To investigate the safety and effectiveness of ultra minimally invasive surgical instruments in laparoscopic sleeve gastrectomy (LSG).

All112 patients with random prevention data who underwent LSG in our hospital from July 2018 to August 2022 were included. Among them, 51 patients underwent 4-hole LSG, 29 patients underwent 3-hole LSG, and 32 patients underwent ultraminimally invasive laparoscopic sleeve gastrectomy (ULSG). The differences of the three groups (4-hole LSG group, 3-hole LSG group, ULSG group) in operation time, bleeding volume and pain score were comprared.

Compared with the 3-hole LSG group, the ULSG group had significantly reduced bleeding volume and operation time (P<0.05). There was no significant difference between 4-hole LSG group and ULSG group in the amount of bleeding and operation time (P>0.05). Compared with the 4-hole LSG group, at 6h and 12h, the pain scores of the ULSG group decreased significantly (P<0.05). There was no significant difference in pain scores between the 3-hole LSG group and the ULSG group (P>0.05). There was no significant difference in the incidence of complications (stomach leakage, gastric stenosis, postoperative nausea and vomiting, pulmonary infection, thrombosis) among ULSG group, 4-hole LSG group and 3-hole LSG group (P>0.05).

The ULSG takes into account the advantages of beautiful skin, convenient operation and safe operation. The ULSG can better expose the visual field and cut gastric tissue by using the methods of picking, blocking and pulling.
