OBJECTIVETo evaluate and compare the value of dynamic multiple pelvic angiography and pelvic four-contrast defecography in the diagnosis of functional defecation disorder.
METHODSFrom September 2014 to July 2015, a prospective controlled trial was carried out in Chengdu Anorectal Hospital. A total of 32 patients met the inclusion criteria of functional defecation disorder simultaneously underwent pelvic four-contrast defecography and dynamic multiple pelvic angiography. The diagnostic results of these two methods were compared.
RESULTSThe absolute values of anorectal angle and level of perineum, peritoneum and bladder from rest to defecation were (29.6±13.6)°, (26.2±14.2) mm, (55.5±25.6) mm and (28.9±16.5) mm in dynamic multiple pelvic angiography, and (24.6±5.8)° (18.7±10.6) mm, (34.5±18.4) mm and (19.2±11.8) mm in pelvic four-contrast defecography respectively, whose differences were statistically significant (P = 0.026, 0.022, 0.000, 0.011 respectively). The diagnostic rate of pelvic peritoneal hernia was 93.8%(30/32) and 68.8%(22/32) in dynamic multiple pelvic angiography and pelvic four-contrast defecography respectively with significant difference(P=0.011).
CONCLUSIONDynamic multiple pelvic angiography has significant advantage in the diagnosis of pelvic peritoneal hernia, and can provide a more objective basis for the diagnosis of functional defecation disorder.

Objective To formulate the quantitative grip strength training program for application in the postoperative patients with autogenous arteriovenous internal fistula,and to evaluate its effect on the mat-uration and initial use of autogenous arteriovenous internal fistula.Methods A total of 98 patients with ce-phalic venous radial arterial anastomosis internal fistula formation surgery in Shenzhen Hospital of Southern Medical University from September 2021 to November 2022 were selected as the study subjects by the conven-ience sampling method.According to the follow-up time,they were divided into the observation group (n=41) and control group (n=42).The observation group adopted the quantitative grip strength training for function-al exercise of the limb on the side of internal fistula,while the control group adopted the conventional grip training for functional exercise of the limb on the side of internal fistula.In postoperative 8 weeks,the matura-tion rate of internal fistula,natural blood flow amount of internal fistula,internal diameter of cephalic vein,pre-pump pressure used in the initial stage of internal fistula and the incidence rate of internal fistula complica-tions were evaluated in the two groups.Results Compared with the control group,the maturation rate of in-ternal fistula in the observation group was higher (97.6% vs. 83.3%).The inner diameter of cephalic vein and natural blood flow amount of internal fistula in the observation group were larger than those in the control group[(5.24±0.66)mm vs. (4.63±0.59)mm;(1215.38±562.99)mL/min vs. (955.75±341.94)mL/min],the pre-pump pressure used at the initial stage of internal fistula in the observation group was lower than that in the control group[(119.20±19.83)mmHg vs. (135.74±17.07)mmHg],and the differences were statistically significant (P<0.05).Conclusion The quantitative grip strength training could increase the postoperative maturity rate of patients's internal fistula,and is beneficial to the use in the initial stage of internal fistula.
