Gastric necrosis and perforation following treatment of Dieulafoy's lesion with embolization of multiple gastric arteries: A case report.

Diagnosis, management, and treatment of Dieulafoy's lesion have been complicated since its first mention in 1884. With increased awareness over the decades, Dieulafoy's lesions are being managed differently based on the physician's expertise. Herein, we report a case of a 58-year-old female who was found to have a Dieulafoy's lesion on endoscopy, with her treatment complicated by gastric necrosis and perforation after multiple embolizations and limited surgical resection.

Obscure gastrointestinal bleeding localization using preoperative super-selective mesenteric angiography and intraoperative methylene blue injection: A case report and literature review.

INTRODUCTION: Currently available diagnostic tests for localizing the source of gastrointestinal bleeding include esophagogastroduodenoscopy, colonoscopy, push enteroscopy, video capsule endoscopy, deep enteroscopy, nuclear scan, angiography, radiographic contrast studies of the small bowel, intraoperative enteroscopy, and computed tomography scanning. Despite these diagnostic modalities obscure gastrointestinal bleeding (OGIB) can be difficult to localize, making surgical intervention challenging. PRESENTATION OF CASE: We report the case of a 78-year-old patient who presented with OGIB, melena and passing bright red blood per rectum, with a hemoglobin of 4.8 g/dl requiring multiple blood transfusions. Initially the source of the bleeding was difficult to identify. Eventually, a preoperative superior mesenteric angiogram was performed, identifying an arteriovenous malformation (AVM) within the small bowel as the source of OGIB. Intraoperative methylene blue was then injected through the previously placed angiogram catheter to further localize the bowel segment with the lesion. DISCUSSION: Despite multiple diagnostic modalities, OGIB, especially originating in the small bowel, is challenging to localize, making surgical intervention difficult. Methylene blue is frequently used intraoperatively to properly identify anatomic landmarks. CONCLUSION: In cases of OGIB, superselective mesenteric angiography (SSMA) with intraoperative methylene blue injection can be used as an adjunct to routine diagnostic modalities to guide surgical interventions for controlling hemorrhage and for limiting the extent of bowel resection.

Rare documented case report of a retroperitoneal hernia as a complication to an anterior retroperitoneal spinal exposure.

INTRODUCTION: Anterior retroperitoneal spinal exposures are widely used today for spinal surgeries. Incisional hernias are a documented complication of anterior spine exposures; however, there are no documented cases of hernias into the dissected retroperitoneal space. We presented this exceptionally rare patient's complication to underscores the critical importance of preserving the peritoneum as a biologic barrier during retroperitoneal spine exposures. PRESENTATION OF CASE: An obese 54 year-old female with a history of two recurrent small bowel obstructions treated conservatively after a retroperitoneal spinal exposure presented with another small bowel obstruction. The patient was taken to the operating room for exploratory laparotomy. Intraoperatively, the patient was found to have multiple loops of small bowel herniated through a small defect in the peritoneum. The small bowel was severely adherent to the retroperitoneum, resulting in torsion and obstruction. DISCUSSION: Based on intraoperative findings, we feel that the retroperitoneal hernia was directly related to the anterior lumbar spine exposure, in which peritoneal disruption is a well-reported phenomenon. There was mention of a peritoneal defect noted during the spine exposure procedure, with attempts to primarily close the defect. CONCLUSION: While disruption of the peritoneum occurs not infrequently during these primarily retroperitoneal procedures, this case should serve as a cautionary tale and reinforce the need for identification and immediate repair of any peritoneal defects that may be created during this type of procedure.

Comparative durability and costs analysis of ventricular shunts.

OBJECTIVE: Ventricular shunt (VS) durability has been well studied in the pediatric population and in patients with normal pressure hydrocephalus; however, further evaluation in a more heterogeneous adult population is needed. This study aims to evaluate the effect of diagnosis and valve type-fixed versus programmable-on shunt durability and cost for placement of shunts in adult patients. METHODS: The authors retrospectively reviewed the medical records of all patients who underwent implantation of a VS for hydrocephalus at their institution over a 3-year period between August 2013 and October 2016 with a minimum postoperative follow-up of 6 months. The primary outcome was shunt revision, which was defined as reoperation for any indication after the initial procedure. Supply costs, shunt durability, and hydrocephalus etiologies were compared between fixed and programmable valves. RESULTS: A total of 417 patients underwent shunt placement during the index time frame, consisting of 62 fixed shunts (15%) and 355 programmable shunts (85%). The mean follow-up was 30 ± 12 (SD) months. The shunt revision rate was 22% for programmable pressure valves and 21% for fixed pressure valves (HR 1.1 [95% CI 0.6-1.8]). Shunt complications, such as valve failure, infection, and overdrainage, occurred with similar frequency across valve types. Kaplan-Meier survival curve analysis showed no difference in durability between fixed (mean 39 months) and programmable (mean 40 months) shunts (p = 0.980, log-rank test). The median shunt supply cost per index case and accounting for subsequent revisions was $3438 (interquartile range $2938-$3876) and $1504 (interquartile range $753-$1584) for programmable and fixed shunts, respectively (p < 0.001, Wilcoxon rank-sum test). Of all hydrocephalus etiologies, pseudotumor cerebri (HR 1.9 [95% CI 1.2-3.1]) and previous shunt malfunction (HR 1.8 [95% CI 1.2-2.7]) were found to significantly increase the risk of shunt revision. Within each diagnosis, there were no significant differences in revision rates between shunts with a fixed valve and shunts with a programmable valve. CONCLUSIONS: Long-term shunt revision rates are similar for fixed and programmable shunt pressure valves in adult patients. Hydrocephalus etiology may play a significant role in predicting shunt revision, although programmable valves incur higher supply costs regardless of initial diagnosis. Utilization of fixed pressure valves versus programmable pressure valves may reduce supply costs while maintaining similar revision rates. Given the importance of developing cost-effective management protocols, this study highlights the critical need for large-scale prospective observational studies and randomized clinical trials of ventricular shunt valve revisions and additional patient-centered outcomes.

