ABSTRACT

RESUMEN Antecedentes: la cirugía hepática ha evolucionado con el correr del tiempo. No existe bibliografía publicada sobre experiencia previa de hepatectomía en Corrientes. Nuestro grupo de trabajo se desenvuelve en el ámbito público y privado. Objetivo: describir los resultados iniciales de una serie consecutiva de pacientes con hepatectomías de distinta extensión, por el mismo equipo quirúrgico. Material y métodos: trabajo retrospectivo, observacional, descriptivo, sobre datos de las historias clínicas y libros de quirófano de pacientes con hepatectomías realizadas entre septiembre de 2019 y enero de 2023, en la práctica pública y privada. Resultados: fueron intervenidos 27 pacientes, con media de edad 53 años (25-72); 16 eran mujeres. El abordaje fue convencional en 25 casos y laparoscópico en 2. Se realizaron 4 hepatectomías mayores y 23 menores. Los diagnósticos fueron de patología maligna en 22 oportunidades y benigna en 5. La sobrevida a los 90 días fue de 96,2%. La mortalidad fue de 1 paciente (3,7%). Con respecto a las complicaciones, 2 pacientes (7,4%) presentaron abscesos hepáticos en el posoperatorio, 2 pacientes (7,4%) requirieron reintervención quirúrgica por sangrado, con buena evolución posterior y alta hospitalaria. Conclusión: la morbimortalidad en la serie descripta estuvo en relación con lo comunicado por otros autores.


ABSTRACT Background: Liver surgery has evolved over time. There are no prior publications on the experience of liver surgery in the province of Corrientes. Our work group operates in both the public and private sectors. Objective: The aim of this study was to describe the initial results of a consecutive series of patients undergoing different types of liver resections, performed by the same surgical team. Material and methods: We conducted a retrospective, observational, and descriptive study based on data from the medical records and operating room records of patients undergoing liver resection at public and private institutions from September 2019 to January 2023. Results: A total of 27 patients were operated on; mean age was 53 years (25-72) and 16 were women. We used the conventional approach in 25 cases and laparoscopy in 2. Four procedures were major liver resections and 23 were minor liver resections, The diagnoses were cancer in 22 cases and benign conditions in 5. Survival at 90 days was 96.2% One patient died (3.7%). The complications included postoperative liver abscesses in 2 patients (7.4%) and re-operation due to bleeding in 2 patients (7.4%), who had a subsequent favorable course and were discharged from the hospital. Conclusion: The morbidity and mortality in the described series were similar to those reported by other authors.

ABSTRACT

RESUMEN Los tumores neuroendocrinos generalmente se originan en el tracto digestivo o páncreas, desarrollando metástasis hepática a lo largo de su evolución. La presencia de un tumor neuroendocrino primario de hígado es motivo de controversia y de muy escasa casuística. Presentamos el caso de un tumor neuroendocrino primario de hígado confirmado por estudio anatomo-patológico e imágenes. La paciente fue sometida a dos resecciones hepáticas mayores, preservando sólo el segmento IV.


ABSTRACT Neuroendocrine tumors generally originate in the digestive tract or pancreas, developing liver metastases throughout their evolution. The presence of a primary neuroendocrine tumor of the liver is still controversial and there are very few cases. We present a case of a primary neuroendocrine tumor of the liver confirmed by anatomo-pathological study and images. The patient underwent two major liver resections, lastly preserving only segment IV.

ABSTRACT

Introducción: La anatomía hepática siempre ha sido un reto por su complejidad y variabilidad. En los últimos años, el abaratamiento de los costes ha permitido la generación de modelos 3D individualizados para cada paciente que pueden facilitar el abordaje quirúrgico de las lesiones. El objetivo principal fue determinar la utilidad del modelado 3D preoperatorio para la planificación quirúrgica en pacientes con lesiones hepáticas. Métodos: Se trata de un estudio de casos de 38 pacientes intervenidos por lesiones hepáticas múltiples ocupantes de espacio, en el cual, en un grupo seleccionado, en 19 pacientes se utilizó un modelo impreso 3D para planificar la cirugía (grupo 3D) y el otro grupo sin el modelo impreso 3D (grupo control). Resultados: Se observó una diferencia de medias significativa en el número de lesiones; mayor en el grupo 3D al realizar el test de Wilcoxon (p < 0,001) y un mayor número de casos con afectación vascular en este mismo grupo al realizar Chi cuadrado Pearson (p = 0,008). El resto de variables no mostraron diferencias estadísticamente significativas. A pesar de esto, la mortalidad se redujo a 0 cuando se usan modelos impresos en 3D. Conclusión: La impresión 3D permite planear, de manera más precisa, cirugías complejas del hígado, ayuda a la inclusión y exclusión de los pacientes para la cirugía, disminuyendo el tiempo de la sala de operaciones, la posterior hospitalización y las complicaciones quirúrgicas.


