[Duodenal leiomyoblastoma. Apropos of a new case and review of the literature].

The authors report a new case of duodenal leiomyoblastoma. Since local anatomical factors were favorable, the tumor was removed by resecting the entire second portion of duodenum with reanastomosis of the remaining ends. This case can be added to the very small number of cases reported in the literature regarding leiomyoblastoma at this site in the gastrointestinal tract. Since diagnostic is difficult, and often made per-operatively following and acute complication, a precise topographical study of the region needs to be performed. It is only by this means that a completely safe operative procedure may be chosen and performed. From an anatomo-pathological viewpoint, several criteria exist to distinguish the potentially benign from the potentially malignant form. However, this remains to be confirmed given the controversial aspects of the subject. Study has mainly involved gastric localisations where a greater number of lesions have been found. At present, only time will show whether these tumors are benign or malignant.

[The extra-hepatic bile ducts. Apropos of a new case of abnormalities].

A double anomaly of extrahepatic biliary pathways was detected in the same patient. The first anomaly involved the cystic duct, which emptied into the third part of duodenum, the second anomaly the common bile duct which was implanted into the right side of the cystic duct one centimeter from the papilla. An anomaly of this type has not been reported previously in the literature and surgeons should be aware of its possible occurrence.

[Esophageal and gastric leiomyoma. Apropos of a case with double localization].

A case of double localization of a leiomyoma is reported and used as a basis for an update review of the relevant literature. Esophageal and gastric leiomyomas, of relatively simple diagnosis by radiologic and endoscopic imaging, require surgery in most cases: enucleation of esophageal and resection of gastric tumors. Leiomyoma of esophagus is usually diagnosed during investigation of atypical clinical symptomatology or when it is associated with another disorder, such as hiatus hernia as in the present case. Leiomyoma of stomach is usually revealed by a complication initially, frequently of the hemorrhagic type. Despite the absence of documented data on leiomyoma of double localization in two digestive organs simultaneously, this possibility does exist and extensive digestive investigations are necessary prior to therapy.

[Mechanism of hernia of the groin].

Utilitarian aspects of hernia pathogenicity are envisaged to assist comprehension of surgical gestures, the choice of effective techniques and the abandon of those which are not and may be of medicolegal interest: all inguinal hernias are due to parietal weakness. Anatomical factors are studied based on data from dissection, from in front backwards and then from behind forwards, from which certain major notions are drawn: that of role of transverse fascia in imperviousness to intra-abdominal pressure; that of uniqueness of inguinal hernias, all of which cross the transverse fascia in the region of the regional osteomuscular framework; that of the necessary degradation of musculofascial plane for a hernia to develop, with as a corollary the need for inguinal imperviousness at the transverse fascia level to be restored. Factors may be present that increase the "natural weakness" of the groin: anatomical variations affecting inguinal triangle; biological disorders affecting inguinal structures (aponeurotic and fascial senescence, collagen diseases, musculo-tendino-aponeurotic dystrophy). A breakdown in mechanisms of protection against increased intra-abdominal pressure promoted a summary of features defining intra-abdominal pressure under physiologic conditions and classical herniogenic circumstances. A summary of pathogenic mechanisms of inguinal hernia is presented while emphasizing the two principal theories: the saccular theory and that of musculo-fascial weakness, with their consequences for choice of therapies to be opposed to the polymorphism of hernial lesions.

[A simple technic of true pyroloclasia: crushing with a rubber-sheathed clamp].

For more than 10 years the authors have been using a pyloroclasia derived from the Hivet and Lagadec technique of digital dilatation, in place of gastric drainage pyloroplasty. The procedure is simple, effective and easily reproducible. It only requires a rubber sheathed clamp to crush the anterior part of the pyloric annulus; the pyloroclasia is then confirmed by digital exploration. This technique has been used regularly without any per-operative problem and post-operative complications ascribable to pyloroclasia. The long-term results have been satisfactory with complete absence of gastric stasis or biliary reflux. When performed, post-operative radiography and fibroscopy have shown adequate gastric emptying and little changes in pyloric morphology. Pyloroclasia is simpler and less septic than pyloroplasty, and it reduces the incidence of dumping syndrome. Pyloroclasia with a rubber sheathed clamp is simpler and more reproducible than digital pyloroclasia. In view of its regularly good results it can certainly be recommended.

[Double breast and vertebral plasmacytoma. Acute myeloblastic leukemia 8 years later].

We report in a 40 year-old woman a bifocal mammary and vertebral plasmocytoma attended by surgery and "preventive" chemotherapy. Eight years later, an acute and apparently non secondary myeloblastic leukemia is observed without sign of diffuse myelomatosis. Plasma cell tumors of the breast are uncommon. Eleven cases have been published, combining solitary plasmocytoma and infiltration occurring in multiple myeloma.
