Recurrence of gall-stone ileus in the immediate post-operative period has been reported only very occasionally (Brockis and Gilbert, 1957; Grey Turner, 1932; Hand and Gilmore, I943; Foss and Summers, I942) and is usually the result of missing a second stone in the small bowel at the first operation. Recurrence after months or years is exceptionally rare and is due to further stones finding their way into the bowel from the gallbladder. This paper reports 13 cases of gall-stone ileus, including two cases of recurrence, one after nine years (Case i) and one after three months (Case 6 and 6a), and three cases in which two stones were found in the small intestine at operation (Cases 3, Io and 13). The three cases illustrate obstruction by the proximal of two stones (Case io), obstruction by the distal of two stones (Case 13), and closed loop obstruction between two impacted stones (Case 3).The cases are briefly set out in the table. They were admitted to the Norfolk and NorwichHospital in a Io-year-period, April 1948 to March I958.
Discussion IncidenceThere were 13 cases of gall-stone ileus in a Io-year period representing about i per cent. of all cases of intestinal obstruction. In the same period mesenteric infarction was three times and volvulus six times as common as gall-stone ileus. Vick (I932) found 2 per cent. of a large series of all types of obstruction to be due to gall-stones. However, as has been pointed out, nearly 25 per cent. of all small bowel obstructions in patients over 70 years of age, excluding strangulated herniae, were due to gall-stone ileus in his 1925-30 series.The equivalent figure for women alone would obviously be even higher. Age and SexThe average age of the patients in this series was 7I. The range was 43 to 86 and o1 of the 13 cases were over 70.There were 12 women and one man.
MortalityFour deaths out of 13 cases give a mortality of 31 per cent., roughly the same as in a collected series I940-56 by Brockis and Gilbert (I957) but less than half Vick's (1932) figure of 70 per cent.for 1925-30. Recurrence Case i was relieved of obstruction by gall-stone in the ileum nine years previously in the same hospital and made an excellent recovery. There was no mention in the operation note of that time about the gall-bladder area, and on subsequent follow-up the patient was symptom free and cholecystectomy was not advised. The patient was again successfully treated by operation for this second attack of gall-stone ileus, and again there was no mention in the operation note of the gallbladder. Presumably, in view of her age (70), interval cholecystectomy was not advised.Case 6 made a satisfactory recovery after her operation on 26.7.52, when an obstructing stone in the ileum was removed. At this operation a hard mass obscured by adhesions was palpable in the gall-bladder region. The patient was readmitted three months later with a recurrent gallstone obstruction, the stone being impacted in the jejunum 3 ft. below the duodeno-jejunal flexure.The operation was difficult because of adhesions, a...
