The provision of general surgery in rural Australia: a narrative review.

Rural surgery is most commonly provided by general surgeons to the 29% of people (7 million) living in rural Australia. The provision of rural general surgery to enable equitable and safe surgical care for rural Australians is a multifaceted issue concerning recruitment, training, retention, surgical procedures and surgical outcomes. Sustaining the rural general surgical workforce will be dependent upon growing an increased number of resident rural general surgeons, as well as changed models of care, with a need for ongoing review to track the outcomes of these changes. To increase recruitment, rural general surgical training must improve to be less stressful for trainees and to be incorporated alongside a rural-facing generalist curriculum. Rural general surgical outcomes (excluding some oncology conditions) achieve comparable results to metropolitan centres. Access to, and outcomes of, surgical oncology services continues to be inequitable for rural Australians and should be a major focus for improved service delivery.

Rural general surgeon confidence with managing vascular emergencies: A national survey.

OBJECTIVE(S): Life and limb threatening vascular emergencies often present to rural hospitals where only general surgery services are available. It is known that Australian rural general surgical centres encounter 10-20 emergency vascular surgery procedures annually. This study aimed to assess rural general surgeons' confidence managing emergent vascular procedures. SETTING, PARTICIPANTS AND DESIGN: A survey was distributed to Australian rural general surgeons to determine their confidence (Yes/No) in performing emergent vascular procedures including limb revascularisation, revising arterio-venous (AV) fistulas, open repair of ruptured abdominal aortic aneurysm (AAA), superior mesenteric artery (SMA)/coeliac embolectomy, limb embolectomy, vascular access catheter insertion and limb amputation (digit, forefoot, below knee and above knee). Confidence level was compared with surgeon demographics and training. Variables were compared using univariate logistic regression. RESULTS: Sixteen per cent (67/410) of all Australian rural general surgeons responded to the survey. Increased age, years since fellowship and training prior to 1995 (when separation of Australian vascular and general surgery occurred) were associated with greater confidence in limb revascularisation, revising AV fistulas, open repair of ruptured AAA, SMA/coeliac embolectomy, and limb embolectomy (p < 0.05). Surgeons who completed >6 months of vascular surgery training were more comfortable with SMA/coeliac embolectomy (49% vs. 17%, p = 0.01) and limb embolectomy (59% vs. 28%, p = 0.02). Confidence in performing limb amputation was similar across surgeon demographics and training (p > 0.05). CONCLUSION: Recently graduated rural general surgeons do not feel confident in managing vascular emergencies. Additional vascular surgery training should be considered as part of general surgical training and rural general surgical fellowships.

Creating a sustainable rural general surgery workforce: what enables fellows to return as rural general surgeons?

INTRODUCTION: In the context of shortfalls in rural general surgeon supply, this research aims to explore why rural general surgical Fellows returned and remained after fellowship at a single rural centre in Victoria, Australia. Fellowship positions post achievement of Fellowship of the Australasian College of Surgeons are traditionally not funded by government because they currently fall outside the accredited rural training post funding provided by the federal government. This article aims to explore if fellowship positions can be an important part in sustaining the rural general surgery workforce. METHODS: Semi-structured interviews were conducted with nine former general surgery Fellows from a single rural Australian institution. Interviews were recorded, transcribed, coded and themed to undertake analysis according to thematic analysis. RESULTS: This research demonstrates that consultant rural general surgeons can be recruited from a fellowship year when emphasis is placed on: (1) creating a positive workplace culture with safe working hours, (2) ensuring diversification of the general surgical case mix, (3) facilitating opportunities for schooling and work for the surgeon's family, and (4) preferentially selecting for those who identify as rural general surgeons. Rural towns can effectively recruit general surgeons when families are supported with career and school opportunities, and the newly qualified surgeon can initially commit to a 12-month position so that opportunities can be assessed by the entire family unit. Fellowship positions (post completion of general surgical training) allow young surgeons to 'try before they buy' prior to moving to a rural area. CONCLUSION: Ensuring a sustainable general surgical workforce in a rural community requires employee and surgical leadership to ensure a collaborative and progressive culture, which offers work diversity, supports the family lifestyle and petitions for selecting those who embody the rural general surgeon identity. Post-fellowship positions can enable young general surgeons to have exposure to the realities of a rural lifestyle, which is likely to have a positive effect on recruitment. Due to the return investment of the fellowship program, we propose that the federal government should look at funding post-fellowship positions to improve rural recruitment.

