RESUMEN

Background: The cachexia index (CXI), which consists of skeletal muscle, inflammation, and nutritional status, has been associated with prognosis in patients with hepatocellular carcinoma (HCC). We hypothesized that dynamic changes in CXI might be associated with long-term outcomes in HCC. Methods: This study comprised 131 patients who had undergone primary hepatic resection for HCC between 2008 and 2019. Preoperative CXI (pre-CXI) and postoperative CXI (post-CXI) were calculated by the following formula: skeletal muscle index x serum albumin level / neutrophil-to-lymphocyte ratio. Pre- and post-CXI were classified into two groups (high vs. low). We retrospectively investigated the association of perioperative dynamic changes in CXI with disease-free and overall survival. Results: In multivariate analyses, negative HBs-antigen (p = 0.02), high serum PIVKA-II level (p < 0.01), poor tumor differentiation (p = 0.02), multiple tumors (p < 0.01), microvascular invasion (p < 0.01), partial resection (p < 0.01), postoperative complications (p < 0.01), and low-pre-CXI (p < 0.01) were significant predictors of disease-free survival, while high ICGR15 (p = 0.01), poor tumor differentiation (p < 0.01), multiple tumors (p = 0.01), postoperative complications (p < 0.01), low-pre-CXI (p < 0.01), and low-post-CXI (p < 0.01) were significant predictors of overall survival. Low-post-CXI was associated with older age (p = 0.045), larger tumor (p < 0.01), longer operation time (p = 0.047), greater intraoperative bleeding (p < 0.01), and intraoperative blood transfusion (p < 0.01). Moreover, dynamic changes in CXI were associated with overall survival in each subgroup of patients with low-pre-CXI (p = 0.02) or high-pre-CXI (p = 0.03). Conclusions: Not only post-CXI but also dynamic changes in CXI from pre- to post-hepatectomy can be a prognostic indicator of HCC, providing a compelling rationale for aggressive perioperative nutritional and physical interventions to improve long-term outcomes.

RESUMEN

BACKGROUND: Although the outcomes of living donor liver transplantation (LDLT) for pediatric acute liver failure (PALF) have improved, patient survival remains lower than in patients with chronic liver disease. We investigated whether the poor outcomes of LDLT for PALF persisted in the contemporary transplant era. METHODS: We analyzed 193 patients who underwent LDLT between December 2000 and December 2020. The outcomes of patients managed in 2000-2010 (era 1) and 2011-2020 (era 2) were compared. RESULTS: The median age at the time of LDLT was 1.2 years both eras. An unknown etiology was the major cause in both groups. Patients in era 1 were more likely to have surgical complications, including hepatic artery and biliary complications (p = 0.001 and p = 0.013, respectively). The era had no impact on the infection rate after LDLT (cytomegalovirus, Epstein-Barr virus, and sepsis). The mortality rates of patients and grafts in era one were significantly higher (p = 0.03 and p = 0.047, respectively). The 1- and 5-year survival rates were 76.4% and 70.9%, respectively, in era 1, while they were 88.3% and 81.9% in era 2 (p = 0.042). Rejection was the most common cause of graft loss in both groups. In the multivariate analysis, sepsis during the 30 days after LDLT was independently associated with graft loss (p = 0.002). CONCLUSIONS: The survival of patients with PALF has improved in the contemporary transplant era. The early detection and proper management of rejection in patients, while being cautious of sepsis, should be recommended to improve outcomes further.

