Efficacy analysis of hybrid operating room-based laparoscopic cholecystectomy combined with intraoperative endoscopic retrograde cholangiopancreatography in the treatment of cholelithiasis combined with choledocholithiasis - A case-control study.

Objective: The objective is to compare the therapeutic effects of laparoscopic cholecystectomy (LC) combined with intraoperative endoscopic retrograde cholangiopancreatography (ERCP) in hybrid operating room and ERCP + LC under traditional conditions in the treatment of cholelithiasis and choledocholithiasis. Materials and Methods: Data of 82 patients with cholelithiasis complicated with choledocholithiasis treated by our centre from November 2018 to March 2021 were retrospectively analysed. Amongst them, 40 patients treated with LC combined with intraoperative ERCP in a hybrid operating room were placed into Group A, and 42 patients treated with ERCP first followed by LC under traditional conditions were placed into Group B. The differences in operative time, intraoperative blood loss, surgical success rate, stone clearance rate, pain score, exhaust time, ambulation time, post-operative complications, length of hospital stay, hospitalisation cost and other indicators between the two groups were compared. Results: There were no significant differences in operative time, intraoperative blood loss, surgical success rate and stone clearance rate between the two groups (P > 0.05), while there were significant differences in post-operative pain score, exhaust time, ambulation time, length of hospital stay, hospitalisation cost and complications (P < 0.05). Conclusion: LC combined with intraoperative ERCP in hybrid operating room for the treatment of cholelithiasis combined with choledocholithiasis has a better therapeutic effect than traditional ERCP followed by LC, which is worthy of further popularization. Notably, the reasonable selection should be made based on patients' own conditions and hospital facilities.

The role of vesicular overexpressed in cancer pro-survival protein 1 in hepatocellular carcinoma proliferation.

BACKGROUND: Recently, hepatocellular carcinoma (HCC) has been ranked as the second leading cause of cancer-associated death. However, the underlying molecular mechanisms of HCC progression remain unclear. Vesicular overexpressed in cancer pro-survival protein 1 (VOPP1) could be upregulated in a quantity of human cancers, including squamous cell carcinoma (SCC), gastric cancer, and glioblastoma. However, the precise functional mechanism of VOPP1 in HCC remains poorly understood. The present study aimed to investigate the role of VOPP1 in HCC proliferation. METHODS: Immunohistochemistry (IHC), Western blot and Reverse-transcription polymerase chain reaction (RT-PCR) were used to analyze the protein and mRNA expressions of VOPP1, mitogen-activated protein kinase (MAPK) 14, ribosomal protein S6 kinase ß1 (RPS6KB1), cylindromatosis (CYLD) and Twist family bHLH transcription factor 1 (TWIST1). The cell proliferation and apoptosis were tested using Celigo cell imaging analyzer and annexin V-APC apoptosis detection kit respectively. Colony formation and tumor xenograft assays were performed to understand their roles in tumorigenicity. RESULTS: The expression of VOPP1 in HCC samples was higher than that in adjacent noncancerous tissues by immunohistochemistry. In addition, the down-regulation of VOPP1 using shRNA inhibited cell proliferation and tumour growth, and induced cell apoptosis in vitro and in vivo. Furthermore, VOPP1 silencing increased the expression of MAPK14 and RPS6KB1, indicating that the MAPK and mTOR signalling pathways might be involved in VOPP1-mediated cancer cell proliferation. CONCLUSION: The present data indicate that VOPP1 may play an important role in the progression of HCC by targeting the MAPK and mTOR signalling pathways, and that VOPP1 may potentially be a candidate as a novel molecular target for HCC therapy.

A clinical study of choledochoscopic holmium laser lithotripsy for multiple intrahepatic calculi within ERAS programs.

OBJECTIVES: Multiple intrahepatic calculi, especially calculi in both sides of the liver, cannot be completely resolved by traditional surgery. In addition, morbidity after liver resection remains high. ERAS programs have been suggested that could relieve surgical stress and accelerate postoperative recovery. This study aimed to evaluate the safety and efficacy of choledocholithotomy combined with holmium laser lithotripsy in the treatment of multiple intrahepatic calculi within ERAS programs. METHODS: In all, 109 patients with multiple intrahepatic calculi were enrolled between January 2012 and September 2016, 42 of whom received choledocholithotomy combined with holmium laser lithotripsy. The remaining 67 patients underwent choledocholithotomy combined with choledochoscopic mechanical lithotripsy. Perioperative outcomes were compared and analyzed. RESULTS: Patient characteristics and preoperative details were similar between the groups (P > 0.05). The implementation of holmium laser lithotripsy could reduce the calculi residual rate (7.1% vs. 22.4%, P = 0.037), and even the liver resection rate (16.7% vs. 35.8%, P = 0.031). Additionally, holmium laser lithotripsy did not result in a higher morbidity (11.9% vs. 16.4%, P = 0.517), readmission rate (0% vs. 6%, P = 0.158), hospital stay (P = 0.189), hospital cost (P = 0.998), transfusion rate (P = 0.576), or operative time (P = 0.638). CONCLUSIONS: Holmium laser lithotripsy is feasible and efficient for treating multiple intrahepatic calculi within ERAS programs, which could reduce the liver resection rate and render refractory hepatic calculi easy to eliminate. In addition, holmium laser lithotripsy could be well coupled to the ERAS program to relieve surgical stress and accelerate postoperative recovery. Lasers Surg.

Laparoscopic hepatectomy combined with endoscopic papillary balloon dilation for complex bile duct stones.

