ObjectiveTo explore the clinicopathological features of pulmonary alveolar proteinosis (PAP).MethodsA total of 25 patients with PAP who were pathologically diagnosed in West China Hospital of Sichuan University from 2014 to 2018 were collected as the study subjects.ResultsThe 25 patients with PAP were 18–73 years old, with an average age of (42.52±15.79) years. There were 20 males and 5 females. The most common type was autoimmune PAP (15 cases), and secondary PAP (10 cases) were found in patients with pneumonia, tuberculosis, nephrotic syndrome, and pneumoconiosis. The common clinical symptoms of PAP were cough (24 cases), expectoration (20 cases), and progressive difficulty in breathing (11 cases of shortness of breath and 5 cases of dyspnea). The chest CT manifestations included double lung grinding (19 cases), grid-like changes (11 cases), and map-like changes (3 cases). Periodic acid-schiff (PAS) staining and post-digestion PAS staining double positive lipoprotein-like deposits was observed in lung biopsy (in the alveolar cavity) and/or alveolar lavage fluids.ConclusionsPAP has no characteristic clinical symptoms and a long diagnosis period. Clinicians should combine clinical signs, imaging features, and lung biopsy and/or alveolar lavage fluid PAS staining and post-digestion PAS staining to confirm the diagnosis.
Objective To explore the related factors of postoperative pulmonary infection (PPI) in patients undergoing laparoscopic colorectal cancer surgery, and analyze the perioperative management strategy of pulmonary infection combined with the concept of enhanced recovery after surgery (ERAS). Methods Total of 687 patients who underwent laparoscopic colorectal cancer surgery in the colorectal cancer professional treatment group of Gastrointestinal Surgery Center of West China Hospital of Sichuan University from January 2017 to May 2019 were retrospectively included. According to the occurrence of PPI, all the included cases were divided into infection group (n=97) and non-infection group (n=590). The related factors and prevention strategies of PPI were analyzed. Results The rate of PPI among patients underwent laparoscopic resection in our study was 14.1% (97/687). Compared with the non-infection group, the proportions of patients with preoperative complications other than cardiopulmonary, receiving preoperative neoadjuvant radiotherapy and/or chemotherapy, preoperative Eastern Cooperative Oncology Group (ECOG) score 1–2, preoperative Nutrition Risk Screening 2002 (NRS2002) score 1–3, tumor located in the left colon and rectum, combined organ resection, operative time >3 h and postoperative TNM stage Ⅱ patients in the infection group were higher (P<0.05). However, the proportions of patients who used intraoperative lung protective ventilation strategy and incision infiltration anesthesia in the infection group were lower than those in the non-infection group (P<0.05). In the infection group, the proportions of patients who received regular sputum excretion, atomization therapy, balloon blowing/breathing training, stomatology nursing after operation and postoperative analgesia were all significantly lower than those of the non-infection group (P<0.05), whereas the proportions of patients receiving antibiotics and intravenous nutrition after operation were significantly higher than those in the non-infection group (P<0.05). Logistic regression analysis showed that low preoperative NRS2002 score, intraoperative protective ventilation strategy, postoperative respiratory training, and postoperative regular sputum excretion were the protective factors of PPI, while preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor located in the left colon and rectum, late TNM staging and postoperative antibiotics were risk factors for pulmonary infection.Conclusions Preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor location in the left colon and rectum, late TNM staging and postoperative antibiotics are risk factors for pulmonary infection in patients with laparoscopic colorectal cancer. Preoperative good nutritional status, intraoperative protective ventilation strategy, postoperative respiratory training and regular sputum excretion may reduce the incidence of PPI to a certain extent.
