  • Repairing partial suprahyoid epiglottis-preserved circumferential defect in near total laryngectomy with anterior medial thigh flap in advanced laryngeal cancer

    ObjectiveTo explore the feasibility to restore pronunciation function by repairing partial suprahyoid epiglottis-preserved circumferential defect in near total laryngectomy with anterior medial thigh flap in advanced laryngeal cancer. Methods A retrospective study of 5 male patients with advanced laryngeal cancer between August 2019 and October 2022, aged 56-73 years, with an average age of 65 years were reviewed. The disease duration ranged from 3 to 24 months, with an average of 8 months. Tumor classification by location: 2 cases of glottic type, 2 cases of supraglottic type, and 1 case of subglottic type; TNM staging: 3 cases of T4N0M0 stage, 1 case of T4N1M0 stage, and 1 case of T4N2M0 stage; American Joint Committee on Cancer (AJCC) staging (2017): stage Ⅳ. Near total laryngectomy with partial suprahyoid epiglottis-preserved and selective bilateral neck dissection were performed before the anterior medial thigh flap was used to repair the circumferential defects. The flap size ranged from 6 cm×5 cm to 8 cm×6 cm. Four patients underwent adjuvant radiotherapy and chemotherapy after operation, while 1 patient did not receive any other adjuvant treatment such as radiochemotherapy. Results The flaps of all 5 patients survived without obvious neck infection. One patient developed a slight pharyngeal fistula after oral feeding at 1 month after operation, which healed after another week of gastric feeding. Primary healing also achieved in the thigh donor area. One patient had bilateral cervical lymph node metastasis, and 1 patient had lymph node metastasis on one side. The remaining 3 patients had no cervical nodes metastasis on both sides. All 5 patients were followed up 12-36 months, with an average of 27.6 months. Four patients had clear, audible, and hoarse voice while 1 patient (case 3) had pronunciation similar to whispering. Laryngoscopy showed that the reconstructed laryngeal inlet was fissure-shape and the reconstructed laryngo-trachea canal below the laryngeal inlet was gradually enlarged. At 1 month after operation, the gastric tube was withdrawn and the food was taken orally. There was no obvious aspiration pneumonia. The tracheostomy tube could be blocked in 4 patients for from 30 seconds to 3 minutes. Among them, 3 patients were able to make a noticeable pronunciation even when the tube was not blocked, and they were able to engage in barrier-free language communication; the tracheostomy tube could not be blocked in 1 patient who had a pronunciation similar to whispering. Preliminary voice analysis showed that the patients have a relaxed and natural pronunciation, without obvious breath-holding or air-swallowing movement, compared to patients with esophageal pronunciation. Decannulation did not achieved until the last follow-up in all 5 patients. ConclusionThe anterior medial thigh flap can repair circumferential defects after near total laryngectomy in advanced laryngeal cancer patients and achieve satisfactory pronunciation, thus can serve as an effective pronunciation rehabilitation method. The preserved part of epiglottis may play a role to prevent postoperative aspiration.

Methods From January 2002 to December 2009,four patients underwent total laryngopharyngectomy and free jejunal. But 8-18 months later, the patients underwent another operation because of recurrent metastatic mass in the ipsilateral neck side of anastomosis; in whom three underwent radical neck dissection and one underwent local enlarged mass resection. In the four patients, two had arteriovenous pedicles remained and another two kept only venous pedicles. Results All of the four patients experienced first-stage healing. The deglutitive function in the two patients who had received the arteriovenous pedicles preservation didn’t differ much from that before the operation. While vague anguish in the anterior region of the neck, weak peristalsis of the transplanted jejunum, a little discomfort and slow swallowing were found in another two patients. Conclusion Keeping vascular pedicles during re-operation helps make the activity of the transplanted jejunum.

