ABSTRACT
Objective To compare the surgical effect of gasless endoscopic thyroidectomy and CO2- insufflation endoscopic thyroidectomy, and evaluate the safety and applicability of gasless endoscopic thyroidectomy. Methods A prospective randomized controlled study was carried out.Sixty patients who were scheduled for bilateral thyroid surgery under endoscope were divided into 2 groups by sortition method: gasless group (30 patients, treated with gasless endoscopic thyroidectomy) and CO2-insufflation group (30 patients, treated with CO2-insufflation endoscopic thyroidectomy). The data of arterial partial pressure of carbon dioxide (PaCO2) and pH value before operation and 60 min after operation were detected. The operation time, intraoperative bleeding, time of putting the drain, hospitalization time after operation and postoperative complications were recorded. Results All the 60 patients completed endoscopic surgery,and no case was converted to the conventional procedure.There were no statistical differences in PaCO2and pH value before operation between 2 groups(P>0.05).The PaCO260 min after beginning of operation in gasless group was significantly lower than that in CO2-insufflation group:(36.43 ± 1.98)mmHg(1 mmHg=0.133 kPa)vs.(37.93 ± 3.27)mmHg,the pH value 60 min after beginning of operation was significantly higher than that in CO2-insufflation group:7.42 ± 0.02 vs. 7.37 ± 0.01, and there were statistical differences (P<0.05 or <0.01). There were no statistical difference in operation time, intraoperative bleeding, time of putting the drain, hospitalization time after operation and incidence of hoarseness between 2 groups (P>0.05). There were no complications related with trachea, parathyroid gland and superior laryngeal nerve in 2 groups. The incidence of CO2retention related complications in gasless group was significantly lower than that in CO2-insufflation group: 6.7% (2/30) vs. 43.3% (13/30), and there was statistical difference (P<0.01). Conclusions The modified spring suspension gasless endoscopic thyroidectomy not only acquires the equivalent surgical effect and indication,compared with the CO2-insufflation endoscopic surgery,but also is safer and has lower incidence rate of CO2retention related complications.
ABSTRACT
Objective To study the application value of endoscopic thyroidectomy via total membrane dissection. Methods One hundred and sixteen patients with benign thyroid nodules were given axillo-breast approach endoscopic thyroidectomy via total membrane dissection from January 2014 to December 2016. Results Endoscopic thyroidectomy was completed in all the patients without conversion to open surgery.The operation time was 45-125 min[mean,(65.6 ±36.7)min],the blood loss was 10-220 ml[mean,(43.2 ±22.7)ml],the postoperative drainage volume was 25-305 ml[mean,(95.3 ±53.8)ml], the postoperative drainage time was 2-4 d[mean,(2.3 ±0.7)d)],and the length of hospital stay was 3-6 d[mean,(4.1 ±1.1)d].Short-term twitch occurred in 1 case and seroma occurred in 2 cases.No other complications such as hoarseness,bucking or asphyxia occurred in this series. Conclusion Endoscopic thyroidectomy via total membrane dissection can effectively avoid the injury of recurrent laryngeal nerve and parathyroid gland.
ABSTRACT
A retrospective study was conducted based on the clinical data of 42 patients of portal hypertension and splenomegaly who underwent laparoscopic splenectomy.The patients were divided into two groups including pedicle priority group and conventional group by different operative method.The operation time and intraoperative blood loss in the pedicle priority group were significantly lower than those in the conventional group (both P < 0.05),and there was no statistically significant difference on the conversion rate of laparotomy,active time postoperation,exhaust time,postoperative hospitalization stay and the incidence of complications (all P > 0.05).Priority processing for splenic pedicle has obvious advantages in laparoscopic splenectomy for portal hypertension and splenomegaly,and it could reduce the difficulty of operation,shorten the operation time and reduce bleeding.
ABSTRACT
ObjectiveTo discuss the more aesthetic and minimally invasive surgical approach of endoscopic thyroidectomy.Methods50 cases of endoscopic thyroidectomy via breast areola-axillary approach were retrospectively analyzed.Among these cases,12 received unilateral partial lobectomy,30 received unilateral total lobectomy and 8 received bilateral partial lobectomy.Results Endoscopic thyroidectomy was completed in all the patients.The intraoperative blood loss was ( 12.77 ± 20.12 ) ml.The operation time was (67.00 ± 21.28 )min.The postoperative hospital stay was (3.77 ± 0.50)days.Hoarseness occurred in 2 cases.All the 50 cases were followed up from 1 to 6 months and no other complication occurred.ConclusionEndoscopic thyroidectomy via breast areola-axillary approach is more aesthetic and minimally invasive; however,the operator needs an adaptive process for a better surgical view angle.
ABSTRACT
Objective To investigate diagnosis and surgical treatment of primary retroperitoneal malignarnt tumor.Methods Retrospectively analyzed the clinical data with primary retroperitoneal tumor.Results Twenty-eight eases with benign tumor and 47 cases with malignant tumor underwent total resection,only 17cases with malignant tumor underwent local resection.Conclusion The diagnosis B-ultrasonography,CT and MR of primary retroperitoneal tumor is very important for preparative of preoperation and to estimate of involved organ.Involved organ resection and repeated operation for recurred tumor improve cure rate.
ABSTRACT
Objective Observe the effect of simple closure for the treatment of perforated duodenal ulcers and the efficacy of laparoscopic repair in the condition of modern medical treatment.Methods 65 cases with duodenal ulcer perforation were operated on simple closure with open or laparoscopy.All patients were received triple therapy of lansoprasole 30 mg qd+am oxycillin 1g bid+furazolidone 0.1 g tid for a week and were followed up for 3~31 months.Results The ulcer cure rate was 96.9% after the triple therapy had been finished for one month.Postoperatevely,the ulcer recurrence rates within one and two years were 4.2% and 5.9%.No one was reoperated because of ulcer recurrence.The length of hospital stay had a very significant difference between open operation group and laparoscopy group.Conclusion The operation of simple closure,especially laparoscopic repair is simple and safe,and should has a priority to treat perforated duodenal ulcers.
