Abstract 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 ( TG 07) was revised in 2013. According to that revision, the TG 13 diagnostic criteria of acute cholecystitis provided better specificity and higher diagnostic accuracy. Thorough our literature sea

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.

BACKGROUND/AIMS: Hemorrhage after pancreatoduodenectomy is a severe, life-threatening complication. This study was conducted to determine the guidelines appropriate for the prevention and management of hemorrhagic complications. METHODOLOGY: We reviewed the medical records of 456 patients who had undergone pancreatoduodenectomy at our hospital between 1991 and 2000. RESULTS: Significant postoperative bleeding occurred in 21 patients (4.6%). Early bleeding (within the 5th postoperative day) cause

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.

BACKGROUND: Prior studies have examined the use of liver function tests (LFT) for predicting the presence of common bile duct (CBD) stones in chronic cholecystitis (CC) patients. It is currently unclear whether LFT are also useful for predicting CBD stones in patients with acute cholecystitis (AC). METHODS: Of 1059 patients who visited an emergency room with gallbladder-related symptoms between March 2004 and December 2009, 854 patients were analyzed, and were divided into three groups (556 AC p

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
