INTRODUCTION: Bile duct injuries caused by any reason are a disaster for patients and pose a significant psychological and technical challenge for surgeons. The use of Ligamentum teres hepatis and gallbladder flap as autografts is showing promising results in the repair of bile duct injury. CASE PRESENTATION: This article presents a challenging case of a patient with Mirizzi syndrome who experienced a complex bile duct defect and injury during cholecystectomy. We describe the successful reconstruction of the bile duct using ligamentum teres hepatis and remnant gallbladder flap simultaneously...

INTRODUCTION: Insulinoma-associated protein 1 (INSM1) is an immunohistochemical marker commonly used to confirm cytomorphological concordant neuroendocrine tumors/carcinomas (NETs/NECs), demonstrating high utility in small samples. Previous reports have suggested comparable INSM1 staining in CytoLyt-fixed cell blocks and formalin-fixed surgical pathology specimens. This study aimed to assess INSM1 immunoreactivity using both fixation methods and investigate potential factors contributing to its variable expression...

The distal bile duct was isolated and transected with a frozen section examination confirming the absence of malignancy. Attention was then shifted to constructing a 60 cm Roux limb by first identifying and transecting the proximal jejunum 40 cm from the ligamentum of Treitz. A side-to-side stapled jejunojejunostomy anastomosis was completed. The Roux limb was transposed toward the porta hepatis through an antecolic approach.

A 10-year-old Cocker spaniel presented with lethargy. Triple-phase computed tomography was obtained with a contrast test bolus at the level of porta hepatis, which revealed a right lower abdominal mass. The mass was not connected to other abdominal organs; however, a linear structure was observed connecting the splenic hilum to the mass, which was suspected to be the feeding vessel. The arterial phase image was obtained again with a contrast bolus at the level of the celiac artery. A prominent contrast-enhanced feeding artery originating from the splenic artery to the mass was observed...

A 72-year-old man was referred to our hospital for the examination of a pancreatic head mass. Abdominal computed tomography revealed a contrasted 8-cm-diameter tumor extending from the dorsal pancreatic head to the porta hepatis. The preoperative diagnosis was challenging due to the absence of specific imaging findings and the inability to perform a biopsy. Positron emission tomography/computed tomography and diffusion-weighted imaging suggested a malignant tumor originating from the organs surrounding the pancreatic head...

Introduction The liver is the largest gland in the body and shows wide variation in surface features. Knowledge of external features is essential for radiological investigations and during abdominal surgeries. Morphological variation of the liver should be considered for better patient outcomes. Segmental anatomy has received more attention for segmental resection and transplant surgery. The present study aimed to determine variations in external features of the liver and indicate its clinical importance...

Cystic tumors account for 15% of pancreatic tumors. Of these, serous microcystic adenomas represent 1-2% of pancreatic exocrine neoplasms. While typically benign, a small percentage possess malignant potential. Given imaging improvements, serous cystadenomas are being identified more frequently. A 63-year-old female was admitted with complaints of jaundice and unintentional weight loss. Abdominal computed tomography scan showed a 16 cm obstructive pancreatic mass near the porta hepatis region. Endoscopic ultrasonography and fine needle aspiration biopsy indicated a large pancreatic head cystic mass favoring serous microcystadenoma causing biliary and some pyloric obstruction...

Peliosis hepatis (PH) and sclerosing angiomatoid nodular transformation of the spleen are uncommon benign lesions. Diagnosis can be difficult in some patients. Herein, we present the case of a 28-year-old woman referred with abdominal pain who had spleen lesions. 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography revealed multiple non-FDG avid lesions in the liver and hypermetabolic lesions in the spleen. In addition, abdominal magnetic resonance imaging was performed. Histopathology revealed sclerosing angiomatoid nodular transformation in the spleen and PH in the liver...

The ectopic liver lobe is a rare anomaly and is most frequently reported as a solitary mass. Herein, we report a case of multiple (two) ectopic liver lobes detected at an autopsy. A Japanese man in his 70s died of an infectious disease associated with acquired immunodeficiency syndrome (AIDS). Autopsy revealed the incidental finding of two 1-cm masses, located anterior to the inferior vena cava. Both masses were composed of liver tissue and had internal microscopic structures resembling the porta hepatis, consisting of an outflow bile duct and blood vessels...

Few instances of neoplastic formations in the liver of chinchillas have been found, even though the species is widely used in different scientific experiments. In the present article we investigate the anatomical features of the chinchilla's liver using CT and three dimension (3D) imaging. For the trials we used 12 (six males and six females) clinically healthy chinchillas all at 18 months of age. The animals were positioned in dorsal recumbency. We used Th8 to L2 vertebrae and the sternum as bone markers for the transverse CT study...

