Research progress of clinical prediction model in postoperative complications of gastric cancer

ObjectiveTo summarise the application research progress of clinical prediction models in postoperative complications of gastric cancer, in order to reduce the risk of complications after gastric cancer surgery. MethodThe literature on the study of postoperative complications of gastric cancer at home and abroad was read and reviewed. ResultsAt present, the main way of treating gastric cancer was still radical resection, and the occurrence of complications after surgical treatment seriously affected the recovery and survival quality of patients. With the deepening of research, the prediction models of postoperative complications in gastric cancer were constantly constructed, and these models provided strong evidence for the early judgement of postoperative complications in gastric cancer, and provided a scientific basis for the improvement of patients’ life quality. ConclusionClinical predictive models are expected to become risk screening tools for predicting the risk of postoperative complications of gastric cancer with clinical utility.

结直肠癌术后并发症的风险预测模型

目的探讨与结直肠癌术后并发症相关的主要危险因素并建立风险预测模型。方法回顾性收集 2015 年 1 月至 2016 年 12 月期间于新华医院崇明分院、堡镇医院及庙镇医院行结直肠癌手术且符合本研究纳入条件患者的临床病理资料，分析结直肠癌术后并发症发生的危险因素并建立风险预测模型，同时采用回代样本进行验证。结果本研究共纳入符合条件的结直肠癌手术患者 450 例，术后发生并发症 67 例，并发症发生率为 14.9%。单因素分析结果显示，患者的年龄高、合并糖尿病、合并心脑血管疾病、合并慢性阻塞性肺炎、无术前化疗、ASA 分级高、手术持续时间长、TNM 分期晚、肿瘤分化程度低、主刀手术例数少、术中输血及术前营养不良这 12 个因素与结直肠癌根治术后并发症发生有关（P<0.05）；进一步行多因素 logistic 回归分析结果显示，这 12 个因素是结直肠癌根治术后并发症发生的危险因素（P<0.05），通过将包括这 12 个危险因素与常数项建立的 logistic 回归风险模型判断结直肠癌术后并发症的灵敏度和特异度分别为 68.7%（46/67）和84.9%（325/383）；采用 40 例回代样本进行验证，此模型判断结直肠癌术后并发症的灵敏度和特异度分别为 66.7%（18/27）和 84.6%（11/13）。结论本研究根据多因素 logistic 回归分析得出了 12 项结直肠癌术后并发症发生独立的危险因素并以此建立的回归风险模型能够较为准确地预测结直肠癌术后的并发症发生率。

Meta-Analysis of Effect in Pericardial Devascularization for Patients with Portal Hypertension

ObjectiveTo analyze the effect and incidence rate of major postoperative complications of pericardial devascularization in treatment of portal hypertension. MethodsEnglish and Chinese literatures about pericardial deva-scularization in treatment of portal hypertension were searched through Medline, Elsevier, PubMed, CNKI, and WanFang database, and meta analysis was taken in the process by using R-2.15 software. ResultsIn total of 671 literatures were searched and 23 were selected finally according to inclusion criteria and exclusion criteria.The results of meta analysis showed that, the effect of pericardial devascularization in treatment of portal hypertension were as follows:the incidence rate of rebleeding was 21%(95% CI: 0.18-0.24), the incidence rate of hepatic encephalopathy was 4%(95% CI: 0.02-0.06), the incidence rate of ascites was 29%(95% CI: 0.14-0.47), mortality of operation was 3%(95% CI: 0.02-0.04), mortality was 23%(95% CI: 0.15-0.33). ConclusionsThere is a certain incidence rate of complications of pericardial devascularization, of which the most common complication is rebleeding.So, it is necessary to do further improvement and development of pericardial devascularization.

Hotspots and problems of basic research for diabetic retinopathy

Complications of proliferative diabetic retinopathy have become the major indications of vitrectomy. The surgery, however, is not basically a causative therapy. The visual function after operation depends on the degree of retinal ischemia and damage induced. The surgery itself has a potential for severe complications. Therefore it is important to better understand the pathology and to master surgical strategy and techniques in order to improve surgical outcomes and reduce the surgical complications.

Relationship between ABO blood type of patients with colorectal cancer and surgical characteristics and postoperative complications: a real world study based on DACCA

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.
