Abstract
The primary aim of this study was to define predictors of computed tomography (CT)-guided percutaneous abscess drainage treatment failure in complicated diverticulitis. A 10-year retrospective analysis of inpatients seen in surgical consultation for diverticular abscess management subsequently referred for CT-guided percutaneous drainage (PD) was conducted. The clinical courses of patients undergoing a technically successful PD were categorized into three groups: 1) no colectomy; 2) elective colectomy; and 3) nonelective colectomy. Forty study patients were identified. Thirteen (33%) of the 40 patients required a nonelective colectomy, 20 patients (50%) underwent elective resection, and seven patients (18%) have been managed nonoperatively with no recurrent diverticulitis for a median of 46.8 months (range, 3.2 to 84.3 months). Forward logistic regression identified the presence of immunosuppression or renal insufficiency (creatinine 1.5 mg/dL or greater) as factors independently associated with failure of PD and need for non-elective colectomy. No clinical, laboratory, or radiologic variables were predictive of long-term nonoperative success. Although PD allows for the resolution of intra-abdominal sepsis for most cases of diverticulitis complicated by an abscess, a substantial proportion progress to nonelective colectomy, emphasizing the need for clinical vigilance in follow-up.

Abstract
AIM Endoanal ultrasound (EAUS) is the gold standard for detecting anal sphincter defects in patients with faecal incontinence (FI), while anorectal manometry evaluates sphincter function. Three-dimensional high-resolution anorectal manometry (3D HRAM) is a newer modality with the potential to assess both sphincter function and anatomy. The purpose of the present study was to compare 3D HRAM with 3D EAUS for the detection of anal sphincter defects in patients with FI. METHOD A linkage analysis was performed between the 3D HRAM and 3D EAUS databases of a tertiary referral centre to identify patients with FI who underwent both 3D EAUS and 3D HRAM. With 3D HRAM, a defect was defined as any pressure measurement below 25 mmHg at rest with at least 18° of continuous expansion. The 3D HRAM findings were compared with those of 3D EAUS. RESULTS The study cohort included 39 patients with a mean age of 64.7 ± 15.2 years (SD); and 31 (79%) were female. Eight (21%) patients had an anal sphincter defect on EAUS with a median size of 93° (range 40°-136°). Fourteen (36%) had a defect shown by 3D HRAM with a median size of 144° (36°-180°). The sensitivity, specificity and positive and negative predictive values of 3D HRAM in detecting a sphincter defect were 75%, 74%, 43% and 92%, respectively. CONCLUSION With a negative predictive value of 92%, 3D HRAM may be a useful screening method for ruling out a sphincter defect in patients with FI, thereby avoiding both EAUS and manometry in selected patients.

Abstract
INTRODUCTION Although the auscultation of bowel sounds is considered an essential component of an adequate physical examination, its clinical value remains largely unstudied and subjective. OBJECTIVE The aim of this study was to determine whether an accurate diagnosis of normal controls, mechanical small bowel obstruction (SBO), or postoperative ileus (POI) is possible based on bowel sound characteristics. METHODS Prospectively collected recordings of bowel sounds from patients with normal gastrointestinal motility, SBO diagnosed by computed tomography and confirmed at surgery, and POI diagnosed by clinical symptoms and a computed tomography without a transition point. Study clinicians were instructed to categorize the patient recording as normal, obstructed, ileus, or not sure. Using an electronic stethoscope, bowel sounds of healthy volunteers (n = 177), patients with SBO (n = 19), and patients with POI (n = 15) were recorded. A total of 10 recordings randomly selected from each category were replayed through speakers, with 15 of the recordings duplicated to surgical and internal medicine clinicians (n = 41) blinded to the clinical scenario. The sensitivity, positive predictive value, and intra-rater variability were determined based on the clinician's ability to properly categorize the bowel sound recording when blinded to additional clinical information. Secondary outcomes were the clinician's perceived level of expertise in interpreting bowel sounds. RESULTS The overall sensitivity for normal, SBO, and POI recordings was 32%, 22%, and 22%, respectively. The positive predictive value of normal, SBO, and POI recordings was 23%, 28%, and 44%, respectively. Intra-rater reliability of duplicated recordings was 59%, 52%, and 53% for normal, SBO, and POI, respectively. No statistically significant differences were found between the surgical and internal medicine clinicians for sensitivity, positive predictive value, or intra-rater variability. Overall, 44% of clinicians reported that they rarely listened to bowel sounds, whereas 17% reported that they always listened. CONCLUSIONS Auscultation of bowel sounds is not a useful clinical practice when differentiating patients with normal versus pathologic bowel sounds. The listener frequently arrives at an incorrect diagnosis. If routine abdominal auscultation is to be continued, our findings emphasize the need for improvements in training and education as well as advancements in the understanding of the objective acoustical properties of bowel sounds.