RESUMEN

PURPOSE: Abdominal aortic calcification (AAC), an indicator of systemic arteriosclerosis, is associated with short- and long-term outcomes in malignancies. We investigated the prognostic impact of AAC in patients who underwent hepatectomy for intrahepatic cholangiocarcinoma (IHCC). METHODS: The study cohort comprised 46 patients who underwent hepatectomy for IHCC between January 2008 and September 2020. The AAC volume measured by preoperative computed tomography was used to construct a model of the calcified segment from the renal artery to the common iliac artery bifurcation. We investigated the relationship between AAC and the long-term outcomes. The AAC volume cutoff value was calculated from a receiver-operating characteristic curve based on the three-year survival. RESULTS: According to our cutoff AAC volume of 3,700 mm3, 11 patients (24%) had high AAC volumes. The high-AAC group was significantly older than the low-AAC group (73 vs. 62 years old, p < 0.01). A multivariate analysis of the cancer-specific survival showed that a high serum carbohydrate antigen 19-9 concentration (hazard ratio [HR] 5.57, p = 0.01), high AAC volume (HR 3.03, p = 0.04), and [high?] T3 or T4 levels (HR 9.05, p < 0.01) were independently associated with a poor prognosis. CONCLUSION: AAC is a useful predictor of the oncological prognosis in patients undergoing hepatectomy for IHCC.

RESUMEN

BACKGROUND: This study aimed to identify postoperative recurrence and prognostic factors, including osteosarcopenia for borderline resectable (BR) and unresectable locally advanced (UR-LA) pancreatic cancer and to examine the impact of postoperative pancreatic enzyme replacement therapy (PERT). METHODS: We retrospectively examined 32 resected patients with BR and UR-LA pancreatic cancer. We investigated independent factors in the disease-free survival and overall survival. The relation of osteosarcopenia with the clinicopathological factors was investigated. Additionally, the association of the administration of a standard dose of pancrelipase, the amount of lipase required for patients with pancreatic exocrine insufficiency, for ≥6 months postoperatively with improvement of sarcopenia, osteopenia, and osteosarcopenia and completion rate of adjuvant chemotherapy was investigated. RESULTS: Multivariate analyses identified osteosarcopenia (P = 0.049) and lymph node metastasis (P = 0.01) as independent recurrence predictors, and osteosarcopenia (P = 0.002), maximum tumor diameter ≥40 mm (P = 0.006), and no adjuvant therapy (P = 0.01) as independent prognostic predictors. In the osteosarcopenia group, serum CA19-9 levels were higher (P = 0.03). The administration of a standard dose of pancrelipase for ≥6 months postoperatively was none in the osteosarcopenia group (0% vs 42.9%, P = 0.01), while significantly improved postoperative sarcopenia (33% vs 0%, P = 0.004), increased number of cycles of adjuvant chemotherapy (n = 6 vs n = 3, P = 0.03), and the completion rate of adjuvant chemotherapy in excluding cases interrupted because of recurrence (86% vs 25%, P = 0.007). CONCLUSIONS: Osteosarcopenia was an independent recurrent and prognostic factor in patients after pancreatectomy for locally advanced pancreatic cancer. Appropriate postoperative PERT may contribute to a better prognosis by improving sarcopenia and increasing the completion rate of adjuvant chemotherapy.

RESUMEN

BACKGROUND/AIM: The study aimed to investigate the efficacy of radiotherapy or chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer. PATIENTS AND METHODS: Twenty-eight patients who had isolated locoregional recurrence after pancreatectomy for pancreatic cancer between 2007 and 2021 were retrospectively analyzed. We investigated the effect of the treatment method [radiotherapy or chemoradiotherapy (radiotherapy with concurrent chemotherapy)] on progression-free survival (PFS) and post-recurrence survival (PRS). RESULTS: The median disease-free survival was 16.1 months (range=4.7-47.1 months). Five patients received radiotherapy and 21 patients received chemoradiotherapy [radiotherapy concurrent with gemcitabine (GEM) or S-1] for locoregional recurrence. All patients except one patient with interstitial pneumonia were treated with salvage chemotherapy after irradiation. The median PFS rates of the radiotherapy group and the chemoradiotherapy group were 2.8 months (range=1.5-5.4 months) and 16.8 months (range=2.7-42.8 months), respectively. The median PRS rates were 23.7 months (range=8.1-26.4 months) for the radiotherapy group and 26.2 months (range=6.0-64.7 months) for the chemoradiotherapy group. Multivariate analysis identified radiotherapy [hazard ratio (HR)=12.2, 95% confidence interval (CI)=3.29-45.6, p<0.001] and serum DUPAN-2 >150 U/ml (HR=2.90, 95%CI=1.22-6.93, p=0.02) as independent predictors of PFS, and UICC TNM Stage ≥III (HR=3.23, 95%CI=1.17-8.96, p=0.02) and modified Glasgow prognostic score before the treatment for the recurrence 1 or 2 (HR=3.05, 95%CI=1.15-8.08, p=0.03) as independent predictors of PRS. CONCLUSION: Chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer could suppress re-recurrence more effectively than radiotherapy.

