“…Numerous modifications of the technique have been described including using a single PPH-01 stapler, two PPH-01 staplers, the semi-circular Contour 30 stapler, a Contour and a linear stapler, a Contour with two linear staplers, and a Contour with a PPH-01. 74 Overall, the early results seem promising, but some serious complications have been reported including rectal obliteration, rectal perforation, pelvic sepsis, staple-line hematoma, chronic proctalgia, and rectovaginal fistula. [75][76][77][78] Furthermore, there is no consensus on which technique should be applied to which patient or what factors are predictive of success.…”
