Wang: Partial stapled hemorrhoidopexy versus circular stapled hemorrhoidopexy for grade III-IV prolapsing hemorrhoids: a two-year prospective controlled study.

摘要

Dr. Lin and his associates have described a novel modifi cation-partial stapled hemorrhoidectomy (PSH), sug gesting its superiority over the conventional circula stapled hemorrhoidectomy (CSH) [1].The thesis justifying the technique is stated to be tha partial resection with sparing of the mucosal bridges form an elastic ring to enable a better rectal compliance wit resultant improvement in postoperative symptoms. How ever, the mucosal bridges were dissected using electrc cautery and the "dog ears" ligated. I wonder why th authors felt that to be necessary.
