Background: The frequencies and types of anal symptoms were compared with the frequencies and types of benign anal diseases (BAD). Methods: Patients transferred from GPs, physicians or gynaecologists for anal and/or abdominal complaints/signs were enrolled and asked to complete a questionnaire about their symptoms. Proctologic assessment was performed in the knee-chest position. Definitions of BAD were tested in a two year pilot study. Findings were entered into a PC immediately after the assessment of each individual. Results: Eight hundred seven individuals, 539 (66.8%) with and 268 without BAD were analysed. Almost one third (31.2%) of patients with BAD had more than one BAD. Concomitant anal findings such as skin tags were more frequently seen in patients with than without BAD (<0.01). After haemorrhoids (401 patients), pruritus ani (317 patients) was the second most frequently found BAD. The distribution of stages in 317 pruritus ani patients was: mild (91), moderate (178), severe (29), and chronic (19). Anal symptoms in patients with BAD included: bleeding (58.6%), itch (53.7%), pain (33.7%), burning (32.9%), and soreness (26.6%). Anal lesions could be predicted according to patients' answers in the questionnaire: haemorrhoids by anal bleeding (p=0.032), weeping (p=0.017), and non-existence of anal pain (p=0.005); anal fissures by anal pain (p=0.001) and anal bleeding (p=0.006); pruritus ani by anal pain (p=0.001), itching (p=0.001), and soreness (p=0.006). Conclusions:The knee-chest position may allow for the accumulation of more detailed information about BAD than the left lateral Sims' position, thus enabling physicians to make more reliable anal diagnoses and provide better differentiated therapies.

BackgroundIt is important to better understand the aetiology of thrombosed external haemorrhoids (TEH) because recurrence rates are high, prophylaxis is unknown, and optimal therapy is highly debated.FindingsWe conducted a questionnaire study of individuals with and without TEH. Aetiology was studied by comparison of answers to a questionnaire given to individuals with and without TEH concerning demography, history, and published aetiologic hypotheses. Participants were evaluated consecutively at our institution from March 2004 through August 2005.One hundred forty-eight individuals were enrolled, including 72 patients with TEH and 76 individuals without TEH but with alternative diagnoses, such as a screening colonoscopy or colonic polyps. Out of 38 possible aetiologic factors evaluated, 20 showed no significant bivariate correlation to TEH and were no longer traced, and 16 factors showed a significant bivariate relationship to TEH. By multivariate analysis, six independent variables were found to predict TEH correctly in 79.1% of cases: age of 46 years or younger, use of excessive physical effort, and use of dry toilet paper combined with wet cleaning methods after defaecation were associated with a significantly higher risk of developing TEH; use of bathtub, use of the shower, and genital cleaning before sleep at least once a week were associated with a significantly lower risk of developing TEH.ConclusionSix hypotheses on the causes of TEH have a high probability of being correct and should be considered in future studies on aetiology, prophylaxis, and therapy of TEH.

Background: It is unknown whether surgery is the gold standard for therapy of thrombosed external hemorrhoids (TEH). Methods: A prospective cohort study of 72 adults with TEH was conducted: no surgery, no sitz baths but gentle dry cleaning with smooth toilet paper after defecation. Follow-up information was collected six months after admission by questionnaire. Results: Despite our strict conservative management policy 62.5% (45/72) of patients (95% confidence interval [CI]: 51.0-74.0) described themselves as "healed" or "ameliorated", and 61.1% (44/72, 95% CI: 49.6-72.6) found our management policy as "valuable to test" or "impracticable". 13.9% (10/72, 95% CI: 5.7-22.1) of patients suspected to have recurrences. 4.2% did not know. Twenty-two of the 48 responding patients reported symptoms such as itching (18.8%), soiling (12.5%), pricking (10.4%), or a sore bottom (8.3%) once a month (59.1%, 13/22), once a week (27.3%, 6/22), or every day (13.6%, 3/22). Conclusions:The dictum that surgery is the gold standard for therapy for TEH should be checked by randomized controlled trials.

Background:It is unknown which proctological position is most embarrassing to patients. Methods: Individuals consecutively referred to our outpatient clinic in order to determine the causes of anal and/or abdominal complaints were randomized to complete an unvalidated six-item questionnaire which asked for their preferred proctologic positioning either before or after a proctological examination in knee-chest position followed by inspection of the anal verge, digital examination of the anal canal, and anoscopy. A third group of patients referred for gastroscopy was asked to complete the questionnaire before being gastroscoped. Results: One hundred seventy-eight individuals of both genders aged 16-80 years who consecutively entered our outpatient clinic were enrolled. One third in each group had never experienced any of the offered medical positionings. Most patients favored the Sims' position if they had the choice. Randomized patients favored the knee-chest position more after experiencing it compared to those without experience (P  0.03). Patients favored the positions they had recently experienced irrespective of the other positions offered in the questionnaire (P  0.05). Individual answers to the question 'which position do you find most embarrassing?' did not depend on sex or age at first examination or when their last examination was performed. The majority of patients (55.2%-71.4%) held that no type of proctological positioning was most embarrassing to them. Conclusions: The medical profession is authorized to use the proctological positioning that allows the most reliable anal diagnoses.
