Provision of immediate postpartum intrauterine contraception after vaginal birth within a public maternity setting: Health services research evaluation.

INTRODUCTION: Expanding access to postpartum intrauterine contraception (PPIUC) can reduce unintended pregnancies and short inter-pregnancy intervals; however, provision across Europe is limited. Our aim was to determine the feasibility, clinical outcomes and patient satisfaction of providing immediate PPIUC after vaginal birth using a health services research model. MATERIAL AND METHODS: Phased introduction of PPIUC across two Lothian maternity hospitals; all women intending vaginal birth during the study period without a contraindication to use of the method were eligible to receive PPIUC. Midwives and obstetric doctors were trained in vaginal PPIUC insertion using Kelly forceps. Women received information antenatally and had PPIUC insertion of either a levonorgestrel intrauterine system or a copper intrauterine device within 48 hours of vaginal birth. Follow-up was conducted in-person at 6 weeks postpartum and by telephone at 3, 6 and 12 months. Primary outcomes were: uptake, complications (infection, uterine perforation), expulsion and patient satisfaction at 6 weeks; and method of continuation up to 12 months. Secondary outcomes included hazard ratio for expulsion adjusted for demographic and insertion-related variables. RESULTS: Uptake of PPIUC was 4.6% of all vaginal births; 465/447 (96.1%) of those requesting PPIUC successfully received it and most chose a levonorgestrel intrauterine system (73%). At 6 weeks postpartum, the infection rate was 0.8%, there were no perforations and 98.3% of women said they would recommend the service. The complete expulsion rate was 29.8% (n = 113) and most had symptoms (n = 79). Of the additional 121 devices removed, 118 were because of partial expulsion. The rate of complete/partial expulsion was higher for insertions by midwives compared with those by doctors. The re-insertion rate after expulsion/removal was 87.6% and method continuation at 12 months was 79.6%. CONCLUSIONS: Routine PPIUC at vaginal birth is feasible. Complications were extremely rare. High expulsion rates may be observed in early stages of service introduction and with inexperienced providers. Re-insertion and therefore longer-term continuation rates of intrauterine contraception were very high. In settings with low rates of attendance for interval postpartum intrauterine contraception insertion, PPIUC could be a useful intervention to prevent unintended and closely spaced pregnancies.

Women's experiences of accessing postpartum intrauterine contraception in a public maternity setting: a qualitative service evaluation.

OBJECTIVES: The aims of the study were to explore women's experiences of an immediate postpartum intrauterine contraception (PPIUC) service recently introduced in a UK maternity setting, to identify areas for improvement and inform service provision. METHODS: Qualitative research was carried out in hospital and community maternity services in Lothian, UK. In-depth interviews were conducted with 35 women who had received PPIUC at vaginal or caesarean delivery. The interview data were analysed thematically to explore the women's experiences of PPIUC service provision. RESULTS: Women's decisions to choose PPIUC were influenced by their perception of intrauterine contraception (IUC) as a suitable and effective method and the convenience of immediate postpartum insertion. Most women were satisfied with their experience of PPIUC. Women delivering vaginally sometimes reported concerns about delays to insertion, particularly where they perceived a lack of communication from staff about when and where insertion would occur. PPIUC information was described as being difficult to absorb in the context of ante/postnatal information overload. Those receiving PPIUC at caesarean delivery sometimes expressed concerns about what post-insertion support might be available in primary care. CONCLUSION: Women typically reported satisfaction with their decision to have PPIUC. For maternity services considering introducing PPIUC, our findings reinforce the importance of anticipating and addressing implementation challenges in order to enhance women's experience of the service. These include ensuring that: clear and appropriate PPIUC information and support are provided antenatally; women are able to access PPIUC immediately after delivery; robust clinical pathways are in place to support post-insertion IUC care; and both staff and women are familiar with the clinical pathways.

The management of diverticulitis: a review of the guidelines.

