Oral sodium phosphate solution is a superior colonoscopy preparation to polyethylene glycol with bisacodyl.

PURPOSE: The aim of this study was to compare the efficacy and patient tolerance of two bowel preparations for colonoscopy. METHODS: Three hundred twenty-three consecutive patients undergoing colonoscopy were randomly assigned to receive either oral sodium phosphate, or 2 liters of polyethylene glycol solution preceded by the stimulant laxative bisacodyl. Patients were asked to record the effects of the preparation, noting any vomiting, nausea, or abdominal pain, and to determine a discomfort rating on a scale of 1 to 5. One hundred sixty-nine patients were assigned to the oral sodium phosphate solution, and 154 to polyethylene glycol with bisacodyl. Surgeons were blinded to the preparation used and rated the quality of the bowel preparation on a scale of 1 to 5. RESULTS: Ninety-nine percent of patients in the sodium phosphate group drank all of the solution as opposed to 91 percent of patients in the polyethylene glycol with bisacodyl group. Patients in the sodium phosphate group reported significantly less discomfort (P = 0.002). No significant difference was reported for vomiting, nausea, or abdominal pain associated with the preparations. The quality of bowel cleansing was considered by the colonoscopists significantly better for the sodium phosphate group than the polyethylene glycol with bisacodyl group (P < 0.000001). CONCLUSIONS: Colonoscopy preparation with sodium phosphate solution is better tolerated and more effective than polyethylene glycol with bisacodyl.

Micronized purified flavonidic fraction compared favorably with rubber band ligation and fiber alone in the management of bleeding hemorrhoids: randomized controlled trial.

PURPOSE: The aim of this study was to assess the role of micronized purified flavonidic fraction in the management of bleeding nonprolapsed hemorrhoids. METHODS: Patients were randomly assigned to receive ispaghula husk alone, rubber band ligation plus ispaghula husk, or micronized purified flavonidic fraction plus ispaghula husk. Other colorectal diseases were excluded by colonoscopy. Blinded observers noted the time for bleeding to stop completely, recurrences, and treatment complications. RESULTS: A total of 162 patients were randomly assigned with no significant differences in the age and gender distributions among the groups. Hemorrhoidal bleeding was relieved most expediently in the micronized purified flavonidic fraction plus ispaghula husk group (ispaghula husk alone n = 66, mean (standard error of the mean) 10.6 (2.3) days; rubber band ligation plus ispaghula husk n = 57, 5.6 (1.1) days; micronized purified flavonidic fraction plus ispaghula husk n = 39, 3.9 (1.2) days; P = 0.03). However, there were no significant differences in the recurrences at six months of follow-up (ispaghula husk alone n = 8 (12 percent); rubber band ligation plus ispaghula husk n = 12 (21 percent); micronized purified flavonidic fraction plus ispaghula husk n = 2 (5.1 percent); P = 0.075). No complications or side-effects were noted. CONCLUSIONS: micronized purified flavonidic fraction used with fiber supplements rapidly and safely relieved bleeding from nonprolapsed hemorrhoids.

Clinical trial of oral diosmin (Daflon) in the treatment of hemorrhoids.

A double-blind, comparative, controlled study on the effectiveness of the addition of oral diosmin (Daflon; Lab. Servier, Orléans, France) and placebo to a conservative regimen of bulk laxative in the treatment of acute symptoms of first-degree and second-degree internal hemorrhoids was undertaken in 100 patients. The diosmin and placebo groups, with 50 patients each, were comparable in age, sex, symptoms, and the severity of the underlying hemorrhoids. During the first four days, the patients received 12 tablets in three divided doses, and then they received two tablets twice daily for another 10 days. Subjective and objective changes were assessed at the 4th and 14th days of treatment. The diosmin group showed statistically significant objective improvement (P < 0.01) without accompanying subjective improvement on the fourth day. However, at day 14, there was no significant difference in either subjective or objective improvement between the two groups. Two cases in the placebo group were taken out of the trial on the fourth day owing to clinical deterioration. No side effect of diosmin was detected in this study.

Oral Fleet Phospho-Soda laxative-induced hyperphosphatemia and hypocalcemic tetany in an adult: report of a case.

