RESUMO
BACKGROUND: Three-dimensional reconstruction of the liver offers several advantages to the surgeon before and during liver resection. This review discusses the factors behind the use of liver 3-D reconstruction. METHODS: Systematic electronic search, according to PRISMA criteria, was performed. A literature search of scientific papers was performed until October 2023. Articles were chosen based on reference to 3-D liver reconstruction and their use in liver surgery. GRADE methodology and the modified Newcastle-Ottawa scale were used to assess the quality of the studies. RESULTS: The research included 47 articles and 7724 patients were analyzed. Preoperative planning was performed with 3-D liver reconstruction in the 87.2% of the studies. Most of preoperative 3-D liver reconstructions were performed in the planning of complex or major hepatectomies. Complex hepatectomies were performed in 64.3% patients. The 55.3% of the studies reported an improved navigation and accuracy during liver resection. Four studies (8.6%) on living donor liver transplant (LDLT) concluded that 3-D liver reconstruction is useful for graft selection and vascular preservation. Nine papers (19.1%) reported an accurate measurement of future liver remnant. CONCLUSION: Liver 3-D reconstruction helps surgeons in the planning of liver surgery, especially in liver graft and complex liver resections, increasing the accuracy of the surgical resection.
RESUMO
Microsatellite Instability (MSI-H) occurs in approximately 15% of non-metastatic colon cancers, influencing patient outcomes positively compared to microsatellite stable (MSS) cancers. This systematic review focuses on the prognostic significance of KRAS, NRAS, and BRAF mutations within MSI-H colon cancer. Through comprehensive searches in databases like MEDLINE, EMBASE, and others until 1 January 2024, we selected 8 pertinent studies from an initial pool of 1918. These studies, encompassing nine trials and five observational studies involving 13,273 patients, provided insights into disease-free survival (DFS), survival after recurrence, and overall survival. The pooled data suggest that while KRAS and BRAF mutations typically predict poorer outcomes in MSS colorectal cancer, their impact is less pronounced in MSI contexts, with implications varying across different stages of cancer and treatment responses. In particular, adverse effects of these mutations manifest significantly upon recurrence rather than affecting immediate DFS. Our findings confirm the complex interplay between genetic mutations and MSI status, emphasizing the nuanced role of MSI in modifying the prognostic implications of KRAS, NRAS, and BRAF mutations in colon cancer. This review underscores the importance of considering MSI alongside mutational status in the clinical decision-making process, aiming to tailor therapeutic strategies more effectively for colon cancer patients.
RESUMO
Introduction: Preoperative progressive pneumoperitoneum (PPP) and botulinum toxin A (BTX) have been used together in the preoperative preparation of patients with loss of domain hernias. This study aims to evaluate the efficacy and safety of the combined use of PPP and BTX. Methods: A systematic electronic search was performed according to the PRISMA criteria. A literature search of scientific articles was conducted up to December 2023. Articles were chosen based on the reference to BTX and PPP in loss of domain ventral hernias with a defect width greater than 10 cm before surgery. The GRADE methodology and the modified Newcastle-Ottawa scale were used to assess the quality of the studies. Results: The research yielded seven articles, with 217 patients analysed in total. BTX was performed 29.5 ± 1.7 days before surgery and PPP was inflated 14.8 ± 5.8 days before surgery. PPP complications were reported in 25.6% of patients, The average reduction of the volume of hernia (VH)/volume of the abdominal cavity (VAC) ratio was 7.6% (range 0.9%-15%). Only 40 patients (18.4%) required a PCS or TAR to repair the loss of domain hernias. The SSI and SSO rates were 17.5% and 26.2%, respectively. No differences in SSI and SSO rates were found between the different repair techniques. The recurrence rate was 5.9% (13/217). Recurrence was significantly higher in patients who underwent IPOM repair than other techniques (p < 0.001). Conclusion: BTX and PPP may be useful tools for the management of loss of domain hernias presenting lower SSI and SSO. The combination of BTX and PPP reduces the use of more invasive repair techniques.
