title: Disadvantage of operation cost in laparoscopy-assisted distal gastrectomy under the national health insurance system in Japan.
abstract: BACKGROUND
  The utility and problems including the socioeconomic aspect of laparoscopy-assisted distal gastrectomy for gastric cancer have not been fully evaluated.
  
  
  METHODS
  We compared open distal gastrectomy and laparoscopy-assisted distal gastrectomy for the clinical benefit, quality of life, and problems of operation cost by the reference documents in which the difference between open distal gastrectomy and laparoscopy-assisted distal gastrectomy was examined in detail. The reference documents retrieved by the key words 'gastric, cancer, laparoscopic, surgery' were 22 in PubMed with the following limits activated: Humans, Clinical Trial, Meta-Analysis, Randomized Controlled Trial, Review, English, Core clinical journals, published in the last 10 years.
  
  
  RESULTS
  The operation time of laparoscopy-assisted distal gastrectomy is longer than that of open distal gastrectomy. However, if skilled, the blood loss of laparoscopy-assisted distal gastrectomy is less, the hospitalization days and the duration of fasting after laparoscopy-assisted distal gastrectomy are shorter than those after open distal gastrectomy. The number of excised lymph nodes and the incidence of postoperative complications were similar between laparoscopy-assisted distal gastrectomy and open distal gastrectomy. On the other hand, in the national health insurance system, the operation fee of open distal gastrectomy was USD 6,637 as compared to USD 7,586 for laparoscopy-assisted distal gastrectomy. In spite of the USD 949 difference in the operation fee, the use of disposable instruments for laparoscopy-assisted distal gastrectomy results in a deficit of USD 1,500 over open distal gastrectomy.
  
  
  CONCLUSIONS
  In spite of the medical superiority of laparoscopy-assisted distal gastrectomy over open distal gastrectomy (if a skilled surgeon operates) as less invasive surgery, laparoscopy-assisted distal gastrectomy is associated with less financial benefit to the hospital as compared to open distal gastrectomy in the current Japanese health insurance system.
