Extrahepatic disease due to hydatid cyst may develop in the abdominal and pelvic cavity, aside from in other less common locations, which may make both diagnosis and treatment more complex. We present a rare case of extrahepatic echinococcosis in a 70-year old patient with a 4-d history of dull abdominal pain, anemia within the transfusion range and fever. She underwent surgery for left renal hydatid cysts 30 years ago. After non operative treatment, imaging studies showed a calcified hydatid cyst in a retrogastric location communicating with a proximal jejunal loop. En-block resection of the mass together with the adrenal gland was performed including closure of the enteric fistula. Anatomic pathology confirmed the diagnosis of a calcified hydatid cyst of left adrenal origin. Surgery is the treatment of choice and most authors recommend removal of cyst and adrenal gland.展开更多

METHODS Eight patients with carcinoma of the maxillary sinus underwent a modified midfacial degloving operation. The tumors were classified according to the 2002 AJCC system. The TNM staging of the cases was as follows: 1 T4aN0M0, 2 T3N0M0 and 5 T2N0M0. Of the 8 cases, 1 patient underwent extended maxillectomy; exenteration of the orbit; tumorectomy of the sphenomaxillary and infratemporal fossae. Two patients received a total maxillectomy, and 5 a partial resection of the maxilla. Postoperative pathological report: 4 well-differentiated squamous carcinoma, 2 moderately-differentiated squamous carcinoma, 1 mucoepidermoid carcinoma and 1 adenoid cystic carcinoma.RESULTS A modified midfacial degloving operation can sufficiently expose a field of operation, resect the tumor within a safe margin, and leave no facial cicatricles. One patient died of intracranial metastasis 8 months after operation. We observed no recurrences or metastasis in other patients during the period of follow-up.CONCLUSION The major advantages of employing the modified midfacial degloving in maxillectomy is that a facial incision can be avoided. It has an advantage of minimal invasive surgery展开更多

Methods: Six patients with large skin and soft tissue defects were included in this report. There were 5 trauma patients and the rest one needed to receive plastic surgery for his extremity scar. All wounds were in the upper extremity. The sizes of defects ranged from 15 cmx6 cm to 30 cmx 18 cm. Pedicled latissimus dorsi myocutaneous flaps were designed according to the defect area and raised with part of latissi- mus dorsi. The thoracodorsal artery and its perforators were carefully protected during surgery. Results: All flaps healed primarily without flap congestion, margin necrosis or infection. The skin donor sites either received split-thickness skin graft (3 cases, mostly from the anterior thigh) or was closed primarily (3 cases) and had minimal morbidity. Follow-up of 6-12 months showed that the contour of flap was aesthetic and the func- tion of limb was excellent. Conclusion: Our experience indicates that the pedicled latissimus dorsi myocutaneous flap is favorable for recon- struction of large skin and soft tissue defects in the upper extremity展开更多
