ABSTRACT
Objective:To investigate the safety and efficacy of self-made multifunctional endoscopic instrument accessory stent in endoscopic mucosal dissection (ESD).Methods:A total of 80 patients who received ESD in 924th Hospital of Joint Logistic Support Force of Chinese People′s Liberation Army from May 2019 to February 2021 were selected as research object. Random number table method was used to divide patients into control group and experimental group, 40 cases in each group. The experimental group used self-made endoscopic instrument accessory stent, and the control group did not use self-made endoscopic instrument accessory stent. The length of operation, the number of instruments taken by mistake, the number of instruments polluted during operation and the infection of postoperative 3-7 days under the same operation position, operating doctors and nurses were analyzed and compared between the two groups.Results:The incidence of instruments taken by mistake, the incidence of instruments polluted during operation and the infection rate of postoperative 3-7 days were 0.9% (8/856), 1.4% (12/856) and 2.5% (1/40) in the experimental group, which in the control group were 10.8% (96/887), 11.8% (105/887) and 15.0% (6/40) respectively, there were significant differences between the two groups ( χ2=75.92, 75.76, 3.91, all P<0.05). The length of operation in the experimental group was (51.56 ± 2.32) min, and that in the control group was (79.02 ± 2.83) min, the difference was statistically significant ( t=-8.72, P<0.05). Conclusions:When the patients underwent ESD surgery, the self-made multifunctional accessory stent was used to place the required instrument accessory. The length of operation was shorter, the incidence of instruments taken by mistake, the incidence of instruments polluted during operation and the infection rate of postoperative 3-7 days were reduced, the quality of minimally invasive endoscopic surgery was improved.
ABSTRACT
Objective To evaluate the efficacy and safety of modified transurethral plasmakinetic enucleation of prostate (M-TPEP) combined with cystolithectomy in elderly patients with high risk of large volume benign prostatic hyperplasia (BPH) complicated with large urinary bladder calculi. Methods Seventy-one patients with high risk of large volume BPH complicated with large urinary bladder calculi were selected, and the patients were treated with M-TPEP combined with cystolithectomy. The operation time, intraoperative blood loss, hospitalization time, complications, and the maximum urinary flow rate (Qmax), post-void residual volume (PVR), serum potassium, international prostate symptom score (IPSS), quality of life (QOL) score preoperative and postoperative 3 months were recorded. Results Seventy-one patients successfully completed the operation, and no death occurred. The operation time was (75.48 ± 6.51) min, intraoperative blood loss was (82.63 ± 10.08) ml, and postoperative hospitalization time was 5-7 d. Incidence of intraoperative capsule perforation was 2.82% (2/71), incidence of postoperative temporary urinary incontinence was 7.04% (5/71), incidence of urethral and bladder irritation after operation was 8.45% (6/71), and incidence of postoperative wound infection was 2.82% (2/71). The PVR, IPSS and QOL score 3 months after operation were significantly lower than those before operation: (6.89 ± 0.74) ml vs. (205.13 ± 40.08) ml, (2.71 ± 0.45) scores vs. (28.62 ± 3.57) scores and (1.36 ± 0.24) scores vs. (4.93 ± 0.38) scores, the Qmaxwas significantly higher than that before operation: (22.46 ± 2.97) ml/s vs. (5.24 ± 0.43) ml/s, and there were statistical differences (P＜0.01);there was no statistical difference in serum potassium between before operation and 3 months after operation (P＞0.05). Conclusions M-TPEP combined with cystolithectomy has short operation time, quick recovery after operation and low complication rate. It is a proper operative method for the elderly patients with high risk of large volume BPH and large urinary bladder calculi.
ABSTRACT
Objective To study the anti-tumor effect of water extracts from Sophora Moorcroftiana seed(SMSWE) in vivo on mice.Methods S180-bearing mice group were observed.The inhibitory rate of tumor,survival period,indexes of thymus and spleen,the proliferative ability of T lymphocytes were assayed.Results 1.2 and 2.4 g/kg SMSWE could inhibit the growth of S180 tumor in mice and prolonged survival period(P
ABSTRACT
Objective To evaluate the clinical efficacy and safety of retroperitoneal laparoscopic pyelolithotomy in the treatment of intrarenal pelvic staghorn calculus or multiple renal calculi. Methods Fifteen patients(9 males and 6 females)with average age of 40 years old were treated. The diameters of the calculi were from 1.5 cm to 3.7 cm. Three trocars were used in this procedure as rou-tine. The renal sinus was exposed by separating the pelvis from outside to inside until reaching the in-fundibulum of the renal calyx. Then the renal calyx was cut open and the calculus was taken out. Double J stent was placed in the ureter and the incision of pelvis was closed by 3-0 absorbable suture. The drainage tube was pulled out 3-4 d post-operatively according to the drainage quantity. Double J stent was then pulled out 2 weeks after surgery. Results All the 15 procedures were successfully completed. The average operation time was 170 min and the average post-operative hospital stay was 7 d. During the 3-15 months' follow-up, 2 patients had calculus remnants with the size of 0. 2-0.5cm in diameter. Conclusions Retroperitoneal laparoscopic pyelolithotomy provides a minimally inva-sive treatment option in patients with intrarenal pelvic staghorn calculus or multiple renal calculi. It has the advantages of good exposure, little bleeding, small incision and fast recovery.
