RESUMO
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a dominant bariatric procedure. In the past, significant leak rates prompted the search for staple line reinforcement (SLR) techniques. Previous analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for all LSG suggested a detrimental influence of SLR on leak rates and overall morbidity. OBJECTIVE: To investigate the relationship between various SLR techniques and bougie size with 30-day outcomes. SETTING: Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited bariatric surgery hospitals. METHODS: Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 to 2016 Participant Use File data, primary LSG cases were divided into study groups based on surgical techniques. All variables were reported in the Participant Use File except leak rate and overall morbidity, which had to be derived. Multiple bivariate analyses were used to analyze the 30-day outcomes. RESULTS: A total of 198,339 primary LSG operations were included and grouped into No SLR (23.0%), SLR (54.2%), oversewn staple line (9.5%), and a combination of SLRâ¯+â¯oversewn staple line (13.3%). There were no statistical differences between study groups in mortality, overall morbidity, or leak rate. Bleeding and reoperation rates were statistically higher in the No SLR group. Bougie size was not associated with change in leak rates. CONCLUSION: Primary LSG is a safe procedure with low morbidity and mortality rates. SLR is associated with decreased rates of bleeding and reoperations but does not affect leak rates. The selection of SLR technique should be left to the surgeon's discretion with an understanding of the associated risks, benefits, and costs.

BACKGROUND: The clinical significance of cholesterolosis has not been well established but there are some provocative, if not robust, studies of the role it may play in the pathophysiology of pancreatitis and biliary dyskinesia, as well as hypercholesterolemia. Our aim was to take advantage of a very large cholecystectomy (CCY) database to support or refute these potentially important reported associations. MATERIALS AND METHODS: A retrospective review of 6868 patients who underwent CCY from 2001-2013 was performed. Comparisons were made using the student t-test for continuous and chi-square analysis for categorical, variables. RESULTS: Among patients for whom the CCY was the primary operation, 1053 (18%) had cholesterolosis and 4596 did not. Compared to those without cholesterolosis, those with cholesterolosis were no more likely to have elevated cholesterol levels (P = 0.64) nor low gallbladder ejection fraction (P = 0.2). To evaluate cholesterolosis as a cause of pancreatitis, all patients with gallstones were eliminated, leaving 639 patients. Among these, not only was cholesterolosis not associated with more pancreatitis, but rather there was not a single patient with or without cholesterolosis who had pancreatitis. CONCLUSIONS: Despite prior reports of associations between cholesterolosis and elevated serum cholesterol, depressed ejection fraction, and increased risk of pancreatitis, careful analysis of this current, larger data set does not support these associations. Any patient with stones or sludge, or with biliary dyskinesia, and appropriate symptoms, should be considered for CCY, with or without suspected cholesterolosis.

AIM: To investigate and summarize the literature regarding the diagnosis and management of intrahepatic pancreatic pseudocysts (IHPP). METHODS: A literature search was performed using PubMed (MEDLINE) and Google Scholar databases, followed by a manual review of reference lists to ensure that no articles were missed. All articles, case reports, systematic reviews, letters to editors, and abstracts were analyzed and tabulated. Bivariate analyses were performed, with significance accepted at P < 0.05. Articles included were primarily in the English language, and articles in other languages were reviewed with native speakers or, if none available, were translated with electronic software when possible. RESULTS: We found 41 published articles describing 54 cases since the 1970s, with a fairly steady rate of publication. Patients were predominantly male, with a mean age of 49 years. In 42% of published cases, the IHPP was the only reported pseudocyst, but 58% also had concurrent pseudocysts in other extrapancreatic locations. Average IHPP size was 9.5 cm and they occurred most commonly (48%) in the left hemiliver. Nearly every reported case was managed with an intervention, most with a single intervention, but some required up to three interventions. Percutaneous treatment with either simple aspiration or with an indwelling drain were the most common interventions, frequently performed along with stenting of the pancreatic duct. The size of the IHPP correlated significantly with both the duration of treatment (P = 0.006) and with the number of interventions required (P = 0.031). The duration of therapy also correlated with the initial white blood cell (WBC) count (P = 0.048). CONCLUSION: Diagnosis of IHPP is difficult and often missed. Initial size and WBC are predictive of the treatment required. With appropriate intervention, most patients achieve resolution.
