A systematic review and meta-analysis of the efficacy of topical sphincterotomy treatments for anal fissure.

BACKGROUND: Anal fissure is a common condition that can be treated medically or surgically. Chemical sphincterotomy is often used before surgical intervention. This study aims to evaluate the effectiveness of topical agents for chemical sphincterotomy on healing of anal fissures and side-effects. METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) compliant systematic review was performed using MEDLINE, EMBASE, Scopus, and CENTRAL databases. Eligible studies included randomized controlled trials which compared topical sphincterotomy agents with topical placebo agents or each other. Studies that included surgical treatments were excluded. Overall evidence was synthesized according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS: Thirty-seven studies met the study selection criteria. Seventeen studies show that glyceryl trinitrate (GTN) was significantly more likely to heal anal fissure than placebo (relative risk (RR) = 1.96, 95% confidence interval (95%CI) = 1.35-2.84, I2 = 80%). Eleven studies showed a marginally significant difference between healing rates for diltiazem vs GTN, RR = 1.16, (1.01-1.33) I2 = 48%. There was no significant difference in healing between diltiazem and placebo, RR = 1.65, (0.64-4.23), I2 = 92%. GTN significantly reduced pain on the visual analog scale compared to the placebo group, MD-0.97 (-1.64 to -0.29) I2 = 92%. There was high certainty of evidence that GTN was significantly more likely to cause headache than placebo (RR = 2.73 (1.82-4.10) I2 = 58%) and diltiazem RR = 6.88 (2.19-21.63) I2 = 17%. CONCLUSION: There is low certainty evidence topical nitrates are an effective treatment for anal fissure healing and pain reduction compared to placebo. Despite widespread use of topical diltiazem, more evidence is required to establish the effectiveness of calcium channel blockers compared to placebo.

Local Anaesthesia Alone Versus Regional or General Anaesthesia in Excisional Haemorrhoidectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Excisional haemorrhoidectomy has been traditionally performed under general or regional anaesthesia. However, these modes are associated with complications such as nausea, urinary retention and motor blockade. Local anaesthesia (LA) alone has been proposed to reduce side effects as well as to expedite ambulatory surgery. This systematic review aims to assess LA versus regional or general anaesthesia for excisional haemorrhoidectomy. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE, EMBASE and CENTRAL databases were searched to 13 January 2020. All randomised controlled trials comparing LA only versus regional or general anaesthesia in patients who received excisional haemorrhoidectomy were included. The main outcomes included pain, adverse effects and length of stay. RESULTS: Nine trials, consisting of six studies comparing local versus regional anaesthesia and three comparing LA versus general anaesthesia, were included. Meta-analysis showed a significantly lower relative risk for need of rescue analgesia (RR 0.32 [95% CI 0.16-0.62]), intra-operative hypotension (RR 0.17 [95% CI 0.04-0.76]), headache (RR 0.13 [0.02-0.67]) and urinary retention (RR 0.17 [95% CI 0.09-0.29]) for LA when compared with regional anaesthesia. There was mixed evidence for both regional and general anaesthesia in regard to post-operative pain. CONCLUSIONS: LA alone may be considered as an alternative to regional anaesthesia for excisional haemorrhoidectomy with reduced complications and reduction in the amount of post-operative analgesia required. The evidence for LA compared to general anaesthesia for haemorrhoidectomy is low grade and mixed.

Health economics in Enhanced Recovery After Surgery programs.

PURPOSE: The Enhanced Recovery After Surgery (ERAS) program aims to combine and coordinate evidence-based perioperative care interventions that support standardizing and optimizing surgical care. In conjunction with its clinical benefits, it has been suggested that ERAS reduces costs through shorter convalescence and reduced morbidity. Nevertheless, few studies have evaluated the cost-effectiveness of ERAS programs. The aim of this systematic review, therefore, is to evaluate the claims that ERAS is cost-effective and to characterize how these costs were reported and evaluated. SOURCE: The electronic databases, MEDLINE(®) and EMBASE™, were searched from inception to April 2014. PRINCIPAL FINDINGS: Seventeen studies met the inclusion criteria and were included for review. Enhanced Recovery After Surgery protocols in various abdominal surgeries have been investigated, including colorectal, bariatric, gynecological, gastric, pancreatic, esophageal, and vascular surgery. All studies reported cost savings associated with hastening recovery and reducing morbidity and complications. All studies included in this review focused primarily on in-hospital costs, with some attempting to account for readmission costs and follow-up services. In all but two studies, the breakdown of cost data for the individual studies was poorly detailed. CONCLUSIONS: In conclusion, ERAS protocols appear to be both clinically efficacious and cost effective across a variety of surgical specialties in the short term. Nevertheless, studies reporting out-of-hospital cost data are lacking. Further research is required to determine how best to evaluate both medium- and long-term costs relating to ERAS pathways while taking quality of life data into account.

A history of the treatment of appendicitis in children: lessons learned.

During the latter half of the 19th century, surgeons increasingly reported performing appendicectomies. Fitz from Harvard, Groves from Canada and Tait from Britain all recorded successful removal of the appendix. McBurney described the point of maximal tenderness in classic appendicitis and also the muscle-splitting incision centred on this point. Priority is given to McArthur in describing the lateral muscle-splitting incision. The direction of the cutaneous incision was later modified by Elliott and Lanz. Incisions that healed well were essential to recovery. Appendicectomy became a 'fashionable' operation after the London surgeon, Treves, removed the appendix of King Edward VII. Through the 20th century, the mortality from appendicitis fell notably with the advent of sulphonamide and penicillin, improvements in fluid therapy and safer anaesthesia. By 1990, diagnostic delay was the main cause of death. Semm performed the first laparoscopic appendicectomy in 1990, roundly criticized at the time for what is now a routine procedure. We view contemporary debates on the indications for appendicectomy, the best approach and how to optimize recovery in the light of the history of this intriguing disease.

