Background Fluid effusion (blood, lymph, or urine) in kidney transplantation may give rise to several complications, directly, such as hematoma, seroma, lymphocele, and/or urinoma, or consequently, such as increased infection risk, longer hospital stay, graft compression—with or without functional impairment—and necessity of further hospitalizations. The aim of this study was to evaluate effectiveness of hemostatic biomaterials in prevention of fluid effusions, especially lymphocele in kidney transplant patients. Methods We selected 40 patients who underwent kidney transplantation from 2009 to 2012 in which we used hemostatic biomaterials, and compared their results with those of other transplant patients from our center in which we did not used these biomaterials. Evaluated parameters were: fluid effusion, graft function, quality and quantity of drainage, blood count, and operative time. Results There was no difference in operative time. The incidence of complications on which biomaterials can have a role decreased; particularly, we observed a reduction from 24.21% to 7.5% of fluid effusions (lymphocele). There was no evidence of complications due to biomaterials. Conclusions Hemostasis is important in surgery, and in kidney transplantations lymphostasis also has a significant role. In addition to the traditional hemostatic methods, recently some biomaterials, with the purpose of providing atraumatic hemostasis, were added. In our experience they are easy to use, and their use has proved to be effective for both hemostasis and lymphostasis with consequent reduction of fluid effusions. [ABSTRACT FROM AUTHOR]

Background Considerable suffering is experienced by carers of patients with dementia. Most existing studies do not consider the coexistence of subjective and objective aspects that cause, interacting to each other, this suffering. Objectives In this study we: (1) define the high-risk group of caregivers on the bases of the scores obtained on the four scales evaluating burden, distress, depression and anxiety (BDDA) taken into account simultaneously and (2) evaluate risk factors related to the high level of BDDA. Subjects and methods 419 elderly outpatients with dementia and their caregivers were enrolled. Patients were evaluated for their cognitive, neuropsychological and functional impairment and for comorbidity. Caregivers were evaluated with four scales for the assessment of burden, distress related to neuropsychological disturbances, depression and anxiety. Cluster analysis was used to identify the group with the High level of BDDA (HBDDA). Results By multiple logistic analysis, disability, specific behavioural disturbances of the patients as well as caregiver's age, type of relationship and living in the south of Italy were observed to be a major risk factor for HBDDA. Conclusion The targeted use of scales specifically assessing BDDA of the caregiver and the identification of particular patient and caregiver characteristics are able to allow a precise and early definition of caregivers at high risk of burden and distress. This might be helpful in planning the correct social/clinical/rehabilitative approach. Copyright © 2005 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

An abstract of the research paper "Preliminary results with Habib's procedure," presented at the 13th annual meeting of the Italian Society of Geriatric Surgery, held in Lecce, Italy during December 2-4, 2010, is presented.

Abstract Background Patients on peritoneal dialysis treatment represent 15% of the global dialysis population. The major complication of peritoneal dialysis is catheter and peritoneal infection. Peritoneal dialysis patients who receive kidney transplants are at increased risk of infection because of immunosuppressive therapy. Aim The purpose of this study is to show our ideal timing to remove peritoneal catheter after kidney transplant, which gives adequate security on renal function recovery and reduction of septic risk. Method of Study We analyzed the outcomes of 65 patients on peritoneal dialysis who underwent kidney transplant between 2000 and 2016. Results In 61 cases there was an immediate graft functional recovery. In 4 cases there was a delayed graft function (DGF), and we performed a hemodialysis with temporary placement of a venous catheter. In all patients we removed peritoneal dialysis catheter 30 to 45 days after transplant. There has been 1 case of catheter infection, which was treated with antibiotic therapy. Discussion Our average time to remove the peritoneal dialysis catheter was shorter than times in previous studies, between the 30th and 45th postoperative day. In the 4 cases in which there has been a DGF, we performed hemodialysis treatment to avoid, in the immediate postoperative period, direct insults to the peritoneum by local dialysis procedures. Conclusion Our experience show that the 30th to 45th postoperative day is a good time frame, better yet a good watershed between the safe removal of peritoneal catheter when patients have a stabilized renal function and the possibility of leaving it in situ, to resume peritoneal dialysis in case of persistent DGF. Highlights • Transplanted patients under peritoneal dialysis are at increased risk of infection. • We aim to show our "ideal timing" to remove peritoneal catheter after transplant. • In all patients we removed peritoneal dialysis catheter 30-45 days after transplant. • In our experience 30th-45th postoperative days is a good timeframe for its removal.