Methods We retrospectively analyzed the clinical manifestations, signs, preoperative and postoperative management, and the treatment outcome of five patients with symmetric lipomatosis hospitalized in the Department of Otolaryngology-Head and Neck Surgery of West China Hospital between March 2004 and October 2010. Results All the five patients are male with a large quantity of subcutaneous fat deposit in and around the neck. Among them, one patient demonstrated extending upper thorax mass in the form of symmetrical apophysis; three experienced obstructive sleep apnea hypoventilation syndrome, and two had the symptom of snoring without apnea. Four patients had a long history of alcohol abuse with fatty liver, but had no liver dysfunction. In these four patients, one had alcoholism for many times. One out of the five patients had no history of alcohol abuse, but said to have been treated by a traditional Chinese medical technique GUASHA. All the patients underwent resection surgery, during which a large amount of noncapsulated white adipose tissue was confronted. The duration of follow-up lasted from three months to two years. There was one case of recurrence one year after the surgery and the patient refused re-operation. No obvious recurrence was found in the rest of the group. Conclusions Symmetric lipomatosis is a benign lesion characterized by diffused and symmetric accumulation of adipose tissue in the superficial or deep fascia space in the cervico-thoracic region. It mainly takes place in the middle-aged people. Long history of alcohol abuse and typical clinical manifestations can help to reach the diagnosis, but alcoholism may not be the only cause in etiology. Surgery may be the feasible therapeutic modality up to now.

  • Protection for great auricular nerve during surgery for first branchial cleft anomaly in children

    ObjectiveTo explore the feasibility to protect great auricular nerve during surgery for first branchial cleft anomaly in children.MethodsThe data of 17 cases of first branchial cleft cyst, sinus or fistula admitted to West China Hospital of Sichuan University from September 2005 to May 2015 were reviewed. The extent of lesion was demonstrated by enhanced CT before operation. Later surgery further proved that the middle ear and mastoid process was not involved in any of the cases. During surgery, some branches of great auricular nerve were dissected and spared. The cyst, sinus or fistula was obliterated completely while the whole or part of the parotid gland was preserved. The patients were followed-up from half a year to three years with mean time of 2 years and 1 month.ResultsNo recurrence or facial paralysis were found in all patients after surgery. Twelve patients had no paresthesia in the area innervated by great auricular nerve, five patients experienced numbness of ear lobe or inferior 1/3 of the auricle.ConclusionIt is feasible to protect some branches of great auricular nerve during the operation for first branchial cleft anomaly, which does not hinder the thoroughness of the resection for the lesion, and helps to improve the children’s quality of life.

  • One-stage posterior reduction single nail and rod fixation combined with the anterior operation for lower cervical fracture-dislocation combined with unilateral locked facet

    ObjectiveTo investigate the effect of one-stage posterior reduction single nail and rod fixation combined with the anterior operation on lower cervical fracture-dislocation combined with unilateral locked facet.MethodsA retrospective analysis of 28 patients with lower cervical fracture-dislocation combined with unilateral locked facet who underwent one-stage posterior-anterior approach surgery between June 2012 and March 2017 were conducted. The Cobb angle, vertebral body horizontal displacement, height of intervertebral space, recovery of nerve function and operative complications were observed before and after operation.ResultsAll patients were followed up for 12-24 months, with an average of (18.9±4.7) months. All the patients received good reposition after operation without complications such as large blood vessels, trachea, esophagus, spinal dura mater injury and so on. The incisions healed well in all patients. Postoperative complications: postoperative hoarseness and dysphagia occured in 3 cases, pharynx and larynx pain in 8 cases, pulmonary infection in 1 case, and hyponatremia in 2 cases; all patients recovered after the related symptomatic treatment. Postoperative X-ray showed that all the patients were completely corrected without residual small joint semi dislocation and kyphosis. No spinal cord or nerve injury aggravators occurred after surgery. The neurological function of all patients was improved to different degrees 12 months after operation. American Spinal Cord Injury Association (ASIA) classification showed that, of the 6 cases classified as type B preoperatively, 4 cases turned into type C and 2 cases into type D postoperatively; of the 13 cases classified as type C preoperatively, 10 cases turned into type D and 3 into type E postoperatively; and all the 8 cases classified as type D preoperatively turned into type E postoperatively. The ASIA scores increased by 1-2 levels compared with those before operation (P<0.05). The height of cervical intervertebral space, physiological curvature and cervical stability of all patients were well maintained 7 days and 12 months after operation, which were significantly improved compared with those before operation (P<0.05). There was no significant difference between the two follow-up visits at 7 days and 12 months after operation. The Japanese Orthopaedic Association score at 12 months after operation (14.6±2.3) was significantly better than that before operation (6.8±2.6), and the average improvement rate was (79.6±18.8)% (P<0.05). No complications such as screw loosening, fracture or displacement occurred during follow-up.ConclusionOne-stage posterior reduction single nail and rod fixation combined with the anterior operation is safe and effective for the treatment of lower cervical fracture-dislocation combined with unilateral locked facet.

