Portion Control Eating—a Determinant of Bariatric Outcomes

Introduction

Bariatric surgery leads to significant weight loss but the results vary. Application of dietary principles like portion-controlled eating leads to greater weight loss and fewer complications.

Aims

To evaluate the improvement in weight loss outcomes by incorporating portion-controlled eating behavior in postbariatric patients.

Methods

All patients who underwent bariatric surgery from January 2012 to December 2013 were included in the study. Portion-controlled eating behavior was incorporated in the post-bariatric nutritional protocol. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically.

Results

Three hundred and seventy-two (89.6%) underwent laparoscopic sleeve gastrectomy (LSG), while 43 (10.4%) underwent laparoscopic Roux-en-Y gastric bypass (RYGB). In the LSG group, lowest (nadir) BMI was 28.99?±?5.6 kg/m² and % Excess weight loss (EWL) was 87.3?±?27.2%, achieved between 1 and 2 years. In the RYGB group, lowest (nadir) BMI was 27.5?±?12.09 kg/m and % EWL was 94.32?±?33.12%. Surgical failure (less than 50% EWL) were 10 (3.27%) in the LSG group and 1 (3%) in the RYGB group. There were no leaks reported in our study.

Conclusion

Our study highlights the importance of postoperative nutritional interventions like portion-controlled eating for successful bariatric outcome.

     

The Effects of Laparoscopic Sleeve Gastrectomy on Obesity-Related Hypertriglyceridemia-Induced Acute Pancreatitis

Background

Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is a significant clinical problem and is characterized by high recurrence rate compared with non-HTG-AP. The objective of this study was to investigate the effects of laparoscopic sleeve gastrectomy (LSG) on obesity-related HTG-AP.

Methods

Twenty-nine patients with obesity-related HTG-AP were admitted to our hospital and treated with the conventional therapy or LSG surgery according to the wishes of patients. Clinical data and the recurrence rate of AP were collected at baseline and at four different time points (3, 6, 9, and 12 months) after the treatments for all patients.

Results

Of the 29 patients, 28 patients (19 patients with conventional therapy and 9 patients with LSG surgery) completed the 12-month follow-up. Clinical data and the severity scores of AP were comparable at baseline when the patients were admitted to the intensive care unit. The LSG group experienced a large weight loss (percent total weight loss, 26.87?±?1.44%; percent excess weight loss, 79.56?±?1.37%) and triglyceride reduction (from 15.77?±?1.02 to 1.36?±?0.09 mmol/L), and no recurrence was observed at 12 months after the surgery. In the conventional treatment group, however, body weight was not changed although triglyceride was significantly decreased (from 17.34?±?1.29 to 8.25?±?1.12 mmol/L), and more importantly, 47.4% of the patients had at least one recurrence of AP in 12 months after the treatment.

Conclusions

LSG might be an effective way to cure obesity-related HTG-induced AP since it prevents the recurrence of this disease. Further randomized studies will be needed to standardize this way of treatment.

     

Incidence,Indications, and Predictive Factors for ICU Admission in Elderly,High-Risk Patients Undergoing Laparoscopic Sleeve Gastrectomy

Background

Obesity affects the elderly, leading to increased prevalence of age- and obesity-associated comorbidities. There are no guidelines for indications and risk assessment for the elderly undergoing bariatric surgery.

Objectives

To determine the incidence, indications, and outcomes of planned ICU admission in elderly, high-risk patients after laparoscopic sleeve gastrectomy (LSG) and to assess if preoperative risk factors for planned postoperative ICU admission in elderly patients undergoing LSG could be predicted preoperatively.

Methods

Retrospective review of prospectively collected data for all patients aged ≥?60 years who underwent LSG (2011–2016) at Hamad General Hospital in Qatar.