RESUMO
Introduction: The minimally invasive approach of endoscopic ultrasound (EUS)-guided procedures for cholecystocholedocholithiasis, such as EUS-guided gallbladder drainage (EUS-GBD), EUS-guided rendezvous (EUS-RV), and EUS-guided biliary drainage (EUS-BD), is affirmed as an effective treatment for patients with acute cholecystitis (AC) who are unfit for surgery and for patients with common bile duct stones (CBDSs) who have experienced a previous ERCP failure. Furthermore, in cases of difficult CBDS extraction during endoscopic retrograde cholangiopancreatography (ERCP), cholangioscopy-guided electrohydraulic lithotripsy (CS-EHL) has showed optimal results. The main objective of our study was to evaluate the effectiveness of EUS-GBD and percutaneous gallbladder drainage (PT-GBD) in patients with AC who are unfit for surgery. We also aimed to evaluate the efficacy of EUS-GBD, EUS-BD, and EUS-RV following ERCP failure and the effectiveness of CS-EHL for difficult CBDS extraction in our hospital. The secondary aim was to examine the safety of these procedures. Materials and methods: We conducted a retrospective evaluation of all the EUS-GBD, PT-GBD, EUS-BD, EUS-RV, and CS-EHL procedures, which were prospectively collected in the gastroenterology and digestive endoscopy unit and the general surgery unit from January 2020 to June 2023. The efficacy was expressed in terms of technical and clinical success rates, while safety was assessed based on the rate of adverse events (AEs). Results: We enrolled 83 patients with AC and high surgical risk. Among them, 57 patients (68.7%, 24/57 male, median age 85 ± 11 years) underwent EUS-GBD, and 26 (31.3%, 19/26 male, median age 83 ± 7 years) underwent PT-GBD. The technical and clinical success rates were 96.5 and 100% for EUS-GBD, and 96.1 and 92% for PT-GBD. The AEs for EUS-GBD were 1.7%, and for PT-GBD, it was 12%. ERCP for CBDS extraction failed in 77 patients. Among them, 73 patients (94.8%) underwent EUS-RV with technical and clinical success rates of 72.6% (53/73) and 100%, respectively. No AEs were reported. Four out of 77 patients were directly treated with EUS-BD for pyloric inflammatory stenosis. In 12 patients (16.4%), following unsuccessful EUS-RV with a CBD diameter ≥ 12 mm, an EUS-BD was performed. Both technical and clinical success rates for EUS-BD were 100%, and no AEs were reported. EUS-GBD was the treatment of choice for the remaining 8 (10.9%) patients after failure of both ERCP and EUS-RV. The procedure had high technical and clinical success rates (both at 100%), and no AEs were reported. The 12 difficult CBDS extraction treated with CS-EHL also showed high technical and clinical success rates (both at 100%), with no reported AEs. Conclusion: The minimally invasive approach for cholecystocholedocholithiasis, especially EUS-guided procedures, had high efficacy and safety in treating AC in high-risk surgical patients and CBDS extraction after a previously unsuccessful ERCP.
RESUMO
BACKGROUND: to test the association with overall survival (OS) of low attenuation areas (LAAs) quantified by staging computed tomography (CT) of patients who underwent radical surgery for nonsmall-cell lung cancer (NSCLC). METHODS: patients who underwent radical surgery for NSCLC at our institution between 1 January 2017 and 30 November 2021 were retrospectively evaluated. Patients who performed staging or follow-up CTs in other institutions, who received lung radiotherapy or chemotherapy, and who underwent previous lung surgery were excluded. At staging and 12-months follow-up CT, LAAs defined as voxels <-950 Hounsfield units, were extracted by software. The percent of LAAs relative to whole-lung volume (%LAAs) and the ratio between LAAs in the lobe to resect and whole-lung LAAs (%LAAs lobe ratio) were calculated. Cox proportional hazards regression analysis was used to test the association between OS and LAAs. RESULTS: the final sample included 75 patients (median age 70 years, IQR 63-75 years; females 29/75, 39%). It identified a significant association with OS for pathological stage III (HR, 6.50; 95%CI, 1.11-37.92; p = 0.038), staging CT %LAAs ≥ 5% (HR, 7.27; 95%CI, 1.60-32.96; p = 0.010), and staging CT %LAA lobe ratio > 10% (HR, 0.24; 95%CI 0.05-0.94; p = 0.046). CONCLUSIONS: in patients with NSCLC who underwent radical surgery, a %LAAs ≥ 5% and a %LAA lobe ratio > 10% at staging CT are predictors, respectively, of shorter and longer OS. The LAA ratio to the whole lung at staging CT could be a critical factor to predict the overall survival of the NSCLC patients treated by surgery.
