Methods: Seventyone cases above 60 years with Obstructive Colorectal Cancer were analysed retrospectively on their individual accompanied diseases and perioperative treatments, from 2003 to 2008.Results: Fortythree cases of them had suffered from other diseases. Midoperative complications occurred in 19 cases. Postoperative complications occurred in 37 cases. Except 5 cases of death, complications occurring in others cases were well controlled. The death causes mainly were correlated with accompanied chronic diseases. Conclusion: Strengthen care, active management of other chronic diseases are important significantly for senile patients with colorectal carcinoma to get satisfied outcome.
Objective To analyze the effect of meglumine diatrizoate on diagnosing and treating adhesiveness small intestinal obstruction. Methods The clinic data of 484 cases of adhesiveness small intestinal obstruction were analyzed retrospectively. Those patients were treated with radiography with 76% of meglumine diatrizoate by orally or injected. Results After taking meglumine diatrizoate, 362 patients were cured, and the other 122 cases were diagnosed clearly and treated with surgery. Conclusions Meglumine diatrizoate can be used to diagnose adhesiveness small intestinal obstruction and confirm where the obstruction is. It can be the routine treatment for adhesiveness small intestinal obstruction and can be used repeatedly. It also can provide evidence to surgical treatment and guide to make the surgical project.
To evaluate the possibil ity of collateral outflow tract of arterial sclerosis obstruction （ASO）and the prospect of cl inical appl ication. Methods The red emulsion was infused into the arteries of the above knee amputation of 10 fresh specimens. Then the pathological changes of the anterior tibial artery, posterior tibial artery and the popl iteal artery, and the contribution of these bole artery branch were observed. From September 2005 to April 2007, 5 patients with ASO were treated, unilateral lower l imb was involved in all cases. There were 3 males and 2 females, aged 68-81 years. The arteriography and Color Doppler ultrasound of lower l imbs showed that the femoral artery and the popl itealartery and the branches had no development. The exploratory operation on the popl iteal artery and the branches was carried out. Results The walls of the anterior tibial artery, posterior tibial artery, and the popl iteal artery were stiff and the lumens were filled with atheromatous plaque. The sural arteries opening to the bole artery was frequent. The collateral circulation at the knee perimeter was raritas rather affluent at the muscle group. All of the operations were successful, the skin temperature increased gradually after operation, and the degrees of blood oxygen saturation increased to 90%-100% at 6 hours from 0 before operation . After a follow-up of 3 to 12 months, the symptom improved obviously, rest pain disappeared, lower l imb ulcer healed. The Color Doppler ultrasound showed that most of the blood flow at the anastomotic stoma ejected into bypass circuit, and the blood flow at the distally posterior tibial artery and anterior tibial artery was l ittle. Conclusion The collateral outflow tract construction is feasible, it is an effective path after cl inical verification to solve the advanced stage ASO
Objective To explore the clinical effects of ileus tube in treatment of colonic obstruction caused by colorectal carcinoma. Methods Thirtytwo colorectal carcinoma patients with colonic obstruction admitted to our hospital from December 2005 to December 2008 were given onestage radical excision and anastomosis after transnasal or transanal placement of ileus tube for colonic decompression and drainage. Results Combined placement of transnasal and transanal ileus tube was successfully carried out in 19 cases, while the other 13 cases were treated only with transnasal ileus tube. Abdominal pain and distention of all cases were relieved 12-36 h after tube placement, while those of 26 cases disappeared 48-96 h later. Compared with before tube placement, abdominal circumferences of all cases were significantly reduced after tube placement, the mean reduction rate was (81.3±19.6)% vs. 100% (t=3.586, P=0.02). All cases were successfully treated by onestage radical excision and anastomosis 5-7 d after placement, and no serious complications such as peritoneal infection, anastomotic leakage etc. were found. Conclusion Preoperative intubation of ileus tube can enhance the therapeutic effects of onestage radical excision and anastomosis in patients with colorectal carcinoma combined with colonic obstruction.