Results

We followed up 58 patients aged 60–75 years for 28?±?17 months. About 77.6% of patients were in the intermediate-risk group of the Obesity Surgery Mortality Risk Score (OS-MRS). Fourteen patients (24%) required ICU admission for 2?±?1.2 days; all patients belonged to the American Society of Anesthesiologists (ASA) III class and intermediate to high risk on OS-MRS. There were no reported mortalities. The mean body mass index (BMI) decreased from 49?±?10.6 to 37.6?±?10.1 kg/m². The number of patient comorbidities (OR, 1.43; 95% CI, 1.03–1.99) and the diagnosis of obstructive sleep apnea (OSA; OR, 7.8; 95% CI, 1.92–31.68) were associated with planned ICU admission.

Conclusion

Elderly patients undergoing LSG usually have excellent postoperative course despite the associated high risk and the required ICU admission. The number of comorbidities, diagnosis of OSA, and ASA score are possible clinically significant predictive factors for the need of post-LSG ICU admission.

     

Role of Percutaneous Glue Treatment After Persisting Leak After Laparoscopic Sleeve Gastrectomy

Background

Over the years, many treatment modes have been attempted for gastrocutaneous fistula (GCF) after laparoscopic sleeve gastrectomy (LSG). Minimally invasive techniques for GCF treatment include stent placement and radiological percutaneous glue treatment (GT).

Material and Method

Ten patients underwent a radiological acrylate mixed with contrast medium GT combined or not with other treatment strategies such as relaparoscopy, ultrasound, or computerized tomography scan (CT scan)-guided drain and endoscopic stent placement.

Results

Ten patients (mean age 47.1 years, range 64–29) were treated by percutaneous injection of glue after LSG leak. Body mass index (BMI) was 42.2 kg/m²?±?6.7 at the time of LSG surgery. Mean time between LSG and leak diagnosis was 12 days (range 4–31 days). GT was only effective when performed after endoscopic stent placement (80 % resolution). With this regimen, five patients required a laparoscopic Roux limb placement. All fistulas eventually healed a mean of 75 days (range 29–293 days) after GCF diagnosis.

Conclusions

Percutaneous glue treatment alone does not seem to provide adequate results. Stenting previous to the glue treatment allows for better results.

     

Comparison of Outcomes Between Laparoscopic Roux-en-Y Gastric Bypass and Sleeve Gastrectomy in a Lebanese Bariatric Surgical Practice

Purpose

Long-term studies on the outcomes of bariatric surgery are still limited in the Middle East. The aim of this study is to compare the outcomes of laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) up to 5 years of follow-up.

Materials and Methods

A retrospective analysis of patients who underwent LRYGB and LSG was performed. The primary outcome was weight loss. Postoperative complications, operative time, and hospital length of stay were secondary outcomes.

Results

Four hundred patients underwent primary LSG and 175 patients underwent LRYGB between 2008 and 2013. Follow-up rates at 5 years were around 60%. Percent total weight loss was similar after 3, 4, and 5 years in both groups, averaging around 28%. Mean percentage of excess weight loss (%EWL) at 5 years was 72.0 ± 31.0% in the LSG group vs. 63.0 ± 21.0% in the LRYGB group (p = 0.03). Patients undergoing LRYGB had a significantly longer operative time as well as a longer hospital stay. No significant difference was found in the rates of short- and long-term complications between the two groups. However, patients undergoing LRYGB were more likely to develop small intestinal obstruction and iron-deficiency anemia.

Conclusions

Both LSG and LRYGB result in satisfactory weight loss within 5 years. Patients’ comorbidities and potential risks must be included in the choice of the appropriate bariatric procedure. LSG appears to give durable weight loss with less risk of major long-term complications.

     

Morbidity Rates and Weight Loss After Roux-en-Y Gastric Bypass,Sleeve Gastrectomy,and Adjustable Gastric Banding in Patients Older Than 60 Years old: Which Procedure to Choose?

