  • Title: A systematic stapling defect - a potential cause of 'anastomotic' leak after restorative proctocolectomy.
    Author: Byrne CM, Uraiqat AA, Phillips RK.
    Journal: Colorectal Dis; 2008 Mar; 10(3):286-8. PubMed ID: 17949446.
    Abstract:
    OBJECTIVE: When constructing ileal-anal pouches with staples, a novel potential cause of anastomotic leak was recently identified at the apex of the pouch. This study was performed to assess this stapling defect. METHOD: Careful inspection of the ileal pouch staple lines was made in eight consecutive pouch constructions. Pouch construction was further evaluated using pig small bowel. RESULTS: When constructing ileal-anal pouches with staples, a novel potential cause of anastomotic leak was recently identified at the apex of the pouch. This defect was present in seven of eight consecutive ileo-anal J-pouches. It was repaired by direct suturing and no clinical or radiological leaks were identified in these patients. In the pig model, the same defect was found in five of five stapled constructions. It was avoiding in five of five cases by limiting the amount of bowel placed into the stapler on the initial firing. CONCLUSION: This defect may be related to stapler design. It can be avoided by using less than the full staple line on the initial firing of the stapler or by using an alternative device. Surgeons creating ileal pouches using staplers, or indeed any use of this particular stapler, need to be aware of this potential for a defect in the staple line and should take steps to avoid the defect or repair it depending on the circumstances.