Radiological evidence of inflammation, using computed tomography (CT), is needed to diagnose the first occurrence of diverticulitis. CT is also warranted when the severity of symptoms suggests that perforation or abscesses have occurred. Diverticulitis is classified as complicated or uncomplicated based on CT scan, severity of symptoms and patient history; this classification is used to direct management. Outpatient treatment is recommended in afebrile, clinically stable patients with uncomplicated diverticulitis. For patients with uncomplicated diverticulitis, antibiotics have no proven benefit in reducing the duration of the disease or preventing recurrence, and should only be used selectively. For complicated diverticulitis, non-operative management, including bowel rest and intravenous antibiotics, is indicated for small abscesses; larger abscesses of 3-5 cm should be drained percutaneously. Patients with peritonitis and sepsis should receive fluid resuscitation, rapid antibiotic administration and urgent surgery. Surgical intervention with either Hartmann procedure or primary anastomosis, with or without diverting loop ileostomy, is indicated for peritonitis or in failure of non-operative management. Colonoscopy is recommended for all patients with complicated diverticulitis 6 weeks after CT diagnosis of inflammation, and for patients with uncomplicated diverticulitis who have suspicious features on CT scan or who otherwise meet national bowel cancer screening criteria.

Isotope Dilution-Based Targeted and Nontargeted Carbonyl Neurosteroid/Steroid Profiling.

Neurosteroids are brain-derived steroids, capable of rapidly modulating neuronal excitability in a nongenomic manner. Dysregulation of their synthesis or metabolism has been implicated in many pathological conditions. Here, we describe an isotope dilution based targeted and nontargeted (ID-TNT) profiling of carbonyl neurosteroids/steroids. The method combines stable isotope dilution, hydroxylamine derivatization, high-resolution MS scanning, and data-dependent MS/MS analysis, allowing absolute quantification of pregnenolone, progesterone, 5α-dihydroprogesterone, 3α,5α-tetrahydroprogesterone, and 3ß,5α-tetrahydroprogesterone, and relative quantification of other carbonyl containing steroids. The utility and validity of this approach was tested in an acute stress mouse model and via pharmacological manipulation of the steroid metabolic pathway with finasteride. We report that brain levels of 3α,5α-tetrahydroprogesterone, a potent enhancer of GABAA receptor (GABAAR-mediated inhibitory function, from control mice is in the 5-40 pmol/g range, a value greater than previously reported. The approach allows the use of data from targeted analysis to guide the normalization strategy for nontargeted data. Furthermore, novel findings, including a striking increase of brain pregnenolone following finasteride administration were discovered in this study. Collectively, our results indicate that this approach has distinct advantages for examining targeted and nontargeted neurosteroid/steroid pathways in animal models and could facilitate a better understanding of the physiological and pathological roles of neurosteroids as modulators of brain excitability.

Dysfunctional astrocytic and synaptic regulation of hypothalamic glutamatergic transmission in a mouse model of early-life adversity: relevance to neurosteroids and programming of the stress response.

