Laparoscopic Surgery in 3D Improves Results and Surgeon Convenience in Sleeve Gastrectomy for Morbid Obesity

Abstract Background. Advanced laparoscopic procedures are still challenging. One critical issue is the lack of stereoscopic vision. The aim of this surgical study is to evaluate whether 3D vision offers any advantages for surgical performance over 2D vision during sleeve gastrectomy for morbid obesity using a laparoscopic system that allows changing between 2D and 3D optics.Method. A total of 78 patients were analyzed, with 37 in the 2D group and 41 in the 3D group. Performance time, hospital stay, complications and early outcomes were collected. To assess the quality of the 2D and 3D techniques, visual analog scales (VASs) from 0 to 10 were designed, and image quality, depth of field, precision in performing tasks and general ergonomics were measured.Results. According to the vision system used, the mean duration of surgery was 85 ± 16.8 minutes for patients operated on with the 2D system and 69 ± 16.9 minutes for those operated on with the 3D system. There were no significant differences between the overall percentages of complications according to the type of vision used. However, postoperative complications were more severe in the 2D laparoscopy group. The average length of stay was shorter for patients in the 3D group. Regarding the differences perceived by the surgeon, the depth of field and the precision of tasks were better in the 3D vision group.Conclusion. The 3D system provided greater depth perception and precision in more complex tasks, enabling safer surgery. This led to a reduction in the operative time and hospital stay. Moreover, the severity of complications was less.

Introduction. Laparoscopic sleeve gastrectomy (LSG) represents a valid option for morbid obesity, either as a primary or as a staged procedure. The aim of this paper is to report the experience of a single surgeon with LSG as a standalone operation for morbid obesity.Methods. From April 2006 to April 2011, 200 patients underwent LSG for morbid obesity. Each patient record was registered and prospectively collected. In July 2011, a retrospective analysis was conducted.Results. Patients were 128 females and 72 males with a median age of 40.0 years. Median pre-operative BMI was 49.4 kg/m2. Median follow-up was 27.2 months. Median post-operative BMI was 30.4 kg/m2. Median %excess weight loss (%EWL) was 63.6%. Median post-operative hospital stay was 4.0 days in the first 84 cases and 3.0 days in the last 116 cases. Six major post-operative complications occurred (3%): two gastric stump leaks (1%), three major bleedings (1.5%) and 1 (0.5%) bowel obstruction. One case of mortality was registered (0.5%). To date only 4 patients are still in the range of morbid obesity (BMI > 35 kg/m2).Conclusions. Laparoscopic sleeve gastrectomy is a formidable operation in the short-term period. Median %EWL in this series was 63.6% at 27.2 months follow-up.

Aim: The aim of this study is to investigate the efficacy of thiol disulfide homeostasis and Ischemia Modified Albumin (IMA) values in predicting the technical difficulties that might be encountered during laparoscopic cholecystectomy. Materials and Methods: The study included 65 patients who underwent laparoscopic cholecystectomy due to cholelithiasis at the General Surgery Clinic of Ankara Numune Training and Research Hospital. All patients’ demographic data, previous history of cholecystitis, a history of chronic illness, preoperative white blood count (WBC), liver function tests (AST, ALT), amylase and lipase levels, intra-operative adhesion score, the ultrasonographic appearance of gallbladder, duration on hospital stay, duration of operation, thiol disulfide and IMA values were evaluated. Results: Native thiol and total thiol averages were higher in patients without a history of cholecystitis, on the other hand, disulfide, disulfide/native thiol rate, disulfide/total thiol rate, native thiol/total thiol rate and IMA averages were higher in patients with a history of cholecystitis. While there was a statistically significant negative correlation between native and total thiol values and age, duration of surgery and duration of hospital stay; IMA, disulfide, disulfide/Total thiol, Native/Total thiol and disulfide/Native thiol rates were higher in older patients with a longer duration of surgery and hospital stay. In addition, preoperative IMA, disulfide, disulfide/Total thiol, Native/Total thiol and disulfide/Native thiol were observed to increase as the degree of intraoperative pericholecystic adhesion increased. Conclusion: We believe that the evaluation of thiol disulfide homeostasis and IMA parameters prior to laparoscopic cholecystectomy can be used as an effective method for predicting intraoperative difficulties.

Abstract Background Bariatric surgery is effective for the treatment of patients with morbid obesity and type 2 diabetes mellitus (T2DM), for body weight loss and glycemic control. However, in Japan, there has been no previous report of the effectiveness bariatric surgery in a case of morbid obesity associated with acute onset type 1 diabetes mellitus (T1DM), in which pancreatic β-cells were destroyed and endogenous insulin was depleted. Case presentation A 36-year-old woman with morbid obesity and T1DM, diagnosed when she was 6 years, was admitted for bariatric surgery. At her first consultation, she had a body weight of 106.7 kg and a body mass index of 42.2 kg/m2. Her HbA1c level was 9.0%, with a required daily insulin dose of 75 units. She underwent laparoscopic sleeve gastrectomy. At 1 year after surgery, her body weight had decreased to 81.0 kg and her body mass index to 32.2 kg/m2. In addition, her daily required dose of insulin had decreased to 24 units, with an improvement in her HbA1c level to 7.7%. Conclusions Although further evidence needs to be accumulated, including long-term outcomes, laparoscopic sleeve gastrectomy may provide an effective treatment for patients with morbid obesity and T1DM for body weight loss, improvement in HbA1c level, and insulin dose reduction.
