treatment of chylothorax乳び胸の治療は胸腔ドレナージと栄養管理が基本である．胸腔ドレナージにより貯留した乳びを排出し，肺の圧迫を解除する．栄養管理では☆絶食＋中心静脈栄養とし，乳びの産生を抑制する．このとき，胸管を介さずに門脈系に取りこまれる中鎖脂肪酸（MCT）の割合を増やすことで，乳びを減らす方法も試みられる．また，近年,オクトレオチド（ソマトスタチンアナログ）が有効であるとの報告もある．
treatment of pneumothorax■ stable, small (<2 cm between lung and chest wall on x-ray), minimal symptoms: observation + O2
■ symptomatic or large (>2 cm): aspiration
■ unstable/tension pneumothorax: needle decompression then chest tube, and VATS if unsuccessful

treatment for large bowel obstruction (LBO)•supportive management: IV fluids, gastrointestinal decompression; 75% require surgical intervention
•surgical correction of obstruction
•volvulus: ☆initial decompression with flexible sigmoidoscopy, operative reduction or sigmoid resection dependent on severity
•mechanical obstruction: ostomy alone(fecal diversion), colectomy with primary anastomosis or Hartmann procedure. May pursue stenting as bridging (follow with another intervention) or palliation gastrointestinalsurgery国試過去3回 Sep 23, 2020, 12:05 AM HirotoShishido

Leriche syndromeThigh claudication is suggestive of occlusive disease of the ipsilateral external iliac artery or its more distal branches (ie, common femoral, superficial femoral, profunda femoris arteries).
Accompanying ☆★impotence and/or ☆gluteal claudication suggests ☆more proximal aortoiliac occlusion (so-called Leriche syndrome), which, in addition to affecting the external iliac artery, also diminishes blood flow to the internal pudendal and gluteal branches of the internal iliac artery. cardiologysurgeryUWorld step2CK Jun 27, 2020, 5:57 AM HirotoShishido
thracentesis
locationThoracentesis is typically performed between
①the 6th and 8th ribs along the midclavicular line,
②☆the 8th and 10th ribs along the midaxillary line (above image),
③and the 10th and 12th ribs along the paravertebral line.
This allows pleural fluid to be drained without risking lung injury (which can occur at higher insertion sites). However, insertion of a needle ☆below the 9th rib still risks penetrating abdominal structures. surgeryUWorld Mar 22, 2020, 7:28 AM HirotoShishido
