RESUMO
BACKGROUND: Consequences of incidental gallbladder cancer (iGBC) following cholecystectomy may include repeat operation (depending on T stage) and worse survival (if bile spillage occurred), both avoidable if iGBC were suspected preoperatively. METHODS: A retrospective single-institution review was done. Ultrasound images for cases and controls were blindly reviewed by a radiologist. Chi-square and Student's t tests, as well as logistic regression and Kaplan-Meier analyses were used. A Pâ¯≤â¯0.01 was considered significant. RESULTS: Among 5796 cholecystectomies performed 2000-2013, 26 (0.45%) were iGBC cases. These patients were older (75.61 versus 52.27 years), had more laparoscopic-to-open conversions (23.1% versus 3.9%), underwent more imaging tests, had larger common bile duct diameter (7.13 versus 5.04â¯mm) and higher alkaline phosphatase. Ultrasound imaging showed that gallbladder wall thickening (GBWT) without pericholecystic fluid (PCCF), but not focal-versus-diffuse GBWT, was associated significantly with iGBC (73.9% versus 47.4%). On multivariable logistic regression analysis, GBWT without PCCF, and age were the strongest predictors of iGBC. The consequences iGBC depended significantly on intraoperative bile spillage, with nearly all such patients developing carcinomatosis and significantly worse survival. CONCLUSIONS: Besides age, GBWT, dilated common bile duct, and elevated alkaline phosphatase, number of preoperative imaging modalities and the presence of GBWT without PCCF are useful predictors of iGBC. Bile spillage causes poor survival in patients with iGBC.

BACKGROUND: Despite the increasing use of fatty meal (FM) as a substitute for cholecystokinin (CCK) in pain reproduction during hepato-imino-diacetic acid (HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application. METHODS: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results. RESULTS: Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction (61% vs 30%, P<0.01). CONCLUSIONS: Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder.

BACKGROUND: Cholecystectomy (CCY) is increasingly performed in older individuals. We sought to examine age-related differences in pre-, intra-, and postoperative factors at a community hospital, using a very large, single-institution cholecystectomy database. MATERIALS AND METHODS: A retrospective review of 6868 patients who underwent CCY from 2001 to 2013 was performed. ROC analysis identified the optimal age cutoff when complications reached a significant inflection point (<55 and ≥55 years). Multiple clinical features and outcomes were measured and compared by age. Logistic regression was used to examine how well a set of covariates predicted postoperative complications. RESULTS: Older patients had significantly higher rates of comorbidities and underwent more extensive preoperative imaging. Intraoperatively, older patients had more blood loss, longer operative times, and more open operations. Postoperatively, older patients experienced more complications and had significantly different pathological findings. While holding age and gender constant, regression analyses showed that preoperative creatinine level, blood loss and history of previous operation were the strongest predictors of complications. The risk for developing complications increased by 2% per year of life. CONCLUSION: Older patients have distinct pre-, intra-, and postoperative characteristics. Their care is more imaging- and cost-intensive. CCY in this population is associated with higher risks, likely due to a combination of comorbidities and age-related worsened physiological status. Pathologic findings are significantly different relative to younger patients. While removing the effect of age, preoperative creatinine levels, blood loss, and history of previous operation predict postoperative complications. Quantifying these differences may help to inform management decisions for older patients.

OBJECTIVE: To better understand important aspects of resident education in the perioperative setting, given that there are conflicting data regarding resident training and outcomes (e.g., operative times and complications). To study continuity of care in a resident-run outpatient hospital clinic. DESIGN: Retrospective analysis of 2 databases. SETTING: The study was set up in a community teaching hospital. RESULTS: Of 4603 cases in a cholecystectomy database, 3302 (72%) were assisted by residents, with operative times ranging from 19 to 383 minutes, and 1576 (22.9%) were assisted by nonresidents. The average times were 93 and 77 minutes for resident- and non-resident-assisted cases, respectively. Complications were almost 3 times more likely for urgent vs. elective but were similar for resident-assisted vs. non-resident-assisted cases. The operative time was similar across PGY levels. Of 149 cases in a resident-run outpatient clinic, 100 (67%) of the residents participated in preoperative, intraoperative, and postoperative phases of case, but in only 4% of cases was it the same resident. CONCLUSION: Resident assistance increased operative times but not complications. Counterbalanced effects of increasing skill and increasing participation may explain this time stability across PGY levels. Continuity of care is preserved in the era of the 80-hour workweek, but not to a patient-specific degree.

