To explore the selection of digestive tract reconstruction methods in the treatment of right colon cancer by complete laparoscopic resection.

The data of 89 patients with right colon cancer from October 2018 to November 2019 were retrospectively analyzed. According to the different methods of intraoperative digestive tract reconstruction, the patients were divided into modified group (43 cases) and overlapping group (46 cases). The modified group used modified triangular anastomosis for digestive tract reconstruction, while the overlapping group used overlapping triangular anastomosis for digestive tract reconstruction. SPSS 23.0 software was used for statistical analysis. The surgically-related indicators, quality of life and prognostic nutrition index in accordance with the normal distribution are represented by (±s), and independent sample t test was used. Complications and other enumeration data were compared using χ² test. P<0.05 was considered statistically significant.

Compared with the modified group, the intraoperative blood loss, the length of hospitalization, and the total postoperative complication rate in the overlapping group were not significantly different (P>0.05). The anastomosis time, operation time and the first postoperative exhaust time in overlapping group were shorter than those in modified group (P< 0.05). There was no significant difference in gastrointestinal quality of life (GIQLI) and prognostic nutrition index (PNI) between the two groups 6 months after surgery (P>0.05).

The overlapping triangular anastomosis method can effectively shorten the anastomosis time and operation time in complete laparoscopic resection of right colon cancer, which helps to reduce the operation risk, but it has no obvious advantages in reducing complications and improving prognosis.
