A study of pain after laparoscopic gastric banding.

BACKGROUND: The introduction of the laparoscopic approach to bariatric surgery has brought similar advantages as those seen in general surgery. There have been no trials assessing postoperative pain after laparoscopic adjustable silicone gastric banding (LASGB). We compared prospectively postoperative pain and outcome in LASGB and laparoscopic cholecystectomy (LC), to determine if morbidly obese patients can expect the same benefits from a laparoscopic approach in gastric banding as those which are known for LC in non-obese and obese patients. METHODS: In a prospectively collected database of 80 patients undergoing LASGB, information including a survey assessing the postoperative pain, the amount of analgetic drugs used, operative reports, laboratory data, and follow-up data was collected. This was compared to an equal number of patients undergoing LC. Postoperatively, all patients received standardized pain medication of 150 mg tramadol per day. Pain was assessed twice on postoperative days 1-3 using a patient questionnaire. RESULTS: Patient characteristics and duration of hospital stay were similar in the two groups. Although there was no significant difference in type and intensity of pain experienced by the patients in either group, the gastric banding patients reported less postoperative pain overall than those in the LC group. CONCLUSION: The analyzed data show that LASGB offers the same advantages as other laparoscopic operations, in that it induces less pain and enables the patient to return quickly to normal activity and work. The advantage over the compared LC group may be due to higher patient motivation, but was not statistically significant.

Is a routine liquid contrast swallow following laparoscopic gastric banding mandatory?

BACKGROUND: The authors assess the value of liquid contrast medium swallow as a method to detect postoperative complications after laparoscopic adjustable gastric banding (LAGB) for the treatment of morbid obesity. METHODS: From January 1996 to January 2001, 350 morbidity obese patients (295 women, 55 men) underwent a LAGB operation. All data were prospectively collected in a computerized databank. All patients underwent a jopomidol swallow (JS) study in the early postoperative phase to exclude perforation of the esophagus or stomach, which is one of the most serious complications occurring after the LAGB operation. Furthermore, the JS was performed to confirm band position and to exclude early pouch dilatation. RESULTS: Out of the 350 LAGB operations, 6(1.8%) early pouch dilatations and 4(1.2%) stomach perforations occurred. All early pouch dilatations were recognized on postoperative JS and immediately repaired laparoscopically. Of the perforations, one was recognized intraoperatively, and the other three were diagnosed postoperatively, either by contrast media extravasation on the JS (two patients) or by computer tomography. CONCLUSION: Presently, all patients undergo routine postoperative JS, which exposes them to radiation, causes patient discomfort, and entails additional costs of approximately 100 US$ per patient. Of the last 250 patients in our series, there have not been any cases of early pouch dilatation and since 1998 only one case of perforation has occurred, which could be easily suspected clinically. Therefore, we believe that in experienced centers, it is not necessary to perform routine postoperative contrast media studies and recommend JS only in cases of complicated postoperative courses.

Effects of adjustable gastric banding on altered gut neuropeptide levels in morbidly obese patients.

BACKGROUND: Patients with gastroesophageal reflux disease (GERD) have alterations of gut neuropeptides, such as neurotensin (N) and motilin (M), which are resolved following antireflux surgery. Obesity is associated with GERD. Since the adjustable gastric band prevents gastroesophageal reflux in morbidly obese patients, this study was performed to investigate plasma levels of N and M before and after adjustable gastric banding (AGB). METHODS: 47 morbidly obese patients were operated laparoscopically using the Swedish AGB. Pre- and postoperatively basal plasma levels of N and M were investigated. Symptoms such as heartburn, regurgitation and dysphagia were documented, and esophageal manometry as well as 24-hour pH-monitoring were performed pre- and postoperatively. 11 non-obese, asymptomatic, age-matched volunteers served as controls. RESULTS: After a median postoperative follow-up period of 268 days, a significant weight reduction was observed. Preoperatively, 14 patients suffered from reflux symptoms. An insufficient lower esophageal sphincter (LES) was found in 8 patients, and 2 patients had impaired esophageal body motility. Pathologic pH-testing was found in 6 patients. Postoperatively, reflux symptoms were present in 4 patients; LES findings and pH-testing were normalized in all patients. However, there was significant impairment of esophageal peristalsis. Preoperatively, levels of N were significantly decreased and levels of M increased compared with control subjects. Postoperatively, there was a significant increase of N and levels of M were normalized. Alterations in gut neuropeptides did not correlate with reflux symptoms, impaired gastroesophageal motility, age, gender or BMI. CONCLUSION: Morbid obesity alters gut neuropeptides, which are resolved by AGB. This may be caused by reduction of hypercaloric nutrition postoperatively rather than by improvement of gastroesophageal reflux.

Pouch dilatation after gastric banding causing gastric necrosis.

BACKGROUND: Early or late pouch dilatations account for a moderate complication rate after restrictive bariatric operations. Various strategies were developed to prevent or treat pouch dilatations. METHODS: A case of necrosis of gastric wall in a concentric dilated pouch following laparoscopic adjustable gastric banding is reported as a severe complication of a conservative treatment attempt. RESULTS: Emergency laparotomy resulted in band removal, partial gastric resection and prolonged hospital stay. CONCLUSION: Conservative strategies in the treatment of pouch dilatations bear the risk of complications, with both failure of the bariatric procedure and critical clinical course. Indication for early operative reintervention is recommended.

Treatment of morbid obesity with laparoscopic adjustable gastric banding affects esophageal motility.

