A New Medium (HistoCold) for Surgical Specimens Preserving to Improve the Preanalytic Issues in Histopathological Samples Handling: Morphologic and Antigenic Analysis.

Introduction: The onset of precision medicine has led to the integration of traditional morphologic tissues evaluation with biochemical and molecular data for a more appropriate pathological diagnosis. The preanalytic phase and, particularly, timing of cold ischemia are crucial to guarantee high-quality biorepositories of formalin-fixed paraffin-embedded (FFPE) tissues for patients' needs and scientific research. However, delayed fixation using the gold-standard and carcinogenic fixative neutral-buffered formalin (NBF) can be a significant limitation to diagnosis and biopathological characterization. HistoCold (patented; Bio-Optica Milano S.p.A., Milano, Italy) is a nontoxic, stable, and refrigerated preservative solution for tissue handling. This study examined HistoCold's potential role in improving the preanalytic phase of the pathological diagnostic process. Materials and Methods: Breast, lung, or colorectal cancers (20, 25, and 10 cases, respectively) that were to be surgically resected were recruited between 2019 and 2021. Once specimens were surgically removed, three residual samples for each patient were first promptly immersed into HistoCold for 24, 48, and 72 hours and then FFPE. These were compared with routine specimens regarding morphologic features (hematoxylin and eosin) and tissue antigenicity (immunohistochemical stains). Results: Good concordance regarding both the morphologic characteristics of the neoplasms and their proteins expression between the routine and HistoCold handled tissues were found. The tissue handling with the solution never affected the histopathological diagnosis. Conclusions: The use of HistoCold for samples transporting is easy, allows for improving the management of cold ischemia time, and monitoring the fixation times in NBF, resulting in good quality tissue blocks for biobanking. Moreover, it could be a candidate to eliminate formalin from operating theaters. HistoCold looks very promising for the preanalytic phase of human tissues handling in the era of precision medicine, to provide the best service to patients, and to scientific research.

Prognostic value of high-sensitivity cardiac troponin I early after coronary artery bypass graft surgery.

BACKGROUND: The diagnosis of periprocedural myocardial infarction (PMI) after coronary artery bypass graft (CABG) is based on biochemical markers along with clinical and instrumental findings. However, there is not a clear cutoff value of high-sensitivity cardiac troponin (hs-cTn) to identify PMI. We hypothesized that isolated hs-cTn concentrations in the first 24 h following CABG could predict cardiac adverse events (in-hospital death and PMI) and/or left ventricular ejection fraction (LVEF) decrease. METHODS: We retrospectively enrolled all consecutive adult patients undergoing CABG, alone or in association with other cardiac surgery procedures, over 1 year. Hs-cTn I concentrations (Access, Beckman Coulter) were serially measured in the post-operative period and analyzed according to post-operative outcomes. RESULTS: 300 patients were enrolled; 71.3% underwent CABG alone, 33.7% for acute coronary syndrome. Most patients showed hs-cTn I values superior to the limit required by the latest guidelines for the diagnosis of PMI. Five patients (1.7%) died, 8% developed a PMI, 10.6% showed a LVEF decrease ≥ 10%. Hs-cTn I concentrations did not significantly differ with respect to death and/or PMI whereas they were associated with LVEF decrease ≥ 10% (p value < 0.005 at any time interval), in particular hs-cTn I values at 9-12 h post-operatively. A hs-cTn I cutoff of 5556 ng/L, a value 281 (for males) and 479 (for females) times higher than the URL, at 9-12 h post-operatively was identified, representing the best balance between sensitivity (55%) and specificity (79%) in predicting LVEF decrease ≥ 10%. CONCLUSIONS: Hs-cTn I at 9-12 h post-CABG may be useful to early identify patients at risk for LVEF decrease and to guide early investigation and management of possible post-operative complications.

Clinical profile and in-hospital outcome of patients supported by intra-aortic balloon pump in the clinical setting of cardiogenic shock.

