Disturbance of sexual function after an operation for rectal cancer and a fundamental study of the relationship between autonomic nerves and arteries in the pelvis.

Akiyo Matsumoto, MD, Kaida Arita, MD. Tsuchiura Kyodo General Hospital

Background: Disturbance of sexual function after an operation for rectal cancer has often occurred. The relationship between autonomic nerves and arteries in pelvis was examined.

Methods: Clinical studies of 15 male patients with resected rectal cancer were performed using Snap Gauge method, Penile-Brachial Index and evoked Bulvo-Cavernous Reflex. In 30 canine experiments, pelvic splanchnic nerve (PSN) electric stimulation, arterial flow measurement, corpus cavernosum pressure measurement and muscle strip study using drugs were evaluated.

Results: In clinical studies of 15 male patients, transection of the hypogastric nerve (HGN) and the sympathetic trunk did not affect the erectile function in the postoperative course. In animal experiments transection of these nerves did not affect the increase in inner pressure of the penis cavernosum. In postoperative cases in which only one side of the lower grade branches of the PSN (S4) were preserved, the erectile function was preserved. In animal experiments in which the PSN of one side was disturbed, the IPA flow of the same side decreased, while the flow of the other side increased. We have evaluated the role of adrenergic components in the PSN on the erectile function in the dog. The effect of norepinephrine hydrochloride on canine vascular smooth muscle was examined in vitro. Vascular smooth muscle strips from the IPA relaxed longitudinally. Electrical stimulation of the PSN increased blood flow in the IPA and also elevated the cavernous pressure. These increases were blocked in part by phentolamine, but not by propranolol or atropine. The effects of cholinergic and adrenergic agonists and antagonists on mechanical responses were also examined in muscle strips obtained from various arteries in the intra-pelvic region including the IPA. Norepinephrine induced contraction in the iliac artery and relaxation in the IPA, and both the contraction and relaxation responses were blocked by phentolamine but not by propranolol. These findings suggest that in the dog, α-adrenergic components projected through the PSN may contribute to penile erection.

Conclusion: Blood flow in the IPA was controlled significantly by the same side PSN, but compensatory by the other side PSN. It is also conceivable that the erectile function through the PSN is controlled by the sympathetic nerve, not by the parasympathetic nerve. In postoperative cases in which only one side of the lower grade branches of the PSN (S4) were preserved, the erectile function was preserved.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