Diagnosing with a TWIST: Systematic Review and Meta-Analysis of a Testicular Torsion Risk Score.

PURPOSE: The Testicular Workup for Ischemia and Suspected Torsion (TWIST) score is a 7-point tool to evaluate acute scrotal pain. Parameters include testicular swelling (2 points), hard testis (2), high-riding testis (1), absent cremasteric reflex (1) and nausea/vomiting (1). This review aimed to determine the diagnostic utility of TWIST and its role in risk stratification. MATERIALS AND METHODS: A systematic review and meta-analysis of diagnostic test accuracy was conducted. Five risk stratification systems were explored, including the Barbosa (0-2, 3-4, 5-7) and Sheth (0, 1-5, 6-7) scoring systems, to obtain sensitivity, specificity and area under the receiver operating curve. RESULTS: Thirteen studies were identified, 9 prospective studies proceeded to meta-analysis of diagnostic test accuracy and 5 pediatric studies (1,060 patients, 199 torsions) were included in the primary analysis. The most accurate risk stratification system was Barbosa (0-2, 3-4, 5-7), with an AUC of 0.924 (95% CI: 0.865, 0.956). Barbosa showed favorable sensitivity in low-risk patients (0.984), facilitating rule out of torsion, and favorable specificity (0.975) in high-risk patients, facilitating urgent surgical exploration. Sensitivity and specificity in intermediate-risk patients were 0.922 and 0.682, respectively, indicating a need for further workup with ultrasound. Using this stratification, 65.2% of patients were low-risk, 19.9% were intermediate-risk and 14.9% were high-risk. Per 100 presentations of acute scrotum, there was a missed torsion rate of 1.6/100, ultrasound rate of 19.9/100 and negative exploration rate of 2.5/100. CONCLUSIONS: TWIST is an effective tool for suspected testicular torsion and is appropriate for widespread adoption. The Barbosa scoring system is reliable and reduces reliance on scrotal ultrasound.

Open versus Endovascular Abdominal Aortic Aneurysm Repair in the Australian Private Sector Over Twenty Years.

PURPOSE: Over the past two decades, the proliferation of endovascular surgery has changed the approach to abdominal aortic aneurysm (AAA) repair. In Australia, close to two-thirds of surgical procedures are performed in the private healthcare system. We aimed to describe the trends in AAA repair in the Australian private sector throughout the early 21st century. MATERIALS AND METHODS: Medicare Benefits Schedule (MBS) statistics were accessed to determine the number of infrarenal open AAA repair (OAR) and endovascular AAA repair (EVAR) procedures performed between January 2000 and December 2019. Population data were extracted from the Australian Bureau of Statistics and used to calculate incidence per 100,000 population. Further analysis was performed according to age, gender, and state. RESULTS: During the study period, 13,193 (67.0%) EVARs and 6504 (33.0%) OARs were performed in the Australian private sector. OARs fell from 70.5% (n=567) of AAA repairs in 2000 to 15.7% (n=237) in 2019, while EVARs rose from 29.5% (n=151) to 84.3% (n=808). The frequency of EVAR surpassed OAR in 2004. The overall incidence of AAA repair varied minimally over the time period (range: 4.9-6.5 per 100,000 adults per year). AAA repair was more common in males than females (9.7 vs 1.7 per 100,000 population) and more common in older age groups. There was a 4-fold increase in EVAR among males older than 85 years (12.8-57.4 per 100,000 population), the largest rise of any group. The overall EVAR:OAR ratio increased from 0.4 to 5.4. There were considerable state-based discrepancies. CONCLUSION: The landscape of AAA repair in Australian private sector has drastically changed with a clear preference toward EVAR. EVAR saw increased use across all genders, age groups and states, despite stable rates of AAA surgery. Further research is necessary to compare our findings to national trends in the Australian public sector.

