BACKGROUND
Meconium ileus (MI) is defined as an intestinal obstruction caused by the impaction of inspissated meconium in the terminal ileum. In this study, we have evaluated the nonoperative management of patients of simple MI without fluoroscopic support -an important requisite of the Noblett's criteria. Besides this, surgical management in cases of failed conservative management and complicated MI was also assessed.
MATERIALS AND METHODS
This was a retrospective observational study. Various clinical and radiological parameters were evaluated. Conservative management included the use of water-soluble contrast diatrizoate meglumine and diatrizoate sodium. In case of nonpassage of meconium in 24 h from first intervention, exploratory laparotomy with ileostomy was performed. All complicated MI underwent exploratory laparotomy with creation of stoma as and when needed.
RESULTS
The duration of this study was 6½ years. Twenty-five neonates of MI were admitted. Of these, 22 had simple MI and remaining three had complicated MI. Eighteen neonates responded to the conservative management. In four neonates, who did not respond, exploratory laparotomy was performed. All three neonates having complicated MI underwent exploratory laparotomy. One patient expired in follow-up.
CONCLUSION
MI is an important neonatal emergency, which needed immediate attention of a pediatric surgeon. Proper evaluation of the patient, careful application of principals of conservative management, and timely surgical intervention may fetch satisfactory results.

Ehrlichia chaffeensis, a tick-transmitted rickettsial bacterium, is the causative agent of human monocytic ehrlichiosis. Biochemical characterization of this and other related Rickettsiales remains a major challenge, as they require a host cell for their replication. We investigated the use of an axenic medium for E. chaffeensis growth, assessed by protein and DNA synthesis, in the absence of a host cell. E. chaffeensis organisms harvested from in vitro cultures grown in a vertebrate cell line were fractionated into infectious dense-core cells (DC) and the non-infectious replicating form, known as reticulate cells (RC) by renografin density gradient centrifugation and incubated in the axenic medium containing amino acids, nucleotides, and different energy sources. Bacterial protein and DNA synthesis were observed in RCs in response to glucose-6-phosphate, although adenosine triphosphate, alpha-ketoglutarate or sodium acetate supported protein synthesis. The biosynthetic activity could not be detected in DCs in the axenic medium. While the data demonstrate de novo protein and DNA synthesis under axenic conditions for E. chaffeensis RCs, additional modifications are required in order to establish conditions that support bacterial replication, and transition to DCs.

The aim of the present study was to evaluate the prevalence and causes of spontaneous remission of obstructive jaundice in rats. Healthy male and female Wistar rats (180-220 g) were randomly assigned to receive common bile duct ligation (CBDL) and transection (group A), CBDL only (group B), or CBD dissection without ligation or transection (control group C; n=36 in each group). There was a difference in eye and skin jaundice prevalence between groups A and B from 14 days after surgery. The level of total bilirubin (TB) did not continue to increase in group A and began to decrease in the majority of rats in group B (P<0.05 vs. group B). At day 21 after surgery, the TB level returned to normal in group B and no significant difference was observed compared with group C. At day 21 after surgery, significant dilatation of bile ducts above the ligature was observed in group A following cholangiography with 38% meglumine diatrizoate and this contrast agent did not spread to other sites. Slight dilatation of the proximal bile ducts was observed in group B and the contrast agent entered the intestinal lumen through the omental ducts adhering to the porta hepatis. After 14 days of surgery, there were 36 rats in group A and B, and 17 rats exhibited spontaneous regression of jaundice. Overall, 47.2% (17/36) of rats experienced spontaneous remission of obstructive jaundice, 82.4% (14/17) of which underwent ligation only. The spontaneous remission of jaundice may have been caused by shunting through very small bile ducts or omental ducts adhering to the porta hepatis. If a model of biliary obstruction is to be established in future research, a model of CBDL and transection is preferable. In this case, jaundice reduction surgery should be performed 14 days after establishment of the model.

Clinical Trial
INTRODUCTION
Esophageal fistula is a serious and common complication of radiotherapy for esophageal cancer. Therefore, early diagnosis and treatment is necessary. Because of side effect of barium esophagography, it cannot be used to screening esophageal fistula during radiotherapy. Meglumine diatrizoate is an ionic contrast agent, its adverse reactions were rarely seen when it was used in the body cavity. The purpose of this trial is identified the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy.
METHODS/DESIGN
This trial was a prospective, multicenter, diagnostic clinical trial. A total of 105 patients with esophageal cancer will swallowed meglumine diatrizoate and underwent a radiographic examination weekly during radiotherapy, medical personnel observed the esophageal lesions to determine whether an esophageal fistula formed. If an esophageal fistula was observed, esophagofiberoscopy and/or computer tomography was used to further confirm the diagnosis. And the sensitivity and specificity of meglumine diatrizoate should be calculated for screening esophageal fistula during radiotherapy.
DISCUSSION
To our knowledge, this study protocol is the first to identify the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy. If oral meglumine diatrizoate can be used to screening esophageal fistula, more patients will benefit from early detection and treatment.

