[Laparoscopic surgery of the liver, in 92 cases]

We analyze the experience in laparoscopic hepatic surgery of the Research Center of Laparoscopic and Open Surgery from Iaşi between 1993-2006. This study includes 92 patients (0.9% from 10,367 laparoscopic operations) with liver pathology considered for laparoscopic treatment. We performed 42 Lin procedures (wide fenestration technique) for serous hepatic cysts, 32 cystectomies for hepatic hydatid disease, 10 non-anatomical hepatic resections (for 2 adenomas, 4 haemangiomas, 4 metastasis) and 8 steam water thermo-necrosis (for multiple hepatic metastasis). Conversion to open surgery rate was 8.7% (hepatic hydatid cysts--6 cases, serous hepatic cyst--1 case with associated acute cholecystitis, thermo-necrosis--1 case). We had no postoperative mortality and morbidity rate was 6.5%. The follow-up was available in all patients for a mean time of 12 months, by abdominal ultrasound exam and/or computed tomography. No evidence of disease recurrence was registered. We are at the beginning of the laparoscopic hepatic surgery and these results need to be confirmed. For the hepatic serous cysts the laparoscopic fenestration is the best treatment, but for the hepatic hydatid cyst, the laparoscopic approach is indicated only in selected cases: uni-vesicular hydatid cyst, noncomplicated, localised into the "laparoscopic" segments of the liver. Albendazole treatment is also necessary in these cases. For all types of benign liver tumours, the best indication remains small, superficial lesions, located in the anterior or the lateral segments of the liver. When performed by expert liver and laparoscopic surgeons using an adequate surgical technique, the laparoscopic approach is safe for performing minor liver resection for malignant tumours and is accompanied by the usual postoperative benefits of laparoscopic surgery.
