Objective: To determine which demographic factors may influence serum gastrin and pepsinogen I (PGI) levels in duodenal ulcer patients
undergoing omeprazole treatment.
Methods: We conducted an outpatient-based prospective study in the Veterans General Hospital, Taipei, to investigate the pharmacological
effects on patients with duodenal ulcers receiving omeprazole treatment for 4 weeks. Sixty-eight patients (61 males/7 females,
aged 25–73 years) with endoscopically confirmed duodenal ulcer were included. Gastrin and pepsinogen I levels were measured
before and after treatment. Demographic factors including age, sex, smoking, ulcer healing and antral Helicobacter pylori colonization/clearance were analyzed, in order to measure their probable influences on serum gastrin and pepsinogen I levels.
Results: Ulcer healing was seen in 92.6% of patients while 48 (70.6%) antral clearances were seen in 66 H. pylori colonized patients at the end of trial. Omeprazole monotherapy led to a marked elevation of serum gastrin (85.8 pg · ml−1, SD 32.0 pg · ml−1 vs 133.9 pg · ml−1, SD 71.6 pg · ml−1, P < 0.01), and pepsinogen I (111.0 ng · ml−1, SD 36.7 ng · ml−1 vs 253.6 ng · ml−1, SD 64.8 ng · ml−1, P < 0.01) levels when measured on day 29. Only patients showing antral H. pylori clearance exhibited an influence on the magnitude of pepsinogen I elevation following omeprazole monotherapy (143.9%, SD
67.3% vs 78.6%, SD 51.2%, P < 0.01). Moreover, the sensitivity and specificity of serum pepsinogen I variations were plotted on a receiving operating
characteristic (ROC) curve. The 140% increased pepsinogen I level yielded a maximum accuracy of 80% specificity or 50% sensitivity
to predict antral H. pylori clearance.
Conclusion: Antral H. pylori clearance is at least partially responsible for the omeprzaole-induced hyperpepsinogenemia I. The magnitude of hyperpepsinogenemia
I probably provides a non-invasive alternative for predicting H. pylori clearance.

Zusammenfassung Es wird über die Langzeitergebnisse von 216 Patienten berichtet, bei denen zwischen 1970 und 1978 wegen eines Ulcus duodeni eine selektiv proximale Vagotomie (SPV) vorgenommen wurde. Die mittlere Nachbeobachtungszeit beträgt 12,8 Jahre (8,3–15). 26 Patienten erlitten ein symptomatisches Ulkusrezidiv (12%)4–135 Monate postoperativ, die kumulative Rezidivrate beträgt 20,3 % nach 13 Jahren (Kaplan-Meier). Säuresekretionsmessungen ergaben eine mittlere Reduktion der basalen (BAO) und mittleren stimulierten Sekretionswerte (MAO) von 80,7 bzw. 74,8 % ohne Unterschiede zwischen Patienten mit und ohne Rezidiv. Das Rezidivrisiko war für Ulcus duodeni (22 von 194) und pylorische Geschwüre (4 von 22) vergleichbar, ebenso fanden sich keine Unterschiede bezüglich dem Geschlecht, einer zusätzlichen Drainage-Operation, dem Rauchverhalten, akuter oder elektiver Operation und erstem oder Rezidivgeschwür. Nach der Operation komplizierter Ulzera war das Rezidivrisiko tendentiell höher (p 0,07). 78,5% der Patienten erreichten ein (sehr) gutes funktionelles Langzeitergebnis (Visick I oder II), nur 6% mußten als Visick III eingestuft werden. Die SPV kann daher als ein ungeachtet der Patienten-Compliance wirksames und wertvolles Therapieverfahren zur Behandlung des Ulcus duodeni erachtet werden.
Results of highly selective vagotomy after 13 years
Summary This study reports the long-term results of 216 patients after highly selective vagotomy (HSV) for duodenal ulcers operated from 1970 through 1978 with a mean follow-up of 12.8 years (8.3–15). 26 patients developed symptomatic ulcer recurrences (12%) within 4 to 135 months following surgery, the cumulative recurrence rate (Kaplan-Meier) at 13 years was 20.3%. Acidity analyses showed a postoperative mean reduction of basal acid output (BAO) and maximal acid output (MAO) values of 80.7 % and 74.8 % respectively with no differences according to recurrences. The risk of recurrence was similar for duodenal (22/194) and pyloric ulcers (4/22) and no differences were found with respect to sex, additional drainage procedure, smoking habits, acute or elective operation and first or recurrent ulcers. Risk was slightly higher for complicated ulcers (p 0.07), but without reaching statistical significance. 78.5% of patients showed (very) good results (Visick I or II), only 6% were Visick III. HSV is therefore regarded as a valuable therapeutic measure for the treatment of duodenal ulcer independent of patient compliance.相似文献

