Laparoscopic Adjustable Gastric Banding in a Morbidly Obese Patient with Situs Inversus Totalis

Laparoscopic adjustable gastric banding is a commonly performed bariatric operation worldwide. The presence of an anatomical variation like situs inversus demands preoperative assessment and preparedness on the part of the surgeon. We report a laparoscopic gastric banding performed on a morbidly obese patient with situs inversus totalis in the Kingdom of Saudi Arabia.     

Recurrent Aspiration Pneumonia after Laparoscopic Adjustable Gastric Banding

Laparoscopic adjustable gastric banding is a popular therapeutic option for morbid obesity. Band slippage, pouch enlargement and esophageal dilatation are occasional late complications of this procedure. There are rare reports of recurrent aspiration after banding. We report a 44-year-old female suffering from dysphagia and aspiration pneumonia 2 years after adjustable banding. Her esophagus was dilated to 6 cm, and videocinematography showed a severe achalasia-like disorder.Withdrawal of fluid from the band should be immediate, and relieved the stomal obstruction in this patient. Aspiration pneumonia is a serious late complication, which is easily treated by deflation of the band.     

Laparoscopic Adjustable Gastric Banding in 1,791 Consecutive Obese Patients: 12-Year Results

Background This study examines 1,791 consecutive laparoscopic adjustable gastric banding (LAGB) procedures with up to 12 years follow-up. Long-term results of LAGB with a high follow-up rate are not common. Methods Between September 1993 and December 2005, 1,791 consecutive patients (75.1% women, mean age 38.7 years, mean weight 127.7 ± 24 kg, mean BMI 46.2 ± 7.7) underwent LAGB by the same surgical team. Perigastric dissection was used in 77.8% of the patients, while subsequently pars flaccida was used in 21.5% and a mixed approach in 0.8%. Data were analyzed according to co-morbidities, conversion, shortand long-term complications and weight loss. Fluoroscopy-guided band adjustments were performed and patients received intensive follow-up. The effects of LAGB on life expectancy were measured in a case/control study involving 821 surgically-treated patients versus 821 treated by medical therapy. Results Most common baseline co-morbidities (%) were hypertension (35.6), osteoarthritis (57.8), diabetes (22), dyslipidemia (27.1), sleep apnea syndrome (31.4), depression (21.2), sweet eating (22.5) and binge eating (18.5). Conversion to open was 1.7%: due to technical difficulties (1.2) and due to intraoperative complications (0.5).Together with the re-positioning of the band, additional surgery was performed in 11.9% of the patients: hiatal hernia repair (2.4), cholecystectomy (7.8) and other procedures (1.7). There was no mortality. Reoperation was required in 106 patients (5.9%): band removal 55 (3.7%), band repositioning 50 (2.7%), and other 1 (0.05%). Port-related complications occurred in 200 patietns (11.2%). 41 patients (2.3%) underwent further surgery due to unsatisfactory results: removal of the band in 12 (0.7%), biliopancreatic diversion in 5 (0.27%) and a biliopancreatic diversion with gastric preservation (“bandinaro”) in 24 (1.3%). Weight in kg was 103.7 ± 21.6, 102.5 ± 22.5, 105.0 ± 23.6, 106.8 ± 24.3, 103.3 ± 26.2 and 101.4 ± 27.1 at 1, 3, 5, 7, 9, 11 years after LAGB. BMI at the same intervals was 37.7 ± 7.1, 37.2 ± 7.2, 38.1 ± 7.6, 38.5 ± 7.9, 37.5 ± 8.5 and 37.7 ± 9.1. The case/control study found a statistically significant difference in survival in favor of the surgically-treated group. Conclusions LAGB can achieve effective, safe and stable long-term weight loss. In experienced hands, the complication rate is low. Follow-up is paramount.

