[Malignant duodenal fistulae of colonic origin (clinical case)].

Duodenocolonic fistulas created by invasive cancer of the colon are rarely reported in the literature and their frequency is probably underestimated. We report 4 cases together with the problems encountered and therapeutic approaches used.

Original oblique sections of the retroperitoneum: radio-anatomic basis.

The authors present oblique sections of the retroperitoneum adapted to the morphology of each patient, which affects both the liver and the organisation of the retroperitoneum. This original method involve two incidences for studying the left and right retroperitoneum separately with vertical sectional planes. The authors postulate that the orientation of the retroperitoneal viscera depends on the degree of hepatic development, so these incidences are chosen with reference to axial sections of the portal bifurcation and the middle hepatic v.

Large inferior right hepatic vein. Clinical implications.

The right middle and inferior hepatic vv. are very frequent, indeed constant, but usually of small caliber. The presence of an extra-wide right inferior hepatic v.

[Synthetic prostheses used in surgery to repair abdominal wall defects (excluding groin hernias). Characteristics, in situ behaviour and applications].

This study is an updating on synthetic prostheses used today to repair incisional hernias, eviscerations and abdominal wall defects due to a severe infection or a parietal excision of malignant tumours. The present prostheses are the fruits of the constantly developing plastic industry. Their characteristics and types (mesh or patch), together with the materials they are made of, are studied taking this development into account.

Magnetic resonance imaging of the liver by oblique sections.

The authors have applied magnetic resonance imaging (MRI) to the anatomic study of the liver by comparing cadaveric sections with those obtained with MRI. This study deals with sections oblique in relation to a sagittal or frontal plane, whose orientation is determined from landmarks visible on transverse sections. Oblique sections were made in 10 cadavers using an original method.
