RESUMO
BACKGROUND: The surgical management of concomitant occurrence of abdominal aortic aneurysm (AAA) and colorectal cancer (CRC) is still controversial. Conversely, benefits from a minimally invasive approach are well known concerning the treatment of both AAA and CRC. The aim of this study is to assess safety and feasibility of a sequential 2-staged minimally invasive during the same recovery by endovascular aneurysm repair (EVAR) technique and laparoscopic colorectal resection. METHODS: From January 2008 to December 2020, all patients with concomitant AAA and CRC were consecutively treated by EVAR and laparoscopic colorectal resection. Perioperative data were retrospectively collected in order to evaluate short- and long-term outcomes following the sequential 2-staged procedures. RESULTS: A total of 24 patients were included. The localization of the aneurysm was infrarenal abdominal aortic in 23 cases and in one case of common iliac artery. EVAR procedure has always been performed first. In 18 patients, a percutaneous access has been used while in 6 patients a surgical access has been adopted. Twelve patients had cancer in the left colon, 9 in the right colon, and 3 patients had rectal cancer. No conversions or intraoperative complications had occurred during laparoscopic surgery. The major complications rate after EVAR and CRC surgery was 8.3% and 12.5%, respectively. The mean interval between EVAR and CRC treatment was 7.8 ± 1 and the mean length of stay was 15.4 ± 3.6. No deaths occurred during hospitalization and between the procedures. Overall mortality was 20.8% with a mean follow-up of 39.41 ± 19.2 months. CONCLUSION: Elective sequential 2-staged minimally invasive treatment is a safe and feasible approach with acceptable morbidity and mortality rates and it should be adopted in current clinical practice to manage concomitant AAA and CRC.

BACKGROUND: The endovascular aneurysm repair (EVAR) is a successful treatment for aorto-iliac aneurysms. The success of EVAR is enhanced by the use of devices that maintain the patency of targeted arteries namely the iliac branch device (IBD) With this study we aimed to evaluate the association between the use of Jotec E-ventus during EVAR with IBD and prognosis in patients with aorto-iliac aneurysms. METHODS: This is a retrospective, multicentric study enrolling patients referred to our Vascular Surgery Units from January 2015 to January 2020. All patients underwent EVAR with IBD using Jotec E-ventus as bridging stent. Primary endpoint was the development of types I and III endoleaks. Secondary endpoint was the onset of device occlusion with loss of vascular patency. RESULTS: We studied 32 patients (mean age 71.7±4.5y). Of these, 25 patients were treated with standard EVAR procedure whereas 7 were treated with isolated IBD due to extension of disease involving iliac bifurcation. Median follow-up lasted 15[IQR11-27] months. During follow-up, incidence rates for endoleaks and occlusion were 3.98(95%CI 0.48-14.41) and 1.99(95%CI 0.05-11.12) per 100 pts/year. CONCLUSIONS: Jotec E-ventus during EVAR is associated with a low rate of severe complications in a small cohort of patients with aorto-iliac aneurysms.

BACKGROUND: Venous aneurysms are long-term complications of arteriovenous fistula (AVF) for hemodialysis with an estimated incidence rate of around 5-6%. The purpose of our study is to investigate the role of immunosuppressive therapy in the development of AVF aneurysms in renal transplant patients, and to determine whether AVF closure following transplantation is necessary. METHODS: Forty-six patients with symptomatic venous AVF aneurysms underwent ligation and resection of their fistulas between January 2013 and January 2020. Immunohistochemical expression of CD3, CD4, and CD8 was assessed on the surgical specimens to characterize lymphocytic infiltrate in the aneurysm wall. Patients were subdivided into "Group A"-kidney transplant patients undergoing immunosuppressive therapy which was comprised of 39 patients and "Group B"-patients who had not undergone kidney transplant which was comprised of 7 patients. The 2 groups did not significantly differ in age, sex nor risk factors for aneurysms. RESULTS: Group A showed a significantly higher aneurysm diameter (P < 0.0001), mean flow (P < 0.0001) and required a longer duration of surgery (P = 0.0007). A CD3+ lymphocytic infiltrate was significantly more common in Group A than in the Group B (90% vs 29%; P < 0.001). No significant differences in localization (adventitia, media or intima) and type (CD4+ vs CD8+) of lymphocytes were found between the 2 groups. CONCLUSION: AVF venous aneurysms were significantly larger and with a more intense T-lymphocytic infiltrate in patients undergoing immunosuppressive therapy. This finding suggests that immunosuppressive therapy plays a role in aneurysm formation, supporting the need for AVF closure in patients with an estimated low risk of rejection.

