Laparoscopic Sleeve Gastrectomy Smart Trocar Site Modification in Patients with Extreme Obesity.

PURPOSE: Laparoscopic sleeve gastrectomy (LSG) is one of the most common bariatric surgeries performed worldwide. Although it has established itself as a satisfactory procedure on its own, it can also function as the first part of a two-stage treatment strategy. This is especially true in situations of extreme obesity (obesity grade IV or higher). One rationale for choosing a two-stage treatment is the technical difficulty of doing other types of bariatric procedures involving anastomoses due to body physique and level of visceral adiposity. LSG in patients with such a high body mass index (BMI) is comparatively simpler technically, but it does also have a degree of complexity for similar reasons. Here, we present an innovative port configuration for LSG that can significantly reduce ergonomic challenges and enhance the safety of the procedure in patients with extreme obesity. MATERIALS AND METHODS: This new trocar site arrangement is generally suitable for individuals with grade IV obesity or above. It is especially effective for people with obesity at or above grade V. Only standard laparoscopic instruments are used. RESULTS: This design preserves the ideal manipulation and elevation angles at 60° and allows surgeons to use standard laparoscopic instruments with lowered shoulders, reducing muscular strain and fatigue. Additionally, it improves patient safety. CONCLUSION: In patients with extreme obesity, this proposed port configuration for LSG can significantly reduce ergonomic difficulties and increase surgical safety.

Evaluation of the Incidence of Low Testosterone Levels in Young Male Adults with Moderate to Severe Obesity-Single-Centre Study from India.

PURPOSE: With the increase in obesity epidemic among Asians, it is necessary to evaluate the impact of obesity on this population. Low testosterone levels are known to be associated with obesity. This is the 1st study from Asia to evaluate incidence and magnitude of hypotestosteronemia in young adults with BMI more than 32.5 kg/m2 defined as moderate to severe obesity in Asians. MATERIALS AND METHODS: One hundred thirty-four male patients with BMI more than 32.5 kg/m2, between 18 and 30 years old who visited a single bariatric facility between 2017 and 2020, were evaluated with BMI, total and free testosterone levels and clinical features of gynecomastia, hypogonadism, and thinning of pubic and armpit hair. Statistical analysis was performed using SPSS, Spearman's correlation coefficient, and ANOVA test. RESULTS: 60.4% of patients (84/134) had low testosterone levels (< 300 ng/dl) and 23.9% (32/134) had levels between 300 and 400 ng/dl. 89.6% patients (120/134 had gynecomastia, 60.4% (81/134) had thinning of pubic and arm pit hair, and 62.7% (84/134) had hypogonadism. Testosterone levels showed a decreasing trend with increasing BMI, but it was not statistically significant. CONCLUSION: Obesity is one of the important etiologies of hypotestosteronemia and its manifestations in young adults. The actual incidence may be significantly higher than what is reported in the literature. High-quality research is required to address questions of diagnosis and best treatment options.

Adipocytokines and anthropometric measures in type 2 diabetics.

AIM: Type 2 diabetes mellitus has assumed pandemic proportions worldwide. Aggressive management of hyperglycemia in diabetics is a primary goal of treatment. We have previously reported favorable effects of oral hypoglycemic agents on adipocytokines. Aim of the present study was to investigate the relationship of adipocytokines with anthropometric measures and biochemical parameters in type 2 diabetics. METHODS: Clinically diagnosed type 2 diabetics and age, gender matched healthy volunteers were recruited for study. Anthropometric measurements like height, weight, waist-circumference, hip-circumference were recorded and BMI, waist-hip ratio were calculated. Fasting blood samples were collected from participants and sera were analyzed for glucose, glycated haemoglobin, total cholesterol, SGOT, SGPT, insulin, adiponectin and leptin. Correlation of adipocytokines with anthropometric and biochemical parameters was assessed in healthy and diabetic individuals. RESULTS: BMI and WHR in diabetics were significantly higher than healthy population. BMI did not show significant association with adipocytokines. Diabetic males with WHR≥0.9 showed negative association with adiponectin and positive association with leptin. WC did not show significant association with adipocytokines in males. Irrespective of WC, healthy females exhibited positive association with leptin. Diabetic females with WC≥88cm showed leptin to be positively associated with WC. Such association of adipocytokines with WHR was not detected in females. CONCLUSIONS: Body fat distribution can be considered as a parameter in assessing adipokine imbalance. Central adiposity is a better measure of adipokine imbalance than BMI. Abdominal obesity in diabetics correlates with altered levels of adipocytokines indicating its importance in diabetic individuals.

