| Abstract |
PURPOSE
The pecten band can be defined as a fibrous tissue on the lowermost part of internal anal sphincter and may cause anal outlet obstruction, but its role is debatable. We evaluated the functional roles of the pecten band in hemorrhoids patients.
METHODS
Three hundred sixteen hemorrhoids patients who underwent operations from January 1998 to April 2003 were analyzed for anal function according to presence or absence of a pecten band by using anorectal manometry and the constipation score.
RESULTS
The numbers of males and females were 167 and 149.
The overall pecten band positive was 63.6% (201/316), and pecten band positive was 84.6% (33/39) in patients who had previous anal surgery while it was 60.6% (168/277) in patients who had no history of surgery (P= 0.002). Pure hemorrhoids patients showed an 18.3% positive rate while patients with hemorrhoids and other conditions, such as anal fissure, fistula, or stricture, showed a 95.7% positive rate (P=0.00). Maximal resting anal pressures (mmHg, Mean+/-SD) and constipation score were 78.9+/-24.7 and 7.88+/-3.8 in the positive group and 67.1+/-22.2 and 4.55+/-2.8 in the negative group (P=0.00, 0.00). Postoperatively, the constipation score decreased significantly from 7.25 to 2.82 (P=0.003).
CONCLUSIONS
The pecten band seems to be associated with anal outlet obstruction, and a pecten band releasing operation may be considered according to its presence or absence. |
