[Total pelvic exenteration and rectal cancer. Apropos of 20 cases].

Study Aim: The report of a series of 20 patients with the aim of trying to specify the implications of pelvic exenteration for rectal cancer.

Patients And Methods: From 1986 to 1996, 20 total pelvic exenterations were performed for rectal adenocarcinoma. This retrospective study included locally extended carcinomas (n = 10), and recurrences (n = 10) after anterior resection (n = 7), and after abdominoperineal resection (n = 3).

Intermittent vascular exclusion of the liver (without vena cava clamping) during major hepatectomy.

Intermittent vascular exclusion of the liver (IVEL) combines clamping of the hepatic pedicle with clamping of the main hepatic veins without interruption of caval flow. In this retrospective study, eight cases of total IVEL and eight of partial IVEL were analysed (involving only the middle and left hepatic veins) during major hepatectomy for malignant tumours. Liver parenchyma was pathological in nine cases.

[Intra-arterial hepatic chemotherapy. Experience of 200 cases].

Objectives: This retrospective study had three aims: a) to investigate whether one catheter, whatever the number of hepatic arteries, associated with miscellaneous arterial ligations, produced the same results as the implantation of multiple catheters, b) to study the survival rate after intra-arterial chemotherapy, and c) based on a multifactorial study of prognostic factors, to define the best indications of this treatment in the future.

Methods: Two hundred catheters were surgically implanted to perform intrahepatic arterial chemotherapy in patients with multiple unresectable isolated liver tumors. The origins of these tumours were colorectal cancer in 152 cases, neuroendocrine tumour in 13 cases, hepatocellular carcinoma in 9 cases, and miscellaneous tumours in 22 cases.

[Posterior mediastinal thymus. Apropos of a case in a child].

Posterior and upper mediastinal localization of the thymus gland is uncommon in young children. Presenting symptoms and signs are very variable from incidental diagnosis to bronchopneumonial with atelectasias of the left upper Chest X-Ray and CT Scan are sufficient to make the diagnosis. Treatment of complicated forms with bronchial compression requires thoracotomy and surgical excision.