RESUMO
BACKGROUND/AIM: Complete clinical response in rectal cancer after neoadjuvant chemo-radiotherapy is challenging. Indeed, indication to surgery vs. "watch and wait" is a debate due the poor predictive value of restaging exams in order to identify a pathological complete response (pCR). Improving the knowledge on mutational pathways such as MAPK/ERK could be helpful in assessing the real impact of disease on prognosis and in choosing the best therapeutic target. This study aimed to evaluate the significance of biomolecular parameters as prognostic factors in patients undergoing radical surgery after chemo-radiotherapy. PATIENTS AND METHODS: A retrospective analysis was performed including 39 patients who had undergone radical surgery after neoadjuvant chemo-radiotherapy for rectal adenocarcinoma stage II-III through additional evaluation of the following biomolecular markers on surgical specimens: exons 2, 3 and 4 of the KRAS and NRAS genes and exon 15 of BRAF by pyrosequencing. Kaplan-Meier survival curves were plotted to evaluate the association of pathologic response and RAS status with progression-free survival (PFS) and overall survival (OS). The log-rank test was used to assess statistical differences among the survival curves. RESULTS: Data analysis showed RAS mutation in 15 patients (38.46%). pCR was achieved in seven patients (18%), including only two RAS mutation cases. The distribution of evaluated variables was homogeneous in the two groups based on pathological response. The Kaplan-Meier curve showed poor outcomes in OS and PFS in patients with RAS mutation (p=0.0022 and p=0.000392, respectively), but no significant differences based on pathological response for both OS and PFS. CONCLUSION: RAS mutation seems to be related to poor prognosis and increased risk of recurrence in rectal cancer patients undergoing radical surgery after chemo-radiotherapy.

Background: To test the agreement between postoperative pulmonary function tests 12 months after surgery (mpo-PFTs) for non-small cell lung cancer (NSCLC) and predicted lung function based on the quantification of well-aerated lung (WAL) at staging CT (sCT). Methods: We included patients with NSCLC who underwent lobectomy or segmentectomy without a history of thoracic radiotherapy or chemotherapy treatment with the availability of PFTs at 12 months follow-up. Postoperative predictive (ppo) lung function was calculated using the resected lobe WAL (the lung volume between −950 and −750 HU) at sCT. The Spearman correlation coefficient (rho) and intraclass correlation coefficient (ICC) were used to the test the agreement between WAL ppo-PFTs and mpo-PFTs. Results: the study included 40 patients (68 years-old, IQR 62−74 years-old; 26/40, 65% males). The WAL ppo-forced expiratory volume in 1 s (FEV1) and the ppo-diffusing capacity of the lung for carbon monoxide (%DLCO) were significantly correlated with corresponding mpo-PFTs (rho = 0.842 and 0.717 respectively; p < 0.001). The agreement with the corresponding mpo-PFTs of WAL ppo-FEV1 was excellent (ICC 0.904), while it was good (ICC 0.770) for WAL ppo-%DLCO. Conclusions: WAL ppo-FEV1 and WAL ppo-%DLCO at sCT showed, respectively, excellent and good agreement with corresponding mpo-PFTs measured 12 months after surgery for NSCLC. WAL is an easy parameter obtained by staging CT that can be used to estimate post-resection lung function for patients with borderline pulmonary function undergoing lung surgery.