Background

As life expectancy increases, more elderly patients fit into the criteria for bariatric procedures. The aim of our study is to evaluate and compare the safety and efficacy of Roux-en-Y gastric bypass (RYGB), laparoscopic sleeve gastrectomy (LSG), and laparoscopic adjustable gastric banding (LAGB) in patients older than 60.

Material and Methods

Between January 2005 and December 2013, 68 LAGB, 73 LSG, and 212 RYGB patients were 60 years or older at the time of primary procedure. A retrospective review was performed in these patients.

Results

Mean age and body mass index (BMI) was 62.7?±?2.2, 64.1?±?2.9, and 62.6?±?2.3 years and 42.7?±?5.6, 44.0?±?7.0, and 45.2?±?6.7 kg/m² for LAGB, LSG, and RYGB at the time of procedure, respectively.Seven (10.3 %) patients from the LAGB, 3 (4.1 %) from the LSG, and 29 (13.8 %) from the RYGB group required readmissions. Reoperation rate was 10.3, 1.4, and 9.5 % in LAGB, LSG, and RYGB, respectively. The difference in reoperation rates was statistically significant (p?<?0.03) while that in readmission rates was not (p?>?0.58). Procedure-related mortality rate was 1.4 % in the RYGB group, while no mortality was observed in LSG and LAGB groups. At 6, 12, and 18 months postoperatively, mean percentage of excess weight loss were highest in the RYGB group, followed by LSG and LAGB group (p?<?0.01). Mean number of comorbidities at the last follow-up significantly decreased in LSG and RYGB patients.

Conclusions

LSG showed the lowest readmission and reoperation rate, and RYGB patients had the highest mortality rate. Weight loss and comorbidity resolution were effectively achieved in RYGB and LSG patients.

     

Cost analysis of leak after sleeve gastrectomy

Background

Leaks after laparoscopic sleeve gastrectomy (LSG) are serious complications of this procedure. The objective of the present study was to evaluate the costs of leaks after LSG.

Setting

Private hospital, France.

Methods

A retrospective analysis was conducted on a prospective cohort of 2012 cases of LSG between September 2005 and December 2014. Data were collected on all diagnostic and therapeutic measures necessary to manage leaks, ward, and intensive care unit (ICU) length of stay. Additional outpatient care was also analyzed.

Results

Twenty cases (0.99%) of gastric leak were recorded. Fifteen patients had available data for cost analysis. Of these, 13 patients were women (86.7%) with a mean age of 41.4 years (range 22–61) and mean BMI of 43.2 kg/m² (range 34.8–57.1). The leaks occurred after 7.4 days (±2.3) postoperatively. Only one gastric leak was recorded for the last 800 cases in which absorbable staple line reinforcement was used. Mean intra-hospital cost was 34398 € (range 7543–91,632 €). Prolonged hospitalization in ICU accounted for the majority of hospital costs (58.9%). Mean additional outpatient costs for leaks were 41,284 € (range 14,148–75,684€).

Conclusions

Leaks after LSG are an expensive complication. It is therefore important to take all necessary measures to reduce their incidence. Our data should be considered when analyzing the cost effectiveness of staple line reinforcement usage.

     

Role of ursodeoxycholic acid in the prevention of gallstone formation after laparoscopic sleeve gastrectomy

Purpose

Postoperative cholelithiasis (CL) is a latent complication of bariatric surgery. The aim of this study was to evaluate the role of ursodeoxycholic acid (UDCA) in the prevention of CL after laparoscopic sleeve gastrectomy (LSG).

Methods

This was a retrospective analysis of the prospectively collected data of patients with morbid obesity who underwent LSG. Patients were subdivided into two groups: Group I, which did not receive prophylactic treatment with UCDA after LSG; and Group II, which received UCDA therapy for 6 months after LSG. Patients’ characteristics, operation duration, weight loss data, and incidence of CL at 6 and 12 months postoperatively were collected.

