Objective To discuss the technical keypoints of the second-phase diaplasis treatment after Hartmann operation. Methods Twenty-one cases of the second-phase diaplasis operation of Hartmann operation in this hospital from January 2003 to December 2007 were analysed retrospectively. Results In this group, stapler technique was used in 15 cases, anastomotic ring was used in 3 cases, and one-layer suture was used in 3 cases. The time of these operations was between 118 min and 240 min (mean 164 min). Neither stomal leak nor stomal stenosis occurred, acute ileus occurred in 2 cases, and both recovered after the treatments of gastrointestinal decompression, inhibition of secretion digestive juice and reoperation. Acute retension of urine occurred in 1 case after urine catheter removed. The symptoms disappeared after excises of bladder function. These cases were followed up for 3-36 months (mean 20 months). All the patients recovered to normal function of defecation. Conclusion The technical keypoints of the second-phase diaplasis treatment after Hartmann operation are how to find and liberate the end of the distal colon. It will affect the prognosis and the occurrence of complications after this operation.
Objective To investigate the clinical significance of routine application of choledochoscope during operation of biliary duct. Methods The clinical data of 136 patients with the routine application of intraoperative choledochoscope dealing with bile duct diseases in this hospital from October 2003 to July 2009 were analyzed and summarized. Results Intraoperative choledochoscope inspection, taking stones and targeted surgery were performed in 116 cases with extrahepatic and (or) intrahepatic bile duct stones. The taking out rate of extrahepatic bile duct stones was 100% (85/85), the residual stone rates of extrahepatic and intrahepatic bile duct were 0 (0/85) and 22.6% (7/31), respectively, with the total residual stone rate was 6.0% (7/116). By using intraoperative choledochoscope, benign intrahepatic bile duct stricture was found in 13 cases, malignant extrahepatic and intrahepatic bile duct stricture in 8 cases. Four cases of hilar cholangiocarcinoma and 4 cases of common bile duct cancer, 2 cases of lower segment of common bile duct polyp, 3 cases of hepatolithiasis with the left hepatic bile duct carcinoma were diagnosed by biopsy via choledochoscope. Causes were confirmed by applying choledochoscope in 16 patients with obstructive jaundice. The use of choledochoscope with surgical treatment enabled benign and malignant bile duct stricture to achieve good results, without serious complications such as bile duct dilaceration, subphrenic abscess or acute cholangitis. Conclusions Using choledochoscope can tremendously reduce the residual rate of stone in biliary duct surgery, increase the definite diagnosis rate of biliary duct diseases and play a role of reasonable instruction in its treatment options. It has unique advantages in identifying causes of jaundice. It is remarkable that the role of applying choledochoscope to diagnose and cure biliary duct diseases. It should be widely used.
Objective
To investigate the clinical effects and safety differences of open surgery and laparoscopy primary lesion resection combined with D2 lymph node dissection in the treatment of elderly patients with advanced gastric cancer.
Methods
One hundred and forty elderly patients with advanced gastric cancer were chosen and randomly divided into two group including open operative group (70 patients) with primary lesion resection combined with D2 lymph node dissection by open operation and laparoscopic surgery group (70 patients) with primary lesion resection combined with D2 lymph node dissection by laparoscopy; and the operative time, intraoperative bleeding amount, the levels of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of haemoglobin (Hb) after operation, the hospitalization time, the number of lymph node dissection, the survival rate with followed-up and postoperative complication incidence of both groups were compared.
Results
There was no significant difference in the operative time between 2 groups (P>0.05). The intraoperative bleeding amount, the level of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of Hb after operation and the hospitalization time of laparoscopic surgery group were significantly better than open operative group (P<0.05). The level of PaCO2 in operation of laparoscopic surgery group was significantly higher than open operative group (P<0.05). There were no significant difference in the gastric lymph node dissection number and the peripheral lymph node dissection number of gastric artery between 2 groups (P>0.05). There were no significant difference in the survival rates between the 2 groups after 3-year followed-up (P>0.05). The complication incidence after operation of laparoscopic surgery group was significantly lower than open operative group (P<0.05). The quality of life scores of patients in laparoscopic surgery group were significantly higher than those in open operative group on 7 days and in 3 months after operation, and the difference were statistically significant (P<0.05).
