【 要旨 】 総胆管結石症の治療には内視鏡による総胆管結石摘出が多く行われている.胆囊結石が合併する場合は術前もしくは術後に胆囊摘出が追加されることが多い(二期的治療)が,一期的に総胆管結石除去術,胆囊摘出術を行う施設もある(一期手術).十二指腸乳頭が温存できる一期手術は,二期的治療に比べ結石除去率,死亡率,合併症率で差がないものの,入院期間が短縮,医療費が抑制されるという利点がある.しかしながら一期手術は特殊な機械と外科医の経験が必要なため,広く行われている治療とは言い難い.外科治療には,胆囊摘出・総胆管結石除去術を開腹で行う場合と腹腔鏡下に行う場合があり,アプローチ法により経胆囊管法と胆管切開法がある.

[ Summary ] The most common interventional options for patients with concomitant common bile duct stones (CBDS) and gallstones include : 1) two‒stage approach combining laparoscopic choledochotomy with preoperative or postoperative endoscopic retrograde cholangiography, 2) single‒stage laparoscopic procedure with laparoscopic or laparotomic stone extraction. There is no significant difference in the mortality, morbidity, retained stones, and failure rates between the single‒stage laparoscopic procedure and two‒stage endoscopic approaches. Although both techniques are effective in managing choledocholithiasis, the suitable therapy depends on the conditions such as number and size of stones, the surgeon's experience, and patient's satisfaction. Laparoscopic common bile duct exploration is an ideal surgical management to preserve papillary function by applying small abdominal incision. Furthermore, this presents significantly lower cost to patients and the health care system. However, it remains challenging because of the technical difficulties. We herein review the different techniques of treating common bile duct stones with the special focus on various surgical modalities.
