Clinical, Biochemical, and Radiological Correlation in the Severity of Acute Pancreatitis: A Retrospective Study.

To analyze the etiologies and the varying clinical presentationsand to validate the clinical, biochemical, and radiological signs with severity and prognosis of acute pancreatitis. A retrospective study of 1316 patients diagnosed with acute pancreatitis in an industrial hospital inJamshedpur, Jharkhand, was conducted, and their clinicoradiological profiles, etiological factors, and outcomes were studied. A total of 1316 cases were enrolled, out of which maximum cases (411 [31.23%]) were from the age group of 30-44 years, and the mean and median age were 44.54 and47 years, respectively. A total of 731 (55.45%) patients had social habits (i.e., alcohol and smoking), and 585 (44.45%) patients did not have any social habits. Based on the etiology of acute pancreatitis (AP), the majority of cases were due to alcoholism (710 [53.95%]) followed by gallstone (343 [26.06%]) and idiopathicpancreatitis(217 [16.48%]). As per the severity of AP, most patients showed mild pancreatitis (937 [71.20%]) followed by moderate (312 [23.71%])and severe pancreatitis (67 [05.09%]). Mild and moderate pancreatitis patients were shown in 85 and 28 cases,respectively, suggestive of chronic pancreatitis after repeated episodes of AP. But severe pancreatitis shown in 19 cases had hypocalcemia + shock + multi-organ dysfunction syndrome (MODS). In mild, moderate, and severe AP, the mortality rateswere 19 (02.03%), 44 (14.10%), and 21 (31.34%), respectively. Overall, 1232 (93.62%) of AP cases recovered and were discharged in stable condition, but 84 (06.38%) cases expired. AP is a common cause of acute abdomen in patients presenting to the surgical emergency department. The management is mainly conservative with surgery limited to only a few selected cases, depending upon the severity of the disease.

Real-time prediction of organ failures in patients with acute pancreatitis using longitudinal irregular data

It is extremely important to identify patients with acute pancreatitis who are at high risk for developing persistent organ failures early in the course of the disease. Due to the irregularity of longitudinal data and the poor interpretability of complex models, many models used to identify acute pancreatitis patients with a high risk of organ failure tended to rely on simple statistical models and limited their application to the early stages of patient admission. With the success of recurrent neural networks in modeling longitudinal medical data and the development of interpretable algorithms, these problems can be well addressed. In this study, we developed a novel model named Multi-task and Time-aware Gated Recurrent Unit RNN (MT-GRU) to directly predict organ failure in patients with acute pancreatitis based on irregular medical EMR data. Our proposed end-to-end multi-task model achieved significantly better performance compared to two-stage models. In addition, our model not only provided an accurate early warning of organ failure for patients throughout their hospital stay, but also demonstrated individual and population-level important variables, allowing physicians to understand the scientific basis of the model for decision-making. By providing early warning of the risk of organ failure, our proposed model is expected to assist physicians in improving outcomes for patients with acute pancreatitis.

Monocytic HLA-DR Expression in Immune Responses of Acute Pancreatitis and COVID-19.

Acute pancreatitis is a common gastrointestinal disease with increasing incidence worldwide. COVID-19 is a potentially life-threatening contagious disease spread throughout the world, caused by severe acute respiratory syndrome coronavirus 2. More severe forms of both diseases exhibit commonalities with dysregulated immune responses resulting in amplified inflammation and susceptibility to infection. Human leucocyte antigen (HLA)-DR, expressed on antigen-presenting cells, acts as an indicator of immune function. Research advances have highlighted the predictive values of monocytic HLA-DR (mHLA-DR) expression for disease severity and infectious complications in both acute pancreatitis and COVID-19 patients. While the regulatory mechanism of altered mHLA-DR expression remains unclear, HLA-DR-/low monocytic myeloid-derived suppressor cells are potent drivers of immunosuppression and poor outcomes in these diseases. Future studies with mHLA-DR-guided enrollment or targeted immunotherapy are warranted in more severe cases of patients with acute pancreatitis and COVID-19.

