Experimental antireflux intestinal valve

The American Journal of Surgery, 1981
A reflux-preventing valve was obtained by invaginating a 3.5 to 4.5 cm segment of small bowel into the distal lumen, after removing the seromuscular layers at both ends of the segment of bowel. Antiperistaltic pressure resistance, measured at regular intervals during 6 months, showed valves with competence equal or superior to the ileocecal valve.

The evolution of a valved hepatoduodenal intestinal conduit

Journal of Pediatric Surgery, 1981
Ascending cholangitis remains among the most serious complications following operations for biliary disorders. The bacterial count of refluxing intestinal contents can be reduced by using an enteric conduit from the biliary tract to the relatively sterile duodenum.

Manometric Evaluation of an Artificial Intestinal Valve

Archives of Surgery, 1976
A new type of intestinal valve was constructed by telescoping the proximal portion of the intestin into the distal portion. The length of telescoped intestine was expressed in relation to its diameter. Various lengths of intestine were tested in 29 dogs.

Intestinal valve formation with a simple invagination technique

The American Journal of Surgery, 1984
In 17 fully conditioned mongrel dogs, the small intestine approximately 50 cm proximal to the ileocecal valve was divided. Three centimeters of the proximal bowel was then inserted into the distal bowel and anastomosis was performed using interrupted 3-0 Dexon sutures in the seromuscular layer of the proximal end and through the entire thickness of the

The Oesophago-Intestinal Valve and the Intestine in Tylenchids (Nematoda)

Nematologica, 1992
In the few tylenchids in which the oesophago-intestinal valve structure has been elucidated it consists of two cells; in all cases the actual valve is only a few micrometers long. As in the Rhabditida, the intestine in tylenchids consists essentially of two rows (one dorsal, one ventral) of a few elongated cells.

Intestinal Obstruction in the Newborn Due to a Sigmoid Colon Valve

Archives of Surgery, 1958
Intestinal obstruction in the neonatal period secondary to the congenital anomalies of malrotation, peritoneal bands, atresias, stenoses, reduplications, and meconium ileus are well-recognized clinical entities which have been lucidly and precisely described and reported in the surgical literature and standard textbooks.

A technique for preservation of the ileocecal valve in the neonatal short intestine

Journal of Pediatric Surgery, 1989
We report a technique, appendiceal interposition, which permitted preservation of the ileocecal valve in an infant with a congenitally short intestine (jejunum, 12 cm; ileum, 1 cm). The procedure was performed on the first day of life in conjunction with jejunal lengthening by the Bianchi technique.

Role of enteric plexuses in the competency of telescoped intestinal valves

The American Journal of Surgery, 1987
The mechanism of preventing intestinal regurgitation by means of a telescoped intestinal valve has been investigated in this study. Ten telescoped intestinal valves were uniformly created in dogs. A tolerance test to barium reflux was performed before the animals were sacrificed 16 weeks postoperatively, which yielded various barium tolerance values ...

The Value of Intestinal Valves in Urinary Diversion — an Experimental Study

British Journal of Urology, 1975
Summary It has been shown in experimental animals that an ileorectal valve incorporated into the operation of uretero‐ileosigmoidostomy cannot be relied upon to prevent ascending urinary tract infection. However, a colorectal valve, not previously described, has been effective in preventing the development of a ...

Inclusion of Donor Colon and Ileocecal Valve in Intestinal Transplantation

Transplantation, 2008
Evaluation of the clinical impact of including donor colon and ileocecal valve in patients receiving primary intestinal transplantation has not been performed in a sufficiently large series of cases.Cox stepwise regression of overall and cause-specific graft survival was performed to evaluate the clinical impact of including donor colon in our single ...
