Optimization of the technique for removal of benign tumors and wound suturing in a general surgical hospital

Aim. To improve the results of surgical treatment in patients with large lipomas by using the device for closing the edges of wounds, allowing local preventive hemostasis in the surgical wound area, to create optimal conditions for atraumatic suturing and thereby reduce the amount of intraoperative bleeding and subsequently reduce the amount of postoperative wound complications.

Methods. The results of treatment of 105 patients with different localization of large lipomas were analyzed. Lipomas ranged from 8.0 to 20 cm in diameter. All patients were divided into 2 groups: the control group consisted of 53 (50.5%) patients for which used the traditional technique of tumor excision with closing surgical wounds, and the study group with 52 (49.5%) patients, for which to reduce tissue damage during tumor removal and the edges of wound suturing, one of the device variants developed by us was used, approximation-distraction device. Fisher's exact test was used for the comparison of the outcomes rate, a p-value <0.05 was considered statistically significant.

Results. Surgical wound complications occurred in 7 (6.7%) of 105 patients. In the study group, surgical wound complications occurred in 1.9% (1 observation), in the control group 11.3% (6 observations). Surgical wound complications were severity grade I and grade IIIa. Complications of the first grade did not require a debridement and will regress on its own; in grade IIIa complications, an opening, excision and drainage surgical wounds were performed without general anesthesia.

Conclusion. Moderate local selective near-tumor tissue compression that occurs when the device branches come closer to each other accelerates spontaneous thrombus formation in damaged small vessels. This creates favorable conditions for the surgeon to work in a “dry” wound.
