title: [Repair in situ of parastomal hernia with modified sublay-keyhole technique].
abstract: OBJECTIVE
  To investigate the procedure and the effectiveness of modified Sublay-Keyhole technique for repair in situ of parastomal hernia.
  
  
  METHODS
  Between October 2007 and March 2010, 11 patients with parastomal hernia underwent modified Sublay-Keyhole technique for repair in situ. There were 5 males and 6 females with an average age of 63 years (range, 55-72 years). The average body mass index was 28.2 (range, 23.5-32.5). All stomas in patients were permanent, including 6 end colostomies caused by abdominal perineal resection for rectal cancer, 2 end ileostomies secondary to total colon resection for ulcerative colitis, and 3 end ileostomies following ileal conduit for bladder resection. One patient underwent previous prothetic repair with polypropylene mesh. The average time from last operation to admission was 2.5 years (range, 1-4.5 years). According to classification criteria of George Eliot hospital, 3 cases were classified as grade 2b, 2 as grade 3a, 5 as grade 3b, and 1 as grade 4. The average longest diameter of hernia ring was 9.5 cm (range, 6-12 cm).
  
  
  RESULTS
  Reconstructions of abdominal wall in all patients were performed successfully through modified Sublay-Keyhole technique. The average size of hernia ring was 75.5 cm2 (range, 30-112 cm2), and the average size of polypropylene mesh was 280.5 cm2 (range, 175-360 cm2). The average operative time was 165 minutes (range, 120-195 minutes) and the average postoperative hospitalization days were 11 days (range, 9-14 days). All patients achieved healing of incision by first intention with no abdominal wall infection. Seroma and hematoma occurred in 2 patients and 1 patient, respectively, and were cured by needle aspiration and pressure bandaging. All patients were followed up 26.3 months on average (range, 10-39 months). One case suffered from parastomal hernia recurrence at 11 months postoperatively because of suture loosening and too wide aperture in mesh; and re-sutures in both mesh aperture and myofascial dehiscence were given and no recurrence was observed during additional follow-up of 15 months. No parastomal hernia recurrence or incisional hernia occurred in the other 10 patients.
  
  
  CONCLUSIONS
  Modified Sublay-Keyhole technique is an effective procedure for reconstruction of abdominal wall in patients with parastomal hernia for low recurrence incidence and less complications. But the long-term effectiveness needs further follow-up.