A 62-year-old male patient underwent pancreaticoduodenectomy with modified Child reconstruction for distal cholangiocarcinoma. After eight years, a contrast-enhanced computed tomography (CT) revealed a recurrent lesion at the biliojejunal anastomosis, and a biliary stent was placed for obstructive cholangitis in the right posterior segment of the liver. A right hepatectomy was planned for a local recurrent lesion;thus, percutaneous transhepatic portal embolization was performed on the portal vein's right branch to enlarge the left liver...

INTRODUCTION: Homeopathic medicines have been used for decades in the prevention and treatment of infectious diseases. However, the preventive efficacy of specific homeopathic medicines in COVID-19 is not well characterised. This study aimed to evaluate the comparative efficacy of prespecified homeopathic medicines in preventing COVID-19. METHODS: A community-based, double-blind, randomized, placebo-controlled trial was conducted on 4,034 participants residing in Ward no...

BACKGROUND: To evaluate the impact of tumor size on the perioperative and long-term outcomes of liver resection for hepatocellular carcinoma (HCC). METHODS: We reviewed the patients' data who underwent liver resection for HCC between November 2009 and 2019. Patients were divided into 3 groups according to the tumor size. Group I: HCC < 5 cm, Group II: HCC between 5 to 10 cm, and Group III: HCC ≥ 10 cm in size...

Rare and sometimes fatal, spontaneous hepatic rupture (SHR) is frequently documented in conjunction with various benign and malignant hepatic tumors, peliosis hepatis (PH), amyloidosis, and polyarteritis nodosa. PH is a rare disease characterized by the presence of sinusoidal dilation and blood-filled cysts throughout the hepatic parenchyma. Handling and identifying this condition can be challenging, particularly in the absence of a history of liver cirrhosis or a tumor. The present case involves a 61-year-old male with a SHR and PH, accompanied by a significant history of end-stage renal disease (ESRD) over the past year...

OBJECTIVE: Metastases in the supragastric lesser sac (SGLS) are not only occult but are also barriers to complete resection of ovarian cancer. We describe a cohort of patients with SGLS disease undergoing debulking surgery. METHODS: We identified all patients who underwent evaluation and eventual resection of SGLS disease as part of cytoreductive surgery for stage IIIC-IVB high-grade epithelial ovarian cancer at our institution from January 2018 to August 2022. RESULTS: Thirty-three of 286 patients (11...

BACKGROUND: Transmesenteric access for portal vein reconstruction and transjugular intrahepatic portosystemic shunt allows for intervention in patients with unfavorable anatomy and can be performed via multiple methods but may be difficult to obtain in patients with complex anatomy. CASE PRESENTATION: We present a case report describing a method of obtaining transmesenteric access in the porta hepatis to facilitate direct intrahepatic portosystemic shunt creation in a young patient with recurrent variceal bleeding...

Hepatic artery pseudoaneurysms are an uncommon complication of blunt hepatic trauma typically presenting in a delayed fashion. A 40-year-old male presented to a trauma centre after a 6-metre fall from a construction site with multiple injuries including a grade IV liver laceration centred around the porta hepatis. This liver injury was managed non-operatively. On day sixteen of admission, he had a sudden cardiac arrest from haemorrhagic shock with a subsequent CT demonstrating a ruptured extrahepatic proper hepatic artery pseudoaneurysm...

T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is an extremely rare and aggressive subtype of diffuse large B-cell lymphoma (DLBCL) that typically presents in middle-aged patients and carries a poor prognosis. Hypercalcemia presenting as the initial manifestation of the disease is rare, with only one other case reported in the literature. We report a case of a 90-year-old male who presented with progressive lethargy and unintentional weight loss. Initial workup showed elevated serum calcium of 14.6 mg/dL, corrected for albumin, and creatinine of 1...

BACKGROUND: Gastroduodenal artery (GDA) stump erosion hemorrhage is a fatal complication after pancreaticoduodenectomy. This study aimed to determine whether GDA stump wrapping with the teres hepatis ligament during pancreaticoduodenectomy decreased the incidence of postpancreatectomy hemorrhage (PPH). METHODS: We reviewed 307 patients who had undergone pancreaticoduodenectomy between March 2019 and June 2022. The patients were divided into two groups according to application of GDA stump wrapping with the teres hepatis ligament: GDA wrapping group (165 patients) and no-wrapping group (142 patients)...

Natural bioactive compounds (NBCs) are widely used in clinical treatment. For example, Tripterygium wilfordii Hook f. is commonly known in China as Lei-Gong-Teng which means thunder god vine. This herb is widely distributed in Eastern and Southern China, Korea, and Japan. The natural bioactive compounds of this herb can be extracted and made into tripterygium glycoside tablets. It is one of the most commonly used and effective traditional Chinese herbal medicines against rheumatoid arthritis (RA), nephrotic syndrome (NS), autoimmune hepatis (AIH), and so on...