Conclusion
Compared with open operation, primary lesion resection combined with D2 lymph node dissection by laparoscopy in the treatment of elderly patients with advanced gastric cancer can efficiently possess the advantages including minimally invasive, shorter recovery time and less postoperative complications.
Objective To evaluate the cl inical outcomes of modified posterior-anterior operation in the treatment of serious lumbar fracture and dislocation. Methods From January 2002 to February 2006, 24 patients, 17 males and 7 females aged 22-69 years, underwent reduction of posterior spatium intermuscular approach combined with modified anterioroperation. Nine cases were caused by fall ing and 15 by traffic accident, involving: L1 in 5 cases, L2 in 10 cases, L3 in 4 cases, L4 in 2 case, L1,2 in 1 case and L3,4 in 2 cases. According to the Frankel grade, there were 5 cases for grade A, 11 for grade B, 7 for grade C and 1 for grade D. The recovery of neurological function was evaluated. The imageology examination was appl ied to evaluate the condition of internal fixation and bone union. The Cobb’s angle was measured by X-ray film before operation, 3 days after operation and at the final follow-up, and the difference was estimated. Results Nineteen patients were followed up for 8-52 months, 28.4 months on average. Among the 2 cases of grade A, one improved to C and the other had no improvement. Among the 9 cases of grade B, 5 improved to C, 2 improved to D, and other two had no improvement. Among the 7 cases of grade C, 5 improved to D and 2 improved to E. One case of grade D improved to E. The average Cobb’s angle was (—11.5 ± 4.6)° preoperatively, (4.2 ± 4.7)° 3 days after operation and (4.0 ± 4.8)° at the final follow-up, indicating there was a significant difference between preoperation, 3 days after operation and the final follow-up (P lt; 0.001), but no significant difference between 3 days after operation and the final follow-up (P gt; 0.05). The position of internal fixation was good during follow-up. The compl ications such as disruption, loosening and collapse were not observed. Conclusion Reduction of posterior spatium intermuscular approach combined with modified anterior operation in the treatment of serious lumbar fracture and dislocation could complete the reduction, decompression, grafting and internal fixation in one stage, and protect the paraspinal soft tissue and minimize the trauma caused by surgery. It has the merits of short time of operation, small amount of intraoperative hemorrhage, sol id union of internal fixation and satisfactory cl inical outcome.
Objective To investigate the clinical significance of intra-abdominal pressure measure in patients with liver transplantation by summarizing the data of 143 cases. Methods Intra-abdominal pressure was indirectly measured by urinary bladder pressure. Intra-abdominal pressure over 10 cm H2O (1 cm H2O=0.098 kPa) was regarded as intra-abdominal hypertension (IAH), and 10＜pressure≤15 cm H2O as gradeⅠ, 15＜pressure≤25 cm H2O as grade Ⅱ, 25＜pressure≤35 cm H2O as grade Ⅲ, over 35 cm H2O as grade Ⅳ. The parameters of circulatory system, respiratory system, renal function and the postoperative intra-abdominal pressure for 7 days were recorded to every patient, and the parameters of each grade IAH group were contrasted with non-IAH group. ResultsAmong 143 cases, 45 cases were IAH (31.5%), in which 18 cases belonged to grade Ⅰ, 13 cases belonged to grade Ⅱ, 11 cases belonged to grade Ⅲ, while 3 cases belonged to grade Ⅳ. Compared with those in non-IAH group, SCr and BUN significantly increased (P＜0.05, P＜0.01), PaO2 significantly decreased (P＜0.05, P＜0.01) in each grade IAH group; Respiratory frequency (RF), heart rate (HR) and PaCO2 significantly increased (P＜0.05, P＜0.01) in some grade IAH group (HR in grade Ⅱ, Ⅲ and Ⅳ, RF and PaCO2 in grade Ⅲ and Ⅳ). Conclusions Intra-abdominal hypertension would affect liver function by impaired circulatory, respiratory and renal function. So, it is necessary to measure intra-abdominal pressure for patients after liver transplantation, which can help to choose appropriate treatment.
