Approach to the Diagnostic Workup and Management of Small Bowel Lesions at a Tertiary Care Center
AbstractBackgroundSmall bowel lesions (SBL) are rare, representing diagnostic and management challenges. The purpose of this cross-sectional study was to evaluate diagnostic modalities used and management practices of patients with SBL at an advanced endoscopic referral center.MethodsWe analyzed patients undergoing surgical management for SBL from 2005 to 2015 at a single tertiary care center. Patients were stratified into gastrointestinal bleed/anemia (GIBA) or obstruction/pain (OP).ResultsOne hundred and twelve patients underwent surgery after presenting with either GIBA (n = 67) or OP (n = 45...

Health State Utility Values for Ileostomies and Colostomies: a Systematic Review and Meta-Analysis
ConclusionsFollowing stoma surgery, values placed on quality of life are similar to those obtained from patients with conditions such as asthma and allergies or individuals of similar age without chronic conditions. This confirms the findings of questionnaire-based studies, which report minimal long-term decrements to overall quality of life among stomates. (Source: Journal of Gastrointestinal Surgery)

Utility of Tumor Burden Score to Stratify Prognosis of Patients with Hepatocellular Cancer: Results of 4759 Cases from ITA.LI.CA Study Group
AbstractBackgroundDichotomous models like Milan Criteria represent the routinely used tools for predicting the outcome of patients with hepatocellular carcinoma (HCC). However, a paradigm shift from a dichotomous to continuous prognostic stratification should represent a good strategy for improving the prediction process. Recently, the tumor burden score (TBS) has been proposed for selecting patients with colorectal liver metastases. To date, TBS has not been validated in a large HCC population. The main objective of this study was to evaluate the prognostic power of TBS in an HCC population treated with different curative...

The Limitations of Standard Clinicopathologic Features to Accurately Risk-Stratify Prognosis after Resection of Intrahepatic Cholangiocarcinoma
AbstractBackgroundThe ability to provide accurate prognostic data after hepatectomy for intrahepatic cholangiocarcinoma (ICC) remains poor. We sought to develop and validate a nomogram to predict survival, as well as investigate the clinical implications of underestimating patients ’ risk of recurrence.MethodsPatients undergoing curative-intent resection of ICC between 1990 and 2015 at 14 major hepatobiliary centers were included. Variables significant on multivariable analysis were used to construct a nomogram to predict disease-free survival (DFS). The nomogram assigned a score to each variable included in the mode...

Impact of Preoperative Opioid Use After Emergency General Surgery
AbstractBackgroundPreoperative exposure to narcotics has recently been associated with poor outcomes after elective major surgery, but little is known as to how preoperative opioid use impacts outcomes after common, emergency general surgical procedures (EGS).MethodsA high-volume, single-center analysis was performed on patients who underwent EGS from 2012 to 2013. EGS was defined as the seven emergent operations that account for 80% of the national burden. Preoperative opioid use was defined as having an active opioid prescription within 7  days prior to surgery. Chronic opioid use was defined as having an opioid pre...

Hepatic Paragonimiasis Mimicking Hepatocellular Carcinoma
AbstractParagonimiasis is a parasitic lung infection caused by lung flukes of the genusParagonimus. Ectopic infection may occur but rarely involves the liver. Here, we report a case of hepatic paragonimiasis in a Chinese man who was initially suspected to have hepatocellular carcinoma. He had been previously diagnosed with chronic hepatitis B. No specific symptoms or abnormal blood test results were observed, except for a significant rise in serum alfa-fetoprotein. Magnetic resonance imaging revealed a 12-cm mass with inhomogeneous signal intensity at the left lobe of the liver. Laparoscopic left hemihepatectomy was perfor...

ConclusionsThe AAST EGS grade for acute pancreatitis demonstrates initial validity; patients with increasing AAST EGS grade demonstrated longer hospital and ICU stays, and increased rates of readmission. AAST EGS grades assigned using cross sectional imaging findings were comparable to other severity scoring systems. Further studies should determine the generalizability of the AAST system.Level of Evidence: IVStudy Type: Single institutional retrospective review (Source: Journal of Gastrointestinal Surgery)

AbstractMixed adenoneuroendocrine carcinoma rarely occurs in the gallbladder. Most cases of cholecystic mixed adenoneuroendocrine carcinoma have been reported from Asia, North American, and Europe; however, there is scarce literature available on this tumor in other populations. Here, we report a case of mixed adenoneuroendocrine carcinoma in a Melanoderm woman who was initially suspected to have gallbladder cancer. No specific symptoms or abnormal blood test results were observed preoperatively.

Benign Tumors of the Pancreas —Radical Surgery Versus Parenchyma-Sparing Local Resection—the Challenge Facing Surgeons
AbstractPancreaticoduodenectomy and left-sided pancreatectomy are the surgical treatment standards for tumors of the pancreas. Surgeons, who are requested to treat patients with benign tumors, using standard oncological resections, face the challenge of sacrificing pancreatic and extra-pancreatic tissue. Tumor enucleation, pancreatic middle segment resection and local, duodenum-preserving pancreatic head resections are surgical procedures increasingly used as alternative treatment modalities compared to classical pancreatic resections. Use of local resection procedures for cystic neoplasms and neuro-endocrine tumors of the...

AbstractSplenic artery pseudoaneurysm is an extremely rare entity, although it is the most frequent location of visceral pseudoaneurysms. Trauma or previous pancreatitis (where the proteolytic pancreatic enzymes lead to the formation of pseudoaneurysm, as a result of enzymatic injury to the splenic artery wall) (Amico and Alves in Pancreatology 14: 144 –145,2014) is the most frequent causes. A high degree of suspicion is required for the accurate diagnosis.
