    Laparoscopic obesity surgery in an Asian Institute: A 10-year prospective study with review of literature

    ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 2 2009
    Wei-Jei Lee
    Abstract Objective: Obesity surgery is the most effective treatment for morbid obesity and leads to dramatic improvement in related co-morbidities. The aim of this study was to present the long-term results of a prospective trial studying the efficacy of laparoscopic obesity surgery in a group of oriental patients. Method: From April 1998 to March 2009, 2385 patients who underwent obesity surgery in a single bariatric center in Asia were recruited. Various procedures have been adopted so far, including laparoscopic vertical banded gastric partition in 652 patients (27.3%), laparoscopic gastric bypass (LGB) in 1228 patients (51.5%), laparoscopic adjustable gastric banding in 226 patients (9.5%), laparoscopic sleeve gastrectomy in 128 patients (5.4%), gastric balloon in 68 patients (2.8%) and laparoscopic revision surgery in 83 patients (3.5%). We evaluated the clinical data and effect of obesity surgery on different procedures. Results: Overall, the major complication rate and mortality were 1.5% and 0.12%. There was an increase of surgical risk in laparoscopic sleeve gastrectomy and laparoscopic revision surgery patients. The mean total weight loss for the population was 28.1%, 33.9%, 21.3% 18.7% and 17.4% at 1, 3, 5, 7 and 9 years after surgery, respectively. LGB had a better weight loss (30.1%) than that of the restrictive-type procedures (20.9%) at 5 years after surgery. After surgery, most of the obesity-associated co-morbidities were resolved or improved in these patients. Conclusion: Laparoscopic obesity surgery resulted in significant and sustained weight loss in morbidly obese Asian patients with resolution of associated co-morbidities. LGB had a better result in weight reduction than other restrictive procedures. [source]

    Improvements in insulin sensitivity and ,-cell function (HOMA) with weight loss in the severely obese

    DIABETIC MEDICINE, Issue 2 2003
    J. B. Dixon
    Abstract Aims To examine the effect of weight loss on insulin sensitivity and ,-cell function in severely obese subjects of varying glycaemic control. Patients and methods Subjects were 254 (F:M 209:45) patients having adjustable gastric banding for severe obesity, with paired biochemical data from before operation and at 1-year follow up. The homeostatic model assessment method was used to calculate insulin sensitivity (HOMA%S) and ,-cell function (HOMA%B). Subjects were grouped by diabetic status and by pre-weight loss HbA1c. Results Initial mean (sd) weight and body mass index were 128 (26) kg and 46.2 (7.7) kg/m2, respectively, and at 1-year were 101 (22) kg and 36.4 (6.7) kg/m2. The percentage of excess weight lost (%EWL) was 44.3 (14)%. HOMA%S improved from 37.5 (16)% presurgery to 62 (25)% (P < 0.001). %EWL was the only predictor of HOMA%S improvement (r = 0.28, P < 0.001). Subjects with normal fasting glucose, impaired fasting glucose and Type 2 diabetes had a fall, no change and increase in HOMA%B, respectively. The improvement in HOMA%B in subjects with diabetes (n = 39) was inversely related to the time with diabetes (r = ,0.36, P = 0.02). In non-diabetic subjects the HOMA%S,HOMA%B relationship was favourably altered with weight loss, so that for any given HOMA%S there was an increase in HOMA%B (f = 11.8, P = 0.001). This improvement in HOMA%B was positively related to %EWL (r = 0.25, P = 0.019). Discussion There are beneficial changes in both insulin sensitivity and ,-cell function with weight loss. Modern laparoscopic obesity surgery may have an important early role in the management of Type 2 diabetes in obese subjects. [source]
