To explore the short and mid-term efficacy of three approaches (lateral/middle/caudal) in the treatment of right hemicolon carcinoma.

A retrospective analysis of the clinical data of 113 patients who underwent laparoscopic right hemicolectomy from May 2016 to May 2019 was divided into three groups according to the different surgical approaches, the lateral approach group (38 cases), intermediate group(36 cases) and caudal approach group (39 cases). SPSS 18.0 statistical software was used to analysis. The number of lymph node dissections and perioperative-related indicators were expressed as(±s), and F test was used. Statistical data of complications and survival rate were tested by χ² test. Kaplan-meier test was used for survival analysis. P<0.05 difference was statistically significant.

The operation time, blood loss and the time of postoperative exhaust time in the three groups were compared with that of the middle group > the lateral group >the caudal group, with statistical significance (P<0.05). There were no significant differences in extubation time, hospitalization time, conversion rate, number of lymph node dissection and conversion to laparotomy rate among the three groups (P>0.05) . The incidences of complications in middle group, lateral group and caudal group were 22.2% , 15.8% and 7.7% respectively, there was no significant difference (P>0.05) . The 1-year survival rate (91.6% , 89.4% , 92.3%) , 3-year survival rate (55.5% , 57.8% , 58.9%) and median survival period(41.7±6.1) months, (42.1±5.6) months, (42.3±5.3) months had no significant difference (P>0.05).

laparoscopic caudal approach can shorten operation time, exhaust time, reduce bleeding and reduce trauma.
