Identifying Gender Barriers for Colorectal Cancer Screening and Assessing the Need for a Multigender Endoscopy Team: A Prospective Multicenter Study.

INTRODUCTION: Gender preferences have been reported as a barrier to colorectal cancer screening, particularly among women. We aim to identify the role of patients' gender preferences for endoscopists and endoscopy team members, with the effect of age-related and regional differences. METHODS: We conducted an anonymous, voluntary survey of all adult outpatients presenting at our endoscopy centers before their procedures. RESULTS: We received 2,138 (1,207 women, 905 men, and 26 undisclosed; 50% urban and 50% rural) completed surveys. The majority of the patients (89%) did not have an endoscopist gender preference, while 8% preferred a same-gender endoscopist, and 2% preferred an opposite gender endoscopist. Among patients who expressed a gender preference, men more commonly preferred a same-gender endoscopist than women (91% vs 67%, P < 0.05). More patients preferred a same-gender endoscopy team member than a same-gender endoscopist (17% vs 8%, P < 0.05), and women more commonly preferred a same-gender endoscopy team member than men (26% vs 6%, P < 0.05). Most patients who expressed same-gender endoscopist preference were between the ages of 50-69 years as compared to other age groups (P < 0.05). Of the urban patients, 9% expressed a same-gender endoscopist preference and 3% expressed an opposite gender preference, compared with 7% and 2% of rural patients (P < 0.05). Among patients with any endoscopist gender preference, rural patients were more willing to wait longer (41% vs 21%, P < 0.05), whereas urban patients were willing to pay more (64% vs 14%, P < 0.05) to have their preferences met. DISCUSSION: Contrary to previous studies, most patients did not have an endoscopist gender preference. Interestingly, men had more same-gender endoscopist preference, whereas women had more same-gender endoscopy team member preference. Age-related and regional differences exist among patients' gender preferences for their endoscopist and endoscopy team member, and addressing these preferences while creating an environment of a multigender endoscopy team may be beneficial in improving colorectal cancer screening.

Heads or tails: confusion about "proximal" and "distal" terminology for pancreaticobiliary anatomy.

BACKGROUND AND STUDY AIMS: The anatomical meaning of the terms "proximal" and "distal" in relation to the pancreaticobiliary anatomy can be confusing. We aimed to investigate practice patterns of use of the terms "proximal" and "distal" for pancreaticobiliary anatomy amongst various medical specialties. MATERIALS AND METHODS: An online survey link to a normal pancreaticobiliary diagram was emailed to a multispecialty physician pool. Respondents were asked to label various parts of the common bile duct (CBD) and pancreatic duct (PD) using the terms "proximal," "distal," "not sure," or "other." Variability in use of these terms between specialties was assessed. RESULTS: We received 370 completed surveys from 182 gastroenterologists (49.2 %), 97 surgeons (26.2 %), 68 radiologists (18.4 %), and 23 other physicians (6.2 %). There was overall consensus in describing the upper/sub-hepatic CBD as "proximal CBD" (73.8 %, P  = 0.1499) and the lower/pre-ampullary portion as "distal CBD" (84.6 %, P  = 0.1821). CONCLUSIONS: Although use of the terms "proximal" and "distal" is still very common to describe pancreaticobiliary anatomy, there is a discordance about its meaning, particularly for the PD. Use of descriptive terminology may be a more accurate alternative to prior ambiguous terminologies such as "proximal" or "distal" and can serve to improve communication and decrease the possibility of medical errors.

Conscious or unconscious: the impact of sedation choice on colon adenoma detection.

AIM: To determine if anesthesiologist-monitored use of propofol results in improved detection of adenomas when compared with routine conscious sedation. METHODS: This retrospective study was conducted at two separate hospital-based endoscopy units where approximately 12,000 endoscopic procedures are performed annually, with one endoscopy unit exclusively using anesthesiologist-monitored propofol. Three thousand two hundred and fifty-two patients underwent initial screening or surveillance colonoscopies. Our primary end point was the adenoma detection rate, defined as the number of patients in whom at least one adenoma was found, associated with the type of sedation. RESULTS: Three thousand two hundred and fifty-two outpatient colonoscopies were performed by five selected endoscopists. At least one adenoma was detected in 27.6% of patients (95% CI = 26.0-29.1) with no difference in the detection rate between the anesthesiologist-propofol and group and the gastroenterologist-midazolam/fentanyl group (28.1% vs 27.1%, P = 0.53). CONCLUSION: The type of sedation used during colonoscopy does not affect the number of patients in whom adenomatous polyps are detected.

Colonoscopy in the diagnosis and management of diverticular disease.

This review examines the role of colonoscopy in the evaluation of asymptomatic diverticulosis, segmental diverticular disease-associated colitis and acute diverticulitis. Asymptomatic acute diverticulitis, discovered during screening colonoscopy, is also discussed. In addition, the use of colonoscopy, both diagnostic and therapeutic, is compared to standard radiology studies for the management of acute diverticular bleeding.

Factors associated with time to laparoscopic cholecystectomy for acute cholecystitis.

AIM: To determine patient and process of care factors associated with performance of timely laparoscopic cholecystectomy for acute cholecystitis. METHODS: A retrospective medical record review of 88 consecutive patients with acute cholecystitis was conducted. Data collected included demographic data, co-morbidities, symptoms and physical findings at presentation, laboratory and radiological investigations, length of stay, complications, and admission service (medical or surgical). Patients not undergoing cholecystectomy during this hospitalization were excluded from analysis. Hierarchical generalized linear models were constructed to assess the association of pre-operative diagnostic procedures, presenting signs, and admitting service with time to surgery. RESULTS: Seventy cases met inclusion and exclusion criteria, among which 12 were admitted to the medical service and 58 to the surgical service. Mean +/- SD time to surgery was 39.3 +/- 43 h, with 87% of operations performed within 72 h of hospital arrival. In the adjusted models, longer time to surgery was associated with number of diagnostic studies and endoscopic retrograde cholangio-pancreatography (ERCP, P = 0.01) as well with admission to medical service without adjustment for ERCP (P < 0.05). Patients undergoing both magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) scans experienced the longest waits for surgery. Patients admitted to the surgical versus medical service underwent surgery earlier (30.4 +/- 34.9 vs 82.7 +/- 55.1 h, P < 0.01), had less post-operative complications (12% vs 58%, P < 0.01), and shorter length of stay (4.3 +/- 3.4 vs 8.1 +/- 5.2 d, P < 0.01). CONCLUSION: Admission to the medical service and performance of numerous diagnostic procedures, ERCP, or MRCP combined with CT scan were associated with longer time to surgery. Expeditious performance of ERCP and MRCP and admission of medically stable patients with suspected cholecystitis to the surgical service to speed up time to surgery should be considered.

Mycophenolate mofetil for drug-induced vanishing bile duct syndrome.

Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil.
