[Prophylaxis of postoperative wound complications]

Area of Science:

• Surgical Pathology
• Wound Healing Research
• Microbiology

Background:

• Postoperative wound complications, including surgical site infections and hernias, pose significant challenges in patient recovery.
• The etiology of these complications is multifactorial, involving intrinsic wound characteristics and extrinsic factors.
• Sutures and suture materials are implicated in the development of eventrations and postoperative hernias.

Purpose of the Study:

• To investigate the etiological factors contributing to postoperative wound complications.
• To elucidate the role of sutures and suture materials in the development of eventrations and postoperative hernias.
• To analyze the interplay of various factors in the pathogenesis of wound complications.

Main Methods:

• Experimental study on animal models (rats, dogs) and human cadavers (corpses).
• Morphological and microbiological analyses of surgical wounds.
• Evaluation of wound characteristics, tissue status, microbial dissemination, and suture material properties.

Main Results:

• Wound complication etiology is determined by a complex interaction of factors, including wound type, tissue trauma, ischemia, devitalized tissue, suture material characteristics, and microbial dissemination.
• The isolated presence of a single factor, such as high microbial load, does not invariably lead to wound complications.
• Critical microbial doses in fresh wounds are not an obligatory factor for suppuration.

Conclusions:

• Postoperative wound complications result from a multifactorial etiology, emphasizing the importance of a holistic approach to wound management.
• Suture characteristics and material properties significantly influence the risk of eventrations and hernias.
• Preventing wound complications requires addressing a combination of local wound conditions and microbial factors, rather than focusing solely on bacterial load.
