Re-operations Following Laparoscopic Adjustable Gastric Banding

Background: Re-operations after laparoscopic adjustable gastric banding operation (LAGB) are band-associated or due to complications of the access-port. Symptoms, diagnostics, operations, and follow-up of patients with re-operations were analyzed. Methods: Between December 1996 and January 2002, 250 morbidly obese patients were treated with LAGB and prospectively evaluated using a standardized protocol. Since June 2000 the pars flaccida technique was applied, since October 2000 with the new 11-cm Lap-Band^?. All adjustments of the band were done under radiological control. Results: Of 250 patients, 39 had to be re-operated because of band-associated complications: 27 laparoscopic re-gastric bandings after 12 (3-26) months because of slippage; 6 laparoscopic removals of the band (band intolerance- 4, pain- 1, pouch dilatation- 1); 12 biliopancreatic diversions with duodenal switch (BPD-DS) after 29 (18-43) months due to pouch and/or esophageal motility disorders (9) or insufficient weight loss (3), in 6 patients after having already performed a re-banding for slippage. 9 revisions of the access-port were done after 6 (2-53) months (disconnection- 3, dislocation- 6). The morbidity of the re-operations was 5.3%: 1 hematoma in the abdominal wall and 1 temporary dysphagia after re-banding, 1 pulmonary embolism following BPD-DS. There have been no deaths. In patients with a minimal follow-up of 3 years (n=92), the yearly re-operation rate was 11-12%. No slippage has occurred with the new 11-cm Lap-Band^?. Conclusion: Re-operations after LAGB for bandassociated complications were frequent but could be performed safely with little morbidity. When the new 11-cm Lap-Band^? was employed, the high slippage rate dropped.     

Long-Term Results of Bariatric Restrictive Procedures: A Prospective Study

Laparoscopic adjustable gastric banding (LAGB) and vertical-banded gastroplasty (VBG) are surgical treatment modalities for morbid obesity. This prospective study describes the long-term results of LAGB and VBG. One hundred patients were included in the study. Fifty patients underwent LAGB and 50 patients, open VBG. Study parameters were weight loss, changes in obesity-related comorbidities, long-term complications, re-operations including conversions to other bariatric procedures and laboratory parameters including vitamin status. From 91 patients (91%), data were obtained with a mean follow-up duration of 84 months (7 years). Weight loss [percent excess weight loss (EWL)] was significantly more after VBG compared with LAGB, 66% versus 54%, respectively. All comorbidities significantly decreased in both groups. Long-term complications after VBG were mainly staple line disruption (54%) and incisional hernia (27%). After LAGB, the most frequent complications were pouch dilatation (21%) and anterior slippage (17%). Major re-operations after VBG were performed in 60% of patients. All re-operations following were conversions to Roux-en-Y gastric bypass (RYGB). In the LAGB group, 33% of patients had a refixation or replacement of the band, and 11% underwent conversion to another bariatric procedure. There were no significant differences in weight loss between patients with or without re-interventions. No vitamin deficiencies were present after 7 years, although supplement usage was inconsistent. This long-term follow-up study confirms the high occurrence of late complications after restrictive bariatric surgery. The failure rate of 65% after VBG is too high, and this procedure is not performed anymore in our institution. The re-operation rate after LAGB is decreasing as a result of new techniques and materials. Results of the re-operations are good with sustained weight loss and reduction in comorbidities. However, in order to achieve these results, a durable and complete follow-up after restrictive procedures is imperative.     

Laparoscopic banding: selection and technique in 830 patients

Background: Laparoscopic adjustable gastric banding (LAGB) with the Lap-Band? has been our first choice operation for morbid obesity since September 1993. Results in terms of complications and weight loss are analyzed. Methods: 830 consecutive patients (F 77.9%) underwent LAGB. Initial body weight was 127.9 ± SD 23.9 kg, and body mass index (BMI) was 46.4 ± 7.2 kg/m². Mean age was 37.9 (15-65). Steps in LAGB were: 1) establishment of reference points for dissection (equator of the balloon inflated with 25 cc air and left crus); 2) creation of a retrogastric tunnel above the bursa omentalis; 3) creation of "virtual" pouch; 4) embedding the band. Results: Mortality was 0, conversion 2.7%, and follow-up 97%. Major complications requiring reoperation developed in 3.9% (36 patients). Early complications were 1 gastric perforation (requiring band removal) and 1 gastric slippage (requiring repositioning). Late complications included 17 stomach slippages (treated by band repositioning in 12 and band removal in 5), 9 malpositions (all treated by band repositioning), 4 gastric erosions by the band (all treated by band removal), 3 psychological intolerance (requiring band removal), and 1 HIV positive (band removed). A minor complication requiring reoperation in 91 patients (11%) was reservoir leakage. 20% of patients who had % excess weight loss <30 had lost compliance to dietetic, psychological and surgical advice. BMI declined significantly from the initial 46.4 ± 7.2 to 37.3 ± 6.8 at 1 year, 36.4 ± 6.9 at 2 years, 36.8 ± 7.0 at 3 years, and 36.4 ± 7.8 at 5 years. Conclusion: LAGB is a relatively safe and effective procedure.     

