Optimization of pineapple juice amount used as a negative oral contrast agent in magnetic resonance cholangiopancreatography

To evaluate the potential variability of Manganese (Mn2+) in commercial pineapple juice (PJ) produced in different years and to identify the optimal Mn2+ concentration in the correct amount of PJ to be administered prior to Magnetic Resonance Cholangiopancreatography (MRCP) in order to suppress the gastroduodenal (GD) liquid signal. The Mn2+ concentration in PJ produced in different years was defined using Atomic Absorption Spectrometry. The optimal Mn2+ concentration and the amount of PJ, were estimated in an in-vitro analysis, and were then prospectively tested in a population of patients who underwent MRCP. The results were compared with those achieved with the previous standard amount of PJ used in a similar population. The concentrations of Mn2+ in commercial PJ produced in different years did not differ. A total amount of 150 ml (one glass) of PJ having a high Mn2+ content (2.37 mg/dl) was sufficient for the suppression of the GD liquid signal, despite the additional dilution caused by GD liquids since it led to a final concentration of Mn2+ of 0.5–1.00 mg/dl. The optimized single-dose oral administration of 150 ml (approximately one glass) of PJ having a high Mn2+ concentration prior to MRCP was adequate to guarantee the correct amount of Mn2+ to suppress the GD signal.

Is Oral Contrast Beneficial for Visualization of the Appendix in Low-Weight Children?Les produits de contraste par voie orale sont-ils utiles pour visualiser l’appendice chez les enfants de petit poids?

Purpose: It has been shown that oral contrast does not improve the diagnostic accuracy of Computed Tomography (CT) for appendicitis in pediatric patients; however, the cohorts in these studies were not stratified by weight or body mass index. The purpose of this study is to assess the benefit of oral contrast administration for identifying the appendix in younger children in the lower weight quartile. Materials and Methods: This retrospective study comprised 100 patients (2–10 years) in lower weight quartile who had intravenous contrast-enhanced CT of the abdomen and pelvis, 37 of which with oral contrast, and 63 without. A pediatric radiologist and a pediatric radiology fellow independently assessed whether the appendix was visualized or not. In case of discrepancy, an additional pediatric radiologist was the “tie-breaker.” Chi-squared test was used to compare the proportion of visualized appendix between the groups (with and without oral contrast). Inter-rater reliability was determined using Cohen’s Kappa coefficient. Results: There was no significant difference in the visualization of the appendix between the group with oral contrast and without ( P = 1). The Cohen Kappa coefficients were .33 (.05, .62) and .91 (.73, 1.00) for the “no oral” and “oral” groups, respectively, yielding evidence of a difference ( P = .007). Conclusions: There was no significant difference in the visualization of the appendix using CT with or without oral contrast in low-weight pediatric patients. The inter-rater reliability, however, was significantly higher in the group given oral contrast. Additional studies assessing the value of oral contrast for the sole indication of appendicitis may provide clearer results.

Spontaneous drainage of the pseudocyst of the tail of the pancreas with the formation of a junction between the cyst and the stomach

The aim of the study was to evaluate the informative value of various diagnostic methods for spontaneous drainage of the pancreatic pseudocyst into the stomach.Materials and methods: based on the clinical observation of a patient who received complaints of pain in the epigastrium, an episode of melena, after suffering acute pancreatitis several years ago with the development of pancreatic necrosis with an outcome in the cyst of the tail of the pancreas, drainage of the omentum bag. The patient underwent a comprehensive laboratory and instrumental examination.Results: ultrasound, endoscopic examination, MSCT suspected a malignant process in the stomach with ulceration and germination into the pancreas. After performing endoscopic ultrasonography, it was possible to differentiate the layers of the formation and make the correct diagnosis, which was confirmed by subsequent MSCT with oral contrast.Conclusions: a spontaneously opened pancreatic pseudocyst in the lumen of the stomach is a rare and difficult to diagnose disease. An integrated approach, including endoscopic, ultrasound, X-ray, and laboratory methods of investigation when compared with the clinical picture, allows us to verify the formation of the pancreas.

Computed tomography in intestinal obstruction: a tertiary care perspective from Northern India

Background: Intestinal obstruction is a very common surgical emergency faced today in surgical ERs (emergency rooms) all around the globe. With the advent of newer technology, management of intestinal obstruction has changed significantly. Today computed tomography (CT) employs both intravenous as well as oral contrast for determining the cause and the level of obstruction. It also gives additional information regarding any malignancy causing the obstruction, its staging and status of vessels. Thus, a surgeon can go in the procedure with a plan already in mind which can be discussed in detail with experienced surgeons beforehand.Methods: This was a prospective observational study that was done in department of surgery at GMC Jammu over a period of two years. Patients of intestinal obstruction who presented to our department were enrolled in this study. They were subjected to a contrast enhanced CT after due preparation and managed accordingly. Data was recorded in a tabulated fashion and evaluated.Results: After implementing the exclusion criteria’s, a total of 163 patients were included in this study, majority being males in the age group of 20-40 years. Major cause of intestinal obstruction was attributed to post-operative adhesions followed by band obstruction due to various cause. CT findings were seen to be quite significant in evaluation and management of intestinal obstruction. About 30 % of the patients enrolled in our study were treated conservatively while 70 % required operative intervention in form of exploratory laparotomy.Conclusions: Computed tomography is widely available now a days at a cheaper cost. It greatly increases the armamentarium of the surgeon in dealing with this condition. A lot many cases today are dealt conservatively due to high utilisation of CT scan. It also helps the surgeon to preoperatively plan a proper surgical approach

Slippage of Gastric Banding for Mobid Obesity: case report and review of literature

Background: laparoscopic adjustable gastric banding (LABG) remains the commonest and less invasive bariatric operation. It has many advantages in the treatment of obesity and is associated with low morbidity and mortality rates.When it happens a Gastric Band Slippage (GBS), part of the gastric fundus herniates through the band. Removal of GB is necessary to prevent necrosis of the herniated stomach.Case report: We present a case of a 40-year-old female patient who was admitted for a huge gastric pouch dilatation after 3 years of underwent LAGB.Conclusion: The LAGB is one of the most common procedures used for the treatment of morbid obesity. The complications are generally not mortal but it is necessary that complications have been recognized by general surgeon and physicians should be aware of the symptoms. Diagnosis of GBS can be made with signs or symptoms and patient’s medical history, with the use of oral contrast X-ray studies or CT Scan and surgical intervention is necessary.

