Extensive Fatty Replacement of the Pancreas (Pancreatic Lipomatosis) in a Dog.

A 12-year-old neutered female mixed-breed dog was referred for occasional vomiting that had increased progressively in frequency over the past 3 months. Palpation of the abdomen revealed a firm mass of unknown aetiology, located within the cranial to mid abdomen, while abdominal surgical exploration revealed a well-defined abdominal mass of pancreatic origin. The pancreatic mass caused lateral displacement of the duodenum as well as medial displacement of the pylorus, resulting in impairment of pyloric outflow. Further examination revealed a firm, poorly vascularized and coarsely lobulated structure. The histopathological findings were consistent with severe pancreatic lipomatosis and atrophy. Immunohistochemically, the remnant pancreatic cells were positive for cytokeratins AE1/AE3 and glucagon, and negative for insulin. Routine follow-up with the referring veterinarian showed no evidence of postoperative complications, but the dog continued to deteriorate further and died despite medical management. Pancreatic lipomatosis is a rare condition in small animal practice. The aetiology or predisposing factors have not been identified in animals.

[Gastric necrosis, rare complication after laparoscopic gastric banding--case report]. / Necroza gastrica, complicatie rara dupa gastric banding--prezentare de caz.

In the last years, laparoscopic gastric banding has become a popular surgical option for morbidly obese patients, because of the minimally invasive and easy surgical technique, its reversibility, and the possibility to calibrate the stoma. Gastric necrosis, as a complication of laparoscopic gastric banding, has been rarely reported. We present the case of a 34 -year-old pregnant patient (18 week pregnancy) with 5 days history of abdominal pain. She had undergone laparoscopic adjustable gastric banding 24 months earlier with a body mass index (BMI) of 43 kg/m2. Diagnostic workup was very difficult because the patient was pregnant and we can use only ultrasonography and clinically signs. After initial conservative management, the patient underwent urgent surgery and we found an anterior gastric prolapse through the band with necrosis of the herniated stomach. A longitudinal (sleeve) gastrectomy was performed. The postoperative evolution was god and the patient left our clinic after 9 day. Emergency sleeve gastrectomy could represent a good option to treat, in a safe way.
