Exocrine pancreatic insufficiency in distal pancreatectomy: incidence and risk factors.

BACKGROUND: Exocrine pancreatic insufficiency (EPI) is a known consequence of pancreatic resection; however, its incidence following distal pancreatectomy is not well defined. The aim of this study was to describe the prevalence of EPI in patients undergoing distal pancreatectomy and moreover identify risk factors for developing de-novo EPI after distal pancreatectomy. METHODS: A prospectively maintained institutional pancreatic resection database was interrogated to identify patients who underwent distal pancreatectomy from 2005 to 2015. Pre- and post-operative exocrine function, histopathology, demographics and volume of pancreas resected were analyzed. RESULTS: The cohort consisted of 324 patients, 22 (6.8%) presented with EPI pre-operatively. 38 (12.6%) patients developed new onset EPI requiring pancreatic enzyme replacement therapy. There was no relationship between patient demographics or diabetes status and requirement for pancreatic enzyme replacement therapy, and no significant effect of resection volume on the need for pancreatic enzyme replacement therapy post-operatively (p ≥ 0.05). Having an underlying obstructive pancreatic pathology (p = 0.002) or a presenting history of acute pancreatitis (p < 0.001) significantly predicted development of de-novo EPI. CONCLUSION: These results indicate that pre-existing EPI at time of surgery is not uncommon. Patients presenting for distal pancreatectomy should be assessed pre-operatively for the need for pancreatic enzyme replacement therapy.

Early experience with cap-assisted endoscopic pancreatic necrosectomy: A technique to enhance safe tissue extraction and decrease interventions.

Background and study aim Endoscopic treatment of walled-off pancreatic necrosis (WOPN) has been established as an alternative to operative intervention for well selected patients for many years. Patients and methods A retrospective database of patients who underwent cap-assisted endoscopic necrosectomy of symptomatic or infected WOPN using the assistance of a sterilized banding cap was constructed. All procedures were performed at a single center between January 2017 and June 2018. Results Eight patients met the inclusion criteria for this study. Contrast computed tomography scan was obtained between the initial percutaneous or trans-gastric access and initial necrosectomy. The WOPN had a median length of 9.5 cm (range 3.2 - 14) and width of 5.3 cm (range 2.8 - 11.6). Median duration of endoscopic debridement was 69 minutes (range 21 - 105). Four of six patients underwent a second debridement with a median duration of 95 minutes (range 16 - 108). No periprocedural adverse events occurred. Follow-up was at 6 months, and there were no additional endoscopic or percutaneous interventions for recurrent pancreatic fluid collections. Conclusion The technique of cap-assisted necrosectomy can allow for safe and efficient method of endoscopically treating WOPN.

The Value of Quick Sepsis-Related Organ Failure Assessment Scores in Patients With Acute Pancreatitis Who Present to Emergency Departments: A Three-Year Cohort Study.

BACKGROUND: Distinguishing sepsis from other inflammatory syndromes continues to be a clinical challenge. The goal of risk stratification tools is to differentiate sepsis from other conditions. We compare the ability of quick sepsis-related organ failure assessment (qSOFA) and systemic inflammatory responses syndrome (SIRS) scores to predict prolonged length of stay (LOS) among patients who presented to the emergency department and hospital ward with acute pancreatitis (AP). METHODS: We compiled a retrospective database of all adult patients hospitalized for AP during 2015 - 2018 at a single tertiary care center. Independent t-tests, Pearson's correlation and multiple regressions were performed with hospital LOS as the dependent variable, versus demographic characteristics and etiology of the pancreatitis as independent variables. Prolonged LOS was defined as > 5 days. RESULTS: The sensitivity and specificity of an SIRS score of 2 or greater for the detection of patients with prolonged LOS were 61% and 80%, respectively. The qSOFA score of 2 or greater corresponded to a diagnosis of significant AP with a specificity of 99% and a sensitivity of 4%. Multiple regression analysis demonstrated that each point increase in an SIRS score is associated with 2.24 days in additional hospital LOS. Interestingly, SIRS scores were found to correlate with the LOS, but not qSOFA. CONCLUSION: The qSOFA is a tool designed to identify patients at high risk of mortality due to sepsis. The data suggest that as with sepsis, patients with AP who are triaged with only qSOFA could be underrecognized and subsequently undertreated. Secondarily, the data suggest that SIRS scoring has the potential to promptly predict how long patients with AP will stay in the hospital.

