Laparoscopic Sleeve Gastrectomy for Late Adolescent Population

Background

Morbid obesity prevalence is rapidly increasing among adolescents worldwide. Evidence is mounting that bariatric surgery is the only reliable method for substantial and sustainable weight loss; however, the debate continues with regard to the optimal surgical procedure for adolescents and to the age limit when bariatric surgery should be proposed.

Methods

A retrospective multicenter review included all late adolescent patients (<20 years old) who underwent sleeve gastrectomy from 2005 to 2012 in three French bariatric centers: Montpellier University Hospital, Casamance Private Hospital, and Noumea Regional Hospital. Collected data included age, sex, body mass index (BMI), intraoperative complications, length of hospital stay, operative morbidity, the need for reoperation, and percentage of excess weight loss (% EWL) at 6 months, 1 year, and 2 years postoperatively.

Results

A total of 61 adolescent patients have undergone sleeve gastrectomy. Of these, 42 were women and 19 were men. The mean preoperative weight was 132.8 kg (range 90–217 kg) with a BMI of 46.7 (range 35.5–68.7). Seventeen patients (27.9 %) were superobese (BMI?>?50), and seven patients (11.5 %) were supersuperobese (BMI?>?60). All the procedures were performed by laparoscopy with no intraoperative complications. The mean hospital stay was 4.6 days. Four major complications were recorded: one staple line leak, two hematomas, and one case of pneumonia. No mortality was recorded. The % EWL at 6 months, 1 year, and 2 years postoperatively was 48.1 % (±17.9 %), 66.7 % (±19.5 %), and 78.4 % (±16.8 %), respectively, for a follow-up of 93.4, 81.9, and 52.4 %, respectively. There were 18 patients (29.5 %) with identified comorbid conditions: 10 cases of sleep apnea, 7 cases of hypertension, and 1 case of type 2 diabetes, with a resolution rate of 77.8 %.

Conclusions

Laparoscopic sleeve gastrectomy may be advantageous for this age group, since it involves neither foreign body placement nor lifelong malabsorption. Laparoscopic sleeve gastrectomy represents an attractive bariatric procedure for adolescent patients, more efficient than gastric banding and with less morbidity compared to gastric bypass.     

Gastric Leak After Laparoscopic Sleeve Gastrectomy

Sleeve gastrectomy is a recently developed technique for treating morbid obesity. Since it is a simple procedure, the number of surgeons using it has grown in recent years. The patients who present fistulas after surgery often undergo a harrowing postoperative period as well as increased morbidity and mortality. Our aim was to assess the incidence, causes, diagnosis, management, and prevention of leaks after sleeve gastrectomy.     

Mid-term Results of Laparoscopic Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Adolescent Patients

The prevalence and severity of obesity in children and adolescents has been increasing in recent years at an unprecedented rate. Morbidly obese children will almost certainly develop severe comorbidities as they progress to adulthood, and bariatric surgery may provide the only alternative for achieving a healthy weight. The aim of this study was to assess the long-term outcomes and safety of laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) as new treatment modalities for morbidly obese adolescents. We conducted a retrospective review of a prospectively collected database of all adolescent patients who underwent LSG and RYGB under IRB protocol at the Bariatric and Metabolic Institute in Cleveland Clinic Florida between 2002 and 2011. Patients were also contacted by phone, adhering to HIPAA regulations, and were asked to answer a survey. Eighteen adolescents had a bariatric procedure performed at this institution. The mean age was 17.5 years, the average weight was 293.1 lbs, and the average BMI was 47.2 kg/m². The mean follow-up period consisted of 55.2 months. The postoperative weight at 55 months follow-up was 188.4 lbs and average BMI was 30.1 kg/m². Fifteen of the patients were available for follow-up. Thirteen out of 16 (81 %) comorbidities in patients available for follow-up were in remission following rapid weight loss. The long-term follow-up and perioperative morbidity shown in this study suggest that LSG and LRYGB appear to be safe and effective operations in morbidly obese adolescents.     

