[Bisegmentectomy 7-8: importance of preoperative diagnosis of a right inferior hepatic vein]. / Bisegmentectomie 7-8: intérêt du repérage pré-opératoire d'une veine hépatique inférieure droite (VHID).

The extent of hepatic resection is often determined by the hepatic veins and their relation to the tumor. A need to transect the right hepatic vein at its entry into the vena cava indicates a need to remove the entire right posterior segment. About six cases, the aim of the study was to remind that under certain circumstances the posteroinferior area may be preserved. The circumstances which allow such preservation are the presence of a stout inferior right hepatic vein and the ability to recognize the presence of the vein in the preoperative staging. In patients with possible impaired hepatic function (cirrhosis, chemotherapy), preservation of hepatic parenchyma is an important consideration during resection for hepatic tumors.

[Meckel's diverticulum Diagnosed by CT-Enteroclysis]. / Diagnostic d'un diverticule de Meckel hémorragique par entéroscanner.

The authors report the case of a 24 year old woman presenting with acute lower GI hemorrhage caused by a Meckel's diverticulum. Diagnosis was made by CT-enteroclysis and confirmed at surgery. This new imaging technique will be briefly described and compared to the other more traditional small bowel imaging techniques. The authors will then present the CT-enteroclysis imaging features of this congenital anomaly.

[Small bowel diverticulitis: the role of CT]. / Diverticulite de l'intestin grêle: intérêt du scanner.

The authors report a case of small bowel diverticulitis diagnosed by computed tomography. They describe the CT findings and review its advantages for diagnosis of this uncommon entity that is rarely suspected at physical examination.

Percutaneous ethanol injection vs. resection in patients with small single hepatocellular carcinoma: a retrospective case-control study with cost analysis.

BACKGROUND: Percutaneous ethanol injection and hepatic resection are the most widely used curative therapeutic options for patients with compensated liver disease and small hepatocellular carcinoma. AIM: To compare percutaneous ethanol injection and hepatic resection in a selected group of consecutive French patients with a single hepatocellular carcinoma, smaller than or equal to 50 mm, in terms of survival, recurrence rate of malignancy and direct costs. METHODS: The analysis of two contemporary cohorts of Child-Pugh A or B patients with a single hepatocellular carcinoma of < or = 50 mm treated by percutaneous ethanol injection (n=55) or hepatic resection (n=50). RESULTS: Long-term survival was not significantly different between the two groups when the size of hepatocellular carcinoma was less than 30 mm. However, the survival of patients with hepatocellular carcinoma larger than 30 mm was higher after hepatic resection than after percutaneous ethanol injection (P=0.044). The cumulative direct costs were significantly higher in patients treated by hepatic resection than in those treated by percutaneous ethanol injection regardless of the tumour size. The calculated costs per month of survival in patients treated with percutaneous ethanol injection and hepatic resection were 999 vs. 3865 euros, respectively (P < 0.001). CONCLUSIONS: Percutaneous ethanol injection is more cost effective than hepatic resection in patients with a single hepatocellular carcinoma smaller than 30 mm. However, in patients with a larger tumour, long-term survival is higher after hepatic resection.

[Meckel's diverticulitis in the adult: diagnosis by computed tomography]. / Diverticulite de meckel chez l'adulte: diagnostic par tomodensitométrie.

The authors report a case of acute Meckel's diverticulitis diagnosed by CT in a 38 year old patient. The authors describe the value of CT for diagnosis and evaluation of disease extent in a patient presenting with non specific symptoms.

[Ultrasound guided alcohol ablation of the celiac plexus in oncology patients with abdominal pain]. / Alcoolisation coeliaque échoguidée dans les douleurs solaires néoplasiques.

