Placement of a transanal tube is effective in decreasing the rate of anastomotic leakage after anterior resection using the double stapling technique. However, complications associated with a transanal tube should be carefully considered.

Chylous ascites after colorectal cancer surgery occurred at an incidence of 1.0%, but was significantly more frequent after surgery for tumors fed by the superior mesenteric artery and after D3 lymph node dissection. Conservative treatment was effective in all cases.

We identified the high-risk population for AL after laparoscopic low anterior resection with double stapling technique reconstruction based on two factors. This will enable surgeons to appropriately recommend diverting stoma creation.

PFR improved several clinical symptoms of patients after ISR. Compared with patients after LAR, patients after ISR showed an insufficient response to PFR in improving fecal incontinence. Considering the result of the generalized assessment of the quality of life scale, PFR may offer a therapeutic effect for several symptoms of patients after ISR.

A laparoscopic procedure should be considered for palliative resection of the primary tumor for incurable stage IV colorectal cancer, because the results of this study indicate that the procedure is safe and effective.