Objective To investigate the value of indocyanine green fluorescence imaging in common bile duct reexploration. Methods The clinical data of 32 patients who underwent open common bile duct reexploration in the Affiliated Hospital of Southwest Medical University from January 2018 to December 2020 were collected retrospectively. All patients divided into the control group (conventional exploration group, 20 patients) and the fluorescence imaging group (using indocyanine green fluorescence imaging, 12 patients) according to the operational manner. The intraoperative and postoperative results of two groups were analyzed. Results The operative time [(165.2±6.9) min vs. (130.8±5.5) min], the time to find extrahepatic bile duct [(43.9±3.8) min vs. (23.1±4.1) min] and the amount of bleeding [(207.7±7.7) mL vs. (127.5±15.3) mL] in the control group were longer or more than those in the fluorescence imaging group (P<0.05). The incidence of postoperative infection in the control group [7 cases (35.0%) vs. 0 cases (0.0%)] and the length of hospital stay [(10.8±2.8) d vs. (7.1±1.3) d] were higher or longer than those in the fluorescence imaging group (P<0.05). There were no significant difference between the two groups in the incidence of postoperative bile fistula [6 cases (30.0%) vs. 2 cases (16.7%)] and the incidence of residual stones [3 cases (15.0%) vs. 3 cases (25.0%), P＞0.05]. Conclusion Indocyanine green fluorescence imaging appears to be a feasible, expeditious, useful, and effective imaging method while performing reexploration.
ObjectiveTo explore the postoperative characteristics and management experience of patients with coronavirus disease 2019 (COVID-19) undergoing cardiac and vascular surgery. MethodsFrom December 7, 2022 to January 5, 2023, the patients with COVID-19 who were admitted to Cardiovascular Hospital Affiliated to Kunming Medical University and underwent cardiac and vascular surgery were selected. The clinical history, surgical information, postoperative recovery process and treatment plan were analyzed retrospectively. ResultsThere were 18 patients in this group, including 11 (61.1%) males and 7 (38.9%) females, with an average age of 58.1±10.9 years. There were 7 patients of hypertension, 5 patients of diabetes, 3 patients of respiratory diseases, and 2 patient of chronic renal insufficiency. There were 5 (27.8%) patients receiving emergency operations and 13 (72.2%) elective operations. All the 18 patients underwent cardiac and vascular surgery in the period of COVID-19, and the time between the last positive nucleic acid test and the surgery was 1.50 (1.00, 6.25) days. There were 8 patients of pulmonary imaging changes, including 3 patients with chest patch shadow, 3 patients with thickened and disordered lung markings, and 2 patients with exudative changes before operation. Antiviral therapy was not adopted in all patients before operation. Three patients were complicated with viral pneumonia after operation, including 2 patients with high risk factors before operation, who developed into severe pneumonia after operation, and underwent tracheotomy. One patient with thrombus recovered after anticoagulation treatment. Another patient of mild pneumonia recovered after antiviral treatment. The other 15 patients recovered well without major complications. There was no operation-related death in the whole group. One patient died after surgery, with a mortality rate of 5.6%. Conclusion Patients with COVID-19 are at high risk of cardiac and vascular surgery, and patients with high-risk factors may rapidly progress to severe pneumonia. Patients with preoperative lung imaging changes or other basic visceral diseases should consider delaying the operation. Early antiviral combined with immunomodulation treatment for emergency surgery patients may help improve the prognosis.
Abstract： Objective To summarize the clinical diagnostic and therapeutic experiences of infective endocarditis (IE). Methods From Jan. 2000 to Aug. 2006，60 IE patients underwent heart operation in PLA General Hospital. There were 46 male and 14 female patients, with an average age of 34.3 years old. Blood culture was positive in 25 cases (41.7%), Streptococcus was found in 12 cases, Staphylococcus in 6 cases and other bacteria in 7 cases. Ultrasonic cardiography(UCG) revealed vegetations or valve perforation in 42 cases, including 26 aortic valves, 9 mitral valves and 6 double valves. 28 cases had primary cardiac diseases，including 16 cases of congenital heart anomalies，9 cases of rheumatic heart disease and 3 cases of mitral valve prolapse. High dose of sensitive antibiotics were utilized all through the treatment in all IE patients. There were 55 selective surgeries and 5 emergent ones. Infected tissues were debrided radically，intracardiac malformation was corrected in 16 cases, valve replacement was performed in 41 cases, tricuspid plasty in 1 case. Results There were 3 patients of earlydeath. 51 patients(89.5%) were followedup for 5-71 months with norecurrence. Postoperative cardiac function (NYHA): class I was in 38 cases, class II in 13 cases. Conclusion Early diagnosis, optimal surgical timing, combined internal medicine and surgical treatment provided good therapeutic effect of IE.
