Radiology of Patients with Vertical Banded Gastroplasty

Background: The authors evaluated the usefulness of routine traditional radiology in the management of patients submitted to VBG. Methods: Radiological findings in 65 subjects who had undergone VBG were evaluated. Post-surgical clinical and radiological examinations were performed 3 days, 1, 4 and 12 months after surgery. Upper GI symptoms, gastroesophageal imaging and 80% solid meal pouch emptying time were recorded. Results: The routine postoperative study, in the absence of clinical symptoms, showed no unsuspected complication in any patient, both in the early and in the late postoperative period. There was no significant correlation at 4 and 12 months between emptying time and duration of satiation, emptying time and percent excess weight loss (%EWL), and duration of satiation and %EWL. Conclusions: Traditional radiological studies can be safely omitted from both the immediate postoperative period and from the long-term follow-up in asymptomatic VBG patients. The studies were not helpful in understanding functional changes leading to weight loss after VBG.     

Technical Modification of Laparoscopic Vertical Banded Gastroplasty

Background: Technical improvements of laparoscopic bariatric procedures are important to minimize operative time and increase safety and simplicity. Methods: A modification is described of the "classic" Mason - MacLean vertical banded gastroplasty (VBG), performed by laparoscopy, with wedge resection of the gastric fundus, thus avoiding the time-consuming and technically difficult gastro-gastrostomy window. Results: The technique used was simple and safe, and required less operative time than the "classic" method, without serious intra- or postoperative complications. Weight loss in 18 patients who underwent the modified laparoscopic VBG and were followed-up for 1 year was equal to that achieved in patients who underwent openVBG at our Institution. Gastro-gastric fistula was not observed in upper GI barium studies performed 12 months postoperatively. Conclusion: The modified technique is preferable when lap-VBG is indicated for surgical treatment of morbidly obese patients.     

Dietary Changes after Vertical Banded Gastroplasty

Background: Gastric restriction surgery relies on obstruction to oral intake by formation of a gastric pouch. Therefore, the therapeutic effect is closely related to intolerance for different types of food, and an ingestion of an unbalanced diet. We investigated dietary changes after VBG and their associations with therapeutic success. Methods: 70 patients (4 men, 66 women, median age 32) with a median preoperative BMI of 44.6 were examined ≥ 3 years after VBG. Weight reduction, nutritional changes (type ofdiet,number of daily meals,amount of food that could be ingested, intolerance for different types of food, frequency of vomiting), satisfaction with results, and willingness to undergo the operation once again were investigated. Results: The average reduction of the BMI was 13, with sufficient weight loss in 80%. 36% were eating a solid, 43% a soft, and 21% a liquid diet. Weight reduction did not depend on the type of diet eaten but on the ingestion of sweets. 93% indicated they could take only small amounts of food. The average number of daily meals was 3. 76% reported an intolerance for some type of food (most often meat, fruit, or vegetable). Vomiting was the most common problem and occurred in 71%. 71% indicated a high level of satisfaction with the results of the operation, and 96% said they would undergo the operation again. Conclusions:The investigation demonstrated successful weight reduction despite dietary changes in 80% of patients after VBG. Weight reduction was not influenced by type of diet but depended on consumption of sweets.     

Laparoscopic Vertical Banded Gastroplasty: Early Experience

Background: The tremendous development of laparoscopic surgery in the last decade is being applied to bariatric surgery. Laparoscopic vertical banded gastroplasty (LVBG) is technically feasible by laparoscopy. Methods: From August 1998 to August 1999, 13 patients underwent LVBG. The technical difficulties are discussed. Results: Operating time ranged from 105 to 420 minutes. 11 patients have lost 45-55% of their original weight. Inserting an esophageal bougie no. 11 from the beginning of the operation and using the laparoscopic set-up described, made the procedure shorter, safer and easier for patients and surgeon. Conclusion: LVBG is technically feasible for the laparoscopic bariatric surgeon who is experienced in the handling and control of laparoscopic instruments and hand-eye coordination. The early results are satisfactory. Preoperative counseling is an integral step for the operation.     

Gastric Cancer Occurring After Vertical Banded Gastroplasty

A case of gastric cancer after vertical banded gastroplasty (VBG) is presented. A 44-year-old man presented with vomiting and weight loss 6 years after VBG. Endoscopy revealed a poorly differentiated gastric adenocarcinoma. The patient underwent a Whipple pancreaticoduodenectomy and received chemotherapy. He expired 6 months later. From our case and review of the literature, development of gastric cancer after VBG is very rare. The authors suggest that patients undergoing VBG be monitored by endoscopy after the operation.     

