Delayed Diagnosis of Crohn's Disease & Ulcerative Colitis in NY

What Are Crohn's Disease and Ulcerative Colitis?

Inflammatory bowel disease (IBD) is a group of chronic conditions that cause inflammation of the digestive tract. The two main types are:

Crohn's disease: - Can affect any part of the digestive tract — from the mouth to the anus. - Most commonly affects the end of the small intestine (terminal ileum) and the beginning of the colon. - Inflammation occurs in patches — with areas of normal tissue between inflamed areas. - Can extend through the entire thickness of the bowel wall — leading to complications like fistulas (abnormal connections between organs), abscesses, and strictures (narrowing of the bowel). - There is no cure — treatment focuses on controlling inflammation and preventing complications.

Ulcerative colitis: - Affects only the colon (large intestine) and rectum. - Inflammation is continuous — starting from the rectum and extending up the colon. - Affects only the innermost lining of the colon (mucosa) — not the full thickness of the bowel wall. - Also has no cure — treatment focuses on controlling inflammation and preventing complications.

Symptoms of IBD: - Abdominal pain and cramping. - Diarrhea — may be bloody in ulcerative colitis. - Weight loss and loss of appetite. - Fatigue. - Fever — during flare-ups or complications. - Rectal bleeding — blood in the stool. - Joint pain — IBD can affect joints (arthritis). - Skin rashes and eye inflammation — IBD can affect other organs.

IBD is a progressive disease — without treatment, the inflammation causes increasing damage to the digestive tract, leading to serious complications. Early diagnosis and treatment are essential to prevent complications and improve quality of life.

Why IBD Is Frequently Delayed in Diagnosis

Crohn's disease and ulcerative colitis are frequently delayed in diagnosis for several reasons:

• Non-specific symptoms: Abdominal pain, diarrhea, and weight loss are symptoms of many conditions — making it easy to attribute them to more common causes.
• Attribution to irritable bowel syndrome (IBS): IBS is far more common than IBD — and has similar symptoms (abdominal pain, diarrhea). Providers may diagnose IBS without performing the tests needed to rule out IBD.
• Attribution to dietary issues: Symptoms may be attributed to food intolerance, celiac disease, or dietary changes — without adequate evaluation.
• Attribution to infections: Acute symptoms may be attributed to gastroenteritis or food poisoning — without considering chronic conditions.
• Attribution to stress or anxiety: Abdominal pain and diarrhea may be attributed to stress or anxiety — particularly in younger patients.
• Failure to perform colonoscopy: Colonoscopy with biopsy is the gold standard for diagnosing IBD. Failure to perform colonoscopy when IBD is suspected — or when symptoms persist despite treatment for presumed IBS — is a common error. [Link to: /misdiagnosis/colonoscopy-failure]
• Failure to order lab tests: Blood tests (CBC, inflammatory markers like CRP and ESR, iron studies) and stool tests (calprotectin, occult blood, infection testing) can support the diagnosis of IBD. Failure to order these tests may delay the diagnosis.
• Dismissal of symptoms: Particularly in young women — providers may dismiss abdominal symptoms as functional or psychological without adequate evaluation.
• Failure to refer to a gastroenterologist: IBD requires specialist management. Failure to refer to a gastroenterologist may delay the diagnosis and appropriate treatment.

Common Misdiagnoses

Crohn's disease and ulcerative colitis are commonly misdiagnosed as:

• Irritable bowel syndrome (IBS): The most common misdiagnosis. IBS is a functional disorder — it does not cause inflammation, bleeding, weight loss, or the complications of IBD. Key distinguishing features: IBS does not cause rectal bleeding, significant weight loss, fever, or abnormal lab tests (elevated CRP, anemia).
• Gastroenteritis: Acute diarrhea and abdominal pain may be attributed to a stomach bug — without considering chronic conditions.
• Food intolerance or allergy: Celiac disease, lactose intolerance, or other dietary issues.
• Hemorrhoids: Rectal bleeding may be attributed to hemorrhoids — without performing colonoscopy to rule out IBD or colorectal cancer. [Link to: /misdiagnosis/colon-cancer-misdiagnosis]
• Stress or anxiety: Particularly in younger patients.
• Celiac disease: Another chronic condition that causes similar symptoms.
• Diverticulitis: Inflammation of diverticula (small pouches in the colon) — can mimic IBD symptoms.
• Appendicitis: Acute Crohn's flare in the terminal ileum can mimic appendicitis. [Link to: /misdiagnosis/appendicitis]

The Standard of Care for Diagnosing IBD

The standard of care for diagnosing Crohn's disease and ulcerative colitis is established by the American Gastroenterological Association (AGA), the American College of Gastroenterology (ACG), and the European Crohn's and Colitis Organisation (ECCO). Key elements include:

1. Thorough history and physical examination: Assessing symptoms, duration, progression, family history (IBD has a genetic component), and extraintestinal manifestations (joint pain, skin rashes, eye inflammation).

