直腸損傷を伴う重度不安定型骨盤損傷(活動性出血).Pelvic fracture with rectal injury








血管造影後の単純CTだから,図3〜図13の造影剤(△)は血管造影時に漏出したもので,図9〜図13の▲は図13でFoleyカテーテルのバルーンと連続するので膀胱内の尿であろう.直腸からS状結腸の走行は図14の1から図8の16の順に展開する.大事なことは,図11〜図16の↑は腸管外の遊離ガスであり,開放性損傷ではないので直腸損傷を疑うべきである.








下段は5日後に腹部膨満,腹部の皮下気腫と高熱が出現し,血圧が低下してきた時の単純CT.








図17〜図20で上行結腸(A),盲腸(C)と回腸末端を同定できれば,図18〜図27の,ガスと液状内容物でニボーを形成している※は図17と図28で盲端になるから膿瘍である.図26〜図29の白矢印も膿瘍であろう.図17〜図20の▲は皮下気腫で皮下膿瘍を,図26〜図32の△は筋層内,図29〜図32の↑は臀部筋層内のガスであり,いずれも膿瘍を示唆する.造影CTで診断が容易になる.手術で後腹膜に悪臭のする感染した血腫を認め,ドレナージを行ったが,敗血症性ショックが出現し翌日死亡した.第6病日という短期間に広範な膿瘍を形成したことは直腸穿孔を強く示唆する.

Preventable deaths from hemorrhage at a level I Canadian trauma center.
Tien HC, Spencer F, Tremblay LN, Rizoli SB, Brenneman FD.

BACKGROUND: Studies of trauma deaths have had a tremendous impact on the quality of contemporary trauma care. We studied causes of trauma death at a Level I Canadian trauma center, and tabulated preventable deaths from hemorrhage using explicit criteria. METHODS: Trauma registry data were used to identify all trauma deaths at our institution from January 1, 1999 to December 31, 2003. Demographics, mechanism, and time or location of death were recorded. Registry data analysis and selective chart or autopsy review were then performed to assign causes of death. RESULTS: A total of 558 consecutive trauma deaths were reviewed. Mean age was 48.7 (46.7-50.6), and mean Injury Severity Score was 38.8 (37.6-40.0); 29% were females. Blunt trauma represented 87% of all cases; penetrating injuries were only 13%. Central nervous system (CNS) injuries were the most frequent cause of death (60%), followed by hemorrhage (15%), and then combination CNS and hemorrhagic injuries (11%). Multiple organ failure caused 5% of deaths and 9% of deaths were from other causes. Of hemorrhagic deaths, 48% (n = 41) were from blunt injury, and 52% (n = 45) were from a penetrating mechanism. Of these hemorrhagic deaths, 16% were judged to be preventable because of significant delays in identifying the major source of hemorrhage. Hemorrhage from blunt pelvic injury was the major cause of exsanguination in 12 of 14 of these preventable deaths. CONCLUSIONS: Blunt injury is the major mechanism leading to trauma deaths. Massive bleeding from blunt pelvic injury is the major cause of preventable hemorrhagic deaths in our study.PMID: 17215745
