Hand-assisted laparoscopic surgery: an emerging technique.

BACKGROUND: Some surgeons are finding that the placement of one hand in the abdomen during laparoscopic procedures returns tactile feedback lost during purely laparoscopic surgery and facilitates dissection, retraction, and control of bleeding. Studies comparing patient postoperative discomfort after laparoscopic and hand-assisted laparoscopic procedures have not found a significant difference.
METHODS: This article is a review of the current literature on hand-assisted laparoscopic surgery and of the different hand-assisted devices on the market. Included in the review are opinions of expert laparoscopic surgeons who have used hand-assisted devices.
RESULTS: More than 100 hand-assisted laparoscopic procedures have been described in the literature. At least four different companies are involved in hand-assisted laparoscopic devices. Three of these companies currently are Food and Drug Administration (FDA) approved in the United States.
CONCLUSIONS: Hand-assisted laparoscopic surgery is not necessary for all laparoscopic procedures. Hand-assisted laparoscopic technique is advantageous for certain procedures and clinical situations such as en bloc resections and removal of solid organ tumors, large colon tumors, and the kidney after donor nephrectomy. This technique offers benefits when a large incision is necessary to complete surgery such an open colon anastomosis.