Efficacy and safety of neostigmine on treating gastrointestinal dysmotility in severe acute pancreatitis patients: study protocol for a randomized controlled trial

BackgroundAcute pancreatitis is a serious threat to human health and gastrointestinal dysmotility is a common complication for acute pancreatitis patients, resulting in delayed feeding, oral feeding intolerance, paralytic ileus, and abdominal compartment syndrome. Currently, there are limited treatment for this complication.Neostigmine is known to increase gastrointestinal motility and has been used to treat gastrointestinal dysmotility after surgery. However, research in treating acute pancreatitis with neostigmine is currently limited.MethodsThis trial is a randomized, placebo-controlled, double-blinded, mono-centric trial that will test the hypothesis that neostigmine can improve gastrointestinal motility in patients with severe acute pancreatitis. Up to 56 patients will be randomized in this study receiving 0.5 mg/1 ml of neostigmine methylsulfate injection twice per day or 1 ml of saline injection twice per day. Defection time (aim 1), mortality and organ failure (aim 2), borborygmus, starting of enteral nutrition and intra-abdominal pressure (aim 3), and length of ICU and hospital stay (aim 4) will be assessed.DiscussionFindings from this study will provide data supporting the usage of neostigmine for treating severe acute pancreatitis patients with gastrointestinal dysmotility.Trial registrationThis study is registered on chictr.org.cn with the identifier as ChiCTR2200058305.

Effect of Aggressive Intravenous Fluid Resuscitation Versus Nonaggressive Fluid Resuscitation in the Treatment of Acute Pancreatitis: A Systematic Review and Meta-Analysis.

Despite the need for active fluid therapy, fluid management of most acute pancreatitis (AP) cases is still supportive. The aim of this review is to compare the effect of aggressive versus nonaggressive intravenous (IV) fluid resuscitation in the treatment of acute pancreatitis. A systematic search of medical databases, such as Medline, Google Scholar, Science Direct, Cochrane Central, was conducted for publication until April 2022. We included randomized controlled trials or cohort (prospective and retrospective) studies reporting the outcomes of AP in patients that were managed with aggressive and nonaggressive IV fluid resuscitation. The primary outcome of interest was in-hospital mortality. Fourteen trials involving 3423 acute pancreatitis patients were included in the review. We did not observe any differences in the risk of mortality, persistent organ failure, and systemic inflammatory response syndrome in both study groups. However, there was an increased risk of development of pancreatic necrosis, renal failure, and respiratory failure in the aggressive fluid therapy group compared with nonaggressive therapy. The funnel plot showed no publication bias. Aggressive fluid therapy did not improve mortality rates in acute AP patients and was associated with an increased risk of acute renal failure, and respiratory failure.

Long-term clinical outcomes of a fully covered self-expandable metal stent for refractory pancreatic strictures in symptomatic chronic pancreatitis: An 11-year follow-up study.

A fully covered self-expandable metal stent (FCSEMS) has recently been applied in the management of chronic pancreatitis patients with pancreatic strictures. However, related long-term effects remain unclear. This study aimed to evaluate the long-term outcomes of FCSEMS placement in chronic pancreatitis patients with refractory strictures. We retrospectively reviewed our database for patients undergoing FCSEMS placement for refractory pancreatic strictures between September 2008 and December 2010. The main outcomes were technical, radiological, and clinical success, as well as recurrence and adverse events. A total of 35 patients were included. Technical success was achieved in all patients. The median FCSEMS indwelling time was 3.2months (interquartile range [IQR], 3.0-4.9months). Radiological success was achieved in all patients (complete, n=2; partial, n=33). Clinical success was achieved in 29 patients (82.9%; complete analgesic cessation, n=19; analgesic reduction >50%, n=11). During the median follow-up of 136months, (IQR, 85.8-145.5months), eight patients (22.9%) experienced recurrence. The median interval from stent removal to recurrence was 24.9months (IQR, 11.3-30.3months). Biliary obstruction, an early adverse event, occurred in two patients (5.7%); the late adverse event stent-induced de novo stricture was observed in 17 patients (48.6%). Our findings suggest that an FCSEMS is effective for relieving refractory strictures in chronic pancreatitis. However, FCSEMSs were associated with stent-induced de novo strictures in nearly half of the patients. Prospective studies are required to further evaluate the long-term efficacy and safety of FCSEMSs in chronic pancreatitis.

Multicolor Biosensor for Trypsin Detection Based on the Regulation of the Peroxidase Activity of Bovine Serum Albumin-Coated Gold Nanoclusters and Etching of Gold Nanobipyramids.

