Anorectal Manometry of Patients With Constipation Predominant Irritable Bowel Syndrome

Chronic constipation (CC) is a common medical problem throughout the world [1-3] The global prevalence of CC in the community varies from 11% to 18% [4].

In patients presenting to tertiary care facilities, specific pathophysiological abnormalities like defecatory disorder and slow colonic transit contribute to CC.

CC has a significant burden on the utilization of healthcare resources, including the cost of inpatient and outpatient care, laboratory tests, and diagnostic procedures [5, 6].

CC is characterized by difficulty in passing stools or a low frequency of bowel movements, often accompanied by straining during defecation or a feeling of incomplete evacuation [7, 8].

For western population, CC is defined by Bristol stool form (BSF) I-II, while in Indian patients, addition of type III Bristol stool form increases diagnostic sensitivity [2]. In the ROME IV criteria, it has been suggested that all patients with CC without evidence of structural or metabolic abnormalities to explain symptoms should be considered under the umbrella of functional constipation (FC) [8].
