“…Small bowel obstruction due to an appendiceal inflammation or adhesion is an uncommon presentation, with patients presenting with symptoms of gastrointestinal obstruction, with or without systemic sepsis [1]. Appendicitis causing small bowel obstruction was first described in the literature by Naumov et al in 1963, and in this case we discuss an even rarer occurrence of this presentation with the additional presence of a low grade mucinous neoplasm [2].…”

“…the literature; however, almost exclusively in the context of appendicitis [4][5][6]. An "appendiceal tie" strangulating the small bowel via appendicitis has been documented in the literature and was first described by in 1963 [2,5,7]. A classification system for SBO in the context of appendicitis has been suggested, with mechanisms via adynamic (paralytic ileus), mechanical without strangulation, strangulation, and finally mesenteric ischemia [8]…”

Introduction: Low grade appendiceal mucinous neoplasms are generally encountered incidentally in appendicectomies for suspected appendicitis. This case is a documentation of a rare occurrence of LAMN presenting with small bowel obstruction. Case Report: An 83-year-old male presented to the Emergency Department with a three day history of nausea, vomiting, and obstipation and profoundly dehydrated. Computed tomography revealed a high grade small bowel obstruction with 2 transition points in the right iliac fossa, concerning for closed loop obstruction, necessitating an urgent laparotomy. Conclusion: While acute appendicitis is a common cause of emergency abdominal pathology, when coupled with small bowel obstruction, a neoplastic cause should be considered as part of the differential diagnosis.

Introduction: Small bowel obstruction (SBO) is common surgical pathology, most commonly secondary to adhesions. This case presents a novel cause of small bowel obstruction. Case Report: We present a case of an elderly female who presented to hospital with symptoms, signs, and radiological findings consistent with SBO. After failing non-operative management, and deteriorating clinically, decision was made for operative intervention. A laparotomy revealed a normal-appearing appendix adhering to the pelvic side wall, and consequently forming a band adhesion-like internal hernia and was the cause of the bowel obstruction. Following dissection from the pelvic wall, and appendectomy, the patient recovered and was discharged home. Histopathology demonstrated a normal appendix. Diseased appendices have rarely been described to cause bowel obstructions; however, this is the first case report describing a normal appendix causing a band-like bowel obstruction. Surgical management was necessary to establish a definitive diagnosis, and for resolution of the condition. Conclusion: This case highlights a novel cause of SBO and reiterates the heterogeneity of SBO causes. Abdominal exploration remains the gold standard diagnostic modality for intra-abdominal pathology.
