    Notes: Abstract The effect of abdominal rectopexy on bowel function is difficult to assess in retrospective studies because preoperative bowel habit cannot be determined accurately. This study examined bowel symptoms and physiologic tests of anorectal function prospectively in 23 patients before and at three months after rectopexy. Rectopexy eliminated complete prolapse in all and stopped bleeding in 16 of 18 patients. Incontinence improved significantly. Constipation (〈3 bowel actions per week or straining for more than 25 percent of defecation time) was relieved in 4 of 11 affected patients but developed in 5 of the 12 who were not constipated preoperatively. Since the median bowel frequency was 21 motions per week before surgery and 17 afterward, the main determinant of constipation was straining. Abdominal pain was relieved after rectopexy in 6 of 12 patients but developed in 3 of 13 who were pain-free before surgery. Three patients (13 percent) had a first-degree relative with rectal prolapse. Perineal descent decreased significantly. Maximal anal resting pressure increased significantly, but this did not correlate significantly with improved continence. Twenty-one patients (91 percent) could expel a 50-ml balloon preoperatively; 18 of those 21 could still do so postoperatively. The two patients who could not expel the balloon preoperatively were able to do so postoperatively. This study shows that rectal prolapse is associated with profoundly abnormal defecation and abdominal pain. While abdominal rectopexy improved continence, it may improve or worsen other bowel symptoms, including constipation.

    Description / Table of Contents: Résumé L'hemorroïdectomie au laser CO2 est praticable et sûre à la condition que son emploi doit fait avec prudence. L'emploi du laser entraîne une diminution de la consommation d'analgésiques post-opératoires. Le laser CO2 ne cause pas d'altérations significatives dans la physiologie ano-rectale.
    Notes: Abstract Carbon dioxide (CO2) laser haemorrhoidectomy is feasible and safe provided it is used with care. It is associated with a reduced requirement for post-operative analgesia. The CO2 laser caused no significant alteration in anorectal physiology.

    Description / Table of Contents: Résumé Pour étudier les anomalies de la conduction sensitive dans les maladies ano-rectales nous avons évalué la perception sensitive périphérique et les potentiels évoqués somesthésiques produits par la stimulation rectale chez des contrôles et des patients avec soit une constipation, soit une incontinence fécale idiopathique. Les potentiels évoqués étaient aussi enregistrés après stimulation du nerf tibial postérieur ou du nerf dorsal génital. La sensation rectale était aussi étudié par stimulation électrique. L'enregistrement reproductible des potentiels évoqués après stimulation ano-rectale était possible chez seulement une minorité de sujets et en cas d'enregistrement montrait des variations entre les sujets et chez un même sujet. Dans le groupe des malades constipés il y avait une différence significative de la sensation rectale électrique (P〈0.05) avec les contrôles. Nous concluons que les tests sensitifs périphériques montrent une anomalie chez les malades ayant une constipation sévère. Cependant les potentiels évoqués cérébraux ne peuvent être valablement enregistrés après stimulation rectale et lorsqu'ils sont enregistrés les latences ont un taux de variation trop large pour être discriminatif entre les sujets sains et malades. Ceci est probablement en relation avec la différence entre les voies de conduction somatiques et viscérales.
    Notes: Abstract To assess abnomalities of sensory conduction in anorectal disease we have evaluated peripheral sensory perception and somatosensory evoked potentials produced by rectal stimulation in control subjects and patients with either constipation or idiopathic faecal incontinence. Evoked potentials were also recorded after posterior tibial and dorsal genital nerve stimulation. Rectal sensation was also assessed using electrical stimulation. Reproducible evoked potential recordings after anorectal stimulation were possible in only a minority of subjects and when recorded showed intersubject and intrasubject variation. In the constipated group there was a significant difference in rectal electrical sensation (P〈0.05) from controls. We conclude that peripheral sensory testing demonstrates an abnormality in severe constipation. However, cerebral evoked potentials cannot be reliably recorded after rectal stimulation, and when recorded the latencies are of too broad a range to discriminate between health and disease. This probably relates to the difference between somatic and visceral pathways.

    Description / Table of Contents: Résumé Le sphincter anal interne a une innervation intrinsèque et extrinsèque qui règle son activité. Tandis que la nature de l'innervation extrinséque a été bien caractérisée il n'en est pas de même pour l'innervation intrinséque. Quoiqu'une variété de neurotransmetteurs a été identifiée dans le sphincter anal interne humain, le rôle physiologique chez l'adulte sain et leur possible participation dans les processus pathologiques ont été peu étudiés. Par immunohistochimie, nous avons étudié la distribution et la densité dans les fibres nerveuses d'une série de neuropeptides au niveau du sphincter anal interne de 12 patients atteints de cancer (contrôle) et de 16 patients avec une incontinence fécale neurogénique. Nous avons aussi étudié l'effet in vitro du VIP, neuropeptide tyrosine, et galanine sur des préparations isolées de sphincter anal interne de 11 cancers contrôles et de 5 patients avec incontinence neurogénique. Il n'y avait pas de différence dans la distribution ou la densité des neuropeptides entre les deux groupes de patients et il n'y avait pas de différence qualitative dans les réponses in vitro du sphincter aux neuropeptides. Ces résultats suggèrent que ces neuropeptides composant de l'innervation intrinséque du sphincter anal interne ne sont pas affectés chez les patients avec incontinence neurogénique.
    Notes: Abstract The internal anal sphincter has both an intrinsic and extrinsic innervation which modulates its activity. While the nature of the extrinsic innervation has been well characterised, the same is not true of the intrinsic innervation. Although a variety of neurotransmitters have been identified in the human internal anal sphincter, their physiological role in health, and possible involvement in disease processes, have received little attention. Using immunohistochemistry we have studied the distribution and nerve fibre densities of a range of neuropeptides in the internal anal sphincter from 12 cancer patients (controls) and from 16 patients with neurogenic faecal incontinence. We have also studied the in vitro effect of vasoactive intestinal peptide, neuropeptide tyrosine, and galanin on isolated preparations of the internal anal sphincter from 11 cancer controls and 5 patients with neurogenic faecal incontinence. There was no difference in either the distribution or density of the neuropeptides between the 2 groups of patients, and there was no qualitative difference in the in vitro responses of the sphincter to the neuropeptides. These findings suggest that these neuropeptide components of the intrinsic innervation of the internal anal sphincter are unaffected in patients with neurogenic faecal incontinence.
