The incidence of postoperative excessive bleeding and reexploration is relatively high, and it will bring a series of serious complications, such as an additional surgery, a longer intensive care unit stay, longer time on mechanical ventilation, an increase need of allogeneic blood product transfusions and increased mortality. However, the understanding of postoperative excessive bleeding and reexploration in China is significantly different from the international level, and the understanding of postoperative excessive bleeding and reexploration after cardiac surgery in clinical work is still not enough. This review will focus on some problems, such as related factors analysis of postoperative excessive bleeding, hemostatic process optimization and the serious complications of reexploration after cardiac surgery.
【Abstract】 Objective To evaluate the detection and localization of obscure lower gastrointestinal bleeding by using SPECT/CT and intraoperative endoscopy. Methods Twenty-six cases of patients with obscure lower gastrointestinal bleeding were analyzed retrospectively. Results The positive detection rate of SPECT/CT was 88.5%. All 26 patients (100%) were identified the bleeding source by using intraoperative endoscopy. No recurrence was found during 1-24 months follow-up. Conclusion SPECT/CT examination should be chosen firstly for patients with obscure lower gastrointestinal bleeding in order to localize the bleeding site roughly. Intraoperative endoscopy can localize the bleeding site accurately in patients who undergoes operation.
Objective To evaluate the efficacy and safety of mifepristone for perimenopause dysfunctional uterine bleeding (PDUB). Methods Such databases as VIP, CNKI, Wanfang and CBM were retrieved for collecting randomized controlled trials (RCTs) on mifepristone for PDUB. The quality of included studies was evaluated and Meta-analysis was performed according to the Cochrane methods. Results Forty RCTs involving 3 850 PDUB patients were included. The control group was divided into two sub-groups according to the features of intervention drugs: the sub-group of diagnostic curettage plus progestational hormone, and the sub-group of diagnostic curettage plus antiestrogenic drugs. The Meta-analysis indicated that compared with the sub-group of diagnostic curettage plus progestational hormone, the diagnostic curettage plus mifepristone group was more effective to increase the total effective rate, such as improving symptoms and signs of PDUB (RR=1.11, 95%CI 1.06 to 1.16, Plt;0.000 01), and to reduce recurrence (RR=0.44, 95%CI 0.36 to 0.52, Plt;0.000 01). But no differences were found between the two groups in the change of endometrial thickness, contents of hemoglobin, and serum level of FSH, LH, E2 and P hormone. Both the intervention and control groups appeared mild adverse reactions, such as rashes, tidal fever, nausea, anorexia, vomiting and breast distending, but with no liver and kidney damages. The long-term safety failed to be evaluated due to short follow-up time. Conclusion Based on this review, diagnostic curettage plus mifepristone shows certain advantage in the treatment of PDUB including the total effective rate and reducing recurrence. But there is no difference in regulating sex hormone level, inhibiting endometrial proliferation and improving anemia compared with the group of diagnostic curettage plus progestational hormone. However, this evidence is not b enough due to the low quality of included trials, possible bias risk, and failure of evaluating its long-term safety.
ObjectiveTo discuss the effect of glucosamine-hydrochloride (Glu/Ch) in protecting and repairing the cartilage in blood-induced joint damage (BJD) in vivo. MethodsThirty-two adult New Zealand rabbits were randomly divided into 4 groups (n=8):high-dose Glu/Ch treated group (group A), low-dose Glu/Ch treated group (group B), positive control group (group C), and negative control group (group D). A joint bleeding model was established by blood injection into articular cavity in groups A, B, and C. Glu/Ch was given by gavage in groups A (250 mg/kg) and B (21.5 mg/kg) once a day for 8 weeks, and the same dosage of saline was given in groups C and D. The serum cartilage oligomeric matrix protein (COMP), serum chondroitin sulfate 846(CS846), and urinary C-terminal telopepide of type II collagen (CTX-II) were measured at 3 days, 7 days, 2 weeks, and 8 weeks after modeling. The expressions of cytokines such as interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) in synovial fluid were analyzed by ELISA at 8 weeks after modeling. The expression of matrix metalloproteinase 13(MMP-13) was detected by immunohistochemistry. Alcian blue staining and Safranin-O staining were performed to calculate the percentage of the positive staining areas. The proteoglycan content was detected by semi-quantitative analysis in the articular cartilage. ResultsThe COMP concentration was significantly higher in groups A, B, and C than group D, and in groups B and C than group A at 3 days after modeling (P<0.05); no significant difference was found among groups A, B, and D at 7 days (P>0.05), and it was significantly lower in groups A, B, and D than group C (P<0.05); there was no significant difference among 4 groups after 2 and 8 weeks (P>0.05). Difference in CS846 concentration had no significance among 4 groups at each time point (P>0.05). The CTX-II concentration of groups A, B, and C was significantly higher than that of group D at each time point (P<0.05); it was significantly lower in group A than groups B and C at 7 days, 2 weeks, and 8 weeks (P<0.05). The TNF-α concentration of groups A and B was significantly higher than group D, and was significantly lower than group C at 8 weeks (P<0.05), but no significant difference was observed between groups A and B (P>0.05). The IL-1β concentration was significantly higher in group C than the other groups (P<0.05), and in group B than groups A and D (P<0.05), but there was no significant difference between groups A and D (P>0.05). The MMP-13 expression was significantly higher in group C than groups A, B, and D (P<0.05), in groups A and B than group D (P<0.05). A significant decrease in the area stained with Alcian blue and Safranin-O was observed in group C. There were significant differences in the percentage of the positive stained areas of Alcian blue and Safranin-O among 4 groups (P<0.05). The relative quantities of proteoglycan from small to large in order was groups C, B, A, and D, respectively, showing significant differences (P<0.05). ConclusionThe metabolism disorder of cartilage matrix and synovium inflammatory reaction can be observed in rat joint bleeding model. Glu/Ch has certain protective effect on the cartilage after BJD by down-regulating IL-1β, TNF-α, and MMP-13, as well as increasing proteoglycan content in the cartilage.
