The answer is: Diverticula. Diverticula are sacs or pouches caused by herniation of the mucosa through a weakened portion of the muscular coat of the intestine or other structure.

• Fissures: Incorrect. Fissures are tears or splits in the tissue, often occurring in the anal region.
• Strictures: Incorrect. Strictures refer to the narrowing of a passage in the body, such as the esophagus or intestines.
• Diverticula: Correct. These are pouches that form when the mucosal layer of the intestine herniates through the muscular layer.

The answer is: herniorrhaphy. When a herniorrhaphy is performed, the protruding intestine is repositioned in the abdominal cavity and the defect in the abdominal wall is repaired.

• Herniorrhaphy: Correct. This is a surgical procedure to repair a hernia by repositioning the protruding tissue and repairing the abdominal wall.
• Hernioplasty: Incorrect. While similar, hernioplasty often involves the use of a mesh to reinforce the abdominal wall.
• Herniation: Incorrect. Herniation refers to the condition of an organ or tissue protruding through a weak spot in the surrounding muscle or tissue.

The answer is: right-sided. Symptoms of a right-sided lesion include dull abdominal pain and melena.

• Right-sided: Correct. Right-sided lesions in the colon can cause symptoms such as dull abdominal pain and melena (black, tarry stools due to bleeding).
