RESUMEN
BACKGROUND: The prognostic factors for long-term survival after curative resection of pancreatic adenocarcinoma are still poorly understood. The purpose of this study was to identify the prognostic factors of long-term survival after resection of pancreatic adenocarcinoma based on actual 5-year survival including different lymph node status classifications. METHOD: A total of 106 patients who underwent pancreatectomy were enrolled at our institution and retrospectively analyzed according to actual survival (> vs < 5 years), as well as several currently available node classifications: N0/N1, N0/N1/N2, and lymph-node ratio (LNR) including multivariate logistic regression. RESULTS: The actual 5-year overall survival rate of the series was 12.26%. In a univariate analysis, operative blood loss and blood transfusion, completion of adjuvant treatment, histological differentiation, perineural invasion, N0/N1, N0/N1/N2 and LNR were significant predictive factors for actual long-term survival. A multivariate analysis showed that only N0/N1 was an independent predictive factor for actual 5-year survival (OR: 1.593; 0.730-1.325; p= 0.264). CONCLUSION: The nodal involved status is the strongest independent unfavorable factor for actual long-term survival after pancreatic resection for adenocarcinoma.

INTRODUCTION: Locally advanced pancreatic cancer (LAPC) is a highly malignant carcinoma with an extremely poor prognosis. Vascular venous invasion is a frequent finding in patients with pancreatic cancer. The aim of this study was to investigate the morbidity, mortality, and survival of patients with advanced pancreatic cancer. METHODS: We retrospectively reviewed our experience of 65 consecutive pancreatic surgeries with venous resection for pancreatic cancer in three hospitals: Ramon y Cajal (Madrid, Spain) from 2002 to 2004, Monteprincipe University Hospital (Madrid, Spain) from 2005 to 2006 and Sanchinarro University Hospital (Madrid, Spain) from 2007 to December 2017. Prognostic factors were analyzed by the log-rank test and a multivariate proportional hazard regression analysis. RESULTS: Major venous reconstruction was performed by primary lateral venorrhaphy in 11 patients (17%), primary end-to-end anastomosis in 46 (70.7%) and reconstruction with a Gore-Tex® patch (W.L. Gore & Associates, Inc., Flagstaff, AZ) in 8 (12.3%). In 58% of the patients, the pathological examination showed infiltration of the vascular specimen. About 85% of the procedures performed were R0. The perioperative morbidity rate with Dindo-Clavien classification = III was 21.5%. Tumor size and nodal status were the only prognostic variables, which significantly decreased survival by a multivariate analysis. CONCLUSIONS: Major vascular resection to achieve macroscopic tumor clearance can be performed safely with acceptable operative morbidity and mortality. Nevertheless, it is justified only in carefully selected cases.

AIM: The aim of this meta-analysis is to compare perioperative outcomes and costs of robotic and laparoscopic distal pancreatectomy (RDP and LDP). MATERIAL AND METHODS: In accordance with the PRISMA guidelines, we searched Medline, EMBASE, Cochrane and Web of Science for reports published before December 2020. RESULTS: The literature search identified 11 papers (1 187 patients). RDP showed a lower conversion rate (odds ratio: 2.56, 95% confidence intervals [CI]: 1.31 to 5.00) with no significant differences in bleeding and operative time, complications ≥ Clavien-Dindo grade III, pancreatic fistulas and length of stay. Despite RDP presenting higher costs in all included studies, none of these differences were significant. However, RDP showed higher total costs than LDP (standardized mean differences [SMD]: -1.18, 95% CI: -1.97 to -0.39). A subgroup analysis according to the continent of origin showed that studies coming from Asian research groups kept showing significant differences (SMD: -2.62, 95% CI: -3.38 to -1.85), while Western groups did not confirm these findings. CONCLUSION: Based on low-quality evidence, despite some potential technical advantages, RDP still seems to be costlier than LDP.

AIM: The aim of this study is to compare clinical and oncological outcomes of robot-assisted right colectomy with those of conventional laparoscopy-assisted right colectomy, reporting for the first time in literature, a cost-effectiveness analysis. METHODS: This is a case-matched prospective non-randomized study conducted from October 2013 to October 2017 at Sanchinarro University Hospital, Madrid. Patients with right-sided colonic adenocarcinoma or adenoma, not suitable endoscopic resection were treated with robot-assisted right colectomy and a propensity score-matched (1:1) was used to balance preoperative characteristics of a laparoscopic control group. Perioperative, postoperative, long-term oncological results and costs were analysed, and quality-adjusted life years (QALY), and the cost-effectiveness ratio (ICER) were calculated. The primary end point was to compare the cost-effectiveness differences between both groups. A willingness-to-pay of 20,000 and 30,000 per QALY was used as a threshold to recognize which treatment was most cost effective. RESULTS: Thirty-five robot-assisted right colectomies were included and a group of 35 laparoscopy-assisted right colectomy was selected. Compared with the laparoscopic group, the robotic group was associated with longer operation times (243 min vs. 179 min, p < 0.001). No significant difference was observed in terms of total costs between the robotic and laparoscopic groups (9455.14 vs 8227.50 respectively, p = 0.21). At a willingness-to-pay threshold of 20,000 and 30,000, there was a 78.78-95.04% probability that the robotic group was cost effective relative to laparoscopic group. CONCLUSION: Robot-assisted right colectomy is a safe and feasible technique and is a cost-effective procedure.

BACKGROUND: Giant inguinoscrotal (GIS) hernias are rarely encountered in clinical settings and are often associated with mental neglect for many years. This type of hernia is defined as "giant" if it descends below the mid-point of the inner thigh of a patient in an upright position. The laparoscopic repair approach of a GIS hernia is technically challenging. It has been claimed that laparoscopic surgery has several advantages over the open surgical approach, with less pain and an earlier recovery. The aim of this video is to evaluate the efficacy of TAPP (laparoscopic transabdominal preperitoneal) in order to treat a GIS hernia. CASE PRESENTATION: A 65-year-old male without a relevant past medical history was admitted to the emergency service with abdominal pain, belching and nausea. He denied any other symptoms, and no previous surgical operations were recorded. Physical examination showed a large mass in the left scrotum below the mid-point of the inner thigh of the patient in an upright position. A CT scan confirmed the diagnosis of a GIS. A laparoscopic TAPP procedure was decided upon as the best course of treatment. RESULTS: The patient underwent a successful repair procedure. The operation time was 150â¯min. No intraoperative blood transfusion was necessary. The patient's diet was resumed on the first day post surgery, and the postoperative hospital stay was three days. CONCLUSIONS: Laparoscopic TAPP repair is a safe and feasible method for surgically managing GIS hernias.
