Jejunal GIST — An Obscure Cause of Melaena

Gastrointestinal Stromal Tumours (GISTs) are one of the rare causes of Alimentary Tract Neoplasm. They arise from the Interstitial Cells of Cajal (ICC) with overexpression of proto-oncogenes like KIT, PDGFRA and BRAF-Kinase, etc1. The typical location of these tumors is the stomach with Jejunal GIST being the rarest variant. The maximal incidence of the disease is reported in the sixth decade of life. GISTs are often asymptomatic and clinicians are misdirected towards a different diagnosis because of its variable nature of presentation. The clinical feature typically ranges from non-specific abdominal symptoms like nausea, vomiting, bloating, etc, to abdominal emergencies like hemorrhage, anemia, or obstruction. Although mostly benign, there is a high probability of progression to malignancy2. Thus, in patients with no appreciable cause of gastrointestinal bleed or chronic abdominal discomfort, GIST should have high suspicion index. This can help to limit the progression and thereby prevent further complications. Due to its location, it is difficult to identify by Endoscopy or Colonoscopy. Single Balloon Enteroscopy (SBE) and CT Scan of Abdomen are the primary investigational modalities. The treatment aims at resection of the mass with continued Postsurgical surveillance and targeted molecular therapy in some cases. Herein, we report a 14-year-old boy with chronic paleness and gradual onset repeat episodes of Melaena. Despite repeated blood transfusions, the patient had a Hemoglobin

Outcome of Upper Gastro Intestinal Haemorrhage - a Hospital Based Prospective Study.

Upper GI bleeding is a common medical emergency with a significant mortality, outcome of which depends upon the cause, appropriate and early intervention in a specialized center. This study was carried out to see the outcome of patient with Upper GI haemorrhage. Fifty cases with episode of upper gastrointestinal haemorrhage, admitted into medicine units of Faridpur Medical College Hospital from January 2011 to December 2011, were studied. Duodenal ulcer was the commonest cause of haematemesis and melaena followed by oesophageal varices, gastric ulcer and erosive gastritis. The peak incidence was among 35 to 45 years of age. Over all male female ratio was 4.55:1 but in case of duodenal ulcer it was 9:1. During hospital stay recurrent bleeding was noted in 10% of patients and during subsequent follow up it was 10% of the total and 50% in case of variceal bleeding group. Over all hospital mortality was 4% .

Acute Lower Gastrointestinal Haemorrhage Secondary to Small Bowel Ascariasis

Acute lower gastrointestinal haemorrhage secondary to small bowel ascariasis is extremely rare. A high level of suspicion should be maintained when dealing with acute gastrointestinal haemorrhage in migrants and travellers. Small bowel examination is warranted when carefully repeated upper and lower endoscopies have failed to elicit the source of bleeding. Appropriate test selection is determined by the availability of local expertise. We present a case of acute lower gastrointestinal haemorrhage secondary to jejunal ascariasis and a literature search on lower gastrointestinal haemorrhage associated with jejunal infestation with Ascaris.

Anemia severa causada por Necator americanus: reporte de un caso / Severe anemia caused by Necator americanus: case report

En climas templados, yungas (zona intermedia entre valle y trópico) y trópico, prevalecen dos parásitos hematófagos: Necator americanusy Ancylostoma duodenale, responsable de una anemia crónica, que lleva a los niños a tener niveles tan bajos de Hb, que a veces sonconsiderados incompatibles con la vida; rara vez originan sangrado agudo severo.Describimos el caso de un niño, de seis meses de edad, procedente de Coroico (Nor Yungas) con disentería inicial, misma que luego secomplica con melenas y rectorragia de sangre rutilante que origina una hipovolemia severa, rayana en el choque. Sometido a exploraciónquirúrgica por persistencia del sangrado, previo gammagrafía para descartar un divertículo de Meckel, no se halla el sitio de sangradopor lo que se realiza laparotomía exploratoria y posteriormente una endoscopía, identifi cándose en duodeno foco de sangrado originadopor parásitos, que por su morfología se asume que se trate de Necator americanus. Con este diagnóstico, recibe transfusiones para suestabilizar su hipovolemia y Mebendazol, con buena evolución, remisión del sangrado de tubo digestivo, y buena tolerancia a la alimentación.El “sangrado agudo” por uncinarias, es excepcional, hecho que justifi ca la presentación del caso y permite realizar un recordatorio breve delos mecanismos responsables de ello...

In temperate climate, yungas (intermediate zone between valley and tropical lowland), two blood sucking parasites are prevalent: Necator americanus and Ancylostoma duodenale, responsible for chronic anaemia in children that causes extremely low Hb levels sometimesconsidered as incompatible with life; only in rare cases acute bleeding occurs.We describe the case of a six months old child stemming from Coroico (Nor Yungas) initially with dysentery that becomes complicated by melaena and rectal bleeding originating severe hypovolaemia bordering on shock. After gammagraphy in order to exclude Meckel’s diverticle, the child was submitted to surgical exploration, where no source of bleeding could be found, therefore an explorative laparotomy was performed and later on an endoscopy, where the source of bleeding was identifi ed in the duodenum as caused by the parasite Necator Americanus. With this diagnose, blood transfusions were administered to the child in order to stabilize the hypovolaemia and Mebendazol was given. The evolution was good, the bleeding stopped and feeding was well tolerated.Acute bleeding caused by hook worms is exceptional; therefore we present this case as a short reminder of the responsible mechanisms.
