Endoscopic treatment of difficult choledocholithiasis

Common bile duct stones can be treated with normal endoscopic techniques. Where stones cannot be removed due to their size or number or due to stenosis of the common bile duct, a plastic stent can be inserted, enabling rapid drainage of bile. At the three-month check-up complete removal of the stones was found in 41 (85.4%) of the 48 patients with difficult choledocholithiasis. In the remaining 7 patients (14.6%), the stent in any case resulted in clinical improvement. A permanent stent was necessary in 4 patients, enabling safe drainage with no complications. The use of endoscopy for stent placement was effective in all our cases of difficult coledocholithiasis without any complications.

Biliary duct injuries in the laparoscopic era: our experience

Aim. The main aim of our study is to evaluate the incidence, the type, the causes and the therapy of biliary duct injuries which occurred after the video laparoscopic cholecystectomies performed in our Department during the period from 1990 to 2012. Patients and methods. A retrospective analysis of 1186 VLC has been made in our Department from March 1990 to June 2012. Before the cholecystectomy all patient were evaluated with trans abdominal echography. Beyond the incidence of BDI was evaluated damaging mechanism, etiology, therapy and time of diagnosis. Results. From 1990 to 2012 a total of 9 BDIs occurred, with an incidence of 0,75%. Out of 9 patients 4 had major lesions and 5 had minor lesions; the most common BDI was Strasberg A (45%), the most common etiology was the presence of anatomical variations. In four cases the diagnosis has been intraoperative, in five cases has been postoperative. Conclusions. Our clinical experience shows that the main cause of BDI are the surgeon experience and the bile ducts anatomical variation.

Prosthetic carotid bypass graft for in-stent restenosis performed for post-endarterectomy recurrent stenosis: technical details

Aim. Carotid artery stenting (CAS) is the treatment of choice for recurrent stenosis after carotid endarterectomy (CEA). However a significative incidence of in-stent restenosis could be occurred. Despite classical CEA leads to good results, in selective cases bypass graft may be the best treatment of in-stent restenosis. Case reports. We describe two cases of carotid bypass graft performed to treat a recurrent in-stent stenosis after CAS for post-CEA restenosis. No death and cardiac complication occurred and no cranial nerves impairment was detected. Conclusion. Prosthetic bypass graft is safe and effective in treatment of in-stent recurrent restenosis after CEA restenosis.

Complications after laparoscopic Roux-en-Y gastric bypass: a diagnostic challenge. Report of three cases and review of the literature

The number of Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) procedures for morbid obesity and type 2 diabetes mellitus will increase worldwide, and therefore, an increase in perioperative morbidity can be anticipated. The authors present three cases based on different complications after LRYGB to demonstrate the diagnostic challenge that clinicians face in this particular group of patients. Also, a review of the literature covering the value of different imaging in these particular cases is provided by the authors. The role of imaging in the diagnostic process is discussed.