Laparoscopic Conversion of Gastric Bypass Complication to Sleeve Gastrectomy: Technique and Early Results

Background

Laparoscopic gastric bypass is a commonly performed bariatric surgery for the treatment of morbid obesity. Revision surgery for patients who have gastric bypass complications is a challenge for bariatric surgeon. Our aim is to present the early results of the conversions of gastric bypass complications to sleeve gastrectomies.

Methods

From January 2001 to April 2015, 49 of 2382 gastric bypasses underwent revisional surgery to convert gastric bypasses to sleeve gastrectomies. The demographic data, surgical parameters, and outcomes were studied.

Results

The mean age of the study group was 35.0 years (range 20 to 55), and the average body mass index (BMI) prior to the reoperation was 25.3 kg/m². Seven patients had previous laparoscopic Roux-en-Y gastric bypasses (LRYGBs), and 42 had laparoscopic single anastomosis (mini-) gastric bypasses (LSAGBs). The main reasons for the revisions were malnutrition (58 %), weight regain (10 %), intolerance (18 %), and others (14 %). The revisional surgeries had longer operative times, greater blood loss, and longer flatus passage times than the primary gastric bypass surgeries. Four patients (8.1 %) developed major complications during revisional surgery, including three (6.1 %) cases of leakage and one (2.0 %) case of internal bleeding. No mortality was noted. After conversion to sleeve gastrectomy, the body weights of the patients remained stable, and all patients improved in terms of malnutrition, including anemia, hypoalbuminemia, and secondary hyperparathyroidism.

Conclusions

Conversion to sleeve gastrectomy is an effective and safe option for patients with gastric bypass complications. The conversions to sleeve gastrectomy resulted in significant improvements in malnutrition and maintained weight loss at the early follow-ups.

     

Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass

Introduction

A subset of patients undergoing laparoscopic sleeve gastrectomy (SG) require eventual conversion to Roux-en-Y gastric bypass (RYGB) due to complications from SG or to enhance weight loss. The aim of this study is to characterize the indications for conversion and perioperative outcomes in a large cohort of these patients at a single institution.

Methods

Patients who underwent revisional surgery to convert SG to RYGB at our institution from January 2008 through January 2017 were retrospectively reviewed.

Results

Eighty-nine patients with previous SG underwent conversion to RYGB as part of a planned two-stage approach to gastric bypass (n?=?36), for weight recidivism (n?=?11), or for complications related to SG (n?=?42). Complications from SG that warranted conversion included refractory GERD (40.5%), sleeve stenosis (31.0%), gastrocutaneous (16.7%), or gastropleural (7.1%) fistula, and gastric torsion (4.1%). The mean (SD) age was 47.2 years (11.4 years) and median BMI at the time of revision was 43.2 kg/m². A laparoscopic approach was successfully completed in 76 patients (85.4%), with an additional of four completed robotically (4.5%). The median length of stay was 3 days. Twenty-eight patients (31.5%) had complications which included surgical site infection (20.2%), re-operation (6.7%), anastomotic stricture (3.4%), and one pulmonary embolism. There were no mortalities with a median follow-up of 15 months.

Conclusions

Conversion of SG to RYGB is safe and technically feasible when performed for complications of SG or to enhance weight loss. This operation can be successfully performed laparoscopically with a low rate of conversion and reasonable complication profile.

     

Laparoscopic Total Gastrectomy with Roux-Y Esophagojejunostomy for Chronic Gastric Fistula After Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is a restrictive operation with hormonal elements that is rapidly gaining popularity. The most feared complication of the procedure is a staple line leak. The treatment of staple line leakage depends on timing and clinical and anatomical considerations. If leakage persists and transforms into a chronic fistula, a definitive surgical procedure is required. In cases where the fistula originates close to the esophagogastric junction, the surgical possibilities are limited and one treatment option is total gastrectomy with esophagojejunal anastomosis. We report a case series of four patients with chronic fistulae, who failed conservative treatment and required total gastrectomy. Their average length of hospital stay was 8.7 days (range, 5–15 days), without conversions, leaks, or other complications. In experienced hands, total gastrectomy is feasible by laparoscopic techniques and should be performed soon after the fistula is established.     

