Financial toxicity risk among patients with gastric banding complications in the United States: analysis of the National Inpatient Sample.

BACKGROUND: Laparoscopic adjustable gastric banding (AGB) was historically among the most performed bariatric procedures but has fallen out of favor in recent years due to poor long-term weight loss and high revisional surgery rates. Significant financial hardship of medical care, known as "financial toxicity," can occur from experiencing unexpected complications of AGB. OBJECTIVE: To investigate the risk of financial toxicity among patients being admitted for AGB complications. SETTING: United States. METHODS: All uninsured and privately-insured patients who were admitted for AGB complications were identified from the National Inpatient Sample 2015-2019. Publicly available government data (U.S. Census Bureau, Bureau of Labor, The Centers for Medicare and Medicaid Services) were utilized to estimate patient income, food expenditures, and average maximum out-of-pocket expenditures. Financial toxicity was defined as total admission cost from AGB complications ≥40% of postsubsistence income. RESULTS: Among 28,005 patients, 66% patients had private insurance and 44% patients were uninsured. Median total admission cost was $12,443 (interquartile range $7959-$19,859) and $15,182 for those who received revisional bariatric surgery. Approximately 55% of the uninsured patients and 1% of insured patients were at risk of financial toxicity after admission for banding-related complications. Patients who had an emergency admission, revisional surgery, or postoperative intensive care unit admission were more likely to experience financial catastrophe following admission (P < .01). CONCLUSIONS: About 1 in 2 uninsured patients admitted for AGB-related complications were at risk of financial toxicity. In addition to surgical risks, providers should consider the potential financial consequences of AGB when counselling patients on their choice of surgery.

Endoscopic assessment of morphological and histopathological upper gastrointestinal changes after endoscopic sleeve gastroplasty.

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is a promising bariatric endoluminal procedure. Restriction and shortening of the stomach are obtained by means of non-resorbable full-thickness sutures, thus inducing the formation of several endoluminal pouches in which food can stagnate. The effect of ESG on the upper gastrointestinal tract has never been investigated. OBJECTIVES: This study objectively evaluates endoscopic macroscopic and histopathologic changes within 12-month follow-up (FU) in patients who underwent ESG. SETTING: Retrospective study on a prospective database of patients who underwent ESG at our tertiary referral center between October 2016 and March 2019. METHODS: All consecutive patients undergoing upper endoscopy (EGD) preoperatively and 6 and 12 months after ESG were included. The upper gastrointestinal tract was evaluated for mucosal abnormalities and biopsies were systematically taken. RESULTS: Eighty-six patients were included. EGD results were as follows: esophagitis decreased from 14% preoperatively to 3.6% and 1.2% at 6- and 12-month FU, respectively (P = .001); 19.8% of patients presented preoperatively a type I hiatal hernia <4 cm and showed no size increment or de novo hiatal hernia at 6- and 12-months. The rate of preoperative hyperemic (23.2%) and erosive (3.5%) gastropathy decreased to 9.5% and 1.2% at 6 months and 17.4% and 1.2% at 12 months, respectively. Gastric ulcer (4.7%), duodenal hyperemic mucosa (1.2%) and duodenal micro-ulcerations (2.3%) detected preoperatively were not present at 6- and 12-month EGD. The rate of histopathological disease, which was 68.1% preoperatively, dropped to 29.2% at 12 months, chronic gastritis decreased from 40.3% to 26.4%, acute gastritis from 9.7% to 0%, and acute inflammation on chronic gastritis from 18% to 2.8% (P < .001). CONCLUSION: ESG is a safe procedure that does not promote the new onset of macroscopic and histopathologic abnormalities within 1-year follow-up.

How Bad Is "Bad"? A Cost Consideration and Review of Laparoscopic Gastric Plication Versus Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Recent large-scale studies have concluded that laparoscopic sleeve gastrectomy (LSG) is superior to laparoscopic gastric greater curve plication (LGP) in weight loss outcomes and post-operative complications, but LGP is still being performed due to its purported financial advantage. Our analysis provides an investigation of cost at the time of operation, and a consideration of the financial implications of the complications and percentage of reoperation associated with each procedure. METHODS: A systematic literature search was performed on the electronic medical databases PubMed and Embase. Extraction of data was performed using a pre-made form which included number of subjects, minor complications and rates, major complications and rates, reoperation rate, percent end weight loss, length of operating time, and length of hospital stay. RESULTS: Twenty-eight records were included after screening for inclusion criteria, representing data from 3242 patients (2668 with LGP and 574 with LSG). Minor and major complications of LGP were documented in 28.7% and 7.2% of cases, respectively, and the rate of reoperation was 10.2%. Minor and major complications of LSG were 19.4% and 4.1%, respectively, and the rate of reoperation was 3.3%. Based on analysis of operating time and length of hospital stay means, each LGP operation was calculated to cost $10,730 USD, and LSG cost $14,074. CONCLUSIONS: LGP has higher rates of complications and reoperation, and less %EWL compared with LSG. Despite modest initial cost benefit of LGP, when considering costs associated with the complications and reoperations, we conclude that LSG is superior to LGP in outcome and cost-effectiveness.

