Safety and effectiveness of LAP-BAND AP System: results of Helping Evaluate Reduction in Obesity (HERO) prospective registry study at 1 year.

Background: Laparoscopic adjustable gastric banding has several distinctive features, including band adjustability, easy reversibility, and lack of malabsorption, which contribute to its widespread use. The LAP-BAND AP System (LBAP; Allergan, Inc.), a redesigned and improved version of the original device, was approved by the US Food and Drug Administration in 2006.

Five-year weight loss experience of outpatients receiving laparoscopic adjustable gastric band surgery.

Background: This study evaluated the efficacy and safety of laparoscopic adjustable gastric banding (LAGB) in a large cohort of morbidly obese patients followed for up to 5 years.

Methods: Morbidly obese patients, ≥ 16 years of age, who underwent LAGB surgery at the Surgical Weight Loss Clinic in Ontario, Canada, between May 2005 and January 2011 were eligible for this retrospective chart review. Electronic files were searched to identify all patients who met the inclusion/exclusion criteria.

Risk of gastric pouch enlargement with adjustable gastric banding in premenopausal women: sex hormones may play a role.

Objective: To examine the influence of age and gender on the development of proximal gastric pouch distension (PPD) after laparoscopic adjustable gastric banding (LAGB) surgery.

Background: PPD is the most common reason for revision with adjustable gastric banding surgery. Maintaining the anatomical integrity of bariatric surgery is a key to long-term success.

Exploration of esophageal hiatus: does crural repair reduce proximal pouch distension?

Background: Repair of a hiatal hernia during laparoscopic adjustable gastric banding is advisable; however, the practice of more active esophageal hiatus exploration and repair has been promoted with an expectation of reducing proximal gastric pouch distension (PPD). Our objective was to explore the relationship between crural exploration and repair (CR) and PPD in a private practice in Canada.

Methods: The data from 3000 consecutive patients who underwent primary laparoscopic adjustable banding procedures at a single center from February 2005 to May 2011 were examined.
