Gd-EOB-DTPA-Enhanced MRI for Detection of Liver Metastases from Colorectal Cancer: A Surgeon’s Perspective!

Colorectal cancer affects over one million people worldwide annually, with the liver being the most common site of metastatic spread. Adequate resection of hepatic metastases is the only chance for a cure in a subset of patients, and five-year survival increases to 35% with complete resection. Traditionally, computed tomographic imaging (CT) was utilized for staging and to evaluate metastases in the liver. Recently, the introduction of hepatobiliary contrast-enhanced magnetic resonance imaging (MRI) agents including gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Eovist in the United States, Primovist in Europe, or Gd-EOB-DTPA) has proved to be a sensitive method for detection of hepatic metastases. Accurate detection of liver metastases is critical for staging of colorectal cancer as well as preoperative planning

Intracystic Hemorrhage Complicating Polycystic Liver Disease in a 90-Year-Old Woman.

Nonparasitic hepatic cysts are common benign tumors that are often asymptomatic and incidentally discovered on imaging. Intracystic hemorrhage is a rare complication of hepatic cysts. We review the literature and discuss a case of intracystic hemorrhage in a 90-year-old woman with polycystic liver disease. The patient underwent cyst aspiration and percutaneous drain placement with subsequent resolution of symptoms. To our knowledge, we report the oldest patient to present with hemorrhage into a hepatic cyst. This case presents unique challenges in management, both because of the patient's age and because of her polycystic liver disease

Validation of Revised American Joint Committee on Cancer Staging for Gallbladder Cancer Based on a Single Institution Experience

Gallbladder cancer is a rare malignancy, which often goes undiagnosed until advanced stages of disease and is associated with poor prognosis. The only potentially curative treatment is surgical resection. This retrospective study aims to investigate the validity of the revised 7th edition American Joint Committee on Cancer staging criteria and determine prognostic factors. Forty-two patients with confirmed gallbladder cancer who underwent attempted curative resection from 1999 to 2012 at the University of California, Irvine Medical Center were reviewed. Survival probability was determined using the Kaplan-Meier method. Ten patients underwent laparoscopy, were deemed unresectable, and no further surgical intervention was performed. R0 surgical resection, which included radical portal lymphadenectomy, liver segment IVb/V resection, with or without bile duct resection, was performed in the remaining 32 patients. N2 nodes were resected if positive on frozen section. Overall survival probability for Stage I to II patients was 100 per cent. Overall survival probability for Stage III patients was 80 per cent (95% confidence interval [CI], 61 to 99%) and 39.3 per cent (95% CI, 28 to 78%) for Stage IV patients. This study demonstrates that 7th edition clinical stage, T stage, and liver involvement are statistically significant predictors of prognosis. These data also demonstrate a benefit to extended resection in patients even with Stage III and IV disease

Total pancreatectomy and islet autotransplantation: A decade nationwide analysis.

AimTo investigate outcomes and predictors of in-hospital morbidity and mortality after total pancreatectomy (TP) and islet autotransplantation.MethodsThe nationwide inpatient sample (NIS) database was used to identify patients who underwent TP and islet autotransplantation (IAT) between 2002-2012 in the United States. Variables of interest were inherent variables of NIS database which included demographic data (age, sex, and race), comorbidities (such as diabetes mellitus, hypertension, and deficiency anemia), and admission type (elective vs non-elective). The primary endpoints were mortality and postoperative complications according to the ICD-9 diagnosis codes which were reported as the second to 25(th) diagnosis of patients in the database. Risk adjusted analysis was performed to investigate morbidity predictors. Multivariate regression analysis was used to identify predictors of in-hospital morbidity.ResultsWe evaluated a total of 923 patients who underwent IAT after pancreatectomy during 2002-2012. Among them, there were 754 patients who had TP + IAT. The most common indication of surgery was chronic pancreatitis (86%) followed by acute pancreatitis (12%). The number of patients undergoing TP + IAT annually significantly increased during the 11 years of study from 53 cases in 2002 to 155 cases in 2012. Overall mortality and morbidity of patients were 0% and 57.8 %, respectively. Post-surgical hypoinsulinemia was reported in 42.3% of patients, indicating that 57.7% of patients were insulin independent during hospitalization. Predictors of in-hospital morbidity were obesity [adjusted odds ratio (AOR): 3.02, P = 0.01], fluid and electrolyte disorders (AOR: 2.71, P < 0.01), alcohol abuse (AOR: 2.63, P < 0.01), and weight loss (AOR: 2.43, P < 0.01).ConclusionTP + IAT is a safe procedure with no mortality, acceptable morbidity, and achieved high rate of early insulin independence. Obesity is the most significant predictor of in-hospital morbidity

Surgery for gallstone ileus: a nationwide comparison of trends and outcomes.

IntroductionGallstone ileus is a mechanical bowel obstruction caused by a biliary calculus originating from a bilioenteric fistula. Because of the limited number of reported cases, the optimal surgical method of treatment has been the subject of ongoing debate.MethodsA retrospective review of the Nationwide Inpatient Sample from 2004 to 2009 was performed for gallstone ileus cases treated surgically by enterotomy with stone extraction alone (ES), enterotomy and cholecystectomy with fistula closure (EF), bowel resection alone (BR), and bowel resection with fistula closure (BF). Patient demographics, hospital factors, comorbidities, and postoperative outcomes were reported. Multivariate analysis was performed comparing mortality, morbidity, length of stay, and total cost for the different procedure types.ResultsOf the estimated 3,452,536 cases of mechanical bowel obstruction from 2004 to 2009, 3268 (0.095%) were due to gallstone ileus-an incidence lower than previously reported. The majority of patients were elderly women (>70%). ES was the most commonly performed procedure (62% of patients) followed by EF (19% of cases). In 19%, a bowel resection was required. The most common complication was acute renal failure (30.44% of cases). In-hospital mortality was 6.67%. On multivariate analysis, EF and BR were independently associated with higher mortality than ES [(odds ratio [OR] = 2.86; confidence interval [CI]: 1.16-7.07) and (OR = 2.96; CI: 1.26-6.96) respectively]. BR was also associated with a higher complication rate, OR = 1.98 (CI: 1.13-3.46).ConclusionsGallstone ileus is a rare surgical disease affecting mainly the elderly female population. Mortality rates appear to be lower than previously reported in the literature. Enterotomy with stone extraction alone appears to be associated with better outcomes than more invasive techniques
