Abstract

Background

Natural orifice translumenal endoscopic surgery (NOTES) could offer multiple advantages compared with the laparoscopic approach. One such potential advantage, not yet proven, is the inferior inflammatory response, which translates into less significant operative stress. This study aimed to compare the immuno-inflammatory response between transgastric NOTES and laparoscopy for simple surgical procedures (oophorectomy) with reference to the cytokine levels.

Methods

For this study, 20 female pigs were randomly assigned to either NOTES or laparoscopic oophorectomy. Seven animals were used as a control group and received only general anesthesia, with no other procedure performed. Blood samples were obtained before surgery, 1 h after the start of the procedure, and at the end of the intervention. The serum levels of IL1β and IL6 were determined using a porcine enzyme-linked immunosorbent assay (ELISA) kit. The mean operative time, intraoperative incidents, and postoperative complications were recorded. On postoperative day 14, the animals were killed, and gastric leak tests were performed.

Results

Both the NOTES and laparoscopic procedures were successfully completed. No gastric leaks were observed during necropsy. The transgastric oophorectomy required a significantly longer time to perform than the laparoscopic surgery. Compared with the NOTES procedures, laparoscopic oophorectomy resulted in significantly higher levels of interleukin-1β (IL1β) (42.34 ± 5.26 ng/ml with NOTES vs 46.93 ± 4.79 ng/ml with laparoscopy; p = 0.028) and IL6 (66.95 ± 7.29 ng/ml with NOTES vs 71.75 ± 4.76 ng/ml with laparoscopy, p = 0.049) during the postoperative phase. No statistical difference was detected between the pre- and postoperative cytokine levels in the NOTES group.

Conclusion

The study findings suggest that pure transgastric endoscopic surgery is a safe approach resulting in less perioperative inflammatory response than laparoscopy in the early postoperative phase.