New Approach in Surgical Treatment of Morbid Obesity: Laparoscopic Gastric Banding

Background: gastric banding has been performed for morbid obesity, with the last nine patients having a laparoscopic approach. Materials: forty-five patients who had undergone primary operations for morbid obesity between 1986 and 1993 were selected for retrospective analysis. All patients had undergone gastric banding. Average pre-operative BMI was 50.9 (kg m⁻²) and average pre-operative weight was 135.1 kg. Results: the 3-year mean post-operative BMI reached 28.7 and the 3-year mean post-operative weight loss was 55.7 kg. Blood pressure significantly decreased from the mean 151/96 mmHg to 132/90 mmHg at 1-year follow-up. There were no significant changes noted in the levels of RBC, electrolytes and transaminase. There were post-operative wound-healing complications in 18.1% of the patients, wound discharge in 8.8% and incisional hernia in 8.8% of the patients. In 1993 we commenced laparoscopic gastric banding which enabled us to shorten the hospital stay and decrease post-operative complications. Conclusion: we are achieving the same good weight-loss results with the laparoscopic technique as after ‘open’ laparotomy gastric banding.     

Changes in Body Image Disturbance in Morbidly Obese Patients 1 Year after Laparoscopic Adjustable Gastric Banding

Background The effectiveness of post-surgical weight loss in improving body image disturbance (BID) in morbidly obese patients is still unclear. Providing multidimensional measures of BID and controlling for the effect of co-morbid eating psychopathology may help to clarify this issue. This preliminary study explores whether 1) BID improves 1 year after laparoscopic adjustable gastric banding (LAGB), and whether 2) such improvement is related to post-surgical BMI and/or eating disorder reduction. BID was multidimensionally assessed by means of the Body Uneasiness Test(BUT). Methods 35 obese subjects (mean BMI 45.5) were evaluated prior to and 1 year after LAGB using the BUT, and a standardized interview and questionnaire to assess eating psychopathology. BID and eating habit changes during follow-up were also investigated. Postoperative BUT values were entered as outcome measures (dependent variables) in a series of stepwise multiple regression analyses; BMI and binge eating reduction, baseline BUT scores, gender, age, and age of onset of obesity were tested as independent variables. Results Some aspects of BID (body image overconcern and related avoidance behaviors, compulsive self-monitoring, and overall severity of BID) improved following LAGB, while others (weight phobia, depersonalization, and uneasiness toward body parts) did not. The post-surgical lower levels of the former were predicted by the overall decrease in binge eating symptoms, irrespective of BMI reduction, age, gender, and age of onset of obesity. Conclusions LAGB may ameliorate some BID aspects in morbidly obese patients, and an improvement in eating behaviors may contribute to this effect.     

Outpatient Laparoscopic Adjustable Gastric Banding in Super-obese Patients

Background Laparoscopic adjustable gastric banding (LAGB) is a safe and effective treatment for morbid obesity that is well suited to outpatient surgery. Super-obese patients (BMI ≥50) are often viewed as higher risk patients, with their surgical procedures limited to hospital operating-rooms. We report our experience performing LAGB for super-obese patients in a freestanding ambulatory surgery center and describe the program elements that make this feasible and safe. Methods Database records containing 1,780 consecutive patients from program inception (November 2002 to November 2006) were searched for patients with a BMI >49.9 undergoing an outpatient LAGB and reviewed to identify complications. Results 320 super-obese patients underwent an outpatient LAGB.Mean preoperative weight was 155.2 kg (range 112.3–220.5 kg), and mean BMI was 55.4 kg/m² (range 50.0–71.1 kg/m²). 53 patients (16.6%) had BMI >60. There were no deaths, significant cardiopulmonary complications, significant intraoperative bleeding, conversion to open laparotomy, or hospital admissions. 3 patients (0.1%) developed gastric edema causing transient obstruction, and 1 developed a delayed colon perforation from electrocautery incurred during adhesiolysis. No complication arose or was more difficult to manage as a result of the procedure being done on an outpatient basis. Conclusions Outpatient LAGB can be safely performed in super-obese patients with a complication rate similar to lower BMI patients. Patient selection and preoperative preparation are essential to achieve excellent outcomes. The decision to offer an outpatient LAGB should rest on the overall physiological condition rather than BMI or weight alone.     

