Colon Proctological and Pelvic Surgery at Aventino Medical Group
What does Colonproctological and Pelvic Surgery treat?
Colonproctological and Pelvic Surgery deals with the prevention, diagnosis, and treatment of pathologies affecting the colon, rectum, anus, and pelvic floor. This specialty is essential for treating disorders that can compromise quality of life, such as hemorrhoids, anal fistulas, fecal incontinence, and colon-rectal neoplasms, as well as for managing pelvic floor pathologies, including urinary incontinence, pelvic organ prolapse, and pelvic floor dysfunctions.
Our team of colon proctological surgeons at Aventino Medical Group offers a wide range of therapeutic solutions, which include both medical and surgical therapies. We use minimally invasive and cutting-edge techniques, ensuring a personalized approach focused on the patient’s well-being.

- Persistent intestinal disorders, such as chronic constipation or prolonged diarrhea
- Rectal bleeding or traces of blood in the stool
- Anal or perianal pain

Diagnostic and therapeutic approach
The diagnosis and treatment of colon proctological and pelvic floor pathologies involve a multidisciplinary and personalized approach. Our team uses the most modern technologies to ensure an accurate assessment of the patient.
Diagnostic Examinations
Specialist consultation with rectal examination
Anoscopy and proctoscopy for the direct visualization of anorectal structures
Transanal and transperineal ultrasound for the evaluation of the pelvic floor
Anorectal manometry to study the functionality of the anal sphincter
Defecography for the analysis of evacuative dynamics
Colonoscopy for the diagnosis of colon and rectum pathologies
Available Treatments
Pharmacological therapies for the control of inflammation and pain
Injections and nerve blocks for the treatment of chronic pelvic pain
Pelvic floor rehabilitation with specific physiotherapy
Minimally invasive surgery with laser, laparoscopic, and robotic techniques for the treatment of rectal prolapse and other conditions
How to prevent Colonproctological and Pelvic Pathologies?
A fiber-rich diet to regulate intestinal transit
Adequate hydration to prevent constipation
Regular physical activity to promote intestinal motility
Periodic screening after the age of 50 or in the presence of a family history of colon-rectal tumors
Attention to persistent symptoms such as bleeding or anal pain


Diagnostic and therapeutic approach
When is it necessary to undergo a colonoscopy?
It is recommended after the age of 50 as a preventive screening or in case of specific symptoms (blood in the stool, abdominal pain, changes in bowel habits).
Are hemorrhoid procedures painful?
Thanks to minimally invasive techniques, post-operative pain is reduced and recovery is quicker.
Can fecal incontinence be treated without surgery?
There are rehabilitative, pharmacological, and minimally invasive treatments that can improve bowel control.
How is chronic pelvic pain treated?
✔ Treatment involves a multidisciplinary approach with pharmacological therapy, pelvic floor rehabilitation, and, in some cases, minimally invasive surgical interventions.
When does the doctor recommend a defecography, and what should I expect during the exam?
Defecography is recommended in cases of chronic constipation, difficulty with bowel movements, incomplete evacuation sensation, or rectal prolapse. During the exam, a contrast agent is gently introduced into the rectum, and the patient, seated on a special radiolucent toilet, is asked to simulate defecation.
The exam lasts about 15 minutes, is minimally invasive, and helps assess the pelvic floor function, guiding the most appropriate treatment
