Frequently Asked Questions
Answers from Dr. Nasseri to the questions Los Angeles patients ask most.
Q.What makes Dr. Nasseri different from other colorectal surgeons in Los Angeles?
Dr. Nasseri is double board-certified in general and colorectal surgery and was selected by the da Vinci robotics company to train surgeons internationally. His practice also runs concierge-style: most patients are seen the same day or the next day.
Q.How soon can I get an appointment?
Usually within 24 hours. The practice reserves time for same-day and next-day consultations because surgical symptoms rarely wait. Call (424) 655-3312 to be seen quickly.
Q.What is robotic colorectal surgery?
Robotic surgery uses the da Vinci system to operate through small incisions with 3D visualization and instruments that move with more precision than the human wrist. Patients typically have less pain, shorter hospital stays, and faster recoveries than with open surgery.
Q.Is robotic surgery safe?
Yes — in expert hands, robotic colorectal surgery is associated with fewer complications, less blood loss, and faster recovery than traditional open surgery. Experience matters: Dr. Nasseri has performed and taught these procedures internationally.
Q.How long is recovery after robotic colon surgery?
Most patients walk the same day, go home within one to three days, and return to normal activity in two to four weeks — significantly faster than the six to eight weeks typical of open surgery.
Q.When should I see a doctor about rectal bleeding?
Any rectal bleeding deserves evaluation. While hemorrhoids are the most common cause, bleeding can also signal polyps, inflammatory bowel disease, or colorectal cancer. A prompt exam provides answers and peace of mind.
Q.Can hemorrhoids be treated without surgery?
Often, yes. Many hemorrhoids respond to office-based treatments such as rubber band ligation, dietary changes, and medical therapy. When surgery is needed, minimally invasive techniques keep discomfort and downtime low.
Q.At what age should I get a colonoscopy?
Screening now starts at age 45 for average-risk adults — earlier if you have a family history of colorectal cancer or symptoms like bleeding or a change in bowel habits.
Q.Do you treat both routine and complex conditions?
Yes. Dr. Nasseri treats everything from hemorrhoids, fissures, and pilonidal disease to complex Crohn’s disease, diverticulitis, and colon and rectal cancer.
Q.Do you offer second opinions?
Absolutely. Many patients see Dr. Nasseri for a second opinion before committing to major colorectal surgery — especially to ask whether a robotic, minimally invasive approach is possible in their case.
Q.Where is the office located?
At the Cedars-Sinai Medical Towers, 8635 West 3rd Street, Suite 880W, Los Angeles, CA 90048 — serving Beverly Grove, West Hollywood, Beverly Hills, and all of Los Angeles.
Q.Do you accept insurance?
Most PPO insurance plans are accepted, and the team verifies your benefits before your visit. The office can also provide superbills for out-of-network plans.
