Factors affecting clinic attendance for children referred with middle ear conditions.

BACKGROUND: Middle ear disease is common in children and, if untreated, can lead to long term complications. This study investigated whether ethnic or socioeconomic inequities existed among children referred to a tertiary regional paediatric ORL service. METHODS: All middle ear pathology related referrals to Starship Children's Hospital ORL service during 2018 and 2019 were reviewed. Online clinical records were accessed to collect demographic data and appointment outcomes. The relationships between ethnicity, socioeconomic status, age at referral and clinic attendance were analysed. RESULTS: A total of 1530 children were referred and 214 (14.0%) of these did not attend their scheduled appointments. Compared with the age of referral for European children, Maori children were referred on average 1.1 years older while Pasifika children were referred 2.4 years older. Compared to European children, Maori children were 4.3 times more likely to miss an appointment while Pasifika were 7.2 times more likely. Socioeconomic status had no significant effect on either age of referral or clinic attendance. CONCLUSIONS: Maori and Pasifika children with middle ear disease are referred later and are more likely to miss outpatient clinic appointments. Pasifika children are affected more than Maori.

Intravenous Local Anesthetic Compared With Intraperitoneal Local Anesthetic in Laparoscopic Colectomy: A Double-blind Randomized Controlled Trial.

INTRODUCTION: Controlling perioperative pain is essential to improving patient experience and satisfaction following surgery. Traditionally opioids have been frequently utilized for postoperative analgesia. Although they are effective at controlling pain, they are associated with adverse effects, including postoperative nausea, vomiting, ileus, and long-term opioid dependency.Following laparoscopic colectomy, the use of intravenous or intraperitoneal infusions of lidocaine (IVL, IPL) are promising emerging analgesic options. Although both techniques are promising, there have been no direct, prospective randomized comparisons in patients undergoing laparoscopic colon resection. The purpose of this study was to compare IPL with IVL. METHODS: Double-blinded, randomized controlled trial of patients undergoing laparoscopic colonic resection. The 2 groups received equal doses of either IPL or IVL which commenced intra-operatively with a bolus followed by a continuous infusion for 3 days postoperatively. Patients were cared for through a standardized enhanced recovery after surgery program. The primary outcome was total postoperative opioid consumption over the first 3 postoperative days. Patients were followed for 60 days. RESULTS: Fifty-six patients were randomized in a 1:1 fashion to the IVL or IPL groups. Total opioid consumption over the first 3 postoperative days was significantly lower in the IPL group (70.9 mg vs 157.8 mg P < 0.05) and overall opioid consumption during the total length of stay was also significantly lower (80.3 mg vs 187.36 mg P < 0.05. Pain scores were significantly lower at 2 hours postoperatively in the IPL group, however, all other time points were not significant. There were no differences in complications between the 2 groups. CONCLUSION: Perioperative use of IPL results in a significant reduction in opioid consumption following laparoscopic colon surgery when compared to IVL. This suggests that the peritoneal cavity/compartment is a strategic target for local anesthetic administration. Future enhanced recovery after surgery recommendations should consider IPL as an important component of a multimodal pain strategy following colectomy.

Topical Versus Oral Metronidazole After Excisional Hemorrhoidectomy: A Double-Blind Randomized Controlled Trial.

