The purpose of this article is to describe potential complications following the most common image-guided (fluoroscopy, ultrasound or CT) percutaneous interventional procedures, both diagnostic and therapeutic, thoraco-abdominal and musculoskeletal, as well as to review risk factors and the best practice recommendations. Prior to any interventional procedure, it is necessary to ascertain the absence of any abnormality in coagulation, to secure enough time to explain the procedure to the patient, and to adhere to strict sterile technique. Indeed, infections and hemorrhagic complications are the principal causes of mortality and morbidity for all procedures. Following lung biopsy, CT scan detects an immediate pneumothorax in 30% of patients. Major complications following percutaneous liver biopsy occur within 3 to 6 hours. Following a percutaneous drainage, complications occur in less than 10% of cases. Following a radiofrequency thermal ablation of malignant tumors, the mortality rate is low (0,5 to 1,4%), infection and hemorrhage are the most frequent complications. While rare, septic arthritis is the main complication that can follow musculoskeletal procedures and is a cause of medical malpractice lawsuits brought by patients.

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.

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.

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.

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.

The authors report an exceptional and well-documented case of interruption of the retrohepatic segment of the inferior vena cava with an "azygos continuation", combined with absence of the portal vein. The only known combination of congenital anomalies of the inferior vena cava and the portal vein was that of an "azygos continuation" and a preduodenal portal vein. The double interruption, portal and inferior caval, may be associated with a disturbance of preferential flows induced by the left umbilical thrust. According to hemodynamic theory, the left umbilical flow is the determining factor in organogenesis of the portal vein and the retrohepatic segment of the inferior vena cava.

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.

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.

BACKGROUND: Cholecystectomy remains the best treatment for acute cholecystitis but may cause high morbidity or mortality in critically ill or elderly patients. METHODS: We report a retrospective study of ultrasonography-guided percutaneous cholecystostomy (USGPC) performed between 1988 and 1994 in 41 patients (mean age, 77.8 years; range, 42-95 years) as an alternative to surgery. RESULTS: Five patients (12.2%) died in the hospital, four (9.8%) subsequently underwent operation without complications, six (15%) had a recurrence of cholecystitis between 3 and 24 months after withdrawal of drainage, and 26 patients are cured without recurrence after a mean follow-up of 33 months (range, 3-67 months). CONCLUSIONS: USGPC appears to be the treatment of choice for high-risk patients, especially those with postoperative cholecystitis, severe acute calculous pancreatitis, or total parenteral nutrition.

Cystic dystrophy in heterotopic pancreas is characterized by the presence in the duodenal thickened muscularis of cysts corresponding to dilated ducts lined with exocrine epithelium. The pancreas proper is normal. Cystic dystrophy in heterotopic pancreas occurs mostly in men, in the periampullary region. Two cases, revealed by duodenal stenosis, are reported here. Symptoms and morphologic investigations favoured a diagnosis of malignancy: in one case, partial portal thrombosis was observed; this complication has not been previously described in association with cystic dystrophy in heterotopic pancreas. Endosonography was non-contributory in these 2 cases because of duodenal stenosis. A pancreaticoduodenectomy was performed associated in one case with portal thrombectomy. Pathologic findings allowed diagnosis of cystic dystrophy in heterotopic pancreas.
