Introduction
We compared laparoscopic Toupet fundoplication (LTF) and laparoscopic Nissen fundoplication (LNF) in neurologically normal children.Methods
Forty neurologically normal children who were followed up for more than 3 years after LTF (n = 22) or LNF (n = 18) were reviewed retrospectively. LTF and LNF were performed between 2006 and 2012.Results
There were no significant differences in gender (LTF, 15 male and 7 female patients; LNF:, 12 male and 6 female patients), mean age at surgery (LTF vs LNF: 2.5 vs 2.3 years), mean weight at surgery (LTF vs LNF: 9.6 vs 8.9 kg), preoperative symptoms, preoperative pH monitoring (pH <4) (LTF vs LNF: 26.7% vs 21.8%), mean operative time (LTF vs LNF: 117 vs 126 min), postoperative recommencement of enteral feeding (LTF vs LNF: 3.7 vs 3.8 days), or duration of hospitalization (LTF vs LNF: 5.5 vs 6.3 days). Intraoperative complications were esophageal trauma (LTF; n = 1; 4.5%) and liver trauma (LNF; n = 1; 5.6%) (P = 0.70). Post‐LTF complications were wrap stenosis (n = 1; 4.5%), and post‐LNF complications were wrap stenosis (n = 1; 5.5%) and gastric outlet obstruction (n = 1; 5.5%) (P = 0.43); all were managed conservatively. No case required conversion to open repair. There was no recurrence after LTF, but there were three cases (16.7%) after LNF (P = 0.08). Reoperation was performed at 4, 11, and 13 months, respectively.Conclusion
Despite LTF and LNF appearing to be equally effective, three LNF cases required reoperation. 相似文献2.

We describe herein a case of unilateral pulmonary agenesis (PA) with oesophageal atresia (EA)/tracheoesophageal fistula (TEF) that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up. 相似文献

Purpose
The potential benefits of thoracoscopic repair (TR) of esophageal atresia and tracheoesophageal fistula (EA/TEF) in newborns are still unclear. Our aim was to define the criteria, perioperative outcome after undergoing TR versus open repair (OR) for EA/TEF.Patients and methods
A retrospective chart review was conducted of 36 consecutive neonates who underwent EA/TEF repair between 2001 and 2012 in Shizuoka Children’s Hospital. Patients in this study were birth weight >2,000 g, and did not have severe cardiac malformations or chromosomal aberrations. Of the 26 newborns who met the selection criteria, 11 patients underwent attempts at TR compared to 15 patients who underwent OR. All cases were followed 1 year after operation at least.Results
All 11 TR were successfully completed. There were no significant differences between intra- and perioperative complications in the two groups. Intraoperative EtCO2 and arterial blood gases were not significantly different between the two groups. We did not found eating disorder, respiratory disorder, and failure of growth in all cases.Conclusion
In our study, the thoracoscopic approach appeared to be favorable and safe for EA/TEF repair in carefully selected patients. 相似文献5.
The binding of 125I-labeled human luteinizing hormone (hLH) to the 2000-g fraction of human ovarian follicles and corpora lutea during the entire menstrual cycle was examined. Specific high affinity, low capacity receptors for hLH were demonstrated in the 2000-g fraction of both follicles and corpora lutea. Specific binding of 125I-labeled hLH to follicular tissue increased from the early follicular phase to the ovulatory phase. Specific binding of 125I-labeled hLH to luteal tissue increased from the early luteal phase to the midluteal phase and decreased towards the late luteal phase. The results of the present study indicate that the increase and decrease in receptors for hLH during the menstrual cycle might play an important role in the regulation of the ovarian cycle. 相似文献

Menstrual cycle-dependent expressions of activin A in normal human endometrial tissues have been reported. Expression of activin receptor mRNAs and increased activin A production were also observed in human endometrial adenocarcinoma tissues, suggesting that activin A might enhance cell proliferation and inhibit apoptotic signaling in endometrial cancer cells. In this study, we have examined the effects of activin A on cell proliferation, anticancer drug-induced apoptosis and Fas-mediated apoptosis in 3 differentiated human endometrial adenocarcinoma cell lines, namely HEC-1, HHUA and Ishikawa. Flow cytometric analyses revealed moderate expressions of all 4 types of activin receptor subunits on the cell surfaces of the 3 cell lines. The proliferations of the 3 endometrial cancer cells were completely unaffected by activin A, whereas it suppressed the cell proliferation of a human ovarian endometrioid adenocarcinoma cell line, OVK-18, in a dose-dependent manner. Moreover, activin A did not affect the apoptotic changes in the 3 endometrial adenocarcinoma cells treated with 4 different anticancer drugs, namely CDDP, paclitaxel, etoposide and SN38. The apoptotic changes in HHUA cells treated with anti-Fas IgM were also unaffected by activin A. These results indicate that the increased activin A production in human endometrial adenocarcinoma tissues in vivo may not stimulate carcinoma cell proliferation or inhibit apoptotic signaling in carcinoma cells. Insensitivity to the usual growth suppression signals induced by activin A might be one of the mechanisms of immortality of human endometrial adenocarcinoma cells. 相似文献

The precise role of vasopressin in the pathophysiology of cardiovascular disease is controversial, but this peptide hormone is important for several reasons. Firstly, circulating concentrations of vasopressin are elevated in heart failure and some forms of hypertension. Secondly, there is evidence that vasopressin is synthesized not only in the hypophysial-pituitary axis but also in peripheral tissues including the heart where it acts as a paracrine hormone. Thirdly, vasopressin has vasoconstrictor, mitogenic, hyperplastic and renal fluid retaining properties which, by analogy with angiotensin II, may have deleterious effects when present in chronic excess. Finally, the availability of orally active non-peptide vasopressin receptor antagonists allows vasopressin receptor antagonism to be considered as a therapeutic option in cardiovascular disease. 相似文献

Experiments were performed to explore the effect of microwave tissue coagulator (MTC) on post-lobectomy regeneration of the liver and the regeneration-promoting effect of fructose-1,6-diphosphate (FDP) on heat injury of the liver after 40% hepatectomy in rats. Concerning the effect of MTC on hepatic regeneration, a MTC group showed a significantly higher serum LDH level on post-operative day 2, compared with a simple ligation group. A significant difference in DNA synthesizing activity between two groups was noted only in the peripheral region of regenerating liver tissue. A marked depression was observed on post-operative day 2 in the MTC group, 433 +/- 50 dpm/micrograms DNA as compared to 782 +/- 111 dpm/micrograms DNA in the simple ligation group, and also in respect of protein synthesis and labeling index. Administration of FDP prior to operation brought about a complete inhibition of the serum LDH elevation. DNA synthesis was significantly enhanced in the peripheral region of regenerating liver tissue in rats pretreated with FDP (422 +/- 52, 783 +/- 112 and 912 +/- 115 dpm/micrograms DNA in the saline, FDP 0.25 mmol/kg and FDP 0.8 mmol/kg groups, respectively). Similar trends were observed as to protein synthesis and labeling index. FDP has been proven to be effective on protection of the liver cells as well as on promotion of the liver regeneration following hepatic resection by MTC. 相似文献