Vasovasostomy: A systematic review and meta-analysis comparing macroscopic, microsurgical, and robot-assisted microsurgical techniques.

BACKGROUND AND OBJECTIVES: Vasovasostomy is a cost-effective procedure for the reversal of vasectomy. A water-tight adequately blood-supplied mucosal anastomosis is required for better outcomes. This review aimed to compare the outcome of vasovasostomy performed by three different techniques: macroscopic, pure microsurgical, and robot-assisted microsurgical techniques. METHODS: Scopus, Web of Science, PubMed, Embase, and Cochrane library databases were searched for relevant studies from January 1901 to June 2023. We conducted our quantitative syntheses using the inverse variance method in OpenMeta software. The study's protocol was registered on PROSPERO. RESULTS: This review involved 95 studies of different designs, with a total sample size of 48,132. The majority of operations were performed bilaterally, and participants were monitored for up to 10 years. The pooled patency rate was the highest following robot-assisted vasovasostomy (94.4%), followed by pure microsurgical vasovasostomy (87.5%), and macroscopic vasovasostomy (83.7%). The pooled pregnancy rate following purely microsurgical vasovasostomy was higher than that of macroscopic vasovasostomy (47.4 vs. 43.7%). Definitive pregnancy rates in robotic vasovasostomy are yet to be determined. CONCLUSION: Patency outcomes for vasovasostomy were best with robot-assisted microsurgical technique, followed by pure microsurgical technique, and conventional macroscopic technique. Further investigations of robot-assisted microsurgical vasovasostomy outcomes and randomized control trials are required to support this evidence.

Pre-rehabilitation interventions for patients with head and neck cancers: A systematic review and meta-analysis.

OBJECTIVE: To investigate the effect of pre-rehabilitation interventions such as nutrition and exercise for patients with head and neck cancer (HNC). METHODS: Web of Science, PubMed, Scopus, Google Scholar, and Cochrane databases were searched up to December 2022. Quality of life, length of hospital stay, postoperative complications, change in body mass index or muscle mass, and functional assessments were the primary outcomes. PRISMA guidelines were adhered to, and the study was registered on PROSPERO. The Cochrane Collaboration tool and Newcastle Ottawa scale assessed the quality of included studies. Pooled data are presented as odds ratios (OR) and 95% confidence intervals (CI). Analysis was conducted using RevMan5.4. RESULTS: A total of 31 articles were included for quantitative analysis and 15 for qualitative synthesis. Nutrition alone resulted in significant weight retention (2.60; 2.32, 2.88, p < 0.00001), length of stay (-4.00; -6.87, -1.13), p = 0.0006) and complications (0.64; 0.49, 0.83, p = 0.0009). Nutrition and psychoeducation resulted in a significant reduction in mortality rate (0.70; 0.49, 1.00, p = 0.05 and 0.60; 0.48, 0.74, p < 0.00001), and exercise resulted in a significant reduction in dysphagia (0.55; 0.35, 0.87, p = 0.01). Exercise with nutrition resulted in significant improvements in weight loss, length of stay, complications, and dysphagia. Randomized controlled trials (RCTs) had a moderate risk of bias and cohort studies were of fair to good quality. CONCLUSION: Prehabilitation programs based on exercise, nutrition, or psychoeducation demonstrated improved post-interventional outcomes in HNC, such as quality of life, and mortality and morbidity. Studies with longer follow-ups and larger sample sizes, and investigations comparing nutritional supplements with exercise programs are needed.

Prevalence of Renal Neoplasia in Autosomal Dominant Polycystic Kidney Disease: Systematic Review and Meta-Analysis.

