[Summary] In this case report , a 44-year-old female patient complained of three years of tightness and chest pain , and was hospitalized in January 2016.The thymus and tumor were completely resected under video-assisted thoracoscopic surgery (VATS). Postoperative pathological examination presented a thymic mucoepidermoid carcinoma .The patient received 30 times of chemotherapy after operation and were followed up for 2 months.Postoperative recovery was smooth without symptoms .The CT scanning showed negative result .We consider that VATS was feasible and safe for the treatment of thymic carcinoma .
7.Controversy on the Oddi Sphincter Function in the Treatment of Hepatolithiasis:Preservation Versus Deprivation
Chinese Journal of Minimally Invasive Surgery 2016;16(10):931-935
[Summary] The controversy remains on whether the Oddi sphincter function should be preserved or deprived in the treatment of hepatolithiasis .The surgical approaches achieving both hepatobiliary lesions clearance and Oddi sphincter preservation have been widely accepted .The biliary-enterostomy is suspected to increase the risk of reflux cholangitis and cholangiocarcinoma due to iatrogenic Oddi sphincter deprivation.Endoscopic sphincterotomy (EST) as a minimally invasive method still needs further research to determine its role in hepatolithiasis management .

Objective To investigate the clinical efficacy of endovascular treatment for iliac vein compression syndrome (IVCS) in 112 cases. Methods From September 2011 to June 2015, 112 cases of IVCS (Cockett syndrome) were treated in our hospital with endovascular methods .The case numbers of different CEAP ( clinical etiological anatomical pathophysical ) classifications were C2 (45 cases), C3 (23 cases), C4 (19 cases), C5 (11 cases) and C6 (14 cases).All the cases were diagnosed by venography .The operations started from puncturing the ipsilateral veins .The stenotic degree and compressed intensity of iliac vein were evaluated by the minimum diameter with low pressure balloon .And then a stent was placed into after percutaneous transluminal angioplasty ( PTA) when residual stenosis was more than 50%.The occlusive segment was dilated by 8 mm diameter balloon firstly , and catheter directed thrombolysis treatment was applied if thrombus was detected .The PTA and stenting were performed when the thrombus was completely removed .The improvement of clinical symptoms was observed after operation and the patients were followed up by ultrasound and venograghy . Results Nine cases were given PTA only , and the other 103 cases underwent stent placement . Postoperative venography showed collateral vessels were disappeared in 22 cases, obviously decreased in 56 cases and mildly decreased in 34 cases.The average difference of swelling leg ’s circle was diminished from (2.56 ±0.88) cm pre-operation to (0.93 ±0.71) cm post-operation, while the average area of skin ulcer was diminished from (6.34 ±3.78) cm2 pre-operation to (2.13 ±1.88) cm2 post-operation, all of which were statistically significant (t =20.24 and 7.19,P=0.000).A total of 86 cases were successfully followed up during a period from 2 months to 45 months (average, 19.2 months).The patency rate of treated iliac vein 12 months after operation was 76.2%in the PTA group, and in the PTA with stenting group was 96.7%, 88.6%, and 86.1%, respectively, at 12, 24, and 36 months after operation, in which a statistical significance was detected (log-rank χ2 =30.32, P=0.000).The patency rate in diameter ≥16 mm group was 95.2%and 95.2%, respectively, at 12 and 24 months after operation, while in diameter <16 mm group was 97.0%and 93.3%, respectively, in which no statistical significance was detected (log-rankχ2 =0.39, P=0.532).Thrombotic complication was found in 2 cases during the follow-up period , including 1 case of iliac vein thrombosis at 1 month and 1 case of thrombus in contralateral leg 8 months later .According to the results of venography in 78 cases at 12 months after operation , restenosis was found in 5 out of 6 cases in the PTA group, and the patency rate in the stent placement group was 95.8%(69/72).No stent migration was found . Conclusion Comfortable clinical results were obtained after endovascular therapy for iliac vein compression syndrome , and the application of stenting could increase the middle and long term patency rate of treated vessels .