Adverse early-life experiences, such as poor maternal care, program an abnormal stress response that may involve an altered balance between excitatory and inhibitory signals. Here, we explored how early-life stress (ELS) affects excitatory and inhibitory transmission in corticotrophin-releasing factor (CRF)-expressing dorsal-medial (mpd) neurons of the neonatal mouse hypothalamus. We report that ELS associates with enhanced excitatory glutamatergic transmission that is manifested as an increased frequency of synaptic events and increased extrasynaptic conductance, with the latter associated with dysfunctional astrocytic regulation of glutamate levels. The neurosteroid 5α-pregnan-3α-ol-20-one (5α3α-THPROG) is an endogenous, positive modulator of GABAA receptors (GABAARs) that is abundant during brain development and rises rapidly during acute stress, thereby enhancing inhibition to curtail stress-induced activation of the hypothalamic-pituitary-adrenocortical axis. In control mpd neurons, 5α3α-THPROG potently suppressed neuronal discharge, but this action was greatly compromised by prior ELS exposure. This neurosteroid insensitivity did not primarily result from perturbations of GABAergic inhibition, but rather arose functionally from the increased excitatory drive onto mpd neurons. Previous reports indicated that mice (dams) lacking the GABAAR δ subunit (δ(0/0)) exhibit altered maternal behavior. Intriguingly, δ(0/0) offspring showed some hallmarks of abnormal maternal care that were further exacerbated by ELS. Moreover, in common with ELS, mpd neurons of δ(0/0) pups exhibited increased synaptic and extrasynaptic glutamatergic transmission and consequently a blunted neurosteroid suppression of neuronal firing. This study reveals that increased synaptic and tonic glutamatergic transmission may be a common maladaptation to ELS, leading to enhanced excitation of CRF-releasing neurons, and identifies neurosteroids as putative early regulators of the stress neurocircuitry.

Mutagenic analysis of the intracellular portals of the human 5-HT3A receptor.

Structural models of Cys-loop receptors based on homology with the Torpedo marmorata nicotinic acetylcholine receptor infer the existence of cytoplasmic portals within the conduction pathway framed by helical amphipathic regions (termed membrane-associated (MA) helices) of adjacent intracellular M3-M4 loops. Consistent with these models, two arginine residues (Arg(436) and Arg(440)) within the MA helix of 5-hydroxytryptamine type 3A (5-HT3A) receptors act singularly as rate-limiting determinants of single-channel conductance (γ). However, there is little conservation in primary amino acid sequences across the cytoplasmic loops of Cys-loop receptors, limiting confidence in the fidelity of this particular aspect of the 5-HT3A receptor model. We probed the majority of residues within the MA helix of the human 5-HT3A subunit using alanine- and arginine-scanning mutagenesis and the substituted cysteine accessibility method to determine their relative influences upon γ. Numerous residues, prominently those at the 435, 436, 439, and 440 positions, were found to markedly influence γ. This approach yielded a functional map of the 5-HT3A receptor portals, which agrees well with the homology model.

Contraception after abortion, miscarriage, ectopic and molar pregnancy.

Regardless of whether a pregnancy ends in abortion, miscarriage or ectopic pregnancy, fertility and sexual activity can resume quickly. For those who do not plan to become pregnant again immediately, effective contraception is therefore required. Although a contraceptive discussion and the offer to provide contraception is considered an integral part of abortion care, health care providers may not always offer this same standard of care to those whose pregnancy ends in miscarriage or ectopic due to sensitivities or assumptions around this and future fertility intentions. Yet, evidence-based recommendations support the safety of initiating contraception at these times. Provision of a chosen method of contraception may be convenient for women and valued by them. As part of holistic care, healthcare professionals who care for women around these reproductive events should therefore offer quality information on contraception and help them access their chosen method to better meet their ongoing reproductive health needs.

Scoping review protocol: exploration of the barriers and facilitators to the uptake of early postnatal contraception.

INTRODUCTION: It is well documented that many women do not desire a short interpregnancy interval. Medical societies, government agencies and leaders in the field recommend that contraception should be part of maternity care. Short spaced and unplanned pregnancies increase the chances of mortality and morbidity in the mother and child. The WHO recommends a 24-month interpregnancy interval; however, short pregnancy intervals remain common. The goal of this scoping review will be to explore barriers and facilitators to the uptake of early postnatal contraception. A review of globally published literature relating to the implementation of a postnatal contraception service provision globally will be carried out which will highlight evidence gaps, strengths and weaknesses of studies associated with uptake and known barriers and facilitators to the uptake of early postnatal contraception. METHODS AND ANALYSIS: This scoping review will be conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews. The search strategy aims to locate both published and unpublished studies. An initial limited search of PubMed and CINAHL was undertaken to identify articles on the provision of postnatal contraception. The search strategy will be adapted for each included database CINAHL, SCOPUS, MEDLINE, PROSPERO and COCHRANE from 1 January 1993 to 1 January 2023 and reviewed by two reviewers. The data will be analysed and presented in tables, diagrams and text. ETHICS AND DISSEMINATION: Ethical approval is not required. This review is a retrospective review of widely and publicly available evidence. The review findings will be disseminated via publication in peer-reviewed journals, as part of a PhD thesis and conference presentation. SCOPING REVIEW QUESTION: What are the barriers and facilitators to early postnatal contraception provision and uptake?