Background: More than 50% of patients with colorectal cancer (CRC) present or develop hepatic metastases (HM). The intraoperative use of the Habib 4X ® radio frequency probe device is safe in resetting HM and allows a one-stage resection of both CRC and HM with a similar mortality rate than a two-stage surgical treatment., Methods: After an exhaustive residential training at the reference center for hepato-biliary surgery of the Imperial College of London, we treated at our unit of general surgery 40 consecutive patients with CRC and HM with the one-stage resection, using the Habib 4X ® intraoperative radiofrequency probe device to reset HM., Results: None of the 40 patients died during the intra-operatory and post-operatory periods, none presented liver failures during the postoperative course nor complication related to the Habib's resection procedure (e.g. bleeding, abscess, bile leak). The amount of intra-operative liver bleeding was minimal. New HM arose in 10 (25%) cases, with a mean disease-free interval of 13 months, but the hepatic tissue close to previous resections remained cancer-free. The 69.7% of patients were disease-free at month 24 of the post-operative follow-up and 5-year rate was about 70%., Conclusions: The data suggest that surgeons well trained at a reference center for hepato-biliary surgery may perform with excellent results the one-stage CRC and HM resection with the Habib 4X ® device even in a Unit of general surgery.

Following the COVID-19 epidemic outbreak in Ariano Irpino, Campania region (Italy), we tested lactating cows for the presence of SARS-CoV-2 on a cattle farm at which, prior to the investigation, 13 of the 20 farmworkers showed COVID-19-like symptoms, and one of them died. Twenty-four lactating cows were sampled to detect SARS-CoV-2. All nasal and rectal swabs and milk samples were negative for SARS-CoV-2 RNA. Of the 24 collected serum samples, 11 showed antibodies against SARS-CoV-2 nucleocapsid protein, 14 showed antibodies against SARS-CoV-2 spike protein, and 13 developed neutralising antibodies for SARS-COV-2; all samples were negative for Bovine Coronavirus (BCoV), another betacoronavirus. To our knowledge, this is the first report of natural serological evidence of SARS-CoV-2 infection in lactating cows. We hypothesise that this may be a case of reverse zoonosis. However, the role of cattle in SARS-CoV-2 infection and transmission seems to be negligible.

Background: Kidney transplantation (KT) is the gold standard for treatment of patients with end-stage-renal disease. To expand the donor reserve, it is necessary to use marginal/suboptimal kidneys., Methods: We retrospectively evaluated the short/long-term outcome of 34 KT elderly patients who received allografts with vascular abnormalities (MRA group), in comparison with 34 KT patients who received a kidney with a single renal artery (SRA group) pair-matched by age, length of time on dialysis, comorbidity and donor age., Results: All participants completed the International Physical Activity Questionnaire at KT, and then 4, 8, and 12 weeks after transplantation. Our data indicate that kidney with vascular anatomical variants may be successfully transplanted, since the overall rate of surgical complications was 20.6% in the SRA group and 17.6% in the MRA group and that the 5-year survival rate after KT was 100% in both groups., Conclusions: The data also underlined that individualized physical activity programs induced similar excellent results in both groups, improving physical capacities, arterial pressure, lipid metabolism, insulin sensitivity, quality of life and physical and mental status.

