[Totally implantable venous access systems. Analysis of complications].

Unlabelled: Totally implantable central venous access devices (Port-a-Cath, PaC) allow better treatment of cancer patients, with safe administration of chemotherapeutic agents, and are well accepted by the patients. The aim of the present paper is to analyze the complications of the different implant techniques on the basis of a personal experience of 92 central venous access devices.

Material And Methods: A total of 92 PaC (Port-a-Cath, Pharmacia: Celsite Braun) have been implanted in 88 patients between August 1992 and June 1995 for cancer treatment.

[Esophago-jejuno-gastroplasty in the treatment of peptic stenosis of the esophagus].

From 1973 to 1994, 21 patients with esophageal peptic stenosis were submitted to esophago-jejuno-gastroplasty with Merendino's technique. In 14 cases peptic stenosis developed after Heller's myotomy for achalasia, associated in 3 cases with fundoplication. In 3 patients the stenosis was secondary to fundoplication.

Jejunal interposition for peptic stenosis of the esophagus following esophagomyotomy for achalasia.

Retrospective analysis of the results of esophagojejunogastrostomy in 21 patients with peptic stenosis after esophagomyotomy for achalasia is reported. All patients complained of severe dysphagia.

[Surgical treatment of hydatid cysts of the hepatic dome ruptured into the thoracic cavity].

Two cases of hydatid cyst of the hepatic dome, complicated by rupture in the thoracic cavity, are reported. The Authors stress the frequency of human hydatidosis, still high in Italy, and the severity of the above mentioned complication. Surgical treatment is also discussed.

Delayed bilateral ureteral fistula following abdominoperineal resection: a case report.

Hydatid hepatothoracic fistulas. A report of 30 cases.

A retrospective study was carried out on 30 patients with hepatothoracic transdiaphragmatic fistulas, classified as hepatopleural (5 cases), hepatopulmonary (11 cases), biliopleural (1 case) and biliobronchial (13 cases). Investigations included chest X-rays, bronchography, plain abdominal films, cholecystocholangiography, liver scanning, ultrasonography and CT scanning.
