Background null The concept of Minimally invasive anatomic liver resection (MIALR) is gaining popularity. However, specific technical skills need to be acquired to safely perform MIALR. The "Expert Consensus Meeting: Precision Anatomy for Minimally Invasive HBP Surgery (PAM-HBP Surgery Consensus)" was developed as a special program during the 32nd meeting of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS). null Methods null Thirty-four international experts gathered online for...

Major hepatectomy in patients with insufficient future liver remnant (FLR) volume and impaired liver functional reserve has considerable risks for posthepatectomy liver failure (PHLF). The patient was a male in his 70 with an intrahepatic cholangiocarcinoma (ICC) in left hemiliver, involving the middle hepatic vein (MHV). Although FLR volume after left hemihepatectomy was estimated to be 64.4% of the total liver volume, an indocyanine green retention rate at 15 min (ICG-R15) value was 24.2%, thu...

Background null Despite the major advances in analgesic techniques, pain relief in coughing after abdominal surgery remains challenging. Cough-related pain causes postoperative respiratory complications by impairing sputum clearance; nevertheless, an effective technique to abolish it is not yet available. We devised the bilateral flank compression (BFC) maneuver, in which the flanks are compressed medially using both hands. We conducted a prospective, single-center, single arm, nonrandomized, op...

Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer deaths in Japan, and it has gradually decreased in the last quarter century. The reason for the decrease in HCC patients is the decrease of patients with hepatitis C virus due to avoiding unnecessary blood transfusions and development of direct-acting antiviral agents (DAAs), which have been available since 2014, along with interferon and oral antiviral agents in Japan. On the other hand, the numbers of HCC patients with non-alc...

PURPOSE Resection of liver cancer involving the paracaval portion (PC) of the caudate lobe is challenging because the PC is located deepest in the liver. This study aimed to elucidate the utility of two parenchymal-sparing approaches of limited resection and central hepatectomy for resecting tumors located in the PC. METHODS In 2018 and 2020, 12 out of 143 patients underwent hepatectomy for tumors located in the PC of the liver. In six patients, limited resection (LR) of the PC after full mobili...

BACKGROUND Excision of the mesopancreas with lymphadenectomy is an important component of pancreatoduodenectomy. However, the optimal extent of lymphadenectomy remains unclear. Furthermore, accurate description of the mesopancreatic lymphatic pathways is difficult, probably because of the complex anatomy. Intestinal derotation simplifies the anatomy and facilitates both examination of lymphatic flow and the surgical procedure. The aim of this study was to evaluate lymphatic flow in the mesopancr...

Pancreatic cancer is known to have the poorest prognosis among digestive cancers. With the development of new chemotherapeutic agents and introduction of multidisciplinary therapy, however, the treatment outcomes for pancreatic cancer have dramatically improved over the past two decades. The keys to successful treatment will be accurate assessment of resectability [resectable (R), borderline resectable (BR) or unresectable (UR)] at the time of diagnosis and prompt adoption of an appropriate mult...
