[Duodenal duplication: pathologic anatomy and embryogenesis. Case report in an adult].

Duodenal duplication is a rare congenital entity and less than 100 cases have thus far been reported in the literature. This was first described by Sanger in 1880. By definition, they are located in or adjacent to the wall part of the gastrointestinal tract, have smooth muscle in 2 layers and are lined by alimentary tract mucosa. With the case report of a 18 year-old patient with pancreatitis, we expose modern imaging procedure and surgical management. Although the exact etiology of enteric duplications is not known, the two main hypothesis are dysembryogenesis and dysorganogenesis.

[Mesenteric-portal confluence aneurysm].

The authors take interest in the portal aneurysm about the observation of a 52 year-old woman with an echographic lesion in the head of the pancreas. Radiological examination was done with abdominal CT and MRI. Because of no accurate diagnosis, an explorative laparotomy was done and showed an aneurysm at the junction of the portal and superior mesenteric veins. These lesions are rare: they can be acquired particularly with underlying hepatocellular diseases and portal hypertension; they can be congenital due to an incomplete obliteration of the right vitelline vein. If asymptomatic, only a close surveillance must be proposed.

[Portal hypertension in a patient with hepatitic C revealing an iatrogenic arterioportal fistula].

A 67-year-old man with anti-HCV positive serum, was admitted for hematemesis by variceal bleeding. Portal hypertension, which initially was thought to be caused by a post-hepatitis C cirrhosis, was due to a fistula between a right hepatic artery and a right branch of the portal vein. The fistula located under the right liver and the adjacent atrophic hepatic segments, were resected by a bi-segmentectomy VI-VII. The postoperative course was simple. The pathological study of the resected liver showed no cirrhosis but active hepatitis. This arterioportal fistula was probably iatrogenic. Sixteen years before, this patient had undergone a total gastrectomy for cancer, followed by a serious haemorrhage requiring a massive transfusion, which was responsible for the transmission of hepatitis C.

[Laparoscopic treatment of solid and cystic tumors of the liver. Study of 33 cases].

AIM OF THE STUDY: Laparoscopic liver surgery is still in its early stages. The aim of this study was to report our experience in the laparoscopic management of solid and cystic liver tumours. PATIENTS AND METHODS: From April 1991 to December 1999, 32 patients with various lesions of the liver underwent laparoscopic liver surgery. One group of patients presented with cysts (n = 15) (11 giant solitary cysts and 4 polycystic liver diseases) and one group of patients presented with solid tumours (n = 18): focal nodular hyperplasia (n = 8), haemangioma (n = 6), adenoma (n = 2), isolated metastasis from a colonic cancer (n = 1) and hepatocellular carcinoma (n = 1). Fifteen cyst fenestrations and eighteen liver resections were performed via a laparoscopic approach including 1 right lobectomy, 5 left lateral segmentectomies, 2 subsegmentectomies IVb, 1 segmentectomy III and 9 non-anatomical resections. RESULTS: Conversion to laparotomy was performed in one case (3%) at the end of the operation (patient who had successfully undergone left lateral segmentectomy for hepatocellular carcinoma) to check the resection margins and surgical transection had been performed in healthy parenchyma. Mean diameter of solid tumours was 6.5 cm and 15.7 cm for solitary cysts. The mean operating time for hepatic resections was 232 minutes. There was no postoperative mortality. Complications occurred in one case for each group and consisted in intestinal stricture through a port site requiring intestinal resection. Mean postoperative hospital stay was 5.6 days for solid tumours and 7.5 days for cystic lesions. In the group of cystic lesions, the recurrence rate was 50% with a 5.5-months follow-up. CONCLUSION: Laparoscopic liver surgery can be safely performed, but requires a good experience in open hepatic surgery and laparoscopic surgery. The laparoscopic approach is indicated in patients with symptomatic or atypical benign solid tumour, giant solitary cyst and polycystic liver disease, located anteriorly on the liver. Indications for malignant lesions have not been clearly defined and require further information.

Early experience with laparoscopic approach for solid liver tumors: initial 16 cases.

OBJECTIVE: To evaluate the feasibility and outcome of laparoscopic hepatectomy in patients with solid liver tumors. SUMMARY BACKGROUND DATA: Although the laparoscopic approach has become popular in the surgical field, the value of laparoscopy in liver surgery is unknown. METHODS: Fifteen patients with solid liver tumors underwent 16 consecutive laparoscopic resections at the authors' institution between 1994 and 1999. Indications were symptomatic hemangioma, focal nodular hyperplasia, liver cell adenoma, isolated metastasis from a colon cancer, and hepatocellular carcinoma. The laparoscopic procedure was performed using four to seven ports (four 10-mm, two 5-mm, and one 12-mm). RESULTS: One patient underwent a major hepatic resection (right lobectomy); the others underwent minor hepatic resections (left lateral segmentectomies, IVb subsegmentectomies, segmentectomy, and nonanatomical excisions). The laparoscopic procedure was uneventful in 15 patients; one patient required conversion to open laparotomy because of inadequate free surgical margins. CONCLUSION: Laparoscopic surgery of the liver is feasible. The use of this new technical approach offers many advantages but requires extensive experience in hepatobiliary surgery and laparoscopic skills. The authors' experience suggests that laparoscopic procedures should be reserved for benign tumors in selected cases. Its application must be verified by further studies.

[Bilobar Thyroid Agenesis].

A case of a 27-year-old female patient presenting with bilateral agenesis of the thyroid gland and a benign euthyroid adenoma of the isthmus and the pyramidal lobe is reported. The patient had for several years been followed for a cystic nodule that was presumed to have developed from the left thyroid lobe, having recently increased in size. Scintigraphic and echographic studies evoked the absence of right lobe. Direct examination at cervicotomy found hypoplasia of the two lobes. This report highlights the similarity of this rare anomaly to widely known hemiagenesis.

[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.
