Abstract:

The author's team frequently confronted issues like insufficient exposure and timeconsuming drawdown adjustment during single-hole laparoscopic surgery.Recently， we independently developed a type of ultramicroscopic instrument to assist single-hole laparoscopic surgery， encompassing single-hole laparoscopic cholecystectomy， single-hole laparoscopic appendectomy， and single-hole hemihepatectomy.Compared with conventional single-hole laparoscopic hepatectomy， merely one or two 2mm auxiliary traction holes are added， and no scar is left upon the healing of the auxiliary holes.The postoperative cosmetic outcome is comparable to that of conventional single-hole laparoscopic hepatectomy， and even the umbilical incision is smaller.With the assistance of the instrument， the operational difficulty can be mitigated，and the exposure effect is more pronounced.This video mainly presents the clinical application of this 2mm ultramicroscopic instrument in single-hole laparoscopic partial splenectomy， which is an auxiliary instrument worthy of promotion.
