Efficacy of routine exposure versus neuromonitoring of superior laryngeal nerve in thyroid cancer surgery / 中国基层医药

Objective:To investigate the efficacy of routine exposure versus neuromonitoring of the external branch of the superior laryngeal nerve (EBSLN) in thyroid cancer surgery. Methods:The clinical data of 500 patients who underwent open thyroid cancer surgery in the Department of Breast and Thyroid Surgery, People's Hospital of Quzhou from July 2017 to June 2020 were retrospectively analyzed. These patients were divided into a monitoring group ( n = 300) and an unmonitored group (control group) ( n = 200) according to whether neuromonitoring was performed during surgery. In the control group, the EBSLN was routinely exposed during the surgery for naked observation. In the monitoring group, the EBSLN was monitored. The Voice Handicap Index score, vocal cord function, and serum levels of parathyroid hormone and calcium ion were compared between the two groups before and after surgery. All patients were followed up for 1 year to observe injury to the EBSLN, parathyroid gland injury, and hypocalcemia. Results:In the monitoring group, operative time (112.32 ± 10.42) minutes, intraoperative blood loss (10.58 ± 5.04) mL, time to extubation (2.07 ± 0.54) days, postoperative drainage flow (10.55 ± 3.58) mL, and postoperative hospital stay (3.03 ± 1.03) days were significantly shorter and less compared with the control group ( t = 18.68, 15.09, 15.24, 32.98, 27.37, all P < 0.001). Compared with before surgery, normalized noise energy, amplitude perturbation, fundamental frequency perturbation, and fundamental frequency value in each group were significantly decreased after surgery, harmonic to noise ratio and the Voice Handicap Index were significantly increased after surgery. These indices were more obviously improved in the monitoring group compared with the control group ( t = 43.31, 27.10, 46.45, 37.11, 8.97, all P < 0.001). Compared with before surgery, serum levels of parathyroid hormone and calcium ion in each group were significantly decreased after surgery. After surgery, serum levels of parathyroid hormone and calcium ion in the control group were significantly lower than those in the monitoring group ( t = 41.14, 5.99, both P < 0.001). The incidence of complications in the monitoring group [4 cases of hypocalcemia (1.33%), 0 cases of parathyroid injury (0.00%), 8 cases of injury to the EBSLN] was significantly lower than that in the control group ( χ2 = 73.41, 74.17, 76.29, all P < 0.001). Conclusion:Neuromonitoring of the EBSLN during open thyroid cancer surgery can effectively improve patient voice and vocal cord function, reduce the rate of injury to the EBSLN, and has a clinical application value.

Suffering of patients developing lymphedema following gynecological cancer surgery / Journal of Rural Medicine

Objective: Lymphedema developing in the lower extremities following gynecological cancer surgery (LE-GCS) produces various kinds of sufferings, including impacts on quality of life (QOL) and body image. This research will serve as a basic resource for the care of patients with this type of lymphedema (LE).Patients and Methods: A qualitative discursive research method: Thirteen patients suffering from LE-GCS were interviewed in a semi-organized manner. Analysis involved extracting and codifying from transcripts and expressions related to the suffering of LE. Next, these codes were arranged into categories and subcategories under the supervision of qualitative researchers. Furthermore, this study was conducted with the approval of the Research Ethics Review Specialist Committee, which targets individuals affiliated with the public university corporation of Shiga Prefectural University.Results: Based on the interviews with 13 patients aged 47–79 (median age 62), two core categories were created: 1). Suffering of LE Developing in Lower Extremities (570 codes, seven categories, 23 subcategories); and 2). Supports that Allow Patients to Face Suffering of LE (254 codes, four categories, 14 subcategories).Conclusion: Patients with LE-GCS live with the fear that LE exacerbation will produce adverse life changes, and this may exceed the fear of cancer itself. The aggravation of their condition results in immense pain as well as reduced mobility, change in appearance, and loss of self-worth. The symptoms fluctuate, and may lead to chronic misery, which does not manifest, but occasionally flares-up because of both, worsening physical disability as well as ordinary events. Additionally, every patient subjectively described the strength they found within themselves to face the suffering. They cited the support of family and friends, existence of compassionate therapists and doctors, acquisition of knowledge, and self-care.