Gastric Wall Necrosis following Late Prolapse after Laparoscopic Banding

A 20-year-old female, who had suffered from morbid obesity with a BMI of 41.2, was admitted 3 years after undergoing laparoscopic gastric banding. 3 days before her present admission, she began suffering from abdominal pain without vomiting. On admission investigation, gastric prolapse was diagnosed with complete obstruction of passage through the band. Emergency laparoscopy was performed, which showed devitalization of the stomach above the band. At the operation, the band was removed, and conservative treatment was begun with nasogastric aspiration, total parenteral nutrition, and close observation.     

Bariatric Analysis and Reporting Outcome System (BAROS) Applied to Laparoscopic Gastric Banding Patients

Background: The definition of success and failure of a bariatric procedure should include weight loss as well as improvement in comorbidity and quality of life assessment. The Bariatric Analysis and Reporting Outcome System (BAROS), introduced by Oria and Moorhead in 1997, seems to provide a standard for comparison in the surgical treatment of morbid obesity. Methods: 180 morbidly obese and super-obese patients, who underwent laparoscopic gastric banding (lap-band) at our institutions and had a follow-up > 18 months (19-55 months) were evaluated with BAROS. Results: The patients were divided into four outcome groups (failure, fair, good, and excellent) based on a scoring table that adds or subtracts points while evaluating three main areas: percentage of excess weight loss, changes in medical conditions, and assessment of quality of life. Points were deducted for complications and reoperative surgery. Conclusions: The BAROS outcome system has proved to be a useful instrument in evaluating midterm results in our series of lap-band patients.     

Plasma Protein Carbonyl and Thiol Stress Before and After Laparoscopic Gastric Banding in Morbidly Obese Patients

Background The aim of this study is to examine the relationship between oxidative plasma protein and thiol stress and weight loss after laparoscopic adjustable gastric banding (LAGB). Methods Plasma protein carbonyl (PCO) concentration as a marker of protein oxidation, plasma thiol (PSH) and erythrocyte glutathione concentration (GSH, major intracellular thiol), as an antioxidant and metabolic markers, such as Homeostatic Model Assessment – Insulin resistance (HOMA-IR), BMI and plasma lipids were determined in morbidly obese patients (n 22, mean age 34.7 ± 11 years, BMI 48.4 ± 6.4 kg/m²) at baseline and 1 and 6 months after operation. Baseline levels in patients were also compared with the levels in agematched controls (n 20, BMI 21.3 ± 1.8 kg/m²). Plasma PCO and thiols and erythrocyte GSH concentrations were determined spectrophotometrically. Results Plasma PCO were significantly higher and plasma and erythrocyte thiol concentrations were significantly lower in morbidly obese patients than in controls (for each comparison, P < 0.01). BMI, plasma triglycerides and HOMA-IR were positively correlated with plasma PCO and negatively correlated with plasma P-SH and erythrocyte GSH (for each comparison, P < 0.01). Plasma HDL-cholesterol levels were positively correlated with plasma erythrocyte GSH (r = 0.405, P < 0.01) and negative correlated with plasma PCO (r = −0.273, P < 0.01). One and 6 months after the LAGB operation, total weight loss was 13.2 ± 6.3 and 35.5 ± 7.5 kg, respectively. Plasma PCO concentrations were decreased and P-SH and erythrocyte GSH concentrations were elevated following weight loss (for each, P < 0.01). Only plasma P-SH levels were restored to the control levels 6 months after LAGB. Conclusions Obesity and insulin resistance appear to be associated with plasma protein oxidation and thiol concentrations. Protein and thiol oxidative stress was improved by weight loss after LAGB in the short-term.     

