RESUMO
BACKGROUND: Although previous studies have noted the potential benefit of early drain removal (EDR) after pancreatoduodenectomy (PD), there is a paucity of data on the timing of drain removal utilizing a national database that reflect the "real world" setting. Given the ongoing controversy related to PD drain use and management, we sought to define trends in drain use among a large national cohort, as well as identify factors associated with EDR following PD. METHODS: The ACS NSQIP targeted pancreatectomy database was used to identify patients who underwent PD between 2014 and 2020. The trend in proportion of patients with EDR (removal ≤ POD3) as well as predictors of EDR were assessed. Risk-adjusted postoperative outcomes were evaluated by multivariable regression analysis. RESULTS: Among 14,356 patients, 16.2% of patients (N = 2324) experienced EDR, and the proportion of patients with EDR increased by 68% over the study period (2014: 10.9% vs. 2020: 18.3%, p < 0.001). Higher drain fluid amylase on POD1-3 [LogWorth (LW) = 44.3], operative time (LW = 33.2), and use of minimally invasive surgery (LW = 14.0) were associated with EDR. Additionally, EDR was associated with decreased risk of overall and serious morbidity, PD-related morbidity (e.g., pancreatic fistula), reoperation, prolonged length of stay and readmission (all p < 0.05). CONCLUSIONS: Routine drain placement remains a common practice among most surgeons. EDR following PD increased over time was associated with lower post-operative complications and shorter LOS. Despite evidence that EDR was safe and may even be associated with lower complications, only 1 in 6 patients were managed with EDR.

PURPOSE: The World Health Organization recommends prophylactic negative pressure wound therapy (NPWT) for high-risk SSI wounds, despite which delayed wound healing (DWH) remains a problem. The aim of this study was to define the risk factors for DWH under prophylactic NPWT following colorectal perforation (CP). METHODS: The subjects of this retrospective study were patients who underwent emergency laparotomy and prophylactic NPWT for CP between 2011 and 2019 at Fujisawa City Hospital in Japan. Multivariable analysis was performed to identify which perioperative factors impact DWH. RESULTS: A total of 58 patients met the inclusion criteria and the median period from surgery to wound closure was 12 days (IQR: 8-18). Most factors, including preoperative steroid use, diabetes, and serum albumin, were not associated with DWH, although patients requiring catecholamine were more likely to have DWH (OR 7.81, 95% CI 1.55-39.24, p = 0.013). The median in-hospital cost was more than double for patients with DWH vs. those without DWH (41.36 kUSD [IQR 24.95-51.89] vs. 20.32 kUSD [IQR 16.69-28.45], p < 0.001). CONCLUSION: Catecholamine use was a greater risk factor for DWH than previously reported factors such as diabetes and the serum albumin level. Further study is needed to investigate strategies to prevent DWH and optimize the utilization of NPWT, especially in patients requiring catecholamine.

Laparoscopic and endoscopic cooperative surgery(LECS)for gastric gastrointestinal stromal tumor(GIST)has become a popular surgery with both curability and functional preservation. In this study, we examined the outcomes of 14 patients who underwent classical LECS or CLEAN-NET in our hospital. Until March 2022, classical LECS was performed in patients with intraluminal growth tumors or tumors close to the gastroesophageal junction. After April 2022, classical LECS was performed in patients with intraluminal growth tumors without ulceration, and CLEAN-NET was performed in patients with ulceration or intramural growth tumors. There were 10 males and 4 females with a median age of 80.5 years. Intraluminal growth tumor were 8 patients, close to the gastroesophageal junction tumor were 3, and intramural growth tumor were 4, respectively. Five of these patients had tumors with ulceration. Classical LECS was performed in 10 patients and CLEAN-NET in 4 patients, and the median operative time was 165.5 minutes. All patients underwent R0 resection, and no postoperative complications or recurrences were observed. LECS was performed safely, and it is important to select the surgical procedure according to the tumor site and growth type.

