Application of full-balance-integrated technique in asymmetrical pedicle subtraction osteotomy for treating fixed degenerative lumbar kyphoscoliosis
Publication date: Available online 23 May 2015 Source:Formosan Journal of Surgery Author(s): Hsien-Ta Hsu , Ming-Hsueh Lee , Kuo-Feng Huang A 56-year-old female patient experienced mild back pain, which radiated to her legs, as well as intermittent claudication for 5 years. The symptoms became more pronounced on sitting and walking, and conservative therapy was ineffective in relieving pain. Preoperative whole-spine X-ray scans revealed degenerative lumbar kyphoscoliosis. Asymmetrical pedicle subtraction osteotomy was performed and a convex-sided posterolateral wedge osteotomy was applied to correct the scoliosis an...

Current status of minimally invasive thoracolumbar spine surgery for treating neoplastic, traumatic, and infectious spine diseases
Publication date: Available online 16 May 2015 Source:Formosan Journal of Surgery Author(s): Jiann-Her Lin The application of minimally invasive spine surgery (MIS) for treating thoracolumbar spine disorders and injuries has evolved rapidly, and the technical feasibility and safety of MIS has been well established. The successful use of MIS for treating degenerative spine diseases has broadened its scope, and this technique is now used for treating nondegenerative diseases. For spinal neoplastic diseases, MIS is suitable for patients with intradural extramedullary tumors limited to one or two spinal segments. However,...

EDTA-dependent pseudothrombocytopenia
In this study, two cases of EDTA-dependent PTCP are discussed to emphasize the importance of differentiating PTCP from true thrombocytopenia. The first case is of a 77-year-old woman with a femoral neck fracture, and the second case is of a 66-year-old woman with a frozen shoulder. Both cases showed low platelet counts in their routine blood tests and were ultimately proven to have PTCP. When identifying a patient with a low platelet count without any hematology disease, family history, and bleeding tendency manifestation, PTCP should also be considered. Re-examining blood samples with tubes containing other anticoagulants...

Invasive ductal carcinoma arising in borderline phyllodes tumor
Publication date: Available online 7 May 2015 Source:Formosan Journal of Surgery Author(s): Chih-Chiang Hung , Dah-Cherng Yeh , Chen-Hui Lee , Cheng-Chung Wu , Tse-Jia Liu Phyllodes tumors (PTs) are an infrequent breast tumor presentation. An invasive carcinoma arising in a borderline PT is extremely rare. A 58-year-old female presented with a mass over the left breast, which she had had for >1 year, with rapid growth in the past 3 months. The patient underwent wide excision under the assumption that the mass was a PT. Invasive ductal carcinoma and ductal carcinoma in situ arising in a borderline PT were in...

Postoperative developmental dural arteriovenous fistula
We report a case of a 39-year-old woman with a left temporal hemorrhagic lesion and an associated developmental venous anomaly. The patient underwent craniotomy and surgery for the removal of the mass. Approximately 2 months postsurgery, the patient complained of left-sided tinnitus with a bruit over the left temporal region. Cerebral angiography showed a DAVF close to the operation site. (Source: Formosan Journal of Surgery)

Unusual presentation of a low-grade intraductal papillary neoplasm of the bile duct
Publication date: Available online 31 March 2015 Source:Formosan Journal of Surgery Author(s): Kian-Hwee Chong , Chao-Chuan Wu , Chia-Chi Wang , Yi-Hsin Lee , Yao-Jen Chang , Sen-Chang Yu Intraductal papillary neoplasm of the bile duct usually manifests as abdominal pain, jaundice, and cholangitis but rarely presents as hemobilia. In this article, we present the case of a 74-year-old man with a 2-year history of repeated hemobilia without a definite diagnosis. A cholangiogram revealed a left intrahepatic duct dilatation with a filling defect, and computed tomography revealed a hyperdense lesion in the left latera...

Ankle osteoarthritis: A rare complication after free fibular flap harvesting
We report a case of rapidly progressed ankle OA after fibular flap harvesting and the experience in managing it. A 46-year-old obese woman was diagnosed to have floor of mouth cancer, T4aN1M0. After wide excision of the tumor, a 6.5 cm segmental mandibular defect was reconstructed using a free fibular osteocutaneous flap. The flap was harvested from the right leg, preserving 6.5 cm of the distal fibular bone. The patient was discharged 2 months later and could walk without assistance. Eight months after the patient was discharged, she complained of severe pain in the right ankle, especially while ambulating. Plain radiog...

Management of extremity malignant fibrous histiocytoma: A 10-year experience
Conclusion An adequate resection margin during treatment for the primary MFH tumor achieves optimal results for local disease control. It influences the OS rate, because local-recurrence-related distant metastasis is significantly associated with high mortality. (Source: Formosan Journal of Surgery)

Sciatic hernia with incarcerated urinary bladder: Laparoscopic transabdominal extraperitoneal repair with a mesh plug
Publication date: Available online 19 March 2015 Source:Formosan Journal of Surgery Author(s): Ying-Chou Chen An 87-year-old man experiencing abrupt and severe lower abdominal pain was found to have a pulsatile right hip mass. An abdominal computed tomography scan demonstrated that a portion of the redundant urinary bladder was herniating through the right sciatic foramen and into the right gluteus maximus muscle. Laparoscopic transabdominal extraperitoneal repair with a synthetic mesh plug was performed. The patient recovered uneventfully, without recurrence during 3 years of follow-up. The pathogenesis, clinical man...

Yang , Kuo-Feng Huang A 54-year-old male patient underwent an L3–4 and L4–5 microdiscectomy. Two days prior to this operation, he suffered from acute abdominal pain accompanied by nausea and vomiting. A plain upright abdominal radiograph demonstrated multiple dilated small bowel loops with air-fluid levels. Abdominal computed tomography demonstrated diffuse dilatation of the small bowel loops with collapsed colon lumen. Laparoscopic laparotomy was performed after 4 days of co...

Toxic epidermal necrolysis secondary to mycoplasma pneumoniae and herpes simplex virus infection
Publication date: Available online 11 March 2015 Source:Formosan Journal of Surgery Author(s): Ching-Hsuan Hu , Nai-Jen Chang , Shiow-Shuh Chuang , Jui-Yung Yang , Weng-Hung Chung Toxic epidermal necrolysis (TEN) is a life-threatening skin reaction associated with a high mortality rate. Most TEN is induced by drugs, but some cases are caused by other insults. Mycoplasma pneumoniae and herpes simplex virus are the most common infectious pathogens associated with TEN. In identifying the etiology of TEN, it is crucial to include not only a detailed drug history but also potential infection sources. Any suspicious inf...

Diverticulitis presenting as right incarcerated inguinal hernia
This report presents an unusual condition of diverticulitis with an abscess resulting from a perforation but having the appearance of an incarcerated inguinal hernia. The clinical features demonstrated were not due to a strangulation of the contents in the hernia, but rather resulted from a tracking of the pus from the peritoneal cavity into the hernia sac. Being in poor general condition, the patient underwent a laparoscopic repair of the sigmoid perforation and drainage of the intra-abdominal abscess. The postoperative course was uneventful and the patient was discharged 14 days after the operation. Relevant literature i...

Dermatofibrosarcoma protuberans: A 10-year experience
Conclusion A wide excision with a 3-cm margin of safety with immediate reconstruction is a reliable method for DFSP resection. Initiating adjuvant radiotherapy might reduce the chance of local recurrence. To minimize the complications of skin graft, pedicled, or free flaps provide superior functional outcome, soft-tissue augmentation, and esthetic results. (Source: Formosan Journal of Surgery)