Adjustable Gastric Banding in a Public University Hospital: Prospective Analysis of 400 Patients

Background: Laparoscopic application of an adjustable gastric band (LAGB) is considered the least invasive surgical option for morbid obesity. It has the advantage of being potentially reversible and can improve quality of life. Method: Between April 1997 and January 2001, 400 patients underwent LAGB. There were 352 women and 48 men with mean age 40.2 years (16-66). Preoperative mean body weight was 119 kg (85-195) and mean body mass index (BMI) was 43.8 kg/m² (35.1-65.8). Results: Mean operative time was 116 minutes (30-380), and mean hospital stay was 4.55 days (3-42). There was no death. There were 12 conversions (3%). 40 complications required an abdominal reoperation (10%), for perforation (n=2), gastric necrosis (n=1), slippage (n=31), incisional hernia (n=2) and reconnection of the tube (n=4). We noticed 7 pulmonary complications (2 ARDS, 5 atelectasis) and 30 minor problems related to the access port. At 2 years, mean BMI had fallen from 43.8 to 32.7 kg/m² and mean excess weight loss (EWL) was 52.7 % (12-94). Conclusion: LAGB is a very beneficial operation with an acceptable complication rate. EWL is 50% at 2 years if multidisciplinary follow-up remains assiduous. Surveillance for late anterior stomach slippage within the band is essential.     

Revision of Failed Laparoscopic Adjustable Gastric Banding to Roux-en-Y Gastric Bypass

Background: The most common bariatric surgical operation in Europe, laparoscopic adjustable gastric banding (LAGB), is reported to have a high incidence of long-term complications. Also, insufficient weight loss is reported. We investigated whether revision to Roux-en-Y gastric bypass (RYGBP) is a safe and effective therapy for failed LAGB and for further weight loss. Methods: From Jan 1999 to May 2004, 613 patients underwent LAGB. Of these, 47 underwent later revisional Roux-en-Y gastric bypass (RYGBP). Using a prospectively collected database, we analyzed these revisions. All procedures were done by two surgeons with extensive experience in bariatric surgery. Results: All patients were treated with laparoscopic (n=26) or open (n=21) RYGBP after failed LAGB. Total follow-up after LAGB was 5.5±2.0 years. For the RYGBP, mean operating time was 161±53 minutes, estimated blood loss was 219±329 ml, and hospital stay was 6.7±4.5 days. There has been no mortality. Early complications occurred in 17%. There was only one late complication (2%) – a ventral hernia. The mean BMI prior to any form of bariatric surgery was 49.2±9.3 kg/m², and decreased to 45.8±8.9 kg/m² after LAGB and was again reduced to 37.7±8.7 kg/m² after RYGBP within our follow-up period. Conclusion: Conversion of LAGB to RYGBP is effective to treat complications of LAGB and to further reduce the weight to healthier levels in morbidly obese patients.     