We report a case of a patient with locally recurrent esophageal cancer after chemoradiation therapy(CRT)who responded to nivolumab. The patient was an 86-year-old man with advanced esophageal cancer. Upper gastrointestinal endoscopy (EGD)revealed a type 2 lesion in the middle thoracic esophagus, and biopsy revealed squamous cell carcinoma(SCC). Contrast- enhanced CT showed invasion of the left main bronchi. The patient was diagnosed as Stage â £a advanced esophageal cancer, and was treated with 5-FU plus cisplatin chemotherapy, and 60 Gy of radiation therapy. The tumor disappeared by CT and EGD, and the patient was followed up for observation. The patient experienced a feeling of tightness again, and EGD revealed an ulcerative lesion in the middle thoracic esophagus, and a biopsy detected SCC. Because of the early recurrence after CRT, the patient was judged to be resistant to 5-FU plus cisplatin chemotherapy, and 8 courses of nivolumab were administered as second-line treatment. Follow-up EGD confirmed disappearance of ulcerative lesions, and no tumors have been observed to date.

A 77-year-old man presented to our hospital with diarrhea and weight loss. Upper gastrointestinal endoscopy revealed advanced Type 3 gastric cancer measuring 40 mm in the lower greater curvature of the stomach. Biopsy from a gastric tumor revealed moderately differentiated tubular adenocarcinoma overexpressing HER2. Abdominal contrast-enhanced computed tomography(CT)showed multiple liver metastases in S3 and S5. We diagnosed HER2-positive gastric cancer with liver metastasis. Systemic chemotherapy was administrated, with a total of 13 courses of combination therapy with S-1, oxaliplatin and trastuzumab. After chemotherapy, the primary tumor was significantly reduced and liver metastases were almost undetectable. Laparoscopic distal gastrectomy and partial hepatectomy were performed as conversion surgery. The patient was discharged on the 9th day without any postoperative complications. Postoperative pathological findings showed no residual tumor in either gastric and hepatic specimens, and the therapeutic effect of chemotherapy was diagnosed as pathological complete response. We report a case of HER2-positive advanced gastric cancer with multiple liver metastases that achieved a pathologically complete response to chemotherapy followed by conversion surgery. Laparoscopic surgery would be one of an effective option for conversion surgery.

BACKGROUND: We sought to define the association of the systemic immune inflammation index (SII) with prognosis and adjuvant therapy benefit among patients undergoing resection of extrahepatic cholangiocarcinoma (eCCA). METHODS: The impact of SII on overall (OS) and recurrence-free survival (RFS) following resection of eCCA was assessed and compared with other inflammatory markers and traditional prognostic factors. Propensity score matching (PSM) was used to determine the impact of adjuvant therapy (AT) on OS and RFS relative to low versus high SII. RESULTS: Patients with high versus low SII had worse 5-year OS (15.9% vs. 27.9%) and RFS (12.4% vs. 20.9%) (both p < 0.01). On multivariate analysis, high SII remained associated with worse OS (HR = 1.50, 95% CI 1.20-1.87) and RFS (HR = 1.46, 95% CI 1.18-1.81). Patients with T1/2 disease and a high-SII had worse 5-year OS versus individuals with T3/4 disease and low-SII (5-year OS: T1/2 & low-SII 35.6%, T1/2 & high-SII 16.4%, T3/4 & low-SII 22.1%, T3/4 & high-SII 15.6%, p < 0.01). Similarly, 5-year OS was comparable among individuals with N0 and high-SII versus N1 and low-SII (5-year OS: N0 & high-SII 23.2%, N1 and low-SII 19.8%, p = 0.95). On PSM, AT improved OS and RFS among patients with high SII (5-year OS: 22.5% vs. 12.3%, p < 0.01, 5-year RFS: 19.0% vs. 12.5%; p = 0.01) but not individuals with low SII (5-year OS: 22.9% vs. 26.9%; p = 0.98, 5-year RFS: 18.5% vs. 19.9%; p = 0.94). CONCLUSIONS: SII was independently associated with postoperative OS and RFS following curative-intent resection of eCCA. High SII up-staged patients relative T- and N-categories and identified patients with high SII as the most likely to benefit from AT.