Introduction: Liver anatomy has always been a challenge due to its complexity and variability. In recent years, lower costs has allowed the generation of individualized 3D models for each patient, which can facilitate the surgical approach to liver lesions. The main objective was to determine usefulness of preoperative 3D modeling for surgical planning in patients with liver lesions. Methods: Quasi-experimental before-after study. 19 cases were included in which surgery was planned using a 3D printed model (13 bilobar hepatectomies, 3 of them with vascular involvement, and 6 unilobar hepatectomies, 1 of them with vascular involvement), and another 19 cases whose planning was carried out without a 3D printed model (7 bilobar segmental hepatic resections and 12 unilobar segmental resections. None of these cases had vascular involvement). Results: A significant difference in mean lesion count was observed, higher in the group of cases when performing the Wilcoxon test (p < 0.001), and a higher number of cases with vascular involvement in the same group when performing the Pearson chi-square test (p = 0.008). The rest of the variables did not show statistically significant differences. Despite this, mortality was reduced to 0 when 3D printed models were used. Conclusion: 3D printing allows for more precise planning of complex liver surgeries, helps with the inclusion and exclusion of patients for surgery, reduces operating room time, postoperative hospitalization, and surgical complications.

ABSTRACT

Introducción. Las malformaciones linfáticas quísticas, también llamadas linfangiomas quísticos, aparecen muy raramente de forma aislada en el hígado. Casos clínicos. Se presentan dos pacientes femeninas de edad preescolar con marcada hepatomegalia, dependiente de lesiones quísticas multitabicadas, secundarias a malformación linfática quística gigante del hígado, que fueron tratadas en el Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Resultados. En ambos casos el diagnóstico se apoyó en los estudios de imágenes, la laparoscopia y el análisis histopatológico. En un caso el tratamiento fue la hepatectomía derecha, mientras que en el otro se empleó la escleroterapia, ambas con evolución favorable. Conclusión. A pesar de su rareza, este diagnóstico no debe obviarse ante un paciente pediátrico con lesiones hepáticas quísticas. El tratamiento de elección es la resección quirúrgica, pero su indicación y envergadura debe valorarse de forma individualizada


Introduction. Cystic lymphatic malformations, also called cystic lymphangiomas, are very rarely found in the liver. Clinical cases. Two pediatric female preschool-age patients. presented with hepatomegaly due to multi-septated cystic lesions of the liver, who received treatment at Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Results. We report two pediatric cases with giant cystic lymphatic malformation of the liver. In both cases, the diagnosis were based on imaging, laparoscopy and pathology. In one case the treatment was right hepatectomy, whereas in the other, sclerotherapy was performed, both with a favorable outcome. Conclusion. Despite its rarity, this diagnosis should be considered in pediatric patients with hepatic cystic lesions. The recommended treatment is surgical resection, but its indication and extent should be assessed individually for each patient.

ABSTRACT

Hepatic echinococcosis is a chronic parasitic disease, which is caused by the larvae of Echinococcus multilocularis. It has a high risk of disability and mortality, which is also known as "parasite cancer". In clinical practice, hepatic echinococcosis can be divided into hepatic alveolar echinococcosis and hepatic cystic echinococcosis. Hepatic echinococcosis is widely prevalent worldwide. It mainly occurs in the populations residing agricultural and pastoral areas in western China, posing significant threats to the quality of life of local residents. At present, surgery is the main treatment for hepatic echinococcosis in clinical settings. With rapid development of surgical diagnosis and treatment technology and deepening understanding of hepatic echinococcosis, diagnosis and treatment regimens have also been constantly improved. In this article, research progresses on the diagnosis and treatment of hepatic alveolar echinococcosis were reviewed, aiming to provide reference for clinicians, deliver early diagnosis and treatment, mitigate adverse effects of this disease upon patients and improve clinical prognosis.

ABSTRACT

Objective:To assess the long-term outcome of sequential radical surgery after immune combined with targeted therapy for patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 100 patients with initially unresectable HCC undergoing sequential radical surgery after immune combined with targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery of Chinese PLA General Hospital from December 2018 to August 2023 were prospectively collected, including 87 males and 13 females, with a median age of 55 (24-73) years. The pre-treatment tumor staging was determined using the China liver cancer staging (CNLC). The efficacy of immune combined with targeted therapy was accessed using the modified response evaluation criteria in solid tumor (mRECIST). The cycles of immune combined with targeted therapy were analyzed. The tumor residual of resected tissue was analyzed through a standard pathological protocol. The prognosis was analyzed using the Kaplan-Meier method.Results:Upon initial diagnosis, there were 46 cases (46.0%) staged CNLC-Ⅲa and 40 (40.0%) staged CNLC-Ⅲb. There were also 14 cases (14.0%) staged CNLC-Ⅰb, Ⅱa, and Ⅱb who underwent immune combined with targeted therapy due to rupture of tumor or insufficient liver remnant. All patients received a median of 5 (3-28) cycles of immune combined with targeted therapy and underwent radical surgery after successful conversion. According to mRECIST, 14 (14.0%) were determined as complete remission, 63 (63.0%) as partial remission, 18 (18.0%) as stable disease, and 5 (5.0%) as disease progression. Of 24 (24.0%) were defined as pathologically complete remission by postoperative pathology. Furthermore, pathological tumor residue was less than 10% in 61 (61.0%) cases and less than 50% in 82 (82.0%) cases. The 1, 3, and 5 year-overall survival rates of patients were 98.0%, 83.1%, and 74.5%, respectively. The 1, 2 and 3 year-recurrence-free survival rates were 67.5%, 54.8%, and 49.6%, respectively.Conclusion:Sequential radical surgery after immune combined with targeted therapy benefits the long-term survival of patients with initially unresectable HCC.

