Background: Experience with administration of synbiotics (prebiotics/probiotics) in patients with severe acute pancreatitis (SAP) has demonstrated immunomodulatory capacity. The aim of this trial was evaluation of the feasibility and perspective of early clinical application of oral synbiotic/prebiotic supplements in patients with SAP., Methods: 90 SAP patients were enrolled during the period from 2005-2008. Patients were stratified according to the feeding mode. CONTROL (n = 32) group received standard whole protein feeding formula. SYNBIO (n = 30) and FIBRE groups (n = 28) received early (within first 24-48 hours) synbiotic or prebiotic supplements. Oral administration of synbiotics or prebiotics was commenced when patients were able to sip water., Results: Daily provided average volume and calories of synbiotic/prebiotic blends were smaller compared to the CONTROL, p = 0.001. Oral administration of synbiotic/prebiotic supplements was associated with lower infection rate (pancreatic and peripancreatic necrosis) compared to the CONTROL, (p = 0.03; p = 0.001), lower rate of surgical interventions, p = 0.005, shorter ICU (p = 0.05) and hospital stay (p = 0.03). Synbiotic supplemented enteral stimulation of the gut resulted in reduced mortality rate compared to the CONTROL, p = 0.02., Conclusion: Early low volume oral synbiotic/prebiotic supplemented enteral stimulation of the gut seems to be a potentially valuable complement to the routine treatment protocol of SAP.

Feasibility of hyperbaric oxygen therapy (HBO) as an efficient and safe adjunct to the standardized treatment protocol and its possible immunomodulatory impact were assessed in the prospective and controlled study of 44 patients with diagnosed acute pancreatitis (AP). The course of the disease was accompanied by systemic inflammatory response syndrome (AIRS) in all the patients on admission. The impact of AP and HBO on homeostasis, the number of performed operations, mortality rates, the levels of two cytokines, intraabdominal pressure, and side effects caused by HBO were evaluated. A treatment group consisted of 22 patients receiving HBO therapy for 3 days (twice a day) using a monoplace chamber under pressures of 1.7-1.9 ATA. Patients (n = 22) in the control group were managed in accordance with the standardized treatment protocol. The authors found more stable homeostasis, decreased mortality rate, and the number of operations in the HBO group. This type of additional therapy, possibly contributed to the decrease of intraabdominal pressure within the first six days after admission. The findings suggest HBO can affect an inflammatory response, by decreasing the levels pro-inflammatory cytokines and increasing those of anti-inflammatory ones.

Introduction: Jejunal feeding is accepted in the treatment of severe acute pancreatitis (AP). Early oral feeding (EOF) is deemed to be detrimental in the early phase of AP. The aim of this study was to assess the safety and effectiveness of EOF in the treatment of AP., Materials and Methods: 29 AP patients were prospectively enrolled within 1.96 days from the onset of disease. APACHE II score, SIRS, MODS, serum CRP and lipase were evaluated. All patients received EOF when gastro-enteric transit was not severely impaired. ICU, hospital stay and main outcomes were assessed., Results: APACHE II score was > or = 8 in 10 patients at the admission ranging 0-13 points for the whole group. Alcohol (62%) and gallstones (38%) were the main etiologic factors. SIRS and MODS were diagnosed in 65% and pleural effusion in 24% of patients. EOF was started on average 3.27 days after admission providing 571 ml (280.0-1115.0 ml) of enteral formula daily for 10.38 days. Median lipase activity was 690 U/l (90-10175 U/l) and CRP concentration reached 91.25 mg/dL (3.5-210 mg/dL) before EOF. Progressive decrease of lipase activity and CRP concentration was observed during the EOF course, reaching median CRP 18.6 mg/L (4.6-96.7mg/L) by discharge. Two patients underwent surgical intervention. Minor side effects of EOF were successfully managed in 4 patients. No mortality was observed., Conclusion: EOF could be a safe and effective alternative of nutritional support in AP patients when gastro-enteric transit is not severely impaired. For better EOF assessment further clinical trials are required.

