RESUMO
BACKGROUND: Laparoscopic cholecystectomy is considered the gold standard for the treatment of gallbladder lithiasis; nevertheless, the incidence of bile duct injuries (BDI) is still high (0.3-0.8%) compared to open cholecystectomy (0.2%). In 1995, Strasberg introduced the "Critical View of Safety" (CVS) to reduce the risk of BDI. Despite its widespread use, the scientific evidence supporting this technique to prevent BDI is controversial. METHODS: Between March 2017 and March 2019, the data of patients submitted to laparoscopic cholecystectomy in 30 Italian surgical departments were collected on a national database. A survey was submitted to all members of Italian Digestive Pathology Society to obtain data on the preoperative workup, the surgical and postoperative management of patients and to judge, at the end of the procedure, if the isolation of the elements was performed according to the CVS. In the case of a declared critical view, iconographic documentation was obtained, finally reviewed by an external auditor. RESULTS: Data from 604 patients were analysed. The study population was divided into two groups according to the evidence (Group A; n = 11) or absence (Group B; N = 593) of BDI and perioperative bleeding. The non-use of CVS was found in 54.6% of procedures in the Group A, and 25.8% in the Group B, and evaluating the operator-related variables the execution of CVS was associated with a significantly lower incidence of BDI and intraoperative bleeding. CONCLUSIONS: The CVS confirmed to be the safest technique to recognize the elements of the Calot triangle and, if correctly performed, it significantly impacted on preventing intraoperative complications. Additional educational programs on the correct application of CVS in clinical practice would be desirable to avoid extreme conditions that may require additional procedures.

PURPOSE: To investigate the safety and outcomes of laparoscopic control of intraperitoneal mesh positioning in open umbilical hernia repair. METHODS: This study is a retrospective review of a series of adult patients with uncomplicated umbilical hernia who underwent elective open repair with a self-expanding patch with laparoscopic control from March 2011 to December 2018. The adequacy of mesh positioning was inspected with a 5-mm 30° scope in the left flank. The primary endpoint was recurrence. Secondary endpoints were rate of mesh repositioning, intraoperative complications and time, length of stay and postoperative pain. RESULTS: Thirty-five patients underwent open inlay repair of primary umbilical hernia with laparoscopic control. Six patients (17.1%) were obese. The mean operating time was 63.3 min. The mean defect size was 2.6 cm (0.6-5) and the mean mesh overlap was 3.2cm (2.2-4.5). There were no intraoperative complications. Laparoscopic control required mesh repositioning in 5 cases (14.3%). The median length of stay was 2 days. Perioperative complications were recorded in three cases (8.6%): one seroma and two serous wound discharge (Clavien-Dindo I). The recurrence rate was 2.9% (1 case) at a median follow-up of 60 months. BMI>30 was associated with a higher rate of intraoperative mesh repositioning (p=0.001). Non-reabsorbable mesh and COPD were associated with a higher incidence of postoperative complications (p=0.043). Postoperative pain scores were consistently at mild levels, with no statistically significant differences between patients who had their mesh repositioned and those who had not. CONCLUSIONS: Laparoscopic control of mesh positioning is a safe addition to open inlay umbilical hernia repair and enables the accurate verification of correct mesh deployment with low complication and recurrence rates.

Summary: Vocal cord palsy (VCP) is one of the most frequent complications following thyroidectomy. We evaluated the outcomes of intraoperative reconstruction of the recurrent laryngeal nerve (RLN). Of 917 patients who underwent thyroid surgery in a single high-volume general surgery ward between 2000 and 2015, 12 (1.3%) were diagnosed with RLN injury and were retrospectively categorized into 2 groups: group A (n = 5), with intraoperative evidence of iatrogenic transection or cancer invasion of the RLN, and group B (n = 7), with postoperative confirmation of VCP. In group A, immediate microsurgical primary repair of the RLN was performed. Postoperative assessment included subjective ratings (aspiration and voice quality improvement) and objective ratings (perceptual voice quality according to the grade, roughness, breathiness, asthenia and strain [GRBAS] scale, and direct laryngoscopy). In group A, roughness, breathiness and strain were significantly lower at 9 months than at 3 months (p < 0.05). Although larger, multicentre studies are needed, the results suggest potentially excellent postoperative phonatory function after immediate RLN reconstruction.

