Background:
The abdominal wall in groin area is conventionally considered that it was comprised by 9 layers. Single incision laparoscopy totally extraperitoneal hernioplasty (SIL-TEP) reported before were operated through the front of the posterior rectus sheath.
Method:
102 SIL-TPP were conducted from October 2018 to October 2020 at The Affiliated Hospital of Medical School of Ningbo University using a self-made single-port device and standard laparoscopic instruments. Clinical data, demographic and intraoperative findings, and short-term postoperative outcomes were analyzed.
Results:
Of the 102 hernias treated, 46 were right inguinal hernias, 33 were left inguinal hernias and 23 were double-side inguinal hernias. All patients received the SIL-TPP and no conversion happened. The mean left-side and right-side hernia operative time was almost same. The left-side and right-side operative time were 75.48 ± 26.95 and 76.24 ± 26.09 minutes, respectively. The mean operative time was 75.92 ± 26.45 (range, 29-170 minutes) in unilateral inguinal hernia. Mean operative time was 104.17 ± 28.58 minutes (range, 67-180 minutes) in double-side inguinal hernia. The intraoperative complications rate was 21.57 (22/102) and all the complications were Peritoneum or sac tearing. Postoperative complications occurred in 3 cases (1 case wound seroma, 1 case urinary retension and 1 case upper respiratory infection) and were successfully treated conservatively. The mean hospital stay was 2.8646 ± 1.38 days. The 24 hours Visual analogue scale score was 2.28 ± 0.77. During follow-up to June 2022, no recurrence case occurred.
Conclusion:
SIL-TPP is safe and feasible. SIL-TPP has its unique skills and advantages to treat inguinal hernia. Large-scale randomized controlled trials comparing SIL-TPP inguinal hernia repair with conventional single port and conventional three port laparoscopic totally extraperitoneal hernioplasty with short-term outcome and long-term recurrence rate are needed to confirm these results.
