Toxic megacolon (TM) is a potentially fatal condition characterized by non-obstructive colonic dilatation and systemic toxicity. It is most commonly caused by inflammatory bowel disease (IBD). Limited data for TM are available demonstrating incidence, in-hospital outcomes and predictors of mortality. We sought to investigate incidence, characteristics, mortality and predictors of mortality associated with it. Data were obtained from the Healthcare Cost and Utilization Project (HCUP)'s Nationwide Inpatient Sample (NIS) database from January 2010 through December 2014. An analysis was performed on SAS 9.4 (SAS Institute Inc., Cary, NC). Patients below 18 years were excluded. A mixed-effects logistic regression model was developed to analyze predictors of mortality. Thus, 8139 (weighted) cases of TM were diagnosed between 2010 and 2014. TM is more prevalent in women (56.4%) than in men (43.6%), with a mean age of onset at 62.4 years, affecting whites (79.7%) more than non-whites. The most common reason for hospital admission included IBD (51.6%) followed by septicemia (10.2%) and intestinal infections (4.1%). Mean length of stay was 9.5 days and overall in-hospital mortality was 7.9%. Other complications included surgical resection of the large intestine (11.5%) and bowel obstruction (10.9%). Higher age, neurological disorder, coagulopathy, chronic pulmonary disease, heart failure, and renal failure were associated with greater risk of in-hospital mortality. TM is a serious condition with high in-hospital mortality. Management of TM requires an inter-disciplinary team approach with close monitoring. Patients with positive predictors in our study require special attention to prevent excessive in-hospital mortality.

Background/Aims: To analyze the incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) sepsis in the early (July to September) and later (October to June) academic months to assess the "July effect". Methods: The National Inpatient Sample (2010-2014) was used to identify ERCP-related adult hospitalizations at urban teaching hospitals by applying relevant procedure codes from the International Classification of Diseases, 9th revision, Clinical Modification. Post-ERCP outcomes were compared between the early and later academic months. A multivariate analysis was performed to evaluate the odds of post-ERCP sepsis and its predictors. Results: Of 481,193 ERCP procedures carried out at urban teaching hospitals, 124,934 were performed during the early academic months. The demographics were comparable for ERCP procedures performed during the early and later academic months. A higher incidence (9.4% vs. 8.8%, p<0.001) and odds (odds ratio [OR], 1.07) of post-ERCP sepsis were observed in ERCP performed during the early academic months. The in-hospital mortality rate (7% vs. 7.5%, p=0.072), length of stay, and total hospital charges in patients with post-ERCP sepsis were also equivalent between the 2 time points. Pre-ERCP cholangitis (OR, 3.20) and post-ERCP complications such as cholangitis (OR, 6.27), perforation (OR, 3.93), and hemorrhage (OR, 1.42) were significant predictors of higher post-ERCP sepsis in procedures performed during the early academic months. Conclusions: The July effect was present in the incidence of post-ERCP sepsis, and academic programs should take into consideration the predictors of post-ERCP sepsis to lower health-care burden.

This study concluded up to a 24% increased likelihood of pancreatic cancer among the HepB patients. Blacks showed greater odds of pancreatic cancer and related mortality.

Background: Evaluating patients who have sustained blunt abdominal trauma (BAT) remains one of the most challenging and resourceintensive aspects of acute trauma care. Missed intra-abdominal injuries continue to cause preventable deaths. Aims & Objective: To assess efficacy of CT scan (computed tomography) as accurate diagnostic tool for blunt abdominal trauma patients. Materials and Methods: 87 cases of blunt abdominal injury admitted in S.S.G hospital, Baroda during the period of August 2010 to November 2012 were included in the study after taking written informed consent. All these patients were thoroughly investigated. CT Scan was done for all hemodynamically stable patients. Recorded data included age, sex, type of injuries and scan results. Organ injuries were graded using the OIS (Organ Injury Scale) guidelines. Results: The study comprised of 87 patients having blunt abdominal injury. Majority of the patients were in the age group of 20-29 years. Most common organ injury were splenic (43%), liver (32%) and renal (11%). 95% (83 patients) were positive for abdominal injury and 5% (4 patients) were negative. The CT findings of hemoperitoneum and/or solid organ injury were confirmed in the 15 cases taken up for surgery. Conclusion: In this study CT scan was 100 % sensitive in diagnosis of blunt abdominal trauma. Negative CT scan discourage unnecessary urgent abdominal exploration.

Sinistral portal hypertension (SPH), also known as left-sided portal hypertension or segmental portal hypertension, is a rare cause of upper gastrointestinal bleeding. Historically, SPH is a result of obstruction of the splenic vein often secondary to pancreatic pathology. To our knowledge, there are no reported cases of idiopathic SPH in which the findings cannot be attributed to any etiology. It is important to do a detailed workup to rule out common pathologies of SPH before making a diagnosis of idiopathic SPH. Treatment of gastric variceal bleed secondary to idiopathic SPH can be challenging and requires a multidisciplinary approach with surgery and interventional radiology. Our patient's history, examination findings, and imaging revealed no identifiable cause for SPH suggesting idiopathic SPH. We describe a case of isolated gastric variceal hemorrhage due to idiopathic SPH that was successfully treated.
