Management of band erosion with omental plugging: case series from a 5-year laparoscopic gastric banding experience

Technical Details and Result of a Minimally Invasive Management of Gastric Band Erosions: a Series of 47 Patients

INTRODUCTION

Laparoscopic adjustable gastric banding (LAGB) is proven to be a safe and effective treatment option for obesity in the long term. However, in recent decades, LAGB prevalence progressively decreased worldwide principally due to the incidence and the management of the complications. Understanding the optimal management of the complications becomes therefore of primary importance. The aim of this study is to describe a personal technical, laparoscopic solution of band erosion and to analyze outcomes in 47 patients.

METHODS

From October 1995 to January 2019, 3697 LAGB were performed at our institution. Since November 2011, an original laparoscopic gastric banding removal technique was introduced. All the bands placed in these patients were Lap-Band AP System (Allergan, Irvin, CA). The data of the patients who underwent gastric band removal because of band erosion were retrieved from a prospectively collected institutional database, and used for the present retrospective evaluation.

RESULT

Ninety-four patients (2.5% of the entire casuistic) with eroded band were diagnosed and treated at our institution. Forty-seven patients were treated with the laparoscopic gastric banding removal technique introduced in November 2011. All the operations have been performed laparoscopically with no conversion or intraoperative complications. There were neither major complications nor peri-operative (30 days) mortality.

CONCLUSION

Proper preoperative management and a standardized minimally invasive technique could help to cope with erosion, the most frightening complication of LAGB. Understanding the optimal management of complications and safe reoperation techniques can contribute to a rational use of the LAGB, reversing the current declining tendency.

[Gastric band erosion: Alternative management]

BACKGROUND

Obesity is a public health problem, for which the prevalence has increased worldwide at an alarming rate, affecting 1.7 billion people in the world.

OBJECTIVE

To describe the technique employed in incomplete penetration of gastric band where endoscopic management and/or primary closure is not feasible.

MATERIAL AND METHODS

Laparoscopic removal of gastric band was performed in five patients with incomplete penetrance using Foley catheterization in the perforation site that could lead to the development of a gastro-cutaneous fistula.

CLINICAL CASES

The cases presented include a leak that required surgical lavage with satisfactory outcome, and one patient developed stenosis 3 years after surgical management, which was resolved endoscopically. In all cases, the penetration site closed spontaneously.

DISCUSSION

Gastric band erosion has been reported in 3.4% of cases. The reason for inserting a catheter is to create a controlled gastro-cutaneous fistula, allowing spontaneous closure.

CONCLUSIONS

Various techniques have been described: the totally endoscopic, hybrid techniques (endoscopic/laparoscopic) and completely laparoscopic. A technique is described here that is useful and successful in cases where the above-described treatments are not viable.

Minimally invasive endogastric removal of migrated gastric band after endoscopic failure: how I do it

Intragastric band migration is a rare and late complication of laparoscopic -adjustable gastric banding and should be recognized by all digestive surgeons. Endoscopic removal is most commonly performed, but surgery is an alternative in cases of endoscopic failure. Many different procedures have been reported. We show here (see Video) a fully laparoscopic endogastric procedure through two 5-mm antral gastrotomies. This technique can also be used to remove benign endogastric tumors. The procedure is safe and provides a large endogastric operative area, with no particular morbidity. Endogastric removal through a fully laparoscopic approach should be considered as the first alternative to endoscopic approach.

Early experience with diagnosis and management of eroded gastric bands

PURPOSE

Band erosion is a well-known complication of laparoscopic adjustable gastric band placement. We gained experience with laparoscopic removal of an eroded gastric band.

METHODS

We retrospectively reviewed the operative log of our obesity surgery unit to identify all operations performed for band erosion from March 2009 to May 2011.

RESULTS

During the study period, a total of six of 96 patients (6.3%), five females and one male, were diagnosed with band erosion and underwent surgical removal of the band system. The median time interval from the initial gastric band placement to the diagnosis of band erosion was 8.5 months (range, 7 to 22 months), with most band erosion occurring within the first year (5/6, 83%). The median body mass index at band removal was 28.4 kg/m(2). Upper abdominal pain was the most common symptom (5/6, 83%), and other signs and symptoms were port site infection (3/6, 50%) and loss of restriction and weight regain (1/6, 17%). All eroded bands were removed using laparoscopy. Further complications after laparoscopic removal of the band system were observed in three cases. One patient showed multiple intra-abdominal abscesses requiring insertion of a pigtail catheter for drainage. The other two patients experienced sepsis with localized peritonitis, eventually requiring laparoscopic washout and drainage.