Outcome after Laparoscopic Adjustable Gastric Banding – 8 Years Experience

Background: Laparoscopic adjustable gastric banding (LAGB) has been our choice operation for morbid obesity since 1994. Despite a long list of publications about the LAGB during recent years, the evidence with regard to long-term weight loss after LAGB has been rather sparse. The outcome of the first 100 patients and the total number of 984 LAGB procedures were evaluated. Methods: 984 consecutive patients (82.5% female) underwent LAGB. Initial body weight was 132.2 ± 23.9 SD kg and body mass index (BMI) was 46.8 ± 7.2 kg/m². Mean age was 37.9 (18-65). Retrogastric placement was performed in 577 patients up to June 1998. Thereafter, the pars flaccida to perigastric (two-step technique) was used in the following 407 patients. Results: Mortality and conversion rates were 0. Follow-up of the first 100 patients has been 97% and ranges in the following years between 95% and 100% (mean 97.2%). Median follow-up of the first 100 patients who were available for follow-up was 98.9 months (8.24 years). Median follow-up of all patients was 55.5 months (range 99-1). Early complications were 1 gastric perforation after previous hiatal surgery and 1 gastric slippage (band was removed). All complications were seen during the first 100 procedures. Late complications of the first 100 cases included 17 slippages requiring reinterventions during the following years; total rate of slippage decreased later to 3.7%. Mean excess weight loss was 59.3% after 8 years, if patients with band loss are excluded. BMI dropped from 46.8 to 32.3 kg/m². 5 patients of the first 100 LAGB had the band removed, followed by weight gain; 3 of the 5 patients underwent laparoscopic Roux-en-Y gastric bypass (LRYGBP) with successful weight loss after the redo-surgery. 14 patients were switched to a "banded" LRYGBP and 2 patients to a LRYGBP during 2001-2002. The quality of life indices were still improved in 82% of the first 100 patients. The percentages of good and excellent results were at the highest level at 2 years after LAGB (92%). Conclusions: LAGB is safe, with a lower complication rate than other bariatric operations. Reoperations can be performed laparoscopically with low morbidity and short hospitalizations. The LAGB seems to be the basic bariatric procedure, which can be switched laparoscopically to combined bariatric procedures if treatment fails. After the learning curve of the surgeon, results are markedly improved. On the basis of 8 years long-term follow-up, it is an effective procedure.     

Laparoscopic Adjustable Gastric Banding versus Open Vertical Banded Gastroplasty: A Prospective Randomized Trial

Background: Laparoscopic adjustable gastric banding (LAGB) and open vertical banded gastroplasty (VBG) are treatment modalities for morbid obesity. However, few prospective randomized clinical trials (RCT) have been performed to compare both operations. Methods: 100 patients (50 per group) were included in the study. Postoperative outcomes included hospital length of stay (LOS), complications, percent excess weight loss (%EWL), BMI and reduction in total comorbidities. Follow-up in all patients was 2 years. Results: LOS was significantly shorter in the LAGB group. 3 LAGB were converted to open (1 to gastric bypass). Directly after VBG, 3 patients needed relaparotomies due to leakage, of which one (2%) died. After 2 years, 100% follow-up was achieved. BMI and %EWL were significantly decreased in both groups but significantly more in the VBG group compared to the LAGB group (31.0 kg/m² and 70.1% vs 34.6 and 54.9% respectively). Co-morbidities significantly decreased in both groups in time. 2 years after LAGB, 20 patients needed reoperation for pouch dilation/slippage (n=12), band leakage (n=2), band erosion (n=2) and access-port problems (n=4). In the VBG group, 18 patients needed revisional surgery due to staple-line disruption (n=15), narrow outlet (n=2) or insufficient weight loss (n=1). Furthermore, 8 VBG patients developed an incisional hernia. Conclusion: This RCT demonstrates that, despite the initial better weight loss in the VBG group, based on complication rates and clinical outcome, LAGB is preferred. It had a shorter LOS and less postoperative morbidity.     

Conversion of failed gastric banding into four different bariatric procedures

BackgroundThe most common bariatric operation in Europe, laparoscopic adjustable gastric banding (LAGB), is reported to have a high incidence of long-term complications. Also, insufficient weight loss is reported. The optimal conversion technique is unknown. Our objective was to report our experience in the conversions of failed laparoscopic gastric banding procedures to 4 different bariatric procedures at a university hospital.MethodsFrom March 2006 to December 2010, 630 bariatric operations were performed. Of these patients, 45 underwent conversion of failed LAGB (n = 38) and nonadjustable gastric banding (n = 7). Using a prospectively collected database, we analyzed these procedures.ResultsThe 45 patients underwent laparoscopic conversion of failed LAGB (n = 38) and nonadjustable gastric banding (n = 7) to 4 different procedures. Of the 45 patients, 18 underwent conversion to laparoscopic sleeve gastrectomy, 18 to laparoscopic Roux-en-Y gastric bypass, 7 to laparoscopic biliopancreatic diversion with duodenal switch, and 2 to laparoscopic biliopancreatic diversion. All conversions but 1 were completed laparoscopically. The mean operating time and hospital stay for laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, laparoscopic biliopancreatic diversion with duodenal switch, and biliopancreatic diversion was 111 ± 28 minutes and 4.3 ± 1.4 days, 195 ± 59 minutes and 3.9 ± 1.5 days, 248 ± 113 minutes, and 5.9 ± 2.6 days, and 203 minutes and 6.5 days, respectively. No patient died. Perioperative complications occurred in 4 patients (9.8%). The mean body mass index decreased from 41.5 ± 8 kg/m² to 31.3 ± 6.8 kg/m² during a mean follow-up period of 13.7 ± 9.6 months. Although laparoscopic biliopancreatic diversion with and without duodenal switch had the greatest preoperative body mass index, they achieved the greatest excess weight loss.ConclusionConversion of LAGB or nonadjustable gastric banding to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic biliopancreatic diversion with or without duodenal switch is feasible and effective to treat the complications of LAGB and to further reduce the weight of morbidly obese patients.     