Objective: We assessed the clinical effectiveness of postoperative enteral stimulation by gut feeding in patients with severe acute pancreatitis (SAP)., Methods: Medical records of 63 patients who were operated on within the past 4 y due to deterioration of SAP were included in this retrospective study. Patients were stratified in gut feeding (GF; n = 33) and standard therapy (ST; n = 30) groups according to the postoperative therapy provided. The GF group received postoperative standard therapy and enteral stimulation by gut feeding, and the ST group received standard therapy only. The Acute Physiology and Chronic Health Evaluation II score, incidence of the systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), daily calories supply, complication rate, and outcomes were analyzed., Results: Patient characteristics did not differ between groups when considering age and severity of the disease. All patients underwent similar surgical interventions. SIRS and MODS were observed initially with the same frequency in both groups. Regression of MODS and a lower postoperative complication rate was observed more often in the GF group. Development of early pulmonary complications was observed in 12.1% to 13.3% in both groups, irrespective of the time of surgery. Subsequently, pulmonary complications developed in 15.2% of GF patients compared with 43.3% of ST patients (P <0.05). Acute renal insufficiency developed similarly in 33.3% of the GF patients and in 26.7% of the ST patients within 3 d after admission. Acute renal insufficiency developed later on only in the ST group (26.7%, P <0.05). Wound- and catheter-related septic complications were considerably more frequent in the ST group (30.0%) than in the GF group (9.1%, P <0.05). Intensive care and hospital stays did not differ. Postoperative gut feeding was associated with 6.1% mortality in the GF compared with 26.7% in the ST (P <0.05)., Conclusions: Enteral stimulation by gut feeding is an effective supplement in the postoperative therapy of patients with SAP.

The aim of the study was to assess whether increased intra-abdominal pressure affects the clinical course and reflects on the effectiveness of the conservative treatment in patients with severe acute pancreatitis. Data on 37 consecutive patients with severe acute pancreatitis that were collected prospectively included APACHE II score, daily measurement of the intra-abdominal pressure, and clinical routine. Group A consisted of 26 patients with intra-abdominal pressure < 25 cm/H2O during their treatment period, and group B consisted of 11 patients with intraabdominal pressure > or = 25 cm/H2O. SIRS, MODS, complication rate and mortality were analysed. The age, APACHE II scores and hospital stay were similar in both groups. ICU stay was 9.1 +/- 9.6 vs. 20.7 +/- 16.8 days in groups A and B, p < 0.05. SIRS and MODS developed less frequently in group A. More pulmonary complications developed in group B, reaching 64% compared to 19% in group A, p < 0.05. Intra-abdominal pressure had negative interrelation with enterally provided volume (r = -0.45, p < 0.001) and positive interrelation with parenterally provided volume (r = +0.27, p < 0.01) in all. Mortality was zero in group A vs. 36% in group B, p < 0.01. Increase of the intra-abdominal pressure is common during the clinical course of severe acute pancreatitis and can be associated with aggressive fluid replacement therapy. Routine measurement of the intra-abdominal pressure is rational in the clinical setting of the ICU and gives additional criteria for the evaluation of the clinical course and the effectiveness of the treatment. Marked increase of the intra-abdominal pressure should be considered a serious prognostic sign in patients with severe acute pancreatitis.

This study assessed the feasibility and effectiveness of jejunal feeding (JF) after surgery due to secondary peritonitis or failed conservative therapy of severe pancreatitis. Of 60 patients, 30 were randomly assigned to receive postoperative JF and the remaining 30 constituted the control group. Acute Physiology and Chronic Health Evaluation II, nutritional intake, systemic inflammatory response syndrome, and outcomes were measured. Patients in JF group received the daily mean of 1294.6 (362.6) kcal including 830.6 (372.7.0) kcal enterally, versus 472.8 (155.8) kcal daily in the control group (P < 0.0001). There were fewer complications in the JF patients, with no significant difference; length of stay in the intensive care unit and in the hospital did not differ. The frequency of systemic inflammatory response syndrome was similar in both groups, but outcomes differed. The first surgical intervention resulted in 3.3% of relaparotomies in JF patients, caused by unresolved peritonitis, versus 26.7% in the control subjects (P = 0.03). Recovery of bowel transit took significantly less time in the JF patients (mean: 54.6 h versus 76.8 h in control subjects, P = 0.01). JF resulted in 3.3% mortality as opposed to 23.3% in the control group (P = 0.05). In conclusion, JF is feasible and effective in postoperative treatment of patients due to secondary peritonitis or severe pancreatitis. Improved bowel and peritoneal function could be the main impact of JF.

Objective: To find out whether postoperative enteral feeding is safe and effective in patients with severe pancreatitis., Design: Prospective randomised trial., Setting: Teaching hospital, Latvia., Subjects: 29 patients who had been operated on for severe pancreatitis., Interventions: They were randomised to have either enteral nutrition and conventional intravenous fluids postoperatively (n = 11), or conventional intravenous fluids only (n = 18). 17 additional patients who had had major abdominal operations for other conditions were also given enteral nutrition and intravenous fluids and comprised the control group., Main Outcome Measures: Nutritional intake, duration of stay in intensive care (ICU) and hospital morbidity, mortality, and outcome., Results: 1 patient died of the 11 given enteral nutrition combined with conventional intravenous fluids, compared with 5/18 given fluids only. The pattern of bowel transit in the fed group did not differ from that in the control group., Conclusion: Postoperative enteral nutrition seems to be safe and effective in patients with severe pancreatitis and may improve survival. Our results suggest that enteral and parenteral nutrition may complement each other in seriously ill patients.