Racial and Socioeconomic Disparities in Hysterectomy Route for Benign Conditions.

BACKGROUND: The aim of this paper was to explore disparities associated with the route of hysterectomy in the University of Pittsburgh Medical Center (UPMC) health system and to evaluate whether the hysterectomy clinical pathway implementation impacted disparities in the utilization of minimally invasive hysterectomy (MIH). METHODS: We performed a retrospective medical record review of all the patients who have undergone hysterectomy for benign indications at UPMC-affiliated hospitals between fiscal years (FY) 2012 and 2014. RESULTS: A total number of 6373 hysterectomy patient cases were included in this study: 88.7% (5653) were European American (EA), 11.02% (702) were African American (AA), and the remaining 0.28% (18) were of other ethnicities. We found that non-EA, women aged 45-60, traditional Medicaid, and traditional Medicare enrollees were more likely to have a total abdominal hysterectomy (TAH). Residence in higher median income zip code (> $61,000) was associated with 60% lower odds of undergoing TAH. Both FY 2013 and 2014 were associated with significantly lower odds of TAH. Logistic regression results from the model for non-EA patients for FY 2012 and FY 2014 demonstrated that FY and zip code income group were not significant predictors of surgery type in this subgroup. Pathway implementation did not reduce racial disparity in MIH utilization. CONCLUSION: This study demonstrated that there is a significant disparity in MIH utilization, where non-EA and Medicaid/Medicare recipients had higher odds of undergoing TAH. Further research is needed to investigate how care standardization may alleviate healthcare disparities.

Implementation of Hysterectomy Pathway: Impact on Complications.

OBJECTIVE: Hysterectomy is one of the most common surgical procedures in the United States. For women who need hysterectomy, it is important to ensure that minimally invasive hysterectomy procedures are used appropriately to reduce surgical complications and improve value of care. Although we previously demonstrated a reduction in total abdominal hysterectomy rates after the implementation of hysterectomy pathway treatment algorithm in 2012, this study focuses on exploring the effect of pathways implementation on surgical outcomes. METHODS: All retrospective medical records for hysterectomy surgeries performed for benign indications at University of Pittsburgh Medical Center hospitals between the fiscal years (FY) 2012 and 2014 were identified. We analyzed the health care outcomes by route of surgery and year using Χ2 test for categorical data, and non-parametric approaches for non-normal continuous variables. RESULTS: A total of 6,569 hysterectomies for benign indications were performed between FY 2012 and 2014. In FY 2012, 1,154 patients (59.15%) had a length of stay of 1 day or less, whereas in FY 2014 this number increased to 1,791 (74.53%; p < .0001). Within 3 years of implementing the pathway, surgical site infections had a reduction of 47%, with a considerable trend toward significance (p = .067). CONCLUSIONS: Implementation of hysterectomy pathway has been associated with reduction of surgical complications in benign hysterectomy settings. Implementation of clinical pathways offers an opportunity for improving patient outcomes that should be investigated in various health care settings and across procedures.

Changes in Hysterectomy Trends After the Implementation of a Clinical Pathway.

OBJECTIVE: To investigate the effect of hysterectomy pathway implementation on the proportion of total abdominal hysterectomy (TAH) procedures performed between fiscal years 2012 and 2014. METHODS: We conducted a retrospective medical record review. All hysterectomy surgeries performed for benign indications at University of Pittsburgh Medical Center hospitals from fiscal year 2012 to fiscal year 2014 were identified through various systems including Medipac and EpicCare. We analyzed the cases by surgical approach (TAH compared with minimally invasive hysterectomy), age, and indication of surgery. Changes over time were analyzed using Cochran-Armitage test for linear trends. RESULTS: A total number of 6,544 patients were included in this study. The mean age of the participants was 48.6 years (standard deviation 11.69). In fiscal year 2012, of 1,934 hysterectomies performed as a result of noncancerous conditions, 538 were TAH procedures (27.8%). However, this number declined in fiscal year 2013 to 22% (485 TAH procedures of 2,186 hysterectomies) and further declined in fiscal year 2014 to 17% (413 TAH surgeries of 2,424 hysterectomies). Overall, there was a significant reduction in the proportion of TAH procedures, from 27.8% in fiscal year 2012 to 17% in fiscal year 2014 (P for trend <.001). After adjusting for surgery indication, the decreasing trend of TAH procedures still persisted (P for trend <.001). CONCLUSION: Implementation of a hysterectomy pathway has been associated with a decrease in the proportion of TAH hysterectomy procedures.