Mirizzi's syndrome (MS) is a rare complication of the inveterate biliary lithiasis. Diagnostic and therapeutic standardization is still missing, especially since laparoscopic cholecystectomy has become the gold standard approach for symptomatic cholelithiasis. Our study is a retrospective analysis based on a case-series. It considered 370 cholecystectomies performed from 2006 to 2011. We selected 11 patients affected by MS (2.97%). We divided them according to Csendes' classification. Endoscopic Retrograde Cholangio-Pancreatography (ERCP) was used for biliary drainage when the patient suffered jaundice and/or cholangitis and, preoperatively, to confirm the suspicion of MS obtained through Magnetic Resonance Cholangio-Pancreatography (MRCP). We found it useful to exploit nasobiliary drainage (NBD) for intra-operative check of the biliary tree. In all 5 patients of the type 1 group MS was discovered intraoperatively and treated with Laparoscopic Sub-total Cholecystectomy (LSC). One patient suffered from biliary leakage, solved with NBD positioning. The type 2 group was made up of 2 women and 1 man. All of them were preoperatively submitted to ERCP and NBD positioning. Two underwent LSC and one was converted to laparotomy. The type 3 was represented by a 63-year-old woman suffering from recurrent cholangitis. She was submitted to MRCP, ERCP and then underwent LSC. The 2 patients affected by type 4 underwent open biliary reconstruction. In conclusion, every attempt should be made to identify MS prior to LCS since it will allow NBD insertion by ERCP. Once LCS is initiated, if MS is identified intra-operatively, we can provide the most practical surgical options.

In the multimodal strategy context, to implement healthcare-associated infection prevention, bundles are one of the most commonly used methods to adapt guidelines in the local context and transfer best practices into routine clinical care. One of the most important measures to prevent surgical site infections is surgical antibiotic prophylaxis (SAP). This narrative review aims to present a bundle for the correct SAP administration and evaluate the evidence supporting it. Surgical site infection (SSI) prevention guidelines published by the WHO, CDC, NICE, and SHEA/IDSA/APIC/AHA, and the clinical practice guidelines for SAP by ASHP/IDSA/SIS/SHEA, were reviewed. Subsequently, comprehensive searches were also conducted using the PubMed®/MEDLINE and Google Scholar databases, in order to identify further supporting evidence-based documentation. The bundle includes five different measures that may affect proper SAP administration. The measures included may be easily implemented in all hospitals worldwide and are based on minimal drug pharmacokinetics and pharmacodynamics knowledge, which all surgeons should know. Antibiotics for SAP should be prescribed for surgical procedures at high risk for SSIs, such as clean-contaminated and contaminated surgical procedures or for clean surgical procedures where SSIs, even if unlikely, may have devastating consequences, such as in procedures with prosthetic implants. SAP should generally be administered within 60 min before the surgical incision for most antibiotics (including cefazolin). SAP redosing is indicated for surgical procedures exceeding two antibiotic half-lives or for procedures significantly associated with blood loss. In principle, SAP should be discontinued after the surgical procedure. Hospital-based antimicrobial stewardship programmes can optimise the treatment of infections and reduce adverse events associated with antibiotics. In the context of a collaborative and interdisciplinary approach, it is essential to encourage an institutional safety culture in which surgeons are persuaded, rather than compelled, to respect antibiotic prescribing practices. In that context, the proposed bundle contains a set of evidence-based interventions for SAP administration. It is easy to apply, promotes collaboration, and includes measures that can be adequately followed and evaluated in all hospitals worldwide.
