Enhanced recovery in the management of mild gallstone pancreatitis: a prospective cohort study

Pancreatic Necrosis Infection as a Determinant of Multiple Organ Failure and Mortality in Acute Pancreatitis

Several recommendations and data on the treatment of acute necrotizing pancreatitis (ANP) are conflicting and different surgical approaches continue to exist. We conducted a study on 148 patients with ANP, who were divided into two groups: the main group (n = 95) when the tactics of the step-up approach were applied with the principles of the concept of Enhanced Recovery After Surgery (ERAS) in order to determine this approach on effectiveness in reducing complications and 30-day mortality (2017-2022); the comparison group (n = 53) when the same tactic of the treatment was used without ERAS principles (2015-2016). Treatment time for the main group in the intensive care unit was minimized (p ≤ 0.004); it has been shown to reduce the frequency of complications in these patients (p < 0.001) requiring conservative or surgical treatment without general anaesthesia (Clavien-Dindo I-IIIa); no statistically significant differences were observed for the total incidence of Clavien-Dindo IIIb-IVb complications (p > 0.05); the median duration of treatment for patients in the primary group was 23 days, and in the reference group-34 days (p ≤ 0.003). Pancreatic infections have been observed in 92 (62.2%) patients and gram-negative bacteria predominated in the overall pathogen structure with 222 (70.7%) strains. The only evidence of multiple organ failure before (AUC = 0.814) and after surgery (AUC = 0.931) was found to be predictive of mortality. Antibiotic sensitivity of all isolated bacteria better understood local epidemiology and identified the most effective antibiotics when treating patients.

Impact of hospital characteristics on best-practice adherence for gallstone pancreatitis: a nationwide analysis

BACKGROUND

Current guidelines recommend cholecystectomy during the index admission for gallstone pancreatitis, and a growing body of evidence indicates that patients benefit from cholecystectomy within the first 48 h of admission. We examined the impact of hospital characteristics on adherence to these data-driven practices.

METHODS

We queried the National Inpatient Sample for patients admitted for gallstone pancreatitis between October 2015 and December 2018. Patients who underwent same-admission cholecystectomy were identified by procedure codes. Cholecystectomies within the first two days were classified as early cholecystectomies. Multivariable logistic regression was used to determine the association between hospital characteristics and adherence to these practices.

RESULTS

Of 163,390 admissions for gallstone pancreatitis, only 90,790 (55.6%) underwent cholecystectomy before discharge. Mean time from admission to cholecystectomy was 2.9 days; 27.0% of patients (44,005) underwent early cholecystectomy. Odds of same-admission cholecystectomy were highest in large hospitals (OR 1.21, 95% CI 1.13-1.28), urban teaching centers (OR 1.33, 95% CI 1.21-1.46), and the South (OR 1.70, 95% CI 1.57-1.83). Odds of early cholecystectomy did not vary with hospital size, urban-rural status, or teaching status but were highest in the West (OR 1.98, 95% CI 1.80-2.18).

CONCLUSION

Best-practice adherence for cholecystectomy in gallstone pancreatitis remains low despite an abundance of evidence and clinical practice guidelines. Active interventions are needed to improve delivery of surgical care for this patient population. Implementation efforts should focus on small hospitals, rural areas, and health systems in the Northeast region.

Plasmatic Oxidative and Metabonomic Profile of Patients with Different Degrees of Biliary Acute Pancreatitis Severity

Acute pancreatitis (AP) is an inflammatory process of the pancreas with variable involvement of the pancreatic and peripancreatic tissues and remote organ systems. The main goal of this study was to evaluate the inflammatory biomarkers, oxidative stress (OS), and plasma metabolome of patients with different degrees of biliary AP severity to improve its prognosis. Twenty-nine patients with biliary AP and 11 healthy controls were enrolled in this study. We analyzed several inflammatory biomarkers, multifactorial scores, reactive oxygen species (ROS), antioxidants defenses, and the plasma metabolome of biliary AP and healthy controls. Hepcidin (1.00), CRP (0.94), and SIRI (0.87) were the most accurate serological biomarkers of AP severity. OS played a pivotal role in the initial phase of AP, with significant changes in ROS and antioxidant defenses relating to AP severity. Phenylalanine (p < 0.05), threonine (p < 0.05), and lipids (p < 0.01) showed significant changes in AP severity. The role of hepcidin and SIRI were confirmed as new prognostic biomarkers of biliary AP. OS appears to have a role in the onset and progression of the AP process. Overall, this study identified several metabolites that may predict the onset and progression of biliary AP severity, constituting the first metabonomic study in the field of biliary AP.

