Distal Esophageal Erosion After Laparoscopic Adjustable Gastric Band Placement with Nissen Fundoplication Takedown

Although primary band placement is proven to be safe, gastric band placement after previous operations in the area of the gastroesophageal junction remains controversial. Erosion into the stomach has been described after failed vertical banded gastroplasty conversion to laparoscopic gastric banding (LAGB), but no reports in the English literature are available on erosion of an adjustable gastric band into the esophagus after conversion operations. To our knowledge, this is the first case report of distal esophageal erosion after LAGB placement with Nissen fundoplication takedown.     

Barrett’s Esophagus: A Late Complication of Laparoscopic Adjustable Gastric Banding

Laparoscopic adjustable gastric banding has become a popular bariatric restrictive procedure in the USA. The increasing popularity of the laparoscopic adjustable gastric band procedure could, in part, be related to the lower cost and lower morbidity compared with laparoscopic gastric bypass. Although its placement is related to a lower number of perioperative complications compared with laparoscopic gastric bypass, its morbidity may be substantial. Barrett’s esophagus or esophageal intestinal metaplasia is a known complication of chronic gastro-esophageal reflux disease that, in rare occasions, progresses to dysplasia and esophageal adenocarcinoma. Barrett’s esophagus, after laparoscopic adjustable gastric banding placement, is a rare but not unexpected complication after gastric band placement. The incidence of Barrett’s esophagus after adjustable gastric banding is not known. We present a case of Barrett’s esophagus as a result of laparoscopic adjustable gastric banding placement due to a chronically and highly restrictive gastric band in a former morbidly obese patient.     

Biliary-Venous Fistula Complicating Transjugular Intrahepatic Portosystemic Shunt Presenting With Recurrent Bacteremia, Jaundice, Anemia and Fever

A 50-year-old White man with noncirrhotic portal hypertension presented with bleeding from gastric varices. Bleeding was initially managed with band ligation and subsequent transjugular intrahepatic portosystemic shunt (TIPS). Over the next few months, the patient had recurrent episodes of anemia, jaundice, fever and polymicrobial bacteremia. Computed tomography (CT) of the abdomen and chest, upper and lower endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), and echocardiography failed to explain the bacteremia and anemia. Follow-up CT scan and Doppler sonography 9 months after placement showed TIPS was occluded. Repeat ERCP showed a bile leak with free run-off of contrast from the left hepatic duct into a vascular structure. The patient's status was upgraded for liver transplantation with Regional Review Board agreement and subsequently received a liver transplant. Gross examination of the native liver demonstrated a fistula between the left bile duct and the middle hepatic vein. Pathologic evaluation confirmed focal necrosis of the left hepatic duct communicating with an occluded TIPS and nodular regenerative hyperplasia consistent with noncirrhotic portal hypertension. Infection is rarely reported in a totally occluded TIPS. Biliary fistulas in patent TIPS have been treated by endoluminal stent graft and endoscopic sphincterotomy with biliary stent placement. Liver transplantation may be the preferred treatment if TIPS becomes infected following its complete occlusion.     

Laparoscopic adjustable gastric banding: surgical technique

Laparoscopic adjustable gastric banding is an effective and safe surgical treatment for morbid obesity. Initial experience with the Lap-Band system (Inamed Health, Santa Barbara, California) in the United States and Australia has demonstrated that surgical technique can affect outcomes in terms of weight loss, quality of life, and complication rates. Placement of the gastric band by means of the perigastric technique is associated with high rates of gastric prolapse, food intolerance, and weight loss failure that frequently lead to band explantation. In the pars flaccida technique, band placement higher on the stomach results in the formation of a smaller pouch and lower rates of gastric prolapse, which may contribute to greater weight loss and improved quality of life. This article describes the technical aspects of the pars flaccida approach in the laparoscopic placement of adjustable gastric bands.     

Intermittent Obstructive Jaundice following Gastric Band Placement

Complications of laparoscopic adjustable gastric banding occur in 10–20% of patients. However, hepatobiliary complications of this procedure are very rare. We report a unique case of gastric band misplacement around the hepato-duodenal ligament. The patient developed obstructive jaundice several months after the gastric band placement and suffered recurrent episodes of obstructive jaundice and cholangitis that were initially erroneously attributed to fatty infiltration of the liver. Further diagnostic work-up demonstrated the presence of the gastric band in the hepatic hilum. Exploratory laparotomy confirmed the diagnosis, and the band was removed. Jaundice reversed and hepatic function was restored following removal of the occluding band.     

