Intracanal metallic obstructions that block any further treatment often prevent the clinician from achieving total cleanliness of the root canal system. For the retrieval of these obstructions, most of the methods described suggest creating and enlarging a space around the obstruction to loosen it before its retrieval. This article describes a technique that consists of mechanical abrasion of t...

Infantile pyloric stenosis is the most frequently encountered infant gastrointestinal obstruction in most general hospitals. Although the primary therapy for pyloric stenosis is surgical, it is essential to realize that pyloric stenosis is a medical and not a surgical emergency. Preoperative preparation is the primary factor contributing to the low perioperative complication rates and the neces...

In 3 infants functional intestinal obstruction, associated with a short small intestine, malrotation, and pyloric hypertrophy, was shown to be due to failure of development of the argyrophil myenteric plexus, with the absence of ongoing peristalsis. 4 infants with similar clinical features have been described previously, and there is evidence for an autosomal recessive mode of inheritance of th...

Congenital antral webs are quite rare and easily overlooked or misdiagnosed. We report the case of a five-year-old boy who presented with symptoms of gastric outlet obstruction for four years; his condition was misdiagnosed twice as pyloric ulcer. Detailed gastroscopy revealed a congenital antral web. The stricture was successfully treated with endoscopic balloon dilatation without surgery.

Introduction: Pyloric stenosis is an uncommon condition in infants characterized by abnormal thickening of the pylorus muscles stomach leading to gastric outlet obstruction. Clinically are well at birth. Then, 3 6 weeks age, present with "projectile" vomiting which can lead dehydration and weight loss. Objective: To determine frequency pyloric patient presenting persistent vomiting. Material Me...

This paper presents an investigation of the effects of experimental high intestinal obstruction in dogs, with particular emphasis on changes observable in the distribution of phosphorus in the blood. The experiments were undertaken as a part of a series of studies of phosphorus distribution in the blood of man and experimental animals in a variety of pathologic conditions. In dogs, marked chang...

Fasting serum pyridoxal was assayed by an automated microbiological system in 50 patients with endoscopically confirmed active peptic ulceration. Thirty patients had gastric ulceration, 14 had duodenal, four had pyloric canal ulceration, and two had both a gastric and a duodenal ulcer. Serum pyridoxal was below normal in 28 of the gastric ulcer group and in one of the duodenal ulcer group. No d...

The patient was a 56-year-old woman who had experienced epigastralgia and dorsal pain several times over the last 20 years. She was admitted for a diagnosis of acute cholecystitis, and severe intra- and extrahepatic bile duct dilatation with inner air density was noted. No papilla of Vater was present in the descending duodenum, and 2 small holes were present in the pyloric ring. Bile excretion...

Dogs injected with proteose recovered from the intestinal contents of animals with obstruction at different levels show no significant changes in the blood chlorides even with a fatal intoxication. After the intravenous injection of lethal and sublethal doses of Witte's peptone there is little change in the chlorides. Autolyzing liver in the abdominal cavity produces no change in the blood chlo...
