A lumen-apposing metal stent (LAMS) is a saddle-shaped stent with large flanges at both ends, thereby preventing stent migration and helping with approximation of the adjacent structures. We report the case of a 25-year-old female with remnant choledochal cyst which was successfully treated with LAMS after initial treatment failure with a plastic stent. Although complete excision of the cyst is the definite treatment of choledochal cysts, endoscopic ultrasonography-guided cystoduodenostomy can be considered in cases wherein surgery is not feasible and dysplasia is not present. LAMS may be preferred to plastic stents for effective resolution of remnant choledochal cyst and prevention of ascending infection.

Recently, the trauma patients have been markedly increasing due to the vast increase of traffic accident, industrial disaster, incidental accident and violence. The authors have analysed of 22 patients of thoracic injuries combined with abdominal injuries and summarized as follows. The ratio of male to female was 3.4:1 and their age distribution was from 5 years to 68 years and mean age was 34.4 years. The etiologies of injury were traffic accident, stab wound, fall down and violence. Associated injuries were fractures, bowel perforation, kidney rupture, head injury, liver laceration, spleen rupture and so forth. The modes of treatment were closed thoracostomy, repair of diaphragm, ruptured bowel repair, explo-thoracotomy, splenectomy, hepatic lobectomy in this order of frequency. The postoperative complications were atelectasis, wound infection, pneumonia, empyema, acute renal failure, respiratory failure and bleeding. The mortality rate was 13.6% [3/22 and the causes of death were respiratory failure 1 case, acute renal failure 1 case and hypovolemic shock 1 case.

To treat fulminant hepatic failure (FHF) patients, various extracorporeal bioartificial liver (BAL) systems have been developed. Several requirements should be met for the development of BAL systems: hepatocytes should be cultured in a sufficiently high density; their metabolic functions should be of a sufficiently high level and duration; and the BAL systems module should permit scaling-up and aseptic handling. Several investigators have found that freshly isolated primary hepatocytes can be cultured into three dimensional, tightly packed, freely suspended, multicellular aggregates, or spheroids. These specialized cell structures exhibited enhanced liver specific functions and a prolonged differentiated state compared to cells maintained in a monolayer culture. Cells in spheroids appear to mimic the morphology and ultrastructure of the in vivo liver lobule. The ability of hepatocytes to organize into three-dimensional structures was hypothesized to contribute to their enhanced liver-specific activities. In this study, the ammonia removal rate and urea secretion rate of pig hepatocytes spheroids encapsulated in Ca-alginate bead were determined. A packed-bed bioreactor with encapsulated pig hepatocytes was devised as BAL support system. The efficacy of the system was evaluated in vitro.

N,N-Dimethylformamide (DMF) is globally used as an organic solvent in the production of synthetic leather and resins because of its low volatility, making it an attractive industrial material. Despite its excellent property as a chemical solvent, utilization of DMF is somewhat controversial nowadays due to its hazardous effects on exposed workers in work places. Many toxification cases are being reported globally and the number of cases of liver damage is still increasing in developing countries. On account of this, a series of epidemiologic surveys are being conducted to understand the degrees of liver damage caused by DMF exposure. Furthermore, many investigations have been performed to clarify the mechanism of DMF-induced liver toxicity using both human and experimental animal models. This review summarizes the current occupational cases reported on liver damage from workers exposed to DMF in industrial work places and the research results that account for DMF-induced liver failure and possible carcinogenesis. The findings reviewed here show the synergistic toxicity of DMF exposure with other toxicants, which might occur through complicated but distinct mechanisms, which may extend our knowledge for establishing risk assessments of DMF exposure in industrial work places.

Objectives: To report the reduction of adverse effects of chemotherapy and improvement in the quality of life in recurrent liver metastasis by Korean medicine treatments. Methods: In 2018, a 75-year-old male patient underwent surgery for primary cancer in the ampulla of Vater. In 2021, he was diagnosed with recurrent liver metastasis. Following the failure of tumor treatment with gemcitabine/cisplatin and the development of severe side effects, he decided to discontinue chemotherapy. Subsequently, with a significantly enlarged liver tumor, he resumed capecitabine/oxaliplatin treatment, alongside moxibustion, acupuncture, and herbal prescriptions from August 2021 to August 2023. The changes of chief complaints, abdominal CT, and laboratory findings were investigated. Results: After combined treatment of Korean traditional medicine and chemotherapy, the mass was decreased. Laboratory findings, and chief complaints of hand-foot syndrome, fatigue, abdominal distension, nausea and anorexia were improved. Conclustions: This case study suggests that Korean traditional medicine is effective in enhancing anticancer effects, suppressing the side effects of chemotherapy, and improving general conditions.

Background : Liver cirrhosis is a disease of the liver in which normal cells are replaced by scar tissue. This condition results in the failure of the liver to perform many of its usual functions. Liver cirrhosis includes ascites, jaundice, portal hypertension, varices etc. Objectives : This study was to see if there is a decrease in ascites of liver cirrhosis to under acupuncture and herbal treatment to test their validity. Methods : Measuring the response to treatment of ascites by giving pyengwie-san hap wieryungtang gamibang and treating the patient with acupuncture, these clinical symptoms were observed: weight, abdominal circumference, abdominal SONO, chest X-ray, and lab findings. Results : Over 18 days the daily average loss of weight and abdominal circumference 0.43kg and 0.56cm, respectively. Lab findings of liver functions showed improvement. Conclusions : This report shows a role for acupuncture and herbal treatment for treating ascites in liver cirrhosis.

Liver ischemia-reperfusion injury (IRI) is the main cause of organ dysfunction and failure after liver surgeries including organ transplantation. The mechanism of liver IRI is complex and numerous signals are involved but cellular metabolic disturbances, oxidative stress, and inflammation are considered the major contributors to liver IRI. In addition, the activation of inflammatory signals exacerbates liver IRI by recruiting macrophages, dendritic cells, and neutrophils, and activating NK cells, NKT cells, and cytotoxic T cells. Technological advances enable us to understand the role of specific immune cells during liver IRI. Accordingly, therapeutic strategies to prevent or treat liver IRI have been proposed but no definitive and effective therapies exist yet. This review summarizes the current update on the immune cell functions and discusses therapeutic potentials in liver IRI. A better understanding of this complex and highly dynamic process may allow for the development of innovative therapeutic approaches and optimize patient outcomes.

Trauma remains one of the important sources leading to systemic inflammatory response anti sub-sequent multiple organ failure. Although hepatic microvascular dysfunction occurs during trauma, the mechanism responsible remains unclear. The aim of this study was to investigate the effect of trauma on hepatic vascular stress gene expression. Femur fracture (EFx) was induced by torsion to the femur at midshaft. Liver samples were taken for RT-PCR analysis of mRNA for gtenes of interest: endothelin-1 (ET-1), its receptors $ET_A$ and $ET_B$, nitric oxide synthases (iNOS and eNOS), cyclooxygenase-2 (COX-2), heme oxygenase-1 (HO-1), and tumor necrosis tactor-${\alpha}$ (TNF-${\alpha}$). The expression of ET-1 mRNA was significantly increased by FFx. Expression of mRNA in FFx group showed no change in $ET_A$, $ET_B$, iNOS and HO-1 and showed a slight increase of 2.2-fold and 2.7-fold for eNOS tll1d COX-2, respectively. The level of TNF-${\alpha}$ mRNA significantly increased in FFx group. In conclusion, mild trauma alone causes little change in expression of vasoactive mediators.
