Myxoid liposarcoma: a rare soft-tissue tumor with a misleading benign appearance.

Background: Lipoma is by far the most common of all benign soft-tissue tumors which far outnumber malignant tumors. Soft-tissue sarcomas are malignant tumors and are usually named for the type of tissue in which they begin. Liposarcoma (LPS), which arises in the fatty tissue, is rather an uncommon soft-tissue tumor.

[The remaining indications for open surgery in common bile duct lithiasis].

Once with the continuous development of mini-invasive procedures, the open surgery indications in the treatment of CBD stones are decreasing. Between January 1986 and December 1987, 514 patients with average age 60 years old (18-94) were treated for suspected or confirmed CBDS. Three distinctive periods were studied function of how the conventional surgery were either exclusive (group I), either together with the beginning era of laparoscopy (group II), or together with institutionalised laparoscopy (group III).

Management of common bile duct stones by laparoscopic cholecystectomy and endoscopic sphincterotomy: pre-, per- or postoperative sphincterotomy?

Background/aims: The aim of this study was to evaluate the treatment of common bile duct stones (CBDS) by endoscopic sphincterotomy (ES) and laparoscopic cholecystectomy (LC), ES being performed either pre-, per- or postoperatively.

Methods: Between January 1990 and June 1997, 386 patients with a median age of 60 (range 18-92) years were treated for suspected or confirmed CBDS. The CBDS were uncomplicated in 264 cases (70%) but associated with a complication in 122 cases (30%), namely, cholangitis (69 cases) or acute pancreatitis (53 cases).

[Laparoscopic treatment of gastroesophageal reflux using fundoplication. Midterm results].

Unlabelled: The aim of this study was to see whether the results of surgical treatment of gastroesophageal reflux disease (GERD) by laparoscopic fundoplication were satisfactory and stable over time.

Patients And Methods: From July 1992 to September 1996, 161 patients with medical treatment-dependent GERD were operated. 17 patients were excluded from the study (conversion or immediate laparotomy).