Open Versus Laparoscopic Vertical Banded Gastroplasty: A Randomized Controlled Double Blind Trial

Background:Vertical banded gastroplasty (VBG) is a frequently used surgical procedure for the treatment of morbid obesity. It can be done open (OVBG) or laparoscopic (LVBG). The aim of this double-blind randomized clinical trial was to compare the postoperative outcome and 1-year follow-up of 2 cohorts of patients who underwent either OVBG or LVBG. Patients and Methods: 30 patients with morbid obesity were randomized into 2 groups (14 OVBG and 16 LVBG). Pain intensity, analgesic requirements, respiratory function, and physical activity were blindly analyzed during the first 3 postoperative days. Complications, weight loss, and cosmetic results after 1 year follow-up were evaluated. Results: Both groups were highly comparable before surgery. Surgical time was longer in the laparoscopic procedure. Patients in this group required less analgesics during the first postoperative day.There was an earlier recovery in the expiratory and inspiratory forces, as well as faster recovery of physical activities in patients who underwent LVBG. Postoperative complications were more frequent in the open group. Excess body weight loss after 1 year was similar in both groups. Cosmetic results were significantly better in the laparoscopic group. Conclusions: LVBG had advantages over the open procedure in terms of analgesic requirements, respi function, postoperative recovery, and cosmetic results.     

Open vs Laparoscopic Vertical Banded Gastroplasty: A case control study with 1-year follow-up

Background: Vertical Banded Gastroplasty (VBG) is one of the most common bariatric operations. It can be performed by open or laparoscopic methods. The purpose of this study was to analyze and compare the 1-year results of 40 patients who underwent laparoscopic (20) and open (20). Methods: The initial 20 patients undergoing LaparoscopicVBG and the initial 20 patients in whom an Open VBG were performed in our Institution were comparatively evaluated. Demography, surgical details, complications, and 1-year weight loss were analyzed. Results: Both groups were highly comparable in terms of age, sex and body mass index. Laparoscopic VBG was a more prolonged procedure (median 4 hr) than the open VBG (median 3 hr). On the other hand, hospital stay was significantly shorter in the laparoscopic procedure (median 10 days for the open and 6 days for the laparoscopic). One year weight loss and complications were similar in both groups. Conclusions: Laparoscopic VBG is a safe procedure for the treatment of morbid obesity. This initial series shows comparable results.     

Breast Reconstruction Facilitated by Vertical Banded Gastroplasty

Background: Vertical banded gastroplasty (VBG) causes weight loss, which is often associated with redundant abdominal tissue. This redundant tissue can be used successfully for breast reconstruction or breast augmentation in case of mastectomy or ptotic hypotrophic breasts. Method: One patient with bilateral mastectomy is described in whom the weight fell from BMI 52 to BMI 26 after VBG, giving the patient an abdominal "apron", which facilitated bilateral breast reconstruction. Results: Bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction after weight reduction following VBG resulted in an esthetic pleasing result with additional correction of the cutis laxa abdominis. Conclusion: Autologous breast reconstruction can be performed safely with the methods used today, after successful weight loss following obesity surgery.     

Plasma Cholecystokinin Levels after Vertical Banded Gastroplasty: Effects of an Acidified Meal

Background: Although cholecystokinin (CCK) is involved in the short-term regulation of satiety, it has not been investigated in obese patients subjected to bariatric restrictive operations. Methods: 8 morbidly obese patients (BMI 49.1 ± 6.9), 7F and 1M, were investigated before and after vertical banded gastroplasty (VBG). 6 healthy lean volunteers served as the control group. CCK was determined (RIA) after an overnight fast and after the administration of an acidified (pH 3) liquid meal. Blood samples were taken 45 min before the meal, 5 min after it and then every 30 min for 3 hours. Results: There were no differences between groups in basal CCK levels. However, the peak of CCK after the meal was significantly higher (P <0.01) in obese patients after VBG (24.9 ± 18 pmol/l) than before VBG (9.8 ± 6.7 pmol/l) and when compared with the control group (8.0 ± 6.3 pmol/l).The time needed to reach the peak was longer in healthy volunteers (105 ± 24.9 min) than in obese patients before VBG (45 ± 40 min) and after VBG (7.5± 12 min) (P<0.01). Conclusions: VBG increases the peak of CCK secretion and shortens the time to reach it. These changes could contribute to the satiety effects of gastric restrictive operations.     

