Appendicectomy: an assessment of the advisability of stump invagination

Abstract

Seven hundred and thirty-two cases of appendicectomy performed over a period of 5 years are reviewed to compare the incidence of complications and the length of the postoperative stay in hospital, depending on whether the appendix stump was simply ligated or was invaginated by purse string suture following ligation. No detrimental effects are noted following simple ligation, whereas patients who had stump invagination remained in hospital on average more than a day longer, mainly owing to a higher incidence of wound infection (16 per cent as against 6 per cent).