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited condition; however, its relationship with renal cell carcinoma (RCC) remains unclear. This paper aims to establish the prevalence of RCC and its subtypes amongst ADPKD patients. METHODS: A database search was conducted to retrieve studies reporting RCC occurrence within ADPKD patients until July 2023. Key outcomes included number and subtype of RCC cases, and number of RCCs presenting incidentally. A random-effects meta-analysis was performed. RESULTS: Our search yielded 569 articles, 16 met the inclusion criteria. Nephrectomy specimens from 1,147 ADPKD patients were identified. Of studies reporting per-kidney results (n = 13), 73 RCCs were detected amongst 1,493 kidneys, equating to a per-kidney prevalence of 4.3% (95% CI, 3.1-5.7, I2 = 15.7%). 75 ADPKD patients were found to have RCC (75/1,147), resulting in a per-person prevalence of 5.7% (95% CI, 3.7-7.9, I2 = 40.3%) (n = 16). As 7 patients had bilateral disease, 82 RCCs were detected in total. Of these, 39 were clear cell RCC, 35 were papillary and 8 were other. As such, papillary RCCs made up 41.1% (95% CI, 25.9-56.9, I2 = 18.1%) of detected cancers. The majority of RCCs were detected incidentally (72.5% [95% CI, 43.7-95.1, I2 = 66.9%]). CONCLUSION: ADPKD appears to be associated with the papillary RCC subtype. The clinical implications of these findings are unclear, however, may become apparent as outcomes and life expectancy amongst APDKD patients improve.

Fournier gangrene with concurrent multifocal necrotizing fasciitis: a systematic review and case report.

PURPOSE: A patient presented to a regional surgical center with Fournier gangrene (FG) and concurrent multifocal necrotizing fasciitis (NF). Given the rarity, it was decided to undertake a systematic review to investigate the incidence and prevalence of FG with multifocal NF and consequently determine the treatment and approach to management of such presentation. METHODS: Firstly, the report of the 56-year-old male patient is discussed regarding his surgical management. Secondly, a systematic review was undertaken according to PRISMA guidelines using MEDLINE, Scopus, and Embase databases. Searches used the following MeSH terms: ("fournier's gangrene") AND ((necrotising fasciitis) OR (necrotising soft tissue infection)). Once the search results were obtained, duplicate articles were removed. Titles, abstracts, and articles were reviewed by 2 authors. RESULTS: The search strategy using the 3 databases revealed a total of 402 studies. Fifty-seven studies were removed due to duplication. A total of 345 records were screened via title and abstract, of which 115 were excluded. Two hundred and thirty studies were reviewed for eligibility. A total of all 230 studies were excluded; 169 were excluded as they included the incorrect patient population (patients suffered from FG or NF, but not both collectively), 60 studies were excluded due to incorrect study designs, and 1 report occurred in the wrong setting. CONCLUSION: This highlights that while being a relatively known, uncommon infection both FG and NF are well documented separately within the literature. However, FG with concurrent multifocal NF has not been documented within the literature.

Colorectal surgical management of colitis induced by vasculitis in the absence of inflammatory bowel disease: a case report and literature review.

Colitis caused by vasculitis is a rare and poorly understood pathology. Little evidence exists on its clinical presentation, path to diagnosis, and surgical management. In this report, we present a case report and literature review. A healthy 20-year-old male patient presented with hemorrhagic colitis requiring total colectomy with end ileostomy. Pathological examination showed pancolitis with multiple ulcers, transmural inflammation, hemorrhage, and microvascular thrombosis. Extensive serological testing revealed elevated cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and eosinophilia, leading to a diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) and vasculitis-induced colitis. A literature review was subsequently conducted. Nineteen studies were found documenting vasculitis-induced colitis in the absence of inflammatory bowel disease (IBD). Systemic signs of vasculitis, hemorrhagic colitis, and progression to fulminant colitis were present. Of all patients, 40.0% required colorectal surgery and 62.5% of those patients received a stoma; 25% underwent emergency surgery following failed immunosuppression. All cases relied on clinical correlation with serology and/or histopathology to reach a final diagnosis. We report a case of vasculitis-induced colitis caused by c-ANCA-positive EGPA. The review shows that vasculitis-induced colitis without IBD is an important differential that clinicians should be aware of in patients presenting with colitis.