BACKGROUND: Estimation of mortality risk traditionally has only included preoperative factors. We sought to develop "real-time" mortality risk-calculator for patients who undergo pancreatoduodenectomy (PD) based on preoperative factors, as well as events that occurred during the course of patient's surgery and hospitalization. METHODS: Patients who underwent PD from 2014 to 2018 were identified in the ACS-NSQIP dataset. Training and validation cohorts were created. Pre-, intra-, and post-operative models to predict 30-day mortality were developed based on perioperative variables selected by stepwise cox regression analyses; model performance was assessed using AUC. RESULTS: Among 17,683 patients who underwent PD, 1.6% died within 30-days. Patient factors and events associated with 30-day mortality were incorporated into a risk calculator (https://ktsahara.shinyapps.io/Real-timePD/). The accuracy of the risk-calculator increased relative to hospital time-course in both the training (AUC, pre-:0.696, intra-:0.724, post-operative:0.871) and validation (AUC, pre-:0.681, intra-:0.702, post-operative:0.850) cohorts. One in 3 patients had a concordant calculated risk of mortality using pre-versus postoperative variables to inform the risk model (kappa = 0.474). CONCLUSION: Risk of mortality fluctuated over the hospital course following PD and preoperative risk assessment was often discordant with risk assessed at other periods. The proposed "real-time" calculator may help better stratify patients with increased risk of 30-day mortality.

BACKGROUND: Although multidisciplinary treatments including the use of adjuvant therapy (AT) have been adopted for biliary tract cancers, patients with distal cholangiocarcinoma (DCC) can still experience recurrence. We sought to characterize the incidence and predictors of early recurrence (ER) that occurred within 12 months following surgery for DCC. PATIENTS AND METHODS: Patients who underwent resection for DCC between 2000 and 2015 were identified from the US multi-institutional database. Cox regression analysis was used to identify clinicopathological factors to develop an ER risk score, and the predictive model was validated in an external dataset. RESULTS: Among 245 patients included in the analysis, 67 patients (27.3%) developed ER. No difference was noted in ER rates between patients who did and did not receive AT (28.7% vs. 25.0%, p = 0.55). Multivariable analysis revealed that neutrophil-to-lymphocyte ratio (NLR), peak total bilirubin (T-Bil), major vascular resection (MVR), lymphovascular invasion, and R1 surgical margin status were associated with a higher ER risk. A DIstal Cholangiocarcinoma Early Recurrence Score was developed according to each factor available prior to surgery [NLR > 9.0 (2 points); peak T-bil > 1.5 mg/dL (1 points); MVR (2 points)]. Cumulative ER rates incrementally increased among patients who were low (0 points; 10.6%), intermediate (1-2 points; 26.8%), or high (3-5 points; 57.6%) risk (p < 0.001) in the training dataset, as well as in the validation dataset [low (0 points); 3.4%, intermediate (1-2 points); 32.7%, or high risk (3-5 points); 55.6% (p < 0.001)]. CONCLUSIONS: Among patients undergoing resection for DCC, 1 in 4 patients experienced an ER. Alternative treatment strategies such as neoadjuvant chemotherapy may be considered especially among individuals deemed to be at high risk for ER.