The Effects on Obesity Related Peptides of Laparoscopic Gastric Band Applications in Morbidly Obese Patients

Background: The aim of this study was to examine the relationship between weight loss and resistin, apelin, chemerin, and visfatin after laparoscopic adjustable gastric banding (LAGB). Methods: The study group consisted of 19 patients who were operated on for morbid obesity (BMI: 48.7 ± 6.6 kg/m²), and 22 healthy, normal-weight (BMI: 22.9 ± 2.5 kg/m²) subjects formed the control group. We obtained blood samples from the study subjects at three different times: before undergoing surgery and at one month and 6 months after surgery. Blood was obtained once from the control group. Results: Significant weight loss was achieved at one and 6 months after surgery. Plasma levels of apelin, resistin, chemerin, and visfatin were higher in morbidly obese patients compared with the control group. Obesity-related peptides decreased one month and 6 months after surgery. Conclusions: Elevated plasma resistin, apelin, chemerin, and visfatin levels in morbidly obese patients are gradually reduced after weight loss. According to these findings, LAGB surgery is found to be an important and efficient means for morbidly obese patients both to lose weight and to develop a better metabolic risk profile in a short time period.     

Alternative Technique for Creation of a Proximal Gastric Pouch in Laparoscopic Adjustable Silicone Gastric Banding

Background: Laparoscopic adjustable silicone gastric banding (LASGB) has become a widely used procedure for the treatment of morbid obesity. The original operation, as described by Kuzmak, has been subjected to modifications. Construction of a proximal gastric pouch is an important part of the operation. Until now, we used the technique of Niville. Since this was often complicated by gastric bleeding and/or serosal tears, we developed a new technique to construct a pouch. Surgical Technique: A new technique, using a thread previously fixed to that portion of the fundus that will be used to construct the pouch, is described. Conclusion: A safe and easy adaptation of the LASGB technique is proposed to create the gastric pouch.     

Orally Administered Ranitidine Plasma Concentrations before and after Biliopancreatic Diversion in Morbidly Obese Patients

Background: Patients undergoing biliopancreatic diversion (BPD) may develop gastric ulcers, particularly within the first postoperative year. The prophylactic use of antisecretory compounds at the usual therapeutic doses, mainly conventional H₂-receptor antagonists such as ranitidine, may reduce the incidence of this complication, which occurs in ∼5% of patients after BPD. Methods: The authors measured the plasma concentrations of ranitidine (300 mg orally) in obese patients, before and 8 months after BPD, and in control subjects of normal weight. The study included 11 obese patients undergoing BPD (age 45 ± 14 years; preoperative and postoperative weights 124 ± 21 and 92 ± 11 kg) and 10 normal-weight subjects (age 37 ± 13 years, weight 67 ± 9 kg). Results: Postoperative ranitidine plasma concentrations showed only minor differences from preoperative levels, with slightly higher maximum concentrations occurring sooner. The mean area under the curve was on the average 30% higher than preoperatively. All parameters, however, were similar to those in control subjects. Conclusions: BPD per se does not greatly affect the pharmacokinetic behavior of ranitidine, and therefore a conventional dosage regimen appears adequate for the prophylaxis and therapy of gastric ulcers associated with this operation.     

Impact of Laparoscopic Adjustable Gastric Banding on Obesity Co-morbidities in the Medium- and Long-Term

Background The authors evaluated the impact of laparoscopic adjustable gastric banding (LAGB) on obesity-associated diseases in a series at 3 to 8 years postoperatively, namely diabetes, pulmonary disease, hypertension and knee joint pain. Methods 145 morbidly obese patients underwent LAGB with mean age 38 years and preoperative BMI 48.5 kg/m2 (range 34–77). Changes in BMI and excess BMI loss (EBL) were evaluated. Results 138 of the 145 patients (95%) were available for full follow-up. At last follow-up, BMI had dropped to 34.0 ± 6.4 SD kg/m², and mean EBL was 61.9 ± 26.1%. Prevalence of obesity-associated disease was significantly reduced: diabetes decreased from 10% to 4%, treatment-requiring pulmonary disease from 15% to 5%, hypertension from 43% to 27%, and knee pain from 47% to 38%. Conclusion Following gastric banding, >75% of patients suffering from obesity-related disease had significant decrease or resolution of their co-morbidities.     

