We have successfully established two different laparoscopic procedures for early gastric cancer since March 1992, which are laparoscopic wedge resection of the stomach using a lesion-lifting method and laparoscopic intragastric mucosal resection. The indication is as follows; (A) mucosal cancer, (B) < 25 mm, if the lesion is elevated type, (C) < 15 mm and(More)
PURPOSE We report the performance of natural orifice transluminal endoscopic surgery (NOTES) low anterior resection in animals using transanal total mesorectal excision (TME) with laparoscopic assistance and endoscopic inferior mesenteric artery (IMA) dissection. METHODS Four pigs weighing 45 kg each, and one dog weighing 25 kg, underwent surgery via a(More)
Thirty patients with acute myocardial infarction admitted 2.1 +/- 1.1 (mean +/- standard deviation) hours after the onset of pain and with S-T segment elevation in multiple leads in the standard electrocardiogram were given either intravenous morphine (15 patients) or sublingual nitroglycerin (15 patients), and the effect on pain and QRS changes was(More)
The response of the premature fetus to speech stimuli was studied in 41 healthy pregnant patients at 26-34 weeks gestation. Speech stimuli consisted of repeated syllables ('ee' and 'ah') presented externally over the maternal abdomen at either 100, 105, or 110 decibels (dB). Sound stimuli were delivered during periods of both high and low fetal heart rate(More)
PURPOSE To quantitatively evaluate the rate of cup-to-disc ratio progression in treated patients with primary open-angle glaucoma and to identify clinical factors associated with cup progression. PATIENTS AND METHODS Fifty one eyes of 51 treated primary open-angle glaucoma patients with a minimum of 9-year longitudinal series of stereoscopic optic disc(More)
To provide insight into the maturation of neural mechanisms governing fetal heart rate and rate variability, seven chronically instrumented fetal baboons were monitored under steady state conditions between 120 and 165 days gestation (term 175 d). Forty records of 24 h duration (5-7 records/fetus) were evaluated. For each fetus, heart rate decreased with(More)
Patterns of fetal breathing activity were examined in a longitudinal study of the fetal baboon over the latter third of gestation. More than 1400 h of recorded tracheal fluid pressure in 16 or 24 h records from seven fetuses over a range in gestation from 121 to 172 days (term, 175-180 days) were analyzed. In these 81 records, there was a high degree of(More)
The relation between sequential changes in left ventricular contractility and atrioventricular (A-V) nodal conduction and refractoriness was assessed in open chest dogs during intravenous administration of acetylstrophanthidin (5 mug/kg) at 5 minute intervals until toxic arrhythmias developed. At each time interval, high fidelity left ventricular pressure,(More)
