Wild Banana Seed Phytobezoar Rectal Impaction Causing Intestinal Obstruction.

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Toxicology

Background:

• Phytobezoars, particularly those derived from wild banana seeds (Musa acuminata subsp. microcarpa), are exceptionally rare causes of adult rectal impaction.
• Intestinal obstruction secondary to phytobezoars can lead to significant clinical complications.

Purpose of the Study:

• To report a unique case of wild banana seed phytobezoar causing rectal impaction, intestinal obstruction, and fecal overflow incontinence in an adult.
• To increase awareness of this rare clinical entity and its potential public health implications.

Main Methods:

• Case presentation of a 75-year-old male with dementia presenting with abdominal pain, rectal bleeding, and overflow incontinence.
• Diagnostic workup including clinical assessment, imaging, and identification of the causative agent.
• Discussion of the patient's management and clinical course.

Main Results:

• A large wild banana seed phytobezoar was identified as the cause of rectal impaction, leading to intestinal obstruction, stercoral ulceration, and fecal overflow incontinence.
• The specific wild banana species was identified as Musa acuminata subsp. microcarpa.
• Successful management of the condition was achieved.

Conclusions:

• Wild banana seed phytobezoar impaction is a rare but serious condition that can cause significant gastrointestinal distress and obstruction in adults.
• Public consumption of wild bananas should be discouraged to prevent such occurrences.
• Increased clinical awareness and prompt identification are crucial for effective management.
