IntroductionGallbladder torsion is a rare entity, which is often difficult to diagnose preoperatively. Since its first description in 1898 by Wendel, there have been over 500 documented cases in the literature. It is defined as rotation of the gallbladder on its mesentery along the axis of the cystic duct and cystic artery. Gallbladder torsion is more frequently encountered in the elderly with peak incidence in the 65-75 year old group, and a 3:1 female predominance. Gallbladder torsion typically presents as an acute abdomen requiring emergency surgery, and most cases are found as a surprise at surgery since preoperative diagnosis of gallbladder torsion is difficult. We report a case of acute gallbladder torsion in an elderly male and review the clinical aspect of gallbladder torsion.Case reportA 54-year old male presented to our department with a 5-day history of sudden onset colicky abdominal pain associated with vomiting, progressive abdominal distension and fever. Laparotomy through a chevron incision was performed and findings at operation included a gallbladder, which was necrotic and gangrenous, not attached to the liver by any mesentery. It was hanging by the attachments of cystic duct and cystic artery only, with a 360-degree clockwise torsion.ConclusionGallbladder torsion is rare surgical emergency which requires a high index of suspicion for early preoperative diagnosis and prompt intervention. Treatment consists of cholecystectomy with a prior detorsion to avoid injury to the common duct.

Lymphoepithelial cysts are rare pancreatic lesions of undetermined pathogenesis. The literature on this entity is limited to case reports or small series. We describe a case of 66 year male, incidentally diagnosed as lymphoepithelial cyst of pancreas that was managed by enucleation. This is the first case report of lymphoepithelial cyst from India. An extensive Medline search was carried out for lymphoepithelial cyst of pancreas. Till date less than 100 cases were identified in available literature. All these cases (including our case) were analyzed. This entity has uniform and distinctive clinicopathological features. About half of the reported cases were asymptomatic with most of the lesions diagnosed incidentally. Majority of patients presents with non-specific symptoms making preoperative diagnosis difficult. Lymphoepithelial cyst of the pancreas is a rare benign lesion, which is difficult to diagnose preoperatively. High index of suspicion and preoperative fine needle aspiration cytology may help in making diagnosis and avoiding surgery in asymptomatic patients.

IntroductionPeritoneal loose bodies, or peritoneal mice, are rare asymptomatic lesions that are usually found as an incidental finding during abdominal surgery or autopsy. Giant loose bodies, measuring more than 5 cm, are rare and only a few cases are reported in the literature. These bodies are usually infarcted appendices epiploicae, which become detached and appear as a peritoneal loose body in the abdominal cavity. They may re-attach themselves to a surface, such as the lower aspect of the spleen or omentum, in which case they can be called a "parasitized peritoneal body", as in our case.Case PresentationWe report a case of a giant loose peritoneal body measuring 7 × 5 cm found incidentally in a 64-year-old Indian man who presented with acute intestinal obstruction. We present the current hypothesis and our opinion on the genesis of such large bodies and discuss the problems in diagnosis.ConclusionPeritoneal loose bodies are common but giant peritoneal loose bodies are very rare. These giant bodies usually do not require any treatment until they become complicated. Present diagnosis modalities have limitations in the diagnosis of mobile lesions in the abdominal cavity, so care must be taken to avoid unnecessary laparotomies in uncomplicated cases.

This is the first multi-centric report of peri-operative outcomes of PD from India. The results from these specialist centers are very acceptable, and appear to support the thrust towards centralization.
