.
• Identification of typical post-operative imaging features.
• Characterization of imaging signs of complications such as leaks, strictures, and bleeding.

Conclusions:

• Understanding LSG technique and normal post-operative anatomy is essential for accurate imaging interpretation.
• Radiology plays a key role in diagnosing insufficient weight loss, weight regain, and complications after LSG.
• This review provides a guide for radiologists and surgeons managing patients undergoing LSG.
