Diseases of the colon and rectum

The levator ani has been divided into many functional portions based on necropic observation. Our objective was to use a combination of CT and magnetic resonance images to show a complete levator ani. ⋯ The transverse portion of the levator ani has five kinds of shapes in the different-coronal sections of the pelvis, which changes from basin to dome in a lying position. The puborectalis is outside the vertical portion and not part of the levator ani.

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.

Purulent or fecal peritonitis is one of the most serious complications of acute diverticulitis. Up to one-fourth of patients hospitalized for acute diverticulitis require an emergent operation for a complication, including abscess, peritonitis, or stenosis. Open Hartmann's procedure has been the operation of choice for these patients. The advantages of laparoscopy could be combined with those of the primary resection in selected patients with peritonitis complicating acute diverticulitis. However, because of technical difficulties and the theoretic risk of poorly controlled sepsis, laparoscopic Hartmann's procedure has been seldom reported for such patients. ⋯ The results of this small series demonstrated that the indications of laparoscopy in diverticulitis could be extrapolated to selected patients with peritonitis. The technical feasibility and safety of laparoscopic Hartmann's procedure in selected patients seem acceptable. However, larger-scale, controlled studies are needed to define more accurately the role of laparoscopy in complicated diverticulitis.