Laparoscopic Mini-Gastric Bypass for Failed Vertical Banded Gastroplasty

Background: Bariatric surgery is the only method for sustained weight loss in morbid obesity. However, 10-25% of patients will require re-operation for unsatisfactory weight loss or weight regain after restrictive surgery. Re-operation is associated with higher morbidity and mortality. This study is to evaluate the s a fety and efficacy of laparoscopic mini-gastric bypass (LMGB) for failed vertical banded gastroplasty (VBG). Methods: From May 2001 to March 2003, 29 consecutive patients underwent LMGB for failed VBG. Average age was 39.7 years (range 22 to 56), and average BMI before re-operation was 41.7 kg/m² (range 35.0-70.8). 8 patients had previous open VBG, and 21 had laparoscopic VBG. The re-operation was for regain of weight in 16 patients, inadequate weight loss in 10 patients, and severe reflux esophagitis in 3 patients. Re-operation was performed after an average of 58.5 months (range 14 to 180). Results: All the re-operations were completed laparoscopically. Average operative time was 171.4 minutes (range 130 to 290). There was 1 mortality, due to leakage (3.4%). 1 re-operation was necessary, for incarceration of small bowel in a trocar wound 10 days after the LMGB (3.4%). 1 anastomotic site bleeding and 1 wound infection occurred. Average BMI 12 months after the LMGB was 32.1 kg/m² (range 26.4 to 42.7). The quality of life study was significantly improved. The revision operation had much more technical difficulty for those with previous open VBG than laparoscopic VBG. Conclusion: LMGB is an effective and safe revision operation for patients with failed VBG. A large series and long-term follow up is needed for confirmation.     

Carcinoma in the Gastric Pouch Years after Vertical Banded Gastroplasty

A 67-year-old lady presented with anemia and weight loss 15 years after vertical banded gastroplasty. The cancer was confined to the pouch, which is suggestive of a relationship to the anti-obesity surgery. A brief review with possible contributing factors is presented.     

Determinants of Long-Term Satisfaction after Vertical Banded Gastroplasty

Background: The long-term usefulness of vertical banded gastroplasty (VBG) in achieving weight loss is controversial, and adverse effects related to the procedure may attenuate patient satisfaction. Our objective was to evaluate patient satisfaction, and to identify parameters that are related to such satisfaction, 3 to10 years after VBG. Methods: All consecutive patients who underwent VBG in one surgical ward were invited for a follow-up study 3 to 10 years after surgery. Questions relating to symptoms and quality of life were evaluated in a personal interview using a structured questionnaire. Results: Of the 122 patients who underwent VBG from 1986 to 1992, 75 patients were located and agreed to participate in the follow-up study. The average time since surgery was 5.4 ± 1.8 years. The average weight loss was 24.9 ± 12.4%, representing an excess body-weight loss of 58.6 ± 30.4%. Overall, 65% of the patients were satisfied with the results of surgery while 19% expressed dissatisfaction. Significant improvement was seen in respiratory difficulties, ability to perform physical exercise, and mental status. Successful weight loss and the frequency of respiratory difficulties were the only independent parameters associated with patient satisfaction. Although vomiting, gastroesophageal reflux and difficulty in swallowing occurred in over two-thirds of the patients, their presence was not correlated with patient dissatisfaction. Conclusion: Despite the presence of a multitude of adverse effects, the majority of our patients were satisfied with the long-term results of VBG. Successful weight loss and improvement in respiratory difficulties were the major determinants of patient satisfaction.     

Successful Treatment of Gastric Fistula following Rhabdomyolysis after Vertical Banded Gastroplasty

Vertical banded gastroplasty is a gastric restrictive operation which has been performed with very satisfactory results in our department. We present a 46year-old male with BMI 48, who experienced rhabdomyolsis after a VBG operation, complicated by perforation of an upper pouch ulcer and subsequent gastric fistula. Cardiac and renal failure occurred, necessitating intensive therapy with catecholamines, diuretics and hemodialysis. The patient underwent multiple operations, drainage of a retroperitoneal abscess, suture of a perforated ulcer, and gastric decompression by a gastrostomy. Prolonged treatment including TPN, drainage, broad spectrum antibiotics, skin and would protection and jejunostomy feeding, were necessary to obtain an eventual successful outcome. This case demonstrates that unexpected surgical complications may occur in morbidly obese patients and how difficult and long the management of these may be. Rhabdomyolsis is a potentially life-threatening complication of bariatric surgery, and careful postoperative observation of the patient is mandatory.     