CONCLUSION

Gastric band erosion requires the removal of the gastric band. Laparoscopic removal is technically achievable in the majority of patients with eroded gastric band. The method can be challenging, has potential postoperative complications (fistula, abscess), and should be attempted only by experienced surgeons.

Treatment of band erosion: feasibility and safety of endoscopic band removal

BACKGROUND

Band erosion is reported with a highly variable incidence (0.3-14%) after laparoscopic adjustable gastric banding. Removal of the band is mandatory because the patient regains weight and may become symptomatic, but no consensus exists about the best method, surgical or endoscopic, for this purpose. This study aimed to evaluate the feasibility and effectiveness of endoscopic management of band erosion.

METHODS

In this study, 23 patients were treated for band erosion after gastric banding: 8 from the authors' series of 951 patients (incidence, 0.84%) and 15 referred to the authors' surgical department from other hospitals. The endoscopic method of band removal was used in 20 cases. Because of complications associated with erosion, three patients were submitted instead to laparoscopic removal.

RESULTS

Endoscopic removal of the band was successful for 16 of 20 patients. Four cases required conversion of the procedure to surgery: in one case due to complications with the endoscopic cutting wire and in the three remaining cases due to dense perigastric adhesions blocking the band. The follow-up evaluation of the patients who had the endoscopic removal was uneventful, with quick discharge at resumption of oral feeding. The patients who underwent laparoscopic removal had a longer hospital stay, and one patient had a leak from the anterior gastrotomy.

CONCLUSIONS

Despite a few complications, endoscopic removal seems to be the procedure of choice for the treatment of band erosion. It allows quick resumption of oral feeding and rapid discharge of patients and appears to be safer and more effective than laparoscopic removal. Conversion to surgery is unlikely but possible. Therefore, the authors always recommend that the procedure be performed in the operating room.

Band erosion after laparoscopic gastric banding: a retrospective analysis of 865 patients over 5 years

BACKGROUND

Gastric band erosion is a well-reported complication after laparoscopic adjustable gastric banding (LAGB). The published literature is limited and inconclusive with regard to its management. The authors therefore reviewed all band erosions detected during a 5-year period in a high-volume bariatric practice. Because a significant proportion of the band insertions (65%) were undertaken by an operator beyond his learning curve, the authors hoped to gain a mature, comprehensive understanding of this significant complication.

METHODS

The authors retrospectively reviewed the operative log of the operating theaters in their obesity surgery unit to find all the operations performed on LAGB patients for erosion from January 2003 to December 2007. The clinical notes and electronic records for each patient were reviewed. These data were cross-referenced against the authors' obesity surgery database, and denominator data such as the total number operations performed and demographics were found. Finally, postoperative outcomes were collated from the outpatient follow-up data and telephonic interviews, and the results were analyzed.

RESULTS

From January 2003 to December 2007, a single surgeon performed 865 LAGBs in the authors' unit. The authors identified 18 operations performed for LAGB erosions. The 18 patients (one referred from elsewhere, 14 women) formed the final study cohort (median preoperative body mass index [BMI], 46 kg/m(2)). Of the 17 erosions, 15 occurred relatively early in the series. The patients with the 213 Swedish adjustable gastric bands experienced 12 erosions (incidence, 5.6%) compared with 6 erosions with the 652 LAP-BANDs (incidence, 0.9%). The median time to presentation was 7 months (range, 1-60 months). However, 55% of the erosions (n = 10) occurred within the first year, and only 10% occurred after the second year. The most common presenting symptom was pain followed by weight regain. None of the patients experienced peritonitis. After surgical management of the erosion, three patients had a second LAGB and at this writing are well. Of the remaining patients, 11 are well, but 6 of these patients have returned to their previous weight (4 patients were lost to follow-up evaluation).

CONCLUSIONS

The overall incidence of LAGB erosions in our series was 1.96%. This incidence fell with increasing experience to 0.5% after the initial 300 bands were excluded from the analysis (3 band erosions in the last 565 band insertions). However, further increases in incidence are likely with a longer follow-up period. The most common presentation was abdominal pain followed by weight regain and port-site sepsis. In the authors' hands, laparoscopic omental plugging and band removal through a separate anterior gastrotomy appear to be effective methods for dealing with band erosions. Band erosion is a significant source of morbidity, with at least one-third of the erosion patients in our series not achieving their final goal of weight loss despite appropriate treatment. This study highlights the need for a future prospective randomized study to clarify the apparent strong influence of band design and construction on the etiopathogenesis of band erosion.
