Pancreatitis experimental en el opossum. Rol de la esplacnicectomía previa en la respuesta inflamatoria / Experimental pancreatitis in opossum. Rol of the previus splanicectomy in inflamatory response

BACKGROUND: The role of the Autonomous Nervous System in the immunologic and inflammatory response is still an issue of discussion. Furthermore, the physiopathologic mechanisms involved are still unknown. Acute pancreatitis (AP) does not escape this disconcert. In fact, like in every severe acute inflammatory process, its discontrol could be responsible of the high morbidity and mortality rates. OBJECTIVE: To assess to which degree bilateral splanchnicectomy changes the course of acute inflammatory response in AP. METHOD: Prospective research. RESULTS: The following parameters were evaluated: red blood cell count, white blood cell count, calcium, glucemia, urea, aminase, lypase and liver enzymes. Macroscopy and microscopy views of the pancreas were also obtained. The leucocitary response was abolished, and the calcium levels dropped to a lesser degree. CONCLUSIONS: Bilateral splanchnicectomy prior to unchaining AP had a beneficial effect, Its mechanism of action could have been through the disconnection of the respective reflex arches

[Pseudo acute pancreatitis: a syndrome mimicked by a multiple parasitic duodenitis. Analysis of 7 case]. / Pseudo-Pancreatitis Aguda Edematosa: síndrome mimetizado por una duodenitis parasitaria múltiple. Análisis de 7 casos.

INTRODUCTION: The aim of this presentation was to analyze a clinical syndrome characterized by repeated episodes of upper abdominal pain, markedly increased levels of both total amylase and lipase, but with normal values of pancreatic isoamylase. Besides, with the lack of morphologic changes of the pancreatic gland, either by ultrasound, abdominal tomography, or Nuclear Magnetic Resonance. MATERIAL, METHODS AND RESULTS: Five female and two male patients, with an average age of 51 +/- 3 were studied. All had been diagnosed as having acute edematous pancreatitis (ranson score < 3). Laboratory tests had disclosed eosinophilia (5-30%); total amylasemia (1547 +/- 398 UA/l); lipasemia (857 +/- 499 UBL/L); normal pancreatic isoamylase (72 +/- 18 UA/L). Upper endoscopy showed nonspecific signs of duodenitis sometimes with duodenal erosions. Collection studies, pre and post Sorbitol, disclosed an unexpected multiple parasitic infestation, e.g.: giardias, ascaris, amoeba, hymenolepis nana. This finding was always suggestively associated with abundant sludge (bilirrubinate cholesterol and oxalate crystals). All patients, after having been submitted to the appropriate antiparasitic medication, were rapidly relieved of their symptoms and remained free of episodes of abdominal pain. CONCLUSIONS: When the fact that all our patients had normal pancreatic isoamylase levels and lack of any morphologic distortion of the pancreatic parenchyma is associated to the notion that total amylase and lipase may have as a source the gastrointestinal mucosa, it appears as a logical inference that the clinical syndrome here discussed is indeed primarily a reflection of an extrapancreatic disease, essentially of parasitic duodenitis.

[Acute experimental pancreatitis in the opossum. The role of prior truncular vagotomy on the inflammatory response]. / Pancreatitis aguda experimental en el opossum. Rol de la vagotomía troncular previa en la respuesta inflamatoria.

BACKGROUND: Acute pancreatitis (AP) is a common cause of admission to the emergency room. Its etiopathogeny is poorly understood. The pancreatic inflammatory response in this process is unclear. The influence of the autonomic nervous system is a controversial issue. AIMS: To demonstrate the effects of truncular vagotomy on AP due to duodenal distention in the South American opossum. PLACE OF APPLICATION: Department of experimental surgery (Churruca-Visca Hospital) INEUCI (Neuroscience Institute, CONICET, UBA). POPULATION: Male and female South American opossum divided into: a control group (7 animals); group A: truncular vagotomy and pyloroplasty seven days after the onset of AP (7 animals). Group B: truncular vagotomy and pyloroplasty 30 days after provoking AP (7 animals). Group C: truncular vagotomy and pyloroplasty 45 days after the onset of AP (7 animals). METHODS: Acute pancreatitis was caused by duodenal distention of the second portion by inserting a Foley catheter through a gastrostomy. CONCLUSIONS: The method of provoking AP is original. The influence of autonomous nervous system is being underestimated in most of the literature available.

[Biliary acute pancreatitis: an etiopathology and evolution review of 148 cases]. / Pancreatitis aguda biliar. Una revisión etiopatogénica y evolutiva de 148 casos.

