Background and study aims Dietary restrictions are integral to colonoscopy preparation and impact patient satisfaction. Utilizing split-dose, lower-volume polyethylene glycol 3350-electrolyte solution (PEG-ELS), this study compared colon preparation adequacy of a low-residue diet to clear liquids using a validated grading scale. Patients and methods This was a prospective, randomized, single-bl...

Endotracheal metastasis is a rare situation, usually associated with malignancies of breast and gastrointestinal tract, specially colon. Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to exte...

The current study describes the fibrinolytic treatment of a patient exhibiting an acute massive pulmonary thromboembolism, who was also receiving a bevacizumab-based combination regimen for metastatic colon cancer. The administration of bevacizumab has been associated with an increased risk of venous thromboembolic events and bleeding in cancer patients. However, there is insufficient data rega...

Measurement of transmural sodium fluxes across isolated, ouabain-inhibited turtle colon in the presence of a serosal-to-mucosal sodium gradient shows that in the absence of active transport the amiloride-sensitive cellular path contains at least two routes for the transmural movement of sodium and lithium, one a conductive path and the other a nonconductive, cation-exchange mechanism. The latte...

A 49 year old man with previous history of colectomy for colon cancer was referred to our department for further evaluation of suspicious hepatic lesions noticed during an abdominal CT scan. 99mTc-RBC scan revealed multiple hot spots in the region of the liver, correlating to the CT and liver-spleen scan. Further follow-ups of the patient revealed no remarkable change in the size or numbe...

Absorption of electrolytes and water from the human rectum was quantified by sequential sampling of physiological solutions instilled into the rectum and by the method of continuous intraluminal perfusion. The absorptive function of the rectum measured by the perfusion technique was also compared with that of the entire large intestine. The rectum did not absorb sodium, chloride, or water from ...

peutz–jeghers syndrome is a rare condition characterized by mucocutaneous pigmentation, polyposis and an increased cancer risk at a number of gastrointestinal and extra intestinal organs. we present a patient with a history of gastrointestinal bleeding with no mucocutaneous pigmentation. upper and lower gastrointestinal endoscopy revealed multiple polyps located in the deuodenum and colon. hist...
