Incidence, Diagnosis, and Management of Proctological Conditions during Pregnancy

Proctological diseases are highly prevalent during pregnancy, with reported incidence rates ranging from 45% to 68%. The true prevalence is likely higher due to underreporting. These conditions frequently persist into the postpartum period, causing significant discomfort and emotional distress. Physiological changes in the maternal body - including hormonal, metabolic, immunological, and cardiovascular alterations - play a central role in the development of these disorders. The enlargement of the uterus, increased blood volume, and elevated pressure in the pelvic veins contribute to venous stasis in the hemorrhoidal plexus, thereby predisposing pregnant individuals to symptomatic hemorrhoids and perianal thromboses.

The most frequently reported symptoms are anal pain and constipation. Anal pain, which is often intense, is commonly associated with constipation and is due to the high density of sensory nerve endings in the anal canal. Constipation affects more than 60% of pregnant women, primarily as a result of hormonal changes, decreased physical activity, and iron supplementation. Straining during defecation further aggravates proctological conditions, facilitating the development of hemorrhoids, anal fissures, and perianal thrombosis. Diagnosis should include a thorough medical history, physical examination, and proctoscopy. In selected cases, additional imaging may be warranted. Conservative treatment is the mainstay of management, with a focus on symptom control and regulation of bowel habits. Hemorrhoidal disease is particularly common during pregnancy. Conservative treatment includes increased fluid intake, the use of stool softeners, and local cooling measures. Surgical interventions should be reserved for refractory cases and only considered when absolutely necessary. Anal fissures, the second most prevalent condition after hemorrhoids, are primarily caused by constipation. First-line treatment involves stool regulation, analgesic therapy, and the application of topical ointments. While chronic fissures may occasionally require surgical intervention, noninvasive approaches are strongly preferred to minimize risks. Perianal thrombosis, often misdiagnosed as thrombosed external hemorrhoids, typically occurs in the third trimester or shortly after delivery. Conservative therapy is generally effective, focusing on pain control. In selected cases, surgical excision of thrombosed nodules may be indicated.

In summary, proctological conditions during pregnancy are common but usually manageable through accurate diagnosis, conservative treatment, and empathetic patient support. Prioritizing symptom relief and avoiding unnecessary surgical interventions are essential to achieving favorable outcomes.