Conversion of Failed Vertical Banded Gastroplasty to Open Adjustable Gastric Banding

Background: Occasionally, patients with failed vertical banded gastroplasty (VBG) present for secondary treatment. We performed the reoperations using adjustable gastric banding (AGB) technique. Methods: From 1991 to 1997, 80 morbidly obese patients underwent VBG. In 7 (8.7%), staple-line disruption and weight regain were detected within 2 years of follow-up. Conversion to AGB was performed between 1994 and 1998. Meanwhile, another 80 morbidly obese patients underwent primary open AGB. Results: In the 7 patients, staple-line disruption was seen on radiography as a leak of contrast material across the gastric partition. After conversion of "failed" VBGs to AGB, postoperative results have been very satisfactory and similar to those of the primary open AGB group. Conclusions: VBG is a safe technique, although conversion rates were significant. Staple-line disruption constituted the chief cause of insufficient weight loss and frequently indicated the need for further surgery. Our results of the revisional surgery confirm that the reoperations for failed VBG can be performed using AGB technique.     

Comparative Analysis of Vertical Banded Gastroplasty and Duodenal Switch at Five Years Follow-Up

Background: Bariatric surgery is the only effective long-term treatment for morbid obesity. We compared long-term results of the vertical banded gastroplasty (VBG) and biliopancreatic diversion with duodenal switch (DS). Quality of life (QoL), weight loss (WL), and reoperation were evaluated. Methods: This is a retrospective study of 85 of 129 patients with VBG and 49 of 743 patients with DS, with follow-up >5 years. Mean preoperative BMI of the VBG patients was 48.8 kg/m² and for the DS patients was 50.3 kg/m². Results: Percent excess weight loss (%EWL) at 5 years for VBG patients was 56.4% and for DS patients 70.6% (P<0.0001). 8 VBG patients (9.4%) and 1 DS patient (2.0%) required re-operation due to failure of the technique. None of the VBG patients could eat a normal diet, while 80% of the DS had no restriction in the quality of their intake. Conclusions: At 60 months follow-up, only the DS patients fullfilled the ASBS requirements of %EWL >50 in over 75% of the patients.     

Laparoscopic Vertical Banded Gastroplasty: Early Results with the JOVO Procedure

Background: Vertical banded gastroplasty (VBG) is an established treatment for morbid obesity for selected patients. This study seeks to assess the effectiveness of a laparoscopic version, the JOVO procedure, of the VBG. Methods: An independent surgeon interviewed all patients, who had had the JOVO procedure at one institution, evaluating weight loss, comorbid conditions, satisfaction and quality of life using the 36-item short-form health survey (SF-36). Results: 14 JOVO procedures were done by two surgeons. Mean body mass index was 44 kg/m², mean age 30 years and each patient had at least one comorbid condition. Mean operative time was 165 minutes. There was 1 complication, a suspected gastric leak requiring reoperation. Excluding this patient, mean hospital stay was less than 48 hours. Mean weight loss 4 weeks after surgery was 9 kg or 18% of excess weight. Mean excess weight loss of the 5 patients available for 1-year follow-up was 42% at 6 and 85% at 12 months; 1 did not continue to lose weight. All but 1 preoperative comorbid condition resolved or improved. 13 of the 14 patients were fully satisfied. SF-36 scores were high in the 13 that lost weight, especially in physical and social functioning areas. Conclusion: The JOVO procedure is safe and reproduces laparoscopically the early weight loss of open VBG with much shorter hospital stay and low complication and failure rates. Longer follow-up and larger numbers are needed.     

Vertical Banded Gastroplasty: 6 Years Experience at a Center in Poland

Background: Vertical banded gastroplasty (VBG) has been performed in our department as a restrictive operation for treatment of morbid obesity. We assessed efficacy, safety, and quality of life (QoL) after VBG, based on our 6-year experience. Methods: 101 patients with >1 year follow-up who underwent VBG between January 1998 and May 2003, were retrospectively studied. Mean age was 41 years, and mean preoperative BMI was 51.3 kg/m² . Almost 60% of the patients suffered from hypertension, and 25% were diabetic. Postoperative QoL was determined with the BAROS questionnaire. Data concerning weight loss and co-morbidities were collected during the postoperative visits. Results: 87.2% of patients achieved ≥ 50% EWL. 86 patients (85.2%) responded to the BAROS questionnaire. >90% of the patients analyzed according to BAROS, reported improvement in QoL after VBG. No patient reported deterioration in health or well-being after the VBG. Anti-hypertensive medication was discontinued in 26 patients (56.5%) and decreased in the other 15 hypertensive patients (32.6%). 35% of diabetic patients did not require further treatment, while a further 40% had their insulin doses decreased or were switched to oral drugs. Early complications occurred in 4.65%, and consisted of an evisceration, pulmonary embolus and gastric leak. Late complications occurred in 20.9%, and included bleeding from peptic ulcer, incisional hernia, stomal stenosis and staple-line disruption (3.5%). There have been no deaths. Conclusion: VBG provided significant weight reduction and improved QoL in the vast majority of morbidly obese patients. Patients with diabetes and hypertension benefitted because these co-morbidities were improved or disappeared with the weight loss.     

