`
`SUMMARY Theprevalence of symptomsand stool patterns was assessed prospectively in 96 patients
`with ulcerative colitis subdivided according to the extent and activity of the disease. Increased
`frequency of defecation (83%), urgency (85%), a feeling of incomplete evacuation (78%) and
`tenesmus (63%) were the most frequent symptoms experienced by patients with activecolitis. All
`weresignificantly more common (p<0-001) in patients with active than quiescent colitis and their
`prevalence was similar in those with total and distal colitis, indicating that these symptoms are
`related to an inflamed andirritable distal colon. Twenty seven per cent of patients with activecolitis
`voided hardstools indicative of constipation, however, and this was more commonin active, than
`quiescentcolitis (p<0-05). This feature is probably secondaryto faecalstasis in the proximal colon,
`and an apt description of the bowel disturbance in ulcerative colitis, irrespective of the extent of
`disease is that the colon suffers from proximal constipation anddistalirritability.

`
`Methods
`
`For a condition in which change of bowel habit is a
`major manifestation, there is a surprising dearth of
`objective data on bowel symptoms in ulcerative
`colitis, and this is reflected by the very inadequate
`and poorly referenced accounts in many standard

`textbooks of medicine and_gastroenterology.

`
`which they indicated the presence or absenceofsix
`symptoms
`related to defecation. These were:
`(1) urgency (an irresistible and urgent desire to
`defecate), (2) feeling of incomplete evacuation (a
`strong andpersistent desire to evacuate after defeca-
`tion), (3) tenesmus(continualinclination to evacuate
`bowels accompanied bypainful straining), (4) pain
`(lower abdominal orrectal pain, with or without any
`relation to defecation), (5) perianal soreness (intense
`discomfort or itching of the perianal skin), (6) faecal
`incontinence (inability to control defecation volun-
`tarily resulting in leakage of motions and/orsoiling of
`garments). A clear explanation of each symptom was
`providedat the timeofthe interview.
`In addition, all patients were asked if their stools
`were predominantly loose, formed or hard, if they
`were associated with blood and mucus, and if they
`had to wake upat night to defecate. Their average
`daily bowel frequencywasalso recorded.
`
`STATISTICAL ANALYSIS
`
`The differences in the stool consistency and in
`the prevalence of symptoms between active and
`quiescent disease were analysed using x’ tests. Data
`on stool frequency were compared by Wilcoxon’s
`rank-sum tests.
`
`Results
`
`PREVALENCE OF SYMPTOMS
`
`Theprevalence of the six bowel symptomsin patients
`
`with ulcerative colitis is shown in the Table. Patients
`with active disease exhibited a higher prevalence
`of urgency, a feeling of incomplete evacuation,
`tenesmus, pain, anal soreness and faecal incontin-
`ence, comparedwith patients with quiescentcolitis.
`The prevalence of these symptoms did not vary
`significantly with the extent of the disease (Table).
`Fourteen patients (women=12, men=two) with
`active colitis reported faecal incontinence. All except
`two (one woman, one man) were over 60 years of
`age.
`
`STOOL PATTERNS
`As would be expected, the frequency of defecation
`was higher in patients with active than quiescent
`colitis,
`irrespective of the extent of the disease
`(Table). Eighty three per centof patients with active
`colitis were defecating more than three times a day.
`No patient with quiescent colitis experienced this
`degree of stool frequency. Nocturnal defecation was
`reported by 81%of patients with active total colitis
`and 56% of patients with active distal colitis, but by
`none of the patients with quiescent colitis. There
`was nosignificant difference in the prevalence of
`nocturnal defecation betweenpatients with total and
`distal colitis.
`Ninety six per cent of patients with active colitis
`passed blood and mucusin their stools every day. In
`contrast only 8% of patients with quiescent disease
`occasionally passed blood and 12% occasionally
`passed mucusintheir stools.

