Treatment adherence and wellness, nutrition, and physical activity outcomes of diabetic patients with comorbid depression during the 18-month follow-up of the TELE-DD study.

BACKGROUND: A good adherence to pharmacological treatment in chronic pathologies such as type 2 diabetes and clinical depression is essential to improve illness prognosis. AIMS: The main goal of the TELE-DD study was to analyze the effectiveness of a telephone, psychoeducational, and individualized intervention carried out by nurses in patients with type 2 diabetes mellitus and comorbid clinical depression with prior nonadherence to pharmacological treatment. In this paper, we describe and analyze secondary outcomes of the trial intervention. METHODS: A prospective cohort study was used to assess the effectiveness of a telephonic intervention (IG) in n = 191 participants with a similar control group (CG). Adherence to pharmacological treatment was assessed using the patient's self-perceived adherence questionnaire. In addition to clinical (HbAc1, HDL, LDL), physical (body mass index, blood pressure) and psychological measures (Patient Health Questionnaire-9 affective state), and psychosocial distress due to Diabetes Distress Scale Questionnaire at 3, 6, 12, and 18 months of follow-up were also analyzed. RESULTS: The proportion of "Total Adherents" in the IG was higher throughout the study. This was particularly true at month 18 of the intervention. Self-perceived adherence rates increased by 27.1% in the IG and by 1.1% in the CG. Results of clinical and physical measures were higher in the IG than in the CG at month 18 of the intervention. LINKING EVIDENCE TO ACTION: The interview based on positive reinforcement as well as individualized attention and flexibility in making telephone calls and dissemination of the intervention in the media closest to the patients were key to achieving good participation and collaboration as well as continuity in adherence to treatment and self-care.

Therapeutic drug monitoring of neoadjuvant mFOLFIRINOX in resected pancreatic ductal adenocarcinoma.

BACKGROUND: Despite a potentially curative treatment, the prognosis after upfront surgery and adjuvant chemotherapy for patients with resectable pancreatic ductal adenocarcinoma (PDAC) is poor. Modified FOLFIRINOX (mFOLFIRINOX) is a cornerstone in the systemic treatment of PDAC, including the neoadjuvant setting. Pharmacokinetic-guided (PKG) dosing has demonstrated beneficial effects in other tumors, but scarce data is available in pancreatic cancer. METHODS: Forty-six patients with resected PDAC after mFOLFIRINOX neoadjuvant approach and included in an institutional protocol for anticancer drug monitoring were retrospectively analyzed. 5-Fluorouracil (5-FU) dosage was adjusted throughout neoadjuvant treatment according to pharmacokinetic parameters and Irinotecan (CPT-11) pharmacokinetic variables were retrospectively estimated. RESULTS: By exploratory univariate analyses, a significantly longer progression-free survival was observed for patients with either 5-FU area under the curve (AUC) above 28 mcg·h/mL or CPT-11 AUC values below 10 mcg·h/mL. In the multivariate analyses adjusted by age, gender, performance status and resectability after stratification according to both pharmacokinetic parameters, the risk of progression was significantly reduced in patients with 5-FU AUC ≥28 mcg·h/mL [HR = 0.251, 95% CI 0.096-0.656; p = 0.005] and CPT-11 AUC <10 mcg·h/mL [HR = 0.189, 95% CI 0.073-0.486, p = 0.001]. CONCLUSIONS: Pharmacokinetically-guided dose adjustment of standard chemotherapy treatments might improve survival outcomes in patients with pancreatic ductal adenocarcinoma.

Effects of eHealth interventions on stress reduction and mental health promotion in healthcare professionals: A systematic review.