Background: Despite controversial evidences, intra-aortic balloon pump (IABP) is still the most widely used temporary mechanical support device in cardiogenic shock (CS), as a bridge to recovery or to more invasive mechanical supports/heart transplantation. Methods: We analyzed retrospectively data of all patients receiving IABP for CS from 2009 to 2018 in a referral centre for advanced heart failure and heart transplantation; we included CS following acute coronary syndrome (ACS) and other CS etiologies different from ACS. We excluded patients in which IABP was implanted as a support following cardiac surgery, non-cardiac surgery in patients with severe chronic heart failure, or in elective high risk or complicated Cath Lab procedures.We focused on in-hospital outcomes (including death, recovery, heart transplantation, LVAD) and IABP complications. Results: 403 patients received IABP, 303 (75.2%) following ACS and 100 (24.8%) in non-ACS CS. Non-ACS patients were younger (59 ± 18.3 vs 73.1 ± 12.6 years, p < 0.001), had lower median left ventricular ejection fraction (LVEF) (25% [18-35] vs 38% [25-45], p < 0.001). In patients with non-ACS etiologies IABP was more frequently a bridge to heart transplantation [20% (n = 20) vs 0.3% (n = 1), P < 0.001] or LVAD [4% (n = 4) vs 0.6% (n = 2), P = 0.055], while ACS patients were more frequently discharged without transplantation/LVAD [65.7% (n = 199) vs 33% (n = 33), P < 0.001]. Non-ACS patients showed higher in-hospital mortality [46% (n = 46) vs 33.9% (n = 103), P = 0.042]. Post-transplant/LVAD outcome in non-ACS subgroup was favorable (21 out of 24 patients were discharged). Serious IABP-related adverse events occurred in 21 patients (5.2%). Ischemic/hemorrhagic complications, infections and thrombocytopenia were more frequent with longer IABP stay. Conclusions: Despite therapy including percutaneous circulatory support, mortality in CS is still high. In our experience, in the clinical setting of refractory CS an IABP support represents a relatively safe circulatory support, associated with a low rate of serious complications in complex clinical scenarios.

The Management of Acute Colonic Diverticulitis in the COVID-19 Era: A Scoping Review.

Background and Objective: During the COVID-19 pandemic, health systems worldwide made major changes to their organization, delaying diagnosis and treatment across a broad spectrum of pathologies. Concerning surgery, there was an evident reduction in all elective and emergency activities, particularly for benign pathologies such as acute diverticulitis, for which we have identified a reduction in emergency room presentation with mild forms and an increase with more severe forms. The aim of our review was to discover new data on emergency presentation for patients with acute diverticulitis during the Covid-19 pandemic and their current management, and to define a better methodology for surgical decision-making. Method: We conducted a scoping review on 25 trials, analyzing five points: reduced hospital access for patients with diverticulitis, the preferred treatment for non-complicated diverticulitis, the role of CT scanning in primary evaluation and percutaneous drainage as a treatment, and changes in surgical decision-making and preferred treatment strategies for complicated diverticulitis. Results: We found a decrease in emergency access for patients with diverticular disease, with an increased incidence of complicated diverticulitis. The preferred treatment was conservative for non-complicated forms and in patients with COVID-related pneumonia, percutaneous drainage for abscess, or with surgery delayed or reserved for diffuse peritonitis or sepsis. Conclusion: During the COVID-19 pandemic we observed an increased number of complicated forms of diverticulitis, while the total number decreased, possibly due to delay in hospital or ambulatory presentation because of the fear of contracting COVID-19. We observed a greater tendency to treat these more severe forms by conservative means or drainage. When surgery was necessary, there was a preference for an open approach or a delayed operation.

Accuracy and feasibility of SentiMag technique for localization of non-palpable breast lesions.

