ABSTRACT
Objective To analyze the safety and clinical effects of laparoscopic partial splenectomy for splenic solid benign lesions.Methods Retrospective analysis was made on patients with splenic solid benign tumor admitted from Jan 2015 to Feb 2017.Results 6 patients (4 males,2 females) underwent successful partial splenectomy for splenic tumors.Mean patient age was 44.7 years (range,28-58 years).5 patients were diagnosed by wellness examinations,1 patient had abdominal discomfort.The diameter of tumors ranged from 5.0 to 8.3 cm.Tumors were located in the superior lobes in 2 cases and the others were located in the inferior lobes.The operation times were 120-240 min and intraoperative blood loss was 50-1 400 ml (mean,375 ml).Laparoscopic procedure was successful in all patients without major complications.Postoperative pathology showed hemangioma in 5 cases and hemangioendothelioma in one patient.After 3 to 28 months follow-up no patients experienced recurrence.Conclusions Laparoscopic partial splenectomy is safe and effective in patients with focal benign splenic lesion that was located at the edge of the spleen or in the upper or lower pole of the spleen.
ABSTRACT
Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

Objective To compare the effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) for the treatment of type 2 diabetes mellitus (T2DM) patients in various obesity degree.Methods A total of 36 T2DM patients undergoing LRYGB were enrolled in this study in our hospital from June 2012 to June 2014.The patients were divided into BMI ≥ 32.5 kg/m2 group (n =13) and 27.5 kg/m2 ≤ BMI ＜ 32.5 kg/m2 group (n =23) based on BMI.Results In group 1,following the degression of BMI from (37.7±3.6) kg/m2 to (29.1 ±3.5) kg/m2 at 12 months after surgery,fasting blood glucose of group 1 decreased from (7.8 ± 1.6)mmol/L to (5.2 ±1.0)mmol/L (t =5.796,P =0.000),and HbA1c decreased from 7.3％ ±0.7％ to 6.1％ ± 1.0％ (t =5.589,P =0.000);and following the degression of BMI from(30.0 ± 1.6) kg/m2 to (25.8 ± 3.2) kg/m2,fasting blood glucose of group 2 decreased from (8.9 ± 1.7) mmol/L to (6.1 ± 1.5) mmol/L (t =6.577,P =0.000),and HbA 1 c decreased from 7.8 ％ ± 1.8％ to 6.4％ ± 1.0％ (t =4.257,P =0.000).Though Homa-IR of two groups was significantly improved after surgery (t =6.415,4.135;P =0.000,0.000),there was no difference to Homa-β (t =1.007,-0.155;P =0.334,0.878).Complete remission ratio of BMI ≥ 32.5 kg/m2 group was not significantly different with 27.5 kg/m2 ≤ BMI ＜ 32.5 kg/m2 group.Conclusion LRYGB is effective for the treatment of type 2 diabetes patients despite preoperative various obesity degree.
ABSTRACT
Objective To compare the clinical effect between retropubic extraperitoneal laparoscopic prostatectomy with prostatic urethra preservation and transurethral resection of the prostate (TURP) for giant benign prostatic hyperplasia (BPH).MethodsThe clinical data and follow-up of 128 cases of giant BPH were analyzed retrospectively.Seventy-two cases underwent TURP (TURP group) and 56 cases underwent retropubic extraperitoneal laparoscopic prostatectomy with prostatic urethra preservation ( laparoscopic group ).The operation time,blood loss,gland mass excision,bladder washing time,catheterization time,hospital stay,hospital cost,international prostate symptoms score (IPSS) and quality of life questionnaires (QOL),maximum flow rate (MFR),residual urine volume (RUV) were compared between two groups.ResultsThe bladder washing time,catheterization time,hospital stay in laparoscopic group were less than those in TURP group[0 d vs.(2.8 ± 1.2) d,(2.3 ± 0.6) d vs.(5.2 ± 1.5) d,(4.2 ± 0.5) d vs.(7.5 ±0.5) d],gland mass excision in laparoscopic group was more than that in TURP group [(100.2 ±25.4) g vs.(85.6 ± 15.5) g],there were significant differences between two groups(P＜ 0.05).There was no significant difference in the operation time,blood loss,hospital cost between two groups (P ＞ 0.05).There were significant differences in IPSS,QOL,RUV and MRF before and after 3,6 months treatment for two groups [ laparoscopic group:(9.1 ± 3.4),(7.5 ± 2.5 ) scores vs.(27.5 ± 5.8) scores,( 1.8 ± 1.1 ),( 1.6 ± 0.8)scores vs. (5.5 t0.5) scores,(26.5 ± 11.5),(22.4 ± 12.6) ml vs. (145.0 ±48.0) ml,(17.6 ±8.4),(20.2 ± 5.4) ml/s vs.(8.3 ± 3.5) ml/s;TURP group:(9.2 ± 3.8),(7.8 ± 2.2) scores vs.(28.5 ± 5.4) scores,( 1.9 ± 1.2),( 1.7 ± 0.6) scores vs.(5.0 ± 0.5 ) scores,(28.5 ± 12.9),(23.0 ± 11.7) ml vs. ( 155.0 ± 47.0) ml,( 17.8 ± 9.2),( 19.8 ± 4.5 ) ml/s vs.(7.2 ± 3.2 ) ml/s ] (P ＜ 0.01 ),but there was no significant difference between two groups (P ＞ 0.05).ConclusionsThe clinical effect of two microtrauma surgery are good.Laparoscopic technique is a feasible treatment option for patients suffered from giant BPH for which has the benefit of a quicker recovery,shorter hospital stay,less complications,no bladder washing.
