Incidence and risk factors of postoperative complications in patients with tuberculosis-destroyed lung

BMC Pulm Med. 2021 Aug 21;21(1):273. doi: 10.1186/s12890-021-01641-0.

ABSTRACT

BACKGROUND: The purpose of this study was to determine risk factors of postoperative complications in tuberculosis-destroyed lung (TDL) patients.

METHODS: We retrospectively analyzed the data from all consecutive TDL patients undergoing surgical treatment at the Beijing Chest Hospital from January 2001 to September 2019.

RESULTS: Of 113 TDL cases experiencing surgery, 33 (29.2%) experienced postoperative complications. The patients with low BMI were more likely to have postoperative complications compared to those with normal BMI, whereas a significant lower rate of postoperative complications was noted in patients with BMI ≥ 25 kg/m2. In addition, significant increased risk was observed in patients with smoking history. We found that the patients with underlying infection, including aspergillus and nontuberculous mycobacteria (NTM), had significantly higher odds of having postoperative complications compared with those without underlying infection. The anaemia was another important independent factor associated with postoperative complication. Patients with blood transfusion above 1000 mL had a strongly increased frequency of postoperative complications than patients with blood transfusion below 1000 mL.

CONCLUSION: In conclusion, our data demonstrate that approximate one third of TDL patients experience postoperative complications in our cohort. Patients with low BMI, anaemia, tobacco smoking, and coinfected aspergillus or NTM are at markedly higher risk to experience postoperative complications after pneumonectomy.