AIMS: To evaluate the effectiveness of eHealth interventions to reduce stress and promote mental health in healthcare professionals, and to compare the efficacy of different types of programs (guided vs. self-guided; 'third-wave' psychotherapies vs. other types). BACKGROUND: Healthcare workers present high levels of stress, which constitutes a risk factor for developing mental health problems such as depression and anxiety. eHealth interventions have been designed to reduce these professional's stress considering that the characteristics of this delivery method make it a cost-effective and very appealing alternative because of its fast and easy access. DESIGN: A systematic review of quantitative studies. METHODS: A comprehensive database search for quantitative studies was conducted in PubMed, EMBASE and Cochrane (until 1 April 2022). The systematic review was conducted in accordance with the PRISMA and SWiM reporting guidelines. The quality of the studies was assessed using the National Heart, Lung and Blood Institute tools. RESULTS: The abstracts of 6349 articles were assessed and 60 underwent in-depth review, with 27 fulfilling the inclusion criteria. The interventions were classified according to their format (self-guided vs. guided) and contents ('third-wave' psychotherapies vs. others). Twenty-two interventions emerged, 13 of which produced significant posttreatment reductions in stress levels of health professionals (9 self-guided, 8 'third wave' psychotherapies). Significant effects in improving depressive symptomatology, anxiety, burnout, resilience and mindfulness, amongst others, were also found. CONCLUSION: The evidence gathered in this review highlights the heterogeneity of the eHealth interventions that have been studied; self-guided and 'third-wave' psychotherapy programs are the most common, often with promising results, although the methodological shortcomings of most studies hinder the extraction of sound conclusions.

Delays to surgery following chemoradiotherapy lead to poorer oncologic outcomes in patients with localized pancreatic adenocarcinoma.

BACKGROUND: although neoadjuvant chemoradiotherapy (NCRT) and surgery are accepted as treatments for pancreatic ductal adenocarcinoma (PDAC), some authors have highlighted the risks of delaying surgery. The objective of this study was to analyze the impact of prolonging the time interval between NCRT and surgery (NCRT-TTS) in PDAC. METHODS: patients treated with NCRT and pancreatoduodenectomy (PD) were identified. Clinical, histopathological variables were analyzed about whether NCRT-TTS was greater or less than 50 days. Five- and ten-year overall survival (OS) and disease-free survival (DFS) were analyzed depending on whether the delay was greater than 50 days or not. RESULTS: one hundred (8.3 %) of 120 eligible patients underwent PD (61 male, median age of 63.7 years). In 71 (71 %) patients, the median NCRT-TTS was 39 (24-50) days and in 29 (29 %) 61 days. There were no differences between the two groups except for carbohydrate antigen 19-9 (CA 19-9) levels, the incidence of cholangitis, American Society of Anesthesiologists (ASA) score, intraoperative blood transfusions and degree of histopathologic response (all p < 0.001). Median DFS when the NCRT-TTS was less than 50 days was higher than when the interval exceeded 50 days (51.0 months [95 % CI: 20.3-81.6] vs 17.0 months [95 %: CI 10.9-23.0]; HR [95 % CI 1.08-3.46], p = 0.026). Five-year DFS was higher in the subgroup with NCRT-TTS of less than 50 days compared to the group with an interval of more than 50 days (43.5 % vs 23.65 % [HR 1.812, 95 % CI: 1.001-3.280], p = 0.050). CONCLUSIONS: an increase in the NCRT-TTS > 50 days is associated with poorer OS and DFS in patients with localized PDAC treated with NCRT and PD.

Minimally Invasive Donor Hepatectomy for Adult Living Donor Liver Transplantation: An International, Multi-institutional Evaluation of Safety, Efficacy and Early Outcomes.

