Past, present, and future: Critical analysis of use of gastric bands in obese patients

The importance of patient selection in bariatric surgery: One not fit for all. Case report of a preventable double severe complication after Laparoscopic gastric banding positioning

•

LAGB presents many severe complications.

•

Wedge resection could allow to preserve a tailored gastric pouch limiting postoperative nutritional defects.

•

Strict postoperative follow-up reduce the risk of severe complications.

Introduction

Laparoscopic adjustable gastric banding (LAGB) is a minimal invasive, effective and reversible procedure, even if it is burdened by life threatening complications.

Presentation of the case

A 39 years-old female patient was admitted to our emergency department for abdominal pain and ileus and underwent an explorative laparoscopy. The LAGB was wrapped around the proximal portion of the stomach determining the erosion and ischemia of the great curvature region. It was removed and a large gastric resection of the great curvature was performed. Subsequently, a gastric leak with pleural abscess occurred with the beginning of the oral diet. It was successfully treated with fasting, intravenous antibiotics and a thoracic tube.

Discussion

LAGB is a restrictive procedure that compartmentalizes the upper stomach by placing a tight adjustable band around it. However severe and multiple complications can also occur. Slippage is one of the most frequent and dangerous complication. Partial gastric resection (comparable to sleeve gastrectomy) or total/subtotal gastrectomy on the limit of the scarring tissue is use requested in the latter case, with a high risk of postoperative leak. A strict postoperative follow-up is mandatory in order to early recognize any severe complications.

Conclusion

Strict follow-up in this special subset of patients, the bariatric ones, is mandatory in order to early identify and correct any postoperative complications, avoiding severe sequelae.

Bariatric Surgery Patients' Perceptions of Weight-Related Stigma in Healthcare Settings Impair Post-surgery Dietary Adherence

Background: Weight-related stigma is reported frequently by higher body-weight patients in healthcare settings. Bariatric surgery triggers profound weight loss. This weight loss may therefore alleviate patients' experiences of weight-related stigma within healthcare settings. In non-clinical settings, weight-related stigma is associated with weight-inducing eating patterns. Dietary adherence is a major challenge after bariatric surgery.

Objectives: (1) Evaluate the relationship between weight-related stigma and post-surgical dietary adherence; (2) understand if weight loss reduces weight-related stigma, thereby improving post-surgical dietary adherence; and (3) explore provider and patient perspectives on adherence and stigma in healthcare settings.

Design: This mixed methods study contrasts survey responses from 300 postoperative bariatric patients with ethnographic data based on interviews with 35 patients and extensive multi-year participant-observation within a clinic setting. The survey measured experiences of weight-related stigma, including from healthcare professionals, on the Interpersonal Sources of Weight Stigma scale and internalized stigma based on the Weight Bias Internalization Scale. Dietary adherence measures included patient self-reports, non-disordered eating patterns reported on the Disordered Eating after Bariatric Surgery scale, and food frequencies. Regression was used to assess the relationships among post-surgical stigma, dietary adherence, and weight loss. Qualitative analyses consisted of thematic analysis.

Results: The quantitative data show that internalized stigma and general experiences of weight-related stigma predict worse dietary adherence, even after weight is lost. The qualitative data show patients did not generally recognize this connection, and health professionals explained it as poor patient compliance.

Conclusion: Reducing perceptions of weight-related stigma in healthcare settings and weight bias internalization could enhance dietary adherence, regardless of time since patient's weight-loss surgery.

Diagnosis and management of early gastric band slip after laparoscopic adjustable gastric banding

Laparoscopic adjustable gastric banding (LAGB) used to be a very popular bariatric procedure at a certain time for the treatment of obesity as it has many advantages and is associated with low morbidity and mortality rates. Complications are often late and are rarely seen by general surgeons due to the limited number of patients, and physicians should be aware of the symptoms. We present a case of a 40-year-old female patient who underwent LAGB and was admitted for a huge gastric pouch dilatation on postoperative day 5. She had a history of food consumption on the fourth day after surgery. She was diagnosed with early gastric band slippage (EGBS). The band was repositioned and gastrogastric sutures were placed to prevent reprolapse of the band. The EGBS is an immediate postoperative complication. Diagnosis of EGBS can be made with oral contrast X-ray studies, and surgical intervention is necessary.

