ABSTRACT
【Objective】 To evaluate the efficacy and safety of 3-dimensional laparoscopic pyeloplasty and ultrasound-guided flexible ureteroscopy lithotripsy (3DLP-UGFURL) in the treatment of ureteropelvic junction obstruction (UPJO) and renal calculi. 【Methods】 The clinical data of 29 patients of UPJO complicated with renal calculi treated with 3DLP-UGFURL during Dec.2017 and Jul.2022 were retrospectively analyzed. There were 23 males and 6 females with average age of (35.3±13.6) years. The lesions were on the left side in 20 cases, on the right side in 9 cases, and all were unilateral. One case was complicated with horseshoe kidney. The body mass index (BMI) was 23.6±3.9. Multiple calculi of renal pelvis or calyces occurred in 16 cases, and the rest were single calculi. The maximum diameter of calculi was (1.2±0.6)cm. There were 2 cases of mild hydronephrosis, 19 cases of moderate hydronephrosis and 8 cases of severe hydronephrosis. 【Results】 All operations were successful. The operation time of 3DLP was (84.2±15.4)min. Operation time of UGFURL was (42.8±15.7)min. Estimated blood loss was (36.9±13.6)mL. Indwelling time of drainage tube was (3.6±1.6)d. Indwelling time of urinary catheter and postoperative hospital stay was (6.8±1.2)d. One month after operation, the stone removal rate was 97.4%. The retention time of ureteral stent was 2.7 months. During the follow-up of (24.5±10.0)months, there were 45 Clavien Dindo grade 1 complications. 【Conclusion】 3DLP-UGFURL is safe and effective in the treatment of UPJO complicated with renal calculi, but it still needs long-term follow-up data.
ABSTRACT
Objective:To explore the effect of enhanced recovery after surgery (ERAS) protocols in patients undergoing laparoscopic radical cystectomy (LRC) and intracorporeal urinary diversion (ICUD).Methods:A total of 83 patients who received LRC+ ICUD in Beijing Chaoyang Hospital from March 2014 to September 2020, were divided into 2 groups based on different perioperative management, including 29 ERAS cases and 54 conventional recovery after surgery (CRAS) cases. The ERAS group included 26 males and 3 females , with an average age of (62.07 ± 9.26) years. There were 26 patients with ASA class Ⅰ-Ⅱ, 3 patients with ASA class Ⅲ, 4 patients received neoadjuvant chemotherapy, and 7 patients had a history of abdominal surgery in ERAS group. The CRAS group included 44 males and 10 females , with an average age of (61.59 ± 10.16) years. There were 50 patients with ASA class Ⅰ-Ⅱ, 4 patients with ASA class Ⅲ, 9 patients received neoadjuvant chemotherapy, and 10 patients had a history of abdominal surgery in CRAS group. There were no statistically significant differences in the baseline characteristics between the two groups. The patients in both groups underwent LRC+ ICUD procedures. The perioperative results and complications between the two groups were compared.Results:In the ERAS group, there were 20 patients who underwent Bricker ileal conduit surgery and 9 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 3, 3, 7, 7, 5 and 4 cases in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 23, 2, 3 and 1 patient with pathological stage N 0, N 1, N 2 and N 3, respectively. Pathological diagnosis included 3 cases of low-grade urothelial carcinoma, 24 cases of high-grade urothelial carcinoma, and 2 cases of other histological subtypes. In the CRAS group, there were 31 patients who underwent Bricker ileal conduit surgery and 23 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 5, 3, 12, 9, 15 and 10 patients in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 35, 6, 7 and 6 patients with pathological stage N 0, N 1, N 2, and N 3, respectively. Pathological diagnoses included 6 cases of low-grade urothelial carcinoma, 45 cases of high-grade urothelial carcinoma, and 3 cases of other histological subtypes. There were no statistically significant differences ( P>0.05) in surgical methods, pathological staging, or pathological types between the ERAS and CRAS groups. ERAS group presented less albumin loss [(25.73±8.63)% vs. (32.63±9.05)%, P=0.001], shorter hospital stay [9(7, 13)d vs. 12(9, 16)d, P=0.006], less 30-day overall complications [55.2% (16/29) vs. 83.3% (45/54), P=0.009]. In multivariable analysis, maximum albumin loss≥20% was independently associated with 30-day minor complications ( P=0.049), and maximum albumin loss ≥25% was independently associated with hospital of stay≥10 days ( P=0.038), respectively. Conclusions:For patients who received LRC+ ICUD, ERAS was associated with reduced perioperative albumin loss, shorter length of stay, less 30-day complications, accelerated recovery time, improved clinical outcome and less albumin injection.