BACKGROUND: We evaluated the feasibility and efficacy of laparoscopic hepatectomy (LH) combined with endoscopic papillary balloon dilation (EPBD) for removing intra- and extrahepatic bile duct stones. METHODS: A total of 26 patients with intra- and extrahepatic bile duct stones underwent LH and EPBD. Selective hemi-hepatic vascular occlusion was used to complete the LH. EPBD was performed under the guidance of a guidewire, and stones were removed with a stone basket or balloon. RESULTS: A one-stage LH with EPBD lithotomy was successfully performed in 26 cases. No residual bile duct stones, intestinal or bile duct perforations were found. In addition, no severe post-operative bleeding, severe pancreatitis or mortality occurred. Post-operative hyperamylasemia was observed in five cases and bile leakage in one case. Post-operative hospital stays lasted 7-11 days. CONCLUSION: LH combined with EPBD applied to intra- and extrahepatic bile duct stones was feasible, effective and safe, resulting in rapid recovery and few post-operative complications.

Enhanced Recovery after Surgery Programs for Liver Resection: a Meta-analysis.

BACKGROUND AND AIMS: Due to the limited number of high-quality randomized controlled trials on enhanced recovery after surgery for hepatectomy, previous reviews have not been sufficiently comprehensive. Our objectives were to evaluate and compare the safety and efficacy of enhanced recovery after surgery programs and traditional care in patients undergoing open or laparoscopic surgery and to assess the optimized items for hepatectomy. METHODS: We searched the PubMed, Embase, and the Cochrane Library databases for all the relevant studies regardless of study design. We assessed the methodological quality of the included studies and excluded studies of poor quality. We performed a meta-analysis using RevMan 5.3 software. RESULTS: In total, 19 original studies with 2575 patients, including four randomized controlled trials and 15 non-randomized controlled trials, were analyzed. The meta-analysis demonstrated that enhanced recovery after surgery programs could reduce morbidity, hospital stays and cost, blood loss, and time to bowel function recovery for both open and laparoscopic surgery without increasing mortality, readmission rate, or transfusion rate. Twelve items were essential for liver surgery. CONCLUSIONS: Enhanced recovery after surgery programs for hepatectomy are feasible and efficient. Further studies should optimize perioperative outcomes for liver surgery.

Choledochoscopic Holmium Laser Lithotripsy for Difficult Bile Duct Stones.

OBJECTIVE: The aim of this study was to evaluate the feasibility and efficacy of choledochoscopic holmium laser lithotripsy as a means of removing resistant extrahepatic and intrahepatic bile duct stones. METHODS: Clinical data on 28 patients who had undergone choledochoscopic holmium laser lithotripsy were analyzed. RESULTS: Complete stone clearance was obtained in 24 patients; small numbers of residual stones in the left or right hepatic duct were found in 4 patients. No severe complications such as hemobilia and bile duct injuries occurred. CONCLUSION: Choledochoscopic holmium laser lithotripsy is a simple, safe, and effective treatment method for patients with resistant bile duct stones.

One-Step LC and ERCP Treatment of 40 Cases with Cholelithiasis Complicated with Common Bile Duct Stones.

BACKGROUND/AIMS: To discuss the clinical significance of combined application of laparoscopic cholecystectomy (LC) and endoscopic retrograde cholangiopancreatography (ERCP) for one-stage treatment of cholelithiasis complicated with common bile duct stones. METHODOLOGY: To retrospectively analyze 40 cases with cholelithiasis complicated with common bile duct stones treated with LC plus intraoperative ERCP between May 2005 and September 2012 and to evaluate the clinical efficacy in the treatment of cholelithiasis complicated with common bile duct stones. RESULTS: Among 40 cases, 36 successfully underwent LC plus intraoperative ERCP and 4 were transferred to open surgery. Eighteen patients with preoperative abnormal liver function showed declined indexes post-operatively. Compared with LC, more patients had abdominal distention and vomiting. Seven patients presented with transient increase in the levels of serum amylase with no incidence of acute pancreatitis. One had hematochezia and recovered after conservative treatment with no incidence of bile leakage and perforation and other severe complications. CONCLUSIONS: LC combined with intraoperative ERCP is safe and efficacious in the primary treatment of cholelithiasis complicated with common bile duct stones to avoid open surgery and double surgeries.

Lesion human leukocyte antigen-F expression is associated with a poor prognosis in patients with hepatocellular carcinoma.

Human leukocyte antigen (HLA)-F, a non-classical HLA-class I molecule, has attracted attention as an important immunosuppressive molecule in recent years, although the clinical relevance of HLA-F expression in cancer patients remains unclear. In the present study, HLA-F expression in 90 primary hepatocellular carcinoma (HCC) lesions and 55 corresponding adjacent normal liver tissues was analyzed by immunohistochemistry, and the associations between HLA-F expression and clinicopathological parameters and patient survival times were analyzed. Positive HLA-F expression was observed in 47.8% (43/90) of the HCC lesions and in 10.9% (6/55) of the normal liver tissues. HLA-F expression in HCC lesions was significantly correlated with patient gender (P=0.02), and venous or lymphatic invasion (P=0.02). Patients who were HLA-F-positive had worse survival times than those who were HLA-F-negative (P=0.04). The mean overall survival times for HLA-F-negative and -positive patients were 44.2 months [95% confidence interval (CI), 37.7-50.7] and 33.0 months (95% CI, 25.1-40.8), respectively. Multivariate analysis revealed that HLA-F was an independent prognostic factor for HCC patients with a hazard ratio of 2.1 (95% CI, 1.0-4.4). In conclusion, the present study demonstrated that HLA-F expression was associated with poor survival in HCC patients, and is correlated with tumor cell invasion and metastasis.
