Enhanced Recovery After Surgery (ERAS) Reduces Hospital Costs and Improve Clinical Outcomes in Liver Surgery: a Systematic Review and Meta-Analysis.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are evidence-based, multimodal and patient-centred approach to optimize patient care and experience during their perioperative pathway. It has been shown to be effective in reducing length of hospital stay and improving clinical outcomes. However, evidence on its effective in liver surgery remains weak. The aim of this review is to investigate clinical benefits, cost-effectiveness and compliance to ERAS protocols in liver surgery. METHODS: A systematic literature search was conducted using CINAHL Plus, EMBASE, MEDLINE, PubMed and Cochrane for randomized control trials (RCTs) and cohort studies published between 2008 and 2019, comparing effect of ERAS protocols and standard care on hospital cost, LOS, complications, readmission, mortality and compliance. RESULTS: The search resulted in 6 RCTs and 21 cohort studies of 3739 patients (1777 in ERAS and 1962 in standard care group). LOS was reduced by 2.22 days in ERAS group (MD = -2.22; CI, -2.77 to -1.68; p < 0.00001) compared to the standard care group. Fewer patients in ERAS group experienced complications (RR, 0.71; 95% CI, 0.65-0.77; p = < 0.00001). Hospital cost was significantly lower in the ERAS group (SMD = -0.98; CI, -1.37 to - 0.58; p < 0.0001). CONCLUSION: Our review concluded that the introduction of ERAS protocols is safe and feasible in hepatectomies, without increasing mortality and readmission rates, whilst reducing LOS and risk of complications, and with a significant hospital cost savings. Laparoscopic approach may be necessary to reduce complication rates in liver surgery. However, further studies are needed to investigate overall compliance to ERAS protocols and its impact on clinical outcomes.

Guidelines for Perioperative Care in Elective Colorectal Surgery: Enhanced Recovery After Surgery (ERAS®) Society Recommendations: 2018.

BACKGROUND: This is the fourth updated Enhanced Recovery After Surgery (ERAS®) Society guideline presenting a consensus for optimal perioperative care in colorectal surgery and providing graded recommendations for each ERAS item within the ERAS® protocol. METHODS: A wide database search on English literature publications was performed. Studies on each item within the protocol were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts and examined, reviewed and graded according to Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. RESULTS: All recommendations on ERAS® protocol items are based on best available evidence; good-quality trials; meta-analyses of good-quality trials; or large cohort studies. The level of evidence for the use of each item is presented accordingly. CONCLUSIONS: The evidence base and recommendation for items within the multimodal perioperative care pathway are presented by the ERAS® Society in this comprehensive consensus review.

Thy 3F and 3a malignancy rate, a multisite regional retrospective case series.

Introduction The aim of this study was to ascertain the incidence of thyroid cancer for patients categorised as Thy3, 3a or 3f across four tertiary thyroid multidisciplinary centres in the UK. Material and methods This is a retrospective case series examining patients who presented with a thyroid nodule and diagnosed as Thy3, 3a or 3f according to the Royal College of Pathologists modified British Thyroid Association and Royal College of Physicians Thy system. Results In total, 395 patients were included in this study. Of these, 136 turned out to have benign thyroid disease and 24 had micropapillary thyroid carcinomas. The overall rate of thyroid malignancy was 28.8%. For each subcategory, the rate of malignancy was Thy3 24.7.7%, Thy3a 30.4% and Thy3f 29.2. However, the incidence of thyroid malignancy varied considerably between the four centres (Thy 3f 18-54%). Discussion The diagnosis of thyroid cancer is evolving but detection for malignancy for indeterminate nodules remains below 50% for most centres around the world. In 2014, the British Thyroid Association subdivided the original Thy3 category into Thy3a and Thy3f and recommended a more conservative approach to management for Thy3a nodules. Despite this, only two centres yielded a higher conversion rate of malignancy in the new higher graded Thy3f group compared with Thy3a. Conclusion It is debateable whether the new 'Thy3' subcategories are more useful than the original. Local thyroid malignancy rates may also be more useful than national averages to inform treatment decisions.

