Abstract
After the initial widespread diffusion, laparoscopic adjustable gastric banding (LAGB) has been progressively abandoned and laparoscopic sleeve gastrectomy (LSG) has become the worldwide most adopted procedure. Nevertheless, recent reports raised concerns about the long-term weight regain after different bariatric techniques. Considering the large LAGB series recorded in our multicentric bariatric database, we analysed the anthropometric and surgical outcomes of obese patients underwent LAGB at a long-term follow-up, focusing on LAGB management. Between January 2008 to January 2018, demographics, anthropometric and post-operative data of obese patients undergone LAGB were retrospectively evaluated. To compare the postoperative outcomes, the cohort was divided in two groups according to the quantity of band filling (QBF): low band filling group (Group 1) with at most 3 ml of QBF, and patients in the high band filling group (Group 2) with at least 4 ml. 699 obese patients were considered in the analysis (351 in Group 1 and 348 in Group 2). Patients in Group 1 resulted significantly associated (p < 0.05) to higher % EWL and quality of life score (BAROS Score), 49.1 ± 11.3 vs 38.2 ± 14.2 and 5.9 ± 1.8 vs 3.8 ± 2.5, respectively. Moreover, patients with lower band filling (Group 1) complained less episodes of vomiting, epigastric pain and post-prandial reflux and significantly decreased slippage and migration rate (p < 0.001 for all parameters). LAGB is a safe and reversible procedure, whose efficacy is primarily related to correct postoperative handling. Low band filling and strict follow-up seem the success' key of this technique, which deserves full consideration among bariatric procedures.

Abstract
BACKGROUND The success of laparoscopic adjustable gastric band (LAGB) is dependent on gradual adjustments over time. The aim of this study is to describe that pattern of LAGB adjustments that are required after surgery. METHODS A non-randomized observational study of consecutive LAGB from a single practise. Patients were sourced from a prospective database. Details of each LAGB adjustment were recorded along with weight loss and complications. RESULTS There were 125 consecutive LAGB between March 2009 and September 2011 (mean age 46.6 ± 11.9 years; 113 female, BMI 42.1 ± 5.9 kg/m(2)). The mean %EBWL was 41.4 ± 19.1 % at 2 years. There was a total of 746 band adjustments with mean 7.1 ± 4.4 per patient. Approximately, a third of patients (34 %) reached optimal volume within 6 months but 49 patients (39 %) still required adjustments beyond a year. Weight loss was maximal prior to the first adjustment (41 % of mean total weight loss). The rate of weight loss decreased down to 1-3 %EBWL between later fills despite repeated increases in band volume. Urgent deflations were required in 63 patients with 24 of these patients having multiple overfills. There were two patients who had gastric prolapse but no other LAGB-related complications occurred in the first 2 years after surgery. CONCLUSIONS LAGB requires a considerable postoperative commitment that may take several months. Overfills are common and may be the result of a false perception that tightening the band will hasten weight loss.

Abstract
Bariatric procedures vary in efficacy, but overall are more effective than behavioral and pharmaceutical treatment. Roux-en-Y gastric bypass causes increased secretion of glucagon-like peptide 1 (GLP-1) and reduces body weight (BW) more than adjustable gastric banding (AGB), which does not trigger increased GLP-1 secretion. Since GLP-1-based drugs consistently reduce BW, we hypothesized that GLP-1 receptor (GLP-1R) agonists would augment the effects of AGB. Male Long-Evans rats with diet-induced obesity received AGB implantation or sham surgery. GLP-1R agonism, cannabinoid receptor-1 (CB1-R) antagonism, or vehicle was combined with inflation to evaluate interaction between AGB and pharmacological treatments. GLP1-R agonism reduced BW in both sham and AGB rats (left uninflated) compared with vehicle-treated animals. Subsequent band inflation was ineffective in vehicle-treated rats but enhanced weight loss stimulated by GLP1-R agonism. In contrast, there was no additional BW loss when CB1-R antagonism was given with AGB. We found band inflation to trigger neural activation in areas of the nucleus of the solitary tract known to be targeted by GLP-1R agonism, offering a potential mechanism for the interaction. These data show that GLP-1R agonism, but not CB1-R antagonism, improves weight loss achieved by AGB and suggest an opportunity to optimize bariatric surgery with adjunctive pharmacotherapy.