  • Application of transverse cervical artery flap in laryngeal function preservation surgery of hypopharyngeal carcinoma

    Objective To explore the value and limitation of transverse cervical artery flap in laryngeal function preservation surgery of hypopharyngeal carcinoma. Methods Between January 2013 and December 2019, 18 male patients with hypopharyngeal carcinoma were admitted. The patients’ age ranged from 48 to 77 years, with a median age of 65 years. The disease duration ranged from 3 to 8 months (mean, 5 months). All patients were diagnosed as squamous cell carcinoma by biopsy before operation. According to the American Joint Committee on Cancer (AJCC) guidelines (2017, 8th ed), TNM staging was T2N0M0 in 9 cases, T2N1M0 in 2 cases, and T3N0M0 in 7 cases, and cTNM staging was stage Ⅱ in 9 cases and stage Ⅲ in 9 cases. The lesions of 15 cases were located in the piriform fossa of hypopharynx on one side, among which the esophageal entrance was involved in 4 cases. The lesions of 3 cases were located in the posterior wall of the hypopharynx with esophageal entrance involvement. After partial pharyngo- laryngectomy and bilateral neck lymph node dissection, the hypopharyngeal and laryngeal defects were repaired with transverse cervical artery flaps, the size of the flap ranged from 4 cm×3 cm to 6 cm×4 cm. The accompanying vein of transverse cervical artery (7 cases), external jugular vein (6 cases), and combination of both (5 cases) served as venous reflux. Retrograde external jugular venous reflux exercise was performed in 2 flaps with venous reflux obstruction during operation. The incisions at donor sites were directly sutured or via relaxed incision sutured. Radiotherapy and chemotherapy were supplemented within 3 months after operation. Tracheal cannula with air bag was used to prevent patients from aspiration in the early postoperative stage. Results The operation time was 4-6 hours, with an average of 4.5 hours. All patients were followed up 1-5 years (mean, 2 years and 6 months). Postoperative pathological examination showed that 7 cases had cervical lymph node metastases on the affected side, and there was no lymph node metastasis in cervical region Ⅴ; the remaining 11 cases had no lymph node metastasis. After operation, 16 flaps survived successfully, and 2 flaps with external jugular vein reflux were covered with white pseudomembrane, no flap necrosis was found after the pseudomembrane fell off. Four cases had no obvious accidental aspiration after operation; 14 cases had obvious accidental aspiration, of which 13 cases were significantly reduced at 3 months after operation, and 1 case still had obvious accidental aspiration at 6 months after operation, and the accidental aspiration decreased significantly after pulling out the gastric tube. All patients had no aspiration pneumonia. One case developed upper mediastinal lymph node metastasis at 1 year and 2 months after operation, and died of recurrence and pulmonary infection at 1 year and 3 months after operation. No recurrence or metastasis was found in the remaining 17 cases during follow-up. Tracheal cannula was successfully removed in 7 cases at 2-5 months after operation. Different degrees of accidental aspiration in 11 patients were confirmed by esophagography, so the tracheal cannula was retained. All patients had pronunciation function after operation. All incisions at the donor sites healed by first intention, and the shoulder joint function was normal. Conclusion Using transverse cervical artery flap to repair the hypopharyngeal and laryngeal defects during hypopharyngeal carcinoma surgery in patients without lymph node metastasis in cervical region Ⅴ, can achieve good results of laryngeal function preservation. In cases with suspected lymph node metastasis in cervical region Ⅴ or venous dysplasia of accompanying vein of transverse cervical artery, there is a risk of tumor recurrence or flap necrosis, and the repair method needs to be cautiously employed.