Phase III randomized study of the proposed adalimumab biosimilar GP2017 in psoriasis: impact of multiple switches.

BACKGROUND: Adalimumab is used to treat several inflammatory diseases, including plaque psoriasis. GP2017 is a proposed adalimumab biosimilar. OBJECTIVES: To assess the impact of multiple switches between GP2017 and reference adalimumab (ref-ADMB) following the demonstration of equivalent efficacy and similar safety and immunogenicity, in adult patients with active, clinically stable, moderate-to-severe plaque psoriasis. METHODS: This 51-week double-blinded, phase III study randomly assigned patients to GP2017 (n = 231) or ref-ADMB (n = 234) 80 mg subcutaneously at week 0, then 40 mg biweekly from week 1. At week 17, patients were rerandomized to switch (n = 126) or continue (n = 253) treatment. The primary end point was patients achieving ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) at week 16, with equivalence confirmed if the 95% confidence interval (CI) for the difference in PASI 75 between treatments was ± 18%. The key secondary end point was the change from baseline to week 16 in continuous PASI. Other end points were PASI over time; PASI 50, 75, 90 and100; pharmacokinetics; safety; tolerability and immunogenicity for the switched and continued treatment groups. RESULTS: Equivalent efficacy between GP2017 and ref-ADMB was confirmed for the primary (66·8% and 65·0%, respectively; 95% CI -7·46 to 11·15) and key secondary end points (-60·7% and -61·5%, respectively; 95% CI -3·15 to 4·84). PASI improved over time and was similar between treatment groups at week 16, and the switched and continued groups from weeks 17 to 51. There were no relevant safety or immunogenicity differences between GP2017 and ref-ADMB at week 16, or the switched and continued groups from weeks 17 to 51. No hypersensitivity to adalimumab was reported upon switching. CONCLUSIONS: Following the demonstration of GP2017 biosimilarity to ref-ADMB, switching up to four times between GP2017 and ref-ADMB had no detectable impact on efficacy, safety or immunogenicity.

Ensuring patient safety when implementing a new diagnostic pathway for thyroid nodules.

Introduction The aim of this study was to determine whether ultrasound alone is sufficient to safely exclude malignancy in thyroid nodules in a district general hospital setting, to comply with the latest British Thyroid Association guidelines. Methods This retrospective study investigated the quality of ultrasound reporting and the correlation between ultrasound report and histology for individual thyroid nodules. Cases were selected from the thyroid multidisciplinary meeting and included all patients having undergone surgery for a thyroid malignancy in a one-year period. Results Forty-seven patients were included in the study. Ultrasound reports were reviewed and assessed, in which 21 clinicians were involved; 36% of scans included a summary of whether the nodule(s) overall appeared benign, equivocal, suspicious or malignant; 4% of reports included a U classification; 81% of reports commented on cervical lymph nodes. Ultrasound was compared with histology. The sensitivity of ultrasound in correctly identifying nodules requiring further investigation was of 56% and specificity was 81%. Positive predictive value was 81% and negative predictive value was 56%. Discussion These findings suggest that, in a district general hospital setting without a dedicated head and neck radiologist, using only ultrasound and limiting fine-needle aspiration cytology to identify suspicious nodules may not be safe, as a high number of nodules appearing benign on ultrasound may ultimately prove to be malignant.

Randomized open-label phase II study comparing oxycodone-naloxone with oxycodone in early return of gastrointestinal function after laparoscopic colorectal surgery.

