[Krukenberg tumour: diagnostic findings and surgical therapy. Recent acquisitions]. / Tumore di Krukenberg: riscontro diagnostico e terapia chirurgica. Recenti acquisizioni.

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. The Authors do not consider a bilateral preventive ovariectomy associated with gastrectomy as advisable in premenopausal patients, because the studies to date are inadequate for the purposes of drawing conclusions regarding the benefit of these procedures. They consider a more valid policy to be a thorough follow-up in women with a previous gastrectomy for adenocarcinoma because the priority must be accorded to diagnosing secondary lesions so as to be able to perform an ovariectomy which may improve the prognosis. With this in mind it is important to assess Ca 19.9 and perform radiological procedures, such as CT and MRI. The prognosis may be distinctly unfavourable as in one of the cases reported by the Authors involving a very rare form of secondary lesion of the bone marrow and consequent medullary aplasia, with the onset of severe haemorrhages in several areas leading to the patient's death. They consider that surgical treatment should be preceded by a diagnostic laparoscopy. When there are other concomitant negative prognostic factors such as neoplastic ascites and perineal carcinosis, ovariectomy will prove ineffective from the prognostic point of view.

[Intestinal occlusion caused by persistent omphalomesenteric duct and Meckel's diverticulum: report of 2 cases]. / Occlusioni intestinali da persistenza del dotto onfalo-mesenterico e diverticolo di Meckel: presentazione di due casi.

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. Both patients showed signs and symptoms of intestinal obstruction and were operated on as emergencies. A complete diagnosis was possible only at operation and early surgery was important to prevent strangulation and gangrene of the bowel. The authors conclude that prompt and appropriate surgical treatment reduces the mortality risk in all patients with intestinal obstruction, including even resected cases.

["Sequential" treatment: is it the best alternative in cholecysto-choledochal lithiasis?]. / Il trattamento "sequenziale": la migliore delle alternative nella litiasi colecisto-coledocica?

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). The aim of this study was to evaluate the efficacy and safety of sequential endoscopic-laparoscopic treatment in patients with cholecystocholedocholithiasis. We retrospectively analyzed the clinical, biochemical and radiological features of 552 patients operated on for cholelithiasis from 1991 to 2001. Common bile duct stones were suspected on the basis of increased serum levels of bilirubin, GOT, GPT, GGT, alkaline phosphatase; presence of jaundice; history of pancreatitis or cholangitis; dilated common bile duct (diameter > 8 mm) or common bile duct stones at hepatobiliary ultrasonography; presence of common bile duct stones at MR-cholangiography or at i.v. cholangiography. In patients with suspected common bile duct stones, preoperative ERCP was performed; if common bile duct stones were confirmed, ES was performed. When common bile duct stones were not suspected preoperatively, laparoscopic cholecystectomy was performed directly. Overall morbidity, mortality and conversion rates in the two groups were evaluated. Of 552 patients admitted for cholelithiasis, 62 (11.3%) underwent preoperative ERCP for suspected common bile duct stones. In 41 patients (66.1%) common bile duct stones were identified and ES with common bile duct stone extraction was performed in 40 patients (clearance: 97.5%). The overall morbidity was 16% (10 cases of post-ERCP acute pancreatitis); no mortality occurred. The conversion rate during subsequent laparoscopic cholecystectomy was 4.8%. In the group of patients with no suspicion of common bile duct stones, the conversion rate was 4.9%. Sequential treatment cannot be considered the best approach for patients with cholecystocholedocholithiasis because of its morbidity rate and the high rate of negative preoperative ERCP findings. Combined endoscopic-laparoscopic treatment seems to present more advantages, especially in term of morbidity, hospital stay and patient compliance and may, in future, be considered the treatment of choice for patients with cholecystocholedocholithiasis.

[Laparoscopy in abdominal emergencies. Indications and limitations]. / La laparoscopia nelle urgenze addominali. Indicazioni e limiti.

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 (1.4%) acute diverticulitis, 3 (1.4%) subdiaphragmatic abscesses, 3 (1.4%) intestinal infarction, 2 (0.8%) other diseases and 10 (5%) abdominal trauma. The operation was completed laparoscopically in 192 cases (87%), while conversion to laparotomy proved necessary in 29 cases (13%). The morbidity of the cases completed laparoscopically was 3%, the mortality 0.5%, and the mean hospital stay 4 days. Advantages of laparoscopy (shorter hospital stay, rapid postoperative recovery and faster return to social activities) emerge from the present study and are confirmed by the literature. The possibility of combining a diagnostic procedure with curative therapy suggests that laparoscopy may have an important role in emergency surgery, demonstrating its efficacy also in acute abdominal syndromes. Nevertheless, emergency laparoscopic surgery is still a technically difficult procedure that needs to be performed by an expert surgical team.
