[Pseudomyxoma peritonei secondary to a teratoma of the omentum with a mucinous component of borderline malignancy]. / Pseudomyxome péritonéal secondaire à un tératome épiploïque à composante mucineuse de malignité frontière.

A mature cystic teratoma of the omentum occurred in a 37 years old woman who had an appendicectomy at the age of 8. This extragonadal teratoma contained a predominant mucinous glandular pattern of borderline malignancy, responsible for pseudomyxoma peritonei. Ovarian biopsies had only shown surface mucinous deposits at the time of the first laparotomy but two years later ovarian mucinous cystadenomas of borderline malignancy appeared. The patient developed intestinal obstruction, surround by mucinous retractile material and died four years and an half after initial diagnosis. This case is, to our knowledge, the first pseudomyxoma peritonei occurring from an extragonadal teratoma, the events chronology suggesting the secondary nature of the ovarian tumors.

[Uterine hemangiopericytomas. Two case reports]. / Hémangiopéricytomes utérins. A propos de deux observations.

The diagnosis of uterine haemangiopericytoma is still a matter of debate. The existence of haemangiopericytoma must be proven on the basis of classical histology, ultrastructure histology and immunohistochemical analyses. The diagnosis, even when apparently sure, must nevertheless be proven. We described two cases emphasizing the clinical and laboratory features of uterine haemangiopericytoma. Progress in nuclear magnetic resonance imaging, ultrastructural analysis and immunohistochemistry should help in confirming the diagnosis of haemangiopericytoma. Highly vascular leiomyoma or low malignity grade leiomyosarcoma have been mistakenly identified as haemangiopericytoma.

[Inflammatory pseudotumor of the urachus. A case]. / Pseudo-tumeur inflammatoire de l'ouraque. Une observation.

The occurrence in a 9-year old boy of a painful, prominent and solid mid-hypogastric tumour is reported. This clinically isolated muscular tumour was suggestive of sarcoma. En bloc resection of the tumour including the attached vesical cupula was performed. Histology showed that this large tumour was purely inflammatory and had developed from remnants of the urachus. This diagnosis must be considered whenever a suprapubic tumour is discovered. Since malignant transformation of urachus cysts is possible, surgical resection is advised.

[Volvulus of the sigmoid colon. Emergency resection and anastomosis]. / Volvulus du côlon sigmoïde. Résection anastomose en urgence.

Eleven cases of sigmoid volvulus in patients aged 76 years in average, without visible signs of necrosis on endoscopy, are reported. All patients were treated within 6 to 48 hours by colic resection and immediate restoration of continuity with a mechanical anastomosis. Morbidity was low, including one case of evisceration and one of pneumonia, and there was no mortality after three months. Early resection seems to prevent the risks of necrosis and recurrence, and to have a good prognosis for survival.

[Use of electrolyte solutions in surgery (author's transl)]. / Utilisation des solutions d'électrolytes en chirurgie.

The use of isotonic saline and Ringer's lactate in surgery has become widespread following the work of Shires on the sequestration of extra-cellular fluid in hemorrhagic shock. Their use both in military and civilian practice and during hemodilutions in cardiac surgery have shown their efficacy. During intensive care, the risk of pulmonary edema is insignificant when less than 4 liters are given daily. Apart from cases of severe renal failure, they increase diuresis and reduce post-operative renal failure. Their use in appropriate cases permits economies in blood transfusion.