BACKGROUND: Both topical and oral metronidazole have been shown to reduce pain after excisional hemorrhoidectomy. Although recent meta-analyses have demonstrated efficacy against placebo, there has been no comparison between the 2 routes. OBJECTIVE: This study aims to investigate whether topical or oral metronidazole provides the most analgesic properties after excisional hemorrhoidectomy. DESIGN: A prospective, double-blind, randomized controlled trial was performed. SETTING: This trial was conducted at 2 hospitals in New Zealand between March 2019 and February 2020. PATIENTS: Adults undergoing elective excisional hemorrhoidectomy for grade III/IV hemorrhoids were randomized. INTERVENTIONS: Participants were randomized to receive either topical metronidazole ointment and an oral placebo versus oral metronidazole with a placebo ointment for 7 days. MAIN OUTCOME MEASURES: The primary outcome was daily pain scores for 7 days, estimated using a generalized linear mixed model fitted with time and treatment arm and tested for interaction with time and treatment arm. Secondary outcomes included additional analgesia, return to normal activity, recovery scores, and adverse effects. RESULTS: A total of 120 participants were included, with 60 in each group. A unimodal peak of pain was recorded with the maximum at days 3 and 4, but there was no significant difference in resting pain scores, with a mean difference at day 3 of 0.47 (-0.48, 1.42). There were no significant differences for secondary outcomes. Fourteen (11.7%) participants were readmitted, without significant difference between groups. Fifty-nine percent of participants preferred topical analgesic compared with 31% who preferred oral and 9.7% who had no preference. LIMITATIONS: This was a pragmatic study in which we could not have stopped participants seeking other analgesics and with less than perfect complete compliance. CONCLUSION: Postoperative oral and topical metronidazole provide similar analgesia after excisional hemorrhoidectomy. The route should depend on patient preference, with topical administration potentially benefiting from improved antimicrobial stewardship and having less effect on the gut microbiome.

ANTECEDENTES: Se ha demostrado que tanto el metronidazol tópico como el oral reducen el dolor después de una hemorroidectomía por escisión. Aunque los metaanálisis más recientes han demostrado eficacia frente al placebo, no ha habido comparación entre las dos vías. OBJETIVO: Este estudio tiene como objetivo investigar si el metronidazol tópico u oral proporciona las propiedades más analgésicas después de una hemorroidectomía por escisión. DISEO: Se realizó un ensayo prospectivo, controlado, aleatorio, a doble ciego. AJUSTE: Este ensayo fue realizado en dos hospitales de Nueva Zelanda entre marzo de 2019 y febrero de 2020. PACIENTES: Se asignaron al azar pacientes adultos sometidos a hemorroidectomía por escisión electiva por hemorroides de grado III / IV. INTERVENCIONES: Los participantes fueron asignados al azar para recibir un ungüento de metronidazol tópico y un placebo oral versus metronidazol oral con un ungüento de placebo durante siete días. PRINCIPALES MEDIDAS DE RESULTADO: El resultado primario fueron las puntuaciones diarias de dolor durante siete días, estimadas mediante un modelo lineal mixto generalizado ajustado tanto con el tiempo y el brazo de tratamiento y probado para la interacción con el tiempo y el brazo de tratamiento. Los resultados secundarios incluyen analgesia adicional, retorno a la actividad normal, puntuaciones de recuperación y efectos adversos. RESULTADOS: Se incluyó un total de 120 participantes, 60 en cada grupo. Se registró un pico de dolor unimodal con el máximo en los días 3 y 4, pero no hubo diferencias significativas en las puntuaciones de dolor en reposo, con una diferencia media en el día 3 de 0,47 (-0,48, 1,42). No hubo diferencias significativas para los resultados secundarios. Catorce (11,7%) participantes fueron readmitidos, sin diferencias significativas entre los grupos. El cincuenta y nueve por ciento de los participantes prefirió el tópico, en comparación con el 31% por vía oral y el 9,7% sin preferencia. LIMITACIONES: Este fue un estudio pragmático en el que no pudimos haber impedido que los participantes buscaran otros analgésicos, con un cumplimiento completo menos que perfecto. CONCLUSINES: El metronidazol posoperatorio por vía oral o tópica proporciona una analgesia similar después de una hemorroidectomía por escisión. La vía debe depender de la preferencia del paciente, y la administración tópica se beneficia potencialmente por una mejor protección de los antimicrobianos y un menor efecto sobre el microbioma intestinal.

Equity of colonoscopy provision and quality in Maori and New Zealand Europeans: a comparative retrospective study.

