Push enteroscopy.

Abstract

Push enteroscopy has superseded sonde enteroscopy principally because of its ability to provide therapy, as well as diagnosis. An overtube limits gastric looping and allows deeper jejunal insertion. A working channel allows therapeutic intervention. The technique is increasingly used to the diagnosis and treatment of small intestinal disorders, particularly in obscure gastrointestinal bleeding. The wider acceptance of push enteroscopy into routing practice requires further clinical effectiveness data.

Laparoscopic surgery of the gastroesophageal junction.

Incompetence of the lower esophageal sphincter mechanism leads to gastroesophageal reflux (GER), which is the most common indication for surgery of the gastroesophageal junction. Evaluation, diagnosis, and the modern surgical treatment of GER are discussed. Evaluation of patients with severe heartburn include upper endoscopy to evaluate the general condition of the esophagus, stomach, and duodenum; an upper gastrointestinal contrast study for a complete anatomic view of the esophagus and stomach; esophageal manometry to evaluate the function of the esophagus; 24-hour pH monitoring to determine esophageal acid exposure; and a gastric emptying study selectively to determine the presence of a motility disorder. These studies most often prove the diagnosis of gastroesophageal reflux, hiatal hernia, Barrett's esophagus, peptic esophageal stricture, paraesophageal hernia, or achalasia. The laparoscopic approach to treatments for these include Nissen fundoplication, Toupet fundoplication, Collis gastroplasty with fundoplication, modified Heller myotomy, esophageal diverticulectomy, and revisional operations. These procedures are described in detail. The results of these operations indicate that they are safe and effective and should be considered the new gold standard for correction of gastroesophageal pathology. Laparoscopic surgery has revolutionized many procedures traditionally performed through a laparotomy. Although they are technically more difficult and require a significant amount of time and practice for the surgeon to become proficient, it is becoming apparent that for functional surgery of the gastroesophageal junction laparoscopy is the access of choice.

Evaluation of endoscopic injection sclerotherapy with and without simultaneous ligation for the treatment of esophageal varices.

For more effective and simple endoscopic injection sclerotherapy (EIS) for esophageal varices, we developed an EIS procedure with ligation (EISL) that is non-invasive, in which EIS and endoscopic variceal ligation (EVL) are performed simultaneously. In this study, we compared EISL and EIS in a randomized sample of patients (n = 14 for each procedure). For EISL, EVL was performed, including the injection site, after the injection of 5% ethanolamine oleate with iopamidol (EOI) into a varix. The mean number of treatment sessions required for eradication of esophageal varices was 2.3+/-0.5 for EISL and 3.9+/-0.8 for EIS (P < 0.001); the mean number of treatment sites was 6.2+/-2.2 for EISL and 14.0+/-5.0 for EIS (P < 0.001); the mean total amount of EOI used was 13.8+/-5.2ml for EISL and 26.3+/-9.8ml for EIS (P < 0.001). There were no significant differences in rates of recurrence of varices or in bleeding between the two groups. For EISL, fewer treatment sessions and less sclerosant were sufficient, probably because the sclerosants were more effective due to the blockage of variceal blood flow by the ligation. This method should provide a novel modification of EIS.