PURPOSE: This study was undertaken to report an adverse outcome of the routine use of Fleets Phospho-Soda for bowel cleansing and to review the available literature. METHOD: Report of a case and review of the literature is presented. RESULT: Administration of Fleets Phospho-Soda for bowel preparation in an adult resulted in hyperphosphatemia and hypocalcemic tetany. Review of the literature shows this to be the first such report. Further evaluation suggests a role for partial bowel obstruction and renal failure in this complication. CONCLUSION: Although Fleet Phospho-Soda solution continues to be a safe bowel preparation, caution should be used in adults with bowel obstruction and renal failure.

The role of chronic constipation, diarrhea, and laxative use in the etiology of large-bowel cancer. Data from the Melbourne Colorectal Cancer Study.

Life-long bowel habits of 685 colorectal cancer cases and 723 age/sex frequency matched community controls were investigated as one part of a large, comprehensive, population-based study of colorectal cancer incidence, etiology, and survival, The Melbourne Colorectal Cancer Study. Self-reported chronic constipation was statistically significantly more common in cases than in controls (P = .05). Three or more bowel actions per day were reported by more cases than controls but the total number of respondents in this subset consisted of only ten cases and two controls. Otherwise, the frequency and consistency of bowel motions was similarly distributed among cases and controls. Constipation disappeared as a significant risk when simultaneously adjusted for previously determined dietary risk factors, indicating that it is the diet and not the constipation that is associated with the risk of large-bowel cancer. Additionally, a highly statistically significant association (P = .02) was found with the risk of colorectal cancer in those who reported constipation and also had a high fat intake, a finding consistent with current hypotheses of colorectal carcinogenesis. It is concluded that chronic constipation, diarrhea, and the frequency and consistency of bowel motions, as well as laxative use, are unlikely to be etiologic factors in the development of colorectal cancer. Self-reported chronic constipation is a marginally significant indicator of excess risk of large-bowel cancer and may be used as one of the indices in the screening of individuals for this cancer.

Laxatives after hemorrhoidectomy.

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.

Melanosis coli. Ultrastructural study of 45 patients.

Melanosis coli was diagnosed histologically in colon biopsies of 45 patients with prolonged administration of anthraquinone laxatives. Colonoscopies performed for increased constipation, abdominal pains, or distention disclosed discoloration of the mucosa in only 14 patients. Radiographic studies revealed motility disorders of the colon. In several cases, a circular stenosis occurred at the junction of the colon and the sigmoid, simulating a tumor. Electron microscopy showed abnormalities of the absorptive epithelial cells. The lamina propria contained pigment-laden macrophages, plasma cells, and several nerve fibers in different stages of degeneration. The most striking changes of autonomic nerve elements occurred in patients with the most serious motility disorders.

Bowel function in an urban black African population.

Despite a low daily dietary fiber intake, an urbanized black African population in southern Africa has a low incidence of those diseases associated with fiber deficiency. Stool weights, defecation frequencies, and transit times in this group are much closer to those of westernized whites than to rural blacks.

Management of postoperative constipation in anorectal surgery.

Fifty patients who had undergone proctologic operations were given a combination of standardized senna concentrate and dioctyl sodium sulfosuccinate for prevention or treatment of postoperative constipation. Two Senokot S tablets were given on the evening of the first postoperative day. Patients who had bowel movements after receiving this dose and remained in the hospital received two tablets on each of the following two days. Otherwise, dosage was increased gradually to a maximum of four tablets twice daily until defecation occurred or until the four-day treatment period was over. All patients achieved bowel movements, and in no case was it necessary to administer an enema. No hard stools were passed on the day patients were discharged from the hospital. Overall results were excellent or good in 94 per cent of cases; these results were not affected by age. Ninety-two per cent had bowel movements after the first or second dose was administered. On the day of discharge from the hospital, fecal consistency was satisfactory in 88 per cent of cases and loose in 12 per cent. Except for a single instance of diarrhea after administration of one dose, which involved a patient with a history of loose stools, no side effect occurred during the trial. In view of these responses and the virtual absence of side effects in this study group, Senokot S tablets are judged to be of demonstrated value in the postoperative management of patients undergoing proctologic operations.
