RESUMO
Introduction: Groove pancreatitis (GP) is an unusual subtype of chronic pancreatitis that affects the groove area. Differential diagnosis between groove pancreatitis and pancreatic carcinoma (PC) can be challenging, both clinically and radiologically. Our aim is to report the first case of GP debut with upper gastrointestinal bleeding (UGB). Case Report. A 53-year-old man with a personal history of alcohol and tobacco abuse and chronic pancreatitis was admitted to the hospital for epigastric abdominal pain. A computed tomography scan showed a locally advanced neoformative lesion in the distal stomach. The patient presented melena, arterial hypotension, and 4.4 g/dl of hemoglobin. An upper gastrointestinal endoscopy showed a neoformative ulcerated lesion at the duodenal bulb without active bleeding. Biopsies were taken, and histopathological analysis did not show malignancy. A cephalic pancreaticoduodenectomy was performed, and the postoperative period was uneventful. Histopathological analysis revealed a segmental GP. Discussion. GP is an uncommon entity, and its clinical and radiological presentation mimics PC. However, with advances in imaging tests, several radiological criteria have been described to distinguish GP from PC preoperatively. Although some authors recommend a stepwise management with initial conservative therapy, a therapeutic strategy has not yet been established. Conclusion: GP is an uncommon type of focal pancreatitis that should be considered as a differential diagnosis of PC. We report the first clinical case of GP whose debut with UGB presented a greater diagnostic and therapeutic challenge.
RESUMO
The medium arcuate ligament syndrome is a rare disorder that results from luminal narrowing of the celiac artery by the insertion of diaphragmatic muscle or the celiac nerve plexus. The syndrome is characterized by weight loss, postprandial abdominal pain, nausea, vomiting and an epigastric murmur. Surgical management involves the complete division of the medial arcuate ligament. We present two cases satisfactorily treated by laparoscopic surgery. The role of minimally invasive surgery in the treatment of this syndrome is a safe alternative approach to open surgery.
El síndrome de ligamento arcuato medio es un trastorno poco frecuente que resulta del estrechamiento luminal de la arteria celíaca por la inserción de fibras musculares diafragmáticas o bandas fibrosas del plexo nervioso celíaco. El síndrome se caracteriza por pérdida de peso, dolor abdominal posprandial, náuseas, vómitos y un soplo epigástrico. El manejo quirúrgico implica la división completa del ligamento arqueado mediano. Presentamos dos casos tratados satisfactoriamente mediante cirugía laparoscópica. El papel de la cirugía mínimamente invasiva en el tratamiento de este síndrome es una vía de abordaje segura alternativa a la cirugía abierta.
