Thirty patients undergoing a standard Milligan-Morgan hemorrhoidectomy were used for a randomized study of the addition of postoperative laxatives or wheat fiber to the diet. Seventeen patients received wheat fiber; 13 were given a laxative regime of sterculia, magnesium sulfate, and mineral oil. There were no differences between the two groups in preoperative or postoperative bowel habits. Patients receiving wheat fiber had a shorter postoperative hospital stay four days (three to five) vs. five days (three to six), median (range), P less than .01, and suffered less pain after defecation on the day of discharge from the hospital (P less than .05). Fecal leakage or soiling was seen less frequently with wheat fiber than in patients receiving the laxative regime (5/17 vs. 10/13, P less than .05). The authors conclude that wheat fiber added to the diet will produce a satisfactory bowel habit after hemorrhoidectomy, with a lower incidence of fecal leakage and reduced pain after defecation than the usual laxative regime.
30例行标准Milligan-Morgan痔切除术的患者被用于一项随机研究，该研究旨在探讨术后添加泻药或饮食中添加麦麸纤维的效果。17例患者接受麦麸纤维；13例采用包含硬脂酸、硫酸镁和矿物油的泻药疗法。两组患者术前或术后的排便习惯无差异。接受麦麸纤维的患者术后住院时间较短，中位数为4天（3至5天），而接受泻药疗法的患者为5天（3至6天），P<0.01，且出院当天排便后疼痛较轻（P<0.05）。与接受泻药疗法的患者相比，麦麸纤维组患者粪便渗漏或污染的情况较少见（5/17 vs. 10/13，P<0.05）。作者得出结论，饮食中添加麦麸纤维在痔切除术后可产生令人满意的排便习惯，与常规泻药疗法相比，粪便渗漏发生率更低，排便后疼痛减轻。
