IMPACTION OF PELVIC FLEXURE OF COLON-RECOVERY, 
By W. D. Critoheeson, D.Y.S. 
On Monday, June 2 d, I was called to see a bay gelding, 
between six and seven years of age. 
History .—Had been owned by the present owner a little more 
than one year; was in fair condition, ate greedily, grain as well 
as the straw used for bedding; performed his work well, but was 
not able to increase his avoirdupois. On the day before (Sunday), 
for the first time, he had an attack of colic; owner treated with 
homoeopathic doses of aconite and belladonna. Several hours 
after the attack he purged quite violently, the foeces having a very 
offensive odor. After this he seemed to be relieved, but still 
showed some abdominal irritation. 
Monday morning .—He was still purging, and had intermittent 
pain. When I was called, found condition nearly normal. Diag¬ 
nosed case as one of intestinal irritation, probably caused by over 
feeding on grass. Gave chloral hyd., 3 vi. in pill form, and 
ordered gruel, with small quantity of hay. Saw him again late in 
the afternoon ; found slight rise in febrile condition ; pain at times 
quite severe. Ordered a mixture of opium, belladonna and 
ginger, combined with an alcoholic stimulant in form of gin. 
Tuesday June 3d.—Fain more violent, with expulsive efforts, 
and with little intermission. Had passed neither foeces or urine 
since early Monday morning. Suspecting impaction, made rectal 
examination, and found bladder partially tilled with fluid, and 
lying well back in pelvic cavity, having been displaced by pelvic 
flexure of colon, which was firmly wedged in the inlet of pelvis. 
The mass was hard, and could not be displaced forward on account 
of violent expulsive efforts. Condition at this time: Temper 
ature, 101°; pulse, 48 ; respiration, 120 . Gave aloes Barb, 3 i, 
01. Lini, § x, and passed catheter. To allay pain, gave hypoder¬ 
mically gr. iv. of morphia. Throughout the day continued to give 
the anodyne mixture of opium and belladonna. 
Wednesday .—Condition about the same. Hypodermic injec¬ 
tions gave more relief than anything else. Continued the same 
treatment with the addition of rectal injections.
