[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. The esophagogram showed the presence of a 2 to 3 cm long stenosis in the lower esophagus with a diameter < 10 mm.

[Non-parasitic splenic cysts].

Nonparasitic cysts of the spleen are uncommon and often result from blunt abdominal trauma. Nonsurgical management of blunt splenic injuries increases the number of observations of the post-traumatic cysts. Complications (infection, rupture and hemorrhage) are lifethreatening, difficult to diagnose and require urgent surgical management.