Stoma Adjustable Silicone Gastric Banding: Results in 111 Consecutive Patients

From April 1990 through December 1992, 111 patients (80 females, 31 males, mean age 38 years, range 16-60) underwent stoma adjustable silicone gastric banding (SASGB) at the Department of Surgery, University Hospital, Padua, Italy. Patients' characteristics were: mean height 166 ± 8 cm; mean body weight (BW) 129.1 ± 21.6 kg; mean body mass index (BMI) 46.4 ± 6.3 kg/m²; mean percentage of ideal body weight (%IBW) 206.2 ± 27. Eighty-eight patients were morbidly obese and 23 super obese. All patients were available for follow-up. Median follow-up was 18.8 months (range 12-44). At 1 year (103 patients), mean postoperative BW, BMI, %IBW and excess weight lost (%EWL) were 101.5 ± 20 kg, 36.5 ± 6 kg/m², 164 ± 30 and 40.8 ± 19 respectively; at 2 years (58 patients) 92.3 ± 19 kg, 33.1 ± 6 kg/m², 148.8 ± 28, 52 ± 23, respectively, and at 3 years (26 patients) 86.9 ± 14 kg, 31.4 ± 5 kg/m², 141.5 ± 25 and 63.6 ± 20 respectively. The overall postoperative mortality rate was zero and the early morbidity rate 9%. Late complications were band slippage (two patients), stoma stenosis with pouch dilatation (seven patients), band erosion (one patient), reservoir leakage (three patients) and reservoir infection (two patients). Surgical revision was performed in ten (9%) patients, two of whom required band removal. Most complications occurred in patients who underwent SASGB during our initial experience. Our findings confirm that SASGB is a safe and effective surgical means of achieving weight reduction.     

Late Pouch Dilation after Laparoscopic Adjustable Gastric and Esophagogastric Banding: Incidence, Treatment, and Outcome

Background: Pathologic late pouch dilation is the most frequent complication following gastric banding procedures for morbid obesity. In this study, possible predictive factors were sought. The treatment of these complications and the final outcome are discussed. Methods: Between December 1994 and December 1997, 171 patients underwent laparoscopic adjustable banding for morbid obesity. 40 patients underwent classic gastric banding (Group 1), and 131 patients underwent esophagogastric banding (Group 2). Results: Pouch dilation developed in 6 patients (15%) in Group 1 and 12 patients (9.2%) in Group 2. There were no significant predictive factors, although the complication occurred more frequently in patients with presurgical hiatus hernia. The type of dilation was different for each group, as was the surgical treatment. Laparoscopic repositioning of the band was always possible and was uncomplicated. The long-term outcome has been good, and weight loss has been maintained. Conclusions: A frequent complication following banding procedures for morbid obesity is pathologic late pouch dilation. In experienced hands, when appropriate surgical treatment is carried out, this is not a major problem. Nevertheless, efforts should be made to decrease the number of late dilations.     

Markers of Bone and Calcium Metabolism Following Gastric Bypass and Laparoscopic Adjustable Gastric Banding

