Short-term efficacy comparison of totally laparoscopy and open pancreatoduodenectomy in the treatment of periampullary carcinoma

Objective To explore the short-term efficacy of totally laparoscopy pancreatoduodenectomy (TLPD) and open pancreatoduodenectomy (OPD) in the treatment of periampullary carcinoma. Methods The clinical data of 50 patients with periampullary carcinoma in the First Hospital of Shanxi Medical University from June 2016 to March 2019 were retrospectively analyzed. According to the different surgical methods, the patients were divided into TLPD group (22 cases) and OPD group (28 cases). The perioperative and postoperative related indicators between the two groups were compared. Results Both groups had successfully received the operation. The operating time in TLPD group was longer than that in OPD group, and the difference between the two groups was statistically significant [(665±213) min vs. (447±215) min, t = -0.356, P = 0.001]. The amount of intraoperative bleeding in TLPD group was less than that in OPD group, and the difference between the two groups was statistically significant [100 ml (50-325 ml) vs. 300 ml (100-500 ml), Z = -2.230, P = 0.026]. There were no significant differences in the proportion of intraoperative blood transfusion, lymph node dissection number, resected tumor diameter, postoperative diet restriction time, postoperative extubation time, postoperative hospital stay and the incidence of postoperative complication between TLPD group and OPD group (all P > 0.05). Conclusions TLPD and OPD has a similar short-term efficacy in the treatment of periampullary carcinoma. The operating time of TLPD is longer than that of OPD, but TLPD can effectively control the intraoperative bleeding.
