[Primary intestinal lymphangiectasis or Waldmann's disease (author's transl)].

The authors report the observation of a primary intestinal lymphangiectasy diagnosed on a young girl sent for isolated edema of her inferior members, recently appeared. Clinical examination was normal. Biology found a low protein rate at 33 g/l and a low lymph rate : 183 L/mm3. Hepatic and renal records were normal. Test to marked albumin asserted the exsudative enteropathy with a fecal radio-activity of 3.6% (N 1%). Biopsy of the small intestines set out lymphangiectasies of the intestinal mucosa. Referring to this observation and to literature date, the authors realise a clinical and physiopathological analysis of Waldmann's disease or primary intestinal lymphangiectasy.

[Obstruction of the extrahepatic bile ducts by tumor debris and/or clots in primary cancer of the liver. Diagnostic and therapeutic problems. Apropos of 9 personal cases and review of the literature].

The onset of jaundice in patients with primary liver cancer is sometimes caused by intra ductal biliary system tumor casts, free floating debris or hemobilia. The diagnosis of this complication is now possible by E.R.C.P. or P.T.C. We report 9 cases of unrecognized primary liver tumor revealed by intra biliary system migration of tumor casts or free floating debris. In three patients the diagnosis was operative, but for the last six cases the E.R.C.P. data in addition with U.S., C.A.T. Scan and/or hepatic angiography were helpful in determining the nature of the hepatic and biliary changes, the operability (size, location, extent). A curative surgery was not indicated in our 8 operated patients: liver resection and biliary decompression. With the palliative procedures, bilio enteric by pass (2 cases) T tube (1 case) trans hepatic uni or bilateral tubes. The survey was not longer than 11 months. Three patients died in post operative course. Only 56 patients among 117 observations of the literature have been operated: 10 liver resections including the main hepatic junction in two cases were performed with one hospital death, two patients were alive over 2 years with recurrence and three patients were disease free with a follow up less than one year. The operative mortality with palliative procedures was 34.4%; the one-two years survival was 23%; the two longest survivors lived 41 and 61 months.

[Assay of serum elastase 1 in adenocarcinoma of the pancreas: diagnostic value, compared and combined study with serum CEA and CA 19-9].

Serum elastase 1, CEA and, CA 19-9 titers were determined by radioimmunoassay in 113 patients with benign non pancreatic digestive disease, 88 patients with non pancreatic carcinoma, 25 patients with chronic pancreatitis and 40 patients with pancreatic carcinoma (of whom 34 were classified according to Fortner's staging classification), respectively: a) to evaluate the diagnostic value of elastase in pancreatic carcinoma, b) to compare and to study the value of its association with CEA and CA 19-9 for earlier detection of this type of cancer. The specificity of serum elastase (greater than 500 ng/dl) was greater than that of CA 19-9 (greater than 37 U/ml), (93.3 p. 100 vs 64.6 p. 100, p less than 0.01), but its sensitivity was significantly lower than that of CA 19-9 (27.5 p. 100 vs 82.5 p. 100; p less than 0.001). The sensitivity of CA 19-9 (greater than 37 U/ml) and/or elastase (greater than 500 ng/dl) was 85.2 p. 100 (greater, but not significantly, than CA 19-9 alone) and 91.6 p. 100 in Fortner stage I or II tumors (greater, but not significantly, than Fortner stage III tumors which were at 83.6 p. 100). The specificity of the combined test was 62 p. 100, lower (but not significantly) than CA 19-9 alone. As serum CEA (greater than 5 ng/ml) alone and in association with CA 19-9 was disappointing, it might be replaced by the elastase assay. The combined CA 19-9-elastase assay coupled with morphologic investigations could represent an attractive approach for earlier detection of this cancer.

[Determination of the carcinoembryonic antigen and endoscopic sphincterectomy in papillomatosis of the bile ducts].

Two new cases of multiple biliary papillomatosis are reported. In these 2 cases, endoscopic retrograde cholangiography (CRE) was performed; the roentgen findings are described; the mucinous aspect of the bile, the important levels of biliary carcinoembryonic antigen and the intraductal biopsies after endoscopic sphincterotomy (E.S.) furnished precious aid for diagnosis; one E.S. was performed in the two cases allowing satisfactory drainage biliary; in one case, surgery and chemotherapy were associated; based on these two cases and 26 others of literature, management of the disease is discussed.