RESUMO
PURPOSE: Surgery is the main treatment for non-metastatic colorectal cancer. Despite huge improvements in perioperative care, colorectal surgery is still associated with a significant burden of postoperative complications and ultimately costs for healthcare organizations. Systematic clinical auditing activity has already proven to be effective in measuring and improving clinical outcomes, and for this reason, we decided to evaluate its impact in a large area of northern Italy. METHODS: The Emilia-Romagna Surgical Colorectal Audit (ESCA) is an observational, multicentric, retro-prospective study, carried out by 7 hospitals located in the Emilia-Romagna region. All consecutive patients undergoing surgery for colorectal cancer during a 54-month study period will be enrolled. Data regarding baseline conditions, preoperative diagnostic work-up, surgery and postoperative course will be collected in a dedicated case report form. Primary outcomes regard postoperative complications and mortality. Secondary outcomes include each center's adherence to the auditing (enrolment rate) and evaluation of the systematic feedback activity on key performance indicators for the entire perioperative process. CONCLUSION: This protocol describes the methodology of the Emilia-Romagna Surgical Colorectal Audit. The study will provide real-world clinical data essential for benchmarking and feedback activity, to positively impact outcomes and ultimately to improve the entire healthcare process of patients undergoing colorectal cancer surgery. CLINICAL TRIAL REGISTRATION: The study ESCA is registered on the clinicaltrials.gov platform (Identifier: NCT03982641).

BACKGROUND AND AIM: Dysregulation of iron metabolism and hyper-inflammation are two key points in the pathogenesis of coronavirus disease 2019 (COVID-19). Since high hepcidin levels and low serum iron can predict COVID-19 severity and mortality, we decided to investigate iron metabolism and inflammatory response in 32 COVID-19 adult patients with a diagnosis of COVID-19 defined by a positive result of RT-PCR nasopharyngeal swab, and admitted to an Italian emergency department for acute respiratory failure at different degree. METHODS: Patients were stratified in 3 groups based on PaO2/FiO2 ratio at admission: 13 (41%) were normoxemic at rest and suffered from exertional dyspnea (group 1); 14 (44%) had a mild respiratory failure (group 2), and 5 (15%) a severe hypoxiemia (group 3). RESULTS: White blood cells were significantly higher in group 3, while lymphocytes and hemoglobin were significantly reduced. Serum iron, transferrin saturation, non-transferrin-bound iron (NTBI) and ferritin were significantly increased in group 2. All the groups showed high hepcidin levels, but in group 3 this parameter was significantly altered. It is noteworthy that in group 1 inflammatory and oxidative indices were both within the normal range. CONCLUSIONS: We are aware that our study has some limitations, the small number of enrolled patients and the short period of data collection, but few works have been performed in the Emergency Room. However, we strongly believe that our results confirm the pivotal role of both iron metabolism dysregulation and hyper-inflammatory response in the pathogenesis of tissue and organ damage in COVID-19 patients.

INTRODUCTION: A considerable step forward in low rectal cancer resection has been done in the last decades. Maintaining total mesorectal excision as the gold standard treatment, new techniques such as Trans-Anal Mini-Invasive Surgery (TAMIS) and Trans-Anal Total Mesorectal Excision (TATME), which have been added to improve skills in laparoscopic and robotic surgery, currently represent the advancement of this procedure. Despite improvements in surgical techniques, complications after low anterior resection for rectal cancer still remain a challenge. Drainage and colostomy are the main treatments used to overcome the problem caused by anastomosis failure, and most patients will never been restored. Different techniques of redo surgery could be proposed to deal complex cases, although remaining high risk procedures. CASE PRESENTATION: We present two clinical cases with a late complication of the colorectal anastomosis: one with a late leakage of low colorectal anastomoses, treated with Hartman procedure, that developed a pelvic chronic sinus; the another one with complete anastomotic disruption after massive suture bleeding; both treated with delayed pull-through anastomosis, according to Turnbull-Cutait technique. We also made a review of relative literature, in order to back our therapeutic iters. DISCUSSION: Both the procedures were carried out satisfactorily, with restoration of intestinal continuity and good anastomotic result. It allows the resolutions of the chronic sepsis caused by the pelvic sinus and maintenance of intestinal continuity with a good Wexner incontinence score. Literary review demonstrated that this procedure still remains undervalued and not widely exploited. CONCLUSION: Delayed pull-through coloanal anastomosis could be considered as a valid option, in order to preserve intestinal continuity in septic or complicated low colorectal anastomosis.