Comparison of early and delayed cholecystectomy for biliary pancreatitis: A meta-analysis

BACKGROUND

Biliary stones are the most common etiology of acute pancreatitis Cholecystectomy has been accepted as a popular treatment for acute biliary pancreatitis (ABP) to reduce the risk of recurrent complications. However, the precise time of intervention still remains controversial.

OBJECTIVE

The aim of this meta-analysis was to compare early and delayed cholecystectomy and determine the most precise timing of cholecystectomy following gallstone pancreatitis.

METHOD

Search the publications on comparison the efficacy of early cholecystectomy comparison with delayed cholecystectomy in treatment outcomes of ABP to October, 2018. After rigorous reviewing on quality, the data was extracted from eligible trials. All trials analyzed the summary hazard ratios (HRs) of the endpoints of interest, including survival data and individual postoperative complications.

RESULTS

A total of 9 trials were met our inclusion criteria. The pooled results indicate that postoperative complications、readmission rate、conversion to an open procedure and cholecystectomy-related morbidity/mortality did not have statistical significance (P > 0.05) between the early and delayed cholecystectomy. While, the length of hospital stay was shorter for the early cholecystectomy group than the delayed group in all included studies.

CONCLUSIONS

Although the efficacy of delayed intervention in terms of inflammation reduction is definite, their adverse events are often major limitations. In the present study, an early cholecystectomy may result in a significantly shortened hospital stays without increased complications or mortality.

The safety, feasibility, and cost-effectiveness of early laparoscopic cholecystectomy for patients with mild acute biliary pancreatitis: A meta-analysis

BACKGROUND

It remains controversial on the optimal timing of cholecystectomy for patients with mild acute biliary pancreatitis. This study aimed at comparing the safety, feasibility, and cost-effectiveness of early laparoscopic cholecystectomy (ELC, within 72 h after admission) versus delayed laparoscopic cholecystectomy (DLC, beyond 72 h after admission) for patients with mild acute biliary pancreatitis.

METHODS

We performed a systematic search in the following databases: PubMed, Embase, Web of Science, and Cochrane library. We only included articles from RCTs which designed to evaluate the complications, conversion to open cholecystectomy, recurrence of acute pancreatitis, the length of hospital stay, and costs between patients undergoing ELC and those undergoing DLC. We schemed to analyze data using STATA 15.0 with both the random-effects and the fixed-effect models. We computed relative risk (RR) and weighted mean difference (WMD) with 95% confidence intervals (CI) based on the intention-to-treat (ITT) analysis.

RESULTS

A total of 4 studies involving 439 (215 vs 224) patients were included. The difference of complication rate [3.3% vs 3.2%; RR 1.03 (0.35, 3.01), P = 0.961] and rate of conversion to open cholecystectomy [3.8% vs 3.3%; RR 1.13 (0.37, 3.43), P = 0.830] are insignificant between patients who underwent ELC and ones who underwent DLC. The difference of rate of recurrence of acute pancreatitis is significant between ELC and DLC (2.17% vs 8.99%; RR 0.24 (0.08-0.70), P = 0.009). ELC does not shorten the length of hospital stay (random-effects model analysis: WMD -1.09 days (-2.67, 0.48), P = 0.173; fixed-effect model analysis: WMD -0.62 days (-1.00, -0.24), P = 0.001).

CONCLUSION

Compared to DLC, ELC is equally safe and feasible both in complication rate and rate of conversion to open procedure, and significantly reduces the recurrence rate of acute pancreatitis.

Evaluation of Prognostic Factors of Severity in Acute Biliary Pancreatitis

Acute pancreatitis (AP) is an inflammatory disorder of the pancreas that, when classified as severe, is associated with high morbidity and mortality. Promptly identifying the severity of AP is of extreme importance for improving clinical outcomes. The aim of this study was to compare the prognostic value of serological biomarkers, ratios, and multifactorial scores in patients with acute biliary pancreatitis and to identify the best predictors. In this observational and prospective study, the biomarkers, ratios and multifactorial scores were evaluated on admission and at 48 h of the symptom onset. On admission, regarding the AP severity, the white blood count (WBC) and neutrophil-lymphocyte ratio (NLR), and regarding the mortality, the WBC and the modified Marshall score (MMS) showed the best predictive values. At 48 h, regarding the AP severity, the hepcidin, NLR, systemic inflammatory response index (SIRI) and MMS and regarding the mortality, the NLR, hepcidin and the bedside index for severity in AP (BISAP) score, showed the best predictive values. The present study enabled the identification, for the first time, of SIRI as a new prognostic tool for AP severity, and validated hepcidin and the NLR as better prognostic markers than C-reactive protein (CRP) at 48 h of symptom onset.