BACKGROUND: Perioperative blood transfusion (PBT) is common in pancreatic surgery. Recent studies have suggested that PBT may be associated with worse long-term outcomes. METHODS: A systematic review and meta-analysis of studies comparing long-term clinical outcomes of cancer patients undergoing curative-intent pancreatic surgery with regard to occurrence of PBT was performed. RESULTS: A total of 23 studies (4339 patients) were included in the systematic review, and 19 studies (3646 patients) were included in the meta-analysis. Nearly half (45.8 %) of all patients were female (range 25-60 %), and median age ranged from 59 to 72 years. About half (46.5 %, range 19-72 %) of the patients were transfused. Most had pancreatic ductal adenocarcinoma (69.5 %), while others had ampullary carcinoma (15.0 %), cholangiocarcinoma (7.4 %), or exocrine tumors of pancreas (8.1 %). Most (91.1 %) underwent pancreaticoduodenectomy, while the remaining patients underwent a total or distal pancreatectomy. The 5-year overall survival for all patients ranged from 0 to 65 %. Thirteen and nine of 19 studies reported a detrimental effect of PBT on survival on univariable and multivariable analysis, respectively. Overall, PBT was associated with shorter overall survival (pooled odds ratio 2.43, 95 % confidence interval 1.90-3.10); this finding was reproduced in sensitivity analysis. CONCLUSIONS: Patients receiving PBT had significantly lower 5-year survival after curative-intent pancreatic surgery. Further research should focus on implementing guidelines for and discerning factors associated with the poor outcomes after PBT.

BACKGROUND: Post-hepatectomy liver failure (PHLF) is a major source of morbidity and mortality in patients undergoing liver resection. The aim of this review is to summarize the recent literature available on PHLF including its definition, predictive factors, preoperative risk assessment, severity grading, preventative measures, and management strategies. METHODS: A systematic literature search was carried out with the search engines PubMed, Medline, and Cochrane Database using the keywords related to "liver failure", "posthepatectomy", and "hepatic resection". RESULTS: Liver resection is a curative treatment of liver tumors. However, it leads to concurrent death and regeneration of the remaining hepatocytes. Factors related to the patient, liver parenchyma and the extent of surgery can inhibit regeneration leading to PHLF. CONCLUSION: Given its resistance to treatment and the high postoperative mortality associated with PHLF, great effort has been put in to both accurately identify patients at high risk and to develop strategies that can help prevent its occurrence.

BACKGROUND: A large subset of patients with neuroendocrine liver metastasis (NELM) is symptomatic at the time of presentation. In addition to improving survival, treatment of NELM seeks to provide palliation of symptoms. However, data on health-related quality of life (QoL) are uncommon. We sought to define patient-reported QoL after treatment of NELM. METHODS: Patients who underwent treatment of NELM at Johns Hopkins Hospital between 1998 and 2013 and who were alive as of March 2014 were identified (n = 125). These patients were invited to complete a QoL survey designed using validated assessment tools, to assess their physical, mental, and general health before treatment, after the most recent treatment and at the time of the study. Clinicopathologic data were collected and correlated with QoL data. RESULTS: The response rate was 68.0% (n = 85). Median patient age was 55 y and most were male (59.2%). Most patients had a pancreatic (24.7%) or a small bowel (37.7%) primary tumor; the overwhelming majority had multiple NELM (83.5%). Patient-reported symptoms before any treatment included diarrhea (41.1%), flushing (34.1%), fatigue (36.5%), and osteoarticular pain (18.8%). Initial treatment of NELM consisted of surgery in 55 patients (64.7%) and nonsurgical treatment in 30 patients (35.3%). Many patients reported an overall improvement in physical health and mental health. Specifically, the proportion of patients reporting diarrhea (before any treatment, 41.1% versus currently, 25.9%; P = 0.019) and flushing (before any treatment, 34.1% versus currently, 10.5%; P < 0.001) tended to decrease over time and a lower proportion of patients reported to be currently sad about being ill (before any treatment, 31.8% versus currently, 23.2%; P = 0.009). Patients with a very poor QoL at the time of the diagnosis were more likely to experience an improvement in QoL after treatment. Interestingly, there was no difference in the improvement in overall QoL whether the initial treatment for NELM was surgical or nonsurgical; however, a lower proportion of patients were dissatisfied with surgery versus nonsurgical therapy (5.4% versus 9.4%; P = 0.001). CONCLUSIONS: Less than one-fourth of patients experienced a significant improvement in QoL after treatment of NELM. The patients who benefit the most of treatment were those who were more symptomatic before any treatment.

BACKGROUND: The objective of the current study was to define the incidence of 30-day readmission after hepatic resection for intrahepatic cholangiocarcinoma (ICC). In particular, we sought to identify risk factors associated with a higher risk of readmission among patients undergoing resection for ICC. METHODS: Patients who underwent hepatic resection for ICC at 12 major hepatobiliary centers in the USA, Europe, Australia, and Asia between 1990 and 2013 were identified. Thirty-day readmission and clinicopathologic characteristics associated with higher risk of readmission were examined. RESULTS: Among 602 patients, 401 (68.3%) patients underwent a major hepatectomy and 256 (43.3%) experienced at least one post-operative complication. Overall 30-day readmission was 7.8% (n = 47). Risk factors associated with readmission included pre-operative jaundice (odds ratio (OR) 2.45) and the presence of a major complication (OR 3.38). In fact, 95.7% of readmitted patients had experienced a post-operative complication versus only 38.8% of non-readmitted patients (P < 0.001). Among patients who were readmitted, repeat hospitalization was associated with a median LOS of 6.5 days (interquartile range (IQR) 4.0-11.5) and one patient died during readmission. CONCLUSIONS: Readmission after hepatic resection for ICC occurred in 1 in 13 patients. Patients with pre-operative jaundice and those who experienced a complication had over a threefold higher risk of being readmitted.
