Single Incision Laparoscopic Splenectomy (SILS)

Laparoscopic splenectomy is widely applied in clinical practice currently [1]. However, the operative technique and key points of single incision laparoscopic splenectomy (SILS) are different from those of laparoscopic splenectomy. Meanwhile, the spleen has abundant vascularity and brittle texture and is vulnerable to hemorrhage, which leads to difficulties in operation [2]. In 2009, Barbaros [3] firstly reported successful SILS in two patients with immune thrombocytopenic purpura (ITP). Since then, some scholars have reported cases of successful use of SILS for splenic diseases successively [4, 5]. In 2011, Second Department of General Surgery, Shengjing Hospital, Affiliated to China Medical University completed the first case of SILS for traumatic splenic rupture in the world [6]; in 2020, it performed transumbilical SILS combined with esophagogastric fundus pericardial vasectomy for cirrhotic portal hypertension and reported this operation on international journal firstly [7]. In 2013, Fan Ying et al. conducted a systematic meta-analysis and drew a conclusion that SILS has much more viability and safety compared with multi-incision laparoscopic splenectomy, with a better cosmetic result [8]. With the development of laparoscope and its technology, there is an increase in articles reporting SILS.
