Objective To study the effect of octreotide on patients with postoperative acute adhesive small bowel obstruction. Method In this study, 87 patients with postoperative acute adhesive small bowel obstruction were divided into 2 groups: experimental group (46 patients) and control group (41 patients). Patients in the control group were treated with routine therapy, including gastrointestinal decompression, intravenous infusion, antibiotic and enema. Patients in the experimental group were treated with routine therapy plus somatostatin analogue (octreotide) 0.1 mg. ih q8 h. for 72 hour. The alleviation of abdominal symptom and sign and the possibility of surgical intervention are observed and compared.Results Compared to the control group, the obstruction in the experimental group alleviated significantly,the abdominal pain relieved, the amount of draining decreased, and the passage of gas was earlier.Conclusions Based on the routine therapy, the use of octreotide significantly relieves the symptoms of obstruction and shortens the course of conservative therapy.

Objective To understand the effect of standardized training for resident doctors and to improve its evaluation method. Methods A questionnaire survey was made among 89 resident doctors including 46 directors and 46 matrons. Kirkpatrick Model was used to analyze the question-naires in four dimensions including reaction layer,learning layer,behavior layer and achievement layer. Data of reaction layer were analyzed by ANOVA and data of learning layer and behavior layer were compared by paired t-test. Results Reaction layer:the overall satisfaction of the resident doc-tor for training is about 4.09. Learning layer:There were significantly statistical differences in the test scores before and after training(P=0.00). Behavior layer:There were significantly statistical differences in resident doctor’s ability and quality before and after training (P=0.00). Achievement layer:both the complaint rate and the accident rate of the 89 resident doctors were 0 while all of them passed the practicing physician exam. Conclusions Standardized training can improve the quality and ability of resident doctors. Kirkpatrick evaluation model can reflect the effect of the standardized training for resident and is a good tool to analyze the effectiveness of standardized training for resident.

Objective:To investigate the clinical efficacy of using INFIX combined with hollow nail in the treatment of anterior pelvic ring injury with symphyseolysis.Methods:Data of 12 patients with anterior pelvic ring injury and symphyseolysis who were treated from January 2016 to December 2018 were retrospectively analyzed. They were 8 males and 4 females with an average age of 39.5 years (range, 23-64 years). There were 4 cases of traffic injury, 3 cases of falling injury and 5 cases of crush injury; all the cases were combined with front and rear crush injury. According to Tile classification for pelvic fractures, there were 6 cases of type B1 , 3 cases of type B3, 1 case of type C1 and 2 cases of type C2. Six cases of B1 and 3 cases of B3 patients used percutaneous inter fixation with sacroiliac joint cannulated screw in posterior ring; 1 case of C1 and 2 cases of C2 used spinal-pelvic fixation. Every patients' operating time of INFIX combined with the pubic symphysis hollow nail , amount of hemorrhage, length of incisions and number of X-ray projections were recorded. Pelvic X-ray and CT scan were taken postoperatively to observe the reduction and screw position. Postoperative reduction quality was assessed using Matta radiological criteria and Majeed criteria was used at the final follow-up to evaluate the pelvic function.Results:The average operating time for 12 patients was 42 min (range, 35-56 min) ; the average amount of hemorrhage was 28 ml (range, 15-40 ml); the average length of incision at INFIX nail placement on both sides were 2.7 cm (range, 2.2-3.5 cm); the average length of incisions at the pubic symphysis hollow nail placement was 0.8 cm (range, 0.6-1.2 cm) and the average number of X-ray projections was 38 times (range, 26-55 times). Postoperative X-ray and CT scan showed that all the hollow screws are located accurately and firmly, and pubic symphysis had good reduction and no infection occurred in the surgical incision at the screw placement site. Postoperative reduction quality was evaluated according to Matta radiological criteria, and there were excellent in 10 and good in 2, giving an excellent to good rate of 100% (12/12). The average follow-up time for the 12 patients was 12 months (range, 6-15 months). At the final follow-up, all patients showed fine fracture union and no looseness of pubic symphysis occurred according to imaging test. According to the Majeed criteria, the pelvic function was excellent in 8 cases, good in 3 cases and fair in 1 case, giving a good to excellent rate of 91.7% (11/12). One case developed symptoms of femoral nerve compression after surgery and returned to normal after removal of the INFIX. Another case had damage to the lateral femoral cutaneous nerve and the symptoms disappeared after three months.Conclusion:Using INFIX combined with hollow nail in the treatment of symphyseolysis can lead to more minimally invasive with excellent postoperative efficacy and markedly reduced the morbidity of complication.

Objective:To investigate the clinical effect of using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring.Methods:Data of 7 patients with old vertical unstable fracture dislocation of posterior pelvic ring admitted and followed up from January 2017 to April 2020 were retrospectively analyzed, including 4 males and 3 females with an average age of 42.4 years old (range, 22-73 years old). There were 3 cases of traffic injury, 3 cases of falling injury and 1 case of tumble injury. According to Tile classification for pelvic fractures, there were 5 cases of type C1, 1 case of type C2 and 1 case of type C3. The average time from fracture to surgery was 5.4 weeks (range, 3-10 weeks). Among the 7 patients, 4 patients' posterior ring fractures were fixed by combined lumbar pelvic triangle fixation, and 3 patients' posterior ring fracture were fixed by combined lumbar pelvic fixation. 4 patients' anterior ring injury were not treated, 2 patients' anterior ring injury were treated by closed cannulated screw and internal fixation, and 1 patient's anterior ring injury was fixed by INFIX and cannulated screw. Every patient's operating time, intraoperative blood loss, length of incision and times of X-ray fluoroscopy were recorded. Pelvic X-ray and CT scan were taken postoperatively to observe the condition of reduction and screw position. Postoperative fracture reduction quality was assessed by Matta radiological criteria and Majeed criteria was used at the final follow-ups to evaluate the degree of functional recovery after pelvic fracture.Results:The average operating time of 7 patients was 143 min (range, 96-205 min); the intraoperative average blood loss was 579 ml (range, 300-1 650 ml); the average length of incisions was 12.9 cm (range, 9-15 cm) and the average time of X-ray fluoroscopy was 27 times (range, 15-52 times). Postoperative X-ray and CT scan showed that the displacements of the posterior rings were reset well and all the hollow screws were located accurately and firmly. Postoperative radiation quality was evaluated according to Matta radiological criteria, and there were 4 cases of excellent, 2 cases of good and 1 case of fair, with an excellent and good rate of 85.7% (6/7). Seven patients had good fracture union. The average followed up time for all 7 patients was 12 months (range, 6-16 months). At the last follow-up, imaging examination showed good reduction of the sacroiliac joint, and the reduction of anterior and posterior rings were not lost. The healing time was 14.2 weeks (range, 12-20 weeks). Majeed score: postoperative 4.90±6.64 points (range, 48-58 points), postoperative 3 months 71.40±7.32 points (range, 67-75 points), postoperative 6 months 84.90±8.14 points (range, 68-96 points), the difference was statistically significant ( F=0.614, P=0.004). Majeed score 6 months after operation showed that 5 cases were excellent, 1 case was good and 1 case was fair, and the excellent and good rate was 85.7% (6/7). Conclusion:Using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring has good reduction quality, high fixed strength and good postoperative effect.
