Anal manometric findings in symptomatic hemorrhoids

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Physiology

Background:

• Symptomatic hemorrhoids affect a significant portion of the population.
• Understanding the underlying physiological mechanisms of hemorrhoids is crucial for effective management.
• Anal manometry is a key diagnostic tool for assessing anorectal function.

Purpose of the Study:

• To investigate anal manometric findings in patients with symptomatic hemorrhoids.
• To compare anorectal pressures between hemorrhoid patients and healthy controls.
• To explore correlations between manometric parameters and hemorrhoid symptoms.

Main Methods:

• Anal manometry was performed using a continuously perfused catheter and pull-through technique.
• Fifty patients with symptomatic hemorrhoids were compared to 50 age- and sex-matched controls.
• Data analysis focused on basal pressure and maximal voluntary contraction pressure.

Main Results:

• Patients with symptomatic hemorrhoids demonstrated significantly higher maximal basal pressure (P<0.02) and maximal voluntary contraction pressure (P<0.05) than controls.
• A negative correlation was observed between age and basal pressure in both groups.
• Patients with bleeding hemorrhoids showed higher basal pressures (P<0.05) than those with prolapsing hemorrhoids.

Conclusions:

• Symptomatic hemorrhoids are associated with altered anal sphincter pressures.
• Higher anal pressures may be a contributing factor or consequence of hemorrhoidal disease.
• Further research is needed to elucidate the precise role of anal pressures in hemorrhoid pathophysiology.
