To evaluate the clinical impact of preoperative serum CEA and CA19-9 on resectable gastric cancer (GC), a total of 1,075 consecutive cases with gastric adenocarcinoma were obtained retrospectively from January 2012 and December 2013 in a single tertiary hospital, and the relationships between serum CEA, CA19-9 and clinicopathologic features were investigated. Positive preoperative serum rates of CEA and CA19-9 were 22.4% and 12.3% respectively, levels significantly correlating with each other and depth of invasion, lymph node involvement, pTNM and stage. The CEA level also presented a remarkable association with lymphovascular invasion. Both CEA and CA19-9 positivity significantly and positively correlated with depth of invasion, nodal involvement, pTNM stage, lymphovascular invasion, tumor size and tumor location. Stratified analyses according to gender or tumor location showed preoperative CEA or CA19-9 had different associations with clinicopathologic features in different gender subgroups or location subgroups. Preoperative serum CA19-9 positivity may be more meaningful for tumor size rather than CEA. In conclusion, preoperative serum CEA and CA19-9 correlate with disease progression of GC, and may have applications in aiding more accurate estimation of tumor stage, decision of treatment choice and prognosis evaluation.

Purpose: Autologous breast reconstruction with abdominal tissue is one of the best options after mastectomy. In a free transverse rectus abdominis myocutaneous(TRAM) or deep inferior epigastric artery perforator(DIEP) flap, a preoperative evaluation of the precise location of perforating vessels and vascular run - off systems is required. The objective of this report is to demonstrate the usefulness of multidetector computed tomography(MDCT) in the preoperative planning of patients undergoing breast reconstruction with abdominal flap. Methods: From June 2006 to January 2008, 28 patients underwent MDCT evaluation before breast reconstruction. All subjects were females with an age range of 30 to 55 years. The CT scan was performed using a 64 - slice MDCT scanner(Brilliance 64; Philips Medical Systems, Best, Netherlands). Results: One perforator or two major perforators were marked on image in good relation with a hand - held Doppler examination and intraoperative findings. All vascular run - off systems were cleared before operation. Conclusion: Preoperative evaluation of perforator arteries with MDCT angiography is beneficial in patients undergoing breast reconstruction. This technique provides a noninvasive approach of the vascular anatomy of the entire anterior abdominal wall.

The purpose of this study was to aid in the evaluation of prognosis of temporomandibular joint following orthognathic surgery. For this study, 20 patients (40 TMJ) who undergone orthognathic surgery were examined. Preoperative and postoperative tomograms of TMJ were taken. And the subjects were divided into 3 groups according to postoperative periods. The obtained results were as follows; 1. There were no significant differences between preoperative and postoperative changes in joint spaces in each group and between groups(P<0.05). 2. There were no significant differences between preoperative and postoperative ratio of joint space(P<0.05). 3. There were no significant differences between preoperative and postoperative changes in the range of motion of condylar head(P<0.05). 4. The bony changes of condylar head were observed in 14(35%) condyles (6 erosion, 2 flattening, 5 double contour, 1 osteophyte).

Purpose: The purpose of this study was to evaluate preoperative nutritional status in elderly patients with orthopedic surgery and identify related factors for malnutrition risk. Methods: This study enrolled 337 patient's medical record who underwent orthopedic surgery in hospital between January and December 2015. Data was collected retrospectively. Nutritional status was evaluated by using the Nutritional Risk Screening 2002. Multivariable logistic regression analysis was used to identify independent related factors for malnutrition risk. Results: Malnutrition risk developed in 58 patients (17.2%). Logistic regression analysis identified low physical activity, visual impairment, depression, sleep disorder, low serum calcium level, and low serum albumin level as related factors. Conclusion: Orthopedic surgery in elderly patients was associated with high risk of preoperative malnutrition. The results of this study suggest that evaluating the nutritional status and related factors should be done with preoperative status of elderly patients. At the same time, interventions for nutritional care should be adjusted to meet the nutritional needs of individuals and decrease the risk of malnutrition.

In this investigation we undertook to evaluate the utility of radionuclide cardiac angiography in the detection of cardiac shunts before and after surgical correction. Time-activity curves of ventricles and lungs were evaluated after bolus intravenous injection of 99mTc-human serum albumin in 512 preoperative patients and 551 post-operative patients. Omitting 31 cases of technical failure due to poor bolus, we detected shunts in 459 cases of 481 preoperative evaluations, so the detectability was 95.4%. The cases which couldn`t be detected by this method had small amount of shunt. Also the degree of shunt detected by radioisotope methods were well correlated with oxymetry method. [r=0.89, p<0.01 ] In postoperative evaluations, 18 out of 411 patients with left to right shunt and 10 out of 140 right to left shunt were found to have remnant shunts with radionuclide cardiac angiography. Of the 28 cases with failed operation, 2 were confirmed in reoperation, 2 by cardiac catheterization, 2 by two -dimensional echocardiography. All except one .f these patients had membranous ventricular septal defects and those with left to right shunts had moderate to severe pulmonary hypertension and shunt amount. Also those had larger septal defects than control group. We consider that radionuclide cardiac angiography is a simple and noninvasive method which can show the preoperative diagnosis and postoperative follow up of cardiac shunts.

The surgical removal of solid deep-seated hemangioblastomas remains challenging, because treatment of these lesions is often complicated by severe bleeding associated with the rich vascularity of this tumor, and by severe neural tissue injury associated with the difficulty of en bloc resection, especially when the tumor is located at the cervicomedullary junction. Therefore, preoperative embolization of deep-seated solid hemangioblastomas may play an important role in successful surgical removal by reducing major bleeding and neural tissue damage. A 24-year-old woman, 28-weeks pregnant, was admitted to our hospital for the evaluation of quadriparesis, and brain magnetic resonance imaging[MRI] revealed intra-axial mass lesion in the cervicomedullary junction. After delivery, her neurologic symptoms became aggravated, and we decided to operate. Preoperative angiography revealed a hypervascular tumor in the posterior fossa, and embolization of the main feeding artery using gelfoam and microcoil, resulted in marked reduction of tumor vascularity. She underwent a midline suboccipital craniotomy involving the removal of the arch of C-1. The tumor was totally removed through a midline myelotomy, and at her 6-month follow-up she walked independently. We report on the combined use of the preoperative embolization of feeding vessels and subsequent operative resection in a patient with a solid hemangioblastoma at the cervicomedullary junction immediately after delivery.

Purpose: To investigate early complications after repair of massive rotator cuff tears and to find out factors that compromise the results. Materials and Methods: Fourteen patients who had two or more cuff tendons involved were included. All patients were operated by open acromioplasty and rotator cuff repair. At 3 months after operation, we investigated whether there were any early complications or not. We used ASES scoring system for preoperative and follow up evaluation. In addition, various preoperative factors, such as duration of symptom, degree of tendon retraction, degree of fatty degeneration, and acromio-humeral distance, were compared between the complicated patients and non-complicated patients. Results: At 3 months after operation, the ASES score and pain were improved in any degree in all patients. But 5 patients complained persisting pain, and three of them showed major complications such as re-rupture of rotator cuff or deltoid rupture. But no preoperative factors in complicated patients were significantly different from those in non-complicated patients. Conclusion: None of the preoperative factors were related to the complications. There was a tendency of overestimation of fatty degeneration in MRI. Some factors in surgical technique and rehabilitation were highly suspected to be related to the complications.
