Effects of two suture methods on the width of resected rectal mucosa in procedure for prolapse and hemorrhoids / 国际外科学杂志

ABSTRACT

Objective Extrapolate the relationships between the width of circumferential rectal mucosa re-sected and the method of either performing single purse-string or performing double purse-string during per-forming the procedure for prolapse and hemorrhoids (PPH), and to assess the impact of both the level of sta-ple line and the width of rectal mucosa resected on clinical outcomes after stapled hemorrhoidpexy. Meth-ods Twenty-eight adult patients with Ⅲ-Ⅳ hemorrhoids were assigned to two groups 15 patients using sin-gle pursestring and the remaining 13 patients using double purse-string. The mucosal width of doughtnuts of both groups were measured and the data recorded. The doughtnuts resected were sent to pathology examina-tion after stapled hemorrhoids pexy to identify whether or not the specimens involved the smoth muscles. The demographic complications (bleeding, postoperative pain, urinary retention, fecal urgency) were compared and statistically analysed between the two groups, respectively. Results There were no statistical differ-ences between the two groups in terms of postoperative short-term results and complication rates, as well as the proportion of involving smooth muscle in specimens(P >0.05). However, when compared the width of doughtnuts resected in single-pursestring group was smaller than that in double-parse-string group (P < 0. 01). Conclusion The single or double-purse-string suture in PPH can control the width of resected rectal mucosa.