ABSTRACT
Objective:To investigate the clinical features of diagnosis and treatment of renal parenchymal invasive urothelial carcinoma.Methods:The clinical data of 23 patients with renal parenchymal invasive urothelial carcinoma admitted to Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2014 to December 2020 were retrospectively analyzed. There were 12 males and 11 females. The mean age was (67.3±10.1) years old. Among them, 7 cases complained of painless hematuria and 9 cases were asymptomatic. Three cases underwent preoperative MRI examination, 19 patients underwent preoperative enhanced CT examination, and 1 patient underwent both MRI and enhanced CT examination. MRI examination showed renal lobulated and other T1 mixed with T2 signals, the boundary was not clear, and DWI showed obvious restricted diffusion. The tumor was located on the left side in 15 cases and on the right side in 8 cases. Preoperative diagnosis was made by fine needle aspiration biopsy in 1 patient, and specimens were obtained by flexible ureteroscope in 2 patients. No tumor was reported. The preoperative diagnosis of 22 patients was unclear and the nature of the tumor could not be determined. One patient was considered to have urothelial carcinoma by fine needle aspiration. All patients were treated by surgery, including 20 cases of laparoscopic radical nephrectomy and 3 cases of nephroureterectomy with bladder sleeve resection.Results:Postoperative pathological specimens showed yellow-white mass, high-grade invasive urothelial carcinoma invading renal parenchyma. Nine cases were T 3a stage, 14 cases were T 3b stage, and 5 cases were lymph node metastasis. The average postoperative follow-up time was (18.6±6.72)months, 2 patients were lost to follow-up, 8 patients died, and the overall mortality rate was 38.1%. Seven patients died of recurrence or metastasis. There were 3 cases of bladder recurrence and 5 cases of metastasis after operation. Conclusions:Renal parenchymal infiltrating urothelial carcinoma is difficult to diagnose in the early stage, with poor clinical biological behavior and poor overall prognosis. For patients diagnosed with renal parenchymal invasive urothelial carcinoma preoperatively, laparoscopic nephroureterectomy + bladder sleeve resection is recommended.
ABSTRACT
Objective:To evaluate the safety and efficacy of laparoscopic nipple-inserted ureteral bladder reimplantation in the treatment of ureteral stricture in kidney recipients.Methods:Two patients with ureteral stenosis after kidney transplantation who underwent laparoscopic nipple-inserted ureteral bladder reimplantation in our hospital in November 2020 and May 2021 were retrospectively analyzed. Case 1, Female, 54 years old, the patient found mild hydronephrosis in the transplanted kidney 2 years before the operation. Ultrasound showed aggravated hydronephrosis 1 week before the operation, and the width of the renal pelvis was 2.9 cm. Nephrostomy was performed before the operation, and antegrade radiography showed that the ureteral anastomosis was narrow, about 2 cm in length, and the grade of ureteral stenosis in the transplanted kidney was grade 3. Case 2, Male, 56 years old, the patient was previously diagnosed with transplanted kidney hydronephrosis, ureterolithiasis and ureteral stricture, and had undergone percutaneous nephrolithotripsy for transplanted kidney and balloon dilatation for ureteral stricture. However, the hydronephrosis and calculus of the transplanted kidney recurred. One month before the operation, due to sudden anuria, a nephrostomy was performed in our hospital. Ultrasound indicated that the transplanted renal pelvis was dilated, and the width of the renal pelvis was 3.1 cm. The grade of ureteral stricture of the transplanted kidney was grade 3. Both patients underwent transabdominal laparoscopy to dissociate and disconnect the ureter, and performed ureteral papillaplasty outside the abdominal cavity to complete ureteral reimplantation. Data on operation time, intraoperative blood loss, intraoperative and postoperative complications, and postoperative follow-up data were collected.Results:Both operations were successfully completed. The operation time was 145 and 180 minutes respectively. The intraoperative blood loss was 30 ml and 50 ml, respectively. The patient had no postoperative complications, and the renal function recovered compared with before. The double J tube was removed 12 weeks after the operation, and ultrasound showed that the width of the renal pelvis recovered to 0.8 cm and 1.1 cm respectively. The two patients were followed up for 18 and 12 months, respectively, and no recurrence of hydronephrosis was found.Conclusions:Laparoscopic nipple-inserted ureteral bladder reimplantation is a safe and effective method for the treatment of allograft ureteral stenosis, which has the advantages of minimally invasive, faster recovery, and fewer complications.
ABSTRACT
Objective:To study the optimal surgical timing of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) for acute cholecystitis.Methods:A retrospective analysis of the clinical data of patients with acute cholecystitis who were treated at Zhengzhou Central Hospital Affiliated to Zhengzhou University from April 2016 to October 2020 with initial PTGBD followed by LC. These patients were divided into three groups according to the time intervals between LC with PTGBD. Patients who underwent LC 3~4 weeks after PTGBD were in the short interval group ( n=67); patients who underwent LC 5~8 weeks after PTGBD were in the intermediate interval group ( n=78); and patients who underwent LC>8 weeks after PTGBD were in the long interval group ( n=73). The baseline and perioperative data of the three groups were compared. Results:In 218 patients, 97 were males and 121 were females, aged (72.1±8.4) years. Before LC, the gallbladder wall in the short interval group (4.77±0.62) mm was significantly thicker than that in the intermediate interval group (3.85±0.34) mm and the long interval group (3.81±0.25) mm (all P<0.05). Intraoperative blood loss in the intermediate interval group was significantly less than that in the short interval group ( P<0.05). The operation time, conversion to laparotomy, placement of drainage tube, postoperative hospital stay and total hospitalization expenses in the intermediate interval group were significantly better than those in the other two groups (all P<0.05). The incidence of complications in the intermediate interval group was significantly lower than that in the short interval group [2.56% (2/78) vs. 14.93% (10/67)], and the long interval group [2.56% (2/78) vs. 12.33% (9/73), all P<0.05]. Conclusion:The best timing for sequential LC after PTGBD in acute cholecystitis was shown in this study to be 5 to 8 weeks after PTGBD.