Lung ultrasonography as a tool to guide perioperative atelectasis treatment bundle in head and neck cancer patients undergoing free flap reconstructive surgeries: a preliminary observational study / Ultrassonografia pulmonar como ferramenta para orientar o tratamento perioperatório de atelectasia em pacientes com câncer de cabeça e pescoço submetidos a cirurgia reconstrutiva com retalho livre: um estudo observacional preliminar

Abstract Introduction: General anesthesia causes pulmonary atelectasis within few minutes of induction. This can have significant impact on postoperative outcome of cancer patients undergoing prolonged reconstructive surgeries. Objective: The purpose of this study was to evaluate the impact of sonographically detected perioperative atelectasis on the need for postoperative oxygen supplementation, bronchodilator therapy and assisted chest physiotherapy in patients undergoing free flap surgeries for head and neck carcinoma. Methods: Twenty eight head and neck cancer patients underwent bilateral pulmonary ultrasonographic assessments before and after lung surgery. Lung ultrasound scores, serum lactate, and PaO2/FiO2 ratio were measured both at the beginning and at end of the surgery. Patients were scanned in the supine position and the number of single and confluent B lines was noted. These values were correlated with the need for oxygen therapy, requirement of bronchodilators and total weaning time to predict the postoperative outcome. Other factors affecting weaning were also studied. Results: Among twenty eight patients, seven had mean lung ultrasound score of ≥10.5 which correlated with prolonged weaning time (144.56±33.5min vs. 66.7±15.7min; p = 0.005). The change in lung ultrasound score significantly correlated with change in PaO2/FiO2 ratio (r = −0.56, p = 0.03). Elevated total leukocyte count >8200 ΜL and serum lactate >2.1 mmoL/L also predicted prolonged postoperative mechanical ventilation. Conclusion: This preliminary study detected significant levels of perioperative atelectasis using point of care lung ultrasonography in head and neck cancer patients undergoing long duration surgical reconstructions. Higher lung ultrasound scores highlighted the need for frequent bronchodilator nebulizations as well as assisted chest physiotherapy and were associated with delayed weaning. We propose more frequent point of care lung ultrasonographic evaluations and use of recruitment maneuvers to reduce the impact of perioperative pulmonary atelectasis.

Resumo Introdução: A anestesia geral causa atelectasia pulmonar poucos minutos após sua indução. Isso pode ter um impacto significativo no resultado pós-operatório de pacientes com câncer submetidos a cirurgias reconstrutivas prolongadas. Objetivo: Avaliar o impacto das atelectasias perioperatórias detectadas por ultrassonografia na necessidade de suplementação pós-operatória de oxigênio, terapia broncodilatadora e fisioterapia respiratória assistida em pacientes com carcinoma de cabeça e pescoço submetidos a cirurgias com uso de retalho livre. Método: Foram submetidos a avaliações ultrassonográficas pulmonares bilaterais antes e após a cirurgia 28 pacientes com câncer de cabeça e pescoço. Os escores de ultrassonografia pulmonar, lactato sérico, razão PaO2/FiO2 foram medidos no início e no fim da cirurgia. Os pacientes foram avaliados na posição supina e o número de linhas B confluentes e únicas foi observado. Esses valores foram correlacionados com a necessidade de oxigenoterapia, necessidade de broncodilatadores e tempo total de desmame para predizer o resultado pós-operatório. Outros fatores que afetam o desmame também foram estudados. Resultados: Entre os 28 pacientes, sete apresentaram escore médio de ultrassonografia pulmonar ≥ 10,5, que se correlacionou com o tempo de desmame prolongado (144,56 ± 33,5 minutos vs. 66,7 ± 15,7 minutos; p = 0,005). A mudança no escore de ultrassonografia pulmonar correlacionou-se significantemente com a mudança na razão PaO2/FiO2 (r = −0,56, p = 0,03). A contagem total elevada de leucócitos > 8200 uLe o nível de lactato sérico >2,1 mmoL/L também previram ventilação mecânica pós-operatória prolongada. Conclusão: Este estudo preliminar detectou um nível significante de atelectasia perioperatória com ultrassonografia pulmonar no local de atendimento em pacientes com câncer de cabeça e pescoço submetidos a reconstruções cirúrgicas de longa duração. Escores mais altos de ultrassonografia pulmonar enfatizaram a necessidade de nebulizações broncodilatadoras frequentes e fisioterapia respiratória assistida e foram associados a desmame tardio. Propomos avaliações ultrassonográficas pulmonares mais frequentes no local de atendimento e o uso de manobras de recrutamento para reduzir o impacto das atelectasias pulmonares perioperatórias.

