Purpose: The aims of this case series study were to review the 10 patients who were diagnosed with left-sided gallbladder and analyze their anatomic variations in the bile duct, portal vein, and hepatic vessels.
Methods: In this case series study, 10 patients with left-sided gallbladder were retrospectively analyzed at 2 tertiary referral centers between April 2004 and May 2019.
Results: Mean age was 61.1 years; there were 7 women and 3 men. Ten patients underwent laparoscopic cholecystectomy for acute cholecystitis or symptomatic gallbladder stone. The mean operation time was 77.2 minutes. Three ports were used in laparoscopic cholecystectomy procedures. The mean postoperative hospital stay was 3.5 days, and there were no cases of surgery-related morbidity. Two patients had type 1 bile duct and 3 had type 3 bile duct (2 type 3B and 1 type 3A). The right posterior portal vein as the first branch of the main portal vein was observed in all patients. Segment IV branches of the left portal vein crossing over to the segment VIII territory were observed in 7 of the 10 patients.
Conclusion: Although left-sided gallbladder is a very rare disease, it is possible to diagnose it preoperatively and perform laparoscopic cholecystectomy safely by adjusting port position. The common important features of left-sided gallbladder include distribution of the left portal vein crossing over to the right side of the liver and increased size of the left portal vein. These variations may have important clinical implications in the management of hepatic resection including donor hepatectomy.

Background: Non-invasive approach other than conventional endoscopy could be effectively used for screening and monitoring esophageal variceal bleeding (EVB).
Purpose: To retrospectively investigate the role of four-dimensional (4D) flow magnetic resonance imaging (MRI) as an add-on tool to endoscopy for predicting EVB in cirrhotic patients with esophageal varices (EVs).
Material And Methods: A cohort of 109 cirrhotic patients with EVs was divided into four groups: A = negative red color [RC] sign, no EVB, n = 60; B = negative RC sign, EVB, n = 13; C = positive RC sign, no EVB, n = 10; and D = positive RC sign, EVB, n = 26.

Background: Liver cirrhosis accounts for more than 90 % of portal hypertension cases, and the other cases are due to noncirrhotic portal hypertension (NCPH). Variceal bleeding is the most life-threatening complication of portal hypertension and its primary treatment is medical according to the Baveno VII guidelines. This review discusses the evidence on surgical portal decompression for adult patients with NCPH secondary to chronic extrahepatic portal vein obstruction (EHPVO).

During digestion, almost 50% of absorbed essential amino acids (AAs) are metabolised by intestinal tissue, thus not appearing directly in the portal vein. This value, which is referred to as first-pass metabolism, seems high in relation to the overall efficiency of AA use considered in growth models. Experimental studies of first-pass metabolism are complicated due to the presence of numerous metabolic fluxes in the intestine and to the dynamics of digestion and absorption.

This in vivo study introduces a newly developed spirooxindole derivative that is deemed safe and effective as a potential targeted therapy for various cancers. Extensive in vivo investigations, including histopathology, immunohistochemistry, and molecular biology, validated its potential for further preclinical and clinical exploration, necessitating comprehensive examinations of its bioavailability, pharmacodynamics, and pharmacokinetics. Additionally, this study involves the development of a commercially viable proniosomal drug delivery system for the compound, facilitating controlled drug release.

Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.
