Vertical banded gastroplasty

VBG and vertical Silastic ring gastroplasty are simple gastric restriction procedures that have defined technical standards. Two recent improvements in the operation have been the development of the six-row endolinear cutting-stapling instrument that divides the vertical partition without an increase in GI leakage and the application of minimally invasive laparoscopic techniques that have reduced the incidence of incisional hernia to less than 1%. VBG and vertical Silastic ring gastroplasty are procedures that can effectively help select patients to manage their morbid obesity. However, these procedures are critically dependent on patient compliance. It is not possible to know preoperatively whether a candidate will make the lifelong behavior modifications necessary for sustained weight loss. Experience has demonstrated that bariatric surgeons have limited control over a patient's level of motivation for compliance.     

Vertical banded gastroplasty: assessment of efficacy

We previously demonstrated unacceptably high failure rates with horizontal gastroplasty. Shortly thereafter, vertical banded gastroplasty was introduced. Since April 1982 we have operated on 56 patients who were carefully selected and closely followed. There were 10 men and 46 women, aged 15 to 54 years (mean age 36 years) with preoperative weights of 93.5 to 198.6 kg (mean 125.9 kg). The mean weight loss at 6 to 12 months was 36 +/- 10 kg, or 30% of body weight. At 18 months, data were available for 48 of the 56 patients. Their weight losses were 44 +/- 11 kg, or 35% of body weight. Eight patients were lost to follow-up. The weight of nine additional patients plateaued before they lost 30% of their starting weights and another eight patients have started to regain weight after achieving satisfactory weight loss. Included are two patients with severe stenoses who regained all weight lost.     

Vertical banded gastroplasty: operation for morbid obesity

Modern stapling equipment makes it possible to perform the vertical banded gastroplasty without major technical difficulties. Follow-up to date confirms its efficacy as a weight reducing procedure in the morbidly obese.     

Vertical banded gastroplasty as an antireflux procedure

Vertical banded gastroplasty creates a channel by two applications of the TA-90 stapler from an end-to-end anastomosis window above the crow's foot to the angle of His, against a 32 F. tube along the lesser curvature. The caudad end of the channel is restricted by a 5 cm collar. Thirty-one obese patients more than 45 kg overweight were studied by interview, barium swallow, endoscopy, and manometry. These procedures were repeated 13 +/- 5.5 weeks postoperatively, after resolution of operative edema and before extensive weight loss. Preoperative symptoms included heartburn in 24 patients, regurgitation in 17 patients, and aspiration in 2 patients, and barium swallow demonstrated hiatal hernia in 7 patients and reflux in 7 patients (5 with hiatal hernia). In addition, endoscopy detected mild esophagitis in 3 patients, and hiatal hernia in 11 patients. Postoperatively, the incidence of heartburn decreased in all patients, barium swallow showed slow channel emptying but no hiatal hernia or reflux, and endoscopy did not identify any esophagitis. Preoperative lower esophageal sphincter pressure was 14.5 +/- 7.2 mm Hg. Postoperatively, the vertical banded gastroplasty channel had an initial peak (collar) pressure of 19.2 +/- 7.8 mm Hg (p less than 0.01 compared with preoperative lower esophageal sphincter pressure), a channel pressure of 9.5 +/- 6 mm Hg, a lower esophageal sphincter pressure of 20.1 +/- 7.7 mm Hg (p less than 0.005), and a channel length of 6.8 +/- 1.4 cm. Vertical banded gastroplasty creates a high pressure channel, inhibiting reflux of gastric juice without the need for any additional procedure.     

Vertical banded gastroplasty in the Aegean Region of Turkey

Background: Obesity is increasing in Turkey. The first experience with vertical banded gastroplasty (VBG) with regular intermediate-term follow-up in the Aegean Region of Turkey is presented. Methods: From November 1993 to August 1999, 40 morbidly obese patients underwent VBG. The patients were evaluated on the basis of excess weight loss (EWL) and satisfaction with the operation. Results: Regular follow-up was obtained in 38 patients (95%), with mean follow-up 27.2 months (14-85). Average preoperative body weight (BW) was 141.4 kg (93-238) and body mass index (BMI) was 52.3 kg/m² (41-77.8). Average EWL was 64.1% (21.2-92.3). Average postoperative BW and BMI were 93.3 kg (70-145) and 34.4 kg/m² (25.1-53) respectively. 35 of 38 patients (92%) lost more than 25% of EW and 28 of 38 (73.6%) lost more than 50% of EW. After weight loss, hypertension disappeared or improved in 86% of patients and diabetes resolved in 75%. Sleep apnea disappeared in 100% of patients. The early and late complication rates were 7.9% and 15.8% respectively. 33 of 38 patients (87%) were satisfied with the operation. Conclusion: VBG was safe and effective, resulted in acceptable weight loss, and the vast majority of patients were satisfied.     

Vertical banded gastroplasty versus adjustable gastric banding: prospective long-term follow-up study.