The optimal timing of laparoscopic cholecystectomy in patients with mild gallstone pancreatitis: A meta-analysis

BACKGROUND

The optimal timing of laparoscopic cholecystectomy (LC) in patients with mild acute gallstone pancreatitis (MAGP) is controversial. The aim of this study was to systematically evaluate and compare the safety and efficacy of early laparoscopic cholecystectomy (ELC) and delayed laparoscopic cholecystectomy (DLC) in patients with MAGP.

METHODS

A strict search was conducted of the electronic databases, including PubMed, MEDLINE Embase, the ISI Web of Science, and Cochrane Library for all relevant English literature and RevMan5.3 software for statistical analysis was used.

RESULTS

A total of 19 studies comprising 2639 patients were included. There was no significant difference in intraoperative complications [risk ratio (RR) = 1.46; 95% confidence interval (CI) = 0.88-2.41; P = .14)], postoperative complications (RR = 0.81; 95% CI = 0.58-1.14; P = .23), rate of conversion to open cholecystectomy (RR = 1.00; 95% CI = 0.75-1.33; P = .99), operative time (MD = 1.60; 95% CI = -1.36-4.56; P = .29), and rate of readmission (RR = 0.63; 95% CI = 0.19-2.10; P = .45) between the ELC and DLC groups. However, the ELC group was significantly correlated with lower length of hospital stay (MD = -2.01; 95% CI = -3.15 to -0.87; P = .0006), fewer gallstone-related events rates (RR = 0.17; 95% CI = 0.07-0.44; P = .0003), and lower endoscopic retrograde cholangiopancreatography (ERCP) usage (RR = 0.83; 95% CI = 0.71-0.97; P = .02) compared with the DLC group.

CONCLUSION

Early laparoscopic cholecystectomy is safe and effective for patients with MAGP, but the indications and contraindications must be strictly controlled.

Patients' Perceptions of Experiences of Recovering From Acute Pancreatitis: An Interview Study

The incidence of registered admissions in inpatient care with a diagnosis of acute pancreatitis was 58 per 100,000 capita in Sweden during the year 2013. Although acute pancreatitis is a well-explored area, there is a demand for research from the patients' perceptions. The aim of this study was to describe patients' perceptions of recovering from acute pancreatitis. Data collection for this phenomenographical study included 16 individual semistructured interviews. Analysis was done according to the 7 steps suggested by . Recovery after acute pancreatitis was perceived within 5 categories; a time of physical suffering, an emotional journey, challenges to the usual life and its good qualities, barriers and need for social support, and healthcare as an important factor. Physical and emotional symptoms influence recovery after acute pancreatitis by challenging the good things and things that are taken for granted in everyday life. Promoting factors toward good recovery was a proper support from the social network as well as healthcare providers.

Systematic review of outcomes used to evaluate enhanced recovery after surgery

BACKGROUND

Enhanced recovery pathways (ERPs) aim to improve patient recovery. However, validated outcome measures to evaluate this complex process are lacking. The objective of this review was to identify how recovery is measured in ERP studies and to provide recommendations for the design of future studies.

METHODS

A systematic search of MEDLINE, Embase and Cochrane databases was conducted. Prospective studies evaluating ERPs compared with traditional care in abdominal surgery published between 2000 and 2013 were included. All reported outcomes were classified into categories: biological and physiological variables, symptom status, functional status, general health perceptions and quality of life (QoL). The phase of recovery measured was defined as baseline, intermediate (in hospital) and late (following discharge).

RESULTS

A total of 38 studies were included based on the systematic review criteria. Biological or physiological variables other than postoperative complications were reported in 30 studies, and included return of gastrointestinal function (25 studies), pulmonary function (5) and physical strength (3). Patient-reported symptoms, including pain (16 studies) and fatigue (9), were reported less commonly. Reporting of functional status outcomes, including mobilization (16 studies) and ability to perform activities of daily living (4), was similarly uncommon. Health aspects of QoL were reported in only seven studies. Length of follow-up was generally short, with 24 studies reporting outcomes within 30 days or less. All studies documented in-hospital outcomes (intermediate phase), but only 17 reported postdischarge outcomes (late phase) other than complications or readmission.

CONCLUSION

Patient-reported outcomes, particularly postdischarge functional status, were not commonly reported. Future studies of the effectiveness of ERPs should include validated, patient-reported outcomes to estimate better their impact on recovery, particularly after discharge from hospital.
