BACKGROUND The treatment of gastroparesis remains unsatisfactory despite prokinetic and anti-emetic drugs. Gastric electrical stimulation has been proposed as a therapeutic option. We have assessed the effect of gastric electrical stimulation on symptoms, medical treatment, body weight and gastric emptying in patients with intractable symptomatic(More)
The aim of the study was to evaluate the use of positron emission tomography with [18F]-fluorodeoxyglucose (FDG-PET) in patients with unexplained rising carcinoembryonic antigen (CEA) in the postoperative surveillance of colorectal cancer. 50 consecutive patients with elevated CEA levels and a completely normal (n=31) or equivocal (n=19) conventional(More)
This retrospective study was designed to assess the accuracy of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) in diagnosing recurrence of gastric cancer. Thirty-three patients who had received surgical treatment for gastric cancer with curative intent and who had subsequently undergone FDG-PET for suspected recurrence were retrieved(More)
To assess the clinical value of whole-body positron emission tomography (PET) with [18F]fluorodeoxyglucose (FDG) in recurrent colorectal cancer, 35 patients were studied: 15 had resectable liver metastases, one a resectable lung metastasis, eight resectable pelvic recurrence, eight a presacral mass with equivocal findings on imaging, and three increasing(More)
The clinical value of total body PET with FDG was evaluated in 76 patients presenting with or suspected of recurrent local or distant colorectal cancer. PET results were compared to those of routine imaging (CT pelvis, CT/US liver and CXR). The accuracy of PET for local disease was 95% which was superior to CT-pelvis (accuracy 65%). PET accuracy for liver(More)
To determine the procedure of choice for rectal cancer, particularly low rectal cancer. Complete search, according to evidence-based methods, of comparative studies and national surveys published in English since 1990. Selection criteria: comparative studies between abdominoperineal excision (APER) and sphincter-saving operations (SSO) with a minimum of 50(More)
A 67-year-old man presented with weight loss, intermittent severe abdominal pain and melaena. Initial radiology (including abdominal ultrasonography), gastroscopy and colonoscopy did not demonstrate any lesions that could explain the complaints. Three weeks later, upper gastrointestinal and small-bowel barium studies revealed two areas in the small(More)
BACKGROUND Proliferating cells in neoplasms usually show rapid cell cycle times and high rates of glycolysis. Tumor glucose utilization (TuGluc), potential cell doubling time (Tpot), and the effect of radiotherapy (RT) were evaluated in patients with primary rectal carcinoma. METHODS 2-[18F]-fluoro-2-deoxy-glucose (18F-FDG) was administered and dynamic(More)
AIMS In selected patients with colorectal liver metastases, hepatic resection offers an opportunity for cure, with a 25-38% 5-year survival rate. The aim of this prospective study was to evaluate whether patient selection could be improved with pre-operative whole-body 18-fluoro-2-deoxyglucose-positron emission tomography (FDG-PET) scan. METHODS(More)
Patients presenting diffuse, advanced, established peritonitis due to free perforation of the colon, in whom an adequate abdominal debridement cannot be obtained in one operative session were selected. We report results of the planned relaparotomy approach in 44 patients as compared with an historical series of 9 analogous patients treated by on demand(More)
