RESUMEN
BACKGROUND: Tuberculous appendicitis is a rare extrapulmonary manifestation of tuberculosis without clear summarization or consensus on its management. DATA SOURCES: Case reports were gathered from several online literature databases by searching terms "tuberculosis", "tuberculous", and "appendicitis".Report eligibility criteria: Cases of appendicitis due to M. tuberculosis identified on operative histology. Exclusion criteria: appendicitis caused by a mycobacterium other than M. tuberculosis, and appendiceal tuberculosis identified incidentally during procedures for other reasons. RESULTS: Thirty four patients were identified. Twenty five patients presented with acute right lower quadrant abdominal pain. Eleven patients described chronic symptoms of tuberculosis (cough, night sweats, or weakness/fatigue). Four patients had a known diagnosis of TB. Seven of 24 cases reported peri-operative chest imaging which demonstrated pulmonary lesions. AFB were present in tissue or fluid samples of 6 patients, and negative in 15 patients. All patients underwent pharmacotherapy on a WHO-recommended anti-tuberculous treatment (ATT) with RIPE or an alternative. The average duration of treatment was 7.2 ± 1.7 months. LIMITATIONS: Data was gathered from case reports without complete uniformity in diagnostic work-up. The potential for larger scale study is limited due to disease rarity. CONCLUSIONS: Tuberculous appendicitis cannot be diagnosed prior to histologic evaluation. Several data points may suggest the disease on a clinician's differential diagnosis if they present with a combination of the following: born in a country with endemic tuberculosis; chronic cough, weakness/fatigue, or nausea prior to onset of abdominal pain; pulmonary lesions on chest X-ray; white studding of the mesentery or peritoneum in a young patient; positive AFB stain of abdominal fluid or peritoneal tissue.
RESUMEN
BACKGROUND: Gastrointestinal tuberculosis (TB) accounts for 3% of extrapulmonary TB. Tuberculous appendicitis is a rare type of abdominal TB and is seen in only 0.1%-0.3% of cases. Diagnosis is usually made after histopathologic examination of the appendectomy specimen. In Ethiopia, there had been no previous report of perforated appendicular TB, and to our knowledge, this is the first case report of a patient with perforated tuberculous appendicitis to be presented. CASE REPORT: A 22-year-old male patient presented with complaints of severe abdominal cramp, periumbilical pain, nausea, 2 episodes of nonbilious vomiting, as well as high-grade fever. Upon admission, abdominal examination revealed direct tenderness below the umbilicus bilaterally and rebound tenderness over the right lower quadrant of the abdomen. The peritoneal cavity was opened through a lower midline incision, and a perforated appendix at the base was found. DISCUSSION: From the resected appendix, a sample biopsy was sent for histopathology, and the histological picture revealed granulomatous caseification lesion in the body of the appendix, but no granulomatous lesions elsewhere in the bowel or omentum. Based on these findings, the final diagnosis of perforated tuberculous appendicitis was made. After surgery, the patient started anti-TB treatment on the fourth postoperative day and continued therapy for 6 months, and marked clinical recovery has been observed to date. CONCLUSION: Perforated tuberculous appendicitis was diagnosed only after histopathologic examination of the resected appendix. Hence, TB, a highly prevalent disease in low-income countries, should always be considered in patients with nonspecific abdominal clinical sign and symptoms. It is also suggested that all specimens from perforated appendicitis be subjected to histopathologic examination.
RESUMEN
PURPOSE: This paper provides an overview of the literature on appendicular tuberculosis (ATB) between 1909 and 2010. METHODS: We present two cases of primary ATB and a literature review of studies on ATB published in English and accessed via the Pubmed and Google Scholar databases. RESULTS: One hundred fifty-five published cases of ATB were reviewed, and two patients with primary ATB, treated and followed in our clinic, were reported. The age range of the patients (62 females, 60 males and 33 with unnoted gender) was between 2 and 60 years, with a mean age of 27.1 ± 10.6 years. Of the patients who had applied to hospital, 59 had acute right lower quadrant pain, 46 had recurrent right lower quadrant pain, 19 had generalized pain, and 10 had chronic abdominal symptoms suggestive of subacute intestinal obstruction, while 47 patients were operated on with a diagnosis of acute appendicitis, 24 with recurrent appendicitis, 19 with TB peritonitis, 14 with mass in the right lower quadrant, 13 with subacute intestinal obstruction, and 7 with ATB. While appendectomy was not performed on 4 patients, one or more of the following procedures were done in the other 151 cases: appendectomy, hemicolectomy, ileocecal resection, or cecectomy. Different anti-tubercular treatment regimens with durations varying from 3 weeks to 18 months were applied to 60 patients. During the follow-up period of 3 weeks to 15 years, mortality occurred in 14 patients, sinus in five, and fistula in one patient. Secondary ATB was detected in 86 patients, primary ATB in 50, and no differential diagnosis could be made in 19 cases. CONCLUSIONS: Tuberculosis is a systemic disease with localized manifestations; therefore, anti-TB therapy must be initiated in any patient whose pathologic specimen reveals tuberculosis.
