RESUMEN

Bouveret's syndrome is a rare form of gallstone ileus described as a gastric outlet obstruction from a gallstone that travels from the gallbladder to the bowel through a bilioenteric fistula. Despite its rarity, the mortality rate of this condition is high. Endoscopic treatment is preferred over surgery due to the association with lower mortality rate. To date, there are limited data about the application of holmium:yttrium-aluminum-garnet (YAG) laser lithotripsy for fragmentation of gallstones in Bouveret's syndrome. We present the case of a 74-year-old man with multiple cardiac comorbidities who presented with periumbilical pain, decreased appetite, and vomiting. The patient had previously been admitted three months prior with acute cholecystitis, and a cholecystostomy tube was placed. He had leukocytosis and purulent discharge in his cholecystostomy bag. Computed tomography (CT) scan of the abdomen and pelvis showed a change in the position of a previously seen large gallstone from the neck of the gallbladder on the last admission, to the lumen of the duodenal bulb on this admission. This indicated the development of a cholecystoduodenal fistula, with the stone passing through this fistula into the duodenal bulb, causing the complete obstruction. Endoscopic treatment was recommended by the surgery team due to cardiac comorbidities and the significant friability of the tissue requiring laparotomy. Initial endoscopic evaluation showed complete obstruction of the duodenal bulb by a large smooth stone, not allowing passage of a guidewire beyond the stone. Therefore, holmium:YAG laser lithotripsy was used. After two sessions of laser therapy, four days apart, each breaking a pigmented and calcified stone, it eventually passed through the small bowel into the colon, relieving the obstruction. The patient had a favorable outcome and did not require surgery. This case report shows that holmium:YAG laser lithotripsy is capable of delivering favorable outcomes, as seen in a patient with a heavily calcified and pigmented stone, older age, and multiple comorbidities. Holmium:YAG laser could be considered for use with endoscopic equipment for future management of this condition, especially in patients who have medical comorbidities and heavily calcified gallstones.

RESUMEN

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.

RESUMEN

Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

RESUMEN

The necessity of routine endoscopic retrograde cholangiopancreatography (ERCP) after positive intraoperative cholangiogram (IOC) during laparoscopic cholecystectomy is not well defined. We aimed to examine the incidence of positive IOC among patients who undergo IOC during cholecystectomy and the rate of subsequent ERCP stone extraction. The Nationwide Inpatient Sample database was reviewed for all patients undergoing cholecystectomy with IOC from 2002 to 2012. Patients were then analyzed for ERCP and stone extraction. A total of 73,508 patients who underwent cholecystectomy with IOC for a diagnosis of acute cholecystitis and found to have a bile duct stone were identified. Of these patients, 5915 underwent subsequent ERCP. In the patients that underwent subsequent ERCP, 1478 had a documented stone extraction during ERCP. The rate of stone extraction in the ERCP subset is 25 per cent, which is 2 per cent of all patients who had a positive IOC. The rate of stone extraction after positive IOC is low. Positive IOC may not warrant a routine postoperative ERCP. Our results suggest that clinical monitoring of patients with positive IOC is reasonable, as the majority of patients with a positive IOC ultimately have no stone extraction.

