Late subjective and objective evaluations of antireflux surgery in patients with reflux esophagitis: analysis of 215 patients.

The results of late subjective and objective evaluations of antireflux surgery in 215 patients with reflux esophagitis who were included in a prospective, controlled study are reported. A special protocol--including analysis of reflux symptoms, radiology, endoscopy, esophageal manometry, and standard acid reflux test--was designed. The surgical technique used was as follows: (1) highly selective vagotomy, (2) closure of the hiatus, (3) calibration of the cardia, (4) posterior gastropexy, and (5) fixation of the gastric fundus to the diaphragm.

Late results of a prospective randomised study comparing forceful dilatation and oesophagomyotomy in patients with achalasia.

Late results in 81 patients with achalasia treated in a prospective randomised study comparing forceful pneumatic dilatation with the Mosher bag and surgical anterior oesophagomyotomy by abdominal route, are reported. There were no deaths from either of the treatments. Two patients (5.

[Primary motor disorders of the non-achalasic esophagus: a manometric analysis].

We studied 85 patients with esophageal symptoms of a motor abnormality in whom esophagitis, achalasia or other organic lesions were ruled out by endoscopy. Main symptoms were dysphagia and severe retrosternal pain. Cardiac origin of the pain was ruled out by clinical and EKG evaluation in 72% of patients.

Late results of immediate primary end to end repair in accidental section of the common bile duct.

The late results of 43 patients with accidental section of the common bile duct are presented. Injuries located high at the hepatic duct were three times more frequent than those located more distally. A complete section occurred in 36 while incomplete section was observed in seven patients.

[Prevalence of esophageal and gastrointestinal symptoms in Chilean adults].

We surveyed 300 randomly selected presumable healthy adults for previously defined gastrointestinal and esophageal symptoms. Heartburn was the most common symptom, more frequent in females than in males (p less than 0.01).

[Clinical and laboratory correlation of severe esophagitis compared to mild or moderate esophagitis].

Between 1976-1987, 408 patients were studied for Reflux Esophagitis. Clinical, endoscopic, manometric characteristic were analyzed, and scintigraphic studies for gastroesophageal and duodenogastric reflux were done. Esophagitis was classified according endoscopic findings in Esophagitis grade I (non confluent erosion), grade II (confluent erosions), grade III ("uncomplicated Barrett syndrome") and grade IV (esophageal ulcer or stricture ("complicated Barrett syndrome").

Late subjective and objective evaluation of the results of esophagomyotomy in 100 patients with achalasia of the esophagus.

One hundred patients with achalasia of the esophagus were analyzed at a late follow-up by means of subjective and objective parameters. The surgical technique consisted of an anterior esophagomyotomy (6 cm long, not extending into the stomach more than 5 to 10 mm) with the addition of an anterior hemi-Nissen or Dor procedure, similar to the Thal serosal patch. No operative deaths occurred.

Triglyceride and cholesterol content in bile, blood, and gallbladder wall.

Cholesterol gallstone disease is frequent in Chile compared with other countries, as is cholesterolosis of the gallbladder. The purpose of this study was to determine any differences in bile composition and cholesterol content in the gallbladder wall and serum of patients compared with findings in patients with gallstones and control subjects. In control subjects, cholesterol content of the gallbladder wall was determined in autopsy material.

Common bile duct pressure in patients with common bile duct stones with or without acute suppurative cholangitis.

Resting common bile duct pressure was measured in three groups of patients: group 1, 53 patients with gallstones but without common duct stones; group 2, 35 patients with common bile duct stones unaccompanied by cholangitis; and group 3, 36 patients with common duct stones and acute suppurative cholangitis. A significantly higher pressure in the common bile duct was documented in patients with cholangitis when compared with the other two groups. Twenty-four patients with cholangitis had common duct pressure values above 20 cm H2O, the maximal values of normal.

Anomalies of extrahepatic biliary duct and gallbladder associated with intestinal malrotation: a case report.

Knowledge of congenital anomalies in abdominal viscera is important for surgeons, if they are to treat such patients and solve their problems adequately. This article presents an unusual case of reversed rotation of the intestine associated with anomalies in the biliary tract and gallbladder. This patient underwent surgery because of a bleeding duodenal ulcer.

A prospective, randomized study comparing highly selective vagotomy and extended highly selective vagotomy in patients with duodenal ulcer.

The recurrence rate of duodenal ulcer after highly selective vagotomy is nearly 10 percent. To diminish this percentage, extended highly selective vagotomy with sectioning the gastroepiploic nerves has been proposed in order to reduce postoperative gastric acid secretion. We have prospectively compared the decrease in gastric acid secretion through measurement of basal acid output, maximal acid output, and peak acid output in patients who underwent highly selective vagotomy or extended highly selective vagotomy.

Type IV gastric ulcer: a new hypothesis.

In 1965 Johnson proposed his classification for gastric ulcer, which was subsequently adopted by the majority of surgeons. However, for many years we have observed the high frequency of subcardial or juxtacardial ulcers near the esophagogastric junction, which has not been reported elsewhere. In this article we describe the characteristics of this type of gastric ulcer and propose to designate it as a type IV gastric ulcer.

A prospective study of intraoperative histologic antrum and corpus boundary in patients undergoing highly selective vagotomy for duodenal ulcer.

The results of the present study demonstrate that, at the level of the proximal branch of Crow's foot of Latarjet, parietal cells are found, and therefore, it must be sectioned when performing highly selective vagotomy. At the level of the distal branch, antral mucosa is found. At the level of the middle branch, in almost one-half of the instances, parietal cells are found, and its section must be evaluated with gastric emptying studies.
