Unusual Presentation of Recurrent Gallstone Ileus: A Case Report and Literature Review. Case Rep Gastrointest Med. 2019;2019:8907068. [PMID: 31687227 PMCID: PMC6794980 DOI: 10.1155/2019/8907068]

Two Sites of Obstruction with Gallstones: A Case Report of Bouveret Syndrome with a Concurrent Biliary Ileus

Bouveret syndrome is a gastric outlet obstruction, and biliary ileus is an obstruction of the small bowel, and both are caused by a gallstone that escaped the gallbladder through a bilio-enteric fistula. The concurrent occurrence of obstruction at both sites is encountered very rarely, and only two such cases associated with Bouveret syndrome were reported before. We now present a case involving a 78-year-old female with simultaneous obstruction at both the duodenum and jejunum. The literature is reviewed to evaluate the incidence of such a situation and to discuss the management of the case.

The Regularity of the Site of Impaction in Recurrent Gallstone Ileus: A Systematic Review and Meta-Analysis of Reported Cases

Objective

Due to the rarity of recurrent gallstone ileus (RGSI), its epidemiological and clinical features are elusive. With a focus on mortality and the site of impaction, this study consolidates the key clinical characteristics of index GSI (IGSI) and RGSI.

Methods

A meta-analysis of cases reported on RGSI was performed. Risk factors for mortality and site of impaction were examined, and a subgroup analysis was performed for age, sex, and site of impaction (jejunum, ileum, or others).

Results

In the final analysis, 50 (56 individual cases) studies were included. The paired data for the site of impaction was available for 45 patients. Women accounted for 87.3% of all RGSI cases included in the pooled analysis. The median age (interquartile range, IQR) of the patients was 70 (63-76) years, and the median time of recurrence (IQR) was 20.5 (8.5-95.5) days. The overall mortality rate was 11.8%, without correlation between the mortality rate and age, the time of recurrence, or the site of impaction. The region in which the stone was found in RGSI and IGSI was similar in most cases (p=0.002). Logistic regression also revealed a higher probability of stone impaction in the ileum in RGSI if it was the site of impaction in IGSI. In most cases, enterolithotomy was the preferred method.

Conclusions

A high index of suspicion for RGSI should be maintained for older women with a history of GSI. The region where the stone was impacted during IGSI should be investigated first in such patients.

Rare recurrent gallstone ileus: A case report

BACKGROUND

The management of recurrent gallstone ileus (GSI) is unsatisfactory, and there is no consensus on how to reduce the incidence of recurrent GSI.

CASE SUMMARY

A 79-year-old man presented to the Emergency Department of our hospital complaining of abdominal pain. An abdominal computed tomography (CT) scan revealed cholecystolithiasis, intrahepatic bile duct dilatation, gas accumulation, small intestinal obstruction, and circular high-density shadow in the intestinal cavity. Emergency surgery revealed that the small intestine had extensive adhesions, unclear gallbladder exposure, obvious adhesions, and difficult separation. The obstruction was located 70 cm between the ileum and the ileocecum, which was incarcerated by gallstones, and a simple enterolithotomy was carried out. On the third day after the operation, he had passed gas and defecated and had begun a liquid diet. On the fifth day after the operation, he suddenly experienced abdominal distension and discomfort. Emergency CT examination revealed recurrent GSI, and the diameter of the stone was approximately 2.0 cm (consistent with the shape of cholecystolithiasis on the abdominal CT scan before the first operation). The patient’s symptoms were not significantly relieved after conservative treatment. On the ninth day after the operation, emergency enterolithotomy was performed again along the original surgical incision. On the twentieth day after the second operation, the patient fully recovered and was discharged from the hospital.

CONCLUSION

We believe that a thorough examination of the bowel and gallbladder for gallstones based on preoperative imaging during surgery and removal of them as far as possible on the premise of ensuring the safety of patients are an effective strategy to reduce the recurrence of GSI.
