Does colorectal endometriosis alter intestinal functions? A prospective manometric and questionnaire-based study

Area of Science:

• Gastroenterology
• Gynecology
• Colorectal Surgery

Background:

• Rectosigmoid deep infiltrating endometriosis can impact bowel function.
• Understanding the relationship between endometriosis and intestinal dysfunction is crucial for patient management.

Purpose of the Study:

• To objectively assess intestinal function in patients with rectosigmoid endometriosis using anorectal manometry.
• To identify subjective defecatory dysfunctions experienced by these patients.

Main Methods:

• Prospective study involving 25 patients diagnosed with rectosigmoid endometriosis.
• Anorectal manometry was performed to evaluate rectal and anal function.
• Patients completed questionnaires on defecatory functions and pain, with pain scored using a Visual Analogue Scale.

Main Results:

• No significant alterations in the rectoanal inhibitory reflex were observed.
• Internal anal sphincter hypertone was detected in 20 out of 25 patients.
• Subjective findings included incomplete evacuation as the most common symptom, with some patients reporting increased defecation threshold or reduced squeeze pressure.

Conclusions:

• Anorectal manometry did not reveal marked motility or sensitive dysfunctions in patients with rectosigmoid endometriosis.
• Internal anal sphincter hypertone is a common finding in these patients.
• Subjective reports highlight prevalent defecatory disorders, emphasizing the need for comprehensive patient evaluation.
