Comparing the short-term results of the improved triangular anastomosis technique for complete laparoscopic radical resection of sigmoid colon cancer and laparoscopic-assisted small incision colon reconstruction: A CONSORT study

The laparoscopic approaches using the triangular anastomosis technique for sigmoid colon cancer (SCC) are rare. This CONSORT study explored the short-term effects of laparoscopic radical resection of SCC with modified triangular anastomosis technique and laparoscopic-assisted small incision colon cancer reconstruction surgery. From April 2019 to January 2021, a total of 86 patients with SCC who were admitted to Luopu County People’s Hospital were selected and received radical resection. Patients were divided into 2 groups using a random number table method: in the control group, patients underwent laparoscopic-assisted small-incision reconstruction surgery, and patients in the observation group underwent complete laparoscopic surgery with modified triangular anastomosis technique. The 2 groups were compared in perioperative related indicators and postoperative complications. After 3 months follow-up, local tumor recurrence and metastasis, abdominal wall puncture and implantation, and death were observed. Compared to the control group, shorter operation time, gastrointestinal reconstruction time, postoperative exhaust time, hospitalization time, and less intraoperative blood loss, and lower probability of complications were observed in the observation group (P < .05). However, there was no significant difference in the number of lymph node dissections between the 2 groups (P > .05). After 3 months of follow-up, no local tumor recurrence, distant tumor metastasis, abdominal wall puncture implantation, and death were found in the 2 groups of patients. It is indicated that the improved triangular anastomosis technique for complete laparoscopic radical resection of SCC is effective in treatment for SCC.