Clinical outcomes of the Realize Adjustable Gastric Band-C at 2 years in a United States population. Surg Obes Relat Dis 2013; 9:885-93. [PMID: 23642493 DOI: 10.1016/j.soard.2013.02.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2012] [Revised: 01/21/2013] [Accepted: 02/26/2013] [Indexed: 12/21/2022]
Abstract
BACKGROUND In 2008, the Realize Band (RB) adopted a precurved design (RB-C). We present 2-year outcomes data from the first multiinstitutional study of RB-C. The objective of this study was to analyze weight loss and safety data from bariatric practices in the United States, including academic, nonacademic, public, and private. METHODS The study included adult RB-C patients with a preoperative body mass index (BMI)≥40 kg/m(2) or >35 kg/m(2) with co-morbidity. Exclusions included RB-C's label contraindications for use. Outcomes parameters were percent excess weight loss (%EWL), BMI change, number and volume of band adjustments, and adverse events. RESULTS A total of 231 patients met inclusion/exclusion criteria. Of these, 161 had 24-month data available. Mean %EWL was 44.4%±26.9% (P<.0001). BMI decreased from 44.1±5.7 kg/m(2) to 35.3±6.9 kg/m(2) (P<.0001). Percent EWL varied by preoperative BMI (P = .0002), bariatric practice (P<.0001), aftercare frequency (P = .0004), and band fill frequency (P = .0271), but %EWL was not influenced by gender, race, or age (P>.20 each). Adverse events were dysphagia (21.2%), gastroesophageal reflux (21.6%), and vomiting (30.7%). Incidence of pouch dilation, esophageal dilation, and slippage was ≤1%. Revisions (2.2%) were for unbuckled band, tube kinking, slippage, and suspected band leak (1 each). No erosions, explants, or mortality were reported. CONCLUSION RB-C appears to be as well tolerated and effective as the first generation RB for weight loss. The near 45% EWL at 2 years is consistent with other high-quality publications on the RB. Preoperative BMI and frequency of postoperative care, including frequency of band fills, influence %EWL. Significant weight loss is achievable with RB-C despite variable postoperative management practices. The low morbidity and the absence of mortality at 24 months reflect positively on the RB-C characteristics.

Abstract
INTRODUCTION Laparoscopic bariatric surgery has gradually spread in Japan since it was introduced in 2000. In 2005, we introduced laparoscopic adjustable gastric banding (LAGB) with the LAP-BAND system into Japan. Here, we evaluate our intermediate-term results with the LAP-BAND system. METHODS Between August 2005 and June 2010, 27 Japanese patients with morbid obesity (BMI ≥ 35 kg/m(2) ) underwent LAGB with the LAP-BAND system in our institution. Our patients' average weight was 111 kg and BMI was 41 kg/m(2) . All LAGB procedures were performed through the pars flaccida pathway with band fixation using gastric-to-gastric sutures. The average follow-up period was 48 months. RESULTS All procedures were completed laparoscopically. One early complication (sudden cardiac arrest due to postoperative bleeding) and three late complications (port trouble, megaesophagus, and band slippage) were experienced, and reoperations were performed in three of the patients. Weight loss and percentage of excess weight loss on average were 26 kg and 53% after 3 years and 22 kg and 53% after 6 years, respectively. In line with this good weight loss, comorbidities, especially those of type 2 diabetes and metabolic syndrome were frequently resolved or improved. CONCLUSION LAGB with the LAP-BAND system appears to be beneficial in obese Japanese patients.