The benefit of balloon angioplasty, with or without stenting, for the treatment of patients with renal artery stenosis remains controversial. A number of randomized controlled trials have attempted to determine its efficacy but the matter remains unclear. A 2014 Cochrane review, which combined data from 8 trials, showed homogeneity among the trials with no significant benefit shown. This systematic review replicates the same research methods and meta-analysis while expanding it to include papers between 2014 and 2018. One of the trials included in the previous review published results in the interim. Additionally, 2 ongoing trials identified in the 2014 review are yet to publish any result. Meta-analysis of the reports showed no heterogeneity between trials and no significant improvement shown by balloon angioplasty, with or without stenting, versus medical therapy. Further studies are recommended in order to assess the benefits of balloon angioplasty for patients with more severe renal artery stenosis.

BACKGROUND: Ruptured mycotic aneurysms are an extremely rare complication of intravesical Bacillus Calmette-Guerin (BCG) immunotherapy. Several cases involving various arterial sites, mostly in the thoracic or abdominal aorta, have been described in the literature. BCG immunotherapy rarely causes false aneurysms and open surgical repair using an in situ prosthetic graft is most commonly performed. Further to this, targeted antituberculous treatment is required for at least one year following surgery. METHODS: A 69-year-old man presented at our clinic with fever, lower back pain and malaise. One year before admission he was treated, again, with intravesical BCG for recurrence of a carcinoma. RESULTS: A large infected pseudoaneurysm of 115mm was treated with the implantation of an aortouniiliac endoprosthesis followed by a crossover femoro-femoral bypass and surgical resection of the mass via an retroperitoneal approach. CONCLUSIONS: Endovascular repair can be considered a valid option in an emergency. A hybrid approach was chosen due to the need for urgent action and the poor condition of the patient who was haemodynamically unstable. In particular, the implantation of an aortouniiliac endoprosthesis at the level of the contralateral iliac axis allowed us to avoid the release of an endoprosthesis at the infected area level. Close patient follow-up with clinical evaluation every three months and a CT-scan yearlyis mandatory following the intervention and during antibiotic therapy. A systematic review of the literature has been subsequently carried out on this specific clinical case, highlighting 47 cases described from 1988.

BACKGROUND: During laparoscopic trans-abdominal pre-peritoneal hernia repair (TAPP) the positioning of the mesh around the spermatic cord could provide an additional anchoring point and ensure better defect closure, thereby preventing mesh movement and recurrence. The primary aim of our retrospective study was to determine if, during a TAPP procedure, an advantageous difference for mesh placement exists between the slit and the non-slit techniques in terms of recurrence rate. Secondary aims were intra and post-operative complications and the time required to return to normal activity. METHODS: From January 2010 to December 2015, data from patients who had undergone TAPPs at our Institution were prospectively collected. We performed a retrospective case control matched study of two homogenous (BMI, Age, type of hernia) groups of 100 patients who underwent respectively TAPP with no slit mesh placement (Group NS) and slit mesh placement (Group S). Statistical analysis was carried out using a SPSS 20. To compare continuous variables, an independent sample T-test was performed. A Chi-square test was employed for categorical data. RESULTS: No differences were found between the slit and non-slit groups in terms of biometric features and intra and post-operative outcomes were found to be similar in both groups as well. In particular, at mean follow-up of 57.34 ± 10.56 months for Group NS and 55.66 ± 8.61 months for Group S months only one recurrence per group was found. CONCLUSION: Our study failed to prove a superiority of the slit mesh technique over the no-slit mesh technique during TAPP. However, in light of its not being a randomized study, a subsequent, well-designed RCT would be desirable in order to better determine if the Slit mesh technique could prove to be advantageous enough to justify its routine use during the TAPP procedure.