Epiphrenic Esophageal Diverticulum after Laparoscopic Placement of an Adjustable Gastric Band

A morbidly obese woman (BMI 56 kg/m²) in 1998 underwent laparoscopic placement of an adjustable gastric band by the perigastric approach. 5 years later, she complained of reflux and weight regain. X-ray with contrast revealed pouch dilatation. She subsequently underwent a laparoscopic revision including retrocardia band replacement using the pars flaccida technique. During the further course, an epiphrenic diverticulum was diagnosed. Because of danger of perforation of the large thin-walled diverticulum and the esophagel motility disorder, the band was laparoscopically removed and the diverticulum was resected via a transhiatal approach. This case presents a very rare complication after placement of a gastric band and its successful management.     

Caution in using a unique technique of banded revision gastric bypass: Successful endosopic and surgical management of a rare complication

INTRODUCTIONRevision surgery is increasingly performed as result of the increase in primary bariatric procedures. We describe a new technique of revision Roux-en-Y gastric bypass (RYGB) acombining stapled gastroenterostomy with fixed band placement. We report two cases of unique complications and its successful endoscopic and surgical management.PRESENTATION OF CASETwo out of twenty patients undergoing this revision RYGB procedure presented with gastric outlet obstruction due to band erosion within 10 weeks. Endoscopic band retrieval was successful in the first patient but the second patient required surgical removal.DISCUSSIONWe report the new complication of band erosion in 10% patients using a unique revision RYGB technique combining restriction of the gastric outlet and band placement. We advise using one or the other technique but not both in combination. Surgeons need to be aware of this as erosion which occurs early due to close proximity of band with fresh staple line. We report successful endoscopic and surgical management.CONCLUSIONRevision surgery using this technique predisposes to bande erosion, presenting as gastric outlet obstruction. Endoscopic management should be attempted prior to surgical removal.     

Technical Points in Vertical Gastroplasty for Morbid Obesity

The success of vertical gastroplasty may be jeopardized by gastric leakage or ulceration due to failure of the technique. Reports of band erosion and staple-line leakage have led us to seek technical improvements to reduce technical failures. We describe a modification to the technique of band placement and a manoeuvre to aid the placement of staples when the TA90 staple gun is used.     

11-cm Lap-Band<Superscript>®</Superscript> System Placement after History of Intragastric Migration

Background: Intragastric migration (erosion) of the band after laparoscopic adjustable silicone gastric banding (LAGB) is a serious late complication. It requires removal of the entire system. Subsequent recurrence of obesity can be treated by laparoscopic placement of a larger band: the 11-cm Lap-Band^? System. Methods: In 727 laparoscopic gastric bandings using the 9.75 Lap-Band^?, 10 cases presented with intragastric migration of the band. The same complication was encountered in an additional 4 patients who had previously been implanted with an Obtech band in another hospital. Laparoscopic removal of the band was performed in all cases. In 9 cases, after a delay of 6 months, a new gastric band was placed using the 11-cm Lap-Band^?, because of uncontrollable recurrence of obesity. Results: No complication was observed during the laparoscopic removal of the system. The placement of a new band required conversion to laparotomy in 1 patient who had previously received an Obtech band which had been placed using the pars flaccida technique. After a mean follow-up of 21 months, no intragastric migration of the new bands was noted. Conclusions: Laparoscopic placement of an 11-cm Lap-Band^? in patients with a history of intragastric migration is a safe procedure. It allows effective control of recurrent obesity. The laparoscopic procedure was easier in patients initially operated using the perigastric technique.     

Lassoing of the small bowel mesentery and abdominal pain caused by band tubing after “band on bypass”

Weight regain after laparoscopic gastric bypass can be difficult to manage. A common finding is an enlarged gastrojejunal complex (dilated gastric pouch and/or jejunum, dilated gastrojejunal anastomosis). Revision of the gastrojejunal complex can be accomplished by surgical resection [1], endoscopic plication techniques [2], or more recently, placement of an adjustable band around the dilated gastric pouch (“band on bypass,” BoB). We present an unusual complication of the BoB procedure, in which the band tubing looped around the small bowel causing severe abdominal pain.     