OBJECTIVE: Evaluating the perioperative outcomes of minimally invasive (MIV) donor hepatectomy for adult live donor liver transplants in a large multi-institutional series from both Eastern and Western centers. BACKGROUND: Laparoscopic liver resection has become standard practice for minor resections in selected patients in whom it provides reduced postoperative morbidity and faster rehabilitation. Laparoscopic approaches in living donor hepatectomy for transplantation, however, remain controversial because of safety concerns. Following the recommendation of the Jury of the Morioka consensus conference to address this, a retrospective study was designed to assess the early postoperative outcomes after laparoscopic donor hepatectomy. The collective experience of 10 mature transplant teams from Eastern and Western countries was reviewed. METHODS: All centers provided data from prospectively maintained databases. Only left and right hepatectomies performed using a MIV technique were included in this study. Primary outcome was the occurrence of complications using the Clavien-Dindo graded classification and the Comprehensive Complication Index during the first 3 months. Logistic regression analysis was used to identify risk factors for complications. RESULTS: In all, 412 MIV donor hepatectomies were recorded including 164 left and 248 right hepatectomies. Surgical technique was either pure laparoscopy in 175 cases or hybrid approach in 237. Conversion into standard laparotomy was necessary in 17 donors (4.1%). None of the donors died. Also, 108 experienced 121 complications including 9.4% of severe (Clavien-Dindo 3-4) complications. Median Comprehensive Complication Index was 5.2. CONCLUSIONS: This study shows favorable early postoperative outcomes in more than 400 MIV donor hepatectomy from 10 experienced centers. These results are comparable to those of benchmarking series of open standard donor hepatectomy.

Pure laparoscopic major liver resection after yttrium90 radioembolization: a case-matched series analysis of feasibility and outcomes.

BACKGROUND: Liver surgery after radioembolization (RE) entails highly demanding and challenging procedures due to the frequent combination of large tumors, severe RE-related adhesions, and the necessity of conducting major hepatectomies. Laparoscopic liver resection (LLR) and its associated advantages could provide benefits, as yet unreported, to these patients. The current study evaluated feasibility, morbidity, mortality, and survival outcomes for major laparoscopic liver resection after radioembolization. MATERIAL AND METHODS: In this retrospective, single-center study patients diagnosed with hepatocellular carcinoma, intrahepatic cholangiocarcinoma or metastases from colorectal cancer undergoing major laparoscopic hepatectomy after RE were identified from institutional databases. They were matched (1:2) on several pre-operative characteristics to a group of patients that underwent major LLR for the same malignancies during the same period but without previous RE. RESULTS: From March 2011 to November 2020, 9 patients underwent a major LLR after RE. No differences were observed in intraoperative blood loss (50 vs. 150 ml; p = 0.621), operative time (478 vs. 407 min; p = 0.135) or pedicle clamping time (90.5 vs 74 min; p = 0.133) between the post-RE LLR and the matched group. Similarly, no differences were observed on hospital stay (median 3 vs. 4 days; p = 0.300), Clavien-Dindo ≥ III complications (2 vs. 1 cases; p = 0.250), specific liver morbidity (1 vs. 1 case p = 1.000), or 90 day mortality (0 vs. 0; p = 1.000). CONCLUSION: The laparoscopic approach for post radioembolization patients may be a feasible and safe procedure with excellent surgical and oncological outcomes and meets the current standards for laparoscopic liver resections. Further studies with larger series are needed to confirm the results herein presented.

Comparison of phenotypes and outcomes following resection of incidental versus symptomatic pancreatic neuroendocrine tumors.

BACKGROUND AND AIM: fifty to 70 percent of pancreatic neuroendocrine tumors are diagnosed incidentally. The objective of this study was to compare the phenotype and oncological outcomes of incidental versus symptomatic pancreatic neuroendocrine tumors. METHODS: a retrospective study was performed, identifying all incidental and symptomatic tumors resected between 2000 and 2019. Baseline characteristics, symptoms, operative variables and pathological stage were all recorded. Patterns of recurrence and overall and disease-free survival were analyzed in both groups. RESULTS: fifty-one incidental and 45 symptomatic pancreatic tumor resections were performed. Symptomatic tumors were more frequent in females (29 vs 17; p = 0.005) and younger patients (median years; 50 vs 58; p = 0.012) and were detected at a more advanced stage (p = 0.027). There were no differences in location and most resections (n = 49; 51 %) were performed laparoscopically. There were no operative mortalities and 17 (17.7 %) severe complications (≥ IIIb on the Clavien-Dindo classification) were recorded with no differences between the two groups. With a median follow-up of 64.4 months (range 13.5-90), overall survival at five and ten years was 89.7 % and 72.8 % for the non-incidental tumors and 80.9 % and 54.6 % for the incidental tumors (p = ns), respectively. Disease-free survival in both groups (excluding M1a) was 71.2 % and 47.5 %, and 93.7 % and 78.1 %, respectively (p = ns). CONCLUSIONS: symptomatic tumors are more frequent in females and present at more advanced pathological stages. There were no significant differences in overall and disease-free survival between the two groups. Resection of incidental tumors ≥ 1.5-2 cm seems advisable, although each case should be assessed on an individual basis.

