K WOOLFSON, GR GREENBERG. Symptomatic improvement of gastroduodenal Crohn's disease with omeprazole. Can J Gastroenterol 1992;6( l ):2 1-24. Four patients with ilea! C rohn's disease presenteJ with abdominal pain aggravaceJ by food, ::i mean weight lo s of 5.5 kg (range 4 co 7) and ulceration of the antrum and/or d~1nJenum at gastroscnpy, without radiological features of mechanical obstruction . The endoscopic and histological appearance of the ulcers was consistent with C rohn's disease. O meprazole 40 mg da ily was admmistereJ, witho ut ocher drugs, and after three Jays of therapy pat ients were asymptomatic. After e ight weeks of omcprazole, a mean weight gain of 6 kg ( range 3 to 10) l 1ad occurred and the Jrug was withdrawn. O ne pat ient remained well and three patients relapsed, but all responJe<l to lo ng term o meprazole for up to three years. Fo llow-up endoscopies have inc.licated healing in one patient, pa rtial healing in two patients anJ no change in one patient. O mcprazolc may be of value in the symptomatic management of patients with gastroduodenal Crohn's disease.

RESUME: Q uatrc patients acteinrs de maladie Jc Crohn ileale ont rapportc des duulcurs abdominales aggravcc par lcs repas et unc penc pondcrale moyennc de 5,5 kg (4 a 7). L'cxamen g~stroscop ique a rcvcle des ulcerations de l'ancre et du JuoJcnum, sans signe J 'obstruccion mecanique. Les caracterist iques endoscopiquc et histologiques sembla icnt concorder et indiquer une maladie de Crohn. Aprcs crois jours de monothcrapic pa r l'omcprazolc (40 mg/jour) , lcs patients etaicnc asymptomatiques. Aprcs huit semaines, on a constacc un gain ponJcral de 6 kilos (de 3 a 10) cc mis fin au tra itcment. Les rcsultats sc soot maintcnus Jans un cas; trois pa tients one rccidivc mais tous o nt rcagi favorablement a un traitcmem sous omeprazole prolongc jusqu'a tro is ans. Le suivi endoscopique a pcrmis de note r la gucrison chez un patient, un rfaablisscment partiel chez deux patients et aucun changemcm chez le q uatricme. L'omcprazole pourrait s'avcrer uti le dans le cra itemcnt symptomatique des patients porceurs d'une maladic de Crohn gascroduodenalc.

T hese pal ients have po~tprand1al ahdom111.1I pain that often is ~imilar to peptic ulcer dbease, ye t t he maJorit y lose weight, even 111 the ahscnce llf mechanical ohstruction (I). Sympwmatic 1mprov1.'men1 after adm iniscrnt inn of I lz-receptor antagon ists has been reported for p.11 ients with gas1roduudcnal C:rohn\ disease (4), hue fre4ucn1 ly respome, arc 111complete and transient. Recent srud1es mdicate that rnneprazole, a potent mhibitnr of gastric acid secretion, may ht' more efficacious for l he management of patients with duodenal ulcer disease (5) and peptic esophagi tis (6). The present report describes four patients with nonohstruc tive acu ve gast roduudenal Cmhn's disease in whom a trial of omcprazolc therapy ahol ished pain and faci litated weight gain.

Consistl'nt with ,1ther repo rts (I , 3,7,8), Crohn's clisc,1se involving the sto mach and/or dunck num was nor always easily differen tiated from convcntillna l peptic ulcer.i t ion.

Moretwer, in acc,1 rd with prel' ious findings, h isto logy was frl'qucntly no t conclusive O) as hinpsy spec imens showed grnnulomas in only one of rhc present patients. The end(1scopic appearance of a1,hrhuid lesi(111s and thei r presence hcy(>nd the dundcm1I c,tp, coupled with ident ilka t icin of Crohn 's disease elsewhere in the gut, have heen
suggested as the lllllst import.mt signs fur the di ,1gnns is ,if gastroduodenal C rohn\ di ,case. In uther series (4,7) , Cn)hn's d isease occurred in rhe d1sral smal I howd and/or coh in in 8 3 w 9 3')(, p ( pat ienls 11rcsenting with involvement o( the .~astmdt1t >dcnum.

Numc1\ 1us approaches have hcen advoca ted for rhe treatment of pat ients with gastroduodenal Crohn's disease. An ti -ulcer regimen with l-1 2- receptor ant ;1gon ists and antacids were reported to provide sympto mmic re lief in five of l O 11,1tients for two to n ine months, hut then curt icos teroids were requi red ( 4). O ther moch1lities includ ing cort icostcroid,, singularly or in combinat ion with tn ta l paren tera l n utrit ion hal'e heen successful in the t remment of indiv idual pa tients wtlh gastmduodena l C rohn 's d isl'asc (9- 1 J ). 1-lmvel'er, in a rel'iew ot SC\'era l series hy Priebe and S imon (7) 23 of 30 patien ts ultimately came 1,1 surgery. T hus, any t hcrnpy th,11 dimin1.', hes sympt oms, f,1c il1tntcs weigh r gain and precludes the need (,1r cort ico,terrnds or surgery would be ,1d -1·antageous.