Primary angiosarcoma (AS) of the breast is an extremely unusual variant of breast malignancies, and its incidence is about 0.05% of all primary breast tumors. In this article, we present a rare case of a primary AS that developed in a young woman with breast implants. This case report emphasizes importance of early investigation for accurate diagnosis and proper management of the breast AS, along with a correlation of histopathologic, radiologic, and clinical findings.

Introduction: SARS-CoV-2 is a virus that causes a potentially deadly syndrome that affects especially the respiratory tract. Kidney-transplanted patients are immunosuppressed and more susceptible to viral infections. We have examined our transplantation activity to explore the future role of kidney transplantation from deceased and living donors in COVID-19 era. Patients and Methods . The activity of our transplant center of Naples (one of the two transplant centers in Campania, South Italy) continued during the COVID-19 pandemic. We have analysed the kidney transplants carried out between March 9 and June 9, 2020, comparing these data with the numbers of procedures performed in the two previous years. Moreover, we have considered the possibility of performing living donor transplants during a worldwide pandemic., Results: From March 9, 2020, when the Italian lockdown begun, till June 9, 2020, five kidney transplants have been performed at our transplant center in Naples, all from deceased donors. The donors and the recipients have been screened for COVID-19 infection, and the patients, all asymptomatic, followed strict preventive measures and were fully informed about the risks of surgery and immunosuppression during a pandemic. All the transplanted patients remained COVID negative during the follow-up. The number of transplants performed has been constant compared to the same months of 2018 and 2019. In agreement with the patients, we decided to postpone living donor transplants to a period of greater control of the SARS-CoV-2 spread in Italy., Conclusion: Deceased donor kidney transplantation should continue, especially in a region with moderate risk, like Campania, with a more careful selection of donors and recipients, preferring standard donors and recipients without severe comorbidities. Living donor transplantation program, instead, should be postponed to a period of greater control of the SARS-CoV-2 spread, as it is an elective surgery and its delay does not determine additional risks for patients., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this article., (Copyright © 2020 Gaia Peluso et al.)

Kidney transplantation is the surgical operation by which one of the two original kidneys is replaced with another healthy one donated by a compatible individual. In most cases, donors are recently deceased. There is the possibility of withdrawing a kidney from a consenting living subject. Usually, living donors are direct family members, but they could be volunteers completely unrelated to the recipient. A much-feared complication in case of kidney transplantation is the appearance of infections. These tend to arise due to immune-suppressor drugs administered as anti-rejection therapy. In this review, we describe the gastrointestinal complications that can occur in subjects undergoing renal transplantation associated with secondary pathogenic microorganisms or due to mechanical injury during surgery or to metabolic or organic toxicity correlated to anti-rejection therapy. Some of these complications may compromise the quality of life or pose a significant risk of mortality; fortunately, many of them can be prevented and treated without the stopping the immunosuppression, thus avoiding the patient being exposed to the risk of rejection episodes., Competing Interests: Conflict of interest: All the authors of the manuscript declare no conflict of interest in connection with this article., (© 2020 Armando Calogero et al., published by De Gruyter.)