BACKGROUND: Vertical banded gastroplasty (VBG) has been in clinical use since 1979 and adjustable gastric banding (AGB) since 1985. Because promising results were achieved with the adjustable gastric bands available in the market, some surgeons came to the conclusion that VBG might be entirely abandoned and replaced by the adjustable gastric band. The aim of this study was to compare the long-term outcome of the 2 restrictive procedures. METHODS: Within a 7-year period (1994-2001), 1117 gastric restrictive procedures were performed in the course of a prospective nonrandomized comparative trial. We report the outcomes of 563 VBG and 554 AGB procedures performed by 2 surgeons. The mean body mass index was 46.9 +/- 09.9 kg/m(2) for VBG and 46.7 +/- 07.8 kg/m(2) for AGB. Patient selection was performed by acceptance by 1 of the 2 surgeons. VBG was performed by laparotomy and AGB using laparoscopy. The Bariatric Analysis and Reporting Outcome System (BAROS) was used to evaluate the postoperative health status and quality of life. RESULTS: The mean duration of follow-up was 92 months (range 60-134), with a minimum of 5 years. The overall follow-up rate was 92%. In the short-term 3-year follow-up, no statistically significant difference was registered between AGB and VBG in terms of weight loss, reduction of co-morbidities, or improvement in quality of life. The 30-day mortality rate was .4% (2 patients) for VBG and .2% (1 patient) for AGB. The overall reintervention rate in the long term was 49.7% for VBG and 8.6% for AGB (P <.0001, odds ratio .0937, 95% confidence interval .065-.133), the reoperation rate was 39.9% for VBG and 7.5% for AGB (P <.0001). The excess weight loss was significantly greater in the VBG group after 12 months (58% for VBG versus 42% for AGB, P <.05). At long-term follow-up (mean 92 months), no significant difference in weight loss was registered between the 2 study groups (59% for VBG and 62% for AGB, P = .923). The BAROS score in the short term (3 years) was good to excellent in 94% and 90% of the VBG and AGB groups, respectively. In the long-term follow-up period, the BAROS score was significantly in favor of the AGB group (83.9% versus 57.8%, P <.0001, odds ratio 3.797, 95% confidence interval 2.072-7.125). The overall resolution rate of co-morbidities was 80% in both groups. CONCLUSION: This long-term follow-up study shows that VBG and AGB are effective restrictive procedures to achieve weight loss, and loss of co-morbidities. A statistically significant lower re-intervention and re-operation rate and an improved health status and quality of life were registered for AGB.     

Laparoscopic vertical banded gastroplasty

Background The commonest surgical procedure for management of morbid obesity in Europe is laparoscopic adjustable gastric banding (LAGB), even though laparoscopic vertical banded gastroplasty (LVBG) is still considered to be a gold standard restrictive option in bariatric surgery. A multicenter prospective study was designed to to assess the efficacy of LVBG in terms of weight loss and complication rates for obese patients who have indications for a restrictive procedure. Patients and methods Two-hundred morbidly obese patients (84.5% female) with a mean age of 41 years and mean body mass index (BMI) of 43.2 kg/m² underwent LVBG as described by MacLean. Five trocars were placed in standard positions as per laparoscopic upper gastrointestinal surgery. A vertical gastric pouch (30 ml) was created with circular (21 or 25mm) and endolinear stapling techniques, enabling definitive separation of the two parts of the stomach. The gastric outlet was calibrated with either a polypropylene mesh (5.5 cm in length and 1cm in width) or a nonadjustable silicone band. The median follow-up period was 30 months (range, 1–72 months). Results One case had to be converted to open surgery (gastric perforation) and there was one death secondary to peritonitis of unknown etiology. The morbidity rate was 24%, comprising the following complications: gastric outlet stenosis (8%); staple line leak (2.5%); food trapping (1.5%); peritonitis (1%); thrombophlebitis (1.5%); pulmonary embolism (0.5%); and gastroesophageal reflux (9%). The excess weight loss achieved was 56.7% (1 year), 68.3% (2 years), and 65.1% (3 years). Conclusions Laparoscopic vertical banded gastroplasty is an effective procedure for the surgical management of morbid obesity, especially for patients who present hyperphagia but are unable to manage the constraints of adjustable gastric banding. Laparoscopic vertical banded gastroplasty is safe, as demonstrated by an acceptable complication rate, of which gastric outlet stenosis, staple line leakage, and gastroesophageal reflux predominate.     

Long-term results after revisions of failed primary vertical banded gastroplasty

AIM: To compare the results after revision of primary vertical banded gastroplasty(Re-VBG) and conversion to sleeve gastrectomy(cS G) or gastric bypass(cR YGB).METHODS: In this retrospective single-center study, all patients with a failed VBG who underwent revisional surgery were included. Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent c SG and 115 patients underwent c RYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss(%EWL) after Re-VBG, cS G and cR YGB was, respectively, 45%, 57% and 72%. Eighteen patients(11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Rouxen-Y gastric bypass seems feasible as a revision for a failed VBG.     

Obesity surgery: discouraging long term results with Mason's vertical banded gastroplasty.

