Abstract
Antibiotics that are efficacious for infectious pancreatitis are present in pancreatic exocrine secretion (PES) after intravenous administration and above minimal inhibitory concentrations. We measured concentrations of four antibiotics by tandem liquid chromatography-mass spectroscopy in plasma and PES after enteral administration to juvenile pigs with jugular catheters and re-entrant pancreatic-duodenal catheters. Nystatin, which is not absorbed by the intestine nor used for infectious pancreatitis (negative control), was not detected in plasma or PES. Concentrations of amoxicillin increased in plasma after administration (p = 0.035), but not in PES (p = 0.51). Metronidazole and enrofloxacin that are used for infectious pancreatitis increased in plasma after enteral administration and even more so in PES, with concentrations in PES averaging 3.1 (±0.5)- and 2.3 (±0.6)-fold higher than in plasma, respectively (p's < 0.001). The increase in enrofloxacin in PES relative to plasma was lower after intramuscular administration (1.8 ± 0.5; p = 0.001). The present results demonstrate the presence of a selective and concentrative enteropancreatic pathway of secretion for some antibiotics. Unlike the regulated secretion of bile, the constitutive secretion of PES and intestinal reabsorption may provide a continuous exposure of pancreas tissue and the small intestine to recirculated antibiotics and potentially other therapeutic molecules. There is a need to better understand the enteropancreatic recirculation of antibiotics and the associated mechanisms.

Responses of Ileal and Fecal Microbiota to Withdrawal of Pancreatic Enzyme Replacement Therapy in a Porcine Model of Exocrine Pancreatic Insufficiency. Int J Mol Sci 2022; 23:ijms231911700.

Abstract
Little is known regarding the interplay between microbiota and pancreas functions in humans as investigations are usually limited to distal sites, namely the analyses of fecal samples. The aim of this study was to investigate both ileal and fecal microbiota in response to pancreatic enzyme replacement therapy (PERT) in a porcine model of exocrine pancreatic insufficiency (EPI). PERT was stopped for ten days in ileo-cecal fistulated minipigs with experimentally induced EPI (n = 8) and ileal digesta as well as fecal samples were obtained before withdrawal, during withdrawal and after the reintroduction of PERT. Profound community changes occurred three days after enzyme omission and were maintained throughout the withdrawal phase. A reduction in α-diversity together with relative abundance changes in several taxa, in particular increases in Bifidobacteria (at both sites) and Lactobacilli (only feces) were observed. Overall, dysbiosis events from the ileum had accumulating effects in distal parts of the gastrointestinal tract with additional alterations occurring only in the colon. Changes were reversible after continuing PERT, and one week later, bacterial communities resembled those at baseline. Our study demonstrates the rapid and profound impacts of enzyme withdrawal in bacterial communities, contributing to our understanding of the interplay between pancreas function and microbiota.

Abstract
In a pig model, pancreatic duct ligation (PL) leads to a complete loss of exocrine function, causing an exocrine pancreatic insufficiency (EPI) without affecting endocrine function, allowing research of clinical effects and therapy options. This study aimed to investigate effects of experimentally induced EPI in juvenile pigs on digestion and intestinal morphology. Eight female juvenile cross-bred pigs (BW 54.8 kg at the start of the study) were included. Three animals were considered as a control (CON group), and in five animals the ductus pancreaticus accessorius was ligated (PL group). During the 10-week trial period, body weight and body measurements were recorded regularly. At the end of the trial, gastrointestinal tract (GIT) was investigated macroscopically and histologically and weight and digesta samples of individual segments were obtained. The pigs in the CON showed a significantly higher apparent total tract digestibility of crude protein and crude fat (87.8 and 79.9%, respectively) compared to PL (52.4 and 16.6%, respectively). Significant differences were noted in relative weights of duodenum, jejunum and colon (with and without digesta) and also in absolute weights of jejunum and colon. The mean number of nuclei in the transverse section in stratum circulare were significantly higher in all intestinal segments in CON compared to PL. Overall, EPI results in impaired nutrient digestibility with a greater filling of the GIT with digesta. The elongation of the small intestine does not represent "stretching" of the intestine, but rather increased synthesis of intestinal tissue.

Abstract
Small intestinal bacterial overgrowth (SIBO), characterized by the presence of excessive bacteria in the small intestine, is typically described as a malabsorptive syndrome occurring in the context of gut stasis syndromes. SIBO is now considered to be a disorder associated with diverse clinical conditions without classic risk factors for SIBO and a cause of several nonspecific gastrointestinal and nongastrointestinal symptoms. Because there is currently no gold standard for diagnosing SIBO, its prevalence and role in the pathogenesis of other diseases remain uncertain; as does optimal treatment of patients with relapsing symptoms.