Abstract
This retrospective study aimed to evaluate the long-term results of the laparoscopic Roux-en-Y gastric bypass (LRYGB) procedure performed at our department of bariatric surgery. The 126 consecutive patients treated by LRYGB between January 1, 2001 and December 31, 2002 were analyzed in August 2011. Seventy-seven patients (61.1 %), including 18 who had had previous bariatric surgery, were available for evaluation after 9.4 ± 0.6 years (range, 8.7-10.9 years). Eight patients (10.4 %) suffered from type 2 diabetes mellitus (DMII) at the time of surgery. Initial body mass index (BMI) was 40.3 ± 7.5 kg/m(2) (range, 24.5-66.1 kg/m(2)). There was no postoperative mortality, but two patients died of causes unrelated to the surgery. Some 9 % of the patients suffered from internal herniation, despite the closure of potential hernia sites. With time, the patients had the tendency to experience weight regain: percentage of excess BMI lost was 56.2 ± 29.3 % (range, -78.8 to 117.9 %), down from a maximum of 88.0 ± 29.6 % (range, -19.7 to 197.1 %), that had been obtained after a median of 2.0 years (range, 1-8 years). LRYGB was effective for diabetes control in 85.7 % of the affected patients, but, surprisingly, 27.9 % developed new-onset diabetes. The weight regain in this latter patient group was statistically not different from the nondiabetic group. Conversely, four patients required hospitalization for hypoglycemic syndrome. Two patients underwent reversal of their bypass for problems linked to glucose metabolism (one hypoglycemia, one DMII). Patient quality of life was fair. The patient satisfaction remained good in 76 % of the cases.

Abstract
It is well known that maternal obesity has adverse effects on the health of offspring, causing immediate and long-term morbidities. The various types of procedure coming under the heading of bariatric surgery have proved effective in preventing some maternal and foetal complications in morbidly obese pregnant women. This review aims to assess the role, the risks and the benefits of bariatric surgery for mothers and offspring. According to recent findings, pregnancy and neonatal outcomes in morbidly obese women who have undergone bariatric surgery depend to some extent on the type of surgery used. Maternal complications, nutritional defects and intestinal obstruction are more frequently reported after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) than after laparoscopic adjustable gastric banding (LAGB) procedures, whereas caesarean section, preterm delivery and neonatal death are more commonly reported after RYGB than after LAGB. The authors of the only long-term follow-up study conducted on this subject reported that the rate of obesity in the children dropped by 52% after bariatric surgery for the mother, and the cases of severe obesity decreased by 45%. Data on pregnancy and bariatric surgery confirm that the procedure is more effective than dietary measures alone in morbidly obese women, and that pregnancy outcome is generally favorable after surgery. Some studies have indicated, nonetheless, that pregnancies after bariatric surgery are at higher risk: the women affected require special medical attention, particularly as concerns gastrointestinal symptoms and vitamin deficiencies, warranting nutritional/dietary counselling by a multidisciplinary team before, during and after pregnancy.

Abstract
Laparoscopic adjustable gastric banding (LAGB) has rapidly emerged as a popular bariatric procedure because of its safety, efficacy, durability and adjustability. Despite widespread use, there is limited understanding of how it induces weight loss. Previously, it has been classified as a restrictive procedure, physically limiting the patient to a small meal that subsequently slowly empties into the distal stomach. However, the tiny pouch of stomach created above the LAGB appears to be unable to accommodate even the smallest of meals. Therefore, the key mechanism has been hypothesized to be the induction of satiety via, as yet, undefined pathways. The critical question remains: what are the key physiological changes that lead to satiety and weight loss? In successful LAGB patients, a consistent intraluminal pressure at the level of the LAGB of 26.9 ± 19.8 mm Hg is observed. Studies using semi-solid swallows combined with intraluminal pressure recordings have demonstrated that semi-solid transit across the resistance of the LAGB is mediated by repeated esophageal peristaltic contractions (mean 4.5 ± 2.9) that produce episodic flow, interspersed by reflux events. Failed transit results in obstruction and regurgitation, whereas dilatation of the supraband stomach induces severe and intolerable reflux. Overall gastric emptying does not appear to be significantly altered following LAGB. Focused investigations have shown that the supraband stomach is empty of an ingested meal 1-2 min after intake ceases. Considerable progress has been made in understanding the mechanical physiological effects of the LAGB on esophageal and proximal gastric function. These have been correlated with patient outcomes and sensations. On the basis of recent data, it appears that the LAGB activates the peripheral satiety mechanism without physically restricting the meal size. Therefore, it should not be classified as a restrictive procedure. The precise mechanism of weight loss with the LAGB remains to be delineated.

