[Upper gastrointestinal haemorrhage after venous bypass in cirrhotics (author's transl)].

In a series of 76 patients who had undergone venous bypass for upper gastrointestinal haemorrhage, the authors noted 13 recurrences of bleeding, six resulting in death directly or secondary to hepatic failure. Repeated rupture of esophageal varices after thrombosis of an anastomosis is well known but in one out of two cases a second bypass involving another part of the portal territory resulted in cure. The important problem remains that of the precise aetiological diagnosis of the haemorrhage, there often being a doubt between esophageal varices and haemorrhagic gastritis.

[Pancreatic reflux into Wirsung's duct during peroperative biliary radiomanometry in acute and chronic pancreatitis (author's transl)].

Pancreatic reflux during radiomanometry is more frequent during acute and chronic pancreatitis. In acute pancreatitis, it is due in 1 case out of 3, to distal obstruction which must be overcome very rapidly. There is no prognostic significance.

[Reflux into the pancreatic duct during peroperative biliary radiomanometry. Report of 200 cases (author's transl)].

The authors have observed 200 cases of reflux into the pancreatic duct out of 2,500 biliary operations with radiomanometry. Out of the 200 cases, 109 were functional, i.e.

[Stenosing odditis: diagnosis and treatment. Report of 109 cases (author's transl)].

Stenosing odditis represents only 4.5 p. cent of all benign lesions of the extrahepatic bile ducts.

[Surgical treatment of acute hemorrhagic pancreatitis. Report of 75 cases. (author's transl)].

Out of 75 definite cases of acute hemorrhagic pancreatitis, 39 were associated with a biliary lesion of which 16 were definitively the cause of the pancreatitis (11 embedded gall stones = 1/5th of the gall stones embedded in the ampulla of Vater and producing acute hemorrhagic pancreatitis). The biliary pancreatites were twice as severe as the primary pancreatites. This justifies the emergency exploration of the bile duct in any case of severe pancreatitis, suggesting acute hemorrhagic pancreatitis.

[Surgical treatment of villous tumors of the rectum].

Out of 36 villous tumours observed in 31 patients, 50 p. 100 were sessile and 1/3rd were degenerated, their degeneration was much more frequent in the case of sessile villous tumours. There were 5 biopsy errors.

[Colo-anal invaginations in adults].

Colo-anal intussusception is exceptional, there are only 6 published cases including ours, intussusception of the colon into the rectum is rare. It raises numerous diagnostic and surgical problems. The cause is always a tumour, usually malignant.
