Anal manometric studies in hemorrhoids and anal fissures

Diseases of the Colon and Rectum
J K Lin


Manometric study with the use of continuous water perfusion system was performed on 50 patients with Grade III or IV hemorrhoids and for 29 patients with chronic anal fissure. Another 36 patients who had no anorectal symptoms or pathology were chosen as the control group. The maximal basal pressures for the controls, hemorrhoids, and chronic anal fissures were 71.2 +/- 24.9, 85.3 +/- 27.7, and 87.4 +/- 38.8 mmHg, respectively; the maximal contraction pressures for the controls, hemorrhoids, and fissures were 132.9 +/- 44.9, 158.8 +/- 58.0, and 162.1 +/- 64.5 mmHg, respectively; the lengths of the functional sphincter of the three groups were 3.7 +/- 0.5, 3.8 +/- 0.8, and 3.9 +/- 0.6 cm, respectively. The maximal basal pressures and maximal contraction pressures of the hemorrhoid and fissure patients were significantly greater than those of the control group (t test, P value less than 0.05); whereas the functional sphincter lengths of the three groups showed no significant difference.

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, as well as fevers and skin rashes. Here is the latest research on this disease.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.


Trichotillomania is an impulse control disorder characterized by the recurrent pulling of one's hair resulting in noticeable hair loss. Here are the latest discoveries in this field.

DDX3X Syndrome

DDX3X syndrome is caused by a spontaneous mutation at conception that primarily affects females due to its location on the X-chromosome.
