Abstract
Laparoendoscopic single-site surgery (LESS) further minimizes the invasiveness of traditional laparoscopic surgery. However, the "chopstick" effect caused by the parallel arrangement of the instruments in the umbilicus is considered an obstacle indelicate operations. The purpose of this study was to introduce a new technique characterized by a double fulcrum formed by instruments, named the "chopstick" technique, which facilitates the expedient accomplishment of complicated surgeries such as LESS radical hysterectomy (LESS-RH). Seventy-three patients who underwent LESS-RH using the "chopstick" technique were retrospectively analyzed. The procedure was performed successfully in 72 patients. The median operative duration was 225 min, and the median intraoperative blood loss was 200 ml. Among the operations in the first 20 patients, intraoperative vascular injuries and bladder injury occurred in two patients and were repaired by LESS. Patients responded positively regarding minimal postoperative pain control. The score of satisfaction with the cosmetic outcome expressed by the patients was eight at discharge and nine 30 days later. In conclusion, this study presents the feasibility of accomplishing complicated procedures, such as radical hysterectomy, by LESS using the “chopstick” technique. This approach provides more options for both selected patients and surgeons.

The difficulty caused by the parallel arrangement of all instruments in the umbilicus, which is called the "chopstick" effect7, is considered an obstaclein delicate operations
Since 2016, we have explored this new technique for LESS radical hysterectomy with pelvic lymphadenectomy (LESS-RH/PLND)
Summary
Laparoendoscopic single-site surgery (LESS) further minimizes the invasiveness of traditional laparoscopic surgery. The purpose of this study was to introduce a new technique characterized by a double fulcrum formed by instruments, named the "chopstick" technique, which facilitates the expedient accomplishment of complicated surgeries such as LESS radical hysterectomy (LESS-RH). This study presents the feasibility of accomplishing complicated procedures, such as radical hysterectomy, by LESS using the “chopstick” technique. This approach provides more options for both selected patients and surgeons. If a single fulcrum is changed into adouble fulcrum in LESS as when Asians use chopsticks, delicate operations can be performed more efficiently. This technique with a double fulcrum was named the “chopstick" technique. The objectives of this study were to evaluate the feasibility of the “chopstick" technique for use in complicated surgeries and discuss its technical points
