Safety and Efficacy of Polymeric Clips for Appendiceal Stump Closure

Debilitating genitofemoral neuralgia due to nerve entrapment after appendectomy: A case report

Genitofemoral (GF) neuralgia refers to pain and sensory complaints in the region innervated by the GF nerve. It is a rarely reported condition, often due to iatrogenic causes following inguinal surgeries. In refractory forms, diagnostic reassessment is required to look for possible entrapment of the GF nerve. Here we describe a patient who underwent appendectomy and subsequently developed severe debilitating pain in the region of the right GF nerve. Our patient underwent a second laparoscopic surgery with clip removal, resulting in rapid recovery.

Comparison of Two Stump Closure Techniques in Laparoscopic Appendicectomy: A Single-Centre Prospective Cohort Study

Introduction Acute appendicitis is a frequent illness that manifests as an emergency and most of the cases necessitate surgical intervention. One of the most critical processes in a laparoscopic appendicectomy is the closure of the appendicular stump. For the closure of the stump of the appendix, several approaches have been employed and explored, but the one with the best outcomes has yet to be proved. The purpose of this study was to evaluate the medical results and cost analyses of laparoscopic appendicectomy with two of the commonly used stump closure techniques - ENDOLOOP^® and Hem-o-lok^®. Materials and methods A two-year prospective hospital-based cohort study was conducted from June 2019 to July 2021. All the patients in the study were randomly assigned to one of two experimental arms (ENDOLOOP^® and Hem-o-lok^®). The clinical and follow-up data of these patients were collected and tabulated into a data sheet and analyzed. Results In total, 180 individuals were included in the research (90 in each arm). No statistically significant difference was found in comparing the age, gender or diameter of the appendix among the two groups. The time taken for surgery showed significant differences among the two study groups. The time taken for the procedure in the Hem-o-lok® group was significantly lower than the ENDOLOOP® group (40.3 ± 12.3 minutes vs 50.83 ± 10.5 minutes, p < 0.001). No intraoperative or immediate postoperative complications were noted in either of the groups. The average duration of hospital stay was 2.7 ± 0.9 days in the Hem-o-lok® group, while it was 3.1 ± 0.8 days in the ENDOLOOP® group (p = 0.986). The material cost for the stump ligation with Hem-o-lok® was Rs. 310 ± Rs. 76 while that using ENDOLOOP^® was Rs. 630 ± Rs. 118 (p < 0.001). In the Hem-o-lok^® subset of patients, the mean direct expenses of laparoscopic appendicectomy were considerably lower. During the 12-week follow-up period, none of the patients had any post-operative complications. Conclusion According to the results of this study, both the technical variations of appendix stump closure are equal in terms of postoperative complications. When compared to the ENDOLOOP^® group, the Hem-o-lok® group had a shorter duration of surgery and ended up spending less money. Hem-o-lok® clips have the potential to become the preferred way of anchoring the appendix base during laparoscopic appendicectomy.

Cost analysis of laparoscopic appendectomy in a large integrated healthcare system

INTRODUCTION

Healthcare expenditure is on the rise placing greater emphasis on operational excellence, cost containment, and high quality of care. Significant variation is seen in operating room (OR) costs with common surgical procedures such as laparoscopic appendectomy. Surgeons can influence cost through the selection of instrumentation for common surgical procedures such as laparoscopic appendectomy. We aimed to quantify the cost of laparoscopic appendectomy in our healthcare system and compare cost variations to operative times and outcomes.

METHODS AND PROCEDURES

We performed a retrospective review of laparoscopic appendectomies in a large regional healthcare system during one-year period (2018). Operating room supply costs and procedure durations were obtained for each hospital. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) outcomes and demographics were compared to the costs for each hospital.

RESULTS

A total of 4757 laparoscopic appendectomies were performed at 20 hospitals (27 to 522 per hospital) by 233 surgeons. The average supply cost per case ranged from $650 to $1067. Individual surgeon cost ranged from $197 to $1181. The average operative time was 41 min (range 33 to 60 min). There was no association between lower cost and longer operative time. The patient demographics and comorbidities were similar between sites. There were no significant differences in postoperative complications between high- and low-cost centers. The items with the greatest increase in cost were single-use energy devices (SUD) and endoscopic stapler. We estimate that a saving of over $417 per case is possible by avoiding the use of energy devices and may be as high as $ 984 by adding selective use of staplers. These modifications would result in an annual savings of $1 million for our health system and more than $ 125 million nationwide.

CONCLUSION

Performing laparoscopic appendectomy with reusable instruments and finding alternatives to expensive energy devices and staplers can significantly decrease costs and does not increase operative time or postoperative complications.

Factors affecting the length of hospital stay after laparoscopic appendectomy: A single center study

AIM

This study aimed to explore factors may affect the length of hospital stay after laparoscopic appendectomy.

