Operating on Jehovah's Witnesses: A Challenging Surgical Issue.

Blood transfusion is often utilized in surgery. Greece is the second-highest consumer of blood components in Europe. It has been shown that at least half of all transfusions are unnecessary and could be avoided. Jehovah's Witnesses (JWs) are a Christian religion that do not accept transfusion of whole blood or the four primary components of blood-namely, red blood cells, white blood cells, platelets, and plasma. This a retrospective study from September of 2015 to January of 2018, analyzing all JWs who underwent an elective operation at the Second Department of Propaedeutic Surgery in Laiko University Hospital. Twenty-nine (Rogers et al. in NCCN Guidelines Version 2.2014 Cancer- and Chemotherapy-Induced Anemia. NCCN Clinical Practice Guidelines in Oncology. National Comprehensive Cancer Network, Fort Washington, 2013) JW patients, 23 females (74.1%) and eight males, were operated on during the aforementioned period. The median ASA score was 1 (range 1-3), and only two of the patients needed postoperative monitoring in the ICU. Almost half of the patients (45.1%) needed iron infusion and EPO injection preoperatively. Two patients presented with postoperative complications, with no postoperative deaths. In conclusion, we found that surgery, in our small group of JW patients, was safe and successful despite the lack of blood transfusion. Techniques developed to treat JW patients should be more widely used to improve clinical outcomes and reduce costs to the healthcare system.

Entero-vesical fistulas in CROHN'S disease: A case series report and review of the literature.

BACKGROUND: Entero-vesical fistula (EVF) is an abnormal link between the enteric lumen and the urinary bladder. Crohn's disease (CD) represents, nowadays, the most common cause in the formation of this fistula. MATERIALS AND METHODS: The aim of this study was to describe the diagnostic and treating modalities applied in nine patients with CD and EVFs, the clinical/epidemiological features of this clinical entity and to perform a systemic review of the literature, concerning the diagnosis and treatment of this complication. RESULTS: The medical records of eight men and one woman (mean age 42 ± 12 years) with EVFs were analyzed. The terminal ileum and the ileocecal region were affected in three and six cases, respectively. The most common symptoms were pneumaturia, fecaluria, fever, urinary urgency and abdominal pain. The diagnosis was suspected by abdominal CT scan and by indirect findings of bladder infection in cystoscopy. MRI with concurrent cystography set the diagnosis in three patients. Colonoscopy was not helpful. Conservative treatment, including administration of antibiotics and immunosuppressive agents in all patients and anti-TNF-a agent (infliximab) in six patients, was ineffective. Surgical treatment was applied in seven cases (77.8%), including fistula repair in all patients, drainage of coexistent intraabdominal abscess in two, small bowel resection in four and ileocecectomy in two cases. CONCLUSION: EFVs are uncommon but potentially dangerous complications of CD. Abdominal CT scan and cystoscopy are the most commonly used diagnostic modalities. Surgical treatment seems to be unavoidable in most cases, although medical treatment could also benefit a small cohort of patients.