Abstract
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. METHODS Sixty-nine obese women with LAGB (83 pregnancies) were compared with 120 obese women without LAGB and 858 controls. RESULTS By comparison with normal controls, post-LAGB pregnancies had higher rates of gestational hypertension (9.6% vs 2.4%, p < 0.05), preeclampsia/eclampsia (12.0% vs 2.3%, p < 0.001), abortion (10.8% vs 0.3%, p < 0.001), cesarean section (45.9% vs 28.2%, p < 0.01), preterm delivery (17.6% vs 3.6%, p < 0.001), and babies needing neonatal intensive care (20.3% vs 9.0%, p < 0.01). Compared with the no-LAGB obese group, the post-LAGB pregnancies had lower rates of gestational hypertension (9.6% vs 23.5%, p < 0.05), preeclampsia/eclampsia (12.0% vs 20.8%, p < 0.05), and cesarean section (45.9% vs 65.8%, p < 0.01). The post-LAGB obese women gained less weight during the pregnancy (6.6 +/- 7.9 vs 14.8 +/- 10.1 kg, p < 0.001) and experienced less gestational hypertension (14.8% vs 33%), preeclampsia/eclampsia (7.4% vs 14.8%), and macrosomia (4.2% vs 16%) than in pregnancies before LAGB. No significant differences in maternal and fetal outcomes emerged between post-LAGB pregnant women who lost versus those who gained weight during pregnancy. Compared with those no longer morbidly obese, women still morbidly obese after LAGB had a lower weight gain (2.8 +/- 11.8 vs 8.6 +/- 9.5 kg, p < 0.05) and a higher gestational hypertension rate (29.4% vs 8.9%, p < 0.05). CONCLUSION The risks of negative maternal and fetal outcomes for obese women can be reduced by LAGB if the women are closely followed up.

Abstract
BACKGROUND The aim of the study was to evaluate the results of laparoscopic adjustable gastric banding (LAGB) in patients lost to follow-up. METHODS Patients lost to follow-up were identified from a consecutive cohort of 495 patients who underwent LAGB between November 1995 and September 2006. These patients were asked to return to follow-up and their actual weight was assessed. RESULTS Of 93 patients lost to follow-up, 73 were motivated to reattend. Of these, 60 per cent (44 patients) had lost less than 25 per cent of excess weight, compared with 16.3 per cent (P < 0.001), 27.0 per cent (P < 0.001) and 42 per cent (P = 0.026) of patients after 2, 4 and 8 years of regular follow-up. CONCLUSION Patients lost to follow-up are more likely to have poor weight loss, emphasizing the importance of follow-up after LAGB. Outcome after surgery for morbid obesity should include patients lost to follow-up as a measure of overall success.