RESUMEN

IMPORTANCE: The degree to which patients are empowered by written educational materials depends on the text's readability level and the accuracy of the information provided. The association of a website's affiliation or focus on treatment modality with its readability and accuracy has yet to be thoroughly elucidated. OBJECTIVE: To compare the readability and accuracy of patient-oriented online resources for pancreatic cancer by treatment modality and website affiliation. DESIGN: An online search of 50 websites discussing 5 pancreatic cancer treatment modalities (alternative therapy, chemotherapy, clinical trials, radiation therapy, and surgery) was conducted. The website's affiliation was identified. Readability was measured by 9 standardized tests, and accuracy was assessed by an expert panel. MAIN OUTCOMES AND MEASURES: Nine standardized tests were used to compute the median readability level of each website. The median readability scores were compared among treatment modality and affiliation categories. Accuracy was determined by an expert panel consisting of 2 medical specialists and 2 surgical specialists. The 4 raters independently evaluated all websites belonging to the 5 treatment modalities (a score of 1 indicates that <25% of the information is accurate, a score of 2 indicates that 26%-50% of the information is accurate, a score of 3 indicates that 51%-75% of the information is accurate, a score of 4 indicates that 76%-99% of the information is accurate, and a score of 5 indicates that 100% of the information is accurate). RESULTS: The 50 evaluated websites differed in readability and accuracy based on the focus of the treatment modality and the website's affiliation. Websites discussing surgery (with a median readability level of 13.7 and an interquartile range [IQR] of 11.9-15.6) were easier to read than those discussing radiotherapy (median readability level, 15.2 [IQR, 13.0-17.0]) (P = .003) and clinical trials (median readability level, 15.2 [IQR, 12.8-17.0]) (P = .002). Websites of nonprofit organizations (median readability level, 12.9 [IQR, 11.2-15.0]) were easier to read than media (median readability level, 16.0 [IQR, 13.4-17.0]) (P < .001) and academic (median readability level, 14.8 [IQR, 12.9-17.0]) (P < .001) websites. Privately owned websites (median readability level, 14.0 [IQR, 12.1-16.1]) were easier to read than media websites (P = .001). Among treatment modalities, alternative therapy websites exhibited the lowest accuracy scores (median accuracy score, 2 [IQR, 1-4]) (P < .001). Nonprofit (median accuracy score, 4 [IQR, 4-5]), government (median accuracy score, 5 [IQR, 4-5]), and academic (median accuracy score, 4 [IQR, 3.5-5]) websites were more accurate than privately owned (median accuracy score, 3.5 [IQR, 1.5-4]) and media (median accuracy score, 4 [IQR, 2-4]) websites (P < .004). Websites with higher accuracy were more difficult to read than websites with lower accuracy. CONCLUSIONS AND RELEVANCE: Online information on pancreatic cancer overestimates the reading ability of the overall population and lacks accurate information about alternative therapy. In the absence of quality control on the Internet, physicians should provide guidance to patients in the selection of online resources with readable and accurate information.

RESUMEN

AIM: To investigate outcomes and predictors of in-hospital morbidity and mortality after total pancreatectomy (TP) and islet autotransplantation. METHODS: The 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. RESULTS: We 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). CONCLUSION: TP + 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.

RESUMEN

INTRODUCTION: Perioperative goal-directed therapy (PGDT) may improve postoperative outcome in high-risk surgery patients but its adoption has been slow. In 2012, we initiated a performance improvement (PI) project focusing on the implementation of PGDT during high-risk abdominal surgeries. The objective of the present study was to evaluate the effectiveness of this intervention. METHODS: This is a historical prospective quality improvement study. The goal of this initiative was to standardize the way fluid management and hemodynamic optimization are conducted during high-risk abdominal surgery in the Departments of Anesthesiology and Surgery at the University of California Irvine. For fluid management, the protocol consisted in standardized baseline crystalloid administration of 3 ml/kg/hour and any additional boluses based on PGDT. The impact of the intervention was assessed on the length of stay in the hospital (LOS) and post-operative complications (NSQIP database). RESULTS: In the 1 year pre- and post-implementation periods, 128 and 202 patients were included. The average volume of fluid administered during the case was 9.9 (7.1-13.0) ml/kg/hour in the pre-implementation period and 6.6 (4.7-9.5) ml/kg/hour in the post-implementation period (p < 0.01). LOS decreased from 10 (6-16) days to 7 (5-11) days (p = 0.0001). Based on the multiple linear regression analysis, the estimated coefficient for intervention was 0.203 (SE = 0.054, p = 0.0002) indicating that, with the other conditions being held the same, introducing intervention reduced LOS by 18% (95% confidence interval 9-27%). The incidence of NSQIP complications decreased from 39% to 25% (p = 0.04). CONCLUSION: These results suggest that the implementation of a PI program focusing on the implementation of PGDT can transform fluid administration patterns and improve postoperative outcome in patients undergoing high-risk abdominal surgeries.

RESUMEN

Magnetic resonance imaging (MRI) is currently the modality of choice to evaluate liver lesions in patients with cirrhosis and hepatitis B and C. Hepatocellular carcinoma demonstrates typical imaging findings on contrast-enhanced MRI, which are usually diagnostic. Unfortunately, a subgroup of hepatocellular carcinoma presents with atypical imaging features, and awareness of these atypical presentations is important in ensuring early diagnosis and optimal patient outcomes. Herein, we review some of the more common atypical presentations with a focus on MRI.

