Intragastric Balloon (BIB System) in the Treatment of Obesity and Preparation of Patients for Surgery - Own Experience and Literature Review

UNLABELLED Despite the recognition of bariatric surgery as the only effective method of weight reduction, we remain in search of minimally invasive methods, both for the treatment of obesity and preparation of patients for surgical procedures. The aim of the study was to determine intragastric balloon (Allergan) implantation results as the only method of treating obesity, and patient preparation for further stages of abdominal hernia operations, as well as other surgical procedures. MATERIAL AND METHODS The study presented own results considering the use of Bioenteric Intragastric Balloons (BIB system) in the treatment of pathological obesity, and preparation of patients for bariatric surgery and abdominal hernia operations. The study group comprised 18 female and 7 male patients. Average patient age amounted to 50.6 and 54 years, respectively. Indications for intragastric balloon insertion were as follows: preparation for hernia (10 cases) and bariatric (5 patients) operations, and weight reduction management (8 patients). In two cases the implantation of the intragastric balloon served the preparation for gynecological and orthopedic (vertebral column) operations. One female patient was prepared for both bariatric and hernial surgery. The procedure was performed under general anesthesia. Statistical analysis considered 22 patients (one female patient was excluded from analysis, due to death, two other were excluded because of lack of sufficient data).Results. In case of two patients the intragastric balloon system was removed before 6 months had elapsed because of intolerance. One female patient died during the observation period for reasons not related to the procedure. The obtained BMI reduction ranged between 2 and 6 kg/m2, which amounted to a maximum weight loss of 24 kg. In one patient a weight gain of 2 kg was observed. Considering patients prepared for abdominal hernia operations weight reduction was greater and better maintained after the removal of the BIB system. CONCLUSIONS According to the authors of the presented study the intragastric balloon serves its role as a bridge to bariatric procedures and weight reduction, before planned extensive postoperative hernia operations. The use of the intragastric balloon only to reduce weight has no medical and economic justification.

Role of saliva in esophageal defense: implications in patients with nonerosive reflux disease.

Background:It has been previously demonstrated that patients with reflux esophagitis exhibit a significant impairment in the secretion of salivary protective components versus controls. However, the secretion of salivary protective factors in patients with nonerosive reflux disease (NERD) is not explored. The authors therefore studied the secretion of salivary volume, pH, bicarbonate, nonbicarbonate glycoconjugate, protein, epidermal growth factor (EGF), transforming growth factor alpha (TGF-&agr;) and prostaglandin E2 in patients with NERD and compared with the corresponding values in controls (CTRL). Methods:Salivary secretion was collected during basal condition, mastication and intraesophageal mechanical (tubing, balloon) and chemical (initial saline, acid, acid/pepsin, final saline) stimulations, respectively, mimicking the natural gastroesophageal reflux. Results:Salivary volume, protein and TGF-&agr; outputs in patients with NERD were significantly higher than CTRL during intraesophageal mechanical (P < 0.05) and chemical stimulations (P < 0.05). Salivary bicarbonate was significantly higher in NERD than CTRL group during intraesophageal stimulation with both acid/pepsin (P < 0.05) and saline (P < 0.01). Salivary glycoconjugate secretion was significantly higher in the NERD group than the CTRL group during chewing (P < 0.05), mechanical (P < 0.05) and chemical stimulation (P < 0.01). Salivary EGF secretion was higher in patients with NERD during mechanical stimulation (P < 0.05). Conclusions:Patients with NERD demonstrated a significantly stronger salivary secretory response in terms of volume, bicarbonate, glycoconjugate, protein, EGF and TGF-&agr; than asymptomatic controls. This enhanced salivary esophagoprotection is potentially mediating resistance to the development of endoscopic mucosal changes by gastroesophageal reflux.

Endoscopic removal of a battery that was lodged in the oesophagus of a two-year-old boy for an extremely long time

In the present work we describe a 2-year-old boy whose battery ingestion was overlooked, and who had the battery endoscopically removed from the upper part of his oesophagus after several months. This is the only described case of such a long impaction of a lithium battery in the oesophagus, without development of severe complications. We stress the necessity to take into account ingestion of a dangerous foreign body by children demonstrating unspecific clinical signs.

A distinct salivary secretory response mediated by the esophago-salivary reflex in patients with Barrett's esophagus: Its potential pathogenetic implications

PURPOSE A significantly compromised epidermal growth factor (EGF) secretion by basal parotid saliva may contribute to the development of Barretts esophagus (BE). The rate of secretion of EGF as well as a wide spectrum of protective factors in total basal and stimulated saliva in BE patients remains to be explored. We therefore studied the rate of secretion of salivary buffers, glycoconjugate, protein, EGF, transforming growth factor α (TGFα) and prostaglandin E₂ (PGE₂), evoked by esophago-salivary reflex, in patients with BE and controls (CTRL). MATERIAL/METHODS Salivary secretion was collected during basal condition, mastication, and intraesophageal mechanical and chemical stimulations respectively, mimicking the natural gastroesophageal reflux scenario. RESULTS Salivary pH in BE was significantly lower than in controls during mechanical (p<0.001) and chemical stimulations (p<0.001). Bicarbonate and protein outputs in BE were significantly lower during mechanical (p<0.05) and chemical stimulations (p<0.01). The non-bicarbonate and glycoconjugate outputs in BE were lower during chemical stimulation (p<0.05) and during mechanical (p<0.05) and chemical stimulations (p<0.05) respectively. The rate of salivary EGF output in BE was significantly lower during mechanical stimulation (p<0.05). We observed a higher TGFα output during mastication (p<0.05) and PGE2 secretion during basal and masticatory condition (p<0.05) in BE. CONCLUSIONS Patients with BE demonstrated significantly compromised salivary pH and rate of secretion of bicarbonate, non-bicarbonate, glycoconjugate, protein and EGF. This impairment could potentially predispose to the development of accelerated esophageal mucosal injury. Potential restoration of this impairment by masticatory stimulation of salivary secretion using sugarless chewing gum justifies further clinical exploration.