RESUMO
Pancreatoduodenectomy is an exceptional procedure that requires an extensive dissection of the supramesocolic region extended to the first jejunal limb. Lymphadenectomy, required for cancer, increases the dissection surface. The extensive preparation of the area is traditionally conducted with bipolar ormonopolar instruments, while clips, ligatures, and sutures are used for haemostasis. LigaSure™ vessel sealing(LSVS; Valleylab, Boulder, CO) is a technology that obtains vessel closure by using the body's own collagen and elastin to create a permanent fusion zone. This is obtained by a combination of forceps pressure and radio frequency. This effect has been improved by the introduction of the Force Triad™ (Valleylab, Boulder,CO) energy platform, controlled by TissueFect™ (Valleylab, Boulder, CO) sensing technology. With this device, the surgeon is able to fuse vessels up to 7 mm, lymphatics, tissue bundles, and pulmonary vasculature in a fast-seal cycle of almost 4 seconds. In our daily practice of open surgery we observe a rapid improvement of abdominal drainage output with a drastic reduction of protein loss. Its practical significance is, in our opinion, that we obtain a rapid recovery of normal serum protein levels with a low number of blood/plasmasac transfusions and a real improvement of anastomosis healing. Moreover, the efficacy and the speed of work of the device allow us to reduce the operating time significantly but safely. We performed a retrospective analysis of the data of 20 pancreatic resections conducted both with traditional dissection and with the Liga-Sure Impact device with Force Triad platform in order to verify whether observed data were real. Our clinical results show that the use of the LigaSure Impact device with Force Triad energy platform is really useful in open surgery to save operating time, number of postoperative days, and hemoderivate administration.

Aim of this study is to compare early post-operative outcomes and patient's satisfaction after skin-sparing and/or nipple-sparing mastectomy (SSM/SNSM) followed either by breast reconstruction with one-stage prepectoral implantation or two-stage technique for breast cancer (BC) or BRCA1/2 mutation.From January 2018 to December 2021, 96 patients (mean age of 51.12 ± 10.9) underwent SSM/SNSM and were divided into two groups: in group A (65 patients, 67.7%), mastectomy was followed by one-stage reconstruction; in group B (31 patients, 32.3%) by two-stage. Operative time was significantly longer in A vs. B (307.6 ± 95.7 vs. 254.4 ± 90.91; P < 0.05). Previous breast surgery was more common in B vs. A (29.0% vs. 7.7%; P < 0.05), while bilateral surgery was performed more frequently in A vs. B (40% vs. 6.5%; P = 0.001). All SSM/SNSM for BRCA1/2 mutation were followed by immediate prepectoral implantation. No significant differences were found between groups in terms of post-operative complications. At pathology, DCIS and invasive ST forms, such as multicentric/multifocal forms, were detected more frequently in B, while NST type in A (all P < 0.05). A multivariate analysis showed improved post-operative satisfaction at BREAST-Q survey in Group A (P = 0.001). Encouraging oncologic outcomes after SSM/SNSM for BC enabled the improvement of breast reconstructive techniques. One-stage reconstruction is characterized by better aesthetic outcomes and by greater patient's satisfaction. When SSM/SNSM is technically difficult to perform, as in multicentric/multifocal forms or previous breast surgery, mastectomy followed by two-stage reconstruction should be considered to achieve a radical surgery.