Gastrointestinal Complications After Bariatric Surgery

Bariatric surgery is increasingly being performed in the medically complicated obese population as convincing data continue to mount, documenting the success of surgery not only in achieving meaningful weight loss but also in correcting obesity-related illnesses. Several surgical procedures with varying degrees of success and complications are currently being performed. This article discusses the short- and long-term gastrointestinal complications for the 4 most common bariatric surgical procedures: laparoscopic adjustable gastric banding, vertical sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch.

Laparoscopic adjustable gastric banding: efficacy and consequences over a 13-year period

BACKGROUND

Laparoscopic adjustable gastric banding (LAGB) is a common bariatric surgery. Although it is a safe and effective method of weight reduction in short term, it may result in some problems in long term. The purpose of this study was to investigate the consequences of LAGB in long term among morbid obese patients.

METHODS

In this prospective study, 80 patients underwent LAGB using pars flaccida technique from 2001 to 2006. Long-term postoperative consequences and complications of these patients were recorded.

RESULTS

The preoperative mean values of weight and body mass index were 125.5 ± 22.5 kg and 44.5 ± 6.5 kg/m(2), respectively. Over the 13-year follow-up period, 56 patients (84.8%) experienced at least one complication. The most common complications were band erosion (20 patients) and weight regains (13 patients). Fifty-one patients (78.5%) required reoperation. The band of 48 patients (72.7%) was removed; of these, twenty patients (30.3%) underwent other bariatric surgeries. Percent of excess weight loss was 47.1% ± 30.1%, and the success rate was 48.7%.

CONCLUSIONS

LAGB is a successful method with low complications in short term; however, over long term, it results in various complications.

Simultaneous Gastric and Duodenal Erosions due to Adjustable Gastric Banding for Morbid Obesity

Erosion is an uncommon but feared late complication of adjustable gastric banding for morbid obesity. A high index of clinical suspicion is required, since symptoms are usually vague and nonspecific. Diagnosis is confirmed on upper gastrointestinal endoscopy and band removal is the mainstay of treatment, with band revision or conversion to other bariatric modalities at a later stage. Duodenal erosion is a much rarer complication, caused by the connection tubing of the band. We present our experience with a case of simultaneous gastric and duodenal erosions, managed by laparoscopic explantation of the band, primary suture repair of the duodenum, and omentopexy.

Implications for the NHS of inward and outward medical tourism: a policy and economic analysis using literature review and mixed-methods approaches

Background

The study examined the implications of inward and outward flows of private patients for the NHS across a range of specialties and services.

Objectives

To generate a comprehensive documentary review; to better understand information, marketing and advertising practices; examine the magnitude and economic and health-related consequences of travel; understand decision-making frames and assessments of risk; understand treatment experience; elicit the perspectives of key stakeholder groups; and map out medical tourism development within the UK.

Design and participants

The study integrated policy analysis, desk-based work, economic analysis to estimate preliminary costs, savings and NHS revenue, and treatment case studies. The case studies involved synthesising data sources around bariatric, fertility, cosmetic, dental and diaspora examples. Overall, we drew on a mixed-methods approach of qualitative and quantitative data collection. The study was underpinned by a systematic overview and a legal and policy review. In-depth interviews were carried out with those representing professional associations, those with clinical interests and representative bodies (n = 16); businesses and employees within medical tourism (n = 18); NHS managers (n = 23); and overseas providers. We spoke to outward medical travellers (46 people across four treatment case studies: bariatric, fertility, dental and cosmetic) and also 31 individuals from UK-resident Somali and Gujarati populations.

Results

The study found that the past decade has seen an increase in both inward and outward medical travel. Europe is both a key source of travellers to the UK and a destination for UK residents who travel for medical treatment. Inward travel often involves either expatriates or people from nations with historic ties to the UK. The economic implications of medical tourism for the NHS are not uniform. The medical tourism industry is almost entirely unregulated and this has potential risks for those travelling out of the UK. Existing information regarding medical tourism is variable and there is no authoritative and trustworthy single source of information. Those who travel for treatment are a heterogeneous group, with people of all ages spread across a range of sociodemographic groups. Medical tourists do not appear to inform their decision-making with hard information and consequently often do not consider all risks. They make use of extensive informal networks such as treatment-based or cultural groups. Motivations to travel are in line with the findings of other studies. Notably, cost is never a sole motivator and often not the primary motivation for seeking treatment abroad.

