RESUMO
BACKGROUND: Recently, it has been demonstrated that surgical treatment of hemorrhoids in a day-care basis is possible and safe. The aim of this study was to compare the Longo stapled hemorrhoidopexy (SH) and the Milligan-Morgan hemorrhoidectomy (MMH). METHODS: One hundred seventy one patients (95 cases in SH group and 76 cases in MMH group) entered the study: 83 cases were III degree hemorrhoids, 88 IV degree. A priori and a post hoc power analysis were performed. Results, prospectively collected, were compared using chi squared test and student t test. Visual analog scale was used for pain evaluation. Postoperative pain, duration of pain, wound secretion, bleeding, resumption of a normal lifestyle, and postoperative complication were evaluated. RESULTS: Surgical time was 28.41+/-10.78 for MMH and 28.30+/-13.28 min in SH (P=0.94). Postoperative pain was not different between MMH and SH during the first two postoperative days (4.73+/-2.91 vs 5.1+/-3.048; P=0.4), during the following 6 days, patients treated with SH had less pain (4.63+/-2.04 in MMH vs 3.60+/-2.35 in SH; P=0.006). In the SH group, seven patients needed further hospital stay for complicated course. SH showed higher incidence of anal fissure compared with MMH (6.3% vs 0%; P=0.025) but no differences in urinary retention, anal stricture, urgency, or anal hemorrhage. CONCLUSIONS: This study confirms that SH is associated with less postoperative pain and shorter postoperative symptoms, compared with MMH. SH may be a viable addition to the therapy for hemorrhoids with some advantages in early postoperative pain and some disadvantages in postoperative complications and costs.
