Comparison of percutaneous and endoscopic retrograde removal of postoperatively retained bile duct stones.
Forty-one patients underwent nonsurgical removal of postoperatively retained bile duct stones in two nonrandomized groups. The endoscopic-retrograde technique was used in 21 patients, and succeeded in 19. The percutaneous approach through the T-tube tract was used in 22 patients, including the two in whom endoscopic stone removal had failed, and was successful in 21 patients. Individual preferences and prior history introduced a selection bias against the percutaneous technique. Auxiliary extracorporeal shockwave lithotripsy (ESWL) was used in 2 patients whose stones could not be fragmented mechanically by the percutaneous basket technique. ESWL was successful in one patient but failed in the second. Because endoscopy had also failed in this case, the patient subsequently underwent repeat surgery. Procedure-related complications were minor with both techniques and were readily treated by conservative measures. We conclude that both the retrograde and the percutaneous approaches are effective and safe. The endoscopic approach appears convenient because there is no need to await maturation of the percutaneous tract, but sphincterotomy carries a small but distinctive risk. Because the percutaneous approach uses an existing tract, is only minimally invasive and leaves the sphincter of Oddi intact, it is preferable in those patients who have T-tubes of appropriate size and position in place.

Pre-, intra- and postoperative staging of gastric carcinoma and clinical outcome.
BACKGROUND: We compared preoperative (combined clinical and radiological staging and endoscopical Borrmann classification), intraoperative (by the surgeon: curative/palliative; R0/R1/R2-resection; intraoperative stage I to IV) and postoperative staging including histological results (pTNM) in respect of resectability and prognosis. METHODS: All patients with adenocarcinoma of the stomach were prospectively and consecutively included in the study protocol and were staged during the hospitalisation by the different specialists. Out of 215 patients with malignant tumors of the stomach, 153 were finally evaluated for the study. We excluded 62 patients with other malignancies or with a follow up of less than 6 months. Preoperative endoscopic Borrmann classification was done by the gastroenterologist, preoperative TNM-classification by the radiologist and surgeon, intraoperative classification by the surgeon and postoperative classification by the pathologist. All results were immediately described in the protocol. Follow-up and survival curves were performed by the Regional Tumor Registry and statistics by the Statistical Department of the University using Kaplan-Meier survival curves and Log-Rank and Wilcoxon Test for significance. RESULTS: Preoperative staging was unreliable and there was no relationship between preoperative and postoperative staging nor survival. In opposite intra- and postoperative staging correlated significantly between the different groups and with survival (p < 0.001). CONCLUSIONS: As long as preoperative staging systems are not improved (which may be in the future the case with endosonography), all operable patients with gastric carcinoma should undergo a laparotomy or laparoscopy, because only intraoperative evaluation of the surgeon allows a decision on a possible curative resection. Patients with stages I-III should be resected radically with complete dissection of lymph node compartments 1 and 2. This policy is justified especially in view of a minimal hospital mortality (3%).
