BACKGROUND: Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years. METHODS: A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis. RESULTS: This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]). CONCLUSION: Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

Regorafenib is a multikinase inhibitor that was approved by the US Food and Drug administration in 2017. Cancer stem cells (CSCs) are a small subset of cancer-initiating cells that are thought to contribute to therapeutic resistance. The forkhead box protein M1 (FOXM1) plays an important role in the regulation of the stemness of CSCs and mediates resistance to chemotherapy. However, the relationship between FOXM1 and regorafenib resistance in liver cancer cells remains unknown. We found that regorafenib-resistant HepG2 clones overexpressed FOXM1 and various markers of CSCs. Patients with hepatocellular carcinoma also exhibited an upregulation of FOXM1 and resistance to regorafenib, which were correlated with a poor survival rate. We identified a close relationship between FOXM1 expression and regorafenib resistance, which was correlated with the survival of patients with hepatocellular carcinoma. Thus, a strategy that antagonizes FOXM1-CD44 signaling would enhance the therapeutic efficacy of regorafenib in these patients.

BACKGROUND: We developed laparoscopic transfistulous bile duct exploration (LTBDE) for Mirizzi syndrome (MS) McSherry type II in September 2011. Then, single-incision LTBDE (SILTBDE) was adopted as a preferred technique since August 2013. This retrospective study aims to analyze the outcome of LTBDE in 7.7 years and to compare SILTBDE with four-incision LTBDE (4ILTBDE). METHODS: Seventeen consecutive patients underwent LTBDE for MS McSherry type II from September 2011 to May 2019. Transfistulous removal of the impacted stone(s), choledochoscopic bile duct exploration, and primary closure of the gallbladder remnant were performed without biliary drainage. RESULTS: The sex ratio is 12:5 (male: female) with an average age of 39.4 ± 10.3 (24-56) years. Ten patients (58.8%) had their diagnoses of MS established by preoperative imaging. According to the Csendes classification, three type II (17.6%), nine type III (52.9%), and five type IV (29.4%) were identified. The operative time was 264.8 ± 60.3 min (156-358 min). The stone clearance rate was 100%. The postoperative hospital stay was 4.7 ± 1.9 (2-10) days. No procedure was converted to an open operation. Two postoperative transient hyperamylasemia (11.8%) and one superficial wound infection (5.9%) occurred and all recovered well under conservative treatment (Clavien-Dindo grade I). During an average 2.2-year follow-up period, no biliary stricture or stone recurrence occurred. No significant difference exists between the SILTBDE and 4ILTBDE groups. Nevertheless, an insignificant trend of shorter postoperative hospital stay was observed in the former. A diagnosis of MS Csendes type IV implicates prolonged total and postoperative hospital stays (p < 0.01). CONCLUSIONS: LTBDE is safe and efficacious for MS McSherry type II. It provides a simple solution for various types of MS and avoids undesirable complications following bilioenteric anastomosis. SILTBDE is comparable to 4ILTBDE for selected patients. Patients with MS Csendes type IV need more time to recover after surgery.

This study aimed to describe our experience and discuss the results, controversies, and the use of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary complications after liver transplantation (LT). Between November 2009 and August 2020, 76 consecutive patients who underwent 77 LTs (44 deceased donor LTs and 33 living donor LTs [LDLT]) were enrolled retrospectively. Endoscopic therapy as initial approach and PTBD as rescue therapy were used for patients with biliary complications. There were 31 patients (31/76, 40.8%) with biliary complications, and two of them died (2/31, 6.5%). Clinical success rate of endoscopic therapy alone was 71.0% (22/31). The remaining nine patients received salvage PTBD and their clinical results were observed according to whether their intrahepatic bile ducts (IHBDs) was dilated (group A, n = 5) or not (group B, n = 4). In group A, the technical and long-term clinical success rates of PTBD were 100% and 20%, respectively. These five patients received PTBD ranging from 75 to 732 days after their LTs, and no procedure-related complications were encountered. In group B, the technical and long-term clinical success rates of PTBD were 50% and 25%, respectively. Three group B patients (75%) underwent PTBD within 30 days after LDLT and had lethal complications. One patient had graft laceration and survived after receiving timely re-transplantation. The other two patients died of sepsis due to PTBD-related bilioportal fistula or multiple liver abscesses. Our experience showed salvage PTBD played a limited role in biliary complications without dilated IHBDs within 1 month after LT.

Liver transplantation (LT) candidates often present with poor oral hygiene, which could potentially lead to systemic infections and sepsis owing to their cirrhotic state. In this study, we investigated the oral health status of LT candidates and propose guidance for the detection and treatment of encountered oral lesions among these patients. The decayed, missing, and filled teeth (DMFT) index was determined through oral examination. The presence of dental calculus was detected using panoramic radiography and defined by the radiopaque dental calculus (RDC). From January 2011 to August 2018, 56 LT candidates were enrolled with a median follow-up of 39 months. The overall mean numbers of decayed, missing, and filled teeth among these patients were 2.7 ± 2.8, 10.9 ± 8.3, and 5.4 ± 4.5, respectively. Eighteen patients (32.1%) had RDC. The 5-year survival rates of all 56 patients was 57.7%, while that of those who either received LT (23 patients) or not were 82.1% and 39.8%, respectively. A Cox regression model revealed better overall survival of patients after LT (adjusted hazard ratio [aHR] = 0.067, p = 0.001), worse survival among patients with RDC (aHR = 3.468, p = 0.010), at Child-Pugh stages B and C (aHR for stage B = 11.889, p = 0.028; aHR for stage C = 19.257, p = 0.013) compared to patients at Child-Pugh stage A, and those with a model for end-stage liver disease (MELD) score ≥25 (aHR = 13.721, p = 0.018). This study demonstrates that RDC was associated with worse prognosis in LT candidates. We therefore recommend that interprofessional collaboration should be a routine preoperative procedure for the evaluation of oral hygiene among LT candidates.

