Two cases of intestinal obstruction caused by tuberculosis—the role of frozen section diagnosis

A total of 155 consecutive patients underwent intraoperative FS procedure, and 110 of those cases had TPC available for review. TPC was diagnostic or contributory to FS diagnosis in 97 (88%) cases, and non-contributory in 13 cases, mainly due to low or inadequate cellularity. TPC provided useful information regarding tumour subtyping, but it was less sensitive in the diagnosis of mucinous neoplasms and was less specific in the assessment of bronchial resection margins. In granulomatous lesions with or without necrosis, TPC was diagnostic in 10 (91%) cases. In five cases (including four cases of tuberculosis), TPC was the only diagnostic tool since FS was not completed. In conclusion, TPC showed high sensitivity and specificity rates and was contributory to FS diagnosis of pulmonary lesions. TPC provides a fast, less-expensive method of diagnosis, utilises a minimal amount of tissue, and can save processing of fresh frozen tissues in certain situations such as tuberculous lesions.
