  • Article: Laparoscopic Removal of Poor Outcome Gastric Banding with Concomitant Sleeve Gastrectomy.
    [show abstract] [hide abstract]
    ABSTRACT: BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) has a significant incidence of long-term failure, which may require an alternative revisional bariatric procedure to remediate. Unfortunately, there is few data pinpointing which specific revisional procedure most effectively addresses failed gastric banding. Recently, it has been observed that laparoscopic sleeve gastrectomy (LSG) is a promising primary bariatric procedure; however, its use as a revisional procedure has been limited. This study aims to evaluate the safety and efficacy of LSG performed concomitantly with removal of a poor-outcome LAGB. METHODS: A retrospective review was performed on patients who underwent LAGB removal with concomitant LSG at King Saud University in Saudi Arabia between September 2007 and April 2012. Patient body mass index (BMI), percentage of excess weight loss (%EWL), duration of operation, length of hospital stay, complications after LSG, and indications for revisional surgery were all reviewed and compared to those of patients who underwent LSG as a primary procedure. RESULTS: Fifty-six patients (70 % female) underwent conversion of LAGB to LSG concomitantly, and 128 (66 % female) patients underwent primary LSG surgery. The revisional and primary LSG patients had similar preoperative ages (mean age 33.5 ± 10.7 vs. 33.6 ± 9.0 years, respectively; p = 0.43). However, revisional patients had a significantly lower BMI at the time of surgery (44.4 ± 7.0 kg/m2 vs. 47.9 ± 8.2; p < 0.01). Absolute BMI postoperative reduction at 24 months was 14.33 points in the revision group and 18.98 points in the primary LSG group; similar %EWL was achieved by both groups at 24 months postoperatively (80.1 vs. 84.6 %). Complications appeared in two (5.5 %) revisional patients and in nine (7.0 %) primary LSG patients. No mortalities occurred in either group. CONCLUSIONS: Conversion of LAGB by means of concomitant LSG is a safe and efficient procedure and achieves similar outcomes as primary LSG surgery alone.

  • Article: Laparoscopic sleeve gastrectomy in adult and pediatric obese patients: a comparative study.
    [show abstract] [hide abstract]
    ABSTRACT: Laparoscopic sleeve gastrectomy (LSG) is a recent bariatric procedure that has gained widespread popularity in morbidly obese adults. However, pediatric bariatric surgery is controversial, and the type(s) of bariatric surgery that are suitable for children and adolescents is under debate. No studies exit that compare LSG outcomes in adult and pediatric patients. We reviewed our experience to assess the safety, efficacy, and complications of LSG in adult and pediatric morbidly obese patients. A retrospective review of all patients who underwent LSG by a single surgeon between March 2008 and February 2011 was performed. The 222 patients included 108 pediatric patients aged 21 years or younger and 114 adult patients older than 21 years. Baseline, operative, perioperative, and available follow-up data were abstracted. Pediatric patients had a mean age of 13.9 ± 4.3 years and a mean baseline body mass index (BMI) of 49.6 kg/m(2), whereas adults had a mean age of 32.2 ± 9.4 years and a mean baseline BMI of 48.3 kg/m(2). Our pediatric group achieved a mean percent of excess weight loss (%EWL) of 32.4, 52.1, 65.8, and 64.9 % at 3, 6, 12, and 24 months postoperative, respectively, compared with a mean %EWL of 30.9, 55.2, 68.5, and 69.7 %, respectively, in our adult group (p > 0.05). During the 24-month follow-up period, pediatric patients attended 71.7 % of follow-up visits, whereas adults attended 61.2 % of follow-up visits (p = 0.01). Postoperative complications occurred in six (5.6 %) and eight (7 %) pediatric and adult patients, respectively. Laparoscopic sleeve gastrectomy in the pediatric age group is of similar safety and effectiveness compared with adults. Pediatric patients had fewer major complications and were more compliant with follow-up than adults. Nevertheless, long-term results are required to further clarify the safety and effectiveness of LSG in pediatric patients.

  • Article: Laparoscopic sleeve gastrectomy in 108 obese children and adolescents aged 5 to 21 years.
    [show abstract] [hide abstract]
    ABSTRACT: To report experience with laparoscopic sleeve gastrectomy (LSG) in 108 severely obese children and adolescents. Obesity during childhood and adolescence can be accompanied by serious long-term adverse health and longevity outcomes. With increased use of bariatric surgery to treat obesity in these patients, diverse guidelines have been published, most of which exclude children aged younger than 14 years. Few reports describe LSG in children and adolescents, delaying determining its safety and effectiveness and developing guidance regarding its use. A retrospective review of LSG performed from March 2008 through February 2011 by a single surgeon at King Saud University Hospitals, Riyadh, Saudi Arabia, included 108 patients aged 5 through 21 years. Patients attending follow-up visits at 3 (n = 88), 6 (n = 76), 12 (n = 41), and 24 (n = 8) months postoperatively experienced median excess weight loss (EWL) of 28.9%, 48.1%, 61.3%, and 62.3%, respectively. At 6 and 12 months follow-up, 42.1% (n = 32) and 73.2% (n = 30) of patients achieved at least 50% EWL, whereas 7.9% (n = 6) and 4.9% (n = 2) had 25% or less EWL, respectively. There were no serious postoperative complications and no adverse sequelae developed during the current follow-up. Available comorbidity data indicate resolution of dyslipidemia, 21 of 30 (70.0%); hypertension, 27 of 36 (75.0%); prehypertension, 15 of 18 (83.3%); symptoms of obstructive sleep apnea, 20 of 22 (90.9%); diabetes, 15 of 16 (93.8%); and prediabetes, 11 of 11 (100.0%). LSG resulted in successful short-term weight loss in more than 90% of pediatric patients and 70% or more comorbidity resolution during up to 24 months of follow-up. Long-term data are necessary to evaluate persistence of weight loss and maturation to adulthood.
