Colic - Sentsuu (English spelling)

Japanese: 疝痛 - せんつう（英語表記）colic

Severe abdominal pain that often occurs periodically at regular intervals. It is caused by spasms and contractions of the smooth muscles in the walls of the digestive tract, such as the stomach and intestines, or tubular organs, such as the biliary tract, renal pelvis, and ureters. Chronic appendicitis and various stones can also cause colic. As it is paroxysmal and periodic, and is affected by body position and movement, patients often place their hands on the painful area and assume a position that relaxes the affected area. Gastric colic is the most common, followed by biliary colic (gallstones). Treatment should aim to remove the cause, but analgesics and antispasmodics are also administered.

一定の時間をおいて周期的に現れることの多い，腹部の激痛。胃，腸など消化管，あるいは胆道，腎盂，尿管など管状器官の壁に存在する平滑筋のけいれんと収縮に基づくもので，慢性化した虫垂炎や，いろいろな結石なども疝痛の原因になる。発作的，周期的であるとともに，体位，体動が影響を与えるので，患者は常に疼痛部に手を当て，患部の緊張をゆるめる姿勢をとることが多い。胃疝痛が最も多く，胆道疝痛 (胆石症) がこれに次ぐ。治療には原因除去が望ましいが，鎮痛・鎮痙薬を投与する。