Effect of Laparoscopic Gastric Banding on Esophageal Motility

Background: Alterations in esophageal motility may occur after placement of an adjustable gastric band as treatment for morbid obesity, near the gastro-esophageal junction. It causes an outlet obstruction, especially during follow-up after the band is filled. Methods: 29 morbidly obese patients underwent conventional manometry preoperatively, 6 weeks postoperatively before and after filling the band and at 6 months postoperatively. A questionnaire was used to assess upper gastrointestinal symptoms during follow-up. Results: After band placement, there was a significant increase in lower esophageal sphincter (LES) end-expiratory pressure at 6 weeks with an empty band: 1.3 (0.9-1.9) kPa (median (interquartile range) (P=0.003), 6 weeks with a filled band: 2.1 (1.5-2.8) kPa (P=0.0001), and at 6 months: 1.5 (1.3-1.9) kPa (P=0.001), compared to the preoperative pressure: 0.8 (0.6-1.3) kPa. Also after band placement, the high pressure zone length increased (preop 5.0 (4.3-6.0) cm vs 6 weeks 6.0 (5.0-6.5) cm (P=0.003). The propagation of peristaltic contractions was not significantly altered after band placement. Heartburn decreased 6 weeks postoperatively (P=0.04) but increased at 6 months. Heartburn at 6 months was correlated with pouch formation (0.667; P<0.01). Conclusion: Adjustable gastric band placement causes an increase in LES pressure and length of the high pressure zone. It decreases reflux symptoms in the short-term, but this effect appears not to be related to an effect on LES pressure or length. Pouch formation increases reflux symptoms without having any relationship to LES pressure and length. Band placement in the short-term does not disturb propagation of esophageal contractions.     

Is Esophageal Dysmotility after Laparoscopic Adjustable Gastric Banding Reversible?

Laparoscopic adjustable gastric banding (LAGB) has become an increasingly popular option to treat morbid obesity. Esophageal dysmotility secondary to LAGB has been described, but is usually reversible after removal of the band. Long-term esophageal dysmotility persisting after removal of the band is an unusual and not yet described complication. We report the case of a 58-year-old obese patient who developed severe dysphagia and vomiting associated with atypical esophageal dysmotility 22 months after gastric band placement. Radiological exploration revealed no acute band slippage but only a pseudoachalasia. Device deflation and then band removal were required in an attempt to treat her symptoms. Esophageal dysmotility persisted for several months after band removal and was still present after a Rouxen-Y gastric bypass performed as revisional operation. Possible mechanisms generating this complication and clinical implications are discussed.     

A New Surgical Technique for the Silicone Gastric Band in the Presence of a Large Hiatus Hernia

Background: The purpose of this study was to establish the efficacy of a new surgical technique for the placement of the silicone gastric band (LAP-Band) in the presence of a large (>5 cm) hiatus hernia. Method: Hiatus hernias >5 cm were identified by endoscopy and barium meal in 6 patients. Each patient underwent hiatal hernia repair and attempted gastrodesis with laparoscopic placement of a gastric band. Results: At 6 months, there were no complications. Mean weight loss was 16 kg. Conclusion: Repair of hiatus hernia with hiatal repair and gastrodesis of the posterior aspect of the stomach may allow some patients to undergo a procedure previously considered contraindicated.     

Translumenal Endoscopic Drainage of Abdominal Abscess Due to Early Migration of Adjustable Gastric Band

We describe the case of early band migration that developed into intraabdominal infection treated by natural orifice translumenal endoscopic surgery. A 40-year-old man was seen 4 years after gastric band placement. He complained of epigastric pain and fever. Gastroscopy revealed minimal gastric fundus erosion and a bulging of the antrum wall. Abdominal CT scan showed perigastric abscess surrounding the band tube. Antibiotic therapy was initiated, and endoscopic transgastric abscess drainage was performed. The endoscope was guided into the abscess cavity, and the band tubing was brought into the gastric lumen to serve as a stent to drain the infection, which ceased 5 days later. During the follow-up, the mucosa covering the band was incised in two more sessions to hasten the erosion process. Endoscopic removal was done 7 months after the drainage.     

Band erosion: laparoscopic removal of lap-band

Laparoscopic gastric banding is in the category of purely restrictive gastric procedures. It offers the advantage of being minimally invasive, adjustable, and reversible. The incidence of band erosion with penetration into stomach is well documented in literature. We present a case of band erosion and simultaneous laparoscopic removal of lap-band through the same incisions used for its placement. The stomach was repaired with laparoscopic suture placement and an omental patch was placed on top of the repair along with fibrin glue and a JP drain. An upper gastrointestinal study demonstrated no extravasation of contrast and the patient was discharged postoperative day 1.