BACKGROUND: Non-palpable breast lesions are more frequent now than in the past due to the attention toward the mammary pathology and the screening diffusion; the marking of such lesions is very important for a successful surgery. The SentiMag System uses a magnetic marker that is inoculated transdermal in the breast through an 18-gauge needle. METHODS: Between April 1st and June 30th, 2018, 16 patients with non-palpable breast lesions were selected and subjected to surgery using the SentiMag System in our Unit. They were women with a mean age of 52 years (range 30-84 years). Seven of 16 (43.7%) had a borderline preoperative histological or cytological diagnosis (C3/B3), and nine (56.3%) a diagnosis of carcinoma (C5/B5). Six (37.5%) were marked on ultrasound guidance and 10 (62.5%) on a mammography stereotaxic guide. RESULTS: The time for the marker positioning ranged from 2 to 10 minutes. The radiological control of the surgical specimen always showed the presence of both the lesion and the marker, both centered within the specimen and intact. The pathology revealed seven benign lesions, one in-situ, and eight infiltrating carcinomas. CONCLUSIONS: The SentiMag represents a fast and safe preoperative marking system of non-palpable breast lesions, cutting the radio exposure for personnel and patients. The marker is not displaced over time and it is rapid to place and easy to locate intraoperatively, allowing a clear dissection plane around the lesion. Thus, this reduces the amount of gland removed, improving the aesthetic result mostly in small breasts.

kOBCS©: a novel software calculator program of the Objective Breast Cosmesis Scale (OBCS).

PURPOSE: The Objective Breast Cosmesis Scale (OBCS) is an objective method that documents the aesthetic changes in breast cancer patients. This work evaluates the kOBCS© software (http://www.kobcs.info) which simplifies the estimation of the OBCS values. METHODS: Five schematic drawings were photographed and imported into the kOBCS©. Thirty photos of breast cancer patients were imported into kOBCS©; 20 users (experts and non-experts) evaluated the photographs on two different settings. Subjective evaluation was performed using the Harvard breast cosmesis scale. RESULTS: There was a highly significant correlation between the OBCS values based on hand measurements and the values estimated by kOBCS© (r = 0.997, P < 0.001). Agreement among the users using the kOBCS© was strong with high statistical significance (ICC = 0.846, P < 0.001, 95% CI 0.774-0.910, Cronbach's alpha = 0.991). Results of the subjective analyses and mean OBCS values as estimated by kOBCS© correlated significantly (r = 0.961, P < 0.001). CONCLUSIONS: The kOBCS© is a reliable and reproducible easy-to-use software for reporting breast cosmesis following breast-conserving therapy.

Reduction of postoperative lymphorrhoea in patients undergoing radical lymphadenectomy for stage III melanoma: prospective study using collagen-fibrin patches.

BACKGROUND: Radical lymph nodes dissection (RLND) is the standard procedure for regional control of disease in patients with metastatic melanoma (stage III). Because of its aggressiveness, lymphorrhoea is a constant problem in postoperative. METHODS: In this prospective nonrandomized study with a retrospective analysis of data, patients undergoing surgical treatment of axillary or iliac-inguinal RLND received standard treatment plus a collagen-fibrin sealant patch (TachoSil) (N.=50) or standard treatment alone (N.=50). The first endpoint was the comparison between the treated population and the control group, in terms of persistence of drainage and average daily volume of lymphorrhoea. The second aim was to relate patients' BMI, volume of lymphorrhoea and time of drainage in the two groups. RESULTS: In the comparison between the two groups receiving or not the treatment with collagen-fibrin patch, we found an average difference both in the volume of daily lymphorrhoea (42.91±6.61 cc) and in the persistence of drainage (9.292±1.644 days) with P value <0.0001. Besides, the collagen-fibrin patch was actually effective in reducing lymphorrhoea and time of drainage, regardless of patients' BMI. CONCLUSIONS: The results of this study confirm and support the starting thesis: TachoSil is an effective tissue sealant able to reduce lymphorrhoea and drainage removal times following a radical lymphadenectomy, independently from the BMI.

Surgical treatment of gastrointestinal stromal tumors of the duodenum: a literature review.