BACKGROUND: Combined oral modified-release oxycodone-naloxone may reduce opioid-induced postoperative gut dysfunction. This study examined the feasibility of a randomized trial of oxycodone-naloxone within the context of enhanced recovery for laparoscopic colorectal resection. METHODS: In a single-centre open-label phase II feasibility study, patients received analgesia based on either oxycodone-naloxone or oxycodone. Primary endpoints were recruitment, retention and protocol compliance. Secondary endpoints included a composite endpoint of gut function (tolerance of solid food, low nausea/vomiting score, passage of flatus or faeces). RESULTS: Eighty-two patients were screened and 62 randomized (76 per cent); the attrition rate was 19 per cent (12 of 62), leaving 50 patients who received the allocated intervention with 100 per cent follow-up and retention (modified intention-to-treat cohort). Protocol compliance was more than 90 per cent. Return of gut function by day 3 was similar in the two groups: 13 (48 per cent) of 27 in the oxycodone-naloxone group and 15 (65 per cent) of 23 in the control group (95 per cent c.i. for difference -10·0 to 40·7 per cent; P = 0·264). However, patients in the oxycodone-naloxone group had a shorter time to first bowel movement (mean(s.d.) 87(38) h versus 111(37) h in the control group; 95 per cent c.i. for difference 2·3 to 45·4 h, P = 0·031) and reduced total (oral plus parenteral) opioid consumption (mean(s.d.) 78(36) versus 94(56) mg respectively; 95 per cent c.i. for difference -10·2 to 42·8 mg, P = 0·222). CONCLUSION: High participation, retention and protocol compliance confirmed feasibility. Potential benefits of oxycodone-naloxone in reducing time to bowel movement and total opioid consumption could be tested in a randomized trial. Registration number: NCT02109640 (https://www.clinicaltrials.gov/).

Analysis of the incidence and factors predictive of inadvertent parathyroidectomy during thyroid surgery.

BACKGROUND: Inadvertent (or incidental) parathyroidectomy can occur during thyroidectomy. However, the factors associated with inadvertent parathyroidectomy remain unclear. This study aimed to report the rate of inadvertent parathyroidectomy during thyroidectomy and associated risk factors. METHODS: Variables including fine needle aspiration cytology findings, age, sex, thyroid weight, concurrent neck dissection, extent of thyroidectomy, and the presence of cancer and parathyroid tissue within the specimen were recorded for 266 patients. The incidence of post-operative hypocalcaemia was also recorded. Univariate and multivariate analysis were performed to identify factors associated with inadvertent parathyroidectomy. RESULTS: The inadvertent parathyroidectomy rate was 16 per cent. Univariate analysis revealed that cancer and concurrent neck dissection predicted inadvertent parathyroidectomy. On multivariate analysis, only concurrent neck dissection remained an independent predictor of inadvertent parathyroidectomy: it was associated with a fourfold increase in inadvertent parathyroidectomy. CONCLUSION: The inadvertent parathyroidectomy rate was 16 per cent and concurrent neck dissection was identified as an independent predictor of inadvertent parathyroidectomy.

Preoperative conditioning with oral carbohydrate loading and oral nutritional supplements can be combined with mechanical bowel preparation prior to elective colorectal resection.

OBJECTIVE: Preoperative conditioning with oral fluid and carbohydrate (CHO) loading allows the patient to undergo surgery in the fed state and is associated with reduced postoperative insulin resistance. Further benefit may accrue from oral nutritional supplements (ONS) to counteract the fasting associated with mechanical bowel preparation (MBP). In this study we assess the ability to prescribe, dispense and have patients comply with a protocol combining preoperative ONS and CHO/fluid loading during MBP. METHOD: One hundred and forty-seven patients undergoing elective left colonic or rectal resection were recruited to an Enhanced Recovery after Surgery (ERAS) programme. All patients were prescribed MBP (2 sachets Picolax). On the daytime prior to surgery, eligible patients were prescribed 2 x 200 ml of ONS (Fortijuice, Nutricia) and in the evening 800 ml oral CHO/fluid loading (Preop(R), Nutricia,). Patients were prescribed a further 400 ml of oral/CHO/fluid on the morning of surgery 2 h prior to induction of anaesthesia. Protocol compliance was audited prospectively. RESULTS: One hundred and forty-seven patients received MBP. Twenty-three patients were ineligible for oral CHO/fluid loading [diabetes (n = 22), allergy to lemon flavoured drinks (n = 1)]. Fourteen patients did not receive the preoperative CHO drinks due to failure to prescribe (n = 8) or dispense (n = 6). One hundred and ten patients were dispensed the combined ONS and CHO/fluid loading regimen, compliance rates were 83% with ONS, 80% with CHO/fluid loading and 74% with both. CONCLUSION: Approximately 74% of patients undergoing MBP can comply with preoperative conditioning with ONS and CHO/fluid loading. Prescription and dispensing requires close attention to detail.