One hundred and twenty eight patients with intestinal obstruction due to cancer of left lemicolon are presented. In this series 71 patients suffered from partial intestinal obstruction and 57 patients from complete obstruction, the latter were in later Dukes stages, with lesser resectability of the tumor and higher mortality. The transition from partial obstruction to complete obstruction takes a slow course. Purgatives and coarse fibered food should not be given to the patients with partial obstruction, or else will induce acute obstruction. Several types of operation for partial and complete obstruction are discussed. Methods and results of intraoperative colonic irrigation are presented. The authors believe that intraoperative colonic irrigation is a good emergency management for cancer obstruction of the left colon. Complication of this disease are also discussed.
Coronary artery obstruction is a rare but fatal complication of transcatheter aortic valve replacement. Although there is no accepted criteria to fully evaluate the occurrence of coronary artery obstruction, studies have revealed many important risk factors, and some preventive measures have also been found to reduce their occurrence. At present, transcatheter aortic valve replacement is in a stage of rapid development in China, but clinical medical workers’ knowledge of coronary artery obstruction as a complication still needs to be improved. This article discusses the incidence, risk factors, predictive assessment, prevention, treatment and prognosis of coronary artery obstruction complicated by transcatheter aortic valve replacement, so as to increase clinical medical workers’ understanding of this complication.
Objective To compare the clinical effects of one-stage anastomosis on patients with middle and lower rectum carcinoma and intestinal obstruction and the ones without intestinal obstruction, and to evaluate the safety and feasibility of patients with middle and lower rectum carcinoma and intestinal obstruction undergoing one-stage anastomosis. Methods The data of patients diagnosed definitely by pathology as middle and lower rectum carcinoma underwent one-stage anastomosis in West China Hospital of Sichuan University between January 2007 and December 2008 was retrospectively analyzed. The clinical effects were compared between intestinal obstruction group and non-intestinal obstruction group. Results During this period, 525 patients were included into intestinal obstruction group (n=87) and non-intestinal obstruction group (n=438). Among the patients included, there were 307 males and 218 females. Ages were from 25 to 85 years, and the average age was 60 years old. According to tumor histology, there were 487 cases of adenocarcinoma, 29 of mucinous adenocarcinoma and 9 of other types. According to the degree of tumor differentiation, there were 140 cases of low differentiation, 372 of middle differentiation and 13 of high differentiation. According to TNM stage, there were 4 cases of stage 0, 93 of stageⅠ, 189 of stage Ⅱ, 202 of stage Ⅲ and 37 of stage Ⅳ. Constituent ratio of gender, distributions of distances from tumor to anus, TNM stages and differentiation degrees of tumor were significantly different between intestinal obstruction group and non-intestinal obstruction group (Plt;0.05); and there was no statistical difference in the age, pathological types， significant internal medical complications and operative types between the two groups (Pgt;0.05). There was no statistical diffe rence in operative duration and intraoperative blood loss between the two groups (Pgt;0.05). There was no statistical difference in postoperative time of first defecation, first out-of-bed activity and first oral feeding, and postoperative hospital stay between the two groups (Pgt;0.05); while time of first aerofluxus was earlier in intestinal obstruction group than that in non-intestinal obstruction group (Plt;0.05). There was no statistical significance in the disease incidence of postoperative complications between the two groups (Pgt;0.05). Conclusions Comparing with patients with non-intestinal obstruction, there is no significant evidence shows that one-stage anastomosis will affect the rehabilitation and increase the risk of complications in patients with middle and lower rectum carcinoma and intestinal obstruction. It is considered that it would be safe and feasible for patients with middle and lower rectum carcinoma and intestinal obstruction to have one-stage anastomosis; however, it is necessary for us to have more researches to evaluate the long-term clinical effect.
