Use of telecytology for the immediate assessment of CT guided and endoscopic FNA cytology: Diagnostic accuracy, advantages, and pitfalls†

Telecytology (TC) can assist cytopathologists in efficiently providing immediate evaluation for fine needle aspirations (FNAs) performed at remote locations. Our aim was to evaluate the accuracy and feasibility of TC for immediate assessments of FNAs. Phase I: Diff‐Quik and Pap stained smears from two retrospective sets of 20 pilot cases each (n = 40) were included for TC assessments. For the first set, diagnoses were rendered by four pathologists and for the second set, in addition, four cytotechnologists also participated. Diagnostic concordance with the final diagnosis was assessed. Phase IIA: These were followed by real time assessments (RTA) of 56 TC FNAs and diagnostic concordance was compared to that of 100 conventional in‐person immediate assessments (Phase IIB).

BackgroundBronchogenic cysts are rare foregut abnormalities that arise from aberrant budding of the tracheobronchial tree early in embryological development. These cysts predominantly appear in the mediastinum, where they may compress nearby structures. Intra-abdominal bronchogenic cysts are rare. We report an intra-abdominal bronchogenic cyst that was excised laparoscopically.MethodsA 40-year old female with a history of gastritis presented for evaluation of recurrent abdominal pain. A previous ultrasound showed cholelithiasis and a presumed portal cyst. Physical examination and laboratory findings were unremarkable. A CT scan with pancreatic protocol was performed and an intra-abdominal mass adherent to the esophagus was visualized. A laparascopic enucleation of the mass was performed. A 3-cm myotomy was made after circumferential dissection of the cyst and the decision was made intraoperatively to reapproximate the muscularis layer. A PubMed literature search on surgical management of esophageal bronchogenic cysts was subsequently performed.ResultsThe literature search performed on the subject of esophageal bronchogenic cysts found one review article focusing on intramural esophageal bronchogenic cysts in the mediastinum and five case reports of esophageal bronchogenic cysts. Of these, only one was both intraabdominal and managed laparascopically with simple closure of the resulting myotomy. The majority of the bronchogenic cysts mentioned in the literature were located mediastinally and were managed via open thoracotomy. Our findings confirm the rarity of this particular presentation and the unique means by which this cyst was surgically excised.ConclusionThis case highlights the management of a rare entity and advocates for enucleation of noncommunicating, extraluminal esophageal bronchogenic cysts and closure of the esophageal muscular layers over intact mucosa as a viable surgical approach to this unusual pathology. Other cases of laparascopic enucleation of bronchogenic cysts have shown similarly uneventful postoperative courses and rapid recovery with no apparent return of symptoms.
