Exsanguinating blunt polytrauma with liver and destructive colon injury — abbreviate, resuscitate, pack, time the return

Model answer

(A) Abbreviate by physiology, resuscitate by ratio and clock (4 marks). Damage control surgery is abbreviated laparotomy prioritising short-term physiological recovery over anatomical reconstruction — three steps (abbreviated operation, ICU restoration, planned definitive repair), extended to six phases with DCR as phase 0 — while DCR is hypotensive resuscitation with early blood products that may let borderline patients avoid DCS entirely.^[3][5][1] He meets the damage-control admission panel: hypotension, tachycardia, positive FAST, lactate above 6, temperature below 35 — against independent early-mortality predictors of INR above 1.2, base deficit above 3, head AIS 3 or more, temperature below 35, lactate above 6 and haemoglobin below 7, from a cohort where 16.3 percent died early with lactate 5.81 versus 3.46 separating early deaths from survivors.^[13] Run balanced products toward empiric 1:1:1 per EAST (protocol OR 0.61, high plasma OR 0.60, high platelets OR 0.44), accepting PROPPR's honesty — no mortality difference, fewer exsanguinations (9.2 versus 14.6 percent), more haemostasis (86 versus 78 percent).^[25][24] Give TXA now as 1 g over 10 minutes then 1 g over 8 hours: within-1-hour treatment cut bleeding death (RR 0.68), 1-to-3-hour helped (RR 0.79), beyond 3 hours seemed harmful (RR 1.44) — with benefit concentrated inside 90 minutes to 2 hours.^[26][27]

(B) Pack the liver, divert or delay the colon, close with traction (3 marks). Pack for coagulopathic liver bleeding — packing controlled 18 of 22 complex injuries definitively — and remove packs between 36 and 72 hours with first re-look after 48 hours: 24-hour removal rebled more than 48-hour, and under-36-hour removal rebled 21 versus 4 percent with equal complications.^[42][40][41] For the destructive sigmoid injury, never anastomose at stage 1: delayed anastomosis at re-look leaked in 25 percent with significantly higher mortality when leak occurred, while diversion matched on overall and colon-related mortality — staple and leave discontinuous, divert or delay in the selected.^[48] Close temporarily with vacuum plus fascial traction, not Bogotá bag: traction-plus-vacuum led vacuum alone by 35 points for definitive closure in the RCT-only meta-analysis, mesh-mediated traction closed 73 versus 54.9 percent and cut failed-closure odds ten-fold in Finland.^[53][51][49]

(C) Return within 24 hours, close at the earliest honest moment, quote the harms (3 marks). Readiness is lactate normalisation (10 percent dead inside 24-hour normalisation, 67 percent when never normalised), but the closure odds decay per takeback: 92.9 percent fascial closure at 61 hours, minus 91.5 percent odds per extra re-laparotomy, first takeback within 24 hours — so return early and make the definitive operation definitive.^[21][50] An open abdomen that could have been closed is a complication: matched peritonitis data showed more complications (71.2 versus 41.4 percent), higher mortality (22.5 versus 11.7 percent) and longer stay with open abdomen — with overnight and operator variation proving the decision is system-dependent.^[65] Counsel by age honestly: over-55 damage-control mortality 29.4 versus 4.8 percent (laparotomy 55.6 versus 7.1) yet most elderly survived with comparable morbidity — intervene, do not presume futility.^[68]
