Gastroparesis is a gastrointestinal motility disorder that refers to delayed gastric emptying in the absence of mechanical obstruction. Clinical manifestations include postprandial fullness and epigastric discomfort, abdominal distension, nausea, and vomiting. According to its etiology, it can be divided into three categories: surgery-related gastroparesis, non-surgery-related gastroparesis and idiopathic gastroparesis. Non-surgery-related gastroparesis is common clinically. At present, the exact pathogenesis of gastroparesis remains to be unclear. The intestinal flora is huge and abundant. It participates in a variety of physiological functions of the host. Studies have confirmed that the intestinal flora is related to perioperative treatment measures, surgical stress, and various system diseases (endocrine and metabolic system diseases, nervous system diseases, and immune system diseases), especially the weakening of gastrointestinal motility, and gastrointestinal motility. Attenuation can further promote the occurrence and development of gastroparesis. Based on the current research, this article reviews the research on the correlation between gastroparesis and intestinal flora.
ObjectiveTo systematically evaluate the efficacy of adjuvant radiotherapy after thymoma resection. MethodsThe PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP, CNKI databases were systematically searched to find relevant literature comparing the efficacy and effectiveness of thymoma resection and thymoma resection+postoperative radiation therapy (PORT) for treating thymoma published from inception to January 2024. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included retrospective studies, and Review Manager 5.4 software was used to perform meta-analysis. ResultsA total of 23 articles were included, all of which were retrospective studies. There were a total of 13742 patients, including 6980 patients in the simple surgery group, with 3321 males and 3659 females, and an average age of 54.08 years; 6762 patients in the surgery+PORT group, with 3385 males and 3377 females, and an average age of 53.76 years. The NOS scores of the included literature were all≥7 points. The results of the meta-analysis showed that compared with the simple surgery group, the surgery+PORT group had higher 1-year overall survival rate [OR=0.32, 95%CI (0.25, 0.42), P<0.001], 3-year overall survival rate [OR=0.55, 95%CI (0.48, 0.64), P<0.001], 5-year overall survival rate [OR=0.66, 95%CI (0.58, 0.75), P<0.001], 10-year overall survival rate [OR=0.71, 95%CI (0.57, 0.88), P=0.002], 1-year disease-free survival rate [OR=0.47, 95%CI (0.23, 0.93), P=0.030], 5-year disease-free survival rate [OR=0.61, 95%CI (0.45, 0.84), P=0.003], 3-year disease-specific survival rate [OR=0.44, 95%CI (0.35, 0.55), P<0.001], 5-year disease-specific survival rate [OR=0.53, 95%CI (0.44, 0.63), P<0.001] and 10-year disease-specific survival rate [OR=0.53, 95%CI (0.35, 0.82), P=0.004]. But there was no statistically significant difference between the two groups in terms of 3-year disease-free survival rate [OR=0.86, 95%CI (0.61, 1.22), P=0.400], 10-year disease-free survival rate [OR=0.70, 95%CI (0.47, 1.05), P=0.080] and 1-year disease-specific survival rate [OR=0.83, 95%CI (0.55, 1.26), P=0.380]. ConclusionPORT after thymoma resection has more advantages than simple surgical treatment in terms of 1-, 3-, 5-, and 10-year overall survival, 1- and 5-year disease-free survival, and 3-, 5- and 10-year disease-specific survival.