Risk Factors for Prolonged Length of Hospital Stay and Readmissions After Laparoscopic Sleeve Gastrectomy and Laparoscopic Roux-en-Y Gastric Bypass

Background

Laparoscopic sleeve gastrectomy (LSG) and laparoscopic gastric bypass (LRYGB) are most commonly performed bariatric procedures. Laparoscopic approach and enhanced recovery after surgery (ERAS) protocols managed to decrease length of hospital and morbidity. However, there are patients in whom, despite adherence to the protocol, the length of stay (LOS) remains longer than targeted. This study aimed to assess potential risk factors for prolonged LOS and readmissions.

Methods

The study was a prospective observation with a post-hoc analysis of bariatric patients in a tertiary referral university teaching hospital. Inclusion criteria were undergoing laparoscopic bariatric surgery. Exclusion criteria were occurrence of perioperative complications, prior bariatric procedures, and lack of necessary data. The primary endpoints were the evaluations of risk factors for prolonged LOS and readmissions.

Results

Median LOS was 3 (2–4) days. LOS > 3 days occurred in 145 (29.47%) patients, 79 after LSG (25.82%) and 66 after LRYGB (35.48%; p = 0.008). Factors significantly prolonging LOS were low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence to bariatric center. The risk of hospital readmission rises with occurrence of intraoperative adverse events and low oral fluid intake on the day of surgery on.

Conclusions

Risk factors for prolonged LOS are low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence. Risk factors for hospital readmission are intraoperative adverse events and low oral fluid intake on the day of surgery.

     

Laparoscopic Gastric Bypass Versus Laparoscopic Sleeve Gastrectomy as a Definitive Surgical Procedure for Morbid Obesity. Mid-Term Results

Background

Laparoscopic sleeve gastrectomy (LSG) has been gaining acceptance because it has shown good short- and mid-term results as a single procedure for morbid obesity. The aim of this study was to compare short- and mid-term results between laparoscopic Roux-en-Y gastric bypass (LRYGB) and LSG.

Methods

Observational retrospective study from a prospective database of patients undergoing LRYGB and LSG between 2004 and 2011, where 249 patients (mean age 44.7 years) were included. Patients were followed at 1, 3, 6, 12, and 18 months, and annually thereafter. Short- and mid-term weight loss, comorbidity improvement or resolution, postoperative complications, re-interventions, and mortality were evaluated.

Results

One hundred thirty-five LRYGB and 114 LSG were included. Significant statistical differences between LRYGB and LSG were found in operative time (153 vs. 93 min. p?<?0.001), minor postoperative complications (21.5 % vs. 4.4 %, p?=?0.005), blood transfusions (8.8 % vs. 1.7 %, p?=?0.015), and length of hospital stay (4 vs. 3 days, p?<?0.001). There were no differences regarding major complications and re-interventions. There was no surgery-related mortality. The percentage of excess weight loss up to 4 years was similar in both groups (66?±?13.7 vs. 65?±?14.9 %). Both techniques showed similar results in comorbidities improvement or resolution at 1 year.

Conclusions

There is a similar short- and mid-term weight loss and 1-year comorbidity improvement or resolution between LRYGB and LSG, although minor complication rate is higher for LRYGB. Results of LSG as a single procedure need to be confirmed after a long-term follow-up.     

Laparoscopic Roux-en-Y Gastric Bypass with Subtotal Gastrectomy

Laparoscopic gastric bypass is a common procedure for morbid obesity. After gastric bypass, the distal stomach is unavailable for surveillance. When a suspicious distal gastric lesion is present preoperatively, a distal subtotal gastrectomy may be needed. Herein we describe such a case performed laparoscopically. Laparoscopic gastric bypass with subtotal gastrectomy for morbid obesity should be considered for patients with suspicious distal gastric lesions.     

