Objective To investigate the clinical outcomes of subxiphoid video-assisted thoracoscopic thymectomy for myasthenia gravis. Methods The clinical data of the 85 patients undergoing video-assisted thoracoscopic thymectomy for myasthenia gravis in Department of Cardiothoracic Surgery, Huashan Hospital affiliated to Fudan University between January 2014 and July 2016 were studied. Subxiphoid approach video-assisted thoracoscopic thymectomy (SXVT) and through traditional unilateral approach video-assisted thymectomy (TVAT) were compared. The clinical outcomes of SXVT and TVAT were compared. Results There was no surgical death and no statistical difference between the two groups in drainage time, postoperative volume of drainage, postoperative hospital stay and bleeding volume during operation (P>0.05). However, the acute chest pain after surgery, as well as the postoperative chest pain, and operative time were less in the the SXVT group than that in the TVAT group (P<0.05). Conclusion SXVT for myasthenia gravis is safe and executable. It can alleviate intercostal neuralgia and abnormal chest wall feeling. And it should be considered in the treatment of myasthenia gravis.

Gastrointestinal complications after cardiac surgery are rare, but they are associated with significant morbidity and mortality. The mechanisms of gastrointestinal complications after cardiac surgery may be unique, as the abdominal cavity is not involved. This review summarizes the current evidence of the pathophysiology, clinical manifestations, risk factors, and management of gastrointestinal complications after cardiac surgery, aiming to improve the recognition of gastrointestinal complications after cardiac surgery.
Objective To study the major postoperative complications of abdominal aortic aneurysm （AAA） repair in high-risk patients， analyze its causes， and suggest the prevention methods. Methods From January 2009 to September 2011， 57 cases of high-risk AAA patients underwent AAA repair in our hospital were analyzed retrospectively. High-risk patients were defined as age≥60 years，the American Society of Anesthesiologists grade three or four，and at least one of complications about heart， lung， and kidney. Major postoperative complications were rated， and preoperative cardiac，pulmonary， and renal condition，anesthesia and surgical impact were taken into account while evaluating the risk factors of major postoperative complications. Results Forty-one of 57 high-risk patients with AAA were repaired by endovascular repair，16 of 57 high-risk patients with AAA were repaired by traditional open surgery. The early mortality （within 30d） was 1.8% （1/57）. The major postoperative complications rate of AAA repair was 19.3% （11/57） in total，and 8.8% （5/57），8.8% （5/57），and 1.8% （1/57） for cardiac complication，pulmonary complication， and acute renal failure，respectively. The patients with coronary heart disease had a higher cardiac complication rate 〔19.0% （4/21） versus 2.8% （1/36），χ2=4.387，P＜0.05〕 ， while with hypertension had no such effect for that〔10.3% （4/39） versus 5.6% （1/18），χ2=0.340，P＞0.05〕. Patients with abnormal pulmonary function was responsible for postoperative respiratory complications 〔20.0% （4/20） versus 5.6% （1/18）， χ2=4.387， P＜0.05〕 ， while with chronic obstructive pulmonary disease history was not responsible for that 〔13.2% （5/38） versus 0 （0/19），χ2=2.740，P＞0.05〕．Patients with preoperative renal function was not related to postoperative acute renal failure 〔0 （0/4） versus 1.9% （1/53）， χ2=0.077，P＞0.05〕. Compared with traditional open surgery，endovascular repair could effectively reduce the incidence of postoperative complications 〔12.2% （5/41） versus 37.5% （6/16）， χ2=3.980，P＜0.05〕. The incidence of postoperative respiratory complications in the local anesthesia patients was less than that in the general anesthesia patients 〔0（0/20）versus 19.0% （4/21），χ2=4.221，P＜0.05〕. Conclusions Cardiac and pulmonary complications are commonly seen after AAA repair in high-risk patients．Preoperative cardiac，pulmonary condition，anesthesia and surgical aspects greatly influence the major postoperative complications. Exhaustively assessment of each system before surgery，appropriate anesthesia and surgical options，postoperative active and effective symptomatic，and supportive treatment are the key to reducing the incidence of postoperative complications.

Objective To explore the effect of preoperative hypothyroidism on postoperative cognition dysfunction (POCD) in elderly patients after on-pump cardiac surgery. Methods Patients who were no younger than 50 years and scheduled to have on-pump cardiac surgeries were selected in West China Hospital from March 2016 to December 2017. Based on hormone levels, patients were divided into two groups: a hypo group (hypothyroidism group, thyroid stimulating hormone (TSH) >4.2 mU/L or free triiodothyronine 3 (FT3) <3.60 pmol/L or FT4 <12.0 pmol/L) and an eu group (euthyroidism group, normal TSH, FT3 and FT4). The mini-mental state examination (MMSE) test and a battery of neuropsychological tests were used by a fixed researcher to assess cognitive function on 1 day before operation and 7 days after operation. Primer outcome was the incidence of POCD. Secondary outcomes were the incidence of cognitive degradation, scores or time cost in every aspect of cognitive function. Results No matter cognitive function was assessed by MMSE or a battery of neuropsychological tests, the incidence of POCD in the hypo group was higher than that of the eu group. The statistical significance existed when using MMSE (55.56% vs. 26.67%, P=0.014) but was absent when using a battery of neuropsychological tests (55.56% vs. 44.44%, P=0.361). The incidence of cognitive deterioration in the hypo group was higher than that in the eu group in verbal fluency test (48.15% vs. 20.00%, P=0.012). The cognitive deterioration incidence between the hypo group and the eu group was not statistically different in the other aspects of cognitive function. There was no statistical difference about scores or time cost between the hypo group and the eu group in all the aspects of cognitive function before surgery. After surgery, the scores between the hypo group and the eu group was statistically different in verbal fluency test (26.26±6.55 vs. 30.23±8.00, P=0.023) while was not statistically significant in other aspects of cognitive function. Conclusion The incidence of POCD is high in the elderly patients complicated with hypothyroidism after on-pump cardiac surgery and words reserve, fluency, and classification of cognitive function are significantly impacted by hypothyroidism over than other domains, which indicates hypothyroidism may have close relationship with POCD in this kind of patients.