BACKGROUND: The optimal time interval to define early recurrence (ER) among patients who underwent resection of gallbladder cancer (GBC) is not well defined. We sought to develop and validate a novel GBC recurrence risk (GBRR) score to predict ER among patients undergoing resection for GBC. PATIENTS AND METHODS: Patients who underwent curative-intent resection for GBC between 2000 and 2018 were identified from the US Extrahepatic Biliary Malignancy Consortium database. A minimum p value approach in the log-rank test was used to define the optimal cutoff for ER. A risk stratification model was developed to predict ER based on relevant clinicopathological factors and was externally validated. RESULTS: Among 309 patients, 103 patients (33.3%) had a recurrence at a median follow-up period of 15.1 months. The optimal cutoff for ER was defined at 12 months (p = 3.04 × 10-18). On multivariable analysis, T3/T4 disease (HR: 2.80; 95% CI 1.58-5.11) and poor tumor differentiation (HR: 1.91; 95% CI 1.11-3.25) were associated with greater hazards of ER. The GBRR score was developed using ß-coefficients of variables in the final model, and patients were classified into three distinct groups relative to the risk for ER (12-month RFS; low risk: 88.4%, intermediate risk: 77.9%, high risk: 37.0%, p < 0.001). The external validation demonstrated good model generalizability with good calibration (n = 102: 12-month RFS; low risk: 94.2%, intermediate risk: 59.8%, high risk: 42.0%, p < 0.001). The GBRR score is available online at https://ktsahara.shinyapps.io/GBC_earlyrec/ . CONCLUSIONS: A novel online calculator was developed to help clinicians predict the probability of ER after curative-intent resection for GBC. The proposed web-based tool may help in the optimization of surveillance intervals and the counselling of patients about their prognosis.

INTRODUCTION: While tumor burden (TB) has been associated with outcomes among patients with hepatocellular carcinoma, the role of overall TB in intrahepatic cholangiocarcinoma (ICC) remains poorly defined. METHODS: Patients undergoing curative-intent resection of ICC between 2000 and 2017 were identified from a multi-institutional database. The impact of TB on overall (OS) and disease-free survival (DFS) was evaluated in the multi-institutional database and validated externally. RESULTS: Among 1101 patients who underwent curative-intent resection of ICC, 624 (56.7%) had low TB, 346 (31.4%) medium TB, and 131 (11.9%) high TB. OS incrementally worsened with higher TB (5-year OS; low TB: 48.3% vs medium TB: 29.8% vs high TB: 17.3%, p < 0.001). Similarly, patients with low TB had better DFS compared with medium and high TB patients (5-year DFS: 38.3% vs 18.7% vs 6.9%, p < 0.001). On multivariable analysis, TB was independently associated with OS (medium TB: HR = 1.40, 95% CI 1.14-1.71; high TB: HR = 1.89, 95% CI 1.46-2.45) and DFS (medium TB, HR = 1.61, 95% CI 1.33-1.96; high TB: HR = 2.03, 95% CI 1.56-2.64). Survival analysis revealed an excellent prognostic discrimination using the TB among the external validation cohort (3-year OS; low TB: 44.8%, medium TB: 29.3%; high TB: 23.3%, p = 0.03; 3-year DFS: low TB: 32.7%, medium TB: 10.7%; high TB: 0%, p < 0.001). While neoadjuvant chemotherapy was not associated with survival across the TB groups, receipt of adjuvant chemotherapy was associated with increased survival among patients with high TB (5-year OS: 24.4% vs 13.4%, p = 0.02). CONCLUSION: Overall TB dictated prognosis among patients with resectable ICC. TB may be used as a tool to help guide post-resection treatment strategies.

