Abstract:
To summarize the clinical features of pancreatic tuberculosis, analyze its endoscopic ultrasonography (EUS) findings, aspiration histopathology and etiological results, the medical history, clinical manifestations, laboratory tests, imaging findings, EUS findings, pathological and etiological results of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy, of 14 patients with pancreatic tuberculosis in Wuhan Union Hospital from January 2018 to January 2022 were retrospectively analyzed. Among the patients with pancreatic tuberculosis, 7 were male and 7 were female with the age of 39.7±16.0 years. The main clinical manifestations were abdominal distention, abdominal pain, loss of appetite, weight loss, abdominal mass, obstructive jaundice, skin pruritus, asymptomatic. Seven patients with pancreatic tuberculosis were complicated with tuberculosis in other organs, including 3 patients with pulmonary tuberculosis. Laboratory examination results showed 7 patients with anemia, 3 with elevated serum amylase, 2 with elevated bilirubin and 10 with positive anti-tuberculosis antibody, 12 positive for tuberculosis T-SPOT. Levels of CA19-9 in all patients were within normal range. Imaging examination results showed that 9 cases were solid mass, 4 cystic solid mass, 1 cystic mass, 4 with enlarged peripancreatic lymph node, and 2 with dilated bile duct. EUS showed that head of pancreas was the most common location of pancreatic tuberculosis. All the lesions were hyperechoic without vascular invasion, including 8 cases with homogeneous hyperecho, 6 cases with inhomogeneous hyperecho, 2 cases with hyperechoic calcification and 1 case of echoless colliquative necrosis area. The diameter of the mass was 3.9±1.6 cm, with 5 cases <3 cm and 9 cases ≥3 cm. Pathological biopsy showed 12 cases of caseous granuloma. Etiological examination results showed that 11 cases were positive for polymerase chain reaction for mycobacterium tuberculosis, 3 positive for acid-fast stain, 1 positive for culture. All the patients were treated with regular anti-tuberculosis drugs, and 3 patients with jaundice were treated with endoscopic retrograde cholangiopancreatography and biliary stent placement. All patients showed good prognosis during the follow-up period. For patients with pancreatic space-occupying lesions, the possibility of pancreatic tuberculosis should be considered. The current diagnostic method relies on tissue biopsy and aetiological examination. EUS-FNA is the preferred method for obtaining pancreatic tissue to avoid unnecessary surgery, and to provide timely and accurate diagnosis. Regular anti-tuberculosis treatment is the main treatment for pancreatic tuberculosis.