The detection of trypsin is significantly important for both clinical diagnosis and disease treatment. In this study, an innovative multicolor sensor for trypsin detection has been established based on the regulation of the peroxidase activity of bovine serum albumin-coated gold nanoclusters (BSA-Au NCs) and efficient etching of gold nanobipyramids (Au NBPs). BSA-Au NCs have slight peroxidase enzyme activity and can catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) to generate TMB+, while trypsin can hydrolyze BSA ligands on the surface of BSA-Au NCs, thus exposing more catalytic active sites of BSA-Au NCs and resulting in the enhancement of the peroxidase activity of BSA-Au NCs, hence more TMB+ is generated. Under acidic conditions, TMB+ can etch Au NBPs efficiently, consequently affecting the aspect ratio of Au NBPs accompanied by the ultraviolet-visible (UV-vis) spectra blue shifting of the system. Furthermore, this also results in color variations that can be distinguished and recognized by naked eyes without any expensive and sophisticated instruments. This multicolor sensor has an available linear relationship with the logarithm of the trypsin concentration in the range of 0.1-100 μg/mL, and the detection limit is 0.045 μg/mL. The designed sensor has been used to detect the concentration of trypsin in human serum samples from healthy individuals and pancreatitis patients with satisfactory results.

Plasma renalase levels are associated with the development of acute pancreatitis

Background/objectivesSevere acute pancreatitis is associated with significant morbidity and mortality. Identifying factors that affect the risk of developing severe disease could influence management. Plasma levels of renalase, an anti-inflammatory secretory protein, dramatically decrease in a murine acute pancreatitis model. We assessed this response in hospitalized acute pancreatitis patients to determine if reduced plasma renalase levels occur in humans. MethodsPlasma samples were prospectively and sequentially collected from patients hospitalized for acute pancreatitis. Two forms of plasma renalase, native (no acid) and acidified, were measured by ELISA and RNLS levels were compared between healthy controls and patients with mild and severe disease (defined as APACHE-II score ≥7) using nonparametric statistical analysis. ResultsControl (33) and acute pancreatitis (mild, 230 (76.7%) and severe, 70 (23.3%) patients were studied. Acidified RNLS levels were lower in pancreatitis patients: Control: 10.1 μg/ml, Mild 5.1 μg/ml, Severe 6.0 μg/ml; p < 0.001. Native RNLS levels were increased in AP: Control: 0.4 μg/ml, Mild 0.9 μg g/ml, Severe 1.2 μg/ml p < 0.001; those with severe AP trended to have higher native RNLS levels than those with mild disease (p = 0.056). In patients with severe AP, higher APACHE-II scores at 24 h after admission correlated with lower acid-sensitive RNLS levels on admission (r = −0.31, p = 0.023). ConclusionLow plasma acidified RNLS levels, and increased native RNLS levels are associated with AP. Additional studies should assess the clinical correlation between plasma RNLS levels and AP severity and outcomes.

Distribution analysis of positive and negative pathogenic bacteria in patients with acute pancreatitis and the clinical characteristics and model prediction analysis of positive infection bacteria.

There were bacteria in the early pancreatic juice culture of severe acute pancreatitis (SAP) patients, but during the clinical time, some patients showed more positive bacteria and some patients showed more negative bacteria. Many scholars have different test results, and further clinical research needs to be carried out to clarify this fact. To determine evidence of infection in the early stage of acute pancreatitis (AP) by pancreatic juice bacterial culture and provide a reference for the anti-infective therapy of AP. Patients with AP who underwent pancreatic juice bacterial culture in the Department of hepatobiliary surgery of the General Hospital of Ningxia Medical University from January 1, 2019 to June 30, 2020were reviewed. Endoscopic retrograde cholangiopancreatography (ERCP) was used to collect pancreatic juice, which was sent to the laboratory for culturing. The clinical data and bacterial culture results of the patients were then recorded and analyzed. According to the results of the pancreatic juice culture, the patients were divided into a positive bacterial culture group (n=64) and a negative bacterial culture group (n=92). It was compared the data results of two groups [age, gender, etiology, acute physiology and chronic health evaluation (APACHE) II score, cultured bacteria, complications, local complications, Balthazar computed tomography (CT) score, inflammatory factors, the use of antibiotics, drug sensitivity analysis results, and the patient's co-infection] and performed multivariate analysis to identify the clinically valuable indicators. Moreover, a receiver operating characteristic (ROC) curve was drawn to predict the model of positive pancreatic juice culture in AP. The patients in the positive bacterial culture group and the negative bacterial culture group had statistically significant differences in gender, age, body mass index (BMI), amylase, white blood cell count and the two groups of patients were comparable. A total of 156 patients were included in the study and pathogenic bacteria were cultured in the pancreatic juice of 64 patients (41.03%) and 94 strains of bacteria were found (Gram-positive bacteria, 38.30%; Gram-negative bacteria, 58.51%; fungi, 3.19%). A history of ERCP and early pancreatic necrosis were independent influencing factors of positive pancreatic juice culture. The incidence of complications, APACHE II, and inflammatory factor levels of patients with positive pancreatic juice bacterial culture were significantly higher than those of negative pancreatic juice bacterial culture (P<0.05). Multivariate regression and the ROC curve of pancreatic infection showed that positive pancreatic and Balthazar CT score >7 on admission were independent risk factors of pancreatic. The area under the ROC curve of patients with later pancreatic infection was 0.863 [95% confidence interval (CI): 0.769-0.957], specificity was 65.30%, sensitivity was 90.50%, and the Youden index was 0.603. Bacterial culturing of pancreatic juice provides evidence of infection in the early stage of AP, which has certain significance for the anti-infective therapy of AP.

