Abstract
Background and aims
Low anterior resection and abdominoperineal resection with total mesorectal excision are the standard treatment in patients with low rectal cancer. Rectal resection remains a surgical intervention with considerable morbidity and long-term impairment of quality of life. Local excision of low rectal cancer is regarded as an alternative to radical surgery; however, occurrence of lymph node metastasis even in patients with highly differentiated early-stage rectal cancer may be underestimated.
Patients and results
In two patients with T1 rectal cancer, minimal-invasive partial excision of the mesorectum was performed after transanal excision of the tumor. The postoperative course was uneventful in both patients. Patients left the hospital on the fourth and fifth postoperative day without any complaints. In one patient, histo-pathological workup revealed a lymph node metastasis in the specimen.
Discussion
The technique of “Endoscopic posterior mesorectal resection” represents an interesting option in the surgical treatment of rectal cancer, as it allows for the first time an organ preserving resection of local lymph nodes in the small pelvis. It may evolve as an efficient new staging procedure to identify patients with metastatic disease who may benefit from multimodal treatment or extended surgery.
