The Randomized Controlled Trial of Coca-cola's Clinical Effects on Gastric Phytobezoars

Consecutive patients suffering from gastric phytobezoars were divided into 3 groups (Group 1, Group 2 and Group 3) according to the phytobezoars' formation time and each group was further subdivided into control and intervention group according to whether Coca-Cola was admitted. All patients in intervention group dieted Coca-Cola whereas patients in control group refused to drink Coca-Cola and had willing to receive the emergently gastric fragmentation.

Intraluminal causes of mechanical small bowel obstruction: CT findings and diagnostic approach

Review

Author: Wong, Laura ; Chung, Andrew D ; Haider, Maera ; Sivanesan, Umaseh

Intraluminal causes of small bowel obstruction (SBO) are less common than mural or extrinsic etiologies. This review categorizes intraluminal causes of SBO into four broad categories to provide a diagnostic framework for radiologic interpretation: 1) ingested contents, 2) bowel stasis, 3) inflammatory causes, and 4) neoplasms. Ingested materials can result in SBO when individual or accumulated contents are too large to pass, such as in the case of foreign bodies or bezoars. Bowel stasis causing SBO can be secondary to abnormal bowel function, such as in cystic fibrosis, reduced transit of contents at sites of narrowing such as surgical anastomoses, or the formation of enteroliths in diverticula which may subsequently dislodge and result in luminal obstruction. Inflammatory causes of SBO include strictures or fistulas that allow foreign bodies (such as gallstones) formed outside the bowel to enter the bowel lumen and cause obstruction. Finally, neoplasms can present as endophytic masses that occlude the bowel lumen through a ball-valve mechanism or serve as a lead point for intussusception. Recognizing the imaging features that are suggestive of intraluminal SBO is critical for accurate diagnosis and timely patient care.

INTRODUCTION AND IMPORTANCEIndividuals with Autism Spectrum Disorder (ASD) are at greater risk of experiencing co-occurring gastrointestinal (GI) symptoms, including chronic constipation and acute intestinal obstruction, due to bezoars secondary to pica. This case highlights the importance of clinic evaluation of autistic patients presenting with obstructive gastrointestinal symptoms and its further impact on management of the patients.CASE PRESENTATIONAn 11-year-old male patient who has had autism since childhood presented to the emergency department with chief complaint of difficulty in passing stool for one month which was associated with failure to pass flatus, severe abdominal pain and loss of appetite. The relative reported that the patient had a tendency of eating inorganic materials when unsupervised like hair, cushion sponges or sand. An abdominal mass was palpated at the left lower quadrant of the abdomen. Abdominopelvic CT-Scan showed fecal impaction. The patient was managed conservatively by manual evacuation under general anesthesia.CLINICAL DISCUSSIONColonic bezoars presenting with obstructive symptoms is a rare finding. It should be thought of in autistic patients with habit of pica. Diagnostic imaging modalities such as X-ray and CT scan are of paramount importance in confirming the diagnosis. Initial management involves conservative measures for uncomplicated cases.CONCLUSIONBezoars should be considered as cause of intestinal obstruction in patients with habit of pica, especially in those with autism spectrum disorders. Multidisciplinary approach to diagnosis, intervention, and long-term management in assuring patients' overall well-being should sought.