BACKGROUND: High-quality colonoscopy is essential for investigating suspected colorectal cancer and relies on endoscopists meeting key performance indicator (KPI) targets. The rising demand for colonoscopy raises concerns that Maori populations could be under-served. This study aimed to compare rates of colonoscopy provision and colonoscopy KPIs between Maori and New Zealand (NZ) European patients. METHODS: This retrospective comparative study was conducted at Whanganui Hospital (NZ). Consecutive colonoscopies performed between September 2016 and March 2020 were included. Primary outcome was the rate of colonoscopy provision for the population. Secondary outcomes were the colonoscopy completion rate (CCR), colonoscope withdrawal time (CWT), polyp detection rate (PDR) and adenoma detection rate (ADR). Subgroup analysis of ADR in index symptomatic colonoscopies was also performed. RESULTS: A total of 2962 colonoscopies were analysed (385 Maori; 2577 NZ European). Rates of colonoscopy provision in participants aged ≥40 were significantly lower among Maori (6.1% versus 9.1%; P < 0.0001). The CCR (P = 1.00), CWT (P = 0.28) and PDR (P = 0.24) were similar. Whilst the ADR in the overall cohort was significantly lower in Maori (32.7% versus 40.0%; P = 0.028), this was not observed when stratified by 10-year age cohorts. The ADR was similar on subgroup analysis of index symptomatic colonoscopies (P = 0.42). CONCLUSIONS: This study found inequities in access to colonoscopy services for Maori compared to NZ European patients. Among those that did receive colonoscopy, there were no differences in colonoscopy quality after age stratification. Improving equity will require the addition of colonoscopy provision rates to other mandatory KPIs and reporting these by ethnicity in all endoscopy units.

A non-opioid analgesic implant for sustained post-operative intraperitoneal delivery of lidocaine, characterized using an ovine model.

Appropriate management of post-operative pain is an ongoing challenge in surgical practice. At present, systemic opioid administration is routinely used for analgesia in the post-operative setting. However, due to significant adverse effects and potential for misuse, there is a perceived need for the development of alternative, opioid-sparing treatment modalities. Continuous infusion of local anesthetic into the peritoneum after major abdominal surgery reduces pain and opioid consumption, and enhances recovery from surgery. Here we describe a non-opioid, poly(ethylene-co-vinyl-acetate) intraperitoneal implant for the sustained delivery of local anesthetic following major abdominal surgery. A radio-opaque core had the required mechanical strength to facilitate placement and removal procedures. This core was enclosed by an outer shell containing an evenly dispersed local anesthetic, lidocaine. Sustained release of lidocaine was observed in an ovine model over days and the movement modelled between peritoneal fluid and circulating plasma. While desirably high levels of lidocaine were achieved in the peritoneal space these were several orders of magnitude higher than blood levels, which remained well below toxic levels. A pharmacokinetic model is presented that incorporates in vitro release data to describe lidocaine concentrations in both peritoneal and plasma compartments, predicting similar release to that suggested by lidocaine concentrations remaining in the device after 3 and 7 days in situ. Histological analysis revealed similar inflammatory responses following implantation of the co-extruded implant and a commercially used silicone drain after three days. This non-opioid analgesic implant provides sustained release of lidocaine in an ovine model and is suitable for moving onto first in human trials.

Risk factors for mortality after emergency laparotomy: scoping systematic review.

BACKGROUND: Emergency laparotomy (EL) is a common procedure with high mortality leading to several efforts to record and reduce mortality. Risk scores currently used by quality improvement programmes either require intraoperative data or are not specific to EL. To be of utility to clinicians/patients, estimation of preoperative risk of mortality is important. We aimed to explore individual preoperative risk factors that might be of use in developing a preoperative mortality risk score. METHODS: Two independent reviewers identified relevant articles from searches of MEDLINE, EMBASE and Cochrane databases from January 1980 to January 2018. We selected studies that evaluated only preoperative predictive factors for mortality in EL patients. RESULTS: The search yielded 6648 articles screened, with 22 studies included examining 157 728 patients. The combined post-operative 30-day mortality was 13%. All, but one small study, were at low risk of bias. A meta-analysis of results was not possible due to the heterogeneity of populations and outcomes. Age, American Society of Anesthesiologists, preoperative sepsis, dependency status, current cancer and comorbidities were associated with increased mortality. Acute physiological derangements seen in renal, albumin and complete blood count assays were strongly associated with mortality. Delay to surgery and diabetes did not influence mortality. Higher body mass index was protective. CONCLUSION: Preoperatively, risk factors identified can be used to develop and update risk scores specific for EL mortality. This scoping review focused on the preoperative setting which helps tailor treatment decisions. It highlights the need for further research to test the relevance of newer risk factors such as frailty and nutrition.

