ABSTRACT
Objective To study the clinical features and prognostic factors of patients with acute paraquat poisoning.Methods The clinical data of 108 patients with acute paraquat poisoning in Affiliated Hospital of Southwest Medical University from June 2013 to June 2015 were collected and followed up for half a year.The clinical features and prognostic factors were analyzed.Results Of 108 patients,about 90.00％ cases were from the rural areas,the married population accounted for 81.48％.Among them,53 people were living,55 cases were dead,and the death rate was 51.00％.The average amount of poison,average hospitalization time,poison to gastric lavage time interval in the survival group were (22.08 ±5.32) mL,(16.5 ± 3.72) d,(2.00 ±0.49) h,respectively,which in the death group were (88.12 ± 14.96) mL,(5.50 ± 1.20) d,(8.56 ± 1.65) h,respectively.The average amount of poison in the death group was far greater than that of the survival group,about 3.6 times,and the average hospitalization time was significantly reduced,only 1/3 of the survival group.The gastric lavage time interval was also lengthened 1.7 times than that of the survival group,the differences were statistically significant (all P ＜ 0.05).The proportions of fever,increased serum creatinine,liver function damage and pulmonary fibrosis in the death group were significantly higher than those in the survival group,the differences were statistically significant (x2 =12.20,8.35,8.84,50.68,all P ＜ 0.05).Conclusion Mortality rates are still high in patients with acute paraquat poisoning.The amount of poison is still the key factor of death in patients.Early gastric lavage and blood purification,as soon as possible to clear the poison,as far as possible to reduce the absorption of the toxic chemical and aggressive treatment can significantly improve the prognosis of patients.Early fever,liver and kidney function damage and pulmonary fibrosis may predict the poor prognosis of patients.
ABSTRACT
Objective To compare laparoscopic appendectomy to conventional operation for the treatment of appendicitis.Methods In this study 1558 patients diagnosed as appendicitis were divided into group A(laparoscopic appendectomy)and group B(conventional operation)according to the random numbers.In group A,779 patients were treated with laparoscopic appendectomy.In group B,779 patients were treated with conventional open appendectomy.The inhospital data and that of followed-up were compared.Statistical analysis was carried out using SPSS11.5 for Windows.Comparisons between categorical variables and continuous variables were analyzed using the X~2 test and t test.Results The operation was successfully performed in all 1558 patients.The operating time in group A and B were(30±2.2)min versus(30±1.6)min(t=0.00,P>0.05),the blood loss were(15±2.9)ml versus(29±5.2)ml(t=65.62,P<0.05),the bed off activity time were(26±3.1)h versus(51±2.1)h(t=69.95,P<0.05),the bowels'move time were(29±1.6)h versus(52±4.6)h(t=10.92,P<0.05),the hospital stay were(3±0.9)d versus(7±1.2)d(t=74.42,P<0.05),the inhospital cost was (6591±41)yuan versus(4860±32)yuan(t=-12.19,P<0.05),the incision infection rate was 0 and 2.8%(X~2=25.40,P<0.05).Postoperative analgesics were needed in 3.8% and 31.4% (X~2=30.63,P<0.05).All the patients were followed-up from 4.5 years to 9.8 years(average 6.8 years).The development of incision hernia in group A and B was 0 versus 0.64% (X~2=5.01,P<0.05).Conclusions Laparoscopic appendectomy is a therapy of choice for patients with acute appendicitis with advantages of minimal invasion,early recovery,few complications and short hospital stay.

Group A(combined group of 41 cases)with laparoscopic excision,RFA and iodine-125 treatment and group B(control group of 83 cases)with transhepatic artery chemoembolization(TACE)and systematic chemotherapy.Results Nine new hepatic metastatic foci were found by laparoscopic ulstrasound during the operation in group A,and in this group,18 hepatic metastatic lesions located on the surface in 13 patients were removed,then RAF applied to the hepatic metastases,and iodine-125 planted in place,altogether 59 foci near to the porta hepatis or large vessels were treated by laparoscopic RFA and iodine-125 implantation.All patients were followed-up from 26 to 45 months(average 35.4 months).The total relief rate was 90.2% and 30.1 % in group A and B respectively(x~2=39.68,P＜0.05＝.The median survival time was 19 and 11 months in group A and B respectively(t=-9.74,P＜0.05＝.The survival rate at 1-,2-and 3-years was 80.5%,48.8%,24.4% and 54.2%,28.9%,9.6% in group A and B respectively (x~2=8.11,4.73,4.81,P＜0.05＝.Conclusions Laparoscopic excision,Iodine-125 implantation and radiofrequency ablation in the treatment of metastatic liver carcinoma is safe、effective,and this approach prolongs the patient's survival time.
ABSTRACT
Objective To study the efficiency of iaparoscopic inguinal hernia repair without the use of a mesh. Methods We used laparoscopic hernia repair without the use of a mesh in 92 cases of inguinal hernia. Results were compared with that of total extraperitoneal laparoscopic inguinal hernioplasty(TEP) in 91 cases from January 2001 to March 2004. Results The laparoscopic procedures were successfully performed in all the patients. In mesh-free and TEP group respectively the operating time was (21±4) min vs. (70±16) min (t=28. 01, P<0.05), hospital stay was (3.5±1.0) d vs. (4.8±1.2) d (t=7.96, P<0.05), average time off-bed was (1.0±0.5) d vs. (1.8±0.7) d (t=8.90, P<0.05), duration of pain was (1.0±0.5) d vs. (2.5±0.7) d (t=16.69, P<0.05), the expense was (4500±500) RMB yuan vs. (8000±820) RM B yuan(t=34.89, P<0.05), subcutaneous hematoma rate was 0% vs. 8.7% (χ~2=6.48, P<0.05). The 48 hour C-reaction protein level after the operation was (3.9±0.3) mg/dl and (8.8±0.5) mg/dl (t=80.48, P<0.05). All the difference was statistically significant between the two groups. All patients were followed up for 56.9±6.2 months. The recurrence rate was 0 and 2.1% (χ~2=0.51,P>0.05) respectively.