ABSTRACT
Objective:To analyze the learning effect of laparoscopic radical cystectomy(LRC)+ modified ileal conduit(MIC).Methods:From 2014 to 2019, 42 patients underwent MIC and their clinical data was retrospectively analyzed. 34 operations were performed by surgeon 1 and 8 operations by surgeon 2. We divided the 34 patients of surgeon 1 into three groups according to their surgical sequence (group A, 1st to 12th; group B, 13th to 23th; group C, 24 th to 34 th), the 8 cases of surgeon 2 was regarded as group D. The history of abdomen surgery in the 4 groups were 0, 1, 4, 3 cases, respectively ( P<0.05). There was no significant difference of the other baseline characteristics, such as age, BMI, American Society of Anesthesiologists. Then we compared several variables between the 4 groups like operation time, time of ileal conduit construction, blood loss, complication rate, lymph node yield, surgical margin, etc. The key steps of the MIC included isolating terminal ileum when the mesentery was transilluminated, performing end-to-end reflux ureterointestinal anastomosis after the efferent loop was fixed, closing the rent of the retroperitoneum. Results:All operations were performed intracorporeally with no transition to open surgery. The operative time for group A, B, C were 330.0(320.0, 360.0)min, 300.0(250.0, 308.0)min, 270.0(216.0, 324.0)min, respectively ( P =0.010). The time of ileal conduit construction of the 3 groups were 136.5(131.3, 147.5)min, 92.0(79.0, 119.0)min, 79.0(72.0, 115.0)min, respectively ( P <0.001). In addition, the difference of the two variables above between A and B, A and C groups separately reached statistical significance ( P<0.05), while the difference between B and C groups did not ( P>0.05). Other variables, such as blood loss, complication rate, lymph node yield, surgical margin, between the 3 groups reached no statistical significance ( P>0.05). The operative time of group D was 420.0(350.0, 450.0)min, and it reached statistical significance ( P<0.05) when compared with group A. There were no significant differences in other variables, such as blood loss, complication rate, lymph node yield, surgical margin, among the 2 groups ( P>0.05). Conclusions:The learning effect of LRC+ MIC was obvious. When surgeon volume increased, the operative time decreased significantly. Variables like estimated blood loss and complication rate of the 2 surgeons did not reached significant difference, which indicated reproductivity and safety of this procedure.
ABSTRACT
BACKGROUND: Surface electromyogram signal is often used for qualitative analysis of muscles in the process of autonomic balance recovery after unexpected slips, but there is little research on the response characteristics of muscle force. OBJECTIVE: By the combination of gait analysis and simulation technology to study the muscle force response characteristics of the slipping leg when an unexpected slip of the heel occurs during walking straightly. METHODS: Five healthy subjects were recruited, wearing shoes uniformly, and asked to walk normally on two different straight footpaths (dry oil-free and oil-coated paths). The Vicon motion system and AMTI force measuring platform were used to collect the motion data. Based on the AnyBody Modeling System, a human musculoskeletal model matching with the subjects was established. The model was driven by the motion data, and the data of muscle force were collected and analyzed. RESULTS AND CONCLUSION: The recovery time after an unexpected slip was 15%-45% of a gait cycle and the single support phase was shortened. In the course of autonomic recovery, the muscle strength of the semitendinosus was increased by 25.6% (P < 0.05), and the muscle strength of the short head of biceps femoris increased by 14%. The maximum muscle strength of the medial gastrocnemius increased from 8.4 N/kg to 13.6 N/kg, and that of the lateral gastrocnemius increased by 17.4%. These findings indicate that: in the process of recovering the balance after unexpected slips, the semitendinosus, biceps femoris, gastrocnemius and gastrocnemius produce great muscle force, and meanwhile, the time of single support phase is shortened, so as to quickly transfer the gravity of human body from the sliding leg to the dragging leg and keep the body balance. After the balance recovery from the slip, the human body will make a prediction in the later period of the swing phase to prevent the slip again.
