ABSTRACT

Objective:To investigate the long-term outcomes of laparoscopic ventral rectopexy (LVR) for obstructive defecation with overt pelvic structural abnormalities.Methods:The retrospective cohort study was conducted. The clinical data of 31 obstructive defecation patients with overt pelvic structural abnormalities who were admitted to the Renji Hospital of Shanghai Jiaotong University School of Medicine from June 2014 to August 2020 were collected. There were 6 males and 25 females, aged 59(range, 32?81)years. All 31 patients underwent LVR through transabdominal approach. Observation indicators: (1) the Cleveland clinic constipation score (CCCS); (2) severity of obstructive defecation; (3) patients assessment of constipation quality of life (PAC-QoL). Follow-up was conducted using telephone interview and outpatient examination up to October 2021. One professional researcher assessed the constipation symptoms and quality of life of patients through outpatient interview or mobile software platform of Questionnaire Star. Measurement data with skewed distribution were represented as M(range), and comparison before and after operation was conducted using the Wilcoxon sign rank test. Results:(1) The CCCS. All 31 patients underwent LVR for the first time and were followed up for 61.8(range, 11.0?87.0)months. The constipation symptoms of the 22 patients were improved. The CCCS of the 31 patients before surgery and at the last follow-up time were 15.8(range, 8.0?26.0) and 10.7(range, 2.0?20.0), respectively, showing a significant difference ( Z=?3.98, P<0.05). (2) Severity of obstructive defecation. The severity scores of frequency of bowel movements, difficult of bowel movements, sensation of incomplete defecation, abdominal distension or pain, time of each bowel movements, daily unsuccessful times of defecation, artificial assisted defecation for the 31 patients were 2.9(range, 1.0?4.0), 3.0(range, 1.0?4.0), 1.9(range, 0?3.0), 0.5(range, 0?3.0), 2.6(range, 2.0?4.0), 2.0(range, 0?4.0), 0.9 (range, 0?2.0) before surgery, versus 1.7(range, 0?4.0), 1.6(range, 0?4.0), 1.2(range, 0?4.0), 0.3(range, 0?3.0), 1.7(range, 0?3.0), 1.4(range, 0?3.0), 0.7(range, 0?2.0) after surgery, respectively. There were significant differences in the frequency of bowel movements, difficult of bowel movements, sensation of in-complete defecation, abdominal distension or pain, time of each bowel movements, daily unsuccessful times of defecation for the 31 patients before and after surgery ( Z=?3.38, ?3.80, ?2.54, ?2.31, ?3.64, ?2.75, P<0.05) and there was no significant difference in the artificial assisted defecation for the 31 patients before and after surgery ( Z=?1.31, P>0.05). (3) PAC-QoL. The score of physical discomfort, satisfaction, worries and concerns, psychological discomfort for the 31 patients were 2.3(range, 1.0?4.0), 3.2(range, 1.0?4.8), 2.2(range, 0.6?4.0), 1.8(range, 0.4?3.9) before surgery, versus 1.6(range, 0?4.0), 2.3(range, 0?4.0), 1.7(range, 0?4.0), 1.3(range, 0?4.0)after surgery, respectively, showing significant differences before and after surgery ( Z=?3.49, ?2.17, ?2.50, ?3.05, P<0.05). Conclusions:The long-term outcomes of LVR for obstructive defecation with overt pelvic structural abnorma-lities are satisfactory. Symptoms as frequency of bowel movements, difficult of bowel movements, sensation of incomplete defecation, abdominal distension or pain, time of each bowel movements and daily unsuccessful times of defecation will be significantly improved after LVR and the constipation quality of life of patients will be improved.

ABSTRACT

PurposeTo explore the gemstone CT with low tube voltage and low concentration contrast medium in evaluating renal artery imaging of preoperative living renal transplantation donor.Materials and Methods Fifty cases of living kidney donor underwent spiral CT angiography of renal artery before operation. The patients were randomly divided into double-low group (25 patients) with 100 kV and Visipaque (270 mg/ml), and control group (25 patients) with 120 kV and Iopromide (370 mg/ml). Image reconstruction of 40% ASiR was used in both groups. The image quality score, CT values of renal arteries, contrast-to-noise ratio (CNR), noise, radiation dose and the amount of contrast agent of the two groups were recorded and compared.ResultsKappa coefifcient analysis showed that the consistency in evaluating image quality between two radiologists was excellent (Kappa=0.82). The CT value of the renal arteries and image quality did not show signiifcant difference between the two groups (t=1.05, 0.07 and 1.62,P>0.05). The CNR, noise and average radiation dose were statistical different between the two groups (t=2.92,-6.95 and-2.21,P<0.05). The contrast medium dosage of double-low group was decreased by 27% when compared with that of the control group.Conclusion Satisfied image quality of renal artery CTA can be obtained with low tube voltage (100 kV) and low concentration contrast medium (270 mg/ml) combined with iterative reconstruction algorithm. It can be used as a routine method in preoperative examination of living renal donors.

ABSTRACT

Objective To study the multidetector CT (MDCT) features of soft tissue hemangiomas.Methods Plain CT,contrast-enhanced CT and CT angiographic findings of 20 patients with soft tissue hemangiomas confirmed by clinical,operative and pathologic data were retrospectively analysed.Results The lesions appeared as soft tissue density on CT and 5 cases with patchy calcification.There were various enhancement after administration of contrast media,net-like vessel enhancement intratumor both arterial and venous phase(12/20),the large supplying arteriae including simple feeding artery(4/12) and multiple feeding arteriae(8/12) could be seen,and varix within the tumors(6/12),no or mild enhancement in other cases(8 cases) on arterial phase,and homogeneous enhancement on venous phase also presented.Conclusion The imaging findings such as shape,size,supplying artery of soft tissue hemangiomas can be showed clearly by MDCT angiography.
