Laparoscopic hepatectomy with the hook blade of ultrasonic coagulating shears and bipolar cautery with a saline irrigation system

Background

The number of patients who have undergone laparoscopic hepatectomy is small, and the operative procedure is not yet well established.

Methods

We performed laparoscopic hepatectomy in eight patients, using the hook blade of ultrasonic coagulating shears, and bipolar cautery with a saline irrigation system, with minilaparotomy. The operative time, blood loss, and postoperative hospital stay of patients with laparoscopic left lateral segmentectomy were compared with these parameters in ten patients who had had a left lateral segmentectomy with laparotomy.

Results

The laparoscopic hepatectomies included seven left lateral segmentectomies and one nonanatomical partial resection of the lateral segment. The mean duration of the operation in these eight patients was 181.1 ± 44.6?min. The mean amount of blood loss was 177.6 ± 129.1?ml. Postoperative complications consisted of two cases of bleeding. The mean postoperative hospital stay in all eight patients was 9.88 ± 4.36 days. The mean duration of operation (185.9 ± 46.0?min) and mean postoperative hospital stay (9.47 ± 4.61 days) in the seven patients with laparoscopic left lateral segmentectomies were significantly shorter than these parameters (255.7 ± 59.4?min and 24.6 ± 8.82 days) in the ten patients who had had left lateral segmentectomies with laparotomy. The mean amount of blood loss (160.0 ± 128.9?ml) in the laparoscopic series was less than that (318.5 ± 192.2 days) in the patients who had had laparotomy.

Conclusions

Laparoscopic hepatectomy with the ultrasonic coagulating shears and bipolar cautery with minilaparotomy was safe, and less invasive than the open procedure, for minor hepatectomy procedures such as left lateral segmentectomy.
