Robotic Versus Laparoscopic Minimally Invasive Surgery for Rectal Cancer: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Objective:The aim of this study was to evaluate the safety and efficacy of elective rectal resection for rectal cancer in adults by robotic surgery compared with conventional laparoscopic surgery. Summary of Background Data:Technological advantages of robotic surgery favor precise dissection in narrow spaces. However, the evidence base driving recommendations for the use of robotic surgery in rectal cancer primarily hinges on observational data. Methods:We searched MEDLINE, Embase, and CENTRAL for randomized controlled trials (until August 2016) comparing robotic surgery versus conventional laparoscopic surgery. Data on the following endpoints were evaluated: circumferential margin status, mesorectal grade, number of lymph nodes harvested, rate of conversion to open surgery, postoperative complications, and operative time. Data were summarized as relative risks (RR) or weighted mean differences (WMDs) with 95% confidence intervals (95% CIs). Risk of bias of studies was assessed with standard methods. Results:Five trials were eligible, including 334 robotic and 337 laparoscopic surgery cases. Meta-analysis showed that RS was associated with lower conversion rate (7.3%; 4 studies, 544 participants, RR 0.58; 95% CI 0.35–0.97, P = 0.04, I2 = 0%) and longer operating time (MD 38.43 minutes, 95% CI 31.84–45.01: P < 0.00001) compared with laparoscopic surgery. Perioperative mortality, rate of circumferential margin involvement (2 studies, 489 participants, RR 0.82, 95% CI 0.39–1.73), and lymph nodes collected (mean 17.4 Lymph Nodes; 5 trials, 674 patients, MD −0.35, 95% CI −1.83 to 1.12) were similar. The quality of the evidence was moderate for most outcomes. Conclusion:Evidence of moderate quality supports that robotic surgery for rectal cancer produces similar perioperative outcomes of oncologic procedure adequacy to conventional laparoscopic surgery. Robotic surgery portraits lower rate of conversion to open surgery, while operating time is significantly longer than by laparoscopic approach.

A Gelatin–Thrombin Matrix Topical Hemostatic Agent (Floseal) in Combination With Harmonic Scalpel Is Effective in Patients Undergoing Total Thyroidectomy A Prospective, Multicenter, Single-Blind, Randomized Controlled Trial

Background. Hemostasis during thyroidectomy is essential; however, the safest, most efficient, and most cost-effective way to achieve this is unclear. This randomized, multicenter, single-blind, prospective study evaluated the efficacy and safety of using different hemostatic approaches in patients undergoing total thyroidectomy. Methods. Patients aged ≥18 to 70 years were randomized to Floseal + a harmonic scalpel (HS), Floseal alone, HS alone, or standard total thyroidectomy. Primary endpoint was 24-hour drain output. Secondary endpoints included surgery duration and complications. Results. Two hundred and six patients were randomized to Floseal + HS (n = 52), Floseal alone (n = 54), HS alone (n = 50), and standard total thyroidectomy (n = 50). The 24-hour drain output was lower in the Floseal + HS group compared with standard thyroidectomy. Floseal + HS also had a shorter surgery time (P < .0001) versus the other 3 treatments. Conclusion. Floseal + HS can be effective at reducing postsurgical drain output and provides a complementary hemostatic approach in patients undergoing total thyroidectomy.

Bilateral benign multinodular goiter: What is the adequate surgical therapy? A review of literature

BACKGROUND Benign multinodular goiter (BMNG) is the most common endocrine disease requiring surgery. During the last few years a more aggressive approach has become the trend for bilateral BMNG treatment. METHOD Randomized clinical trials of any size that compared bilateral subtotal resection, Dunhill procedure and total thyroidectomy for benign multinodular goiter, published between January 2000 and the end of March 2015, were reviewed. DISCUSSION Total thyroidectomy can be considered the most reliable approach in preventing recurrence. The Dunhill procedure is related to a higher rate of recurrence, but rarely recurrences after Dunhill procedure lead to reoperation. Total thyroidectomy avoid completion thyroidectomy for incidental carcinoma and its related risks. Recurrent laryngeal nerve (RLN) palsy becomes less common as surgical experience increases. Transient and permanent hypoparathyroidism is strictly related to the extent of neck dissection. In the risk-cost analysis we must consider the type of patient candidated to surgery and the impact of the surgical protocol we apply. When thyroid surgery is taken in consideration, specific complication rates of different procedures in each hospital must be analyzed accordingly to patient-specific risk factors and local expertise. CONCLUSION The Dunhill procedure seems to be a good compromise between radicality and prevention of complications, avoiding reoperation for recurrence or completion thyroidectomy for incidental thyroid carcinoma. More follow-up studies and prospective studies are necessary to better evaluate, definitively, whether to prefer total thyroidectomy or Dunhill procedure in case of benign goiter surgery.

