Hand-assisted laparoscopic surgery - An overview

Background: Advanced laparoscopic surgery is complex and time-consuming. Ac hieving consistent efficacy and safety throughout the entire procedure is a lways a problem. For this reason, hand-assisted laparoscopic surgery (HALS) was developed. Methods: Devices were designed to allow manual access to the abdomen throug h the utility laparotomy. By using one hand in the abdomen during laparosco py, the surgeon regains direct tactile sensation and acquires improved hand -eye coordination. The safety of the individual devices has been tested in RCT for the registration of the individual devices. An index known as Surgi cal Action Efficiency was calculated for in six patients undergoing laparos copic colon resection and six patients with hand-assisted colon resections. Results: All of the registered devices are safe. Surgical Action Efficiency for the laparoscopy, group was 55 +/- 14%; for the HALS group, it was 71 /- 4%. This result is statistically significant (p < 0.05). Conclusion: HALS is a safe and efficient method by which it is possible to combine the established convenience and safety of open surgery with the adv antages of minimally invasive surgery.
