K35.201
Acute appendicitis with generalized peritonitis, with perforation, without abscess
Clinical Classification Guidelines
Inclusion Terms
- Appendicitis (acute) with generalized (diffuse) peritonitis following rupture or perforation of appendix NOS
Medical Intelligence & Overview
Acute appendicitis with generalized peritonitis is a serious medical condition that occurs when the appendix becomes inflamed and ruptures, leading to widespread infection throughout the abdominal cavity. This condition is classified under ICD-10 code K35.201. It requires prompt diagnosis and treatment to prevent further complications. Recognizing the signs and understanding the causes can help in seeking timely medical attention.
Causes & Symptoms
Clinical Causes: Obstruction of the appendix lumen, often by a fecalith (hardened stool), enlarged lymphoid tissue, or foreign bodies Infection leading to inflammation of the appendix tissue Delayed treatment of initial appendicitis, resulting in rupture Increased intraluminal pressure causing ischemia and subsequent perforation Anatomical variations in the appendix that predispose to rupture
Key Symptoms: Sudden onset abdominal pain, typically starting near the navel and migrating to the lower right abdomen Signs of generalized peritonitis such as diffuse abdominal tenderness, rigidity, and guarding Fever and chills indicating systemic infection Nausea and vomiting Loss of appetite Feeling unwell or malaise Signs of shock in severe cases, including rapid heartbeat and low blood pressure
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess abdominal tenderness, rigidity, and rebound tenderness Blood tests showing elevated white blood cell count and markers of infection Imaging studies like ultrasound and computed tomography (CT) scan to visualize the appendix rupture, free fluid, or signs of peritonitis Peritoneal fluid analysis if punctured or aspirated during diagnostics
Treatment Protocols: Emergency appendectomy — surgical removal of the ruptured appendix Peritoneal lavage — cleaning the abdominal cavity to remove infectious material Administration of broad-spectrum antibiotics to control infection Intravenous fluids to manage dehydration and stabilize vital signs Monitoring for complications such as sepsis or abscess formation
