RESUMEN
INTRODUCTION: Although several studies report that the robotic approach is more costly than laparoscopy, the cost-effectiveness of robotic distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP) is still an issue. This study evaluates the cost-effectiveness of the RDP and LDP approaches across several Spanish centres. METHODS: This study is an observational, multicenter, national prospective study (ROBOCOSTES). For one year from 2022, all consecutive patients undergoing minimally invasive distal pancreatectomy were included, and clinical, QALY, and cost data were prospectively collected. The primary aim was to analyze the cost-effectiveness between RDP and LDP. RESULTS: During the study period, 80 procedures from 14 Spanish centres were analyzed. LDP had a shorter operative time than the RDP approach (192.2 min vs 241.3 min, p = 0.004). RDP showed a lower conversion rate (19.5% vs 2.5%, p = 0.006) and a lower splenectomy rate (60% vs 26.5%, p = 0.004). A statistically significant difference was reported for the Comprehensive Complication Index between the two study groups, favouring the robotic approach (12.7 vs 6.1, p = 0.022). RDP was associated with increased operative costs of 1600 euros (p < 0.031), while overall cost expenses resulted in being 1070.92 Euros higher than the LDP but without a statistically significant difference (p = 0.064). The mean QALYs at 90 days after surgery for RDP (0.9534) were higher than those of LDP (0.8882) (p = 0.030). At a willingness-to-pay threshold of 20,000 and 30,000 euros, there was a 62.64% and 71.30% probability that RDP was more cost-effective than LDP, respectively. CONCLUSIONS: The RDP procedure in the Spanish healthcare system appears more cost-effective than the LDP.
RESUMEN
BACKGROUND: The watch-and-wait (WW) strategy is a potential option for patients with rectal cancer who obtain a complete clinic response after neoadjuvant therapy. The aim of this study is to analyze the long-term oncological outcomes and perform a cost-effectiveness analysis in patients undergoing this strategy for rectal cancer. MATERIAL AND METHODS: The data of patients treated with the WW strategy were prospectively collected from January 2015 to January 2020. A control group was created, matched 1:1 from a pool of 480 patients undergoing total mesorectal excision. An independent company carried out the financial analysis. Clinical and oncological outcomes were analyzed in both groups. Outcome parameters included surgical and follow-up costs, quality-adjusted life years (QALYs), and the incremental cost per QALY gained or the incremental cost-effectiveness ratio (ICER). RESULTS: Forty patients were included in the WW group, with 40 patients in the surgical group. During a median follow-up period of 36 months, metastasis-free survival (MFS) and overall survival (OS) were similar in the two groups. In the WW group, nine (22%) local regrowths were detected in the first 2 years. The permanent stoma rate was slightly higher after salvage surgery in the WW group compared to the surgical group (48.5% vs 20%, p < 0.01). The cost-effectiveness analysis was slightly better for the WW group, especially for low rectal cancer compared to medium-high rectal cancer (ICER = - 108,642.1 vs ICER = - 42,423). CONCLUSIONS: The WW strategy in locally advanced rectal cancer offers similar oncological outcomes with respect to the surgical group and excellent results in quality of life and cost outcomes, especially for low rectal cancer. Nonetheless, the complex surgical field during salvage surgery can lead to a high permanent stoma rate; therefore, the careful selection of patients is mandatory.

BACKGROUND: Thanks to the introduction of radiomics, 3d reconstruction can be able to analyse tissues and recognise true hypertrophy from non-functioning tissue in patients treated with major hepatectomies with hepatic modulation.The aim of this study is to evaluate the performance of 3D Imaging Modelling in predict liver failure. METHODS: Patients submitted to major hepatectomies after hepatic modulation at Sanchinarro University Hospital from May 2015 to October 2019 were analysed. Three-dimensional reconstruction was realised before and after surgical treatment. The volumetry of Future Liver Remnant was calculated, distinguishing in Functional Future Liver Remnant (FRFx) i.e. true hypertrophy tissue and Anatomic Future Liver Remnant (FRL) i.e. hypertrophy plus no functional tissue (oedema/congestion) These volumes were analysed in patients with and without post hepatic liver failure. RESULTS: Twenty-four procedures were realised (11 ALPPS and 13 PVE followed by major hepatectomy). Post hepatic liver failure grade B and C occurred in 6 patients. The ROC curve showed a better AUC for FRFxV (74%) with respect to FRLV (54%) in prediction PHLF > B. The increase of anatomical FRL (iFRL) was superior in the ALPPS group (120%) with respect to the PVE group (73%) (p = 0,041), while the increase of functional FRFX (iFRFx) was 35% in the ALLPS group and 46% in the PVE group (p > 0,05), showing no difference in the two groups. CONCLUSION: The 3D reconstruction model can allow optimal surgical planning, and through the use of specific algorithms, can contribute to differential functioning liver parenchyma of the FLR.

