Acute hemoperitoneum caused by rupture of omentum adhesions after running.

The case of a 37-year-old man in whom a massive hemoperitoneum developed a few hours after running is described. The patient disclaimed any trauma and clearly noted that symptoms appeared after running. Findings at laparoscopy showed that the bleeding was caused by the rupture of adhesions between the omentum and left inguinal abdominal wall. These adhesions, which had resulted from a previous laparoscopic transperitoneal bilateral inguinal hernia cure, were resected. Recovery was simple and follow-up assessment was uneventful. Hemoperitoneum secondary to the rupture of intraperitoneal adhesions is very rare in the absence of precipitating trauma. However, the trauma can be trivial. Rupture of intra-abdominal adhesions has been described after sexual intercourse or mobilization of the patient under general anesthesia. Disruption of adhesions by insufflation or mobilization of organs under laparoscopy also is reported. The transperitoneal approach to laparoscopic treatment of inguinal hernia can be responsible for late intestinal obstruction caused by intra-abdominal adhesions, but late hemorrhagic complication has not yet been reported.

Spontaneous rupture of the pancreaticoduodenal artery: three cases.

We report 3 cases of spontaneous rupture of pancreaticoduodenal arteries (PDA). In the first case, an aneurysm of the PDA was demonstrated with stenosis of the celiac trunk; in the second case occlusion of the hepatic artery was shown. In both cases, arterial pancreatic arcades were enlarged and blood flow was retrograde from the superior mesenteric artery. Local high intravascular pressure due to retrograde blood flow through the arterial pancreatic arcades was thought to be the cause of aneurysm development and arterial rupture which necessitated surgical intervention. The third patient presented with a mycotic aneurysm that could be treated by intra-arterial embolization. The characteristics of this rare affliction are discussed, as is the treatment which first entails percutaneous embolization.

[Carney's syndrome: 2 new cases].

The association of gastric leiomyoblastomas, pulmonary chondromas and extra-adrenal paragangliomas has been called "Carney's Triad" since 1977. It is incomplete when only two of these lesions are present. 42 cases has been published. We report observations of two young women with gastric leiomyoblastomas and pulmonary chondromas; one of them also had an adrenocortical adenoma.

[Study with flow cytometry of the peritumoral mucosa adjacent to colorectal cancers].

Tumour and peritumoral mucosa were analyzed using flow cytometry in 21 consecutive patients operated on for colorectal carcinoma. Thirteen tumours were DNA aneuploid. No foci of aneuploidy bordering the tumours were detected, regardless of the tumour type. On the other hand, a significant decrease in the proliferative index was observed adjacent to the DNA aneuploid tumours. This study provides an additional argument for segmentary excision in colorectal cancers. Complementary studies are still required to specify the mechanisms of proliferation inhibition in the area of the DNA aneuploid tumours.

[Cystic lymphangiomas of the pancreas. Three new cases].

Cystic lymphangiomas are vascular dysembryoplastic lesions. Three pancreatic cases are reported. Preoperative diagnosis is rarely possible and laparotomy is mandatory. Complete resection prevents recurrence but excessively aggressive surgery is not required for this benign disease.

[Bladder incarceration in a Spigelian hernia].

A patient presented with bladder in an incarcerated Spigelian hernia. Diagnosis was made by clinical examination and ultrasound imaging. Surgical treatment ensured good parietal refection. Such a case has not been previously reported in the literature.

[Gastric metastases of ovarian adenocarcinoma. Apropos of a case].

A case report and review of literature. Four types of neoplastic dissemination exist in presence of ovarian adenocarcinomas. Commonly, these tumors metastasize along intraperitoneal ways or lymphatic channels. Less frequently, the tumors are invading surrounding organs by direct extension. Rarely, there is a hematogenous dissemination. The observation of a gastric metastasis is reported; we consider it as a hematogenous one. Reviewing the literature, we find few similar cases. Gastric metastases originate more frequently from malignant melanomas, adenocarcinomas of the breast and bronchogenic tumors.

[Appendiceal mucoceles. Pathophysiology and therapeutic indications].

Appendiceal mucoceles (AM) are rare lesions of the appendix, characterized by an accumulation of mucus. Two main pathogenic mechanisms may be invoked to explain their development. Firstly, AM are secondary to an obstruction of the appendiceal lumen for a wide variety of reasons. Secondly, they may be due to tumours of the appendix, whether malignant (cystadenocarcinomas) or benign (cystadenomas), responsible for a hypersecretion of mucus. Intraperitoneal mucinous effusion (IME) develops when appendiceal perforation occurs, especially with malignant AM. We found 13 retention AM and in most a definite obstructive lesion was present. There were 3 malignant AM, all associated with a neoplastic IME. While they are frequently described in the literature, no cystadenoma was observed in these series. Clinical symptoms are often confusing, but paraclinical investigations may lead to preoperative diagnosis. Appendectomy is the treatment of retention AM and cystadenoma. Their prognosis is related to other associated diseases, namely ovarian and colorectal tumours, but is otherwise good. Cystadenocarcinomas require a right hemicolectomy with evacuation of IME but their prognosis is poor.

Ruptured subcapsular hepatic haematoma secondary to "HELLP syndrome".

We report the history of a pregnant woman who suffered from a ruptured hepatic subcapsular haematoma, responsible for a major haemoperitoneum. This rare event, final evolution of the "HELLP Syndrome" led us to review pathophysiology and treatment of the syndrome.