Laparoscopic Conversion of Laparoscopic Gastric Banding to Roux-en-Y Gastric Bypass: a Review of 70 Patients

Background: The feasibility and outcomes of conversion of laparoscopic adjustable gastric banding (LAGB) to laparoscopic Roux-en-Y gastric bypass (LRYGBP) was evaluated. Methods: From November 2000 to March 2004, all patients who underwent laparoscopic conversion of LAGB to LRYGBP were retrospectively analyzed. The procedure included adhesiolysis, resection of the previous band, creation of an isolated gastric pouch, 100-cm Roux-limb, side-to-side jejuno-jejunostomy, and end-to-end gastro-jejunostomy. Results: 70 patients (58 female, mean age 41) with a median BMI of 45±11 (27-81) underwent attempted laparoscopic conversion of LAGB to an RYGBP. Indications for conversion were insufficient weight loss or weight regain after band deflation for gastric pouch dilatation in 34 patients (49%), inadequate weight loss in 17 patients (25%), symptomatic proximal gastric pouch dilatation in 15 patients (20%), intragastric band migration in 3 patients (5%), and psychological band intolerance in 1 patient. 3 of 70 patients (4.3%) had to be converted to a laparotomy because of severe adhesions. Mean operative time was 240±40 SD min (210-280). Mean hospital length of stay was 7.2 days. Early complication rate was 14.3% (10/70). Late major complications occurred in 6 patients (8.6%). There was no mortality. Median excess body weight loss was 70±20%. 60% of patients achieved a BMI of <33 with mean follow-up 18 months. Conclusion: Laparoscopic conversion of LAGB to RYGBP is a technically challenging procedure that can be safely integrated into a bariatric treatment program with good results. Short-term weight loss is very good.     

Long-term results of laparoscopic adjustable gastric banding for the treatment of morbid obesity

Background: Since the first laparoscopic adjustable gastric banding (LAGB) operation on September 1, 1993, there have been important publications related to this procedure. The majority of the articles reported surgical technique and short-term results. Long-term results of LAGB are lacking. The authors report long-term data (at least 4 years) from 3 major bariatric centers in Belgium that perform LAGB routinely. Methods: The 3 centers applied the same patient selection criteria, the same standard surgical technique, the same laparoscopic band (Lap-Band?) and the same follow-up program. 763 patients have been enrolled. Sex ratio was 22% male/78% female. Mean age was 34 years, and mean preoperative BMI was 42 kg/m². Results:The follow-up rate was 90%, and the minimum follow-up time was 4 years. The average BMI after 4 years was 30 kg/m². Early complications were: gastric perforation 4 (0.5%); large bowel perforation 1 (0.1%); bleeding 1 (0.1%); and conversion to open 10 (1.3%). Late complications were: erosion 7 (0.9%); total food intolerance 59 (8%); access port problems 20 (2.5%); re-operations 80 (11.1%); death 1 (0.1%). Conclusion: Long-term results of LAGB have been rarely reported, although publications on the procedure are copious. Our long-term data found that BMI evolution is good, the complication and re-operation rates are acceptable and the overall long-term results of the Lap-Band? system are good.     

