Stage IIB characteristics are as follows:

  • Patient is moderately ill

  • Diagnosis requires all of stage I signs plus the systemic signs of moderate illness, such as mild metabolic acidosis and mild thrombocytopenia

  • Abdominal examination reveals definite tenderness, perhaps some erythema or other discoloration, and/or right lower quadrant mass

  • Radiographs show portal venous gas with or without ascites