OBJECTIVE: To evaluate the long term results of Mason's vertical banded gastroplasty (VBG) using accepted criteria, and to find out which factors predicted success. DESIGN: Retrospective survey of a cohort of 40 severely obese patients (mean initial body mass index (BMI in kg/m2): 43, range 34-62). SETTING: General teaching hospital, The Netherlands. MAIN OUTCOME MEASURES: Success according to three definitions: weight loss of more than 25%; percentage of excess weight 50% or less; and BMI < 30. RESULTS: Mean follow-up was 7.4 years (range 0.5-10) or 85%. The distribution over MacLean and Reinhold criteria shows a shift towards unfavourable categories. The consecutive percentages of success at five years were 35%, 62%, and 35%. Logistic regression analysis of success at 5 years shows that the following factors significantly predicted success: Definition I: age odds ratio (95% confidence interval): 0.88 (0.78 to 0.99). Definition II: age: 0.84 (0.69-1.01), outlet > or = 5 cm: 176 (2.4 to 12774), percentage of ideal weight > or = 100%: 0.03 (0.002 to 0.48). Definition III: age: 0.86 (0.75 to 0.99), pouch size > or = 15 ml: 10.64 (1.48 to 76.6). CONCLUSION: The long term results of VBG are disappointing when assessed by the standard criteria.     

Late results of vertical banded gastroplasty for morbid and super obesity

Two hundred one patients who underwent vertical banded gastroplasty have been followed up for a minimum of 2 years to more than 5 years. Staple line perforations occurred in 48% of patients, and 36% underwent reoperation. The instability of the operation becomes apparent only with careful follow-up. More than 50% of patients who maintained a small orifice of less than or equal to 11 mm in diameter and an intact staple line over 3 to 5 years achieved an excellent result (0% to 25% excess weight), which equals the best results in the literature for any gastric-limiting operation, whether bypass or gastroplasty. The results of this operation for super obesity (a body mass index greater than or equal to 50 kg/m2) are disappointing. Only 8% of these patients achieve an excellent result. Failure of vertical banded gastroplasty in the morbidly obese (body mass index of 40 to 50 kg/m2) is frequently technical, and a method that eliminates dependence on integrity of staples should be evaluated. Results should be reported so that unsatisfactory results are apparent. Mean weight loss and mean percent excess weight loss are both highly satisfactory in this study, whereas unsatisfactory results ranged from 10% to 21% for each of the 5 years of follow-up.     

Hand-assisted laparoscopic vertical banded gastroplasty

BACKGROUND: Minimally invasive hand-port-assisted laparoscopic vertical banded gastroplasty has the potential to reduce postoperative complications after bariatric surgery. METHODS: We analyzed the postoperative course of 46 hand-port-assisted laparoscopic vertical banded gastroplasties (LVBG) completed between January 1998 and April 1999. RESULTS: The operating time for the LVBG was shorter (140.8 +/- 6.0 vs 180.2 +/- 6.3 min; p < 0.05). Individuals were able to ambulate sooner (1.36 +/- 0.09 vs 2.44 +/- 0.16 days; p < 0.05), and start oral intake earlier (2.7 +/- 0.27 vs 3.7 +/- 0.17 days; p < 0.05) than the open vertical banded gastroplasty (VBG) controls. Three staple line leaks were detected in this group. Two leaks resolved without clinical sequelae, but one patient developed intraabdominal sepsis. This complication extended the average hospital stay to 6.8 +/- 2.00 days, as compared to 7.71 +/- 0.18 days for historical controls. By discounting this patient from the analysis, we arrive at a more representative length of hospitalization of 4.82 +/- 0.34 days (p < 0.05). CONCLUSIONS: LVBG offers a good alternative to the standard open VBG. Although this procedure has a relatively short learning curve, it should be done at centers with an interest in bariatric surgery.     

Endoscopy of vertical banded gastroplasty

Vertical banded gastroplasty is the most common operation for morbid obesity. Postoperative gastroscopy was needed 91 times in 79 of 696 patients for 1) abdominal pain (23), 2) excess vomiting (22), 3) inadequate weight loss (14), 4) excess weight loss (13), 5) and a sudden increase in eating capacity (7). A normal appearance consisted of a clean gastric channel 6.8 +/- 1.4 SD cm long, with a rosette 46.6 +/- 2.1 cm from the incisors and, with insufflation, an 11 mm scope passed through this pseudopylorus snugly, but without difficulty. In Group 1, no problem was seen in the channel, and cholecystitis was found to be the cause. In Group 2, no problem was observed in ten (poor teeth and chewing), six experienced stasis or pill ulcerations, four had bezoars (fragmented or removed with basket), and two had intraluminal mesh. In Group 3, the scope floated through too large an outlet (greater than or equal to 13 mm) in eight, and no cause was seen in six (gorgers, sweets-eaters). In Group 4, tightness or stricture resolved with dilatations (Eder-Puestow; Savary; balloon dilators) in six, but seven required re-operation. In Group 5, the scope travelled through four breakdowns in the partition and three outlets were too large. Gastroscopy viewed problems accurately, indicated treatment and suggested modifications in gastroplasty technique.
