[Presacral myelolipoma].

Presacral myelolipoma is a rare benign tumour of unknown aetiology, composed of mature adipose tissue with intermixed normal haematopoietic cells. Computed tomography is of help in the diagnosis but biopsy is mandatory in order to avoid unnecessary surgery. A case is reported.

[Failure of the treatment of eventrations and hernias with the PTFE plate (111 cases)].

Patch repair using a PTFE prosthesis was performed in 111 patients over a 5-year period for treatment of incisional hernias (64 cases), inguinal hernias (41 cases, including 29 recurrences), umbilical hernias (4 cases), epigastric hernias (2 cases), lumbar hernias (1 case) and abdominal wall defects after resection for endometriosis (2 cases). The surgical technique was limited to simple patch closure of peritoneomuscular defects without myoplasty. Follow-up was evaluable for every patient and 84 cases have been reviewed clinically by 2 surgeons. 83 patients (86 patches) were followed for at least 1 year (74.8%). Post operative mortality was nil. Morbidity was 17.5% (20 cases, including 14 hematomas, 2 intraperitoneal bleedings, 3 cases of local sepsis, 1 hydrocele). Recurrence rate was 42.2% for incisional hernia repair (27 cases) and 14.6% after inguinal hernia repair. Three out of 4 umbilical hernias and 1 out of 2 epigastric hernias recurred. 14 patients underwent reoperation for recurrent hernia (11 incisional and 3 inguinal). Absence of fibrotic reaction around the PTFE prosthesis was noted in every case and appeared to be the main factor of recurrence. Our experience suggests that patch technique with PTFE prosthesis should be abandoned for the repair of abdominal wall defects.

[Pyloric stenosis caused by gallstone (Bouveret's syndrome). Presentation of a further case].

The Bouveret's syndrome is a rare complication of a bilio-digestive fistula, where a big stone occludes the pyloro-duodenal region. The clinical symptomatology is atypical, symptoms of the disease are acute and only in fifty per cent of cases it is possible to have a positive anamnesis for biliary lithiasis. The evolution of the occlusion is generally rapid. The clinical case we are in possession of, shows a particularly chronic evolution with a 15 month sub-occlusive symptomatology that caused a massive gastric dilatation. The diagnosis of Bouveret syndrome was set forth during operation, as generally happens in about 50% of cases. The surgical treatment is still the only one capable to solve the obstruction of the alimentary canal and the bilio-digestive fistula at the same time.