RESUMEN

BACKGROUND/AIM: No studies have investigated the advantage of laparoscopic hepatectomy (LH) compared with open hepatectomy (OH) from a nutritional perspective. This study aimed to compare the postoperative nutritional status between LH and OH. PATIENTS AND METHODS: A total of 186 patients who underwent partial hepatic resection for liver tumors were analyzed retrospectively. We compared perioperative variables between LH and OH. The nutritional status was assessed using serum albumin (Alb) and rapid turnover protein concentrations. We investigated risk factors for postoperative malnutrition using univariate and multivariate analyses. RESULTS: The LH group, compared with the OH group, had a significantly shorter operative time (239 vs. 344 min, p<0.03), less intraoperative blood loss (100 vs. 343 g, p<0.01), and a shorter length of postoperative stay (8 vs. 11 days, p<0.01). Postoperative serum Alb and prealbumin concentrations in the LH group were significantly higher than those in the OH group (3.4 vs. 3.2 g/dl, p<0.01; 15.0 vs. 12.0 mg/dl, p=0.02, respectively). The multivariate analysis showed that OH (p=0.02) and hepatocellular carcinoma (p<0.01) were significant and independent risk factors for postoperative malnutrition. CONCLUSION: LH may be superior to OH in terms of the postoperative nutritional status, intraoperative blood loss, and length of postoperative stay.

RESUMEN

BACKGROUND: This study aimed to investigate the effects of changes in clinicopathological factors during preoperative chemotherapy for pancreatic cancer, including skeletal muscle volume, on recurrence and prognosis after pancreatectomy. METHODS: Data from 41 patients who underwent resection for pancreatic cancer after preoperative chemotherapy from 2012 to 2021 were retrospectively reviewed. Skeletal muscle volume was substituted for the psoas muscle area (PMA) at the level of the third lumbar vertebra. We investigated the relationship of clinicopathological factors during preoperative chemotherapy with disease-free survival (DFS) and overall survival (OS). The association between clinicopathological factors and a decrease in PMA was investigated. RESULTS: In the multivariate analyses for DFS and OS, the factors associated with recurrence were as follows: decrease in PMA (P = 0.003) and the absence of adjuvant therapy (P = 0.03), and the factors associated with poor prognosis were as follows: decrease in PMA (P = 0.04) and the absence of adjuvant therapy (P = 0.008), and the resectability of borderline resectable and unresectable-locally advanced tumors (P = 0.033). All patients with partial response according to the Response Evaluation Criteria in Solid Tumors (version 1.1) had no decrease in PMA (P = 0.01). The proportion of patients with Evans classification ≥ II was significantly higher in the group without a decrease in PMA (P = 0.02). The proportion of patients with an average relative dose intensity of adjuvant therapy ≥0.6 was significantly higher in the group without a decrease in PMA (P = 0.02). CONCLUSION: Changes in preoperative skeletal muscle volume during preoperative chemotherapy for pancreatic cancer is a potential predictor of recurrence and prognosis after pancreatectomy.