BACKGROUND: Several studies have suggested that morbid obesity is associated with vitamin D deficiency and elevated parathyroid hormone (PTH). Studies have also suggested that there is an increase in vitamin D deficiency, bone resorption, and elevated PTH after gastric bypass surgery. Few studies have evaluated markers of bone and calcium metabolism after laparoscopic adjustable gastric banding or compared these results to those after gastric bypass. METHODS: Data on all patients undergoing primary gastric bypass (GBP; n = 979) and laparoscopic adjustable gastric banding (LAGB; n = 269) procedures at a tertiary-referral center from June 1996 through March 2005 were reviewed from a prospective database. Only patients with 25OH vitamin D levels available were included in this study (n = 534; GBP = 403, LAGB = 131). All patients were advised to take at least 1,200 mg calcium and 800-1,200 IU of vitamin D daily before and subsequent to their operation. Markers for bone metabolism [25OH Vitamin D, corrected serum calcium, alkaline phosphatase (AP), and PTH] were evaluated preoperatively and 3, 6, 12, and 24 months postoperatively. An analysis of variance and chi-square were performed to determine differences between the operative groups. Linear regression analysis was performed to evaluate the relationship between preoperative body mass index (BMI) and 25OH vitamin D and PTH levels and between percent excess weight loss and 25OH vitamin D and PTH after surgery. RESULTS: Sixty-four percent of all patients presented with vitamin D deficiency (<20 ng/ml) and 14% presented with elevated PTH preoperatively. Mean 25OH vitamin D levels and AP levels increased significantly after GBP surgery (vitamin D, 17 to 25 ng/ml 12 months post-op; AP, 80 to 90 IU/L 24 months post-op). Corrected calcium levels remained within normal limits and showed no change over time after both procedures. AP levels significantly increased from 76 IU/l preoperatively to 82 IU/l 6 months after LAGB surgery and then decreased to 59 IU/l 24 months after LAGB surgery. Linear regression analysis of preoperative vitamin D, PTH, and BMI values showed a significant positive relationship between initial BMI and PTH (r = 0.29) and a significant negative relationship between vitamin D and initial BMI (r = -0.19). A significant positive linear relationship between vitamin D and percent excess weight loss was evident 12 and 24 months after GBP surgery (r = 0.39 and 0.57, respectively). A negative relationship was evident between PTH and vitamin D 6 months after GBP surgery (r = -0.35) and 12 months after LAGB surgery (r = -0.61). CONCLUSIONS: These findings suggest that morbid obesity is associated with vitamin D deficiency, and elevated PTH and with adequate supplementation, GBP, and particularly LAGB, patients can improve their bone metabolism abnormalities related to obesity. Furthermore, adequate supplementation for GBP patients may attenuate the increased risk for bone loss associated with malabsorption from the bypass.     

Laparoscopic Adjustable Silicone Gastric Banding: Technique and Results

Background: Kuzmak's Adjustable Silicone Gastric Banding (ASGB) is the least invasive operation available for morbid obesity, and it is one of the more effective. Based on the know-how gained from performing more than 250 ‘open’ procedures, we have developed an original laparoscopic technique, whose main steps are pouch measurement, limited dissection along the lesser and the greater curvature and the application of the retention sutures. Methods: From September 1993 through October 1994, 30 morbidly obese patients underwent laparoscopic ASGB. Results: Mean operative time was 2 h and the post-operative stay 2-3 days. Only one major perioperative complication (stomach slippage) was observed. The weight loss achieved, reported as a variation of Body Weight, Body Mass Index, per cent Ideal Body Weight and per cent Excess Weight Loss was similar to that obtained with the open procedure. Conclusion: This new approach is a major achievement in bariatric surgery, because it combines the minimal invasiveness of laparoscopy with the reversibility and adjustability of ASGB.     

Morbid Obesity and Inflammation: A Prospective Study After Adjustable Gastric Banding Surgery