ABSTRACT
Objective@#To detect the expression of matrix metalloproteinase-3 (MMP-3) in serum and gingival crevicular fluid in patients with rheumatoid arthritis (RA) and its correlation with chronic periodontitis (CP).@*Methods@#From March 2017 to July 2018, 26 patients with RA and CP [CP+RA group, (54.9±6.5) years old, 4 males and 22 females], 22 patients with RA only [RA group, (49.6±11.7) years old,5 males and 17 females] in the Department of Rheumatology and Immunology, Shengjing Hospital Affiliated to China Medical University, 22 patients with simple CP in the Department of Stomatology, Shengjing Hospital Affiliated to China Medical University [CP group, (51.4±12.5) years old, 8 males and 14 females] and 18 generally healthy controls in Physical Examination Center of Shengjing Hospital Affiliated to China Medical University [group H, (49.4±9.1) years old, 8 males and 10 females] were recruited. There were no significant differences in age and sex ratio amongst 4 groups. Patient′s general status, probing depth (PD) , clinical attachment loss (CAL), sulcus bleeding index (SBI), simplified calculus index (CI-S) and simplified debris index (DI-S) were recorded in 4 groups. Samples of serum and gingival crevicular fluid were collected from patients of each group, and the expression levels of MMP-3 in serum and gingival crevicular fluid samples were detected by using enzyme-linked immunosorbent assay. Erythrocyte sedimentation rate, rheumatoid factor, anti-cyclic citrulline peptide antibody and C-reactive protein were detected in the serum of subjects in RA group and CP+RA group. Correlation analysis was conducted between MMP-3 expression level and periodontal indices amongst 4 groups. The results were statistically analyzed using the SPSS 20.0 software package.@*Results@#The indices of CAL [(4.12±1.13) mm], SBI (2.58±0.64) and DI-S (2.65±0.69) in CP+RA group were significantly higher than indices of CAL [(3.00±0.00) mm], SBI (2.59±1.05) and DI-S, (2.36±0.49) in CP group (P<0.05); The expression levels of MMP-3 in serum samples of CP+RA group [(1 1645.6±6 903.4) μg/L] and CP group [(9 337.0±6 719.0) μg/L] were significantly higher than that of RA group [(2 389.9±1 320.3) μg/L] and H group [(1 493.5±292.1) μg/L] (P<0.05). The expression level of MMP-3 in gingival crevicular fluid samples of CP+RA group [(164.4±45.3) μg/L] was significantly higher than that of CP group [(84.6±92.5) μg/L], RA group [(49.0±18.1) μg/L] and H group [(20.4±6.3) μg/L] (P<0.05), respectively. The erythrocyte sedimentation rate, rheumatoid factor and anti-cyclic cirullinated peptide antibodies levels in the CP+RA group were significantly higher than those in the RA group (P<0.05). The expression level of MMP-3 in serum is positively correlated with PD (r=0.45, P=0.04) and the expression level of MMP-3 in gingival crevicular fluid is positively correlated with CAL (r=0.58, P<0.01).@*Conclusions@#The levels of MMP-3 in serum and gingival crevicular fluid of patients with RA and CP were significantly increased. MMP-3 may be associated with the development of CP and RA.

Objective To discuss the effect and value of wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy as urinary diversion after radical cystectomy.Methods The clinical data of 12 cases(7 males and 5 females)with bladder cancer during January 2016 and September 2017 were retrospectively analyzed.The median age was 77 years (range 75-83),and the course of the disease was 5 days to 2 years.11 cases had gross hematuria,5 cases had frequent and urgent urination,1 case had lower abdominal pain,and 1 case had no obvious clinical symptoms.9 cases had a history of transurethral prostatic resection.8 cases had a complication of hypertension,5 cases had a complication of diabetes,7 cases had a complication of cardiovascular and cerebrovascular diseases,and 6 cases had a complication of anemia.The ASA level was 3 in 9 cases and was level 4 in 3 cases.All the patiants were diagnosed of bladder urothelial carcinoma by biopsy.There were 8 cases with T3 tumor and 4 cases with T4.All the patients underwent laparoscopic radical cystectomy under general anesthesia,and wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy was used for urinary diversion.Take a segment of 3-5 cm wide pedicle omentum,which is covered from the distal end of the ureter to the end,and use a 4-0 absorbable line to fix the omentum and ureteral outer membrane,and then perform ureterocutaneostomy.The incidence of postoperative anastomotic stenosis,hydronephrosis and wound infection were observed.Results All the operations were performed successfully without obvious operative complications.The mean operating duration was125 (95-217) mins,estimated volume of blood loss 120 (50-600)ml.5 days after surgery,1 patient developed incision infection,which was cured by strengthening anti-infection drug therapy and wound dressing.No complications such as urinary fistula,intestinal fistula and peripheral hernia occurred.No death was reported during perioperative period.Single J tube was removed 1-3 months after surgery.Within a follow-up of 12 (3-23) months,1 case died of cerebral infarction 3 months after surgery,1 case occurred papilla light constriction without special treatment,no ureteral stenosis and necrosis cases and there were no cases of hydronephrosis.All the patients were satisfied with the quality of life after surgery.Conclusions Wrapping ureter by a pedicled gastrocolic omentum flap during cutaneous ureterostomy is simple,safe and effective as urinary diversion after radical cystectomy.
