Ultrasound-guided rectus sheath block for improvement of feelings of abdominal distension

ABSTRACT

We report a case in which feelings of abdominal distension and discomfort of the abdominal wall caused by malignant ascites were relieved by ultrasound-guided rectus sheath block. <b>Case report</b> A 59-year-old man developed gastric cancer with malignant ascites and experienced feelings of abdominal distension, but no nausea, dyspnea, poor mobility, or limb edema. Symptom control was inadequate with diuretic therapy and abdominal paracentesis. Feelings of distension improved temporarily with ultrasound-guided rectus sheath block. A percutaneous catheter was then used to administer an infusion of 0.25% ropivacaine triweekly until his death 20 days later. <b>Conclusion</b> Feelings of abdominal distension is one of various symptoms of severe ascites and is difficult to manage. Ultrasound-guided rectus sheath block can be used to relieve this symptom on a case-by-case basis.
