Hand-Assisted Laparoscopic Technique May Reduce Surgery Time in Colon Cancer: New Study Is Underway

NEW YORK—In patients with colorectal cancer, a 'hand-in' approach to laparoscopic surgery—hand-assisted laparoscopic surgery (HALS)—may yield benefits beyond those of traditional laparoscopic techniques, particularly reduced operation time. Patient recruitment to a study assessing HALS vs standard laparoscopic surgery has begun at several sites in New York City.

In a HALS procedure, the surgeon inserts his or her nondominant hand through the hand-assist device and into the intra-abdominal cavity via an incision between 3 and 5 inches in length, and can operate on the patient in conjunction with standard laparoscopic devices held in the dominant hand.

More Rapid Recovery

Similar to advantages of standard laparoscopy over open surgery, HALS has typically been associated with shorter hospital stays, reduced pain, and more rapid recovery, owing in part to the smaller incision required. HALS also has been reported to improve surgical outcome because the intra-abdominal hand provides the surgeon with tactile sensation and 3D spatial orientation, and permits effective and rapid hemostasis. Reports in the literature also suggest the technique can be learned more quickly than standard laparoscopy, with better reproducibility.

GelPort: Newer HALS Device

The second-generation HALS device that will be studied is GelPort (see Figure), made from a soft, gel-like material that maintains an airtight seal around the surgeon's hand while the sleeve and ring apparatus "creates a kind of doorway to the patient's abdomen," explained investigator Jeffrey W. Milsom, MD, DeCosse Distinguished Professor of Surgery and chief of Colon and Rectal Surgery, Weill Medical College of Cornell University.

The GelPort device is inserted through a small pubic-area incision, with the patient under general anesthesia, Dr. Milsom told ONI.

Manufactured by Applied Medical Resources Corporation, of Rancho Santa Margarita, California, the GelPort system consists of a rubber sleeve (wound protector) that passes through the abdominal wall and is attached at one end to a plastic ring, which rests on the outer surface of the patient's skin. An outer gel dome with a central opening is fitted onto the plastic ring, completing the seal.
