RESUMO
Objective:To study the feasibility for transumbilical single-incision laparoscopic appendectomy (SILA) with conventional laparoscopic instruments, and compare SILA with the traditional three-port laparoscopic appendicectomy (LA).Methods:The clinical data of 113 patients with acute appendicitis from January 2018 to August 2020 in the Second Hospital of Jiaxing City were retrospectively analyzed. Among them, 61 patients received traditional three-port LA (three-port LA group), 52 patients received transumbilical SILA (SILA group). The operative time, intra-operative blood loss, surgical complications, length of hospital stay and hospitalization costs were recorded. Pain score 6 h after operation was assessed by visual analogue scale. C-reactive protein (CRP) on the first day after operation was detected. All patients were followed up for 1 month.Results:In 2 groups, all patients did not suffered from the conversion to open operation or multi-port method, massive bleeding and accessory injury during the operation. Moreover, severe pain, severe incision infection, residual abdominal abscess and incisional hernia did not occur. Patients in SILA group had more hidden abdominal scars. there were no statistical differences in operative time, intra-operative blood loss and CRP on the first day after operation between 2 groups ( P>0.05); the rate of moderate pain degree 6 h after operation, length of hospital stay and hospitalization costs in SILA group were significantly lower than those in three-port LA group: 15.38% (8/52) vs. 34.43% (21/61), (3.63 ± 1.22) d vs. (4.31 ± 1.38) d and (8 802 ± 1 466) yuan vs. (9 559 ± 1 617) yuan, and there were statistical differences ( P<0.05 or <0.01). Conclusions:The transumbilical SILA with conventional laparoscopic instruments is safe and feasible, the scar is more difficult to see, the cosmetic effect is much clearer, and the length of hospital stay is shorter.