Results

A total of 406 patients (124 males, 282 females) with a mean age of 32.1 ± 9.4 years were included. The mean baseline body mass index (BMI) was 50.1 ± 8.3 kg/m². Group I comprised 159 patients, and Group II comprised 247 patients. The two groups showed comparable demographics, % excess weight loss (EWL), and decrease in BMI at 6 and 12 months after LSG. Eight patients (5%) developed CL in Group I, whereas no patients in Group II did (P = 0.0005). Preoperative dyslipidemia and rapid loss of excess weight within the first 3 months after LSG were the risk factors that significantly predicted CL postoperatively.

Conclusion

The use of UCDA effectively reduced the incidence of CL after LSG in patients with morbid obesity. Dyslipidemia and rapid EWL in the first 3 months after LSG significantly predisposed patients to postoperative CL.

     

Increased Metabolic Benefit for Obese,Elderly Patients Undergoing Roux-en-Y Gastric Bypass vs Sleeve Gastrectomy

Purpose

We sought to assess outcomes of laparoscopic sleeve gastrectomy (LSG) vs laparoscopic Roux-en-Y gastric bypass (LRYGB) in a cohort of morbidly obese, elderly patients.

Materials and Methods

Retrospective review was conducted of all patients age 60 years or greater undergoing LSG or LRYGB at our institution between 2007 and 2014.

Results

A total of 134 patients who underwent LSG (n = 65) or LRYGB (n = 69) were identified. Groups were similar with respect to age (64 years, range 60–75 years), BMI (44.0 ± 6.1), and ASA score (91% ≥ ASA 3). There were no differences in major post-operative complications (3, 4.7% LSG vs 4, 5.8% LRYGB, p = 0.75). Median follow-up was 39 months (IQR 14–64 months) with no patients lost to follow-up. Patients undergoing LRYGB had improvement in each of diabetes mellitus 2 (DM2), hypertension (HTN), hyperlipidemia (HL), and gastroesophageal reflux disease (GERD) as well as a significant decrease in insulin use (16/47, 34.0% pre-operatively vs 7/47, 15.2% post-operatively; p = 0.03). Patients undergoing LSG had improvement in DM2 and HTN but not in HL or GERD; there was no reduction in insulin dependence. Weight loss was not significantly different between groups; mean percent total weight loss at 36 months was 26.9 ± 9.0% in the LSG group and 23.9 ± 9.3% in the LRYGB group, p = 0.24.

Conclusions

Both LSG and RYGB can be safely performed on morbidly obese, elderly adults. At intermediate follow-up, there is an increased metabolic benefit for elderly patients undergoing LRYGB over LSG.

     

Endoscopic Sleeve Gastroplasty,Laparoscopic Sleeve Gastrectomy,and Laparoscopic Band for Weight Loss: How Do They Compare?

Background

Endoscopic sleeve gastroplasty (ESG) is a novel endobariatric procedure. Initial studies demonstrated an association of ESG with weight loss and improvement of obesity-related comorbidities. Our aim was to compare ESG to laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB).

Methods

We included 278 obese (BMI > 30) patients who underwent ESG (n = 91), LSG (n = 120), or LAGB (n = 67) at our tertiary care academic center. Primary outcome was percent total body weight loss (%TBWL) at 3, 6, 9, and 12 months. Secondary outcome measures included adverse events (AE), length of stay (LOS), and readmission rate.

Results

At 12-month follow-up, LSG achieved the greatest %TBWL compared to LAGB and ESG (29.28 vs 13.30 vs 17.57%, respectively; p < 0.001). However, ESG had a significantly lower rate of morbidity when compared to LSG or LAGB (p = 0.01). The LOS was significantly less for ESG compared to LSG or LAGB (0.34 ± 0.73 vs 3.09 ± 1.47 vs 1.66 ± 3.07 days, respectively; p < 0.01). Readmission rates were not significantly different between the groups (p = 0.72).

Conclusion

Although LSG is the most effective option for weight loss, ESG is a safe and feasible endobariatric option associated with low morbidity and short LOS in select patients.