Abstract
BACKGROUND Crohn's disease (CD) is considered a contraindication to ileal pouch--anal anastomosis (IPAA). In this study, we compare outcomes of CD and ulcerative colitis (UC) patients undergoing IPAA. METHODS Patients were considered to have CD before surgery based on a history of small bowel disease, perianal disease, noncrypt-associated granuloma, or pretreatment skip colonic lesions. Patients were prospectively assessed for pouchitis or CD. Postoperative CD (pouch inflammation into the afferent limb or pouch fistula) or pouch failure (need for permanent diversion) were assessed. Preoperative serum was assayed for IBD-associated antibodies using enzyme-linked immunosorbent assay (ELISA). RESULTS Seventeen patients with preoperative CD were identified. Seven (41%) patients developed postoperative recurrent CD in the afferent limb (n = 3) or pouch fistulizing disease (n = 4). One patient (6%) required pouch excision. The incidence of postoperative CD was higher (P = 0.002) in preoperative CD patients (41%) than UC patients (11%). There was no significant difference in pouchitis or pouch failure. There was also no significant difference in any preoperative clinical feature between patients with or without postoperative CD. Afferent limb inflammation developed in three (50%) of the six patients with pANCA+/OmpC- expression compared to none of the 11 patients without this serologic profile (P = 0.03). CONCLUSIONS Although the intentional use of IPAA in CD has a higher incidence of postoperative disease vs. UC patients, there was no significant difference in pouch failure. Demographics, clinical features, and serologic factors do not predict outcome of CD patients undergoing IPAA. IBD serology may identify the phenotype manifestation of postoperative recurrent CD.

Abstract
BACKGROUND Although postoperative ileus (POI) is a common complication after major abdominal colorectal surgery, it is unknown whether a history of POI predisposes to recurrent POI in subsequent surgeries. In the present retrospective case-control study, conducted at the colorectal surgery division of a tertiary care center, we attempted to identify factors that may predict recurrent POI in ulcerative colitis (UC) patients undergoing three-stage ileal pouch-anal anastomosis (IPAA). METHODS Charts of UC patients undergoing three-stage IPAA were reviewed. All patients received a standardized accelerated postoperative care pathway. Patients were assigned to one of 3 categories: Group A patients did not have POI after either initial subtotal colectomy (STC) or subsequent IPAA, Group B patients developed POI only after initial STC, and Group C patients developed POI after both STC and IPAA. RESULTS The study group consisted of 91 patients. There were 71 (78 %) patients in Group A, 14 (15 %) patients in Group B, and 6 (7 %) patients in group C. There was no significant difference in any demographic or clinical features among patients that developed no POI, those that developed POI only after STC, and those that developed POI after both STC and IPAA. CONCLUSIONS POI is difficult to predict after first- and second-stage IPAA. Clinical factors and a history of POI from first-stage IPAA do not predict POI after second-stage IPAA. Patients with a history of POI after STC do not have an increased risk of developing recurrent POI.

Abstract
Postoperative diet advancement in patients undergoing elective small bowel or colorectal surgery by general surgeons (GSs) and colorectal surgeons (CRSs) was prospectively evaluated. Demographic (age and gender), disease location (small bowel or colorectum), surgical approach (laparoscopic or open), and surgeon characteristics (GS or GRS) were tabulated. Postoperative feeding after surgery on postoperative Day (POD) 1 was assessed. Operations involved the colorectum (n = 43 [72%]) or small bowel (n = 17 [28%]) and were performed using laparoscopy (n = 38 [63%]) or open (n = 22 [37%]) techniques. Operations were performed by GSs (n = 30) or CRSs (n = 30). Early feeding was ordered on POD 1 on 34 patients (57%). The remaining 26 patients (43%) were kept nothing by mouth. Factors associated with early feeding included age younger than 50 years (P 5.004), surgery done by CRSs ( P < 0.0001), operations on the colorectum ( P = 0.04), and laparoscopic surgery ( P = 0.07). Multivariable analysis revealed that age younger than 50 years (odds ratio [OR], 9.5; 95% confidence interval [CI], 1.8 to 52; P = 0.01), surgery done by CRSs (OR, 16.3; 95% CI, 3.4 to 79.6; P = 0.001), and use of laparoscopic surgery (OR, 12; 95% CI, 2.1 to 67; P = 0.007) were associated with early postoperative feeding. Early postoperative feeding does not appear to be applied commonly in clinical practice. Younger patient age, surgery done by CRSs, and laparoscopy are associated with the use of early postoperative feeding after elective intestinal surgery.