BACKGROUND: Parathyroid cancer (PC) is a rare sporadic or hereditary malignancy whose histologic features were redefined with the 2022 WHO classification. A total of 24 Italian institutions designed this multicenter study to specify PC incidence, describe its clinical, functional, and imaging characteristics and improve its differentiation from the atypical parathyroid tumour (APT). METHODS: All relevant information was collected about PC and APT patients treated between 2009 and 2021. RESULTS: Among 8361 parathyroidectomies, 351 patients (mean age 59.0 ± 14.5; F = 210, 59.8%) were divided into the APT (n = 226, 2.8%) and PC group (n = 125, 1.5%). PC showed significantly higher rates (p < 0.05) of bone involvement, abdominal, and neurological symptoms than APT (48.8% vs. 35.0%, 17.6% vs. 7.1%, 13.6% vs. 5.3%, respectively). Ultrasound (US) diameter >3 cm (30.9% vs. 19.3%, p = 0.049) was significantly more common in the PC. A significantly higher frequency of local recurrences was observed in the PC (8.0% vs. 2.7%, p = 0.022). Mortality due to consequences of cancer or uncontrolled hyperparathyroidism was 3.3%. CONCLUSIONS: Symptomatic hyperparathyroidism, high PTH and albumin-corrected serum calcium values, and a US diameter >3 cm may be considered features differentiating PC from APT. 2022 WHO criteria did not impact the diagnosis.
RESUMO
BACKGROUND: Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS: The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION: OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention. TRIAL REGISTRATION: National Institutes of Health ( https://clinicaltrials.gov/ct2/show/NCT03163095 ).

Introduction: The COVID-19 pandemic has led to the disruption of surgical training. Lack of communication, guidelines for managing clinical activity as well as concerns for safety in the workplace appeared to be relevant issues. This study aims to investigate how surgical training has been reorganized in Italy, almost 2 years after the outbreak of COVID-19 pandemic. Materials and methods: A 16-item-electronic anonymous questionnaire was designed through SurveyMonkey© web application. This survey was composed of different sections concerning demographic characteristics and impacts of the second COVID-19 pandemic wave on surgical and research/didactic activities. Changes applied in the training programme and activities carried out were also investigated. The survey was carried out in the period between June and October 2021. Results: Four hundred and thirty responses were collected, and 399 were considered eligible to be included in the study analysis. Three hundred and thirty-five respondents continued working in Surgical Units, with a significant reduction (less than one surgical session per week) of surgical sessions in 49.6% of them. With concern to didactic and research activities, 140 residents maintained their usual activity, while 116 reported a reduction. A sub-group analysis on resident moved to COVID-19 departments showed a reduction of research activities in 35% of them. During the period considered in this survey, the surgical training program was not substantially modified for most of participants (74.6%). Conclusion: Our survey demonstrated that surgical residency programs haven't improved 2 years after the beginning of the pandemic. Further improvements are needed to guarantee completeness of surgical training, even in emergency conditions.
RESUMO
In patients with advanced sepsis from abdominal disease, the open abdomen (OA) technique as part of a damage control surgery (DCS) approach enables relook surgery to control infection, defer intestinal anastomosis, and prevent intra-abdominal hypertension. Limited evidence is available on key outcomes, such as mortality and rate of definitive fascial closure (DFC), which are needed for surgeons to select patients and adequate therapeutic strategies. Abdominal closure with negative pressure wound therapy (NPWT) has shown rates of DFC around 90%. We conducted a retrospective study to evaluate in-hospital survival and factors associated with mortality in acute, non-trauma patients treated using the OA technique and NPWT for sepsis from abdominal disease. Fifty consecutive patients treated using the OA technique and NPWT between February 2015 and July 2022 were included. Overall mortality was 32%. Among surviving patients, 97.7% of cases reached DFC, and the overall complication rate was 58.8%, with one case of entero-atmospheric fistula. At univariable analysis, age (p = 0.009), ASA IV status (<0.001), Mannheim Peritonitis Index > 30 (p = 0.001) and APACHE II score (p < 0.001) were associated with increased mortality. At multivariable analysis, higher APACHE II was a predictor of in-hospital mortality (OR 2.136, 95% CI 1.08−4.22; p = 0.029). Although very resource-intensive, DCS and the OA technique are valuable tools to manage patients with advanced abdominal sepsis, allowing reduced mortality and high DFC rates.
