BACKGROUND: In patients with Bismuth type I and II hilar cholangiocarcinoma (HCCA), bile duct resection alone has been the conventional approach. However, many authors have reported that concomitant liver resection improved surgical outcomes. METHODS: Between January 2000 and January 2012, 52 patients underwent surgical resection for a Bismuth type I and II HCCA (type I: n = 22; type II: n = 30). Patients were classified into two groups: concomitant liver resection (n = 26) and bile duct resecti

Cancer cells can exhibit resistance to different anticancer drugs by acquiring enhanced anti-apoptotic potential, improved DNA injury resistance, diminished enzymatic inactivation, and enhanced permeability, allowing for cell survival. However, the genetic mechanisms for these effects are unknown. Therefore, in this study, we obtained drug-sensitive HT-29 cells (commercially) and drug-resistant cancer cells (derived from biochemically and histologically confirmed colon cancer patients) and perfo

The findings revealed by the current study suggest that the role of bile duct resection might be limited to improved staging, and offers no advantage in long-term survival. However, in view of the foregoing and given the minimal increase in morbidity associated with BDR, it should be actively considered as a treatment option for patients who present with findings suspicious for invasion around hepatoduodenal ligament.

Hepatic actinomycosis and IgG4-related pseudotumors of the liver are both difficult to diagnose. As in our patient, combined diseases are more difficult to diagnose and to determine the optimal treatment. Since immunosuppression therapy of autoimmune diseases can cause and aggravate infection, management must be approached carefully. We can learn that various possibilities must be considered before diagnosing and treating a hepatic mass.

Drug resistance causes therapeutic failure in refractory cancer. Cancer drug resistance stems from various factors, such as patient heterogeneity and genetic alterations in somatic cancer cells, including those from identical tissues. Generally, resistance is intrinsic for cancers; however, cancer resistance becomes common owing to an increased drug treatment. Unfortunately, overcoming this issue is not yet possible. The present study aimed to evaluate a clinical approach using candidate compoun

BACKGROUND: Minimal invasive surgery in hepatobiliary and pancreatic (HBP) surgery has been accepted worldwide in recent years. However, applications of single-site laparoscopic surgery in complex HBP surgery have been limited due to difficulty in manoeuvring instruments and the limited range of motion resulting from clashing instruments. METHODS: To overcome the limitations, we have used the Da Vinci single-site surgical platform with one additional port in a Da Vinci Xi system to perform donor

Concurrent intra-arterial chemotherapy and radiotherapy (iA-CCRT) can increase the response rate in hepatocellular carcinoma (HCC), but may cause a higher toxicity. We conducted this Phase I study to investigate the dose-limiting toxicity of iA-CCRT for HCC. In total, 52.5 Gy in 25 fractions was prescribed as planning target volume (PTV) 1 at dose level 1. The dose escalation was 0.2 Gy per fraction and up to 2.5 Gy, with 62.5 Gy at level 3. Concurrent intra-arterial 5-fluorouracil was administe

BACKGROUND: Laparoscopic cholecystectomy (LC) causes moderate pain. Various operative analgesic techniques and pharmacologic treatments can reduce postoperative pain. This single-center, single-surgeon randomized controlled study aimed to assess the efficacy of combined operative analgesic techniques and pharmacologic analgesia in decreasing pain in patients undergoing LC. MATERIALS AND METHODS: Fifty-nine patients scheduled for LC were assigned into two groups. In the pharmacologic analgesia (P

Abstract Background Some studies have analyzed the frequency of HCV RNA testing and actual treatment among anti-HCV positive patients in Korea, which has a low prevalence of HCV infection. This study aimed to analyze the diagnosis process, treatment results, and prognosis according to care cascade in patients who are anti-HCV positive. Methods Three thousand two hundred fifty-three anti-HCV positive patients presented to a tertiary hospital between January 2005 and December 2020. The number of p