Abstract
BACKGROUND Laparoscopic surgery has become a favorable alternative to conventional open surgery for the creation of intestinal stomas, and it offers many benefits including reduced postoperative pain, ileus, and hospital stay. Single-incision laparoscopic surgery has been described for many abdominal operations. It may offer better cosmetic outcomes and reduce incisional pain, adhesions, and recovery time. OBJECTIVE In this study, we aimed to describe a novel technique of scarless single-incision laparoscopic loop ileostomy for fecal diversion and to report our experience with 8 patients who underwent this procedure within a 1-year period. DESIGN This study was designed as a retrospective case series. SETTINGS This investigation was conducted at a single-institution, tertiary referral center. PATIENTS Eight consecutive patients undergoing scarless single-incision laparoscopic loop ileostomy between August 2009 and August 2010 were included. INTERVENTION Scarless single-incision laparoscopic loop ileostomies were performed. MAIN OUTCOME MEASURES Among the outcomes measured were operation time, intraoperative blood loss, recovery of intestinal function, length of hospital stay, and surgical complications. RESULTS Seven patients underwent surgery for active Crohn's disease refractory to medical therapy. One patient underwent surgery for radiation-induced rectovesical fistula. Median surgery time was 76 minutes, and median intraoperative blood loss was 10 mL. Median length of postoperative hospitalization was 7 days. Of the 8 patients included in our series, 2 patients (25%) required reoperation for stoma ischemia because of vascular congestion that we attribute to a tight fascial opening or extensive bowel manipulation. Other surgical complications included nonoperative readmission for ileus and partial small-bowel obstruction (n = 2), anal dilation to evacuate an obstructed distal colon (n = 1), and peristomal cellulitis (n = 1). LIMITATIONS This study was limited by its small sample size and its retrospective nature. CONCLUSION Scarless single-incision laparoscopic loop ileostomy is a feasible alternative to standard laparoscopy for fecal diversion. Surgeons attempting this technique should do so with caution, given the high stoma ischemia rate in our small case series.

Abstract
Patients previously on corticosteroids within 1 year before surgery are routinely treated with perioperative high-dose corticosteroids. However, there is little evidence to support this practice. We postulated that patients off steroids but treated with corticosteroids within 1 year before surgery may be safely managed without perioperative steroids. A chart review was performed on patients with inflammatory bowel disease (IBD) treated with corticosteroids within 1 year before surgery. Patients received either perioperative high-dose steroids (HDS) or no steroids (NS). Perioperative vital signs were assessed. Forty-nine operations were performed. Eleven patients received HDS and 38 patients received NS. Aside from a higher incidence of tachycardia (heart rate greater than 100 beats/min) in the HDS group (82%) compared with the NS group (42%), there was no significant difference in hemodynamic instability between the two groups. One patient in the NS group required a single dose of intraoperative vasopressor after aggressive beta-blockade. All other episodes of hemodynamic instability resolved with no intervention, fluid boluses, or blood transfusion. No patients required rescue high-dose steroids for adrenal insufficiency. In patients with IBD undergoing major colorectal surgery, treated with corticosteroids within the past year, management without perioperative steroids seems safe. A prospective study assessing perioperative corticosteroid dosing is in progress.

A prospective study assessing perioperative corticosteroid dosing is in progress.

