Objective
The surgical treatment of a parastomal hernia is always challenging due to the high incidence of recurrence following primary repair, or stoma relocation and severe morbidities in prosthetic repair with polypropylene materials. We therefore developed a modified sublay–keyhole technique employing a polypropylene material to minimize the associated high risk of the procedure. We herein describe our initial clinical experience with this modified procedure.
Methods
A retrospective review was performed to obtain the clinical data for 11 patients with parastomal hernias who underwent the modified in situ Sublay–keyhole repair from November 2008 to August 2010.
Results
The mean hernia size was 58.7 cm2 (range 30–96 cm2), with an average polypropylene mesh size of 376.3 cm2 (range 270–464 cm2). The mean length of the operation was 147.9 min (range 120–195.0 min), and the mean postoperative hospital stay was 11 days (range 9–14 days). All patients had an uneventful incisional recovery, with no infections. Two seromas and one hematoma were found and treated with conservative management, such as with aspiration, physical therapy and compression. All patients had been followed up, with a mean length of follow-up of 23.5 months (range 11–39 months). One parastomal hernia recurrence was seen 11 months postoperatively. Breakdown of the sutures and an over-sized aperture cut in the mesh were detected as the causes of the recurrence during the secondary repair procedure. Only re-sutures in both the mesh aperture and myofascial dehiscence were executed for this patient, and no re-recurrence was observed during an additional follow-up of 15 months. No recurrence of the parastomal hernia or presentation of an incisional hernia was detected during the follow-up.
Conclusions
The modified Sublay–keyhole repair appears to be an effective procedure for parastomal hernias, with a low incidence of recurrence and risk of morbidities. Collection of more cases and further follow-up examinations will be needed to confirm our findings.
