Bicalcium phosphate filling-up after calvarial unicortical harvesting in maxillofacial surgery.

The calvarium is one of the most common donor sites for bone grafting in maxillofacial and craniofacial surgery. The quality of the bone and the few after-effects that arise in calvarium make it a very good choice for reconstruction, especially in preprosthetic surgery. Nevertheless, calvaria harvesting of the outer table can leave a depression on the scalp, which can be perceptible and palpable.

[Feasibility of prosthesis insertion by laparotomy as palliative treatment for malignant duodenal stenosis].

The authors report a preliminary series assessing the feasibility of duodenal stenting using a surgical approach. The study included 16 patients with a malignant duodenal outlet obstruction for whom a biliaryobstruction necessitated a laparotomyor following an endoscopic stenting failure. The stent was efficient in 15 patients with a complete relieve of obstruction.

[How to reduce morbidity in celioscopic biliary surgery. Apropos of a series of 446 consecutive operations].

We reported a series of 446 consecutive cholecystectomies performed laparoscopically between June 1990 and January 1993. There were 354 females and 92 men, mean age 53 +/- 17 years. Laparoscopic cholangiography was attempted in 410 cases (92%) and led to the discover of a stone in the main bile duct in 18 cases (4%) and an abnormal insertion of the bladder duct in 30% (6.
