RESUMO
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.

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.

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.

Lymphomas usually involve lymph nodes and other lymphoid tissues, but sometimes occur in non-lymphoid organs, called extra-nodal sites. Primary diffuse extra-lymph node large B-cell lymphoma (DLBCL) of the thyroid and parotid gland have been observed rarely. According to the most accredited guidelines, primary extra-nodal DLBCL of the parotid and thyroid glands should be treated with three cycles of R-CHOP followed by radiotherapy of the involved site (ISRT). Surgery alone is not enough to treat DLBCL. We describe two unusual cases of primary extra-nodal DLBCL in elderly patients treated exclusively with surgical resection, given the inability to apply chemotherapy. Both patients achieved clinical recovery, which was maintained after a follow-up of more than 18 months, despite not having performed the indicated chemotherapy protocol. The two cases presented here, and a few others reported in the literature, should be considered exceptions to the rule, and do not allow the conclusion that surgery alone might be sufficient for complete remission.
RESUMO
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.

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.

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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.

Gastric carcinoma is the second most common cause of digestive tumour-related death in Europe, North America and Asia. Today, the gold standard of treatment is still surgery, but outcomes to date are unsatisfactory. The Japanese Society for Research in Gastric Cancer (JSRGC) recommends the routine execution of splenectomy during gastrectomy. This recommendation is contested by western Authors because of increased morbidity and mortality without any real advantage in terms of survival. Patients treated for gastric cancer in our department between 1993 and 2002 were selected for this study. The 132 patients recruited were divided into two groups: a) those treated for gastric cancer without splenectomy; and b) those in whom splenectomy was performed in conjunction with gastrectomy. We analysed: the extent of lymph node dissection, the execution of the splenectomy, and the prognostic importance of factors relating to the patient, tumour and surgeon. Splenectomy was not associated with any increase in morbidity. Complications, especially of the septic type, and perioperative mortality were similar in both groups, and the same was true of survival at both 3 and 5 years. In our opinion, splenectomy should not be routinely combined with surgery for gastric cancer but could be considered for T3-T4 neoplasms or those localized in the upper two thirds of the stomach.

RESUMO
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.

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.

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.