Clusterin transcript variants expression in thyroid tumor: a potential marker of malignancy?

BackgroundClusterin (CLU) is a ubiquitous multifunctional factor involved in neoplastic transformation. The CLU transcript variants and protein forms play a crucial role in balancing cells proliferation and death.MethodsWe investigated the regulation of CLU transcript variants expression in an in vivo model system consisting of both neoplastic tissues and fine needle aspiration biopsy (FNAB) samples isolated from patients undergoing thyroidectomy.ResultsThe immunohistochemical analyses showed an overall CLU up-regulation in papillary carcinoma. A specific CLU2 transcript variant increase was registered using qPCR in papillary carcinomas while CLU1 decreased. In addition, the analysis of CLU transcripts expression level showed an increase of the CLU2 transcript in the TIR 3 patients with histologically confirmed thyroid cancer.ConclusionsOur results suggest the existence of a specific alteration of CLU2:CLU1 ratio towards CLU2, thus providing the first circumstantial evidence for the potential use of CLU transcript variants as effective biomarkers for a more accurate assessment of the so called “indeterminate” thyroid nodules.

Effectiveness of an advanced hemostatic pad combined with harmonic scalpel in thyroid surgery. A prospective study

INTRODUCTION Hemostasis during thyroidectomy is essential; however the most efficient and cost-effective way to achieve this is unclear. The aim of this study was to evaluate the outcome of total thyroidectomy (TT) performed with the combination of harmonic scalpel (HS) and an advanced hemostatic pad (Hemopatch). METHODS Patient undergone TT were divided into two groups: HS + hemopatch and HS + traditional hemostasis groups. The primary endpoint was 24-h drain output and blood-loss requiring reintervention. Secondary endpoints included surgery duration, postsurgical complications and hypocalcemia rates. RESULTS Between September 2014 and March 2015, 60 patients were enrolled (30 to Hs + Hemopatch, 30 to Hs and standard hemostasis); 71.4% female; mean age 48.5 years. The 24-h drain output was lower in the HS + hemopatch group compared with standard TT. HS and hemopatch also had a shorter mean surgery time (p < 0.0001) vs standard TT. CONCLUSION combination of hemopatch plus HS is effective and safe for TT with a complementary hemostatic approach.

Clinical aggressiveness of incidental and non-incidental thyroid cancer.

Background: With the increasing use of thyroid ultrasound, the recognition of thyroid nodules in a large proportion of apparently healthy subjects has become common. Because also the papillary thyroid microcarcinomas (PTMC) are being increasingly discovered, it is important to ascertain whether PTMC may exhibit heterogenous clinical features, associated with different aggressiveness. Aim: We retrospectively examined 122 subjects [98 female (80.3%), and 24 male (19.7%)] with thyroid cancer to find potential clinical and pathological findings that could be predictive of clinically aggressive behavior. Results: Twenty of the 31 patients with true incidental cancer (64.5%) in comparison to 20 of the 91 patients with non-incidental cancer (21.9%) had a diameter <10 mm, and this difference was statistically significant (p<0.0001). There was a statistically significant association between size and invasiveness because 19.3% of invasive cancers were <10 mm whereas 44.6% of non-invasive cancers were <10 mm (p=0.005). The relationship between incidental discovery and invasiveness was also evaluated, but the proportion of incidental invasive cancer (19.3%) was not significantly different from that of incidental non-invasive cancer (30.8%). In the multivariate analysis, only size <10 mm (odds ratio=0.35, p=0.013) and papillary vs other histotypes (odds ratio=0.35, p=0.04) were statistically significant protective factors against invasiveness. Conclusions: a) Incidentally discovered thyroid cancers are more frequently microcarcinomas; b) there appears to be no difference in terms of invasive behavior between incidental and non-incidental thyroid cancer; c) smaller tumor size emerges as a protective factor.

