Acute gallbladder volvulus: laparoscopic treatment in an infant

Introduction

Gallbladder volvulus is a rare and difficult to diagnose pediatric entity, its delayed treatment leads to complications. A 9 months old male case solved by laparoscopy is reported.

Case report

Twelve hours of development with irritability, vomiting and fever. Painful abdomen, leukocytosis and ultrasound with perivesicular fluid. Computed tomography revealed cystic bending, increased density and reinforcement of contrast medium. Gallbladder was found volvulated and necrotized by laparoscopy.

Discussion

It is a very rare disease. A 9 months old baby was reported in whom a minimally invasive approach allowed diagnosis and safe treatment.

Association between cholesterol gallstones and testosterone replacement therapy in a patient with primary hypogonadism

A 16-year-old boy had a past medical history of primary hypogonadism, due to bilateral anorchia. He presented with gallstones located in the gallbladder and a mild dilatation of the intrahepatic biliary tree. The histology study reported cholesterol gallstones. The patient had been treated with testosterone replacement therapy since infancy. We suggest a possible correlation between testosterone replacement therapy and the presence of cholesterol gallstones.

[Neuroendocrine small-cell carcinoma of the gallbladder. An unexpected finding after diagnostic laparoscopy]

BACKGROUND

Gallbladder cancer ranks fifth among oncological diseases affecting the gastrointestinal tract; nevertheless, it is the world's most common malignant tumor of the bile ducts. It is usually diagnosed after cholecystectomy and tends to have bad prognosis. Adenocarcinoma is the main histological finding, although other rare histologic types have been described among the actual literature. Poorly differentiated squamous-cell neuroendocrine gallbladder carcinoma is an extremely rare neoplasm. A poor prognosis is associated with this histological type.

AIM

The aim of this paper is to show that performing a systematic exploration of the entire peritoneal cavity in all laparoscopic surgeries can lead to find completely unexpected changes related to an unidentified disease. Also, a detailed review of our unexpected finding is made: The neuroendocrine small cell carcinoma of gallbladder.

CLINICAL CASE

We hereby report the case of a 40-year-old patient with a ruptured ectopic pregnancy that underwent emergency laparoscopic surgery, presenting the incidental finding of a small-cell carcinoma of the gallbladder.

CONCLUSIONS

Our surgical group advised that by introducing the laparoscope, the entire peritoneal cavity must be systematically reviewed, in search of differential diagnoses and unidentified pathologies. We must use the diagnostic and therapeutic qualities of laparoscopy. Bile duct endocrine tumors tend to remain silent until advanced stages, making the prognosis usually unfavorable, especially when they are unresectable. Endocrine neoplasias of the gallbladder, although uncommon, should be taken into account as possible diagnoses due to its therapeutic and prognostic implications.

[Ultrasound of gallbladder and bile duct]

The cystic nature of the gallbladder and bile duct when dilated, and the advantages of ultrasound as a quick, reproducible, convenient, cheap and low risk technique, with a high sensitivity and specificity, make it the most eligible technique in biliary pathology studies. Ultrasound has become a valuable tool for doctors studying biliary pathology and its complications, from abnormal liver function results, right upper quadrant pain, or jaundice, to cholelithiasis, cholecystitis, or suspicion of biliary tumors.
