Treatment of congenital dilatation of the choledochus- reconstruction of the bile duct after resection of the dilated choledochus.

Reconstruction of the way of bile flow was attempted in 21 cases with the resection of the dilated bile duct, and the post-operative courses were observed over a long period. It was found that ascending cholangitis is seldom caused by the hepaticoduodenostomy. It is important, when hepaticoduodenostomy is performed, that the sound section of the wall of the bile duct without stenosis in the hepatic side should be selected. Reconstruction of the way of the bile flow to prevent ascending cholangitis by leading normal bile flow into the duodenum should be devised.

Gastroplasty with reinforced greater curve stoma for morbid obesity.

Forty-four morbidly obese patients underwent gastroplasty with a transverse double stapled partition forming a 20-30 ml proximal gastric pouch and a 10 mm diameter stoma on the greater curve supported by three non-absorbable imbricating seromuscular inverting suture layers to form a neopylorus. All patients have been followed at approximately 4 weekly intervals for at least 72 weeks and all patients have been submitted to endoscopic assessment at the end of 1 year. There was no mortality and there were no major immediate postoperative complications. Three patients (6.8%) had inadequate weight loss (in two associated with partial staple line failure). The other 41 patients (93.2%) reached final weights less than or equal to 40% above ideal weight. Sixteen patients (36.4%) reached their ideal weight. Six patients (13.6%) developed stomal stenosis (two requiring re-operation, and four requiring endoscopic dilatation).

Endoscopic dilation of benign esophageal strictures: report on 1043 procedures.

OBJECTIVE: Endoscopic dilation is considered the best treatment for most cases of benign esophageal stricture, although the best dilation technique and the kind of stricture is the most amenable to treatment is still controversial. We report on our experience on a large series of patients treated by dilation without the aid of fluoroscopy and compare the results of this therapy among patients with strictures from different causes. METHODS: Between 1992 and 1997, we performed 1043 dilation sessions on 153 patients. Treatment was considered adequate if the esophageal lumen could be dilated up to the size of a 42F catheter. If the stricture recurred after initial successful treatment, the stricture was dilated again up to a 42F catheter. RESULTS: One hundred forty patients (96 men, 44 women; mean age, 54.1 yr) were followed-up for a mean of 20.5 months (4 to 62 months). Stricture's etiology was postsurgical in 80 patients, peptic in 37, caustic in 12, and from other causes in 11 patients. Adequate dilation was achieved in 93.5% of the patients (131 of 140). Patients with peptic strictures needed a median of three sessions to be adequately dilated during follow-up in comparison to five sessions among patients with postsurgical or caustic strictures (p = 0.07). There were four perforations, with one death (2.8% and 0.7% per patient and 0.4% and 0.1% per session, respectively). CONCLUSIONS: Endoscopic dilation without the aid of fluoroscopy is safe and effective in relieving dysphagia caused by benign strictures of different causes, although repeated sessions are necessary because of stricture recurrence.

Risk factors for gastric dilatation in Irish setter dogs.

Questionnaires were used to obtain data about Irish setters with gastric dilatation (GD) and control Irish setters. The risk of GD increased with age (P < 0.01) but was not associated with gender. Age and gender-matched controls were compared with cases (n = 74). Predisposing risks were aerophagia (unadjusted odds ratio 12.44, P < 0.001), a single food type (adjusted odds ratio 3.15, P < 0.01) and feeding once daily (adjusted odds ratio 2.90, P < 0.02). Apparent risk from a dry food diet and a condition score of less than 2 was not confirmed by logistic regression. Precipitating risks were recent kennelling (unadjusted odds ratio 100, P < 0.005) or a car journey (unadjusted odds ratio 3.29, P < 0.025). No risk was attributed to intensity or duration of exercise, temperament, appetite, speed of eating, vomiting or diarrhoea.

Balloon dilatation of alimentary tract strictures.

From a series of balloon dilatations of alimentary tract strictures 11 patients with different types of gastric and oesophagogastric anastomotic stenoses are reported. The dilatation of gastric outflow tract obstructions was highly effective in the treatment of retention. In 7 out of 8 cases with gastric outflow stenosis surgery could be entirely avoided and replaced by balloon dilatation. The importance of eliminating retention in the healing of gastric ulcer is discussed. Fistulation in oesophagogastric anastomoses due to stenosis of the outflow portion was successfully treated. The importance of achieving a free outflow tract in order to prevent insufficiency of the anastomosis and formation of a fistula is stressed.

Plain film diagnosis in intussusception.

In early childhood intussusception a characteristic gas pattern is often visible on plain radiographs which can be used for diagnosis. To test this hypothesis, radiographs of 163 children with intussusception, and as many controls, were reviewed. By using multivariable analysis, it appeared that five out of seven parameters (reduced amount of gas in the jejunum; lateralization of the ileum; indiscernible caecum; reduced amount of feces in the colon; and visibility of the intussusceptum) had discriminatory value. For each parameter a weighting (in points) was derived and the patients were classified: the higher the score the more likely that an intussusception was present. A sensitivity of 90% and a specificity of 90% were obtained.