Objective To analyze the influence of the ABO blood types of colorectal cancer patients served by West China Hospital as a regional center on surgical characteristics and postoperative complications in the current version of Database from Colorectal Cancer (DACCA). Methods The DACCA version was updated on January 5, 2022. The data items included ABO blood type, sex, type of operation, nature of operation and postoperative complications. The operative characteristics and complications at different stages after operation (in hospital, short-term and long-term after operation) of colorectal cancer patients with different blood types (A, B, AB, O) were analyzed. Results According to the DACCA database, we obtained 5 010 analysable data rows, covering 2005–2022. The results of blood types analysis showed that there was no significant difference among different blood types in the overall postoperative complications and the occurrence of complications in hospital, short-term and long-term after operation (P>0.05). Further subgroup analysis showed that only the difference of anastomotic leakage among different blood types was statistically significant (χ2=9.588, P=0.022). There was no significant difference among different blood types in whether the primary focus of colon cancer surgery was removed or not, the degree of radical resection of the primary focus, and whether the anus was preserved or not in rectal cancer surgery (P>0.05), and there was significant difference among different blood types with different degrees of radical resection of primary rectal cancer (χ2=15.773, P=0.001). Conclusions The ABO blood types of patients with colorectal cancer has nothing to do with the occurrence of overall complications in the short and long term after operation, and has no impact on the implementation of different surgical methods. However, the occurrence of a single postoperative anastomotic leakage is related to blood type, and its possible causes need to be further explored.
ObjectiveTo analyze the risk factors influencing major postoperative complications (MPC) after minimally invasive radical gastrectomy for gastric cancer following neoadjuvant chemotherapy (NACT), and to construct a nomogram for accurately predicting MPC risk factors, and provide a reference for clinical decision-making. MethodsThe gastric cancer patients who underwent minimally invasive radical gastrectomy in the Department of General Surgery of the First Medical Center of the Chinese PLA General Hospital from February 2012 to December 2022 and met the inclusion criteria of this study were retrospectively collected. The univariate and multivariate logistic regression model were used to evaluate the risk factors influencing MPC and a nomogram model was constructed. The MPC were defined as Clavien-Dindo classification grade Ⅱ and beyond. The area under the receiver operating characteristic curve (AUC) and the calibration curve were used to evaluate the discrimination and accuracy of the nomogram model. ResultsA total of 362 patients were included in this study, among whom 65 cases (18.0%) experienced MPC. The multivariate logistic regression analysis showed that the age ≥58 years old, body mass index (BMI) ≥25 kg/m2, tumor long diameter ≥30 mm, operative time ≥300 min, and preoperative neutrophil-to-lymphocyte ratio (NLR) ≥3.7 were the risk factors influencing MPC. The nomogram model constructed using the above variables showed that the AUC (95%CI) was 0.731 (0.662, 0.801) in predicting the risk of MPC. The calibration curves showed that the prediction curve of the nomogram in predicting the MPC was agree well with the actual MPC (Hosmer-Lemeshow test: χ2=9.293, P=0.056). ConclusionFrom the results of this study, nomogram model constructed by combining age, BMI, tumor long diameter, operative time, and preoperative NLR can distinguish between patients with and without MPC after minimally invasive radical gastrectomy for gastric cancer following NACT, and has a better accuracy.
ObjectiveTo systematically evaluate the measurement properties of observational pain assessment scales for pediatric patients after surgery. MethodsThe PubMed, Embase, CINAHL, PsycArticles, and SinoMed databases were electronically searched to collect studies related to the objects from inception to April 13, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. And the quality of measurement properties was rated using updated criteria for good measurement properties to determine recommendation levels. ResultsA total of 26 studies were finally included involving 12 observational pain assessment scales for pediatric patients after surgery. None reported measurement error or cross-cultural validity. The overall content validity of all 12 scales was evaluated by reviewers, with measurement properties rated as sufficient or inconsistent. For internal consistency, due to insufficient or uncertain content validity, the evidence quality was low. Eight scales calculated internal consistency, among which CHEOPS, CHIPPS, COMFORT, FLACC, and NCCPC-PV scales had sufficient measurement properties with evidence quality of low or above, receiving Grade A recommendations. ConclusionCompared with other scales, CHEOPS, CHIPPS, COMFORT, FLACC, and NCCPC-PV scales demonstrated good measurement property evaluation with acceptable evidence quality and can be recommended for use. Other scales still require further improvement in measurement property validation.
