The development of Laparoscopic Linear Endostaplers (LLES) is crucial in minimally invasive approaches in bariatric surgery, but there have been very few published studies comparing 6-row LLES in Laparoscopic Sleeve Gastrectomy (LSG). The objective of this study was to compare two 6-row LLES in LSG.
Methods
A total of 60 patients were prospectively randomized to undergo LSG with either Medtronic Endo GIA? Tri-Staple technology (MTS) or AEON ? Endostapler(Lexington Medical) LLES. The measured parameters included patient demographics, comorbidity indices, LLES and specimen characteristics, postoperative symptoms, hospital stay, and total adverse events (AEs). Intraoperative bleeding was evaluated using five laparoscopic and corresponding endoscopic images of staple line before clip application, compared with a 1–5 Visual Analogue Scale (VAS), assessed by an independent bariatric surgeon who was blinded to the LLES used. Images of all cases were reviewed on the same day to increase test–retest reliability.
Results
Both groups were similar in patient demographics. Compared to MTS, AEON LLES group had significantly lower bleeding VAS scores in 4/5 laparoscopic images (pre-pyloric: 1.7?±?0.7 vs. 2.36?±?0.76, p?=?0.0007, mid-sleeve: 1.46?±?0.62 vs. 1.86?±?0.68, p?=?0.019, proximal sleeve: 1.6?±?0.77 vs. 2.0?±?0.83, p?=?0.038, gastro-esophageal junction: 1.43?±?0.67 vs. 1.86?±?0.77, p?=?0.014) and 3/5 endoscopic images (pre-pyloric: 1.56?±?0.56 vs. 2.36?±?0.76, p?=?0.006, incisura: 1.66?±?0.54 vs. 2.0?±?0.52, p?=?0.021, mid-sleeve: 1.63?±?0.49 vs. 2.0?±?0.45, p?=?0.005). There was no statistical difference in other parameters.
Conclusion
Both devices were equally safe and effective in terms of LLES and specimen characteristics, patient symptoms, hospital stay, and AEs. Bleeding VAS scores were significantly lower, favoring the AEON LLES.
OBJECTIVE: The aim of the study was to describe the occurrence of spontaneous version in twins in the third trimester, as well as the correlation between antepartum and birth presentation. METHODS: Twin pregnancies were divided into four gestational age intervals: 20-23; 24-27; 28-31; and 32-36 weeks. Fetal presentation was categorized as cephalic (C) or non-cephalic (NC). Hospital records were reviewed to determine demographic factors, including mode of conception. Chi-square was used to compare distributions of presentations, and Cramer's V measure of association was used to correlate presentations in individual pregnancies between antepartum intervals and birth. RESULTS: A total of 207 pregnancies were included. The distribution of fetal presentations changed significantly through gestational age intervals (p < 0.001), although they were similar between 32-36 weeks and birth (p = 0.75). Correlation between antepartum and birth presentation in individual pregnancies strengthened throughout the four intervals. No correlation was seen between parity, gender, birthweight, or in vitro fertilization and fetal presentation or rate of spontaneous version.CONCLUSION: Many twins undergo spontaneous version in the third trimester, though there is excellent correlation between presentation at 32-36 weeks and birth. A cephalic presenting twin at > or = 28 weeks is highly likely to be in cephalic presentation at delivery. 相似文献
One hundred and fifty patients presenting with small cell lung cancer (SCLC) to chest physicians, were assessed neurologically. Neuromuscular or autonomic deficits were common and occurred in up to 44% of cases. Weakness, dry mouth, and weight loss were not mutually independent and may represent the syndrome formerly described as carcinomatous neuromyopathy. By contrast, undoubted paraneoplastic syndromes were much less commonly detected. Two patients had the Lambert-Eaton myasthenic syndrome (LEMS) and one had subacute sensory neuropathy (SSN). In these patients, neurological symptoms antedated other manifestations of cancer, by between six and 17 months. The 95% confidence interval for the prevalence of LEMS or SSN among SCLC patients was 0-4%, consistent with the results of previous retrospective or smaller studies: summing these, the overall prevalence of LEMS among SCLC patients is close to 3%, which implies about 250 new cases per annum in England and Wales. If LEMS and SSN are the least uncommon neurological paraneoplastic syndromes in SCLC patients, this may reflect the accessibility of motor nerve terminals and dorsal root ganglia to cross-reactive anti-tumour cell antibodies. 相似文献
Our experience with 184 previously untreated patients who had adenoid cystic carcinoma of salivary gland origin is reviewed. Retrospective staging was possible in all but nine patients who had minor salivary gland primary tumors. Sixty-three percent of patients were diagnosed as having stage I or stage II disease (stage I, 64 patients; stage II, 47 patients), whereas 43 and 21 patients had stage III and IV tumors, respectively. Grading was as follows: cribriform pattern only (grade 1, 126 patients; 68%), mixed cribriform and solid features (grade 2, 48 patients; 26%), and solid only (grade 3, 10 patients; 5%). Treatment was predominantly surgical (174 patients), and relatively few patients received adjunctive, postoperative irradiation (27 patients). Cumulative 10-year survival was 75%, 43%, and 15% for stage I, stage II, and stage III and IV patients, respectively, and cause-specific survival at 10 years was as high as 94% in patients with stage I disease. Only the clinical stage had a significant impact on survival. Neither survival, regional metastases (16 patients; 11%), nor distant dissemination (64 patients; 43%) was predictable on the basis of tumor grade alone. The prognosis in patients with early stage lesions may be better than has been appreciated. 相似文献
