Facial reconstructive surgery after tumour removal in a guinea pig (Cavia porcellus)

A 2-year-old male guinea pig (Cavia porcellus) presented with a pea-sized swelling on his right labium. The tumour was excised and reconstructive surgery was performed using a single pedicle advancement flap, leaving the bottom of the lip intact on account of it being essential for food apprehension and manipulation. Two parallel skin incisions were made in the rostrocaudal direction for almost half the length of the head and the resulting skin flap was carefully undermined, to avoid damaging the follicles and the muscles of the whiskers. The flap was carefully sutured over the excisional defect and at 1.5 months post-surgery, only a small residual scar remains. The lips are intact, the surgical site is covered with fur and many of the whiskers have regrown. Histopathology showed the excised mass to be a grade 1 soft tissue sarcoma, most likely a malignant peripheral nerve sheath tumour.

SummaryWe present two case reports concerning patients who had to undergone surgical treatment according tp the diagnosis of thrombophlebitis with insufficiency of the greater saphenous vein and putative encapsulated haematoma in the lower left leg area. During the operation we found tumours with urgent suspicion of malignancy. The histological examination revealed the diagnosis of mesenchymal chondrosarcoma and malignant peripheral nerve sheath tumour which are extremely malignant, but very rare neoplasmas with unfavourable prognosis. Conclusion: Since both types of tumours are often located below the knee, phlebotomists and vascular surgeons should take them into account as differential diagnosis.

Abstract Introduction and hypothesis This study aimed to investigate the evaluation and management of complications after pelvic floor reconstructive surgery for pelvic organ prolapse in China. Methods Complications of pelvic floor reconstructive surgery for pelvic organ prolapses from 27 institutions were reported from November 2017 to October 2019. All complications were coded according to the category-time-site system proposed by the International Urogynecological Association (IUGA) and the International Continence Society (ICS). The severity of the complications was graded by the Clavien-Dindo grading system. Four scales were used to evaluate patient satisfaction and quality of life after management of the complications: the Patient Global Impression of Improvement (PGI-I), the Pelvic Floor Impact Questionnaire Short Form (PFIQ-7), the Pelvic Organ Prolapse Symptom Score (POP-SS), and a 5-point Likert-type scale that evaluated the patient’s choice of surgery. Results Totally, 256 cases were reported. The occurrence of complications related to transvaginal mesh (TVM) and laparoscopic sacrocolpopexy (LSC) had a significantly longer post-surgery delay than those of native tissue repair surgery (p < 0.001 and p = 0.010, respectively). Both PFIQ-7 and POP-SS score were lower after management of complications (p < 0.001). Most respondents (81.67%) selected very much better, much better, or a little better on the PGI-I scale. Only 13.3% respondents selected unlikely or highly unlikely on the 5-point Likert-type scale. Conclusions The occurrence of complications related to TVM surgery and LSC had a longer post-surgery delay than native tissue repair surgery. Long-term regular follow-up was vital in complication management. Patient satisfaction with the management of TVM complications was acceptable.

Peripheral Nerve Sheath Tumour

AbstractThe aim of this report is to describe an unusual localization of nerve sheath tumour (NST), clinical presentation, imaging, surgical management, and outcome in a 2-year-old dog. A 2-year-old female American Staffordshire Terrier presented with nonambulatory paraparesis, thoracolumbar hyperaesthesia, hindlimb hyperreflexia, and mild muscle atrophy. Computed tomography and magnetic resonance imaging revealed an extradural mass at T7-T8, without vertebral lesions. Surgical treatment consisted in resection of the soft tissue mass through dorsal laminectomy. The dog was ambulatory within 24 hours and free of recurrence at 18 months postoperatively. Histopathologic and features of immunohistochemistry were consistent with NST. The NST of this report was similar to those described before, but exhibited unusual characteristics, such as being extradural, without extension into intervertebral foramina, and being located in an atypical region (T7-T8). Moreover, survival time and relapse-free interval are greater than previously reported for similar cases.
