BioEnterics Intragastric Balloon: The Italian Experience with 2,515 Patients.

BACKGROUND: The temporary use of the BioEnterics Intragastric Balloon (BIB) in morbidly obesity is increasing worldwide. The aim of this study is the evaluation of the efficacy of this device in a large population, in terms of weight loss and its influence on co-morbidities. METHODS: Data were retrospectively recruited from the data-base of the Italian Collaborative Study Group for Lap-Band and BIB (GILB). After diagnostic endoscopy, the BIB was positioned and was filled with saline (500-700 ml) and methylene blue (10 ml). Patients were discharged with diet counselling ( approximately 1000 Kcal) and medical therapy. The BIB was removed after 6 months. Positioning and removal were performed under conscious or unconscious sedation. Mortality, complications, BMI, %EWL, BMI loss and co-morbidities were evaluated. RESULTS: From May 2000 to September 2004, 2,515 patients underwent BIB (722M/1,793F; mean age 38.9+/-14.7, range 12-71; mean BMI 44.4+/-7.8 kg/m(2) ; range 28.0-79.1; and mean excess weight 59.5+/-29.8 kg, range 16-210). BIB positioning was uncomplicated in all but two cases (0.08%) with acute gastric dilation treated conservatively. Overall complication rate was 70/2,515 (2.8%). Gastric perforation occurred in 5 patients (0.19%), 4 of whom had undergone previous gastric surgery: 2 died and 2 were successfully treated by laparoscopic repair after balloon removal. 19 gastric obstructions (0.76%) presented in the first week after positioning and were successfully treated by balloon removal. Balloon rupture (n=9; 0.36%) was not prevalent within any particular period of BIB treatment, and was also treated by BIB removal. Esophagitis (n=32; 1.27%) and gastric ulcer (n=5; 0.2%) presented in patients without a history of peptic disease and were treated conservatively by drugs. Preoperative co-morbidities were diagnosed in 1,394/2,471 patients (56.4%); these resolved in 617/1,394 (44.3%), improved (less pharmacological dosage or shift to other therapies) in 625/1,394 (44.8%), and were unchanged in 152/1,394 (10.9%). After 6 months, mean BMI was 35.4+/-11.8 kg/m(2) (range 24-73) and %EWL was 33.9+/-18.7 (range 0-87). BMI loss was 4.9+/-12.7 kg/m(2) (range 0-25). CONCLUSIONS: BIB is an effective procedure with satisfactory weight loss and improvement in co-morbidities after 6 months. Previous gastric surgery is a contraindication to BIB placement.

Endoscopic approach to patients with portal hypertension: a complex diagnosis. A retrospective study based on 10 years' experience.

We analyzed the endoscopic findings in 788 patients with esophageal and gastric varices who underwent upper gastrointestinal endoscopy between 1 January 1979 and 31 December 1988. Of these, 154 patients (19.6%) had gastric varices associated in various patterns with esophageal varices. Congestive gastropathy, occurring with esophageal and gastric varices (43.4%), was the most frequent pathology detected in our patients. Esophagitis was present in 15.8% of patients, but did not correlate with variceal bleeding. Endoscopy performed at 1 day to 1 week post-hemorrhage in 313 patients accurately identified the source of bleeding in only 57.2% of patients. This figure increased to 98.2% when we performed the examination within the first 24 h of hemorrhage. In this group varices were the source of hemorrhage in 72.3% of patients while the hemorrhage came from other sources, such as erosive gastritis, duodenal and gastric ulcer in 27.6% of patients.

High-dose preoperative radiation and full-thickness local excision. A new option for patients with select cancers of the rectum.

Faced with the responsibility of treating patients with invasive distal rectal cancer who were medically unacceptable for the indicated radical surgery, a prospective study was initiated in which high dose preoperative radiation and full-thickness local excision were used. High dose preoperative radiation permitted full-thickness local excision of select cancers, which, by conventional standards, otherwise would have required radical surgery and permanent colostomy. Feasibility was measured on the basis of safety of the technique, control of the cancer, and the quality of anal sphincter function expected. Patients were selected initially because of their predicted inability to tolerate radical surgery, but indications were broadened to include those whose tumors had completely disappeared after irradiation. From 1984 to 1988, 20 patients underwent 21 operative procedures for cancers located between 0 and 7 cm from the anorectal ring. This report is concerned with the 14 patients of this group who were observed for a minimum of 24 months. High-dose preoperative radiation was administered for a total dose of 4500 cGy. Excision and repair were performed 4 to 6 weeks after completion of radiation therapy. Full-thickness disc or hemicircumferential excision was accomplished by transanal, transsphincteric, and transsacral techniques, which included, in several instances, excision of the sphincter mechanism and perineal body, and/or the vaginal wall. Full-thickness local excision after high-dose radiation therapy for rectal cancers has never been reported. Follow-up observation ranged from 24 to 48 months with a median of 31 months. Rectal reservoir function and sphincter control were good in 13 patients. Local recurrence developed in three patients (21 percent), two of whom had postradiation therapy B2 mucinous cancers. Three-year actuarial rate of local recurrence is 23 percent. One (7 percent) patient died of recurrent disease. Actuarial Kaplan-Meier survival at 3 years is 61 percent. Based on the results of this small, select patient group, high-dose radiation therapy followed by full-thickness local excision appears to be a reasonable option for patients who cannot tolerate radical surgery. This bimodal approach also may serve as an option for those who are good medical risks, but for whom sphincter preservation is at stake, and to whom radical surgery offers limited benefits.

[Percutaneous endoscopic gastrostomy (PEG)].

When gastric decompression or enteral feeding are needed for patients affected by neurological problems or neoplasias with a long life expectancy (months), PEG represents the method of choice because it has a lesser number of complications, needs a mild sedation, and has a lower cost compared to surgical techniques.