ABSTRACT

Objective:To evaluate the feasibility of abandoning prophylactic abdominal drainage in patients undergoing minimally invasive minor hepatectomy based on a propensity score matching (PSM) study.Methods:Retrospective review of a prospectively collected database of patients undergoing minimally invasive minor hepatectomy from July 2022 to May 2023 at the Department of Hepatopancreatobiliary Surgery and Minimally Invasive Surgery, Zhejiang Provincial People's Hospital. A total of 108 patients were enrolled, including 48 males and 60 females, aged (60.8±13.7) years old. According to whether the abdominal drainage tube was prophylactically placed intraoperatively, patients were divided into two groups: the drainage group (with prophylactic placement of abdominal drainage tubes, n=76); the no-drainage group (without prophylactic placement of abdominal drainage tubes, n=32). PSM was used to compare the perioperative data between the groups, including extent of liver resection, intraoperative blood loss, operative time, and postoperative complications. Postoperative survival status within 90 days was followed up through telephone review. Results:Before PSM, the two groups differed significantly on age and the history of hypertension (both P<0.05). After PSM, there were 23 patients in each group. Patients in the two groups showed comparable results regarding the intraoperative parameters including the surgical method, pathological types, the number and maxium diameter of hepatic lesions, the extent and complexity of liver resection, and the duration of hepatic inflow occlusion (all P>0.05). No postoperative intra-abdominal bleeding occurred in either group. The incidences of postoperative complications were comparable between the groups, including fever, bile leakage, incision infection, and abdominal acupuncture for drainage (all P>0.05). After PSM, compared to patients wothout prophylactic abdominal drainage, prophylactic abdominal drainage group showed a decreased white blood cell counts on postoperative day 1 [9.39(6.30, 10.58)×10 12/L vs. 13.19(10.15, 14.90)×10 12 /L, P=0.006] and a shorter length of postoperative hospital stay [4(3, 5) d vs. 5(4, 5) d, P=0.033]. No postoperative death within 90 days occurred in either group. Conclusion:In minimally invasive minor hepatectomy, abandoning prophylactic abdominal drainage could be feasible, which facilitates fast recovery without increasing the incidence of postoperative fever, perihepatic fluid accumulation and postoperative abdominal acupuncture for drainage.

ABSTRACT

Objective:To study the feasibility of laparoscopic anatomical hepatectomy of segment VII for hepatocellular carcinoma (HCC) with dorsal-ventral combined approach.Methods:Clinical data of 23 patients with HCC undergoing laparoscopic anatomical hepatectomy of segment VII with dorsal-ventral combined approach in Jiangnan University Affiliated Hospital from December 2020 to April 2023 were retrospectively collected, including 11 males and 12 females, aged (58.5±7.9) years old. The patient's perio-perative data, postoperative complications, and follow-ups were analyzed.Results:All patients underwent the surgery successfully without conversion to laparotomy. The operation time was (286.7±63.4) min, the amount of intraoperative blood loss [ M( Q1, Q3)] was 200(150, 400) ml without blood transfusion. There were no major complications such as abdominal bleeding, bile leakage, liver failure or abdominal infection. Two cases had right pleural effusion and were managed with thoracic drainage. The patients could ambulate on postoperative day 2, and the postoperative hospital stay was (9.36±1.72) d. The diameter of the lesion was (4.38±1.42) cm. The serum level of alpha fetoprotein (AFP) three months after surgery was (3.26±0.93) ng/ml, lower than the preoperative baseline (46.75±9.43) ng/ml ( t=38.24, P=0.008). All patients showed normal serum levels of AFP and there were no tumor recurrence or metastasis during postoperative follow-ups. Conclusion:Laparoscopic anatomical hepatectomy of segment VII for HCC with dorsal-ventral combined approach is feasible and worth spreading.