BACKGROUND: Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumours in the digestive tract. The duodenal GIST (dGIST) is the rarest subtype, representing only 4-5% of all GIST, but up to 21% of the resected ones. The diagnostic and therapeutic management of dGIST may be difficult due to the rarity of this tumor, its anatomical location, and the clinical behavior that often mimic a variety of conditions; moreover, there is lack of consent for their treatment. This study has evaluated the scientific literature to provide consensus on the diagnosis of dGIST and to outline possible options for surgical treatment. METHODS: An extensive research has been carried out on the electronic databases MEDLINE, Scopus, EMBASE and Cochrane to identify all clinical trials that report an event or case series of dGIST. RESULTS: Eighty-six studies that met the inclusion criteria were identified with five hundred forty-nine patients with dGIST: twenty-seven patients were treated with pancreatoduodenectomy and ninety-six with only local resection (segmental/wedge resections); in four hundred twenty-six patients it is not possible identify the type of treatment performed (pancreatoduodenectomy or segmental/wedge resections). CONCLUSIONS: dGISTs are a very rare subset of GISTs. They may be asymptomatic or may involve symptoms of upper GI bleeding and abdominal pain at presentation. Because of the misleading clinical presentation the differential diagnosis may be difficult. Tumours smaller than 2 cm have a low biological aggressiveness and can be followed annually by endoscopic ultrasound. The biggest ones should undergo radical surgical resection (R0). In dGIST there is no uniformly adopted surgical strategy because of the low incidence, lack of experience, and the complex anatomy of the duodenum. Therefore, individually tailored surgical approach is recommended. R0 resection with 1-2 cm clear margin is required. Lymph node dissection is not recommended due to the low incidence of lymphatic metastases. Tumor rupture should be avoided.

Complications of Cardiac Transplantation.

PURPOSE OF REVIEW: Despite the improvement in medical therapy for heart failure and the advancements in mechanical circulatory support, heart transplantation (HT) still remains the best therapeutic option to improve survival and quality of life in patients with advanced heart failure. Nevertheless, HT recipients are exposed to the risk of several potential complications that may impair their outcomes. In this article, we aim to provide a practical and scholarly framework for clinicians approaching heart transplant medicine, as well as a concise update for the experienced readers on the most relevant post-HT complications. RECENT FINDINGS: While recognizing that most of the treatments herein discussed are based more on experience than on solid scientific evidence, significant step forward has been made in particular in the recognition and management of primary graft dysfunction, antibody-mediated rejection, and renal dysfunction. Complications after HT may vary according to the time from surgery and can be related to graft function and pathology or to diseases and dysfunctions occurring in other organs or systems, mainly as side effects of immunosuppressive drugs and progression of pre-existing conditions. Future research needs to focus on improving precision diagnostics of causes of graft dysfunction and on reaching an optimal and customized balance between efficacy and toxicities of immunosuppressive strategies.

Urgency surgical treatment for duodenal GISTs: analysis of aged patients and review of the literature.

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms (85%) of the gastrointestinal (GI) tract; duodenal GISTs constitute 3-5% of all GISTs and represent 10-30% of all malignant tumours of the duodenum. Rarely, patients present severe bowel obstruction, perforation or severe bleeding. The radical resection with complete removal of the tumour remains the main therapeutic approach. We performed a local resection in patients with suspected GIST admitted for emergency treatment for GI bleeding. CASES: We present three cases of patients admitted for GI bleeding. The cause could be a GIST bleeding. In all cases, local resection was performed without a pancreaticoduodenectomy. Histological examination on surgical preparations showed that in two cases it was a GIST and in one case, it was a leiomyoma. DISCUSSION: Surgery remains the treatment of choice in the case of a GIST primitive without evidence of metastases, even for patients who are hospitalized for a bleeding emergency. Wide resections are not needed; it is important to remove completely the disease. In the case of duodenal GIST, it is important to get negative margins near the head of the pancreas, and this could take a PD. According to our experience and to the literature review, we believe that if the duodenal papilla or the periampullary region is not interested, you must perform a local resection. This is also because non-malignant tumours may present as GISTs and in these cases it is not recommended to run a PD. CONCLUSION: The treatment of choice for duodenal GISTs is complete surgical resection with negative resection margins. When the papilla or the periampullary region is involved we choose to perform pancreaticoduodenectomy; otherwise it is better to perform a local resection. In fact, local resection has lower morbidity and mortality, with a comparable outcome.

Clinical Use of Doppler Echocardiography in Organic Mitral Regurgitation: From Diagnosis to Patients' Management.

