Surgical treatment of spontaneous rupture of esophagus / 中华创伤杂志

Objective To investigate the effect of the modified surgery for spontaneous rupture of esophagus (SRE) so as to improve treatmeut level.Methods Clinical data and surgical methods of 16 SRE patients including four patients with mid-esophagus ruptures and 12 with lower esophagus ruptures treated between February 1999 and June 2011 were analyzed retrospectively.All patients had only one laceration with the gap length of 1.5-5 cm (median 2.5 cm).Eleven patients had rupture into the left breast,two had rupture into the right chest,with no rupture into the chest in three patients.Ten patients suffered from hydropneumothorax and five from subcutaneous emphysema.Thc esophageal mucosas rathcr than muscular layers of all patients were sutured disconnectedly with absorbable thread.Omentum majus were embedded and fixed to muscular layer on the edge of esophagus rupture site.Fundus ventriculi were suspended and fixed to the dome of diaphragm.In the meantime,diaphragmatic hiatus were reconstructed above the esophagus rupture site for lower esophagus ruptures.Results The time from SRE attack to operation ranged from one hour to three days.Eleven patients were repaired within 24 hours of SRE onset and five patients were repaired after 24 hours of SRE onset.All patients got through the perioperative period smoothly and survived the operation with cure rate of 100％.The median hospital stay was 18.5 days.No esophageal narrow or canceration were found during follow-up (range,1-10 years),but two patients suffered from reflux which were relieved significantly after conservative treatment.Conclusion For treatment of SRE,interrupted suture for esophageal mucosal layers,omentum majus embedding instead of esophageal muscular layer suture and simultaneous anti-reflux operations can significantly reduce incidence of complications like esophageal fistula,stenosis and reflux and improve the cure rate.

Diagnosis and timely treatment for spontaneous rupture of esophagus / 中国医师杂志

Objective To explore the diagnostic approach and the idea of timely treatment for the spontaneous rupture of the esophagus (SRE) for improvement of the level of clinical diagnosis and treatment.Methods The relative clinical data and operation method of 16 cases SRE (4 cases of midpiece SREs and 12 cases of lower SRE) collected from February 1999 to June 2011 were analyzed retrospectively.There were one place breach in 16 cases of SRE with a broken length of 1.5 ～5 cm (2.6 ± 1.1 )cm,including 11 cases broken into the left breast,2 into right chest,and 3 no chest broken into.The main symptoms included intense thoracoabdominal pain,fever,difficulty in breathing,and shock.Ten cases of hydropneumothorax and 5 cases of subcutaneous emphysema were found with physical examination.Results Eleven cases were repaired within 24 hours and 5 cases were repaired after 24 hours.The esophaguses of 16 cases were sutured disconnectedly by absorbable suture line,to which omentum majus were sutured and fixed.Improved resisting backflow operation was carried out for 16 cases which got through the perioperative period smoothly and no deaths.There was no esophageal narrow in follow-up visit,otherwise,there were 2 refluxes that relieved significantly through conservative treatment.Conclusions It is the key to treat SRE that early diagnosis and exploration operation through cutting thorax after definite diagnosis,closing broken hole in order to rebuild the alimentary canal on which omentum majus was covered and fixed for the purpose of insuring continuity of digestive tract.

Preoperative diagnosis and operative route of traumatic diaphragmatic rupture / 中国医师进修杂志

ObjectiveTo study preoperative diagnosis and operative route of traumatic diaphragmatic rupture in order to improve postoperative quality of patients' life.MethodsA retrospective analysis was carried out in 63 patients with traumatic diaphragmatic rupture,all that were identified through operation from January 1990 to March 2009.All cases were associated with pneumothorax and/or hemopneumothorax at various degrees.Forty-nine cases complicated with acute peritonitis and 41 cases complicated with hemorrhagic shock.Thirty-seven cases were diagnosed definitely preoperatively,22 cases were found in operations research,4 cases with inefficacious conservation converted to operation.Thoracotomy was performedin 24 cases,laparotomy in 14 cases,combined thoracolaparotomy in 8 cases and thoracotomy plus laparotomy in 17 cases.ResultsFifty-seven cases recovered,6 cases died of hemorrhagic shock (2 cases),pericardial tamponade ( 1 case),acute respiratory failure ( 1 case) and acute renal failure at postoperative 1 week (2 cases).ConclusionDefinite and timely preoperative diagnosis and correct operative approach are striving the rescue time and success and avoiding complication.

Effect of coronary artery bypass grafting on the expression level of nerve-related factor at myocardium in dogs with acute myocardial infarction / 国际外科学杂志

Objective To investigate the effect and significance of early coronary artery bypass grafting (CABG) on the expression level of nerve-related factor at infracted border zone (IBZ) in dogs with acute myocardial infarction (AMI).Methods The anterior descending coronary artery of all thirty dogs randomly assigned into experimental group(n =22) and control group(n =8)were ligated into MI model.The experimental group included those undergoing CABG 1(n =6),2 week(n =4),4 week(n =6)and 6 week (n =6) after MI,and control group(n =2) was established for every experimental group.We detected the local expression level of nerve-related factor such as GAP43 mRNA,NGF mRNA and SYN mRNA at normal myocardium and infracted border zone myocavdium by means of RT-PCR through thoracotomy at eight weeks after surgery.Results Four dogs of every experimental group and all dogs of control group survived to the end of the study.The local expression level of GAP43 mRNA,NGF mRNA and SYN mRNA in control groups was significantly higher than that in normal and experimental groups (P ＜0.01 ).The local expression level of GAP43 mRNA,NGF mRNA and SYN mRNA in 4 and 6 weeks bypass groups was significantly higher than that in normal and 1,2 weeks bypass groups (P ＜0.05).There was no statistically significant the expression level of SYN mRNA among all experimental groups (P ＞ 0.05 ).Conclusions Early CABG surgery for AMI in dogs could lessen the expression level of nerve-related factor and the sympathetic remodelling at IBZ.Especially CABG surgery two weeks after MI could lessen the sympathetic maximacily.

Analysis of 31 cases with ribs fracture combined with delayed hemothorax / 中华全科医师杂志

The clinical data of 31 patients with delayed hemothorax between August 2003 to November 2010 was retrospectively analyzed. All patients had chest pain, difficult breathing in 14 cases (45％), heart rate increased in 19 patients (61％), fever in 16 cases (52％), abdomen pain in 3 patients (10％), and shock in 1 case (3％).Haemothorax was medium to massive and combined with pneumothorax in 9 cases. Twenty one patients received closed chest drainage, 4 recieved chest puncture to eliminate fluid, 5 were treated conservatively, and 1 had surgery for diaphragmatic hernia and hemorrhage.All patients recovered eventually. The key of diagnosis and treatment for delayed hemothorax is to take chest X-ray for patients with rib fractures in 2 to 9 days after chest trauma, and carefully observing the changes of chest signs, breathing, heart rate and body temperature.
