Objectives: Indications for cholecystectomy have changed dramatically over the past three decades. Cystoisospora belli has been reported in cholecystectomy specimens of immunocompetent patients. The present study was designed to determine the prevalence and clinical association of C belli in the gallbladder.
Methods: The study included retrospective review of cholecystectomy specimens (n = 401) removed for various indications, and a prospective cohort of cholecystectomy specimens (n = 22) entirely submitted for histologic evaluation. Correlations of presence of C belli with age, sex, clinical indication, and abnormalities of preoperative laboratory values were assessed by Fisher exact test.
Results: C belli was identified in 39/401 (9.7%) of the retrospective cohort, and 6/22 (27.3%) of the entirely submitted specimens. The presence of C belli showed no correlation with age, sex, clinical indication, or laboratory abnormalities.
Conclusions: C belli resides in a latent state in the gallbladder and may be best considered a commensal organism.

Actinomycosis is a chronic, granulomatous infection caused by species, a group of anaerobic, gram-positive bacteria commonly found in the human oral cavity, gastrointestinal, and female genital tracts. Although it predominantly affects the cervicofacial region, rare manifestations such as gallbladder actinomycosis can occur. This report presents a case of gallbladder actinomycosis in a 61-year-old man who presented with a two-week history of right upper quadrant pain, jaundice, nausea, and vomiting.

Article Synopsis
- The systematic review investigates the effectiveness and cost benefits of a selective histopathology approach for cancer detection, rather than the usual routine analysis of surgical specimens.
- It analyzed data from 11 studies involving over 26,000 patients who underwent various surgical procedures, identifying a low rate of cancer diagnoses but noting substantial cost savings.
- The conclusion emphasizes that while this selective method doesn’t significantly increase missed cancer diagnoses, there are concerns regarding legal protections for surgeons who opt out of routine histopathological analysis.
Frequency of Gallbladder Carcinoma in Patients Operated for Symptomatic Cholelithiasis.

Department of General Surgery, Fauji Foundation Hospital, Peshawar, PAK.
Background Gallbladder carcinoma (GBC) is a rare but highly aggressive malignancy, often discovered incidentally during cholecystectomy for symptomatic cholelithiasis. Despite significant geographic variation, the association between gallstones and GBC is well-documented, with chronic inflammation from gallstones potentially contributing to carcinogenesis. Objective This study aims to determine the prevalence of incidental GBC in patients undergoing cholecystectomy for symptomatic cholelithiasis at a tertiary care hospital in Peshawar, Pakistan.