Cost-Effectiveness Analysis of Bariatric Surgery for Morbid Obesity.

BACKGROUND: In the USA, three types of bariatric surgeries are widely performed, including laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic adjustable gastric banding (LAGB). However, few economic evaluations of bariatric surgery are published. There is also scarcity of studies focusing on the LSG alone. Therefore, this study is evaluating the cost-effectiveness of bariatric surgery using LRYGB, LAGB, and LSG as treatment for morbid obesity. METHODS: A microsimulation model was developed over a lifetime horizon to simulate weight change, health consequences, and costs of bariatric surgery for morbid obesity. US health care prospective was used. A model was propagated based on a report from the first report of the American College of Surgeons. Incremental cost-effectiveness ratios (ICERs) in terms of cost per quality-adjusted life-year (QALY) gained were used in the model. Model parameters were estimated from publicly available databases and published literature. RESULTS: LRYGB was cost-effective with higher QALYs (17.07) and cost ($138,632) than LSG (16.56 QALYs; $138,925), LAGB (16.10 QALYs; $135,923), and no surgery (15.17 QALYs; $128,284). Sensitivity analysis showed initial cost of surgery and weight regain assumption were very sensitive to the variation in overall model parameters. Across patient groups, LRYGB remained the optimal bariatric technique, except that with morbid obesity 1 (BMI 35-39.9 kg/m2) patients, LSG was the optimal choice. CONCLUSION: LRYGB is the optimal bariatric technique, being the most cost-effective compared to LSG, LAGB, and no surgery options for most subgroups. However, LSG was the most cost-effective choice when initial BMI ranged between 35 and 39.9 kg/m2.

Outcome of three common bariatric procedures in the public sector.

BACKGROUND: In Australia, over 90% of bariatric surgery is performed in the private sector by paying patients with health insurance. The demand for government funded services is overwhelming and data are needed on the efficiency, safety and effectiveness of the current range of bariatric procedures in a public hospital setting. The aim of this study was to document medium term outcomes of gastric banding (laparoscopic adjustable gastric banding (LAGB)), gastric bypass (Roux-en-Y gastric bypass (RYGB)) and sleeve gastrectomy (SG) in a publicly funded programme. METHODS: Primary cases with minimum 18 months' follow up were included. Hospital usage, complications, weight loss and co-morbidity outcomes were compared. RESULTS: A total of 229 patients (125 LAGB, 42 RYGB, 62 SG) were included. Mean weight (body mass index) for LAGB, RYGB and SG was 130.6 (46.3), 137.2 (50.5) and 162.7 (55.2) kg (kg/m2 ), respectively (P < 0.001). Operative time and hospital stay were longest for RYGB and intensive care stay was longest for SG. Major complications occurred at 0.0%, 11.9% and 12.9% (P < 0.001) and major reoperations occurred over 5 years 11.2%, 21.4% and 6.5% (P = 0.064). Mean (standard deviation) excess weight loss was 29.9% (33.1), 75.7% (31.8) and 52.7% (19.7) with mean follow up of 3.6 years and 79.0% complete data. CONCLUSIONS: In our public bariatric programme, LAGB patients perform relatively poorly. An increased focus on SG may be appropriate as weight loss is more reliable, major reoperation rates are low and follow up less important. Our experience should be useful for those considering how best to structure and fund a public bariatric programme.

LEVEL OF THE GUALITY OF LIFE OF THE PATIENTS AFTER ESOPHAGOPLASTY ON THE BASIS OF GASTROINTESTINAL INDEX ASSESSMENT.

