The Modified Inflation-Deflation Method (MIDM) is widely used in China in pulmonary segmentectomies. We optimized the procedure, which was named as Blood Flow Blocking Method (BFBM), also known as "No-Waiting Segmentectomy". This method has produced commendable clinical outcomes in segmentectomies. The aim of this research is to confirm whether the intersegmental planes formed by MIDM and BFBM techniques during segmentectomies have high degree of concordance.
We utilized the Open Sequential Test design in our study. Using both MIDM and BFBM techniques, intersegmental planes were created in the same patient, one after the other. The degree of alignment between the planes formed by the two techniques was assessed by two experienced chief surgeons. Based on the results obtained in each case, a test line was plotted until it intersected the effective or ineffective line.
In every case studied, the intersegmental planes created by the MIDM and BFBM displayed high congruity. The test line crossed the effective line during the 12th case. When comparing the time taken to form the intersegmental plane using either MIDM or BFBM technique, no significant difference was observed. However, the application of the BFBM technique resulted in an average time savings of 13.8 min.
In segmentectomies, the intersegmental planes formed by MIDM and BFBM techniques exhibit high concordance. However, given that BFBM affords a time-saving advantage, we propose that BFBM could potentially replace MIDM in performing lung segmentectomies.
改良膨胀-萎陷法（MIDM）在中国肺段切除术中被广泛应用。我们对该手术方法进行了优化，将其命名为血流阻断法（BFBM），也称为“无需等待的肺段切除术”。该方法在肺段切除术中取得了值得称赞的临床效果。本研究的目的是确认在肺段切除术中，MIDM和BFBM技术所形成的肺段间平面是否具有高度一致性。
我们在研究中采用了开放序贯试验设计。在同一患者身上先后使用MIDM和BFBM技术创建肺段间平面。由两名经验丰富的主任医师评估两种技术所形成平面的对齐程度。根据每个病例的结果绘制一条测试线，直到它与有效线或无效线相交。
在每例研究病例中，MIDM和BFBM所创建的肺段间平面显示出高度一致性。测试线在第12例病例时穿过了有效线。当比较使用MIDM或BFBM技术形成肺段间平面所需的时间时，未观察到显著差异。然而，应用BFBM技术平均节省了13.8分钟。
在肺段切除术中，MIDM和BFBM技术所形成的肺段间平面具有高度一致性。然而，鉴于BFBM具有节省时间的优势，我们建议在进行肺段切除术时，BFBM有可能取代MIDM。