Laparoscopic Bariatric Surgery in Super-obese Patients (BMI>50) is Safe and Effective: A Review of 332 Patients

Background: Bariatric surgery in super-obese patients (BMI >50 kg/m²) can be challenging because of difficulties in exposure of visceral fat, retracting the fatty liver, and strong torque applied to instruments, as well as existing co-morbidities. Methods: A retrospective review of super-obese patients who underwent laparoscopic adjustable gastric banding (LAGB n=192), Roux-en-Y gastric bypass (RYGBP n=97), and biliopancreatic diversion with/without duodenal switch (BPD n= 43), was performed. 30day peri-operative morbidity and mortality were evaluated to determine relative safety of the 3 operations. Results: From October 2000 through June 2004, 331 super-obese patients underwent laparoscopic bariatric surgery, with mean BMI 55.3 kg/m². Patients were aged 42 years (13-72), and 75% were female. When categorized by opertaion (LAGB, RYGBP, BPD), the mean age, BMI and gender were comparable. 6 patients were converted to open (1.8%). LAGB had a 0.5%, RYGBP 2.1% and BPD 7.0% conversion rate (P=0.02, all groups). Median operative time was 60 min for LAGB, 130 min for RYGBP and 255 min for BPD (P<0.001, all groups). Median length of stay was 24 hours for LAGB, 72 hours for RYGBP, and 96 hours for BPD (P <0.001). Mean %EWL for the LAGB was 35.3±12.6, 45.8±19.4, and 49.5±18.6 with follow-up of 87%, 76% and 72% at 1, 2 and 3 years, respectively. Mean %EWL for the RYGBP was 57.7±15.4, 54.7±21.2, and 56.8±21.1 with follow-up of 76%, 33% and 54% at 1, 2 and 3 years, respectively. Mean %EWL for the BPD was 60.6±15.9, 69.4±13.0 and 77.4±11.9 with follow-up of 79%, 43% and 47% at 1, 2 and 3 years, respectively. The difference in %EWL was significant at all time intervals between the LAGB and BPD (P<0.004). However, there was no significant difference in %EWL between LAGB and RYGBP at 2 and 3 years. Overall perioperative morbidity occurred in 27 patients (8.1%). LAGB had 4.7% morbidity rate, RYGBP 11.3%, and BPD 16.3% (P=0.02, all groups). There were no deaths. Conclusion: Laparoscopic bariatric surgery is safe in super-obese patients. LAGB, the least invasive procedure, resulted in the lowest operative times, the lowest conversion rate, the shortest hospital stay and the lowest morbidity in this high-risk cohort of patients. Rates of all parameters studied increased with increasing procedural complexity. However, the difference in %EWL between RYGBP and LAGB at 2 and 3 years was not statistically significant.     

Late Gastric Pouch Necrosis after Lap-Band<Superscript>®</Superscript>, Treated by an Individualized Conservative Approach

Late band slippage has occurred in nearly 3-10% of patients after laparoscopic adjustable gastric banding (LAGB) with an average delay of 13 months. Band slippage can rarely lead to necrosis of the enlarged pouch, a potentially life-threatening condition. We report a female (BMI 39.92 with co-morbidities) who developed acute outlet obstruction 2 years after LAGB placement. After prompt band deflation, an urgent Gastrografin swallow showed stomach slippage without emptying. At re-operation pouch strangulation was discovered. The pouch appeared to be ill-fated, but as no tear was evident on intra-operative assessment, we decided to simply remove the band and drain. The patient was successfully discharged after 8 days, and the last upper endoscopy showed only a large ulcer in the fundus that was healing. Proper and prompt management of symptomatic patients with stomach slippage, with early operation when acute obstruction is evident, can enable a successful stomach-sparing approach.     

