Diseases of the colon and rectum

This study was designed to compare laparoscopic vs. open total mesorectal excision for cancer of the rectum on perioperative outcome and quality of life. ⋯ Laparoscopic total mesorectal excision is safe and feasible, does not jeopardize the complication rate, and has the benefits of much less blood during the operation and shorter hospitalization.

Pilonidal sinus is a disease that does not have a standardized surgical treatment method. This study was designed to compare the outcomes of Limberg fasciocutaneous transposition and V-Y fasciocutaneous advancement flaps in the treatment of patients with pilonidal sinus. ⋯ We conclude that, if the defect is to be reconstructed with a flap in pilonidal sinus cases, reconstruction with Limberg flap should be preferred over reconstruction with V-Y flap because of its lower rate of recurrence.

This study was designed to evaluate one institution's experience with treatment outcomes for rectal squamous-cell carcinoma. ⋯ Our data suggest that most patients treated with upfront chemoradiation therapy followed by surgery did well. Sphincter-preserving surgery is usually feasible. Clinical judgment of tumor response after chemoradiation is not completely reliable. Immunohistochemistry suggests a common cellular origin for rectal squamous-cell carcinoma and rectal adenocarcinoma, which is different from anal squamous-cell carcinoma.