ABSTRACT

Objective To evaluate the predictive value of functional liver imaging score(FLIS)based on preoperative gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI for post-hepatectomy liver failure(PHLF)in patients with hepatocellular carcinoma(HCC).Methods The data of HCC patients who underwent extensive hepatectomy and preoperative Gd-EOB-DTPA enhanced MRI were analyzed retrospectively.The FLIS was scored based on the three features including liver parenchyma enhancement,biliary excretion and portal vein signal enhancement in hepatobiliary phase images,and the consistency between different observers was evaluated.Logistic regression model and receiver operating characteristic(ROC)curve were used to analyze the ability of FLIS to predict the PHLF.Results PHLF occurred in 29 of 120 HCC patients(24.2%).The intraclass correlation coefficient(ICC)of FLIS evaluated by two observers was 0.944.Multivariate logistic regression analysis showed that FLIS was an independent predictor of PHLF of HCC patients[odds ratio(OR)0.520,95%confidence interval(CI)0.355-0.726;P<0.001].The area under the curve(AUC)of FLIS for predicting the PHLF was 0.709,the optimal diagnostic threshold was 4,and the corresponding sensitivity and specificity were 78.0%and 58.6%.Conclusion Preoperative FLIS can predict the PHLF of HCC patients,which may help to make more accurate treatment plans for HCC patients.

ABSTRACT

Objective:To investigate the influencing of portal vein embolization (PVE) and PVE combined with transcatheter arterial chemoembolization (TACE) on secondary hepatectomy and prognosis of patients with initially unresectable hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 102 patients with initially unresectable HCC who were admitted to the Third Affiliated Hospital of Naval Medical University from October 26,2015 to December 31,2022 were collected. There were 82 males and 20 females, aged 52(range,25?73)years. Of 102 patients, 72 cases undergoing PVE combined with TACE were set as the PVE+TACE group, and 30 cases undergoing PVE were set as the PVE group. Observation indicators: (1) surgical resection rate of secondary hepatectomy and increase of future liver remnant (FLR); (2) situations of secondary hepatectomy; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Results:(1) Surgical resection rate of secondary hepatectomy and increase of FLR. The surgical resection rate of secondary hepatectomy in the PVE+TACE group and the PVE group were 72.2%(52/72) and 53.3%(16/30), respectively, showing no significant difference between the two groups ( χ2=3.400, P>0.05). The surgical waiting time, increasing volume of FLR, growth rate of FLR in the 52 patients of PVE+TACE group receiving secon-dary hepatectomy were 20(range, 14?140)days, 140(range, 62?424)mL, 9.8(range, 1.5?26.5)mL/day, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 16(range, 12?35)days, 160(range, 95?408)mL, 10.5(range, 1.2?28.0)mL/day, respectively. There was no significant difference in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=1.830, 1.498, 1.266, P>0.05). (2) Situations of secondary hepatectomy. The operation time, rate of tumor necrosis (>90%, 60%?90%,<60%), cases with complications ≥ grade Ⅲa in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 200(range, 125?420)minutes, 8, 4, 40, 28, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 170(range, 105?320)minutes, 0, 0, 16, 4, respectively. There were significant differences in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=2.132, ?2.093, χ2=4.087, P<0.05). (3) Follow-up. Sixty-eight patients who completed the surgery were followed up for 40(range, 10?84)months. The 1-, 3-, 5-year recurrence free survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 73.0%, 53.3%, 35.4%, respectively. The above indicators in the 16 patients of PVE group were 62.5%, 37.5%, 18.8%, respectively. There was a significant difference in the recurrence free survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.035, P<0.05). The 1-, 3-, 5-year overall survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 82.5%, 61.2%, 36.6%, respectively. The above indica-tors in the 16 patients of PVE group receiving secondary hepatectomy were 68.8%, 41.7%,20.8%, respectively. There was a significant difference in the overall survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.767, P<0.05). Conclusion:Compared with PVE, PVE+TACE as stage Ⅰ surgery can increase the surgical resection rate of secondary hepatec-tomy and the recurrence free survival rate of patients with initially unresectable HCC, prolong the long-term survival time, but not influence the growth rate of FLR.

