Insights
A new sclerosing agent, OC-108, offers a less invasive treatment for prolapsing internal hemorrhoids, showing similar prolapse disappearance rates to surgery but with fewer side effects.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Pharmacological Treatments
Background:
- Prolapsing internal hemorrhoids are a common condition.
- Traditional surgical treatments like ligation and excision carry risks of pain and bleeding.
- A novel sclerosing agent, OC-108, was developed for hemorrhoid treatment.
Purpose of the Study:
- To evaluate the efficacy and safety of OC-108 for treating prolapsing internal hemorrhoids.
- To compare OC-108 treatment outcomes with traditional surgical interventions.
Main Methods:
- A comparative study involving patients aged 20 years and older with prolapsing internal hemorrhoids.
- Treatment groups included the novel sclerosing agent OC-108 and conventional surgery (ligation and excision).
- Data collected from ten Japanese medical institutions between October 2000 and October 2002.
Main Results:
- At 28 days, prolapse disappearance rates were comparable: 94% for OC-108 versus 99% for surgery.
- The 1-year recurrence rate was 16% for OC-108, which is considered satisfactory given its less invasive nature, compared to 2% for surgery.
- Patients treated with OC-108 experienced significantly lower incidences of pain and bleeding.
Conclusions:
- OC-108 presents a viable and less invasive alternative treatment option for patients with prolapsing internal hemorrhoids.
- The agent demonstrates comparable efficacy in prolapse resolution with improved safety profile regarding pain and bleeding.
Background And Aims:
Patients with prolapsing internal hemorrhoids were treated with a novel sclerosing agent (OC-108), and the results were compared with surgery of ligation and excision.
Patients And Methods:
This study included 20 years or older patients with prolapsing internal hemorrhoids who visited ten medical institutions in Japan from October 2000 to October 2002. Investigation on surgery was also performed.
Results:
Comparing OC-108 and surgery in patients with third- and fourth-degree internal hemorrhoids according to the Goligher's classification, for which surgery has been generally indicated, at 28 days after treatment, the disappearance rate of prolapse was similar between OC-108 and surgery, 94% (75/80 patients) and 99% (84/85 patients), respectively. The 1-year recurrence rate was 16% (12/73 patients) in the OC-108 group, and this value was satisfactory because of its less invasive nature while it was more or less higher compared with 2% (2/81 patients) in the surgery group. The incidences of pain and bleeding were lower in the OC-108 group.
Conclusions:
OC-108 is a useful alternative treatment for hemorrhoids.
