Single-port laparoscopic appendectomy for perforated appendicitis using ArtiSential® wristed articulated instrument.

Single-port laparoscopic appendectomy (SPLA) was firstly introduced in 1998 and has been suggested potential advantages including better cosmetic outcome, less post-operative pain and avoidance of possible haemorrhagic complications from injuring epigastric vessels. However, single-port laparoscopic approach using conventional straight instruments may lead to internal and external conflicts and ergonomic discomfort, and new laparoscopic articulating instruments were developed to overcome these limitations of straight instruments. The ArtiSential (LIVSMED Inc., Republic of Korea) is an 8-mm diameter pistol-handle instrument that has complete articulating function like human wrist and intuitive controllability. We present a technical report of SPLA for perforated appendicitis using ArtiSential wristed articulated instrument. A 78-year-old female with a body mass index of 23.5 was referred to our emergency room with right lower quadrant abdominal pain. Abdominal computed tomography scan showed a distended tubular structure in the right lower quadrant (1.2 cm in diameter) with periappendiceal fluid collection. The patient's clinical presentation was highly indicative of perforated acute appendicitis. We performed SPLA with ArtiSential grasper with the left hand, and this instrument helped us to allow greater manoeuvrability and dexterity with double triangulation technique. The total operation time was 40 min, and the patient was discharged without complications on the 1 day after surgery.