ABSTRACT

Objective:To investigate the efficacy and value of preemptive analgesia in older adult patients undergoing laparoscopic hepatectomy.Methods:A total of 150 older adult patients with liver cancer, who underwent laparoscopic hepatectomy at The 2 nd Affiliated Hospital of Wenzhou Medical University between July 2019 and April 2020, were randomly assigned to two groups: a control group ( n = 75) and an observation group ( n = 75) using the random number table method. The control group received postoperative analgesia with parecoxib sodium, while the observation group received preemptive analgesia with parecoxib sodium. A comparative analysis was conducted between the control and observation groups in terms of the Numerical Rating Scale (NRS) scores at 8, 12, and 24 hours postoperatively, postoperative recovery, length of hospital stay, and overall cost. Results:There were no statistically significant differences in operation time, dosage of Sufentanil 24 hours postoperatively, or the total and effective usage counts of patient-controlled intravenous analgesia with Sufentanil between the control and observation groups (both P > 0.05). However, the NRS scores of the observation group were significantly lower than those of the control group at 8, 12, and 24 hours postoperatively. Specifically, the NRS scores of the observation group were (4.38 ± 1.24) points, (3.41 ± 0.19) points, and (2.90 ± 0.17) points, respectively, while those of the control group were (5.24 ± 1.01) points, (4.65 ± 1.24) points, and (3.32 ± 1.00) points, respectively ( t = 4.66, 8.56, 3.59, all P < 0.001). Patients in the observation group exhibited significantly more frequent off-bed activities [(2.62 ± 1.24) times], a notably longer cumulative duration of off-bed activities [(1.36 ± 0.20) hours], and a significantly shorter duration of first anal exhaust [(13.50 ± 1.27) hours] compared with those in the control group [(1.06 ± 0.12) times, (0.36 ± 0.09) hours, (20.10 ± 2.16) hours, t = -10.84, -39.49, 22.81, all P < 0.001]. Furthermore, the observation group demonstrated a shorter postoperative hospital stay [(8.90 ± 1.34) days], lower hospitalization costs [(55.8 ± 2.1) thousand yuan], and higher patient satisfaction scores [(88.98 ± 5.64) points] compared with the control group [(11.15 ± 1.29) days, (59.4 ± 6.2) thousand yuan, (72.16 ± 3.26) points, t = 10.48, 4.76, -22.36, all P < 0.001]. Conclusion:The implementation of preemptive analgesia intervention among older adult patients undergoing laparoscopic hepatectomy effectively enhances analgesic outcomes, accelerates postoperative recovery, reduces hospitalization duration, and markedly decreases hospitalization costs.

ABSTRACT

Objective:To investigate the effect of preoperative radiotherapy on postoperative recurrence in central hepatocellular carcinoma patients treated by hepatectomy.Methods:A retrospective cohort study was conducted. Clinicopathological data of 142 patients with central hepatocellular carcinoma who underwent surgical treatment at the Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from January 2016 to January 2019 were retrospectively collected. According to whether they received preoperative radiotherapy or not, the patients were divided into preoperative radiotherapy group (30 cases) and surgery-only group (112 cases). The main observation indexes were recurrence-free survival (RFS), intraoperative bleeding amount, operation time and the occurrence of postoperative complications. Kaplan-Meier method was used for survival analysis, and log-rank test was used for intergroup comparisons; the differences between the two groups for each factor were evaluated by standardized mean difference (SMD); Cox proportional hazards model was used to analyze the influencing factors of RFS in central hepatocellular carcinoma patients with hepatectomy. Propensity score matching (PSM), regression model-adjusted propensity score (CAPS) and inverse probability of treatment weighting (IPTW) methods were used to investigate the relationship between exposure factors and confounding variables and RFS. Sensitivity analysis was performed using E-value to assess the potential impact of unmeasured confounders on outcomes.Results:Men comprised 96.7% (29/30) and 87.5% (98/112) of the preoperative radiotherapy and surgery-only groups, with ages of (55±10) years old and (54±12) years old, respectively. Before matching by the PSM method, there were differences in gender, proportion of patients with hepatitis C, alanine aminotransferase, serum albumin, alpha-fetoprotein, satellite nodules by postoperative pathology, and number of tumors between the two groups (all SMD > 0.1). A total of 26 pairs of patients were successfully matched, and there was no difference in baseline characteristics between the preoperative radiotherapy group and the surgery-only group after matching (all SMD < 0.1). Univariate Cox regression analysis showed that preoperative radiotherapy, number of tumors, maximum diameter of tumor, and satellite nodules by postoperative pathology were the influencing factors of RFS (all P < 0.05); multivariate Cox regression analysis showed that preoperative radiotherapy was an independent protective factor of RFS in central hepatocellular carcinoma patients with hepatectomy ( HR = 0.55, 95% CI: 0.31-0.97, P = 0.038), and maximum diameter of tumor ( HR = 1.08, 95% CI: 1.02-1.15, P = 0.005) and satellite nodules by postoperative pathology ( HR = 1.97, 95% CI: 1.21-3.19, P = 0.006) were independent risk factors of RFS. Preoperative radiotherapy was associated with superior RFS in patients with central hepatocellular carcinoma (PSM, HR = 0.41, 95% CI: 0.20-0.86, P = 0.018; CAPS, HR = 0.42, 95% CI: 0.20-0.87, P = 0.019; IPTW, HR = 0.41, 95% CI: 0.22-0.76, P = 0.005). Before matching, the 1-, 3-, and 5-year postoperative RFS rates in the preoperative radiotherapy group were 77%, 56% and 45%, respectively, and the surgery-only group were 48%, 32% and 28%, respectively. RFS in the preoperative radiotherapy group was superior to that in the surgery-only group before and after matching ( χ2 = 5.65, P = 0.017; χ2 = 6.00, P = 0.014). The E-value for unmeasured confounders altering the conclusions was 2.39, suggesting reliable and stable results. After matching, intraoperative bleeding [ M ( Q1, Q3)] for patients in the preoperative radiotherapy group and the surgery-only group was 300 ml (125 ml, 600 ml) and 400 ml (200 ml, 600 ml), respectively ( U = 0.51, P = 0.611), and the proportions of patients with the operation time >180 min were 92.3% (24/26) and 84.6% (22/ 26), respectively ( χ2 = 0.75, P = 0.385), and the rates of mild postoperative complications were 100.0% (26/26) and 92.3% (24/26), respectively ( χ2 = 2.08, P = 0.149), the differences were not statistically significant. Conclusions:Preoperative radiotherapy for hepatectomy in patients with central hepatocellular carcinoma is safe and effective, and has the advantage of reducing postoperative recurrence.