Introduction: Wound complication frequently arises after kidney transplantation and its risk factors are well known. In a previous paper we analyzed these factors, and in this new retrospective study we evaluate the influence of lymphocele in the development of wound complications., Patients and Methods: From January 2000 to December 2018, 731 consecutive kidney transplants have been performed in our center. We have analyzed the incidence of wound complication and lymphocele and their risk factors., Results: Out of 731 kidney transplants, we have observed wound complications in 115 patients (15.7%) and lymphocele in 158 patients (21.7%). Of these, 70 patients developed both complications (9.5%), but 6 patients have been excluded because they were in therapy with mammalian target of rapamycin inhibitors. Twenty-nine patients (45.3%) presented a first level and 35 patients (54.7%) showed second level wound complications. Lymphocele was the only present factor in just 3 cases (4.6%). The other patients showed diabetes in 28 cases (43.7%), overweight/obesity in 38 (59.3%), delayed graft function in 17 (26.5%), and 60 years or more in 38 (57.8%). The association has been found in 30 out 64 patients treated with tacrolimus (46.8%) and in 34 with cyclosporine (53.1%); 40 patients did not receive muscular layer's reconstruction (62.5%)., Conclusion: Our experience shows that lymphocele alone is not a predisposing factor for wound dehiscence after kidney transplantation, and they often coexist because they share the same risk factors, the most important being obesity, diabetes and delayed graft function, older age, and surgical techniques. No relation has been observed with calcineurin inhibitor therapy., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Neoadjuvant chemoradiotherapy has a significant role in downstaging cancer. It improves the local control of the disease and can make conservative resection of rectal cancer possible., Methods: We enrolled 114 patients with subperitoneal rectal cancer who underwent neoadjuvant chemoradio-therapy and radical excision with total mesorectal excision (TME). The primary endpoint was oncological outcomes and the secondary endpoint was surgical outcomes.We evaluate the experience of a multidisciplinary team and the role of neoadjuvant chemoradiotherapy in integrated treatment of cancer of the subperitoneal rectum., Results: Surgical procedures performed were abdominal perineal resection in 4 cases (3.5%), anterior resection in 89 cases (78%), Hartmann's procedure in 5 cases (4.4%), and ultralow resection with coloanal anastomosis and diverting stoma in 16 patients (14%).Local recurrence occurred in 6 patients (5.2%), the overall survival was 71.9% at 5 years and disease-free survival was about 60%., Conclusions: The effect of pathological downstaging amounted to 58.8%, including cPR. The pathologic complete remission occurred in 8.8% of cases.The outcomes of neoadjuvant therapy can be achieved when this treatment is associated with correct surgical technique with TME and the prognosis is defined by an anatomopathological examination performed according to Quirke's protocol., Competing Interests: Conflict of interest: The authors have no conflicts of interest (political, personal, religious, ideological, academic, intellectual, commercial or any other) to declare in relation to this manuscript.

Background: There is currently no standard treatment for desmoid tumors (DTs) associated with familial polyposis coli (FAP). Familial adenomatous polyposis in DT patients is sometimes a life-threatening condition., Methods: We enrolled all consecutive patients with FAP treated at Unit of General Surgery and Transplant, University of Naples Federico II and evaluated the incidence of DTs on FAP between 1996 and 2016., Results: We observed 45 consecutive patients with FAP; of these 5 were DT-FAP-associated. All 5 cases with FAP were young women, age 25 to 65 years, previously treated by colectomy. Of these, 4 patients presented a parietal localization and had been treated with a wide surgical exeresis; one patient had an intra-abdominal, mesenteric tumor that was unresectable at laparotomy. We performed CT-guided drainage, ureteral stenting, medical therapy (sulindac+tamoxifene), and chemotherapy (dacarba-zine+doxorubicine).All patients were alive and underwent follow-ups for 5 years post-surgery; only 1 patient with parietal localization showed a local relapse after 2 years., Conclusions: We propose a modulated approach to the single patient with FAP, with surgery as treatment of choice for parietal localization disease and integrating different kinds of therapies (surgery alone or associated with RT, CT) for the intra-abdominal tumor., Competing Interests: Competing interests: The authors declare that they have no competing interests.

Aims: We aimed to summarize available lines of evidence about intraoperative and postoperative donor outcomes following robotic-assisted laparoscopic donor nephrectomy (RALDN) as well as outcomes of graft and recipients., Methods: A systematic review of PubMed/Medline, ISI Web of Knowledge, and Scopus databases was performed in May 2018. The following search terms were combined: nephrectomy, robotic, and living donor. We included full papers that met the following criteria: original research; English language; human studies; enrolling patients undergoing RALDN., Results: Eighteen studies involving 910 patients were included in the final analysis. Mean overall operative and warm ischemia times ranged from 139 to 306 minutes and from 1.5 to 5.8 minutes, respectively. Mean estimated blood loss varied from 30 to 146 mL and the incidence of intraoperative complications ranged from 0% to 6.7%. Conversion rate varied from 0% to 5%. The mean hospital length of stay varied from 1 to 5.8 days and incidence of early postoperative complications varied from 0% to 15.7%. No donor mortality was observed. The incidence of delayed graft function was reported in 7 cases. The one- and 10-year graft loss rates were 1% and 22%, respectively., Conclusions: Based on preliminary data, RALDN appears as a safe and effective procedure.