Association between early vasopressor administration and in-hospital mortality in critically ill patients with acute pancreatitis: A cohort study from the MIMIC-IV database.

This study aims to explore the association between early administration of vasopressors and in-hospital mortality in acute pancreatitis (AP) patients admitted to the ICU. The MIMIC-IV database was used to identify AP patients who had and had not received vasopressors. Univariate and multivariate logistic regression, propensity score matching (PSM), and inverse probability of treatment weighting (IPTW) were used for statistical analysis. A total of 894 AP patients admitted to the ICU were included in the study. Among them, AP patients who received vasopressors were associated with an increased risk of in-hospital mortality in the unadjusted model (OR: 7.77, 95% CI 4.92-12.61, p<0.001), multivariable-adjusted model (OR: 2.51,95% CI 1.1-5.76, p<0.05), PSM model (OR: 2.58, 95% CI 1.03-6.85, p<0.05) and IPTW model (OR: 1.82, 95% CI 1.06-3.15, p<0.05) compared with patients who did not receive vasopressors. In the subgroup analysis, age (≥ 65 years old: OR: 2.5, 95% CI 0.82-7.91; <65 years old: OR: 4.63, 95% CI 0.84-26.41), male (OR: 1.19, 95% CI 0.35-4.03), ethnicity (white: OR: 2.49, 95% CI 0.81-7.62; non-white: OR: 4.28, 95% CI 0.85-23.7), usage of norepinephrine (OR: 2.29, 95% CI 0.91-5.78), and single-use of vasopressor (OR: 1.48, 95% CI 0.43-4.95) were not associated with in-hospital mortality in patients with AP, whereas vasopressin (OR: 4.27, 95% CI 1.24-15.13; p<0.05) and phenylephrine usage (OR: 4.75, 95% CI 1.66-13.95; p<0.05), combined vasopressor usage (OR: 4.41, 95% CI 1.55-12.96; p<0.01), and female usage (OR: 7.89, 95% CI 2.03-34.2; p<0.01) were associated with in-hospital mortality. Early vasopressor use is significantly associated with increased in-hospital mortality among critically ill AP patients. This association might be greater in females, vasopressin, phenylephrine, and combined vasopressor users. Our results may benefit clinicians as they can guide the rational use of vasopressors in critically ill AP patients admitted to the ICU.

Evolution of Rosemont’s indeterminate for chronic pancreatitis in recurrent acute pancreatitis patients with 1-year follow-up: A prospective case series

Some patients presenting with recurrent acute pancreatitis (RAP), while undergoing endoscopic ultrasound (EUS), are classified as indeterminate for chronic pancreatitis (CP) according to Rosemont criteria. We are describing the clinical and radiological evolution of 14 such patients for 1 year. All the patients were closely followed up at 3 monthly intervals and subjected to ultrasound abdomen and blood sugar profile 6 monthly and EUS after 12 months. Males were 93%. Median age was 26 years. Most common etiology of RAP was idiopathic followed by ethanol and hypertriglyceridemia. On 1-year follow-up, 35.7% remained pain free and 28.6% had acute pancreatitis attack. Endocrine and exocrine insufficiency seen in one and two patients, respectively. Follow-up EUS in eight patients revealed Rosemont “normal” in 1, “Indeterminate” in 2, suggestive of CP in 3, and consistent with CP in two patients. Therefore, Rosemont’s “Indeterminate’’ progress to suggestive/consistent with CP in majority of patients.

