Objective To evaluate clinical remission in patients with small bowel Crohn's disease (SBCD) who have received infliximab(IFX) therapy and to evaluate capsule endoscopy combined with ileocolonoscopy for mucosal healing at 14th week of IFX therapy.Methods Clinical data of 23 SBCD patients who received IFX were retrospectively analyzed.Laboratory indices [routine blood tests,C-reactive protein (CRP)and albumin],Crohn's disease activity index (CDAI),Lewis score (LS),Crohn's disease simplified endoscopic score (SES-CD),side effects and complications were compared before IFX treatment and at 14th week of IFX therapy.Results In 23 SBCD patients,both CDAI and CRP levels significantly decreased (P＜0.01) while body mass index (BMI) and albumin levels increased at 14th week (P＜0.05),compared with those before treatment.The clinical remission rate at 14th week was 91.3％ (21/23).There were 8/23 (34.8％)SBCD patients achieving mucosal healing in small bowel,12/21 (57.1％) in terminal ileum and colon,and 7/21 (33.3％) in both small bowel and colon.Twelve patients achieved both clinical remission and biochemical remission at 14th week and all of them achieved mucosal healing in both terminal ileum and colon (SES-CD ≤ 2).However,there were 5 (41.7％) of them still with small bowel inflammation (LS＞ 135).Conclusion IFX plays a role in promoting clinical remission and mucosal healing in SBCD patients.Mucosal healing of CD patients in terminal ileum and other parts of small intestine are not synchronized.For CD patients with small bowel and colon involved,the evaluation of the whole gastrointestinal tract by capsule endoscopy combined with ileocolonoscopy is recommended on condition that they have no intestinal obstruction or severe stricture.

Objective To study the relationship between jejunal-ileum lesions and terminal ileum lesions of patients with isolated small intestinal Crohn disease, and to compare the clinical and endoscopic features of patients having normal terminal ileum with those having abnormal terminal ileum in isolated small intestinal Crohn disease. Methods The data of patients diagnosed as having isolated small intestinal Crohn disease and successively receiving colonoscopy and small bowel capsule endoscopy in Nanfang Hospital of Southern Medical University from January 2008 to October 2015 were retrospectively analyzed. The patients were divided into normal terminal ileum group and abnormal terminal ileum group according to the result of colonoscopy. The clinical and endoscopic features of the two groups were compared. Results The data of 62 patients were collected, and jejunal-ileum lesions were found in all of the patients under small bowel capsule endoscopy. According to the result of colonoscopy, 40 patients ( 64. 5%) were grouped to the abnormal terminal ileum group and 22 patients ( 35. 5%) to the normal group. The patients in the normal terminal ileum group had a shorter disease duration than those of the abnormal group [ 68. 2%( 15/22) VS 12. 5%( 15/40) , P=0. 021] . The sex and age distribution, smoking history, clinical feature, upper gastrointestinal involvement, perianal lesion, disease behavior, Crohn disease activity index, inflammation markers and nutriture between the two groups had no statistical difference ( P>0. 05) . Conclusion The terminal ileum lesions found by colonoscopy cannot predict small bowel lesions for Crohn disease. Small bowel capsule endoscopy is helpful for the detection of small intestinal lesions in Crohn disease. We should pay more attention to evaluating the small bowel lesions when the patients with Crohn disease have a short duration and normal terminal ileum.

Objective:To investigate the factors affecting the effect of periprostatic nerve block (PNB), establish a prediction model of pain degree, and verify the prediction efficiency.Methods:The clinical data of 314 patients who underwent transperineal prostate biopsy in our hospital from June 2022 to January 2023 were retrospectively analyzed. The median age was 71 (65, 76) years, the median prostate-specific antigen (PSA) was 14.6 (10.70, 24.65) ng/ml, and the median puncture needle number was 21 (19, 23) needles, median prostate volume 45.86 (31.52, 67.96) ml, median body mass index (BMI)24.02(22.97, 25.33)kg/m 2, including 109 patients with a history of diabetes, 90 patients with a history of surgery, and 57 patients with a history of severe trauma. The patients were divided into mild pain group (1-3 points), moderate pain group (4-6 points) and severe pain group (7-10 points) according to the intraoperative visual analogue scale (VAS). According to the clinical characteristics, the factors affecting the effect of PNB were analyzed by univariate analysis and multiple ordered logistic regression method. R language was used to construct a nomogram model for predicting PNB effect, receiver operating characteristic (ROC) curve and calibration curve were drawn, and Hosmer-Lemeshow test was carried out to verify the prediction efficiency of the model. Results:The results of univariate analysis showed that 171 patients in the mild pain group had a median age of 71 (65, 75) years, a median PSA14.5 (9.6, 24.6) ng/ml, a median number of puncture needles of 20 (18, 22), and a median prostate volume of 34.94 (26.36, 45.12) ml, median BMI24.17(23.14, 25.79)kg/m 2, including 74 patients with a history of diabetes, 51 patients with a history of surgery, and 40 patients with a history of severe trauma; There were 110 patients in the moderate pain group, the median age was 71 (65, 76) years, the median PSA14.8 (11.03, 24.27) ng/ml, the median number of puncture needles was 23 (20, 24) needles, median prostatic volume 63.24 (49.14, 78.72) ml, median BMI23.91(22.58, 24.88)kg/m 2, including 26 patients with a history of diabetes, 29 patients with a history of surgery, and 10 patients with a history of severe trauma; In the severe pain group, 33 patients had a median age of 73 (67, 78) years, a median PSA14.6 (10.85, 34.80) ng/ml, and a median puncture needle number of 23 (22.5, 24) needles, median prostate volume 70.64 (61.50, 104.51) ml, median BMI24.32(23.00, 26.06)kg/m 2, including 9 patients with a history of diabetes, 10 patients with a history of surgery, and 7 patients with a history of severe trauma. The results of univariate analysis showed that the number of puncture needles ( P<0.01), prostate volume ( P<0.01), history of diabetes ( P=0.002) and history of major trauma ( P= 0.009) were the factors affecting the effect of PNB. Multiple logistic regression analysis showed that puncture needle number ( P=0.009), prostate volume ( P<0.01) and diabetes history ( P=0.041) were independent risk factors for PNB effect. The area under ROC curve (AUC) of the moderate and above pain prediction model was 0.872, P<0.01; the area under ROC curve of the severe pain prediction model was 0.817, P<0.01; the result of Hosmer-Lemeshow test of the moderate and above pain prediction model was χ2=5.001, P=0.757. The results of the severe pain prediction model were χ2=4.452 and P=0.814. The calibration curve was established, which showed that the prediction probability of pain degree was in good agreement with the actual risk. Conclusions:The number of puncture needles, prostate volume and history of diabetes are the risk factors affecting the effect of PNB. The prediction model of PNB effect based on this model can be used to predict the pain degree of patients undergoing prostate biopsy after PNB.

Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.
