Objective To compare the prognostic differences between simple and complex segmentectomies. Methods We conducted a retrospective cohort analysis of patients with solid pulmonary nodules (≤2 cm) who underwent segmentectomy. Recurrence-free survival (RFS) and local recurrence rates were evaluated. Results We included57 patients undergoing complex segmentectomy and 53 patients undergoing simple segmentectomy. Among patients who did not receive adjuvant therapy, those in the complex group had a significantly lower five-year RFS than those in the simple group (69.86% vs. 85.97%, P=0.04). Furthermore, the local recurrence rate was significantly higher in the complex group (18.75% vs. 4.65%, P=0.003) than in the simple group. Conclusion For solid pulmonary nodules (≤2 cm), complex segmentectomy is associated with inferior local control and worse RFS than simple segmentectomy.

Objective To investigate the features,prevention and treatment of complications of ultrasound-guided hepatic puncture biopsy.Methods One hundred and seventy-five cases underwent ultrasound-guided hepatic puncture biopsy were retrospectively analyzed.Results The incidence of complications was 16 cases (9.1%),including 5 cases with vasovagal episodes(2.9%),4 cases with ache which needed medicine treatment (2.2%),3 cases with hemorrhage in liver capsule(1.7%),3 cases with hypoglycemia(1.7%),1 case with serve hemorrhage in abdominal cavity(0.6%).Hemorrhage limited in liver capsule,vasovagal episodes,hypoglycemia and ache were relieved with corresponding treatments.One case with hemorrhage in abdominal cavity was handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.Conclusions Ultrasound-guided hepatic puncture biopsy has good value and low complication.The most severe complication is hemorrhage,which can be handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.