Temperature mapping is a key asset in supporting the clinician during thermal ablation (TA) treatment of tumors without adding additional risk to the TA procedure. Herein we report our experiments on multidimensional thermal mapping during radio frequency (RF) thermal ablation treatments of an ex-vivo animal organ. The temperature was monitored using several arrays of fiber Bragg gratings properly positioned around the RF applicator. The results show the effectiveness of our proposed method at assessing the TA probe depth and demonstrating how the insertion depth directly influences the maximum temperature and the treated area of the radio frequency ablation., Competing Interests: The authors declare that there are no conflicts of interest related to this article.

Background: There are not guidelines for surgical management of malignant bowel obstruction (MBO) caused by peritoneal carcinomatosis (PC), mainly when it involves elderly; so its treatment is still debated., Aim: To outline indications and benefits of palliative surgery for obstructive carcinomatosis and determine what prognostic factors, including age, have independent and significant association with outcome., Methods: We conducted English-language MEDLINE and EMBASE searches of articles published between 1998 and 2016, which reported outcome data after palliative surgery for MBO due to PC. We excluded all articles lacking of surgical cohort and those with main interest in conservative treatment. Of 1275 articles identified, 12 satisfied selection criteria and were included in our analysis., Results: Overall, these studies involved 548 patients undergoing palliative surgery for MBO caused by PC. The median age was 58 (range 19-93). Relief of symptoms was achieved in 26.5-100% of cases. Postoperative morbidity ranged between 7 and 44%. Mortality was high (6-22%). The median survival was longer in surgical patients than in those receiving conservative therapy (8-34 vs 4-5 weeks). Factors associated with surgery failure were poor performance status, diffuse carcinomatosis, previous radiotherapy, and obstruction of small bowel. Old age was significantly associated with a poor prognosis upon univariate analysis, while this association vanished upon multivariate analysis., Conclusions: Surgical palliation can provide relief of obstructive symptoms as well as improved survival in well-selected patients, even if elderly.

Introduction: Gastric cancer is the fifth most common cancer and the third cause of cancer death. The clinical outcomes of the patients are still not encouraging with a low rate of 5 years' survival. Often the disease is diagnosed at advanced stages and this obviously negatively affects patients outcomes. A deep understanding of molecular basis of gastric cancer can lead to the identification of diagnostic, predictive, prognostic, and therapeutic biomarkers., Main Body: This paper aims to give a global view on the molecular classification and mechanisms involved in the development of the tumour and on the biomarkers for gastric cancer. We discuss the role of E-cadherin, HER2, fibroblast growth factor receptor (FGFR), MET, human epidermal growth factor receptor (EGFR), hepatocyte growth factor receptor (HGFR), mammalian target of rapamycin (mTOR), microsatellite instability (MSI), PD-L1, and TP53. We have also considered in this manuscript new emerging biomarkers as matrix metalloproteases (MMPs), microRNAs, and long noncoding RNAs (lncRNAs)., Conclusions: Identifying and validating diagnostic, prognostic, predictive, and therapeutic biomarkers will have a huge impact on patients outcomes as they will allow early detection of tumours and also guide the choice of a targeted therapy based on specific molecular features of the cancer.

