Revisional bariatric surgery at a single institution

Area of Science:

• Bariatric Surgery
• Surgical Complications
• Revision Procedures

Background:

• Bariatric surgery, while generally safe, can lead to long-term complications necessitating revisional surgery.
• Understanding the spectrum of primary procedures, revision indications, and strategies is crucial for patient management.

Purpose of the Study:

• To illustrate the spectrum of primary bariatric procedures and their associated complications.
• To analyze the indications and strategies employed for revisional bariatric surgery.
• To evaluate the effectiveness of revisional bariatric surgery in terms of excess weight loss (EWL) and complications.

Main Methods:

• A retrospective chart review was conducted.
• Sixty-three patients undergoing revisional bariatric surgery were identified and analyzed.
• Data collected included primary procedure, revision procedure, complications, and percentage of excess weight loss (EWL).

Main Results:

• Common primary procedures included vertical banded gastroplasty (VBG), Roux-en-Y gastric bypass (RYGB), and laparoscopic adjustable gastric banding (LAGB).
• Revisions primarily involved conversion to RYGB or further RYGB/LAGB procedures.
• The overall morbidity rate was 30% (major morbidity 11%), with no mortalities. EWL varied significantly based on the type of revision, with conversions from VBG to RYGB showing a mean EWL of 50%.

Conclusions:

• Revisional bariatric surgery is an effective approach for managing complications from primary procedures.
• Complication rates for revisional surgery are higher compared to primary bariatric procedures.
• The selection of both the initial and revisional surgical procedures critically influences the achievement of excess weight loss.
