  • Laparoscopic precise segment Ⅳ hepatectomy by guiding of indocyanine green fluorescence imaging via ligamenta teres hepatis: a summary of 6 cases

    ObjectiveTo investigate the clinical feasibility and value of laparoscopic precise segment Ⅳ hepatectomy by guiding of indocyanine green (ICG) fluorescence imaging via ligamenta teres hepatis. MethodThe clinicopathologic data of patients with liver cancer treated in the Department of Liver Surgery of West China Hospital of Sichuan University from January 2017 to December 2021 who underwent precise segment Ⅳ hepatectomy by the guidance of ICG fluorescence imaging through the ligamenta teres hepatis were collected retrospectively. ResultsA total of 6 patients were collected, including 5 males and 1 female. The age ranged from 42 to 78 years. All 6 patients were successfully completed using laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis. The operation time was (200±30) min, the intraoperative bleeding was (100±20) mL, and there were no intraoperative blood transfusion, postoperative liver failure, postoperative pneumonia, incision infection, bile leakage, postoperative bleeding, and other complications. The postoperative hospital stay was (7±2) d. One patient with positive microvascular invasion was found after operation and recurred at 38 months after operation, then treated by radiofrequency ablation and didn’t recur. No patient died during the follow-up period in 6 patients. ConclusionFrom results of limited cases in this study, laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis is safe, feasible, and effective.

  • Analysis of a case of primary squamous cell carcinoma of liver

    ObjectiveTo investigate misdiagnosis of primary squamous cell carcinoma of liver (PSCCL) as cholangiocarcinoma before operation and its clinical manifestations, imaging manifestations, etiology, histological origin, pathological characteristics, diagnosis and differential diagnosis, selection of treatment methods, and prognosis, so as to improve understanding and reasonable diagnosis and treatment of disease.MethodThe clinicopathologic data of a case of PSCCL misdiagnosed as cholangiocarcinoma in the West China Hospital of Sichuan University were analyzed retrospectively.ResultsThe patient was admitted to the West China Hospital of Sichuan University with the right hepatic space occupying. The preoperative imaging examination showed that the patient had the imaging characteristics of hepatic cholangiocarcinoma, then the right hemihepatectomy was performed. The postoperative pathological diagnosis was the PSCCL.ConclusionsPreoperative diagnosis of PSCCL is extremely difficult and it is difficult to differentiate it from primary liver cancer, and it is easy to overlook liver metastasis’s occurrence in other parts of the squamous cell carcinoma, which leads to liver metastasis. It is usually diagnosed by pathological diagnosis after operation, and then original lesions in other parts are excluded by various examinations. PSCCL is treated in a variety of ways, but it’s prognosis is not good. At present, there is no unified treatment principle, most of which are surgery, followed by postoperative radiotherapy and chemotherapy. In most cases, because PSCCL’s etiology is unknown and mechanism is not clear, clinicians can only implement individualized treatment according to patient’s condition.

  • MDT discussion of a case of primary diffuse large B cell lymphoma of liver

    ObjectiveTo investigate the clinical manifestations, imaging manifestations, etiology, histological origin, pathological characteristics, diagnosis and differential diagnosis, selection of treatment methods, and prognosis of primary diffuse large B cell lymphoma of livers (PDLBCLL), so as to improve understanding and reasonable diagnosis and treatment of this kind of disease.MethodThe clinicopathologic data of a case of PDLBCLL diagnosed in the West China Hospital of Sichuan University in June 2019 were analyzed retrospectively.ResultsIt was very difficult to diagnose PDLBCLL preoperatively and to distinguish PDLBCLL from primary liver cancer and other liver space occupying lesions. It was also easy to ignore the possibility of invasion of liver by lymphopoietic tissue tumor, which was often diagnosed by postoperative pathological diagnosis or puncture biopsy, and after the elimination of hematological diseases by various examinations. This patient was admitted to the hospital as a space occupying in right liver. Preoperative imaging examination considered that may be a tumor. After MDT discussion, considering that the nature of the tumor should be confirmed by surgical resection, and then go to the Department of Oncology. Irregular right hemihepatectomy + cholecystectomy + hilar lymphadenectomy + diaphragmatic repair was performed after MDT discussion. The diagnosis of PDLBCLL was confirmed by postoperative pathological examination. The operation duration was about 230 min, and the intraoperative blood loss was about 200 mL. The patient recovered well without complications and was discharged on the 10th day after operation. The patient was followed up for 9 months. The liver and kidney function, electrolytes and abdominal Doppler ultrasound examination were regularly reviewed every month. No obvious abnormality was found in these results.ConclusionsAt present, there is no unified treatment principle, most of them will undergo surgery, chemotherapy, radiotherapy or combined treatment. Due to its unknown etiology and unclear mechanism, clinicians can only implement individualized treatment according to the characteristics of patients’ conditions.
