Laparoscopic reoperation after LAGB is safe and feasible. Reoperation leads to further decrease of BMI and obesity-related comorbidities. Band replacement is a good option for patients with good weight loss after initial LAGB. Alternative procedures, preferably RYGBP, are required for cases of band failure. Overall, RYGBP appears to be the most effective option to induce further weight loss.
Background: The success rate of laparoscopic adjustable gastric banding (LAGB)in the treatment of morbid obesity isvery variable. A reasonable preoperative selection of eligible patients seems to be important for a successful outcome of LAGB. In the present study, criteria were investigated to predict the outcome of LAGB. Methods: 85 morbidly obese patients were operated with LAGB between 1999 and 2005. 71of these patients were analysed according to several possible predictive parameters of success or failure of LAGB. Success was defined as excess bodyweight loss (EBWL) > 50% without band removal, failure was defined as EBWL < 20% and/or band removal. Median follow-up was 27 months (range 8–90 months). Results: After LAGB a median EBWL of 43%(–41 to171.5%) was observed in all patients with a decrease in BMI of 8.0 kg/m2 (– 9 to 35 kg/m2). The success rate after LAGB was 37%, the failure rate 19.7%. Female sex (p = 0.023), baseline weight (p = 0.024), and eating behaviour after LAGB (p = 0.008) were significant predictors of success following LAGB, whereas complications such as port dislocation and reoperation after LAGB did not have a significant impact on a successful course following LAGB. Significant predictors of failure were male sex (p = 0.038) and missing physical activity after LAGB (p = 0.045), where as the eating behaviour did not have a significant effect concerning failure following LAGB. Baseline excess body weight (EBW) was identified as an independent predictor of failure in a multivariate analysis. Conclusion: According to the results of this study, female patients with a lower EBW who improve their postoperative eating behaviour have the best chanceof success following LAGB.
In times of manifold digital learning resources open to public access lectures in surgery still play a major role in medical training. It is a platform for discussion with the medical teacher and provides the opportunity to create a vivid learning experience by showing live operations via video streaming and inviting patients to the lectures. When then change in paradigm is achieved from pure knowledge transfer to cross-linkage of knowledge, the surgical lecture will be a major future keystone in medical education, where the lecturer can reach the students with his own passion for the field of expertise and get them interested in surgery.
Recent reports on the feasibility and safety of single-incision cholecystectomy have challenged the conventional multiport access to the gallbladder. Nevertheless, the proximity of different instruments and the laparoscope may lead to interference that potentially compromises the safety of the operation. This article describes the use of a customary flexible restraint system for the gallbladder fundus to achieve triangulation by means of a three-instrument technique and an optimized view to the Calot's triangle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