Objective To compare the differences in evaluating readiness for hospital discharge between nurses and colorectal cancer (CRC) patients following enhanced recovery after surgery (ERAS) pathway. Methods A cross-sectional survey was conducted in Department of Gastrointestinal Surgery, West China Hospital, Sichuan University. Patient-reported Readiness for Hospital Discharge Scale (RHDS) and nurse-reported RHDS were delivered to 130 CRC patients and 40 nurses respectively. All patients were followed ERAS pathway during perioperative periods. The differences were compared in evaluating readiness for hospital discharge between nurses and CRC patients. Results This study investigated 130 CRC patients and 40 responsible nurses. The scores of RHDS from nurses and patients were 162.86±27.95 and 149.86±33.65 respectively. When evaluating whether patients were ready to go home after discharge, the consistency between nurses’ results and patients’ results was weak（κ=0.365, P<0.001）. Items in patients’ RHDS scoring ranking from high to low were expected support, coping ability, knowledge, and personal status. Items in nurses’ RHDS scoring ranking from high to low were expected support, knowledge, coping ability, and personal status. Besides the " social support” dimension, the scores of other 3 dimensions from nurses were significantly higher than those from patients (P<0.05). Conclusion There is a gap between the assessment of RHDS from nurses and patients, nurses overestimated patients’ discharge readiness level.
Objective To study the effect of indirect calorimetry-guided nutritional support on energy metabolism, cellular immunity and oxidative stress in patients with colorectal cancer after laparoscopic surgery. Methods A total of 96 patients with colorectal cancer after laparoscopic surgery in our hospital from December 2019 to December 2021 were selected and randomly divided into the control group (used the formula prediction method to guide enteral nutrition support, n=48) and the observation group (used indirect calorimetry to guide enteral nutrition support, n=48). The target resting energy expenditure (REE) value and nutritional support energy intake were compared between the two groups. The cellular immune indexes (CD3+, CD4+, CD8+, CD4+/CD8+) and oxidative stress indexes [serum superoxide dismutase (SOD), malondialdehyde (MDA), the changes of glutathione peroxidase (GSH-Px)], and the changes of REE at different time points (1 day before operation and 1, 2 and 3 days after operation) of the two groups were compared. The incidence of complications in the two groups were observed. Results The target REE value of the observation group was lower than that of the control group (P＜0.05), and there was no significant difference in the enteral energy intake and parenteral energy intake compared with the control group (P＞0.05). After treatment, CD3+, CD4+ and CD4+/CD8+ in the two groups were lower than those before treatment (P<0.05), and CD8+ was higher than before treatment (P<0.05). The levels of CD3+, CD4+ and CD4+/CD8+ in the observation group after treatment were higher than those in the control group (P<0.05) , while the level of CD8+ in the observation group was lower than that in the control group (P<0.05). After treatment, the levels of SOD and GSH-Px in the two groups were lower than those before treatment (P<0.05), and the levels of MDA were higher than those before treatment (P<0.05). The levels of GSH-Px and SOD in the observation group were higher than those in the control group (P<0.05), while the level of MDA in the observation group was lower than that in the control group (P<0.05). There was no significant difference in the REE value between the two groups at 1 day before operation (P>0.05); compared with the 1 day before operation, the REE values of the two groups at 1, 2, and 3 days after operation were significantly increased, and there was a statistically significant difference between the two groups at each time point (P<0.05), but the REE value at 3 days after operation was significantly lower than that at 1 and 2 days after operation (P<0.05). The REE values in the observation group were lower than those in the control group at 1, 2 and 3 days after operation (P<0.05). The incidence of complications in the observation group was 6.25%, which was lower than 20.83% in the control group (P<0.05). Conclusion Enteral nutrition support guided by indirect calorimetry in colorectal cancer patients after laparoscopic surgery can help reduce postoperative energy consumption, improve cellular immune function and oxidative stress response, and reduce the risk of postoperative complications, which is worthy of promotion.
