The inability to pass stool for a prolonged period can lead to the formation of fecaliths, which occurs most often in the colon or rectum. Although large fecaliths can lead to serious or life-threatening complications, the detailed process of their formation is unknown. This report describes a 65-year-old woman who presented with melena due to ischemic proctitis caused by a large fecalith. On computed tomography, the fecalith showed a unique multilayered calcification sign. We successfully dismantled and removed the fecalith transanally, assisted by a traction method using a balloon catheter. A review of imaging studies from 6 years ago revealed the growth of the fecalith over the previous year and provided an insight into the mechanism underlying the development of large fecaliths.

Meckel's diverticulum is a common congenital malformation of the small intestines. This true diverticulum can lead to complications such as intestinal obstruction, bleeding, and rarely perforation, particularly in adults where the diagnosis is uncommon and often complicated by overlapping symptoms with conditions such as acute appendicitis. Giant Meckel's diverticulum (>5 cm) cases are extremely rare and pose significant clinical challenges due to severe complications.

Article Synopsis
- - Acute appendicitis is a common surgical emergency characterized by right lower quadrant abdominal pain, more frequently observed in men than in women of childbearing age, and can be diagnosed using various imaging techniques like ultrasound and CT scans.
- - Management depends on whether the appendicitis is uncomplicated or complicated; uncomplicated cases may be treated with antibiotics, while complicated cases require surgical intervention, especially for patients with abscesses.
- - Special considerations are needed for certain groups (like pregnant or immunosuppressed patients) who should receive timely surgical treatment to minimize complications.

While uncommon, maintaining a high clinical suspicion in the appropriate setting is crucial. We present a case report involving a 52-year-old female with no history of chronic constipation, who presented with an unexplained large bowel obstruction.