BACKGROUND: The adoption of spleen-preserving distal pancreatectomy (SPDP) for malignant disease such as pancreatic neuroendocrine tumors (pNETs) has been controversial. The objective of the current study was to assess the impact of SPDP on outcomes of patients with pNETs. METHODS: Patients undergoing a distal pancreatectomy for pNET between 2002 and 2016 were identified in the US Neuroendocrine Tumor Study Group database. Propensity score matching (PSM) was used to compare short- and long-term outcomes of patients undergoing SPDP versus distal pancreatectomy with splenectomy (DPS). RESULTS: Among 621 patients, 103 patients (16.6%) underwent an SPDP. Patients who underwent SPDP were more likely to have lower BMI (median, 27.5 [IQR 24.0-31.2] vs. 28.7 [IQR 25.7-33.6]; p = 0.005) and have undergone minimally invasive surgery (n = 56, 54.4% vs. n = 185, 35.7%; p < 0.001). After PSM, while the median total number of lymph nodes examined among patients who underwent an SPDP was lower compared with DPS (3 [IQR 1-8] vs. 9 [5-13]; p < 0.001), 5-year overall survival (OS) and recurrence-free survival (RFS) were comparable (OS: 96.8 vs. 92.0%, log-rank p = 0.21, RFS: 91.1 vs. 84.7%, log-rank p = 0.93). In addition, patients undergoing SPDP had less intraoperative blood loss (median, 100 mL [IQR 10-250] vs. 150 mL [IQR 100-400]; p = 0.001), lower incidence of serious complications (n = 13, 12.8% vs. n = 28, 27.5%; p = 0.014), and shorter length of stay (median: 5 days [IQR 4-7] vs. 6 days [IQR 5-13]; p = 0.049) compared with patients undergoing DPS. CONCLUSION: SPDP for pNET was associated with acceptable perioperative and long-term outcomes that were comparable to DPS. SPDP should be considered for patients with pNET.

BACKGROUND: Pancreatectomy is the main curative therapeutic option for pancreatic neuroendocrine tumors (pNETs). Given the indolent behavior of pNETs and the relatively limited lifetime of elderly patients, the impact of primary site surgery (PSS) of pNETs on long-term outcomes among older patients has been a topic of debate. METHODS: Patients aged 70 or older with pNETs were identified in the Surveillance, Epidemiology and the End Results (SEER) database from 1998 to 2016. Propensity score matching was used to compare overall (OS) and cancer-specific survival (CSS) of patients who did versus did not undergo PSS. RESULTS: Among 2,319 elderly patients with pNETs, 942 patients (40.6%) underwent PSS, while 1,377 (59.4%) did not undergo PSS (non-PSS: NPSS). After propensity score matching (n = 433 in each group), PSS group had improved survival compared with the NPSS group (5-year OS: 53.4% vs. 37.3%; 5-year CSS: 77.2% vs. 58.1%, both p < 0.001). In contrast, subgroup analysis of individuals aged ≥ 80 revealed no difference in 5-year CSS (PSS: 69.2% vs. NPSS: 67.4%, p = 0.27). A subgroup analysis among patients who had small (≤ 2 cm) non-functional (NF) pNETs noted comparable long-term outcomes among patients who underwent PSS versus NPSS patients (5-year OS: 73.1% vs. 66.5%, p = 0.19; 5-year CSS: 98.5% vs. 95.2%, p = 0.14). CONCLUSIONS: Approximately 2 in 5 elderly patients with pNETs underwent PSS. While PSS was generally associated with prolonged OS and CSS among older patients, PSS was not associated with improved CSS among a subset of patients aged 80 or older, as well as among patients age ≥ 70 years with NF-pNET less than 2 cm.

PURPOSE: The objective of the current study was to assess the therapeutic benefit of lymphadenectomy according to the extent of lymphadenectomy. METHODS: Patients undergoing colectomy for right-sided colon cancer were identified. Distribution of lymph node metastases (DLNM) of 1, 2 and 3 were defined as lymph node metastasis (LNM) in the pericolic nodes, the intermediate nodes and the front of the SMV near the origin of the major artery, respectively. The therapeutic index (TI) was calculated based on the frequency of LNM and the 5 year overall survival (OS) rate of patients with LNM. RESULTS: Among 344 patients who met the inclusion criteria, roughly half had LNM (n = 150, 43.7%). While 107 (31.1%) and 30 (8.7%) patients had DLNM1 and DLNM2, respectively, only 13 patients (3.8%) were defined as DLNM3. However, there was no significant difference in 5 year OS by DLNM (DLNM1 71.1%, DLNM2 78.7%, DLNM3 50.4%, p = 0.61). Overall, the TI of lymphadenectomy for D3 area was approximately 1/10 of the TI for D1 (1.9 vs.22.1), given the low frequency of LNM (3.8%) and poor 5 year OS of patients with LNM (50.4%). This trend was consistent irrespective of primary tumor locations. CONCLUSION: The survival benefit from central lymphadenectomy namely D3 was low among patients with right-sided colon cancers.

