Short- and long-term results of open laparoscopic multisegmental resection and anastomosis for synchronous colorectal cancer located in separate segments.

Background: It remains unclear whether laparoscopic multisegmental resection and anastomosis (LMRA) is safe and advantageous over traditional open multisegmental resection and anastomosis (OMRA) for treating synchronous colorectal cancer (SCRC) located in separate segments.

Aim: To compare the short-term efficacy and long-term prognosis of OMRA as well as LMRA for SCRC located in separate segments.

Methods: Patients with SCRC who underwent surgery between January 2010 and December 2021 at the Cancer Hospital, Chinese Academy of Medical Sciences and the Peking University First Hospital were retrospectively recruited.

Long-term outcomes and failure patterns after laparoscopic intersphincteric resection in ultralow rectal cancers.

Background: Intersphincteric resection (ISR), the ultimate anus-preserving technique for ultralow rectal cancers, is an alternative to abdominoperineal resection (APR). The failure patterns and risk factors for local recurrence and distant metastasis remain controversial and require further investigation.

Aim: To investigate the long-term outcomes and failure patterns after laparoscopic ISR in ultralow rectal cancers.
