Colon & Rectum Injuries Prayuth Sirivongs M.D.
COLONIC INJURIES Anatomy • Cecum • Ascending colon • Transverse colon • Descending colon • Sigmoid colon
Etiology Penetrating Injury : Gun Shot ~ 75% Stab wound ~ 20% Blunt Injury :Motor vihicle Trananal Injury : Iatrogenic ; colonoscopy ,B.E. Sexual related : foreign body COLONIC INJURIES
Diagnosis Pre-operation Blood in rectum Acute abdomen series Water soluble contrast enema Triple contrast CT COLONIC INJURIES
COLONIC INJURIES Intra operation Rule of “ two “ Complete mobilize Blood staining Fecal odorsegmental squeeze
Treatment Colostomy Exteriorized repair primary repair COLONIC INJURIES
colostomy End Colostomy Protective Colostomy COLONIC INJURIES
colostomy End Colostomy Protective Colostomy COLONIC INJURIES
Indication for colostomy ( Stone & Fabian) 1.Shock c BP<80/60 mmHg 2.Intraperitoneal blood loss > 1000 ml 3.Intra-abdominal organ injuries > 2 organs 4.Significant fecal contamination 5.Time to operation >8 hrs 6.Colonic wound require resection 7.Major loss abdominal wall /Mesh COLONIC INJURIES
Colonic Injury Severity score(Shanon&Moore) Grade 1 ; Serosal injury Grade 2 ; Single wall injury Grade 3 ; < 25% wall involvement Grade 4 ; > 25% wall involvement Grade 5 ; Whole colonic wall involvement and blood supply injury COLONIC INJURIES
Exteriorized repair Avoided resection Reduced contamination Reduced colostomy Limited in some part of colon Stomal care is more difficult than colostomy COLONIC INJURIES
Primary repair Sutured repair Resection with primary anatomosis COLONIC INJURIES
Primary repair Sutured repair Resection with primary anatomosis COLONIC INJURIES
Primary repair Avoid colostomy Less morbidity than colostomy Gained more popularity Having high risk in patient c underlying medical illness massive blood transfusion COLONIC INJURIES
outcome cause of death exanguination sepsis ; intra- abdominalabscess multi organ failure fistula (primary repair) COLONIC INJURIES
Anatomy Promontary of sacrum to anus intraperitoneal extraperitoneal Length ~12-20 cm. RECTAL INJURIES

Etiology Penetrating injuries ; gun shot ~80% Stab & impalement <5% Blunt injury ~ 10% Transanal injury ; ~ 6% Anal intercourse Anal rape Iatrogenic ; enema, thermometer RECTAL INJURIES
Diagnosis Suspected in GSW ; Trunk , buttock , perineum upper thigh Stab ; buttock , perineum , lower abdomen Blood in rectum ( rectal exam ) RECTAL INJURIES
Investigation X-ray pelvis & abdomen; bullet tract,foreign body, fracture pelvis Rigid proctosigmoidoscope Water soluble contrast study RECTAL INJURIES
Treatment 1.Intraperitoneal rectal injuries;as colonic injuriession 2.Extraperitoneal rectal injuries ; Diversion Debridement Distal washout Presacral drainage RECTAL INJURIES
Diversion 1. Loop colostomy 2 .Loop colostomy c stapling distal lumen 3 .End colostomy c mucous fistula 4 .Hartmann’s procedure RECTAL INJURIES

Diversion 1. Loop colostomy 2 .Loop colostomy c stapling distal lumen 3 .End colostomy c mucous fistula 4 .Hartmann’s procedure RECTAL INJURIES
Diversion 1. Loop colostomy 2 .Loop colostomy c stapling distal lumen 3 .End colostomy c mucous fistula 4 .Hartmann’s procedure RECTAL INJURIES
2. Debridement : removed devitalize tissue repair defect if possible severe injury ; resection 3.Distal washout : decrease septic complication RECTAL INJURIES
4.Presacral drainage RECTAL INJURIES
Outcome Cause of death: Sepsis, Multi-organ failure Anorectal abscess Rectal fistula RECTAL INJURIES
