Hand-assisted laparoscopic digestive surgery provides safety and tactile sensation for malignancy or obesity

Some of the persistent problems associated with laparoscopic surgery stem from the inability of the surgeon to palpate the abdominal contents during the operation. This lack of tactile sensation can lead to poor abdominal exploration, difficulty in extracting the organs, and a relatively long operation time compared to conventional procedures. The Dexterity Pneumo Sleeve is a new device that allows the surgeon to insert his or her hand into the abdominal cavity through a small incision while preserving the pneumoperitoneum.

Recently, 13 of our patients underwent hand-assisted advanced laparoscopic surgery using this device. In this series, we had two cases of gastrectomy, two cases of gastric bypass for morbid obesity, two Whipple cases for periampullary tumor, and seven cases of bowel resection. On the basis of this series, we were able to assess the utility of this device.

Satisfactory pneumoperitoneum was maintained in 12 of 13 cases. The length of the skin incision was 7.8 cm on average, which was almost the same size as surgeon's glove. The device proved to be very useful for tissue retraction and abdominal exploration in all cases and for intracorporeal knot tying in some cases.

We found that the device permitted an easier dissection, resection, and anastomosis. It also helped to decrease the operation time.
