In Pursuit of the Most Cost-Effective Pediatric Laparoscopic Appendectomy: The Effect of Disposable Instrument Choice on Operative Time and Surgeon-Controllable Cost

Transumbilical laparoscopic-assisted appendectomy in children and adolescents: what have we learnt in more than 1200 cases?

PURPOSE

TULAA combines the laparoscopic and open technique and is considered to be a safe, fast and cost-effective procedure. On the other hand, preparation is limited due to the single instrument, especially in complicated appendicitis. In this study we analyze the outcome of our TULAA patients, focusing on conversion and complication rates.

METHODS

We performed a retrospective study including all patients treated with TULAA in our department between 2006 and 2016. We analyzed patient data, operative data, costs, complications, and conversion rate to standard laparoscopic or open appendectomy.

RESULTS

1275 children and adolescents were enrolled. Mean age was 10.2 years. TULAA was completed in 88% of cases. The overall mean operative time was 33 min. The overall complication rate was 5.7%. The most common complications were wound infection (2.7%), seroma (1.7%) and wound abscess (1.4%). Both the conversion rate and the complication rate were significantly higher in complicated appendicitis. Furthermore, the conversion rate is higher in overweight or obese patients.

CONCLUSION

TULAA is a safe, quick and cost-effective treatment option for acute appendicitis in children and adolescents. The complication rate and conversion rate are significantly correlated with the degree of appendiceal inflammation and comparable other surgical procedures.

Development and assessment of a loop ligation simulator for laparoscopic appendectomy

OBJECTIVE

Loop ligation of the appendix is a challenging surgical skill and well suited to be trained in a simulator. We aimed to develop an affordable and easy-to-build simulator and test its training effect.

DESIGN AND PARTICIPANTS

Different materials were tested, and the best training modality was identified by researching the literature. The developed simulator training was tested on 20 surgical novices.

RESULTS

A video was produced including an instruction on how to build the simulator and a step-by-step tuition on how to ligate the appendix. The Peyton approach was utilized to guide learners. Training with the simulator leads to reliable skill acquisition. All participants improved significantly in completing the task successfully during the structured learning.

CONCLUSION

We succeeded in developing a simulator for loop ligation of the appendix during laparoscopic appendectomy. Participants significantly improve in handling the loops. The transferability of the skill learned during simulation to the operating room will be subject of a follow-up study.

In Pursuit of the Most Cost-Effective Laparoscopic Appendicectomy: A Review of the Literature

PURPOSE

To review the literature and identify the most economical techniques for laparoscopic appendicectomy (LA) that do not compromise on patient care.

METHODS

We performed a search of the Cochrane Library, PubMed, EMBASE and Google Scholar for papers published between January 2001 and January 2021. The outcomes of the included studies were then grouped by theme of cost analysis, with the main areas of focus being the use of disposable equipment, appendiceal stump closure, and retrieval of the appendix.

RESULTS

After screening a total of 254 search results, 40 studies were included, representing 13 285 patient outcomes, having two main areas of focus: the use of reusable or disposable equipment and the different methods of appendiceal stump closure. Use of disposable instruments has been cost effective in LA in 2 studies. However, use of reusable trocars has reduced cost of procedure by €250 in another study. Appendiceal stump closure using ligature, endoloops or Endoclips had been cost-effective compared to Endostaplers in 25 studies. This can save up to €350. Endoscopic specimen bags are single use and represent further disposable equipment costs. The use of a sterile glove to replace this piece of kit can further provide cost benefit as shown in 2 studies.

CONCLUSION

Laparoscopic appendicectomy can be performed in a variety of ways with equivocal patient safety. We present the use of extracorporeal ligature of the appendiceal base, combined with the use of a surgical glove retrieval system as the most economic technique in laparoscopic appendicectomy.

Cost-Effective Approach to the Laparoscopic Appendectomy : Balancing Disposable Instrument Cost With Operative Time

BACKGROUND

Surgeons can help reduce health care spending by selecting affordable and efficient instruments. The laparoscopic appendectomy (LA) is commonly performed and can serve as a model for improving health care cost.

METHODS

We retrospectively reviewed all adult patients who underwent LA for non-perforated appendicitis from March 2015 to November 2017. Our objective was to determine which combination of disposable instruments afforded the lowest total operative cost without compromising postoperative outcomes.

RESULTS

In total, 1857 consecutive patients were reviewed from 2 hospitals. After determining the 8 most commonly utilized combinations of disposable instruments, 846 patients were ultimately analyzed. The combination of a LigaSure, Endoloop, and an EndoBag (LEB) had the shortest median operative time (25 minutes, P < .001) and lowest median total operative cost ($1893, P < .001).

CONCLUSIONS

The LEB instrument combination rendered the shortest operative time, lowest total operative cost, and can be used to maximize surgical value during LA.