ABSTRACT
Objective To compare perioperative outcomes and complications between intracorporeal and extracorporeal orthotopic ileal neobladder after laparoscopic radical cystectomy (LRC) from one center.Methods We retrospectively analysis patients' clinical and follow-up data who underwent laparoscopic radical cystectomy (LRC) in our hospital from January 2011 to May 2017,of whom 25 cases underwent intracorporeal orthotopic ileal neobladder (ICIN) and 20 cases underwent extracorporeal orthotopic ileal neobladder (ECIN).The patients' characteristics,perioperative data,postoperative pathological results,postoperative complications and oncologic outcomes were compared and analyzed.The mean age of ECIN group was (59.9 ± 10.5)years,mean BMI was (24.7 ±3.3)kg/m2,the ASA level was less than Ⅱ in 19 cases and level Ⅲ in 1 case,the mean preoperative CCI was 4.5 ± 1.6,3 patients got preoperative neoadjuvant chemotherapy.The mean age of ICIN group was (59.0 ± 9.8) years,mean BMI was (25.3 ±4.3)kg/m2,the ASA level was less than Ⅱ in 25 cases and no level Ⅲ,mean preoperative CCI was 4.0 ±1.3,3 patients got preoperative neoadjuvant chemotherapy.There was no statistical difference between the two groups in patients' characteristics.All operations were performed under general anesthesia.After LRC was accomplished,an additional 12 mm trocar was placed 1 cm crania to the pubic symphysis for EndoGIA in ICIN group.An ileal segment 60 cm long was isolated 25 cm proximal to the ileocecum.The continuity of the small bowel was restored with side to side anastomosis.The proximal 10 cm was moved to the distal end of the ileal segment for the right isoperistaltic afferent limb,and the remaining proximal 10 cm ileal segment was reserved for the left isoperistaltic afferent limb.Then,the remaining length of the 40 cm ileal segment was detubularized along its antimesenteric border.The anterior wall of the neobladder was folded forward and the free edges were sutured to achieve a spherical configuration.After single J ureteric stents were inserted into the ureters,the urethra and ureters were sutured with neobladder successively.For ECIN,the ileal segment is removed via a midline laparotomy below the umbilicus 5-10 cm.The construction method of neobladder was the same with ICIN group.Results All 45 cases were successfully operated.There was no statistical difference between ICIN group and ECIN group in operation time [(374.2 ± 74.6) min vs.(360.3 ±83.6)min,P =0.557] and extraction time of pelvic drainage tube[(12.5 ±5.9)d vs.(11.8 ±4.5)d,P =0.686].Patients in the ICIN group had less intraoperative blood loss [(186.0 ± 140.3)ml vs.(272.0 ±110.7) ml,P =0.030],shorter oral intake time [(4.2 ± 2.2) d vs.(6.1 ± 1.6) d,P =0.002],shorter postoperative hospital stay [(13.7 ± 4.2) d vs.(19.9 + 7.6) d,P =0.001].There was no significant difference in the early postoperative complications (P =0.345).The median follow-up time of ICIN group and ECIN group were 30 months and 52.5 months,respectively.The day-time and night-time continence rate were 97.4％ and 86.8％ respectively in the first year after surgery without significant difference.A total of 6 patients suffered distant metastasis,of whom 4 patients suffered multiple metastases,1 case bone metastases and 1 case pelvic lymph node metastasis.Seven patients died,five of whom died of tumor recurrence or metastasis.There was no statistical difference between the two groups in cancer specific survival rates (P =0.644) and recurrence free survival rates (P =0.981).Conclusions Comparing with extracorporeal orthotopic ileal neobladder,intracorporeal orthotopic ileal neobladder has advantages of less blood loss and faster intestinal function recovery,without significantly increased operative time and complications.No significant difference was found in the function of neobladder and oncological outcomes.Randomized controlled trial with large sample and long-term follow-up is needed to verify the advantages of intracorporeal neobladder construction.
ABSTRACT
Objective To discuss surgical tips and techniques of laparoscopic radical cystectomy in the female.Methods We retrospectively reviewed 29 females who underwent laparoscopic radical cystectomy between Feb.2008 and Mar.2017.The median age was 64 years (range 37-83 years),and the median BMI was 24.7 kg/m2 (range 12.1-31.2 kg/m2),and the median CCI was 3 (range 2-9).No distant metastasis was identified by bone scans,chest X-ray and sonography.Preoperative pathology were non-muscular infiltrating bladder cancer in 19 patients and muscular infiltrating bladder cancer in 10 patients by cystoscopic biopsy.Surgical method:under general anesthesia,the patients were placed in lithotomy position.A 5-port transperitoneal approach was used.Under laparoscopy,the suspensorium ligament of ovary was dissected and cut at lateral to the fimbriae of uterine tube,then the ureter was divided and umbilical artery was managed.The broad ligament of uterus was divided.Afterwards,the Douglas'pouch was opened and the fornix of vagina was cut transversely.Then,the endopelvic fascia was divided.The bladder was excised with the female reproductive organs together.If the female reproductive organs were decided to preserve,the dissection was performed along the space between bladder and uterus or vagina.Frozen section of urethra end andthe distal ureter were then obtained.The resected tissues were removed through the vagina,and then vagina was closed.Urinary diversion consisted of orthotopic ileal neobladder in 9 patients,ileal conduit in 14 patients,ureterostomy in 4 patients.All urinary tracts were removed for two cases due to renal function loss before surgery.Results Mean total operative time was 315 mins (ranged from180 mins to 420 mins).Estimated blood loss was 299 ml (ranged from 10 ml to 1 500 ml).Complications occurred in 2 cases.One patient had both vaginal infection and incomplete intestinal obstructionand the other had vaginal infection alone.No patients died in perioperative period.At a median follow up of 36.8 months (ranged from 2 to 110 months),24 patients (82.8％)were alive without recurrences,1 (3.4％) had metastasis in lymph nodes and 4 (13.8％) died.Conclusions Laparoscopic radical cystectomy in the female is technically feasible.Knowing female pelvic anatomy and grasping the techniques conduce to optimize the tips of the surgery and reduce complications.
