Background: Intra-abdominal abscess (IAA) is a common complication in Crohn’s disease (CD). Traditional percutaneous catheter drainage (PCD) and surgical intervention could not obtain satisfactory results in a certain number of cases.

Hypothesis: We herein demonstrated a novel strategies (trocar puncture with sump drain) for the management of IAA in CD, and compared it with traditional PCD and surgical options.

Methods: 77 patients were collected into three groups. Postoperative complication, postoperative recurrence of abscess, subsequent surgery, ultimate stoma creation rate and survival rate were analyzed. Potential risk factors that correlate with postoperative complication, recurrence of abscess and ultimate stoma creation were analyzed as well.

Results: Patients were divided into trocar (n=21), PCD (n=25) and surgery group (n=31). Incidence of postoperative complication (0/21 vs. 6/25, 8/31), incidence of recurrent abscess (6/21 vs. 16/25, 18/31) and ultimate stoma creation rate (2/21 vs. 5/25, 18/31) were all lowest with statistical significance in trocar group. Subsequent surgery rate (10/21 vs. 17/25, 22/31) and survival rate (0/21 vs. 0/25, 2/31) were also lowest in trocar group as well, but without statistical differences. Drainage strategy was confirmed as a risk factor of postoperative complication and recurrence of abscess in the management of IAA in CD.

Conclusions: This novel technique might be an optimal option in the management of IAA in CD.
