Placement of PEG tubes through previously placed self-expanding esophageal metal stents.

BACKGROUND: Self-expanding metal stents are frequently used to palliate patients with malignant dysphagia and close tracheoesophageal fistulae. Despite proper stent positioning and deployment, in a subset of patients there is no improvement in dysphagia, closure of tracheoesophageal fistulae, or resolution of anorexia. Such patients may require a PEG tube. It has been suggested that PEG placement through a preexisting esophageal stent is problematic because of the risks of gastrostomy tube impaction within the stent and resultant stent migration. METHODS: Case records were retrospectively reviewed of 9 consecutive patients with indwelling esophageal self-expanding metal stents undergoing attempted PEG. OBSERVATIONS: PEG tube placement was successful in all patients. In 1 patient, the stent migrated distally into the stomach during PEG placement. This was managed endoscopically without further complication. CONCLUSIONS: PEG placement in patients with previously placed esophageal self-expanding metal stents is a relatively safe and feasible procedure, although stent migration may occur.

Massive rectal bleeding from colonic tuberculosis.

We describe a patient with massive rectal bleeding from colonic tuberculosis. This is an uncommon presentation of gastrointestinal tuberculosis with fewer than 20 cases reported in the medical literature. The incidence of tuberculosis has been increasing during the last decade. The resurgence of tuberculosis (secondary to increased immigration, more patients on immunosuppressive therapy, and the AIDS epidemic) mandates that the clinician be aware of the wide spectrum of presentation of intestinal tuberculosis. Endoscopy is the preferred method used to diagnose colonic tuberculosis.

Endoscopic removal of a toothpick from the transverse colon.

We describe the case of a patient who presented with abdominal pain, weight loss, and night sweats of 8 wk duration due to the impalement of a toothpick in the transverse colon. The toothpick, which was inadvertently swallowed, was successfully removed during colonoscopy. Therapeutic colonoscopy has replaced or lessened to a significant degree the need for traditional open surgical procedures to extract foreign bodies from the colon. Unexplained abdominal pain and constitutional symptoms should alert the clinician to the possibility of a foreign body.
