Objective: To investigate the effect of internal and external treatment of traditional Chinese medicine for intra-abdominal abscess postoperative appendicitis. Method: One hundred and twenty-four cases of suppurative appendicitis patients complicated with postoperative abdominal abscess were randomly divided into control group of 60 cases given western medicine routine treatment

and the treatment group of 64 examples given Chinese medicine internal and external treatment. The clinical curative effect

clinical symptoms (the body temperature to restore normal

blood picture back to normal

abscess disappeared

bowel sound recovery

abdominal pain disappear and defecation time

and hospitalization days) in the two groups were compared. And the complications (infection of incision

increase of pelvic abscess

between intestinal abscess

intestinal adhesion) and the recurrence rate were also compared. Result: The total effective rate was 78.4% and 92.2% in the control group and the treatment group accordingly (P<0.05). The normalization time for body temperature was (4.1±0.6)

(2.8±0.9) d

for blood picture (7.8±0.7)

(5.9±0.10) d

for abscess (4.5±0.6)

(2.9±0.9) d

for bowel sound (59.1±1.4)

(38.5±1.7) h

for the first bowel movement (5.6±3.8)

(3.2±3.2) d

for abdominal pain improvement (7.1±3.2)

(4.3±3.0) d and for hospitalization days (8.5

6.7) d in controls and treatment group respectively (P<0.05). The postoperatie infection rate of incision was (13.3%

3.1%)

intestinal adhesion (25.0%

7.8%)

relapse (16.7%

4.7%)in the controls and in the treatment group accordingly (P<0.05). Conclusion: The internal and external treatment of traditional Chinese medicine for intra-abdominal abscess postoperative appendicitis can improve clinical efficient