Knowledge of mitral regurgitation (MR) is essential for any care provider, and not only for those directly involved in the management of cardiovascular diseases. This happens because MR is the most frequent valvular lesion in North America and the second most common form of valve disease requiring surgery in Europe. Furthermore, due to the ageing of the general population and the reduced mortality from acute cardiovascular events, the prevalence of MR is expected to increase further. Doppler echocardiography is essential both for the diagnosis and the clinical management of MR. In the present article, we sought to provide a practical step-by-step approach to help either performing a Doppler echocardiography or interpreting its findings in light of contemporary knowledge on organic (but not only) MR.

Distal pancreatectomy with splenic preservation: A short-term outcome analysis of the Warshaw technique.

INTRODUCTION: Spleen-preserving left pancreatectomy (SPDP) with splenic vessels preservation (SVP) or without (Warshaw technique, WT) has been described with robotic, laparoscopy and open surgery. Nevertheless, significant data on medium- and long-term follow-up are still not available, since data in literature are scarce and the level of evidence is low. METHODS: In this retrospective study, we describe and compare short and medium term results of spleen-preserving distal pancreatectomy in eight patients. RESULTS: In WT group the duration and the intraoperative bleeding was superior than SVP group. The incidence of perigastric collateral vessels and presence of submucosal varices evidenced at CT scan was 66% in WT group, while only one case occurred in SVP group. DISCUSSION: The limit of laparoscopic approach is the fact that it needs advanced laparoscopic skills, which might result in intraoperative bleeding and splenectomy. The most of literature considered salvage WT intraoperatively performed in case of classical SVP and not only elective WT. The consequence is that there is no difference in immediate postoperative results (operative time, intraoperative bleeding, hospital stay) that are in favour of SVP because WT is performed only in case of failure in preserving the splenic vessels. In fact when this intervention is performed electively, the procedure time is reduced as well as the intraoperative bleeding. CONCLUSIONS: WT is safe and feasible, even if there are not definitive evidences that demonstrate it is superior to classic SVP. RCTs are needed to determine advantages and disadvantages of WT compared to the classic SVP.

Road accident due to a pancreatic insulinoma: a case report.

Insulinoma is a rare pancreatic endocrine tumor, typically sporadic and solitary. Although the Whipple triad, consisting of hypoglycemia, neuroglycopenic symptoms, and symptoms relief with glucose administration, is often present, the diagnosis may be challenging when symptoms are less typical. We report a case of road accident due to an episode of loss of consciousness in a patient with pancreatic insulinoma. In the previous months, the patient had occasionally reported nonspecific symptoms. During hospitalization, endocrine examinations were compatible with an insulin-producing tumor. Abdominal computerized tomography and magnetic resonance imaging allowed us to identify and localize the tumor. The patient underwent a robotic distal pancreatectomy with partial omentectomy and splenectomy. Insulin-producing tumors may go undetected for a long period due to nonspecific clinical symptoms, and may cause episodes of loss of consciousness with potentially lethal consequences. Robot-assisted procedures can be performed with the same techniques of the traditional surgery, reducing surgical trauma, intraoperative blood loss, and hospital stays.

Role of damage control surgery in the treatment of Hinchey III and IV sigmoid diverticulitis: a tailored strategy.

Many of the treatment strategies for sigmoid diverticulitis are actually focusing on nonoperative and minimally invasive approaches. The aim of this systematic review was to evaluate the actual role of damage control surgery (DCS) in the treatment of generalized peritonitis caused by perforated sigmoid diverticulitis.A literature search was performed in PubMed and Google Scholar for articles published from 1960 to July 2013. Comparative and noncomparative studies that included patients who underwent DCS for complicated diverticulitis were considered.Acute Physiology and Chronic Health Evaluation score, duration of open abdomen, intensive care unit length of stay, reoperation, bowel resection performed at first operation, fecal diversion, method, and timing of closure of abdominal wall were the main outcomes of interest.According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses algorithm for the literature search and review, 10 studies were included in this systematic review. DCS was exclusively performed in diverticulitis patients with septic shock or requiring vasopressors intraoperatively. Two surgical different approaches were highlighted: limited resection of the diseased colonic segment with or without stoma or reconstruction in situ, and laparoscopic washing and drainage without colonic resection.Despite the heterogeneity of patient groups, clinical settings, and interventions included in this review, DCS appears to be a promising strategy for the treatment of Hinchey III and IV diverticulitis, complicated by septic shock. A tailored approach to each patient seems to be appropriate.

