Objective To examine the therapeutic effect of standardized whole-process catharsis and removing food stagnation method in treating severe acute pancreatitis（SAP） excess of Yangming fu-viscera syndrome.Methods Fifty-two SAP patients with excess of Yangming fu-viscera syndrome were divided into a treatment group（27 cases） and a control group（25 cases） according to different therapeutic methods. In addition to routine western medicine treatment

the treatment group was added unified method of catharsis and removing food stagnation plan and whole-process treatment until the buffer period. In addition to basic western medicine treatment

the control group was added method of catharsis and removing food stagnation treatment only in the early stage of the disease（until fecal excretion）

and the treatment was not standardized and unified. Laboratory indexes

scale scores

Chinese medicine clinical syndrome scores

abdominal pain scores

incidence of gastrointestinal dysfunction and adverse events in both groups were compared. Results The improvement of hemodlastase

leucocyte count

C-reactive protein

blood calcium

acute physiology and chronic health score

bedside index of acute pancreatitis severity

Chinese medicine clinical syndrome scores and CT severity index in the treatment group was faster than those in the control group（P <0. 05）. Abdominal pain seemed to be relieved faster in the treatment group than in the control group. Gastrointestinal dysfunction seemed to be improved better in the treatment group than in the control group. The incidence of adverse events

such as secondary infection and death

seemed to be reduced in the treatment group（P < 0. 05）.Conclusion Standardized method of catharsis and removing food stagnation whole-process treatment in SAP patients might quickly relieve abdominal pain

improve gastrointestinal dysfunction

reduce the incidence of adverse events

such as secondary infection and death

as well as improve patients’ prognosis.