Laparoscopic Sleeve Gastrectomy with Duodenojejunal Bypass for Type 2 Diabetes Mellitus

Background

Laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB), which has been positioned as a novel bariatric procedure, is the combination of vertical sleeve gastrectomy and proximal intestinal bypass and is theoretically expected to have strong anti-diabetic effect. Also, preserving the pylorus, a physiological valve, leads to less occurrence of dumping syndrome and anastomotic stenosis which are often problematic after laparoscopic Roux-en-Y gastric bypass (LRYGB), a gold standard. The purpose of this study was to investigate the clinical effects of LSG-DJB on obese patients with type 2 diabetes mellitus (T2DM).

Methods

Consecutive 75 obese patients (female 44/male 31) associated with T2DM who underwent LSG-DJB and were followed up for at least 1 year were analyzed. The mean age was 45.5?±?8.6 years, and the mean preoperative body weight (BW) and body mass index (BMI) were 108.4?±?21.4 kg and 39.6?±?7.3 kg/m², respectively. The mean hemoglobin A1c (HbA1c) at the first visit was 9.0?±?1.9 %, and the duration of T2DM from diagnosis was 7.2?±?6.2 years. Thirty-six out of the 75 patients (48 %) were treated with insulin preoperatively. All patients were evaluated and managed under a strict multidisciplinary team approach. The follow-up rate at 1 year was 89 %.

Results

At 1 year, the mean BW and BMI significantly dropped to 74.6?±?16.9 kg and 27.5?±?5.7 kg/m², respectively. The mean percent of excess weight loss (%EWL) and percent of total body weight loss (%TWL) were 99.4?±?42.4 and 31.6?±?8.8 %, respectively. Consequently, 68.7 % of the patients achieved HbA1c less than 6 %, and 82.1 % of them achieved HbA1c less than 6.5 % without diabetes medications. Glycemic control of HbA1c less than 7 % was achieved in 91.0 % of the patients. The percentage of patients who satisfied the American Diabetes Association (ADA)-defined composite endpoints for cardiovascular disease (CVD) risk factor control increased from 0 % (at baseline) to 31 % (at 1 year). A meal tolerance test revealed significant reduction of glucose area under the curve (AUC) and increase of insulin AUC postoperatively.

Conclusions

LSG-DJB for obese patients with T2DM has strong anti-diabetic effect in the short-term; however, a larger number of patients with a longer follow-up period are needed for definitive conclusions.

     

Approach to Poor Weight Loss After Laparoscopic Sleeve Gastrectomy: Re-sleeve Vs. Gastric Bypass

Background

Laparoscopic sleeve gastrectomy (LSG) is increasing worldwide; however, long-term follow-up results included insufficient weight loss and weight regain. This study aims at assessing the outcomes of converting LSG to laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic re-sleeve gastrectomy (LRSG).

Methods

A total of 1300 patients underwent LSG from 2009 to 2012, of which 12 patients underwent LRYGB and 24 patients underwent LRSG in Al-Amiri Hospital alone. Data included length of stay, percentage excessive weight loss (EWL%), and body mass index (BMI).

Results

Twenty-four patients underwent conversion from LSG to LRSG, and 12 patients underwent conversion from LSG to LRYGB due to insufficient weight loss and weight regain. Eighty-five percent were females. The mean weight and BMI prior to LSG for the LRYGB and LRSG patients were 136.5 kg and 52, and 134 kg and 50, respectively. The EWL% after the initial LSG was 37.9 and 43 %, for LRYGB and LRSG, respectively. There were no complications recorded. Results of conversion of LSG to LRYGB involved a mean EWL% 61.3 % after 1 year (p value 0.009). Results of LRSG involved a mean EWL% of 57 % over interval of 1 year (p value 0.05). Comparison of the EWL% of LRYGB and LRSG for failed primary LSG was not significant (p value 0.097).

Conclusion

Following our algorithm, revising an LSG with an LRSG or LRYGB for poor weight loss is feasible with good outcomes. Larger and longer follow-up studies are needed to verify our results.