Effect of aging on bladder function and the response to outlet obstruction in female rats 总被引:3,自引:0,他引:3
Bladder dysfunction in the aging population is a significant problem. However the concomitant presence of other diseases
in many patients can make it difficult to distinguish between changes in bladder function and other influences. The present
study was designed to study, in aging rats, bladder function and the effect of partial bladder outlet obstruction (BOO) on
bladder function. Cystometrics were performed in awake, female Fischer 344 rats of four age groups (6, 12, 18 and 24 months)
following subcutaneous implantation of a mediport catheter. Cystometric evaluations were carried out in control rats or those
subject to three weeks of BOO. Bladder compliance significantly decreased with aging, which reflected an increase in threshold
pressure without changes in bladder capacity. Partial BOO caused development of severe bladder instability. Following BOO,
bladder capacity and compliance were significantly increased in all age groups. Threshold pressure was lower in obstructed
animals, except for 6-month rats. Younger animals were able to generate a higher contraction pressure to compensate for the
BOO, whereas older animals did not. Using an awake model of cystometric measurement, we have demonstrated that aging, by itself
can affect bladder function. Furthermore, aged animals respond differently to BOO than younger animals. These results demonstrate
that both aging and disease can contribute to bladder dysfunction, and suggest that treatment of bladder dysfunction may require
a combination of therapies targeted to multiple etiologies.

Does gut atresia cause polyhydramnios? 总被引:1,自引:0,他引:1
Fetal gut atresia is variably associated with polyhydramnios. In order to determine which pregnancies will develop polyhydramnios,
the case notes of 80 babies with gut atresia and stenosis were reviewed. Maternal polyhydramnios developed in all cases of
pure oesophageal atresia (n=8), all cases of Type III duodenal atresia (DA) with a non-bifid bile duct (n=8), 80% of cases with type I DA (n=10), and 24% of atresias of the small intestine (n=34). Polyhydramnios did not develop in any case where there was not total obstruction except in 1 baby with DA and a bifid
bile duct (BBD). These included stenosis of the oesophagus and duodenum (n=17) and DA type III with a BBD (n=3). These results support the role of fetal swallowing and fluid absorption by the fetal gastro-intestinal tract in the regulation
of amniotic fluid volume.

胃癌患者血清和组织一氧化氮水平变化及临床意义 总被引:21,自引:0,他引:21
应用比色法测定了34例胃癌患者血清和组织粘膜的一氧化氮(NO)含量,并设30例正常人及30例球部溃疡为血清对照组。23例组织对照组系取自癌旁组织(肉眼和病理均属正常)。结果显示胃癌患者血清一氧化氮水平明显低于正常对照组及十二指肠球溃疡组(P<0.01);而十二指肠球溃疡组则明显高于正常对组(P<0.01),胃癌组织中NO含量则显著高于癌旁组织(P<0.01)。研究表明当肿瘤发生时,经诱导活化的巨噬细胞可以产生大量的NO於病灶组织中而发挥其免疫功能,即NO直接作用于肿瘤细胞,启动机体其他免疫防御系统而杀伤肿瘤细胞并在粘膜损伤时有重要的修复功能。故而表现出血中NO水平下降,而胃癌组织局部NO水平升高。 相似文献

Objective To evaluate the feasibility and indication of laparoscopie duodenoduoden-ostorny for neonates with congenital duodenal obstruction- Methods From May 2004 to Feburary 2008,6 newborns with duodenal obstruction underwent exploratory laparoscopy. With a lower-pressure pneumoperitoneum of 5~8 mmHg and a suspending suture for right liver elevator, the procedure was performed using 3 cannulas of 3.3 mm to 5.5 mm diameter. Under the laparoscopic vision, the cause of duodenal obstruction was diagnosed and a sutured anastomosis was performed after the duodenum mo-bilized. Results Findings at laparoscopy included duodenal diaphragm in 3 cases,annular pancreas in 2 cases, and preduodenal portal vein in 1 case. Three cases with duodenal diaphragmatic stenosis were en-countered a partial excision of the diaphragm after vertical incision of the anterior part of duodenum followed laparoscopically by a transverse suture. A diamond-shaped side-to-side duodenoduodenal anas-tomosis was successfully carried out in 2 cases of annular pancreas through a laparoseopic approach, but a duodenojejunostomy was converted to mini-laparotomy during the laparoscopic course of a predu-odenal portal vein. The average operative time was 102 16.5 min (85~135 min). Visualization was ex-cellent, and there were no intraoperative complications. Feedings were started on postoperative day 3 to 5. All cases were on full feedings after 8 to 10 days. Follow-up upper gastrointestinal tests showed no evidence of stricture or obstruction. Conclusions The duodenoduodenostomy with laparoseopy can be performed in neonates securely and appropriated for a full-term newborn with tolerance CO2 pneumo-peritoneum. It provides an excellent and micro-invasive way to evaluate and treat congenital duodenal obstruction. 相似文献
