Table 1
Tissue changes caused by various surgical devices immediately after incision.
| Histological Observation | Surgical devices | Tissue-welding device | Laser | Electrocoagulator | Radiofrequency device | Scalpel |
| Wound edge (Figure 1) | Uneven | Smooth straight with yellow to black pigment accumulation (carbonization) | Uneven | Uneven, torn | Smooth, slightly uneven |
| Cellular changes (Figure 2) | Obscured and disorganized, stretched nuclei, karyolysis | Obscured and disorganized, stretched nuclei, karyolysis | Obscured and disorganized, stretched nuclei, karyolysis | No visible changes | No visible changes |
| Tissue changes | Cleft formation and cell separation | Deep clefts, vacuolation, and cell separation | Cleft formations filled with red blood cells, vacuolation, and cell separation | Cleft formation, cell separation, and vacuolation | Cleft formation, cell separation |
| Capsule | Vacuolation, hyalinization of collagen (Figure 3) | Vacuolation and cell separation | Total separations of the capsule from the parenchyma | Total separations of the capsule from the parenchyma | Total separations of the capsule from the parenchyma |
