[Retrospective and comparative study of the medicoeconomical impact of a new mesh in the treatment of anterior abdominal wall incisinal hernia]. / Etude comparative rétrospective de l'impact médicoéconomique d'un renfort innovant dans la cure des éventrations de la paroi abdominale antérieure.

STUDY AIM: Determine the gain of hospitalization cost using a new intraperitoneal mesh compared to the retro-muscular pre-fascial implantation of a polyester mesh. PATIENTS AND METHODS: From January 1998 to June 2000, 52 patients with incisional hernia of the anterior abdominal wall were operated using intraperitoneal Parietex composite Mesh. The cost of surgery, anesthesia and hospitalization in this group were compared to similar data from a group of 21 patient where a Mesrsuture mesh in a prefascial retromuscular position was used. RESULTS: Parietex Composite Mesh in intraperitoneal position allows a significative reduction in surgery time, anesthesia time and hospitalization. The clinical results were confirmed by cost savings. CONCLUSION: Using new innovative medical device changing surgery technique insures significant cost saving despite its initial additional cost and increases patient's comfort during hospitalization.

[Small intestinal stromal tumors with skenoid fibers. Clinicopathological study of three cases]. / Trois observations de tumeurs stromales de l'intestin grêle à fibres en écheveau.

Gastrointestinal stromal tumours (Gist) are mesenchymal tumour with uncertain prognosis occurring in the gastrointestinal tract wall. For clinicians, these tumours raise two problems: to establish the diagnosis and to determinate the future behaviour for the choice officient therapeutics. For the diagnosis the new marker c-KIT is useful. A new treatment with an inhibitor of c-KIT has given encouraging results. currently there is no consensus on specific cut-points to distinguish as low or high risk (i.e., malignant) Gist. For metastases-free Gist, the prominent histopronostic markers are size, mitotic index and localization of the tumour. The small intestine Gist have the reputation to be more aggressive than in other localization. Skenoid fibers in small intestine Gist could be a marker of good prognostic. The authors reported three cases of small intestine Gist with skenoid fibers. The discussion point out the significance of this particular morphological aspect.