OBJECTIVE: The objective of the current study was to define surgical outcomes after resection of multinodular hepatocellular carcinoma (HCC) beyond the Milan criteria, and develop a prediction tool to identify which patients likely benefit the most from resection. BACKGROUND: Liver resection for multinodular HCC, especially beyond the Milan criteria, remains controversial. Rigorous selection of the best candidates for resection is essential to achieve optimal outcomes after liver resection of advanced tumors. METHODS: Patients who underwent resection for HCC between 2000 and 2017 were identified from an international multi-institutional database. Patients were categorized according to Milan criteria status. Pre- and postoperative overall survival (OS) prediction models that included HCC tumor burden score (TBS) among patients with multinodular HCC beyond Milan criteria were developed and validated. RESULTS: Among 1037 patients who underwent resection for HCC, 164 (15.8%) had multinodular HCC beyond the Milan criteria. Among patients with multinodular HCC, 25 (15.2%) patients experienced a serious complication and 90-day mortality was 3.7% (n = 6). Five-year OS after resection of multinodular HCC beyond Milan criteria was 52.8%. A preoperative TBS-based model (5-year OS: low-risk, 73.7% vs intermediate-risk, 45.1% vs high-risk, 13.1%), and postoperative TBS-based model (5-year OS: low-risk, 80.1% vs intermediate-risk, 37.2% vs high-risk, not reached) categorized patients into distinct prognostic groups relative to long-term prognosis (both P < 0.001). Pre- and postoperative models could accurately stratify OS in an external validation cohort (5-year OS; low vs medium vs high risk; pre: 66.3% vs 25.2% vs not reached, P = 0.012; post: 61.4% vs 42.5% vs not reached, P = 0.045) Predictive accuracy of the pre- and postoperative models was good in the training (c-index; pre: 0.68; post: 0.71), internal validation (n = 2000 resamples) (c-index, pre: 0.70; post: 0.72) and external validation (c-index, pre: 0.67; post 0.68) datasets. TBS alone could stratify patients relative to 5-year OS after resection of multinodular HCC beyond Milan criteria (c-index: 0.65; 5-year OS; low TBS: 70.2% vs medium TBS: 54.7% vs high TBS: 16.7%; P < 0.001). The vast majority of patients with low and intermediate TBS were deemed low or medium risk based on both the preoperative (98.4%) and postoperative risk scores (95.3%). CONCLUSION: Prognosis of patients with multinodular HCC was largely dependent on overall tumor burden. Liver resection should be considered among patients with multinodular HCC beyond the Milan criteria who have a low- or intermediate-TBS.

