Single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) for inguinal hernia with prolapsed ovary

Background Most studies reporting the outcomes of laparoscopic ovarian prolapsed hernia operations with large sample sizes are based on intracorporeal closure, while studies on extraperitoneal closure have limited sample sizes. We proactively used the single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) technique and obtained favorable outcomes, which we report in this paper. Methods We retrospectively reviewed patients who had undergone laparoscopic surgery for inguinal hernia at our institution. They were retrospectively classified into two groups based on the pre- or intraoperative diagnosis of hernia with a prolapsed ovary, namely the prolapse group and the non-prolapse group, respectively. The data were statistically analyzed and p < 0.05 was considered statistically significant. Results A total of 771 subjects underwent SILPEC during the study period, including 400 girls. Among them, 63 girls were diagnosed with an ovarian prolapsed hernia. SILPEC was successfully performed through a single port in all cases, with a single exception, in whom the forceps was inserted directly through the right lower quadrant to pull up the ovary. The duration of surgery in the prolapse group was not higher than that in the non-prolapse group. During the SILPEC surgery, the ovaries were successfully reverted into the abdominal cavity by external compression of the inguinal area alone in 38 of the 63 patients. In the remaining 25 cases, the ovaries were reverted into the abdominal cavity by external compression of the inguinal area and traction of the round ligament with forceps. None of these cases failed to return to the ovaries. Conclusion Our study results indicate that SILPEC may be performed safely for the treatment of ovarian prolapsed inguinal hernia. Since the ovary and fallopian tube are close to the internal inguinal ring due to the short round ligament, the procedure requires careful suturing with traction of the round ligament.

Automated summary

Most studies on laparoscopic ovarian prolapsed hernia operations focus on intracorporeal closure with limited sample sizes, while our study demonstrated successful outcomes using the single-incision laparoscopic percutaneous extraperitoneal closure technique. The procedure of SILPEC was safely performed for the treatment of ovarian prolapsed inguinal hernia, with successful reversion of the ovaries into the abdominal cavity in all cases.