Abstract
BACKGROUND Previous studies have reported that as many as one third of applicants misrepresent their publication record on residency or fellowship applications. OBJECTIVE To determine the incidence of potentially fraudulent (or "phantom") research publications among applicants to a colorectal surgery residency program. DESIGN Electronic Residency Application Services applications were reviewed. All listed publications were tabulated and checked whether they were published using various search engines. SETTING Cedars-Sinai Medical Center. PATIENTS Applicants from 2006 to 2008. MAIN OUTCOME MEASURES We searched for phantom publications, defined as peer review journal citations that could not be verified. Demographics and other academic factors were compared between applicants with phantom publications and applicants with verifiable publications. RESULTS Of the 133 study group applicants, there were 91 (68%) males and 58 (44%) whites. Median age of the study cohort was 32 years (range, 27-48 y). Eight-seven of 130 applicants (65%) listed a total of 392 publications. Thirty-six (9%) of these 392 citations could not be verified and were considered to be phantom publications. The 36 phantom publications were identified in 21 applicants, representing 16% (21/133) of all applicants and 24% (21/87) of all applicants who cited publications. We found no significant difference in any demographic or other studied variable between applicants with phantom publications and those with verifiable publications. When comparing applicants with 3 or more phantom publications with applicants with verifiable publications, the former group had a significantly higher rate of individuals over age 35 (50% vs 24%; P = .02), foreign medical school graduates (75% vs 20%; P = .03), and individuals with 5 or more publications (100% vs 30%; P = .01). LIMITATIONS Publications may simply have been missed in our search. We specifically may have failed to find publications in foreign journals. CONCLUSION The significance of professionalism and ethical behavior must be emphasized in surgery training programs.

Abstract
Previous papers studying the effect of surgeon experience on patient outcomes after colorectal surgery are hampered by study design, variable measurements of outcome, and have shown conflicting results. The National Surgical Quality Improvement Program is a validated, risk-adjusted, outcomes-based program used to measure the quality of surgical care. Here, we sought to determine the association between colorectal surgeon experience and short-term patient outcomes using a colorectal surgery-specific National Surgical Quality Improvement Program methodology. We prospectively followed 300 patients operated on by eight colorectal surgeons. The median age was 46 years, male:female ratio was 163:137, and median body mass index was 23. Surgeons were divided into two groups: those with less (Group A) than or greater (Group B) than 5 years experience. Procedures were categorized into 137 (46%) major and 163 (54%) minor cases. Group A surgeons operated on 95 (32%) patients and Group B surgeons operated on 205 (68%) patients. Postoperatively, 101 (31%) patients had complications (Group A = 29; Group B = 72). Four (1%) patients had reoperations (Group A = 0; Group B = 4) and 24 (8%) were readmitted (Group A = 5; Group B = 19) within 30 days of surgery. This prospective study revealed no significant difference in short-term outcomes between colorectal surgeons with less than versus more than 5 years experience.

Abstract
The treatment of rectal cancer has undergone a tremendous surgical evolution over the past century. Initially, in the 19th century, the only possible safe treatment was a diverting colostomy, which then evolved first to local treatment, primarily via the Lisfranc and Kraske procedures (posterior approach), and later, in the 20th century, to the abdominal-perineal resection popularized by Miles. Subsequently, anterior resection and low anterior resection gained a solid foothold as the most efficacious ways to treat most cancers of the rectum. In the past 3 decades, transanal excision has reemerged as a popular treatment option for T1 and selected T2 rectal adenocarcinomas, allowing less morbidity for early cancers. The selection criteria for this treatment have often included mobile tumor, size <4 cm, favorable histology without lymphovascular invasion, and anatomic accessibility with the ability to achieve 1-cm circumferential margins. Although the use of transanal excision for T1 rectal cancer increased from 26% to approximately 44% between 1989 and 2003, multiple recent retrospective studies have suggested that locoregional recurrence after this procedure is as high as 18% for T1 cancers and 47% for T2 cancers. Of interest, limited available prospective data reveal much better results (4-5% locoregional recurrence rate for T1 and 14-16% for T2). Much of the apparent discrepancy is due to patient selection, which is far more rigid in prospective trials. Conflicting data also exist as to how this outcome affects overall survival, although surgical salvage averages approximately 50% with close follow-up. The following topics will be discussed in this article: the surgical evolution of rectal cancer, best patient selection criteria for transanal excision versus more radical operation, utility and effect of adjuvant therapy in early-stage rectal cancer, current trends in the treatment of early-stage rectal cancer, and current early-stage rectal cancer trials.

