There were no significant differences between the two groups in the rates of intra-peritoneal abscess or wound infection .
It is not clear whether routine abdominal drainage has any effect on the prevention of intra-peritoneal abscess after open appendectomy for complicated appendicitis .
Abdominal drainage after an emergency open appendectomy may be associated with delayed hospital discharge for patients with complicated appendicitis
BACKGROUND Appendectomy , the surgical removal of the appendix , is performed primarily for acute appendicitis .
Patients who undergo appendectomy for complicated appendicitis , defined as gangrenous or perforated appendicitis , are more likely to suffer from postoperative complications .
The routine use of abdominal drainage to reduce postoperative complications after appendectomy for complicated appendicitis is controversial .
OBJECTIVES To assess the safety and efficacy of abdominal drainage to prevent intra-peritoneal abscess after open appendectomy for complicated appendicitis .
Abdominal Drainage Following Appendectomy and Cholecystectomy
Consecutive patients undergoing emergency appendectomy ( 283 ) or urgent cholecystectomy ( 51 ) were prospect ively studied for the development of postoperative incisional or peritoneal sepsis . Severity of the original peritoneal infection was carefully recorded , while use of a Penrose dam to drain the peritoneum was r and omized according to pre-assigned hospital number . Both aerobic and anaerobic cultures were taken from the abdomen at the time of operation as well as from all postoperative infectious foci . Results demonstrated no essential differences in incidence of wound and peritoneal infection following  appendectomy  for simple or suppurative appendicitis ( 187 ) or following  cholecystectomy  for acute cholecystitis ( 51 ) . However , with gangrenous or perforative appendicitis ( 94 ) , incisional and intra-abdominal infection rates were 43 % and 45 % , respectively , when a drain was used ; yet only 29 and 13 % , respectively , without a drain . These latter differences were significant ( p < 0.001 ) . In addition , intra-abdominal abscesses were three times as likely to drain through the incision than along any tract provided by the rubber conduit . Cultures revealed that hospital pathogens accounted for a greater proportion of wound and peritoneal sepsis after cholecystectomy and appendectomy for simple or suppurative appendicitis if a drain had been inserted than if managed otherwise . By contrast , a mixed bacterial flora was responsible for most infections following appendectomy for gangrenous or perforated appendicitis , irrespective as to use of a drain
