Preparation of Extremely Obese Patients for Laparoscopic Gastric Banding by Gastric Balloon Therapy

Background: In super, super obese patients (body mass index [BMI] >60), especially those with extreme intra-abdominal fat deposition, the technical difficulties in laparoscopic procedures increase. The purpose of this study was to evaluate whether gastric balloon therapy (GBT) can improve the operative conditions for laparoscopic adjustable gastric banding (LAGB) in extremely obese patients. Materials and Methods: From April 1995 to August 1998, 196 LAGBs were performed. In 15 patients (7 female and 8 male), median age 38.8 years (range 17-54), who had been selected as suitable candidates for bariatric surgery, preoperative GBT was studied. Fourteen patients were extremely obese (BMI 60.2 kg/m² [range 58-72]). One 17-year-old boy with BMI 46.6 kg/m² was also treated. The Bioenterics Intragastric Balloon (BIB) was used. The placement, the volume modification, and the removal of the BIB were performed endoscopically. Close follow-up was possible in 14 patients. After balloon removal, 13 patients underwent LAGB. Results: In 14 of 15 cases, GBT was successful. There was only one ballon dysfunction. The mean weight loss was 18.1 kg, and the median duration of balloon therapy was 16.8 weeks. After balloon removal, body weight started to increase. Conclusions: In our experience, the gastric balloon can improve the conditions for laparoscopic surgery in super and in super, super obese patients. There was no conversion to open surgery. The effect of weight loss is much less than immediately after LAGB. However, after failure of all conservative treatments to reduce the preoperative body weight, the GBT seems to be the last possibility.     

Some Complications After Laparoscopic Nonadjustable Gastric Banding

Background: Bariatric surgery is the only currently available, effective, long-term method for controlling morbid obesity. Gastric banding as one of the possible surgical treatments was repeatedly described during the last 10 years. It is a reversible surgical procedure which is primarily performed laparoscopically. Methods: From 1993 to 1998 at the 1^st Surgical Department Faculty General Hospital Charles University in Prague we performed nonadjustable gastric banding laparoscopically in 487 patients with morbid obesity (body mass index [BMI] 34 to 49 kg/m²). There were 429 females and 58 males in this group. Results: In 487 patients who underwent laparoscopic nonadjustable gastric banding (LNGB): early postoperative complications occurred in 29 cases (5.9%)--swelling of the gastric mucosa at the site of the nonadjustable band. In three cases (0.6%)--gastric perforations, and in two patients (0.4%)-- bleeding from gastric ulceration at the site of the band. Swelling was treated conservatively with a nasogastric tube and antisecretory and antiedematic drugs. Bleeding was treated by gastrofibroscopy and gastric perforation by open suture of the lesion. Late complications after LNGB occurred in eight patients (1.7%)--gastritis or esophagitis (but at the site of the band in only two patients [0.4%]), and in 13 patients (2.7%)--small upper pouch dilatation. In 24 cases (4.9%), we discovered slippage of the anterior stomach wall above the band. In three patients (0.6%), the band migrated through the gastric wall in 6-12 months following surgery. In the majority of cases, treatment of these complications was conservative. In eight patients we removed the band by laparoscopy, and in three patients we removed the migrating band from the stomach by open gastrotomy. Other complications have been treated conservatively by correcting the diet, prokinetic drugs, and antisecretory treatment. Conclusions: According to our long-term results, LNGB by experienced bariatric and laparoscopic surgeons is a viable method with low morbidity. In our 487 patients, there were major complications (necessitating reoperation) in 3.2% and minor complications (treated conservatively) in 10.4%.     

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.     

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.     

Laparoscopic Gastric Banding: preliminary series

Gastric banding as a laparoscopic procedure was performed on 40 morbidly obese patients. This operation matches the advantages of the gastric banding (efficacy, reversibility and low invasivity) with the advantages of the laparoscopic procedure (low surgical risk, short hospital stay and less complications in the short and long term). The maximum follow-up is 6 months and so far the weight loss results are the same as we obtained by the vertical banded gastroplasty of Mason. The greatest problem of laparoscopic gastric banding is to get the right tightness of the band for a stoma of 12-13 mm. In three patients the band was replaced due to stenosis, in two of them by a laparoscopic procedure. The adjustable band of Kuzmak should exclude the risk of stenosis and its use will be tried by the laparoscopic procedure.     