Review
BACKGROUND
Malignant bowel obstruction (MBO) is a common problem in patients with intra-abdominal cancer. Oral water soluble contrast (OWSC) has been shown to be useful in the management of adhesive small bowel obstruction in identifying patients who will recover with conservative management alone and also in reducing the length of hospital stay. It is not clear whether the benefits of OWSC in adhesive small bowel obstruction are also seen in patients with MBO.
OBJECTIVES
To determine the reliability of OWSC media and follow-up abdominal radiographs in predicting the success of conservative treatment in resolving inoperable MBO with conservative management.To determine the efficacy and safety of OWSC media in reducing the duration of obstruction and reducing hospital stay in people with MBO.
SEARCH METHODS
We identified studies from searching Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE in Process, Embase, CINAHL, Science Citation Index (Web of Science) and Conference Proceedings Citation Index - Science (Web of Science). We also searched registries of clinical trials and the CareSearch Grey Literature database. The date of the search was the 6 June 2017.
SELECTION CRITERIA
Randomised controlled trials (RCTs), or prospective controlled studies, that evaluated the diagnostic potential of OWSC in predicting which malignant bowel obstructions will resolve with conservative treatment.RCTs, or prospective controlled studies, that assessed the therapeutic potential of OWSC in managing MBO at any level compared with placebo, no intervention or usual treatment or supportive care.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed risk of bias and assessed the evidence using GRADE and created a 'Summary of findings' table.
MAIN RESULTS
We found only one RCT meeting the selection criteria for the second objective (therapeutic potential) of this review. This study recruited nine participants. It compared the use of gastrografin versus placebo in adult patients with MBO with no indication for further intervention (surgery, endoscopy) apart from standardised conservative management.The overall risk of bias for the study was high due to issues with low numbers of participants, selective reporting of outcomes and a high attrition rate for the intervention arm.Primary outcomesThe included trial was a pilot study whose primary outcome was to test the feasibility for a large study. The authors reported specifically on the number of patients screened, the number recruited and reasons for exclusion; this was not the focus of our review.Due to the low number of participants, the authors of the study decided not to report on our primary outcome of assessing the ability of OWSC to predict the likelihood of malignant small bowel obstruction resolving with conservative treatment alone (diagnostic effect). It also did not report on our primary outcome of rate of resolution of MBO in patients receiving OWSC compared with those not receiving it (therapeutic effect).The study reported that no issues regarding safety or tolerability of either gastrografin or placebo were identified. The overall quality of the evidence for the incidence of adverse events with OWSC was very low, downgraded twice for serious limitations to study quality (high risk of selective reporting and attrition bias) and downgraded once for imprecision (sparse data).Secondary outcomesThe study planned to report on this review's secondary outcome measures of length of hospital stay and time from administration of OWSC to resolution of MBO. However the authors of the study decided not to do so due to the low numbers of patients recruited. The study did not report on our secondary outcome measure of survival times from onset of inoperable MBO until death.
AUTHORS' CONCLUSIONS
There is insufficient evidence from RCTs to determine the place of OWSC in predicting which patients with inoperable MBO will respond with conservative treatment alone. There is also insufficient evidence from RCTs to determine the therapeutic effects and safety of OWSC in patients with malignant small bowel obstruction.