Cancer is first a localized tissue disorder, whose soluble and exosomal molecules and invasive cells induce a host response providing the stromal components of the primary tumor microenvironment (TME). Once the TME is developed, cancer-derived molecules and cells can more efficiently spread out and a whole-body response takes place, whose pathophysiological changes may result in a paraneoplastic syndrome. Remote organ-specific prometastatic reactions may also occur at this time, facilitating metastatic activities of circulating tumor cells (CTCs) through premetastatic niche development at targeted organs. However, additional signaling factors from the inter-organ communication network involved in the pathophysiology and comorbidities of cancer patients may also regulate prometastatic reaction-stimulating effects of cancer and non-cancer tissue factors. This article provides a conceptual overview of our ongoing clinical research on the liver prometastatic reaction (LPR) of patients with colorectal cancer (CRC), their portal vein- and hepatic artery-driven LPR-Stimulating Factors (LPR-SF), and their resulting LPR-derived Metastasis-Stimulating Factors (LPR-MSF) acting on liver-invading CRC cells. In addition, we also provide new insights on the molecular subtyping of LPR-responsive cancer phenotypes in patients with CRC and melanoma; and on how to investigate and interpret the prometastatic infrastructure in the real pathophysiological context of patients with cancer undergoing surgical procedures and receiving pharmacological treatments with multiple side effects, including those affecting the LPR, its stimulating factors and responsive cancer phenotypes.

BACKGROUND: This meta-analysis aims to investigate the role of complete mesocolic excision (CME) in the treatment of right-side colon cancer when compared with standard right-side hemicolectomy, focusing on oncological outcomes, mortality and morbidity rates. MATERIALS AND METHODS: A systematic literature search was performed on MEDLINE and EMBASE archives, including studies on CME in right-side colon cancer. Primary outcomes were five-year disease-free survival and five-year overall survival. Secondary outcomes investigated were mortality and morbidity rates, intraoperative blood loss, anastomotic leakage, postoperative ileus, day of postoperative flatus, pulmonary infection, duration of hospital stay and number of lymph nodes harvested. RESULTS: Seventeen studies have been included in this meta-analysis for a total of 3918 patients. The five-year disease-free survival (DFS) and overall survival (OS) results improved in the CME group with respect to conventional right-side colectomy with an OR 1.88 (95% CI 1.02-3.45) and OR 2.77 (95% CI 1.33-5.74), respectively. The incidence of mortality and morbidity was comparable between the two groups. Moreover, conventional surgery time was faster than CME (MD 33.69 min, 95% CI 12.79-54.59), while no significant differences were reported in mean blood loss and hospital stay. Furthermore, the CME group showed a higher mean number of harvested lymph nodes (MD 7.08 lymph nodes 95% CI 4.90-9.27). CONCLUSION: Complete mesocolic excision of the right-side colectomy improves oncological outcomes without increasing mortality and morbidity rates compared to standard right-side hemicolectomy. CME should therefore be routinely performed in the treatment of right-side colon cancer.

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.

Among many factors leading to a worse functional prognosis in spinal meningioma (SM) surgery, in a previous study, we recognized anterior/anterolateral axial topography, sphincter involvement at first evaluation, surgery performed on a recurrence, and worse preoperative functional status. The purpose of this paper is to evaluate the cumulative weight of these factors on prognosis through a multinomial logistic regression model performed on an original evaluation scale designed by the authors on the ground of the experience of the neurosurgical departments of our University. The original SM database composed of 173 cases was classified in regard to sex, age, symptoms, axial and sagittal location, Simpson grade resection, and functional pre/postoperative status. Fine presurgical and follow-up reevaluations were available. The authors propose a scale (Spinal Meningiomas Prognostic Evaluation Score (SPES)) of preoperative evaluation to assess the surgery-related risk of neurological worsening experienced by the patients included in the present cohort. The authors describe a strong statistical association between the SPES and the follow-up Frankel and McCormick scores (r = - 460 and .441, p .001, both). Through a univariate ANOVA analysis, we disclosed that patients presenting scores 2 and 3 had a significantly higher association to lesser Frankel and McCormick postoperative scores, in respect to patients presenting SPES scores 0-1 (univariate ANOVA, p .008 and .011). Anterior or anterolateral axial location, operating on a recurrence of SM, sphincter involvement, and worse functional grade at onset present, along with the SPES scores are fairly predictive and reliable in respect to the long-term results of patients suffering from SM.