Local anaesthetic infiltration in rubber band ligation of rectal haemorrhoids: study protocol for a three-arm, double-blind randomised controlled trial (PLATIPUS trial).

INTRODUCTION: Rubber band ligation ('banding') is a common approach for the management of symptomatic haemorrhoids. However, up to 90% of patients experience postprocedural pain, and there is no consensus regarding the optimal analgesic strategy. In practice, patients may receive submucosal local anaesthetic, pudendal nerve block or routine periprocedural analgesia. The aim of this study is to compare the efficacy of submucosal local anaesthetic, pudendal nerve block and routine analgesia for postprocedural pain in patients undergoing haemorrhoid banding. METHODS AND ANALYSIS: This is a multicentre, prospective, three-arm, double-blind randomised controlled trial of adults booked for haemorrhoid banding. Participants will be randomised to one of three groups in a 1:1:1 ratio: (1)submucosal bupivacaine injection; (2) pudendal nerve ropivacaine injection and (3) no local anaesthetic. The primary outcome is patient reported postprocedural pain (scored 0-10) from 30 min to 2 weeks. Secondary outcomes include postprocedural analgesia use, time to discharge, patient satisfaction, time to return to work and complications. A sample size of 120 patients is required to achieve statistical significance. ETHICS AND DISSEMINATION: This study received Human Research Ethics Approval from the Austin Health Human Research Ethics Committee (March 2022). Trial results will be submitted to a peer-reviewed journal, and presented at academic meetings. A summary of the trial results will be made available to study participants on request. TRIAL REGISTRATION NUMBER: ACTRN12622000006741p.

Epidemiological trends of gallbladder cancer in Australia between 1982 to 2018: A population-based study utilizing the Australian Cancer Database.

Backgrounds/Aims: Gallbladder cancer (GBC) is a rare neoplasm. The epidemiology of GBC has not been updated in Australia for over five decades. Methods: Data of all Australian patients diagnosed with GBC at any age from 1982 to 2018 were identified from the Australian Cancer Database. Age-standardized rates were calculated and joinpoint analysis was performed to ascertain the trends of incidence and mortality of GBC. Results: Between 1982 and 2018, there were 22,745 cases of GBC and 11,054 GBC-related deaths in Australia. There were three distinct periods showing changed incidence. Period 1 (1982-1995) was stable. Period 2 (1996-2006) showed reduced incidence in females (3.6 to 2.8/100,000; p < 0.01) and all Australians (3.7 to 2.8/100,000, p < 0.01). Period 3 (2006-2017) demonstrated significantly increased incidence in all groups (males: 2.7 to 4.0/100,000, p < 0.01; females: 2.8 to 3.5/100,000, p < 0.01; all Australians: 2.8 to 3.7/100,000, p < 0.01). Incidence between females and males had declined from 1.10 : 1 in 1982 to 0.87 : 1 in 2017. There was a 71% reduction in mortality (3.1 to 0.9/100,000; p < 0.01). Median age at diagnosis increased from 69.7 to 74.3 years for females and from 67.2 to 73.3 years for males. Increasing incidence in the 6th to 8th decade of life in males, compared to previous years, was noted. Conclusions: Incidence, mortality, sex, and age of GBC have significantly changed in Australia since 1982. Rising incidence of GBC in Australia warrants further investigation.

Gallbladder-associated hospital admission and cholecystectomy rates across Australia and Aotearoa New Zealand (2004-2019): Are we over-intervening?