RESUMEN

INTRODUCTION: Goal-directed fluid therapy strategies have been shown to benefit moderate- to high-risk surgery patients. Despite this, these strategies are often not implemented. The aim of this study was to assess a closed-loop fluid administration system in a surgical cohort and compare the results with those for matched patients who received manual management. Our hypothesis was that the patients receiving closed-loop assistance would spend more time in a preload-independent state, defined as percentage of case time with stroke volume variation less than or equal to 12%. METHODS: Patients eligible for the study were all those over 18 years of age scheduled for hepatobiliary, pancreatic or splenic surgery and expected to receive intravascular arterial blood pressure monitoring as part of their anesthetic care. The closed-loop resuscitation target was selected by the primary anesthesia team, and the system was responsible for implementation of goal-directed fluid therapy during surgery. Following completion of enrollment, each study patient was matched to a non-closed-loop assisted case performed during the same time period using a propensity match to reduce bias. RESULTS: A total of 40 patients were enrolled, 5 were ultimately excluded and 25 matched pairs were selected from among the remaining 35 patients within the predefined caliper distance. There was no significant difference in fluid administration between groups. The closed-loop group spent a significantly higher portion of case time in a preload-independent state (95 ± 6% of case time versus 87 ± 14%, P =0.008). There was no difference in case mean or final stroke volume index (45 ± 10 versus 43 ± 9 and 45 ± 11 versus 42 ± 11, respectively) or mean arterial pressure (79 ± 8 versus 83 ± 9). Case end heart rate was significantly lower in the closed-loop assisted group (77 ± 10 versus 88 ± 13, P =0.003). CONCLUSION: In this case-control study with propensity matching, clinician use of closed-loop assistance resulted in a greater portion of case time spent in a preload-independent state throughout surgery compared with manual delivery of goal-directed fluid therapy.

RESUMEN

OBJECTIVE: Previous studies have proved the feasibility of performing a pancreaticoduodenectomy (Whipple operation) in patients with portal vein-superior mesenteric vein and hepatic artery invasion. We report our institutional experience with the use of a variety of vascular reconstructive methods during pancreatic resections for adenocarcinoma. METHODS: A retrospective review was performed identifying all patients undergoing a Whipple operation or total pancreatectomy procedure from January 2003 to December 2013. All venous (portal vein-superior mesenteric vein) and arterial (superior mesenteric artery-hepatic artery) reconstructions were extracted and reviewed to determine survival and perioperative complications. RESULTS: During the 10-year study period, 270 Whipple and total pancreatectomy procedures were performed, of which 183 were for adenocarcinoma of the pancreas. Of the 183 operations, a total of 60 (32.8%) vascular reconstructions were found, 49 venous and 11 arterial. Venous reconstruction included 37 (61.7%) primary repairs, four (6.7%) reconstructions with CryoVein (CryoLife, Inc, Kennesaw, Ga), three (5.0%) repairs with autologous vein patch, three (5.0%) autologous saphenous reconstructions, and two (3.33%) portacaval shunts. In addition, there were 11 (18.3%) arterial reconstructions (seven hepatic artery and four superior mesenteric artery). The 1-year survival for all reconstructions was 71.1%, which is equivalent to T3 lesions that did not receive vascular reconstruction (70.11%), with a median survival time of 575.28 days and 12 patients still alive. Survival time was comparable with each type of venous reconstruction, averaging 528 days (11 of 49 patients still alive). There was a total thrombosis rate of seven of 60 (11.6%), all of which were portal vein thrombosis: three in the primary repair group and four delayed thromboses seen in primary repair, CryoVein repair, and vein patch repair. There was no thrombosis in any patients after arterial reconstruction. CONCLUSIONS: An aggressive approach for stage II pancreatic cancers with venous or arterial invasion can be performed with comparable results when it is executed by an experienced institution with skilled oncologic and vascular surgeons.

RESUMEN

Hepatocellular carcinoma (HCC) is the most common histologic type of primary liver cancer, accounting for between 85% and 90% of these malignancies. The overall prognosis of patients with liver cancer is poor, and an understanding of this disease and its risk factors is crucial for screening at-risk individuals, early recognition, and timely diagnosis. Most HCCs arise in the background of chronic liver disease caused by hepatitis B virus, hepatitis C virus, and chronic excessive alcohol intake. These underlying causes are characterized by marked variations in geography, gender, and other well-documented risk factors, some of which are potentially preventable.

RESUMEN

Bi-phenotypic neoplasm refers to tumors derived from a common cancer stem cell with unique capability to differentiate histologically into two distinct tumor types. Bi-phenotypic hepatocellular carcinoma-cholangiocarcinoma (HCC-CC), although a rare tumor, is important for clinicians to recognize, since treatment options targeting both elements of the tumor are crucial. Imaging findings of bi-phenotypic HCC-CC are not specific and include features of both HCC and CC. A combination of imaging and immuno-histochemical analysis is usually needed to make the diagnosis.

