- O balão intragástrico nas formas graves de obesidadePublication . Almeida, N; Gomes, D; Gonçalves, C; Gregório, C; Brito, D; Campos, JC; Gouveia, H; Freitas, DIntroduction: In patients with morbid obesity the intragastric balloon (IGB) can be a “bridge” to surgery or a temporary treatment in patients who are not candidates for surgery. Objective: Evaluate IGB efficacy in morbidly obese patients. Patients and Methods: In 2003/2004 seventeen IGB Bioenterics ® filled with normal saline and methylene blue were placed in 17 patients [11 women, median age was 49.2 (27-69 years); median body mass index was 55.6 (40.2-74.2 Kg/m2)], followed by nutritionists and/or endocrinologists. They had previously tried dietetic and/or pharmacological measures with limited results. Co-morbidities were present in 13 (76.5%). Results: Eight (47%) patients presented nausea/vomiting in the first 24-72h that persisted in 4 (23.5%) leading to dehydration and pre-renal insufficiency and forcing premature removal of the balloon (0.5 to 4 months). In the other patients, the device was removed at 6 months treatment (in 1 patient at 10 months). All patients suffered weight loss (5-70 Kg); median loss-19.6 Kg (p<0.001). No cases of spontaneous deflation/displacement occurred. Six (35.3%) underwent bariatric surgery. Conclusions: The IGB is a useful method for weight loss in morbidly obese patients. Nausea and vomiting are the most common complications. Although desirable, subsequent surgery is not always performed.
- Groove Pancreatitis with Biliary and Duodenal Stricture: An Unusual Cause of Obstructive JaundicePublication . Gravito-Soares, M; Gravito-Soares, E; Alves, A; Gomes, D; Almeida, N; Tralhão, G; Sofia, CINTRODUCTION: Groove pancreatitis is an uncommon cause of chronic pancreatitis that affects the groove anatomical area between the head of the pancreas, duodenum, and common bile duct. CLINICAL CASE: A 67-year-old man with frequent biliary colic and an alcohol consumption of 30-40 g/day was admitted to the hospital complaining of jaundice and pruritus. Laboratory analysis revealed cholestasis and the ultrasound scan showed intra-hepatic biliary ducts dilatation, middle third cystic dilatation of common bile duct, enlarged Wirsung and pancreatic atrophy. The magnetic resonance cholangiopancreatography showed imaging findings compatible with groove pancreatitis. An esophagogastroduodenoscopy later excluded duodenal neoplasia. He was submitted to a Roux-en-Y cholangiojejunostomy because of common bile duct stricture. Five months later a gastrojejunostomy was performed due to a duodenal stricture. The patient remains asymptomatic during follow-up. DISCUSSION: Groove pancreatitis is a benign cause of obstructive jaundice, whose main differential diagnosis is duodenal or pancreatic neoplasia. When this condition causes duodenal or biliary stricture, surgical treatment can be necessary.
