Introduction of Rectal Polyps

Model:Colonoscopy Simulator (ZJC-01)

Rectal polyps are common gastrointestinal conditions that refer to protruding lesions from the rectal mucosa into the intestinal lumen. Until the pathological type is determined, they are collectively referred to as polyps. Depending on the pathological type, these can be categorized as: 1) Adenomatous polyps, which include tubular adenomas, villous adenomas, and tubulovillous adenomas, and 2) Non-adenomatous polyps, which comprise inflammatory polyps, hyperplastic polyps, and hamartomatous polyps. Clinical symptoms of rectal polyps primarily manifest as rectal bleeding, with a higher proportion of patients with adenomatous or juvenile polyps larger than 1.0 cm, and those with polyps at risk of cancer, experiencing rectal bleeding. Apart from rectal bleeding, abdominal pain, diarrhea, and mucus in stools are also clinical manifestations of rectal polyps.

Do rectal polyps require surgery?

In cases where inflammatory polyps are caused by intestinal infections, and if the polyps are small or asymptomatic, surgery may not be necessary. Anti-inflammatory treatments and colon cleansing can be administered, and after the inflammation subsides, some inflammatory polyps may disappear. Regular follow-up visits to the outpatient clinic for rectoscopy to monitor the condition are recommended. For tumor-like polyps or polyps larger than 2 cm, early surgical removal is advised upon detection, as the risk of cancer transformation gradually increases with the continued growth of most polyps. The decision on whether rectal polyps require surgery depends on the type, size, and quantity of the polyps. Since the introduction of electronic colonoscopy in clinical diagnosis and treatment, there has been a significant advancement in the understanding and treatment methods for rectal polyps. In the era of highly developed minimally invasive surgeries, rectal polyps can be easily addressed through minor procedures. The treatment method varies based on the nature of the polyps. Polyps with stalks or those without can be successfully removed using methods such as snare electrocautery or hot biopsy forceps under direct visualization with an electronic colonoscope, resulting in high success rates and favorable treatment outcomes.

How can rectal polyps be prevented?

Screening and prevention of rectal polyps in the early stages can effectively reduce the incidence of rectal cancer. Given the insidious onset of rectal cancer and the lack of obvious early symptoms, many patients are diagnosed in the advanced stages. Therefore, promoting early diagnosis and treatment is crucial for preventing cancer transformation and improving survival rates. Dietary factors and lifestyle habits have been a focal point in studies on the relationship between rectal polyps and tumors. To prevent the occurrence of polyps at the source, maintaining intestinal health through daily habits is essential. Factors like smoking, alcohol consumption, obesity, high-fat diets, and excessive intake of red meat significantly increase the likelihood of rectal polyps. Conversely, a low-protein diet, increased intake of vegetables and fruits, and regular physical activity can reduce the probability of developing rectal polyps to a certain extent.

The Colonoscopy Simulator offers a comprehensive training experience for medical professionals and students, designed to simulate realistic colonoscopy procedures. This innovative training model encompasses key segments of the colon, including the cecum, ileum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. Constructed using silicone material and advanced 3D printing technology based on CT data from Chinese adults, this simulator provides a true-to-life 1:1 representation of the colon, enhancing the training accuracy and realism.

Placed within a durable simulated abdominal cavity, the Colonoscopy Training Model replicates the spatial structure of the colon, offering a hands-on experience that closely mirrors actual clinical scenarios. The simulator serves a dual purpose, enabling users to practice colonoscopy pathway navigation as well as polypectomy procedures in a controlled and educational setting.

For enhanced customization and adaptability, the Colonoscopy Simulator offers a range of options to tailor the training experience to specific needs. Users have the flexibility to customize the dimensions of different colon segments, incorporate various colon lesions such as polyps for targeted training scenarios, and even adjust the color of the model to meet individual preferences or educational requirements. This versatility allows for a personalized training approach that aligns with diverse learning objectives and clinical practice settings.