ObjectiveTo understand the current situation and factors affecting tube blockage (non-mechanical) during hyperthermic intraperitoneal chemotherapy (HIPEC). MethodsAccording to the inclusion and exclusion criteria, the patients with malignant tumors who underwent HIPEC in the Department of Gastroenterology of West China Hospital of Sichuan University from May 2019 to May 2021 were retrospectively gathered. The information about the patient and the occurrence of occlusion during HIPEC were obtained by consulting electronic medical records and perfusion records. The logistic regression analysis was performed to analyze the factors influencing non-mechanical tube blockage during HIPEC. ResultsA total of 240 patients with malignant tumors were gathered. During HIPEC, the non-mechanical tube blockage occurred in 88 patients with malignant tumors, with the incidence of 36.7%. The multivariate analysis results by logistic regression showed that the probabilities of non-mechanical tube blockage during HIPEC were higher in the patients with age≥65 years (OR=2.142, P=0.016), diabetes mellitus (OR=2.326, P=0.007), perfusion speed of 300–450 mL/min (OR=2.778, P=0.001), ascites (OR=2.192, P=0.020), and PCI ≥20 points (OR=4.380, P<0.001). ConclusionsPatients with malignant tumors treated with HIPEC are prone to non-mechanical tube blockage. The patients with middle-aged and elderly, diabetes, low perfusion speed, ascites, and high PCI score need to be of great concern, so as to prevent and deal with tube blockage in time.
ObjectiveTo investigate the prevalence of early mobilization and it’s influencing factors in colorectal cancer patients who underwent enhanced recovery after surgery (ERAS) pathway. MethodsThe geneal data and perioperative data were collected through questionnaire survey and accessing to the hospital information system. The situation of early mobilization was investigated by bedside inquiry. Logistic regression was used to analyze the influencing factors of early mobilization in the patients with colorectal cancer. ResultsIn this study, 300 patients with colorectal cancer underwent ERAS were selected. Within 24 h after operation, 47 patients got out of bed, the early mobilization rate was 15.7%. Logistic regression results showed that the patients without preoperative complications (OR=2.726, P=0.019) and without preoperative nutritional risk (OR=3.621, P=0.013), and with operation time <3 h (OR=2.246, P=0.032) increased the probability of early mobilization, and preoperative low albumin decreased the probability of early mobilization (OR=0.364, P=0.007). ConclusionsEarly mobilization rate of patients with colorectal cancer in ERAS mode is low. Preoperative complications, preoperative albumin level, preoperative NRS2002 score, and operation time were important influencing factors. Active treatment of preoperative complications and improvement of preoperative nutritional status could make patients bear follow-up stress process with better physical condition, which helps to promote early mobilization.
Objective To compare the clinical effect between alginate calcium dressing and radix yarn dressing after anal fistula surgery. Methods A survey of 128 patients with anal fistula from April to October 2008 were studied. Patients were divided into two groups using a simple random method: 64 cases in therapy group which were treated with alginate calcium dressing and 64 cases in control group which were treated with traditional radix yarn dressing. The difference of the wound recovery indexes between two groups was compared.Results With regard to age, gender, anal fistula type, the proportion of preoperative diabetes and the diameter of wound, there was no statistical significance between therapy group and control group (Pgt;0.05). The proportion of slight pain during dressing change in therapy group (45.32%, 29/64) was more than control group (25.00%, 16/64), which had statistical significance (Pgt;0.05). The incidence of skin allergy was significantly different between two groups (29.69% vs. 60.94%, P＜0.05). Also, the rotten tissue and the soakage disappears with a shorter period, which both had statistical significance 〔(8.60±2.37) d vs. (12.22±3.29) d， (16.96±5.83) d vs. (22.02±5.90) d〕， Plt;0.05.Conclusion With the shorten of inflammatory and increment stage of the wound recovery, alginate calcium dressing is an ideal material for the postoperative duration of surgery of anal fistula.