METHODS

The data of 636 patients undergoing laparoscopic appendectomy between July 2016 and July 2019 in Beijing Tsinghua Changgung Hospital were retrospectively analyzed. The patients were divided into group A (hospital stay ≤3 days, 348 patients) and group B (hospital stay >3 days, 288 patients) according to their hospital stay.Sex, age, disease onset time(time from onset to admission), nausea, vomiting, diarrhea, peritonitis, comorbidities, and history of appendicitis; preoperative body temperature (T), white blood cell (WBC) count, percentage of neutrophilic granulocytes, and preoperative C-reactive protein (CRP) level; time from diagnosis to surgery. appendix diameter, appendicolith, and ascites in ultrasound or CT; surgical time(the surgery start time was the time of skin incision, and the end time was the time the anesthesia intubation was removed), intraoperative blood loss (the volume of blood infiltrating into a gauze was calculated by weighing the gauze infiltrated with water and calculating the volume of water), intraoperative adhesions or effusions, and stump closure methods, convert to open appendectomy, appendix pathology(perforated or gangrenous appendicitis were defined as complicated appendicitis and simple or suppurative appendicitis were defined as uncomplicated appendicitis) and antibiotic treatment schemes were analyzed.

RESULTS

Significant differences were detected between group A and group B in age (37.10 ± 13.52y vs 42.94 ± 15.57y, P<0.01), disease onset time (21.36 ± 16.56 h vs 32.52 ± 27.99 h, P <0.01), time from diagnosis to surgery (8.63 ± 7.29 h vs 10.70 ± 8.47 h, P<0.01); surgical time(64.09 ± 17.24 min vs 86.19 ± 39.96 min, P < 0.01); peritonitis(52.9% vs 74%, P < 0.01), comorbidities (12.4% vs 20.5%, P < 0.01), appendicolith (27.6% vs 41.7%, P < 0.01), ascites before the surgery(13.8% vs 22.9%, P < 0.01), intraoperative adhesions or effusions(56% vs 80.2%, P < 0.01); preoperative temperature (37.11 ± 0.64°C vs 37.54 ± 0.90°C, P < 0.01); preoperative WBC count (13.06 ± 3.39 × 109/L vs 14.21 ± 4.54 × 109/L, P = 0.04);preoperative CRP level(18.99 ± 31.72 mg/L vs 32.46 ± 46.68 mg/L, P < 0.01); appendix diameter(10.22 ± 2.59 mm vs 11.26 ± 3.23 mm, P < 0.01); intraoperative blood loss (9.36 ± 7.29 mL vs 13.74 ± 13.49 mL, P < 0.01); using Hem-o-lok for stump closure(30.7% vs 38.5%, P = 0.04); complicated appendicitis (9.5% vs 45.8%, P < 0.01); and using ertapenem for antibiotic treatment after the surgery(4.3% vs 21.5%, P < 0.01). Multivariate analysis demonstrated that age (OR = 1.021; 95%CI = 1.007-1.036), peritonitis (OR = 1.603; 95% CI = 1.062-2.419), preoperative WBC count (OR = 1.084; 95% CI = 1.025-1.046), preoperative CRP level (OR = 1.010; 95% CI = 1.005-1.015), time from diagnosis to surgery (OR = 1.043; 95% CI = 1.015-1.072), appendicolith (OR = 1.852; 95% CI = 1.222-2.807), complicated appendicitis (OR = 3.536; 95% CI = 2.132-5.863), surgical time (OR = 1.025; 95% CI = 1.016-1.034), use of Hem-o-lok for stump closure (OR = 1.894; 95% CI = 1.257-2.852), and use of ertapenem for antibiotic treatment (OR = 3.076; 95% CI = 1.483-6.378) were the risk factors for a prolonged hospital stay.

CONCLUSIONS

The patient with appendicitis was older and had peritonitis, higher preoperative WBC count or CRP level, longer time from diagnosis to surgery, appendicolith, and complicated appendicitis, predicting a prolonged hospital stay. Shorter surgical time and the use of silk ligation for stump closure and cephalosporins + metronidazole for antibiotic treatment might be better choices to obtain a shorter hospital stay.

Comparison of Polymeric Clips and Endoscopic Staplers for Laparoscopic Appendectomy

INTRODUCTION

Appendectomy is the most common pediatric surgical procedure. To decrease the cost and environmental impact of single incision pediatric endosurgery (SIPES) appendectomy, we switched from using endoscopic staplers to polymeric clips placed with nondisposable laparoscopic appliers. The aim of this study was to compare the resulting reduction in cost and amount of waste generated per case, as well as to compare the perioperative variables and outcomes in patients in whom clips were used, with those of historical patients in whom staplers were used.

MATERIALS AND METHODS

Retrospective chart review of SIPES appendectomies was performed and patients in whom clips were used were compared with patients in whom staplers were used. Demographic, operative, and clinical data were collected. t-Test, Mann-Whitney test, and chi squared test were used to analyze the data as appropriate. The cost to the hospital of the clips and staplers was compared. The disposable waste generated from clips and the staplers was weighed.

RESULTS

A total of 246 patients were included: 111 in stapler group and 135 in clip group. There were no statistically significant differences between the groups in operative time, estimated blood loss, length of stay, and complications. There were no complications related to use of clips. In the clip group, staplers were used in 10% because base of appendix was too large, gangrenous, or perforated and could not be clipped. Use of polymeric clips was less expensive and generated less waste.

CONCLUSIONS

Use of polymeric clips for appendectomy is safe and effective, and results are comparable with those of stapling. Based on our data, in 90% of appendectomies, the base of appendix is amenable to clipping. This study supports use of clips over staplers to decrease cost and environmental impact.