ABSTRACT
Objective To explore the perioperative outcomes and safety of enhanced recovery after surgery (ERAS) in laparoscopic radical cystectomy (LRC).Methods We retrospectively evaluated outcome of 10 LRC patients on ERAS protocol from May 2017 to October 2017,and 39 LRC patients on conventional recovery after surgery(CRAS) protocol from July 2015 to November 2016.There were (60.9 ±11.4) years and (63.7 ± 12.1) years in ERAS group and CRAS group respectively(P =0.514);(25.5 ±2.7) kg/m2 and (24.4 ± 3.6) kg/m2 with body mass index (P =0.375).Both of the median of charlson comorbidity index (P =0.931) and American Society of Anesthesiologists score (P =0.254) were 2 There was no statistical significance between the two groups for type of urinary diversion and preoperative laboratory studies (P ＞ 0.05).Patients' perioperative outcomes,early (30-day) complications and postoperative readmission rate were compared.Results The ERAS group had less intraoperative crystalloid infusion [(950.0 ± 474.3) ml vs.(1 797.4 ± 448.1) ml,P ＜ 0.001],faster removed gastric tube (0 d vs.4 d,P ＜0.001),and shorter passing flatus time [(1.6 ± 0.8) d vs.(2.9 ± 1.4) d,P =0.006] than the CRAS group;however,no difference was found in terms of intraoperative colliod infusion [(1 110.0 ± 331.5)ml vs.(1 117.9 ± 397.9) ml,P =0.954].No patients from either group required conversion to open surgery.There was no significant difference between the two groups for operative time (P =0.311),estimated blood loss (P =0.073),drain days (P =0.681),postoperative hospital stay (P =0.509),overall blood transfusion (P =1.000),intensive care unit stay (P =1.000) and tumor characteristics (pathological stage,histology,nodes removed,positive nodes,lymph node-positive patients,positive surgical margins).The 30-day postoperative complications were documented in 5 (50％)and 23 (59％)patients in groups ERAS and CRAS (P =0.878),respectively.And the most common complication were minor complications (Clavien-Dindo grade 1 and 2) in both groups (100.0％ vs.86.9％,P =0.729).The 30-day readmission rate was 20.0％ (2 patients) in ERAS group and 10.3％ (4 patients) in CRAS group with no statistical significance(P =0.588).Conclusions Our ERAS protocol expedited bowel function recovery after RC and urinary diversion without increasing in 30-day complications compared with CRAS.The key of implement ERAS pathway is to explore and develop their own protocol conformed to their medical treatment enviroment.

Objective To summarize the characteristics of IgG4 related disease (IgG4-RD),and to avoid unnecessary surgical procedures due to misdiagnosis.Methods Retrospective analysis of the clinical data of one case of IgG4 related disease involving the renal pelvis in our hospital,and the clinical features of IgG4 related disease involving the renal pelvis were reviewed and discussed.A 56-year-old man presented with microscopic hematuria,CT showed right renal pelvis and ureteral wall thickening,local soft tissue density,post contrast CT showed low-density renal pelvic mass and the wall of the ureter-pelvic was irregularly thicken,indicating renal pelvic cancer and lymph node metastasis.PET-CT (18F-FDG) findings indicated that the renal pelvic mass was a malignant tumor,because the glucose metabolism was very high.The preoperative diagnosis was retroperitoneal lesion,suspecting renal pelvic carcinoma or lymphoma.The patient underwent 3D laparoscopic nephroureterectomy with out preoperative biopsy.During operation,we found extensive enlargement of the right renal portal and retroperitoneal lymph nodes,including that the renal portal and the renal pelvis mass had a serious adhesion to the vena cava and renal arterial vein.Results Postoperative pathology results revealed lymphatic tissue hyperplasia and germinal center formation.Immunohistochemical staining showed that most plasma cells positive expression of IgG4 (IgG4 ＞ 40％,IgG4 ＞ 100/HPF),reactive hyperplasia of lymph node,considering the IgG4 related diseases.Serum IgG4 level was 15.2 g/L (0.03-2.01 g/L)after operation.Combined with serological examination,IgG4 related disease was confirmed.There was no evidence of IgG4-related disease at any other site during the follow up period,thereby obviating the need for any additional therapy.Conclusions IgG4 related disease is a novel clinical disease entity characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4-positive plasma cells,which leads to the enlargement of the organ or nodular/proliferative lesions.The disease can be revealed as a soft tissue tumor of the renal pelvis and be misdiagnosed as malignant tumor.Surgical intervention could be avoided according to the correct diagnosis.
