ICD-10: K51.312

Ulcerative rectosigmoiditis, classified under ICD-10 code K51.312, is a specific form of inflammatory bowel disease (IBD) that primarily affects the rectum and sigmoid colon. This condition is characterized by chronic inflammation and ulceration of the intestinal mucosa, leading to various clinical presentations, signs, symptoms, and patient characteristics.

Clinical Presentation

Definition and Overview

Ulcerative rectosigmoiditis is a subtype of ulcerative colitis, which is a chronic inflammatory condition of the gastrointestinal tract. The "chronic" designation indicates that the condition persists over time, often with periods of exacerbation and remission. The addition of "with intestinal obstruction" signifies that the inflammation has led to a narrowing of the intestinal lumen, which can impede the passage of stool and other contents.

Signs and Symptoms

Patients with K51.312 may present with a range of symptoms, including:

• Abdominal Pain: Often crampy and located in the lower abdomen, pain may worsen with bowel movements.
• Diarrhea: Frequent, often bloody diarrhea is a hallmark symptom, with stools that may contain mucus or pus.
• Tenesmus: A sensation of incomplete evacuation after a bowel movement, leading to straining and discomfort.
• Weight Loss: Due to malabsorption and reduced appetite, patients may experience significant weight loss.
• Fatigue: Chronic inflammation can lead to fatigue and a general feeling of malaise.
• Fever: Some patients may experience low-grade fever during flare-ups.
• Signs of Intestinal Obstruction: Symptoms such as severe abdominal distension, vomiting, and inability to pass gas or stool may indicate an obstruction.

Patient Characteristics

Certain demographic and clinical characteristics are commonly associated with ulcerative rectosigmoiditis:

• Age: The onset typically occurs in young adults, often between the ages of 15 and 30, but it can occur at any age.
• Gender: There is a slight male predominance in the incidence of ulcerative colitis.
• Family History: A family history of inflammatory bowel disease may increase the risk of developing ulcerative rectosigmoiditis.
• Ethnicity: Higher prevalence is observed in individuals of Ashkenazi Jewish descent, although it can affect any ethnic group.
• Comorbidities: Patients may have other autoimmune conditions, such as rheumatoid arthritis or primary sclerosing cholangitis, which are associated with IBD.

Diagnosis and Management

Diagnosis typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Colonoscopy with biopsy is the gold standard for confirming the diagnosis and assessing the extent of the disease. Fecal calprotectin testing may also be utilized to evaluate intestinal inflammation.

Management of ulcerative rectosigmoiditis with intestinal obstruction often requires a multidisciplinary approach, including:

• Medications: Anti-inflammatory drugs, immunosuppressants, and biologics (e.g., anti-TNF agents) are commonly used to control inflammation and induce remission.
• Nutritional Support: Patients may require dietary modifications or nutritional supplements to address malnutrition.
• Surgery: In cases of severe obstruction or complications such as perforation, surgical intervention may be necessary, which could involve colectomy or other procedures.

Conclusion

Ulcerative rectosigmoiditis with intestinal obstruction (ICD-10 code K51.312) presents a complex clinical picture characterized by chronic inflammation of the rectum and sigmoid colon, leading to significant gastrointestinal symptoms and potential complications. Understanding the clinical presentation, signs, symptoms, and patient characteristics is crucial for timely diagnosis and effective management of this condition. Regular follow-up and monitoring are essential to manage flare-ups and maintain the patient's quality of life.
