BACKGROUND: A large proportion of patients with anorectal complaints are referred to colorectal surgeons with the label of hemorrhoids. OBJECTIVE: The purpose of this study was to review presenting symptoms and frequency of accurate diagnosis, as well as to analyze determinants of misdiagnosis to guide educational endeavors. DESIGN: This was a retrospective study. SETTINGS: The study was conducted at a tertiary care academic center. PATIENTS: The charts of patients referred to a colorectal clinic with the diagnosis of hemorrhoids from January 1, 2012, to January 1, 2017, were reviewed. MAIN OUTCOME MEASURES: The accuracy of the referring provider's diagnosis of hemorrhoids was measured. RESULTS: Review of charts identified 476 patients with the referral diagnosis of hemorrhoids. The most common presenting symptoms were bleeding (63%; n = 302), pain (48%; n = 228), and protrusion (39%; n = 185). Anal examination (ie, external inspection and/or digital internal examination) was documented in only 48%. The hemorrhoid diagnostic accuracy was 65% (n = 311). Among patients with incorrect hemorrhoid diagnoses (35%; n = 169), actual diagnosis was anal fissure (34%), skin tag (27%), and hypertrophied papilla (6%). One rectal and 2 anal carcinomas were found (0.63%). Compared with general practitioners, gastroenterologists had 86% higher odds of correct diagnosis (OR = 1.86 (95% CI, 1.10-3.10); p = 0.02), whereas the gynecologists had 68% lower odds of correct diagnosis at the time of referral (OR = 0.32 (95% CI, 0.10-0.80); p = 0.02). On multivariable analysis, referring specialty was not predictive of accurate diagnosis. Patients presenting with protrusion had 73% higher odds of accurate diagnosis (OR = 1.7 (95% CI, 1.1-2.7); p = 0.02), whereas patients presenting with pain (OR = 1.6 (95% CI, 1.1-2.5); p = 0.03) or pruritus (OR = 2.5 (95% CI, 1.2-5.0); p = 0.008) were more likely to be misdiagnosed. LIMITATIONS: This is a retrospective study. Not all of the charts contained all data points. The number of patients may limit the power of the study to detect some differences. CONCLUSIONS: A variety of anorectal complaints are diagnosed as hemorrhoids by providers who have initial contact with the patients. Educational programs directed toward improving physician knowledge can potentially improve diagnostic accuracy and earlier initiation of appropriate care. Presenting symptoms other than protrusion lead to higher rate of misdiagnosis by a referring physician. See Video Abstract at http://links.lww.com/DCR/A847.
