Does laparoscopic gastric banding create hiatal hernias?

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Surgical Complications

Background:

• Laparoscopic adjustable gastric band (LAGB) is a bariatric procedure.
• The development of hiatal hernias (HH) after LAGB is not well-established.
• This study investigates HH development post-LAGB.

Purpose of the Study:

• To determine the incidence of hiatal hernias (HH) developing after laparoscopic adjustable gastric band (LAGB) placement.
• To assess the clinical presentation and diagnostic challenges of post-LAGB HHs.

Main Methods:

• Retrospective review of a bariatric surgical database.
• Identification of patients without pre-existing HH who later required HH repair.
• Analysis of patient presentation and surgical findings.

Main Results:

• Twelve of 695 LAGB patients (1.72%) developed HH requiring repair.
• Patients presented with symptoms 18 months post-LAGB.
• Hiatal hernias were often detected during revision surgery despite negative preoperative imaging.

Conclusions:

• A significant incidence of HH develops after LAGB in patients without initial evidence of HH.
• Persistent dysphagia post-LAGB may suggest an undiagnosed HH.
• Careful intraoperative inspection of the hiatus is crucial during revision surgery for LAGB complications.