Internal carotid artery aneurysm presenting as sinus pain.

Sinusitis and its associated facial pain are frequently seen by ENT surgeons. However, it is important to have a high index of suspicion in cases with atypical symptoms, particularly those with unexplained, unilateral, severe facial pain, and to consider an internal carotid artery dissection. This important diagnosis accounts for almost 20 per cent of all strokes in the young, and anti-coagulation can help to prevent thrombosis and embolism. Two cases are presented for illustration.

Use of laser, otoendoscopy and facial nerve monitoring in otological surgery: United Kingdom survey.

Newer surgical tools, which have been widely accepted as important adjuncts in otological surgery, include the laser, otoendoscopy and facial nerve monitoring. A confidential postal questionnaire survey was carried out to evaluate the usage of these newer techniques among the Consultant members of the British Association of Otorhinolaryngology-Head and Neck Surgery. Our study revealed that the usage of otoendoscopy, laser and/or facial nerve monitoring is not as widespread as might be thought among otological surgeons in the United Kingdom.

Informed consent for middle ear operations: a United Kingdom survey.

Otorhinolaryngologists throughout the UK routinely perform middle ear operations. Although the risk of serious complications in the hands of a well-trained surgeon is very low, some of the complications of middle ear surgery are devastating to the patient viz. facial nerve palsy and complete hearing loss. The subject of informed consent is highly topical because of clinical governance and medico-legal implications. We have audited the practice of the Consultant members of the British Association of Otorhinolaryngologists-Head and Neck Surgeons via a postal questionnaire with regards to their consenting process prior to middle ear operations. Our study looked at the practice of discussing different complications and the complication rates, the person consenting, time spent on consenting, and the documentation. We found that wide variations exist in the consenting process. The implications of the results are discussed. This study is particularly pertinent at the present time with the implementation of the new consenting standards document published by the Department of Health.

Group C streptococci isolated from throat swabs: a laboratory and clinical study.

AIMS: To determine the prevalence of beta haemolytic, Lancefield group C streptococci in throat swabs taken in routine clinical practice, and correlate the species identified with presenting clinical features. METHODS: One year, laboratory based prospective study, using a questionnaire to elicit clinical information. RESULTS: 4.4% of throat swabs yielded group C streptococci, of which 38% belonged to S equisimilis and 53% to S anginosus-milleri group (SAM). Pyrexia was more common in patients with S equisimilis, but other clinical features did not differ significantly between the two groups. No S zooepidemicus was isolated. CONCLUSIONS: Species identification of group C streptococci from throat swabs does not appear to be clinically useful in this patient population. However, the prevalence and spectrum of organisms is similar to that reported in N America, where studies suggest a possible role in some cases of severe pharyngitis. Observational studies such as this lack power to resolve the issue of pathogenicity, for which a placebo controlled trial of antibiotic treatment is ideally required.

Convalescent excretion of Salmonella enteritidis in infants.

OBJECTIVES: To review the excretion of Salmonella enteritidis PT4 in the faeces of infants involved in a point-source outbreak in a nursery, and to relate these findings to advice given by the Outbreak Control Team (OCT). METHODS: Retrospective laboratory-based survey. RESULTS: Infection with S. enteritidis PT4 was microbiologically confirmed in 33 primary cases and one secondary case. Of the faeces submitted 4 weeks from exposure, 96% remained positive. None of the infants was symptomatic by this time, and none received antimicrobial treatment. Two infants aged less than 1 year were still excreting 22 weeks after the onset of the outbreak. CONCLUSIONS: As for other serotypes, S. enteritidis PT4 causes prolonged symptomless excretion after infection, particularly in infants aged less than 1 year. Infection control measures, including exclusion criteria, may need to be modified as an outbreak progresses.

Wound care. Discharged but not forgotten.

A pilot study assessed a methodology for establishing the incidence of post-discharge surgical wound infections. An infection rate of 13% was recorded. The eight patients who developed infections generated 35 clinical episodes. This could have resource implications for early discharge after surgery.