ABSTRACT
Objective To investigate the expression levels of adiponectin and visfatin in the gingival crevicular fluid (GCF) and serum of patients with obesity and chronic periodontitis.Methods The study included 80 patients.Among them,20 were healthy controls (H group),20 had periodontitis (CP group),20 had obesity (OB group),and 20 had both obesity and periodontitis (OB+CP group).The patients' baseline information and clinical parameters were recorded,and the GCF and serum were collected.The concentration of adiponectin and visfatin in the GCF and serum were then assayed using ELISA.Use the SPSS 17.0 software package for statistical analysis.Results The concentration of adiponectin in the serum of the CP group,the OB group,and the OB+CP group were significantly lower than that of the H group (P ＜ 0.05).The concentration of adiponectin in the serum of the OB+CP group was lower than that of both the CP and OB groups (P ＜ 0.05).The concentration of adiponectin in the GCF of the CP group,the OB group,and the H group were higher than that of the OB+CP group (P ＜ 0.05).The concentration of adiponectin in the GCF of the CP group,the OB group,and the H group were lower than that of the OB+CP group (P ＜ 0.05).Conclusion Obesity may aggravate the destruction of periodontal tissue by inhibiting the expression of adiponectin and promoting the expression of visfatin.
ABSTRACT
Objective To assess the perioperative safety and postoperative function of the pure 3-dimensional laparoscopic cystectomy and urinary diversion (P3DLC-UD).Methods From April 2014 to July 2015,P3DLC-UD was performed in 15 patients diagnosed with the bladder cancer in our center (orthotopic ileal neobladder for 8 cases and ileal conduit for 7 cases).Perioperative data,postoperative continence and overall survival rate were retrospectively analyzed.Results Fifteen patients underwent P3DLC-UD successfully as planned,with 8 patients underwent orthotopic ileal neobladder and 7 patients underwent ileal conduit.In neobladder group,the operative time were 300-600mmin (mean 428 min),estimated blood loss were l 00-400ml (mean 210mml),and dissected lymph nodes were 11-29 (mean 16).One patient required blood transfusion (800ml) and one patient was diagnosed of constipation.The patients were followed up for a median period of 10 months (3-15 months).The renal function was normal with serum creatinine of 36.4-99.0 μ mol/L (mean 77.3 μmol/L).One patient died of intestinal obstruction and 8 patients had no recurrence in neobladder group.As to postoperative continence,only 2 patients demanded 1 pad at daytime,while all patients needed 1 pad at nighttime.In ileal conduit group,the operative time were 300-390 min (mean 354 min),estimated blood loss were 50-400ml (mean 190ml),and dissected lymph nodes were 9-41 (mean 22),while 9-41 (mean 19) lymph nodes were got for all 15 cases.Two patients were diagnosed with urinary infection after the surgery.The patients were followed up for a median period of 5 months (1-9 months).The renal function was normal with serum creatinine of 36.4-74.0 μmol/L (mean 60.8 μmol/L).One patient died of cerebral infarction,and 1 patient found distant metastases in lung and died of cancer after chemotherapy during the follow-up period.There were no recurrent tumors of the other 5 patients in ileal conduit group.Conclusions P3DLC-UD is safe and feasible.More extensive,longer-term randomized trials are required to comprehensively assess the appropriateness and potential of this technique.
ABSTRACT
Objective To investigate the method of controlling leg length in total hip arthroplasty for CroweⅣtype devel?opmental dysplasia of the hip. Methods From February 2006 to February 2011, primary total hip arthroplasty were performed in 11 patients (3 males and 8 females, aged 54 year and ranged from 45 to 65 years) with CroweⅣtype developmental dysplasia of the hip using subtrochanteric femoral osteotomy. Leg length was measured in the method of preoperation plan combining with mea?surement in the course of operation. Five hips were involved in left side, 6 in right side. The average leg length discrepancy were 3.5 cm (ranged, 1.8-6.0 cm). All patients have lumbosacral pain. Clinical and radiographic characteristics were retrospectively re?viewed at the 3, 6 and 12 months after operation. Outpatient follow?up was conducted every year. The lumbosacral pain and degree of patient satisfaction were recorded. Moreover, leg length discrepancy, the bone union, prosthesis subsidence, and the hip Harris score were evaluated. Results Average follow?up was 4.5 years (3-8 years). The average length of resected bone was 2.2 cm (1.5-4.2 cm). The average leg length discrepancy were 1.0 cm (ranged,-1.5-1.5 cm). Lumbosacral pain of 8 patients was eliminated and slight pain was retained in 3 patients. Two patients were satisfied with the result of operation and 9 were extremely satisfied. No nerve injury and nonunion occurred. At the final follow?up, the mean Harris score improved from 45 ± 7.6 before operation to 93±6.6 (P<0.05). The mean union time was 5 months after operation (3-12 months after operation). The prosthesis subsidences were found in one case at the five years after operation and 1 case at the seven years after operation and with subsiding height of 3 mm and 6 mm respectively. No loosening and infection were found in all patients. Conclusion In treating patients with CroweⅣtype developmental hip dysplasia by THA, the length of resected subtrochanteric femoral should be conducted according to pa?tient's tolerance to pain reduced by leg extension. Therefore, the leg length is facilitated to improve the function of joint and to de?crease symptoms reduced by leg extension.