RESUMEN

BACKGROUND: Despite early diagnosis and medical interventions, patients with methylmalonic acidemia (MMA) suffer from multi-organ damage and recurrent metabolic decompensations. METHODS: We conducted the largest retrospective multi-center cohort study so far, involving five transplant centers (NCCHD, KUH, KUHP, ATAK, and EMC), and identified all MMA patients (n = 38) undergoing LDLT in the past two decades. Our primary outcome was patient survival, and secondary outcomes included death-censored graft survival and posttransplant complications. RESULTS: The overall 10-year patient survival and death-censored graft survival rates were 92% and 97%, respectively. Patients who underwent LDLT within 2 years of MMA onset showed significantly higher 10-year patient survival compared to those with an interval more than 2 years (100% vs. 81%, p = 0.038), although the death-censored graft survival were not statistically different (100% vs. 93%, p = 0.22). Over the long-term follow-up, 14 patients (37%) experienced intellectual disability, while two patients developed neurological complications, three patients experienced renal dysfunction, and one patient had biliary anastomotic stricture. The MMA level significantly decreased from 2218.5 mmol/L preoperative to 307.5 mmol/L postoperative (p = 0.038). CONCLUSIONS: LDLT achieves favorable long-term patient and graft survival outcomes for MMA patients. While not resulting in complete cure, our findings support the consideration of early LDLT within 2 years of disease onset. This approach holds the potential to mitigate recurrent metabolic decompensations, and preserve the long-term renal function.

RESUMEN

Background: This study aimed to identify the prognostic factors after pancreatectomy for borderline resectable pancreatic cancer abutting major arteries (BR-A).Methods: We retrospectively investigated relationship between preoperative and intraoperative variables and overall survival (OS) through univariate and multivariate analyses. The cut-off points of preoperative therapy duration and response rates of serum carbohydrate antigen 19-9 (CA19-9) levels after preoperative therapy were determined through a minimum P-value approach using the log-rank test for OS. Overall survival was compared among patients stratified according to the independent prognostic factors and the presence or absence of pancreatectomy.Results: After pretreatment, 17 patients underwent pancreatectomy and four patients continued chemotherapy without surgery. Multivariate analysis in 17 resected BR-A patients demonstrated decreased serum CA19-9 levels and preoperative therapy duration of ≥4 months were the independent prognostic factors [hazard ratio (HR) 0.01; P = 0.002, HR 0.13; P = 0.02]. Patients who underwent surgery with decreased serum CA19-9 levels after preoperative therapy of ≥4 months had a significantly better prognosis than those without one or both of independent prognostic factors and those who did not undergo surgery (median survival time: not estimated, 23.3 months, 10.5 months, and 10.8 months; P = 0.02, P = 0.004, and P = 0.001, respectively). Furthermore, the prognosis did not significantly differ between the patients who underwent surgery without meeting either one or both criteria and those without surgery.Conclusions: Preoperative therapy duration of ≥4 months and decreased serum CA19-9 levels are independent prognostic factors among BR-A patients.

RESUMEN

BACKGROUND/AIM: This study evaluated the prognostic impact of vertebral fractures (VFs) on the survival of patients with colorectal cancer (CRC). PATIENTS AND METHODS: We included 299 patients with stage I-III CRC who had undergone elective surgery. The patients were divided into the VF group (n=94) and non-VF group (n=205). VFs were assessed using sagittal computed tomography image reconstruction (Th11-L5) performed preoperatively. Disease-free survival (DFS) and overall survival (OS) rates were analyzed. RESULTS: The VF group had lower 5-year DFS and OS rates compared to the non-VF group (both, p<0.001). The independent predictors of DFS were carbohydrate antigen 19-9 (CA19-9) ≥37.0 ng/ml, T3/T4 disease, stage III CRC, osteopenia, and VF; for OS, CA19-9 ≥37.0 ng/ml, stage III, osteopenia, and VF. VF, compared with osteopenia, was a more significant prognostic factor for DFS and OS in patients with stage I+ II CRC (both, p<0.001). CONCLUSION: Preoperative VF was associated with worse DFS and OS following CRC resection.