BACKGROUND: Laparoscopic adjustable gastric banding has become the prefered method for the surgical treatment of morbid obesity in Europe. It is not known whether this procedure may induce gastroesophageal reflux and whether it may impair esophageal peristalsis. METHODS: Laparoscopic adjustable gastric banding (Swedish band) was performed in 43 patients (median body mass index [BMI] 42.5 kg/m(2)). Preoperatively and 6 months postoperatively all patients were assessed for reflux symptoms. In addition all patients underwent preoperative and postoperative endoscopy, esophageal barium studies and manometry, and 24-hour esophageal pH-monitoring. RESULTS: The median BMI dropped significantly to 33.1 kg/m(2) (P <0.05). Preoperatively 12 patients complained of reflux symptoms. Mild esophagitis was detected in 10 patients. Postoperatively only 1 patient complained of heartburn and mild esophagitis was diagnosed in another patient. None of the patients had dysphagia. Preoperatively a defective LES and pathologic pH-testing were found in 9 and 15 patients, respectively. These parameters were normal in all of the patients postoperatively. Postoperatively there was significant impairment of LES relaxation and deterioration of esophageal peristalsis with dilatation of the esophagus in some of the patients. CONCLUSION: Laparoscopic adjustable gastric banding provides a sufficient antireflux barrier and therefore prevents pathologic gastroesophageal reflux. However, it impairs relaxation of the LES, leading to weak esophageal peristalsis.

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.

Organ transplantation and obesity: evaluation, risks and benefits of therapeutic strategies.

Obesity is a prevalent health problem that has discernible impact on all fields of surgery. However, little attention is paid in the literature to the underlying relation of surgical, immunological and metabolic links between transplantation and morbid obesity. Pre-operative obesity has been reported to worsen the outcome of organ transplantation. Impairment of graft function as well as decreased patient and graft survival can contribute to this effect. Post-transplant weight gain is common and may be attributed to an imbalance of the adipostatic and appetite stimulating hormones. Reduction of obesity before transplantation has to cope with limited time, increased risk of therapeutic side-effects in patients with end-stage organ failure, and psychosocial stress. Overweight reduction following organ transplantation interferes with diverse effects associated with immunosuppressive therapy. A case of adjustable gastric banding following renal transplantation is presented.

Aberrant left hepatic artery in laparoscopic gastric banding.

BACKGROUND: The aberrant left hepatic artery (ALHA) is an anatomic variation which may be an obstacle in the laparoscopic gastric banding operation. Based on our experience, our mission was to answer the questions: How frequently is an ALHA encountered? Is division necessary? Are there any additional complications in cases where the ALHA is preserved? METHODS: In a prospectively collected database of 270 patients undergoing laparoscopic gastric banding in our unit, information including presence of an ALHA, clinical data, diagnostic work-up, operative reports, laboratory data, and follow-up data were collected. RESULTS: In 48 patients (17.7%) (39 women, 9 men, mean age 39.2 years) an ALHA was observed. Hiatal dissection was not impaired in any of these patients, and none required division of the ALHA. In all but two cases, the band was placed above the ALHA, offering additional stability to the band positioning. In 2 patients (4.1%), the artery was injured during dissection and was divided due to ongoing bleeding. Twenty-two (45.8%) of the ALHAs were of intermediate or large size. Neither pouch dilatation nor band slippage occurred in the above-mentioned group. The two patients with divided hepatic arteries had no postoperative symptoms related to impaired liver function. CONCLUSIONS: ALHA is not an uncommon finding during laparoscopic gastric banding and may be found in approximately 18% of patients. Division can nearly always be avoided and may be required only in selected cases due to bleeding. Patients do not experience clinical complications after division, although liver enzymes may be temporarily elevated, and no monitoring is necessary.

Injection port complications after gastric banding: incidence, management and prevention.

BACKGROUND: Laparoscopic adjustable gastric banding is advocated as a minimal invasive procedure with a low risk profile and high efficacy in the treatment of morbid obesity. Nevertheless, injection port complications are occasionally reported. The aim of this study was to assess port disconnections and port dislodgement with respect to two different implantation techniques. METHODS: Between January 1996 and October 1999 230 patients underwent laparoscopic gastric banding with the Swedish Adjustable Gastric Band (SAGB). In group 1 (118 patients), the injection port was implanted onto the sterno-xiphoid union. In group 2 (112 patients), an additional incision was made to suture the port onto the fascia of the lower third of the sternum. RESULTS: There is a significant reduction in port disconnection between group 1 (9.3 %) and group 2 (0 %). Port dislodgment was observed in one patient in each group. Reoperation was performed under local anesthesia in 11 patients, and general anesthesia was used for laparoscopic tube salvage in two patients. After reconnection, two patients experienced port infection. CONCLUSION: Correct implantation technique of the injection port of the SAGB onto the fascia of the lower third of the sternum reduces the risk for port complications. Technical notes are discussed.

Gastroscopic band removal after intragastric migration of adjustable gastric band: a new minimal invasive technique.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is the most used procedure for bariatric surgery in Europe. Although a low complication rate is reported, band migration within the first 2 years after LAGB is still observed in nearly 5% of cases, requiring operative band removal. To avoid increased risk of complications due to laparotomy, we propose a minimally invasive technique for this purpose. METHODS: We performed this operation in five patients who suffered from band migration after LAGB (1.9% in our series of 211 patients, one patient was operated elsewhere). The described method consists of gastroscopic band and tube removal, combined with removal of the port under local anesthesia. RESULTS: The described procedure was developed in the endoscopy unit without additional equipment. The mean operating-time ranged from 65 to 180 minutes (mean 135 minutes). No perioperative complication were observed. In-patient treatment was necessary for 4 days. CONCLUSIONS: A novel technique for minimally invasive band removal after adjustable gastric band migration is described, offering the patient a low-risk procedure and a better chance for further laparoscopic approaches.
