ABSTRACT
Objective:To analyze the perioperative clinical characteristics of patients with oral cancer underwent radical resection and flap reconstrution and the nursing managements.Methods:From January 2020 to December 2020, 658 patients with oral cancer underwent radical resection and flap reconstrution in the Department of Oral and Maxillofacial Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University were retrospectively analyzed. All patients were divided into the elderly group (≥60 years) and the younger group (< 60 years), including 279 cases in the elderly group and 379 cases in the younger group. The perioperative clinical data of the patients were collected, and the perioperative general situation, postoperative complications and influencing factors of complications were analyzed.Results:There were differences between the two groups in the aspects of sex ( χ2 = 12.38, P<0.001), preoperative BMI ( t = 2.43, P = 0.015), smoking history ( χ2 = 18.34, P<0.001), preoperative anesthesia grade ( χ2 = 25.61, P = 0.001), preoperative coexisting disease ( χ2 = 46.97, P<0.001), whether oral floor or tongue cancer ( χ2 = 16.68, P<0.001), whether free flap ( χ2 = 6.81, P = 0.003), operation time ( t = 2.19, P = 0.029), preoperative test index hemoglobin ( t = 4.96, P<0.001), albumin ( t = 5.44, P<0.001), D-dimer( Z = -13.52, P<0.001), calcium levels ( t = 4.07, P<0.001) and postoperative complications ( χ2 = 14.55, P<0.001). Multivariate analysis of postoperative complications showed that the age ( OR = 1.021, 95% CI = 1.005-1.037, P = 0.011), preoperative D-dimer ( OR = 1.219, 95% CI = 1.026-1.447, P = 0.024) and the preoperative coexisting disease ( OR = 1.642, 95% CI = 1.108-2.432, P = 0.013) were the risk factors for the postoperative complications. Multivariate analysis of discharge with tube showed that the age ( OR = 1.017, 95% CI = 1.003-1.031, P = 0.017), preoperative BMI ( OR = 0.917, 95% CI = 0.873-0.963, P = 0.001), whether oral floor or tongue cancer ( OR = 2.135, 95% CI = 1.475-3.091, P<0.001), and operation time ( OR = 1.220, 95% CI = 1.120-1.328, P<0.001) were the related factors for the discharge with tube. Conclusion:In view of the above risk factors, it is beneficial for the physical and mental recovery of patients to pay attention to preoperative evaluation, make adequate preoperative preparation, postoperative nursing and observation, improve swallowing function training, prepare for discharge, pay attention to continuous nursing, and establish a tertiary hospital-community-family rehabilitation system.
ABSTRACT
OBJECTIVE To assess the treatment reliability of covered stent for carotid artery blowout after head and neck tumors resection. METHODS Five cases with postoperative rupture of carotid artery invaded by the head and neck tumor were reviewed. They presented with life threatening massive neck or oral bleedings. All of them were treated with self expanding covered stents through intervention therapy approach. RESULTS The covered stent were successfully deployed in the target arteries in all cases,the instant isolation effect was quite satisfactory. After treatment, angiography showed successful occlusion of the pseudoaneurysm, patency of carotid artery lumen, and significant improvement of clinical symptoms without neurologic dysfunction. Following up 2 to 36 months, 3 patients were alive with no disease, two patients died of recurrence. CONCLUSION For the treatment of carotid blowout, endovascular occlusion with covered stent is a minimally-invasive, safe and reliable methods.
ABSTRACT
Objective To assess the reliability and useness of using a coupling device for end-to-end venous anastomosis in patients undergoing free-tissue transfer in head and neck reconstruction.Methods Twelve patients undergoing surgical resection and head and neck defects were repaired with fibular flap,anterolateral thigh flap and radial forearm flap.The microvascular anastomotic device was used to perform venous anastomosis in these cases.Flap survival and thrombosis of the venous anastomoses were determined.Results There were no flap losses due to venous thrombosis in this series.The venous anastomosis was usually coupled in about 5.3 minutes and appear as an obviously time savings compared with performing a hand-sewn venous anastomosis.Conclusion The microvascular coupler is excellent in end-to-end venous anastomosis and certainly less taxing on the surgeon when compared with standard suture techniques.
ABSTRACT
Objective To introduce the application and assess the outcome of ProPlan CMF software in virtual surgery of mandibular resection and reconstruction with vascularized fibular graft.Methods Nineteen patients were performed mandibular resection,and immediate reconstruction with free fibular graft by application of ProPlan CMF software between March 1,2013 and January 31,2014,including 7 cases of osteoradionecrosis,6 cases of adamantoblastoma,4 cases of carcinoma of gingiva,2 cases of intra-osseous carcinoma of mandible.There were 12 males and 7 females,with an age range of 21-73 years (median,54 years).In each case,three-dimensional spiral CT scan of mandible and fibula was obtained before operation.The CT data were imported into the ProPlan CMF software and the virtual surgical planning was performed.After that,the mandibular rapid prototyping and surgical guide plates were made according to customized design.The segmental resection of mandible,titanium plate bending,fibular molding,insetting and fixing were then carried out by using these surgical guide plates.Results Operations were undertaken successfully according to preoperative design in all nineteen patients and negative margin was detected by intraoperative frozen section.The fibula was cut,shaped and fixed accurately.The operations took 4.5-7.0 hours (mean,5.5 hours).Primary healing of incision was obtained without complications except fistula in 2 cases of osteoradionecrosis,which were resolved with local wound care after 4 weeks.19 patients were followed up between 3 months to 1 year and all patients were alive with disease free.All patients were satisfactory with their maxillofacial appearance,occlusion and function.The ranges of mouth opening was 2.0-4.0 cm.The postoperative panoramic radiographs or CT scan showed perfect situation and contour of fibular graft.Healing of the donor site occurred without significant complications.All patients started early postoperative ambulation,and walked normally after 2 or 3 months.Conclusion The application of ProPlan CMF software in virtual surgical design and guide plates creation can simplify the operation,and improve the accuracy of mandibular resection and reconstruction,especially the spatial relationship of the mandible and the fibula graft.It is worth promotion widely in clinical practice.
ABSTRACT
Ezrin is an important membrane-cytoskeleton linker protein.It is highly related with tumor invasion and metastasis and indicates poor prognosis.It is reported that aberrant Ezrin expressed in many carcinomas,such as osteosarcoma and breast carcinoma.However,the complex mechanisms of Ezrin in tumor invasion and metastasis remain unclear.It is involved in several different tumor associated signal pathway based on different tumor types,including adhesion molecule signal transduction,Rho and Akt signal transduction.Therefore,research on the signal transduction of Ezrin has great significance for the understanding of cancer progression and Ezrin is probable to be a new treatment target.