BACKGROUND: Castleman's disease is a rare lymphoproliferative disorder of unknown etiology that most commonly presents as a mediastinal nodal mass. It is exceptionally uncommon for Castleman's disease to present in the mesentery and, only 53 cases have ever been described in the literature. Standard treatment for this lymphoproliferative disorder involving a single node is a complete "en bloc" surgical resection which has proven to be a curative approach in almost all cases without recurrence after 20 years of follow up. All 53 reported cases of mesenteric Castleman's disease, except one, were treated with laparotomy. CASE PRESENTATION: We report on a case of mesenteric Castleman's disease localized in the mesentery which is the second reported case if its kind and was treated by a laparoscopic-assisted procedure. Our female patient had an uneventful postoperative course and was discharged in the 5th post-operative day. No signs of recurrence were present as evidenced by physical examination and total body CT scan 24 months after the operation. We compare our case with the other reported cases in which Castleman's disease presented as an isolated mass in the abdomen. CONCLUSION: Although a rare disease, Unicentric Castleman's disease should always be considered when a solid asymptomatic abdominal mass is occasionally presented. The laparoscopic approach (LA) allows for the achievement of better results than open surgery, including a reduction in postoperative pain and length of hospital stay. In cases of masses of an uncertain nature, LA must be considered the last diagnostic tool and the first treatment one.

AIM: In this study, we proposed a peritoneal scintigraphy with a different marker, the 99mTechnetium-Icodextrin, to evaluate the distribution of the dialysate within the peritoneal cavity in peritoneal dialysis (PD) patients. METHODS: 99mTc-Icodextrin scintigraphy was performed in 16 PD patients. 0.5 ml of 7.5% Icodextrin solution was labeled with 74 megabecquerel (MBq) of 99mTc and then added to 2,000 ml of dialysate solution (2.5% dextrose). The peritoneum scintigraphy was performed by a SPECT gamma camera with the peritoneal cavity filled and after the complete drainage of the radio compound-dialysate mixture. The images were reviewed for evidence of peritoneal leaks, hernias, loculated fluid collections, and peritoneal membrane adhesions. RESULTS: Abnormal findings were detected by 99mTc-Icodextrin scintigraphy in 4 (25%) out of 16 patients and included retroperitoneal (n = 1), diaphragmatic (n = 1) and inguinal (n = 1) leakages and peritoneal membrane adhesions (n = 1). CONCLUSIONS: Peritoneum scintigraphy with 99mTc-Icodextrin is a useful method to detect some complications occurring during peritoneal dialysis; it offers excellent imaging to assess these complications.

AIMS: Our group investigated albumin gene expression in human adipocytes, its regulation by inflammation and the possible contribution of adipose tissue to albumin circulating levels. METHODS: Both inflamed and healthy subjects provided adipose tissue samples. RT-PCR, Real-Time PCR, and Western Blot analysis on homogenates of adipocytes and pre-adipocytes were performed. In sixty-three healthy subjects and fifty-four micro-inflamed end stage renal disease (ESRD) patients circulating levels of albumin were measured by nephelometry; all subjects were also evaluated for body composition, calculated from bioelectrical measurements and an thropometric data. RESULTS: A clear gene expression of albumin was showed in pre-adipocytes and, for the first time, in mature adipocytes. Albumin gene expression resulted significantly higher in pre-adipocytes than in adipocytes. No significant difference in albumin gene expression was showed between healthy controls and inflamed patients. A significant negative correlation was observed between albumin levels and fat mass in both healthy subjects and inflamed ESRD patients. CONCLUSIONS: In the present study we found first time evidence that human adipocytes express albumin. Our results also showed that systemic inflammation does not modulate albumin gene expression. The negative correlation between albumin and fat mass seems to exclude a significant contributing role of adipocyte in plasma albumin.

