De novo Choledocholithiasis in Retained Common Bile Duct Stent.

De novo choledocholithiasis means formation of stone in the common bile duct (CBD). It can present as biliary colic, jaundice, cholangitis, pancreatitis or it may be asymptomatic. There are various indications for biliary stenting like CBD stone, CBD stricture, biliary leak, peri ampullary carcinoma, CBD malignancy, etc. Foreign bodies like silk sutures, endo-clips, fish bone, retained T- tubes, plastic or metallic stents, etc. lead to biliary stasis leading to eventual stone formation. Here, we discuss a case of choledocholithiasis post-cholecystectomy with CBD stenting done 15 years back which had migrated and acted as a nidus for stone formation in the CBD and hepatic duct.

Gastrointestinal stromal tumour presenting as palpable abdominal mass: A rare entity.

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumour of gastro-intestinal tract. Annual incidence of GIST in United States is approximately 3000-4000. Clinical presentation of GIST varies with location and size of tumour but GIST presenting with palpable abdominal mass is rare. We report a case of 38 years old male who presented with large abdominal lump. Computed tomography (CT) scan showed a large solid-cystic lesion encasing second part of duodenum and distal common bile duct. On CT differential diagnosis of Leiomyoma, Leiomyosarcoma and GIST were made. The diagnosis of GIST was confirmed by immune-histochemical study of the biopsy material. Patient underwent pancreaticodudenectomy. Post-operative course was uneventful. Patient was started on Imatinib therapy post-operatively. No recurrence noted at six months follow up.

A Large Cystic Variant of Gastro-intestinal Stromal Tumour arising from the Jejunum: A Case Report.

Gastrointestinal stromal tumours (GISTs) represent a mesenchymal neoplasm arising from the interstitial cells of cajal occurring mainly in the gastrointestinal tract. Here, we present a case of a large GIST arising from the jejunum with cystic presentation unlike the usual presentation as a solid mass. A 50-year-old male patient came with complaint of a painless mobile lump in abdomen of approximately 25 cm in size which had gradually increased over two years. Clinically mesenteric cyst was suspected. Intra-operatively the mass was a 30x25 cm cyst with approximately 2500 ml serous fluid present inside it arising from the anti-mesenteric border of the jejunum, adherent to the jejunum, appendix and the dome of the bladder. The fluid was aspirated and the mass excised along with resection of the involved jejunal segment and appendectomy was done. Diagnosis was confirmed on immunohistochemistry study. Imatinib Mesylate 400 mg OD was started as adjuvant therapy in view of the high risk of metastasis.

Choledocholithiasis: endotherapy versus surgery.

When multiple treatment options are available, debate invariably persists regarding the optimal option. Confusion and controversy must then be resolved based on scientific evidence, but one needs to be practical because options depend on the available expertise. We aimed to evaluate the efficacy of endotherapy vis-à-vis surgery in patients with choledocholithiasis. The records of 349 patients with stone disease from February 2005 to January 2010 were analyzed. A total of 349 patients were analyzed: 279 patients with gallstones alone, 56 with choledocholithiasis, 3 with stones with stricture, 5 with common bile duct (CBD) and pancreatic duct (PD) stones, and 6 with combined choledocholithiasis and hepatolithiasis. In the 56 patients with choledocholithiasis alone, preoperative endoscopic retrograde cholangio pancreatography (ERCP) and endotherapy were followed by cholecystectomy within 48 hours. Endotherapy was successful in 15 patients, whereas surgery was required in the remaining 41 patients. Surgery is an efficacious option and can be carried out safely with acceptable morbidity and no mortality, even in difficult situations.

Biliary complications of cholecystectomy.

Biliary complications occur because of causes such as obscure or variant anatomy, predisposing conditions such as fibrosis or severe inflammation, equipment failure, and surgeon factors. The aim of this study was to review the optimal surgical treatment. Analysis of 81 patients with bile duct injuries treated in a single referral unit over an 8.5-year period was done. Time of detection of biliary injury and its presentation were ascertained as well as the level of injury (Strasburg's). In 8 patients, injury was detected intraoperatively, and 41 were detected in the early postoperative period with bile leak (n = 25) or obstructive jaundice (n = 10). Those diagnosed in the delayed postoperative period (n = 32) presented with recurrent cholangitis (n = 9), obstructive jaundice (n = 16), and a cholestatic enzymatic profile (n = 1). Roux-en-Y hepatico-jejunostomy was the preferred option (n = 64). One patient died because of biliary peritonitis. Improper treatment is associated with disastrous results, but early recognition and correct management can lead to a successful outcome and good prognosis.
