Rare pelvic peritoneal defect causing small bowel obstruction in a young female with virgin abdomen.

This case report discusses a 46-year-old female with no prior surgical history who presented with severe abdominal pain and generalized tenderness. She was found to have a small bowel obstruction secondary to internal hernia caused by a rare congenital pelvic peritoneal defect in the Pouch of Douglas. She required diagnostic laparoscopy and repair of the pelvic peritoneal defect. Congenital peritoneal defect is an extremely rare cause of small bowel obstruction but should remain a possible differential diagnosis in patients with virgin abdomen presenting with acute abdominal pain.

A rare cause of colonic pseudo-obstruction due to light chain amyloidosis.

In this case report, we discuss the rare presentation of a 56-year-old-gentleman with a history of light chain amyloidosis (AL), causing colonic pseudo-obstruction and requiring open subtotal colectomy and end ileostomy. This should remain a differential diagnosis in patients with known light chain AL presenting with nonspecific gastrointestinal symptoms such as constipation and abdominal pain. This prompts early investigation, such as endoscopy and tissue biopsy, and surgical intervention may be warranted.