ObjectiveTo observe expressions of E3 ubiquitin ligase—mitsugmin53 (MG53) protein, MG53 mRNA, and insulin receptor substrate 1 (IRS-1) mRNA in skeletal muscle of non-obese type 2 diabetic mellitus (T2DM) rats after gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance.MethodsTwenty-four healthy male GK rats were randomly divided into diabetic operation group, diabetic sham operation group, and diabetic control group, 8 rats in each group; besides, 8 male Wistar rats were served as normal control group. The expressions of MG53 protein in skeletal muscle tissue were detected by using Western blot method on week8 after operation. The mRNA levels of IRS-1 and MG53 in skeletal muscles tissue were measured by RT-PCR methods on week 8 after operation.Results① The expressions of MG53 protein and MG53 mRNA in the diabetic sham operation group and diabetic control group were significantly higher than those in the diabetic operation group and the normal control group on week 8 after operation (P<0.05), respectively, which had no significant differences between the diabetic operation group and the normal control group (P>0.05), and between the diabetic sham operation group and the diabetic control group (P>0.05) on week 8 after surgery. ② Compared with the normal control group, the expression of IRS-1 mRNA was significantly decreased in the diabetic operation group, the diabetic sham operation group, and the diabetic control group (P<0.05), while there were no significant differences between the diabetic operation group, diabetic sham operation group, and the diabetic control group on week 8 after operation (P>0.05).ConclusionExpression of E3 ubiquitin ligase—MG53 protein in skeletal muscle tissue in T2DM rats following GBP is decreased, thus reduces the IRS-1 ubiquitin-degradation, increase the expression of IRS-1 protein in insulin signaling pathway of skeletal muscle tissue, and improve insulin resistance of skeletal muscle.
ObjectiveTo discuss the treatment methods and outcome of hilar cholangiocarcinoma. MethodsFrom January 2002 to December 2008, 81 cases of hilar cholangiocarcinoma were retrospectively analyzed. ResultsAmong 81 patients, there were 55 males and 26 females, ages were from 38 to 72 years with an average age 57.5 years. In BismuthCorlette classification, 5 cases were type Ⅰ, 15 cases type Ⅱ, 14 cases type Ⅲa, 14 cases type Ⅲb, 33 cases type Ⅳ, according to the preoperative results of MRCP, but the classification of 15 cases were not consistent to the preoperative results (5 cases type Ⅱ, 8 cases type Ⅲ, 2 cases type Ⅳ) according to the results of intraoperative exploration. The rates of complications of radical operation, palliative operation, internal biliary drainage, and external biliary drainage were 54.5%(12/22), 58.8%(10/17), 23.8%(5/21), and 66.7%(14/21), respectively. The rate of complications of internal biliary drainage was lower than that of the other three methods (Plt;0.01), there were no significant differences among the other three methods. The 1, 2, 3, and 5year survival rates of 22 patients with radical operation, 17 patients with palliative operation, 21 patients with internal biliary drainage, 21 patients with external biliary drainage were 75.0%, 60.0%, 38.3%, 2.6%; 72.7%, 26.5%, 4.2%, 0; 50.5%, 15.8%, 2.2%, 0; 30.6%, 8.5%, 0, 0, respectively. The median survival time was 29.5 months, 13.8 months, 10.5 months, and 8.3 months, respectively. Survival rate of radical operation was higher than that of palliative operation (χ2=14.20, P=0.000 3), palliative operation was higher than that of internal biliary drainage (χ2=4.50, P=0.040 5), and internal biliary drainage was higher than that of external biliary drainage (χ2=4.45, P=0.040 1). ConclusionsThe BismuthCorlette classification is a guide to the required surgery, but the results of intraoperative exploration decides the final classification and operative method. Radical resection is the main related factors influencing the therapy efficacy of hilar cholangiocarcinona. Basinstyle anastomosis and T type supportingtube is the first choice of palliative operation. External drainage, to the full, is avoided.