Abstract
OBJECTIVE The purposes of this study were to assess the utility of barium studies after adjustments of laparoscopically inserted gastric bands and to identify a threshold stomal diameter for predicting which bands should be loosened because of excessive tightening. MATERIALS AND METHODS A total of 246 patients with laparoscopically inserted adjustable gastric bands underwent 668 routine band adjustments and barium studies after each adjustment. Forty-one barium studies of 30 patients with tight bands necessitating readjustment were compared with barium studies of 41 patients acting as controls. Barium studies of nine patients with obstructive symptoms before adjustment were reviewed to correlate stomal diameter with symptoms. The data were analyzed for a threshold stomal diameter below which obstructive symptoms were likely to develop. RESULTS Mean stomal diameters were 2.9 mm for the group with tight bands after routine adjustment, 9.5 mm for the control group, and 5.1 mm for the group with obstructive symptoms. Thirty-nine of the 41 studies of tight bands after routine adjustment showed stomal diameters less than 6 mm. Seven of nine patients with obstructive symptoms and none of the 41 control patients had stomal diameters measuring less than 6 mm. Conversely, 40 of 41 control patients and two of nine patients with obstructive symptoms had stomal diameters greater than 6 mm. In none of the 41 cases in which the band was tight after routine adjustment was the stomal diameter greater than 6 mm. Thus, 6 mm was the threshold stomal diameter below which bands should be loosened. CONCLUSION A stomal diameter of less than 6 mm after routine adjustment of a laparoscopically inserted gastric band can cause obstructive symptoms, so the band should be loosened in these patients. In contrast, a stomal diameter greater than 7 mm is unlikely to cause obstructive symptoms, so band loosening usually is not required.

Abstract
BACKGROUND Little data exists regarding filling regimens for laparoscopic adjustable gastric bands (LAGB). In addition to patient symptoms and weight changes, we have instituted surgeon-performed, real-time fluoroscopic evaluation in our clinical decision making during all band adjustments. OBJECTIVE Our hypothesis is that surgeon-performed, real-time contrast fluoroscopy conducted routinely during all LAGB adjustment results in significant deviations in clinical care. SETTING The study is set at the Academic Referral Center, United States METHODS Fifty-two consecutive patients who underwent LAGB and presented for adjustment were given a questionnaire evaluating obstructive symptoms. The patient's weight loss history was also reviewed. Each patient underwent real-time fluoroscopy performed by the surgeon during adjustment. Data were recorded and compared to final decision to fill, make no adjustment, or remove fluid. RESULTS Patients were, on average, at post-operative visit 5. Sixty-three percent of patients received a fill, 31% had no change, and 6% had fluid removed. On the questionnaire, 15% of patients noted reflux, 10% had dysphagia, and 8% had regurgitation. Eighty percent of patients requested a fill. Thirty-one percent had an abnormality noted on fluoroscopy. Fifteen percent of patients demonstrated esophageal dilation, 15% had a delay of greater than 5 s, 19% had reflux of contrast. Three patients had band displacements on imaging. Additionally, six patients (12%) were not filled based on fluoroscopic findings alone, not predicted by either the survey or historical weight loss. CONCLUSION Surgeon-performed, real-time, fluoroscopy during LAGB adjustment results in significant changes in clinical care that are not predicted by history and weight loss alone. Routine fluoroscopic imaging altered the course of management in 12% of patients and identified three asymptomatic displaced bands.

Abstract
BACKGROUND Nowadays, obesity is frequently an indication for implantation of an adjustable stomach or gastric band. Among the side effects, in addition to band erosion and port chamber complications, pouch dilation in the sense of increasing enlargement of the forestomach and resulting insufficiency of initial surgical measures consistently occurs. Implantation of a soft basket band will prevent this. The objective of this study was to investigate the practical feasibility of the soft basket band. METHODS Ten patients were investigated in an observation study over a period from November 2006 to June 2007. Seven patients were women and three patients were men, with an average age of 43.6 years (25-66 years). RESULTS The average body mass index (BMI) at the time of the operation was 47.4 +/- 5.5 kg/m(2), with an average body weight of 134.5 +/- 24.6 kg. After a median follow-up period of 1 month, an average BMI of 44.9 +/- 5.8 kg/m(2) was achieved, and after 3 months, an average BMI of 41.4 +/- 4.8 kg/m(2). The excessive weight loss was 7.4 +/- 4.3 kg after 1 month and 17.9 +/- 6.4 kg after 3 months. A local wound infection occurred as a complication in one patient. CONCLUSION Laparoscopy procedures enable mortality to be lowered compared to bypass operations with minimal complications and substantial reduction of weight.

