Comparative Study Matching Intraperitoneal Onlay Mesh (IPOM) and Sublay Mesh to Treat Umbilical Hernia

Phase 4

Terminated

• Conditions: Umbilical Hernia
• Interventions: Procedure: intraperitoneal onlay mesh repair; Procedure: sublay mesh repair

• Registration Number: NCT01201564
• Lead Sponsor: University Hospital, Basel, Switzerland

Brief Summary

This study is designed to compare two techniques for operative care of umbilical hernia in adults regarding wound complications, wound side fluid collections, recurrence rate, postoperative pain, duration of hospitalization and quality of life. The IPOM technique provides mesh positioning directly into the abdominal cavity onto the defect under laparoscopic control while in sublay position the mesh is placed directly behind the rectus muscle after small incision close to the belly button.

Primary Outcome Measures

Name	Time	Method
late wound complications	1 year after operation	* wound infection (with or without removal of the mesh); * wound necrosis; * wound hematoma
early wound complications	30 days after operation	* wound infection (with or without removal of the mesh); * wound necrosis; * wound hematoma

Secondary Outcome Measures

Name	Time	Method
hospital stay	will be measured after discharge of the patient	measured in days
complication rate postoperative	5 years	* trocar site hernia; * enteral fistula; * persistent pain; * re-operation
navel site seroma	after 1 year	the diagnosis of seroma will be given by the surgeon clinically or by ultrasound scan and measured in ccm (height(cm) x width(cm)x length(cm))
pain score (Visual Analog Scale - VAS)	immediately before discharge	will be measured by the nurse according to Visual Analog Scale
complication rate perioperative	intraoperative complications will be recorded immediately after finishing the operation	* major bleeding; * bowel injury
duration of operation	the duration will be recorded immediately after finishing the operation	measured in minutes according to operations protocol (duration cut - suture)
umbilical hernia recurrence rate	5 years	the diagnosis of recurrence will be given by the surgeon clinically or due to ultrasound scan
Quality of life (SF-36)	1 year postoperatively	patients will be asked to fulfill validated SF-36 questionnaire