Time to acute general surgical review: a retrospective study in a tertiary referral centre.

BACKGROUND: The Acute Surgical Unit (ASU) is a busy service receiving Emergency Department (ED) referrals for adult and paediatric general surgery care alongside trauma. The ASU model deviates from the traditional on-call model and has been shown to improve efficiency and patient outcomes. The primary aim was to evaluate time to surgical review ED presentation and general surgical referral. Secondary aims were to assess referral numbers, pathology and demographics at our institution. METHODS: A retrospective observational analysis was conducted on all referral times from the ED to the ASU between 1 April and 30 September 2022. Patient demographics, triage and referral times, and diagnoses were collected from the electronic medical record. Time between referral, review and surgical admission were calculated. RESULTS: A total of 2044 referrals were collected during the study period, and 1951 (95.45%) were included for analysis. Average time from ED presentation to surgical referral was 4 hours and 54 min with average time to surgical review from referral taking 40 min. On average, total time from ED presentation to surgical admission was 5 h and 34 min. Trauma Responds took 6 min to review. Colorectal pathology was the most commonly referred disease type. CONCLUSION: The ASU model is efficient and effective within our health service. Overall delays in surgical care may be external to the general surgery unit, or before the patient is made known to the surgical team. Analysis of time to surgical review is a key statistic in the delivery of acute surgical care.

Laparoscopic Cholecystectomy in Pregnancy: A Seven-Year Retrospective Study From an Australian Tertiary Center.

Background Cholecystectomy is the second most common non-obstetric indication for surgery during pregnancy; however, there is little recent literature specifically exploring perioperative care approaches, and a paucity of Australian data exists. This study investigates the incidence of laparoscopic cholecystectomy (LC) during pregnancy, peri-operative management, and post-operative outcomes in a single Australian tertiary center. Methods A retrospective analysis of LCs performed on pregnant patients between the ages of 16 and 50 years at a tertiary hospital between 2016 and 2023 was completed. Results Twenty-three patients underwent LC. The median gestational age was 17+4 weeks (4+3-30+6). Cases were performed in all three trimesters, with the majority in the second trimester (n=12, 52.2%). Surgery indications were recurrent biliary colic (n=11, 47.8%), acute cholecystitis (n=8, 34.8%), and gallstone pancreatitis (n=4, 17.4%). Obstetrics and Gynecology (O&G) consultations occurred in 56.5% (n=13) of cases. Fetal heart rate (FHR) was recorded perioperatively in 82.6% (n=19) of cases. Preoperative steroids were given to 40% of eligible patients. An intraoperative cholangiogram was performed in 12 (52.2%) cases, of which eight (66.7%) utilized abdominal shielding. There was no perioperative maternal mortality nor fetal loss. Surgical morbidities were pancreatitis (n=1), bile leak (n=1), and intraoperatively recognized bile duct injury (n=1). Two threatened preterm labors and five (26.3%) preterm deliveries occurred. Conclusion Performing LC in pregnancy does carry a risk of major morbidity; however, there was no mortality or fetal loss across all trimesters. The decision to perform abdominal shielding during an intraoperative cholangiogram should be approached sensitively in a case-by-case manner, given recent paradigm shifts in radiology. A multidisciplinary approach with standardized local perioperative care policies regarding procedures such as O&G consultation, perioperative steroid use, and FHR monitoring is strongly recommended.