Objective To investigate curative effects and prognostic factors of video-assisted thoracoscopic extended thymectomy ( VATET ) for nonthymomatous myasthenia gravis ( NTMG ) . Methods Clinical records of 43 patients with an established diagnosis of NTMG who underwent VATET from December 2009 to September 2014 were reviewed. Three-port thoracoscopic right thymectomy with resection of fat tissue in anterior mediastinum was conducted.The curative effects and prognostic factors were evaluated and analyzed with the Monden standard. Results The VATET was successfully completed in all the 43 patients.The operation time was 75-240 min (mean, 115.4 min).The intraoperative blood loss was 10-200 ml (mean, 42.2 ml). No peri-operative death occurred.Follow-ups for 4 -60 months ( mean, 36.2 months) showed 12 cases of remission, 18 cases of improvement, 10 cases of unchanged disease, and 3 cases of deterioration.The effective rate was 69.8% (30/43).Multivariate logistic regression analysis showed that pathological type of thymic hyperplasia was the independent risk factor for NTMG postoperative outcomes (β=0.921,95%CI:1.866-2.811, P=0.000). Conclusion Video-assisted thoracoscopic extended thymectomy is effective in most myasthenia gravis patients.

Objective To study the initial experience and outcomes of laparoscopic enucleation with preoperative selective arterial embolization ( PSAE) for the treatment of renal angiomyolipomas. Methods A total of 43 patients with sporadic renal angiomyolipomas from July 2013 to November 2014 underwent laparoscopic nephron-sparing surgery ( NSS) .The patients were divided into either PSAE group ( n =19 ) or non-PSAE group ( n =24 ) .The data of patient demographics, success rate of surgery, perioperative complications rate, operating time ( OT ) , warm ischemia time ( WIT ) , estimated blood loss ( EBL ) , length of hospitalization, kidney estimated glomerular filtration rate (eGFR) and serum creatinine (Scr) level over 3 months, and ipsilateral recurrence were collected and compared between the two groups. Results Enucleation was successful in 100%patients (19/19) of the PSAE group and in 62.5%patients (15/24) of the non-PSAE group,with no significant difference ( Fisher' s test, P=0.105) The EBL was (46.4 ±20.6) ml in the PSAE group, which was significantly less than the non-PSAE group [(89.5 ±30.4) ml, t=-5.287, P=0.000].The OT and WIT were significantly shorter in the PSAE group than those in the non-PSAE group [(90.3 ± 21.1) min vs.(131.7 ±18.6) min, t=-6.831,P=0.000;(9.5 ±5.7) min vs.(24.2 ±4.8) min, t=-9.181, P=0.000]. The length of hospitalization was significantly longer in the PSAE group than that in the non-PSAE group [(7.7 ±1.1) d vs.(6.3 ± 1.3) d, t=3.748, P=0.000].No severe complications occurred in the PSAE group, whereas the non-PSAE group had 1 case of urinary leakage and 1 case of hematoma.The Scr level over 3 months after surgery was more ideal in the PSAE group [(70.1 ±13.7)μmol/L vs.(84.2 ±9.1) μmol/L, t=-4.045, P=0.000].No statistically significant difference was found in the eGFR between the PSAE group and the non-PSAE group [(72.6 ±12.8) ml· min-1· 1.73 m-2 vs.(68.0 ±10.7) ml· min-1· 1.73 m-2, t=1.284, P=0.206].No evidence of recurrence was found during follow-up period in both groups. Conclusions Laparoscopic enucleation with PSAE is a safe and effective minimally invasive procedure for the treatment of renal angiomyolipomas.As compared to traditional laparoscopic partial nephrectomy, it has advantages of less WIT, less EBL, and better protection of renal functions.It can be recommended in well-selected patients.
