Statement of Purpose: This paper uses 139 published case reports to understand the demographic, diagnostic, and treatment trends of intussusception of the appendix. Methods: Using the PubMed literature search engine to find all English references of “intussusception” and “appendix”, and reviewing those that contained actual case reports of intussusception of the appendix, we analyzed the demographics, presentation, diagnostic methods, surgical treatment, and histology from 140 articles representing data from 181 patients.

  • Twisted Bowels: Intestinal Obstruction Blake Briggs, MD Mechanical
    Twisted Bowels: Intestinal obstruction Blake Briggs, MD Objectives: define bowel obstructions and their types, pathophysiology, causes, presenting signs/symptoms, diagnosis, and treatment options, as well as the complications associated with them. Bowel Obstruction: the prevention of the normal digestive process as well as intestinal motility. 2 overarching categories: Mechanical obstruction: More common. physical blockage of the GI tract. Can be complete or incomplete. Complete obstruction typically is more severe and more likely requires surgical intervention. Functional obstruction: diffuse loss of intestinal motility and digestion throughout the intestine (e.g. failure of peristalsis). 2 possible locations: Small bowel: more common Large bowel All bowel obstructions have the potential risk of progressing to complete obstruction Mechanical obstruction Pathophysiology Mechanical blockage of flow à dilation of bowel proximal to obstruction à distal bowel is flattened/compressed à Bacteria and swallowed air add to the proximal dilation à loss of intestinal absorptive capacity and progressive loss of fluid across intestinal wall à dehydration and increasing electrolyte abnormalities à emesis with excessive loss of Na, K, H, and Cl à further dilation leads to compression of blood supply à intestinal segment ischemia and resultant necrosis. Signs/Symptoms: The goal of the physical exam in this case is to rule out signs of peritonitis (e.g. ruptured bowel). Colicky abdominal pain Bloating and distention: distention is worse in distal bowel obstruction. Hyperresonance on percussion. Nausea and vomiting: N/V is worse in proximal obstruction. Excessive emesis leads to hyponatremic, hypochloremic metabolic alkalosis with hypokalemia. Dehydration from emesis and fluid shifts results in dry mucus membranes and oliguria Obstipation: severe constipation or complete lack of bowel movements.

  • Delayed Presentation of a Retained Fecalith
    Open Access Case Report DOI: 10.7759/cureus.15919 Delayed Presentation of a Retained Fecalith Fawwad A. Ansari 1 , Muhammad Ibraiz Bilal 1 , Muhammad Umer Riaz Gondal 1 , Mehwish Latif 2 , Nadeem Iqbal 2 1. Medicine, Shifa International Hospital, Islamabad, PAK 2. Gastroenterology, Shifa International Hospital, Islamabad, PAK Corresponding author: Fawwad A. Ansari, [email protected] Abstract A fecalith is a common cause of acute appendicitis, and laparoscopic surgery is the mainstay of its management. Literature review shows that a fecalith may be retained in the gut following a laparoscopic appendectomy in some rare cases. In most cases, the fecalith becomes symptomatic with time due to the formation of an abscess, fistulous tract, or inflammation of the appendicular stump (stump appendicitis). We report a case of retained appendicular fecalith presenting with symptoms similar to acute appendicitis, 15 years after laparoscopic appendectomy. Categories: Gastroenterology, General Surgery Keywords: colonoscopy, acute appendicitis, appendectomy, fecalith, right iliac fossa pain, complications Introduction A fecalith is a hard stony mass of feces in the intestinal tract. Fecal impaction occurs when a large amount of fecal matter gets compacted and cannot get evacuated spontaneously [1]. In its extreme form, fecal impaction can lead to the formation of a fecalith due to the hardening of fecal material that forms a mass separate from other bowel contents [2]. It can occur in any part of the intestine [1]. Most often, a fecalith arises in the colon (mostly sigmoid) or rectum and very rarely in the small intestine [2]. Here we present a case of a retained appendicular fecalith in a patient who presented with an acute abdomen.

But the diagnosis in such patients can be challenging for a clinician because of the diverse etiologies. Acute abdominal pain is commonly caused by self-limiting con- ditions but also may herald serious medical or surgical emergencies, such as appendicitis. Making a timely diag- nosis is important to reduce the rate of complications but it can be challenging, particularly in infants and young children. Excellent history-taking skills accompanied by a careful, thorough physical exam are key to making the diagnosis or at least making a reasonable conclusion about a patient’s care.2 This article discusses the differential diagnosis for acute abdominal pain in children and offers guidance for initial evaluation and management of pediatric patients presenting with this complaint. © Getty Images Contrary to visceral pain, somatoparietal pain is well Pathophysiology localized, intense (sharp), and associated with one side Abdominal pain localization is confounded by the or the other because the nerves associated are numerous, nature of the pain receptors involved and may be clas- myelinated and transmit to a specific dorsal root ganglia. sified as visceral, somatoparietal, or referred pain.

Background • Colonic diverticula are sac-like protrusions of the colon wall – mucosa pushing through muscular layer defects (as opposed to outpouching of all layers) – Associated with increased intraluminal pressures • Diverticulosis describes the presence of multiple diverticula – Predominantly left-sided in the Western hemisphere – Prevalence rates of 5 to 45%; most commonly seen in elderly • Diverticulitis is inflammation in the setting of diverticulosis, usually due to fecalith obstruction and infection leading to micro- or macro-perforation of a diverticulum – Occurs in ~4% of patients with diverticulosis – Acute complications occur in ~25% of patients • Complications can include bowel obstruction, abscess formation, peritonitis and fistula formation Diagnosis • Patients typically present with lower abdominal pain and tenderness – Left-sided in ~85% of cases; often gradually becomes more generalized • Symptoms resemble “left-sided appendicitis” – Other symptoms can include fever, nausea, vomiting, constipation and diarrhea – Peritoneal signs and palpable mass (“inflammatory phlegmon”) may be present – May have a mild leukocytosis (~55%) • CT is the imaging modality of choice
