[Exploration of biliary tracts for laparoscopy for treatment of choledocholithiasis]. / Exploración de vías biliares por laparoscopia para el tratamiento de la coledocolitiasis.

BACKGROUND: Common bile duct stones are found in approximately 16% of patients undergoing laparoscopic cholecystectomy. If the diagnosis of choledocholithiasis is made in the preoperative work-up it is a common practice to refer patients to endoscopic retrograde cholangiography and endoscopic sphincterotomy. However, if the diagnosis is established during the intraoperative cholangiogram the surgeon confronts a therapeutic dilemma between laparoscopic common bile exploration, conversion to open surgery or post-operative endoscopic sphincterotomy. OBJECTIVE: We have opted to resolve the choledocholithiasis in only one session during the laparoscopic cholecystectomy, with the transcystic common bile duct exploration technique using the choledochoscope, or with laparoscopic choledochotomy. We report our early experience in terms of success of stone removal, operative time, morbidity, mortality and hospital stay. METHODS: from 1992 to 2003 we performed 460 laparoscopic cholecystectomies and using selective cholangiography in 138 patients (30%) we found 52 patients with common bile duct stones, for an incidence of 11.3%. RESULTS: Of this group we performed laparoscopic common bile duct exploration in 46 patients, and our success rate for stone removal was 95.6% (44 of 46) with only two failures related to multiple stones and impactation at the ampulla for a conversion rate of 4%. The mean operative time was 120 +/- 40 min. A morbidity of 8.6% was found, with no mortality. Hospital stay was 48 hrs. Mean recovery time was 7 days, and time to return to work 15 +/- 3 days. CONCLUSIONS: We concluded that must of the patients with common bile duct stones found during laparoscopic cholecystectomy can be treated with success using the laparoscopic technique with choledochoscopy, without increased morbidity or mortality, and with a short hospital stay and recovery time similar to patients in whom only laparoscopic cholecystectomy is perform. According to our results we encourage that this method should become the primary strategy in the great majority of patients with common bile duct stones found during intraoperative cholangiography.

Transcystic common bile duct exploration in the management of patients with choledocholithiasis.

Common bile duct stones are found in approximately 16% of patients undergoing laparoscopic cholecystectomy. If the diagnosis of choledocholithiasis is made at the preoperative workup, it is common practice to refer the patient for endoscopic retrograde cholangiography and endoscopic sphincterotomy. However, if the diagnosis is established during intraoperative cholangiography, the surgeon is confronted with a therapeutic dilemma-that is, the choice between laparoscopic common bile duct exploration, conversion to open surgery, or postoperative endoscopic sphincterotomy. We have opted to treat patients with choledocholithiasis in only one session during the laparoscopic cholecystectomy; we use the transcystic common bile duct exploration technique employing the choledochoscope. We report our early experience in terms of success of stone removal, operative time, morbidity and mortality, and length of hospital stay. From 1992 to 2002, we performed 350 laparoscopic cholecystectomies. Selective cholangiography was used in 105 patients (30%); 40 of them were found to have common bile duct stones, for an incidence of 11.4%. Among this group, we performed laparoscopic transcystic common bile duct exploration in all but six patients. Our success rate for stone removal was 94.1% (32 of 34 patients), with only two failures related to multiple stones and impaction at the ampulla, for a conversion rate of 5.8%. The mean operative time was 120+/-40 minutes. The morbidity rate was 8.8%, and there were no deaths. Length of hospital stay was 24 to 48 hours. Mean recovery time was 7 days, and time to return to work was 15+/-3 days. We concluded that most of the patients with common bile duct stones found during laparoscopic cholecystectomy could be treated successfully by means of the transcystic technique with choledochoscopy, with no increase in morbidity or mortality and a shortened hospital stay and recovery time, similar to patients who undergo only laparoscopic cholecystectomy. On the basis of our results, we recommend that this method become the primary strategy in the great majority of patients with common bile duct stones found during intraoperative cholangiography.

Un caso de hemartoma de glándulas de Brunner como causa de hemorragia de tubo digestivo / Case report of Brunner's gland hamartoma as a cause of upper gastrointestinal bleeding

Mujer de 26 años con un cuadro clínico de síndrome anémico, vómito postprandial y melena intermitente de seis meses de evolución. La homoglobina de ingreso fue de 3.5 g/dL. El estudio endoscópico mostró un tumor que ocupaba el 90 por ciento de la luz duodenal. Se tomaron biopsias que se informaron como duodenitis aguda y crónica erosiva. Con diagnóstico de probable leiomioma, se efectuó laparotomía exploradora con duodenotomía y se resecó un tumor pedunculado que correspondió a un hamartoma de glándulas de Brunner. Esto ocasionó obstrucción duodenal parcial y hemorragia del tubo digestivo, los dos síntomas más comunes de este tumor raro