RESUMO
Thyroid and parathyroid surgery are considered clean procedures, with an incidence of surgical site infection (SSI) after thyroidectomy ranging from 0.09% to 2.9%. International guidelines do not recommend routine antibiotic prophylaxis (AP), while AP seems to be employed commonly in clinical practice. The purpose of this systematic review is analyzing whether the postoperative SSI rate in thyroid and parathyroid surgery is altered by the practice of AP. We searched Pubmed, Scopus, the Cochrane Library, and Web of Science (WOS) for studies comparing AP to no preoperative antibiotics up to October 2021. Data on the SSI rate was evaluated and summarized as relative risks (RR) with 95% confidence intervals (95% CI). Risk of bias of studies were assessed with standard methods. Nine studies (4 RCTs and 5 nRCTs), including 8710 participants, were eligible for quantitative analysis. A meta-analysis showed that the SSI rate was not significantly different between AP and no preoperative antibiotics (SSI rate: 0.6% in AP vs. 2.4% in control group; RR 0.69, 0.43-1.10 95% CI, p = 0.13, I2 = 0%). A sensitivity analysis and subgroup analysis on RCTs were consistent with the main findings. Evidence of low quality supports that AP in thyroid and parathyroid surgery produce similar SSI rates as to the absence of perioperative antibiotics.
RESUMO
Splenic flexure mobilization (SFM) is one of the most difficult steps in laparoscopic colorectal surgery and its role is harshly debated. Some surgeons considered it routinely necessary to obtain a safe anastomosis and to respect oncologic criteria; for others SFM is frequently unnecessary, not ensuring the aspects mentioned above and increasing the risk of morbidity (splenic, bowel and vessels injury, lengthened procedure). We performed a systematic review and a comprehensive meta-analysis, without any language restriction, about the peri-operative and post-operative outcomes (anastomotic leakage, intra-operative complication, conversion rate, operative time, post-operative bleeding, intra-abdominal collection, prolonged ileus, wound infection, anastomotic stricture, overall complications, hospital stay, re-operation, post-operative mortality, R0 margin resection, local recurrence) in patients undergoing elective anterior rectal resection (ARR) with or without SFM, both in laparotomic (LT) and laparoscopic (LS) approach. Fourteen studies were meta-analyzed with a total amount of 42,221 patients. The comprehensive meta-analysis shows that the mobilization or the preservation (SFP) of the splenic flexure does not statistically influence the incidence of colorectal anastomotic leakage, conversion rate, post-operative bleeding, intra-abdominal collection, prolonged ileus, wound infection, anastomotic stricture, overall complications, hospital stay, re-operation, R0 margin resection, and local recurrence results. The operative time is significantly longer in every group of patients undergoing SFM. The incidence of intra-operative complication is statistically increased in overall patients and also in the LS subgroup of patients undergoing SFM, in which also higher incidence of wound infection and re-operation is shown. The meta-analysis shows that SFM may be considered not necessary to ensure better peri-operative and post-operative outcomes in both LT and LS ARR.

BACKGROUND: Lung cancer represents the second leading cause of death in US and the high mortality rate could be related to the diagnosis, usually, performed in an advanced metastatic stage. Gastrointestinal metastases from non-small cell lung cancer, are extremely rare and only few cases complicated by digestive haemorrhage and/or perforation have been reported in literature. MATERIAL AND METHODS: We report two cases of gastrointestinal metastases and their rare clinical onset with haemorrhage and perforation of the digestive tract. Both patients were admitted in an emergency setting. The first case was a 59-year-old man complained of abdominal pain and massive gastrointestinal haemorrhage. An upper gastrointestinal endoscopy revealed an ulcerated gastric mass and an emergency CT-scans showed a right lung mass with biopsy conclusive for a large cell lung cancer. The second case was a 62-year-old man with abdominal pain and shock due to gastrointestinal bleeding. He was submitted to an emergency CT-scan showing two lung nodules (1.0 and 3.5 cm of diameter) as well as widespread metastases, intraperitoneal free air and fluids. RESULTS: Both patients were surgical managed in emergency and pathology revealed the metastatic origin from an unknown large-cell lung cancer and a rare lung adenocarcinoma in the second one. CONCLUSIONS: Despite the rare clinical condition, in patients with a diagnosis of lung cancer managed in emergency for gastrointestinal complication, gastrointestinal metastases should be taken into account, and referred to the primary disease in order to tailor the best approach. KEY WORDS: Gastrointestinal metastases, Lung cancer, Tailored surgery.

