The Tokyo Guidelines 2013 (TG13) for acute cholangitis and cholecystitis were globally disseminated and various clinical studies about the management of acute cholecystitis were reported by many researchers and clinicians from all over the world. The 1^st edition of the Tokyo Guidelines 2007 (TG07) was revised in 2013. According to that revision, the TG13 diagnostic criteria of acute cholecystitis provided better specificity and higher diagnostic accuracy. Thorough our literature searc

Ampullectomy for early ampullary cancer should not be considered an alternative operation to PD because of the high possibility of recurrence. PD should be preferably performed for adequate radical resection, even in early ampullary cancer, and ampullectomy should be reserved for those who have pTis or pT1 cancer sized 1.0 cm or less with high operative risk.

The favorable long-term oncologic results shown in this study confirm the oncologic safety of laparoscopic cholecystectomy, including laparoscopic lymphadenectomy in selected patients with GBC.

This study demonstrates that laparoscopic surgery can be an effective option for managing IHD stones and it also suggests the potential role of laparoscopic surgery for treating IHD stones in the era of laparoscopy.

Rapid decision-making is mandatory when bleeding stigmata such as pseudoaneurysm on CT and sentinel bleeding are noted. Prompt operation for early bleeding and angiographic embolization for late bleeding are recommended. In order to prevent hemorrhage after pancreatoduodenectomy, meticulously performed hemostasis and the avoidance of pancreatic anastomotic leaks are essential.

A 57-year-old man presented with a liver mass that had been detected on physical examination. The abdominal computed tomography scan revealed a 5-cm single nodular hepatoma located in segments 6 and 7. A total laparoscopic right posterior sectionectomy was performed for this lesion. The anatomical demarcation of the posterior section was possible with selective control of a Glissonian pedicle to that section. The patient was discharged on postoperative day 13 without complications. The postopera

The complexity classification outperformed the major/minor classification for predicting the surgical difficulty of liver resection.

The LFT values on initial admission and the changes in LFT values over time are reliable predictors of CBD stones in patients with AC.

A central bisectionectomy of the liver removes segments 4, 5, and 8, and this is a technically demanding operation because it requires two transection planes. Until now, the laparoscopic approach for this operative procedure has been rarely attempted. We report in this article on a totally laparoscopic central bisectionectomy that was performed in a 49-year-old male who had centrally located hepatocellular carcinoma (HCC), and this tumor was in contact with the middle hepatic vein. The operative

This survey and literature review revealed that laparoscopic surgery for GBC is performed in highly selected cases. However, the favorable outcomes in the published reports and the positive view of experienced surgeons for this operative procedure suggest a high likelihood that laparoscopic surgery will be more frequently performed for GBC in the future.

Uncontrolled severe hyperglycemia rather than preoperative DM negatively affects the survival outcomes following PDAC resection.