The article presents the interview results of 55 patients after esophagoplasty (30 cases - after esophagogastroplasty, 25 cases - after esophagoplasty) using questionnaire GIQLI. The authors came to conclusions about advantages of extirpation of esophagus with esopagogastroplasty compared with subtotal shunt esophagocoloplasty because of high rate of gastrointestinal index of the quality of life and their components in patients after esophagogastroplasty compared with results of patients after esophagoplasty. There was noted an expessed growth in the scales and rise of gastrointestinal index in patients who underwent esophagogastroplasty after 3 years of follow-up.

Patients' perspectives on laparoscopic adjustable gastric banding (LAGB) aftercare attendance: qualitative assessment.

BACKGROUND: Despite recognition of the importance of laparoscopic adjustable gastric banding (LAGB) aftercare for optimal surgical outcomes and the failure of some patients to attend regularly, factors influencing LAGB aftercare attrition have not been thoroughly examined in the literature. METHODS: Patients' perspectives on LAGB aftercare attendance were explored using a qualitative research methodology. Twenty-four LAGB patients who either (1) did not attend aftercare (n = 12) or (2) attended aftercare regularly (n = 12) were interviewed. Data were analysed using grounded theory methods. RESULTS: Four common processes emerged from patients' descriptions: (1) barriers to attendance, (2) purely medical service, (3) non-patient centred approach, and (4) behavioural and psychological aspects of behavioural changes. Regular attendees typically reported (1) a commitment to aftercare, (2) a need to make the band work, (3) regular monitoring motivated attendance, and (4) happiness with the improved health. Non-regular attendees perceived (1) that aftercare is more relevant early on after the surgery, (2) insufficient follow-up from the centre, (3) failure and shame, (4) not comfortable to be vulnerable, and (5) an intention to reconnect. CONCLUSIONS: Patients perceive LAGB post-operative medical management to be professional, effective, and valuable. Patients' difficulty to actively participate during aftercare visits contributes to reduced satisfaction and a range of compromised outcomes. Management of LAGB post-operative patients may be improved with the use of patient-centred strategies that encourage patients' active participation. Further research is required to evaluate the emerged themes and determine whether interventions targeting identified barriers enhance attendance and improve outcomes.

Prospective longitudinal assessment of change in health-related quality of life after adjustable gastric banding.

BACKGROUND: Gastric banding remains a common procedure worldwide. Improving health-related quality of life (HRQOL) has become a major goal in the treatment of patients with chronic diseases, yet there are few comprehensive data regarding the effect of gastric banding on HRQOL. The aim of this study was to evaluate the impact of laparoscopic gastric banding on HRQOL with particular regard to change over time. METHODS: The 262 consecutive patients included between May 2005 and September 2006 in a French multicenter prospective study designed to assess the safety and efficacy of a gastric band were asked to complete the SF36 questionnaire preoperatively and each 6 months during 3 years. The HRQOL scores were compared with community norms, and their longitudinal change was assessed using cross-sectional analysis and mixed-effects linear modeling (individual growth model). RESULTS: One hundred sixty-four patients (63%) provided a preoperative and at least one postoperative SF-36 questionnaire from 12 to 36 months and form the basis of the present study. In all dimensions, the scores of HRQOL were significantly impaired preoperatively and were significantly improved at 3 years. The increase in HRQOL scores was most marked during the first postoperative months; it continued more slowly after 6 months and stabilized after 1 year. The improvement in HRQOL was associated with the decrease in BMI, in all dimensions. CONCLUSION: Gastric banding results in a significant improvement in HRQOL. A return to normal can be expected at 1 year and persists at 3 years. The postoperative improvement in HRQOL is strongly related to weight loss.

Initial experience with laparoscopic sleeve gastrectomy by a novice bariatric team in an established bariatric center--a review of literature and initial results.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a highly successful approach to morbid obesity with low incidence of complications. The literature suggests a learning curve of 50-100 cases for attaining proficiency and reducing the complication rates for laparoscopic bariatric surgery. The aims of this paper were to review the literature of initial cases by bariatric surgeons worldwide and to report the experience of initial 50 cases of LSG by a novice bariatric team in a single center. The objective was to evaluate the outcomes for laparoscopic bariatric surgery in the first 50 patients by a novice team of bariatric surgeons in an already established bariatric surgery program with short-term follow-up. METHODS: All surgeries were done by a new bariatric team who underwent laparoscopic fellowship training under a bariatric team with an experience of over 600 bariatric procedures. Fifty consecutive patients from March 2010 to January 2012 were offered LSG and followed up for a minimum of 6 months. Weight loss and comorbidity resolution were tabulated and assessed. RESULTS: Mean preoperative and postoperative BMIs were 46.6 and 35.7 kg/m2, respectively. There were no life threatening postoperative complications or mortality. The median percent excess weight loss was 50.3% at the end of 6 months. Comorbidity resolution values were 96% for obstructive sleep apnea, 89% for diabetes mellitus, and 87% for joint pains, among the most common comorbidities. CONCLUSION: LSG is effective in achieving weight loss and in improving comorbidities with minimal complications even at the hands of novice bariatric surgeons with good laparoscopic skills and adequate bariatric training.