RESUMO
When colorectal cancer presents with liver metastasis, hepatic resection remains the most important factor in prolonging survival, and new paradigms have been proposed to augment resectability. An adequate liver remnant and vascularisation are the only limits in complex liver resection, and parenchyma-sparing surgery is a strategy for minimising the complications, preserving liver function, and allowing patients to undergo further liver resection. The laparoscopic approach represents a new challenge, especially when lesions are located in the superior or posterior part of the liver. We discuss the case of an 81-year-old patient with a single synchronous liver metastasis involving the left hepatic vein and leaning into the middle hepatic vein at the common trunk, where we performed a simultaneous laparoscopic colonic resection with a left sectionectomy extended to segment 4a. The strategic approach to the Arantius ligament by joining the left and middle hepatic vein allowed us to avoid a major liver hepatectomy, preserve the liver parenchyma, reduce complications, enhance patient recovery, and perform the entire procedure by laparoscopy. Our example suggests that the Arantius approach to the left hepatic vein and the common trunk could be a feasible approach to consider in laparoscopic surgery for lesions located in their proximity.
RESUMO
The cause of pleural empyema is bacterial pneumonia and three stages has been described in the evolution of this disease: exudative, fibrino-purulent and organizational phases. The first therapeutic intervention is the antibiotic therapy; where pharmacological therapy alone is not sufficient to eradicate the infection, it is also necessary a surgical treatment. Since the province of Piacenza having been in the epicenter area during the first Sars-Cov 2 pandemic wave in March 2020 and the number of patients with Covid-related pneumonia required invasive and non-invasive respiratory support, had a considerable organizational impact on pulmonology and respiratory unit, hindering an optimal treatment of the bacterial pneumonia both in community as well as in the hospital. Among the many "collateral" damages of the epidemiological wave of the infection with Sars Cov-2, we have been able to observe in our Hospital, also an increase of pulmonary empyemas diagnosed at an advanced stage for what we believe to be organizational and social causes directly related to the pandemic: in order to cope with the emergency the Unit of Pneumology has been since March nearly uninterruptedly dedicated to the exclusive treatment of covid patients so the pneumologist has been removed due to the need from outpatient and residential management of general pneumology.

OBJECTIVE: The aim of this study is to compare early and follow-up outcomes of late open conversions (LOC, with complete or partial endograft explantation) and semi-conversions (SC, with endograft preservation) after endovascular aneurysm repair in a multicenter experience. METHODS: All LOC and SC performed from 1997 to 2020 in 11 vascular centers were compared. Endograft infections or thrombosis were excluded. Primary endpoints were early mortality and long-term survival estimates. Secondary endpoints were differences in postoperative complication rates and conversion-related complications during follow-up. RESULTS: In the considered period, 347 patients underwent surgery for endovascular aneurysm repair complications. Among these, 270 were operated on for endoleaks (222 LOC, 48 SC). The two groups were homogeneous in terms of American Society of Anesthesiologists score (LOC, 3.2 ± 0.7; SC, 3 ± 0.5; P = .128) and main endograft characteristics (suprarenal fixation, bifurcated/aorto-uni-iliac configuration). The mean age was 75 ± 8 years for LOC and 79 ± 7 years for SC (P = .009). Reasons for LOC were: 62.2% (138/222) type I endoleak, 21.6% (48/222) type II endoleak, 7.7% (17/222) type III endoleak, and 8.5% (19/222) endotension. Indications for SC were: 64.6% (31/48) type II endoleak, 33.3% (16/48) type I endoleak, and 2.1% (1/48) type III endoleak. Thirty-day mortality was 12.2% (27/222) in the LOC group, and 10.4% (5/48) in the SC group (P = .73). Postoperative complication rate was higher in the LOC group (45.5% vs 29.2%; P = .04). The estimated survival rate after LOC was 80% at 1 year and 64% at 5 years; after SC, it was 72% at 1 year and 37% at 5 years (log-rank P = .01). During the median follow-up of 21.5 months (interquartile range, 2.4-61 months), an endoleak after SC was found in the 38.3% of the cases; sac growth was recorded in the 27.7% of SC patients. CONCLUSIONS: SC has an early benefit over LOC in terms of reduced postoperative complications but has a significantly inferior mid-term survival. The high rates of persistent and/or recurrent endoleaks reduce SC durability.

