Rectal Colonic Mural Hematoma Following Enema For Constipation While On Therapeutic Anticoagulation., Rebecca M. Rentea, Charles H. Fehring

Manuscripts, Articles, Book Chapters and Other Papers

Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmonary embolism, was administered an enema resulting in severe abdominal pain unresponsive to blood transfusion. A sigmoid colectomy with end colostomy was performed. Although rare, colonic and recto-sigmoid hematomas should be considered as a possible diagnosis for adults with abdominal pain on anticoagulant therapy.

Manuscripts, Articles, Book Chapters and Other Papers

Background. Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. The purpose of this study was to evaluate the diagnostic value and safety of double-balloon enteroscopy (DBE) for bleeding MD in children. Methods. We included consecutive children who were highly suspected of MD between 2012 and 2013. All patients underwent Meckel's scan. DBE was performed for patient with negative Meckel's scan. An exploratory laparoscopy was performed in children with positive Meckel's scan or DBE. Results. 42 patients met the inclusion criteria. 40 patients were confirmed to have MD by exploratory laparoscopy. Meckel's scan …

Outcomes After Pediatric Fundoplication: Defining The Redo Population, J E. Baerg, E E. Perrone, R A. Vannix, D L. Thorpe, A Gasior, Shawn D. St Peter

Manuscripts, Articles, Book Chapters and Other Papers

Objective: The aims were to compare outcome variables in children with gastroesophageal reflux disease (GERD) and one Nissen fundoplication to children with redo fundoplications and define the pediatric redo population. Methods: After IRB approval (#5100277), a case control study was conducted of children younger than 18 years, from two children’s hospitals, with one Nissen fundoplication (control group) or a redo performed between January 1995 and March 2011. Complete data were collected by phone calls to caregivers in December 2012. Only redo operations performed after recurrence of GERD symptoms and wrap herniation into the mediastinum confirmed by contrast radiograph were included. …

BACKGROUND: Compared with elective surgical procedures, emergency procedures are associated with higher cost, morbidity, and mortality. This study seeks to investigate potential state-by-state variations in the incidence of emergent versus elective colon resections.

METHODS: A retrospective analysis of all adult patients (aged ≥18 years) included in the Nationwide Inpatient Sample from 2005 to 2009 who underwent hemicolectomy (right or left) or sigmoidectomy was conducted. Discharge-level weights were applied, and generalized linear models were used to assess the odds of a patient undergoing emergent versus elective colon surgery nationally and for each state after adjusting for patient and hospital factors. Odds …

Mast Cell Activation And Clinical Outcome In Pediatric Cholelithiasis And Biliary Dyskinesia., Craig A. Friesen, Nancy Neilan, James F. Daniel, Kim Radford, Jennifer Verrill Schurman, Ding-You Li, Linda Andre, Shawn D. St Peter, G W. Holcomb Iii

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The current study was undertaken to determine the degree of activation of gallbladder mucosal mast cells, whether mast cell (MC) density or activation differ between patients with and without a positive clinical response to cholecystectomy, and whether either density or activation correlate with gallbladder emptying.

RESULTS: Fifteen biliary dyskinesia (BD) and 13 symptomatic cholelithiasis (CL) patients undergoing cholecystectomy were prospectively enrolled. Gallbladder wall MC density (by immunohistochemistry) and activation (by electron microscopy) were determined. Clinical response was evaluated 30 days post-cholecystectomy on a 5-point Likert-type scale. A complete or nearly complete clinical response was seen in 100% of CL …

Minimal Vs Extensive Esophageal Mobilization During Laparoscopic Fundoplication: A Prospective Randomized Trial., Shawn D. St Peter, Douglas C. Barnhart, Daniel J. Ostlie, Kuojen Tsao, Charles M. Leys, Susan W. Sharp, Donna Bartle, Tracey Morgan, Carroll M. Harmon, Keith E. Georgeson, G W. Holcomb Iii

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Laparoscopic Nissen fundoplication has been traditionally performed with extensive esophageal dissection to create 2 to 3 cm of intraabdominal esophagus. Retrospective data have suggested that minimal esophageal mobilization may reduce the risk of postoperative herniation of the wrap into the lower mediastinum. To compare complete esophageal dissection to leaving the phrenoesophageal attachment intact, we conducted a 2-center, prospective, randomized trial.