ABSTRACT
Objective To evaluate the feasibility and efficacy of laparoscopic thyroidectomy in the treatment of thyroid carcinoma. Methods 12 patients with thyriod carcinoma treated with laparoscopic thyroidectomy from January 2003 to January 2006 in our hospital were analyzed retrospectively. Results All operations were successful and there were no surgical deaths. The postoperative complications included 2 cases of hoarseness, 1 extremity numbness and 1 temporary hypoparathyroidism. The number of dissected lymph nodes was from 0 to 13 with a mean of 7.6 nodes in each patient. Of the 12 patients, there was one patient with bilateral lymph nodes metastasis, 5 patients unilateral positive lymph nodes and 6 patients no lymph nodes involvement. The pathologic result of all 12 cases was papillary thyroid carcinoma. After 30 to 62 months' follow-up (average 50.4 months), all patient were still survive and no local recurrence or distance metastasis happened. Conclusion Laparoscopic thyroidectomy in the treatment of early papillary thyroid carcinoma is safe and feasible.
ABSTRACT
Objective To investigate the therapeutic effectiveness of residue liver embedding of iodine-125 on recurrence after hepatectomy in hepatocellular carcinoma patients. Methods In this study, 85 cases with resectable hepatocellular carcinoma were collected and divided into two groups randomly: intrahepatic embedding of iodine-125 group and control group. The serum values of T lymphocyte phenotypes (CD3 + CD4 + ,CD8 +), NK cells,TB IL, ALT, AST, AFP and MMP-9 were measured in all patients 1 day before and 7, 30 days after the operation respectively; B ultrasonic and CT were used to detect for intrahepatic dissemination and recurrence of HCC after hepateetomy. All patients were followed-up from 16 to 55 months (average 35.4 months). Results Surgery were successful in all cases. There were no difference in T lymphocyte phenotypes, NK cells, TBIL, ALT and AST between the two groups (P＞0.05). The serum values of AFP and MMP-9 were much lower in the intrahepatic embedding of iodine-125 group than the control group(P<0.05). In iodine-125 embedding group, the 0.5-, 1-year recurrent rates were 2.3%、6.9%, respectively, compared with 14.2% and 26.1%, respectively, in control group (all P<0.05). Conclusions Intrahepatic embedding of iodine-125 in HCC patients after hepatectomy decreases values of AFP, MMP-9 and local cancer recurrence rate in HCC patients after hepatectomy.
ABSTRACT
Objective To explore the feasibility and surgical techniques of laparoscopic cholecystectomy(LC) in the treatment of incarcerated cystic duct stones associated with gallbladder empyema. Methods Laparoscopic cholecystectomy was performed in 76 cases of acute cholecystitis with incarcerated cystic duct stones and gallbladder empyema.During operation the cystic duct was found wide in 37 cases and was transected with overlapped clipping(11 cases),large-sized titanium clipping(9 cases),preformed knot ligation(3 cases),or Hem-o-lok ligation(14 cases),respectively.Cystic duct stones were removed during operation in 9 cases.Gallbladder bed hemorrhage occurred and was successfully stopped in 6 cases.Partial cholecystectomy was conducted in 6 cases. Results Laparoscopic cholecystectomy was successfully accomplished in all the 76 cases.The operation time was 50~125 min(mean,65.0?32.8 min).A drainage tube was placed in all the cases and was removed at 18~36 hours postoperatively,with a drainage volume of 40~90 ml/d (mean,55.0?10.4 ml/d).Biliary leakage happened in 2 cases and was cured with indwelling abdominal drainage.No patients were complicated with postoperative hemorrhage,visceral injuries,or bile duct injuries. Conclusions Laparoscopic cholecystectomy in the management of incarcerated cystic duct stones associated with gallbladder empyema is feasible.
ABSTRACT
Objective To study the efficacy of laparoscopic tumor resection combined with iodine-125 and radiofrequency ablation in the treatment of rectal carcinoma with synchronous hepatic metastasis. Methods There were 30 patients diagnosed as rectal carcinoma with synchronous hepatic metastasis detected by CT scan. Hepatic metastases were confirmed by needle biopsy under laparoscopy. Laparoscopic radical resection of rectal carcinoma and metastatic hepatic tumors was performed. Those metastatic tumors that could not be resected were managed by RAF. Iodine-125 was planted in the tumors' site. Results Seven new hepatic metastases were found by the laparoscopic ulstrasound during the operation. 8 hepatic metastatic lesions were removed, 25 tumors located in the right liver were managed by RAF. All patients were followed-up from 12 to 25 months(average 22. 3 months), Local recurrence was found in 6 patients, the 1-year survival rate was 73% (22/30). Conclusions Laparoscopic excision, Iodine-125 and radiofrequency ablation in the treatment of rectal carcinoma with synchronous hepatic metastasis is safe、effective、minimally invasive.