Distal pancreatectomy for chronic pancreatitis: influence of obesity

Background: A relatively small percentage of chronic pancreatitis patients have disease localized to the tail of the pancreas. These patients benefit from distal pancreatectomy (DP); however, disease-related inflammation and vascular involvement complicate operation in this population. Few large studies have analyzed DP outcomes in chronic pancreatitis. We hypothesized that patient and disease-related features may predict outcome in DP for chronic pancreatitis.

Chronic Pancreatitis and Risk of Atherosclerotic Cardiovascular Disease: A US Cohort Propensity-Matched Study.

Worldwide prevalence of chronic pancreatitis (CP) has risen in recent years, with data suggesting an increased risk of atherosclerotic cardiovascular disease (ASCVD) in these patients. We assessed the incidence and risk of ASCVD in patients with CP. We compared the risk of ischemic heart disease, cerebrovascular accident, and peripheral arterial disease between CP and non-CP cohorts after propensity matching of known risk factors of ASCVD using TriNetX, a multi-institutional database. We also evaluated the risk of outcomes of ischemic heart disease including acute coronary syndrome, heart failure, cardiac arrest, and all-cause mortality between CP and non-CP cohorts. Chronic pancreatitis cohort was also found to have an increased risk of ischemic heart disease (adjusted odds ratio [aOR], 1.08; 95% confidence interval [CI], 1.03-1.12), cerebrovascular accident (aOR, 1.12; 95% CI, 1.05-1.20), and peripheral arterial disease (aOR, 1.17; 95% CI, 1.1-1.24). Chronic pancreatitis patients with ischemic heart disease were also found to have an increased risk of acute coronary syndrome (aOR, 1.16; 95% CI, 1.04-1.30), cardiac arrest (aOR, 1.24; 95% CI, 1.01-1.53), and mortality (aOR, 1.60; 95% CI, 1.45-1.77). Chronic pancreatitis patients are at a higher risk of ASCVD when compared with the general population, matched for confounding etiological, pharmacological, and comorbid variables.

The Potential Role of Model for End-Stage Liver Disease (MELD)-Sodium Score in Predicting the Severity of Acute Pancreatitis.

Background and aim Acute pancreatitis is a common inflammation of the pancreas which can be severe and even potentially mortal. High rates of mortality showed the importance of immediate identification of patients at high risk and led the clinicians to refer to various scoring systems. Our aim was to investigate a clinical predictive model using the Model for End-Stage Liver Disease-Sodium (MELD-sodium) scoring system, adapting it to acute pancreatitis patients referring to the systemic inflammatory nature of the disease and potential multi-organ failures in severe form. Methods Our multicenter study was designed retrospectively. The medical records were reviewed for the period of two years. Demographics, biochemical results, MELD-sodium scores and mortality rates were analysed. Results MELD-sodium score was found to be statistically correlated with both mortality and the severity of pancreatitis (p<0.001) and significant difference between both mild and severe (p<0.001), moderate and severe groups (p<0.001). Mortality was found to be significantly higher in patients with MELD-Na score when the cut-off value was accepted as '≥11'. Conclusion We found that MELD-sodium score was significantly associated with both severity of disease and mortality rates and also significantly effective between both mild/severe and moderate/severe groups which may be a guide for future multi-center reviews with larger patient and control groups, which can define the potential role of this non-invasive and easy-to-use predictive model in acute pancreatitis patients.

The effect of anemia on the severity and prognosis of patients with acute pancreatitis: A single-center retrospective study

Anemia was a risk factor for a worse prognosis of many diseases. This study aims to investigate the relationship between anemia and the severity and prognosis of acute pancreatitis (AP). Inpatients hospitalized at the First Affiliated Hospital of Guangdong Pharmaceutical University with a primary diagnosis of AP between 1st July 2016 to 31st December 2020 were enrolled. Subsequently, disease severity, the incidence of complications, and the prognosis of patients with AP were compared between the anemic group and the non-anemic group. A total of 282 patients with acute pancreatitis were enrolled; 68.43% of them were also diagnosed with anemia. Notably, these patients had more severe disease (higher RANSON, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, and multiple organ dysfunction syndrome scores); higher incidence of organ failure (acute kidney injury [AKI] and acute heart failure); worse prognosis (higher incidence of vasoactive and diuretic agent use, longer hospital stays, and higher hospital costs) compared to that of patients without anemia (all P < .05). After adjusting for potential confounders, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, multiple organ dysfunction syndrome scores, hospital stay, and hospital costs in anemic patients were higher than those in non-anemic patients; besides, the incidence of AKI and using a diuretic agent in anemic patients was 6.645 and 4.053 times that of non-anemic patients in AP, respectively (all P < .05). Acute pancreatitis patients with anemia have more disease severity, higher incidence of AKI, and worse prognosis compared to those without anemia.