Efficacy of general practitioners with specialty interests for surgical procedures.

BACKGROUND: General practitioners with specialty interests (GPwSIs) have been an emerging entity in the last decade or so and aim to improve patient's access to specialist level care in the primary care setting. This is achieved by them providing equivalent quality and outcomes to secondary consultant-led services, while not necessarily providing the same breadth of clinical care as them. In this systematic review, we attempt to address their efficacy for surgical procedures and specialties. METHODS: PRISMA guidelines were followed and an electronic literature search was performed independently by two authors using predefined search terms across EMBASE, Ovid MedLine, PubMed, PSYCINFO and the Cochrane Library databases. A total of 817 articles were reviewed after which only six were included for the systematic review. RESULTS: Of the six articles selected, three studies analysed efficacy of GPwSIs with regard to surgical excision of skin lesions. One study looked at the economic evaluation of a GPwSI-led dermatology service in primary care and included GPwSIs carrying out skin excisions. The remaining two included studies were from the same institution and evaluated hernia repairs at a single centre general practitioner practice. CONCLUSION: There is generally, a paucity of evidence looking at the efficacy of GPwSIs for surgical procedures. While they seem to provide an acceptable standard of specialist care in the primary care setting, they do not appear to save money. However, they provide an alternative workforce and the improved access to care that results from it may offset their higher costs.

Chewing gum and postoperative ileus in adults: a systematic literature review and meta-analysis.

INTRODUCTION: Post-operative ileus (POI) is a major problem following elective abdominal surgery. Several studies have been published investigating the use of chewing gum to reduce POI. These studies however, have produced variable results. Thus, there is currently no consensus on whether chewing gum should be widely instituted as a means to help reduce POI. METHODS: We performed a systematic literature review to evaluate whether the use of chewing gum post-operatively improves POI in abdominal surgery. A comprehensive review of the literature was conducted according to the guidelines in the PRISMA statement. The following databases were searched: MEDLINE, PUBMED, EMBASE, SCOPUS, Science Direct, CINAHL and the Cochrane Central Register of Controlled Trials. Clinical outcomes were extracted and meta-analysis was performed. RESULTS: There were 1019 patients from 12 randomised controlled studies included in this review. Only one study was conducted in an Enhanced Recovery after Surgery (ERAS) environment. Seven of the twelve studies concluded that chewing gum reduced post-operative ileus. The remaining five studies found no clinical improvement. Overall, there was a small benefit in reducing time to flatus, and time to bowel motion, but no difference in the length of stay or complications. CONCLUSION: Chewing gum offers only a small benefit in reducing time to flatus and time to passage of bowel motion following abdominal surgery. This benefit is of limited clinical significance. Further studies should be conducted in a modern peri-operative care environment.

Intraperitoneal local anaesthetic in abdominal surgery - a systematic review.

BACKGROUND: The use of intraperitoneal local anaesthetic (IPLA) can be used to modulate visceral nociception after abdominal surgery; however, this technique is not routinely used in open abdominal surgery. The aim of this systematic review was to appraise the clinical effects of IPLA in open abdominal surgery for metachronous outcomes including pain, metabolic response to surgery and gastrointestinal function. METHODS: A comprehensive search was conducted independently without language restriction. Relevant meeting abstracts and reference lists were manually searched. Data analysis was performed using Review Manager Version 5.0 software. Post-operative clinical and metabolic outcomes of randomized controlled trials comparing IPLA versus no IPLA or placebo solution were used for meta-analysis. RESULTS: Twelve trials were identified including eight randomized trials in gastrointestinal and gynaecological surgery. Post-operative pain was reduced but not opioid use. There was blunting of postoperative hyperglycaemia. There was no difference in post-operative cortisol response. Return of bowel function appeared to be quickened, although meta-analysis was not possible. CONCLUSION: The use of IPLA is safe and appears to have clinical benefits. However this technique has not been studied in optimized perioperative settings. Trials are needed to evaluate this method of visceral blockade further after major abdominal surgery.

The quality of life of New Zealand doctors and medical students: what can be done to avoid burnout?

Life as a doctor or medical student poses particular challenges and stressors which can impact on quality of life. This paper sets out to review what is known about the quality of life of doctors and medical students and the ramifications of a poor quality of life. This paper summarises the national and international literature on what is known about quality of life and burnout with regards to both medical students and doctors in terms of the origin of these issues and various risk factors. This paper further recommends ways of addressing these issues from an undergraduate level, for doctors in practice, and then in the workplace. It is critical that the New Zealand medical workforce addresses these issues in a timely manner. In addition, the paper proposes that if doctors, particularly those involved as clinical teachers, have a poor quality of life, the learning environment for medical students may be adversely affected. Exploration of the evidence around these important issues and their relevance to the New Zealand context are considered with suggested solutions.

Optimization of perioperative care for colonic surgery: a review of the evidence.

Enhanced recovery after surgery (ERAS) care pathways are becoming increasingly common in colonic surgery. ERAS is a combination of individual strategies that have been shown to be effective in improving care. In this article, we review the evidence surrounding core components of enhanced recovery care pathways for patients undergoing open colonic surgery. We will also identify new elements that should be considered as part of ERAS strategy.