Bibliometrics and visualization analysis of esophageal cancer surgery-related researches / 中国胸心血管外科临床杂志

@#Objective     To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods     The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results     Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion     Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.

Introduction: Transanal total mesorectal excision (TaTME) has revolutionized the surgical techniques for lower-third rectal cancer. The aim of the present study was to analyze the outcomes of quality indicators of TaTME for rectal cancer compared with laparoscopic TME (LaTME). Methods: A cohort prospective study with 50 (14 female and 36male) patients, with a mean age of 67 (range: 55.75 to 75.25) years, who underwent surgery for rectal cancer. In total, 20 patients underwent TaTME, and 30, LaTME. Every TaTME procedure was performed by experienced colorectal surgeons. The sample was divided into two groups (TaTME and LaTME), and the quality indicators of the surgery for rectal cancer were analyzed. Results: There were no statistically significant differences regarding the patients and the main characteristics of the tumor (age, gender, American Society of Anesthesiologists [ASA] score, body mass index [BMI], tumoral stage, neoadjuvant therapy, and distance from the tumor to the external anal margin) between the two groups. The rates of: postoperativemorbidity (TaTME: 35%; LaTME: 30%; p=0.763);mortality (0%); anastomotic leak (TaTME: 10%; LaTME: 13%; p=0.722); wound infection (TaTME: 0%; LaTME: 3.3%; p=0.409); reoperation (TaTME: 5%; LaTME: 6.6%; p=0.808); and readmission (TaTME: 5%; LaTME: 0%; p=0.400), as well as the length of the hospital stay (TaTME: 13.5 days; LaTME: 11 days; p=0.538), were similar in both groups. There were no statistically significant differences in the rates of positive circumferential resection margin (TaTME: 5%; LaTME: 3.3%; p=0.989) and positive distal resection margin (TaTME: 0%; LaTME: 3.3%; p=0.400), the completeness of the TME (TaTME: 100%; LaTME: 100%), and the number of lymph nodes harvested (TaTME: 15; LaTME: 15.5; p=0.882) between two groups. Conclusion: Transanal total mesorectal excision is a safe and feasible surgical procedure for middle/lower-third rectal cancer. (AU)

Analysis of the incidence of early enteral nutrition intolerance and related influencing factors in postoperative gastric cancer patients / 中华临床营养杂志

Objective:To investigate the incidence of early enteral nutrition intolerance and related influencing factors in postoperative gastric cancer patients.Methods:90 gastric cancer patients who underwent radical gastric cancer surgery and received early enteral nutrition thereafter in our hospital were retrospectively enrolled from January 2019 to December 2020. Patients were divided into early enteral nutrition tolerance group ( n=30) and intolerance group ( n=60) according to whether they developed nausea, vomiting, abdominal distension, abdominal pain, diarrhea and other symptoms after early enteral nutrition. The general characteristics of the two groups were compared and the risk factors of early enteral nutrition intolerance in postoperative gastric cancer patients were analyzed using multivariate Logistic regression. Results:60 (66.67%) of the 90 postoperative gastric cancer patients experienced early enteral nutrition intolerance. Multivariate Logistic regression analysis showed that ≤4 hours of out-of-bed activity on the first postoperative day and nonuse of nutrition pump were independent risk factors for early enteral nutrition intolerance in these patients ( OR=2.998; 4.586, P<0.05). Conclusions:The risk factors of early enteral nutrition intolerance in postoperative gastric cancer patients were ≤4 hours of out-of-bed activity on the first postoperative day and nonuse of nutrition pump. Corresponding clinical interventions could be implemented to prevent the occurrence of early enteral nutrition intolerance in postoperative gastric cancer patients.

The 2005 National Cancer Care Policy brought important changes, including the creation of codes in the SIGTAP table for different surgical specialties. The Pressman and Wildavsky's Public Policy Implementation Theory was used to explain the implementation model of this policy. This study innovates by presenting a systematic review of the SIGTAP table codes in force, used by H&N surgeons, showing the discrepancy between what is proposed, the reality in the execution of procedures, and the gap in the amounts paid for medical fees and the values allocated for hospital services. Objective: To demonstrate that the SUS-SIGTAP table, with regard to surgical procedures performed by H&N surgeons, is not in accordance with reality both in terms of effectiveness and values allocated. Methods: Bibliographic, documentary and legislation search were conducted between 2005 and 2019. Results: The SIGTAP table is not in accordance with the execution of procedures and presents a gap regarding the amounts paid. Conclusion: The codes need to be readjusted to meet reality in several variables, such as the ICD, description, purpose, values allocated, and new technologies.

