Whose appendicectomy?--Do laparoscopic appendicectomies impair SHO training?

How does the number of training years in pediatric surgery affect appendectomy outcomes?

INTRODUCTION

Appendectomy has traditionally been considered as a training operation for junior pediatric surgeons during their training period. However, with the increase of laparoscopic appendectomy, there has been a growing concern about the performance of this procedure by junior trainees. Our aim is to analyze intra-/postoperative appendectomy outcomes according to the number of training years during Pediatric Surgical residency training program.

METHODS

A retrospective study was performed in patients who underwent appendectomy between 2018 and 2021 in our institution, who were divided into 5 groups according to the number of training years of the junior surgeon who performed the intervention (Y1-Y5). Demographics, complicated appendicitis rate, operation time, and postoperative complications were compared. A stratified analysis according to the technique performed (open/laparoscopic) was performed.

RESULTS

A total of 1274 appendectomized patients were analyzed, of which 1257 (98.7%) were operated on by junior trainees (81 in Y1; 407 in Y2; 337 in Y3; 261 in Y4; and 171 in Y5) without demographic differences between groups. As the year of training increased, an elevation in complicated appendicitis rate was observed, although without statistically significant differences. However, laparoscopic/open appendectomies ratio increased with increasing year of training (p < 0.001). Operative time decreased significantly with increasing year of training (p < 0.001), both in open and laparoscopic appendectomies. There were no significant differences in postoperative complications, nor in the stratified analysis according to surgical technique.

CONCLUSION

Appendectomy performed by junior pediatric surgery trainees can be considered a safe procedure from the first year of training, regardless of the technique used.

Safety assessment of open appendectomies for complicated acute appendicitis in children: a comparison of trainees and specialists

PURPOSE

The aim of this study was to compare the outcome of children with complicated acute appendicitis (CAA) who underwent open appendectomy (OA) performed either by trainees under the direct supervision of an SPS, or an SPS.

METHODS

Two hundred thirty eight patients with CAA were reviewed operated on either by a junior trainee (JT) or a senior trainee (ST) under the direct supervision of an SPS or by an SPS. The outcome measures were the overall rate of complications, operative time (OT), length of hospital stay (LHS) and 30-day readmission rate.

RESULTS

No statistical differences were observed between the three groups regarding the overall complication rates and 30-day readmission rate. Although, no statistical differences were observed in the mean OT between the three groups, the mean OT for perforated appendicitis (PA) performed by JTs was significantly longer than when performed by SPSs (p 0.012). Furthermore, there was a statistically significant difference between JTs and SPSs in terms of LHS for patients with PA (p 0.028).

CONCLUSION

This study suggests that no statistical differences were observed between the supervised trainees and SPSs regarding the overall complication rate and 30-readmission rate when they performed OA for GA or PA except of a longer OT and LHS for PA performed by JTs.

Clinical NOTES appendectomy study: comparison of transvaginal NOTES appendectomy in hybrid technique with laparoscopic appendectomy

PURPOSE

The proposed advantages of NOTES are aimed to assess the comparison with standard procedures. Complications are a major focus of its evaluation. We initiated a prospective comparison between transvaginal hybrid appendectomy versus laparoscopic appendectomy.

PATIENTS AND METHODS

For each, NOTES and laparoscopic appendectomy, 10 consecutive female patients participated in the study with follow-up documentation for 35 days and after 1 year. Transvaginal appendectomy was considered a non-standard medical procedure and required individual patient's consent. Pre- and postoperative gynecological examinations were performed. Questionnaire-based evaluation included issues related to quality of life in addition to objective clinical findings. The study is approved by the ethics committee of the University of Rostock.

RESULTS

All women returned questionnaires for evaluation. Age and BMI are comparable. Overall procedure time was significantly shorter in laparoscopy. The only postoperative complication consisted of an intra-abdominal abscess after laparoscopic appendectomy. One patient of the NOTES group suffered from new abdominal pain 3 weeks postoperatively; a mini-laparoscopy showed a normal situation. Significant differences (p < 0.05) of the questionnaire-based comparison with advantages for the NOTES group were found in following items: reduced activity at day 1-14, postoperative pain at day 1, general health conditions at day 1-3 and quality of life at day 3. NOTES patients wished significantly earlier to be discharged and started significantly earlier with activities, but no differences existed after 4 weeks.

CONCLUSIONS

Transvaginal flexible appendectomy appears to be a safe procedure performed in hybrid technique. Data from the study point to shortened recovery intervals and improved quality of life.

[Open appendectomy. When do we still need it?]

Acute appendicitis is the most common emergency visceral surgical procedure in Germany with 130,000 appendectomies. The question of which operational procedure should be used must therefore be discussed at regular intervals. In many centers of minimal invasive surgery, laparoscopic appendectomy (LA) is the standard procedure. Nearly 30 years after introduction of LA, it is believed that open appendectomy (OA) is needed only on rare occasions, but the actual percentage of OAs carried out in 2006 was 46% of all appendectomies. This high percentage documents that OA is still the standard procedure in many German hospitals. A review of the literature shows that there are still some situations in which OA is superior to LA. Infants younger than 5 years old have a more difficult basic requirement for LA due to the small abdominal cavity, therefore OA is the procedure of choice in most cases. During pregnancy OA has a lower risk for the fetus than LA. Cost analyses show that OA is less expensive for the hospital in material costs, whereas LA is the better economic choice due to an earlier return to work. In summary, there are only marginal differences between the two procedures since both offer a fast patient recovery. Advantages in favor of both LA and OA exist in subgroup analyses and the possible subgroups that can benefit from OA are discussed in this article.

Laparoscopic appendectomy performed by residents and experienced surgeons

BACKGROUND

Laparoscopic appendectomy is widely performed by surgical residents, but its changing indications and outcomes have been poorly investigated. The aim of this study was to examine whether a difference exists in indications and outcomes between laparoscopic appendectomies performed by residents and those performed by experienced surgeons.

METHODS

Between 1999 and 2007, 218 laparoscopic appendectomies were performed and recorded. Data were analyzed to compare operations performed by residents with those by experienced surgeons in terms of indications for surgery and severity of disease. Moreover, laparoscopic appendectomies were thoroughly compared regarding outcomes and complications.

RESULTS

The residents had fewer conversions with laparoscopic appendectomy (8% vs 17%, P=0.04), and similar complication rates (12% vs 13%, P=0.16), compared with experienced surgeons. The median operating time was also comparable (67 minutes vs 60 minutes, P=0.23). However, patients operated on by residents had more emergencies (86% vs 70%, P=0.009), included more foreigners (27% vs 15%, P=0.03), and had intermediate to severe diseases, (81 vs 52%, P<0.001) than patients did operated on by experienced surgeons.

CONCLUSIONS

Surgical residents performed more emergency laparoscopic appendectomies on foreign patients suffering from intermediate to severe diseases compared with experienced surgeons, with comparable surgical outcomes and lower conversion rates.