INTRODUCTION: The aim of the current study is to assess rates of textbook outcome (TO) among Medicare beneficiaries undergoing hepatopancreatic (HP) surgery for cancer at dedicated cancer centers (DCCs) and National Cancer Institute affiliated cancer centers (NCI-CCs) versus non-DCC non-NCI hospitals. PATIENTS AND METHODS: Medicare Inpatient Standard Analytic Files were utilized to identify patients undergoing HP surgery between 2013 and 2017. TO was defined as no postoperative surgical complications, no 90-day mortality, no prolonged length of hospital stay, and no 90-day readmission after discharge. RESULTS: Among 21,234 Medicare patients, 8.2% patients underwent surgery at DCCs whereas 32.1% underwent surgery at NCI-CCs and 59.7% underwent an operation at neither DCCs nor NCI-CCs. Although DCCs more often cared for patients with severe comorbidities [Charlson score > 5: DCCs, 1195 (68.9%), NCI-CCs, 3687 (54.1%), others, 3970 (31.3%); p < 0.001], DCCs achieved higher rates of TO compared with NCI-CCs and other US hospitals. Interestingly, DCCs were more likely to perform surgery with a minimally invasive approach versus NCI-CCs and other US hospitals (17.0%, n = 295, vs. 12.6%, n = 856 vs. 11.9%, n = 1504, p < 0.001). On multivariable analysis, patients undergoing liver surgery at DCCs had 31% and 36% higher odds of achieving TO compared with NCI-CCs and other US hospitals, respectively. Medicare expenditure was substantially lower for patients achieving TO at DCCs compared with patients who achieved a TO at NCI-CCs. CONCLUSIONS: Even though DCCs more frequently took care of patients with high comorbidity burden, the likelihood of achieving TO for HP surgery at DCCs was higher compared with NCI-CCs and other US hospitals. The data suggest that DCCs provide higher-value surgical care for patients with HP malignancies.

BACKGROUND: The Centers for Medicare and Medicaid Services (CMS) Hospital Compare star rating system has been proposed as a means to assess hospital quality performance. The current study aimed to investigate outcomes and payments among patients undergoing surgery for colorectal, lung, esophageal, pancreatic, and liver cancer across hospital star rating groups. METHODS: The Medicare Standard Analytic Files (SAF) from 2013 to 2015 were used to derive the analytic cohort. The association of star ratings to perioperative outcomes and expenditures was examined. RESULTS: Among 119,854 patients, the majority underwent surgery at a 3-star (n = 34,901, 29.1%) or 4-star (n = 30,492, 25.4%) hospital. Only 12.2% (n = 14,732) were treated at a 5-star hospital. Across all procedures examined, patients who underwent surgery at a 1-star hospital had greater odds of death within 90 days than patients who had surgery at a 5-star hospital (colorectal, 1.41 [95% confidence interval {CI}, 1.25-1.60]; lung, 1.97 [95% CI 1.56-2.48]; esophagectomy, 1.83 [95% CI 0.81-4.16]; pancreatectomy, 1.70 [95% CI 1.20-2.41]; hepatectomy, 1.63 [95% CI 0.96-2.77]). A similar trend was noted for failure to rescue (FTR), with the greatest odds of FTR associated with 1-star hospitals. The median expenditure associated with an abdominal operation was $1661 more at a 1-star hospital than at a 5-star hospital (1-star: $17,399 vs 5-star: $15,738). A similar trend was noted for thoracic operations. CONCLUSION: The risk of FTR, 90-day mortality, and increased hospital expenditure were all higher at a 1-star hospital. Further research is needed to investigate barriers to care at 5-star-rated hospitals and to target specific interventions to improve outcomes at 1-star hospitals.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) and portal vein hypertension assessed with platelet count (PVH-PLT; platelet count < 100,000/mL) are often denied surgery even when the disease is technically resectable. Short- and long-term outcomes of patients undergoing minimally invasive surgery (MIS) versus open resection for HCC and PVH-PLT were compared. METHODS: Propensity score matching (PSM) was used to balance the clinicopathological differences between MIS and non-MIS patents. Univariate comparison and standard survival analyses were utilized. RESULTS: Among 1974 patients who underwent surgery for HCC, 13% had a PVH-PLT and 33% underwent MIS. After 1:1 PSM, 407 MIS and 407 non-MIS patients were analyzed. Incidence of complications and length-of-stay (LoS) were higher among non-MIS versus MIS patients (both p ≤ 0.002). After PSM, among 178 PVH-PLT patients (89 MIS and 89 non-MIS), patients who underwent a non-MIS approach had longer LoS (> 7 days; non-MIS: 55% vs. MIS: 29%), as well as higher morbidity (non-MIS: 42% vs. MIS: 29%) [p <0.001]. In contrast, long-term oncological outcomes were comparable, including 3-year overall survival (non-MIS: 66.2% vs. MIS: 72.9%) and disease-free survival (non-MIS: 47.3% vs. MIS: 50.2%) [both p ≥ 0.08]. CONCLUSION: An MIS approach was associated with improved short-term outcomes, but similar long-term outcomes, compared with open liver resection for patients with HCC and PVH-PLT. An MIS approach for liver resection should be considered for patients with HCC, even those individuals with PVH-PLT.