Background  Inflammatory status underlying obesity seems to be implicated in several aspects of metabolic syndrome. Objective  This study aimed to investigate the association between weight loss achieved by laparoscopic gastric banding (LAGB) surgery, chronic inflammatory markers, and nutritional state. Methods  Thirty-two morbid obese females were enrolled in the study and evaluated at baseline, 1 and 18 months after LAGB surgery. Serum immunoglobulin G (IgG), IgA, IgM, C-reactive protein (CRP), haptoglobin, alpha-1 antitrypsin, total proteins, albumin, prealbumin, transferrin, ferritin, and transferrin soluble receptor were evaluated. In addition, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and fasting glucose were also evaluated. Results  In average, patients presented 18.7% and 63.2% excess body weight loss 1 and 18 months after LAGB, respectively (p < 0.01). CRP and total cholesterol mean levels were elevated (1.03 ± 1.11 mg dL⁻¹ and 2.02 ± 0.41 g L⁻¹) at the presurgery study. CRP mean levels were significantly reduced when compared to reference range (p < 0.01) 18 months after the LAGB surgery. Prealbumin as well as serum total protein mean levels decreased 1 month after surgery (p < 0.01) and values returned to normal at 18 months after surgery. Albumin mean levels showed an increase during the postsurgery evaluations. Serum IgA and IgM concentrations were significantly increased at 1 month after surgery compared to baseline (p < 0.01, both cases). Conclusions  Our results indicate that amelioration of inflammatory markers after LAGB does not seem to negatively impact nutritional status following weight reduction surgery. However, careful attention should be driven to serum IgA. Adequacy of nutritional intake and complete serial laboratory measurements should be always included in the required life-long follow-up of patients surgically treated for morbid obesity.     

Assessment of the Outcome of Laparoscopic Nonadjustable Gastric Banding and Stoma Adjustable Gastric Banding: Surgeon's and Patient's View

Background: The results of nonadjustable gastric banding (NAGB) and stoma adjustable gastric banding (SAGB) in the treatment of morbid obesity are compared. Of 300 patients operated laparoscopically with NAGB since 1993 and of 25 with SAGB since 1994, 65 in the NAGB and 11 in the SAGB group were available for a 3-year follow-up study. Methods: For assessment of the outcome of our laparoscopic approach in terms of weight loss, length of hospitalization, immediate and late postoperative wound complications, postoperative changes in the band and pouch area, were compared in patients from both groups. The patient's opinion on the outcome of the operation and the quality of postoperative digestion was recorded. Results: There was no significant difference in the length of hospital stay and wound complication rate in the two groups or the weight loss at 36 months after surgery. There was a statistically significant lower incidence of postoperative food intolerance and vomiting and a lower rate of immediate and long-term reoperation rate in the SAGB group. Conclusion: SAGB is a method with less postoperative complications in food intolerance and vomiting in comparison with NAGB.     

Results and Complications of Laparoscopic Adjustable Gastric Banding: An Early and Intermediate Experience

Background: Laparoscopic adjustable silicone gastric banding (LASGB) has been performed as the initial procedure for weight reduction in the authors' institution for the past 22 months. The efficacy and safety of the procedure were studied. Methods: Patients were followed up prospectively during the perioperative and long-term course and for complications. Results: 391 patients, aged 16-72 years, with a mean body mass index (BMI) of 43.1 (range 33-66) were operated on. The laparoscopic procedure was completed in all but four. The mean operative time was 78 min (range 36-165), and the mean postoperative hospital stay was 1.2 days (range 1-8). There were four (1%) intraoperative complications: pneumothorax in one patient, bleeding in two patients, and injury to the stomach in one. Early postoperative complications were subphrenic abscess in two patients and band malposition in five. Of the patients operated on, 356 (91%) were available for follow-up. Over an average follow-up period of 13 months (range 1-22), band slippage occurred in 16 patients (4.1%), resistant port infection in 1, and longstanding pain in the port area in 9. There were 2 cases of port migration. A total of 26 (6.4%) reoperations were performed: early band repositioning (5), bleeding port site (1), late band repositioning (13), band removal (5), and local relocation of the port (2). All abdominal operations were performed laparoscopically. During the 18-month follow-up, the average BMI dropped from 43.1 to 29.8. Conclusion: LASGB is a safe procedure, with low early complication rates. Most reoperations may be performed laparoscopically, with subsequent low morbidity and short hospitalizations. On intermediate-term follow-up it seems to be an effective bariatric procedure.
