First described in 1994, it has been slow to gain in popularity. Recently, however, we have seen an increase in the number of centers performing this operation, including our own institution, as well as an increase in the quantity of published data. The purpose of this review is to describe the current status of LPD as described in the literature. We performed a literature search in the Pub Med database using Me SH terms ＂laparoscopy＂ and ＂pancreaticoduodenectomy＂. We then identified articles in the English language with over 20 patients that focused on LPD only. Review articles were excluded and only one article per institution was used for descriptive analysis in order to avoid overlap. There were a total of eight articles meeting review criteria, consisting of 492 patients. On descriptive analysis we found that percent of LPD due to high-grade malignancy averaged 47% over all articles. Average operative time was 452 minutes, blood loss 369 cc＇s, pancreatic leak rate 15%, delayed gastric emptying 8.6%, length of hospital stay 9.4 days, and short term mortality 2.3%. Comparison studies between open pancreaticoduodenectomy（OPD） and LPD suggested decreased blood loss, longer operative time, similar post-operative complication rate, decreased pain, and shorter hospital length of stay for LPD. There was also increased number of lymph nodes harvested and similar margin free resections with LPD in the majority of studies. LPD is a safe surgery, providing many of the advantages typically associated with laparoscopic procedures. We expect this operation to continue to gain in popularity as well as be offered in increasingly more complex cases. In future studies, it will be beneficial to look further at the oncologic outcome data of LPD including survival.展开更多

Identification and development of more efficacious therapies is urgently needed. Immunotherapy offered encouraging results in preclinical models during the last decades, and several clinical trials have explored its therapeutic application in PDAC. The aim of this review is to summarize the results of clinical trials conducted to evaluate the future perspective of immunotherapy in the treatment of PDAC.展开更多
