Abstract
Background
Creation of extraperitoneal space during TEP repair requires an expensive commercially available balloon.
Patients and methods
Fifty-six patients suffering from uncomplicated primary unilateral or bilateral groin hernia were randomized into two groups; group 1 – indigenous balloon dissection and group 2 – direct telescopic dissection.
Results
There were 55 males and 1 female, with an average age of 49 years; 50% of the inguinal hernias were bilateral. Creation of extraperitoneal space was considered as satisfactory in majority of patients (94.6%) with satisfactory anatomical delineation. Peritoneal breach was noticed during dissection in 36 (64.3%) patients. There was one (3.8%) conversion of TEP to TAPP in group 2. Distance between pubic symphysis to umbilicus was an important factor, which affected the easiness of dissection. In patients with this distance ≤14 cm lateral placement of ports was considered for easy use of graspers. The incidence of scrotal edema was significantly higher in group 2 as compared with group 1 (p < 0.01). Patients with indirect inguinal hernias in group 2 presented with a greater number of scrotal edema. Pain score on VAS at 6 h after surgery was significantly higher in group 2 (p < 0.021). Patients with age <65 years, bilateral hernias, and indirect hernias had a correlation with higher pain score at 6 h. Of the patients, 17.9% developed seroma in group 1 versus 64.3% in group 2 (p < 0.001).
Conclusion
Anatomical delineation of inguinal area and dissection in the extraperitoneal space in TEP repair was equally satisfactory with both low-cost indigenous balloon (group 1) and telescopic dissection (group 2). Balloon dissection was associated with significantly reduced postoperative pain at 6 h, scrotal edema, and seroma formation. However at 3 months follow-up balloon dissection did not offer significant advantage over direct telescopic dissection in the overall long-term outcome of TEP repairs. If balloon dissection is considered useful for the beginner, low-cost indigenous balloon may be used to avoid higher cost of commercially available balloon dissector with added early advantages.