Objective To analyze the difference in the incidence of postoperative pancreatic leakage and anasto-motic bleeding complications in various methods of pancreaticojejunostomy after pancreaticoduodenectomy （PD）. Methods The clinical data of 526 patients underwent pancreaticojejunostomy from January 2008 to September 2012 in this hospital were analyzed retrospectively. End-to-side “pancreatic duct to jejunum mucosa-to-mucosa” anastomosis （abbreviation：mucosa-to-mucosa anastomosis） was performed in 359 patients， which contained 149 patients with internal drainage， 130 patients with external drainage， and 80 patients with no drainage. End-to-side invaginated anastomosis was performedin 165 patients without drainage. In addition， side-to-side anastomosis was performed in 2 patients without drainage.Results There were 34 cases （6.46%） of pancreatic leakage， 8 cases （1.52%） of anastomotic bleeding in pancreaticoje-junostomy， and 32 cases of death （6.08%）. ① The pancreatic leakage rate of mucosa-to-mucosa anastomosis was signi-ficantly lower than that of end-to-side invaginated anastomosis 〔4.18% （15/359） versus 11.52% （19/165）， χ2=10.029， P=0.002〕. There was no significant difference of the anastomotic bleeding incidence between mucosa-to-mucosa anasto-mosis and end-to-side invaginated anastomosis 〔1.67% （6/359） versus 1.21% （2/165）， χ2=0.159， P=0.691〕. ② In the mucosa-to-mucosa anastomosis group， the pancreatic leakage rates in the ones with internal drainage and external drainage were lower than those in the ones without drainage， respectively （2.68% （4/149） versus 11.25% （9/80）， χ2=7.132， P=0.008；1.54% （2/130） versus 11.25% （9/80）， χ2=9.410， P=0.002）；which was no significant difference between the ones with internal drainage and external drainage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕. But there were no significant differences for both the pancreatic leakage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕and anastomotic bleeding incidence 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕 between the ones with internal drainage and external drainage. Conclusions Mucosa-to-mucosa anastomosis has a lower pancreatic leakage incidence as compared with end-to-side invaginated anastomosis. However， there is no significant difference of the anast-omotic bleeding incidence. Internal or external drainage could reduce the incidence of pancreatic leakage， but have no obvious effect to the anastomotic bleeding incidence.
ObjectiveTo investigate the relationship between chronic obstructive pulmonary disease (COPD) and respiratory failure in patients with upper gastrointestinal bleeding and recent prognosis. MethodsWe retrospectively analyzed the clinical data of 73 patients with COPD and respiratory failure treated from February 2009 to May 2011. The patients were assigned to the observing group (n=33) and control group (n=40). General characteristics, improvement rates, mortality rates, lengths of hospital stay, endotracheal tube rates and arrhythmia rates were compared between the two groups. ResultsAge, sex, and medical history of the patients were similar in both groups (P>0.05). Compared with the control group, the improvement rate was lower (P<0.001), the mortality rate (P<0.001), length of hospital stay (P<0.001), endotracheal tube rate (P<0.05) and arrhythmia rate (P<0.05) were all higher in the observing group after treatment. ConclusionUpper gastrointestinal bleeding is a high risk factor for short-term prognosis patients with COPD and respiratory failure.