Background: Colorectal cancer (CRC) is one of the most spread neoplasia types all around the world, especially in western areas. It evolves from precancerous lesions and adenomatous polyps, through successive genetic and epigenetic mutations. Numerous risk factors intervene in its development and they are either environmental or genetic., Aim of the Review: Alongside common screening techniques, such as fecal screening tests, endoscopic evaluation, and CT-colonography, we have identified the most important and useful biomarkers and we have analyzed their role in the diagnosis, prevention, and prognosis of CRC., Conclusion: Biomarkers can become an important tool in the diagnostic and therapeutic process for CRC. But further studies are needed to identify a noninvasive, cost-effective, and highly sensible and specific screening test for their detection and to standardize their use in clinical practice.

We report on the integration of fiber optic sensors with commercial medical instrumentation for temperature monitoring during radio frequency ablation for tumor treatment. A suitable configuration with five fiber Bragg grating sensors bonded to a bipolar radio frequency (RF) probe has been developed to monitor the area under treatment. A series of experiments were conducted on

Background and Aim: Ideally, day-surgery laparoscopic cholecystectomy (DLC) combines patient satisfaction with cost-effectiveness. However, DLC has not yet been widely applied in the elderly. Thus, to challenge the current perception of DLC as a contraindication, several parameters were investigated for the feasibility of DLC within the general and elderly population. A retrospective study was conducted to analyse age, along with other relevant patient characteristics, as factors leading to successful 24-h discharge., Methods: Data were collected from 207 patients who underwent laparoscopic cholecystectomy (LC) between 2010 and 2013. Of these patients, 154 were aged <75 years and 53 > 75 years, with a median age of 59.3 years. Comparisons of the length of post-surgical hospital stay were made. Further, the parameters influencing the surgeon's decision to discharge patients within a 24-h period were investigated: demographic data; patient characteristics such as age, sex and concomitant diseases; disease presentation; surgical experience; intraoperative complications; and post-operative course. The numbers of hospital readmissions and reoperations were established as parameters of failure., Results: Forty-five (21.7%) patients remained hospitalized up to 24 h. The majority of them had no co-morbidities, low American Society of Anesthesiologists (ASA) grades, adenomas and uncomplicated gallstone disease. Eleven patients were aged >75 years. None of the patients died, whereas one patient was readmitted following DLC., Considerations: Age itself did not prove to be a contraindication for DLC. The patient's general health, disease presentation and the surgeon's attitude were the main factors favouring early discharge. Patient selection and patient-care facilities were crucial for successful outcomes. Some problems due to the logistical organization of the hospital and the surgical approach, which may impede DLC acceptance, are described herein., (Copyright © 2016 IJS Publishing Group Ltd.

Conventional pancreatic resections for pancreatic neck and body diseases include pancreaticoduodenectomy, distal pancreatectomy with or without splenectomy, and total pancreatectomy. Recent studies have reported encouraging results of non-traditional pancreatic resections, including central pancreatectomy (CP), for central pancreatic disease. This surgical approach offers the potentials of low postoperative morbidity and preservation of metabolic functions. This study performs a systematic review on CP. A comprehensive literature search was conducted, for the period 1992-2015, on three worldwide databases: PubMed, Scopus, ISI-Web of Knowledge. We focused on indications, morbidity and mortality of this surgical procedure. The review shows that CP is particularly suitable for small-medium size diseases localized into the pancreatic body. This procedure is associated with an increased postoperative morbidity but an excellent postoperative pancreatic function. CP is a safe and effective procedure when performed following the right indications., (Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.)

Introduction: Complete abdominal wall infiltration with neoplastic gastrocutaneous fistula is an unexpected and out of the ordinary presentation of locally advanced gastric cancer. It is very rare to encounter case reports presenting diffuse abdominal wall invasion, but a complete parietal destruction is an exceptional event., Case Presentation: Here we describe the case of an 81-year-old Caucasian woman presenting a carcinoma perforating her anterior gastric wall and infiltrating all layers of her abdominal wall. The gastric tumor infiltrated her transverse mesocolon, the rectus abdominis muscles bilaterally and overran them anteriorly, causing a large parietal deficit and a complete external fistula. Treatment consisted of a complex surgical procedure requiring general and reconstructive surgery cooperation in order to perform an en bloc gastric resection including colon and abdominal wall, followed by a parietal reconstruction through positioning of prosthesis and reverse abdominoplasty., Conclusions: Clinical presentation, histology and therapeutic options are discussed. The importance of a multidisciplinary approach when encountering extremely rare clinical presentations is emphasized.