     

Laparoscopic Sleeve Gastrectomy as an Alternative to Gastric Bypass in Patients with Multiple Intraabdominal Adhesions

Background Laparoscopic sleeve gastrectomy and its indications are currently being evaluated. The objective of this study was to show the preliminary results obtained with this technique indicated as an alternative to gastric bypass in patients with multiple intraabdominal adhesions, therefore preserving the benefits of the laparoscopic approach. Methods An analysis of all patients who underwent a laparoscopic sleeve gastrectomy for the above indication was done. Data included demographics, number of previous surgeries, operative time, morbidity, mortality, and %EWL at 3 and 6 months. Results Fifteen patients underwent laparoscopic sleeve gastrectomy as an alternative to gastric bypass because of multiple intraabdominal adhesions. No patient required conversion to an open procedure; morbidity was 6% with no mortality. %EWL at 3 months was 41% and at 6 months was 44%. Mean follow-up was 6 months. Conclusion In our initial experience, laparoscopic sleeve gastrectomy proved to be a safe and effective alternative to gastric bypass for patients with multiple intraabdominal adhesions.

Laparoscopic Sleeve Gastrectomy Versus Banded Roux-en-Y Gastric Bypass for Diabetes and Obesity: a Prospective Randomised Double-Blind Trial

Background

There are very few randomised, blinded trials comparing laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in achieving remission of type 2 diabetes (T2D), particularly silastic ring (SR)-LRYGB. We compared the effectiveness of (LSG) versus SR-LRYGB among patients with T2D and morbid obesity.

Methods

Prospective, randomised, parallel, 2-arm, blinded clinical trial conducted in a single Auckland (New Zealand) centre. Eligible patients aged 20–55 years, T2D of at least 6 months duration and BMI 35–65 kg/m² were randomised 1:1 to LSG (n = 58) or SR-LRYGB (n = 56) using random number codes disclosed after anaesthesia induction. Primary outcome was T2D remission defined by different HbA1c thresholds at 1 year. Secondary outcomes included weight loss, quality of life, anxiety and depressive symptoms, post-operative complications and mortality.

Results

Mean ± standard deviation (SD) pre-operative BMI was 42.5 ± 6.2 kg/m², HbA1c 63 ± 16 mmol/mol (30% insulin-treated, 28% had diabetes duration over 10 years). Proportions achieving HbA1c ≤ 38 mmol/mol, < 42 mmol/mol, < 48 mmol/mol and < 53 mmol/mol without diabetes medication at 1 year in SR-LRYGB vs LSG were 38 vs 43% (p = 0.56), 52 vs 49% (p = 0.85), 75 vs 72% (p = 0.83) and 80 vs 77% (p = 0.82), respectively. Mean ± SD % total weight loss at 1 year was greater after SR-LRYGB than LSG: 32.2 ± 7.7 vs 27.1 ± 7.5%, respectively (p < 0.001). Gastrointestinal complications were more frequent after SR-LRYGB (including 3 ulcers, 1 anastomotic leak, 1 abdominal bleeding). Quality of life and depression symptoms improved significantly in both groups.

Conclusion

Despite significantly greater weight loss after SR-LRYGB, there was similar T2D remission and psychosocial improvement after LSG and SR-LRYGB at 1 year.

Laparoscopic Sleeve Gastrectomy with Duodenojejunal Bypass: Technique and Preliminary Results

Background  

Obesity and metabolic disorders related to it have become a serious problem in Asia. Furthermore, gastric cancer in Asia is one of the frequent diseases on which to perform treatments. We introduced the technique of laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG/DJB) for patients with a risk of gastric cancer and compared the results of our initial series with those of other procedures.     

Gastric Stenosis After Laparoscopic Sleeve Gastrectomy: Diagnosis and Management

Purpose

The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication.

Methods

We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data.

Results

During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4 %); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1–114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2 %) after balloon dilatation (n?=?13) or insertion of a covered stent (n?=?2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8 %).

Conclusion

GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.

     

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.
