Early detection of biliary atresia (BA) has a vital role in prevention of liver cirrhosis in these patients. There are some evidences that triangular cord (TC) sign, i.e., triangular structure located cranial to the portal vein bifurcation on ultrasonographic examination, is suggestive of BA in suspected cases. The aim of this study is to evaluate and compare the sensitivity, specificity, and accuracy of TC sign with other methods of diagnosis such as hepatobiliary scan. ⋯ TC sign is more accurate than hepatobiliary scan and has acceptable sensitivity and specificity for diagnosis of BA.

Bacterial infections are common in cirrhosis and can lead to life-threatening complications. Sidestream dark-field (SDF) imaging has recently emerged as a noninvasive tool for capturing real-time video images of sublingual microcirculation in critically ill patients with sepsis. The objective of this study was to assess the utility of SDF in determining underlying infection in patients with cirrhosis. ⋯ This effect was restricted to small vessels only when Group B was compared with Group C. MFI<1.5 was found to have highest sensitivity (100%) and specificity (100%) for infection in decompensated cirrhosis. SDF imaging of sublingual microcirculation can be a useful bedside diagnostic tool to assess bacterial infection in cirrhosis.

Randomized Controlled Trial
Influence of preemptive analgesia on pulmonary function and complications for laparoscopic cholecystectomy.
Pain and diaphragmatic dysfunction are the major reasons for postoperative pulmonary complications after upper abdominal surgery. Preoperative administration of analgesics helps to reduce and prevent pain. The objective of this study was first to research the rate of pulmonary complications for laparoscopic cholecystectomy (LC) and then analyze the influence of preemptive analgesia on pulmonary functions and complications. ⋯ The overall incidence of atelectasia was similar for group 1 and 2 (30.2 vs. 29.2%). Although the degree of atelectesia was found to be more severe in the placebo group, the difference was not statistically significant. We concluded that although preemptive analgesia decreased the need for postoperative analgesia, this had no effect on pulmonary functions and pulmonary complications.

Review Meta Analysis
EUS-guided celiac plexus neurolysis for pain due to chronic pancreatitis or pancreatic cancer pain: a meta-analysis and systematic review.
The objective of this study was to evaluate the efficacy of EUS-guided CPN for pain relief in patients with chronic pancreatitis and pancreatic cancer. An initial search identified 1,439 reference articles, of which 130 relevant articles were selected and reviewed. Data was extracted from 8 studies (N = 283) for EUS-guided CPN for pain due to pancreatic cancer and nine studies for chronic pancreatitis (N = 376) which met the inclusion criteria. ⋯ In patients with pain due to chronic pancreatitis, EUS-guided CPN provided pain relief in 59.45% (95% CI = 54.51-64.30). In conclusion, EUS-guided CPN offers a safe alternative technique for pain relief in patients with chronic pancreatitis or pancreatic cancer. In patients with pain due to chronic pancreatitis, better techniques or injected materials are needed to improve the response.

Comparative Study
Wireless capsule motility: comparison of the SmartPill GI monitoring system with scintigraphy for measuring whole gut transit.
Assessment of whole gut transit, by radio-opaque markers or scintigraphy, is used to evaluate patients with constipation for slow gastrointestinal transit. Wireless capsule motility, using the SmartPill GI monitoring system, samples and transmits intraluminal pH, pressure, and temperature data from a capsule at regular intervals as it traverses through the gastrointestinal tract; from these, gastric emptying and whole gastrointestinal tract transit can be assessed. The objective of this study was to compare the SmartPill with whole gut transit scintigraphy to determine whether the SmartPill system could serve as a test for measurement of whole gut motility and transit. ⋯ SmartPill capsule assessment of gastric emptying and whole gut transit compares favorably with that of scintigraphy. Wireless capsule motility shows promise as a useful diagnostic test to evaluate patients for GI transit disorders and to study the effect of prokinetic agents on GI transit.