RESUMEN

General surgery has become increasingly fragmented into subspecialties and diseases previously treated by general surgeons are now managed by "specialists". The Resident Education Committee of the Society for Surgery of the Alimentary Tract (SSAT) has reviewed the history of surgical training and factors that have contributed to this evolution to subsepcialization. As it is unlikely that this paradigm shift is reversible, a clear understanding of the contributing factors is essential. Herein, we present a timeline and taxonomy of forces in this evolution to subspecialization.

RESUMEN

INTRODUCTION: Gallstone 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. METHODS: A 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. RESULTS: Of 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). CONCLUSIONS: Gallstone 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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Data on infiltrating hepatocellular carcinoma (HCC) are limited. We sought to define treatment and outcome of patients treated with infiltrating HCC compared with patients who had advanced multifocal HCC. METHODS: Between January 2000 and July 2011, a total of 147 patients with advanced HCC were identified from the Johns Hopkins Hospital database (infiltrative, n = 75; multifocal, n = 72). Clinicopathologic data were compared by HCC subtype. RESULTS: Patients with infiltrating HCC had higher alfa-fetoprotein levels (median infiltrative, 326.5 ng/mL vs. multifocal, 27.0 ng/mL) and larger tumors (median size, infiltrating, 9.2 cm vs. multifocal, 5.5 cm) (P < 0.05). Imaging failed to reveal a discrete lesion in 42.7 % of patients with infiltrating HCC. Most infiltrating HCC lesions presented as hypointense on T1-weighted images (55.7 %) and hyperintense on T2-weighted images (80.3 %). Among patients with infiltrating HCC, most (64.0 %) were treated with intra-arterial therapy (IAT), and periprocedural morality was 2.7 %. Patients treated with IAT had longer survival versus patients receiving best support care (median survival, IAT, 12 months vs. best supportive care, 3 months; P = 0.001). Survival after IAT was similar among patients treated with infiltrating HCC versus multifocal HCC (hazard ratio 1.29, 95 % confidence interval 0.82-2.03; P = 0.27). Among infiltrating HCC patients, pretreatment bilirubin >2 mg/dL and alfa-fetoprotein >400 ng/mL were associated with worse survival after IAT (P < 0.05). Patients with progressive disease after IAT had higher risk of death versus patients who had stable/responsive disease (hazard ratio 3.53, 95 % confidence interval 1.49-8.37; P = 0.004). CONCLUSIONS: Patients with infiltrative HCC often present without a discrete lesion on imaging. IAT for infiltrative HCC was safe and was associated with survival comparable to IAT outcomes for patients with multifocal HCC. Infiltrative HCC morphology is not a contraindication to IAT therapy in select patients.

RESUMEN

INTRODUCTION: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. It is traditionally difficult to cure, especially when discovered at later stages, making early diagnosis and intervention of paramount importance. HCC typically arises in the background of chronic liver disease and can have various morphologic appearances. One of the most difficult of these to recognize on early surveillance imaging is the infiltrative subtype, which can account for up to 13% of all HCC cases, and may be more closely associated with background hepatitis B infection. DISCUSSION: Certain imaging characteristics can provide vital clues, including differing signal intensity on the T1 and T2 sequences of magnetic resonance imaging (MRI) and the presence/appearance of portal vein thrombus. Owing to the diffuse and infiltrating properties of this tumor, surgical resection and transplantation are rarely if ever viable therapeutic options. Other forms of liver-directed therapy have been attempted with limited success, having minimal efficacy and high morbidity. To date, there is no data available to determine if the various HCC subtypes respond to systemic therapy differently, so this may be the most reasonable approach. Left untreated, observed patients commonly progress to hepatic failure fairly rapidly. CONCLUSION: Infiltrative HCC can be extremely subtle, and therefore difficult to detect, especially in the background of cirrhosis. Providers caring for patients with hepatitis, chronic liver disease, and cirrhosis must be extremely vigilant in the evaluation of surveillance imaging in order to potentially discover this HCC subtype as early as possible and initiate a multidisciplinary treatment plan.

RESUMEN

BACKGROUND: Pancreatico-jejunostomy strictures (PJS) after pancreatiocoduodenectomy (PD) are poorly understood. METHODS: Patients treated for PJS were identified from all PDs (n = 357) performed for all indications in our practice (2002 to 2009). Technical aspects of the original operation, as well as the presentation, management and outcomes of the resultant stricture were assessed. RESULTS: Seven patients developed a symptomatic PJS for an incidence of 2%. 'Soft' glands and small ducts (
