L’hydatidose péritonéale. À propos de 12 cas

STUDY AIM The aim of this retrospective study was to report on 12 cases of peritoneal hydatidosis observed in the same hospital from 1989 to 1998. PATIENTS AND METHODS Four men and 8 women (mean age: 37 years) were included in the study. Four of them had been operated on for liver hydatidosis, 3 to 9 years before. The peritoneal hydatidosis was asymptomatic (n = 2), revealed by pain and/or fever (n = 9) and by hydatid peritonitis (n = 1). Diagnosis was performed by ultrasonography in seven cases out of 10. Preoperative treatment with albendazole was given to one patient only during 1 month. All patients were operated on. Peritoneal cysts, with different locations, were secondary in 11 patients. Nine patients had concomitant liver hydatidosis and two concomitant retroperitoneal hydatidosis. Hydatid cysts were usually sterilized with oxygen water and treated by resection of the protruding dome. Postoperative treatment with albendazole was given to five patients. RESULTS Postoperative complications occurred in five patients: intestinal occlusion, abscess in a residual cavity, purulent fistulas, biliary fistulas with a favorable issue. With a mean 38-month follow-up, all patients were alive, with only one recurrence in a liver hydatid cyst. CONCLUSION Peritoneal hydatidosis was secondary in 11 out of 12 patients. Diagnosis was performed with ultrasonography in seven out of 10 patients. All patients were operated on. With a mean follow-up of 38 months, only one recurrence has been observed.

Delayed repair for traumatic abdominal wall hernia: is it safe?

Abdominal wall hernias after trauma have been recognized for more than a century, with the first case reported as occurring after a fall. Traumatic abdominal wall hernias (TAWHs) after blunt trauma are uncommon. The timing of definitive repair, early or delayed, is not clear. We report a case on TAWH and mesenteric avulsion, highlighting the reasons for immediate or delayed repair. A single case study can hardly be considered as a basis for profound changes in the management of post traumatic hernias. However, damage to all layers of the abdominal wall indicates high-energy trauma. In such cases, the damage is not, in all probability, limited to the integumentary system. For the moment, the timing of surgery in any TAWH should be considered differently according to the trauma, the wall defect, clinical and radiological findings, associated injuries, and the clinical status of the patient.

Medial Pancreatectomy for a Neuroendocrine Tumor Invading the Splenic Artery and Vein

CONTEXT Pancreatic tumors in the midportion have traditionally been treated by an extended right or left pancreatectomy. A medial or central pancreatectomy is an alternative technique for benign or low-grade malignant neoplasms located to the left of the gastroduodenal artery and close to the splenomesenteric confluence. CASE REPORT A 38-year-old woman with no previous surgical history presented with epigastric abdominal pain. A computed tomography scan showed a 4 cm heterogeneous lesion within the pancreatic body. This tumor invaded the splenic artery and vein. There was no postoperative diabetes mellitus or exocrine insufficiency. The patient continues to be well after a 10-month follow-up without pancreatic insufficiency or local recurrence, and CT has demonstrated splenic perfusion by the collateral vessels. CONCLUSION We believe that a medial or central pancreatectomy may be a safe procedure where there is involvement of the large splenic vessels by a low grade malignant pancreatic tumor and that a systematic splenectomy is not justified.

Sacral hemangiopericytoma involving the retrorectal space: Report of a case

A primary hemangiopericytoma (HP) of the bone is rare, because the vast majority of these tumors arise in soft tissue. This report presents a case of a hemangiopericytoma in the sacrum (S1–S2) with extension to the retrorectal space. Only a few cases of osseous hemangiopericytomas in the sacrum and involving the retrorectal space have so far been reported. The difficult diagnosis of HP and the surgical strategy was chosen according to the location of the lesion in the sacrum and retrorectal space. A local excision was indicated. A sacral resection should be considered for tumors below S4. This report demonstrated the safety of this strategy. Adjuvant radiotherapy is useful in HP. The value of chemotherapy is still doubtful, although patients with high-grade tumors or metastatic spread seem to gain substantial benefit. Due to the often unpredictable behavior of this neoplasm, extended follow-up is strongly recommended.

