title: Comparative outcomes of trocar puncture with sump drain, percutaneous drainage, and surgical drainage in the management of intra-abdominal abscesses in Crohn's disease.
abstract: BACKGROUND
  Intra-abdominal abscess is a common complication in Crohn's disease (CD). Traditional percutaneous catheter drainage (PCD) and surgical intervention could not obtain satisfactory results in some cases. We herein demonstrate a novel management option and compare it with traditional strategies.
  
  
  METHODS
  A total of 77 patients were retrospectively collected into 3 groups. Postoperative complication, postoperative recurrence of abscess, subsequent surgery, ultimate stoma creation rate, and survival rate were analyzed.
  
  
  RESULTS
  Patients were divided into the trocar group (n = 21), PCD group (n = 25), and surgery group (n = 31). The incidences of postoperative complication as well as the incidence of recurrent abscess were lowest in trocar group, and ultimate stoma creation rate was highest in the surgery group. Subsequent surgery after initial intervention and survival rate during the follow-up period were similar among the 3 groups.
  
  
  CONCLUSIONS
  Trocar puncture with sump drain had lower incidence of postoperative complication, postoperative recurrence of abscess, and ultimate stoma creation compared with conventional PCD and surgical interventions. This novel technique might be an optimal option in the management of intra-abdominal abscesses in CD.