`
`Although the proportion of stools which were
`unformed wassignificantly higher in patients with
`active than quiescentcolitis (Table), many patients
`with active disease passed formed orhardstools.
`A higher proportion of patients with active colitis
`(27%) than quiescent colitis (8% ) reported that their
`stools were hard (p<0-05), and this was true in both
`distal colitis and total colitis, although in the case of
`total colitis this did not reachstatistical significance
`(Table). Twooffour patients with active proctitis and
`one of three with quiescent proctitis voided hard
`stools. The hard stools of active colitis were always
`accompanied by blood and mucusand were associ-
`ated with symptoms of tenesmus and a feeling of
`incomplete evacuation.
`
`Discussion
`
`Although most patients with active colitis had
`increased stool frequency and were voiding blood
`and mucus in their stools,
`the results of stool
`consistency were surprising. Twenty eight of 60
`(47%) patients with active colitis reported they were
`passing formed stools and in as manyas 16 (27%)
`patients, the stools were hard. This showsthat liquid
`diarrhoeais by no meansa constant feature of active
`colitis. Instead, the passage of hard stools suggests
`that by this criterion at least a sizeable proportion of
`colitics are constipated. The observation that the
`passage of hard stools was more commonin patients
`with active than quiescent colitis suggests that in
`some patients hard stools are an index of disease
`activity. The existence of constipation in ulcerative
`colitis is supported by previous observations'**" but
`the frequency with which this occursandits relation-
`ship to the extent and activity of inflammation has
`never beenassessed prospectively. A large survey of
`450 patients published recently, has reported that
`only 3-5%of patients with colitis have constipationat
`the time of presentation." In this survey, the patients
`were asked to record their bowel habit as ‘normal’,
`‘diarrhoea’, or ‘constipation’. This form of assess-
`mentis unlikely to provide a clear picture, as most
`patients with colitis are often distracted by the
`frequent passage of blood and mucus.* If frequency
`of defecation is the sole criterion used,
`then the
`occurrence of constipation will be overlooked.
`The prevalence of important symptomsrelated to
`defecation has hitherto not been documented in
`patients with colitis. An urgent desire to defecate and
`a feeling of incomplete evacuation were reported by
`80-90%ofpatients with active colitis and by 10-15%
`of patients with quiescent colitis. Tenesmus was
`reported by 63%of patients indicating that painful
`straining during evacuation is an important and
`frequent manifestation of active colitis. The preval-
`
`ence of these and other symptoms assessed were
`similar in patients with total and distal colitis,
`suggesting that they are related to an inflameddistal
`colon. Tests of anorectal function have shownthat
`the rectum in patients with active colitis is hyper-
`sensitive’ (unpublished data), poorly compliant"
`and reacts excessively to intraluminal distension
`(unpublished data); features that could explain the
`symptoms of urgency and increased frequency of
`defecation.
`The occurrenceof nocturnal defecation and faecal
`incontinence invariably suggests active disease, as
`they were absent in patients with quiescent colitis.
`Eleven of 14 patients with incontinence were
`elderly women, andthis group of the population has
`been shown to be particularly susceptible to
`incontinence.” *
`Symptoms of increased bowel frequency, pain
`relieved by defecation, a feeling of incomplete
`evacuation and passage of mucushave beenreported
`to favour a positive diagnosis of irritable bowel
`syndrome.” As these symptoms are commonly
`presentin colitics, we agree with others” thatit is not
`possible to distinguish patients with functional bowel
`disturbance from those with organic boweldisease on
`the basis of these symptomsalone.
`Wehaverecently shown that patients with active
`colitis void small volumestools frequently, and have
`stasis in the proximalcolon and rapid transit through
`the rectosigmoid region, irrespective of the extent of
`colitis.” Our present study shows howthese changes
`in colonic function mayberelated to the symptomsof
`active disease, the proximal colonic stasis causing
`hard stools, and the irritable distal colon causing
`the more widely recognised frequent defecation,
`urgency,
`tenesmus, and a feeling of incomplete
`evacuation.