Effects of everolimus plus minimized tacrolimus on kidney function in liver transplantation: REDUCE, a prospective, randomized controlled study.

BACKGROUND AND AIM: reduction in calcineurin inhibitor levels is considered crucial to decrease the incidence of kidney dysfunction in liver transplant (LT) recipients. The aim of this study was to evaluate the safety and impact of everolimus plus reduced tacrolimus (EVR + rTAC) vs. mycophenolate mofetil plus tacrolimus (MMF + TAC) on kidney function in LT recipients from Spain. METHODS: the REDUCE study was a 52-week, multicenter, randomized, controlled, open-label, phase 3b study in de novo LT recipients. Eligible patients were randomized (1:1) 28 days post-transplantation to receive EVR + rTAC (TAC levels ≤ 5 ng/mL) or to continue with MMF + TAC (TAC levels = 6-10 ng/mL). Mean estimated glomerular filtration rate (eGFR), clinical benefit in renal function, and safety were evaluated. RESULTS: in the EVR + rTAC group (n = 105), eGFR increased from randomization to week 52 (82.2 [28.5] mL/min/1.73 m2 to 86.1 [27.9] mL/min/1.73 m2) whereas it decreased in the MMF + TAC (n = 106) group (88.4 [34.3] mL/min/1.73 m2 to 83.2 [25.2] mL/min/1.73 m2), with significant (p < 0.05) differences in eGFR throughout the study. However, both groups had a similar clinical benefit regarding renal function (improvement in 18.6 % vs. 19.1 %, and stabilization in 81.4 % vs. 80.9 % of patients in the EVR + rTAC vs. MMF + TAC groups, respectively). There were no significant differences in the incidence of acute rejection (5.7 % vs. 3.8 %), deaths (5.7 % vs. 2.8 %), and serious adverse events (51.9 % vs. 44.0 %) between the 2 groups. CONCLUSION: EVR + rTAC allows a safe reduction in tacrolimus exposure in de novo liver transplant recipients, with a significant improvement in eGFR but without significant differences in renal clinical benefit 1 year after liver transplantation.

Preoperative hepatic artery embolization before distal pancreatectomy plus celiac axis resection does not improve surgical results: A Spanish multicentre study.

BACKGROUND: Distal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate. OBJECTIVE: comparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE. METHODS: Observational retrospective multicentre study. INCLUSION CRITERIA: patient operated in Spanish centers with DP-CAR for pancreatic cancer from April 2004 until 23 June 2018. Preoperative (PHAE, neodjuvant treatment), intraoperative (operative time and blood loss) and postoperative data (morbidity, hospital stay, R0 and survival) were studied. Complications were measured with Clavien classification at 90 days. Specific pancreatic complications were measured using ISGPS classifications. Data were analyzed using R version 3.1.3 (http://www.r-project.org). Level of significance was set at 0.05. RESULTS: 41 patients were studied. 26 patients were not embolized (NO-PHAE group) and 15 patients received PHAE. Preoperative BMI and percentage of neoadjuvant chemotherapy were the only preoperative variables different between both groups. The operative time in the PHAE group was shorter (343 min) than in the non-PHAE group (411 min) (p < 0.06). Major morbidity (Clavien > IIIa) and mortality at 90 days were higher in the PHAE group than in the non-PHAE group (60% vs 23% and 26.6% vs 11.6% respectively) (p < 0.004). No statistical difference in overall survival was observed between both groups (p = 0.14). CONCLUSION: In our study PHAE is not related with less postoperative morbidity. Even more, major morbidity (Clavien III-IV) and mortality was higher in PHAE group.