BACKGROUND: A retrospective analysis of the etiologic factors and physiopathogenic mechanisms underlying an acute biliary pancreatitis episode put in evidence the complexity of the attempt to acquire a clear understanding of the entity. In this presentation the authors try to re-examine the main factors involved in the triggering of the disease. Besides the classic theories and their own approach to the management of an acute pancreatic inflammation episode are discussed. AIMS: The main purpose of this endeavor was to identify and discuss the etiopathogenic mechanisms that were prevalent in a series of 148 patients observed and treated in a 10 years period. Besides, another distinctive aim was to analyze their evolution and somehow to try to assess their probable prognosis. PLACE OF APPLICATION: Close community. POPULATION: The whole group of patients that were admitted with the diagnosis of acute pancreatitis in the time period comprised between 1987-1997. METHODS: The acute pancreatitis subgroups and their respective number of patient included were the following: BILIARY ACUTE PANCREATITIS 140 CASES POST ERCP 8 CASES CONCLUSIONS: As a result of the present reviewing endeavour several observations deserve to be pointed out: a. The pancreatic gland undoubtedly is a neuroendocrine organ, that is subjected to complex neural and hormonal influence. b. Undeniably, the involvement of the autonomic nervous system in the physiopathogenic mechanism of acute pancreatitis has been surprisingly disregarded. c. The biliary acute pancreatitis variant is the most frequent. What we consider a simplification is to accept the Opie's postulation without taking into account the intermediate steps, centered on autonomic reflexes, that ultimately lead to the acute inflammatory lesions. d. Although without an absolute proof, it is undeniable that "stress" is a primary etiology in some cases of acute pancreatitis. e. We favor the idea that the pancreas functional status influences on the extension and intensity degree of the acute pancreatic inflammatory lesions.

[Is there pancreatic regeneration? Morphological and functional certification after a corporocaudal splenopancreatectomy/]. / Existe la regeneración pancreática? Certificación morfológica y funcional luego de una esplenopancreatectomía corporocaudal.

INTRODUCTION: The process of pancreatic regeneration, well known and accepted, is less known than the hepatic and includes different mechanisms and factors. Pancreatic regeneration is better known in acute pancreatitis. After an extensive pancreatic necrosis, the morphological and functional regeneration is assessed by dynamic computed tomography associated with normalization of glycemia and the exocrine function. Different groups identified and evaluated experimentally and clinically the actions of multiple factors involved in the process of pancreatic regeneration. Even difficult to assess, pancreatic regeneration after partial pancreatectomy is well documented and of capital importance. CASE REPORT: A 57-year-old woman with discomfort in the upper-left abdominal quadrant. CT scans showed a tumor in the body and tail of the pancreas adherent to the spleen. Preoperative CA 19-9 was normal. She was operated on and the tumor resected en bloc with the spleen. Only the head of the pancreas was preserved. Intraoperative pathological examination of the specimen showed a mucinous cistoadenoma with no malignant degeneration. Postoperative course was uneventful and discharged at p.o. day 10, with ongoing diabetes. Four month later she presented pain in the upper-left quadrant with hyperamylasemia. CT scans showed a normal body and tail with an image of pseudocyst at the top of the pancreatic tail. One year after the initial surgery she remained asymptomatic, without diabetes and with no dietary restrictions. Further CT controls showed images of the entire regeneration of the body and tail of the pancreas. DISCUSSION: Several phenomena are well known and accepted to be associated with the regeneration of the pancreas. In 1965, Tiscornia et al demonstrated the restoration of the pancreatic exocrine function after 6 weeks of selective occlusion of the pancreatic duct. The authors proposed pancreatic regeneration as responsible of morphological, histological and functional changes observed in operated patients where the pancreatic duct was decompressed by an anastomosis to the small bowel and constitutes the rational basis for surgical treatment of chronic pancreatitis. Several humoral factors seems to be involved in pancreatic regeneration acting by a specific receptors-mechanisms, like Bombesin, Octeotride, FGF (Fibroblast Growth Factor) and TGF (Transforming Growth Factor). Friess et al demonstrated increased levels of TGF in acute pancreatitis and considered it to be responsible of the pancreatic regeneration. Waguri et al experimentally demonstrated a double mechanism involved in the regeneration of B-cells: cellular and humoral ways could vary according to different situations. Less evident are the mechanisms involved after surgical pancreatic resection. Kato et al demonstrated the importance of zinc after partial pancreatic resection in dogs. Up to now, there are no other associations experimentally nor in humans. Our case showed in several CT scans control the presence of a normal pancreatic body and tails after a splenopancreatectomy, with restoration of endocrine and exocrine functions. Probably, several mechanisms were involved in this case. Further investigations will elucidate the answered. CONCLUSIONS: Pancreatic regeneration was confirmed by CT scans images and also functionally after an extensive resection. Future similar findings could be of great clinical importance.