Extralymphatic Disease Is an Independent Prognostic Factor in Hodgkin Lymphoma

&NA; A retrospective study was performed of 341 cases of extralymphatic Hodgkin lymphoma (HL) to identify its characteristics and outcomes. Sites were lung in 29 patients (44%), bone in 22 (33%), and liver in 5 (18%). Extralymphatic HL is a rare occurrence (16%) associated with poor clinical outcome. Purpose: To identify the characteristics and outcomes of patients with extralymphatic Hodgkin lymphoma. Patients and Methods: We performed a retrospective single‐institution study of 341 cases comprising 207 male (61%) and 134 female (39%) subjects with a median follow‐up of 44 months. Results: Fifty‐five patients (16%) had extralymphatic disease. The sites were lung in 29 patients (44%), bone in 22 (33%), liver in 12 (18%), and kidney in 3 (5%). In 46 patients (86%) only one organ was involved, while in 7 patients (13%) extralymphatic disease was present in 2 sites and in 2 patients (3%) in 3 sites. The extralymphatic disease group had a poorer prognosis than the lymphatic disease group. Complete remission rates in the extralymphatic and lymphatic patient subsets were 65% and 82% (P = .043), respectively. Conclusion: Extralymphatic disease in patients with Hodgkin lymphoma is a rare occurrence (16%) associated with poor clinical outcome.

Handover checklist: testing a standardization process in an Italian hospital

Objectives This study aimed to standardize and rationalize the handover, a critical and essential moment in common health care practices, through the realization of an efficient and standardized checklist, which could be used daily to ensure complete, thorough and effective handover. The principal purpose of the implementation of the handover is to reduce errors due to superficial and insufficient communication. Methods The “operative group” defined the phases to the realization of the delineated aims: at first, the direct observation and the consequent realization of a handover checklist model and then, the experimental phases (trials). The handover checklist model was used for a month and it was daily and duly completed by the doctors who took part in the trial. To prove the success of the study, three questionnaires were distributed on different occasions. Results Analyzing the answers to the questionnaires, the importance of the handover has come to light and that for the most part, the doctors consider it an essential and irreplaceable moment in daily health care work. Moreover, it became obvious that the use of the handover checklist guaranteed a considerable improvement in the traditional handover in terms of security, completeness, care continuity and clarity. The handover checklist was completely appreciated by the majority of the participant doctors who agree with the definitive introduction of it in their unit. Conclusions Our study indicated the consistency of the handover checklist as an instrument to implement the handover and, indirectly, to improve the quality of the care.

Patient Safety Walkaround: a communication tool for the reallocation of health service resources: An Italian experience of safety healthcare implementation

Abstract The study aims to evaluate the use of Patient Safety Walkaround (SWR) execution model in an Italian Hospital, through the adoption of parametric indices, survey tools, and process indicators. In the 1st meeting an interview was conducted to verify the knowledge of concepts of clinical risk management (process indicators). One month after, the questions provided by Frankel (survey tool) were administered. Each month after, an SWR has been carried trying to assist the healthcare professionals and collecting suggestions and solutions. Results have been classified according to Vincent model and analyzed to define an action plan. The amount of risk was quantified by the risk priority index (RPI). An organizational deficit concerns the management of the operating theatre. A state of intolerance was noticed of queuing patients for outpatient visits. The lack of scheduling of the operating rooms is often the cause of sudden displacements. A consequence is the conflict between patients and caregivers. Other causes of the increase of waiting times are the presence in the ward of a single trolley for medications and the presence of a single room for admission and preadmission of patients. Patients victims of allergic reactions have attributed such reactions to the presence of other patients in the process of acceptance and collection of medical history. All health professionals have reported the problem of n high number of relatives of the patients in the wards. Our study indicated the consistency of SWR as instrument to improve the quality of the care.