İnsülin direncinin akut pankreatit şiddetine etkisi

Giriş ve Amaç: Akut pankreatit, pankreasın çeşitli nedenlere bağlı inflamasyonudur. Tüm dünyada önemli bir morbidite ve mortalite nedenidir. Metabolik sendromun önemli bir komponenti olan insülin direncinin inflamatuvar bir durum olması nedeniyle akut pankreatit hastalarında hastalık şiddetini etkileyebileceği düşünülmektedir. Çalışmamızda insülin direncinin akut pankreatit şiddeti ile ilişkisini araştırmayı ve diğer prognostik faktörlerle karşılaştırmayı amaçladık. Gereç ve Yöntem: Çalışmamızda klinikte akut pankreatit tanısı ile yatarak tedavi almış 84 hasta değerlendirmeye alınmıştır. Çalışmamız prospektif olarak dizayn edilmiştir. Akut pankreatit şiddetini belirlemek için hastaların laboratuvar ve görüntüleme bulguları kullanılarak Atlanta Sınıflandırması, 'Bedside Index of Severity in Acute Pancreatitis' skoru, Imrie skoru, Ranson skoru, Balthazar skoru belirlenmiştir. Hastalarda insülin direnci değerlendirilmesi için “İnsülin Direncinin Homeostatik Modeli Değerlendirmesi” skoru kullanılmıştır. Buna göre insülin direnci olan ve olmayan gruplar arasında hastalık şiddeti açısından fark olup olmadığı araştırılmıştır. Bulgular: Hastaların %45.2’si insülin direnci olan grupta yer aldı. Atlanta sınıflandırmasına göre 6 hasta (%7.1) şiddetli akut pankreatit olarak sınıflandırıldı. 4 hasta prerenal akut böbrek hasarı gelişmesi ve 2 hasta sepsis ve yoğun bakım gereksinimi olması nedeniyle şiddetli akut pankreatit olarak değerlendirildi. Hastalık şiddeti açısından yapılan Receiver Operating Characteristic analizinde Balthazar ve “Yatak başı akut pankreatit şiddet indeksi” skorunun hastaların prognozunu belirlemede güçlü oldukları görüldü (sırasıyla eğri altındaki alan; 0.955 ve 0.979). İnsülin direnci olan grubun “Yatak başı akut pankreatit şiddet indeksi” ve Balthazar skorları, insülin direnci olmayan grup ile karşılaştırıldığında istatistiksel olarak anlamlı farklılık saptandı (sırasıyla p = 0.019 ve p = 0.013). Sonuç: Çalışmamızda insülin direnci olan akut pankreatit hastalarında “Yatak başı akut pankreatit şiddet indeksi” ve Balthazar skorlarının yüksek saptanması, insülin direnci varlığının akut pankreatitin şiddetli seyretmesi yönünde prognostik bir faktör olarak kullanılabileceğini düşündürmektedir.

The Visceral-to-subcutaneous Adipose Tissue Area Ratio is Associated with Retreatment in Chronic Pancreatitis Patients with Pancreatolithiasis after Extracorporeal Shock Wave Lithotripsy.

Objective Extracorporeal shock wave lithotripsy (ESWL) has been used to treat pancreatolithiasis in patients with chronic pancreatitis (CP), but the high recurrence rate remains challenging. We therefore evaluated the association between body composition parameters and the prediction of retreatment after ESWL. Methods This study retrospectively evaluated 42 patients with CP who had been treated with ESWL between 2008 and 2019 in a single center. Body composition parameters were measured on pretreatment computed tomography images. Patients who underwent repeat ESWL were classified as the retreatment group. Results There were 13 (31.0%) and 29 (69.0%) patients in the retreatment and non-retreatment groups, respectively. The visceral-to-subcutaneous adipose tissue area ratio (VSR) of the retreatment group was significantly lower than that of the non-retreatment group (p=0.016). When divided by the median VSR, 10 of the 20 patients with a VSR of <0.85 underwent retreatment, whereas 3 of the 22 patients with a VSR of ≥0.85 underwent retreatment (p=0.019). According to a multivariate analysis, the VSR (p=0.010) and age (p=0.037) were independent factors associated with retreatment after ESWL. Conclusion This study showed that the VSR can predict the retreatment of patients with CP after ESWL.

