ObjectiveTo explore the effect of different ventilation modes on pulmonary complications (PCs) after laparoscopic weight loss surgery in obese patients. MethodsThe obese patients who underwent laparoscopic weight loss surgery in the Xiaolan People’s Hospital of Zhongshan from January 2019 to June 2023 were retrospectively collected, then were assigned into pressure-controlled ventilation-volume guaranteed (PCV-VG) group and volume controlled ventilation (VCV) group according to the different ventilation modes during anesthesia. The clinicopathologic data of the patients between the PCV-VG group and VCV group were compared. The occurrence of postoperative PCs was understood and the risk factors affecting the postoperative PCs for the obese patients underwent laparoscopic weight loss surgery were analyzed by multivariate logistic regression analysis. ResultsA total of 294 obese patients who underwent laparoscopic weight loss surgery were enrolled, with 138 males and 156 females; Body mass index (BMI) was 30–55 kg/m2, (42.40±4.87) kg/m2. The postoperative PCs occurred in 63 cases (21.4%). There were 160 cases in the PCV-VG group and 134 cases in the VCV group. The anesthesia time, tidal volume at 5 min after tracheal intubation, peak inspiratory pressure and driving pressure at 5 min after tracheal intubation, 60 min after establishing pneumoperitoneum, and the end of surgery, as well as incidence of postoperative PCs in the PCV-VG group were all less or lower than those in the VCV group (P<0.05). The indicators with statistical significance by univariate analysis in combination with significant clinical indicators were enrolled in the multivariate logistic regression model, such as the smoking history, American Society of Anesthesiologists classification, hypertension, BMI, operation time, forced expiratory volume in 1 second (FEV1), FEV1/forced vital capacity, and intraoperative ventilation mode. It was found that the factors had no collinearity (tolerance>0.1, and variance inflation factor<10). The results of the multivariate logistic regression analysis showed that the patients with higher BMI and intraoperative VCV mode increased the probability of postoperative PCs (P<0.05). ConclusionsFrom the preliminary results of this study, for the obese patients underwent laparoscopic weight loss surgery, the choice of ventilation mode is closely related to the risk of developing postoperative PCs. In clinical practice, it is particularly important to pay attention to the risk of postoperative PCs for the patients with higher degree obesity.
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.

Objective To gain accurate imaging information of biliary tract after surgery. MethodsThe biliary tract of 170 cases after surgery had been observed dynamically from different directions for longer time. The results of data on biliary tract change were stored in disc, or picture. ResultsOf 170 cases, 120 cases were cured without any abnormal change on cholangiography, and then the Ttube was removed. Of another 50 cases, 30 cases revealed remnant stone on cholangiography, 9 cases showed inflammatory stricture of biliary tract, 4 cases displayed common bile duct tumor, and 7 cases had false fillingdefect. Then, the results were further confirmed by sonography, CT, choledochoscopy, and operation. Conclusion The dynamic observation of biliary tract by Ttube cholangiography after surgery is usual way that is handy, practical, painless, and economic.
ObjectiveTo understand the impact of preoperative nutritional status on the postoperative complications for patients with low/ultra-low rectal cancer undergoing extreme sphincter-preserving surgery following neoadjuvant therapy. MethodsThe patients with low/ultra-low rectal cancer who underwent extreme sphincter-preserving surgery following neoadjuvant therapy from January 2009 to December 2020 were retrospectively collected using the Database from Colorectal Cancer (DACCA), and then who were assigned into a nutritional risk group (the score was low than 3 by the Nutrition Risk Screening 2002) and non-nutritional risk group (the score was 3 or more by the Nutrition Risk Screening 2002). The postoperative complications and survival were analyzed for the patients with or without nutritional risk. The postoperative complications were defined as early-term (complications occurring within 30 d after surgery), middle-term (complications occurring during 30–180 d after surgery), and long-term (complications occurring at 180 d and more after surgery). The survival indicators included overall survival and disease-specific survival. ResultsA total of 680 patients who met the inclusion criteria for this study were retrieved from the DACCA database. Among them, there were 500 (73.5%) patients without nutritional risk and 180 (26.5%) patients with nutritional risk. The postoperative follow-up time was 0–152 months (with average 48.9 months). Five hundreds and forty-three survived, including 471 (86.7%) patients with free-tumors survival and 72 (13.3%) patients with tumors survival. There were 137 deaths, including 122 (89.1%) patients with cancer related deaths and 15 (10.9%) patients with non-cancer related deaths. There were 48 (7.1%) cases of early-term postoperative complications, 51 (7.5%) cases of middle-term complications, and 17 (2.5%) cases of long-term complications. There were no statistical differences in the incidence of overall complications between the patients with and without nutritional risk (χ2=3.749, P=0.053; χ2=2.205, P=0.138; χ2=310, P=0.578). The specific complications at different stages after surgery (excluding the anastomotic leakage complications in the patients with nutritional risk was higher in patients without nutritional risk, P=0.034) had no statistical differences between the two groups (P>0.05). The survival curves (overall survival and disease-specific survival) using the Kaplan-Meier method had no statistical differences between the patients with and without nutritional risk (χ2=3.316, P=0.069; χ2=3.712, P=0.054). ConclusionsFrom the analysis results of this study, for the rectal cancer patients who underwent extreme sphincter-preserving surgery following neoadjuvant therapy, the patients with preoperative nutritional risk are more prone to anastomotic leakage within 30 d after surgery. Although other postoperative complications and long-term survival outcomes have no statistical differences between patients with and without nutritional risk, preoperative nutritional management for them cannot be ignored.
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.
