[Postoperative pain of hemorrhoid treated with thread embedding at Changqiang (GV 1)]

To compare the therapeutic effect of postoperative pain of hemorrhoid treated with thread embedding at Changqiang (GV 1) and Indometacin suppository.

Eighty cases were randomly divided into an acupoint catgut-embedding group (group A) and an Indometacin group (group B), forty case in each group. In group A, thread embedding at Changqiang (GV 1) was applied, and Indometacin suppository was put into rectum in group B. The pain intensity after 6, 12, 24, 72 hours of treatment and the the maximum scores of VAS in 24 hours (T24max VAS) of 1-3 days of postopration were evaluated with pain Visual Analogue Scale (VAS); the quantity demanded of analgesic and the adverse reaction were observed.

The scores of VAS after 6, 12, 24, 72 hours of treatment in group A were obviously lower than those in group B (all P < 0.05); the T24max VAS scores in group A were obviously lower than those in group B (all P < 0.05). Six cases in group A and 14 cases in group B were treated with non-steroidal anti-inflammatory drug as well. The total effective rate of 87.5% (35/40) in group A was superior to that of 62.5% (25/40) in group B, indicating the statistically significant differences between two groups (P < 0.05). There was no obvious adverse reaction in group A; in group B, headache, dizziness, nausea, vomiting, distention of chest and palpitation appeared, accounting for 11 cases.
