Liver surgery

BACKGROUND AND PURPOSE: Nonalcoholic fatty liver disease (NAFLD) is a growing problem with a significant burden. Lifestyle modification is the recommended treatment, but researchers are exploring other options. This study focused on the effects of Fumaria parviflora (FP) extracts on NAFLD induced by a high-fat diet in rats. EXPERIMENTAL APPROACH: Thirty-five 10-week-old male Wister-Albino rats were divided into seven groups: normal diet control, high fat diet control, high fat diet with oral normal saline gavage, high fat diet with oral Atorvastatin gavage, and three groups receiving high fat diet with FP extract in 200 mg/kg, 400 mg/kg, and 700 mg/kg...

Takotsubo syndrome (TTS) is a stress-induced cardiomyopathy that causes temporary left ventricular wall motion abnormalities and abrupt reversible heart failure. The incidence of perioperative TTS is proportional to the severity of surgical trauma, the duration of the procedure, and the degree of apparent sympathetic activity. A growing number of articles have discussed TTS after a solid organ transplant (SOT), which is one of the circumstances in which physical and emotional stress are at their highest levels...

INTRODUCTION: Pucker sign is the depression of the liver in the region of the gallbladder due to a high degree of chronic contractive inflammation of the gallbladder. It usually develops in patients who have a delayed cholecystectomy after acute cholecystitis due to a high degree of chronic contractive inflammation of the gallbladder and contraction of the cystic plate. It is an essential finding either preoperatively or intraoperatively as it can act as a stopping rule during cholecystectomy (act as a guide that cholecystectomy will be difficult)...

BACKGROUND: Cytokines/chemokines play essential roles in the occurrence and progression of hepatitis B virus (HBV) infection. This study aimed to observe the expression patterns of 10 related cytokines/chemokines in the serum of healthy individuals, self-limited patients and HBV-infected patients at different stages of disease (chronic hepatitis B (CHB), liver cirrhosis (LC), hepatocellular dysplastic nodules (DNs) and hepatocellular carcinoma (HCC)) and to analyze the relationships of these cytokines/chemokines with disease progression...

AIMS: This study compared the prevalences of metabolic syndrome and of cardiac or kidney comorbidities among patients with hepatocellular carcinoma (HCC) associated with metabolic dysfunction-related fatty liver disease (MAFLD), chronic infection with hepatitis B or C virus (HBV or HCV), or the combination of MAFLD and chronic HBV infection. METHODS: Medical records were retrospectively analyzed for patients with HCC who underwent hepatectomy between March 2013 and March 2023...

BACKGROUND: The proportion of heart failure patients with preserved ejection fraction has been rising over the past decades and has coincided with increases in the prevalence of obesity and metabolic syndrome. The relationship between these interconnected comorbidities and heart failure with preserved ejection fraction (HFpEF) is still poorly understood. This study characterized obesity and metabolic syndrome among real-world patients with HFpEF. METHODS: We identified adults with heart failure in the Veradigm Cardiology Registry, previously the PINNACLE Registry, with a left ventricular ejection fraction measurement ≥ 50% between 01/01/2016 and 12/31/2019...

Von Hippel-Lindau (VHL) disease, an autosomal dominant genetic disorder caused by a germline mutation, is associated with non-functional and slow-growing pancreatic neuroendocrine tumor (PNET) and kidney cancer. We describe the case of a 46 year-old man with a 35 mm mass in the pancreatic head causing stricture of the bile duct and main pancreatic duct, a 55 mm mass in the pancreatic tail causing obstruction of the splenic vein (SV), and multiple masses of > 36 mm on both kidneys...

OBJECTIVE: Obesity-related problems can now be managed with effective nutritional therapy, pharmacotherapy, and surgeries that achieve >10% weight loss. Assessing patient preferences, treatment choices, and factors affecting patients can improve treatment compliance and efficacy. Our aim was to identify factors affecting patient preference and subsequent choice of pharmacotherapy among those seeking treatment for obesity-related disorders. METHODS: A participatory action study using purposeful sampling recruited 33 patients with obesity complications...

PURPOSE: To review the presentation and visual prognostic factors of patients with endogenous endophthalmitis before and after the introduction of microincision vitrectomy surgery (MIVS), at a tertiary referral hospital in Taiwan, over a 21-year period. METHODS: We retrospectively analyzed medical records of patients diagnosed with endogenous endophthalmitis before and after the introduction of MIVS between January 2002 and December 2022. RESULTS: Data were collected from 147 patients...

OBJECTIVE: Aim: to review information resources and analysis of the own experience on this problem for the provision of modern knowledge in the pathogenesis of the pathology, the latest diagnostic and treatment technologies, with consideration of the need to adhere to a single strategy in the management of patients with BA. PATIENTS AND METHODS: Materials and Methods: The analysis of the data regarding the results of existing studies evaluating the clinical benefit and safety of diagnostic and treatment methods in Biliary atresia...

Novel adhesives for biological tissues offer an advanced surgical approach. Here, we report the development and application of solid-state adhesives consisting of porous hydroxyapatite (HAp) biocompatible ceramics as novel internal organ retractors. The operational principles of the porous solid-state adhesives were experimentally established in terms of water migration from biological soft tissues into the pores of the adhesives, and their performance was evaluated on several soft tissues with different hydration states...

BACKGROUND: Nivolumab combination chemotherapy has recently emerged as a potential first-line treatment for patients with unresectable or metastatic gastric cancer (GC). Further research has indicated that R0 resection by conversion surgery could be an effective treatment strategy to improve overall survival. However, there have been limited reports on the successful application of conversion surgery following combination chemotherapy achieving pathological complete response (pCR) in cases of advanced gastric remnant cancer with liver metastasis...

OBJECTIVE: In this paper, a single-hand-operated hepatic pedicle clamp was introduced, and its application value in laparoscopic liver tumor resection was preliminarily discussed.

INTRODUCTION: Approximately 50% of Crohn's disease (CD) patients develop intestinal strictures necessitating surgery. The immune cell distribution in these strictures remains uncharacterized. We aimed to identify the immune cells in intestinal strictures of CD patients. METHODS: During ileocolonic resections, transmural sections of terminal ileum were sampled from 25 CD patients and 10 non-inflammatory bowel disease (IBD) controls. Macroscopically, unaffected, fibrostenotic and inflamed ileum was collected and analysed for immune cell distribution (flow cytometry) and protein expression...

OBJECTIVE: Human immunodeficiency virus infection (HIV+) is associated with a 2-fold increased risk of cardiovascular disease. Increasingly, patients who are HIV + are being evaluated to undergo cardiac surgery. Current risk-adjusted scoring systems, including the Society of Thoracic Surgeons Predicted Risk of Mortality score, fail to stratify HIV + risk. Unfortunately, there exists a paucity of cardiac surgery outcomes data in modern patients who are HIV+. METHODS: We conducted a retrospective review of PearlDiver, an all-payer claims administrative database...

In this editorial review, we comment on the article published in the recent issue of the World Journal of Gastrointestinal Surgery . Carcinoembryonic antigen (CEA) is a fetal glycoprotein and can be secreted in very small amounts from healthy adults after birth. CEA is widely used not only for diagnostic tumor markers but also importantly for the management of some gastrointestinal tumors. The most common clinical use is surveillance for the monitoring of colorectal carcinoma. However, CEA can become elevated in several malign or benign characterized pathologies...

BACKGROUND: Colon cancer is one of the most common malignant tumors of the digestive system. Liver metastasis after colon cancer surgery is the primary cause of death in patients with colon cancer.