Rings of charge within the extracellular vestibule influence ion permeation of the 5-HT3A receptor.

The determinants of single channel conductance (γ) and ion selectivity within eukaryotic pentameric ligand-gated ion channels have traditionally been ascribed to amino acid residues within the second transmembrane domain and flanking sequences of their component subunits. However, recent evidence suggests that γ is additionally controlled by residues within the intracellular and extracellular domains. We examined the influence of two anionic residues (Asp(113) and Asp(127)) within the extracellular vestibule of a high conductance human mutant 5-hydroxytryptamine type-3A (5-HT(3)A) receptor (5-HT(3)A(QDA)) upon γ, modulation of the latter by extracellular Ca(2+), and the permeability of Ca(2+) with respect to Cs(+) (P(Ca)/P(Cs)). Mutations neutralizing (Asp → Asn), or reversing (Asp → Lys), charge at the 113 locus decreased inward γ by 46 and 58%, respectively, but outward currents were unaffected. The D127N mutation decreased inward γ by 82% and also suppressed outward currents, whereas the D127K mutation caused loss of observable single channel currents. The forgoing mutations, except for D127K, which could not be evaluated, ameliorated suppression of inwardly directed single channel currents by extracellular Ca(2+). The P(Ca)/P(Cs) of 3.8 previously reported for the 5-HT(3)A(QDA) construct was reduced to 0.13 and 0.06 by the D127N and D127K mutations, respectively, with lesser, but clearly significant, effects caused by the D113N (1.04) and D113K (0.60) substitutions. Charge selectivity between monovalent cations and anions (P(Na)/P(Cl)) was unaffected by any of the mutations examined. The data identify two key residues in the extracellular vestibule of the 5-HT(3)A receptor that markedly influence γ, P(Ca)/P(Cs), and additionally the suppression of γ by Ca(2+).

Improving Access to and Quality of Postpartum Contraception Provision.

Sexual activity and fertility can resume shortly after childbirth, but there are barriers to contraceptive access in the postpartum period. Unintended pregnancy and short interpregnancy intervals (of less than one year) can increase the risk of obstetric and neonatal complications. The antenatal period presents an opportunity to discuss contraceptive options, many of which can be safely initiated immediately after childbirth. Successful delivery of a postpartum contraception program requires an adequate number of maternity staff trained to provide the full range of methods.

A case series of bread clip ingestions.

The bread clip is one of the most insidious foreign body ingested. The bread clip poses a serious medical danger to patients yet may often fail to manifest itself clinically on initial ingestion. We present a case series of three patients with bread clips ingestions that were managed in the Gold Coast University Hospital, Queensland, Australia between 2020 and 2021. Bread clips are not always readily identifiable depending on imaging and the management of these patients will often require a multidisciplinary approach between the surgeons, gastroenterologists and radiologists.

Perspectives of obstetricians and midwives on the provision of immediate postpartum intrauterine devices: a qualitative service evaluation.

BACKGROUND: Immediate postpartum intrauterine device (PPIUD) insertion is safe and effective but largely unavailable in Europe. Data on maternity staff views on the provision and implementation of PPIUD services are limited. The objective of this qualitative evaluation was to explore the views and experiences of obstetricians and midwives providing PPIUD within a UK maternity setting, in order to identify areas for improvement and inform service provision in other areas. METHODS: Qualitative health services research within two public maternity hospitals in Lothian (Edinburgh and surrounding region), UK. Interviews with 30 maternity staff (obstetricians n=8; midwives n=22) involved in PPIUD provision. Data were analysed thematically. RESULTS: Maternity staff were positive about the benefits of PPIUD for women. Midwives reported initial concerns about PPIUD safety, and the impact on workload; these views shifted following training, and as PPIUD was embedded into practice. Having a large pool of PPIUD-trained staff was identified as an important factor in successful service implementation. Having PPIUD 'champions' was important to address staff concerns, encourage training uptake, and advocate for the service to ensure continued resourcing. CONCLUSIONS: PPIUD in maternity services can help address unmet need for effective contraception in the immediate postpartum period. We emphasise the importance of widespread engagement around PPIUD among all healthcare professionals involved in the care of women, to ensure staff are informed and supported. Clinical champions and leaders play a key role in amplifying the benefits of PPIUD, and advancing organisational learning.

