One discussion this week involved the Sugarbaker repair vs Keyhole repair.

Summary:  The primary differences between keyhole repair and Sugarbaker repair are the orientation of the bowel and the presence of a slit in the mesh. In the modified Sugarbaker approach, the bowel is exteriorized through the side of the mesh, whereas in the Keyhole approach the bowel is inserted through a 2 to 3 cm slit in the center of mesh. Both methods apply the mesh intraperitoneally (DeAsis et al, 2015, p.8673).

DeAsis et al (2015) performed a systematic review of PubMed and Medline. The primary outcome analyzed was recurrence of parastomal hernia. Secondary outcomes were mesh infection, surgical site infection, obstruction requiring reoperation, death, and other complications.

In an analysis of 15 articles involving 469 patients, the recurrence rate was 10.2% (95%CI: 3.9-19.0) for the modified laparoscopic Sugarbaker approach, and 27.9% (95%CI: 12.3-46.9) for the keyhole approach. There were no intraoperative mortalities reported and six mortalities during the postoperative course.

The review concluded that the non-slit mesh modified Sugarbaker approach and the slit mesh Keyhole approach are currently the most reported options for laparoscopic repair. When choosing between the two, a modified Sugarbaker technique appears to be a superior method given the low recurrence rates compared to the keyhole technique if an ePTFE mesh is used (p.8676).