Initial experience with two-incision laparoscopic adjustable gastric banding

BackgroundTo introduce the 2-incision technique for laparoscopic adjustable gastric banding (LAGB) and report our experience with 25 consecutive patients. Newer applications of minimally invasive laparoscopic techniques have been touted as revolutionary.MethodsWe have introduced a technique for LAGB that uses 2 skin incisions: 1 incision in the right upper quadrant (2.5 cm) that accommodates 2 trocars (11 and 5 mm) through which the dissection and implantation of the band were undertaken, and a 0.5-cm incision in the left upper quadrant for the 5-mm videoscope. The band reservoir was placed in a subcutaneous pocket through the upper quadrant incision. Previously, we used a standard 5-incision technique: 2 in the right upper quadrant, 2 in the left paramedian, and 1 in the subxyphoid area to retract the liver. The data from 25 consecutive 2-incision LAGB procedures (October 2007 to April 2008) were compared with the data from 19 consecutive standard 5-incision LAGB procedures (July 2007 to October 2007). The data are presented as mean ± SD. The t test was used to compare the mean values, and P <.05 was considered significant.ResultsThe mean estimated blood loss in the 2-incision LAGB was 54 ± 2 mL compared with 17 ± 1 mL in the standard technique (P = .040). The mean operating time for the 2-incision LAGB was 119 ± 1 minutes compared with 103 ± 1 minutes for the standard technique (P = .047). No mortality or procedure-related complications (e.g., erosion, slippage) occurred in the 2 groups.ConclusionTwo-incision LAGB is feasible; however, it is associated with an increased operating time and blood loss. The operating time and blood loss might improve with standardization of the operative technique and introduction of newly designed flexible tip instruments. Additional prospective studies with a larger sample size are needed to assess the efficacy and benefit of the 2-incision technique versus the standard technique.     

Esophageal Dilatation after Laparoscopic Adjustable Gastric Banding: Definition and Strategy

Background: Laparoscopic adjustable gastric banding (LAGB) has become a method of choice worldwide to treat morbid obesity. Long-term complications such as esophageal dilatation require that a relevant strategy for treatment be defined. Esophageal dysmotility is commonly described in morbidly obese patients. Methods: 1,232 patients have undergone LAGB over 9 years (1995–2004), and 162 (13.1%) have had a reoperation for complications (excluding access-port problems): slippage (109), erosion (28), intolerance (25). 80 patients (6.4%) had their band removed, and 10 had a switch to another procedure. Esophageal dilatation has been an isolated cause for removal in 2 patients and an associated cause in 6 patients. Results: There was no significant correlation between esophageal dilatation and insufficient excess weight loss (<25%) after 5 years (37/257:14.3%). 4 stages of dilatation were identified, with the relevant treatment for each, the ultimate alternative being conversion to a laparoscopic gastric bypass. We suggest that esophageal dilatation be a separate issue from pouch dilatation and gastric erosion, and that it be classified as a complication only in severe cases requiring band removal. Most cases can be handled through deflation of the band under radiological control. Conclusion: LAGB can lead to significant esophageal troubles which must remain under scrutiny but generally respond to "radiological management", which also makes LAGB more demanding than other operations in terms of follow-up.     

Complications after Laparoscopic Adjustable Gastric Banding for Morbid Obesity: Experience with 1,000 Patients over 7 Years

Background: Laparoscopic adjustable gastric banding (LAGB) is considered the least invasive surgical option for morbid obesity. It is less efficient than gastric bypass in weight loss, but has the advantage of being potentially reversible and can improve the quality of life if mortality and morbidity are low. Methods: Between 1996 and 2003, 1,000 patients underwent LAGB. There were 896 women and 104 men with mean age 40.4 years (16.3-66.3). Preoperative mean BMI was 44.3 kg/m². Results: There were no deaths. Cumulative rate of complications was 192 (19.2%). 12 were life-threatening (1.2%): gastric perforation (n=4), acute respiratory distress (n=2), pulmonary embolism (n=2), migration (n=3), and gastric necrosis (n=1). 111 patients required an abdominal reoperation (11.1%) for perforation (n=2), slippage (n=78), migration (n=3), necrosis (n=1), esophageal dilatation (n=2), incisional hernias (n=4) and port problems (n=21). Before October 2000, we used the perigastric technique, and the slippage rate was 24% (91 / 378 ).Then, we changed to the pars flaccida approach and the slippage rate fell to 2% (13 / 622). The pars flaccida approach demonstrated safety in relation to both risks of perforation and slippage. Conclusion: The cumulative complication rate increased to 3-4 years, and then decreased with experience and technical improvement. Concerns of long-term follow-up should be migration and esophageal dilatation, which seem to be rare at 3 years.     