  • Risk prediction model for acute exacerbation of chronic obstructive pulmonary disease: a systematic review

    Objective To systematically evaluate risk prediction models for acute exacerbation of chronic obstructive pulmonary disease (COPD), and provide a reference for early clinical identification. Methods The literature on the risk prediction models of acute exacerbation of COPD published by CNKI, VIP, Cochrane, Embase and Web of Science database was searched in Chinese and English from inception to April 2022, and relevant studies were collected on the development of risk prediction models for acute exacerbations of COPD. After independent screening of the literature and extraction of information by two independent researchers, the quality of the included literature was evaluated using the PROBASTA tool. Results Five prospective studies, one retrospective case-control study and seven retrospective cohort studies were included, totally 13 papers containing 24 models. Twelve studies (92.3%) reported the area under the receiver operator characteristic curve ranging 0.66 to 0.969. Only five studies reported calibrated statistics, and three studies were internally and externally validated. The overall applicability of 13 studies was good, but there was a high risk of bias, mainly in the area of analysis. Conclusions The existing predictive risk models for acute exacerbations of COPD are unsatisfactory, with wide variation in model performance, inappropriate and incomplete inclusion of predictors, and a need for better ways to develop and validate high-quality predictive models. Future research should refine the study design and study report, and continue to update and validate existing models. Secondly medical staff should develop and implement risk stratification strategies for acute exacerbations of COPD based on predicted risk classification results in order to reduce the frequency of acute exacerbations and to facilitate the rational allocation of medical resources.

  • Analysis of antimicrobial resistance in clinical isolates in a general teaching hospital in 2019

    ObjectiveTo investigate the distribution and antimicrobial resistance of the clinical strains isolated from the First Affiliated Hospital of Xi’an Jiaotong University in 2019 and provide a basis for clinical rational use of antibiotics.MethodsAll the clinical samples which were collected from January 1st to December 31st in 2019 were employed to determine antimicrobial resistance retrospectively. Results were interpreted according to Clinical and Laboratory Standards Institute 2019 breakpoints and analyzed by WHONET 5.6 software.ResultsA total of 6 784 nonduplicate strains were isolated in 2019, including 2 865 (42.2%) strains of Gram-positive bacteria and 3 919 (57.8%) strains of Gram-negative bacteria. The top five pathogens with the highest detection rate were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, Pseudomonas aeruginosa, and Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus and methicillin-resistant coagulase negative Staphylococcus accounted for 33.0% and 72.0%, respectively. The detection rate of vancomycin-resistant Enterococcus faecium was 1.0% and the detection rates of linezolid-resistant Enterococcus faecium and Enterococcus faecalis were 0.3% and 2.9%, respectively. As for the non-meningitis Streptococcus pneumoniae, the prevalence of penicillin-susceptible Streptococcus pneumoniae was 100% in the isolates from adults. Extended-spectrum β-lactamases-producing strains accounted for 58.2%, 33.6%, and 33.3% in Escherichia coli, Klebsiella spp., and Proteus mirabilis, respectively. The total detection rate of carbapenem-resistant Enterobacteriaceae was 7.8%, among which the detection rates of carbapenem-resistant Escherichia coli and carbapenem-resistant Klebsiella pneumoniae were 1.5% and 17.2%, respectively. The percentages of Pseudomonas aeruginosa strains resistant to imipenem and meropenem were 25.0% and 21.6%, respectively, and those of Acinetobacter baumannii were 73.8% and 74.2%, respectively.ConclusionsBacterial resistance is still serious in this hospital. It is necessary to strengthen rational drug use. At the same time, effective prevention and control measures should be taken to avoid cross-infection.
