Internal sphincter and haemorrhoids: a pathological study.
نویسندگان
چکیده
Histological examination of the lower margin of the internal sphincter has demonstrated an increased amount of fibrous tissue in patients with haemorrhoids compared with controls. This finding may be of relevance to the treatment of haemorrhoids by maximal anal dilatation.

Internal sphincter and the nature of haemorrhoids.
Internal anal sphincter activity has been studied in 84 patients with haemorrhoids and 40 asymptomatic subjects. Activity was estimated by measuring maximum resting anal pressure with a water filled anal balloon probe 7 mm in diameter connected to a strain gauge pressure transducer. There was greater activity of the internal sphincter in patients with haemorrhoids than in controls, but there wa...
متن کاملTreatment of Piles by Pilex Tablets and Ointment
PATHOLOGICAL ANATOMY Internal piles are essentially varicosities of the venous plexuses in the wall of the anal canal and lower most half inch or so of the rectum. These form a swelling covered with mucosa and bulge into the lumen of the anal canal; this is specially so when portal venous pressure is raised and the sphincter is relaxed during defaecation. Internal haemorrhoids in association wi...
متن کاملProspective trials of minor surgical procedures and high-fibre diet for haemorrhoids.
Two hundred and sixteen consecutive patients seen for the first time with symptomatic haemorrhoids entered trials of conservative and minor surgical treatment. They were divided into two groups according to their pretreatment maximal anal pressure. Patients with pressures of 100 cm H2O (73.7 mm Hg) or more (108 patients) were treated by anal dilatation (37), sphincterotomy (34), or high-fibre d...
متن کاملMeasurement of anal pressure and motility.
A fine open perfused system and a closed balloon system for the measurement of anal pressure and motility have been compared. Measurements were made in 40 normal subjects and 84 patients with haemorrhoids. The rate of perfusion had a marked effect on the recorded pressure and motility details. The motility pattern was seen most clearly with the balloon probe and the pressure recorded was reprod...
متن کاملHypertrophy of the external and sphincter in haemorrhoids: a histometric study.
Biopsies of the external and sphincter taken from 24 male patients with haemorrhoids were subjected to examination using histochemical techniques. Fibre size (type 1 mean: 33 micrometers +/- 11.0 SD and type 2 mean: 47.9 micrometers +/- 15.0 SD) was increased when compared with control subjects. The distribution of muscle fibre types in these patients showed markedly greater type 1 fibre predom...