Backgrounds/Aims: To investigate if the increase in the number of cholecystectomies is proportional to symptomatic gallbladder-associated hospital admissions in Australia and Aotearoa New Zealand (NZ). Methods: National healthcare registries were used to obtain data on all episodes of cholecystectomies and hospital admissions for patients ≥ 15 years from public and private hospitals. Results: Between 2004 and 2019, in Australia, there have been 1,074,747 hospital admissions and 779,917 cholecystectomies, 715,462 (91.7%) of which were laparoscopic, and 163,084 admissions and 98,294 cholecystectomies in NZ. The 15-54 years age group saw an increase in operative rates, +4.0% in Australia and +6.6% in NZ, and admissions, +3.7% and +5.8%, respectively. Hospital admissions decreased by -9.8% in Australia but the proportion of patients undergoing intervention increased by 10.8% (from 67.1% to 75.0% of hospital admissions). Procedural rates increased by +7.3% in NZ with no change in the intervention rate. Conclusions: In Australia, there has been a decline in symptomatic gallbladder-associated hospital admissions and a rise in intervention rate. Admissions and interventions have increased proportionally in NZ. There are higher rates of cholecystectomy and admission amongst younger demographics, compared to historical cohorts. Future research should focus on identifying risk factors for increased disease and operative rates amongst younger populations.

Misleading medical literature: An observational study.

OBJECTIVE: Language that implies a conclusion not supported by the evidence is common in the medical literature. The hypothesis of the present study was that medical journal publications are more likely to use misleading language for the interpretation of a demonstrated null (i.e. chance or not statistically significant) effect than a demonstrated real (i.e. statistically significant) effect. METHODS: This was an observational study of the medical literature with a systematic sampling method. Articles published in The Journal of the American Medical Association, The Lancet and The New England Journal of Medicine over the last two decades were eligible. The language used around the P-value was assessed for misleadingness (i.e. either suggesting an effect existed when a real effect did not exist or vice versa). RESULTS: There were 228 unique manuscripts examined, containing 400 statements interpreting a P-value proximate to 0.05. The P-value was between 0.036 and 0.050 for 303 (75.8%) statements and between 0.050 and 0.064 for 97 (24.3%) statements. Forty-four (11%) of the statements were misleading. There were 40 (41.2%) false-positive sentences, implying statistical significance when the P-value was >0.05, and four (1.3%) false-negative sentences, implying no statistical significance when the P-value <0.05 (relative risk 31.2; 95% confidence interval 11.5-85.1; P < 0.0001). The proportion of included manuscripts containing at least one misleading sentence was 16.2% (95% confidence interval 12.0-21.6). CONCLUSIONS: Among a random selection of sentences in prestigious journals describing P-values close to 0.05, 1 in 10 are misleading (n = 44, 11%) and this is more prevalent when the P-values are above 0.05 compared to below 0.05. Caution is advised for researchers, clinicians and editors to align with the context and purpose of P-values.

Ureteric orifice obstruction by catheter balloon Post-TURP: A rare cause of obstructive uropathy.

A 50-year-old male underwent small volume TURP for median lobe prostatic hypertrophy. Post-procedure, a 3-way urethral catheter was placed. He subsequently developed flank pain, anuria and creatinine rise. CT demonstrated bilateral obstructive uropathy. In the absence of obstructing lesions, it was suspected that the catheter balloon may have caused obstruction of bilateral ureteric orifices. Balloon deflation (from 30 to 10 mL) and catheter repositioning resulted in rapid resolution of pain and resumption of urine output. Urologists should consider the catheter balloon as a cause of obstructive uropathy, especially after procedures where normal trigonal anatomy is disrupted.

Long peripheral catheters and midline catheters: Insights from a survey of vascular access specialists.

BACKGROUND: Peripheral intravenous access is no longer limited to the standard intravenous catheter (cannula). Devices varying in length, material and insertion technique, are increasingly accessible. There is substantial variability surrounding the nomenclature and use of these devices in the literature. We wished to understand the attitude of vascular access specialists towards the nomenclature and use of peripheral intravenous catheters (PIVCs), long peripheral catheters (LPCs) and midline catheters (MCs). METHODS: A 15-question electronic survey was sent to members of the Association of Vascular Access (AVA) regarding the nomenclature and use of PIVCs, LPCs and MCs. RESULTS: A total of 228 participants completed the survey. Approximately two-thirds of respondents use LPCs (65.8%) and MCs (71.9%) in their clinical practice. The most common indication for LPCs was difficult venous access (56.5%), while the most common indication for MCs was medium-term (1-4 weeks) intravenous therapy (62.7%). The majority of participants (57.9%) agreed with the following classification of peripheral intravenous devices:PIVCs: 2 to 6 cm in length, terminating distal to the axilla;LPCs: 6 to 15 cm in length, terminating distal to the axilla;MCs: 15-25 cm in length, terminating in the axilla.Participants suggested that the length of the catheter should be considered a general recommendation, as LPCs and MCs should be primarily differentiated by tip location. CONCLUSIONS: The majority of vascular access specialists from AVA have incorporated LPCs and MCs into their repertoire of peripheral venous access tools. We envisage that their use will increase as the clinical community becomes more familiar with these devices.

