[Ruptured hepatocarcinoma. Report of 22 cases].

STUDY AIM: Spontaneous rupture of hepatocellular carcinoma (HCC) causing massive hemoperitoneum is a critical and life threatening complication. The study aim was to report a retrospective series of 22 cases observed in the same centre. PATIENTS AND METHODS: From 1978 to 1998, 22 patients (18 males and four females, mean age: 63 years, range: 18-83) were treated for ruptured H.C.C involving a cirrhotic liver in 17 cases and a normal liver in five cases. In 14 cases, the diagnosis of acute hemoperitoneum indicated an immediate laparotomy. The site of rupture was predominant in the left lobe (eight cases). The surgical treatment was: left lobectomy (n = 7), right hepatectomy (n = 2), excision (n = 4), hepatic artery ligation (n = 5), direct hemostasis (n = 4). RESULTS: Postoperative mortality was 45.4%. Among the 12 survivors, nine died within a delay of 6 to 29 months. Three patients were still alive at the time of this study at 32, 40 and 66 months. CONCLUSION: Acute rupture of HCC requires emergency procedures with a high risk of mortality. Curative operation with hepatic resection is the most effective procedure but is not often feasible because of the spreading of the tumor or/and the cirrhosis. The ligation of hepatic artery seems to be an alternative procedure to obtain an immediate hemostasis. Fissuration allows performance of complementary explorations and possibly preoperative arterial embolization with better immediate results.

[Current treatment of closed injuries of the liver: benefits and pitfalls].

STUDY AIM: The management of blunt hepatic trauma has been modified by the development of conservative methods. Risks and pitfalls of this new approach must be determined. PATIENTS AND METHODS: From January 1985 to September, 1998, 130 patients with blunt hepatic trauma were treated by the same team. Among them, 38 patients were referred from another centre (21 already having undergone operations). Eighty patients (61%) had an initial non operative management and 50 patients (39%) underwent emergency laparotomy. Perihepatic packing was performed in 24 patients, hepatic sutures in 22, limited hepatic resection in six, and major hepatectomy in two patients only. RESULTS: There were three deaths in the non operative management group (mortality rate: 3.5%) and 11 patients required a secondary laparotomy: four for haemorrhage, one for enteric injury, two for acute pancreatitis, one for bile leakage, one for subphrenic abscess, one for acute cholecystitis. There were 14 deaths in the emergency laparotomy group (mortality rate: 28%), including four intraoperative deaths due to haemorrhage and two due to abdominal compartment syndrome. CONCLUSIONS: In the nonoperative management group a close clinical survey of the patient is necessary and a secondary laparotomy often indicated. In the operative management group, early packing requires reintervention if the patient is unstable. Alternative means of temporary closure may allow coverage without tension in order to avoid the abdominal compartment syndrome.

[Self-expandable metal stent in the treatment of obstructive cancer of the left colon. Preliminary results and review of the literature].

AIM: To report our preliminary experience with self-expandable metal stent in the treatment of acute malignant obstruction of the left colon and to review the literature on this specific subject. PATIENTS AND METHODS: From March to September 1999, 8 consecutive patients with a mean age 71 were admitted as an emergency for acute malignant obstruction of the left colon. A self-expandable metal stent was inserted under radioscopic and, in 4 cases, endoscopic guidance. The patients then underwent bowel preparation before operation, if required. RESULTS: There was no mortality. Bowel preparation was satisfactory in 6 cases. Complications occurred in 1 patient, who was operated on day one for peritonitis due to perforation of the tumour by the prosthesis inserted after dilatation. Another six patients were operated: 2 had resection followed by anastomosis; 3 had resection and anastomosis protected by ileostomy; 2 had Hartmann's procedure. The last patient retained the prosthesis as palliation. In the literature, self-expandable metal stent application in obstructed carcinoma of the left colon gives satisfactory results. CONCLUSION: Based on our experience and a review of the literature, we provide practical recommendations when inserting self-expandable metal stents for acute malignant left colonic obstruction.