2. Recognizing red flag symptoms that require further evaluation: - Rectal bleeding — blood in the stool - Significant weight loss - Fever - Nocturnal symptoms — waking from sleep to have bowel movements (suggests organic disease, not IBS) - Abnormal lab tests — anemia, elevated inflammatory markers (CRP, ESR) - Family history of IBD - Symptoms that persist despite treatment for presumed IBS or other conditions

3. Lab tests: Complete blood count (CBC — looking for anemia), inflammatory markers (CRP, ESR — elevated in IBD), iron studies, and stool tests (calprotectin — elevated in intestinal inflammation; occult blood; infection testing).

4. Colonoscopy with biopsy: The gold standard for diagnosing IBD. Allows direct visualization of the colon and terminal ileum, identification of characteristic findings (inflammation, ulcers, pseudopolyps), and biopsy for pathological confirmation. The standard of care requires colonoscopy when IBD is suspected — or when symptoms persist despite treatment for presumed IBS. [Link to: /misdiagnosis/colonoscopy-failure]

5. Upper endoscopy: If upper GI symptoms are present — Crohn's can affect the stomach and duodenum.

6. Imaging: CT or MRI of the abdomen may show bowel wall thickening, inflammation, or complications (abscess, fistula, obstruction). Capsule endoscopy can visualize the small intestine — which is not reachable by standard colonoscopy or endoscopy.

7. Referral to a gastroenterologist: IBD requires specialist management — the standard of care requires referral to a gastroenterologist for diagnosis and treatment.

When Delayed Diagnosis Constitutes Negligence

A delayed diagnosis of Crohn's disease or ulcerative colitis constitutes medical malpractice when:

- The provider attributed symptoms to IBS without performing the tests needed to rule out IBD — particularly when red flag symptoms (rectal bleeding, weight loss, abnormal labs) were present. - The provider failed to perform colonoscopy when IBD was suspected or when symptoms persisted despite treatment. [Link to: /misdiagnosis/colonoscopy-failure] - The provider failed to order lab tests — CBC, inflammatory markers, stool studies — that would have supported the diagnosis. [Link to: /delayed-diagnosis-lawyer/failure-to-order-tests] - The provider dismissed rectal bleeding as hemorrhoids without performing colonoscopy. [Link to: /misdiagnosis/colon-cancer-misdiagnosis] - The provider failed to refer to a gastroenterologist when the condition required specialist evaluation. - The provider failed to recognize red flag symptoms — weight loss, nocturnal symptoms, abnormal labs, family history. - The provider failed to reassess when the patient's symptoms did not improve with treatment for presumed IBS or other conditions.

To prove malpractice, expert testimony from a gastroenterologist is required.

Consequences of Delayed Treatment

When IBD is not diagnosed and treated promptly, the disease progresses — causing serious complications:

• Bowel obstruction: Chronic inflammation causes scarring and narrowing (strictures) of the bowel — leading to obstruction that may require surgery.
• Bowel perforation: Severe inflammation can cause a hole in the bowel wall — a life-threatening emergency requiring emergency surgery.
• Fistulas: Abnormal connections between the bowel and other organs (bladder, vagina, skin) — caused by inflammation extending through the full bowel wall. Particularly common in Crohn's disease.
• Abscesses: Collections of pus in the abdomen — requiring drainage and antibiotics.
• Malnutrition: Chronic inflammation impairs nutrient absorption — causing weight loss, vitamin deficiencies, and osteoporosis.
• Increased cancer risk: Long-standing IBD (particularly ulcerative colitis) increases the risk of colorectal cancer — the risk increases with the duration and extent of disease. [Link to: /misdiagnosis/colon-cancer-misdiagnosis]
• Toxic megacolon: A life-threatening complication of ulcerative colitis — the colon dilates massively and may rupture. Requires emergency surgery.
• Surgery: Delayed treatment may lead to the need for bowel resection — surgical removal of portions of the intestine. In severe ulcerative colitis, a total colectomy (removal of the entire colon) may be needed — sometimes with a permanent ostomy.
• Permanent disability: Chronic disease, surgical complications, and ostomy can significantly impact quality of life and ability to work.

Proving Causation in IBD Cases

Proving that the delayed diagnosis caused the patient's harm requires establishing:

1. The standard of care was breached: Expert testimony that the provider failed to perform colonoscopy, failed to order lab tests, attributed symptoms to IBS without adequate evaluation, or failed to refer to a gastroenterologist.

2. Earlier diagnosis and treatment would have prevented or reduced the harm: Expert testimony that prompt diagnosis and treatment (medications to control inflammation, monitoring for complications) would have prevented the strictures, fistulas, perforation, or surgery.

3. The delay was a substantial factor in causing the harm: The patient's complications (obstruction, perforation, fistulas, surgery) would not have occurred, or would have been less severe, if IBD had been diagnosed and treated promptly.

The defense may argue that IBD is difficult to diagnose, that the symptoms were non-specific, or that the complications would have occurred regardless. Expert testimony is required to counter these arguments. [Link to: /misdiagnosis/differential-diagnosis]

New York Statute of Limitations

Under CPLR § 214-a, the statute of limitations is 2.5 years from the date of the delayed diagnosis. The continuous treatment doctrine may extend the deadline if you continued receiving treatment from the same provider for the same condition — which is common in IBD cases, where patients may see the same doctor for years. Lavern's Law may apply if colorectal cancer developed from long-standing undiagnosed IBD — 2.5 years from discovery, with a 7-year outer limit.