BACKGROUND: Pancreas divisum is a congenital embryological disease caused by a lack of fusion between the ventral and dorsal pancreatic ducts in the early stages of embryogenesis. Recurrent acute pancreatitis, chronic pancreatitis or chronic abdominal pain are the main clinical syndromes at presentation and occur in only 5% of the patients with pancreas divisum. This review aimed to discuss diagnosis and treatment strategies in patients with symptomatic pancreas divisum. DATA SOURCES: We report a literature review from 1990 up to January 2018 to explore the various diagnostic modalities and surgical techniques and results reported in the surgical treatment of pancreas divisum. RESULTS: There are limited reports available on this topic in the literature. We analyzed and described the main indications in the treatment of pancreas divisum, focusing on surgical treatment and a discussion of the different approaches. Furthermore, we report the results from our experience in two cases of pancreas divisum treated by pancreatic head resection with segmental duodenectomy (the Nakao procedure). CONCLUSIONS: Pancreas divisum is a common pancreatic malformation in which only a few patients develop a symptomatic disease. Surgical treatment is needed in case of endoscopic drainage failure and in cases complicated with chronic pancreatitis and local complications. Many techniques, of greater or lesser complexity, have been proposed.

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.

OBJECTIVE: The aim of this study is to compare the clinical and cost-effective outcomes of the open Lichtenstein repair (OL) and laparoscopic trans-abdominal preperitoneal (TAPP) repair for bilateral inguinal hernias. SUMMARY BACKGROUND DATA: A cost-effective analysis of laparoscopic versus open inguinal hernia repair is still not well addressed, especially regarding bilateral hernia. METHODS: This is a clinical and cost-effectiveness analysis within a randomized prospective study conducted at Sanchinarro University Hospital.Cases of primary, reducible bilateral inguinal hernia were included and randomized using a simple randomization program.The outcome parameters included surgical and postoperative costs, quality adjusted life years (QALY), and incremental cost per QALY gained or the incremental cost effectiveness ratio. RESULTS: Between March 2013 and January 2017, 165 patients were enrolled in this study (81 of them underwent TAPP and 84 OL).The TAPP procedure had less early postoperative pain (P = 0.037), a shorter length of stay (P = 0.001), and fewer postoperative complications (P = 0.002) when compared with the OL approach. The overall cost of TAPP procedure was higher compared with the OL cost (1,683.93&OV0556; vs 1192.83&OV0556;, P = 0.027). The mean QALYs at 1 year for TAPP (0.8094) was higher than that associated with OL (0.6765) (P = 0.018). At a willingness-to-pay threshold of 20,000 &OV0556; and 30,000 &OV0556;, there was a 95.38% and 97.96% probability that TAPP was more cost-effective relative to OL. CONCLUSIONS: The TAPP procedure for bilateral inguinal hernia appears to be more cost-effective compared with OL.

BACKGROUND: The degenerative lumbar spinal stenosis is one of the most commonly treated spinal disorders in older adults; despite its increasing frequency, it is not yet clear what the most effective therapy might be. The aim of this study is to investigate the very long term results of a homogenized cohort of patients suffering from lumbar spinal stenosis: the first subset of patients operated on with laminectomy and the second subset of patients was also advised to undergo laminectomy but never operated on. METHODS: Patients from both subgroups were advised to undergo surgery, according to the same criteria, in the period between 2000 and 2010 and were re-evaluated in the period between January and December 2016. RESULTS: Comparing the two subsets of patients, both suffering from clinically relevant LSS, the first subset returns a statistically significant clinical improvement at follow-up. The rate of excellent results decreases over years. Iatrogenic spinal instability incidence was found to be 3.8% in the present cohort. CONCLUSIONS: Although the improvement of the first postoperative years decreases over time and despite the lack of general consensus, the lack of established shared guidelines and the limitations of this research, the results support the utilisation of surgery for the management of this condition. LEVEL OF EVIDENCE: 3.

