Objective To analyze the clinical features of adult patients with acute intestinal obstruction secondary to Meckel's diverticulum and the experience in management of the disease.Methods The clinical data and pathological features of 9 patients with acute intestinal obstruction secondary to Meckel' s diverticulum were retrospectively analyzed. Results All patients were diagnosed with acute intestinal obstruction secondary to Meckel's diverticulum via abdominal cavity exploration and underwent surgical treatment. Before surgical treatment, 1 out of 9 patients was correctly diagnosed as acute intestinal obstruction secondary to Meckel's diverticulum, and the other 8patients were diagnosed as acute intestinal obstruction. Diverticulum was resected in 5 cases and the rest 4 cases received partial excision of small intestine including the diverticulum. Pathological examination showed that all patients had inflammatory changes in diverticulum. Some patients were complicated with mucosal erosion, small ulcers, bleeding or perforation. Forty-four percent (4/9) of diverticula contained ectopic tissue. All patients were cured. Conclusion Meckel's diverticulum is a rare cause of acute intestinal obstruction and preoperative diagnosis is difficult. Diverticulum,howere,is likelihood to develop strangulation or contains ectopic tissue, so that the surgical treatment should be performed early.

Objective To study the impact of individualized birth process management on birth outcomes of low-risk parturient unipara .Methods 729 parturient women were divided into the experimental group ( n=503 ) and the control group ( n=226 ) .The free position during labor was used in the control group . In the experimental group , individualized labor movements and pre-delivery positions were provided to improve the birth outcome .The incidence of emergency cesarean section and use of obstetric forceps were compared between groups .Results A total of 468 parturient women in the experimental group were in spontaneous labor , with an incidence of 93.04%;198 parturient women in the control group were in spontaneous labor , with an incidence of 87.6%.The use of obstetric forceps in the experimental group was 1.59%, which was lower than 3.98%in the control group .Twenty-six parturient women in the experimental group went through emergency cesarean section , with an incidence of 5.17%; nineteen parturient women in the control group went through emergency cesarean section , with an incidence of 8.41%.The difference was significant between groups (χ2 =6.97 ,P<0.05 ) .The most frequent labor position in the experimental group was semireclining position , with an incidence of 90.46%.The least use labor position was kneeling-squatting position , with an incidence of 4.57%.Conclusions The Individualized birth process management can significantly decrease the rate of emergent cesarean and forceps delivery .