ABSTRACT
Objective To explore the feasibility and application skills of transabdominal preperitoneal prosthesis (TAPP) with cross-encircling arms of mesh.Methods From Septemer 2009 to February 2012,46 cases were given TAPP with cross-encircling arms of mesh.The clinical data and surgery videos were retrospectively analyzed.Results All of the 46 cases with 53 inguinal hernias were successful in TAPP.The mean operative time of unilateral hernia was (57.74 ± 11.89) min,the mean operative time of 7 cases with biliateral hernia was (83.86 ±20.42) min and the longest time was 125 min.There were 6 cases with the contralateral hidden hernia,2 cases with hematoma,1 case with paresthesias of skin,no realpse.Conclusion The mesh with cross-encircling arms can be exactly fixed by spermatic cord,ductus deferens or round ligament of uterus,without stitching and stappling.
ABSTRACT
Objective To evaluate laparoscopic appendectomy(LA) and open appendectomy(OA)in obese patients.Methods From January 2008 to November 2010,153 obese patients with appendicitis were operated on,92 cases were treated with initial LA and 61 cases with upfront OA.The operative time,intraoperative bleeding volume,intestinal recovery period,the rate of using acesodyne,major postoperative complications,the duration and hospital cost were studied.Results In LA group,4 cases were converted to open surgery.All the variables in LA group were better than those in OA group except the hospital cost and the differences were statistically significant (the operative time:t =14.0,P ＜ 0.001 ;intraoperative bleeding volume:t =19.7,P ＜ 0.00 1 ;intestinal recovery period:t =12.3,P ＜ 0.001 ;the rate of using acesodyne:t =21.01,P ＜ 0.001 ;main postoperative complications:x2 =40.138,P ＜ 0.001 ;the hospital stay:t=17.3,P＜0.001) except the in-hospital cost(t=1.434,P＞0.05).Conclusions Compared with OA,LA is a better choice for obese patients with appendicitis because of its advantages of minimal injury,early recovery,less complications and short hospital stay.
ABSTRACT
ObjectiveTo compare the clinical effects of laparoscopically assisted vaginal hysterectomy (LAVH) and transabdominal hysterectomy (TAH).MethodsOne hundred and twenty-six cases operated with hysterectomy were classified into LAVH group and TAH group by random digits table with 63 cases each.The operation time,intraoperative bleeding amount,exhaust time,hospitalization time and postoperative complications were observed and compared.ResultsThe operation time,intraoperative bleeding amount,exhaust time and hospitalization time was ( 115.6 ± 13.8 ) min,(92.5 ± 11.3 ) ml,(21.8 ±4.8) d and (6.1 ± 1.7) d in LAVH group,( 82.5 ± 8.7) min,( 112.3 ± 17.8) ml,(28.9 ± 6.2) d and (9.6 ±2.2) d in TAH group,there were significant differences between two groups (P＜0.05).The incidence of incision pain,delayed wound healing,vaginal stump infection,thrombophlebitis,and gastrointestinal disorders was 9.5％(6/63),0,1.6％(1/63),0 and 7.9％(5/63) in LAVH group,which was significantly lower than that in TAH group [52.4％(33/63),7.9％(5/63),11.1％(7/63),7.9％(5/63) and 22.2％ ( 14/63 ) ] (P ＜ 0.05).ConclusionCompared with TAH,LAVH can shorten exhaust time,hospitalization time,reduce intraoperative bleeding amount,decrease complication rate,which can be further applied in clinic.