Robotic pancreaticoduodenectomy in a case of duodenal gastrointestinal stromal tumor.

BACKGROUND: Laparoscopic pancreaticoduodenectomy is rarely performed, and it has not been particularly successful due to its technical complexity. The objective of this study is to highlight how robotic surgery could improve a minimally invasive approach and to expose the usefulness of robotic surgery even in complex surgical procedures. CASE PRESENTATION: The surgical technique employed in our center to perform a pancreaticoduodenectomy, which was by means of the da Vinci™ robotic system in order to remove a duodenal gastrointestinal stromal tumor, is reported. CONCLUSIONS: Robotic technology has improved significantly over the traditional laparoscopic approach, representing an evolution of minimally invasive techniques, allowing procedures to be safely performed that are still considered to be scarcely feasible or reproducible.

A rare nosological entity: the perforated solitary cecal diverticulum. Research article.

AIM: To describe three cases of solitary cecal diverticulum, and trying to evaluate the better method of diagnosis and treatment with analysis of the literature. MATERIAL OF STUDY: Description of three cases of solitary cecal diverticulum's perforation admitted in the Department of General and Oncologic Surgery, Santa Maria della Misericordia Hospital, Perugia, during the period January 2011 - January 2012. RESULTS: In all patients the clinical presentation was very similar to that of acute appendicitis. Preoperative diagnosis was achieved in one case through abdominal CT scan, other two cases were identified at final pathology. At one year from the treatment all patient are still alive. DISCUSSION: Cecal diverticulum is a rare condition, often diagnosed either casually or because of inflammatory or perforative complications. The highest incidence is found in Western population. Because of the clinical presentation, very similar to the appendicitis, and the inflammatory reaction involving the colon and its surrounding tissues, the pre- and intra-operative diagnosis are very difficult. The diagnosis is almost always histological. The treatment may vary from simple expectant medical management, carried out with bowel rest, parenteral support and antibiotics as for left-sided diverticulitis, to surgical approach, performed through simple diverticulectomy or by classical right hemicolectomy. CONCLUSION: Pre-surgical and, also intra-operative, diagnosis of perforated solitary cecal diverticulum is clearly difficult. CT scan represents the gold standard for the differential diagnosis. Right hemicolectomy is an effective and safe approach, allowing accurate control, preventing complications and recurrences, and it represents the optimal management of the disease.

Case series of non-operative management vs. operative management of splenic injury after blunt trauma.

BACKGROUND: The spleen is the most easily injured organ in abdominal trauma. The conservative, operative approach has been challenged by several reports of successful non-operative management aided by the power of modern diagnostic imaging. The aim of our retrospective study was to compare non-operative management with surgery for cases of splenic injury. METHODS: We compared seven patients who were treated with non-operative management (NOM) between 2007 and 2011 to six patients with similar pre-operative characteristics who underwent operative management (OM). RESULTS: The average hospital stay was lower in the NOM group than in the OM group, although the difference was not statistically significant. The NOM group required significantly fewer transfusions, and no patients in the NOM group required admission to the intensive care unit. In contrast 83% of patients in the OM group were admitted to the intensive care unity. The failure rate of NOM was 14.3% in our experience. CONCLUSION: In our experience, NOM is the treatment of choice for grade I, II and III blunt splenic injuries. NOM is slightly less than surgery, but this is an unadjusted comparison and the 95% confidence interval is extremely wide - from 0.04 to 16.99. Splenectomy was the chosen technique in patients who met exclusion criteria for NOM, as well as for patients with grade IV and V injury.

The integrated role of ultrasonography in the diagnosis of soft tissue metastases from melanoma: preliminary report of a single-center experience and literature review.

