Short- and long-term outcomes of laparoscopic low anterior resection with “dog ear” invagination anastomosis for mid and distal rectal cancer a propensity score matched analysis

HIGHLIGHTS

SUMMARY

The authors designed a single-center and propensity score-matched analysis to investigate the shortterm and long-term outcomes of patients with rectal cancers by comparing "dog ear" invagination anastomosis (LLAR + DAIA) to double-stapled technique (LLAR + DST). In the matched cohort, in the LLAR + DST group, 3- year and 5-year disease-free survival rates were 79.2 and 63.7% respectively and they were 76.5 and 67.2% respectively in the LLAR + DAIA group. When the LARS score was calculated and categorized into groups of "no", "minor," or "major LARS", the . . .