Incidental lesions of the pancreas. A clinicopathological study of 100 cases surgically treated.

OBJECTIVE: the objective of the present study was to analyze the characteristics of resected incidental lesions of the pancreas. MATERIAL AND METHODS: a retrospective study was performed of pancreatectomies due to incidentalomas between 1995 and 2018. RESULTS: one hundred pancreatectomies were performed due to incidental lesions; 64 (64%) were solid and 36 (36%) were cystic lesions. The cytological analysis agreed with the diagnosis in 67/71 (88.7%) cases. Thirty-six tumors were cystic, 48 were neuroendocrine and 16 were adenocarcinomas. Disease-free survival for patients with cystic, neuroendocrine tumors and adenocarcinomas was 100%, 79% and 57.7% (p < 0.04). CONCLUSION: pancreatic incidentalomas have a heterogeneous phenotype and should be treated in experienced centers.

Normothermic regional perfusion vs. super-rapid recovery in controlled donation after circulatory death liver transplantation.

BACKGROUND & AIMS: Although there is increasing interest in its use, definitive evidence demonstrating a benefit for postmortem normothermic regional perfusion (NRP) in controlled donation after circulatory death (cDCD) liver transplantation is lacking. The aim of this study was to compare results of cDCD liver transplants performed with postmortem NRP vs. super-rapid recovery (SRR), the current standard for cDCD. METHODS: This was an observational cohort study including all cDCD liver transplants performed in Spain between June 2012 and December 2016, with follow-up ending in December 2017. Each donor hospital determined whether organ recovery was performed using NRP or SRR. The propensity scores technique based on the inverse probability of treatment weighting (IPTW) was used to balance covariates across study groups; logistic and Cox regression models were used for binary and time-to-event outcomes. RESULTS: During the study period, there were 95 cDCD liver transplants performed with postmortem NRP and 117 with SRR. The median donor age was 56 years (interquartile range 45-65 years). After IPTW analysis, baseline covariates were balanced, with all absolute standardised differences <0.15. IPTW-adjusted risks were significantly improved among NRP livers for overall biliary complications (odds ratio 0.14; 95% CI 0.06-0.35, p <0.001), ischaemic type biliary lesions (odds ratio 0.11; 95% CI 0.02-0.57; p = 0.008), and graft loss (hazard ratio 0.39; 95% CI 0.20-0.78; p = 0.008). CONCLUSIONS: The use of postmortem NRP in cDCD liver transplantation appears to reduce postoperative biliary complications, ischaemic type biliary lesions and graft loss, and allows for the transplantation of livers even from cDCD donors of advanced age. LAY SUMMARY: This is a propensity-matched nationwide observational cohort study performed using livers recovered from donors undergoing cardiac arrest provoked by the intentional withdrawal of life support (controlled donation after circulatory death, cDCD). Approximately half of the livers were recovered after a period of postmortem in situ normothermic regional perfusion, which restored warm oxygenated blood to the abdominal organs, whereas the remainder were recovered after rapid preservation with a cold solution. The study results suggest that the use of postmortem normothermic regional perfusion helps reduce rates of post-transplant biliary complications and graft loss and allows for the successful transplantation of livers from older cDCD donors.

A 4K-Input High-Speed Winner-Take-All (WTA) Circuit with Single-Winner Selection for Change-Driven Vision Sensors.