Buttressing the staple line: a randomized comparison between staple-line reinforcement versus no reinforcement during sleeve gastrectomy.

Bariatric surgery is recommended for Indian patients with body mass index (BMI) >32.5 kg/m(2) with at least one comorbidity and >37.5 kg/m(2) without a comorbidity. In laparoscopic sleeve gastrectomy, bleeding and leakage from the staple line are common post-operative events. Peri-Strips Dry® with Veritas® (PSD-V) is used in staple-line reinforcement. This was a single-investigator, multicenter, randomized study of 100 patients undergoing standard sleeve gastrectomy with a 34 or 36 French bougie. Patients were randomized 1:1 to PSD-V or control groups; no buttress material was used in the control group. The primary objective was to assess complication rates (any staple-line bleed or leak from the intra-operative visit through day 30) associated with sleeve gastrectomy. Surgical time (from first incision to closure of last incision) and the number of clips and/or sutures used to control bleeding were also assessed. Fewer staple-line bleeds were observed in the PSD-V group than the control group (23/51 [45.1 %] vs 39/49 [79.6 %] patients; p=0.0005), and the bleeding was of a lower severity (p=0.0002). No staple-line leaks were observed. Surgical time was shorter in patients who received PSD-V (58.8 vs 72.8 min; p=0.0153), and fewer patients required hemostatic clips and/or sutures (10/51 [19.6 %] vs 33/49 [67.3 %] patients; p<0.0001). Fewer patients in the PSD-V than the control group experienced adverse events (2/51 [3.9 %] vs 5/49 [10.2 %] patients). The use of PSD-V reduced the incidence and severity of staple-line bleeding and was associated with a reduction in surgical time compared with no staple-line reinforcement.

Effectiveness of laparoscopic sleeve gastrectomy on glycemic control in obese Indians with type 2 diabetes mellitus.

BACKGROUND: To prospectively evaluate the efficacy and safety of laparoscopic sleeve gastrectomy (LSG) in Indian subjects with type 2 diabetes mellitus and a body mass index >33 kg/m(2) in a tertiary care hospital in Pune, India. Morbid obesity associated with type 2 diabetes mellitus has many health implications. A definitive long-term strategy is needed to control obesity and its deleterious effects. LSG is one such approach. METHODS: The patients who underwent LSG were followed up until the end of 1 year after surgery. The change in hemoglobin A1c levels, waist circumference, total body weight, and the use of oral hypoglycemic agents and insulin were studied. RESULTS: A total of 53 patients (24 men and 29 women, age 46.5 +/- 8.7 years, body mass index 45.2 +/- 9.3 kg/m(2), waist circumference 117 +/- 18 cm, and hemoglobin A1c 8.4% +/- 1.6%) fulfilled the entry criteria and underwent LSG. Before LSG, 48 patients (79%) required antidiabetic medication (oral hypoglycemic agents and insulin) and 5 managed their diabetes with diet control. At 1 month after LSG, 39 (81.2%) of 48 patients no longer required antidiabetic medications and had achieved euglycemia with diet control alone. The use of antidiabetic medications was reduced in 9 (18.8%) of 52 patients. At 1 year, euglycemia was observed in 51 patients (96.2%) without medication and 2 (3.8%) of the 53 patients had reduced their medication dosage. CONCLUSION: LSG is an effective adjunct in the treatment of type 2 diabetes mellitus in obese individuals. It appears that improvement in glycemic control is achieved even before weight reduction, and the possible mechanisms explaining this need further investigation.