Improvement of esophageal dysmotility after conversion from gastric banding to gastric bypass

BackgroundPatients undergoing adjustable gastric banding can develop clinically apparent alterations in esophageal motility. There is little data on how such patients do after band removal and revision to other bariatric operations. One article in the literature describes long term manometric evidence of dysmotility in a band patient converted to gastric bypass.Methods132 patients undergoing placement of an adjustable gastric band by a single surgeon in a university hospital setting were followed over a two year period. 15 (11%) developed unrelenting dysphagia, reflux and regurgitation despite conservative management including complete deflation, and were revised to gastric bypass. Pre-revision contrast studies demonstrated esophageal dysmotility in all patients. The first seven were converted in a staged fashion, with a period of six to eight weeks between band removal and gastric bypass. During this time, motility was again studied to confirm a return to normal. The last eight were converted at the time of band removal and motility was restudied after gastric bypass.ResultsEsophageal motility normalized radiologically after band removal and remained normal after conversion to bypass in all patients. Symptoms of dysphagia similarly resolved. The revisional complication rate was acceptable.ConclusionThe presence of a gastric band may be sufficient in some patients to bring about esophageal dysmotility. However, many will bring this about through forced eating against the band. When the band is poorly tolerated and further weight loss is required, such patients can safely convert to gastric bypass and can expect a return to normal motility.     

Laparoscopic single-site surgery for placement of adjustable gastric band—a series of 22 cases

BackgroundWe present a series of 22 patients who underwent laparoendoscopic single-site (LESS) surgery for placement of an adjustable gastric band at a U.S. university hospital.MethodsFrom December 2007 to December 2008, LESS surgery, through a transumbilical incision, to place an adjustable gastric band was performed on 22 patients under institutional review board approval. Multiple ports were placed through a single incision in the umbilicus to allow for liver retraction, visualization, and the working instruments. None of the critical steps of the standard pars flaccida technique were altered.ResultsA total of 22 patients were carefully selected and included 20 women and 2 men, with an age range of 18–67 years (mean 42). The mean body mass index was 42 kg/m² (range 35–45). The exclusion criteria included hepatomegaly, central obesity, previous abdominal surgery, and super-obesity. The mean operative time was 84 minutes (range 53–111). All patients were discharged home within the 23-hour admission, and no perioperative complications were noted. In addition, no wound-related complications developed. One patient required conversion to conventional laparoscopy. No intraoperative or postoperative complications occurred.ConclusionIn our experience, LESS surgery for adjustable gastric band placement shows this technique to be both feasible and safe in selected patients to date. Although technical limitations exist that will be improved on, additional studies are needed to compare LESS surgery for placement of an adjustable gastric band with traditional laparoscopic techniques.     

Gastric Necrosis: a Rare Complication of Gastric Banding

In the last decade, laparoscopic gastric banding has become an increasingly popular surgical option for morbidly obese patients, because of the minimally invasive and easy surgical technique, its reversibility, and the possibility to calibrate the stoma. Gastric necrosis, as a complication of laparoscopic gastric banding, has been only rarely reported. Herein described is the case of a 45-year-old obese patient with gastric necrosis occurring 2 years after the placement of the band. After initial conservative management, the patient underwent urgent surgery. A huge anterior gastric prolapse through the band was found to be responsible for necrosis of the herniated stomach. An upper polar gastrectomy was performed. The mechanisms responsible for this life-threatening complication are discussed.     

Safety and feasibility of revisional laparoscopic surgery for morbid obesity: conversion of open silastic vertical banded gastroplasty to laparoscopic adjustable gastric banding

Background: Since the 1980s, bypass operations have been largely replaced by gastric restrictive operations. One of the most commonly performed operations for gastric restriction is vertical banded gastroplasty (VBG). However, the results are often disappointing. Adjustable gastric banding (AGB) is a viable alternative to VBG, and the ability to perform this surgery laparoscopically makes it an attractive option for patients in need of revisional surgery. It allows for refashioning of the gastric pouch in patients with a dilation of the pouch or disruption of the staple line. Methods: A total of 48 patients were referred to our center due to post-VBG weight gain. All patients underwent preoperative evaluation to determine the cause for failure of the operation. All patients found suitable for revisional surgery underwent laparoscopic placement of an adjustable band. Results: All but one of the operations were completed laparoscopically; one patient required conversion to open surgery prior to band placement via laparoscopy. This patient needed a blood transfusion. Postoperative band erosion occurred in one patient; laparoscopy surgery was used successfully for removal of the band and suturing of the stomach. Conclusions: Our short-term results indicate that revisional operation for morbid obesity using laparoscopic AGB is a safe procedure when performed cautiously. It enables early patient mobilization and discharge with good functional results and fewer perioperative complications.