METHODS: After obtaining permission/assent, patients were randomized to circumferential division of the phrenoesophageal attachments (MAX) or minimal mobilization with no violation of the phrenoesophageal membrane (MIN). A contrast study was performed at 1 year. The primary outcome variable was …

Should We Be Concerned About Jejunoileal Atresia During Repair Of Duodenal Atresia?, Shawn D. St Peter, Danny C. Little, Katherine A. Barsness, Daniel R. Copeland, Casey M. Calkins, Suzanne Yoder, Steve S. Rothenberg, Saleem Islam, Kuojen Tsao, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: During repair for duodenal atresia, it has been emphasized that inspection of the small bowel to identify a second atresia is required. The laparoscopic approach for repair of duodenal atresia has been criticized for its limitation to perform this step. Given that duodenal atresia and jejunoileal atresias do not share common embryologic origins, we question the validity of this concern. Therefore, we conducted a multicenter retrospective review of duodenal atresia patients to quantify the incidence of jejunoileal atresia in this population.

METHODS: After institutional review board approval (IRB #07-12-187X), a retrospective review was conducted on all patients who have …

Asian Race/Ethnicity As A Risk Factor For Bile Duct Injury During Cholecystectomy., Stephanie R. Downing, Ghazala Datoo, Tolulope A. Oyetunji, Terrence Fullum, David C. Chang, Nita Ahuja

Manuscripts, Articles, Book Chapters and Other Papers

Iatrogenic bile duct injury (BDI) is an uncommon but serious complication of cholecystectomy, with identified risk factors of acute cholecystitis, male sex, older age, and aberrant biliary anatomy. The Nationwide Inpatient Sample (1998-2006) was queried for cholecystectomy performed on hospital day 0 or 1. Bile duct injury repair procedure codes were used as a surrogate for BDI. We identified 377,424 patients who underwent cholecystectomy, with 1124 BDIs (0.3%). On multivariate logistic regression analysis, Asian race/ethnicity was a significant risk factor for BDI (odds ratio [OR], 2.26; 95% confidence interval [CI], 1.59-3.23; P < .001). This persisted for laparoscopic (OR, 2.62; 95% CI, 1.28-5.39; P = .009) and open (2.21; 1.59-3.07; P < .001) cholecystectomies. No other race/ethnicity was identified as a risk factor for BDI. We report a new finding that Asian race/ethnicity is a significant risk factor for BDI in laparoscopic and open cholecystectomies.

Management Of Pediatric Acute Appendicitis In The Computed Tomographic Era., Kuojen Tsao, Shawn D. St Peter, Patricia A. Valusek, Troy L. Spilde, Scott J. Keckler, Abhilash Nair, Daniel J. Ostlie, G W. Holcomb Iii

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND/PURPOSE: The treatment options for complicated appendicitis in children continue to evolve. Optimal management of complicated appendicitis relies on an accurate preoperative diagnosis. We examined the accuracy of our preoperative diagnosis including computed tomography (CT) and the influence on the management of children with perforated and nonperforated appendicitis.

METHODS: Following IRB approval, a 6-year review of all patients that underwent an appendectomy for suspected appendicitis was performed. Treatments included immediate operations and initial nonoperative management (antibiotic therapy +/- percutaneous drainage of abscess). Appendicitis was confirmed by histological examination.

RESULTS: One thousand seventy-eight patients underwent appendectomy for suspected appendicitis. Preoperative CT …

Current Significance Of Meconium Plug Syndrome., Scott J. Keckler, Shawn D. St Peter, Troy L. Spilde, Kuojen Tsao, Daniel J. Ostlie, G W. Holcomb Iii, Charles L. Snyder

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The significance of meconium plug syndrome is dependent on the underlying diagnosis. The incidence of pathologic finding, particularly Hirschsprung's disease, contributing to the presence of these plugs, has been debated. However, there are little recent data in the literature. Therefore, we reviewed our experience with meconium plugs as a cause of abdominal distension to evaluate the associated conditions and incidence of Hirschsprung's disease.

METHODS: We reviewed the records of newborns with meconium plugs found in the distal colon on contrast enema from 1994 to 2007. Demographics, radiologic findings, histologic findings, operative findings, and clinical courses were reviewed.

RESULTS: During …

Gastroesophageal Reflux Disease And Fundoplication In Infants And Children, Shawn D. St Peter, G W. Holcomb Iii

Manuscripts, Articles, Book Chapters and Other Papers

Gastroesophageal reflux disease (GERD) can be one of the most distressing conditions developing at different ages in infants and children. The disease itself is a complex process along with ongoing dynamic anatomic and physiologic changes occurring during normal development. Therefore among referring physicians, considerations regarding the role of surgery for GERD in children varies widely depending on individual experiences in managing these patients. These varied opinions result in discrepancies in the operative experience with fundoplication among pediatric surgeons. It is unclear how much of the current opinions stem from published evidence, particularly with regard to the safety and efficacy of …
