   Rectal Foreign Body

   Patient presents with retained rectal object

   1. ●

      Action

      Initial Assessment

      History and examination

      • Non-judgmental approach essential
      • Object type, size, shape
      • Duration since insertion
      • Prior extraction attempts
      • Abdominal pain/tenderness
      • Signs of perforation/sepsis
      • Mental status (rule out body packing)
      1. ●

         Action

         Imaging Studies

         Assess object and complications

         • Abdominal X-ray (KUB): Location, number, type
         • CT if perforation suspected
         • Look for: Free air, object location
         • Above vs below rectosigmoid junction
         • Multiple objects possible
         • Document for medicolegal purposes
         1. ◆

            Decision

            Signs of Perforation?

            Determines urgency

            • Free air on imaging
            • Peritonitis on exam
            • Sepsis/shock
            1. ⚠

               Warning

               EMERGENCY LAPAROTOMY

               Perforation requires surgery

               • Exploratory laparotomy
               • Repair perforation or resection
               • Remove foreign body
               • Washout
               • Stoma if significant contamination
               1. ●

                  Action

                  Post-Extraction Assessment

                  Evaluate for injury

                  • Rigid/flexible proctosigmoidoscopy
                  • Assess for mucosal injury
                  • Full-thickness injury vs abrasion
                  • If injury: CT to confirm no perforation
                  • Document extent of trauma
                  • Photos if appropriate
                  1. ◆

                     Decision

                     Significant Injury Found?

                     Determine disposition

                     1. ●

                        Action

                        Observation/Discharge

                        No significant injury

                        • Clear liquids, advance diet
                        • Pain management
                        • Stool softeners
                        • Return precautions
                        • Psych/social work if appropriate
                        • Follow-up in 1-2 weeks

                           Outcomes

                           Statistics and follow-up

                           • Transanal success: 60-75%
                           • OR extraction success: 90%+
                           • Perforation rate: 1-5%
                           • Recurrence: Address underlying factors
                     2. ●

                        Action

                        Manage Injury

                        Based on severity

                        • Partial thickness: Observation, antibiotics
                        • Full thickness: Surgery likely
                        • Sphincter injury: May need repair
                        • Serial exams for delayed perforation