Assessment of selenium in Roux-en-Y gastric bypass and gastric banding surgery.

BACKGROUND: Until recently, there was limited documented data on both dietary and serum selenium deficiency in bariatric surgery. We performed an evaluation of selenium intake and both serum selenium and glutathione peroxidase (GTP; as a functional measurement of selenium) before and after roux-en-Y (RNY) gastric bypass and gastric banding surgery. METHODS: The endpoints obtained from the subjects included dietary intake of selenium and vitamins E and C, as well as serum levels of selenium, GTP and vitamins E. These were analyzed at pre-surgery (baseline) and 3 and 12 months post surgery. RESULTS: Dietary deficiencies in selenium intake (38.2 % recommended daily allowance) were noted at 3 months, but not baseline or 12 months, in the gastric bypass group. No dietary deficiencies were noted in the lap band group. For both surgeries, there was a significant reduction from baseline to 3 months in both serum selenium and GTP levels (p = 0.033 and 0.0033 respectively). The serum selenium levels and GTP levels both trended back toward baseline values by 12 months without concomitant selenium supplementation. Mean GTP levels were below normal at all three time points while mean serum selenium levels were all at or above normal. CONCLUSIONS: This study shows that RNY gastric bypass and laparoscopic adjustable gastric banding procedures, and accompanying dietary restrictions, increases the risk for disturbances of selenium and GTP homeostasis. Consideration for selenium supplementation at higher levels than the current RDA of 55 mcg daily during the first 3 months and perhaps longer should be studied further.

Cost and validity of early postoperative contrast swallow after laparoscopic adjustable gastric banding.

BACKGROUND: To assess the validity and cost of early routine upper gastrointestinal (UGI) studies after laparoscopic adjustable gastric banding (LAGB) at a university hospital in the United States. Today, although there is widespread use of LAGB, and it is considered a safe procedure, it also can result in some specific early complications. In most centers, an UGI series after bariatric surgery is performed to rule out these potentially dangerous complications. METHODS: From March 2006 to July 2010, 183 LAGB procedures were performed by a single surgeon. All data were collected prospectively in a computerized database and reviewed retrospectively. The patients underwent water-soluble UGI studies during the early postoperative phase (2-24 h) to exclude gastrointestinal perforation, obstruction, and gastric band malposition. RESULTS: No intraoperative complications occurred. One conversion to an open procedure was required because of massive adhesions. A total of 21 postoperative complications (11.5%) occurred. None of the 183 patients who underwent an early UGI series experienced leakage, gastric band malposition, or slippage. The only radiologic abnormality was a stomal obstruction (.5%) requiring reoperation. The total cost for the 183 UGI studies was $54,900. The mean hospital stay was .5 day (range .1-5.6). Approximately 90% of patients were discharged within the first 24 hours. CONCLUSION: The fear of acute perforation or obstruction has been the rationale for obtaining UGI studies after LAGB. We found this to be expensive and of limited value in an experienced center and have created a decisional algorithm to determine when its use is appropriate for symptomatic patients.

An approach to the assessment and management of the laparoscopic adjustable gastric band patient in the emergency department.

OBJECTIVE: As the number of obese people in Australia continues to increase, laparoscopic adjustable gastric banding (LAGB) surgery will become increasingly common. It is important for practitioners involved in the care of such patients to be able to accurately diagnose, and initially manage, pathology relating to the LAGB. METHODS: A retrospective review of 56 presentations in 41 patients with LAGB, who presented to the ED of a major tertiary hospital, was performed. Note was made of presenting symptoms, investigations undertaken, subsequent diagnosis, and initial and definitive management. RESULTS AND DISCUSSION: The commonest presenting symptoms included abdominal pain, nausea, vomiting and dysphagia. The ultimate diagnosis was food bolus obstruction (18 presentations; 32.1%), port infection (11 presentations; 19.6%), band prolapse (9 presentations; 16.1%), band erosion (2 presentations; 3.6%) and subacute bowel obstruction (1 presentation; 1.8%). Food bolus obstruction was best diagnosed clinically. Plain abdominal X-ray was useful to identify prolapse. Infection was best diagnosed with the combination of clinical picture and wound swab. CT scan was helpful when suspecting a deep source of infection. From these data, two algorithms were developed, which can be used as a clinical aide to help practitioners in diagnosing and treating such complications appropriately. CONCLUSION: It is important that health-care professionals are aware of the common presentations of problems following LAGB and have a basic paradigm for initial care. The present study identifies the presenting picture of various complications that can arise postoperatively, and describes an approach to the assessment and management of the LAGB patient in the ED.