ABSTRACT

ObjectiveTo investigate the value of continuous monitoring of indocyanine green retention rate at 15 minutes (ICG-R15) combined with standard residual liver volume (SRLV) in predicting hepatic insufficiency after partial hepatectomy. MethodsClinical data and SRLV data were collected from 70 patients with hepatocellular carcinoma who were admitted to Department of Hepatobiliary Surgery, Tianjin First Central Hospital, from November 2016 to May 2017. According to the presence or absence of hepatic insufficiency after surgery, the patients were divided into good liver function group with 56 patients and hepatic insufficiency group with 14 patients. Based on preoperative liver function evaluation and contrast-enhanced CT scans, resected liver volume and residual liver volume were calculated, and three-dimensional reconstruction of the liver was performed. Intraoperative ultrasound localization was performed to determine the surgical regimen, and selective hepatic inflow occlusion or intermittent hepatic portal occlusion was selected based on intraoperative conditions. CUSA combined with BIPOLAR drip electric coagulation forceps were used for the partition of liver parenchyma. SRLV was calculated, and ICG-R15 was monitored continuously. The independent-samples t test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; the area under the ROC curve (AUC) was used to investigate the accuracy in predicting hepatic insufficiency after surgery. A multivariate Logistic regression analysis was used to establish a predictive model for postoperative hepatic insufficiency, and diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency. ResultsThere were significant differences between the two groups in ICG-R15 before surgery, immediately after surgery, and on days 3 and 5 after surgery, as well as significant differences in SRLV and Child class (all P<0.05). The incidence rate of postoperative hepatic insufficiency increased with the increase in ICG-R15 before surgery, immediately after surgery, and on days 3 and 5 after surgery (all P<0.001). Further comparison between two groups showed that there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15>20% group and the other two groups before surgery, immediately after surgery, and on days 3 and 5 after surgery (all P<0.001), and there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15<10% group and the 10%≤ICG-R15≤20% group immediately after surgery (P<0.001). ICG-R15 before surgery, ICG-R15 immediately after surgery, ICG-R15 on day 3 after surgery, and ICG-R15 on day 5 after surgery had an AUC of 0.790, 0.857, 0.855, and 0.870, respectively, in predicting postoperative hepatic insufficiency, and ICG-R15 immediately after surgery and on days 3 and 5 after surgery had a significantly larger AUC than ICG-R15 before surgery (all P<0.05). The multivariate analysis showed that increases in SRLV and postoperative ICG-R15 dynamic monitoring (immediately after surgery and on days 3 and 5 after surgery) were independent risk factors for postoperative hepatic insufficiency, while increased body mass index before surgery was an independent protective factor (all P<0.05). A multivariate Logistic regression predictive model was established and was used to predict hepatic insufficiency after surgery (immediately after surgery and on days 3 and 5 after surgery), and the ROC curve analysis showed that the model had an AUC of 0.963, 0.967, and 0.967, respectively, in predicting hepatic insufficiency immediately after surgery and on days 3 and 5 after surgery (all P<0.01). Diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency, i.e., SLRV>1 240 mL/m2, ICG-R15>20% immediately after surgery, or ICG-R15>25% on day 3 or 5 after surgery, and postoperative hepatic insufficiency could be diagnosed if a patient met any one criterion. These diagnostic criteria had a sensitivity of 100%, a specificity of 60.71%, and a conformity degree of 68.57%. ConclusionContinuous monitoring of ICG-R15 before and after surgery is of guiding significance for predicting postoperative hepatic insufficiency, and ICG-R15 on day 5 after surgery has the highest accuracy. SRLV combined with postoperative ICG-R15 dynamic monitoring can effectively predict the onset of hepatic insufficiency after hepatectomy and can guide clinicians to predict the onset of postoperative hepatic insufficiency in patients with liver cancer and perform clinical intervention as soon as possible.