ObjectiveTo explore the influence of enhanced recovery after surgery (ERAS) on intestinal flora in patients with colorectal cancer.MethodsBy convenient sampling method, 60 patients with colorectal cancer were selected from August 2018 to December 2019 in the Department of Gastrointestinal Surgery of West China Hospital of Sichuan University and randomly divided into ERAS group and traditional treatment group (traditional group). Among them, the perioperative clinical management was carried out according to the ERAS management and traditional treatment process in the the ERAS group and in the traditional group, respectively. The fresh fecal samples were collected within 24 h after admission and the first natural defecation after operation. The bacterial 16 Sr DNA V3–V4 region was sequenced by Illumina MiSeq sequencer, and the results were analyzed by bioinformatics.ResultsA total of 60 patients with colorectal cancer were included, 30 cases in the traditional group and 27 cases in the ERAS group (3 people temporarily withdrew from the study). There were no significant differences in the basic informations between the two groups (P>0.05). ① Before or after operation, there were no significant differences in Shannon index and Simpson index between the two groups. The difference between preoperative and postoperative comparison in the same group was also not statistically significant (P>0.05). ② Beta diversity analysis showed that there was no significant difference in community composition between the traditional group and the ERAS group before operation, and there was a clear boundary between the traditional group and the ERAS group after operation. ③ At the phylum level, compared with the preoperative abundance, the postoperative abundance Firmicutes decreased by 26.5% and 5.5% in the traditional and ERAS group, respectively; Bacteroidetes increased by 21.6% and 4.7% in the traditional and ERAS group, respectively; Proteobacteria increased by 7.2% and 2.2% in the traditional and ERAS group, respectively. At the genus level, compared with the preoperative abundance, the postoperative abundance of Bacteroides in the traditional group increased by 17.6% and in the ERAS group decreased by 1.6%; Bifidobacterium decreased by 1.8% and 1.3% in the traditional group and in the ERAS group, respectively.ConclusionsERAS does not affect species diversity of intestinal flora. Although ERAS has some damage to structure of intestinal flora, it is weaker than traditional process, so it is more conducive to reconstruction and restoration of intestinal microecological environment.
ObjectiveTo systematically analyze prognostic factors in acute fibrinous and organizing pneumonia (AFOP) and provide evidence for optimizing clinical management strategies for improved patient outcomes. MethodsWe searched the Medline, Web of Science, CNKI and Wanfang databases to identify studies that met predefined criteria, from which we extracted individual patient data (IPD). Clinical characteristics were compared among groups (Survival without recurrence, Survival with recurrence, Death, Lung transplantation) using univariate analysis. Additionally, the Random Forest model was employed to assess the importance of factors associated with these prognostic outcomes. ResultsIPD, which were extracted from 179 patients across 130 studies, were analyzed. Intergroup comparisons revealed that the death group exhibited the highest rate of combined antibiotic-glucocorticoid therapy, with the earliest glucocorticoid initiation, highest doses, yet shortest treatment duration, a profile likely reflecting confounding by indication due to more rapidly progressive disease. After excluding hyper-acute cases, restricted cubic spline (RCS) analysis further suggested that earlier initiation of corticosteroid therapy (within 0-15 days) was associated with a lower risk of death. Diagnostic delay was also significantly associated with poor outcomes (P=0.015). The average diagnostic delay was significantly higher in the death group than the survival without recurrence group (42.4 days vs. 26.2 days). Hematologic diseases were the most frequent comorbidity among both survivors and non-survivors, occurring more often in the death group (39.5%, 15/38) than in the survival group (14.7%, 17/116). Random Forest analysis identified the treatment regimens as the most significant predictors of prognosis, likely reflects confounding by indication, followed by diagnostic delay, age, duration of corticosteroid maintenance, and time from symptom onset to corticosteroid therapy.ConclusionThe treatment regimen, diagnostic delay, and timing of therapeutic intervention are key factors influencing AFOP prognosis. These findings suggest that clinical practice should focus on shortening the diagnostic delay to achieve prompt diagnosis and initiate glucocorticoid therapy accordingly. However, treatment regimens must be individualized based on the patient’s age, underlying diseases, and disease severity.