ObjectiveTo compare the therapeutic efficacy of biliary tract stent placing for malignant obstruction of biliary tract by percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiography (ERC). MethodsPTC approach: choosing the expansion intrahepatic bile duct which had a large angle traveling with common bile duct at the ultrasound-guided, we performed bile duct puncture and inserted the drainage pipe into it, then stent was placed with 68 cases (2 cases among the total were failure of ERC approach) after a week drainage. ERC approach: inserting drainage tube into the common bile duct by duodenal endoscopic retrogradely, the angiography showed obstruction site, the guide wire inserted through the obstruction site, then stent was placed along the guide wire with 53 cases. ResultsThe achievement ratio of stent placing by PTC was 100%(68/68), and which by ERC was 96.2%（51/53）. The complications (bleeding, bile leakage) didn’t happen in two groups. 1-18 months (average 12.4 months) of follow-up, the died cases of PTC group and ERC group were 7 and 5 cases within 6 months, respectively; the survive cases of which were 17 and 9 cases after 18 months of treatment, respectively. ConclusionsThe biliary tract stent placing is a safe and effective method to the malignant obstruction of biliary tract patients who can not drainage tube be treated by operation. It can relieve biliary obstruction efficiency, and can increase live time and life quality for patients. We can choose the stent placing method by ERC for cases whose obstruction site is at the inferior of common bile duct or duodenal ampulla, and the cases whose obstruction site is at the above of hepatic porta should be chosen by PTC.
ObjectiveTo explore the composition of intestinal microbiota between patients with fixed airflow obstruction asthma, reversible airflow obstruction asthma, and healthy control, and analyze the correlation between key differential bacterial distribution and clinical characteristics. MethodsFifteen patients with fixed airflow obstruction asthma (FAO) and 13 patients with reversible airflow obstruction asthma (RAO) were included, along with 11 matched healthy control subjects. Clinical data were collected, and lung function tests and induced sputum examination were performed. Blood and stool samples were tested to compare the gut microbiota status among the groups, and analyze the relationship between gut microbiota abundance and patients' blood routine, IgE levels, lung function, and induced sputum. Results The dominant bacterial compositions were similar in the three groups, but there were differences in the abundance of some species. Compared to the RAO group, the FAO group showed a significant increase in the genera of Bacteroides and Escherichia coli, while Pseudomonas was significantly decreased. The phylum Firmicutes was negatively correlated with the course of asthma, while the phylum Bacteroidetes and genus Bacteroides were positively correlated with the asthma course. Bacteroidetes was negatively correlated with Pre-BD FEV1/FVC, Pseudomonas was positively correlated with Pre-BD FEV1, Escherichia coli was negatively correlated with Post-BD FEV1/FVC, and Bacteroides was negatively correlated with Post-BD MMEF. The class Actinobacteria and the order Actinomycetales were negatively correlated with peripheral blood EOS%, while the order Enterobacteriales and the family Enterobacteriaceae were positively correlated with peripheral blood IgE levels. Furthermore, Actinobacteria and Actinomycetales were negatively correlated with induced sputum EOS%. Conclusions There are differences in the gut microbiota among patients with fixed airflow obstruction asthma, reversible airflow obstruction asthma, and healthy individuals. Bacteroides and Escherichia coli are enriched in the fixed airflow obstruction asthma group, while the Firmicutes are increased in the reversible airflow obstruction asthma group. These three microbiota may act together on Th2 cell-mediated inflammatory responses, influencing the process of airway remodeling, and thereby interfering with the occurrence of fixed airflow obstruction in asthma.
Objective To array the small intestine so that the uncontrollable adhesions will turn to controllable abhesions in order to prevent the intestinal obstruction. Methods Literatures were reviewed. The advance of plication of small intestine has passed through three stages: 1st, sewing the intestine just like the array of harpsichord keys; then, using straight needle with coarse threads to make a ‘U’ suture for the mesentery of small intestine so the intestine was arrayed, and 3rd inserting a Millers-Abbott tube into the lumen of small intestine followed by manual arrangement of the intestine. Results Using the Millers-Abbott tube the intestine was fixed in a steady position and arrayed in a half moon circular shape to avoid sharp angle. As a result, the intra-luminal pressure of the intestinal was effectively decreased. Follow up 45 cases showed the cure rate of 91.9%. Conclusion This operation has widely been accepted by the surgeons for its simplicity, high efficacy and reliability. It reduces the recurrence rate of adhesive obstruction.
