Ectopic pregnancies (EP) account for approximately 1% of all pregnancies. Surgical management of such patients should be accomplished through the laparoscopic route. Presently, available data from national studies suggest that only a minority of women benefit from such an approach. Regional studies and single institution reports suggest that trainee involvement in these procedures vary widely. Competency in laparoscopic surgery for EP is a mandatory requirement for independent practice in the UK. In a recent survey of UK trainees of all grades in obstetrics and gynaecology, 53.4% of trainees reported that they were trained or being trained in such procedures. This study examines the perspectives of the trainees. We performed a national questionnaire survey of intermediate- and advanced-level trainees in the UK During a 12-month period, 52% of trainees had performed at least one procedure independently; 80% of trainees performed most of the procedure on at least one occasion. The satisfaction with training was rated as 3 on a five-point Likert scale. Thirty percent of the trainees had access to a laparoscopy simulator. We found a high level of trainee engagement with laparoscopic tubal surgery. The intensity of experience is likely inadequate to satisfy the learning curve. A holistic approach s required to ensure surgical competence.
KeywordsTraining Laparoscopy Ectopic pregnancy
Ectopic pregnancies (EP) account for approximately 1% of all pregnancies, and 95% of these are located in the fallopian tube . Optimal surgical management, based on the evidence of three randomised controlled trials, is achieved through the laparoscopic access [2–4]. In haemodynamically stable patients, current UK guidelines recommend laparoscopic surgery . Presently, available data from two national studies suggest that only 27% and 35% of women were managed by laparoscopic surgery even though 90% of gynaecologists reported that if resources were available, laparoscopic approach could be adopted [6, 7]. In a recent regional study, 84% of patients were managed via laparoscopic surgery . An earlier regional study revealed that 37% of trainees performed laparoscopic surgery for EP, but more recently, an urban single institution experience revealed that 53% of procedures were performed by trainees [9, 10]. With structured enthusiastic effort, over 90% of cases can be managed through laparoscopic route . Competency in laparoscopic tubal surgery for EP is a mandatory requirement for the completion of training. Factors that have impeded rapid uptake and training include reduced exposure following the European Working Time Directive (EWTD), lack of appropriate trainers, theatre resources and implications of clinical governance. With ever wider provision of specialised early pregnancy assessment service and the subsequent conservative or medical management of patients with tubal pregnancy, the opportunities for training in the surgical management of such patients are further reduced. In a recent survey of UK trainees of all grades in obstetrics and gynaecology, 53.4% of trainees reported that they were trained or being trained to manage ectopic pregnancies laparoscopically; however, 47.3% said they had not performed surgery for ectopic pregnancy in the preceding 12 months . In the same report, the proportion of trainees who said that supervision in theatre for all procedures was good or very good was 57%; this has remained stable since the first such survey in 1995. Since laparoscopic surgery for EP is a common procedure, a study of this from a trainee’s perspective could be informative regarding the management of training.
Our questionnaire study aims to provide a measure of the surgical experience gained by the trainees and their perception of the quality of training across the specialty with regard to laparoscopic management of EP.
Materials and methods
With the approval of the Royal College of Obstetricians and Gynaecologists (RCOG) Honorary Secretary, a questionnaire was posted to specialist registrars or specialty trainees who had completed basic training for at least 2 years and were in the process of obtaining core (Specialty Trainee 3–5) or advanced level (Specialty Trainee 6–7) training within the UK in 2009. Each trainee was sent a cover letter, questionnaire (see Appendix) and a stamped addressed envelope for return. The postal communication was handled by the hospital clinical audit department. A reminder letter was not sent to nonresponders; this preserves anonymity, and although a reminder may improve the response rate, it is unlikely to affect the overall findings. The questionnaire requested information from trainees regarding their grade, length of training, the extent and depth of their involvement in laparoscopic salpingectomy during the preceding 12 months, method of tubal salpingectomy, practice of salpingotomy, attendance at a laparoscopy course and availability of a laparoscopic simulator. In addition, our study illustrates the self-assessed competency level with regard to laparoscopic salpingectomy. In addition a five-point Likert scale, a widely used validated subjective assessment tool, was used to gauge the trainees’ level of satisfaction with training and whether they anticipated attaining competency in laparoscopic tubal surgery prior to completion of training. On this scale, a score of 1 indicates a negative response and 5 indicates a positive response.