     

Food Intake and Changes in Eating Behavior After Laparoscopic Sleeve Gastrectomy

Background

Laparoscopic sleeve gastrectomy (LSG) results in reduced calorie intake and weight loss. Whether patients consume the same types of food before and after surgery or whether they reduce the volume and calorie density of the foods they consume remains unknown.

Objectives

The aim of this prospective study was to evaluate the changes in daily caloric and macronutrient intake after LSG and the relation between changes of taste and food tolerance over 2 years.

Methods

Thirty morbidly obese patients with median body mass index (BMI) of 43.9 kg/m² (39.5–57.3) were prospectively enrolled prior to LSG. Weight, BMI, %EWL, weight loss percentage (%WL), and daily intake were evaluated preoperatively at 1, 3, 6, 12, and 24 months after surgery along with a questionnaire evaluating food choices, quality of eating, tolerance of certain types of food, frequency of vomiting, and changes in taste.

Results

The median %EWL and %WL at 12 and 24 months was 65 % (33.9–93.6 %), 27.3 % (14.2–45.5 %) and 71.5 % (39.6–101.1 %), 31 % (19.1–50.3 %) respectively. Six months after surgery, the daily caloric intake reduced by 68 % and the reduction was maintained until 24 months. The median score of the eating questionnaire was 18 (10–27) at 6 months, 22 (16–26) at 12 months, and 23 (10–27) at 24 months, suggesting that the quality of nutrition improved over time. At 6, 12, and 24 months, 75 % of the patients reported changes in taste with reduced interest in sweets, high fat food, and alcoholic drinks. However, at 24 months, 20 % of patients reported a heightened interest in sweets compared to 12 months previously.

Conclusions

LSG reduced calorie intake both through volume of food and the calorie density of the food consumed. The mechanisms for the changes in food preferences may involve both unconditioned and conditioned effects. The influence of dietary counseling on learning which foods are consumed still requires further exploration.

     

Weight Loss and Comorbidity Resolution 3 Years After Bariatric Surgery—an Indian Perspective

Introduction

Bariatric surgery has seen a sharp rise in India in the last decade. India is one of the 10 most obese nations of the world, ranking second in number of type 2 diabetics.

Aims

To evaluate clinical outcomes of bariatric surgery after 3 years of follow-up in terms of weight loss, co-morbidity resolution, complaints of gastroesophageal reflux disease and weight regain.

Methodology

All patients who underwent bariatric surgery from January to December 2013 with a minimum follow-up of 3 years were included in the study. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically.

Results

One hundred seventy-eight patients (157 lap. sleeve gastrectomy and 21 patients lap. RYGB) completed 3 years of follow-up. In the LSG group, patients had a pre-operative BMI 44.8?±?8.33 kg/sq. m (mean ± S.D.) and excess body weight 52.3?±?23.0 kg. In the RYGB group, pre-operative BMI was 42.7?±?8.82 kg/sq. m and excess body weight 45?±?18.7 kg. In the LSG group, % excess weight loss (EWL) at 1 year was 87.6?±?24.4% and 3 years was 71.8?±?26.7%. In the RYGB group, % EWL at 1 year was 97.2?±?27.3% and at 3 years was 85.8?±?25.3%. Diabetes resolution was seen in 32 (80%) in LSG group and 11 (91.7%) in RYGB group (Figs. 1, 2, 3, and 4).

Conclusion

Our study reflects that there is no statistically significant difference between outcomes of sleeve gastrectomy and Roux-en-Y gastric bypass surgery in terms of weight loss and diabetes resolution at 3 years.

     

Investigating Nutritional Deficiencies in a Group of Patients 3 Years Post Laparoscopic Sleeve Gastrectomy

Background

Laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure has shown to be effective in achieving significant weight loss and resolving obesity-related co-morbidities. However, its nutrition consequences have not been extensively explored. This study aims to investigate weight loss and evolution of nutritional deficiencies in a group of patients 3 years post LSG.

