Background. Hepatocellular carcinoma is the most common liver cancer and is a leading cause of cancerrelated death worldwide. Its aggressiveness and extensive dissemination lead to a poor patient prognosis. The 5-year survival rate does not exceed 15 %. Despite advances in imaging techniques, its curable rate remains low, because signs and symptoms of liver cancer do not usually appear until the late stages. There is no standard curative treatment for advanced liver cancer.Description. We present the case of a 56- year-old female patient with stage T3N0M0 hepatocellular carcinoma. The patient had a tumor of 20 cm in diameter and 2400 g in weight. The patient underwent right hemihepatectomy and cryodestruction of the liver stump along the resection margin. No evidence of tumor recurrence was found with a follow-up of 12 years.Conclusion. Cryodestruction of the liver stump along the resection margin increases the potential for a higher cure rate in patients with hepatocellular carcinoma, even in cases of extensive organ damage in the absence of metastasis and tumor ingrowth into surrounding organs.
Целью исследования является изучение результатов внедрения в клиническую практику доступа Мерзликина-Парамоновой. Материал и методы. В эксперименте на 20 трупах проведено изучение топографо-анатомических, пространственных взаимоотношений в ране с учетом критериев оценки по А.Ю. Созон-Ярошевичу. В клинике доступ Мерзликина-Парамоновой применен в лечении 81 пациента с очаговой патологией печени (рак, гемангиома, альвеококкоз), которым выполнены радикальные и паллиативные оперативные вмешательства. Прослежены ближайшие и отдаленные результаты в сроки до 5 лет после лечения. При всех перечисленных вмешательствах предлагаемый доступ обеспечивал достаточный обзор печени, свободу манипуляций в области крупных желчных протоков, сосудов, в том числе и криоинструментами, возможность выполнения лимфодиссекции и комбинированных операций. Результаты. Предложенный доступ для оперативного вмешательства на печени имеет значительные преимущества перед традиционными, обеспечивает хороший обзор для ревизии оперируемого органа как при первичном, так и рецидивном поражении. использование доступа позволило провести более раннюю активизацию больных, снизить количество послеоперационных осложнений за счет меньшего натяжения раны, скорейшего купирования болевого синдрома и снижения внутриабдоминальной гипертензии, что позволило сократить сроки лечения больных. В отдаленном послеоперационном периоде снижалась частота развития послеоперационных грыж за счет меньшего повреждения нервных окончаний передней брюшной стенки. Заключение. Доступ Мерзликина-Парамоновой малотравматичен за счет того, что учитываются иннервация и мышечное строение стенки брюшной полости, а также более физиологичен, что подтверждается низкими показателями осложнений. Хорошая доступность оперируемого органа, возможность для расширения и выполнения радикальных и циторедуктивных операций показали, что доступ создает достаточный простор для ревизии и оперативного вмешательства как в случае первичного, так и метастатического поражения органа. С учетом этого заявленный способ доступа может быть рекомендован для активного внедрения в клиническую практику.Ключевые слова: очаговое поражение печени, рак печени, операционный доступ, хирургическое лечение.
The possibility of using titanium nickelide (TiNi) cryoapplicator in the surgery of nonparasitic cysts and liver hemangiomas was study.Material and methods. The analysis of the results of surgical treatment of patients with the use of TiNi cryoapplicator was carried out in 26 patients with nonparasitic liver cysts and in 31 patients with liver hemangiomas of various localization and diameter.Results. It was proved that the use of a TiNi cryoapplicator is as effective as a stationary cryoinstallation with a constant supply of a cryoagent (liquid nitrogen).Conclusion. The use of TiNi cryoapplicator increases the effectiveness of the action on cysts and hemangiomas of the liver, causing their cryodestruction and preventing the recurrence of these diseases, reduce blood loss and reduce trauma when using laparoscopic cryoprobes. In addition, when using the open access of Merzlikin– Paramonova, it becomes possible to manipulate with less trauma in the area of the diaphragmatic surface of the organ and the caval gates of the liver, which are difficult to access for surgical intervention from traditional incisions, especially when the pathological process is located in 7–8 segments of the liver.
Purpose of the study. To investigate the efficacy of focal destruction tissues of local liver diseases, chole- and hemostasis of created endoscopic cryoapplicator in operations on the liver and gallbladder.Material and methods. Review the results of surgical treatment of 121 patients with various diseases of the liver (tumors, alveococcosis, parasitic and non-parasitic cysts) and gallbladder (chronic and acute cholecystitis) using a new endoscopic porous TiNi cryoapplicator. 49 patients were operated by an open method, 72 - laparoscopically. Hemo-and cholestatic control of the instrument was performed intraoperative and in postoperative period - by clinical condition of patient and by ultrasonography. Efficiency of destruction of focal liver diseases was investigated by histological examinations of surgical materials, is confirmed by the absence of relapses in the period from 4 to 6 years.The results. Cryoapplicator is simple in use, in sterilization, no energy consumption, can be used both in open surgery, particularly in arduous regions of the liver and laparoscopic procedures and, most importantly, patients with artificial cardiac pacemakers.Cryodestruction of the liver stump after its resection and the bed of the gallbladder after cholecystectomy reduces blood loss by 30-40%, and also helps to reduce the number of relapses of the disease. There were not observed bleeding and bile leakage in postoperative period. Histological examination proved picture of avascular necrosis, a violation of tissue structure of subjected to destruction liver focal diseases, death of epithelial lining of non-parasitic cysts and membranes of echinococcal cysts. There were not diseases recurrences in the period from 4 to 6 years.Conclusion. Endoscopic porous TiNi cryoapplicator is simple and convenient in use, it has a good hemo- and cholestatic effects, pronounced effect to local destruction of liver focal diseases, can be recommended for open and laparoscopic operations on liver.