BACKGROUND: Hepatic resection of tumors invading the retrohepatic vena cava and hepatic veins are a challenge for surgeons, who consider them unresectable most of the time.1 , 2 Ex situ hepatectomy and liver autotransplantation has developed to improve resectability of these malignancies.3,4 METHODS: The patient was a 51-year-old man who had jaundice secondary to a intrahepatic cholangiocarcinoma 7 cm in diameter in the right lobe of the liver and the caudate lobe. A volumetric scan showed a future liver remnant (segments 2 and 3) not sufficient according to the body weight. The patient was considered to be unresectable by conventional resection due to the critical invasion to the retrohepatic vena cava together with the three hepatic veins. Therefore, an ex vivo extended right hepatectomy and autotransplantation were indicated. RESULTS: The patient underwent biliary decompression through a percutaneous transhepatic catheter and right portal vein embolization for left lobe hypertrophy. During the surgery, the liver was removed with the retrohepatic vena cava, which was replaced by a prosthetic graft without a veno-venous bypass. Ex vivo extended right hepatectomy was performed, and a prosthetic graft was used to replace the vena cava where the remaining left hepatic vein was anastomosed. The surgery duration was 9 h, and the anhepatic time was 4.5 h. The postoperative hospital stay was 19 days, and at this writing, 3 years later, the patient is disease-free. CONCLUSION: Ex vivo hepatectomy without veno-venous bypass should be considered a valid therapeutic option for selected patients with cholangiocarcinoma invading the retrohepatic vena cava.

The radio-guided occult lesion localization (ROLL) technique has been in use since the mid-1990s, mainly in breast surgery. Today, ROLL is used for numerous oncologic pathologies, including parathyroid lesions, melanomas, and colorectal tumors. We report a patient with an 11-mm left mesorectal solitary recurrence of a primary ovarian cancer in whom the ROLL technique was used to identify the implant. A radioisotope was introduced through a 22-gauge needle with endoscopic ultrasound technique using an linear echo endoscope. On the day of surgery, the patient's perianal region was scanned with a gamma probe to identify the area of maximal radioactivity, to determine the optimal placement of the incision over the lesion. After macroscopic excision of the lesion, radioactivity was measured in the lesion bed to ensure complete removal of affected tissues. In our case, the ROLL technique was performed safely for the detection and excision of a recurrent lesion of difficult identification. To our knowledge, this is the first reported case involving use of the ROLL technique to aid the excision of a mesorectal lesion.

BACKGROUND: Minimally invasive surgery has achieved worldwide acceptance in various fields, however, pancreatic surgery remains one of the most challenging abdominal procedures. In fact, the indication for robotic surgery in pancreatic disease has been controversial. The present study aimed to assess the safety and feasibility of robotic pancreatic resection. METHODS: We retrospectively reviewed our experience of robotic pancreatic resection done in Sanchinarro University Hospital. Clinicopathologic characteristics, and perioperative and postoperative outcomes were recorded and analyzed. RESULTS: From October 2010 to April 2016, 50 patients underwent robotic-assisted surgery for different pancreatic pathologies. All procedures were performed using the da Vinci robotic system. Of the 50 patients, 26 were male and 24 female. The average age of all patients was 62 years. Operative time was 370 minutes. Among the procedures performed were 16 pancreaticoduodenectomies (PD), 23 distal pan-createctomies (DP), 11 tumor enucleations (TE). The mean hospital stay was 17.6 days in PD group, 9.0 days in DP group and 8.4 days in TE group. Pancreatic fistula occurred in 10 cases (20%), 2 after PD, 3 after DP, and 5 after TE. Four patients had postoperative transfusion in PD group and one in DP group. Conversion to open laparotomy occurred in four patients (8%). No serious intraoperative complications were observed. CONCLUSIONS: From our early experience, robotic pancreatic surgery is a safe and feasible procedure. Further experience and follow-up are required to confirm the role of robotic approach in pancreatic surgery.

PURPOSE: Aim of this study is to compare late degenerative MRI changes in a subset of patients operated on with ACDF to a second subset of patients presenting indication to ACDF but never operated on. METHODS: Patients from both subgroups received surgical indication according to the same criteria. Both subgroups underwent a cervical spine MRI in 2004-2005 and 10 years later in 2015. These MRI scans were retrospectively evaluated with a cervical spine ageing scale. RESULTS: Comparing the two subset of patients both suffering from clinically relevant single-level disease returns no statistically significant difference in the degenerative condition of posterior ligaments, presence of degenerative spondylolisthesis, foraminal stenosis, diameter of the spinal canal, Modic alteration, and intervertebral discs degeneration at 10-year follow-up. CONCLUSIONS: The adjacent segment degeneration represents, in the present cohort, a result of the natural history of cervical spondylosis rather than a consequence of fusion.

