Comparison of Single-Port Laparoscopic Totally Extraperitoneal Hernioplasty Versus Conventional Laparoscopic Totally Extraperitoneal Hernioplasty : A Single-Center Study.

BACKGROUND

To evaluate the safety and outcomes of single-port laparoscopic totally extraperitoneal (SPLTEP) and conventional laparoscopic totally extraperitoneal (CLTEP) hernioplasty.

METHODS

Retrospectively, we collected patients who underwent a laparoscopic totally extraperitoneal approach. The inclusion criteria were as follows: (1) male patients aged >20 years, (2) untreated hernia, and (3) American Society of Anesthesiologists (ASA) score ≤3. The exclusion criteria included: (1) additional procedures received during surgery, (2) inguinoscrotal hernia, (3) ASA score >3, (4) previous lower abdominal surgery, (5) bleeding disorders, and (6) incarcerated, obstructed, strangulated, or recurrent inguinal hernias. Patients were classified into SPLTEP and CLTEP groups. The demographics, body mass index (BMI), ASA score, comorbidities, blood loss, operation time, postoperative length of stay (LOS)/complications, hernia recurrence, visual analog scale (VAS), and postoperative analgesic requirements were collected for analysis.

RESULTS

A total of 246 patients were enrolled. There were 103 patients in the SPLTEP group and 143 patients in the CLTEP group. The mean age was 56.1 ± 16.2 years versus 57.9 ± 15.1 years. There were no significances in demographics, BMI, ASA score, comorbidities, blood loss, operation time, postoperative LOS/complications, and hernia recurrence. The SPLTEP group had a shorter postoperative LOS, lower VAS at 18 hours postoperation, and a reduced amount of 24-hour postoperative analgesics.

CONCLUSION

SPLTEP hernioplasty is as safe as the CLTEP procedure. In addition, the SPLTEP group had a shorter LOS and a lower VAS score and required less postoperative analgesics. Further studies may focus on long-term complications, hernia recurrence, and chronic pain in these 2 groups.