Abstract
BACKGROUND The aims of the present study were: (1) to assess the feasibility and safety of emergency endoscopic retrograde cholangiopancreatography (ERCP) and pancreatic duct (PD) stenting with small-caliber stents as a bridging procedure in acute biliary pancreatitis (ABP) patients in whom biliary endoscopic sphincterotomy (EST) proved difficult, failed or was contraindicated, and (2) to compare the clinical outcome of those patients having emergency ERCP with and without pancreatic stent. METHOD Eighty-seven consecutive patients with ABP were referred for emergency ERCP. In 60 of these ABP patients, ERCP, EST, and stone extraction (if necessary) were performed without PD stenting. In the remaining 27 patients, small-caliber (3-5 F, 4 cm) pancreatic stent insertion was initially applied. All patients were hospitalized for medical therapy and were followed up. RESULTS The mean ages, the initial symptom-to-ERCP times, the Glasgow severity scores, and the peak amylase and CRP levels at initial presentation were not significantly different in the ERCP + EST with PD stent group versus the ERCP + EST without PD stent group. More importantly, the complication rate was significantly lower in the ERCP + EST with PD stent group versus the ERCP + EST without PD stent group (7.4% vs. 25%); while the mortality rates (0% vs. 6.7%) were comparable, reasonably low, and demonstrated no statistically significant differences. CONCLUSIONS Temporary PD stenting with small-caliber stents is a safe and effective procedure that may afford sufficient PD decompression to reverse the process of ABP and serve as a bridging procedure in severe ABP in patients with failed, complicated, or contraindicated biliary EST.

Abstract
Background/Aim Pancreatic sepsis secondary to infected necrosis, pseudocyst, or pancreatic abscess is a well-known clinical entity. Acute suppuration of the pancreatic duct (ASPD) in the setting of chronic calcific pancreatitis and pancreatic ductal obstruction with septicemia is a rare complication that is seldom reported. It is our aim to report a case of ASPD with Klebsiella ornithinolytica, in the absence of pancreatic abscess or infected necrosis. Case Report A 46-year-old Asian-Indian man with chronic tropical pancreatitis who was admitted with recurrent epigastric pain that rapidly evolved into septic shock. A CT scan of abdomen revealed a dilated pancreatic duct with a large calculus. Broad-spectrum antibiotics, vasopressors and activated recombinant protein C were initiated. Emergency ERCP showed the papilla of Vater spontaneously expelling pus. Probing and stenting was instantly performed until pus drainage ceased. Repeat CT scan confirmed the absence of pancreatic necrosis or fluid collection, and decreasing ductal dilatation. Dramatic clinical improvement was observed within 36 hours after intervention. Blood cultures grew Klebsiella ornithinolytica. The patient completed his antibiotic course and was discharged. Conclusion ASPD without pancreatic abscess or infected necrosis is an exceptional clinical entity that should be included in the differential diagnosis of pancreatic sepsis. A chronically diseased pancreas and diabetes may have predisposed to the uncommon pathogen. The presence of intraductal pancreatic stones obstructing outflow played a major role in promoting bacterial growth, suppuration and septicemia. Immediate drainage of the pancreatic duct with endoscopic intervention is critical and mandatory.

Abstract
The objective of this study was to determine the influence of the level of feed intake and a 2-d feed restriction period on the postweaning adaptation of pancreatic exocrine secretions. At 33 d of age, 18 piglets fitted with 2 permanent catheters (for pancreatic juice collection and reintroduction) were weaned and allocated to 1 of the following 2 dietary treatments for 5 d: restricted feed allocation (restricted) or gradually increasing feed allocation (control). Pancreatic juice was collected daily during both basal and prandial periods. The basal period was defined as the period from 1400 to 1700 h (i.e., 5 to 8 h after the morning meal), whereas the prandial period was defined as the period from 30 min before to 60 min after the morning meal (given at 0900). Digestive enzyme activities and antibacterial activity were determined. Pancreatic protein secretion was 44% less (P < 0.05) in restricted piglets than in control piglets during the basal period. Trypsin secretion was affected by feed-restriction of piglets. The meal did not affect protein and trypsin secretions in restricted piglets, whereas at d 3 postweaning, protein and trypsin secretions and trypsin specific activity in control piglets were 9-, 105-, and 25-fold greater (P < 0.001) during the first 30 min after the meal than before the meal. Lipase and amylase secretions were not affected by variations in feed intake. The secretion of antibacterial activity in restricted piglets was greater (P < 0.05) than that of control piglets only at d 5. The extended feed restriction period increased the basal secretion of antibacterial activity (P = 0.09) and postprandial secretion of amylase (P = 0.05). In conclusion, a low level of feed intake during the early postweaning period decreased pancreatic protein and trypsin secretions, whereas a 2-d feed restriction period enhanced secretions of amylase and antibacterial activity. In addition, our results indicate that during periods of dietary adaptation, such as at weaning, measurements of enzyme activities in the tissue do not accurately reflect the enzyme secretion.
