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.
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 explore the bacterial translocation of mesenteric lymph nodes （MLNs） of the ileum and the spectrum of bacteria in patients with small bowel obstruction.Methods Total 84 patients were divided into study group （with small bowel obstruction） and control group （without small bowel obstruction）. MLNs were obtained under sterile conditions intraoperatively， and which were processed for culture of aerobic and anaerobic organisms. The rate of bacterial translocation and postoperative infection were compared between two groups and the species of bacterial translocation was identified. Results The bacterial translocation rate in the study group was higher than that in the control group 〔57.1% （24/42） versus 16.7% （7/42），χ2=14.775， P＜0.01〕. Escherichia coil was the most commonly bacteria （20）. Emergency surgery and age over 70 years were associated with bacterial translocation （P＜0.05）. Postoperative infection complications rate in the bacterial translocation patients was higher than that in the patients without bacterial translocation 〔29.0% （9/31） versus 3.8% （2/53），χ2=10.965，P＜0.05〕. Conclusions Bacterial translocation to MLNs occurres more frequently in patients with small bowel obstruction，non-elective surgery， and elderly.
Objective To analyze risk factors for pulmonary vein obstruction (PVO) after intracardiac total anomalous pulmonary venous connection (TAPVC) repair. Methods A retrospective analysis of clinical data of the patients with intracardiac TAPVC who underwent surgery at our center from April 2009 to April 2019 was conducted. Kaplan-Meier curves were used to assess the risk of postoperative PVO. Logistic regression analysis was used to identify relevant risk factor for postoperative PVO. ResultsWe finally included 169 patients. The median age at surgery was 89.0 (41.5, 195.0) days, and the median weight at surgery was 4.8 (3.8, 6.0) kg. The preoperative PVO rate was 18.3% (31/169). Post-repair PVO occurred in 8.9% (15/169) of the patients. The atresia of common pulmonary and subtype of coronary sinus/right atrium did not significantly affect the risk of PVO (P=0.053, P=0.330). Relevant risk factors included preoperative PVO (P<0.001) and the ratio of left ventricular end-systolic diameter to right ventricular diameter (P=0.025). ConclusionSurgical repair of intracardiac TAPVC has achieved satisfactory results in our center, but the long-term risk of obstruction should not be underestimated. An increased ratio of left ventricular end-systolic diameter to right ventricular diameter and preoperative PVO are associated with post-repair PVO.
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 outcomes of sutureless technique and conventional technique in the surgical repair for infracardiac total anomalous pulmonary venous connection (TAPVC).MethodsThe clinical data of 46 consecutive patients with infracardiac TAPVC undergoing surgical repair in our hospital between June 2014 and April 2019 were retrospectively analyzed. Patients with combined congenital cardiac anomalies such as single ventricle and tetralogy of Fallot were excluded. Patients were divided into a conventional technique group and a sutureless technique group according to the surgical techniques. There were 35 patients in the conventional technique group, including 28 males (80.0%) and 7 females (20.0%) with a median age of 21 (8, 42) d and a median weight of 3.6 (3.0, 4.0) kg. There were 11 patients in the sutureless technique group, including 8 males (72.7%) and 3 females (27.3%) with a median age of 14 (6, 22) d and a median weight of 3.5 (2.9, 3.6) kg. The curative effect of the two groups was compared.ResultsThere were 5 deaths (10.9%) in the conventional technique group, including 4 in-hospital deaths (8.7%) and 1 late death (2.2%). Overall mortality of the conventional technique group (14.3%, 5/35) was higher than that of the sutureless technique group (0.0%, 0/11), although the difference was not statistically significant (P=0.317). Cox regression analysis showed that sex (P=0.042), age at repair (P=0.028), cardiopulmonary bypass time (P=0.007), aortic cross-clamping time (P=0.018) and duration of ventilation (P=0.042) were risk factors for postoperative mortality. The median follow-up was 18.00 (5.00, 37.75) months. Postoperative pulmonary venous obstruction occurred in 22 patients of the conventional technique group, which was significantly more than that of the sutureless technique group (P=0.000).ConclusionFor infracardiac TAPVC, sutureless technique can reduce the incidence of postoperative pulmonary venous obstruction compared with conventional technique.
To investigate the mechanisms of hepatic injury after biliary obstruction. After a rat model of complete biliary obstruction(CBO) was induced, hepatocyte mitochondria was isolated and the calcium content of mitochondria, the contents of liver malondialdyhyde (MDA) and superoxide dismutase (SOD), the levels of serum T-Bil, ALT, ALP and GGT were measured in each group. Results: After CBO, mitochondrial calcium content, liver MDA and serum T-Bil, ALT, ALP, GGT became increased progressively, compared with control group (Ｐ＜0.05); the liver SOD was decreased markedly (Ｐ＜0.05). Mitochondrial calcium content was highly positively correlated with liver MDA content, serum ALT and ALP, r values were 0.967, 0.924 and 0.919 respectively (Ｐ＜0.01). The liver MDA content was highly positively correlated with serum ALT and ALP, r values were 0.949 and 0.843 respectively (Ｐ＜0.01). Conclusions: Mitochondrial calcium overload and liver lipid peroxidation may be the important mechanisms of hepatic injury induced by biliary obstruction.
OBJECTIVE To sum up the experience of diagnosis and treatment of intrinsic upper gastro-intestinal membrane, 13 cases in children were studied retrospectively. METHODS There were 10 boys and 3 girls, the major symptoms were vomiting and epigastric distension. Eleven cases were treated by membranectomy with intestinal plasty, and 2 cases were treated by retrocolic side to end duodenojejunostomy. RESULTS All cases had good results without severe complications. CONCLUSION The children who have typical symptom of upper digestive tract should be considered duodental and upper jejunal membrane, and should be proved by contrast radiology. The membranectomy with intestinal plasty is the better operative method.
ObjectiveTo study the effect of octreotide on acute adhesive intestinal obstruction． MethodsFifty-two patients with adhesive intestinal obstruction from January 2009 to January 2011 in this hospital were divided into octreotide treatment group (n=28) and routine treatment group (n=24) according to the treatment methods. Apart from routine treatments, octreotide was administrated in the octreotide treatment group while traditional treatment in the routine treatment group．The effectiveness was observed and compared between two groups. ResultsThe cure rate of the octreotide treatment group was significantly higher than that of the routine treatment group (Plt;0.05). The anus exhausting and defecating time was earlier, hospitalization time was shorter, and gastrointestinal decompression of the treatment octreotide group as compared with the routine treatment group (Plt;0.05)． ConclusionConventional therapy combining with intravenous infusion of octreotide in patients with acute adhesive intestinal obstruction can improve the clinical symptoms and success rate of treatment．
ObjectiveTo explore the forensic pathology features of foreign body and its emergency treatment: Heimlich maneuver. MethodsWe carried out a review of relevant literature and autopsy findings of 8 cases of foreign body suffocation at West China Forensic Identification Center of Sichuan University from 2000 to 2012. ResultsThe most common foreign body reported was undigested food. Children, old people and middle-aged men who were drunk were vulnerable to choking. The most effective resuscitative procedure in such cases was Heimlich maneuver, but it had been noted to result in significant intra-abdominal and intra-thoracic injuries if performed incorrectly. ConclusionIt is necessary to take some preventive measures to avoid the foreign body, and the publicity of Heimlich maneuver to reduce the incidence and mortality of foreign body is important.