Diabetes remission and reduced cardiovascular risk after gastric bypass in Asian Indians with body mass index <35 kg/m(2).

BACKGROUND: Roux-en-Y gastric bypass (RYGB) benefits patients with type 2 diabetes mellitus (T2DM) and a body mass index (BMI) >35 kg/m(2); however, its effectiveness in patients with T2DM and a BMI <35 kg/m(2) is unclear. Asian Indians have a high risk of T2DM and cardiovascular disease at relatively low BMI levels. We examined the safety and efficacy of RYGB in Asian Indian patients with T2DM and a BMI of 22-35 kg/m(2) in a tertiary care medical center. METHODS: A total of 15 consecutive patients with T2DM and a BMI of 22-35 kg/m(2) underwent RYGB. The data were prospectively collected before surgery and at 1, 3, 6, and 9 months postoperatively. RESULTS: Of the 15 patients, 8 were men and 7 were women (age 45.6 +/- 12 years). Their preoperative characteristics were BMI 28.9 +/- 4.0 kg/m(2), body weight 78.7 +/- 12.5 kg, waist circumference 100.2 +/- 6.8 cm, and duration of T2DM 8.7 +/- 5.3 years. At baseline, 80% of subjects required insulin, and 20% controlled their T2DM with oral hypoglycemic medication. The BMI decreased postoperatively by 20%, from 28.9 +/- 4.0 kg/m(2) to 23.0 +/- 3.6 kg/m(2) (P <.001). All antidiabetic medications were discontinued by 1 month after surgery in 80% of the subjects. At 3 months and thereafter, 100% were euglycemic and no longer required diabetes medication. The fasting blood glucose level decreased from 233 +/- 87 mg/dL to 89 +/- 12 mg/dL (P <.001), and the hemoglobin A1c decreased from 10.1% +/- 2.0% to 6.1% +/- 0.6% (P <.001). Their waist circumference, presence of dyslipidemia, and hypertension improved significantly. The predicted 10-year cardiovascular disease risk (calculated using the United Kingdom Prospective Diabetes Study equations) decreased substantially for fatal and nonfatal coronary heart disease and stroke. No mortality, major surgical morbidity, or excessive weight loss occurred. CONCLUSION: RYGB safely and effectively eliminated T2DM in Asian Indians with a BMI <35 kg/m(2). Larger, longer term studies are needed to confirm this benefit.

Long-term effects of laparoscopic sleeve gastrectomy in morbidly obese subjects with type 2 diabetes mellitus.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is becoming popular as a stand-alone procedure for the treatment of morbid obesity and related diseases. This retrospective study presents the outcomes of LSG with regard to weight loss and improvement in co-morbidities and quality of life (QOL) at the end of 3 years after surgery in a tertiary care hospital in Pune, India. METHODS: A total of 23 patients with type 2 diabetes mellitus (6 men and 17 women) with morbid obesity (mean body mass index 40.7 +/- 6.6 kg/m(2)) who had undergone LSG from 2004 to 2005 were selected for the present analysis. The percentage of excess weight loss and changes in co-morbidity status and QOL at the end of 3 years were calculated. The patients were simultaneously evaluated using the Bariatric Analysis and Reporting Outcome System scores. P values <.05 were considered significant. RESULTS: At 36 months after surgery, the percentage of excess weight loss was 74.58%, a significant number of patients (16 of 23, P <.05) had had improvement in all co-morbidities, and 7 showed improvement in >or=1 co-morbidity. All patients indicated improvement in their QOL but not equally for all parameters included in the questionnaire. The Bariatric Analysis and Reporting Outcome System score was good in 4, very good in 4, and excellent in 15 of the 23 patients. CONCLUSION: Our data have shown that LSG is a highly effective and safe procedure for achieving weight loss, improving co-morbidities, and improving the QOL in patients with type 2 diabetes mellitus and morbid obesity during a long-term period.
