Impact of Two‐Team Surgery on Short‐ and Long‐Term Outcomes of Transanal Total Mesorectal Excision for Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
This study investigated the impact of two‐team surgery on short‐ and long‐term outcomes of transanal total mesorectal excision for rectal cancer. Two‐team surgery has some advantages over one‐team surgery, such as shorter operation time, decreased estimated blood loss, increased number of lymph nodes dissected, and decreased positive distal margin ...