Introduction. Recognition of severe acute pancreatitis (SAP), intensive care, shifting away from early surgical treatment, and monitoring of the intra-abdominal pressure (IAP) is important in the management of SAP. The aim of our study was retrospective evaluation and critical assessment of the experience with SAP management protocol involving new strategy in the university hospital. Methods. Protocols of 274 SAP patients treated in our institution during the last eight years were reassessed. APACHE II, CRP and SOFA score, IAP, pulmonary complications, ventilatory support and infection rate were evaluated. The success of the conservative treatment, surgical interventions and mortality was analysed comparing period 1 from 1999 to 2002 and period 2 from 2003 to 2006. Results. More patients with necrotising SAP were treated in period 2. The average CRP and SOFA score was higher in period 2, p=0.018; p=0.011. A total of 139 patients underwent continuous veno-venouse haemofiltration (CVVH) as a component of fluid resuscitation and IAP control. Application of CVVH increased in period 2, p<0.005. Only 5-8% of patients were managed with ventilatory support. The overall infection rate decreased in period 2 comprising 21%, p<0.005. Success rate of the conservative therapy reached 69% in period 2, p<0.01. Surgical treatment was performed in 41% of patients in period 1 vs. 19% in period 2, p<0.001. Overall mortality was 19%, with a reduction to 12% in year 2006. Conclusion. The conservative protocol-based approach is a rational treatment strategy for the management of SAP and can be successfully implemented in the setting of the university hospital.

Background. Continuous veno-venous haemofiltration (CVVH) could be reasonable for attenuation of systemic complications in severe acute pancreatitis (SAP). The aim of the study was implementation and feasibility assessment of the CVVH in the treatment protocol of SAP. Patients and methods. CVVH was applied to 111 SAP patients during 2000-2005. APACHE II, systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), serum lipase, C-reactive protein (CRP), complication rate and main outcomes were analysed comparing two periods. Results. Overall, 39 patients corresponded to Balthazar grade E SAP and 72 patients to necrotizing SAP (NSAP), with an average APACHE II score of 7 and 8.5, respectively, on admission. CVVH was started within 48 h in 82% of patients. Duration of CVVH was significantly augmented in NSAP patients during the routine period, comprising 92 h (p=0.006). The clinical presentation of SIRS and MODS was similar in both periods, with more initial pulmonary dysfunctions in NSAP (p=0.048). Peripancreatic infection decreased in the routine period; surgical interventions were performed in 34.8% vs 72.4% of patients. Hospital stay comprised on average 15.9 days for grade E SAP and 29.4 days for NSAP in the routine period, with overall mortality of 10.26% and 30.5%, respectively. Discussion. Application of CVVH in the treatment protocol of SAP is obscure due to relative invasiveness, a poorly understood mechanism of action and scarce clinical experience. We conclude that early pre-emptive application of CVVH is safe and feasible in the treatment of SAP. Duration of the procedure seems to be essential. Randomized clinical trials are justified. Our results are in favour of clinical application of CVVH in the treatment of SAP. [ABSTRACT FROM AUTHOR]

Increased intra-abdominal pressure (IAP) is detrimental for the recovery of organ function in trauma and emergency patients. The aim of this study was to assess the correlation between the dynamics of IAP and organ dysfunction in severe acute pancreatitis (SAP).Management of SAP between 2000 and 2004 was analysed. SAP was classified according to Atlanta 1992. Organ dysfunction, systemic inflammatory response syndrome (SIRS) and outcomes in relation to the IAP were assessed. IAP was measured indirectly.A total of 65 patients, with an average APACHE II score of 6.44, complied with the Atlanta criteria. In all, 34 patients received conservative treatment and 31 were operated. SIRS was observed in 59 cases and multiple organ dysfunction syndrome (MODS) in 61 cases. IAP was significantly higher in the 25 most complicated patients requiring renal replacement therapy (RRT), compared with 40 patients without RRT, 31.72 vs 21.4&ThickSpace;cm/H 2 O ( p =0.037). IAP interrelated positively with SOFA score (r = + 0.371, p [ABSTRACT FROM AUTHOR]
