Does presentation at the Registrars' Papers Day predict future publication?

There are research requirements for trainees to be eligible to present for their final examinations (Fellowship of Royal Australasian College of Surgeons, FRACS). One option is the presentation of a paper or poster at a meeting of which abstracts are subject to review and selection. This includes presentation at the annual Registrars' Papers Day (RPD) in New South Wales. There has been some debate surrounding whether research requirements are fulfilled by presentation at such meetings. Publication in a peer-reviewed journal should be the ultimate aim. A high publication rate will validate the quality of the meeting. All abstracts submitted to the RPD in 1998 and 1999 were analysed. A Medline search was performed in 2005 to identify publication of these presentations in a peer-reviewed journal. Variables of the study that were potentially predictive of subsequent publication were analysed. This included type of presentation, surgical specialty, clinical or laboratory-based study, study design (prospective or retrospective) and sample size. Chi-squared test with Yates' continuity correction was used to compare two independent proportions and significance was set at P < 0.05. The publication rates were: oral presentations 50% (17/34), poster presentations 39% (9/23) and rejected presentations 20% (2/10). The mean and median time to publication was 23.8 and 21.0 months. Prospective design was the only variable identified to have a statistically significant effect on the publication rate (P < 0.002). The most common publishing journal was the Australian and New Zealand Journal of Surgery (12 of 26). Overall consistency (author and study sample consistency) from presentation to publication was 32%. The overall 46% publication rate of this state-based trainees-organized meeting compares favourably with international meetings. The research requirement of the Royal Australasian College of Surgeons (RACS), which includes presentation at the RPD in New South Wales, produces good quality papers for publication.

Diverticulectomy is inadequate treatment for short Meckel's diverticulum with heterotopic mucosa.

BACKGROUND: Meckel's diverticulum is a vestigial remnant of the vitellointestinal duct that may occasionally contain heterotopic gastric mucosa thought to arise from residual yolk sac cells. This may cause significant rectal bleeding, the source of which may be difficult to identify. The present paper addresses the question of whether the choice of resection technique should depend on the macroscopic appearance of the Meckel's diverticulum. METHODS: A retrospective analysis of patients with resected Meckel's diverticulum at Prince of Wales and Sydney Children's Hospitals between 1992 and May 2003 was performed. The external appearance was expressed as a height-to-diameter ratio (HDR) and the presence or absence of macroscopic thickening was recorded. The morphology was then correlated with the presence and site of the heterotopic gastric mucosa (HGM). RESULTS: Seventy-seven patients were identified with an age range between 1 day and 92 years. Fifty-seven (74%) of the patients were men. Presenting symptoms were gastrointestinal bleeding (11.7%), diverticulitis (15.6%), volvulus (2.6%), intussusception (10%) and umbilical fistula (7.8%). Fifty-seven per cent of the resected Meckel's diverticulae were found incidentally. Eight patients underwent a technetium pertechnate nuclear Meckel's scan. The Meckel's scan detected only two of seven patients with HGM on pathological examination. Twenty-nine (38%) patients underwent diverticulectomy and 48 (62%) small bowel resection. Ectopic mucosa was found in 25 (32.5%) patients. Of the Meckel's diverticula that were defined as long (HDR >or=2.0) and containing HGM, five of five (100%) had the ectopic mucosa in the diverticular tip and body only. Of those that were short (HDR <2.0) there was a wide distribution of HGM sites with 12 (60%) involving the whole diverticulum including the base and eight (40%) involving the tip and body only. The presence or absence of macroscopic thickening was described in 18 resected Meckel's diverticula. Thirteen (72%) were described as thickened in the operation report and six of these 13 (46%) were found to have HGM. One of the seven (14%) Meckel's diverticulae with HGM was thought to be of normal appearance and was therefore undetected. CONCLUSION: Simple transverse resection is not recommended for the short Meckel's diverticulum. A HDR of 2.0 is recommended as the cut-off when deciding on the most appropriate operation. The external appearance of the Meckel's diverticulum does not predict the presence of HGM and is therefore an unreliable indicator to aid resection decisions when presented with an incidental Meckel's diverticulum.
