In vivo measurement of esophageal hiatus surface area using MDCT: description of the methodology and clinical validation

Moten, Ambria S; Ouyang, Wei; Hava, Sana; Zhao, Huaqing; Caroline, Dina; Abbas, Abbas; Dass, Chandra
PURPOSE/OBJECTIVE:Accurate estimation of esophageal hiatus surface area (HSA) prior to surgical repair of hiatal hernia is difficult. The ability to do so may assist with following progression of hiatal hernias, choosing the optimal surgical approach and post-surgical evaluation. We developed a method for measurement of HSA using multi-planar reconstruction (MPR) of multi-detector computed tomography (MDCT) scans and sought to validate our method using intra-operative HSA measurements. METHODS:Patients with thoracic or abdominal CT scans who were scheduled to undergo hiatal hernia repair were identified. A radiologist performed MPR of each MDCT scan to obtain the measured HSA (mHSA). Estimated HSA (eHSA) was obtained using intra-operative measurements of crura length and distance between crural edges. The association between eHSA and the corresponding mHSA was assessed using Pearson correlation. The intra-class correlation coefficient was calculated to assess both intra-observer and inter-observer agreement for the MDCT-MPR technique. RESULTS:based on CT measurements. The correlation coefficient for eHSA and corresponding mHSA was 0.83 (p < 0.001). The intra-class correlation coefficient was 0.97 (p < 0.001) for intra-observer agreement and 0.97 (p < 0.001) for inter-observer agreement. CONCLUSION/CONCLUSIONS:We developed a MDCT-MPR technique that measures HSA in vivo. This technique is reproducible and can be used for pre-operative planning and post-operative follow-up of patients with symptomatic hiatal hernia.

Gastric emptying scintigraphy results may influence the selection of the type of bariatric surgery: A cohort study

Khiyani, Neeraj; Tulchinsky, Mark; Hava, Sana; Ho, Truong An; Dadparvar, Simin
Bariatric surgery (BAS) may result in adverse outcomes that include appearance of gastrointestinal (GI) symptoms and/or failure to reach the weight reduction goal. This retrospective study tested the hypothesis that pre-operative gastric emptying (GE) abnormality is responsible for adverse post-surgical outcomes.Pre-operative GE was performed using the standard solid-meal GE scintigraphy (GES) in 111 consecutive patients (105 females and 6 males, mean age 46.2 years, range 20-70 years) who were evaluated for BAS. All underwent BAS - 93 had laparoscopic sleeve gastrectomy (LSG) and 18 had Roux-en-Y (ReY) gastric bypass. All had short-term (3-6 months) and long-term (up to 54 months) follow-up with review of symptoms, physical, and laboratory examinations. Chi-square analysis was performed. P-value < .05 was considered significant.Of the 111 patients, 83 had normal and 28 had abnormal pre-op GES. Sixty-eight were asymptomatic and 43 were symptomatic prior to surgery. Following surgery, 81 patients were asymptomatic and 30 were symptomatic at long-term follow-up. There was no significant difference between pre-op GE results and post-surgical adverse clinical outcome (p = ns). However, GES results seem to have guided the selection of surgical procedure significantly (P = .008).Pre-operative GE study was not a strong predictor of clinical outcome in BAS. Although, it influenced the type of surgery, as when the GES was abnormal, the patient was more likely to undergo ReY and when GES was normal, they favored LSG. Interestingly, many of our symptomatic patients at 6 months post-op were asymptomatic after long-term follow-up.

Rosai-Dorfman disease of the breast: A potential marker of systemic disease [Case Report]

Goldbach, Alyssa R; Hava, Sana; Caroline, Dina; Zhao, Xiaofeng; Bains, Ashish; Pascarella, Suzanne
Rosai-Dorfman disease (RDD) is a rare idiopathic benign proliferative disorder of histiocytes. RDD typically presents with cervical lymph node involvement; however, extranodal sites such as the breast can also be involved and should prompt evaluation for additional sites of disease.

Utilizing Audience Response to Foster Evidence-based Learning in a Pilot Study: Does It Really Work?

Awan, Omer; Dako, Farouk; Akhter, Talal; Hava, Sana; Shaikh, Faiq; Ali, Sayed; Chang, Paul
Introduction Radiology residency programs are increasingly using audience response systems (ARS) in educational lectures. It is imperative that this is investigated to assess if learning outcomes in trainees are actually improved. Methods The primary objective of this randomized prospective unblinded pilot study was to assess the effect of ARS on long-term learning outcomes, with a secondary objective of understanding perceptions of ARS amongst radiology residents. Twenty-two radiology residents were randomized into two groups of 11 residents each receiving five identical musculoskeletal (MSK) radiology lectures. One group received lectures through ARS and the other through traditional didactics. A pretest and identical posttest were completed by all residents at baseline and eight months later, respectively. Residents also completed a pre and post five-question Likert scale survey designed to measure perceptions of ARS. Results Wilcoxon rank sum tests revealed no statistically significant difference between the two groups of residents on the pretest (p = 0.47) or the posttest (p = 0.41). Of the five questions designed to gauge perceptions of ARS, "How often do you study radiology outside of work?" resulted in statistical significance between groups after the lecture series via ordinal logistic regression, with the ARS group six times more likely to study compared to the non-ARS group (Odds ratio = 6.52, P = 0.04, 95% Confidence Interval [1.1, 38.2]). There was no statistical difference in response to this question prior to the lecture series. Discussion Use of ARS was associated with increased likelihood of studying radiology without significant difference in long-term learning outcomes.

IUD embedment in the fallopian tube: An unexpected location for a translocated IUD [Case Report]

Goldbach, Alyssa R; Hava, Sana; Patel, Harshad; Khan, Mansoor
Intrauterine devices (IUDs) are the most common form of contraceptive used worldwide. The imaging features of IUDs and their potential complications are crucial to recognize in order to determine adequate positioning and ultimately function of the IUD. Herein, we report a rare case of a copper IUD embedded in the left fallopian tube that required surgical removal. Only a few such cases have been reported in the literature to date.