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.

Evaluating and improving current risk prediction tools in emergency laparotomy.

PURPOSE: Emergency laparotomy (EL) encompasses a high-risk group of operations, which are increasingly performed on a heterogeneous population of patients, making preoperative risk assessment potentially difficult. The UK National Emergency Laparotomy Audit (NELA) recently produced a risk predictive tool for EL that has not yet been externally validated. We aimed to externally validate and potentially improve the NELA tool for mortality prediction after EL. METHODOLOGY: We reviewed computer and paper records of EL patients from May 2012 to June 2017 at Middlemore Hospital (New Zealand). The inclusion criteria mirrored the UK NELA. We examined the NELA, Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality (P-POSSUM), Acute Physiology and Chronic Health Evaluation II (APACHE-II), and American College of Surgeons National Surgical Quality Improvement Programs risk predictive tools for 30-day mortality. The Hosmer-Lemeshow test was used to assess calibration, and the c statistic, to evaluate discrimination (accuracy) of the tools. We added the modified frailty index (mFI) and nutrition to improve the accuracy of risk predictive tools. RESULTS: A total of 758 patients met the inclusion criteria, with an observed 30-day mortality of 7.9%. The NELA was the only well calibrated tool, with predicted 30-day mortality of 7.4% (p = 0.22). When combined with mFI and nutritional status, the c statistic for NELA improved from 0.83 to 0.88. American College of Surgeons National Surgical Quality Improvement Programs, APACHE-II, and P-POSSUM had lower c statistics, albeit also showing an improvement (0.84, 0.81, and 0.74, respectively). CONCLUSION: We have demonstrated the NELA tool to be most predictive of mortality after EL. The NELA tool would therefore facilitate preoperative risk assessment and operative decision making most precisely in EL. Future research should consider adding mFI and nutritional status to the NELA tool. LEVEL OF EVIDENCE: Level IV; Retrospective observational cohort study.

Association between perioperative intraperitoneal local anaesthetic infusion and long-term survival and cancer recurrence after colectomy: follow-up analysis of a previous randomized controlled trial.

BACKGROUND: High concentrations of local anaesthetic have an anti-proliferative effect on colonic cancer in vitro. Intraperitoneal local anaesthetic (IPLA) has shown analgesic benefit and improved recovery in the perioperative setting. The long-term effects of IPLA in colon cancer resection have not been examined. This study aims to review the survival and oncological outcomes of a previously conducted trial that compared perioperative IPLA with placebo. METHODS: Sixty patients underwent colonic resection for benign and malignant disease as part of a double-blinded, randomized, placebo-controlled study between September 2008 and November 2009. The IPLA group received instillation of intraperitoneal ropivacaine before dissection followed by a 3-day infusion. The placebo group was treated identically but with 0.9% saline solution. A follow-up analysis was conducted to evaluate overall survival, disease-free survival and recurrence specifically for patients undergoing resection for stages I-III colon cancer. Kaplan-Meier analysis was performed, and the log-rank test was used to evaluate difference in survival between groups. RESULTS: Thirty-seven of the 60 patients had stages I-III colon cancer and were included in this analysis. Nineteen patients were in the placebo group. There was no significant difference in overall survival or all-cause mortality. There was a higher incidence of cancer-specific mortality in the local anaesthetic group (P < 0.046). CONCLUSION: It does not appear that IPLA is associated with a significant survival benefit in patients with colonic malignancy undergoing colectomy. Other studies are needed to analyse the long-term outcomes.