An unusual case of abdominal compartment syndrome from a massive faecaloma.

Severe constipation is a frequent presentation but progression into a life-threatening acute compartment syndrome (ACS) is few and far between. This case highlights the typical physiological manifestations of ACS and the immediate benefits of correcting these physiological imbalances through the disimpaction of a massive faecaloma. Furthermore, in adult patients with a history of colonic dysmotility, adult Hirschsprung's disease should be considered.

Incidence of Clostridioides difficile in patients post loop ileostomy reversal in an Australian tertiary hospital: a retrospective study.

INTRODUCTION: The purpose of a loop ileostomy is to temporarily divert faeces away from a distal anastomosis, to reduce the consequences of anastomotic leak. This ultimately requires a second procedure to restore bowel continuity, which confers risk of complications including the development of Clostridioides difficile infection (CDI). It is hypothesized that patients who undergo loop ileostomy reversal are at increased risk of CDI when compared with other patients undergoing elective colorectal surgical procedures, and that these patients also experience an increased length of stay (LOS). METHODS: A retrospective cohort study was performed on all patients who underwent loop ileostomy reversal at the Gold Coast Hospital and Health Service between 1 January 2012 and 31 December 2019. RESULTS: Two hundred and twenty-eight patients were identified. Eight tested positive for CDI on faecal PCR (3.51%), a higher incidence than that in patients who underwent an elective colorectal surgical procedure during the same period (0.83%) (RR = 4.23). Additionally, median LOS for ileostomy reversal patients was significantly increased in those who also had CDI when compared with those without CDI (11 versus 4 days; P = 0.0003). CONCLUSION: The study confirmed that the incidence of CDI was higher in those who underwent ileostomy reversal when compared with an otherwise comparable hospital population (elective colorectal surgery patients). Additionally, those patients who underwent ileostomy reversal and had CDI experienced an increased LOS which translates to increased cost to the healthcare system. Further investigation into pre-operative screening and prophylactic antibiotics should be considered as a measure to mitigate this post-operative complication.

Influence of culture, religion and experience on the decision of Pakistani women in Lothian, Scotland to use postnatal contraception: a qualitative study.

INTRODUCTION: Evidence suggests that Pakistani women may experience difficulty accessing postnatal contraceptive (PNC) services. The study aimed to identify experience and decision-making around PNC provision for Pakistani women in Lothian, and to explore the views and experience of maternity staff who provide PNC counselling. METHODS: Qualitative research including focus groups and 1:1 semi-structured interviews with women and staff. Participants were first- and second-generation Pakistani women with a child/children aged up to 5 years, or pregnant; community and hospital midwives, obstetric doctors who counsel or provide PNC. Data were coded and categorised using QSR NVIVO10. Inductive thematic analysis was carried out. RESULTS: Women were receptive to discussion of contraception, including antenatally, and welcomed translated information. Some said the decision on PNC was theirs or made jointly with their husband; however, they acknowledged that in some marriages the husband will take the decision. Women stated they may face family expectation to have a baby early in marriage. Language was identified as a challenge by maternity staff, who utilised translation services to ensure women received the information they needed on contraception. CONCLUSIONS: Pakistani women value antenatal discussion about PNC. Maternity staff have an important role in providing quality information on contraception and should be supported with translated resources in a range of formats. Most importantly, staff should adopt a tailored approach to identify the individual woman's needs and preferences.