RESUMEN

PURPOSE: Atherosclerosis and cancer may progress through common pathological factors. This study was performed to investigate the association between the abdominal aortic calcification (AAC) volume and outcomes following surgical treatment for pancreatic cancer. METHODS: The subjects of this retrospective study were 194 patients who underwent pancreatic cancer surgery between 2007 and 2020. The AAC volume was assessed through routine preoperative computed tomography. Univariate and multivariate analyses were performed to evaluate the impact of the AAC volume on oncological outcomes. RESULTS: A higher AAC volume (≥ 312 mm3) was identified in 66 (34%) patients, who were significantly older and had a higher prevalence of diabetes and sarcopenia. Univariate analysis revealed several risk factors for overall survival (OS), including male sex, an AAC volume ≥ 312 mm3, elevated carbohydrate antigen 19-9, prolonged operation time, increased intraoperative bleeding, lymph node metastasis, poor differentiation, and absence of adjuvant chemotherapy. Multivariate analysis identified an AAC volume ≥ 312 mm3, prolonged operation time, lymph node metastasis, poor differentiation, and absence of adjuvant chemotherapy as independent OS risk factors. The OS rate was significantly lower in the high AAC group than in the low AAC group. CONCLUSION: The AAC volume may serve as a preoperative prognostic indicator for patients with pancreatic cancer.

RESUMEN

Decreasing the graft size in living donor liver transplantation (LDLT) increases the risk of early allograft dysfunction. Graft-to-recipient weight ratio (GRWR) of 0.8 is considered the threshold. There is evidence that smaller volume grafts may also provide equally good outcomes, the cut-off of which remains unknown. In this retrospective multicenter study, 92 adult LDLTs with a final GRWR ≤0.6 performed at 12 international liver transplant centers over a 3-year period were included. Perioperative data including preoperative status, portal flow hemodynamics (PFH) and portal flow modulation, development of small for size syndrome (SFSS), morbidity, and mortality was collated and analyzed. Thirty-two (36.7%) patients developed SFSS and this was associated with increased 30-day, 90-day, and 1-year mortality. The preoperative model for end-stage liver disease and inpatient status were independent predictors for SFSS (P < .05). Pre-liver transplant renal dysfunction was an independent predictor of survival (hazard ratio 3.1; 95% confidence intervals 1.1, 8.9, P = .035). PFH or portal flow modulation were not predictive of SFSS or survival. We report the largest ever multicenter study of LDLT outcomes using ultralow GRWR grafts and for the first time validate the International Liver Transplantation Society-International Living donor liver transplantation study group-Liver Transplantation Society of India consensus definition and grading of SFSS. Preoperative recipient condition rather than GRWR and PFH were independent predictors of SFSS. Algorithms to predict SFSS and LT outcomes should incorporate recipient factors along with GRWR.

RESUMEN

Liver transplantation is often the only lifesaving option for acute liver failure (ALF); however, the predictors of short-term mortality (death within one year) after living donor liver transplantation (LDLT) for ALF have yet to be defined. We retrospectively collected patients ≥18 years old who underwent LDLT for ALF between 2010 and 2020 at 35 centers in Asia. Univariate and multivariate logistic regression analyses were conducted to identify the clinical variables related to short-term mortality and establish a novel scoring system. The Kaplan-Meier method was performed to explore the association between the score and overall survival. Of the 339 recipients, 46 (13.6%) died within 1 year after LDLT. Multivariate analyses revealed 4 independent risk factors for death: use of vasopressors or mechanical ventilation, the higher model for end-stage liver disease score, and a lower graft-to-recipient weight ratio. The internally validated c-statistic of the short-term mortality after transplant (SMT) score derived from these 4 variables was 0.80 (95% confidence interval: 0.74-0.87). The SMT score successfully stratified recipients into low-, intermediate-, and high-risk groups with 1-year overall survival rates of 96%, 80%, and 50%, respectively. In conclusion, our novel SMT score based on 4 predictors will guide ALF recipient and living donor selection.