World Journal of Gastroenterology Dec 2017To assess the cleansing efficacy and safety of a new Colon capsule endoscopy (CCE) bowel preparation regimen. (Randomized Controlled Trial)
Randomized Controlled Trial
AIM
To assess the cleansing efficacy and safety of a new Colon capsule endoscopy (CCE) bowel preparation regimen.
METHODS
This was a multicenter, prospective, randomized, controlled study comparing two CCE regimens. Subjects were asymptomatic and average risk for colorectal cancer. The second generation CCE system (PillCam COLON 2; Medtronic, Yoqneam, Israel) was utilized. Preparation regimens differed in the 1 and 2 boosts with the Study regimen using oral sulfate solution (89 mL) with diatrizoate meglumine and diatrizoate sodium solution ("diatrizoate solution") (boost 1 = 60 mL, boost 2 = 30 mL) and the Control regimen oral sulfate solution (89 mL) alone. The primary outcome was overall and segmental colon cleansing. Secondary outcomes included safety, polyp detection, colonic transit, CCE completion and capsule excretion ≤ 12 h.
RESULTS
Both regimens had similar cleansing efficacy for the whole colon (Adequate: Study = 75.9%, Control = 77.3%; = 0.88) and individual segments. In the Study group, CCE completion was superior (Study = 90.9%, Control = 76.9%; = 0.048) and colonic transit was more often < 40 min (Study = 21.8%, Control = 4%; = 0.0073). More Study regimen subjects experienced adverse events (Study = 19.4%, Control = 3.4%; = 0.0061), and this difference did not appear related to diatrizoate solution. Adverse events were primarily gastrointestinal in nature and no serious adverse events related either to the bowel preparation regimen or the capsule were observed. There was a trend toward higher polyp detection with the Study regimen, but this did not achieve statistical significance for any size category. Mean transit time through the entire gastrointestinal tract, from ingestion to excretion, was shorter with the Study regimen while mean colonic transit times were similar for both study groups.
CONCLUSION
A CCE bowel preparation regimen using oral sulfate solution and diatrizoate solution as a boost agent is effective, safe, and achieved superior CCE completion.

Comparative Study Meta-Analysis Review
The objective of this systematic review is to identify key components of enhanced recovery protocols (ERP) that lead to improved length of hospital stay (LOS) following esophagectomy. Relevant electronic databases were searched for studies comparing clinical outcome from esophagectomy followed by a conventional pathway versus ERP. Relevant outcome measures were compared and metaregression was performed to identify the key ERP components associated with reduced in LOS. Thirteen publications were included, ERP was associated with no changes in in-hospital mortality, total complications, anastomotic leak, or pulmonary complications compared with a conventional pathway, however LOS was reduced in the ERP group. Metaregression identified that immediate extubation was associated with reduced LOS (OR = -0.51, 95%CI -0.77 to -0.25; P < 0.01). Several postoperative factors were associated with a significant reduction in length of hospital stay, and in order of most important were (i) gastrograffin swallow ≤5 days (OR = -4.27, 95%CI -4.50 to -4.03); (ii) mobilization on postoperative day ≤1 (OR = -2.49, 95%CI -2.63 to -2.34); (iii) removal of urinary catheter ≤2 days (OR = -0.99, 95%CI -1.15 to -0.84); (iv) oral intake with at least sips of fluid ≤1 day (OR = -0.96, 95%CI -1.24 to -0.68); (v) enteral diet with feeding jejunostomy or gastrostomy ≤ 1 day (OR = -0.57, 95%CI -0.80 to -0.35) and (vi) epidural removal ≤ 4 days (OR = -0.17, 95%CI -0.27 to -0.07). Several core ERP components and principles appear to be associated with LOS reduction. These elements should form a part of the core ERP for the specialty, while surgical teams incorporate other elements through an iterative process.

Post-mortem computed tomography (PMCT) and PMCT angiography (PMCTA) are rapidly becoming effective and practical methods in forensic medicine. In this article, the authors introduce a whole-body PMCTA approach involving left ventricle cardiac puncture. This procedure was performed in 9 males and 3 females. PMCT was performed first. Then a biopsy core needle was used for a percutaneous puncture into the left ventricle through the intercostal area under CT guidance. 1000 mL of contrast media (diatrizoate meglumine and normal saline [0.9%] at 1:2 ratio) was injected at a rate of 50 mL/8 s, followed by CT scan. Visualization of systemic arteries was achieved in 11 cases, while only partial visualization was achieved in 1 case, which may have been related to incomplete thawing of the cadaver. PMCTA results revealed no vascular diseases and abnormalities in 10 victims. Among the 10 victims, 4 post-scan autopsies were performed and found no vascular abnormalities, consistent with the PMCTA results. Autopsy of the other 6 victims were refused by the relatives. PMCTA revealed signs of internal carotid artery aneurysm inside the sphenoid sinus in one victim, which was confirmed by autopsy. PMCTA results of another victim showed signs of stenosis and blockage of the distal part of the right vertebral artery and basilar artery. Thromboembolism of those arteries was found during autopsy. Compared with other existing PMCTA methods for examination of vascular injuries and diseases, this technique involves simple procedures, is less time consuming, has lower associated costs, does not require specialized equipment, provides adequate imaging quality, and is suitable for centres not equipped with cardiopulmonary bypass machines or other specialized equipment.