INTRODUCTION: Emergency situations, as the COVID-19 pandemic that is striking the world nowadays, stress the national health systems which are forced to rapidly reorganize their sources. Therefore, many elective diagnostic and surgical procedures are being suspended or significantly delayed. Moreover, patients might find it difficult to refer to physicians and delay the diagnostic and even the therapeutic procedures because of emotional or logistic problems. The effect of diagnostic and therapeutic delay on survival in patients affected by gastrointestinal malignancies is still unclear. EVIDENCE ACQUISITION: We carried out a review of the available literature, in order to determine whether the delay in performing diagnosis and curative-intent surgical procedures affects the oncological outcomes in patients with esophageal, gastric, colorectal cancers, and colorectal liver metastasis. EVIDENCE SYNTHESIS: The findings indicate that for esophageal, gastric and colon cancers delaying surgery up to 2 months after the end of the staging process does not worsen the oncological outcomes. Esophageal cancer should undergo surgery within 7-8 weeks after the end of neoadjuvant chemoradiation. Rectal cancer should undergo surgery within 31 days after the diagnostic process and within 12 weeks after neoadjuvant therapy. Adjuvant therapy should start within 4 weeks after surgery, especially in gastric cancer; a delay up to 42 days may be allowed for esophageal cancer undergoing adjuvant radiotherapy. CONCLUSIONS: Gastrointestinal malignancies can be safely managed considering that reasonable delays of planned treatments appear a generally safe approach, not having a significant impact on long-term oncological outcome.

We sought to analyse the effect of the introduction of intraoperative nerve monitoring (IONM) in our routine surgical practice and to provide a circumstantial analysis of direct costs of IONM in total thyroidectomy and of indirect costs associated with vocal fold palsy, as centred in the health care system of Italy. We retrospectively compared outcomes of 232 total thyroidectomies performed between November 2017 and October 2019, respectively, before (109 TT-Group A) and after (123 TT-Group B) adopting IONM technology in November 2018. We analysed the costs of IONM per procedure and rate and costs of vocal fold palsy events (temporary and permanent). Overall, there were 61 thyroid cancers (32 in Group B) and 171 multinodular goitres (91 in Group B). We recorded 5 cases of vocal fold palsy (4.6%-4 transient, 1 permanent) in Group A and none in Group B (p = 0.016). IONM consumables cost 219 eur per case. Healthcare and social cost of Vocal fold palsy ranged between 3200 eur (function recovery < 1 month postoperatively) and over 32,000 eur (permanent event). When only direct costs are considered, IONM can hardly be cost effective. In this study, cost of IONM implementation was offset by the absence of complications attributable to recurrent laryngeal nerve dysfunction.

Thyroid cancer is the most common endocrine malignancy, with a typically favorable prognosis following standard treatments, such as surgical resection and radioiodine therapy. A subset of thyroid cancers progress to refractory/metastatic disease. Understanding how the tumor microenvironment is transformed into an angiogenic microenvironment has a role of primary importance in the aggressive behavior of these neoplasms. During tumor growth and progression, angiogenesis represents a deregulated biological process, and the angiogenic switch, characterized by the formation of new vessels, induces tumor cell proliferation, local invasion, and hematogenous metastases. This evidence has propelled the scientific community's effort to study a number of molecular pathways (proliferation, cell cycle control, and angiogenic processes), identifying mediators that may represent viable targets for new anticancer treatments. Herein, we sought to review angiogenesis in thyroid cancer and the potential role of proangiogenic cytokines for risk stratification of patients. We also present the current status of treatment of advanced differentiated, medullary, and poorly differentiated thyroid cancers with multiple tyrosine kinase inhibitors, based on the rationale of angiogenesis as a potential therapeutic target.