A total of 645 questionnaires were posted to registrar level trainees in obstetrics and gynaecology across the UK. Two hundred four responses were received (31.6%). Thirteen of the respondents had been appointed as consultants, and therefore, these responses were excluded from the analysis. Fourteen (7.3%) respondents were at specialist trainee (ST) level 3, 29 (15.2%) at ST4, 38 (19.9%) at ST5, 44 (23%) at ST6 and 56 (29.3%) were at ST7. A further ten (5.2%) were categorised as other as a grade was not specified, and their response is included in the analysis.
During the preceding 12 months, the median number of laparoscopic procedures for tubal ectopic pregnancies where a trainee was involved was four (interquartile range (IQR), 2–8). During the same period, the median number of procedures where the trainee performed the procedure at level 4 competency was three (IQR, 1–7). One hundred trainees had performed at least one laparoscopic tubal surgery at level 5 competence. Similarly, 54 trainees performed at least one procedure at level 4 competency, 26 trainees at level 3 and further ten trainees at level 2. One trainee did not respond to this question.
In terms of tubal preservation, 82 (43%) trainees reported that they performed salpingotomy when appropriate, whilst 98 (51%) did not perform such a procedure; 11 (6%) did not provide a response to that question. With regard to the method of excising the fallopian tube, 81 (42%) trainees reported that they preferred endoloop ligature and excision, 96 (50%) preferred diathermy excision, 6 (3%) used both of these techniques and the remaining 8 (4%) did not respond.
Ninety (47%) trainees had attended a level 2 RCOG-recognised or equivalent laparoscopy course within the preceding 2 years; the remaining 101 trainees had not attended such a course during this timeline. Fifty-seven (30%) trainees reported that they had access to a laparoscopic simulator at their place of work; the remaining134 (70%) trainees did not have such facility.
Summary of UK literature regarding surgical access and trainee involvement in tubal pregnancy surgery
Free comments from the survey
In summary, comments suggested that university hospitals are more likely to provide a ‘satisfactory’ training. Additional factors which are perceived to influence the quality of laparoscopic training include rota arrangements which tend to favour the most senior trainees with respect to gynaecologic surgery, commitment from trainers and fluency of trainers in performing such procedures. Many trainees cited out of programme training in minimal access surgery as the most reliable solution.
Clinical training, surgical education, workforce planning, patient safety and clinical governance are intertwined issues which concern all stakeholders. Composition, quality and delivery of training seem to preoccupy trainees as well as trainers. These issues are increasingly brought into focus as the duration and intensity of exposure of the trainees to clinical practice have declined. Legislation such as the EWTD and importantly the changing nature of gynaecological practice has had a major impact on training. In the UK presently, the emphasis on training is focused on improving the delivery of acute care such as intrapartum care and early pregnancy complications. Appropriate management of ectopic pregnancy is an important element of this care. This survey provides a ‘snapshot’ of trainees’ perspective with regard to laparoscopic management of EP.
Overall response rate was 31.6%, and effective response rate was 29.6%. In this group, 42.4% of the respondents were within the junior registrar ranks, and 52.3% were senior registrars; the remaining 5.2% were non-career grade doctors who effectively function as registrars in the provision of service. During the preceding 12 months, 15 (7.9%) trainees said they had not been involved in a single procedure. The median number of procedures that a trainee was involved in was 4, and that where they performed at least most of the procedure was 3. During the same period, 147 (77%) trainees had performed most or all of at least one procedure under supervision. The RCOG survey had 1,001 respondents, which equated to about 66% of all trainees in the UK. Among this group of respondents, 30% were in ‘basic’ training and a further 10% represented a miscellaneous group of trainees who were lecturers, subspecialty trainees and research fellows; these subgroups were not targeted by our study as they would not have been suitable subjects. The target group of our study corresponds to the remaining 60% of that study. The RCOG trainees’ survey reported that 47.3% of trainees had not performed any procedure during a 12-month period . This discrepancy could be explained by the differing target groups of the surveys and potentially the phrasing of the question; in our survey, a graded response was possible with regard to the level of involvement, which was not the case with the RCOG survey. Further, amongst our group, 180 (94.2%) trainees had performed some component of at least one procedure. This lends weight to the finding that 90% of units felt that they could offer laparoscopic surgery for EP if adequate resources were available .