Limitations

One major limitation of the study was the abandonment of a survey of medical tourists. We sought to avoid an extremely small survey, which offers no real insight. Instead we redirected our resources to a deeper analysis of qualitative interviews, which proved remarkably fruitful. In a similar vein, the economic analysis proved more difficult and time consuming than anticipated. Data were incomplete and this inhibited the modelling of some important elements.

Conclusions

In 2010 at least 63,000 residents of the UK travelled abroad for medical treatment and at least 52,000 residents of foreign countries travelled to the UK for treatment. Inward referral and flows of international patients are shaped by clinical networks and longstanding relationships that are fostered between clinicians within sender countries and their NHS counterparts. Our research demonstrated a range of different models that providers market and by which patients travel to receive treatment. There are clearly legal uncertainties at the interface of these and clinical provision. Patients are now travelling to further or ‘new’ markets in medical tourism. Future research should: seek to better understand the medium- and long-term health and social outcomes of treatment for those who travel from the UK for medical treatment; generate more robust data that better capture the size and flows of medical travel; seek to better understand inward flows of medical travellers; gather a greater level of information on patients, including their origins, procedures and outcomes, to allow for the development of better economic costing; explore further the issues of clinical relationships and networks; and consider the importance of the NHS brand.

Single incision laparoscopic adjustable gastric band: technique, feasibility, safety and learning curve

INTRODUCTION

Single incision laparoscopic surgery (SILS) is established in many procedures but not in bariatric surgery. One explanation may be that SILS is technically demanding in morbidly obese patients. This report describes our technique and experience with single incision laparoscopic adjustable gastric banding (SILAGB).

METHODS

Prospective data collection was performed on consecutive obese patients who underwent SILAGB between November 2009 and February 2011. A single 3 cm transverse incision in the right upper quadrant was used for a Covidien SILS™ multichannel access port. The technique is described with a standard pars flaccida approach and the 'tips and tricks' needed for a wide range of candidates using standard laparoscopic equipment.

RESULTS

A total of 29 patients (27 female) with a median body mass index of 41 kg/m(2) (range: 35-52 kg/m(2)) and median age of 44 years (range: 22-57 years) underwent SILAGB. There were no 'conversions' to a standard laparoscopic technique. Two cases required the addition of one single 5 mm port. The only complications were two postoperative wound infections (one with a port site infection requiring replacement of the port) and one faulty band requiring replacement. There were therefore two returns to theatre and no 30-day deaths. All patients were discharged on the first postoperative day. In this series, operative times reduced significantly to be comparable with the conventional laparoscopic approach.

CONCLUSIONS

SILAGB is safe and feasible in the morbidly obese. Proficiency in this technique using conventional laparoscopic equipment can be achieved with a short learning curve.

Visceral blood flow modulation: potential therapy for morbid obesity

We present this preliminary investigation into the safety and feasibility of endovascular therapy for morbid obesity in a swine model. A flow-limiting, balloon-expandable covered stent was placed in the superior mesenteric artery of three Yorkshire swine after femoral arterial cutdown. The pigs were monitored for between 15 and 51 days after the procedure and then killed, with weights obtained at 2-week increments. In the two pigs in which the stent was flow limiting, a reduced rate of weight gain (0.42 and 0.53 kg/day) was observed relative to the third pig (0.69 kg/day), associated with temporary food aversion and signs of mesenteric ischemia in one pig.

Emotional eating: a virtually untreated risk factor for outcome following bariatric surgery

Empirical investigations implicate emotional eating (EE) in dysfunctional eating behavior such as uncontrolled overeating and insufficient weight loss following bariatric surgery. They demonstrate that EE may be a conscious or reflexive behavior motivated by multiple negative emotions and/or feelings of distress about loss-of-control eating. EE, however, has not been targeted in pre- or postoperative interventions or examined as an explanatory construct for failed treatment of dysfunctional eating. Three cases suggest that cognitive behavioral treatment (CBT) might alleviate EE. One describes treatment for distress provoked by loss-of-control eating. The first of two others, associated with negative emotions/life situations, link treatment of a super-super-preoperative obese individual's reflexive EE with 52% excess BMI (body mass index) loss maintained for the past year, 64 months after surgery. The second relates treatment of conscious/reflexive EE with 84.52% excess BMI loss 53 months after surgery. Implications for research and treatment are discussed.
