Cough and Hemorrhoids

Hemorrhoids are a collection of vascular tissue, smooth muscle, and connective tissue arranged in an inner column along the anal canal. Although they are normal structures, the term "hemorrhoids" refers to a pathological or symptomatic process. Internal hemorrhoids are located above the dentate line and are lined by columnar epithelium, which is innervated by visceral nerve fibers and not associated with pain, depending on the degree of prolapse, according to the Goligher classification. External hemorrhoids lie below the dentate line, are innervated by somatic nerves, and are usually asymptomatic.

Although the most common pathophysiologic cause of hemorrhoids is increased anal pressure at rest, the exact etiologic cause remains unclear. Factors that increase intra-abdominal pressure (IAP), such as straining during a bowel movement, prolonged sitting on the toilet, constipation/diarrhea, obesity, pregnancy, and age-related tissue weakening, can contribute to hemorrhoid development. However, the risk factors for hemorrhoids have not been sufficiently investigated.

The co-contraction of the thoracic, abdominal, and pelvic muscles results in a voluntary or reflex movement. This movement increases intrathoracic and intra-abdominal pressure (IAP), with IAP averaging 81.4-107.6 mmHg during coughing, compared to an average of 16.7 mmHg in the sitting position . The effect of coughing on IAP and its possible complications have been reported in case studies (e.g., urinary incontinence, pelvic organ prolapse) and electromyography studies.

A. Sadiqa et al. reported that hemorrhoids may develop as a gastrointestinal complication of coughing, but the relationship between cough and hemorrhoids has never been prospectively investigated.

Although there are no studies on the prevalence of hemorrhoids in our country, it is the third most common gastrointestinal diagnosis in the USA, with approximately 4 million outpatient and emergency department visits per year. The epidemiology of hemorrhoids has been theorized but remains largely unsupported by reliable research. Simply put, the commonly believed risk factors for hemorrhoids have not been adequately investigated. From an epidemiologic standpoint, whether coughing is a predisposing factor for hemorrhoids will be investigated for the first time in our study. We believe that this study may provide valuable insights for determining goals and strategies for the treatment and management of hemorrhoids, optimizing resource utilization, and offering evidence-based recommendations to patients. The study will be conducted using a prospective observational data collection method. The sample size was calculated using G*Power 3 software (Institute of Experimental Psychology, Heinrich Heine University, Germany). Power analysis showed a medium effect size (Cohen's d: 0.5), and the minimum number of samples required to detect a statistical difference at 95% power and a significance level of α = 0.05 was 134.

Patients diagnosed with hemorrhoidal disease in the general surgery outpatient clinic of our hospital will be included in the study. Demographic information, such as age, gender, educational status, and occupational status, will be recorded for patients who sign the voluntary informed consent form. Additionally, data on the duration of hemorrhoidal disease based on symptomatology, the stage of the disease according to the Goligher classification, the presence of additional proctologic diseases, the presence or absence of constipation symptoms, the severity of bleeding, nutrition and toilet habits, and previous medical or surgical treatments for hemorrhoidal disease will be collected.

Information regarding the presence of cough, additional obstructive pulmonary diseases, medications, smoking or alcohol use, the Leicester Cough Questionnaire, and the Cough Visual Analog Scale (Cough VAS) will also be recorded. Patients with cough will be referred to the Department of Chest Diseases for diagnostic and therapeutic evaluation to investigate the etiology of cough.

If sufficient information is collected from a sufficient number of patients who meet the study criteria, the data will be analyzed.