Decreasing use of pancreatic necrosectomy and NSQIP predictors of complications and mortality

BackgroundSurgical pancreatic necrosectomy (SPN) is an option for the management of infected pancreatic necrosis. The literature indicates that an escalating, combined endoscopic, interventional radiology and minimally invasive surgery “step-up” approach, such as video-assisted retroperitoneal debridement, may reduce the number of required SPNs and ICU complications, such as multiple organ failure. We hypothesized that complications for surgically treated severe necrotizing pancreatitis patients decreased during the period of adoption of the “step-up” approach.MethodsThe American college of surgeons national surgery quality improvement program database (ACS-NSQIP) was used to find SPN cases from 2007 to 2019 in ACS-NSQIP submitting hospitals. Mortality and Clavien-Dindo class 4 (CD4) ICU complications were collected. Predictors of outcomes were identified by univariate and multivariate analyses.ResultsThere were 2457 SPN cases. SPN cases decreased from 0.09% in 2007 to 0.01% in 2019 of NSQIP operative cases (p < 0.001). Overall mortality was 8.5% and did not decrease with time. CD4 complications decreased from 40 to 27% (p < 0.001). There was a 65% reduction in SPN cases requiring a return to the operating room. Multivariate predictors of complications were emergency general surgery (EGS, p < 0.001), serum albumin (p < 0.0001) and modified frailty index (mFI) (p < 0.0001). Multivariate predictors of mortality were EGS (p < 0.0001), serum albumin (p < 0.0001), and mFI (p < 0.04). The mFI decreased after 2010 (p < 0.001).ConclusionSPNs decreased after 2010, with decreasing CD4 complications, decreasing reoperation rates and stable mortality rates, likely indicating broad adoption of a “step-up” approach. Larger, prospective studies to compare indications and outcomes for “step up” versus open SPN are warranted.

OGBN P19 Tackling a post-COVID-19 cholecystectomy waiting list, are we meeting the challenge?

Abstract Background The COVID-19 pandemic has led to a tremendous backlog in elective surgical activity, with over six million people on waiting lists and only 64% of patients meeting the 18-week elective standard. Our Hospital Trust adopted an innovative approach to dealing with elective waiting times for cholecystectomy during the recovery phase from COVID-19. This study aimed to evaluate trends in overall cholecystectomy activity and the effect on waiting times. Methods A prospective observational study was undertaken investigating patients who received a cholecystectomy at large UK hospital Trust, between February 2021 and February 2022. There were multiple phased strategies to tackle a 533 patient waiting list: private sector, multiple sites including emergency operating, mobile theatre, and seven-day working. An additional 364 patients were added and 145 removed, for multiple reasons, from the list during the study period. Correlation of determination (R2) and Kruskal-Wallis analysis were used to evaluate trends in waiting times across the study period. Results 657 patients underwent a procedure, of which 628 (95.6%) were completed electively. The median age was 49 years, 602 (91.6%) patients had an ASA of 1–2, and 494 (75.2%) were female. Thirty (4.6%) patients were listed post gallstone pancreatitis, 380 (57.8%) for cholelithiasis, and 228 (34.7%) for cholecystitis. The median length of stay was zero days (IQR 0–1), with 30-day complication (C-D ≥3, 1.8%), readmission (3.0%) and mortality (0.0%) rates noted. The current waiting list includes 95 patients, with median waiting times reduced from 428 days (IQR 373–508) to 49 (IQR 34–96), R2=0.654, p&amp;lt;0.001. For pancreatitis specifically, waiting times have dropped from a median of 218 days (IQR 139–239) to 28 (IQR 24–40), R2=0.613, p&amp;lt;0.001. Conclusions We have safely and effectively tackled the cholecystectomy waiting list locally utilising a number of phased strategies. Significant progress is being made towards once again meeting the gold-standard target for gallstone pancreatitis patients. The approach utilised here has potential to be adapted to other units, or other operation types in order to reduce elective waiting times.We have safely and effectively tackled the cholecystectomy waiting list locally utilising a number of phased strategies.