The Lap-Band<Superscript>®</Superscript> System in a North American Population

Background: European and Australian results with laparoscopic adjustable gastric banding (LAGB) using the Lap-Band^? (Inamed Health, Santa Barbara, CA) have been impressive, with over 100,000 procedures completed at this writing. However, prior to U.S. FDA approval in June 2001, U.S. patients had to travel out of the U.S. for this procedure. This study reports on a series of U.S. patients who requested off-shore referral for LAGB placement. Methods: 105 U.S. patients were implanted with the Lap-Band System^? in Mexico by one surgeon in a private practice. 70% were implanted with the perigastric approach, while the final 30% were implanted using the pars flaccida approach. Routine postoperative visits, including band adjustments, were completed in a private U.S. clinic where medical staff performed frequent small adjustments as necessary to optimize results. Data were collected from concurrent and retrospective chart reviews and from telephone interviews. Summary statistics provided for baseline measures included mean ± standard deviation. Postoperative measures of weight loss included mean ± standard error. Results: Weight loss results were comparable to international results: 61% EWL at 12 months (n=50), 75% EWL at 24 months (n=37), 72% EWL at 36 months (n=24), and 60% EWL at 48 months (n=7). There were few major complications. Conclusion: Attention to patient management is essential to success, and this study found that appropriately-managed U.S. LAGB patients can be as successful as their international counterparts. Frequent follow-up delivered by a bariatric team with easy access to band adjustments is essential.     

Revisional weight loss surgery after failed laparoscopic gastric banding: an institutional experience

Background

Increasing experience with laparoscopic adjustable gastric banding (LAGB) has demonstrated a high rate of complications and inadequate weight loss. Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) have been reported to be safe and effective in selected patients. The purpose of our study was to evaluate the incidence and outcomes of revisional weight loss surgery (RWLS) after laparoscopic gastric banding at our institution.

Methods

From June 2006 to February 2013, all patients who underwent LAGB and those who required revision were retrospectively analyzed. All procedures were performed by two surgeons with extensive experience in bariatric surgery. Parametric data are presented as mean ± SD; nonparametric data are presented as median and interquartile range (IQR).

Results

During the study period, 256 patients underwent LAGB. A total of 111 patients (43 %) required reoperation. Sixty-one patients (56 women, age = 43.7 ± 12 years) with a BMI of 45.4 ± 6 kg/m² successfully underwent RWLS (53 RYGB, 8 LSG). Indications for RWLS included dysphagia (40 patients, 63 %), inadequate weight loss (17 patients, 27 %), GERD (2 patients, 3 %), gastric prolapse (2 patients, 3 %), and needle phobia (1 patient, 2 %). Two required conversion to an open RYGB due to extensive adhesions. RWLS was undertaken approximately 36.3 [25–45] months after LAGB. Removal of the gastric band and the RWLS were performed in 15 patients with an interval of 3 [1.5–7] months between procedures. Median operative time was 165 [142–184] min. Median hospital length of stay was 2 [2–3] days. Early complications occurred in 11 patients (18 %), including 4 anastomotic leaks. Twelve patients (20 %) presented with late complications requiring intervention. There was one death. At a median follow-up of 12.4 months, excess weight loss was 47.5 ± 27 %, and 48 % of patients achieved a BMI < 33.

Conclusion

LAGB is associated with a high incidence of reoperation. Reoperative weight loss surgery can be performed in selected patients with a higher rate of complications than primary surgery. Good short-term weight loss outcomes can be achieved.     

Graft Survival and Complications after Laparoscopic Gastric Banding for Morbid Obesity—Lessons Learned from a 12-Year Experience

Laparoscopic adjustable gastric banding (LAGB) has been considered by many as the treatment of choice for morbid obesity because of its simplicity and encouraging early results. The aim of this prospective study was to critically assess the effects, complications, and outcome after LAGB in the long-term, based on a 12-year experience. Between June 1998 and June 2009, all patients with implantation of a LAGB have been enrolled in a prospective clinical trial. Results were recorded and classified, with special regard to long-term complications, re-operation rate, and graft survival. LAGB was performed in 167 patients (120 female, 47 male) with a mean age of 40.1 ± 5.2 years. Operative mortality was 0%, overall 1.2% (not band-related). Overall patient follow-up was 94.0%. Mean excess weight loss (EWL) after 1, 2, 5, 8, and 10 years was 31.1 ± 7.5% (p < 0.005), 44.2 ± 6.5% (p < 0.001), 50.3 ± 6.9% (p < 0.001), 51.7 ± 6.3% (p < 0.001), and 48.8 ± 6.0% (p < 0.001), respectively. The non-responder rate (EWL < 30%) after 2, 5, 8, and 10 years was 24.5%, 18.3%, 12.5%, and 16.6%, respectively. The early complication rate (<30 days) was 7.8% (13/167), with 10 minor and three major complications. Late complications (>30 days) occurred in 40.1% (67/167), of whom seven were minor and 60 were major complications (three band infections, two band migrations, 11 band leakages, two slippings/pouch dilatations, two band intolerances, and 40 esophageal dilatations). The overall re-operation rate was 20.4% (34/167). The graft survival of the implanted band after 2, 5, 8, 10, and 12 years was 98.8%, 94.0%, 86.8%, 85.0%, and 85.0%, respectively. The failure rate of the procedure after 2, 5, 8, and 10 years was 25.7%, 24.3%, 25.7%, and 31.6%, respectively. In the present long-term high-participation follow-up study, LAGB is a safe and effective surgical treatment for morbid obesity. However, the high complication, re-operation, and long-term failure rates lead to the conclusion that LAGB should be performed in selected cases only, until reliable criteria for patients at low risk for long-term complications are developed.     