BACKGROUND: Effective prognostic biomarkers and powerful target-therapeutic drugs are needed for improving the treatment of Hepatocellular carcinoma (HCC). OBJECTIVE: This study aimed to evaluate the expression of FOXM1 and Aurora-A and their prognostic value in HCC. METHODS: We determined the differentially expressed genes signature in HCC using the Gene Set Enrichment Analysis (GSEA), and then evaluated the expression of FOXM1 and Aurora-A in TCGA and KMUH cohort. Associations between co-expression of FOXM1 and Aurora-A and clinical variables were calculated. Overall survival (OS) and recurrence-free survival (RFS) were estimated with different FOXM1 and Aurora-A expression status. RESULTS: FOXM1-related gene sets were mostly associated with cell cycle regulation in HCC tissues. We found a positive correlation between the expression of FOXM1 and Aurora-A. Overexpression of FOXM1 and Aurora-A was associated with larger tumor size, advanced stage, higher grade, and double-positive for HBV and HCV. The coordinated overexpression of FOXM1 and Aurora-A was the most significant independent prognostic factor for OS and RFS. Furthermore, the concomitant high expression of FOXM1 and Aurora-A predicted the worst OS of sorafenib-treated patients with HCC. CONCLUSIONS: The co-expression of FOXM1 and Aurora-A could be a reliable biomarker to predict the sorafenib response and prognosis of HCC patients.

AIM: This paper aims to describe an intracorporeal tourniquet method for laparoscopic Pringle maneuver (PM). METHODS: One shortened Foley tube with side-hole on the tip was put into the abdomen. Then, the tail was pulled out through the side-hole to make a loop to encircle porta hepatis for inflow control. RESULT: It is easy to keep the tension by a metallic clip, and when released, the clip can be removed and the loop loosened. CONCLUSION: Therefore, PM could be performed inside the abdomen without special instrument nor extra trocar port. The intracorporeal Pringle maneuver with Huang's loop could be routinely used during laparoscopic liver resection even for a laparoscopic beginner because it is so easily learnt, safe, and effective.

BACKGROUND: Multiport laparoscopic cholecystectomy is the standard surgical procedure for symptomatic gallbladder diseases. The latest evolution is single incision laparoscopic cholecystectomy (SILC). Single-site robotic cholecystectomy (SSRC) overcomes several limitations of manual SILC. The aim of this study is to present our initial experiences in SSRC and to compare its clinical outcomes with those of SILC. METHODS: This study retrospectively reviewed data for patients who received SSRC or SILC from February 2014 to September 2015. The following variables were analyzed: age, sex, body mass index, indications, pain scale, length of stay, and complications. The data were analyzed with Student t test or by Fisher exact test. RESULTS: The analysis included 51 SSRC (33 women, 18 men) and 63 SILC patients (40 women, 23 men). Patients in both groups had similar demographic features and indications for surgery. The SSRC group required no conversions to conventional laparoscopy and no additional trocars, whereas the SILC group had two (3.17%) cases. Length of stay did not significantly differ between the SSRC and SILC groups (4.29 ± 0.72 vs. 4.13 ± 0.93 days, respectively; p = 0.823). However, the SSRC group had shorter operative time (71.30 ± 48.88 vs. 74.70 ± 30.16 minutes; p = 0.772), less perioperative bile spillage (9.81% vs. 19.05%; p = 0.189), and less postoperative bile leakage (0% vs. 3.17%; p = 0.501). However, the parameters mentioned above were not statistically significant, whereas pain scale scores were significantly lower in the SSRC group (2.11 ± 0.76 vs. 3.98 ± 0.84; p < 0.01). CONCLUSIONS: Both SSRC and SILC are safe and feasible procedures for performing single incision cholecystectomy. SSRC, however, has the advantage of significantly decreased postoperative pain.

If portal vein stenosis (PVS) occurs within 1 month after liver transplantation (LT), especially within 1 week, it can be catastrophic and result in rapid loss of the grafts and mortality. Although surgical treatments have been considered standard treatment for PVS, patients are usually unable to receive operations or re-transplantations, because of their critical conditions and a shortage of grafts. Recently, primary percutaneous transhepatic portal vein stents (PTPS) were suggested as alternative and less-invasive treatments of PVS. However, because lethal complications may follow these primary stent placements for patients in early stages after LT, primary PTPS placements for patients suffering PVS 1 month after LT has been suggested. From November 2009 to July 2015, 38 consecutive adult patients underwent LT at our institution. Among them, six recipients suffered PVS within 1 month after LT. Technical success was achieved in all six patients. Clinical success was obtained in two of the four patients suffering PVS within 1 week after LT, and in the other two patients suffering PVS>1 week after LT. All surviving patients and their grafts were in good condition, and their stents remained patent. Our experience showed that primary PTPS placements can be used to effectively treat patients with PVS encountered within 1 month, and even within 1 week, after LT with acceptable short-term results. However, possible fatal complications should be kept in mind. Long-term results of these procedures need further follow-up.
