Laparoscopic pancreaticoduodenectomy in patients with a history of right hemicolectomy : A report of three cases.

Laparoscopic pancreaticoduodenectomy (LPD) has been widely adopted in institutions with sufficiently skilled practitioners. This technique requires attentive dissection around the superior mesenteric vein (SMV) and artery. Dissection around the SMV and Henle's trunk is one of the key aspects of right hemicolectomy (RHC) ; adhesions and fibrosis around these vessels may impede LPD in patients with a history of RHC. We encountered three cases of periampullary tumors in patients with a history of RHC who were successfully treated with LPD. Cases 1, 2, and 3 were of 60-, 73-, and 74-year-old men with periampullary tumors. The operative durations in cases 1, 2, and 3 were 316, 267, and 265 min, respectively. The estimated blood loss volumes in cases 1, 2, and 3 were 20, 50, and 720 mL, respectively. The postoperative hospital stay durations in cases 1, 2, and 3 were of 13, 35, and 15 days, respectively. In conclusion, LPD following RHC may be safely completed with laparoscopy. J. Med. Invest. 70 : 285-289, February, 2023.
