Tuberculosis and the Acute Abdomen: An Evaluation of the National Inpatient Sample. Surgical infections Forrester, J. D., Cha, P., Tennakoon, L., Staudenmayer, K. 2019


Background: Tuberculosis can cause acute abdominal pathology requiring operation. While most cases of tuberculosis resolve with appropriate anti-mycobacterial therapy, a surgical procedure still may be required. We sought to describe the modern epidemiology of acute abdominal pathology associated with tuberculosis in the United States. Methods: We retrospectively analyzed the 2010-2014 National Inpatient Sample for admissions associated with International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for both tuberculosis and acute abdominal pain. Cases of acute abdominal tuberculosis were defined as inpatient admissions with a diagnosis of tuberculosis and a diagnosis of acute abdominal pain. Outcomes of interest included need for abdominal operation and death after operation. Adjusted analyses accounting for survey methodology were performed. Results: There were 66,034 inpatient admissions associated with tuberculosis of which 3638 (6%) included a diagnosis of acute abdominal pain. Among cases, 1578 (43%) were 45-64 years old and 2344 (64%) were male. Most patients were Hispanic (n=1090, 30%) or black (n=924, 25%) and were in the lowest quartile of income by zip code (n=1367, 38%). A total of 347 (0.5% of total) patients underwent an operation. Procedures included peritoneal biopsy (n=136, 39%), repair or resection of a hollow viscus (n=122, 35%), and abdominal exploration (n=111, 32%). In adjusted analysis, undergoing a surgical procedure was found to depend on the type of tuberculosis infection (odds ratio [OR]=1.17 for intestinal, peritoneal, or genitourinary tuberculosis versus other types, 95% confidence interval [CI]=[1.12-1.22]) and whether the patient was white or Asian race versus black and Hispanic (OR=1.11, 95% CI [1.02-1.21]). Thirty-nine (11%) of the 347 patients who underwent a surgical procedure died during hospitalization. Conclusions: An operation still may be required for patients with tuberculosis presenting with acute abdominal pain. Black and Hispanic patients are less likely to receive surgical intervention than whites or Asians. The inhospital deaths from acute abdominal pain necessitating operation among patients with tuberculosis are high.
