ObjectiveTo analyze the relationship between preoperative pulmonary function indexes and postoperative pneumonia (POP) in patients undergoing upper gastrointestinal surgery.MethodsThe clinical data of 303 patients who underwent lung function examination and upper gastrointestinal surgery in West China Hospital, Sichuan University from September 2020 to January 2021 were prospectively collected and analyzed. There were 217 males and 86 females, with an average age of 61.61±10.42 years. Pulmonary function was evaluated from four aspects including ventilatory function, pulmonary volume, diffusion function and airway resistance. Relevant pulmonary function indicators were displayed as the percentage of actual measured value to predicted value (%pred). The outcome index was pneumonia within 30 days after the surgery. Logistic regression was used to analyze the relationship between preoperative pulmonary function indicators and POP.ResultsA total of 196 patients with gastric cancer and 107 patients with esophageal cancer were included, and the incidence of POP in patients undergoing upper gastrointestinal surgery was 26.7% (81/303). Patients with preoperative low peak expiratory flow (PEF%pred) had a 3.094 times higher risk of developing POP than those with normal PEF%pred [OR=3.094, 95%CI (1.362, 7.032), P=0.007]. The incidence of POP had no correlation with the other preoperative indicators.ConclusionPreoperative PEF%pred may be an important indicator for predicting the occurrence of POP in patients undergoing upper gastrointestinal surgery.
【Abstract】ObjectiveTo summarize the study on the feasibility of celiac axis ligation. Methods Literatures about celiac axis ligation were reviewed retrospectively. ResultsCeliac axis branches included common hepatic artery， splenic artery， left gastric artery which had many variation and collateral flow between celiac and mesenteric vessels by gastroduodenal artery and pancreaticoduodenal artery. Celiac axis could be possibly ligated without obvious complications in patients who had celiac axis injuries, celiac artery aneurysms, upper gastrointestinal haemorrhage, excision of carcinoma around the celiac axis and portal hypertension. However, gallbladder necrosis or perforation, focal infarction of the liver even higher mortality had also been reported. ConclusionCeliac axis ligation should not be performed routinely, but it is surgically possible and may be a life saving approach in certain circumstances.
The incidence and mortality of esophageal cancer are high, with strong invasiveness and poor prognosis. In China, the number of morbidity and death accounts for about half of the world. The cause of the disease has not yet been clarified, and it is known to be related to many factors such as chronic damage to the upper digestive tract caused by poor diet and lifestyle, heredity and environment. With the continuous advancement of molecular biology technology, metagenomics and high-throughput sequencing began to be used as non-culture methods instead of traditional culture methods for micro-ecological analysis, and is becoming a research hotspot. Many studies have shown that the disturbance of upper digestive tract microecology may be one of the causes of esophageal cancer, which affects the occurrence and development of esophageal cancer through complex interactions with the body and various mechanisms. This paper reviews the research progress, which is of great significance to further clarify the value of upper gastrointestinal microecology in the pathogenesis, diagnosis and treatment of esophageal cancer.
Objective To analyze and summarize the clinical characteristics of foreign body incarceration in upper digestive tract, and to explore the risk factors of its complications. Methods The clinical data of patients with foreign bodies in the upper digestive tract treated in the Affiliated Hospital of Zunyi Medical University between January 1, 2012 and December 31, 2021 were retrospectively analyzed, including demographic data, foreign body type, incarceration site, incarceration time, causes, symptoms, treatment methods and complications of foreign body incarceration. Logistic regression analysis was used to explore the risk factors of complications. Results A total of 721 patients were finally included, ranging in age from 3 months to 90 years old, with an average age of 26.76 years. The proportion of foreign bodies in the upper digestive tract in patients ≤14 years old was the highest (51.18%), and the duration of foreign body incarceration<12 hours was the highest (55.34%). The most common sharp foreign bodies in the upper digestive tract were animal bones (228 cases), and the most common round shaped foreign bodies were coins (223 cases). The most common impaction site was the upper esophageal segment (85.02%). 105 patients (14.56%) had complications, and perforation was the most common (5.55%). Logistic regression analysis showed that age [odds ratio (OR)=0.523, 95% confidence interval (CI) (0.312, 0.875), P=0.014], foreign body type [OR=0.520, 95%CI (0.330, 0.820), P=0.005], incarceration site [OR=2.347, 95%CI (1.396, 3.947), P=0.001], incarceration time [OR=0.464, 95%CI (0.293, 0.736), P=0.001] were the influencing factors of complications. Conclusions The majority of foreign bodies in the upper digestive tract are animal bones. The incidence of complications increase in patients with age ≥ 60 years, sharp foreign body edges, incarceration in the upper segment of the esophagus, and long incarceration time. It is recommended to remove the sharp foreign bodies incarcerated in the upper segment of the esophagus from the elderly as soon as possible.
Objective To systematically evaluate the effectiveness and safety of China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding. Methods Such databases as PubMed, MEDLINE, Springer, The Cochrane Library, CNKI, VIP, CBM and WanFang data were searched to collect the randomized controlled trials (RCTs) about China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding, and the references of included studies were also retrieved. The retrieval time was from inception to December 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.1 software. Results A total of 11 RCTs were included. Among all 1 075 patients, 544 were in the treatment group, while the other 531 were in the control group. The results of meta-analysis showed that, there were no significant differences in the total effective rate (OR=0.68, 95%CI 0.35 to 1.33, P=0.26) and safety (RR=1.33, 95%CI 0.45 to 3.91, P=0.96) between the China-made omeprazole and imported omeprazole. Conclusion China-made omeprazole is effective and safe in treating acute non-variceal upper gastrointestinal bleeding in comparison with the imported omeprazole.
目的 探討胃切除術后近期上消化道大出血的原因及再手術治療。 方法 對我院1986~2002年間收治的14例胃切除術后近期（24～72 h內）上消化道大出血行再手術治療的病例資料進行回顧性分析。 結果 本組14例，術后吻合口出血4例，殘胃粘膜損傷出血2例，殘胃腸套疊出血2例，十二指腸殘端出血1例，遺漏十二指腸球后潰瘍及賁門粘膜撕裂出血各1例，原因不明出血3例，均經再次手術治療后痊愈。 結論 胃切除術后近期上消化道大出血原因多為操作不當及病灶遺漏所致，出血灶直視下縫扎為有效止血方法。
From 1984 to 1994, 196 patients with massive upper gastrointestinal hemorrhage (hemorrhagic gastritis 137 cases, gastric ulcer 59 cases) caused by acute gastric mucosal lesions were treated in our hospital. As soon as the diagnosis was established, the stress factors in relation to acute gastric mucosal lesions and the factors damaging gastric mucosal barrier should he dispeled and hypovolemia should he corrected. In this group, the operative mortality were as follow: stress ulcer 6.3%, hemorrhagic gastritis 33.3%. According to this result, we consider that in cases of hemorrhagic gastritis the surgical operation must be considered with great care, but for stress ulcer with massive bleeding energetic surgical operation should be taken.
