Background: Complementary to percutaneous intra-abdominal drainage, percutaneous transhepatic biliary drainage (PTBD) might ameliorate healing of pancreatic fistula and biliary leakage after pancreatoduodenectomy by diversion of bile from the site of leakage. This study evaluated technical and clinical outcomes of PTBD for this indication.
Methods: All patients undergoing PTBD for leakage after pancreatoduodenectomy were retrospectively evaluated in two tertiary pancreatic centers (2014-2019).
Background: Systemic autoimmunity can be present years before clinical onset of rheumatoid arthritis (RA). Adaptive immunity is initiated in lymphoid tissue where lymph node stromal cells (LNSCs) regulate immune responses through their intimate connection with leucocytes. We postulate that malfunctioning of LNSCs creates a microenvironment in which normal immune responses are not properly controlled, possibly leading to autoimmune disease.

The purpose of this study was to assess the clinical and imaging outcomes comparing conventional coiling and clipping of unruptured and ruptured MCA aneurysms.
Methods: We searched the electronic databases PubMed, EMBASE, and Cochrane from January 1990 to May 2014.
Article Synopsis
- A CT scan is now used instead of an ultrasound to quickly find fluid and injuries in patients with bad pelvic fractures.
- Researchers looked at CT scans from 160 patients to see how much fluid (small, moderate, or large) was present and if they needed surgery for bleeding.
- They found that having a moderate-to-large amount of fluid strongly suggests that surgery is needed to stop the bleeding.
Background: The sliding computed tomographic (CT) scanner in our trauma resuscitation room can be used early in the assessment of pelvic ring fracture patients. We determined the association between the presence of a pelvic blush on CT scan and the need for pelvic hemorrhage control (PHC). We hypothesized that many pelvic blushes found early in the resuscitation phase can be safely managed without intervention.

We examined the performance of FAST for detecting hemoperitoneum and predicting the need for intra-abdominal hemorrhage control in major pelvic fracture patients.
Methods: A 5-year retrospective study of major pelvic fracture patients was performed.
Article Synopsis
- The study tested a computer program to help doctors find blood clots in the lungs called pulmonary embolisms (PE) using CT scans.
- Six doctors with different levels of experience looked at 209 CT scans, first without the computer help and then with it, to see if it changed their ability to find PE.
- The computer program helped doctors find more cases of PE, but it took them a little longer to read the scans, increasing the time by about 22 seconds.
Purpose: To determine how many computed tomographic (CT) colonography training studies have to be evaluated by novice readers to obtain an adequate level of competence in polyp detection.
Materials And Methods: The study was approved by the Institutional Review Board. Informed consent was obtained from all participants.