Abstract
A retrospective study of 117 patients with the diagnosis of colon cancer was performed to evaluate the clinical utility of the preoperative computed tomography (CT) scan and to assess the role of carcinoembryonic antigen (CEA) as a predictor of the need for CT scan in colon cancer patients. Forty-nine patients had a CT scan that altered their treatment. One hundred per cent of stage IV patients versus only 26.5 per cent of stage I, II, and III patients had their operative and/or treatment planning altered by the preoperative CT. The sensitivity of CT scan in predicting metastatic disease was 90.3 per cent. All patients with stage IV disease had an abnormal CEA (>3 ng/mL). There was 89.7 per cent of stage IV patients who had a CEA twice that of normal or above. By using a CEA level of 3.1 ng/mL or above as a prerequisite for preoperative tomography, 34 nonmetastatic patients would not have had preoperative CT scans. Using a prerequisite of 6.1 ng/mL or above, 49 nonmetastatic patients would not have had a preoperative CT scan, and 90 per cent of the stage IV patients would have been imaged. We recommend obtaining a preoperative CT scan on those patients with a CEA value twice that of normal or greater.

Abstract
The purpose of this study was to determine if the quantity and age of blood is an independent risk factor for in-hospital mortality, need for intensive care unit (ICU) care, and an increased length of stay in the ICU. This was a retrospective cohort study performed at a level I trauma center between 2001 and 2003. Consecutive trauma patients who received at least 1 unit of packed red blood cells (PRBCs) were included. The number of units of PRBCs transfused and the ages of each unit of PRBCs were recorded. Other variables including the patient's age, sex, Trauma-Related Injury Severity Score (TRISS), and whether the blood was leukopoor were collected. End points included in-hospital mortality, need for ICU care, and the length of stay in the ICU (in days). Multivariable logistic and Poisson regression analyses were performed to model the independent effect of the dose of aged blood (defined as the product of the average age of all units received and the total number of units received) with respect to each end point while controlling for age, TRISS, the total number of units administered, and the proportion of blood that was leukopoor. During the study period, 275 patients were studied. Patients who received older blood had a significantly longer ICU stay (RR 1.15, 95% CI: 1.11–1.20), possibly reflecting a higher level of organ dysfunction. Patients who received older blood, however, did not have a significantly higher in-hospital mortality rate (OR 1.21, 95% CI: 0.87–1.69) or a significantly higher need for ICU care (OR 1.20, 95% CI: 0.87–1.64). The quantity of aged blood is an independent risk factor for length of ICU care. This may be a proxy indicator for multiple organ failure. Further research is required to define which patients may benefit from newer blood.

Abstract
Histoplasma capsulatum is an important pathogen that is the most commonly diagnosed endemic mycosis in the gastrointestinal tract of immunocompromised hosts. Failure to recognize and treat disseminated histoplasmosis in AIDS patients invariably leads to death. Gastrointestinal manifestations frequently involve the terminal ileum and cecum, and depending on the layer of bowel wall involved present as bleeding, obstruction, perforation, or peritonitis. Because they can be variable in appearance, they may be mistaken for Crohn's disease or malignant tumors. Four distinct pathologic patterns of GI histoplasmosis have been described that all have differing clinical presentations. We report a case of a non-AIDS patient who presented with a near-obstructing colonic mass suspicious for advanced malignancy but was found to have histoplasmosis on final pathology. The patient underwent successful operative resection, systemic antifungal therapy, and extensive workup for immunosuppressive disorders, which were negative. The patient was from an area in Mexico known to be endemic for histoplasmosis. This is the first report of a colonic mass lesion occurring in a non-AIDS patient, and review of the worldwide literature regarding GI histoplasmosis reveals excellent long-term survival with aggressive therapy. We discuss the surgical and medical management of colonic histoplasmosis in this report.

Abstract
Our previous studies demonstrated fibrin glue (FG) prepared from cryoprecipitate (cryo) inhibits intra-abdominal adhesions in rats. A new FG, Hemaseel APR, is Food and Drug Administration (FDA) approved for hemostasis during cardiac surgery and splenic trauma. This study was undertaken to determine if Hemaseel FG prevents intra-abdominal adhesions, and to compare it to cryo FG. Forty-five rats underwent laparotomy. Bilateral peritoneal-muscular defects were created. Polypropylene mesh was sewn into each defect with a running silk suture. The bowel was abraded with gauze. The rats were then randomized to mesh covered with Hemaseel FG, cryo FG, or control. On postoperative day 7, the severity of adhesions were graded by percentage of mesh covered by adhesion (0-100%) and degree of adhesion (0-3). The mean percentage of mesh covered by adhesion was 9% for Hemaseel FG, 43% for cryo FG (p = .005), and 65% for the controls (p < .0001). The mean density adhesion score was 0.5 for Hemaseel FG, 1.2 for cryo FG (p = .04), and 2.1 for the controls (p < .0001). In the Hemaseel FG group, 77% of patches had no adhesions, compared with 37% in the cryo FG group (p = .004) and 13% in the controls (p < .0001). Thus, Hemaseel FG significantly decreases intra-abdominal adhesions, and is more effective than cryo FG.