RESUMO
(1) Background: Lymph node metastases from papillary thyroid cancer (PTC) are frequent. Selective neck dissection (SND) is indicated in PTC with clinical or imaging evidence of lateral neck nodal disease. Both preoperative ultrasound (PreUS) and intraoperative palpation or visualization may underestimate actual lateral neck nodal involvement, particularly for lymph-nodes located behind the sternocleidomastoid muscle, where dissection may also potentially increase the risk of postoperative complications. The significance of diagnostic IOUS in metastatic PTC is under-investigated. (2) Methods: We designed a prospective diagnostic study to assess the diagnostic accuracy of IOUS compared to PreUS in detecting metastatic lateral neck lymph nodes from PTC during SND. (3) Results: There were 33 patients with preoperative evidence of lateral neck nodal involvement from PTC based on PreUS and fine-needle cytology. In these patients, IOUS guided the excision of additional nodal compartments that were not predicted by PreUS in nine (27.2%) cases, of which eight (24.2%) proved to harbor positive nodes at pathology. The detection of levels IIb and V increased, respectively, from 9% (PreUS) to 21% (IOUS) (p < 0.0001) and from 15% to 24% (p = 0.006). (4) Conclusions: In the context of this study, IOUS showed higher sensitivity and specificity than PreUS scans in detecting metastatic lateral cervical nodes. This study showed that IOUS may enable precise SND to achieve oncological radicality, limiting postoperative morbidity.
RESUMO
BACKGROUND: Circulating angiogenic factors have been associated with clinical outcomes of papillary thyroid carcinoma, although they may also be released in the context of benign multinodular goiter. We sought to investigate the effect of thyroidectomy on the activity and importance of multiple circulating angiogenic factors in papillary thyroid carcinoma and benign multinodular goiter. METHODS: Between May 2015 and December 2016, patients scheduled for total thyroidectomy for papillary thyroid carcinoma or benign multinodular goiter were offered to enroll in this study. Serum levels of angiopoietin-2, fibroblast growth factor-2, hepatocyte growth factor, platelet-derived growth factor-BB, placenta growth factor, heparin-binding epidermal growth factor, and vascular endothelial growth factor-A and -C were collected preoperatively and 2 weeks postsurgery. These levels were measured by enzyme-linked immunosorbent assay and compared with those of 35 healthy control subjects. RESULTS: Sixty patients with a median age of 52 years, 37 of whom were females, were included: 36 had papillary thyroid carcinoma, and 24 had benign multinodular goiter. In both benign multinodular goiter and papillary thyroid carcinoma, preoperative, circulating angiogenic factors levels were increased with respect to controls (P < .0001), and a decrease after total thyroidectomy was observed in the levels of angiopoietin-2 (P < .0001), fibroblast growth factor-2 (P < .0001), hepatocyte growth factor (P < .001), and heparin-binding epidermal growth factor (P < .01 each). Only patients with papillary thyroid carcinomas, however, showed decrease in the postoperative levels of platelet-derived growth factor-BB and vascular endothelial growth factor-A (P = .001 each). CONCLUSION: Results from this study raise the potential for vascular endothelial growth factor-A and platelet-derived growth factor-BB to be used as biomarkers of the effectiveness of treatment of papillary thyroid carcinoma. These results warrant further investigation and may have potential prognostic implications.

BACKGROUND: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA. METHODS: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations. RESULTS: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.
