Effect of laparoscopic mini-gastric bypass versus laparoscopic sleeve gastrectomy on hypertension and dyslipidemia in obese type 2 diabetes mellitus patients.

Objective: The aim of the research was to compare the effect of the laparoscopic mini-gastric bypass (LMGB) technique with the laparoscopic sleeve gastrectomy (LSG) technique in bariatric surgery on type 2 diabetes mellitus (T2DM), hypertension (HTN), and dyslipidemia in obese T2DM patients. Materials and methods: A prospective, cross-sectional study, conducted in Surgery Department at Al-Mouwasat and Al-Assad University Hospitals in Damascus, and included T2DM obese patients who would undergo bariatric surgery using the LMGB or LSG technique. Results: The research included two groups: the LSG group (92 patients, 60.9% female, age 44.6 year, BMI 41.85 kg/m2) and the LMGB group (137 patients, 59.1% female, age 47.1 year, BMI 43 kg/m2). Before surgery, the prevalence of HTN and dyslipidemia were similar in the two groups. After one year: T2DM improvement and remission rate in the LMGB group (13.9, 80.3%) were greater than in the LSG group (13, 62%), the difference was statistically significant. The HTN improvement and remission rate in the LMGB group (52.9, 41.4%) were greater than in the LSG group (47.5, 39%), the difference was not statistically significant. The dyslipidemia improvement rate was greater in LSG group (47.2 vs. 32.7%), while the dyslipidemia remission rate was greater in LMGB group (67.3 vs. 52.8%), the difference was statistically significant. Conclusions: The authors found that the LMGB technique was more effective than the LSG technique in controlling cardiovascular risk factors of obesity, T2DM, HTN, and dyslipidemia.

Sleeve gastrectomy versus mini-gastric bypass and their effects on type II diabetes mellitus and weight loss outcome.

Bariatric surgeries such as sleeve gastrectomy; mini-gastric bypass surgery are successful weight reduction surgeries which significantly impact metabolic syndrome. The purpose of this research was to assess the impact of laparoscopy gastrectomy and mini-gastric bypasses on weight decrease and diabetes remission of diabetic mellitus type 2 through two years of monitoring. Furthermore, this study looked at the difference between the two procedures regarding their efficacy and identify which one is proper for patients according to their comorbidities. A prospective study was held in Al Sadder Medical City and Al-Gadeer private hospitals in Al-Najaf city, Iraq, from January 2016 to February 2018. The study included 35 obese and morbidly obese patients with a known history of diabetes mellitus type 2, diagnosed from at least two years before surgery. 15 patients undergo uneventful laparoscopic sleeve gastrectomy (6 females and 9 males). 20 patients underwent uneventful laparoscopic gastric mini bypass surgery (6 females and 14 males). In addition, the patients were followed in the short-term postoperatively (3, 6, 12, 24 months) by monitoring their BMI, weight loss, and HbA1c. There was a decrease in BMI of about 45% from the baseline BMI in sleeve gastrectomy surgery and a decrease in HbA1c of about 45%, less than 6%. In gastric mini-bypass surgery, there was a decrease in BMI of about 47% from the baseline BMI and a decrease in HbA1c of about 45% from the baseline less than 6%, during a 24-month monitoring. Both surgeries were fruitful and had efficient results on patients, but the gastric mini bypass was more efficient than sleeve gastrectomy in controlling and remission of DM type 2 without the need for medications. A long-term study should be performed to reveal their effect and benefits to the patients.

Predicting remission of diabetes post metabolic surgery: a comparison of ABCD, diarem, and DRS scores.

BACKGROUND: Obesity is one of the major causes for development of T2DM. Metabolic surgery has been proved to be a successful and cost-effective treatment modality for managing the patients with obesity and T2DM. Many scoring systems and models have been described in literature to predict the outcome of T2DM after metabolic surgery. The aim of this study is to compare the efficacy of Diarem, DRS, and ABCD score in predicting the T2DM remission. METHODS: A total number of 102 diabetic patients, who underwent LMGB/LOAGB, were selected for this study. A retrospective analysis of the three scoring systems when applied to these patients and their predictive abilities were analyzed. RESULTS: At 1 year after surgery, 72 (70.59%) patients achieved remission of T2DM. Though the pairwise comparisons between AUC on ROC analysis of ABCD, Diarem, and DRS scores does not show statistically significant difference between them, Diarem score has the maximum relative area under ROC curves. By multivariate analysis, it was found that factors significantly associated with T2DM remission were duration of T2DM, C-peptide, and Pre-Op HbA1c. CONCLUSIONS: Among the three scoring systems, though DiaRem score has the best sensitivity and specificity and maximum AUC, no statistically significant difference was found in their diabetes remission predicting abilities. A shorter duration of T2DM, a lower HbA1C, and higher levels of C-peptide were significantly associated with a higher chance of T2DM remission.

Seven Years of Mini-Gastric Bypass in Type II Diabetes Patients with a Body Mass Index <35 kg/m(2).