Objective To investigate the effect of emergency fast-track treatment on dangerous upper gastrointestinal bleeding. Methods Seventy-six patients who received traditional treatment between October 2020 and March 2021 were included in the traditional treatment group, and 82 patients who entered the emergency fast track for dangerous upper gastrointestinal bleeding between April 2021 and September 2021 were included in the fast-track treatment group. The patients in the traditional treatment group were treated with the traditional single-subject diagnosis and treatment mode, and the patients in the fast-track treatment group were treated according to the multidisciplinary diagnosis and treatment procedures of emergency fast track for dangerous upper gastrointestinal bleeding. The length of emergency stay, 24-hour endoscopic completion rate, effective rate, and length of hospital stay were compared between the two groups. Results The length of emergency stay [(3.75±3.19) vs. (6.51±4.72) h], the effective rate (96.3% vs. 85.5%) and the length of hospital stay [(8.26±2.51) vs. (11.07±2.79) d] were significantly better in the fast-track group than those in the traditional treatment group (P<0.05). There was no significant difference in the 24-hour endoscopic completion rate between the two groups (96.3% vs. 96.1%, P>0.05). Conclusion Compared with the traditional treatment mode, the fast-track treatment mode can significantly improve the treatment efficiency, and reduce the lengths of emergency stay and hospital stay.
ObjectiveTo investigate the clinical value of laparoscopic cholecystectomy following “A-B-D” approach applied in the operation of acute suppurative or gangrenous cholecystitis.MethodsWe sought out 45 patients diagnosed as acute suppurative or gangrenous cholecystitis and treated by laparoscopic cholecystectomy following the “A-B-D” approach in People’s Hospital of Leshan from Sep. 2019 to Dec. 2020 as the observation group (ABD observation group), and sought out 50 patients with the same diseases but treated by conventional laparoscopic cholecystectomy from Jun. 2018 to Aug. 2019 as the matched group (conventional matched group). We analyzed and compared the parameters related to safety and efficacy of the two groups retrospectively.ResultsA total of 95 patients were included, including 45 patients in the ABD observation group (26 cases of acute suppurative cholecystitis, 19 cases of acute gangrenous cholecystitis) and 50 patients in the conventional matched group (24 cases of acute suppurative cholecystitis, 26 cases of acute gangrenous cholecystitis). There were no significant differences in age, gender, body mass index, disease composition, gallbladder condition, and preoperative complications between the two groups (P>0.05). There was no bile duct injury case in the ABD observation group (0), while there were 4 cases (8.0%) in the conventional matched group, but the statistical results showed no statistical significance between the two groups (P=0.054). One case (2.2%) in the ABD observation group converted to laparotomy, which was significantly lower than the 10 cases (20.0%) in the conventional matched group, and the difference was statistically significant (P=0.017). In addition, there were no significant differences for other parameters including operative time, postoperative hospital stay, incidences of intraoperative bleeding and postoperative bleeding between the two groups (P>0.05).ConclusionsThe laparoscopic cholecystectomy following the “A-B-D” approach can help distinguish the anatomical structure of cystic duct and extrahepatic bile duct clearly, and it can help prevent biliary tract injury effectively and reduce the probability of conversion to laparotomy. It is worthy of clinical application and promotion, especially in the majority of county hospitals.
Objective To assess the clinical efficacy and safety of proton pump inhibitor （PPI） and H2RA for stress ulcer bleeding in stroke patients. Methods Randomized controlled trials （RCT） were identified from MEDLINE （ 1966- Oct. 2005 ） ,EMBASE （ 1984- Oct. 2005 ）, The Cochrane Library （ Issue 4,2005 ）, CBMdisc （ 1980- Oct. 2005 ） and VIP（ 1980- Oct. 2005 ）. We handsearched the related published and unpublished data and their references. The quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 4. 2.7 software was used for data analysis. Results Twenty RCT were included with 2 624 patients. The results of meta-analysis were listed as follows： （1） stress ulcer bleeding （SUB） ： PPI （ OR 0.14,95% CI 0.08 to 0.24, NNT = 3 ） and H2RA （OR 0.24,95% CI 0.15 to 0.39, NNT =5） significantly reduced the incidence of SUB in comparison with control group. PPI significantly reduced the incidence of SUB compared with H2R.A（P 〈0. 00001 ）. （2） Mortality： PPI （OR 0.22,95% CI 0. 11 to 0.47, NNT =8） and H2RA （OR 0.53,95% CI 0. 34 to 0.81, NNT =16） significantly decreased the mortality compared with non-prophylaxis group. PPI significantly decreased the mortality compared with H2RA （OR 0.28,95% CI 0.09 to 0. 89）. （3） Adverse effect： There were not evident adverse effects in both PPI and H2RA groups. Conclusions PPI and H2RA may reduce the incidence and mortality of SUB in stroke patients, and PPls are better in reducing incidence of SUB than H2RA.
Severe trauma is a challenging medical problem. Uncontrolled post-traumatic hemorrhage and traumatic coagulation dysfunction are closely related to the prognosis of these patients. In May 2019, the pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma published the fifth edition of the European guideline on management of major bleeding and coagulopathy following trauma. To assist Chinese in better understanding of the latest developments, this paper translated the main treatment recommendations in the guideline and interpreted the updated content from the fourth edition.
