Abstract Background Performing major hepatectomy for patients with marginal hepatic function is challenging. In some cases, the procedure is contraindicated owing to the threat of postoperative liver failure. In this case report, we present the first case of marginal liver function (indocyanine green clearance retention rate at 15 min [ICGR15]: 28%) successfully treated with right hepatectomy, resulting in total caudate lobe preservation. Case presentation A 71-year-old man was diagnosed with sigmoid colon cancer with three liver metastases (S5, S7, and S8). All of metastatic lesions shrunk after chemotherapy, but his ICGR15 and indocyanine green clearance rate (ICGK) were 21% and 0.12, respectively. Moreover, the remnant liver volume was only 39%. Therefore, portal venous embolism (PVE) of the right portal vein was suggested. Portography showed divergence of the considerably preserved right caudate lobe branch (PV1R) from the root of the right portal vein. The liver function was reevaluated 18 days after PVE was suggested. During this time, the ICGR15 (21–28%) and ICGK rate (0.12–0.10) deteriorated. The right caudate lobe was significantly enlarged; thus, a total caudate lobe-preserving hepatectomy (TCPRx) was performed. Patients eligible for TCPRx included those with (1) hepatocellular carcinoma or metastatic liver cancer, (2) no tumor in the caudate lobe, (3) marginal liver function (ICG Krem greater than 0.05 if TCPRx was adapted; otherwise, less than 0.05) and Child–Pugh classification category A, and (4) preserved PV1R and right caudate bile duct branch. The procedure was performed through (A) precise estimation of the remnant liver volume preoperatively, (B) repeated intraoperative cholangiography to confirm the biliary branch of the right caudate lobe (B1R) conservation, and (C) stapler division of posterior and anterior Glisson’s pedicles laterally to avoid injuries to the PV1R and B1R. Conclusions Right hepatectomy with total caudate lobe preservation, following PVE, was a safe and viable surgical technique for patients with marginal liver function.

Majority of interventional procedures are made at the porta hepatis, which has a different location on the visceral surface of the liver. Objective. To describe the location of the porta hepatis in respect of the borders of the visceral surface and separate lobes of the liver. Material and methods. Sixty-four human livers were obtained at autopsy (mean age, 45 years). We chose the point of the crossing of longitudinal and transversal lines of the porta hepatis, which was considered as center of the porta hepatis. The distances from the center of the porta hepatis to the border of the visceral surface every 10 degrees with protractor and ruler and the angles of anatomical structures were measured. Additionally, the borders of lobes were assessed. Results. We found that center of the porta hepatis is located approximately 11.6±2.8 cm from the border of the visceral liver surface. The location of center of the porta hepatis was 11.6±1.1 cm from the border of left lobe, 9.7±1.5 cm from the border of quadrate lobe, 12.3±1.2 cm from the border of right lobe, and 7.4±1.0 cm from the border of caudate lobe. All distances were statistically significant (P<0.05). An angle of the fissure for round ligament was 50.5°, of the fossa of gallbladder – 102°, of the groove of vena cava inferior – 266°, and of the fissure for ligamentum venosum – 293°. The borders of the right, left, quadrate, and caudate liver lobe covered 45.6%, 32.6%, 14.3%, and 7.5% of the perimeter of visceral surface border, respectively. Conclusions. The center of the porta hepatis can help to characterize precisely the position of the porta hepatis on the visceral surface of the liver.

The etiology of hepatic rupture is usually secondary to trauma, and hepatic rupture induced by spontaneous intrahepatic hematoma is clinically rare. We describe here a 61-year-old female patient who was transferred to our hospital with hepatic rupture induced by spontaneous intrahepatic hematoma. The patient had no history of trauma and had a history of systemic lupus erythematosus for five years, taking a daily dose of 5 mg prednisone for treatment. The patients experienced durative blunt acute right upper abdominal pain one day after satiation, which aggravated in two hours, accompanied by dizziness and sweating. Preoperative diagnosis was rupture of the liver mass. Laparotomy revealed 2500 mL fluid consisting of a mixture of blood and clot in the peritoneal cavity. A 3.5 cm × 2.5 cm rupture was discovered on the hepatic caudate lobe near the vena cava with active arterial bleeding, and a 5  × 6 cm hematoma was reached on the right posterior lobe of the liver. Abdominal computed tomography (CT) and laparotomy revealed spontaneous rupture of intrahepatic hematoma with hemorrhagic shock. The patient was successfully managed by suturing the rupture of the hepatic caudate lobe and clearing part of the hematoma. The postoperative course was uneventful, and the patient was discharged after two weeks of hospitalization.

Objective: To find out gross anatomical variations of embalmed cadaveric livers. Methods: Present study was conducted in dissection halls of Anatomy departments of Allama Iqbal Medical College, Lahore, Sahiwal Medical College, Sahiwal and Fatima Jinnah Medical University, Lahore during 2016-2019. In this study, 74 livers were dissected out from embalmed cadavers and preserved in 10% formalin. Different morphological variations were observed in livers which included presence of accessory lobes, accessory sulci, notches, changes in size and shape of lobes. Liver specimens were photographed and classified according to Netter's classification of morphological variations of liver. Results: The hepatic morphological variations observed included accessory fissures in the right, left, caudate and quadrate lobes of the liver, accessory lobes, elongated left lobe, hypoplastic left lobe, multiple deep diaphragmatic sulci, pons hepatis, Reidel's lobe, notched borders and bilobed caudate lobe. Conclusion: The knowledge of various variations in morphology of cadaveric livers may help the radiologists to make accurate interpretation of the radiological images, thus minimizing the chances of incorrect reporting. It may also be helpful to the hepatobiliary surgeons to be aware of the morphological variations on the liver surface to avoid surgical complications. Key Words: Embalmed cadaveric livers, accessory lobes, accessory fissures