PURPOSE: The authors report results of a retrospective study evaluating the efficacy of US-guided alcohol ablation of the celiac plexus in 26 patients with chronic cancer-related abdominal pain. They review the interest of this imaging technique for guidance. PATIENTS AND METHODS: Thirty US-guided alcohol ablations were performed in 26 patients. Twenty-two of them had a prancreatic malignancy, 3 had a gastric cancer and 1 had an esophageal cancer. RESULTS: 72% of patients experienced significant pain relief with at least 50% decrease in morphine requirements for two months. Four patients underwent a second ablation because of persistent pain and 3 of them experienced relief. CONCLUSION: Celiac plexus ablation is considered to be one of the most effective treatments for chronic cancer-related abdominal pain, often used as an adjuvant treatment in the pain management strategy. US guidance is advantageous because it is simple and accurate and enables quick needle placement.

[Malignant obstructive jaundice: the role of percutaneous metallic stents]. / Ictères obstructifs néoplasiques: apport des prothèses métalliques percutanées.

OBJECTIVES: Efficiency evaluation of percutaneous metallic stents in palliative treatment of malignant biliary obstruction. METHODS: One hundred sixteen percutaneous metallic stents were implanted in 80 patients with malignant biliary obstruction. Thirty-five patients had hilar obstruction, 32 patients obstruction of the common bile duct and 12 patients obstruction of a bilioenteric anastomosis. RESULTS: Adequate biliary drainage was achieved in 79 patients. Early complications occurred in 23.75% of patients; 12.5% of patients died within 30 days. The procedure-related mortality rate was 5%; 18.75% of patients showed recurrent jaundice after an average of 175 days. CONCLUSION: Percutaneous metallic stents are an efficient means of treating malignant biliary strictures, particularly of upper biliary obstructions. However, this treatment has risks and limits that require careful patient recruitment.

[Percutaneous self-expanding metallic endoprosthesis and malignant biliary stenoses]. / Endoprothèses métalliques auto-expansibles percutanées et sténoses biliaires malignes.

METHOD: Thirty-five patients with malignant obstructive jaundice were given palliative treatment by percutaneous self-expandable metallic stents. Cholangiocarcinoma was the most frequent cause of biliary obstruction. The stricture was located in the hilum in more of 50% of cases. RESULTS: Adequate biliary drainage was achieved in 97% of cases. Median survival was 182 days. 11% of patients have died within 30 days. Early complications occurred in 31% of patients. 25% of patients have shown recurrent jaundice after an average of 180 days. CONCLUSION: Percutaneous self-expandable metallic stents are an efficient means treating malignant biliary strictures, particularly of upper biliary obstructions.

[Percutaneous drainage of peri-sigmoid abscesses or how to avoid colostomy]. / Drainage percutané des abcès péri-sigmoïdiens ou comment éviter une colostomie.

BACKGROUND: Percutaneous drainage can be a conservative option for abscess formation subsequent to acute inflammation of the sigmoid colon. CASE REPORTS: Three patients, aged 36, 65 and 77 years, were hospitalized for abscesses in the peri-sigmoid region. All three were treated with echoguided percutaneous drainage. The infectious phenomena regressed rapidly allowing secondary left colectomy 6 to 8 dais later with immediate colorectal anastomosis. DISCUSSION: Hartman's resection is indicated for perforated diverticules of the sigmoid colon with formation of pelvic abscess and must be followed by a second laparotomy to re-establish colo-rectal continuity. Percutaneous drainage can successfully treat the acute septic component an allow planning the surgical procedure later in better conditions. With percutaneous drainage, temporary colostomy can be avoided in selected patients.

Percutaneous self-expandable metallic stents and malignant biliary strictures.

Thirty-five patients with malignant obstructive jaundice received palliative treatment using percutaneous self-expandable metallic stents. Cholangiocarcinoma was the most frequent cause of the biliary obstruction. In more than 50% of cases, the stricture was located in the hilum. Adequate biliary drainage was achieved in 97% of cases. Median survival was 182 days, and 11% of patients died within 30 days. Early complications occurred in 31% of patients, and 25% of patients showed recurrent jaundice after an average of 180 days. Percutaneous self-expandable metallic stents are an efficient means of palliatively treating malignant biliary strictures, particularly high biliary obstructions.
