RESUMEN
ObjectiveTo investigate the risk factors for open pancreatic necrosectomy (OPN), an effective treatment method for severe acute pancreatitis (SAP) after the failure of percutaneous catheter drainage (PCD), in patients with SAP. MethodsA retrospective analysis was performed for 156 patients with SAP who underwent surgical intervention based on the step-up approach in The Affiliated Hospital of Zunyi Medical University from January 1, 2010 to June 30, 2018, and according to whether OPN was performed, the patients were divided into PCD group with 126 patients and PCD+OPN group with 30 patients. Related clinical data were collected, including age, sex, etiology, blood calcium on admission, white blood cell count on admission, whether CTSI score was ＞7, APACHE-Ⅱ score, Ranson score, presence or absence of peripancreatic fluid accumulation, presence or absence of infection, presence or absence of multiple organ failure (MOF), and whether PCD was performed at more than 1 week after admission. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; a multivariate logistic regression analysis was used to determine the independent predictive factors for OPN. ResultsThe probability of OPN was 19.2% for SAP patients in the later stage. Compared with the PCD+OPN group, the PCD group had a significantly lower proportion of patients with MOF on admission ［27.0% (34/126) vs 70.0% (21/30), χ2=19.642, P＜0.01］ and a significantly higher proportion of patients undergoing PCD at less than 1 week after admission ［61.9% (78/126) vs 20.0% (6/30), χ2=17.121, P＜0.01］. MOF on admission (odds ratio ［OR］=5.343, 95% confidence interval ［CI］: 1.832-15.583, P＜0.05), initial PCD performed at more than 1 week after admission (OR= 5.518, 95% CI: 1.742-17.477, P＜0.05), and infection on admission (OR=5.016, 95% CI: 1.322-19.378, P＜0.05) were independent risk factors for subsequent OPN in SAP patients. ConclusionSAP with MOF on admission, initial PCD performed at more than 1 week after admission, and SAP with infection on admission are independent risk factors for subsequent OPN in SAP patients undergoing PCD in the early stage based on the step-up approach. Timely identification of related risk factors helps to grasp the timing of OPN in clinical practice and improve the clinical prognosis of SAP patients.
RESUMEN
Robot-assisted laparoscopy hepatectomy (RALH) is a new technique for surgical operation. Compared with conventional laparoscopic hepatectomy, RALH is more frequently used in complex liver tumor and liver tumor with special locations, but this technique is still under development and is limited by the burden of high costs and surgical devices. Meanwhile, there is a lack of generally accepted and confirmed clinical data, and therefore, the role of RALH is still under debate. This article reviews the surgical indication, learning curve, advantages, and limitations of RALH.
RESUMEN
Objective To explore the safety and efficacy of laparoscopic cholecystectomy in different time points after endoscopic retrograde cholangiopancreatography in elderly patients with cholecystolithiasis and choledocholithiasis. Methods 99 elderly patients （≥60 years old）with cholecystolithiasis and choledocholithiasis treated by sequential LC after ERCP in the Department of Hepatobiliary and Pancreatic surgery in our hospital from January 2015 to June 2020 were analyzed. Aocording to different time points after ERCP, LC was divided into experimental group (within 1 day after ERCP) and control group (within 2-7 days after ERCP). The complications were followed up by telephone within 3 months after operation. Results After analysis，the difference between the experimental group and the control group in the total length of hospitalization [(13.0±4.6)d vs ( 15.1±4.4)d] and total hospitalization expenses (38 172.5±12 448.9) vs ( 42 535.4±8 814.6)] was statistically significant (P<0.05). However, there was no significant difference in the conversion rate of LC to laparotomy, the total postoperative complications , the length of hospital stay after LC，the amount of blood loss during LC and the time of LC operation between the two groups(P>0.05). Conclusion For elderly patients with cholecystolithiasis and choledocholithiasis, LC within 1 day after ERCP does not increase the difficulty of operation and postoperative complications，but shortens the hospitalization time, and it is economical and safe at the same time.
RESUMEN
Hepatic ischemia-reperfusion injury (HIRI) is the main cause of liver damage and even multiple organ failure after complex liver surgery.When liver ischemia reperfusion occurs,the non-coding RNAs in the liver tissue is dysregulated and part of the non-coding RNAs with abnormal expression is involved in HIRI regulation.Non-coding RNAs to may be the intervention target for reducing HIRI.This article summarized the types and related functions of non-coding RNAs,the role of different non-coding RNAs in HIRI,and the interconnections between various non-coding RNAs in HIRI.