Quality-of-Life Outcome After Laparoscopic Adjustable Gastric Banding for Morbid Obesity

Background: The definition of success and failure of a bariatric procedure should include weight loss as well as improvement of comorbidity and quality-of-life (QoL) assessment. QoL measures changes in physical, functional, mental, and social health in order to evaluate benefits of new programs and interventions. Material and Methods: From April 1995 until March 1999, 287 patients underwent laparoscopic adjustable silicone gastric banding (LASGB) at Northwest Hospital Frankfurt a.M. (Germany). In this study, 100 of 287 patients (preoperative mean BMI 48.3 kg/m²; mean age 35.2 years) with a follow-up >18 month were evaluated. All patients underwent anonymous questionnaire (26 questions with a maximum score of 60) about different aspects of QoL outcome after LSAGB. Results: In this study, 4 of 100 patients refused to give an answer to the QoL questions. Therefore 96 patients were evaluated. The QoL auto-evaluation of the patients shows that QoL generally improved after surgery in 92%. Using the scoring system, 44% of patients have excellent, 52% good, and only 4% bad results. The 4 patients who refused had to be classified as failure. General acceptance of LSAGB is wide, but gastrointestinal side effects are recognizable in more than 78% of operated patients. Successful weight loss is followed by an improvement of comorbidities. Conclusions: Safe, effective bariatric procedures increase the quality of life in morbidly obese patients markedly. Bariatric surgeons are committed to support and help their patients until they reach a new quality of life after obesity surgery.     

Laparoscopic Placement of Adjustable Silicone Gastric Banding: Early Experience

Background: the authors describe a laparoscopic technique for the positioning of stoma adjustable silicone gastric banding (SASGB), which respects the main steps of the open procedure. Methods: (1) patient position: supine with thighs abducted and 30° reverse Trendelenburg; (2) Four 10 mm trocars (supra-umbilical, sub-xiphoid, right upper quadrant, left upper quadrant) and an 18 mm trocar (left subcostal); (3) exposure of the subcardial area; (4) measurement of the pouch; (5) dissection of the lesser and greater curvatures; (6) retrogastric tunnel; (7) introduction and placement of the band; (8) band closure and stoma calibration; (9) retention sutures. Results: results obtained in a first (1992) series of five patients who underwent the laparoscopic application of the regular SASGB and results of a second series (1993-1994) of seven patients in whom the new LAP-ASGB was utilized are reported. Conclusion: this new approach can represent a major achievement in bariatric surgery, as it combines the minimal invasiveness of the laparoscopic approach with the reversibility of SASGB.     

Pregnancy Outcome in Morbidly Obese Women Before and After Laparoscopic Gastric Banding

Background  

Increasing numbers of pregnancies are seen in obese women treated surgically with laparoscopic adjustable gastric banding (LAGB). We compared their maternal and fetal outcomes with obese women without LAGB and normal-weight controls.     

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.     

Why the Operation I Prefer is Adjustable Gastric Banding

The author discusses why he performs adjustable gastric banding. Advantages cited are simplicity, and ability to control weight loss by adjusting stomal diameter.     

Laparoscopic Solution for Early Gastric Cancer in a Morbidly Obese Patient

During preoperative work-up for laparoscopic gastricbypass in a morbidly obese female, gastroscopy visualizedtwo small ulcers in the antrum. Biopsies diagnosedadenocarcinoma of the diffuse type. Stagingwas performed, and endoscopic ultrasonographyshowed early gastric cancer. A laparoscopic neartotalgastrectomy with D1 resection and perigastriclymph node dissection and full omentectomy in combinationwith a gastric bypass, was peformed. Thisapproach respects the oncologic and bariatric principlesand gives a combined solution for the patient.     