RESUMEN

BACKGROUND/AIM: With the aging of the population, there is a rising proportion of elderly patients undergoing liver resection. However, the safety and efficacy of laparoscopic liver resection (LLR) in the elderly have not yet been established. In this study, we compared the short-term results of LLR and open liver resection (OLR) in elderly patients using propensity score matched (PSM) analysis. PATIENTS AND METHODS: The study comprised 237 elderly patients aged 65 years and older who had undergone liver resection between 2015 to 2021, excluding biliary and vascular reconstruction and simultaneous surgeries other than liver resection. We conducted PSM analysis for baseline characteristics (age, sex, BMI, ASA-PS, disease, procedure, tumor size, and number of tumors) to eliminate potential selection bias. We then compared short-term postoperative outcomes between LLR and OLR groups in patients selected by PSM analysis. RESULTS: Applying PSM analysis, 90 cases each were selected for the LLR and OLR groups. The LLR group had a significantly lower complication rate (Clavien-Dindo: CD ≥II) (19% vs. 33%, p=0.03), especially bile leakage (CD ≥II) (0% vs. 6.7%, p=0.03) compared with those in the OLR group. In addition, a shorter operation time (244 min vs. 351 min, p<0.01), less blood loss (150 ml vs. 335 ml, p<0.01), and shorter hospital stay (8 days vs. 12 days, p<0.01) were observed in the LLR group. No operative or in-hospital deaths were observed in both groups. CONCLUSION: LLR can be safely performed in elderly patients and offers better short-term outcomes.

RESUMEN

BACKGROUND: We investigated the prognostic impact of osteosarcopenia, defined as the combination of osteopenia and sarcopenia, in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma (PDAC). METHODS: The relationship of osteosarcopenia with disease-free survival and overall survival was analyzed in 183 patients who underwent elective pancreatic resection for PDAC. Computed tomography was used to measure the pixel density in the midvertebral core of the 11th thoracic vertebra for evaluation of osteopenia and in the psoas muscle area of the 3rd lumbar vertebra for evaluation of sarcopenia. Osteosarcopenia was defined as the simultaneous presence of both osteopenia and sarcopenia. The study employed a retrospective design to examine the relationship between osteosarcopenia and survival outcomes. RESULTS: Osteosarcopenia was identified in 61 (33%) patients. In the univariate analysis, disease-free survival was significantly worse in patients with male sex (p = 0.031), pathological stage ≥ III PDAC (p = 0.001), NLR, ≥ 2.71 (p = 0.041), sarcopenia (p = 0.027), osteopenia (p = 0.001), and osteosarcopenia (p < 0.001), and overall survival was significantly worse in patients with male sex (p = 0.001), pathological stage ≥ III PDAC (p = 0.001), distal pancreatectomy (p = 0.025), sarcopenia (p = 0.003), osteopenia (p < 0.001), and osteosarcopenia (p < 0.001). In the multivariate analysis, the independent predictors of disease-free survival were osteosarcopenia (p < 0.001) and pathological stage ≥ III PDAC (p = 0.002), and the independent predictors of overall survival were osteosarcopenia (p < 0.001), male sex (p = 0.006) and pathological stage ≥ III PDAC (p = 0.001). CONCLUSION: Osteosarcopenia has an adverse prognostic impact on long-term outcomes in patients undergoing pancreatic resection for PDAC.

RESUMEN

BACKGROUND: The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index is a novel immune nutrition scoring system associated with cancer prognosis. This study investigated the association between the CALLY index and the long-term outcomes of patients with gastric cancer. METHODS: We included 175 patients with gastric cancer who underwent curative gastrectomies at the Department of Surgery, International University of Health and Welfare Hospital between January 2011 and October 2019. The CALLY index was calculated based on the levels of serum albumin, serum CRP, and peripheral lymphocyte count. Utilizing both univariate and multivariate analyses, the prognostic value of the CALLY index was investigated. RESULTS: In the multivariate analyses, disease stage (hazard ratio [HR], 7.85; 95% confidence interval [CI], 3.31-18.6; P < .01), microvascular invasion (HR, 2.88; 95% CI, 1.30-6.36; P < .01), and low CALLY index (HR, 2.18; 95% CI, 1.00-4.76; P = .05) were independent and significant predictors of disease-free survival. Low body mass index (HR, 4.15; 95% CI, 1.63-10.6; P < .01), advanced disease stage (HR, 8.22; 95% CI, 3.47-19.5; P < .01), and low CALLY index (HR, 3.00; 95% CI, 1.3-6.93; P = .01) were independent and significant predictors of overall survival. The low CALLY index group had a lower body mass index (P < .01), advanced disease stage (P < .01), and a higher Glasgow prognostic score (P < .01). CONCLUSIONS: The CALLY index may be associated with a poor prognosis for gastric cancer, highlighting the utility of a comprehensive assessment using inflammatory, nutritional, and immunological statuses.