Anévrysme du tronc cœliaque: À propos d’un cas

Resume Les anevrysmes du tronc cœliaque sont rares, leur principale complication est representee par la rupture. Un traitement chirurgical est classiquement propose chaque fois que possible. Nous presentons un cas d’anevrysme du tronc cœliaque traite chirurgicalement. (J Mal Vasc 2006 ; 31 : 284-286).

Primary hydatid cyst of the retroperitoneum

Retroperitoneal contamination may occur during the natural history of hydatid disease. Primary hydatid cyst of the retroperitoneum is extremely rare. The authors report a case of a giant retroperitoneal hydatid cyst. Clinicians and surgeons must be aware of this possibility and follow a policy of nonsystematic puncture of an abdominal cyst and avoid spillage during surgery. Symptoms are related to the size, location, or ensuing complications of a cyst. Its occurrence should be strongly suspected ahead of any abdominal cyst, especially in an endemic area, where it may act as a parasite. Total and careful surgical excision is the gold-standard therapy.

Osteochondroma developing from the xyphoid appendix into an abdominal wall scar from a previous laparotomy

We describe herein the case of a 45-year-old man who developed an osteochondroma from the xyphoid appendix into an abdominal wall scar from a laparotomy performed 4 years previously. To our knowledge, rare cases of osteochondroma of the xyphoid bone have been documented in the literature. As shown by the tumors rapid development during a period of only 4 years, osteochondromas arise from, or grow well under, inflammatory and cicatricial conditions. Periosteal contusion causing growth-plate cartilage migration and enchondral ossification seems to be the first presentation of osteochondroma.

Giant adrenal hemangioma: Unusual cause of huge abdominal mass

Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up.

Successful surgical treatment of extrahepatic biliary papillomatosis diagnosed with endoscopic retrograde cholangiopancreatography: a case report.

IntroductionBiliary papillomatosis is a condition characterized by multiple papillary tumors of variable distribution and extent within the biliary tract. Papillary carcinoma can develop in these lesions. It is a rare biliary pathological entity and its clinical features and outcome are not well known.Case presentationWe experienced a case of biliary papillomatosis in a 51-year-old North African man who presented with obstructive jaundice. Laboratory tests showed elevated bilirubin, alkaline phosphatase and gamma-glutamyl transpeptidase levels. Imaging (ultrasound and magnetic resonance imaging) was suggestive of Klatskin tumor associated to common bile duct stones. After endoscopic retrograde cholangiopancreatography, a balloon sweep retrieved friable tissue from his bile ducts. Histology demonstrated papillary adenomatous proliferation showing high-grade dysplasia and he was referred for surgical management.ConclusionsAlthough biliary papillomatosis is rare, it is a premalignant condition that should be well known and considered in all diagnoses of obstructive jaundice. We report a new case of biliary papillomatosis and highlight the contribution of endoscopic retrograde cholangiopancreatography in the diagnosis of this condition.

Gastric bronchogenic cyst presenting as a submucosal mass: a case report

IntroductionBronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection.Case presentationA 40-year-old North African man was admitted to our hospital with a gastric submucosal mass. An endoscopic ultrasound revealed a unilocular cystic mass located in the muscular layer. Its content was echogenic suggestive of mucus. Magnetic resonance imaging confirmed the liquid nature of the cyst and showed a high ratio of proteins. Based on these observations, the diagnosis of bronchogenic cyst was confirmed. An endoscopic monitoring was decided rather than surgery because of the small size of the cyst and the absence of symptoms.ConclusionAlthough gastric bronchogenic cysts are rare, they should be well known and considered in all differential diagnoses of gastric tumors. We report a new case of gastric bronchogenic cyst and highlight the contribution of morphological tests that currently allow a non-invasive diagnosis.
