Laparoscopic surgical treatment of perforated duodenal ulcer.

Perforation of peptic ulcer is a surgical emergency which still carries a risk of mortality. The main risk factors are delayed diagnosis > 24 hours, ASA-III or ASA-IV, age over 70 years, and associated cardiorespiratory pathologies. There is no unanimous consensus regarding the gold standard treatment of such complications. In this study we report our experience and analyse the literature with the aim of assessing the possible advantages of laparoscopic treatment of perforated duodenal ulcers versus open surgery. From April 2003 to December 2008, 39 patients underwent laparoscopic repair and 7 patients open repair of perforated duodenal ulcer. The following parameters were evaluated in all patients: operative time, duration of hospital stay, time to intestinal canalisation, morbidity and mortality. The conversion rate, in laparoscopic treated patients, was 0%. The mean operative time was longer in the laparoscopic group than in the open group (76.15 +/- 9.49 vs. 63.57 +/- 15.19 minutes; Mann Whitney test p < 0.05). The laparoscopic cases had a shorter mean hospital stay than the open cases (5.8 +/- 1.02 vs. 7.8 +/-1.34 days; Mann Whitney test p < 0.001). The time to canalisation in the two groups of patients was similar. One patient (2.56%) in the laparoscopic group and two (28.57%) in the open repair group presented morbidity in the postoperative period. One patient (ASA IV) in the open group died. Laparoscopic treatment in the emergency setting is a safe, reliable procedure, affording all the advantages of the minimally invasive approach.

Ultrasound-guided percutaneous treatment of abdominal collections.

Abdominal abscess is a very important problem nowadays, being responsible for prolonged hospitalisation, because these infections still cause substantial morbidity and mortality. For many years, surgical drainage has been considered the best therapeutic option in abdominal abscesses but several studies have subsequently shown that the percutaneous approach is as effective as surgical drainage. Starting from this background, the aim of this study was to evaluate whether or not percutaneous drainage is a valid treatment of choice. In the Department of Surgical Sciences, Organ Transplantation and Advanced Technologies of the University of Catania, 451 ultrasound guided percutaneous drainages of intra-abdominal abscesses were performed on 430 patients. Abscess drainage was successful in 322/403 (80%) of postoperative abscess, in 16/18 (90%) of primitive abscesses, in 10/12 cases (85%) of acute cholecystitis, in 3/6 cases (50%) of intrahepatic abscess and in 12/12 cases (100%) of pyelonephritis. US-guided drainage is currently the gold standard in the treatment of simple abdominal abscesses.

Anastomotic dehiscence after gastrectomy for cancer. Personal series.

BACKGROUND/AIMS: Nowadays the risk of anastomotic dehiscence after gastrectomy still exists. So the aim of this study was to analyze our experience regarding these anastomoses. METHODOLOGY: In our Surgical Unit, which is located in the Department of Surgical Sciences, Organ Transplantation and Advanced Technologies of the University of Catania, from January 1st 1985 to December 31st 2000, 249 patients underwent surgery for gastric cancer. RESULTS: We observed a statistically significant decrease of leaks in the third period of our study. CONCLUSIONS: These data demonstrate a significant decrease of anastomotic leaks with stapler in comparison to manual anastomoses.

Thermic ablation with RF of liver metastases from colorectal cancer.

Aim of this study was to evaluate the role of radiofrequency ablation in the treatment of the hepatic metastasis of colorectal cancer. From November 1997 to July 2002 49 radiofrequency ablations have been performed in 19 patients (11 male and 8 female; mean age 65 years: range 50-78 years). The disease-free period was between 5 and 32 months. Nodules had a diameter <3 cm in 4 cases while in 3 cases a single lesion was present. One patient had a single lesion after 2 courses of intravenous systemic chemotherapy which had a reduced greater lesion (from 6 to 3 cm) while a 2 cm lesion had disappeared. In the remaining 12 patients the mean number of lesions is 3 (range 1-13) with a diameter between 3 and 12 cm. The radiofrequency ablation has been performed during laparotomy and vascular exclusion through clampage of the liver hilum in 4 cases and percutaneously under ultrasound guide in the remaining 15 cases. All patients underwent follow up by computed tomography, CEA level and ultrasound every 3 months. One patient only has completed a 4 year follow up and is alive without local recurrence but with a cerebral metastasis. The other 18 patients have a 32 months follow up with a survival of 50% (9 on 18). In conclusion in our experience the radiofrequency ablation is a valid alternative method in the treatment of the hepatic metastasis of colorectal cancer.
