RESUMO
Pancreaticolithiasis represents a rare phenomenon, being superimposed most of the time on a form of chronic pancreatitis of multifactorial etiology. Pancreaticolithiasis is a late complication of the phenomenon of chronic pancreatitis. The reverberant inflammatory process, followed by the fibrotic degeneration of the pancreatic parenchyma, and pancreatic fluid stasis at the ductal level are factors that contribute to the phenomenon of calcium precipitation. This article describes the case of a patient with a diagnosis of pancreaticolithiasis (Wirsung duct lithiasis), a phenomenon superimposed on chronic pancreatitis of ethanolic cause (Rosemont classification). It was decided to perform surgery via the classical approach with the perfection of corporeo-caudal pancreatectomy and preservation of the splenic vessels (Kimura procedure) with pancreatico-jejunal anastomosis on the Roux-en-Y loop. The aim of this study is to identify the best method of treatment for pancreaticolithiasis. To enhance the case and provide a basis for standardization, a literature review was carried out, which included a total of six articles. The results of this study highlight that, currently, the management of symptomatic pancreaticolithiasis encompasses medical therapy (enzyme replacement therapy), interventional therapy (ESWL (extracorporeal shock wave lithotripsy) ± ERCP (endoscopic retrograde cholangiopancreatography), ERCP + sphincterotomy + stent insertion, and POP (oral pancreatoscopy)), and surgical treatment. In conclusion, based on the analysis conducted in this study, the size of the calculi present determines which is the suitable therapeutic care. Unlike stones over 0.5 cm, when surgery is explicitly advised for therapeutic purposes in the absence of endoscopic techniques, stones under 0.5 cm should be treated using endoscopic procedures.
RESUMO
The aim of our study was to explore the feasibility of a novel fluorescence-guided laparoscopic technique to localize the obscure GI haemorrhage, using the vascular wash-out properties of indocyanine green (ICG). Method: The feasability study included patients with previous surgical modifications of the gut architecture, qualified as an overt obscure GI bleeding with an urgent need to be localized and controlled. Five mL of ICG was injected intravenously and laparoscopic infrared inspection was performed 30 minutes after the dye was eliminated from the bloodstream. The bleeding area mapping was demonstrated and the haemostasis was carefully performed using endoscopy or laparoscopic techniques. Results: A series of two cases were included in our fesability study so far. Case 1. A 43-year old male, who recently received a Laparoscopic Roux-en-Y gastric bypass (RYGB), developed a recurrent GI bleeding. Post dye wash-out intense signal was demonstrated at the level of duodenum and weaker at the gastric remnant. The laparoscopic trans-gastric exploration of the remnant identified an active bleeding source siding the stapled line and haemostasis was achieved with laparoscopic ligation using stitches. Case 2. A 66-year old male patient who underwent an open Whipple resection nine months before, was admitted for a repeated GI bleeding. The inspection of the biliopancreatic limb noticed an intense fluorescent signal toward the enteral proximal end. Upper digestive endoscopy confirmed the presence of an active bleeding source from ectopic jejunal varices siding the choledoco-jejunal anastomosis. Argon plasma coagulation was performed endoscopically and achieved hemostasis. Conclusions: A successful novel ICG fluorescence-guided laparoscopic mapping technique was used to localize the site of the obscure GI haemorrhage and to facilitate the prompt bleeding control. To the best of our knowledge these are the first published cases for which this technique was used.
