Haemorrhoidal artery distribution in patients with grade III and IV haemorrhoids treated with artery ligation and rectoanal repair. Assessment of Doppler guidance / Distribución de las arterias hemorroidales en pacientes con hemorroides de grado III y IV tratados mediante ligadura arterial y reparación rectoanal. Evaluación del guiado Doppler

Introduction: While haemorrhoidal dearterialization and mucopexy are accepted as a valid alternative to haemorrhoidectomy, differences exist regarding the fixed or variable location of the arteries to be ligated. Our aim was to shed light on this issue of arterial distribution in candidates for surgery. Methods: The study included consecutive patients diagnosed with Goligher grade III and IV haemorrhoids, who had undergone Doppler-guided haemorrhoidal artery ligation (DG-HAL) and rectoanal repair (RAR) at 2 medical centres in Spain. The main objective was to evaluate the number and 12-h clock locations of arterial ligatures necessary to achieve Doppler silence. Results: In total, 146 patients were included: 111 (76%) men, and 35 (24%) women. Average age was 54 years (21–84). Grade III and grade IV haemorrhoids were diagnosed in 106 (72.6%) and 40 (27.4%) patients, respectively. The average number of ligatures per patient was 7 (range 2–12). Ligature percentages greater than 60% occurred at clock positions 7, 11, 10, 12, 9, and 1. The average number of mucopexies per patient was 3 (range 1–4). The most frequent mucopexy locations were the left posterior, right posterior, and right anterior octants. Conclusions: While the greatest frequency of arterial ligatures occurred in odd-numbered clock positions, non-negligible percentages occurred in even-numbered clock positions, which, in our opinion, makes the use of Doppler necessary, given that arterial distribution is not the same in all patients. We also noted that more ligatures and mucopexies were needed on the right half of the rectal circumference than on the left side, suggesting greater right-side vascularization.(AU)

Introducción: Aunque la desarterialización hemorroidal y mucopexia es técnica aceptada como alternativa válida a la hemorroidectomía, existen divergencias en lo que se refiere a una localización fija o variable de las arterias a ligar. Nuestro objetivo ha sido arrojar luz sobre esta cuestionada distribución arterial en pacientes quirúrgicos. Métodos: Se han incluido consecutivamente pacientes con diagnóstico de hemorroides de III y IV grado operados mediante desarterialización hemorroidal guiada por Doppler (D-HAL) y reparación rectoanal (RAR) en dos centros hospitalarios españoles. El principal objetivo fue evaluar el número necesario de ligaduras arteriales y su localización horaria para conseguir un silencio Doppler. Resultados: Se han incluido consecutivamente 146 pacientes, 111 (76%) varones y 35 (24%) mujeres, con una media de edad de 54 años (21–84), 106 (73%) fueron diagnosticados como grado III y 40 (27%) como grado IV. La media de ligaduras por paciente fue de 7 (2–12). Se encontraron porcentajes de ligaduras superiores al 60% en las posiciones horarias 7, 11, 10, 12, 9 y 1. La media de mucopexias por paciente fue 3 (1–4), siendo las localizaciones más frecuentes los octantes posterior izquierdo, posterior derecho y anterior derecho. Conclusiones: Aunque los puntos horarios impares son los de mayor frecuencia de localización arterial, porcentajes no despreciables de localización ocurren en las posiciones pares lo que, en nuestra opinión, hace que el uso del Doppler sea necesario dado que la distribución arterial no es constante en todos los pacientes. Hemos podido constatar también que en la semicircunferencia derecha han sido necesarias más ligaduras y pexias que en el lado izquierdo, lo que sugiere una mayor vascularización derecha.(AU)
