Primary Outcome Measures:
  • Evidence of early clinical infection, hematoma, seroma or recurrence confirmed by ultrasonography or/and laboratory findings. [ Time Frame: 30 days ]

Estimated Enrollment: 380
Study Start Date: May 2007
Estimated Study Completion Date: January 2016
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Rives-Stoppa repair of incisional hernia
No drain Procedure: Prosthetic repair of abdominal incisional hernia
Rives-Stoppa repair of incisional hernia

Detailed Description:

Between 3 to 20% of patients who received a midline laparotomy will develop an incisional hernia.

Primary suture of the defect is associated with a recurrence rate between 25 and 50%.Mesh repair is superior with regard to the recurrence (12-20%), but early postoperative complications include infections, hematomas and seromas.

Some advocate the use of drains in order to diminish secretions and complications. Other claim that drains increase the complication's rate.

In the absence of a randomized controlled trial it's not clear whether drainage could influence positively or negatively the occurence of such complications when performing a prosthetic repair of abdominal incisional hernia.

The aim of this study is to answer this question, comparing prospectively two groups of operated patients: the former with drainage and the latter without.
