ABSTRACT
Objective To investigate the operative technique and efficacy of PPH for severe hemorrhoids. Methods The clinical data of 153 cases of severe hemorrhoids treated by PPH, individualized according to size and nature of the piles, concomitant morbidities and conditions at the dentate line, and analysis of the relevance between operative technique and clinical efficacy as well as postoperative complications, were revieuled retropectively. Results All of the prolapsed tissue retracted immediately. Bleeding at the anastomotic site occurred in 49 cases, pulsatile bleeding in 12 cases, all of which were sutured under direct vision with cessation of bleeding. The width of excised-tissue was 2.1~4.6cm(average 3.5cm). The main symptoms of patients on the 1st post-operation day were abdominal distention caused by dysuria, pain, and tenesmus and burning sensation. At followup of 1-40 months, there was no stenosis of stoma, anal incontinence or recurrence of prolapse. After operation, a very satistactory result was achieved in 87 cases, satisfactory in 63 cases and mostly satisfactory in 3 cases. Conclusions In order to achieve ideal results with good retraction of tissues, avoidance of complications and improve patient satisfactory rate, the use of PPH for severe hemorrhords must be individualized and technical skill during operation are important.