Simultaneous thoracoscopic approach in a patient with long-standing persistent atrial fibrillation and primary lung cancer: the first described case

Abstract Cardiac rhythm disorders are common in many patients with cancer. The management of synchronous long-standing persistent atrial fibrillation and pulmonary lesions remains a serious surgical dilemma due to the lack of clinical data and surgical guidelines. To the best of our knowledge, this is the first described case of simultaneous thoracoscopic pulmonary segmentectomy and left atrial posterior wall and pulmonary vein isolation combined with left atrial appendage resection in a patient with early-stage primary lung cancer and long-standing persistent atrial fibrillation.

Assessment of preoperative endometrial histopathological sampling as a predictor of final surgical pathology in endometrial cancer / Avaliação do diagnóstico histopatológico endometrial pré-operatório como preditor do diagnostico patológico final em câncer de endométrio

Abstract Objective To evaluate the agreement between the histopathological diagnoses of preoperative endometrial samples and surgical specimens and correlate the agreement between the diagnoses with the impact on surgical management and the survival of patients with endometrial adenocarcinomas. Methods Sixty-two patients treated for endometrial cancer at a university hospital from 2002 to 2011 were retrospectively evaluated. The histopathological findings of preoperative endometrial samples and of surgical specimens were analyzed. The patients were subjected to hysterectomy as well as adjuvant treatment, if necessary, and clinical follow-up, according to the institutional protocol. Lesions were classified as endometrioid tumor (type 1) grades 1, 2, or 3 or non-endometrioid carcinoma (type 2). Results The agreement between the histopathological diagnoses based on preoperative endometrial samples and surgical specimens was fair (Kappa: 0.40; p < 0.001). However, the agreement was very significant for tumor type and grade, in which a higher concordance occurred at a higher grade. The percentage of patients with lymph nodes affected was 19.2%;. Although most patients presenting with disease remission or cure were in the early stages (90.5%;), there were no significant differences between those patients who had a misdiagnosis (11/16; 68.8%;) and those who had a correct diagnosis (25/33; 75.8%;) based on preoperative endometrial sampling (p = 0.605). Conclusion Our findings corroborate the literature and confirm the under staging of preoperative endometrial samples based on histopathological assessment, especially for lower grade endometrial tumors. We suggest that the preoperative diagnosis should be complemented with other methods to better plan the surgical management strategy.

Resumo Objetivo Avaliar a concordância entre os diagnósticos histopatológicos de amostras endometriais pré-operatórias e cirúrgicas de pacientes com adenocarcinomas endometriais e avaliar o impacto da concordância entre os diagnósticos no planejamento cirúrgico e sobrevida das pacientes. Métodos Dados de 62 pacientes com câncer de endométrio operadas entre 2002 a 2011 em um hospital universitário foram avaliadas retrospectivamente. As pacientes foram submetidas à histerectomia e tratamento adjuvante, se necessário, e acompanhadas clinicamente de acordo com o protocolo institucional. Foram avaliados os resultados das análises histopatológicas das amostras endometriais pré-operatórias e cirúrgicas. As lesões foram classificadas como tumor endometrioide (tipo 1) graus 1, 2 ou 3 ou carcinoma não endometrioide (tipo 2). Resultados De modo geral, houve uma concordância baixa entre os diagnósticos histopatológicos das amostras endometriais pré-operatórias e cirúrgicas (Kappa: 0,40; p < 0,001). Entretanto, uma alta concordância entre os diagnósticos foi observada nos tumores de graus mais elevados. Comprometimento de linfonodos ocorreu em 19,2%; das pacientes e a maioria das que apresentaram remissão ou cura foram diagnosticadas nos estágios iniciais da doença (90,5%;). Não houve diferença significativa na taxa de remissão ou cura entre as pacientes que tiveram concordância (25/33; 75,8%;) ou divergência (11/16; 68,8%;) entre os resultados histopatológicos pré-operatórios e cirúrgicos (p = 0,605). Conclusão Nossos achados corroboram a literatura e confirmam o sub-estadiamento de amostras endometriais pré-operatórias com base na avaliação histopatológica, especialmente para tumores endometriais de baixo grau. Outros métodos complementares são necessários para um diagnóstico pré-operatório mais preciso a fim de melhorar o planejamento cirúrgico.