Economical effect of lumen apposing metal stents for treating benign foregut strictures.

AIM: To evaluate the clinical and economical efficacy of lumen apposing metal stent (LAMS) in the treatment of benign foregut strictures. METHODS: A single center retrospective database of patients who underwent endoscopic treatment of benign foregut strictures between January 2014 and May 2017 was analyzed. A control group of non-stented patients who underwent three endoscopic dilations was compared to patients who underwent LAMS placement. Statistical tests performed included independent t-tests and five-parameter regression analysis. RESULTS: Nine hundred and ninety-eight foregut endoscopic dilations were performed between January 2014 and May 2017. 15 patients underwent endoscopic LAMS placement for treatment of benign foregut stricture. Thirty-six patients with recurrent benign foregut strictures underwent three or more endoscopic dilations without stent placement. The cost ratio of endoscopic dilation to LAMS (stent, placement and retrieval) is 5.77. Cost effective analysis demonstrated LAMS to be economical after three endoscopic dilation overall. LAMS was cost effective after two dilations in the Post-surgical stricture subgroup. CONCLUSION: Endoscopists should consider LAMS for the treatment of benign foregut strictures if symptoms persist past three endoscopic dilations. Post-surgical strictures may benefit from LAMS if symptoms persist after two dilations in a post-surgical. Early intervention with LAMS appears to be a clinically and economically viable option for durable symptomatic relief in patients with these strictures.

Sigmoid volvulus in a patient with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS): a rare occurrence.

Mitochondrial diseases are rare and devastating, with a wide spectrum of clinical presentations and systemic symptoms. The majority of the published literature focuses on the neuromuscular manifestations and genetic components of this mitochondrial cytopathy, however, cardiac, renal, endocrine and gastrointestinal manifestations may also be present. The authors report a case detailing a 56-year-old woman's final hospitalisation from the gastrointestinal sequelae of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) (Co Q10 deficiency variant). She presented with abdominal pain and distension associated with lactic acidosis, and was shown on imaging to have a colon perforation. This resulted in emergent surgery at which a necrotic colon secondary to a sigmoid colon was identified. Following four subsequent operations, and the development of multiorgan failure, care was eventually withdrawn. Practitioners of patients with MELAS should be cognisant of the rare but devastating gastrointestinal consequences of mitochondrial diseases.

Nonspecific Erysipelothrix rhusiopathiae Bacteremia in a Patient with Subclinical Alcoholic Liver Disease.

Erysipelothrix rhusiopathiae, a pleomorphic gram-positive bacillus, is found widely in nature or as a commensal pathogen. It infects domestic animals such as swine, which may be the major reservoir of the organism. E. rhusiopathiae is primarily an occupational illness; 89% of the cases are linked to high-risk epidemiological situations. Humans that are infected by this bacillus typically present with one or a combination of the following symptoms: localized skin lesion (erysipeloid), diffuse cutaneous eruptions with systemic symptoms, or bacteremia, which is often followed by endocarditis. We report a case of E. rhusiopathiae bacteremia that was present without severe clinical illness such as endocarditis, arthritis, or skin lesions. The patient was a 64-year-old male with a complicated past medical history including subclinical alcoholic liver disease. Penicillin-G therapy completely resolved the patients bacteremia. The case presented has exceptional clinical merit due to 2 key factors: the patient does not fit the occupational demographic typically affected by this bacterium, and the patient presented with subclinical septicemia, which has a high correlation with fatal endocarditis. This case brings a new prospective to E. rhusiopathiae bacteremia.
