Wound Infection Preventive Effects of the Lap-Protector in Open Acute Appendicitis Surgery: a Retrospective Study
Bibliographic record
Abstract
はじめに : 急性虫垂炎手術における術後創感染は,入院期間の延長により患者のQOLを損ね,医療費に与える影響も大きい.当院では,術後創感染防止策として,2008年4月から開腹下急性虫垂炎手術症例全例に対し,ラッププロテクター(Lap-protector;以下,LPと略記)を使用している.本稿では,当院の症例を振り返り,開腹下急性虫垂炎手術におけるLPの創感染防止効果につき検討した.対象と方法 : 2006年10月から2009年10月までの開腹下急性虫垂炎手術症例99例を対象とした.これらを2008年3月までのLP導入前の49例,2008年4月以降のLP導入後の50例に分け,両群間で臨床項目につき比較検討した.結果 : 両群間に患者背景,術前白血球数,術前CTでの腹水の有無,虫垂の炎症の程度に有意差はなかった.LP使用群では,非使用群と比較して術前CRP値は有意に高く,術前CTで膿瘍合併例が多い傾向があるなど,より炎症の進行した症例が多かったが,創感染合併例は認めなかった.一方,LP非使用群では7例に術後創感染を認めた.創感染合併例は創感染非合併例に比べ,入院日数は平均で4.6倍,入院費の出来高比較は2.9倍で,双方とも差は有意であった.考察 : LPの使用は,開腹下急性虫垂炎手術後創感染を明らかに減少させた.医療経済,患者の術後QOLの点から,開腹下急性虫垂炎手術におけるLPの有用性が示された.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