[Assessment of fetal vitality and perinatal results in pregnancies after gastroplasty with Roux-en-Y gastric bypass]. / Avaliação da vitalidade fetal e resultados perinatais em gestações após gastroplastia com derivação em Y de Roux.

OBJECTIVE: To study fetal vitality assessed in pregnancies after gastroplasty with Roux-en-Y gastric bypass and verify maternal complications and perinatal results. METHODS: Hospital charts of all pregnancies after gastroplasty with Roux-en-Y gastric bypass were reviewed retrospectively. All cases followed at the specialized prenatal care that gave birth in this institution, between July 2001 and September 2009, were reviewed. The assessment of fetal vitality (cardiotocography, fetal biophysical profile and umbilical artery Doppler velocimetry) performed in the last week before delivery were analyzed. The maternal variables investigated were: demographic data, maternal complications, mode of delivery, complications during delivery and postpartum, maternal blood exams and perinatal results. RESULTS: During the study period 30 pregnancies after gastroplasty with Roux-en-Y gastric bypass were identified and 24 of them had undergone assessment of fetal vitality. All patients presented normal cardiotocography, normal fetal biophysical profile and normal results at the umbilical artery Doppler velocimetry. One case presented with oligohydramnios. The main complication observed was maternal anemia (Hb < 11.0 g/dL, 86.7%). Cesarean section was performed in 21 pregnancies (70%). Delivery complications included one case of adherences, one hematoma and infection of abdominal wall scar and one postpartum hysterectomy for myoma and uterine atony. The proportion of small infants for gestational age was 23.3%. CONCLUSION: Fetal vitality was not compromised in pregnancies after gastroplasty with Roux-en-Y gastric bypass. The main maternal complication was anemia, therefore these women require specific nutritional counseling and a broad evaluation for micronutrient deficiencies at early pregnancy.

Avaliação da vitalidade fetal e resultados perinatais em gestações após gastroplastia com derivação em Y de Roux / Assessment of fetal vitality and perinatal results in pregnancies after gastroplasty with Roux-en-Y gastric bypass

OBJETIVO: Analisar os resultados da avaliação da vitalidade fetal de gestações após gastroplastia com derivação em Y de Roux, verificando as complicações maternas e os resultados perinatais. MÉTODOS: No período de julho de 2001 a setembro de 2009, foram analisados, retrospectivamente, dados de prontuário de pacientes com gestação após gastroplastia com derivação em Y de Roux, acompanhadas em pré-natal especializado e cujo parto foi realizado na instituição. Foram analisados os exames de avaliação da vitalidade fetal (cardiotocografia, perfil biofísico fetal e dopplervelocimetria das artérias umbilicais) realizada na semana anterior ao parto. As variáveis maternas investigadas foram: dados demográficos, complicações clínicas maternas, tipo de parto, complicações no parto e pós-parto, exames hematimétricos maternos e resultados perinatais. RESULTADOS: Trinta gestações após gastroplastia com derivação em Y de Roux foram identificadas e 24 delas foram submetidas à avaliação da vitalidade fetal. Todas as pacientes apresentaram resultados normais na cardiotocografia, no perfil biofísico fetal e na dopplervelocimetria das artérias umbilicais. Houve um caso de oligohidrâmnio. A principal complicação observada foi anemia materna (Hb < 11,0 g/dL, 86,7 por cento). A cesárea foi realizada em 21 pacientes (70 por cento). As complicações do parto incluíram um caso de aderências, um de hematoma e infecção de parede e um de histerectomia pós-parto por miomatose e atonia uterina. A proporção de recém-nascidos pequenos para a idade gestacional foi de 23,3 por cento. CONCLUSÃO: Não houve comprometimento do bem-estar fetal em gestações após gastroplastia com derivação em Y de Roux. A principal complicação materna foi a anemia e essas mulheres requerem aconselhamento nutricional específico com ampla avaliação das deficiências de micronutrientes desde o início da gravidez.