Inhibition of C-Reactive Protein in Morbidly Obese Patients After Laparoscopic Sleeve Gastrectomy

BACKGROUND: Obesity is considered a low-grade chronic inflammatory condition as reflected by increased C-reactive protein (CRP) levels. Inflammation is emerging as a predictor of cardiovascular disease and it may be a precursor of the metabolic syndrome. Bariatric surgery is commonly performed as a treatment for morbid obesity offering significant reductions in premature myocardial infarction. Laparoscopic sleeve gastrectomy (LSG) is a relatively new bariatric procedure that is currently used as a definitive procedure for weight loss. The aim of this study is to assess the impact of sleeve gastrectomy on CRP levels. METHODS: This study is part of an ongoing, prospective, cohort study to evaluate LSG impact on iron indices. CRP levels were compared preoperatively and 6 months after surgery. Similarly, demographics including body mass index and excess weight were also compared at these same study points. Data were analyzed using Student paired t test and Pearson product moment correlation analysis. RESULTS: Twenty-nine morbidly obese patients were included. There was significant decrease in body mass index (BMI) between the preoperative and 6-month period (50.9 +/- 13.2 and 35.1 +/- 6.85, respectively; P < 0.001). Also CRP levels were statistically significantly lower at 6 months after surgery (preoperative 12.3 +/- 7.53 mg/L and postoperative 5.6 +/- 4.2 mg/L. P < 0.0001). The significant weight loss as reflected by change in BMI was correlated with the difference between preoperative and postoperative CRP levels. CONCLUSIONS: Massive weight loss in morbidly obese patients induced by LSG causes a significant decrease in CRP levels, which could reduce the risk of cardiovascular diseases in these patients.     

Laparoscopic Adjustable Esophagogastric Banding: a Preliminary Experience

Background: Laparoscopic adjustable gastric banding is an efficient surgical method in the treatment of morbid obesity. In order to reduce the number of complications, we have modified the technique to what we term ‘laparoscopic adjustable esophagogastric banding’. Methods: Between December 1994 and July 1997, 126 laparoscopic adjustable banding procedures were carried out. Of these, 40 underwent a gastric banding operation (group 1), and 86 underwent an esophagogastric banding procedure (group 2). Results: The percentage loss of excess body weight curve was less rapid in group 2 compared to group 1 due to a different strategy in band filling. Follow-up to date shows that no problems with the pouch or the stoma have arisen in the esophagogastric banding group. Conclusions: Laparoscopic adjustable esophagogastric banding is a simpler and safer procedure than laparoscopic adjustable gastric banding. It also works as a very efficient anti-reflux procedure, at least in the short term. It appears to be equally efficient as a weight-reducing operation as gastric banding. Further follow-up of the patients involved is necessary in order to evaluate the results in the longer 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.     

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.

Laparoscopic Adjustable Silicone Gastric Banding vs Laparoscopic Vertical Banded Gastroplasty in Morbidly Obese Patients: Long-Term Results of a Prospective Randomized Controlled Clinical Trial

Background  Aim of the study is to present long-term results of a prospective randomized single-institution clinical trial comparing laparoscopic adjustable silicone gastric banding (LASGB) with laparoscopic vertical banded gastroplasty (LVBG) in morbid obesity. Methods  A total of 100 morbidly obese patients (body mass index 40 to 50 kg/m²) were randomized to LASGB (n = 49) or LVBG (n = 51) and followed up for a minimum of 7 years. Results  Mean operative time was 65.4 min in LASGBs and 94.2 min in LVBGs (p < 0.05); mean hospital stay was 3.7 and 6.6 days, respectively (p < 0.05). Late complication rates were 36.7% in LASGBs vs 15.7% in LVBGs at 3 years (p < 0.05), 46.9% vs 43.1% at 5 years (NS), and 55.1% vs 47.1% at 7 years (NS). Late reoperation rates were 28.6% in LASGBs and 2.0% in LVBGs at 3 years (p < 0.001), 38.8% and 2.0% at 5 years (p < 0.001), and 46.9% and 7.8% at 7 years (p < 0.001). Excess weight loss in LASGBs was 41.8% at 3 years, 33.2% at 5 years, and 29.9% at 7 years; excess weight loss in LVBGs was 60.9%, 57%, and 53.1%, respectively (p < 0.05). Conclusions  This study demonstrates that in a carefully selected group of patients, LVBG is significantly more effective than LASGB in terms of late complications, late reoperations, and long-term results on weight loss.
