How to prepare for an emergency colonoscopy?
Colonoscopy is usually a routine screening or diagnostic procedure scheduled well in advance. However, our practice is fully equipped and prepared to perform urgent or emergency colonoscopies when patients face critical gastrointestinal issues.
In certain urgent medical situations, a colonoscopy becomes essential for prompt diagnosis and intervention. For example, patients experiencing significant gastrointestinal bleeding, severe abdominal pain suggesting bowel obstruction or perforation, or rapid changes in bowel habits indicating a serious underlying condition may require immediate attention. Our highly trained physicians utilize emergency colonoscopy procedures to rapidly identify and manage these critical conditions, ensuring optimal patient outcomes.
For acute gastrointestinal bleeding, our surgeons can urgently perform colonoscopies to pinpoint the exact source of the bleeding, enabling immediate intervention, whether through endoscopic therapies, medication administration, or planning timely surgical procedures. Similarly, when bowel obstruction or perforation is suspected, an emergency colonoscopy performed by Phoenix Unified Surgeons specialists can swiftly assist in accurate diagnosis and facilitate decisive treatment planning and interventions.
While emergency colonoscopies are less common, our practice emphasizes the importance of prompt diagnosis and effective intervention when immediate care is essential to stabilize patients and prevent severe complications. Phoenix Unified Surgeons remains committed to providing comprehensive, compassionate care, whether performing elective colonoscopies for routine screening and chronic symptom evaluation or rapidly responding to urgent and emergency gastrointestinal conditions.
One of the primary reasons our surgeons request an urgent colonoscopy is the presence of unexplained rectal bleeding. This is particularly important if the bleeding is significant, persistent, or accompanied by other concerning symptoms. Blood in the stool, ranging from bright red to dark and tarry, can indicate serious conditions such as inflammation, diverticulosis, polyps, or colorectal cancer.
Another common indication for urgent colonoscopy is anemia, particularly iron-deficiency anemia. This condition can often signify chronic blood loss from somewhere within the gastrointestinal tract. Additionally, if you experience sudden or persistent changes in bowel habits such as ongoing diarrhea, constipation, or narrower stools, our surgeons may recommend an urgent colonoscopy to rule out serious underlying conditions.
Our practice also prioritizes urgent colonoscopy for patients whose imaging studies or physical examinations reveal abnormalities, including suspicious polyps, masses, or strictures within the colon. Individuals with a family history of colorectal cancer or inflammatory bowel disease who suddenly develop concerning symptoms may also require prompt evaluation by our surgical specialists.
If you are experiencing significant abdominal pain, persistent bloating, or unexplained weight loss, an urgent colonoscopy performed by our skilled surgeons can help identify underlying conditions like inflammatory bowel disease (Crohn’s disease or ulcerative colitis), infections, or colorectal cancer. Early identification and treatment of these conditions are essential for preventing complications and achieving optimal patient outcomes.
At Phoenix Unified Surgeons, we believe an urgent colonoscopy is an essential diagnostic procedure that enables timely intervention, precise diagnosis, and personalized treatment plans—ultimately leading to better long-term health outcomes for our patients.
The fastest way to set up your procedure typically involves coordinating directly with your primary care physician or contacting our surgical specialists. Begin by reaching out to your doctor’s office and clearly explaining the urgency of your situation; they can expedite your referral to our team or connect you directly with our colorectal specialists, who are experienced in handling urgent medical evaluations.
Another effective approach is to contact Phoenix Unified Surgeons directly. Our practice maintains close relationships with accredited outpatient endoscopy centers and hospital-based digestive health facilities in the Phoenix area, allowing us greater flexibility in accommodating urgent procedures. Clearly communicating your symptoms and reasons for urgency such as troubling gastrointestinal symptoms, a family history of colon cancer, or recent abnormal test results, helps our surgical team prioritize your care appropriately.
Being flexible regarding your appointment’s date and time can further expedite scheduling. Completing all necessary paperwork and following the preparatory instructions provided by our surgeons promptly will also streamline your scheduling process. Our dedicated team will guide you every step of the way, ensuring you understand the preparation requirements clearly.
Additionally, we recommend verifying coverage and authorization with your insurance provider promptly, as this step can significantly reduce administrative delays. Our administrative staff can assist you in navigating insurance-related questions and paperwork to facilitate quicker scheduling and minimize stress. By proactively communicating your needs and collaborating closely with our experienced team, you can significantly expedite the colonoscopy scheduling process and receive the timely medical attention you deserve.
Preparing for an Emergency Colonoscopy at Phoenix Unified Surgeons
Emergency colonoscopy can be unexpected and stressful. Our experienced surgical team is committed to guiding you through each step, providing clear instructions and compassionate support to ensure the procedure is safe, effective, and comfortable.
Dietary Guidelines
After our surgeons determine that an emergency colonoscopy is necessary, you will receive detailed dietary instructions to ensure your colon is properly cleared. Typically, you will be instructed to stop eating solid foods for several hours or overnight, based on how urgently the procedure must be performed. Until the scheduled fasting period, we recommend consuming only clear liquids.
Bowel Preparation
To achieve the clearest visualization possible, your surgeon will prescribe a bowel-cleansing preparation or laxative. It is essential to follow these instructions carefully, consuming the provided solution within the specified timeframe. To improve the taste or reduce nausea, you may find it helpful to chill the solution or sip it through a straw.
Medication Management
Inform your surgeon and care team about any medications and dietary supplements you currently take, especially:
• Blood-thinning medications
• Insulin or diabetes medications
Our surgical team may advise temporary adjustments or discontinuation of these medications prior to your emergency colonoscopy procedure.
Medical History and Allergies
Please let the Phoenix Unified Surgeons team know about any allergies or pre-existing medical conditions, including:
• Heart disease
• Kidney disease
• Diabetes
• Pregnancy
Medication allergies
This information allows us to customize your care, manage underlying conditions, and take appropriate precautions during your colonoscopy.
Transportation and Post-Procedure Care
Because sedation is typically used during colonoscopy procedures, you must arrange transportation home afterward. We strongly advise against driving or making significant decisions for approximately 24 hours after the procedure, as sedation effects may linger.
Monitoring for Side Effects
If you experience significant discomfort, nausea, dizziness, or any adverse reactions during or after the bowel preparation, please promptly contact our team. We are here to assist you and address any concerns immediately.
At Phoenix Unified Surgeons, your safety, comfort, and peace of mind are our top priorities. Following these guidelines closely helps our surgical team perform your emergency colonoscopy successfully, allowing us to quickly diagnose and address your medical needs.
