Improving the outcome in gallstone ileus

Gallstone ileus as a cause of upper intestinal obstruction

Gallstone ileus, a mechanical intestinal obstruction caused by the passage of a gallstone into the intestinal lumen through a fistula, although not common, deserves to more carefully studied due to its morbidity and mortality. Its incidence among older-age groups explains its association with chronic and degenerative diseases, which increase the complexity of the treatment choice. The need and appropriateness of a surgical approach to a cholecystenteric fistula to solve the obstructive emergency, in a one or two stage procedure, has been discussed in the literature. It has also been reported that gallstone ileus is an uncommon cause of upper intestinal obstruction. Intestinal obstruction is seen more frequently after a gallstone impacts at the ileocecal valve. The authors report a case of gallstone ileus as a cause of upper intestinal obstruction and discuss its diagnosis and treatment.

Gallstone ileus: a new role for abdominal computed tomography

This case report illustrates the difficulties in making the clinical diagnosis of gallstone ileus. In addition to an unusual clinical picture, the changes normally expected on abdominal X-ray in gallstone ileus were subtle and missed in our patient. The diagnosis was made using abdominal computerised tomography (CT). We recommend the early use of abdominal CT scanning in the investigation of clinical bowel obstruction, especially in the elderly, where gallstone ileus is a more common condition.

Gallstone ileus resulting in strong intestinal obstruction

Mechanic intestinal obstruction, caused by the passage of biliary calculus from vesicle to intestine, through fistulization, although not frequent, deserve study due to the morbi-mortality rates. Incidence in elder people explains the association with chronic degenerative diseases, increasing complexity in terms of therapy decision. Literature discusses the need and opportunity for the one or two-phase surgical attack of the cholecyst-enteric fistule, in front of the resolution on the obstructive urgency and makes reference to Gallstone Ileus as an exception for strong intestinal obstruction. The more frequent intestinal obstruction observed is when it occurs a Gallstone Ileus impacting in terms of ileocecal valve. The authors submit a Gallstone Ileus manifestation as causing strong intestinal obstruction, discussing aspects regarding diagnostic and treatment.

Gallstone ileus: post cholecystectomy

A case of gallstone ileus occurring 5 months after laparoscopic cholecystectomy is presented. The possible aetiology is discussed and the literature regarding consequences of intraperitoneal stone spillage reviewed.

Laparoscopic treatment of gallstone ileus: a case report and review of the literature

We report our experience with laparoscopic surgical treatment of gallstone ileus, along with cholecystectomy and repair of a cholecystoduodenal fistula. The technique and advantages are discussed. To our knowledge, this is the first such case done laparoscopically to be reported in the world literature.

Gallstone ileus

Thirty-seven patients (33 women and four men, median age 78 years) were operated on for gallstone ileus over a 12-year period with a median follow-up of 6.2 years. Twenty-three patients (62 per cent) had serious concomitant diseases. Plain abdominal radiographs performed at admission were diagnostic in only 17 patients (46 per cent) and other procedures such as ultrasonography, gastrointestinal contrast studies and computed tomographic scan were required in ten patients (27 per cent). The diagnosis was made before operation in 27 patients (73 per cent) but in only 17 (46 per cent) at admission. Obstructing stones were located in the terminal ileum in 27 patients (73 per cent), in the proximal ileum or jejunum in five (14 per cent), in the duodenum in two (5 per cent), and in the colon in three (8 per cent). In six instances (16 per cent), more than one stone was involved. Cholecystduodenal fistula was the most frequent fistula type (n = 25, 68 per cent), followed by cholecystcolonic (n = 2, 5 per cent) and cholecystduodenocolonic (n = 2, 5 per cent) types. The site of the fistula was not established in the other eight instances. A one-stage procedure consisting of the removal of the impacted stone, fistula repair and cholecystectomy was performed in eight patients, two of whom died. A second group of six patients underwent a two-stage procedure consisting of enterolithotomy followed by elective biliary surgery, with no mortality. Removal of impacted stones was the only surgical treatment in the remaining 23 patients, with five deaths. Operative mortality and morbidity rates associated with the initial procedure did not differ significantly among the three therapeutic groups, which were comparable in terms of patient age, associated concomitant diseases and APACHE II score. However, later biliary complications were prominent in patients treated only by enterolithotomy. These results support the view that a one-stage procedure is, when feasible, a valid option and may be the procedure of choice. When local or surgical conditions argue against a one-stage procedure, biliary surgery at a second stage should be considered, if residual stones are present. In poor risk patients, non-operative methods should be considered.

Shock-wave therapy of gastric outlet syndrome caused by a gallstone

A patient with gastric outlet syndrome (Bouveret's syndrome) caused by a large gallstone impacted in the duodenal bulb was successfully treated by extracorporeal shock-wave lithotripsy. Thus, open abdominal surgery could be avoided. For disintegration of the stone, three consecutive lithotripsy procedures were necessary. Thereafter, stone fragments could be extracted endoscopically. Extracorporeal shock-wave lithotripsy could become a non-surgical alternative in patients with obstruction of the duodenum caused by a gallstone.

Multivisceral intestinal transplantation: surgical pathology

We report the diagnostic surgical pathology of two children who underwent multivisceral abdominal transplantation and survived for 1 month and 6 months. There is little relevant literature, and diagnostic criteria for the various clinical possibilities are not established; this is made more complicated by the simultaneous occurrence of more than one process. We based our interpretations on conventional histology, augmented with immunohistology, including HLA staining that distinguished graft from host cells in situ. In some instances functional analysis of T cells propagated from the same biopsies was available and was used to corroborate morphological interpretations. A wide spectrum of changes was encountered. Graft-versus-host disease, a prime concern before surgery, was not seen. Rejection was severe in 1 patient, not present in the other, and both had evidence of lymphoproliferative disease, which was related to Epstein-Barr virus. Bacterial translocation through the gut wall was also a feature in both children. This paper documents and illustrates the various diagnostic possibilities.