Topical analgesia following excisional haemorrhoidectomy: a systematic review and meta-analysis of randomised controlled trials.

PURPOSE: Post-operative pain following excisional haemorrhoidectomy poses a particular challenge for patient recovery, as well as a burden on hospital resources. There appears to be an increasing role for topical agents to improve this pain, but their efficacy and safety have not been fully assessed. This systematic review aims to assess all topical agents used for pain following excisional haemorrhoidectomy. METHODS: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two authors independently assessed MEDLINE, EMBASE, and CENTRAL databases to 27 June 2019. All randomised controlled trials (RCTs) in English that investigated topical agents following excisional haemorrhoidectomy were included. Meta-analysis was performed using Review Manager, version 5.3. RESULTS: A total of 3639 records were identified. A final 32 RCTs were included in the qualitative analysis. Meta-analysis was performed on 9 RCTs that investigated glyceryl trinitrate (GTN) (5 for diltiazem, 2 for metronidazole and 2 for sucralfate). There were mixed significant changes in pain for GTN compared with placebo. Diltiazem resulted in significant reduction of pain on post-operative days 1, 2, 3 and 7 (p < 0.00001). Metronidazole resulted in significant reduction of pain on days 1 (p = 0.009), 7 (p = 0.002) and 14 (p < 0.00001). Sucralfate resulted in signification reduction of pain on days 7 and 14 (both p < 0.00001). CONCLUSION: Topical diltiazem, metronidazole and sucralfate appear to significantly reduce pain at various timepoints following excisional haemorrhoidectomy. GTN had mixed evidence. Several single trials identified other promising topical analgesics.

Diagnostic accuracy of procalcitonin for the early diagnosis of anastomotic leakage after colorectal surgery: a meta-analysis.

BACKGROUND: Anastomotic leakage (AL) is a dreaded complication following colorectal surgery. Procalcitonin is one of many biomarkers studied and research has suggested that it has improved accuracy for the diagnosis of AL compared with other inflammatory biomarkers such as C-reactive protein. This meta-analysis was conducted to evaluate the accuracy of procalcitonin in the early diagnosis of AL following colorectal surgery. METHODS: MEDLINE, Embase and PubMed were searched for studies evaluating procalcitonin in the context of AL following colorectal surgery in the elective setting. The literature was reviewed using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Quality of the studies was assessed using the Quality Assessment Diagnostic Accuracy Studies (QUADAS)-2 tool. Meta analyses were conducted using area under the receiver operating characteristic curves for day 3, 4 and 5 post-surgery as a diagnostic test to detect AL. RESULTS: A total of eight studies were analysed. Results showed that the highest diagnostic accuracy for procalcitonin is on day 5 post surgery. The reported optimal cut-off values ranged from 0.25 to 680 ng/mL from postoperative day 3 to 5, with reported negative predictive values ranging from 95% to 100%, and positive predictive values of up to 34%. The highest area under the receiver operating characteristic curve was 0.88 on postoperative day 5. CONCLUSION: Procalcitonin is a useful negative test for AL following elective colorectal surgery. However, as an isolated test, it is not useful in detecting AL.

Intraperitoneal Tramadol in Abdominal Surgery: A Systematic Review.