ABSTRACT
Objective To improve the early diagnosis and differential diagnosis of adrenal incidentalomas to guide clinical management of this disease. Methods One hundred and twenty-eight cases were diagnosed as adrenal incidentalomas due to health examination or treatment of other than adrenal disease,including 60 males and 68 females,whose ages were between 20 and 75 years,with a mean age of 50 years.Tumor diamer:＜3 cm 63 cases,3-6 cm 6 cases,＞6 cm 10 cases.128 patients all had biochemical and electrolyte examination,adrenal cortex and medulla biochemical testing,abdominal ultrasound and CT examination,6 cases with MRI examination.Surgery and post operative pathological examination were performed in all patients. Results Post operative pathology finally diagnosed adrenocortical adenoma in 85 cases,pheochromocytoma in 13 cases,adrenal cyst in 8 cases,paraganglioma and myeiolipoma in 7 eases respectively,adrenal nodular hyperplasia in 4 cases,adrenocortical carcinoma in 2 cases,adrenoconical oncocytoma,cellular Schwannoma and adrenal liposarcoma in 1 case,respectively.One case of pheochromocytoma patients died of intraoperative hypotension,which is not included in the total number. Conclusions The preperative diagnosis of adrenal incidentalomas is difficult.For adrenal incidentalomas with diameter more than 6 cm and those with endocrine function,early surgicM treatment is recommended.
ABSTRACT
Objective To investigate management strategy of minimally invasive surgery for common bile duct stones. Methods Three hundred and four cases of common bile duct stones were divided into 3 groups receiving respectively endoscopic papillary balloon delation plus laparoscopic cholecystectomy ( EPBD group, 35 cases ), endoscopic sphincterotomy plus LC ( EST group, 138 cases), and Laparoscopic common bile duct exploration plus LC (LCBDE group, 131 cases). Results There was no significant difference in treatment success rate, short-term complications and bile duct retained stones among these three group ( x2 = 1. 930, 0. 038, and 0. 427 respectively, P > 0. 05 ). There was significant difference among these three groups in operation time ( F = 17.941, P = 0. 000 ), and the operation time in LCBDE group was shorter than that in other two groups( EPBD-EST: P = 0. 122, EST-LCBDE:P = 0. 000, EPBD-LCBDE:P = 0. 020 ). There was significant difference among these three groups in postoperative hospital stay (F =24. 016,P =0. 000) ,and the postoperative hospital stay in EPBD group was shorter than that in other two groups ( EPBD-EST: P = 0. 000, EST-LCBDE : P = 0. 198, EPBD-LCBDE : P = 0. 000 ). In EPBD group,bile duct recurrent stones was found in 2 cases(6. 7% ) and cholangitis in 1 case(33% ) and no duodenal papilla stenosis was encountered; In LCBDE group, bile duct recurrent stones were found in 7 cases (6. 0% ), cholangitis in 3 cases ( 2. 6% ), and there was no duodenal papilla stenosis; In EST group, bile duct recurrent stones were complicated in 18 cases ( 15.8% ), duodenal papilla stenosis in 9 cases (7.9%), and cholangitis in 14 cases( 12. 3% ). There were significant differences among these three groups for these three complications( x2 = 6. 482, 9. 160, and 12. 020 respectively,P < 0. 05 ), and the rate of complications in EST group was higher than that in other two groups. Conclusion For common bile duct stones, EPBD is the first choice followed by LCBDE while EST is only indicated for very few cases.
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.
ABSTRACT
Objective To study the feasibility of laparoscopic resection of colorectal cancer.Methods A(retrospectively) analysis of the clinical data of 110 patients with colorectal cancer treated by laparoscopic(resection) during last three years was made.Of them,24 cases were converted to open operation.In 86 (cases),laparoscopic resection of colorectal cancer was completed.Among them,5 cases underwent right(hemicolectomy),2 cases left hemicolectomy,10 cases sigmoidectomy,22 cases Dixon′s operation,46 cases of Miles operation,and 1 case total colorectomy.Results No patient died within 30 days postoperatively in this series.The average operation time was 225(120-360) min with average 135(20-400) mL blood loss.The average number of lymph nodes excised was 8.7(1-30).The average number of positive lymph nodes was 2.2(0-24).Six cases had intraoperative complications,including 1 case of ureteral injury and 5 cases of intra-abdominal bleeding.These patients were immediately converted to open surgery.There were 6 cases with postoperative complications,among them,2 cases of urinary leakage,2 cases of massive bleeding and 2 cases of intestinal obstruction.All of them recovered after reoperation.The time of bowel funtion(recovering) was 12-72h after operation.The hospital stay after operation was 8.6(7-15)days.The median follow-up was 14.3 months(range 1-33) for 100(90.9%) patients.There was no port-site tumor(metastasis) and no tumor recurrence at the small abdominal incision.Six to fifteen months after opteration,3 cases had diffase peritoneal metastases.1 case of Miles resection had perineal metastasis 3 months after(surgery).Conclusions Laparoscopic resection of colorectal cancer is technically feasible,and have(advantages),such as less surgical trauma,less bleeding,less gastrointestinal interference and quicker(recovery).Laparoscopic radical operation for colorectal cancer can meet the requirements of safety and radical operation.