The aim of this systematic review is to identify patient-related, perioperative and technical risk factors for esophago-jejunal anastomotic leakage (EJAL) in patients undergoing total gastrectomy for gastric cancer (GC). A comprehensive literature search of PubMed/MEDLINE, Embase and Scopus databases was performed. Studies providing factors predictive of EJAL by uni- and multivariate analysis or an estimate of association between EJAL and related risk factors were included. All studies were assessed for methodological quality, and a narrative synthesis of the results was performed. A total of 16 studies were included in the systematic review, with a total of 42,489 patients who underwent gastrectomy with esophago-jejunal anastomosis. Age, BMI, impaired respiratory function, prognostic nutritional index (PNI), alcohol consumption, chronic renal failure, diabetes and mixed-type histology were identified as patient-related risk factors for EJAL at multivariate analysis. Likewise, among operative factors, laparoscopic approach, anastomosis type, additional organ resection, blood loss, intraoperative time and surgeon experience were found to be predictive factors for the development of EJAL. In clinical setting, we are able to identify several risk factors for EJAL. This can improve the recognition of higher-risk patients and their outcomes.
RESUMO
Indocyanine green (ICG) fluorescence imaging is widely used in abdominal surgery. The implementation of minimally invasive rectal surgery using new methods like robotics or a transanal approach required improvement of optical systems. In that setting, ICG fluorescence optimizes intraoperative vision of anatomical structures by improving blood and lymphatic flow. The purpose of this review was to summarize all potential applications of this upcoming technology in rectal cancer surgery. Each type of use has been separately addressed and the evidence was investigated. During rectal resection, ICG fluorescence angiography is mainly used to evaluate the perfusion of the colonic stump in order to reduce the risk of anastomotic leaks. In addition, ICG fluorescence imaging allows easy visualization of organs such as the ureter or urethra to protect them from injury. This intraoperative technology is a valuable tool for conducting lymph node dissection along the iliac lymphatic chain or to better identifying the rectal dissection planes when a transanal approach is performed. This is an overview of the applications of ICG fluorescence imaging in current surgical practice and a synthesis of the results obtained from the literature. Although further studies are need to investigate the real clinical benefits, these findings may enhance use of ICG fluorescence in current clinical practice and stimulate future research on new applications.

Chronic kidney disease (CKD) is a clinical condition characterized by high morbidity and mortality. Globally, CKD is also increasing in prevalence and incidence. The two principal kidney measures namely estimated glomerular filtration rate (eGFR) and albuminuria have been found to be predictors of renal and cardiovascular (CV) endpoints including peripheral artery disease (PAD). The prevalence of PAD was increased in CKD patients and, particularly, in patients with more severe CKD stages. Despite the fact that revascularization strategies are suitable in CKD patients in similar fashion to non-CKD patients, few CKD patients underwent these procedures. In fact, if it is true that revascularization improves prognosis in PAD patients irrespective of baseline eGFR, it was also demonstrated that CKD patients, who underwent revascularization, were at higher risk for amputations, mortality, re-intervention and perioperative complications. With the present review article, we have examined the association between CKD, PAD and peripheral revascularization highlighting data about epidemiology, pathophysiologic mechanisms, and results from previous observational and intervention studies. We have also examined the future perspectives and challenges of research around the association between CKD and PAD.
RESUMO
BACKGROUND: Inguinal hernia (IH) is a major problem in general surgery and its prevalence is increasing. The presence of hernias has been associated with a wide spectrum of venous diseases, with the involvement of imbalances in collagen and extracellular matrix deposition and metalloproteinases dysfunction. We aimed to evaluate whether the association between IH and vascular diseases is also present with respect to arterial diseases. METHODS: We designed a cross-sectional observational study enrolling consecutive patients undergoing surgical repair of IH. Arterial diseases (AD) considered were carotid stenosis, peripheral artery disease and abdominal aortic aneurysms. RESULTS: Study population consisted of 70 patients. Mean age was 63.2 ± 4.7 years. Prevalence of AD was 42.9% in the whole cohort. AD patients were older (p = 0.015), and more frequently had hypertension (p = 0.001) and active smoking habits (p = 0.001) than the no-AD group. Albumin-to-creatinine ratio (ACR) was higher in AD than in no-AD patients (p < 0.001). At multivariable analysis, increased ACR (odds ratio, OR: 1.14, p < 0.001), old age (OR: 1.25, p = 0.001) and a smoking habit (OR: 3.20, p = 0.001) were significant correlates for the presence of AD. CONCLUSIONS: Prevalence of AD in patients with IH is non-negligible. Old age, a smoking habit and an abnormal excretion of urine albumin are associated with the presence of AD in these patients. Future studies are needed to gain more insights into the pathogenic mechanisms underlying this association, exploring also the specific role of metalloproteinases.
RESUMO
Ancient Schwannoma is a type of peripheral neurogenic tumor formed by the Schwann cells presenting mainly as a benign and asymptomatic lesion. The neurilemmoma tumor appears in different sites and, in cases of cervical location, can mimic a carotid body tumor. Herein we describe a clinical case of a 51-year-old woman with latero-cervical swelling. A contrast-enhanced computed tomography scan revealed a classical wineglass image mimicking a carotid body tumor. During surgery the tumor appeared connected to the cervical sympathetic trunk without carotid involvement. The histological exam confirmed the nature of the mass which consisted of an ancient schwannoma. A subsequent systematic review of the literature on ancient schwannoma incidence and treatment confirms it being a benign and rare lesion primarily treatable with open surgery. KEY WORDS: Ancient Schwannoma, Carotid body tumor, Carotid artery, Vascular surgery.

