On retro-peritoneal hernia : being the 'Arris and Gale' lectures on the 'The anatomy and surgery of the peritoneal fossae' : delivered at the Royal College of Surgeons of England in 1897. by the aorta, which projects into the cavity of thefossa; and laterally by two serous folds—the duodcno-pavictalfolds. These are triangular, having a base looking downward,a duodenal border which is attached on each side to theposterior surface of the duodenum, and a parietal borderwhich is blended with the posterior parietal peritoneum ateach side of the aorta. At the line of fusion of the leftligament there lies the inferior mesenteric vein. The depthof the fossa varies from 7 to 9 centimetres. Such are the fossse found in the duodenal region. Certain THE FOLDS AND 33 of them are found existing alone. The duodenojejunal, theinfra-duodenal, and the fossa of Brosike are never found inconjunction with other of the fossas. The fossa of Landzert,the para-duodenal fossa, on the contrary, is practically alwaysfound only when other fossae are present, and, as has beenpreviously mentioned, its complications are almost as frequentas its normal condition. The most common union that it.

The fossae have been described in what is considered to betheir normal and characteristic forms. It is important toremember that the fossae and their folds are capable ofconsiderable alteration. Not infrequently remnants of anold peritonitis are found, but all such cases have been leftentirely out of consideration. Plastic adhesions so formed 3 34 THE DUODENAL FOLDS AND FOSSA? give rise to innumerable folds and fossae.
