Brooke’s (1954) description cannot be excelled : "... non-specific procto.-sigmoiditis, an insidious and indolent condition of the distal end of the large bowel, has been observed by many but recorded by few.... A mild, chronic and intractable inflammation is to be seen in the lowermost part of the rectum, often limited to the last two or three inches with a sharply defined upper limit ; less frequently its distribution throughout the rectal ampulla is patchy. On proctoscopy the rectal mucosa in the area involved is granular and bleeds to the touch. Over the course of years the inflammation may spread upwards to involve the sigmoid and at this stage the sigmoidoscopic appearance is not dissimilar from that found in ulcerative colitis ... the onset is insidious and slow and there is no constitutional upset when secondary anaemia results from constant blood except loss.""

compared with the results obtained with the manometric method of Van Slyke and Neil (1924) the relationship is found to be linear (fig. 4) ; but there is a systematic error which in the above example is z- 14% at 0% saturation. This error depends on the quantity of sodium hydrosulphite added to the samples in order to obtain the readings recorded in fig. 2.

The condition is, however, distressing to the patient and a social handicap, since the presence of blood in the rectum is apt to precipitate diarrhoea. Sigmoidoscopic recognition is easy : there is complete loss of the normal satiny sheen of the mucosa (Cropper 1945), whose place is taken by a coarse roughening of the surface due to the exposure of the deeper layers of the membrane. The inflammation fluctuates unpredictably, and no treatment can be regarded as specific. Since idiopathic granular proctitis has been so seldom described, I review here my own series of 26 cases (see table). This series excludes all cases of secondary granular proctitis, which fall into two groups : those in which the granularity is a forerunner or concomitant of true ulcerative colitis ; and those due to recurrent amoebic dysentery. In both these groups the appearances are identical with those of idiopathic granular proctitis, but in ulcerative colitis actual ulceration of the mucosa can often be seen, with or without blood and pus flowing Such evidence of actual down from higher levels. ulceration rules out, by definition, the diagnosis of
idiopathic proctitis. Similarly, granulation occurring as a stage in recurrent amcebic dysentery must almost invariably be regarded as a sequel of acute amcebiasis. Evidence of its amoebic origin will be forthcoming from the history or from serial sigmoidoscopies at which scrapings from ulcers contain entamoebae. In many cases the metamorphosis, over months, of ulcers into pin-point craters (Cropper 1945) and perhaps of craters into granularity, eliminates benign proctitis from the diagnosis. accompanying table shows the analyses ; fig. 4 was constructed from the The

A
simple optical cuvette, consisting of a spiral of polythene tubing, is described for use in any photoelectric colorimeter for the oximetry of whole blood. The method is reliable and rapid, and requires only 0-5 ml. blood. REFERENCES Handforth, C. P. (1953) J. Physiol. 120, 43P. Millikan, A. (1942) Rev. sci. Instr. 13, 434. Van Slyke, D. D., Neil, J. M.

Findings
I have
kept detailed records of about 2300 patients, chiefly ex-Servicemen, involving about 2800 endoscopies between November, 1946, and July, 1954 : 11 of these presented with granular proctitis associated with ulcerative colitis, 7 with granular proctitis following amoebic dysentery, and 26 with the idiopathic granular proctitis. Although 21 of these 26 patients had served in the" tropics, and most of them had been labelled " dysentery at some time in their service, careful study of their
and repeated sigmoidoscopies and stool examinaprovided convincing evidence of a non-dysenteric picture.

Treatment
It is my impression that phthalylsulphathiazole suppositories (Cluer 1947) have a place, albeit small, in controlling idiopathic granular proctitis. It is true that, since no infective agent has been incriminated, the Plain cocouse of an antibacterial drug is empyrical. butter suppositories are probably just as effective, and it is worth prescribing these, particularly in periods of quiescence. Although severe secondary anaemia was not observed in this series it can develop (B. N. Brooke, personal communication) and would indicate iron therapy. Probably the most valuable part of the
in all 4 cases was about four years. The follow-up letters show that in no case was the patient obliged to lose more than an occasional week’s work : thus even in cases with a six-year history no gross deterioration has taken place. In case 21 the disease has lasted more than thirty years without causing much inconvenience to the patient. It is important that this syndrome should be clearly defined and kept in mind whenever rectal bleeding is If it can be diagnosed with under consideration. precision, the patient can be assured that his disease is comparatively harmless ; this is of great importance because rectal bleeding usually fills the patient with alarm and apprehension, and he is likely to torture himself with possibilities which he hardly dares to mention. There c-,n be no doubt whatever that a very large number of patients with idiopathic granular proctitis were hastily and uncritically diagnosed as having some form of tropical dysentery and treated as such. Indeed tracing back the history of such cases leads one into a tangle of vague diagnoses which in retrospect is impossible to unravel. The upshot of this is that, if the syndrome were widely recognised, the evacuation of personnel from forward areas would be minimised, and many an innocent victim

Summary 26 cases of idiopathic granular proctitis are reviewed. The recognition of this syndrome is important, so that it can be clearly distinguished from the more serious conditions of which it may be a forerunner, a concomitant, or a
sequel.
I wish to thank Mr. B. N. Brooke for his advice during the preparation of this article. Seeing that war pensioners’ medical documents have been used, it is fitting that acknowledgment should be made to the Ministry of Pensions and National Insurance for permission to use these records. REFERENCES