Novel structural determinants of single channel conductance and ion selectivity in 5-hydroxytryptamine type 3 and nicotinic acetylcholine receptors.

Nicotinic acetylcholine (nACh) and 5-hydroxytryptamine type 3 (5-HT(3)) receptors are cation-selective ion channels of the pentameric ligand-gated ion channel (pLGIC) superfamily. Multiple lines of evidence adduced over the last 30 years indicate that the lining of the channel of such receptors is formed by the alpha-helical second transmembrane (TM2) domain and flanking sequences contributed by each of the five subunits present within the receptor complex. Specific amino acid residues within, and adjacent to, the TM2 domain influence single channel conductance, ion selectivity, and other aspects of receptor function that include gating and desensitization. However, more recent work has revealed important structural determinants of single channel conductance and ion selectivity that are not associated with the TM2 domain. Direct experimental evidence indicates that the intracellular domain of eukaryotic pLGICs, in particular a region of the loop linking TM3 and TM4 termed the membrane-associated (MA) stretch, exerts a strong influence upon ion channel biophysics. Moreover, recent computational approaches, complemented by experimentation, implicate the extracellular domain as an additional important determinant of ion conduction. This brief review describes how our knowledge of ion conduction and selectivity in cation-selective pLGICs has evolved beyond TM2.

Twelve tips for OSCE-style Tele-assessment.

This article was migrated. The article was marked as recommended. The Australian College of Rural and Remote Medicine (ACRRM) has developed a flexible 'tele-assessment' approach to the delivery of its assessment modalities. Candidates can sit their examination remotely, close to their place of practice, which reduces the need for rural doctors - both candidates and examiners - to leave their communities for the purpose of assessment. A major component of the assessment process is the Structured Assessment using Multiple Patient Scenarios (StAMPS) examination, which blends the formats of an Objective Structured Clinical Examination (OSCE) and a traditional viva vocè examination. It is a high-stakes assessment, that was designed to be academically rigorous, flexible, valid, reliable, and fair. Since 2008 ACRRM has provided a videoconferencing option to candidates for their StAMPS examination allowing them to remain in or near their home location, while the examiners meet a central location. Travel restrictions due to the SARS-CoV-2 pandemic meant for the first time both candidates AND examiners participated in StAMPS via videoconference. ACRRM conducted an online StAMPS assessment using videoconferencing technology for 65 candidates in mid-May 2020, with all candidates, examiners and support staff remaining in or near their home communities. These Twelve Tips outline some of the experience gained in providing tele-assessment over the past twelve years.

Transanal total mesorectal excision the Gold Coast experience: learning curve and comparison to traditional technique.

BACKGROUND: Laparoscopic and open techniques in rectal cancer are well-published, however, technical challenges remain for mid to low rectal cancer resections in the narrow pelvis. Transanal total mesorectal excision (taTME) has been pioneered to potentially circumvent these challenges. The aims of this study were to evaluate the learning curve associated with our first cases of taTME as well as compare outcomes to that of conventionally performed rectal resections. METHODS: This was a single-centre retrospective study with data collated from all elective resections by the colorectal unit from 2015 to 2017. Primary outcome was completeness of total mesorectal excision and secondary outcomes were intra- and post-operative morbidity and mortality. RESULTS: A total of 43 patients were identified. Of which, 20 underwent taTME. Mesorectal completeness was obtained in only 47.4% in the taTME group compared to 78.3% in the anterior resection group (p = 0.115). 5.9% of patients in our taTME group had positive circumferential resection margin compared to nil in the anterior resection. Conversion rates were greater in the taTME group (15% versus 0%; 0.028). Operative time, length of stay and clavien IV and V complications were greater in the taTME group. CONCLUSION: This study highlights the difficulty in introducing a novel technique given the learning curve. Our results would expect to improve with increased caseload.
