Correlation between short-term anal control function and number of pacinian corpuscles in patients undergoing procedure for prolapse and hemorrhoids or Milligan-Morgan hemorrhoidectomy

AIM: To analyze the relevance between pathological damage and clinical complications of Milligan-Morgan hemorrhoidectomy and procedure for prolapse and hemorrhoids (PPH).

METHODS: Clinical data for 90 patients who were operated at Suzhou Hospital of Traditional Chinese Medicine, the Third Affiliated Hospital of He'nan College of Traditional Chinese Medicine and Affiliated Hospital of Nanjing University of TCM from June 2013 to June 2014 were retrospectively. The patients were divided into two groups, patients undergoing Milligan-Morgan hemorrhoidectomy and those undergoing PPH. Anal control function was assessed in both groups. All of surgical specimens underwent Alcian blue staining to count the number of pacinian corpuscles. Then the relevance between the pathological damage and clinical complications was analyzed.

RESULTS: The short-term anal control function had no statistically significant difference between the two groups. The number of pacinian corpuscles in resected tissue differed significantly between the PPH and Milligan-Morgan groups (P < 0.05). Compared with the Milligan-Morgan group, the number of pacinian corpuscles significantly increased in the PPH group (11.3 ± 6.11 vs 42.7 ± 9.86, P < 0.05). There was a positive correlation between anal control function and the number of Pacinian corpuscles.

CONCLUSION: The short-term anal control function had a significant difference between patients undergoing PPH and those undergoing traditional hemorrhoid surgery. The number of pacinian corpuscles was significantly higher in the PPH group than in the traditional hemorrhoid surgery group, which may be the reason why the short-term anal control function in the PPH group was inferior to that of the traditional hemorrhoid surgery group.