BACKGROUND: Multimodal analgesic regimes are required to treat pain. Intraperitoneal (IP) agents, such as local anesthetics (LAs), have been shown to reduce pain after abdominal surgery. Other IP analgesics have been tested in several randomized control trials (RCTs), but no reviews or guidelines have evaluated their use. Tramadol is an effective oral and intravenous analgesia with recent evidence supporting the use of IP tramadol (IPT). We aimed to review the efficacy of IPT as an adjunct to intraperitoneal local anesthetics (IPLAs) for pain relief after abdominal surgery. MATERIALS AND METHODS: Relevant articles were identified by two independent reviewers from MEDLINE, EMBASE and PubMed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines up to January 2019. Only RCT comparing IPT + IPLA with IPLA alone were included. Outcomes recorded were the postoperative analgesic requirement, pain scores at 4 h and 24 h and adverse events. Data were analyzed with Review Manager, version 5.3. RESULTS: A total of five RCTs (4× laparoscopic cholecystectomy and 1× abdominal hysterectomy) were included in this review from 419 studies screened. All doses were given as a single bolus. Pain relief requirements over the first 24 h weres less in the IPT + IPLA groups when compared with those in IPLA alone. Pain scores were less for IPT + IPLA groups at 4 h and 24 h. There were no significant differences in adverse events between groups. CONCLUSIONS: In summary, IPT, in combination with IPLA, is effective in the management of acute postoperative pain and reduces the total amount of pain relief consumed in the first 24 h after surgery. Studies reporting the use of IPT + IPLA reported no toxicity or systemic adverse events. Further research into standardizing the dosing of IPT to optimize its effectiveness and further reduce the additional analgesic requirement is indicated.

The impact of computed tomography-assessed sarcopenia on outcomes for trauma patients - a systematic review and meta-analysis.

INTRODUCTION: Sarcopenia is the progressive loss of skeletal muscle mass, strength and general decline in function associated with age, and has previously been shown to be a predictor of poor outcomes following surgery. Computed tomography (CT)-assessed sarcopenia has been proposed to be an independent predictor of outcomes for trauma patients. This systematic review aims to determine the impact of CT-assessed sarcopenia on patient mortality following trauma. MATERIALS AND METHODS: A systematic review and meta-analysis of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. EMBASE, MEDLINE and CENTRAL databases were searched from database inception to 26 November 2018. Bibliographies of included articles were hand searched for potential articles. All observational studies which included trauma patients who had skeletal muscle mass or density assessed by CT were included in the review. Two authors independently performed the search with decisions reached by consensus. Meta-analysis was performed using Review Manager v5.3 using a random effects model. The primary outcome was all cause mortality, as established a priori. RESULTS: Following an initial search of 1984 records, a total of 20 retrospective observational studies were included for qualitative analysis. Ten of these studies consisting of a pooled, partly-overlapping, 2867 patients were included in the meta-analysis. There was a wide variation in the reported prevalence of sarcopenia (25.0-71.1%). Sarcopenia patients were at a significantly increased risk of mortality during inpatient stay (RR 1.96 [95%CI 1.30-2.94], p =  0.001), at 30 days (RR 1.60 [95%CI 1.21-2.13], p =  0.001) and at 1-year (RR 3.11 [95%CI 1.94-4.96], p <  0.00001). There was no significant difference in total complications encountered, ICU duration or total inpatient stay. CONCLUSION: Sarcopenia identified by CT is associated with increased risk of inpatient, 30-day, and 1-year mortality in trauma patients.

Day case versus inpatient stay for excisional haemorrhoidectomy.

BACKGROUND: Excisional haemorrhoidectomy has traditionally been performed on an inpatient basis due to concerns over post-operative pain and urinary retention. Day case procedures are increasingly common. This study aims to investigate readmission rates following day case compared with inpatient haemorrhoidectomy. METHODS: A retrospective cohort review of all haemorrhoidectomies performed at Counties Manukau District Health Board, Auckland from January 2012 to December 2017 was queried from the hospital database. Readmission rates, reason for readmission, time to represent and length of stay within 30 days were recorded. Continuous data were analysed using Mann-Whitney U and Student's t-tests. Categorical data were analysed using the Fisher's exact and chi-squared tests. RESULTS: A total of 485 cases of excisional haemorrhoidectomy were performed, with 62 (12.8%) readmissions within 30 days. There were 170 patients who were treated as day cases with 19 (11.2%) readmissions; 315 patients stayed one night or longer with 43 (13.7%) readmissions (P = 0.97). The demographics of both groups were similar. Pain and bleeding were the most common reasons for readmission in both groups. There were no significant differences between rates of readmission, length of stay following readmission and time to readmission between day case and inpatient groups. CONCLUSIONS: Day case surgery should be considered as an alternative to inpatient surgery for excisional haemorrhoidectomy and can be achieved without increase in hospital readmissions.