P-OGC88 Is Routine Contrast Swallow after Ivor-Lewis Oesophagectomy Required or Justified?

Background Traditionally many Upper-GI cancer tertiary centres have carried out contrast swallow fluoroscopic studies as a routine after Ivor-Lewis “Two-Stage” Oesophagectomy. However, more recently studies have demonstrated the limited value of this test as a routine screening study. The primary outcome of our study was to assess the sensitivity of routine contrast swallow in identifying anastomotic leak post oesophagectomy and identify how the study changed management of these patients. Methods This was a single-centre retrospective study involving 2-observer data collection. Data was collected and analysed from clinical notes for all patients who underwent an Ivor-Lewis oesophagectomy for cancer between January 2011 to December 2020. Results A total of 220 patients were identified. Protocol at the centre was to obtain a routine contrast swallow in the Fluoroscopy department on the fifth post-operative day– which occurred in 211 patients (96%). A total of 19 (8.64%) patients were diagnosed with an anastomotic leak (clinically and/or radiologically), with contrast swallow imaging and/or computed tomography (CT). There was no correlation between incidence of leak and T stage (p = 0.38) and N staging (p = 0.22). Only 3 of 19 anastomotic leaks were positively identified on contrast swallow study. All patients with anastomotic leak identified by contrast swallow study were asymptomatic i.e. “subclinical”. 2 patients were managed conservatively; one underwent endoscopic stent insertion. CT scan with oral contrast was the mode of diagnosis for 16 anastomotic leaks; where 10 patients underwent a CT scan following a normal contrast swallow study due to suspicious symptoms and 6 patients underwent expedited CT scans prior to Day-5 contrast swallow study due to presence of symptoms and limitation of fluoroscopy resources. The sensitivity of the Day-5 contrast swallow study was calculated to be 15.8% (CI 3.4, 39.6) with a specificity of 98.0% (CI 95.0, 99.5). Conclusions Our data reflects that routine contrast swallow study on Day-5 post Ivor-Lewis esophagectomy has a poor sensitivity in detecting anastomotic leak and may be falsely reassuring. The vast majority of patients had no change in management as a result of contrast swallow. This adds to the growing body of evidence limiting the role of contrast swallow in this situation. We recommend that clinical judgement and use of CT and endoscopy be the surgeon’s prime tools in the diagnosis of anastomotic leak post oesophagectomy.

Pneumatosis cystoides intestinalis in a trauma patient presenting with pneumoperitoneum: a case report

Background Pneumatosis cystoides intestinalis is a rare and usually benign condition in which multiple thin-walled cysts develop in the submucosa or subserosa of the gastrointestinal tract. While usually asymptomatic, severe cases can result in pneumoperitoneum, which can be managed surgically or medically depending on circumstances. We present a case of a patient with pneumatosis cystoides intestinalis, which presented as pneumoperitoneum following trauma. To our knowledge, there are no other published cases in which a trauma patient with pneumoperitoneum was found to have radiologic evidence of pneumatosis cystoides intestinalis. Case presentation We present the case of a 37-year-old Hispanic male admitted to the hospital after being involved in a motorcycle accident. Computed tomography imaging of the abdomen and pelvis with oral and intravenous contrast demonstrated trace pneumoperitoneum, possibly originating from the splenic flexure of the colon without evidence of extravasation of oral contrast. Laparoscopy with conversion to exploratory laparotomy revealed bowel abnormalities at the distal transverse colon and splenic flexure, which were identified as pneumatosis cystoides intestinalis by pathology. There was no evidence of bowel perforation. A panel of abdominal radiologists attended the computed tomography interpretation to note that incidental atraumatic or traumatic rupture of the cysts could have caused the pneumoperitoneum. The patient had an uncomplicated postoperative course and was transferred to another facility per insurance request. Conclusions When presenting in the context of trauma, pneumatosis cystoides intestinalis can lead to difficult management decisions. To our knowledge, there are no existing evidence-based guidelines for the scenario of concurrent pneumatosis cystoides intestinalis, blunt abdominal trauma, and pneumoperitoneum in a patient with a benign abdominal exam. This patient’s pneumoperitoneum was likely caused by rupture of preexisting cysts rather than frank bowel perforation. Patients who are asymptomatic, lack signs of clinically worrisome disease, and have a low pretest probability will likely not benefit from surgery and can be medically managed. Thorough discussion between surgeons and radiologists can be helpful when evaluating the clinical significance of a patient’s pneumatosis cystoides intestinalis and aid in the decision to perform surgery.

Evaluating suspected small bowel obstruction with the water-soluble contrast challenge

With optimized technique, the water-soluble contrast (WSC) challenge is effective at triaging patients for operative versus non-operative management of suspected small bowel obstruction (SBO). Standardized study structure and interpretation guidelines aid in clinical efficacy and ease of use. Many tips and tricks exist regarding technique and interpretation, and their understanding may assist the interpreting radiologist. In the future, a CT-based WSC challenge, utilizing oral contrast given as part of the initial CT examination, might allow for a more streamlined algorithm and provide more rapid results.