Winner-Take-All (WTA) circuits play an important role in applications where a single element must be selected according to its relevance. They have been successfully applied in neural networks and vision sensors. These applications usually require a large number of inputs for the WTA circuit, especially for vision applications where thousands to millions of pixels may compete to be selected. WTA circuits usually exhibit poor response-time scaling with the number of competitors, and most of the current WTA implementations are designed to work with less than 100 inputs. Another problem related to the large number of inputs is the difficulty to select just one winner, since many competitors may have differences below the WTA resolution. In this paper, a WTA circuit is presented that handles more than four thousand inputs, to our best knowledge the hitherto largest WTA, with response times below the microsecond, and with a guaranty of just a single winner selection. This performance is obtained by the combination of a standard analog WTA circuit and a fast digital single-winner selector with almost no size penalty. This WTA circuit has been successfully employed in the fabrication of a Selective Change-Driven Vision Sensor based on 180 nm CMOS technology. Both simulated and experimental results are presented in the paper, showing that a single pixel event can be selected in just 560 ns, and a multipixel pixel event can be processed in 100 us. Similar results with a conventional approach would require a camera working at more than 1 Mfps for the single-pixel event detection, and 10 kfps for the whole multipixel event to be processed.

Cystic tumors of the pancreas. An update of the surgical experience in a single institution.

BACKGROUND: the aim of the present study was to analyze the clinicopathological features of patients undergoing pancreatic surgical resections due to cystic neoplasms of the pancreas. MATERIAL AND METHODS: demographic data, form of presentation, radiologic images and location of the tumors within the pancreas were analyzed. Data was also collected on the type of surgery (open/laparoscopic), postoperative complications and their severity and oncologic outcomes. RESULTS: eighty-two pancreatic resections were performed. The mean age of patients was 57 years and 49 (59%) were female. Forty-one tumors (50%) were incidental and the most frequent symptoms in the group of symptomatic patients were abdominal pain (63.4%) and weight loss (36.5%). Thirty-two tumors (39%) were located in the tail of the pancreas, 25 (30.5%) in the head and 20 (24.4%) in the body. Thirty-nine (47.5%) distal pancreatectomies, 16 central, ten duodenal pancreatectomies and one enucleation were performed; 40 (48.5%) were carried out laparoscopically. Mean hospital stay was ten days and eight patients (7%) experienced severe complications, one was a pancreatic fistula. Sixty-six tumors (80.5%) were recorded as non-invasive and 16 (19.5%) as invasive: seven intraductal mucinous papillary tumors, one cystic mucinous tumor, four solid pseudopapillary tumors and four cystic neuroendocrine tumors. There was a median follow-up of 64 months; disease-free survival at five and ten years was 97.4% in the patients with non-invasive tumors and 84.6% and 70.5% in the invasive tumors group (p < 0.01). CONCLUSIONS: fifty percent of cystic neoplasms of the pancreas are incidental. Two phenotypes exist, invasive and non-invasive.

Outcomes After Distal Pancreatectomy with Celiac Axis Resection for Pancreatic Cancer: A Pan-European Retrospective Cohort Study.

BACKGROUND: Western multicenter studies on distal pancreatectomy with celiac axis resection (DP-CAR), also known as the Appleby procedure, for locally advanced pancreatic cancer are lacking. We aimed to study overall survival, morbidity, mortality and the impact of preoperative hepatic artery embolization (PHAE). METHODS: Retrospective cohort study within the European-African Hepato-Pancreato-Biliary-Association, on DP-CAR between 1-1-2000 and 6-1-2016. Primary endpoint was overall survival. Secondary endpoints were radicality (R0-resection), 90-day mortality, major morbidity, and pancreatic fistulae (grade B/C). RESULTS: We included 68 patients from 20 hospitals in 12 countries. Postoperatively, 53% of patients had R0-resection, 25% major morbidity, 21% an ISGPS grade B/C pancreatic fistula, and 16% mortality. In total, 82% received (neo-)adjuvant chemotherapy and median overall survival in 62 patients with pancreatic ductal adenocarcinoma patients was 18 months (CI 10-37). We observed no impact of PHAE on ischemic complications. CONCLUSIONS: DP-CAR combined with chemotherapy for locally advanced pancreatic cancer is associated with acceptable overall survival. The 90-day mortality is too high and should be reduced. Future studies should investigate to what extent increasing surgical volume or better patient selection can improve outcomes.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas: clinicopathological features and long-term outcomes following a pancreatectomy.

