◆要旨:【目的】当院における胃切除既往症例に対する腹腔鏡下胆囊摘出術(laparoscopic cholecystectomy:以下,LC)の手術成績を検討し,胃切除既往症例に対するLCが許容される術式か検討する.【対象と方法】2016年4月から2024年3月の8年間に当院で施行されたLC 2,228例のうち,胃切除既往症例45例を対象とし,背景因子と手術成績を検討した.【結果】胃切除既往症例の原疾患は胆囊結石症22例,急性胆囊炎22例,胆囊腫瘍1例で,手術時間中央値は139分,術中出血量中央値は40mL,開腹移行は8例(17.8%),Clavien-Dindo分類GradeⅡ以上の術後合併症は6例(13.3%)であった.【結語】胃切除既往症例に対するLCは胃切除既往のない症例と比較し,開腹移行率は高いものの,許容される術式であると考えられた.
[Purpose]We aimed to investigate the outcome of laparoscopic cholecystectomy(LC) in patients with a history of gastrectomy.[Patients and Methods]A total of 45 patients with a history of gastrectomy undergoing LC from April 2016 to March 2024 in our hospital were enrolled in this study. Background and surgical outcome of these patients were investigated.[Results]LC was indicated for gallbladder stone in 22 patients, acute cholecystitis in 22 patients, and gallbladder tumor in 1 patient. Median operation time was 139 min, and median intraoperative blood loss was 40mL. Eight patients(17.8%) required conversion from LC to open cholecystectomy. Postoperative complications greater than gradeⅡof Clavien-Dindo classification developed in 6 patients(13.3%).[Conclusion]LC in patients with a history of gastrectomy seems to be an acceptable procedure despite a higher conversion rate to open cholecystectomy compared to patients without any history of gastrectomy.