Radiological assessment of complications after laparoscopic suprabursal adjustable gastric banding for morbid obesity.

BACKGROUND: The purpose of this study was to investigate the clinical impact of radiological assessment on delivery of therapy in patients with laparoscopic adjustable gastric banding for morbid obesity who have developed gastroesophageal symptoms or have inadequate excess weight loss. METHODS: Institutional review board approval and informed consent were obtained from all patients. Suprabursal banding was performed in 373 patients who underwent 869 upper gastrointestinal series. The control group comprised 59 asymptomatic subjects from the study population with satisfactory weight loss at follow-up. RESULTS: There were no intra-operative deaths or gastric perforations. A small gastric pouch was found above the band in 13 (22.03%) of the 59 control subjects; the upper limit of the gastric pouch volume was 9.85 ml (mathematical formula for a sphere used). The main postoperative complications included: 21 of 373 (5.63%) gastric portions above the band with a mean volume of 137.98 ml and narrowed stoma of 0.99 mm; 15 of 373 (4.02%) gastric portions above the band with a mean volume of 33.27 ml and open stoma of 4.95 mm; and 16 of 373 (4.28%) tubing disconnection and displacement into the peritoneal cavity. Twenty-one of 21 narrowed-stoma and eight of 15 open-stoma gastric portions underwent repeat surgery, upward herniation of the stomach (from below the band) being found in all 29 cases. CONCLUSION: Our main findings following the use of the suprabursal approach for surgical band positioning suggest that repeat surgery may be worthwhile for all gastric upper portions >10 ml in patients with gastroesophageal symptoms or inadequate excess weight loss.

Cost-effective restrictive bariatric surgery: laparoscopic vertical banded gastroplasty versus laparoscopic adjustable gastric band.

BACKGROUND: Among bariatric restrictive operations, the procedure of choice is still controversial. The aim of this study is to compare the cost of two gastric restrictive procedures: laparoscopic vertical banded gastroplasty (LVBG) and laparoscopic adjustable gastric banding (LAGB). METHODS: This is a prospective nonrandomized study comparing the cost effectiveness of LVBG and LAGB. Fifty-nine LVBG are compared to 83 LAGB performed during the same period, September 2005 and August 2006. Both groups demonstrate similar body mass index range and gender distribution. RESULTS: Cost analysis is evaluated as: preoperative, intraoperative, postoperative, follow-up, and management of complication cost. Both groups have similar preoperative and immediate postoperative cost. The material cost for LVBG is significantly lower than for LAGB ($1,326.42 for LVBG to $3,253.42 for LAGB). This material cost, however, excludes instruments and materials that are used in both procedures. Although both groups have similar postoperative routine visits, LAGB visits require band fills which increase its cost by $28 if fills are by palpation or $179 if by ultrasound. The complications in LAGB were also more severe with four patients returning to the operating room and another one medically managed for pulmonary embolism. These are at a higher cost compared to LVBG where none of the patients require reoperation or readmissions. The rate of percentage excess weight loss in LVBG patients however is more rapid than in LAGB patients. CONCLUSIONS: LVBG required less expensive instruments and materials for the operation and was associated with a higher rate of weight loss and less complications.

Symmetrical pouch dilatation after laparoscopic adjustable gastric banding: incidence and management.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) has commonly been complicated by the problem of band slippage or prolapse. Since popularization of the pars flaccida approach and improved anterior fixation, it is our impression that the problem of symmetrical dilatation of the proximal gastric pouch has become more important. METHODS: We have reviewed the results of a series of 425 LAGB all performed by the pars flaccida approach from June 2003 to October 2007 to analyze the incidence and implications of this new pattern. RESULTS: There were no posterior prolapses, 2 anterior prolapses, and 17 cases of symmetrical pouch dilatation (SPD) (revision rate 4.4%). Teenage patients had a 22% revision rate for SPD. All revisions were completed laparoscopically with no mortality, no significant complications, and a median hospital stay of 1 day. The median weight loss following revisional surgery was not significantly different from the background cohort. CONCLUSION: SPD is the most common reason for revision of LAGB in this series. We postulate that SPD is caused by excessive pressure in the proximal gastric pouch. This may be generated either by eating too quickly or too large a volume or excessive tightening of the band. The radial forces in the pouch may ultimately cause pressure on the phrenoesophageal ligament and a secondary hiatal hernia.
