ABSTRACT
AIM: To investigate the application value of Worst lacrimal probe combined with modified lacrimal duct intubation in anastomosis of complex canalicular laceration.METHODS: Retrospective study. A total of 68 cases(68 eyes)with complex traumatic canalicular laceration treated in the ophthalmology department of the Second Affiliated Hospital of Zunyi Medical University from March 1, 2019 to March 31, 2021 were selected. They were divided into two groups according to the surgical methods, with 36 patients(36 eyes)who were treated with the Worst lacrimal probe to find the broken end of lacrimal duct combined with improved lacrimal duct threading intubation in group A, and 32 patients(32 eyes)who were treated with microscope to find the broken end of lacrimal duct and two-way intubation anastomosis canaliculus intubation in group B. The clinical efficacy, success rate of intraoperative search for the broken end of lacrimal duct, searching time, operation time, the degree of pain, postoperative ocular foreign body sensation and complications were compared between the two groups.RESULTS: The total effective rate of clinical efficacy in patients of group A was higher than that in group B(94% vs. 38%), the success rate of intraoperative search for broken end of lacrimal duct was higher than that in group B(100% vs. 47%), the searching time and operation time were shorter than those in group B, and the score of pain degree was lower than that in group B(all P<0.05). The postoperative follow-up for 6mo-1a showed that the ocular foreign body sensation score, the incidence of lacrimal punctum rupture and morphological change, and the degree of tear overflow in group A were all lower than those in group B(all P<0.05).CONCLUSION: Worst lacrimal probe combined with modified lacrimal duct intubation for the treatment of complex traumatic canalicular laceration can find the broken end of lacrimal duct more accurately, shorten the operation time, reduce the pain and foreign body sensation of patients, improve clinical efficacy and reduce the incidence of complications.
ABSTRACT
【Objective】 To introduce the key techniques of "one-cut" circumcision, and to compare its clinical efficacy with traditional circumcision. 【Methods】 A retrospective analysis was conducted on 120 cases of circumcision in our center during Jul.2020 and Jul.2022, including 60 cases in the "one-cut" group and 60 cases in the traditional circumcision group. The operation time, postoperative edema time, satisfaction with cosmetics and improvement of sexual life were compared between the two groups. 【Results】 Compared with the tradition group, the "one-cut" group had shorter operation time [(19.2±7.4) min vs. (23.1±1.7) min, P<0.001] , shorter postoperative edema time [(5.5±3.2) d vs. (9.6±5.5) d, P<0.001] , and higher satisfaction with cosmetics [(3.6±0.5) vs. (3.1±0.8), P<0.001)] , but there was no difference in improvement of sexual life between the two groups (P=0.08). 【Conclusion】 "One-cut" circumcision is easy to operate, with short operation time, fast postoperative recovery, neat incision and satisfactory appearance, which is worth popularizing.
ABSTRACT
Objective To evaluate the efficacy of modified abdominal laparoscopy in the repair of complex vesical vaginal fistula after total hysterectomy.Methods The clinical data of 58 cases of urinary bladder and vagina fistula in our hospital from April 2014 to December 2017 were retrospectively analyzed,of which 32 cases were repaired by ordinary abdominal laparoscopy from April 2014 to February 2016 and 26 cases were repaired by modified abdominal laparoscopy from March 2016 to June 2017.On the basis of the original laparoscopy,the modified transabdominal laparoscopy enlarged the free range between the vaginal stump and the bladder,separated the anterior vaginal wall from the bladder completely and dissociated the retrovaginal peritoneum,wrapping around the vaginal stump to make the peritoneum.The median age of ordinary group was 52 (range:33-67)years old,the median course of disease was 12 (range:3-40) months,and the size of fistula was (25.5 ± 10.3) mm.The median age of modified group was 50 (range:37-65) years,the median course of disease was 11.5 (range:3-36) months,and the size of the fistula was (26.3 ± 9.1) mm.The operation time,bleeding volume,the time of hospitalization,the rate of complications and the success rate of the operation were compared.Results The operation time of the two groups was successfully completed.The operation time of the modified group [(164.2 ± 21.2) min] was significantly shorter than that of the common group [(201.4 ± 25.8) min],and the difference was statistically significant (P ＜ 0.01).In the modified group,the cure rate (100.0％,26/26) was higher than that in the normal group (84.4％,27/32,P ＜ 0.05).There was no significant difference in the amount of intraoperative bleeding[50 (10-100) ml vs.55 (5-110) ml],hospitalization time [(9.1 ± 1.7) d vs.(10.0 ± 1.8) d],postoperative infection [19.2％ (5/26) vs.15.6％ (5/32)],urinary incontinence [7.7％ (2/26) vs.9.4％ (3/32)],urinary frequency [15.4％ (4/26) vs.21.9％ (7/32)],intestinal obstruction [3.8％ (1/26) vs.9.4％ (3/32)] between the modified group and common group (P ＞ 0.05).Conclusions The modified transabdominal laparoscopic mode shortens the operation time,and improves the cure rate of the operation.Satisfactory results are recommended for the repair of high complex bladder vagina fistula.
ABSTRACT
@#Objective To compare the reliability of modificatory method and traditional method in preparing ischemic stroke rat model in rehabilitation period.Methods 173 female SD rats were divided into traditional method group(n=63),modificatory method group(n=109) and control group(n=37).In the traditional method group,the thread embolus was inserted through the left external carotid artery(ECA),and then left ECA and pterygopalatine artery(PPA) were ligated.In the modificatory method group,the thread embolus was inserted through the left internal carotid artery(ICA) and only left common carotid artery(CCA) was ligated.In the control group,the thread embolus was not inserted,only CCA was ligated.Results There was no significant difference in neurofunction score between the modificatory method group and the traditional method group(P>0.05).The operating time was significantly shortened(P<0.01) and the survival time was significantly prolonged in the modificatory method group compared with that of the traditional method group(P<0.01).The two-month survival rate was 54.13% in the modificatory method group and 31.75% in the traditional method group receptively,the former was significantly longer than the latter(P<0.01).Conclusion The ischemic stroke model established by modificatory methods is not only precisely and reliable but also save operating time and improve survival rate of the animals compared with the traditional method.The main death causes of animals are large-area cerebral edema and electrolyte imbalance after operation.
ABSTRACT
Objective To evaluate modified retroperitoneal laparoscopic resection of renal cyst. Method Thirty-six patients with renal cyst were treated by modified retroperitoneal laparoscopic resection of renal cyst,summarized the clinic data and follow-up the effect. Results All 36 cases were operated suc-cessfuUy without changing to opening operation,average operation time (50 ± 35)min,no complications oc-curred and no recurrence was found. Conclusions The modified retroperitoneal laparoscopic resection of renal cyst with two 5 mm-trocars and one 10 mm-trocar has less trauma than classic laparoscopic operation. It is one of mini-trauma operation method which is worth to be popularized in clinic.