Methods

Retrospective data of a group of patients, 3 years following LSG as a stand-alone procedure was collected. Data included anthropometry, nutritional markers (hemoglobin, iron studies, folate, calcium, iPTH, vitamins D, and B₁₂), and compliancy with supplementations.

Results

Ninety-one patients (male/female; 28:63), aged 51.9?±?11.4 years with a BMI of 42.8?±?6.1 kg/m² were identified to be 3 years post LSG. Percentage of weight loss at 1 and 3 years post-operatively was 29.8?±?7.0 and 25.9?±?8.8 %, respectively. Pre-operatively, the abnormalities included low hemoglobin (4 %), ferritin (6 %), vitamin B₁₂ (1 %), vitamin D (46 %), and elevated iPTH (25 %). At 3 years post-operatively, the abnormal laboratory values included low hemoglobin (14 % females, P?=?0.021), ferritin (24 %, P?=?0.011), vitamin D (20 %, P?=?0.018), and elevated iPTH (17 %, P?=?0.010). Compliancy with multivitamin supplementation was noted in 66 % of patients.

Conclusion

In these patients, LSG resulted in pronounced weight loss at 1 year post-operatively, and most of this was maintained at 3 years. Nutritional deficiencies are prevalent among patients prior to bariatric surgery. These deficiencies may persist or exacerbate post-operatively. Routine nutrition monitoring and supplementations are essential to prevent and treat these deficiencies.

     

Results of Laparoscopic Sleeve Gastrectomy in 541 Consecutive Patients with Low Baseline Body Mass Index (30–35 kg/m<Superscript>2</Superscript>)

Background

Laparoscopic sleeve gastrectomy (LSG) is currently the leading bariatric procedure and targets, among other obesity classes, patients with BMI 30–35 kg/m², which are reaching alarming proportions.

Methods

Between February 2010 and August 2015, data on 541 consecutive patients with BMI 30–35 kg/m² undergoing LSG were prospectively collected and analyzed.

Results

Mean age was 32?±?8 years (13–65) and 419 (77.4 %) were women. Preoperative weight was 92.0?±?8.8 kg (65–121) and BMI was 32.6?±?1.5 kg/m² (30–35). Comorbidities were detected in 210 (39 %) patients. Operative time was 74?±?12 min (40–110) and postoperative stay was 1.7?±?0.22 days (1–3). There were no deaths, leaks, abscesses or strictures and the rate of hemorrhage was 1.2 %. At 1 year, 98 % were followed and BMI decreased to 24.7?±?1.6, the percentage of total weight loss (% TWL) was 24.1?±?4.7 while the percentage of excess BMI loss (%EBMIL) reached 106.1?±?24.1. At 5 years, 76 % of followed patients achieved a ≥50 % EBMIL.

Conclusion

With appropriate surgical expertise, LSG in patients with BMI 30–35 kg/m² achieved excellent outcomes with a zero fistula rate.

     

Fully Ambulatory Laparoscopic Sleeve Gastrectomy: 328 Consecutive Patients in a Single Tertiary Bariatric Center

Background

Laparoscopic sleeve gastrectomy (LSG) is becoming one of the most popular bariatric procedures because of its short operative time, good resolution of comorbidities, excellent weight loss, and low complications rate. However, the safety of LSG as a day-surgery procedure has not yet been widely documented.

Methods

A retrospective analysis of a prospectively collected bariatric database, in a single institution, between August 2012 and February 2015, yielded 980 patients who underwent LSG; 328 patients (33.5 %) responded to established criteria and were operated on a 1-day surgery basis (length of stay?<?12 h).

