Strips from opossum lower esophageal sphincter were prepared and mounted in organ baths for recording of isometric tension. Nonadrenergic, non-cholinergic (NANC) inhibitory responses were evoked by transmural field stimulation. The relaxant responses to field stimulation were inhibited in a concentration-dependent manner by N omega-nitro-L-arginine (L-NNA),(More)
PURPOSE An extended Hartmann's procedure is occasionally useful in rectal resections, because anastomotic, perineal, and functional problems are eliminated. This study was designed to examine the occurrence of pelvic sepsis after this procedure and identify possible risk factors. METHODS Medical records were available for 163 patients (89 females)(More)
BACKGROUND The use of biological therapy (biologicals) is established in the treatment of Crohn's disease. This study aimed to determine whether preoperative treatment with biologicals is associated with an increased rate of complications following surgery for Crohn's disease with intestinal anastomosis. METHODS All patients receiving biologicals and(More)
We present a case of amoebic colitis, misdiagnosed as inflammatory bowel disease and treated with corticosteroids, leading to severe necrotizing enterocolitis. We review the literature on the epidemiology, pathogenesis, diagnosis, and treatment of amoebic dysentery, with special emphasis on the association between immunosuppressive treatment and the(More)
A specially designed probe was used to investigate biomechanical wall properties of the esophagus in opossums with distal esophageal banding. A balloon was stepwise inflated and deflated 6 cm above the lower esophageal sphincter before the banding and at 2 weeks postoperatively. After animals were killed, collagen content of the esophageal wall was(More)
A fistula is defined as a pathological connection between the intestine and an inner (bladder or other intestine) or outer (vagina or skin) epithelial surface. Fistulas are discovered in up to 25% of all Crohn's disease patients during long-term follow-up examinations. Most are perianal fistulas, and these may be classified as simple or complex. The initial(More)
We present a case of secondary achalasia due to an adenocarcinoma of the stomach with no tumor infiltration of the esophagus. Immunohistochemical staining revealed a massive infiltration of activated eosinophils in the muscularis of the esophagus with secretion of the highly cytotoxic and neurotoxic eosinophil cationic protein (ECP). Immunohistochemical(More)
1. The role of the L-arginine-nitric oxide (NO) pathway for non-adrenergic, non-cholinergic (NANC) relaxation of the guinea-pig taenia coli was studied by recording isometric tension in response to transmural field stimulation (TMS). 2. In preparations precontracted with prostaglandin F2 alpha (PGF2 alpha, 10(-6) M), TMS induced frequency-dependent(More)
Smooth muscle specimens were taken from the oesophagogastric junction (OGJ) in patients operated on for gastrointestinal malignancies not involving the OGJ. The smooth muscle bundles of the inner, circular layer of the OGJ were richly innervated by fine nerve fibres staining positively for NADPH diaphorase. The outer longitudinal layer had a markedly lower(More)
Smooth-muscle specimens from the lower esophagus of nine patients operated on for esophageal achalasia were examined with routine hematoxylin-eosin staining. This procedure revealed only a few eosinophils in or between the external smooth-muscle layers. Using specific immunohistochemical methods for the detection of the eosinophil cationic protein (ECP),(More)