Paediatric Osteomyelitis in Fiji.

INTRODUCTION: Osteomyelitis can lead to significant morbidity and long-term disability if early treatment is not initiated in a timely manner. For developing countries this can lead to a significant burden on the healthcare system. This study aims to describe the demographic variables, aetiology and outcomes of treatment and to calculate the incidence of paediatric osteomyelitis in Fiji. The micro-organism profile and the outcomes for treatment were analysed. METHODS: This is a retrospective review of medical records of all paediatric patients presenting to hospitals in Fiji over a 5-year period (2006-2010) with a diagnosis of osteomyelitis. Data were collected from the three divisional hospitals in Fiji (Colonial War Memorial Hospital, Lautoka Hospital and Labasa Hospital). RESULTS: Two hundred and twenty patients were identified. An annual incidence of 18.1 cases/100,000 paediatric population was identified. The highest incidence was in the itaukei (ethnic Fijian) population (21 cases/100,000). Males were at a higher risk of developing osteomyelitis (20.8/105 vs. 10.7/105). Staphylococcus Aureus was identified in 86% of all positive blood and 81% of all positive pus cultures, and it was sensitive to cloxacillin in 100% of cases. The most common factor identified preceding the development of osteomyelitis was trauma (55%) followed by skin sepsis (32%). Fifty-four per cent of the cases had chronic osteomyelitis, and the most common mode of presentation was in the form of an abscess (48%) followed by sinus/sequestrum (24%). The age group most commonly affected was between 5 and 9 years of age (19.6/105). Children with chronic osteomyelitis were more likely to require operative intervention in addition to antibiotics as compared to acute osteomyelitis (85 vs. 24%). The success rate of treating acute osteomyelitis was 92% compared to 61% for chronic osteomyelitis. CONCLUSION: Paediatric osteomyelitis poses a significant problem in Fiji, especially in the male, ethnic Fijian population between 5 and 9 years of age. The chance of complete resolution after treatment of acute osteomyelitis is very good. Therefore, interventions aimed at early diagnosis and treatments are required.

Intravenous Local Anaesthetic Compared with Intraperitoneal Local Anaesthetic in Abdominal Surgery: A Systematic Review.

INTRODUCTION: Modern perioperative care strategies aim to optimise perioperative care by reducing the body's stress response to surgery. A major facet of optimising an abdominal surgery analgesia programme is using a multimodal opioid sparing approach. Local anaesthetics have shown promise and there has been considerable research into the most effective route for their administration. This review aims to determine if there is a difference in analgesic efficacy between intraperitoneal local anaesthetic (IPLA) and intravenous local anaesthetic (IVLA). MATERIALS AND METHODOLOGY: In concordance with the PRISMA statement, a literature search was conducted to identify randomised control trials that compared IVLA with IPLA in abdominal surgery. The primary outcomes of interest were opioid analgesia requirements and pain score assessed by visual analogue score. Data were extracted and entered into pre-designed electronic spreadsheets. RESULTS: This review has identified six papers that compared intravenous lignocaine to intraperitoneal lignocaine. This review showed significantly lower morphine consumption at 4 and 24 h in the intraperitoneal group. There was no significant difference in pain scores. CONCLUSION: From the analysis of these studies, intraperitoneal local anaesthetic had an analgesic benefit over intravenous lignocaine with regard to decreased opioid consumption for abdominal surgery. Further research investigating IVL combined with intraperitoneal local anaesthetic is warranted.

Intravenous lignocaine in colorectal surgery: a systematic review.

