Exploration of peritoneal cavity
Duodenojejunal junction; splenic flexure of colon
The transverse colon has been elevated. Loops of the jejunum have been pulled to the right to expose the duodenojejunal junction. Peritoneal folds and recesses often associated with the duodenojejunal flexure are not well developed in this specimen. A small inferior duodenal reces (9)extends for a short distance downward beneath a broad, thin inferior duodenal fold of peritoneum.