BACKGROUND: Mini-gastric bypass (MGB) is a safe, effective, and reversible procedure for patients with type II diabetes mellitus (T2DM) and morbid obesity. Less is known, however, about its long-term effects in patients with a body mass index (BMI) <35 kg/m(2). METHODS: From February 2007 to February 2014, 1468 patients underwent MGB at our institution, including 983 with T2DM. Of these, 128 (82 women), of mean age 41.6 ± 10.2 years, had a BMI of 30-35 kg/m(2). Prospectively collected data were analyzed retrospectively. Factors assessed included disease duration, family history, medication use, remission, and biochemical indicators, including fasting plasma glucose, glycosylated hemoglobin (HbA1c), serum insulin, and C-peptide concentrations. Remission of T2DM was defined as HbA1c <6.0 % without medication. RESULTS: Prior to surgery, patients had a mean BMI of 33.4 ± 3.3 kg/m(2), mean waist circumference of 104.5 ± 8.2 cm, mean C-peptide concentration of 3.4 ± 1.2 ng/ml, and mean T2DM duration of 6.5 ± 3.1 years. Within 6 months of MGB, 95 % of these patients had attained HbA1c <7 %. Complete remission rates at 1, 2, and 7 years were 64, 66, and 53 %, respectively. Mean HbA1c decreased from 10.7 ± 1.5 % at baseline to 6.2 ± 0.5% at 1 year, 5.4 ± 1.2 % at 3 years, and 5.7 ± 1.8 % at 7 years. No deaths occurred, but two (1.6 %) patients experienced major complications. CONCLUSIONS: MGB provides good, long-term control of T2DM in patients with class I obesity. Early intervention results in higher remission rates.

Revision of failed primary adjustable gastric banding to mini-gastric bypass: results in 48 consecutive patients.

Although laparoscopic adjustable gastric banding (LAGB) has been found to be a generally successful weight loss operation, many patients require revision for weight regain, mechanical complications or intolerance to restriction. We report our experience with laparoscopic mini-gastric bypass (LMGB) as a revisional procedure for failed primary LAGB. From June 2007 to November 2012, 48 patients, who had undergone LAGB, underwent revisional surgery to LMGB. Patient demographics, reasons for band removal, interval between removal and LMGB, operative times, complications, change in comorbidities, and weight loss were collected. The revisions to a mini-gastric bypass (MGB) were completed laparoscopically in all cases except in four, when the MGB was deferred because of gastric tube damage. Mean age was 38 years (range 20-59) and BMI was 43.4 ± 4.2 kg/m(2); 82 % of patients were females. Revision was performed after a mean of 28.6 months. The mean hospital stay was 3.25 days. Within 60 days of the MGB, mortality and morbidity were nil. We observed a significant difference in mean BMI after 6 months' follow-up (P < 0.001). Diabetes remission was observed in 88 % of patients, apnea remission in 66 %, and hypertension remission in 66 % after LMGB (p < 0.001). Moreover, four patients with GERD were cured. All LAGB patients had positive outcomes after the conversion to MGB, with a mean gain of 1.7 points in the bariatric analysis and reporting outcome system questionnaire. Our results suggested that LMGB is a safe, feasible, effective and easy-to-perform revisional procedure for failed LAGB.

Efficacy and safety of laparoscopic mini gastric bypass. A systematic review.

BACKGROUND: Laparoscopic mini-gastric bypass (LMGB) is a relatively new bariatric procedure; published studies are accumulating in various settings. The objective of this study was to summarize the available evidence about the efficacy and safety of LMGB. METHODS: A systematic search in the literature was performed , and PubMed and reference lists were scrutinized (end-of-search date: July 15, 2013). For the assessment of the eligible articles, the Newcastle-Ottawa quality assessment scale was used. RESULTS: Ten eligible studies were included in this study, reporting data on 4,899 patients. According to all included studies, LMGB induced substantial weight and body mass index reduction, as well as substantial excess weight loss. Moreover, resolution or improvement in all major associated medical illnesses and improvement in overall Gastrointestinal Quality of Life Index score were recorded. Major bleeding and anastomotic ulcer were the most commonly reported complications. Readmission rate ranged from 0%- 11%, whereas the rate of revision operations ranged from .3%- 6%. The latter were conducted due to a variety of medical reasons such as inadequate or excessive weight loss, malnutrition, and upper gastrointestinal bleeding. Finally, the mortality rate ranged between 0% and .5% among primary LMGB procedures. CONCLUSION: LMGB represents an effective bariatric procedure; its safety and minimal postoperative morbidity seem remarkable. Randomized comparative studies seem mandatory for the further evaluation of LMGB.

A decade of bariatric surgery. What have we learned? Outcome in 520 patients from a single institution.

BACKGROUND: Today a variety of bariatric surgical procedures is available and, currently, it is difficult to identify the most effective option based on patient characteristics and comorbidities. Aim of this retrospective study is to evaluate the efficacy of four different techniques; Intragastric Balloon (IB), Laparoscopic Adjustable Gastric Banding (LAGB), Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Mini Gastric Bypass (LMGB), performed in our unit along ten years. PATIENTS AND METHODS: Starting from January 2005, 520 patients, 206 men (39.6%) and 314 women (60.4%) were treated at our institution. Among patients candidate to bariatric surgery 145 underwent IB, 120 underwent LAGB, 175 underwent LSG and 80 underwent LMGB. Follow up rate was 93.1% for IB at 6 months; 74.1% and 48% for LAGB at 36 and 60 months respectively; 72.8% and 58.1% for LSG at 36 and 60 months respectively; and 84.2% for LMGB at 36 months. RESULTS: The period 2005-2014 has been considered. Mortality was 1/520 patients (0.19%). The excess weight loss rate (EWL%) has been 32.8 for IB at six months, 53.7 for LAGB and 68.1 for LSG, at 60 months respectively and 79.5 for LMGB at 36 months. Early major postoperative complications requiring surgery were 0.6% for IB and 1.1% for LSG whereas late major postoperative complications were 1.2% for IB, 4.1% for LAGB and 0.5% for LSG. Diabetes resolution rate was 0 for LAGB, 76.9% for LSG and 80% for LMGB at 36 months. CONCLUSIONS: If more invasive procedures as LSG or LMGB may entail higher operative and peroperative risks, conversely, in skilled hands their efficacy remains undisputed, especially in the long term, presenting a very low rate of major complications. In general, the efficacy of a bariatric surgery unit seems improved by the capability to offer both different primary procedures and re-do surgery.