RESUMEN

PURPOSE: Simultaneous dual hepatic vein embolization (DHVE) has been proposed for safe right-sided hepatectomy, with good results for liver hypertrophy and function. However, the histological and radiological findings of DHVE have not been thoroughly investigated. METHODS: This study included 14 patients who underwent DHVE before right-sided major hepatectomy. DHVE was performed if the future liver remnant was < 35% or borderline, but with concomitant vascular resection. The liver function was assessed using the signal intensity on Gd-EOB-DTPA-MRI. A histological evaluation of the area of DHVE and portal vein embolization (PVE) were performed. RESULTS: The median pre- and post-functional liver remnants were 363 ml and 498 ml, respectively (p < 0.001). The median growth rate was 48.6%, and there was no post-hepatectomy liver failure in the patients who underwent DHVE. The signal intensity ratio in the area of DHVE was lower than that in the areas of PVE and the remnant liver (p < 0.01). The degree of congestion and necrosis was greater in the area of DHVE than in the area of PVE alone (p < 0.01 and p = 0.04, respectively). CONCLUSIONS: We observed good liver hypertrophy after DHVE and histological and radiological changes in the area of DHVE. Our findings provide a compelling rationale for further investigation of the mechanism of liver hypertrophy in DHVE.

RESUMEN

BACKGROUND/AIM: Laparoscopic hepatic resection is currently used for ruptured hepatocellular carcinoma (HCC); however, it is technically challenging. We developed and implemented surgical strategies for emergency laparoscopic partial liver resection in selected patients with peripheral lesions who were hemodynamically stable and without severe liver dysfunction. PATIENTS AND METHODS: The surgical techniques used were as follows. First, the Pringle maneuver was performed to control hepatic blood inflow (step 1). Next, strong hemostatic agents were applied at the rupture point of the tumor (step 2). The hanging tape was positioned along the dorsal side of the resection line to control the partial blood inflow and outflow of the tumor, as well as to expose the surgical plane (step 3). The liver parenchyma was dissected along the hanging tape (step 4). We performed emergency laparoscopic partial liver resection in three patients who were in a pre-shock status. RESULTS: The tumors were located in segments 6 (cases 1 and 2) and 2 (case 3). The tumor diameters were 90, 62, and 80 mm. The Preoperative Child-Pugh scores were B7, B9, and B8. The hemostatic products performed well and controlled bleeding from the ruptured HCC. The hanging tape facilitated the dissection of the liver parenchyma. The operative time and intraoperative blood loss were 135 min and 400 ml, 266 min and 200 ml, and 191 min and 495 ml for cases 1, 2, and 3 respectively. There were no in-hospital deaths. CONCLUSION: Emergency laparoscopic partial liver resection could be an option for patients with ruptured HCC.

RESUMEN

BACKGROUND/AIM: This study aimed to identify the risk factors for early recurrence (ER) after pancreatic ductal adenocarcinoma (PDAC) resection to create a novel scoring system for ER and analyze their effect on the recurrence pattern. PATIENTS AND METHODS: Sixty patients with PDAC who underwent pancreatectomy were included. The predicted risk factors for ER were analyzed. A new score defining ER was created and analyzed for recurrence pattern and prognosis. RESULTS: Independent predictors included high CA 19-9 (≥147 U/ml), high lymph node ratio (LNR of ≥0.1277), and no adjuvant chemotherapy (AC). The 5-year overall survival rates with a score of 0, 1, and 2 were 55.8%, 11.0%, and 0%, respectively. In the moderate- risk score group, prognosis was improved by induction of AC within 58 days. CONCLUSION: Preoperative high CA19-9, high LNR, and no AC could be ER predictors. Induction of postoperative chemotherapy within 58 days may improve prognosis.
