NOTES: new dimension of minimally invasive surgery.

Natural orifice transluminal endoscopic surgery (NOTES) is an emerging experimental alternative to conventional surgery. NOTES eliminates abdominal incisions and incision-related complications by combining endoscopic and laparoscopic techniques to diagnose and treat abdominal pathology.

[Comparing the influencing factors of anastomotic bleeding in rectal carcinoma resection between laparoscopic and open radical approaches].

Objective: To observe the occurrence of anastomotic bleeding following laparoscopic and open radical resection for rectal carcinoma, and to explore its contributing factors.

Methods: Two hundred and sixty-three cases of rectal carcinoma undergone radical resection were divided into 2 groups, laparoscopic surgery (LS) group (n=86) and open surgery (OS) group (n=177). According to the different locations of anastomotic stoma and with or without preventive colostomy, the two groups were divided into AR sub-group and LAR/UAR sub-group, colostomy sub-group and non-colostomy sub-group.