OBJECTIVE: the objective of this study was to analyze the anatomical and clinical features and long-term oncologic outcomes of 25 patients that underwent surgery due to intraductal papillary mucinous neoplasm of the pancreas. MATERIAL AND METHODS: patients undergoing surgery for intraductal papillary mucinous neoplasm of the pancreas were identified from a prospective database of pancreatic resections. Demographic data, symptoms, type of surgery and type of lesion (branch type, main duct or mixed) were recorded. The lesions were classified into invasive (high grade dysplasia and carcinoma) and noninvasive (low- or intermediate-grade dysplasia). Postoperative complications were analyzed as well as the pattern of recurrence and disease-free survival at five and ten years. RESULTS: the most common symptoms in the 25 patients (14 males and eleven females) were abdominal pain and weight loss. Eight (32%) cases were diagnosed incidentally. Twelve (48%) of the lesions were of the branch type, three affected the main duct and ten (40%) were mixed. Twelve cephalic duodenopancreatectomies and seven total pancreatectomies were performed; three were central; two, distal; and one, enucleation. Seven cases (32%) had an invasive phenotype. Three patients had locoregional and distant recurrence at six, 16 and 46 months after surgery with a median follow-up of 7.7 years. Disease-free survival at five and ten years for the noninvasive type was 94% and 57% for invasive phenotypes (p < 0.05). CONCLUSIONS: intraductal papillary mucinous neoplasm is a heterogeneous entity with well differentiated phenotypes, which requires a tailored strategy and treatment, as established in the current consensus guidelines due to its malignant potential.

VI consensus document by the Spanish Liver Transplantation Society. / VI documento de consenso de la sociedad española de trasplante hepático (SETH).

The goal of the Spanish Liver Transplantation Society (La Sociedad Española de Trasplante Hepático) is to promote and create consensus documents about current topics in liver transplantation with a multidisciplinary approach. To this end, on October 20, 2016, the 6th Consensus Document Meeting was held, with the participation of experts from the 24 authorized Spanish liver transplantation programs. This Edition discusses the following subjects, whose summary is offered below: 1) limits of simultaneous liver-kidney transplantation; 2) limits of elective liver re-transplantation; and 3) liver transplantation after resection and hepatocellular carcinoma with factors for a poor prognosis. The consensus conclusions for each of these topics is provided below.

The Post-SIR-Spheres Surgery Study (P4S): Retrospective Analysis of Safety Following Hepatic Resection or Transplantation in Patients Previously Treated with Selective Internal Radiation Therapy with Yttrium-90 Resin Microspheres.

BACKGROUND: Reports show that selective internal radiation therapy (SIRT) may downsize inoperable liver tumors to resection or transplantation, or enable a bridge-to-transplant. A small-cohort study found that long-term survival in patients undergoing resection following SIRT appears possible but no robust studies on postsurgical safety outcomes exist. The Post-SIR-Spheres Surgery Study was an international, multicenter, retrospective study to assess safety outcomes of liver resection or transplantation following SIRT with yttrium-90 (Y-90) resin microspheres (SIR-Spheres®; Sirtex). METHODS: Data were captured retrospectively at participating SIRT centers, with Y-90 resin microspheres, surgery (resection or transplantation), and follow-up for all eligible patients. Primary endpoints were perioperative and 90-day postoperative morbidity and mortality. Standard statistical methods were used. RESULTS: The study included 100 patients [hepatocellular carcinoma: 49; metastatic colorectal cancer (mCRC): 30; cholangiocarcinoma, metastatic neuroendocrine tumor, other: 7 each]; 36% of patients had one or more lines of chemotherapy pre-SIRT. Sixty-three percent of patients had comorbidities, including hypertension (44%), diabetes (26%), and cardiopathy (16%). Post-SIRT, 71 patients were resected and 29 received a liver transplant. Grade 3+ peri/postoperative complications and any grade of liver failure were experienced by 24 and 7% of patients, respectively. Four patients died <90 days postsurgery; all were trisectionectomies (mCRC: 3; cholangiocarcinoma: 1) and typically had one or more previous chemotherapy lines and presurgical comorbidities. CONCLUSIONS: In 100 patients undergoing liver surgery after receiving SIRT, mortality and complication rates appeared acceptable given the risk profile of the recruited patients.