OBJECTIVE: The Communication Assessment Tool (CAT) has previously been translated and adapted to the Italian context. This national study aimed to validate the CAT and evaluate communication skills of practicing surgeons from the patient perspective. METHODS: CAT consists of 14 items associated with a 5-point scale (5 = excellent); results are reported as the percent of ''excellent'' scores. It was administered to 920 consenting outpatients aged 18-84 in 26 Italian surgical departments. RESULTS: The largest age group was 45-64 (43.8%); 52.2% of the sample was male. Scores ranged from 44.6% to 66.6% excellent. The highest-scoring items were "Treated me with respect" (66.6%), "Gave me as much information as I wanted" (66.3%) and "Talked in terms I could understand" (66.0%); the lowest was "Encouraged me to ask questions" (44.6%). Significant differences were associated with age (18-24 year old patients exhibited the lowest scores) and geographical location (Northern Italy had the highest scores). CONCLUSION: CAT is a valid tool for measuring communication in surgical settings. PRACTICE IMPLICATIONS: Results suggest that expectations of young people for communication in surgical settings are not being met. While there is room to improve communication skills of surgeons across Italy, patients highlighted the greatest need in the Central and Southern regions.

BACKGROUND AND AIM: After the first Italian case of Covid-19, the Government imposed the complete closure of all areas involved by the spread of the virus to contain transmissions. There was a massive reorganization of Hospitals, a stop of all elective activities and a convertion of many hospitals in "Covid Centers''. AITOG (Associazione Italiana Traumatologia e Ortopedia Geriatrica) conducted a retrospective study on all proximal femur fractures surgeries that occurred in this period, to find out whether the pandemic and the correlated lockdown somehow changed the incidence of these events. Methods: 10 Italian orthopedic centers were involved in the study. Considering the geographic location, three groups were created (North, Centre and South). The considered period is the Italian "Phase 1" (February 23rd - May 3rd 2020). RESULTS: the cohort is composed of 412 patients, 116 male and 296 female (mean age 81.1 ± 9.1 years). The same period of 2019 has been used as control group, with 558 patients, 156 male and 402 female (mean age 84.2 ± 8.0 years). In 2020 we counted 323 (78.4%) fractures occurred at home, 61 (14.8%) in retirement houses and 28 (6.8%) in different locations. We mainly treated fractures with intramedullary nails (n.237 57.5%). Among all patients we had 46 (11.1%) Covid-19 positive. The mortality rate within 30 days was of 51 patients (12.4%); 23 of these died because of complications related to Covid-19 while 31 of these were in treatment with anticoagulant/antiaggregant. CONCLUSIONS: AITOG analysis demonstrates a decrease in surgical interventions for proximal femur fractures from 2019 to 2020, a reduction in patients mean age and an increase in trauma occurred in domestic environment. We also registered a consistent difference between the North, Center and South of the Country.

