Excess Weight Loss (excess + weight_loss)
Selected AbstractsBT04 LAPAROSCOPIC REVISION OF GASTRIC BAND SURGERYANZ JOURNAL OF SURGERY, Issue 2009S. Bardsley Aim: , To identify the outcome of laparoscopic revision of gastric band surgery with respect to percentage of excess weight lost (%EWL). Methods: , Analysis of a prospective database was performed and %EWL was plotted with respect to time from initial procedure and also time from revision procedure. Results: , All revision operations were performed laparoscopically. There were no patient deaths, but two serious complications. Percentage Excess Weight Loss after replacement of the band because of prosthetic failure or dysphagia was 57% at an average follow up of 19 months. For repositioning of the band due to slippage, the %EWL was 72% at an average of 15 months follow up for those who had the existing band repositioned, and 42% at an average of 23 months follow up for those who had a new band repositioned. Conclusion: , Revision laparoscopic gastric band surgery is a safe option for patients, and results in good %EWL at an average follow up period of 19 months. [source] Perspective on biomaterials used in the surgical treatment of morbid obesityOBESITY REVIEWS, Issue 3 2009J. A. Henry Summary Morbid obesity is defined as having a body mass index greater than or equal to 40.0 kg m,2, or 37.0 kg m,2 with comorbidities. Bariatric surgery remains the most effective treatment for morbid obesity. Bariatric procedures such as sleeve gastrectomy, vertical banded gastroplasty and adjustable gastric banding all generate excess body-weight loss typically over 3,5 years. The biomaterials used during these procedures, namely silicone, polypropylene, expanded polytetrafluoroethylene and titanium, are all non-degradable biomaterials. Hence, their presence in vivo exceeds the functional requirement of an implant to treat morbid obesity. Accordingly, research into non-invasive and reversible surgical procedures has increased, particularly in light of the dramatic increase in paediatric obesity. Tissue engineering is an alternative approach to treat morbid obesity, as it incorporates both engineering and biological principles into the design and development of an implant to surgically treat morbid obesity. It is hypothesized that a biodegradable polymer to treat morbid obesity could be developed to effectively promote excess weight loss. The aim of this review is to discuss morbid obesity with regards to its aetiology, prevalence and current modalities of treatment. Specifically, the shortcomings of the biomaterials currently used to surgically treat morbid obesity shall be reviewed, and alternative biomaterials shall be proposed.

[source] Initial experience in laparoscopic sleeve gastrectomy for Japanese morbid obesityASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2009M Ohta Abstract Introduction: We evaluated the safety and efficacy of laparoscopic sleeve gastrectomy (LSG) in Japanese patients with morbid obesity. Materials and Methods: Between June 2006 and March 2009, seven morbidly obese Japanese patients (four women, three men; mean age 36±12 years; mean body mass index (BMI) 51±3 kg/m2) underwent LSG at our institute. The inclusion criteria were morbid obesity (BMI>35 kg/m2), the presence of obesity-related disorders, and failure to lose weight while using other medical therapies for at least 6 months. The criteria also included contraindications for laparoscopic adjustable gastric banding or super-obesity (BMI>50 kg/m2). LSG was carried out using endoscopic linear staplers from the greater curvature of the antrum 6,7 cm proximal to the pyloric ring to the angle of His alongside a 32-Fr endoscope or a 45-Fr overtube of the endoscope. Results: In all of the patients, LSG was successfully performed without open conversion. There were no serious postoperative complications and there was no mortality. The mean weight loss and percent excess weight loss after LSG were 33±8 kg and 47±16% at 6 months, and then 44±16 kg and 63±30% at 12 months. Due to the weight loss, the resolution and improvement rates of comorbidities in the five patients followed up for >3 months were 100% and 100% in type 2 diabetes, 67% and 100% in hypertension, 60% and 100% in dyslipidemia, and 100% and 100% in metabolic syndrome. Discussion: Although further long-term studies are necessary with regard to weight maintenance, LSG is a feasible and safe treatment for Japanese patients with morbid obesity. [source] Randomized clinical trial of laparoscopic Roux-en-Y gastric bypass versus laparoscopic vertical banded gastroplasty for obesity,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 5 2005T. Olbers Background: Laparoscopic techniques have been developed for performing Roux-en- gastric bypass (LRYGBP) and vertical banded gastroplasty (LVBG) in patients with morbid obesity. It is not certain, however, which is the better technique in non-superobese patients (body mass index less than 50 kg/m2). Methods: Eighty-three patients (LRYGBP 37, LVBG 46) were assessed in a randomized clinical trial. Perioperative complications were recorded together with preoperative and postoperative respiratory function and mobilization rate. Patients were monitored for 2 years after operation with regard to weight change and the need for remedial surgery. Results: There were no conversions to open surgery. The mean operating time was longer for LRYGBP than LVBG (138 versus 105 min). Five early reoperations were performed after LRYGBP (three for haemorrhage, one for ileus and one suspected leak) and one after LVBG (suspected leak). There were no differences in postoperative respiratory function or mobilization. Weight reduction was greater after LRYGBP (excess weight loss 78·3 versus 62·9 per cent 1 year after surgery, P = 0·009; 84·4 versus 59·8 per cent at 2 years, P < 0·001). Remedial surgical intervention was required in eight patients after LVBG (conversion to Roux-en- gastric bypass) and none after LRYGBP. Conclusion: LRYGBP and LVBG were comparable in terms of operative safety and postoperative recovery, but weight reduction was better after LRYGBP.
