Natural history of asymptomatic gallbladder stones in clinic without beds: A long-term prognosis over 10 years.

BACKGROUND

Several studies have explored the long-term prognosis of patients with asymptomatic gallbladder stones. These reports were primarily conducted in facilities equipped with beds for addressing symptomatic cases.

AIM: To report the long-term prognosis of patients with asymptomatic gallbladder stones in clinics without bed facilities.

METHODS

We investigated the prognoses of 237 patients diagnosed with asymptomatic gallbladder stones in clinics without beds between March 2010 and October 2022. When symptoms developed, patients were transferred to hospitals where appropriate treatment was possible. We investigated the asymptomatic and survival periods during the follow-up.

RESULTS

Among the 237 patients, 214 (90.3%) remained asymptomatic, with a mean asymptomatic period of 3898.9279 ± 46.871 d (50-4111 d, 10.7 years on average). Biliary complications developed in 23 patients (9.7%), with a mean survival period of 4010.0285 ± 31.2788 d (53-4112 d, 10.9 years on average). No patient died of biliary complications.

CONCLUSION

The long-term prognosis of asymptomatic gallbladder stones in clinics without beds was favorable. When the condition became symptomatic, the patients were transferred to hospitals with beds that could address it; thus, no deaths related to biliary complications were reported. This finding suggests that follow-up care in clinics without beds is possible.