BACKGROUND: Bladder cancer is the eleventh most commonly diagnosed cancer worldwide. The recurrence rate of this cancer can be very high, up to 45%. Photodynamic diagnosis (PDD) is more sensitive than standard procedures for the detection of malignant tumours. The aim of the study was to evaluate oncological outcomes in white light TURB (WL-TURB) and hexaminolevuninate blue light TURB (Hal-TURB). PATIENTS AND METHODS: This was a retrospective longitudinal single-center study. In the period between January 2016 and October 2016 WL-TURB was the only therapeutic option available. From November 2016 until April 2017 all TURBs were fluorescence-guided (Hal-TURB). Kaplan-Meier curves have been used to estimate recurrence free survival rates. RESULTS: One hundred and eleven patients underwent Hal- TURB and 137 underwent WL-TURB. Recurrence rate after 12 months was 19.8% (22 out of 111 patients) and 37.2% (51 out of 137 patients) in HAL-group and WL-group respectively (p < 0.01). The recurrence-free period was longer in HAL-group rather than WL-group (8.9 months vs 7.3 months, p < 0.05). Moreover, the recurrence rate during the first 6 months was 3.7% in patients who underwent HAL-TURB and 16% in those who received WL-TURB (p < 0.01). CONCLUSION: The results of the study show that recurrence-free survival was longer in patients undergoing HAL-TURB compared to the patients who received standard WL-TURB.

Leiomyoma of the bladder is a very rare disorder that accounts for 0.43% of all bladder neoplasms. Although the pathophysiology of the bladder leiomyoma is unknown, there are some theories on it. The patients can be asymptomatic; when present, clinical symptoms (lower urinary tract symptoms and\or hematuria), are associated with tumor size and location. For diagnosis, imaging plays an important role: ultrasound, computed tomography (CT) scan and magnetic resonance imaging (MRI) are the examinations most frequently performed. Treatment consists of surgical removal of the tumor, and the prognosis is excellent.