Safety and efficacy of laparoscopic adjustable gastric banding in patients aged seventy and older

BackgroundLife expectancy is increasing, with more elderly people categorized as obese. The objective of this study was to assess the effects of laparoscopic adjustable gastric banding (LAGB) on patients aged≥70 years.MethodsThis was a retrospective analysis of patients aged≥70 years who underwent LAGB at our university hospital between 2003 and 2011. The data included age, weight, body mass index (BMI), and percentage excess weight loss (%EWL) obtained before and after gastric banding. Operative data, length of stay, postoperative complications, and resolution of co-morbid conditions were also analyzed.ResultsFifty-five patients aged≥70 years (mean 73 years) underwent gastric banding between 2003 and 2012. Mean preoperative weight and BMI were 123 kilograms and 45 kg/m², respectively. On average, each patient had 4 co-morbidities preoperatively, with hypertension (n = 49; 86%), dyslipidemia (n = 40; 70%), and sleep apnea (n = 31; 54%) being the most common. Mean operating room (OR) time was 49 minutes, with all patients discharged within 24 hours. There was 1 death at 4 years from myocardial infarction, no intensive care unit admissions, and no 30-day readmissions. Mean %EWL at 1, 2, 3, 4, and 5 years was 36 (±12.7), 40 (±16.4), 42 (±19.2), 41 (±17.1), 50 (±14.9), and 48 (±22.6), respectively. Follow-up rates ranged from 55/55 (100%) at 6 months to 7/9 (78%) of eligible patients at 5 years and 2/2 (100%) at 8 years. Complications included 1 band slip at year 5, 1 band removed for intolerance, and 1 port site hernia. The resolution of hypertension, dyslipidemia, sleep apnea, lower back pain, and non-insulin-dependent diabetes was 27%, 28%, 35%, 31%, and 35%, respectively.ConclusionsLAGB as a primary treatment for obesity in carefully selected patients aged≥70 can be well tolerated and effective with moderate resolution of co-morbid conditions and few complications.     

Reduction in Slippage with 11-cm Lap-Band<Superscript>®</Superscript> and Change of Gastric Banding Technique

Background: Slippage occurs after 2-18% of gastric bandings performed by the perigastric technique (PGT). We investigated the slippage-rate before and after the introduction of the pars flaccida technique (PFT) and the 11-cm Lap-Band^?, and the long-term results of the re-operated patients. Methods: Between Dec 1996 and Feb 2004, 360 patients with a mean BMI of 44 kg/m² were operated. The PGT (n=168) and PFT_9.75 (n=15) groups received the 9.75-cm Lap-Band^?, and the PFT₁₁ group (n=177) received the new 11-cm Lap-Band^?. Follow-up rate was 99%. Results: Slippage occurred in a total of 31 patients from all groups (PGT, n=28, or 17%; PFT_9.75, n=1, or 7%; PFT₁₁, n=2, or 1%). Average yearly re-operation rate for slippage in the first 3 years postoperatively was 3.8%, 2.2% and 0.9%, respectively. Laparoscopic re-banding was necessary for posterior (n=19) or lateral (n=12) slippage. The late postoperative course after re-banding was: uneventful 58%, weight regain 35% and/or esophageal motility disorder 23%, secondary band intolerance 20%, and one persistent posterior slippage. 8 patients (26%) needed biliopancreatic diversion. Conclusion: Since the introduction of the PFT and the 11-cm Lap-Band^?, we observed a significant reduction in slippage rate and no posterior slippage. Re-banding had a less favorable long-term result than did first-procedure banding.