Abstract
BACKGROUND To compare the mortality rate of obese patients treated by laparoscopic gastric banding (LAGB) with the mortality rate of matched obese patients observed at medical centers. The net effect of bariatric surgery on total mortality is still controversial. Gastric bypass has been shown to reduce the relative risk of death, but similar data with LABG are still lacking. METHODS The surgical series was composed of 821 patients with a body mass index (BMI) >40 kg/m(2) consecutively treated with LAGB at Padova University, Italy. The reference group was composed of 821 gender-, age-, and BMI-matched patients selected from a sample of 4681 adults with a BMI >40 kg/m(2) observed at 6 Italian medical centers not using surgical therapy. RESULTS The mean follow-up was 5.6 +/- 1.9 and 7.2 +/- 1.2 years in the surgical and reference group, respectively. The vital status was known in 97.6% of the surgical group (8 deaths) and in 97.4% of the reference group (36 deaths). In the surgical group, the percentage of excess weight loss was 39.8% +/- 17.9% 1 year after LAGB and 37.2% +/- 23.8% 5 years after LAGB. The rate of late revisional surgery was 12.2%. Survival was estimated using the Kaplan-Meier method, and the differences between the 2 groups were evaluated using the log-rank test. The survival rate was significantly greater in the surgical group (P = 0.0004). On multivariate Cox analysis, the 5-year relative risk of death in the surgical group, adjusted for gender, age, and baseline BMI, was 0.36 (95% confidence interval 0.16-0.80). CONCLUSION LAGB was associated with a 0% operative mortality rate and 40% stable excess weight loss. LAGB patients had a 5-year 60% lower risk of death than comparable morbidly obese patients.

Abstract
A patient dose survey was carried out measuring the kerma-area product (KAP) values during radiological evaluation in the follow-up of bariatric surgery. The procedures were performed by three radiologists to adjust laparoscopic gastric bands and to detect postoperative complications after Roux-en-Y gastric bypass procedures to treat morbid obesity. Total fluoroscopy time, exposure factors and the overall contribution of fluoroscopy to the accumulated KAP value were recorded. The median KAP values were used to estimate organ doses and effective dose to a standard patient; the radiation risk associated with the procedures was also evaluated. The doses were smaller for one of the three radiologists, owing to a more appropriate beam collimation and a reduction of the screening time. The KAP values ranged from 1.6 to 7.1 Gy cm(2) for the laparoscopic adjustable gastric banding management, and from 3.0 and 8.3 Gy cm(2) for the radiological examinations after gastric bypass. As a whole, the effective doses associated to these procedures were between 0.5 and 2.7 mSv. The organs receiving the highest doses were not only breast, stomach, pancreas and liver, but also lungs, owing to of their high radiosensitivity, significantly contributed to the effective dose.

Abstract
Comprehensive and collaborative longitudinal care is essential for optimal outcomes after bariatric surgery. This approach is important to manage the many potential surgical and medical comorbidities in patients who undergo bariatric surgery. Medical management programs require prompt and often frequent adjustment as the nutritional program changes and as weight loss occurs. Familiarity with the recommended nutritional program, monitoring and treatment of potential vitamin and mineral deficiencies, effects of weight loss on medical comorbid conditions, and common postoperative surgical issues should allow clinicians to provide excellent care. Patients must understand the importance of regularly scheduled medical follow-up to minimize potentially serious medical and surgical complications. Because the long-term success of bariatric surgery relies on patients' ability to make sustained lifestyle changes in nutrition and physical activity, we highlight the role of these 2 modalities in their overall care. Our guidelines are based on clinical studies, when available, combined with our extensive clinical experience. We present our multidisciplinary approach to postoperative care that is provided after bariatric surgery and that builds on our presurgical evaluation.