BACKGROUND: Surgical resection of a tumor with thrombus formation extending from the inferior vena cava (IVC) to the right atrium can be performed without the use of a cardiopulmonary bypass. However, this technique is not widely known or used by general surgeons. Our aim was to present our experience in a general surgical unit setting and to present a literature review. METHODS: Retrospective analysis of 3 cases with successful cavoatrial thrombectomy without the use of cardiopulmonary bypass by a transabdominal, transdiaphragmatic, and transpericardic approach. We also performed a review of the English literature of this procedure. RESULTS: Three cases are presented: right-sided hepatocellular carcinoma, a right renal carcinoma, and a recurrent hepatic hydatid cyst all which required surgery. An approach from the right atrium to the IVC was used, and then, after cavoatrial occlusion, a cavotomy was performed to carry out the thrombectomy. In all cases, a transesophageal echocardiography was performed during surgery. We only found 6 other similar cases that were performed successfully in current medical literature. CONCLUSIONS: Our own experiences and cases identified through a literature review demonstrate that a thrombectomy for IVC thrombus in the setting of abdominal pathology can be performed successfully in selected cases without the support of cardiopulmonary bypass.

CONTEXT: Arterial pseudoaneurysm is an uncommon lethal complication following hepato-pancreato-biliary surgery. OBJECTIVE: Aim of this study is to present and discuss the experience of a high volume oncological center. METHODS: Since 2007 all major surgeries performed at Sanchinarro Oncological Center have been included in a prospective database looking for postoperative arterial pseudonaurysm. RESULTS: Until June 2014, among 559 hepato-pancreato-biliary procedures, a total of 14 arterial pseudoaneurysms have been identified (2.5%). Sentinel bleeding was in 57% of cases. Failed arterial embolization occurred in 2 cases. Overall mortality rate was 28.5%. We also identified 3 asymptomatic pseudoaneurysms, one of them managed without embolization, developing a sudden bleeding and died after surgery. CONCLUSIONS: According to our experience, pseudoaneurysm incidence is higher than reported in current literature and it can be successfully managed through arterial embolization. Furthermore, we found 3 asymptomatic pseudoaneurysms, whose management is still controversial.
RESUMEN
PURPOSE: This article aims at presenting a scale that, through the analysis of MRI images, clearly charts the various degenerative stages of the cervical spine and establishes its biological age. We have created this scale by summing together various scores linked to a selection of parameters according to which MRI images are analyzed. METHOD: We examined 423 cervical spine MRI scans, belonging to patients who had been admitted to the Medical Imaging Service of the Military Hospital of Rome between January 2010 and July 2011. We selected 6 parameters for the analysis of the MRI scans of the cervical spine: (1) the degeneration of the intervertebral discs, (2) the degeneration of the yellow ligaments, (3) the degeneration of the vertebral bodies, (4) the possible presence of spondylolistheses, (5) the presence or absence of foraminal stenosis, and (6) the diameter of the spinal canal. We assigned to each parameter a score system based on a graduated scale. The cervical spine physiological age can be determined by summing up the scores obtained for each parameter. RESULTS: We submitted the data obtained from the study to a statistical enquiry. The results of the enquiry confirmed the suitability of the parameters selected for the evaluation of the aging process of the cervical spine. CONCLUSIONS: The effectiveness of the various treatments for cervical spine degenerative disorders is influenced by the overall anatomical conditions of the cervical spine. Up until now there has been no objective criterion for the evaluation of these anatomical conditions. We believe that this scale will be a useful tool to homogenize retrospective studies and to correctly set up prospective studies on the degenerative conditions of the cervical spine and relative treatments.

As surgical resection remains the only hope for cure in pancreatic cancer (PC), more aggressive surgical approaches have been advocated to increase resection rates. Venous resection demonstrated to be a feasible technique in experienced centers, increasing survival. In contrast, arterial resection is still an issue of debate, continuing to be considered a general contraindication to resection. In the last years there have been significant advances in surgical techniques and postoperative management which have dramatically reduced mortality and morbidity of major pancreatic resections. Furthermore, advances in multimodal neo-adjuvant and adjuvant treatments, as well as the better understanding of tumor biology and new diagnostic options have increased overall survival. In this article we highlight some of the important points that a modern pancreatic surgeon should take into account in the management of PC with arterial involvement in light of the recent advances.
