Hemorrhoids are a prevalent anorectal condition that affects a wide range of adult populations. The severity of this condition was graded using a validated hemorrhoidal grading system, specifically focusing on grade III and IV cases. This retrospective study aimed to compare the clinical efficacy of a standard Procedure for Prolapse and Hemorrhoids (PPH) with a combined Doppler-guided Hemorrhoidal Artery Ligation (DG-HAL) and a PPH approach in patients with severe hemorrhoids. Conducted from May 2021 to January 2023, the study included patients aged 18–65 with confirmed diagnosis of Grade III or Grade IV hemorrhoids. Patients with a history of anorectal surgery and significant comorbidities were excluded. The control group underwent standard PPH, whereas the observation group received DG-HAL followed by PPH. Clinical outcomes were measured using variables such as the operative duration, intraoperative blood loss, postoperative wound healing time, and length of hospital stay. Efficacy was evaluated using a hierarchical scale and a visual analog scale (VAS) for postoperative pain. The complication rates were also assessed. baseline characteristics were homogeneous between the 2 groups. The observation group demonstrated significantly faster postoperative wound healing and shorter hospital stay (P < .01). The overall therapeutic efficacy in the observation group was 90.0%, which was higher than that of the control group (75.0%; P = .025). The VAS pain scores were also significantly lower in the observation group (P = .002). A marked decrease in complication rates was observed in the observation group (3.3%) compared with that in the control group (17.9%) (P < .05). The combined DG-HAL and PPH surgical approach exhibited superior clinical efficacy in treating severe hemorrhoids. This technique offers high effectiveness, reduced postoperative VAS pain scores, and lower complication rates. The long-term efficacy requires further observation.