Currently melanoma has the fastest growing incidence of all cancers in men and the second in women (after lung cancer) in Western countries. Since prognosis of skin melanoma is excellent in early stages but dramatically worsens in advanced stages, an early diagnosis is fundamental in granting patients a favorable outcome. Sentinel node (SN) biopsy represents the gold standard for accurately staging melanoma, but other tests are commonly endorsed both in the initial staging work-up and in the follow-up, such as ultrasonography, computed tomography (CT)-scan and positron emission tomography (PET)-CT. PET-CT, among others, has high sensitivity and specificity for the study of distant metastases, the assessment of soft tissues and lymph node involvement, and for the guidance of surgical biopsies. Ultrasonography (US) is a non-invasive procedure whose use has recently expanded in our service, both preoperatively, intraoperatively and postoperatively, thanks to its wide availability, low costs and easy and fast reproducibility; ultrasonography even surpassed the reliability of PET-CT or CT-scan in the seven cases presented herein. US is operator-dependent, and this is probably the major limitation of the procedure, together with lack of prospective studies validating its strength, but our preliminary study demonstrates that ultrasound can assume an important role in melanoma, both for staging and the follow-up of patients, especially with lymph nodal or subcutaneous involvement.

Optimizing therapeutic timing in patients undergoing mastectomy through use of the Tiloop® synthetic mesh: single-step surgery.

Patients undergoing mastectomy for breast cancer have to face a long and elaborated therapeutic path, very often burdened by reoperation to replace the temporary expander, used to enlarge the submuscular pouch, with a definitive implant. Postoperative planning represents a critical moment of care, as it requires the integration of multiple treatments (chemotherapy, radiotherapy, hormonotherapy) each with a specific deadline. We believe that in such a complex multidisciplinary approach, coordination among the different therapeutic phases should be the key to success. The aim of the Breast Unit is to manage rapidly the ad hoc paths set out for each patient in order to guarantee compliance with adequate therapeutic timing. With this purpose in mind we tested the advantage of immediate reconstruction with definitive implants, by using a polypropylene mesh which, prolonging the inferolateral profile of the pectoralis major muscle (PMM), allows for direct accommodation of the desired implant volume. This leads to a single-step surgical approach, guaranteeing at the same time reduced interference with adjuvant therapies and good aesthetic results. We applied this technique to 4 patients, one of which was bilateral and, in spite of the restricted number of cases, our results seem to be promising.

Oncologic reliability of nipple-sparing mastectomy for selected patients with breast cancer.

BACKGROUND: Nipple sparing mastectomy (NSM) is the current surgical alternative to conventional techniques, when mastectomy is required. This less invasive procedure safeguards the integrity of the nipple areola complex (NAC), whose removal is recognized as a factor that exacerbates the patient's feeling of mutilation, however ensuring oncological radicality for women with breast cancer. PATIENTS AND METHODS: From January 2003 to January 2011, 77 patients underwent Nipple Sparing Mastectomy (NSM). Patients were carefully selected according to specific criteria. When requested, postoperative radiotherapy on the residual glandular tissue was performed within 6 months of surgery. Patients were on close clinical and instrumental follow-up every 4 months for 2 years and every 6 months for the remaining 3 years. RESULTS: Of the 77 patients who underwent NSM, 10 suffering from bilateral cancer were subjected to bilateral procedure, for a total of 87 performed procedures. Furthermore, in the same group, 13 NSMs were carried out for preventive purposes. The average diameter of resected tumors was 13.5 mm, with a range of 2 to 25 mm. During the follow-up (range 23-115 months, mean 50.33 months) 2 locoregional recurrences in the NAC were observed, identified through instrumental check, and surgically treated by NAC removal after 33 and 37 months respectively. CONCLUSION: According to the litterature data and confirmed by our experience, we consider NSM as an oncologically safe technique that, in the respect of inclusion criteria may be performed in any patient with indication to mastectomy. A careful selection of patients by a multidisciplinary team according to strict criteria is the key in determining feasibility as well as oncological safety and should lead the general acceptance and widespread use of such surgical technique.
