Adjustable gastric banding: 5-year experience.
ABSTRACT From 1993 to 1999, 172 patients underwent adjustable silicone gastric banding (ASGB) or laparoscopic adjustable silicone gastric banding (LASGB). In 109 patients the adjustable band was placed via laparoscopy; in the other patients it was placed via laparotomy (prelaparoscopic era, conversions from other bariatric operations, conversions for laparoscopic failure). The conversion rate from laparoscopy to laparotomy was 9.3%, occurring in the early part of our experience.
Mean age was 37.9 years, weight 135 +/- 14.8 kg (82-218) and BMI 46.3 +/- 5.4 (35.1-69.5). All patients had multiple band adjustments, temporary antisecretive, electrolyte and vitamin therapy, and follow-up per routine.
Weight loss at 3 years was 30.2%; mean percent loss of excess weight was 62.5%. There was no mortality. The most important technical complications were: gastric pouch dilatation that required band replacement or removal (5.8 %); mild gastric pouch dilatation reversible with adequate dietary and pharmacological treatment (4.6%); intraoperative gastric perforation (2.3%); band migration (0.6%). The band was removed in 2.3%, with conversion to another bariatric procedure in 1.1%.
Results have been satisfactory thus far.

ABSTRACT: Many women with polycystic ovarian syndrome (PCOS) are overweight. This study investigated the impact of weight loss surgery on the clinical manifestations of this disorder in morbidly obese women with PCOS-a major risk factor for the development of heart disease, stroke, and type II diabetes. We reviewed the outcomes of women diagnosed with PCOS who had undergone weight loss surgery at the University of Pittsburgh between July 1997 and November 2001. We evaluated the changes in menstrual cycles, hirsutism, infertility, and type II diabetes. A total of 24 women with PCOS were included in the study. Their mean age was 34 +/- 9.7 years. The mean preoperative body weight was 306 +/- 44 lb, with a body mass index of 50 +/- 7.5. All patients were oligomenorrheic. Of the 24 patients, 23 were hirsute. All women underwent elective laparoscopic gastric bypass surgery. The mean follow-up period was 27.5 +/- 16 months. The mean excess weight loss at 1 year of follow-up was 56.7% +/- 21.2%. All women resumed normal menstrual cycles after a mean of 3.4 +/- 2.1 months postoperatively. Of the 23 women with hirsutism, 12 (52%) had complete resolution at a mean follow-up of 8 +/- 2.3 months, 6 (25%) had moderate resolution at a mean of 21 +/- 18 months, and 3 had minimal resolution at 34 +/- 14 months. Two women reported no change in their hirsutism at 32 +/- 7 months. Five women were able to conceive after surgery without the use of clomiphene. Gastric bypass surgery and its consequent weight loss results in significant improvement of multiple clinical problems related to PCOS.Surgery for Obesity and Related Diseases 03/2005; 1(2):77-80.

ABSTRACT: We attempted to compare the safety and efficacy of laparoscopic adjustable gastric banding with vertical-banded gastroplasty and gastric bypass. Morbid obesity presents a serious health issue for Western countries, with a rising incidence and a strong association with increased mortality and serious comorbidities, such as diabetes, hyperlipidemia, and cardiovascular disease. Unfortunately, conservative treatment options have proven ineffective. Surgical interventions, such as vertical-banded gastroplasty (stomach stapling), Roux-en-Y gastric bypass, and, more recently, laparoscopic gastric banding have been developed with the aim of providing a laparoscopically placed device that is safe and effective in generating substantial weight loss.Methods Electronic databases were systematically searched for references relating to obesity surgery by (1) laparoscopic adjustable gastric banding (LAGB), (2) vertical banded gastroplasty (VBG), and (3) Roux-en-Y gastric bypass (RYGB).ResultsOnly 6 studies reported comparative results for laparoscopic gastric banding and other surgical procedures. One study reported comparative results for all 3 surgical procedures, and this study was only of moderate quality. In total, 64 studies were found that reported results for LAGB and 57 studies reported results on the comparative procedures. LAGB was associated with a mean short-term mortality rate of approximately 0.05% and an overall median morbidity rate of approximately 11.3%, compared with 0.50% and 23.6% for RYGB, and 0.31% and 25.7% for VBG. Overall, all 3 procedures produced considerable weight loss in patients up to 4 years in the case of LAGB (the maximum follow-up available at the time of the review), and more than 10 years in the case of the comparator procedures.Conclusions The Australian Safety and Efficacy Register of New Interventional Procedures–Surgical Review Group concluded that the evidence base was of average quality up to 4 years for LAGB. Laparoscopic gastric banding is safer than VBG and RYGB, in terms of short-term mortality rates. LAGB is effective, at least up to 4 years, as are the comparator procedures. Up to 2 years, LAGB results in less weight loss than RYGB; from 2 to 4 years there is no significant difference between LAGB and RYGB, but the quality of data is only moderate. The long-term efficacy of LAGB remains unproven, and evaluation by randomized controlled trials is recommended to define its merits relative to the comparator procedures.Surgery 03/2004; 135(3):326-351.

ABSTRACT: This prospective study evaluated the effectiveness and safety of laparoscopic adjustable gastric banding (LAGB) for morbid obesity. Ninety-five consecutive patients (89 female; median age 38 years, range 19 to 69) underwent LAGB for morbid obesity. Median weight and body mass index were 123.2 (88.9 to 228.6) kg and 45 (32.7-76.4) kg/m(2) respectively. Significant coexistent disease was present in 52 (55%) patients. Median excess weight loss was 53% (range 96.9% to 12.1%) and 62% (range 107.5% to 32.3%) at 1 and 2 years respectively (P <0.001). Median operative time was 90 (range 35 to 285) minutes and inpatient stay 2 (range 1 to 10) days. Early complications were seen in 17 (18%) patients most commonly nausea/vomiting or dysphagia. Late complications were seen in 25 (26.3%) patients, most frequently vomiting or reflux due to band slippage or pouch dilatation. There was 1 (1%) operative death. LAGB is an effective operation for morbid obesity that results in equivalent weight loss to open surgical procedures.The American Journal of Surgery 08/2002; 184(2):97-102.