Results

There were 258 (78 %) primary LSG and 70 revisional LSG (22 %) performed on 284 females and 44 males, with a mean age (±SD) of 38?±?9 years. Mean (±SD) preoperative body mass index (BMI) was 45?±?6 kg/m². Operative time was 68?±?17 min (mean?±?SD). There were no deaths. A total of 322 patients (98.2 %) were discharged home the day of surgery. There were 6 (1.8 %) unplanned overnight hospitalization, and 28 patients (8.5 %) were readmitted between days 1 and 30. Most patients (25/34, 73 %) were hospitalized for minor problems, such as pain, nausea, and/or vomiting. There were two cases of (0.6 %) gastric staple line leaks, three (0.9 %) of intra-abdominal hematomas, two (0.6 %) of pneumonia, one (0.3 %) of acute pancreatitis, and one (0.3 %) of urinary tract infection. All patients recovered well.

Conclusions

LSG can be performed as an outpatient procedure in selected patients, with acceptable results in terms of retention, readmission, and complication rates.

     

Laparoscopic Ileal Interposition with Diverted Sleeve Gastrectomy Versus Laparoscopic Transit Bipartition with Sleeve Gastrectomy for Better Glycemic Outcomes in T2DM Patients

Background

Metabolic procedures provide better outcomes for obese patients with type 2 diabetes mellitus. Our aim was to compare the glycemic regulation in patients that have undergone the laparoscopic ileal interposition with diverted sleeve gastrectomy (II-DSG), laparoscopic transit bipartition with sleeve gastrectomy (TB-SG), and laparoscopic sleeve gastrectomy (LSG) throughout a 12-month follow-up period retrospectively.

Methods

This study considered patients with T2DM who underwent metabolic procedures. The postoperative changes in the glucose, C-peptide, HbA1c, HOMA-IR, insulin, cholesterol, body mass index, and total weight loss (TWL) were compared retrospectively. The intended outcome was to reach a long lasting fasting blood glucose (FBG) <126 mg/dl. A multivariate regression analysis was applied to define the predictive markers in glucose regulation.

Results

Present study consisted of 83 patients with a mean age of 47.25 ± 6.58 years, mean preoperative BMI of 37.36 ± 2.71 kg/m², and mean outcomes in the HbA1C and FBG of 9.05 ± 1.33% and 237 ± 15 mg/dl, respectively. There were similar correlations in BMI and total weight loss (TWL). At 12-month follow up period, compared to LSG group, TB-SG and II-DSG groups have higher remission proportions (35.3, 67.9, 54.7, respectively, p < 0.05) with similar TWL% (22.35, 27.14, 23.16%) outcomes. The II-DSG and TB-SG results drew closer together toward the end of this study interval unlike the LSG group.

Conclusion

Our results showed that II-DSG and TB-SG ensured significant regression rates during the follow-up period. Since the TB-SG achieved these outcomes by finite anastomoses and intervening segments, it was considered to be a superior procedure compared to II-DSG and LSG procedures.

     

Metabolic Parameters,Weight Loss,and Comorbidities 4 Years After Roux-en-Y Gastric Bypass and Sleeve Gastrectomy

Background

Sleeve gastrectomy (LSG) is now the predominant bariatric surgery performed, yet there is limited long-term data comparing important outcomes between LSG and Roux-en-Y gastric bypass (RYGB). This study compares weight loss and impact on comorbidities of the two procedures.

Methods

We retrospectively evaluated weight, blood pressure, hemoglobin A1c, cholesterol, and medication use for hypertension, diabetes, and hyperlipidemia at 1–4 years post-operatively in 380 patients who underwent RYGB and 334 patients who underwent LSG at the University of Michigan from January 2008 to November 2013. Follow-up rates from 714 patients initially were 657 (92%), 556 (78%), 507 (71%), and 498 (70%) at 1–4 years post-operatively.

Results

Baseline characteristics were similar except for higher weight and BMI in LSG. There was greater weight loss with RYGB vs. LSG at all points. Hemoglobin A1c and total cholesterol improved more in RYGB vs. LSG at 4 years. There was greater remission of hypertension and discontinuation of all medications for hypertension and diabetes with RYGB at 4 years.

