ABSTRACT
Orogastric tubes (OGTs) are frequently used to administer feeds and medications to critically ill patients. They are inserted blindly, with a low first-pass success rate and frequent benign complications. OGT fractures and ingestion are exceedingly rare, with only two cases reported to date. Herein, we describe a rare case of OGT transection and ingestion in a male patient admitted for hyperacute delirium and complicated pneumonia. The OGT remnant was retrieved using an endoscope without any complications. Clinicians must be aware of this rare but potentially catastrophic complication of OGT use. OGTs must be inspected in the same manner as endotracheal tubes to ensure patient safety.
ABSTRACT
OBJECTIVE: To assess the diagnostic accuracy of haematoxylin-eosin staining in clinically suspected Hirschsprung disease, and to compare the findings with calretinin and S100 immunohistochemistry. METHODS: The retrospective study was conducted at the AL-Khansaa Teaching Hospital, Nineveh, Iraq, and comprised data from January 2017 to October 2020 of rectal suction biopsies of patients with clinically and radiologically suspected Hirschsprung disease. Histopathology and immunohistochemistry were performed. Data was analysed using SPSS 16. RESULTS: Of the 114 patients, 74(64.9%) were males and 40(35.1%) were females. Based on histology, 28(24.6%) cases were negative for ganglion cells, and, of them 25(89.2%) revealed nerve bundle hypertrophy. The diagnostic accuracy for the detection of ganglion cell and nerve hypertrophy using haematoxylin-eosin stain was 99.1% and 94.4%, respectively. Correlation of haematoxylin-eosin staining with calretinin and S100 was statistically near perfection (κ= 0.976 and κ = 0.923), respectively. CONCLUSIONS: The mainstay to confirm or exclude Hirschsprung disease remains an accurate histopathological evaluation of the haematoxylin-eosin-stained sections of an adequate colorectal biopsy.