Objective To compare the efficacy and safety of intra-articular combined with intravenous administration of tranexamic acid (TXA) with different dosage for reducing blood loss in primary total knee arthroplasty (TKA). Methods Between January 2017 and June 2017, 90 patients suffering from unilateral osteoarthritis who underwent primary TKA were randomly scheduled to three interventions, named groups A, B, and C. Single dosage of TXA via intravenous injection (IV) and different dosages of TXA via intra-articular injection (IA) were utilized in three groups, respectively. All patients in three groups received 1 g TXA IV at 10 minutes preoperatively, and received 1, 2, and 3 g TXA IA diluted in 50 mL saline after wound closure in groups A, B and C, respectively. The age, gender, body mass index, affected side of the knee, grade of osteoarthritis, grade of America Society of Anesthesiologist, preoperative hemoglobin (Hb) concentration, platelet count, preoperative prothrombin time, and activated partial thromboplastin time were not significantly different between groups (P>0.05). The postoperative wound blood drainage, Hb concentration at 1, 3, and 7 days after operation, transfusion rate, and thromboembolic complications were observed. All patients were routinely observed for deep vein thrombosis (DVT) by the color Doppler ultrasonography at 1 week, 1 month, and 3 months after operation, and the symptomatic pulmonary embolism (PE) were observed. Results All patients in three groups were followed up 7-12 months (mean, 8.4 months). There was no significant difference in operation time between groups (P>0.05). The postoperative wound blood drainage was significantly less in groups B and C than that in group A (P<0.05), whereas no significant difference was found between group B and group C (P>0.05). Incision skin necrosis occurred in 1 case of group B and fat liquefaction occurred in 1 case of group C. The other incisions of 3 groups healed by first intention. There was no significant difference in incision complication incidence between groups. The Hb concentration was significantly higher in groups B and C than that in group A at 1, 3, and 7 days after operation (P<0.05). While between group B and group C, the significant difference of Hb concentration only existed at 1 day after operation (P<0.05). The number of patients who got blood transfusion was significantly less in group B (4 cases, 13.3%) and group C (5 cases, 16.7%) than that in group A (9 cases, 30%) (P< 0.05), but no significant difference was found between group B and group C (P>0.05). The result of color Doppler ultrasonography showed that 1 case got DVT in the contralateral calf at 3 weeks in group B. And there was no symptomatic PE in 3 groups. Conclusion Combined administration of IV and IA TXA in a clinically relevant reduction in blood loss was effective and safe in primary TKA, and no thromboembolic complication was observed. The combination of 1 g IV with 2 g IA could be the optional choice.
ObjectiveTo investigate the clinical value of prophylactic high-flow nasal cannula oxygen therapy (HFNC) in reducing postoperative pulmonary complication (PPC) in elderly patients with non-small cell lung cancer (NSCLC). Methods The clinical data of elderly patients (over 60 years) with NSCLC who underwent video-assisted thoracoscopic lobectomy or segmental resection at the Department of Thoracic Surgery, Fujian Provincial Hospital from January 2021 to March 2022 were retrospectively analyzed. According to whether receiving HFNC after surgery, they were divided into a conventional oxygen therapy (CO) group and a HFNC group. The CO group were matched with the HFNC group by the propensity score matching method at a ratio of 1 : 1. We compared PPC incidence, white blood cell (WBC) count, procalcitonin and C-reactive protein on postoperative day (POD) 1, 3 and 5 and postoperative hospital stay between the two groups. ResultsA total of 343 patients (165 males, 178 females, average age of 67.25±4.79 years) were enrolled, with 53 (15.45%) receiving HFNC. Before matching, there were statistical differences in gender, rate of combined chronic obstructive pulmonary disease, pathology type and TNM stage between the two groups (all P<0.05). There were 42 patients successfully matched in each of the two groups, with no statistical difference in baseline characteristics (P>0.05). After propensity score matching, the results showed that the PPC incidence in the HFNC group was lower than that in the CO group (23.81% vs. 45.23%, P=0.039). WBC count on POD 3 and 5 and procalcitonin level on POD 3 were less or lower in the HFNC group than those in the CO group [ (8.92±2.91)×109/L vs. (10.62±2.67)×109/L; (7.68±1.58)×109/L vs. (8.86±1.76)×109/L; 0.26 (0.25, 0.44) μg/L vs. 0.31 (0.25, 0.86) μg/L; all P<0.05]. There was no statistical difference in the other inflammatory indexes or the postoperative hospital stay between the two groups (P>0.05). Conclusion Prophylactic HFNC can reduce the PPC incidence and postoperative inflammatory indexes in elderly patients with NSCLC, but does not shorten the postoperative hospital stay.
Objective To summarize the clinical data about mediastinal lesions, then to analyze the treatment effect of da Vinci robot system in the surgical treatment of mediastinal lesions. Methods We retrospectively analyzed the clinical data of 49 patients with mediastinal lesions in our hospital between January 2016 and October 2017. These patients were divided into two groups including a da Vinci robot group and a video-assisted thoracoscopic surgery (VATS) group according to the selection of the treatments. There were 25 patients with 14 males and 11 females at age of 56.5±17.9 years in the da Vinci group and 24 patient with 15 males and 11 females at age of 53.0±17.8 years in the VATS group. Results There was no statistical difference in surgery time between the two groups (t=–0.365, P=0.681). Less intraoperative blood loss (t=–2.569, P<0.001), less postoperative drainage amount within three days after surgery (t=–6.325, P=0.045), shorter period of bearing drainage tubes after surgery (t=–1.687, P=0.024), shorter hospital stays (t=–3.689, P=0.021), lower visual analogue scale (VAS) scores of postoperative 48 hours (t=–7.214, P=0.014) with a statistical difference in the da Vinci robot group compared with the VATS group. Conclusion The da Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach.
