IntroductionPancreatic pseudocyst is one of the most frequent late complications after acute or chronic pancreatitis, with an average incidence between 6.6-20% in some series depending on the origin.1 It is defined as an encapsulated collection of extravasated pancreatic exocrine secretions with a non-epithelial cover, it is presented in the course of 4 to 6 weeks after the acute pancreatitis episode and almost 85% presents spontaneous resolution. 2 In the other 15% of cases the endoscopic or surgical drainage is necessary to avoid significant complications associated like hemorrhage, rupture or splenic vessels thrombosis.

Case reportA female of 45 years old presented to emergency room for intense abdominal pain the last 8 hours that did not diminished with analgesic consumption. She had pathological background of acute biliary pancreatitis 8 weeks ago, and underwent laparoscopic cholecystectomy 2 days after resolution of this. Patient refers that the last two weeks she noticed postpandrial fulfill and a mild epigastric pain, constant and no related with any factor that she could identify. The last two days the abdominal pain increase without irradiation and she began with throwing after food intake. At physical exam she had dehydrated tissues and mucous membranes, with adequate ventilation, 24 breathings per minute secondary to pain, abdomen with distention in epigastrium and with a palpable mass at this level of about 12 centimeters in diameter, it can be mobilized partially and increase the pain at palpation. The rest of the physical exam was normal. A CT scan was requested, and reported a collection in the front wall of the pancreas of 160x80x73mm and a volume of 430cc, with a thick wall (6mm) and heterogeneous hypo-echogenic content (Figures 1-3). A pancreatic pseudocyst was diagnosed and a laparoscopic approach was decided according to our previous experience in the development of this technique and the good results. A transgastric approach was performed with previous opening of the anterior gastric wall (Figure 4) ( Figure 5), drainage of 500cc of pancreatic liquid, and an anastomosis performance between pseudocyst anterior wall and gastric posterior wall with prolene 00 with a continuous stitch (Figure 6), and posterior close of the anterior gastric wall with another continuous stich of the same suture (Figure 7). Total bleeding was estimated in 20cc and surgical time was 120 minutes, 40 minutes less than our first case. Only four trocar ports were used, 2 of 5mm (epigastric and in right hypochondrium) and 2 of 12 mm (umbilical and left hypochondrium). Patient began feeding after 48 hours and was discharged at 72 hours uneventfully. At four months follow up she stills asymptomatic.
AbstractBackground: Pancreatic pseudocyst is a frequent complication in patients after acute pancreatitis, with spontaneous resolution in more than 80 % along the next 6 weeks after acute disease. In case of persistence or specific indications the surgical management is considered.
