Arterioureteral Fistula in the Setting of Radical Cystoprostatectomy and Ileal Conduit Creation.

Arterioureteral fistulas (AUF) following ileal conduit reconstruction are rare and not well-studied. We present a life-threatening bleed from an AUF due to an ileal conduit urinary diversion. In addition, we identify the challenges in the diagnostic process as well as management strategies. We present a 63-year-old male with ileal conduit reconstruction for bladder cancer with an AUF developing years after the reconstruction, which was ultimately managed with angioplasty.

Investigating the incidence, impact, and severity of pulmonary complications after hepatectomy: A single institution experience.

BACKGROUND: Postoperative pulmonary complications are a common cause of postoperative morbidity in patients undergoing hepatectomy. This study aimed to identify risk factors, define severity, and evaluate the impact of postoperative pulmonary complications on postoperative morbidity after hepatectomy. METHOD: We used a prospective database in identifying all hepatectomies from 2013 to 2018. The database was then augmented using extensive review of medical records. The Strasburg system was used in categorizing resections per complexity: major hepatic resection and minor hepatic resection, whereas the Clavien-Dindo system was used in defining postoperative pulmonary complications per severity. Potential confounders were controlled for on multiple regression models. RESULTS: A total of 702 cases were identified: major hepatic resection 413 (60%) and minor hepatic resection 289 (40%). Patients demonstrated comparable characteristics, but the postoperative pulmonary complications group was more likely to have chronic obstructive pulmonary disease (10% vs 5%; P = .02). Severe postoperative pulmonary complications among major hepatectomy was observed in 38 patients (13%). Predictors for severe postoperative pulmonary complications requiring intervention included postoperative liver failure (odds ratio = 2.8; P = .002) and biliary fistula (odds ratio = 3.5; P = .001). In addition, the occurrence of severe postoperative pulmonary complications markedly hindered recovery, increasing length of stay by 4.4-fold and readmission rates by 3-fold (P < .001). On multivariable analysis, postoperative pulmonary complications significantly increase postoperative length of stay (8 vs 5 days; P < .001) and readmission (odds ratio = 3.2; P = .001). Mortality was similar (1% vs 4%; P = .066). CONCLUSION: Postoperative pulmonary complications are a major cause of delayed recovery and worse outcomes after hepatectomy. Further, postoperative liver failure and biliary fistula can predict the occurrence of severe postoperative pulmonary complications among major hepatic resection and the associated need for readmission with these complications.

A Jejunal Dieulafoy Lesion: Rare Case Necessitating Surgical Intervention.

INTRODUCTION: Dieulafoy lesions are enlarged atypical submucosal vessels that erode the superimposing epithelium in the absence of a primary ulcer. They occur predominantly in the gastric mucosa; however, cases have been seen throughout the gastrointestinal (GI) tract, and rarely, the jejunum. These lesions can cause massive GI hemorrhage leading to shock. CASE PRESENTATION: We present a healthy 19-year-old male who arrived at our institution's emergency department with multiple episodes of hematemesis and hematochezia that began earlier that morning. The patient was resuscitated and underwent a computerized tomographic (CT) angiography that did not identify any areas of active extravasation. The patient was then taken for an emergent upper and lower endoscopy that was inconclusive. He was subsequently sent for a tagged red blood cell scan, which demonstrated active bleeding in the proximal jejunum. Shortly thereafter, the patient began to decompensate requiring additional blood products and vasopressors. The decision was made for immediate operative intervention, which identified the bleeding Dieulafoy lesion (confirmed by histopathology) in the jejunum. DISCUSSION: Dieulafoy lesions are rare with an initial presentation of upper or lower GI bleeding, generally treated with endoscopic intervention. They are predominately found in the stomach or duodenum. When no clear source is identified by endoscopy, further diagnostic testing may be of value. Various imaging modalities exist; however, CT angiography or radionuclide scanning are particularly sensitive and can be beneficial in localizing the bleed when preparing for operative intervention. CONCLUSION: With advances in endoscopic techniques, surgical intervention is rarely performed for a Dieulafoy lesion. If endoscopy is unsuccessful, additional imaging can be obtained to localize the source of bleeding. However, in emergent cases, when additional imaging cannot be obtained due to lack of time or resources, adequate resection of the lesion should be performed for complete resolution of the disease process. Based on the case presentation and pathologic findings, this case provides further insight into Dieulafoy lesions and the rare need for surgical management.

Multi-origin mucinous neoplasm: Should we prophylactically remove the appendix in the setting of mucinous ovarian tumors?

INTRODUCTION: Tumors of the ovary and appendix have been well documented in the setting of pseudomyxoma peritonei (PMP) with constant debate over tumor origin. Generally, these tumors are found to have a single primary origin, most commonly the appendix, with metastatic spread to the ovaries. CARE PRESENTATION: Here we present a 61-year-old female who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) for a primary mucinous ovarian carcinoma. She presented to our institution one year later with abdominal pain and a palpable right lower quadrant mass, which on histopathologic exam was found to be a primary low grade mucinous appendiceal neoplasm (LAMN), alluding to the potential of two separate primary disease processes. DISCUSSION/CONCLUSION: With two primary, non-synchronous lesions, a thorough literature review suggests that during the patient's initial TAH-BSO, she could have additionally undergone an appendectomy. In doing so, this would provide accurate, complete staging and determine if the two neoplasms were truly primary in origin or metastatic. In addition, new genetic markers are being discovered, such as the Special AT-rich sequence-binding protein 2 (SATB2) marker, which has been found to be positive in those with a LAMN and negative in those with a primary mucinous ovarian carcinoma. By acquiring appropriate and complete staging we can better diagnose and treat these neoplasms.
