Ann Surg. 2010 May;251(5):807-18. www.downstatesurgery.org COMPLICATIONS OF RECTAL SURGERY Wound infection 7% Anastomotic leak 11% Pelvic sepsis 12% Postop death 2% Fecal incontinence Perineal wound infection Perineal wound breakdown Perineal Fistula Paun BC et al.

Colorectal Dis. 2009 Oct;11(8):806-16. www.downstatesurgery.org OPTIONS FOR PERINEAL CLOSURE Open drainage Suture of perineal wound and pelvic peritoneum Suture of perineal wound without suture of pelvic peritoneum Use of mesh sling to close peritoneum Placement of various drains Open drains Closed suction drains Vacuum devices Antibiotic impregnated products Omentoplasty Myocutaneous flap reconstruction www.downstatesurgery.org WHAT SHOULD WE DO? There have been no good, randomized, controlled trials comparing the various methods of perineal closure available today There are many case series that support the effectiveness of various techniques Practice guidelines for any particular closure method cannot be given with the current studies available www.downstatesurgery.org HISTORY In traditional surgery, primary healing was considered impossible In the 1970’s, several studies compared open drainage vs. primary closure of the perineum Incidence of primary wound healing was higher with primary closure (45-49%) Incidence of persistent sinuses and unhealed wounds was lower Wounds that were closed primarily and then reopened secondary to infection had similar results to wounds that were left open primarily Irvin TT, Goligher JC.

Leaving peritoneum open allows small bowel to descend into pelvis Creates difficulty if pt develops SBO or recurrence of tumor Risk of evisceration if perineal wound opens Radiation can affect small bowel Closing the peritoneum creates an empty space in the pelvis May lead to higher rate of infection Robles R et al.

(p=0.124) www.downstatesurgery.org OMENTOPLASTY Greater omentum can be used to fill the dead space in the pelvis after APR Brings well vascularized, non-irradiated tissue No randomized trials are available Recent review of the literature found 4 cohort studies and 6 case series Total 366 patients Only 2 of the cohort studies had adequate controls Cohort studies found statistically significant improvement in healing rates and complication rates No adequate evidence for or against omentoplasty Nilsson PJ.