ABSTRACT
Objective To investigate the indications and mid-term outcomes of periacetabular osteotomy through ilioinguinal approach for developmental dysplasia of the hip (DDH) in middle-aged (40-50years old) adult patients.Methods Data of 10 adult patients who had undergone periacetabular osteotomies through ilioinguinal approach for DDH from August 2005 to February 2010 were retrospectively analyzed.There were 7 females and 3 males,aged from 40 to 47 years (average,42 years).Bilateral hips were involved in 3 patients,and unilateral hip was involved in 7 patients.Before this hospitalization,1 patient had received Chari osteotomy,and 1 had received hip-shelf procedure.According to the T(o)nnis classification,3 hips were classified as Grade 0,5 as Grade Ⅰ and 2 as Grade Ⅱ.The Shenton line was discontinuous in 6 hips.The average lateral center-edge angle was 3.50°±4.88°; the average anterior center-edge angle was 1.80°±5.07°; the average acetabular index angle was 18.20°±3.01°; the average femoral head extrusion index was 31.30％±4.37％; the average Harris hip score was 67.40±7.75.Changes of the indexes mentioned above were observed during the whole period of follow-up.Results All patients were followed up for 10 to 76 months (average,37 months).The T(o)nnis grade improved in 2 cases,from preoperative Grade Ⅰ and Grade Ⅱ to Grade 0 and Grade Ⅰ at final follow-up,respectively.At final follow-up,the Shenton line was discontinuous in 2 hips; the average lateral center-edge angle improved to 30.40°±3.31°,the average anterior center-edge angle improved to 29.50°±3.03°,the average acetabular index angle decreased to 4.50°±2.55°,the average femoral head extrusion index decreased to 9.90％±4.33％; the average Harris hip score increased to 84.10±4.07.The major complications included 3 cases of lateral femoral cutaneous nerve palsy which recovered in 4 to 6 months,and 1 case of iliac fossa hematoma which disappeared in 2 weeks.Conclusion With more strict surgery indication and more meticulous manipulation,periacetabular osteotomy through ilioinguinal approach can achieve satisfactory results in the treatment of DDH in middle-aged adults,which can increase hip joint congruence,relieve hip symptom and delay progression of osteoarthritis.
ABSTRACT
BACKGROUND:Changing the acetabular orientation is the best method for the treatment of acetabular dysplasia, and Bernese periacetabular osteotomy is one of the most commonly used and successful treatment methods. OBJECTIVE:To review and analyze the operation indication, surgical technique and influencing factors of Bernese periacetabular osteotomy for better clinical application. METHODS:The PubMed database, Elsevier database and Springer database were retrieved for related articles published before December 2012 with the key words of“Bernese osteotomy, Ganz osteotomy, periacetabular ostetomy”. The articles that related to the clinical application of Bernese periacetabular osteotomy in patients with acetabular dysplasia were enrol ed in this study. Repetitive studies and Meta analysis were excluded. And the analysis emphasis was put on the operation indication, surgery technique and influencing factors of Bernese periacetabular osteotomy. RESULTS AND CONCLUSION:A total of 483 articles were screened out after primary computer-based online research. And according to the exclusion criteria, 43 articles were selected for review. Bernese periacetubular osteotomy was performed through polygonous osteotomy around the acetabula by modified Smith-Peterson approach. The surgical technology was improved gradual y, but the major osteotomy procedures never changed, only the soft tissue release method was modified. The direct factors that influence the surgical effect of Bernese periacetabular osteotomy are the degree of radiographic hip degeneration and dysplasia. In the future, with the in-depth understanding of hip deformity, the operation indication and technique of Bernese periacetabular osteotomy wil also developed.
ABSTRACT
XIAP(X-linked inhibitor of apoptosis protein)is one of the most important members of IAPs family.It inhibits cell apoptosis mainly by inhibiting the caspases activation and interfering with other apoptotic pathway,which plays a critical role in tumor development.Recently,genetic therapy targeting on XIAP for malignant tumors has deeply developed.Research on XIAP as a malignant and prognositic indicator is ongoing.
ABSTRACT
Objective To analyze the effect of acromio-humeral interval on the occurrence of subacromial impingement syndrome (SIS) after the clinical application of clavicular hook plate in acromioclavicular joint dislocation (Tossy Ⅲ). Methods From July 2005 to October 2008, 63 cases of acromioclavicular joint dislocation (Tossy Ⅲ) were treated with clavicular hook plate. There were 48 males and 15 females with an average age of 33.6 years (range, 21-53 years). The relationship of the acromio-humeral interval (AHI)were analysed between the two groups by X-ray measurement. The AHI and plate-humeral interval (PHI)were measured on X-ray film to detect difference between the two groups. Results After the operation, all t he 63 cases were divided into two groups according the occurrence of SIS. There were 14 cases in the group of SIS and 49 cases in the group without SIS. The mean follow-up was 12.2 (average, 6-15) months.The average AHI of was (8.5±2.1) mm and (9.7±2.6) mm in the group of SIS and the group without SIS respectively. The difference between the two groups was statistically significant. The average PHI of the group of SIS and the group without SIS was (6.1±2.8) mm and (6.8±2.4) mm respectively. There was no difference between the two groups. After removal of the clavicular hook plate, the clinical sign disappeared in the group of SIS. According the Karlsson scoring system, the excellent and good rate of the shoulder function was 100%. Conclusion The occurrence of SIS after the clinical application of clavicular hook plate has related to the width of the subacromial interval. The syndrome could be treated by the removal of clavicular hook plate.
