Evaluation of effect of Mesh in Umbilical Hernia Repair with Smaller Defect than 1 cm

Background and Despite of many improvements which have been happened in abdominal wall hernia repair but there are differential Ideas about the best method of hernia repair. Umbilicus is the most weaken of abdominal wall and Umbilical hernia is a common complication of adult population. It is multifactorial disease but the most important factors are chronic abdominal pressure and weakness of facia. There are two methods in repair. Mayo and tension free repair with mesh. The latter is associated with less recurrent and more effective and it is choice of abdominal wall hernia repair in large defects (≥3-4 cm) but small defects repair with Mayo technical.after primary repair (Mayo) rate of recurrent is range from %10-%30. because there is high recurrent rate in Mayo repair we did this study about using of mesh in the patients with umbilical hernia and small defect (<=1). Between oct 2006-apr 2008 we performed a randomized clinical trial in 80 patients referred to department of surgery of the Imam Khomeini hospital in Sari-Iran which were candidate for umbilical hernia repair. patients divided to case and control groups randomly and were followed up by physical examination abouth infection and recurrent and other potential risk factors then analized byspss soft ware and kai-squer study. Among 40 patiants with Mayo repair there were infection in 3 patiants and recurrence in 7 patiants but infection and recurrence is not seen in mesh repair group. There were meaningfull statistical difference between the groups in recurrence (% 17.5 in Mayo repair and zero mesh repair). Between 2 groups of patients with umbilical hernia and small defect mesh repair is bether than Mayo repair and recommend to use of mesh in repair of patients with umbilical hernia at any size if there is risk factors obesity, multiparity and other causes of high abdominal pressure.