BACKGROUND: Colorectal surgery leads to morbidity during recovery including pain and fatigue. Intravenous (IV) lignocaine (IVL) has both analgesic and anti-inflammatory effects that may improve post-operative pain and recovery. The aim of this review is to compare the effectiveness of IVL to other perioperative analgesia regimens for reducing pain and opioid consumption following colorectal surgery. METHODS: Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, a literature search was conducted to identify randomized clinical trials that compared IVL with IV placebo or epidural anaesthesia in open or laparoscopic colorectal surgery. The primary outcomes were opioid requirements and pain scores assessed by visual analogue score. Data were entered into pre-designed electronic spreadsheets. RESULTS: The literature search identified 2707 studies. A total of nine randomized clinical trials met the inclusion criteria. Five studies investigated IVL compared with IV placebo and four studies investigated IVL compared with epidural anaesthesia. Two out of the five studies comparing IVL and placebo showed statistically significant reductions in opioid consumption with IVL. There was a variable degree of improvement in pain scores when IVL was compared with epidural. Two studies showed a significant difference, with lower opioid consumption and pain scores in the epidural group. Laparoscopic and open procedures could not be compared between the IVL and placebo group. CONCLUSION: IVL has shown limited benefit towards reducing early pain and morphine consumption when compared with placebo in colorectal surgery. However, IVL did not show any significant reduction in pain or opioid consumption when compared with epidural. Further research investigating IVL combined with intraperitoneal local anaesthetic is warranted.

Individualised follow-up booklets improve recall and satisfaction for cancer patients.

AIMS: The New Zealand Provisional Standards of Service Provision for Cancer recommend providing patients with written information about their diagnosis, treatment and follow up. This project aimed to develop and evaluate a resource that could be used to provide essential information to patients who were nearing completion of the surgical treatment of their cancer. METHODS: The study compared patients with melanoma, colorectal and breast cancers who received standard discussion of their diagnosis, treatment and follow-up plan with cancer patients who received a discussion supported by an individualised follow-up booklet. Patients were interviewed using an over-the-phone questionnaire to assess their free recall and prompted recall of follow-up items, their perception of the level of information received and satisfaction with the communication of their follow-up plan. RESULTS: The group who received a booklet as part of discussion of their follow-up plan scored significantly higher on measures of free recall, prompted recall, satisfaction with the level of information provided and overall satisfaction than those who had a standard clinic discussion but did not receive a booklet. Free recall of two relevant items improved from 61% of patients to 91%. Prompted recall of at least one item improved from 77% of patients to 100%. The proportion of patients feeling they did not receive enough information fell from 25% to 5%. The proportion of patients scoring their satisfaction at >8/10 increased from 68% to 87%. All of these measures reached significance. CONCLUSION: Individualised cancer follow-up booklets are a simple, low-cost and low-risk initiative that used in a New Zealand setting, was associated with improved patient recall and satisfaction with the follow-up information they received. This supports the benefit of providing participants with personalised written information, as recommended in the New Zealand Provisional Standards of Service Provision for Cancer.

Clinical Prediction Rules for Appendicitis in Adults: Which Is Best?

BACKGROUND: Clinical prediction rules (CPRs) provide an objective method of assessment in the diagnosis of acute appendicitis. There are a number of available CPRs for the diagnosis of appendicitis, but it is unknown which performs best. AIM: The aim of this study was to identify what CPRs are available and how they perform when diagnosing appendicitis in adults. METHOD: A systematic review was performed in accordance with the PRISMA guidelines. Studies that derived or validated a CPR were included. Their performance was assessed on sensitivity, specificity and area under curve (AUC) values. RESULTS: Thirty-four articles were included in this review. Of these 12 derived a CPR and 22 validated these CPRs. A narrative analysis was performed as meta-analysis was precluded due to study heterogeneity and quality of included studies. The results from validation studies showed that the overall best performer in terms of sensitivity (92%), specificity (63%) and AUC values (0.84-0.97) was the AIR score but only a limited number of studies investigated at this score. Although the Alvarado and Modified Alvarado scores were the most commonly validated, results from these studies were variable. The Alvarado score outperformed the modified Alvarado score in terms of sensitivity, specificity and AUC values. CONCLUSION: There are 12 CPRs available for diagnosis of appendicitis in adults. The AIR score appeared to be the best performer and most pragmatic CPR.