BACKGROUND AND AIMS: Diaphragmatic ruptures are associated with blunt abdominal or thoracic trauma and often occur in car and motorbike accident with a high energy impact. CASE PRESENTATION: We report two cases of patients victims of car and motorbike accidents that were referred to the Emergency Department of our Hospital in August and September 2017 for a politrauma. The patients were both diagnosed with a left diaphragmatic rupture with herniation of the stomach in the chest, and decomposed fractures of the ribs. One of the two patients reported a large abdominal wound with loss of substance in the site of the impact. Both patients underwent to open emergency surgery with primary repair of the phrenic rupture. The post-operative course was characterized by the occurrence of complications such as respiratory distress and emothorax for one of the patients. CONCLUSION: Traumatic rupture of the diaphragm can be associated to blunt or penetrating abdominal trauma in car and motorbike accident with a prevalence of the left-sided lesions. In patients with politrauma an associate rupture of the diaphragm should be always suspected especially in motor accident where high energy impact can generate a traumatic laceration of the respiratory muscle. The treatment of associate thoracic wall fractures to prevent weaning and respiratory distress in intubated patient should be discussed.

INTRODUCTION: The use of three-dimensional image reconstruction in liver surgery is well-known and has got many applications: It was first developed for vein reconstruction in liver transplantation and for liver volumetry to prevent post hepatectomy liver failure (PHLF) after major resections. There are many other advantages described in the literature provided by three-dimensional reconstruction, however its diffusion is currently limited. CLINICAL CASE: We present the case of a woman with a single colon cancer metastasis in segment 5 of the liver. Using CT scan images we created a three dimensional reconstruction of the patient's liver and its inners structures. The rendering was used to hypothesize the plan of dissection and to predict the pedicles that needed to be dissected during the procedure. DISCUSSION: We try to demonstrate that, thanks to three dimensional image reconstruction, all the structures that need to be dissected could be effectively located prior to the the surgery with a high grade of approximation. Furthermore the 3D reconstruction could be used as a step by step guide during the whole surgical procedure, showing all the pedicles To be encountered and dissected at every stage. CONCLUSION: 3d reconstruction of the liver is a valid aid in the interpretation of preoperative imaging and intraoperative ultrasound, both for the surgeon and for the entire equipe, facilitating comprehension of patient's liver anatomical features. It allows to predict the location and direction of the pedicles that need to be dissected and resected with high approximation, in order to achieve a more precise and tailored surgery.
RESUMO
BACKGROUND: SARS-CoV-2 infection has spread worldwide, and the pathogenic mechanism is still under investigation. The presence of a huge inflammatory response, defined as "cytokine storm," is being studied in order to understand what might be the prognostic factors implicated in the progression of the infection, with ferritin being one of such markers. The role of ferritin as a marker of inflammation is already known, and whether it changes differently between COVID and non-COVID patients still remains unclear. The aim of this retrospective analysis is to understand whether the inflammatory process in these two types is different. METHODS: In this retrospective analysis, we compared 17 patients affected by SARS-CoV-2, who had been admitted between February and April 2020 (group A) along with 30 patients admitted for acute surgical disease with SARS-CoV-2 negative swab (group B). A further subgroup of Covid negative patients with leukocytosis was compared to group A. RESULTS: In group A, the median (interquartile range) serum ferritin was 674 (1284) ng/mL, and it was double the cutoff (300 ng/mL) in 9 out of 17 (52%). The median (IQR) value of ferritin level in the total blood samples of group B was 231, and in the subgroup with leucocytosis, 149 (145). Group A showed a significantly higher ferritin median level compared to the entire group B (two-tailed Mann-Whitney test, p < 0.0001) as well as to the subgroup with leucocytosis (p < 0.0014). CONCLUSIONS: The role of iron metabolism appears to be directly involved in COVID infection. On the other hand, in the acute inflammation of patients admitted for surgery, and probably in other common phlogistic processes, iron modifications appear to be self-limited. However, our finding suggests the use of ferritin as a marker for COVID infection.