Revision of Failed Vertical Banded Gastroplasty to Non-resectional Scopinaro Biliopancreatic Diversion: Early Experience

Background: The most commonly performed revision operation following failed vertical banded gastroplasty (VBG) is Roux-en-Y gastric bypass, although revision to biliopancreatic diversion (BPD) with duodenal switch is now another common option. We describe the surgical technique for revision of a failed VBG to a non-resectional Scopinaro BPD in a series of patients, as well as the outcome in terms of complications and mean % excess weight loss (%EWL). Methods: A retrospective review was conducted on all patients who underwent revision to BPD at Mercy Bariatrics, Western Australia, between June 2001 and April 2005. This yielded 20 patients who had revision to BPD, 9 of whom had VBG as their initial operation. The mean %EWL was measured at regular intervals postoperatively (3, 6, 12, and 24 months). Results: Mean %EWL at 12 and 24 months was 69.5 and 76.7, respectively. These results are comparable to %EWL after a primary BPD. Nutritional manifestations were found to be the most common of the minor complications. Conclusion: Our technique for revision of a failed restrictive operation to a non-resectional Scopinaro BPD is described. The preliminary results in terms of %EWL and complications are comparable to other revisional malabsorptive operations. Prospective randomized controlled trials are needed to further evaluate effects of revision to a non-resectional Scopinaro BPD and to ensure that the results (in terms of %EWL) are reproducible.     

Preoperative Resting Energy Expenditure Does Not Predict Weight Loss and Maintenance after Vertical Banded Gastroplasty

Background: The authors evaluated the predictive efficacy of preoperative resting energy expenditure (REE) on long-term weight loss maintenance following vertical banded gastroplasty (VBG). In the long-term following VBG, low energy expenditure could lead to regain of weight, and thereby REE data might be a reliable predictor of long-term weight outcomes. Methods: A prospective study was conducted, taking into account the relationship between preoperative REE values and the results at 3 and 5 years following VBG in terms of both weight loss and success of the operation. Results: Long-term weight loss and outcome following VBG appeared to be completely independent of the preoperative REE. Conclusion: Preoperative REE cannot predict long-term weight outcome following VBG.     

Serum Hepatocyte Growth Factor Concentration in Obese Women Decreases after Vertical Banded Gastroplasty

Background: Human obesity is associated with increased serum hepatocyte growth factor (HGF) concentration. This study examines whether reduced body fat mass after vertical banded gastroplasty (VBG) is associated with a decrease in serum HGF concentration. Methods: Serum HGF concentration and body weight, BMI, body fat mass, blood pressure, serum leptin, insulin, triacylglycerol, and cholesterol concentrations were studied in 10 obese women before and 1 year after VBG. 10 lean, healthy women were used as controls. Results: Obese women showed significantly higher serum HGF concentration than control (lean, healthy) subjects. The mean serum HGF concentration decreased significantly 1 year after VBG, but did not reach the value observed in lean women. After VBG, BMI, body fat mass and serum HGF had similar patterns of decrease. Moreover, serum HGF concentration was positively correlated with both BMI (r=0.6, P<0.01) and body fat mass (r=0.6, P<0.01). Before surgery in obese women, elevated blood pressure was observed, which decreased after VBG. Linear regression analysis between blood pressure and serum HGF concentration using all subjects, showed no correlation between either systolic blood pressure and serum HGF concentration (r=.15, P=NS) or between diastolic blood pressure and serum HGF concentration (r=0.1, P=NS). Insulin resistance index (HOMA score), serum leptin, insulin and triacylglycerol concentrations decreased 1 year after VBG. However, serum cholesterol concentration did not change significantly. Conclusions: These results indicate that VBG results in a reduction in circulating HGF concentration. The reduced body fat mass may contribute in part to the decrease of serum HGF concentration after VBG. Because elevated serum HGF concentration may contribute to the progression of atherosclerosis, the decrease in serum HGF concentration after VBG may be beneficial for obese subjects.
