Lokális elcsúsztatott subdermalis plexus lebenyplasztika alkalmazása tengerimalac (Cavia porcellus) hátulsó lábán daganateltávolítást követően

Abstract

ÖSSZEFOGLALÁS A szerzők egy 2,5 cm tőszélességű és 3,5 cm hosszú lokális csúsztatott subdermalis plexus lebenyplasztikát alkalmaztak egy tengerimalac jobb hátulsó lábán, miután eltávolítottak egy kb. 2 cm nagyságú trichofolliculomát. A bőrlebeny komplikációmentesen gyógyult. Elhalást a bőrlebenyen és a környező szöveteken nem tapasztaltak. A tengerimalac lábának mozgáspályája nem szűkült be, a láb nem fűződött le. Kóros bőrfeszülés nem jelentkezett, és az elváltozás nem újult ki. A szerzők a tapasztalat alapján a kevésbé rugalmas bőrű tengerimalac lábán is javasolják bőrlebeny használatát. SUMMARY Background: Reconstructive surgery has been studied thoroughly in various species, while in others not so much. There are very few publications on skin flap surgeries performed on guinea pigs. The skin of the guinea pig is fixed, so wound closure can be challenging. A previous study on using single pedicle advancement flaps on the head, neck and paravertebral region of guinea pigs showed that reconstructive surgery can be used, but the legs were not part of the study. Guinea pigs are stocky with very short limbs 5-6 cm in length. To the authors' knowledge single pedicle advancement flaps have not been used for wound closure on the guinea pig’s leg before. Objectives: The authors aimed to investigate whether a single pedicle advancement flap can be used, and surgery successfully performed without complications on the leg of a guinea pig. Materials and Methods: A 4.5-year-old male guinea pig was presented with a 2 cm wide swelling on the right hind leg. Fine needle aspiration cytology was performed, which concluded that the tumour was an infundibular keratinizing acanthoma with bacterial inflammation and surgical removal was recommended. The authors removed the mass and used a single pedicle advancement flap from the abdomen to cover the excision site on the leg of the animal. The “dog eared” tissue that formed due to the flap being pulled back onto the leg was removed. The skin flap was secured with single interrupted sutures. The flap length:base width was 2.5:3.5 cm. Results and Discussion: Histopathology confirmed the excised mass to be a trichofolliculoma, a benign tumour commonly seen in guinea pigs, that did not require further treatment. The skin flap healed without complications. The authors did not see necrosis of the skin flap or surrounding tissues. The range of motion of the guinea pig's leg was not restricted. The skin was not stretched on the animal's body due to the flap, and the lesion did not reoccur. The authors recommend using a single pedicle advancement flap even on the fixed skin of the legs in guinea pig, as this method led to full recovery.
