Right hepatectomies without vascular clamping: report of 87 cases.

BACKGROUND/PURPOSE: Portal triad clamping and total or intermittent hepatic vascular exclusion are usually used to reduce blood loss during major liver resections. We report, in this retrospective study, the results of right hepatectomy without vascular clamping. METHODS: From January 1986 to July 2001, 87 right hepatectomies, including 14 extended right hepatectomies, were performed without vascular clamping. There was 53 men and 34 women, with a mean age of 60.2 +/- 12.5 years. Indications were 58 metastases, 16 hepatocellular carcinomas, 5 cholangiocarcinomas, 4 adenomas, 3 angiomas, and 1 carcinoid tumor. All the procedures were carried out using an ultrasonic dissector and intraoperative ultrasonography with only vascular control (looping of the hepatic pedicle and supra; and infrahepatic vena cava). RESULTS: There were four postoperative deaths and 23 complications (26%), including hepatocellular failure (6), pulmonary complications (6), transient bile leakage (5), digestive bleeding (2), subphrenic abscess (1), inferior vena cava (IVC) thrombosis (1), disseminated intravascular coagulation (DIC; 1), and evisceration (1). Forty-two patients (48%) had no blood transfusion. The mean blood transfusion requirement was 1.5 +/- 2.7 units. The mean operative length was 280 +/- 60 min and the mean hospital stay was 12.8 +/- 8.1 days. Liver function test results were similar to those in other studies on days 1, 4, and 7 postoperatively, with a return to normal values after 1 week. CONCLUSIONS: In our experience with major liver resections, vascular clamping is not necessary.

[Prosthetic treatment of bilateral inguinal hernias via laparoscopic approach or Stoppa procedure]. / Traitement prothétique des hernies inguinales bilatérales par voie laparoscopique ou par opération de Stoppa.

AIM OF THE STUDY: The aim of this prospective non-randomized study was to compare Stoppa's technique to laparoscopic approach in totally extraperitoneal repair of bilateral inguinal hernia. PATIENTS AND METHOD: From December 1996 to December 1998, 117 consecutive patients with 234 hernias underwent either Stoppa's technique (74 patients) or a totally extraperitoneal laparoscopic approach (43 patients). Patients were randomized in two groups according to the surgeon to whom they were referred. All patients were reviewed in December 1999. RESULTS: There was no mortality. Complications occurred in 3% of patients after Stoppa's technique (group S) and in 4% of patients in the laparoscopic group (group L). The conversion rate was 7% (3 cases). Postoperative analgesia use, hospital stay, and duration of disability were significantly shorter in group L, the cost was lower, but the operating time was significantly longer than in group S. Recurrence rates were similar in the two groups: 2% in group S, 1.1% in group L. CONCLUSION: The laparoscopic approach appears to be preferable to Stoppa's technique in the treatment of bilateral inguinal hernia.