Abstract
BACKGROUND Our previous study demonstrated that Balthazar grade D or E pancreatitis on early abdominal computed tomography (CT) scan correlated with severe complications of gallstone pancreatitis (GP). OBJECTIVE To compare the efficacy of individual admission laboratory criteria, multiple criteria scoring systems and CT scan for predicting severe complications of GP. METHODS Consecutively admitted patients with GP underwent selective early CT scanning (<72 hours). All patients were prospectively monitored for severe complications. RESULTS Of the 66 patients studied, 21 (32%) did not undergo for early CT scanning and underwent cholecystectomy with no complications. Forty-five patients (68%) had an early abdominal CT scan. Of the 12 patients with grade E pancreatitis, 6 (50%) developed severe complications versus only 2 of 33 (6%) with grade A to D pancreatitis (P = 0.002). A significant correlation was found between admission white blood cell count > or =14.5 x 10(9)/L and grade E pancreatitis on early CT scan (P = 0.002). However, admission glucose > or =150 mg/dL was the best predictor of complications (sensitivity 100%, negative predictive value 100%). CONCLUSION Although Balthazar grade E on early CT scan correlates with severe complications of GP, admission glucose > or =150 mg/dL has a better sensitivity and negative predictive value, is quicker to use, and is more cost-effective as a prognostic indicator.

Abstract
HYPOTHESIS Simple admission criteria (white blood cell count, > or =14. 5 x 10(9)/L; blood urea nitrogen level, > or =4.3 mmol/L [> or =12 mg/dL]; heart rate, > or =100 beats per minute; and serum glucose level, > or =8.3 mmol/L [> or =150 mg/dL]) are better predictors of severe complications of gallstone pancreatitis than an Acute Physiology and Chronic Health Evaluation II (APACHE II) score of 5 or greater, a modified Imrie (Glasgow) score of 3 or greater, and a biliary Ranson score of 3 or greater. DESIGN A prospective consecutive case study. SETTING A university-affiliated, urban, public hospital. PATIENTS Ninety-two consecutive patients (77 women and 15 men, aged 18 to 76 years [mean age, 39 years]) with gallstone pancreatitis. Seventy-seven patients were Hispanic. MAIN OUTCOME MEASURES Major local and systemic complications requiring intensive care unit care, and death. RESULTS Fourteen patients (15%) had severe complications with a mortality of 2%. On univariate analysis, a white blood cell count of 14.5 x 10(9)/L or more (P =.03), a serum glucose level of 8. 3 mmol/L or more (> or =150 mg/dL) (P<.001), an APACHE II score of 5 or greater (P =.008), a modified Imrie score of 3 or greater (P<.001), and a biliary Ranson score of 3 or greater (P =.03) were statistically associated with the development of severe complications; whereas a blood urea nitrogen level of 4.3 mmol/L or more (> or =12 mg/dL) and a heart rate of 100 beats per minute or more were not. On multivariate analysis, only a serum glucose level of 8. 3 mmol/L or more (> or =150 mg/dL) was predictive of adverse events (P<. 001). CONCLUSIONS Glucose level (> or =8.3 mmol/L [> or =150 mg/dL]) is the best single admission predictor of severe complications of gallstone pancreatitis and is superior to an APACHE II score of 5 or greater, a modified Imrie score of 3 or greater, and a biliary Ranson score of 3 or greater.

Abstract
Aortic rupture in association with a contiguous intraabdominal abscess is rare. We report an unusual case of aortic rupture in association with a polymicrobial abscess and review the related literature. Cultures grew Eikenella corrodens, a rare intraabdominal pathogen, as well as betahemolytic streptococcus and S. viridans. The patient was successfully managed by aortic ligation followed by an extraanatomic bypass.