Immunodeficiency is associated with higher cancer incidence. However, it is unknown whether there is a link between immunodeficiency and development of multiple primary malignancies. In the present study we analyse this link focusing on kidney-transplanted patients, as they are at higher risk of developing cancer due to the chronic assumption of immunosuppressants. We followed up 1200 patients who underwent kidney transplantation between 1980 and 2012. A total of 77/1200 kidney-transplanted patients developed cancer and 24 of them developed multiple cancers. Most multiple cancers were synchronous with a nonsignificant association between cancer and rejection episodes. In the general cancer population, one-ninth of patients are at higher risk of developing a second tumor over a lifetime; hence it would be reasonable to conclude that, from a merely theoretical and statistical viewpoint, long-term transplanted patients potentially have a higher risk of developing MPMs. However, data did not confirm this assumption, probably because these patients die before a second primary malignancy appears. Despite many observations on the increased incidence of different tumor types in immunodeficient patients and despite immunosuppression certainly being a predisposing factor for the multicancer syndrome, data so far are not robust enough to justify a correlation between immunodeficiency and multiple primary malignancies in transplanted patients.

Aim: Pseudoaneurysm (PA) at the anastomosis site in kidney transplantation is a rare but serious complication that usually requires graft nephrectomy. Literature reports are sporadic and usually focused on limb rather than graft salvage. In this paper we focus on this last point., Material of Study: 6 patients presenting large PA at the anastomosis between iliac and graft artery were identified in our series. The diagnosis was performed with US, AngioTC scan and angiography. Blood cultures and labeled leukocyte scintigraphy were also performed. All patients underwent open surgery., Results: Transplant nephrectomy was needed in all cases except one, in which it was possible to perform a graft replanting on hypogastric artery. Our perioperative mortality and morbidity rate was recorded., Discussion: Etiology of PA is multifactorial, however an association with chronic rejection or infection must be also considered. Our mortality and morbidity rates are in accordance to literature. In our experience we observed only large PA so to require an open surgery but this approach has allowed the rescue of graft functioning just in a single case. Endovascular procedures are linked to higher rate of graft salvage than surgery but they can be used just in selected cases., Conclusions: Our experience and literature review led us to believe that the rate of graft salvage in patients with large PA at anastomosis site could be improved only by a planned therapeutic program that includes surgical and endovascular approach, taking the advantages of both technique and overcoming their limits.

Intraoperative radioimmunodetection is a new staging technique for epithelial neoplasms. After intravenous injection, a radioimmunoconjugate compound (monoclonal antibody and isotope) attaches itself to the antigens expressed on the surface of neoplastic cells, causing them to emit gamma rays. Radioactivity is detected at the presurgical stage by immunoscintigraphy and intraoperatively with a gamma-detecting probe (GDP). In our experience, intraoperative tumor-to-normal-tissue (T/NT) GDP ratio counts > or =3:1 were considered positive radioimmunoguided surgery (RIGS) findings. We studied 52 colorectal cancer patients, 48 with primary lesions and 7 with relapses. Positive RIGS findings were obtained in 33 patients whose lymph node assessments were characterised by eight false positive identifications. In 10 patients, RIGS data yielded a more accurate staging of the disease. Unreliable RIGS findings were recorded in 15 patients: four injected with monoclonal antibody (MAb) B72.3 labeled with Iodine-125; five with MAb anti-carcinoembryonic antigen (CEA) labeled with 99mTechnetium (Tc); two with MAb B72.3 labeled with Indium-111; and three with MAb B72.3 labeled with Iodine-131 plus interferon-beta. In analysis, our experience did not permit definitive evaluation of the method's diagnostic and staging accuracy.