Successful surgical management of a ruptured abdominal aortic aneurysm in a renal transplant patient. A case report.

With extended indications for renal transplantation and increasing survival, it can be expected that atherosclerotic vascular disease in the post-transplant patient will become more frequent. The authors report a case of a ruptured abdominal aortic aneurysm in a renal transplant recipient. A temporary axillo-femoral shunt was used to maintain perfusion of the renal graft during aortic cross-clamping. They review the literature and discuss the available methods for preserving renal function.

[Primary adenocarcinoma of the duodenum. Study of three cases and review of the literature].

The authors report three cases of primary adenocarcinoma, two concerning the duodenum and the third concerning the duodenojejunal junction. These rare tumours are characterized by polymorphic and non specific clinical signs. Diagnosis is suspected by upper gastrointestinal fibroscopy and barium swallow, and confirmed by biopsies. Prognosis varies according to histological differentiation and lymph node extension. Whipples operation is the sole curative procedure in the absence of local lymph node involvement. Cases of extensive invasion are managed by bilio-digestive by-pass.

[Inferior mesenteric arteriovenous fistulas. Report of a case].

We report a case of postoperative inferior mesenteric arteriovenous fistula. Arteriovenous fistula represents a rare disease. Symptoms are due to portal hypertension and distal ischemy. Treatment of these fistulas is embolization. Surgery is possible by ligature or excision of the fistula because vascularisation is obtained by Riolan arcade and hypogastric artery.

[Cecal volvulus].

The cecum is the second most common site of colonic volvulus after the sigmoid. The mechanism is torsion or hyperflexion of the enlarged, poorly-fixed, and hypermobile cecum. It presents clinically as an acute bowel obstruction with strangulation. Diagnosis can be made by plain abdominal X-ray in more than half the cases on the basis of cecal distention (with a classical "teardrop" or "comma" appearance), proximal small bowel distention with air-fluid levels, and a gasless distal colon. Barium enema shows lack of filling of the cecum, often with a "beaked" termination of the column of contrast. CT images are pathognomonic when they reveal a cecal "vortex". After surgical reduction of the torsion, ileo-cecal resection is usually the best therapeutic alternative. Cecopexy may be aDDrouriate in older and debilitated Datients if there is no concomitant cecal necrosis.

The value of fibrin sealant in thyroid surgery without drainage.

Fibrin sealant is widely used to achieve complete hemostasis in many fields of surgery. A retrospective review of the surgical management of 81 patients with thyroid diseases between 1992 and 1998 was undertaken to determine if drainage after thyroid surgery could be safely avoided and substituted by fibrin sealing before closure of the wound. Complications were few and resulted in one patient with hoarseness, four minor oedemas and one case of unexplained fever during 48 h. The subjective discomfort from the collar incision was unusual and aesthetic healing was obtained in most of the cases (93.8%). These results suggest that the application of fibrin sealant can be advocated in thyroid surgery as an adjunct to a good surgical procedure and perhaps that prophylactic drainage is unnecessary.

[Voluminous retroperitoneal liposarcoma. Apropos of a case and review of the literature].

The authors report a case of bulky retroperitoneal liposarcoma (6 kg) in a 42-year-old woman. This observation of liposarcoma is interesting in that diagnosis was incidental during check up for recent hypertension. The diagnosis was suggested by ultrasonography, essentially computed tomography and suspected by multiple subcutaneous lipomas. Treatment was exclusively surgical with complete tumor resection including the left adrenal gland. The authors review literature data of retroperitoneal liposarcoma. Because of frequent recurrency, follow-up of tumor resection must be made by CT scanning every six months. An aggressive surgical approach including adjacent organs if necessary and total excision of local recurrencies can improve long-term prognosis. Postoperative adjuvant radio- and/or chemotherapy does not effect survival.
