Experimental use of a novel single-port gasless laparoendoscopic operative field formation device.

ABSTRACT:

Introduction

Traditional laparaendoscopic surgery using CO2 pneumoperitoneum is associated with complications and the existing gasless laparaendoscopic surgery has shortcomings such as poor visibility in the operation field. To overcome the disadvantages of the current lifting gasless laparaendoscopic operation platforms, we developed an inflatable device for gasless laparoscopic operation field formation (LOFF) that can be internally installed and applied in practice.

Methods

We initially designed operation platforms for gasless laparaendoscopic single-port (GLESP) surgery. Subsequently, a triangular prismatic LOFF device was selected and applied successfully to GLESP cholecystectomy of five pigs. Ultimately, using pigs as a model, three surgical approaches (LOFF-assisted laparaendoscopic single-site (LOFF-LESS), LESS surgery, and traditional lifting (GLESP) were compared, and the advantages and drawbacks of inflatable devices for gasless laparoscopic operation field assessed.

Results

The use of the LOFF device in GLESP cholecystectomy was first evaluated. The time for surgical space formation (4.4 ± 1.2 and 4.8 ± 1.0), the operating time for gallbladder removal (25.2 ± 4.8 and 25.4 ± 2.7), and the loss of blood (9.4 ± 3.1and 9.2 ± 2.4) was similar between LESS and LOFF, respectively (Table 2). In contrast these parameters were higher in GLESP (6.6 ± 1.0, 30.3 ± 4.4 and 10.1 ± 2.0, respectively. The LOFF-LESS surgery exhibited a clearer exposure of the surgical field and shorter operating time than the GLESP surgery. LESS technology showed less postoperation pain, fast recovery, and extremely high cosmetic satisfaction.

Conclusion

The LOFF device provides a safe, effective, and feasible operation platform that can be internally installed and inflated for GLESP surgery during cholescytectomy in animal models.

Project description:BackgroundBreast fibroadenoma is the most common benign breast tumour. This study aimed to investigate the advantages and disadvantages of endoscopic-assisted resection via a gas-less transaxillary single-port approach for breast fibroadenoma in adolescent patients, compared with a traditional approach.MethodsThe clinical data of 83 patients with breast fibroadenoma treated in our hospital from October 2019 to October 2021 were collected for retrospective analysis. These patients were divided into an endoscopic-assisted surgery (ES) group (n = 39) and a traditional open surgery (OS) group (n = 44) according to the surgical approach. The operative time, intraoperative blood loss, incision length, postoperative complications, and patient satisfaction were compared between the two groups.ResultsThe surgical cost was (5.1 ± 0.6) thousand Yuan [(0.7 ± 0.1) thousand US dollars] in the ES group and (3.5 ± 2.7) thousand Yuan [(0.5 ± 0.4) thousand US dollars] in the OS group, showing a statistically significant difference (p < 0.001). There was no significant difference in surgical time, intraoperative blood loss, incision length, or the rate of postoperative complications between the two groups. Stratified analysis revealed that the ES group had a significantly shorter operative time [(57.00 ± 10.26) min vs. (78.27 ± 7.63)] (p < 0.001), a smaller incision length [(3.73 ± 0.34) cm vs. (4.42 ± 0.44) cm] (p < 0.001), and a lower complication incidence rate (11.1% vs. 63.6) (p = 0.011) than the OS group in the cases with a nodule number ≥ 3. The satisfaction score using the BREAST-Q scale indicated that psychosocial well-being and patient satisfaction with the breast in the ES group were significantly superior to those in the OS group [(91.18 ± 3.12) points vs. (87.00 ± 4.45) points and (91.03 ± 6.80) points vs. (84.45 ± 6.06) points, respectively] (p < 0.001).ConclusionES is a safe and effective method for the treatment of fibroadenoma. In patients with multiple fibroadenomas (≥ 3 tumours), ES has a shorter operative time and fewer postoperative complications. ES demonstrates a significant, prominent advantage in cosmetic appearance. However, it should be noted that ES is associated with higher costs than OS.
