Digestive tract reconstruction is an important part of gastric carcinoma operation as well as tumor resection and lymph node dissection.Surgeons are seeking the optimal reconstruction method that reduces the occurrence of complications and maintains better quality of postoperative life extremely.Uncut Roux-en-Y anastomosis is a modified procedure in which an artificial jejunal occlusion is devised to avoid Roux stasis syndrome based on Billroth Ⅱ and Braun's anastomosis.Compared to the conventional Roux-en-Y anastomosis,the uncut Roux-en-Y anastomosis retains the advantage of preventing biliary and pancreatic secretions reflux,furthermore,it can decrease the symptoms associated with Roux stasis owing to the abnormal myoelectrical conduction of Roux limb.Because the early studies indicated that there was higher incidence of dehiscence or recanalization of the jejunal occlusion,the uncut Roux-en-Y anastomosis has not been widely applied.Since jejunal occlusion has been optimized recently,the uncut Roux-en-Y reconstruction may be an optional and appropriate method of digestive tract reconstruction after distal gastrectomy.

Objective To investigate the time and risk factors for spontaneous closure of patent ductus arteriosus (PDA) in preterm infants. Methods One hundred and seventy-seven preterm infants with arterial ductus unclosed were divided into three groups according to their gestational age as 28-31+6 weeks group (n=44),32-34+6 weeks group (n=59) and 35-36+6 weeks group (n=74).PDA was diagnosed by echocardiography in time of ≤12 h,-24 h,-48 h,-72 h,-96 h,-120 h,-144 h and >144 but ≤168 h after birth.The parameters of cardiac function included peak flow rate of aorta valve orifice,peak flow rate of pulmonary artery valve orifice,cardiac output,stroke volume,ejection fraction,the ratio of early (E) and late (A) diastolic velocities of mitral and tricuspid valves.The risk factors of arterial ductus spontaneous closure were determined by Logistic regression analysis.Results The cumulative spontaneous closure rates of preterm infants in three groups were 95.5%,100.0% and 100.0% within 168 h after birth respectively. There were significant differences of cumulative spontaneous closure rate in different time among three groups (x2 =4.23,7.45,12.46,7.14,4.75,6.47,3.89 and 3.89 respectively,P<0.05).After spontaneous closure of PDA during 12-24 h, peak flow rate of pulmonary artery valve orifice increased [(0.69±0.12) cm/s vs (0.65±0.12) cm/s,t=2.37,P=0.02],peak flow rate of aorta valve orifice [(0.65±0.11) cm/s vs (0.69±0.12) cm/s,t=2.51,P=0.02] and ejection fraction [(63.00±8.50) % vs (66.00±8.50) %,t=2.34,P=0.02] decreased.Logistic regression analysis showed that,the risk factors of preterm infants with arterial ductus unclosed within 24 hours after birth were gestation age (OR =1,825,95%CI:1.239-2.689),1 min Apgar score 0-3 (OR=1.946,95%CI:1.572-3.527) and early onset sepsis (OR=3.215,95%CI:1.245-5.463) ; gestation age (OR=3.270,95%CI:1.852-5.774),twins (OR=3.634,95%CI:1.489-8.871),1 min Apgar score 0-3 (OR=3.752,95%CI:2.156-5.436),Ⅲ-Ⅳ stage of respiratory distress syndrome (OR=2.897,95%CI:1.764-5.348) and early onset sepsis (OR=3.172,95%CI:2.134-6.437) were the risk factors of preterm infants with arterial ductus unclosed during 24-48 hours after birth; and gestational age (OR=2.471,95%CI:1.087-5.613),1 min Apgar score 0-3 (OR=2.985,95%CI: 1.469-5.736), Ⅲ-Ⅳ stage of respiratory distress syndrome (OR =3.645,95% CI:1.879-6.282),fluid volume excess (OR =4.135,95%CI:2.146-7.428) and early onset sepsis (OR=3.246,95%CI:2.146-4.526) for those with arterial ductus unclosed during 48-72 hours after birth. Conclusions The spontaneous closure rate of arterial ductus in the newborn infants whose gestational age over 28 weeks was above 90% in the first week after birth.There was no difference of left ventricular pump function between before and after the spontaneous closure.Reducing the incidence of premature birth,twins,severe asphyxia,severe respiratory distress syndrome, fluid excess and early onset sepsis might improve the spontaneous closure of arterial ductus.

Objective:To investigate the effects of dexmedetomidine combined with propofol on cognitive function, hemodynamics and diaphragm movement in elderly patients undergoing painless gastroenteroscopy.Methods:The clinical data of 82 patients who underwent painless gastroenteroscopy in Fuyang Minsheng Hospital from April 2021 to November 2022 were retrospectively collected, and they were divided into the control group and the observation group by anesthesia induction method, each group with 41 cases. The control group was anesthetized with propofol, and the observation group was anesthetized with dexmedetomidine and propofol. The recovery time, orientation recovery time and satisfaction of the two groups were compared; the cognitive function before anesthesia, 1, 12 h after anesthesia and 1, 7 d after anesthesia were compared; the changes of hemodynamics and diaphragm movement before anesthesia induction (T 0), 5 min after anesthesia induction (T 1) and at awakening (T 2) and adverse reactions were compared. Results:The recovery time, orientation recovery time in the observation group were shorter than those in the control group: (9.87 ± 1.52) min vs. (11.92 ± 1.74) min, (15.87 ± 2.31) min vs.(18.79 ± 2.54) min; the dosage of propofol was less than that in the control group: (200.21 ± 50.46) mg vs. (300.23 ± 60.29) mg; the satisfaction scores was higher than that in the control group: (9.54 ± 0.32) scores vs. (8.81 ± 0.47) scores, there were statistical differences ( P<0.05). The scores of Mini-Mental State Examination (MMSE) at 1 h after anesthesia and 12 h after anesthesia in the observation group were higher than those in the control group: (23.12 ± 1.86) scores vs. (20.31 ± 1.65) scores, (26.21 ± 1.43) scores vs. (24.12 ± 1.57) scores, there were statistical differences ( P<0.05). The scores of MMSE at 1, 7 d after anesthesia had no statistical differences between the two groups ( P>0.05). The levels of mean arterial pressure (MAP) and heart rate (HR) at T 1 and T 2 were decreased and the levels of MAP and HR at T 1 and T 2 in the observation group were higher than those in the control group: (76.48 ± 4.01) mmHg (1 mmHg = 0.133 kPa) vs. (72.31 ± 3.26) mmHg, (82.31 ± 3.27) mmHg vs. (77.97 ± 3.64) mmHg; (78.72 ± 2.17) bpm vs. (76.23 ± 2.35) bpm, (82.19 ± 3.08) bpm vs. (79.63 ± 2.56) bpm, there were statistical differences( P<0.05). The diaphragm thickness fraction (DTF) and diaphragmatic motion amplitude (DM) at T 1 and T 2 were decreased and the levels of DTF and DM at T 1 and T 2 in the observation group were higher than those in the control group: 0.21 ± 0.02 vs. 0.17 ± 0.03, 0.26 ± 0.03 vs. (0.22 ± 0.04); (15.67 ± 0.81) mm vs. (14.21 ± 0.77) mm, (16.72 ± 0.68) mm vs. (15.46 ± 0.82) mm, there were statistical differences ( P<0.05). The adverse reactions in the two groups had no significant difference ( P>0.05). Conclusions:The combination of dexmedetomidine and propofol has little effect on cognitive function, hemodynamics and diaphragm movement in elderly patients undergoing painless gastroenteroscopy, which can accelerate the recovery of patients and improve patient satisfaction.
