          The aim of this study was to assess outcomes of laparoscopic sleeve gastrectomy (LSG) as a stand-alone bariatric operation according to the Bariatric Analysis and Reporting Outcome System (BAROS).


          Out of 112 patients included and operated on initially, 84 patients (F/M, 63:21) were followed up for 14–56 months (mean 22 ± 6.75). Patients lost to follow-up did not attend scheduled follow-up visits or they have withdrawn their consent. Mean age was 39 years (range 17–67; SD ± 12.09) with mean initial BMI 44.62 kg/m 2 (range 29.39–82.8; SD ± 8.17). Statistical significance was established at the p < 0.05 level.


          Mean operative time was 61 min (30–140 min) with mean hospital stay of 1.37 days (0–4; SD ± 0.77). Excellent global BAROS outcome was achieved in 13% of patients, very good in 30%, good in 34.5%, fair 9.5% and failure in 13% patients 12 months after surgery. Females achieved significantly better outcomes than males with the mean 46.5% of excess weight loss (EWL) versus 35.3% of EWL at 12 months ( p = 0.02). The mean percentage of excess weight loss (%EWL) was 43.6% at 12 months and 46.6% at 24 months. Major surgical complication rate was 7.1%; minor surgical complication rate 8.3%. There was one conversion (1.2%) due to the massive bleeding. Comorbidities improved or resolved in numerous patients: arterial hypertension in 62%, diabetes mellitus in 68.3%, respectively.


          Presented LSG series shows that the LSG as a stand-alone procedure provides acceptable %EWL and good global BAROS outcomes. It significantly improves comorbidities as well.

          Early experience with two-stage laparoscopic Roux-en-Y gastric bypass as an alternative in the super-super obese patient.

          Surgical management of the supersuper obese patient (BMI >60 kg/m2) has been a challenging problem associated with higher morbidity, mortality, and long-term weight loss failure. Current limited experience exists with a two-stage biliopancreatic diversion and duodenal switch in the supersuper obese patient, and we now present our early experience with a two-stage gastric bypass for these patients. We completed a retrospective bariatric database and chart review of super-super obese patients who underwent laparoscopic sleeve gastrectomy as a first-stage procedure followed by laparoscopic Roux-en-Y gastric bypass as a second-stage for more definitive treatment of obesity. During a two-year period, 7 patients with BMI 58-71 kg/m2 underwent a two-stage laparoscopic Roux-en-Y gastric bypass by two surgeons at the Mount Sinai Medical Center. 3 patients were female, 4 patients were male, and the average age was 43. Prior to the sleeve gastrectomy, the mean weight was 181 kg with a BMI of 63. Average time between procedures was 11 months. Prior to the second-stage procedure, the mean weight was 145 kg with a BMI of 50 and average excess weight loss of 37 kg (33% EWL). Six patients have had follow-up after the second-stage procedure with an average of 2.5 months. At follow-up the mean weight was 126 kg with a BMI of 44 and average excess weight loss of 51 kg (46% EWL). The mean operative times for the two procedures were 124 and 158 minutes respectively. The average length of stay for all procedures was 2.7 days. 4 patients had 5 complications, which included splenic injury, proximal anastomotic stricture, left arm nerve praxia, trocar site hernia, and urinary tract infection. There were no mortalities in the series. Laparoscopic sleeve gastrectomy with second-stage Roux-en-Y gastric bypass are feasible and effective procedures based on short-term results. This two-stage approach is a reasonable alternative for surgical treatment of the high-risk supersuper obese patient.

            Biliopancreatic diversion with a duodenal switch.

            This paper evaluates biliopancreatic diversion combined with the duodenal switch, forming a hybrid procedure which is a combination of restriction and malabsorption. The evaluation is of the first 440 patients undergoing this procedure who had had no previous bariatric surgery. The mean starting weight was 183 kg, with 41% of our patients considered super morbidly obese (BMI > 50). There was an average maximum weight loss of 80% excess weight by 24 months postoperation; this continued at a 70% level for 8 years. Major complications were found in almost 9% of the cases. There were two perioperative deaths, one from pulmonary embolism and one from acute pulmonary obstruction. There were 36 type II diabetics, all of whom have discontinued medication following the surgery. Seventeen revisions were performed to correct excess weight loss and low protein levels. There have been no marginal ulcers, no cases of dumping syndrome, no foreign material used, and the procedure is a pyloric saving procedure which is functionally reversible. This operation has vastly improved the lives of seriously obese patients with many comorbidities. All type II diabetics have essentially been cured of their disease. The procedure was tolerated well and patients are quite satisfied. There was minimal regain of weight with this method.

              Bariatric analysis and reporting outcome system (BAROS)

              The lack of standards for comparison of results was identified by the NIH Consensus Conference panelists as one of the key problems in evaluating reports in the surgical treatment of severe obesity. The analysis of outcomes after bariatric surgery should include weight loss, improvement in comorbidities related to obesity, and quality-of-life (QOL) assessment. Definitions of success and failure should be established and the presentation of results standardized. A survey among experienced bariatric surgeons was conducted to study the reporting of results. The concept of evaluating outcomes by using a scoring system was introduced in 1997 and has now been refined further. Psychologists with expertise in bariatrics were asked to recommend a disease-specific instrument to analyze QOL after surgery. The system defines five outcome groups (failure, fair, good, very good, and excellent), based on a scoring table that adds or subtracts points while evaluating three main areas: percentage of excess weight loss, changes in medical conditions, and QOL. To assess changes in QOL after treatment, this method incorporates a specifically designed patient questionnaire that addresses self-esteem and four daily activities. Complications and reoperative surgery deduct points, thus avoiding the controversy of considering reoperations as failures. The Bariatric Analysis and Reporting Outcome System (BAROS) analyzes outcomes in a simple, objective, unbiased, and evidence-based fashion. It can be adapted to evaluate other forms of medical intervention for the control of obesity. This method should be considered by international organizations for the adoption of standards for the outcome assessment of bariatric treatments, and for the comparison of results among surgical series. These standards could also be used to compare the long-term effects of surgery with nonoperative weight loss methods.
