  • SAGES Clinical Spotlight Review: Intraoperative Cholangiography
    SAGES Clinical Spotlight Review: Intraoperative cholangiography William W. Hope, MD, Robert Fanelli MD, Danielle S. Walsh MD, Ray Price MD, Dimitrios Stefanidis MD, William S. Richardson MD, and the SAGES Guidelines Committee Preamble The following clinical spotlight review regarding the intraoperative cholangiogram is intended for physicians who manage and treat gallbladder/biliary pathology and perform laparoscopic cholecystectomy. It is meant to critically review the technique of intraoperative cholangiography, alternatives for intraoperative biliary imaging, and the available evidence supporting their safety and efficacy. Based on the level of evidence, recommendations may or may not be given for their use in clinical practice. Disclaimer Guidelines for clinical practice and spotlight reviews are intended to indicate preferable approaches to medical problems as established by experts in the field. These recommendations will be based on existing data or a consensus of expert opinion when little or no data are available. Spotlight reviews are applicable to all physicians who address the clinical problem(s) without regard to specialty training or interests, and are intended to convey recommendations based on a focused topic; within the defined scope of review, they indicate the preferable, but not necessarily the only acceptable approaches due to the complexity of the healthcare environment. Guidelines and recommendations are intended to be flexible. Given the wide range of specifics in any health care problem, the surgeon must always choose the course best suited to the individual patient and the variables in existence at the moment of decision. Guidelines, spotlight reviews, and recommendations are developed under the auspices of the Society of American Gastrointestinal Endoscopic Surgeons and its various committees, and approved by the Board of Governors.

  • Impact of Preoperative Endoscopic Ultrasound in Surgical Oncology
    REVIEW Impact of preoperative endoscopic ultrasound in surgical oncology Endoscopic ultrasound (EUS) has a strong impact on the imaging and staging of solid tumors within or in close proximity of the upper GI tract. Technological developments during the last two decades have increased the image quality and allowed very detailed visualization of local tumor spread and lymph node affection. Current indications for EUS of the upper GI tract encompass the differentiation between benign and malignant lesions, the staging of esophageal, gastric and pancreatic cancer, and the procurement of a biopsy specimen through fine-needle aspiration. Various technical innovations during the past two decades have increased the diagnostic quality and have simultaneously strengthened the role of EUS in the clinical setting. This article will give a compressed summary on the current state of EUS and possible further technical developments. 1 KEYWORDS: 3D imaging elastosonography endoscopic ultrasound miniprobes Sascha S Chopra & oncologic surgery Michael Hünerbein† 1Department of General & Transplantation Surgery, Charité Campus Virchow-Clinic, Berlin, Conventional endoscopic ultrasound the so-called ‘miniprobes’ into the biliary system Germany Linear versus radial systems or the pancreatic duct in order to obtain high-res- †Author for correspondence: Department of Surgery & Surgical Endoscopic ultrasound (EUS) with flex- olution radial ultrasound images locally.

  • Is Intravenous Cholangiography an Alternative to the Routine Per-Operative Cholangiogram? Simon P.J
    Postgraduate Medical Journal (1989) 65, 896 - 899 Postgrad Med J: first published as 10.1136/pgmj.65.770.896 on 1 December 1989. Downloaded from Is intravenous cholangiography an alternative to the routine per-operative cholangiogram? Simon P.J. Huddy and John A. Southam Epsom District Hospital, Dorking Road, Epsom, Surrey, UK Summary: Ultrasonography, although an accurate method ofdetecting stones within the gall bladder, is unreliable for the detection of bile duct stones for which per-operative cholangiography remains the standard investigation. Fifty seven patients undergoing elective cholecystectomy had both a pre-operative intravenous cholangiogram and per-operative cholangiography. The pre-operative investigation is shown to be at least as effective in the detection of common bile duct stones and only missed a duct stone in one patient. The substitution of pre-operative intravenous cholangiography for routine per-operative cholangiography would result in a significant reduction in operating time, may provide advance knowledge on the biliary anatomy and would allow advance planning of the likely procedure. It is suggested that pre-operative intravenous cholangiography, carried out on the day of admission, should be considered as a preferred alternative investigation to per-operative cholangiography. Introduction Protected by copyright. Per-operative cholangiography, first introduced by An intravenous cholangiogram was performed as Mirizzi in 1932,' is now a commonly performed an outpatient procedure before admission for procedure. It is considered by many authorities to be cholecystectomy.