BACKGROUND: Crohn's disease (CD) is a chronic inflammatory bowel disease frequently associated with malabsorption and secondary protein-energy malnutrition (PEM). METHODS: Biochemical and clinical data of 63 (34 females, 29 males) patients with PEM due to CD sent to our outpatient unit for nutritional evaluation were retrospectively analyzed. Patients were divided into two groups, according to disease activity. Thirty-eight patients (group A) had the active disease, and 25 patients (group B) suffered from malabsorption resulting from past intestinal resections due to CD. After a physical and hemato-biochemical evaluation at the first visit, all patients received disease-specific personalized dietetic indications. When indicated, oral nutritional supplements, oral/parenteral vitamins, micronutrients, and electrolytes, up to parenteral nutrition, were prescribed. RESULTS: After 1, 3, and 6 months of nutritional therapy, body weight, body mass index (BMI), and serum butyryl-cholinesterase significantly improved in both groups. In 8 out of 13 (61.5%) patients with a cutaneous stoma, intestinal continuity was restored. CONCLUSIONS: This study confirms the effectiveness of nutritional rehabilitation and provides information on the time required for nutritional treatment in patients with CD, both during the acute phase and after malabsorption due to intestinal resection.

Every colorectal surgeon during his or her career is faced with anastomotic leakage (AL); one of the most dreaded complications following any type of gastrointestinal anastomosis due to increased risk of morbidity, mortality, overall impact on functional and oncologic outcome and drainage on hospital resources. In order to understand and give an overview of the AL risk factors in laparoscopic colorectal surgery, we carried out a careful review of the existing literature on this topic and found several different definitions of AL which leads us to believe that the lack of a consensual, standard definition can partly explain the considerable variations in reported rates of AL in clinical studies. Colorectal leak rates have been found to vary depending on the anatomic location of the anastomosis with reported incidence rates ranging from 0 to 20%, while the laparoscopic approach to colorectal resections has not yet been associated with a significant reduction in AL incidence. As well, numerous risk factors, though identified, lack unanimous recognition amongst researchers. For example, the majority of papers describe the risk factors for left-sided anastomosis, the principal risk being male sex and lower anastomosis, while little data exists defining AL risk factors in a right colectomy. Also, gut microbioma is gaining an emerging role as potential risk factor for leakage.

INTRODUCTION: The presence of pre-existing abdominal wall defect (AWD) could represent a potential contraindication for peritoneal dialysis (PD) treatment. We report the results of our 6-year experience involving simultaneous repair of pre-existing AWD and catheter insertion for PD. METHODS: Patients with estimated glomerular filtration rate (e-GFR) 7-10 ml/min attending a single nephrology clinic between January 2008 and December 2014 were evaluated. Simultaneous AWD repair and catheter placement was performed. For inguinal (IH) or umbilical hernia (UH), a prolene mesh repair technique was adopted. Except for one case of total anaesthesia, the surgical procedure was performed under either spinal or local anaesthesia. Ceftazidime alone or in association with quinolones was administered 1 h before surgery in a single dose. Patients were discharged 2 days after surgery, and returned to the clinic twice during the 1st week for peritoneum washing (first volume of peritoneal dialysis solution: 300 ml). From week 3, volume (2000 ml) and dwells were personalized according to the patient's clinical condition; options were: incremental PD, standard PD, or continuous cycling PD. Surgical follow-up was planned at 1, 6, and 12 months. RESULTS: Peritoneal catheters were inserted in 170 patients. IH, UH and incisional hernia were found in 18, 2 and 1 patients, respectively. IH was bilateral in 4 patients; concomitant IH and UH occurred in 1 patient. There were no deaths, nor intra-operative complications apart from scrotal haematoma in 1 patient. Over a mean follow-up of 551 days (range 342-1274) no hernia recurrence was registered and the peritoneal catheter continued functioning without problems. CONCLUSIONS: Simultaneous AWD repair and peritoneal catheter placement seems a reliable and safe surgical procedure that allows patients with AWD to benefit from PD treatment.

We describe the case of a 72-year-old man with massive hemorrhage and shock resulting from rupture of the left common femoral artery as a complication of radiotherapy in the groin for cancer of the scrotum. This complication is extremely rare, presents dramatically, and is usually fatal. The patient was successfully treated with a stent graft deployment in order to achieve immediate hemostasis maintaining blood flow to the leg. Open surgery is not ideal in those cases especially when there is extensive tumor involvement of the groin causing altered anatomy and increasing the risk of re-bleeding.