Studies On Intestinal Trematodes In Korea: VI. On The Metacercaria And The Second Intermediate Host Of Fibricola Seoulensis.

This study was carried out to confirm the infection source of the human case of Fibricola seoulensis, and to reveal out a part of its life cycle in Korea. Also the morphological characteristics of the metacercaria were described. The results were summarized as follows: 1. Rana nigromaculata and Natrix tigrina lateralis were found to be infected naturally by the metacercariae(diplostomula) of F. seoulensis. The metacercarial capsule was round to elliptical in tissue of the intermediate hosts with a long diameter 0.232~0.385 mm. Liberated metacercariae were ovoid with small conical posterior body. Body length measured 0.199~0.312 mm and width 0.153~0.252 mm. 2. The infection rate of R. nigromaculata by the metacercariae ranged from 87% to 100% by area, and the number of the larvae ranged from 3 to 390 by frog. The metacercariae were found in skeletal muscle of frogs, from head to hindlegs. 3. All examined N. t. lateralis were found to be infected by the metacercariae with the range of numbers frome 3 to 35,918. The larvae were collected from all viscera and body segments except for the head of the snakes. However, a great majority of the metacercariae were collected from the stomach. 4. Hematoxylin-eosin stained preparations of frog skeletal muscle and snakes stomach revealed that the metacercariae had no cyst wall of worm origin, but encapsulated by the host tissue. Some of them were found in dilated lymphatic vessels. The larval infection was associated with slight or severe inflammatory reaction even with granuloma formation. By above results, it was concluded that the frog, Rana nigromaculata, was the second intermediate host, and the snake Natrix tigrina lateralis was a paratenic host of F. seoulensis in nature in Korea.

Cardiopulmonary measurements in dogs undergoing gastropexy without gastrectomy for correction of gastric dilatation-volvulus.

OBJECTIVE: To measure cardiopulmonary variables, including cardiac index, in dogs with naturally acquired gastric dilatation-volvulus (GDV). DESIGN: Prospective clinical study. ANIMALS: 6 dogs with GDV. PROCEDURE: In addition to typical medical and surgical management of GDV, the dorsal metatarsal and pulmonary arteries and right atrium of the dogs were catheterized to obtain cardiopulmonary measurements before and during anesthesia and surgery. RESULTS: All dogs underwent gastropexy but none required gastrectomy. Mean cardiac index and mean arterial blood pressure for this small population of dogs with GDV were not significantly different from those reported for clinically normal awake or anesthetized dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Dogs with naturally acquired GDV without gastric necrosis may not have the classic characteristics, including decreased cardiac index and hypotension, of hypovolemic circulatory shock.

Acid-base and electrolyte values in dogs with acute gastric dilatation-volvulus.

Twenty dogs with acute gastric dilatation-volvulus (GDV) and 37 clinically normal dogs had arterial blood drawn for analysis of pH and blood gases. There was no statistically significant difference between values from the 2 groups. By calculation of the anion gap and by assessing arterial bicarbonate concentration, it appeared there were concomitant and offsetting factors, resulting in normal values for pH, blood gases, and anion gap in dogs with GDV. The results obtained indicated that sodium bicarbonate therapy should not be used in dogs with GDV.

Corrosive injury to the upper gastrointestinal tract.

Corrosive injury to the UGI tract is a common problem and has a wide spectrum of presentations. Unlike in the West, where lye ingestion is more frequent, corrosive injury in India is more commonly due to acids. Depth of the injury is the most important factor which determines the outcome. Endoscopy done soon after corrosive ingestion is safe and is very helpful in assessing the extent and severity of injury and in planning proper management of these patients. At present no therapy has been proven to be effective for prevention of stricture formation. Endoscopic dilatation seems to be the treatment of choice for management of most esophageal strictures with very good short and long term results. Surgery should be considered only when dilatation fails.

[The ultrastructure of the main exocrinocytes in the glands proper of the gastric mucosa in A avitaminosis].

The electron microscopic and morphometrical methods were used to study the ultrastructural organization of main exocrinocytes of the proper glands of the mucous membrane of the stomach of rats under conditions of A-avitaminosis. Deficiency of vitamin A causes dystrophic alterations of main exocrinocytes. The fragmentation, degranulation and considerable dilatation of cisterns of the granular endoplasmic reticulum, destruction of the Golgi complex membranes, disturbance of the membranous organization of secretory vacuoles were observed. A conclusion is made of disturbances of the protein-synthesizing function of main exocrinocytes under conditions of A-avitaminosis.