Short- and long-term outcomes of laparoscopic organ-sparing resection in pancreatic neuroendocrine tumors: a single-center experience.

BACKGROUND: Laparoscopic organ-sparing pancreatectomy (LOSP) is an ideal therapeutic option in selected cases of pancreatic neuroendocrine tumors (PNETs). Nevertheless, given the low frequency of PNETs, there is scarce evidence regarding short and particularly long-term outcomes of LOSP in this clinical setting. METHODS: All patients with PNETs who underwent surgery (under a LOSP policy) were retrospectively reviewed from a prospective database maintained at our center. Preoperative characteristics, operative data, pathological features and postoperative outcomes were analyzed. RESULTS: Between December 2003 and December 2015, 36 patients with PNETs underwent laparoscopic resections. Ten were functional tumors, 26 non-functional and 16 were "incidental" cases. The following procedures were performed: one enucleation, eight central pancreatectomies (LCP), one resection of the uncinate process and 26 distal pancreatectomies (DP) (15 of them laparoscopic vessels-preserving). There were no conversions to open surgery, and no drains were routinely left. Mean operative time was 288 min (SD 99). Hospital stay was 6 days. Eighteen patients (50%) experienced some complication of which most were mild (Clavien-Dindo I/II). Three postoperative bleedings occurred: two grade B/one grade C; two required laparoscopic reoperation. Thirteen (36.1%) patients developed peripancreatic fluid collections: two were symptomatic and were managed with transgastric drainage (one presented post-puncture abscesification requiring surgical drainage and splenectomy). Four patients (11%)-one DP and three LCP-developed new-onset pancreatogenic diabetes mellitus (NODM) in the long term. According to the European Neuroendocrine Tumor Society, 19 cases were stage I, seven IIA, two IIIA, one IIIB and seven stage IV. Over a mean follow-up of 51 months, two patients died, one due to recurrence of the tumor and another due to cirrhosis. CONCLUSIONS: The existing different surgical options must be individually considered according to the location and particular characteristics of every tumor. Results from this single-center study document the effectiveness of LOSP in selected cases of PNETs.

Liver mobilization and liver hanging for totally laparoscopic right hepatectomy: an easy way to do it.

PURPOSE: The purpose of this study is to describe a technical modification that facilitates right liver mobilization in laparoscopic right hepatectomy (LRH). METHODS: In the supine position, an inflatable device is placed under the patient's right chest. For right hemiliver mobilization, the table is placed in 30° anti-Trendelenburg and full-left tilt. Balloon inflation offers an additional 30° left inclination that places the patient in an almost left lateral position. Foot and lateral supports are placed to prevent patient slippage during changes in the patient positioning. RESULTS: From December 2013 to October 2015, this technique has been used in 10 consecutive LRH. The indications for these procedures were as follows: four donor hepatectomies for living donor liver transplant, three hepatocellular carcinomas and one peripheral cholangiocarcinoma in cirrhotic patients, one hepatocellular carcinoma in a non-cirrhotic patient, and one case of colorectal cancer metastases. In this period, it has also been used to facilitate mobilization and resection in the posterior segments of the liver in seven patients. In every case, right hemiliver mobilization was easily performed in a maximum time of 15 min and placement of a tape or plastic tube for liver hanging was prepared. We have not observed any complication directly attributable to the technique herein described (i.e. right brachialgia; arms, back or left flank pain) in the early or late postoperative follow-up. CONCLUSIONS: The additional left inclination obtained with the inflation of a balloon under the right chest facilitates right hemiliver mobilization. Its use may help in the performance and adoption of LRH.
