[The value and limits of endorectal sonography in the preoperative stage classification of rectal cancer].

The article deals with the valuation of endorectal and abdominal sonography in preoperative staging of rectal carcinoma. Data processing of 40 patients suffering from tumours of the rectum examined rectoscopically, by biopsy and via sonography showed that endorectal sonography can achieve preoperative staging (T) with a sensitivity of 89%, a specificity of 100%, a positive predictive value of 89% and a negative predictive value of 100%, the overall accuracy being 81%. Identification of pararectal adenopathies can be performed with a sensitivity of 16% and a specificity of 100%. Liver metastases were determined with a sensitivity and specificity of 100%. Hence, endorectal sonography is a valuable method for preoperative staging of carcinoma of the rectum.

[Ultrasonic diagnosis of echinococcal cholangitis].

The role of sonographic examination in echinococcal cholangitis is stressed based on a clinical case. Due to perforation of the hepatic hydatid cyst into the bile ducts the clinical picture of acute cholangitis occurred, this being difficult to differentiate from that of choledochal stones. The correct diagnosis was made by sonographic examination and was confirmed intraoperatively. The importance of emergency sonographic examination in severely ill patients is stressed.

[Cystic echinococcosis of the liver--problems of ultrasound diagnosis].

The authors examined 100 patients with a total of 119 cysts of the liver. The diagnosis was subsequently confirmed via scintigraphy, radiology and laparotomy. This paper reports on a sonographic analysis of cystic echinococcosis of the liver, its sonographically demonstrable types, structures and complications and their differential diagnosis. In 58% of the cases the classical aspect of cystic echinococcosis was seen (Type A). 22.7% of the cases pointed toward a sediment within the cyst (Type B). 8.4% of the cysts were septated (Type C), whereas 6.7% had daughter cysts (Type D). However, only 4.2% of the cysts were important for differential diagnosis, since they had to be set off against other space-occupying growths on account of their solid tumorous structure.

[Acute diffuse peritonitis of a rare cause].

The authors report a rare case of acute onset of non-Hodgkin lymphoma with diffuse peritonitis due to bowel perforation of secondary jejunal involvement. The admission diagnosis in the 18-years-old male with acute abdominal pain for 4 days, guarding on physical examination and pneumoperitoneum on abdominal ultrasonography was peptic ulcus perforation. The palpable splenomegaly and cervical lymph nodes on ultrasonography examination might have raised suspicion of lymphoma. Surgical exploration revealed the peritonitis origin--jejunal perforation, proximal to a stenosing tumor, a gastric tumor and confirmed the splenomegaly. Small bowel resection--end to end anastomosis--and gastric tumor biopsies were performed. The pathological diagnosis was diffuse large B-cell non-Hodgkin lymphoma. Some therapeutic considerations on digestive tract secondary lymphoma are made.

[Hemorrhagic juxtapapillary duodenal ulcer with choledochal and Wirsung's duct stenosis and duodenojejunal fistula following biliojejunal en-Y diversion. The surgical solution].

The paper reports on the clinical observation of a patient with bulbar duodenal ulcer placed in a juxtapapillary position due to a short bile duct, complicated with choledochal and Wirsung's stenosis and, finally haemorrhage and duodenojejunal fistula favoured by a gallbladder-jejunum diversion assembly. Three major surgeries, during 17 years, were required: cholecystectomy and choledochoduodenostomy for the choledochal stenosis induced by penetrating posterior bulbar ulcer; after 8 years, choledocholithotomy and gallbladder-jejunum derivation the loop in Y, (Roux) for the choledochoduodenostomy stenosis with the local lithiasis of the CBP; after 9 years, the resection of the proximal segment of the anastomosed jejunal loop with CBP and gastric resection with ulcer exeresis, followed by restoration of the gallbladder-jejunum anastomosis, gastrojejunal anastomosis and reimplantation of Wirsung's duct in the duodenal stump for juxtapapillary duodenal ulcer complicated with haemorrhage, penetration into pancreas, perforation in the jejunal loop anastomosed preduodenally and stenosis of Wirsung's duct. The final therapeutic result is good and lasts in time. The paper discusses the duodenum-gallbladder-pancreas interrelationships in the juxtapapillary ulcers, drawing the attention on the possibility of forming a duodenojejunal fistula in the patients with gallbladder-jejunum derivations.

Nonparasitic abdominal serous cysts. A multiple case report.

A group of 35 patients with nonparasitic abdominal serous cysts is reviewed in order to investigate the diagnostic and therapeutic features of these rare conditions. In most cases the cysts were localised in the liver. Other localisations were the kidney (9 cases), the mesenteric area (2 cases), the adrenals (2 cases), the spleen and the pancreas (one case each). The clinical symptoms were essentially determinated by the size of the cysts, regardless their visceral localisation. Ultrasonography was the most efficient procedure for their detection, although this method's precision for the visceral localisation of the cysts was not entirely reliable (6 errors). The low incidence of such abnormalities as well as the absence of any relevant diagnostic elements for establishing the nonparasitic character of the cysts, favoured the confusions with nonproliferous hydatid cysts, especially in cases of solitary cysts (7 patients). The most frequently used surgical procedures were partial cystectomy (18 cases) and total cystectomy (8 cases). A personal technique based on obliteration of the cavity with the bulging wall of the cysts, was used in two patients. When choosing the surgical procedure, the size, site and number of cysts were considered. Immediate and late postoperative results were very good.
