The physiology and pathophysiology of the sphincter of Oddi are poorly understood. The relationships of functional disorders of the sphincter to biliary and pancreatic disease and of organic lesions of the papilla to pancreatic inflammatory disease are subjudice to say the least. The efficacy of sphincter section in the treatment of chronic pancreatitis is unproved. Section of the sphincter may be necessary to treat biliary tract pathology but its use should not be routine or indiscriminative since, there is morbidity as well as mortality. Finally, the price of sphincterotomy is: 1. hemorrhage; 2. duodenal perforation; 3. pancreatic duct damage--a. acute pancreatitis; b. chronic pancreatitis; 4. sphincter incompetence--a. common duct regurgitation--cholangitis; b. pancreatic duct regurgitation--pancreatitis; 5. sphincter stenosis--obstructive jaundice; 6. stasis cholecystitis; 7. diarrhea; 8. morbidity 10%; 9. mortality 1.9%.

The absorption of bile acids from the human large bowel was studied in eight patients. All patients had cholecystitis and cholelithiasis and had to undergo cholecystectomy. Cholic acid-(14)C was injected during surgery into the lumen of the cecum, hepatic flexure of the colon, or transverse colon in six patients, under the visual control of the surgeon. Common duct bile was collected by T tube daily for 5 days, and bile acids were extracted. Significant amounts of radioactivity appeared in T tube bile in each patient. T tube bile acids contained a total of 43.6-84.6% of the administered radioactivity; the average for the six patients was 58.9%. The majority of the tracer was excreted during the first 24 hr. In an additional patient cholic acid-(14)C was given in the form of an enema 5 days postoperatively. In this subject 30.8% of the retained radioactivity was excreted through the T-tube in 48 hr. The labeled cholic acid was recovered as both cholic and deoxycholic acid from T tube bile. Thin-layer chromatographic analysis of the bile acid samples indicated that the fraction of radioactivity recovered as deoxycholate increased with time during the postoperative period. Gas-liquid chromatographic analysis showed that the daily total quantity of excreted bile acids increased significantly from the 1st-5th days of the experiment. The amount of cholate excreted in T tube bile increased markedly with time, that of chenodeoxycholate increased moderately, and that of deoxycholate decreased sharply during the 5 days of the experiment. In three patients, injection of radiopaque material mixed with the tracer showed no evidence of regurgitation into the small bowel by serial X-rays. In an additional patient, tube aspirate from the terminal ileum contained no radioactivity. The results indicate that cholic acid is converted to deoxycholic acid in the human colon, and both of these bile acids are absorbed from the human large bowel in significant amounts. These data establish the previously unproved concept that significant absorption of bile acids takes place from the large bowel of man.

Mucus secretion is increased by various causative agents of inflammation in the mucosa. Although mucus production of the choledochal epithelial cells (except goblet cells) has never been noted in the rat in normal physiological conditions, it is seen as an inflammatory reaction in animals with choledochoenterostomy, which brings bacteria and active digestive enzymes into the common bile duct through regurgitation of intestinal contents. It is known that stagnant bile alone can cause inflammation in the mucosa of the gallbladder in patients with aseptic acalculous cholecystitis. In this study, aseptic bile stagnation was caused by choledochal dilation made by detaching the common bile duct from the hepatoduodenal ligament in five rats, and histological changes of the choledochal epithelium were observed by light and transmission electron microscopy 17 months after the operative procedure to determine whether stagnant bile could cause mucus production in choledochal epithelial cells. Mucus production was noted in two rats by light microscopy and in all the rats by transmission electron microscopy, and so it was demonstrated that stagnant bile could give rise to this phenomenon in the rat choledochal epithelium.