With regard to conservation of the tube, 51% of the respondents do not perform salpingotomy. A simulator-based assessment of salpingectomy revealed a learning curve in terms of time taken per procedure to reach a plateau to be up to 6 procedures for experts, 21 for intermediates and 27 for novices . Although there are no similar data available for salpingotomy, but due to the need for a broader range of laparoscopic skills, it is our opinion that the likely learning curve for salpingotomy will be steeper. This will have implications for training and provision of such service by a generalist on an ad hoc basis. Conservation of the tube assumes clinical significance for psychological reasons or if the contralateral tube is diseased.
In this survey, 50% of the trainees preferred diathermy excision, whilst 42% preferred endoloop; the remainder used both techniques. A randomised controlled trial of salpingectomy by means of endoloop versus electrocautery demonstrated that with endoloop, operation takes shorter, a patient has less pain and lesser total analgesia requirement by day 7 . Perhaps, trainees could be encouraged to utilise a technique which benefits the woman and optimises the use of operating theatre time. It is worth noting that Endoloop technique leads to a partial salpingectomy, whilst electrocautery offers the opportunity to perform total salpingectomy; tubal stump ectopic pregnancy could indeed be an extremely rare complication.
The RCOG-approved intermediate-level laparoscopy courses provide theoretical as well as practical teaching. There is some evidence that such courses can enable development and retention of skills [15, 16]. Longitudinal impact and potential need for reiteration have not been studied over a significant period, but at least annual verification would be necessary . In our survey, only 47% of registrar level trainees had attended such a course within a 2-year period. Following instruction in laparoscopic surgery, consolidation in the form of practice would be required. It is well established in the literature that surgical complications decline with progression along the learning curve; this is indeed the case in laparoscopic surgery, where most problems tend to occur during the early learning phase [18, 19]. Both for logistical advantage and in the interest of patient safety, trainees should familiarise themselves with the instruments and make grounds on the learning curve prior to the clinical encounter of an acutely ill patient. In this respect, evidence from randomised clinical trials demonstrates that skills learnt with the aid of a simulator can be successfully transferred to the operating theatre [20–22]. In this study, 57 (30%) trainees reported having access to a simulator facility. This confirms the similar finding in a regional study regarding access to a simulator . The same study revealed that although 81% of the respondents felt simulator training was essential in improving laparoscopic skills, trainees did not make adequate use of facilities where they existed .
Psychomotor skills can be learnt through courses and refined through simulation practice and later in the operating theatre. One option that might increase usage of simulators is if they are made available at a regional level with nominated supervisors for dedicated sessions. RCOG is currently examining the role of simulators in formal training. A regional study from the UK revealed that all hospitals had the necessary laparoscopic equipment; so, simulator training could be a meaningful adjunct in augmenting training across the board . The potential value of a simulator in such training is further emphasised by the anecdotal evidence that increasing medical or conservative management of patients with ectopic pregnancy reduces the opportunity for surgical training in theatre.
Knowledge base should be expanded by courses, local educational activities and web-based resources, to name a few. In this study, only 47% of the trainees had attended a suitable course within a defined time period.
In the UK, trainees are required to undergo regular objective assessment—OSATS. Implementation of this tool creates an interaction between the trainee and the supervisor, where various aspects of trainees’ performance are assessed. This tool has proven its value in improving the trainees’ understanding and improvement in performance . The secondary effect of this tool in increasing the direct supervision and systematic discussion of trainees’ performance is a key feature facilitating ‘formative assessment’.
In Table 1, we have summarised the published data regarding trainee involvement in the laparoscopic management of tubal pregnancy in the UK over the last decade. It would appear from these articles that a high proportion of tubal pregnancies can be managed through the laparoscopic route. From this limited information, it is not clear how the trainee involvement is changing in the wider context. Of course, practitioners’ willingness to submit their data and publication bias must be borne in mind when interpreting the wider trend.
Our national survey of trainees demonstrates that there is a high level of trainee engagement in laparoscopic surgery for ectopic pregnancy. Despite the variable satisfaction with the training aspects, majority anticipate attainment of competency by the end of the training period. With increasing standardisation of training, use of objective assessment tools and increasing consultant presence, we anticipate all trainees will become versed in laparoscopic surgery for ectopic pregnancy. This would be more likely to be achieved if simulators are formally integrated within the gynaecological surgery training syllabus. This will be realised once a steady state of all the necessary resources has been established.