Standard Versus Long Peripheral Catheters for Multiday IV Therapy: A Randomized Controlled Trial.

OBJECTIVES: In children, intravenous therapy (IVT) is generally administered via peripheral intravenous catheters (PIVCs) (2-6 cm in length). There is evidence that PIVCs are unreliable after 2 days. Long peripheral catheters (LPCs) (6-15 cm in length) could improve the delivery of IVT. The aim of this trial was to determine if LPCs could decrease catheter failure and the number of catheters in children receiving multiday IVT. METHODS: This was an open-label randomized controlled trial conducted at Monash Children's Hospital in Melbourne, Australia. Participants were from the ages of 1 to 17 years, undergoing surgery and requiring >48 hours of postoperative IVT. Participants were randomly assigned to a 2.5-cm 22G PIVC or an 8-cm 22G LPC. RESULTS: Seventy-two children were randomly assigned, 36 received PIVCs, and 36 received LPCs. The median duration of IVT was 5.1 days and was similar between groups (P = .9). Catheter failure was higher for PIVCs than LPCs (66.7% vs 19.4%; relative risk [RR]: 3.4; P = .0001 or 187.9 vs 41.0 failures per 1000 catheter-days). Infiltration was the most common reason for PIVC failure (33.3% vs 2.8%; RR: 12.0; P = .001). LPCs exhibited superior life span (4.7 vs 3.5 days [median]; P = .01). Children with LPCs were twice as likely to complete therapy with a single catheter (80.6% vs 38.9%; RR: 2.1; P = .0006). CONCLUSIONS: LPCs reduce catheter failure and total catheters in children. They should be considered as the first-line device for peripheral access in any child receiving prolonged IVT.

Long peripheral catheters for intravenous access in adults and children: A systematic review of the literature.

BACKGROUND: Long peripheral catheters are peripheral intravenous catheters of 6-15 cm in length. They are commonly inserted into the forearm, antecubital fossa or upper arm using a direct Seldinger technique. They have proven to be valuable for peripheral intravenous catheters, particularly in patients with difficult intravenous access. METHODS: We conducted a systematic review of studies reporting the use of long peripheral catheters. The following keywords were used: 'long', 'Seldinger', 'guidewire', 'peripheral', 'venous', 'intravenous', 'IV', 'vascular', 'cannula' and 'catheter'. RESULTS: Three hundred forty-one publications were identified; 16 were included in the systematic review. There were 11 adult studies and 5 paediatric studies documenting 1288 long peripheral catheters in 1271 patients. Majority of studies (12/16) were conducted in acute care settings, (emergency department, n = 6; intensive care unit, n = 3; high dependency unit, n = 1; surgical unit, n = 2). The most frequently studied long peripheral catheter was 8 cm in length and 20 G in size. Nine studies recruited patients with difficult intravenous access; 11 studies used ultrasound guidance. Insertion success rate and mean procedural time ranged between 86% and 100% and 8 and 16.8 minutes, respectively. Average catheter duration ranged between 4 and 14.7 days (mean) and 1.1 and 9 days (median). Catheter failure occurred in 4.3-52.5% of long peripheral catheters, with leakage, infiltration and dislodgement being the most frequent causes of failure. In 3 randomised controlled trials, long peripheral catheters outperformed peripheral intravenous catheters in terms of duration and failure rate. CONCLUSION: Long peripheral catheters are safe and reliable in both adults and children. In addition, long peripheral catheters may provide improved quality of care over peripheral intravenous catheters for multi-day intravenous therapy.
