Frequently Asked Questions

Answers to the Most Common Questions About Colorectal Surgery in Los Angeles

What conditions does Dr. Zaghiyan treat?

Dr. Zaghiyan specializes in advanced, minimally invasive treatment for colorectal cancer, inflammatory bowel disease (Crohn’s disease and ulcerative colitis), rectal prolapse, hemorrhoids, anal fissures, fistulas, and complex pelvic floor disorders.

How do I know if I should see a colorectal surgeon instead of a gastroenterologist?

A colorectal surgeon is appropriate when symptoms persist despite medical management, when a structural or surgical issue is suspected, or when advanced evaluation or minimally invasive surgery may be needed.

What makes Dr. Zaghiyan one of the best colorectal surgeons in Los Angeles?

She is nationally recognized for her expertise in minimally invasive and transanal surgery, leadership roles at Cedars-Sinai, award-winning research, and her commitment to personalized, patient-centered care.

What types of minimally invasive surgery does Dr. Zaghiyan offer?

She performs robotic, laparoscopic, transanal (TAMIS/taTME), and natural orifice procedures designed to reduce pain, shorten recovery time, and improve long-term outcomes.

What should I expect at my first appointment?

You’ll discuss your symptoms, medical history, and prior testing. Dr. Zaghiyan personally reviews all imaging and creates a treatment plan tailored to your needs.

What imaging or records should I upload before my telehealth or in-person visit?

Patients should submit prior colonoscopies, CT/MRI scans, pathology reports, and any relevant notes from gastroenterologists or primary-care providers.

Does Dr. Zaghiyan offer second opinions?

Yes. She provides in-depth second opinions, both in person and via telehealth, for patients seeking expert guidance, reassurance, or advanced treatment options.

Does Dr. Zaghiyan participate in clinical trials?

Yes. As a national research leader, Dr. Zaghiyan offers access to ongoing colorectal and minimally invasive surgery clinical trials as they become available throughout the year.

How long does it take to get an appointment?

Wait times vary depending on the urgency of your condition. Priority scheduling is available for cancer, severe symptoms, or time-sensitive cases.

What is the difference between a telehealth consultation and an in-person visit?

Telehealth is ideal for second opinions and initial reviews of imaging. In-person visits allow for physical examination, additional testing, and preparation for surgery if needed.

How much does a second-opinion telehealth consultation cost?

Fees vary based on case complexity. Patients pay directly, and HSA/FSA funds may be used when applicable.

How do I prepare for surgery with Dr. Zaghiyan?

You’ll receive detailed preoperative instructions, including dietary guidelines, medication adjustments, bowel preparation (if needed), and postoperative planning.

What is the typical recovery time after minimally invasive colorectal surgery?

Recovery times differ by procedure, but many patients resume light activity within days and normal routines within two to four weeks.