ABSTRACT

Lograr determinar el volumen total de un hígado (VHT), o volumetría hepática, pasa a ser de relevancia en diversas situaciones, tales como, vigilancia del progreso de una enfermedad de carácter crónico, planificación de resecciones y trasplantes hepáticos; y observación del clearance hepático de algunos fármacos hepatotropos. La VHT se puede realizar utilizando métodos de segmentación en el curso de una tomografía computarizada (TC), ya sean estos manual, automáticos, y semiautomáticos; mediante resonancia nuclear (RN), utilizando softwares de distintas generaciones (1ª a 4ª). La medición de VHT está indicada en pacientes sometidos a resecciones hepáticas mayores, en el contexto del tratamiento de neoplasias (carcinoma hepatocelular, colangiocarcinoma, metástasis hepáticas o tumores benignos de gran tamaño), abscesos (piogénicos, amebianos), y después de un traumatismo hepático complejo; así como también en la etapa preoperatoria de un trasplante hepático. El objetivo de este manuscrito fue generar un documento de estudio sobre métodos para determinar volumetría hepática.


SUMMARY: Being able to determine the total hepatic volume (THV), or THV, becomes relevant in various situations, such as monitoring the progress of a chronic disease, planning resections and liver transplants; and observation of the hepatic clearance of some hepatotropic drugs. THV can be performed using segmentation methods in the course of a computed tomography (CT), whether manual, automatic, or semi-automated; by nuclear resonance (NR), using software from different generations (1st to 4st). THV measurement is indicated in patients undergoing major liver resections, in the context of treatment of neoplasms (hepatocellular carcinoma, cholangiocarcinoma, liver metastases or large benign tumors), abscesses (pyogenic, amoebic), and after liver trauma complex, as well as in the preoperative stage of a liver transplant. The aim of this manuscript was to generate a study document regarding methods for determine hepatic volumetry.

ABSTRACT

Introducción. La neoplasia colorrectal es una patología oncológica muy frecuente a nivel mundial y una de las causas más comunes de mortalidad por cáncer. La epidemiologia, diagnóstico y tratamiento han sido ampliamente estudiadas, mientras que los datos sobre la enfermedad metastásica siguen siendo escasos. El hígado es el órgano más comúnmente afectado y algunos estudios sugieren diferencias en sobrevida y resecabilidad según la localización del tumor primario. El objetivo de este estudio fue establecer el comportamiento y resecabilidad de neoplasias avanzadas colorrectales en dos hospitales de la ciudad de Medellín, Colombia. Métodos. Estudio analítico retrospectivo para identificar los patrones de las metástasis hepáticas y sus características en función de las diferencias clínicas, histológicas y endoscópicas del tumor colorrectal primario entre 2015 y 2020. Resultados. Se recolectaron 54 pacientes con neoplasia colorrectal y metástasis hepáticas, 21 (39 %) derechas y 33 (61 %) izquierdas. El número de metástasis promedio fue de 3,1 en tumores del lado derecho y de 2,4 del izquierdo y el tamaño promedio de cada lesión fue de 4,9 y 4,2 cm, respectivamente. La tasa de resecabilidad fue del 42 % en los tumores derechos y del 82 % en los izquierdos. Las lesiones metacrónicas presentaron una tasa de resecabilidad del 90 % y las sincrónicas del 61 %. Conclusión. En este estudio, las lesiones originadas en neoplasias primarias del colon izquierdo y las lesiones metacrónicas fueron factores pronósticos favorables para la resecabilidad, un factor que impacta en la sobrevida y el tiempo libre de enfermedad de estos pacientes.


Introduction. Colorectal tumor is the most frequent pathology worldwide and one of the most common causes of mortality attributed to cancer. Epidemiology, diagnosis and treatment have been extensively studied, while information on metastatic disease remains scarce, despite being the main cause of death. Some studies suggest differences in terms of survival and resectability according to the anatomical location of the primary tumor. The aim is to establish the behavior and resectability of advanced cancers in two high-complex hospitals in the city of Medellín, Colombia. Methods. Cross-sectional observational study from secondary sources of information based on a retrospective cohort, using available data from adult patients with colorectal cancer and liver metastases between 2015 and 2020. Results. Fifty-four patients with colorectal neoplasms and liver metastases were collected, of which 21 (39%) were on the right side. The average number of liver metastases was 3.1 on the right side and 2.4 on the left, and the average size of each metastatic lesion was 4.9 cm and 4.2 cm, respectively. The resectability rate was 42% in the right tumors and 82% in the left ones. Metachronous lesions had a resectability rate of 90% and synchronous ones 61%. Conclusion. The complete resectability of liver metastatic lesions is the only therapeutic alternative with impact, in terms of survival and disease-free time in these patients. The favorable prognostic factors for the resectability of these lesions in our study were those originating from left primary tumors and metachronous lesions, where less liver tumor involvement was evidenced