Conclusions

Weight loss, reduction in medications for hypertension and diabetes, improvements in markers of diabetes and hyperlipidemia, and remission rates of hypertension were superior with RYGB vs. LSG 4 years post-operatively. Choice of bariatric procedures should be tailored to surgical risk, comorbidities, and weight loss goals.

     

Changes in Bile Acid Profile After Laparoscopic Sleeve Gastrectomy are Associated with Improvements in Metabolic Profile and Fatty Liver Disease

Background

Bile acids (BA) modulate lipid and glucose metabolism in a feedback loop through production of fibroblast growth factor (FGF) 19 in the terminal ileum. Changes in BA after bariatric surgery may lead to improvements in the metabolic syndrome, including fatty liver disease. This study investigated the relationship between BA and metabolic and inflammatory profiles after laparoscopic sleeve gastrectomy (LSG).

Methods

Patients undergoing LSG had fasting blood samples taken pre-operatively and 6 months post-surgery. Liver injury was measured using cytokeratin (CK) 18 fragments. BA were measured using liquid chromatography tandem-mass spectrometry. FGF-19 was measured using enzyme-linked immunosorbent assay.

Results

The study included 18 patients (12 females), with mean age 46.3 years (SEM?±?2.9) and BMI 60.1 kg/m² (±2.6). After 6 months, patients lost 39.8 kg (±3.1; p?<?0.001). Fourteen patients (78 %) had steatosis. FGF-19 increased from median 128.1 (IQR 89.4–210.1) to 177.1 (121.8–288.9, p?=?0.045) at 6 months. Although total BA did not change, primary glycine- and taurine-conjugated BA, cholic acid decreased, and secondary BA, glycine-conjugated urodeoxycholic acid increased over the study period. These changes are associated with reduction in insulin resistance, pro-inflammatory cytokines and CK-18 levels.

Conclusions

The profile of individual BA is altered after LSG. These changes occur in the presence of reductions in inflammatory cytokines and markers of liver injury. This study supports evidence from recent animal models that LSG may have an effect on fatty liver through changes in BA metabolism.

     

Impact of the Surgical Experience on Leak Rate After Laparoscopic Sleeve Gastrectomy

Introduction

Laparoscopic sleeve gastrectomy (LSG) has become one of the most commonly performed bariatric procedures, largely due to several advantages it carries over more complex bariatric procedures. LSG is generally considered a straightforward procedure, but one of the major concerns is a staple line leak.

Objective

The objectives of this study are to evaluate the correlation between surgeon’s experience and leak rate and to assess the different risk factors for developing a gastric leak after LSG.Setting: Private hospital, France.

Methods

The analysis of a single surgeon’s yearly leak rate since the introduction of LSG for possible risk factors was done.

Results

A total of 2012 LSGs were performed in between September, 2005 and December, 2014. Twenty cases (1 %) of gastric leak were recorded. Of these, 17 patients were women (94.4 %) with a mean age of 39.4 years (range 22–61) and mean body mass index (BMI) 41.2 kg/m² (range 34.8–57.1). On a yearly basis, the leak rate was 4.8 % (2006), 5.7 % (2007), 0 (2008), 2.6 % (2009), 2 % (2010), 0.8 % (2011), 0.6 % (2012), 0.2 % (2013), and 0 (2014). In the first 1000 cases (group A), there were 18 cases of gastric leak and in the last 1000 cases, there were 800 with GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement (group B) 2 cases of gastric leak (p?=?0.009). A revisional LSG, 395 patients after gastric banding and 61 patients re-sleeve gastrectomy, was performed in 456 cases (22.7 %). There were 3 cases of leak (0.65 %). There were two deaths.

Conclusion

LSG can be performed with a low complication rate. This large series of a single surgeon’s experience demonstrated that the leak rate after LSG could be significantly decreased over time with changes in techniques.
