Duodenogastric reflux may have pathophysiologic importance, but its mechanism is poorly understood. We propose that duodenogastric reflux and periodic changes in motor and secretory activity of the upper gut during fasting may be related. Therefore we determined the relationships between duodenogastric reflux and interdigestive motor-secretory cycles in a(More)
The etiologies of combined fecal and urinary incontinence may be interrelated but remain poorly understood. A potential variable in this process is global pelvic floor dysfunction. The aim of this study was to prospectively assess the use of phased-array, body coil dynamic MRI in identifying pelvic floor abnormalities in patients with combined incontinence(More)
Of 29 consecutive patients with acute bleeding from esophageal varices, 27 were treated by injection sclerotherapy. Bleeding was controlled by injection in 25 patients. Long term injection therapy was undertaken in these 25 patients. Obliteration of the varices was achieved in five, two of whom had re-canalization and rebleeding. Patent varices remained in(More)
OBJECTIVE The aim of this study was to develop a technique to simultaneously evaluate bladder and anorectal function. In particular, this study was designed to determine if anal sphincter resting pressure, anal sphincter squeeze pressure and rectal sensation change with bladder filling. PATIENT AND METHODS A pilot study of ten female patients who(More)
Extracorporeal shock wave lithotripsy (ESWL) is successful in fragmenting gallstones, but less than 28 per cent of patients with gallstone disease fulfil the conventional criteria for treatment. However, no data exist to substantiate these selection criteria. In this study, the selection criteria were broadened to include patients with radiolucent stones of(More)
OBJECTIVE International randomized trials have endorsed the routine use of laparoscopic techniques in colorectal surgery. The authors hypothesize that the overall care pathway in minimal access resection was cheaper than conventional open resection. METHOD This was a case-matched study of consecutive patients undergoing laparoscopic resection between July(More)
Coumarin (1,2-benzopyrone) as a daily oral dose of 50 mg was evaluated in a multicentre prospectively randomized, double-blind, placebo-controlled trial to prevent early recurrence of malignant melanoma TNM Stage IB (Breslow thickness greater than 1.70 mm) and Stage II. Intake for the trial started in 1984 and was stopped prematurely, after review, in 1987.(More)
The objective of the study was to determine whether the metrics from a left-sided laparoscopic colectomy (LC) simulator could distinguish between the objectively scored performance of minimally invasive colorectal expert and novice surgeons. We report our results from the first virtual reality-based laparoscopic colorectal training course for experienced(More)
PURPOSE The trend toward avoidance of a colostomy at both elective and emergency large-bowel surgery is partly driven by the perceived morbidity and low closure rates of temporary stomas. The aim of this study was to examine whether significant colostomy-related morbidity remains persistently high. METHODS To examine this, we reviewed 120 patients with a(More)