Objective To evaluate the association between intraoperative fluid management and prolonged postoperative ileus (PPOI) after colorectal surgery. Methods We reviewed the data of 980 patients who underwent elective colorectal surgery in West China Hospital of Sichuan University between July and December 2016. The primary outcome was PPOI. The association of intraoperative fluid volume and fluid balance with PPOI were analyzed. Results Nine hundred and eighty patients undergoing elective colorectal surgery were included, and the incidence of PPOI was 31.1% (305/980). Compared with non-PPOI patients, patients with PPOI had longer postoperative hospital stay and increased total hospital cost (P<0.05). Multivariate logistic regression analysis did not find intraoperative fluid volume and fluid balance were associated with PPOI in patients undergoing colorectal surgery (P>0.05). Conclusions There is no clinically relevant association between intraoperative fluid management and PPOI in adult patients underwent colorectal surgery. However, the occurrence of PPOI may prolong postoperative hospital stay and increase hospitalization cost.
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.
Objective To evaluate the association between pressure-controlled ventilation-volume guaranteed (PCV-VG) mode and volume-controlled ventilation (VCV) mode on postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung resection. Methods A retrospective cohort analysis of 329 patients undergoing elective thoracoscopic lung resection in West China Hospital of Sichuan University between September 2020 and March 2021 was conducted, including 213 females and 116 males, aged 53.6±11.3 years. American Society of Anesthesiologists (ASA) grade wasⅠ-Ⅲ. The patients who received lung-protective ventilation strategy during anesthesia were divided into a PCV-VG group (n=165) and a VCV group (n=164) according to intraoperative ventilation mode. Primary outcome was the incidence of PPCs during hospitalization. Results A total of 73 (22.2%) patients developed PPCs during hospitalization. The PPCs incidence of PCV-VG and VCV was 21.8% and 22.6%, respectively (RR=0.985, 95%CI 0.569-1.611, P=0.871). Multivariate logistic regression analysis showed that there was no statistical difference in the incidence of PPCs between PCV-VG and VCV mode during hospitalization (OR=0.846, 95%CI 0.487-1.470, P=0.553). Conclusion Among patients undergoing thoracoscopic lung resection, intraoperative ventilation mode (PCV-VG or VCV) is not associated with the risk of PPCs during hospitalization.
ObjectiveTo summarize the methods to prevent pulmonary complications in patients underwent abdominal surgery during perioperative period and provide reference for the prevention of postoperative pulmonary complications.MethodLiteratures on the prevention of pulmonary complications after abdominal surgery were searched and reviewed.ResultsThe prevention of pulmonary complications after abdominal surgery included preoperative measures, intraoperative measures, and postoperative measures. Preoperative measures included preoperative education, patient risk assessment, smoking cessation, and so on. Intraoperative measures included anesthetic measures and surgical measures. Postoperative measures included atomization treatment, elimination of bad feelings, early postoperative activities, and so on. In view of the different basic conditions of patients underwent abdominal surgery, the selection and emphasis of preventive measures were also different.ConclusionThe prevention of postoperative pulmonary complications after general abdominal surgery should not only take preventive measures in perioperative period, but also should carry out individual management according to the patient’s condition and general conditions.
[Abstract]Postoperative lung cancer patients experience a significant symptom burden that severely impacts their quality of life. Accurate assessment of their health experience during recovery is critical to postoperative management. Patient-reported outcomes (PROs), which provide valuable insights into health from the patient's perspective, are increasingly used in the postoperative management of lung cancer patients. This article reviews the existing patient-reported outcome measures (PROMs) for lung cancer patients, focusing on their measurement dimensions, clinical applicability, and current usage. It aims to provide a foundation for their scientific application, optimize postoperative management strategies, and promote high-quality recovery and management.