BACKGROUND: Several investigators have advocated for extending the Barcelona Clinic Liver Cancer (BCLC) resection criteria to select patients with BCLC-B and even BCLC-C hepatocellular carcinoma (HCC). The objective of the current study was to define the outcomes and recurrence patterns after resection within and beyond the current resection criteria. PATIENTS AND METHODS: Patients who underwent resection for HCC within (i.e., BCLC 0/A) and beyond (i.e. BCLC B/C) the current resection criteria between 2005 and 2017 were identified from an international multi-institutional database. Overall survival (OS), disease-free survival (DFS), as well as patterns of recurrence of patients undergoing HCC resection within and beyond the BCLC guidelines were examined. RESULTS: Among 756 patients, 602 (79.6%) patients were BCLC 0/A and 154 (20.4%) were BCLC B/C. Recurrences were mostly intrahepatic (within BCLC: 74.3% versus beyond BCLC: 70.8%, p = 0.80), with BCLC B/C patients more often having multiple tumors at relapse (69.6% versus 49.4%, p = 0.001) and higher rates of early (< 2 years) recurrence (88.0% versus 75.5%, p = 0.011). During the first postoperative year, annual recurrence was 38.3% and 21.3% among BCLC B/C and BCLC 0/A patients, respectively; 5-year OS among BCLC 0/A and BCLC B/C patients was 76.9% versus 51.6% (p = 0.003). On multivariable analysis, only a-fetoprotein (AFP) > 400 ng/mL (HR = 1.84, 95% CI 1.07-3.15) and R1 resection (HR = 2.36, 95% CI 1.32-4.23) were associated with higher risk of recurrence among BCLC B/C patients. CONCLUSIONS: Surgery can provide acceptable outcomes among select patients with BCLC B/C HCC. The data emphasize the need to further refine the BCLC treatment algorithm as well as highlight the need for surveillance protocols with a particular focus on the liver, especially for patients undergoing resection outside the BCLC criteria.

RESUMO
INTRODUCTION: The objective of the current study was to comprehensively assess the change of practice in hepatobiliary surgery by determining the rates and the trends of textbook outcomes (TO) among patients undergoing surgery for primary liver cancer over time. METHODS: Patients undergoing curative-intent resection for primary liver malignancies, including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) between 2005 and 2017 were analyzed using a large, international multi-institutional dataset. Rates of TO were assessed over time. Factors associated with achieving a TO and the impact of TO on long-term survival were examined. RESULTS: Among 1829 patients, 944 (51.6%) and 885 (48.4%) individuals underwent curative-intent resection for HCC and ICC, respectively. Over time, patients were older, more frequently had ASA class > 2, albumin-bilirubin grade 2/3, major vascular invasion and more frequently underwent major liver resection (all p < 0.05). Overall, a total of 1126 (62.0%) patients achieved a TO. No increasing trends in TO rates were noted over the years (ptrend = 0.90). In addition, there was no increasing trend in the TO rates among patients undergoing either major (ptrend = 0.39) or minor liver resection (ptrend = 0.63) over the study period. Achieving a TO was independently associated with 26% and 37% decreased hazards of death among ICC (HR 0.74, 95%CI 0.56-0.97) and HCC patients (HR 0.63, 95%CI 0.46-0.85), respectively. CONCLUSION: Approximately 6 in 10 patients undergoing surgery for primary liver tumors achieved a TO. While TO rates did not increase over time, TO was associated with better long-term outcomes following liver resection for both HCC and ICC.
