[Krukenberg tumour: diagnostic findings and surgical therapy. Recent acquisitions].

The authors report on their experience with two cases of Krukenberg's tumour treated at Chioggia Hospital in patients admitted for pelvic tumours. The clinical manifestation of Krukenberg's tumour is mainly related to the presence of the pelvic mass even in advanced forms of gastrointestinal cancers. The authors stress the importance of an adequate follow-up of premenopausal patients with a previous gastrectomy for adenocarcinoma because the incidence of ovarian metastases is quite frequent and influences the prognosis.

[Intestinal occlusion caused by persistent omphalomesenteric duct and Meckel's diverticulum: report of 2 cases].

Two rare cases of mechanical intestinal obstruction due to an omphalomesenteric duct remnant and/or to a Meckel's diverticulum, respectively, are reported. The first case was a 20-year-old man and the second an 87-year-old woman. In contrast with various reports in the literature, our experience demonstrates that this kind of obstruction may also affect elderly female patients in western countries.

["Sequential" treatment: is it the best alternative in cholecysto-choledochal lithiasis?].

Laparoscopic cholecystectomy has become the treatment of choice for patients with symptomatic cholelithiasis. About 10-20% of patients with gallbladder stones may also present associated common bile duct stones. The management of the latter remains controversial because many different surgical strategies are available: laparoscopic treatment (laparoscopic common bile duct exploration), sequential endoscopic and laparoscopic treatment (endoscopic retrograde cholangiopancreatography/endoscopic sphincterotomy [ERCP/ES] prior to laparoscopic cholecystectomy), inverted sequential endoscopic-laparoscopic treatment (laparoscopic cholecystectomy followed by ERCP/ES), and combined endoscopic-laparoscopic treatment (laparoscopic cholecystectomy with intraoperative ERCP/ES).

[Laparoscopy in abdominal emergencies. Indications and limitations].

Laparoscopy, which has been well known as a diagnostic procedure for more than a century, has recently established itself as an important therapeutic procedure in several branches of surgery. In the present study the authors report on 221 patients over a 10-year period (1991-2001), admitted to hospital with a diagnosis of acute abdomen or abdominal trauma. All patients were submitted to emergency laparoscopic surgery; 128 patients (57%) presented acute appendicitis, 40 (18%) acute cholecystitis, 13 (6%) occlusive ileus, 10 (5%) adnexal pathologies, 9 (4%) perforation of abdominal viscera, 3 (1.
