◆要旨:【背景】当科では急性胆囊炎症例に対して,卒後3〜6年目のレジデントが腹腔鏡下胆囊摘出術(LC)の執刀を行い,高難度例では術者交代を考慮し,安全性を担保する.【目的・方法】当科で2013〜2015年にLCを施行された急性胆囊炎149例を対象に,レジデント完遂例と,術者交代例の2群で患者背景を比較し,難易度規定因子を検討する.【結果】完遂例は94例,交代例は55例であった.年齢(完遂例:交代例=61.1:71.9歳,p<0.01),CRP値(5.8:12.5mg/dl,p<0.01),胆囊短径(36.3:39.7mm,p<0.01),ショックバイタル患者数(0/94:6/55人,p<0.01)が交代例で高値であった.多変量解析を行うと,年齢,CRP値,ショックバイタルが術者交代のリスクであった(p<0.01).【結語】急性胆囊炎に対するLCの難易度を術前スクリーニングできる可能性がある.
[Introduction] In our department, 3-6 year residents perform laparoscopic cholecystectomy for acute cholecystitis. But difficult cases need changes of operator (senior residents to specialists). [Purpose] To clarify the difficulty of laparoscopic cholecystectomy for acute cholecystitis. [Methods] We analyzed 149 cases of acute cholecystitis in our department. We compared cases that needed changes of operator with that didn't need changes, and evaluated factors concerned with difficulty. [Result] Fifty-five cases needed changes of operator. These cases had superiorities in age (61.1 : 71.9 years old, p<0.01), CRP values (5.8 : 12.5mg/dl, p<0.01), minor axis of gallbladder (36.3 : 39.7mm, p<0.01), and the numbers of shock (0/94 : 6/55, p<0.01) in univariate analysis. Age, CRP values, and the numbers of shock are independent risk factors for changes of operator in multivariable analysis (p<0.01). [Conclusion] We could possibly evaluate difficulty on laparoscopic cholecystectomy for acute cholecystitis.
