RATIONALE Diaphragmatic function is a major determinant of the ability to successfully wean patients from mechanical ventilation (MV). Paradoxically, MV itself results in a rapid loss of diaphragmatic strength in animals. However, very little is known about the time course or mechanistic basis for such a phenomenon in humans. OBJECTIVES To determine in a(More)
INTRODUCTION Anastomotic leakage is a severe complication after colorectal surgery which causes substantial morbidity and mortality and impairs the oncologic and functional outcomes. The incidence rate varies in the literature from 4% to 26%. Diagnosis is difficult. Clinical presentation and time management are closely related to prognosis. If subcutaneous(More)
Spontaneous haemoperitoneum due to ruptured intra abdominal varices with cirrhosis is rare and the diagnosis is generally difficult. Two cases of spontaneous intraperitoneal bleeding due to ruptures varices with cirrhosis are reported. One case is a ruptured portal cavernome and the other one is a ruptured varix of the gastrosplenic ligament. The(More)
BACKGROUND Hepatic artery pseudoaneurysm (HAP) is found in 1-2% of liver transplantation (LT) patients. The mortality associated with pseudoaneurysm formation after orthotopic LT is reported to be as high as 75%. Because of the rarity of complications, particularly when considered individually, much of the direction for the management of complications is(More)
UNLABELLED Biliary injuries after laparoscopic cholecystectomy are rare but serious. Their mortality rate can reach 9%. AIM OF THE STUDY Describe the management of biliary injuries after laparoscopic cholecystectomy in our center. PATIENTS Between January 1995 and June 2005, 27 patients (13 women, 14 men) were treated. The mean age was 53 years old(More)
The only arterial pathway available after liver transplantation is the hepatic artery. Therefore, hepatic artery thrombosis can result in graft loss necessitating re-transplantation. Herein, we present evidence of neovascularization at long-term follow-up in a series of transplant patients with hepatic artery thrombosis. We termed this phenomenon(More)
Liver transplantation is the recognized treatment for serious cases of alcoholic cirrhosis. However, due to their poor image within society, patients with alcoholic cirrhosis are often less referred to transplant centres. This is even more surprising since in terms of patient' and graft's survival, the results of transplantation are comparable, if not(More)
Paragangliomas (PG) are rare and often diagnosed in the young adult. One case of retroperitoneal preaortic paraganglioma localised between the celiac trunk and the superior mesenteric artery is reported. The management of paraganglioma involves endocrinologists, geneticists and surgeons but the only potentially curative treatment remains surgical resection.(More)
In 1994, a technique of omental flap interposition to cover the celiac and mesenteric vessels after pancreaticoduodenectomy was described. It aimed to isolate the pancreatic anastomosis from the vessels dissected during pancreaticoduodenectomy. In liver transplantation (LT), the omental flap was initially used to reduce the risk of hepatic artery (HA)(More)