ABSTRACT

RESUMEN Antecedentes : las ventajas de la hepatectomía videolaparoscópica (HVL) hicieron que gane cada vez más campo para el tratamiento de los tumores hepáticos benignos (THB). Objetivo : comparar los resultados perioperatorios de pacientes sometidos a HVL con los de los operados con hepatectomía abierta (HA) por THB, emparejados con propensity score matching (PSM). Material y métodos : estudio descriptivo, retrospectivo y comparativo de HA y HVL por THB entre agosto de 2010 y junio de 2021. Se analizaron variables demográficas, preoperatorias, intraoperatorias y posoperatorias. Para evitar sesgos de las distintas covariables entre los grupos se realizó un PSM 1:1. Resultados : de 403 hepatectomías, se analizaron 82 por THB. De ellas 36 (44%) fueron HA y 46 (56%) HVL. Edad media 45 ±14 años, 65% mujeres. Tras realizar el PSM, quedaron dos grupos de 28 pacientes cada uno. En HA, 5 (18%) pacientes requirieron transfusiones y ninguno en HVL (p = 0,01). Las complicaciones mayores se presentaron en 4 (14%) pacientes en HA, y ninguna en HVL (p = 0,03). Se reoperaron 4 (14%) pacientes con HA y ningún paciente con HVL (p = 0,03). La estadía hospitalaria total fue significativamente mayor en las HA (p = 0,04). No se registraron muertes a los 90 días en ninguno de los dos grupos. Conclusión : la HVL por THB es una técnica segura y eficaz, ya que los pacientes presentaron menor requerimiento transfusional, número de reoperaciones, de complicaciones mayores y de estadía hospitalaria que con HA. Por las ventajas encontradas, la HVL podría ser considerada la técnica de elección en cirugía por THB.


ABSTRACT Background : The advantages of laparoscopic liver resection (LLR) have increased its use for the treatment of benign liver tumors (BLTs). Objective : The aim of this study was to compare the perioperative outcomes of patients undergoing LLR with those operated on with open liver resection (OLR) for BLTs using propensity score matching (PSM). Material and methods : We conducted a descriptive and retrospective study comparing OLRs with LLRs performed between August 2010 and June 2021. The demographic, perioperative, intraoperative and postoperative variables were analyzed. We used PSM with 1:1 matching to avoid biases of the different covariates between the groups. Results : Of 303 liver resections, 82 corresponded to BLTs and were included in the analysis; 36 (44%) were OLRs and 46 (56%) were LLRs. Mean age was 45 ±14 years and 65% were women. After PSM, two groups of 28 patients each were constituted. Five patients (18%) in the OLR group and none in the LLR required transfusions (p = 0.01). Major complications, occurred in 4 (14%) patients in the OLR group and in no cases in the LLR group (p = 0.03). Four (14%) undergoing OLR required reoperation versus no patients with LLR (p = 0.03). Total length of hospital stay was significantly longer in OLR (p = 0.04). There were no deaths in any of the groups within 90 days. Conclusion : LLR for BLTs is a safe and effective technique, with lower requirement for transfusions, fewer reoperations and major complications and shorter length of hospital stay than OLR, Therefore, LLR could be considered the surgical technique of choice for BLTs.

ABSTRACT

Introducción. Las neoplasias quísticas mucinosas del hígado son tumores poco frecuentes, equivalen a menos del 5 % de todas las lesiones quísticas hepáticas y se originan generalmente en la vía biliar intrahepática, con poco compromiso extrahepático. En la mayoría de los casos su diagnóstico es incidental dado que es una entidad generalmente asintomática con un curso benigno; sin embargo, hasta en el 30 % pueden ser malignas. En todos los casos se debe hacer una resección quirúrgica completa de la lesión. Caso clínico. Se presentan dos pacientes con diagnóstico de neoplasia quística mucinosa en la vía biliar intrahepática, así como sus manifestaciones clínicas, hallazgos imagenológicos y tratamiento. Discusión. Debido a su baja incidencia, esta patología constituye un reto diagnóstico, que se puede confundir con otro tipo de entidades más comunes. El diagnóstico definitivo se hace de forma histopatológica, pero en todos los casos, ante la sospecha clínica, se recomienda la resección completa. Conclusión. Se presentan dos pacientes con diagnóstico de neoplasias quísticas mucinosas del hígado, una entidad poco frecuente y de difícil diagnóstico


Introduction. Mucinous cystic neoplasms of the liver are rare tumors, accounting for less than 5% of all liver cystic lesions, and generally originate from the intrahepatic bile duct with little extrahepatic involvement. In most cases its diagnosis is incidental since it is a generally asymptomatic entity with a benign course; however, up to 30% can have a malignant course. In all cases, complete surgical resection of the lesion must be performed. Clinical case. Two patients with a diagnosis of mucinous cystic neoplasm in the intrahepatic bile duct are presented, as well as their clinical manifestations, imaging findings, and treatment. Discussion. Due to its low incidence, this pathology constitutes a diagnostic challenge, which can be confused with other types of more common entities. The definitive diagnosis is made histopathologically, but in all cases, given clinical suspicion, complete resection is recommended. Conclusion. Two patients with a diagnosis of mucinous cystic neoplasms of the liver are presented, a rare entity that is difficult to diagnose
