Non-traumatic ileal perforation: a retrospective study

Ileal Perforation and Enteric Fever: Implications for Burden of Disease Estimation

Background

Ileal perforation occurs in about 1% of enteric fevers as a complication, with a case fatality risk (CFR) of 20%–30% in the early 1990s that decreased to 15.4% in 2011 in South East Asia. We report nontraumatic ileal perforations and its associated CFR from a 2-year prospective enteric fever surveillance across India.

Methods

The Surveillance for Enteric Fever in India (SEFI) project established a multitiered surveillance system for enteric fever between December 2017 and March 2020. Nontraumatic ileal perforations were surveilled at 8 tertiary care and 6 secondary care hospitals and classified according to etiology.

Results

Of the 158 nontraumatic ileal perforation cases identified,126 were consented and enrolled. Enteric fever (34.7%), tuberculosis (19.0%), malignancy (5.8%), and perforation of Meckel diverticulum (4.9%) were the common etiology. In those with enteric fever ileal perforation, the CFR was 7.1%.

Conclusions

Enteric fever remains the most common cause of nontraumatic ileal perforation in India, followed by tuberculosis. Better modalities of establishing etiology are required to classify the illness, and frame management guidelines and preventive measures. CFR data are critical for comprehensive disease burden estimation and policymaking.

Coinfection of Typhoid Fever With Tuberculosis: A Challenge to Surgical Management

Ileal perforation is one of the most dreaded complications of abdominal tuberculosis. It is more common in immunodeficient patients, where ulcerative type of intestinal tuberculosis predominates. Various factors play role in the outcome of these patients, such as age and comorbid illness, though the lag period (advent of symptoms to time of admission to hospital) correlated directly to the mortality in these patients. Herein we present a 28-year-old male who had a coinfection of typhoid fever along with intestinal tuberculosis. The patient presented with abdominal pain and fever for one-week duration. On examination, he had diffuse tenderness of his abdomen with guarding. X-ray revealed free air under diaphragm. The patient underwent limited resection of terminal ileum and cecum with end ileostomy for ileal perforation. The patient’s serum Widal test was positive and blood culture grew Salmonella Typhi, and the patient was started on intravenous (IV) antibiotics based on culture and sensitivity. The patient’s general condition worsened after two weeks with bile leak from the surgical site. The patient succumbed to severe sepsis. Postoperative histopathology of the resected ileo-cecal segment showed features of ileo-cecal tuberculosis. As typhoid is a common cause of ileal perforation in the developing countries, the co-existence of typhoid fever in this patient lead to the delay in the diagnosis and appropriate management of tubercular ileal perforation. Knowledge about various causes of typhoid perforation is essential for treating surgeons.
