Strategie des chirurgischen Vorgehens beim hilären Cholangiokarzinom
2006
Surgery is the decisive life-prolonging treatment in patients with hilar cholangiocarcinoma. Surgery is mainly based on empiric data. Since patients without surgery have only about 6 months to survive, to achieve a high resection rate is crucial for these patients. During diagnostic workup, percutaneous transhepatic cholangiography results in the most reliable assessment of longitudinal tumor growth. The extent of the tumor is frequently overestimated leading to the consequence of excluding the patients from surgery. En-bloc resection of the tumor and the adjacent liver should be the preferred surgical approach. So far, surgical radicality (right trisegmentectomy, extended lymphadenectomy a…
Intravesical Treatment of Superficial Urinary Bladder Tumours with Adriamycin
1980
Personal experience resulted in the observation that intravesical Adriamycin (ADM) is effective in some patients with multiple or diffuse papillary bladder tumours. A review of the literature shows that similar results have been obtained elsewhere, especially in Japan and Sweden. The response rate was higher if single doses of at least 50 mg were employed. Intravesical instillations of ADM appear to be valuable also in the treatment of carcinoma in situ and in prophylactic treatment after transurethral resection (TUR) of papillary bladder tumours.
Adriamycin Permeability of the Rat Bladder under Different Conditions
1983
Abstract Fifty female Sprague-Dawley rats were treated with 1.4 or 2.4 mg. adriamycin intravesically. Radioimmunological measurement of serum concentrations were performed up to 3 hours post-instillation in normal bladder mucosa, cystitis, and after electrocoagulation, under different filling conditions, as well as with the use of a detergent (Tween 80). The serum concentrations achieved were markedly higher after electrocoagulation or cystitis; altogether they reached only 1/6,000 of the instilled concentration. These studies on the rat bladder suggest that perioperative instillation of adriamycin to prevent recurrence is not contraindicated shortly before or after transurethral resection …
Definition of the Rectum An International, Expert-based Delphi Consensus
2019
Mini: A radiological, anatomic distinction between the rectum and sigmoid colon was agreed by consensus of international experts in rectal cancer using the Delphi Technique. Use of this landmark, “the sigmoid take-off,” may harmonize efforts in research and clinical practice to improve patient outcomes. Background: The wide global variation in the definition of the rectum has led to significant inconsistencies in trial recruitment, clinical management, and outcomes. Surgical technique and use of preoperative treatment for a cancer of the rectum and sigmoid colon are radically different and dependent on the local definitions employed by the clinical team. A consensus definition of the rectum…
nrCBF and EEG Monitoring During Probatory Balloon Occlusion of the Internal Carotid Artery
1985
Surgical treatment of tumors in the neck and throat rounding the carotid artery or of giant aneurysms originating from this vessel often makes ligation or resection of the internal carotid artery necessary. This procedure carries a 15%–30% morbidity from cerebral ischemia according to the literature (2, 7).
Impact of surgeon organization and specialization in rectal cancer outcome.
2001
Purpose The present study was designed to assess the differences in the outcome of patients with rectal cancer treated by a group of surgeons before and after being organized as a Coloproctology Unit at the same University Department of Surgery. Methods Comparison of two periods of rectal cancer surgery: I (1986–91) and II (1992–95). Period I: 94 patients were operated on by 14 general surgeons. Period II: 108 patients were operated on by only 4 surgeons of the same group organized as a Colorectal Surgery Unit after visiting referral centres abroad, adopting techniques such as total mesorectal excision (TME) for middle and low rectal cancer and washout of rectal stump. Mean follow-up during…
Can we set quality standards for the centers : minimally invasive surgery vs. open surgery in colorectal cancer resection
2020
Esta comunicación se encuentra disponible en la siguiente URL: https://www.fortunejournals.com/articles/can-we-set-quality-standards-for-the-centers-minimally-invasive-surgery-vs-open-surgery-in-colorectal-cancer-resection.pdf Background: Minimally invasive surgery (MIS) is the standard method for resection of colorectal cancer, but its indications have limitations that are constantly debated. In our study, the center had to meet the following four factors: surgeons should have considerable experience, there should be a high percentage of MIS, a low conversion rate, and good results in the intervention. Methods: Retrospective observational study of a cohort of 948 patients with colorectal c…
Lebermetastasen kolorektaler Karzinome - wie oft kann man operieren?
2007
Recurrent liver metastases of colorectal carcinoma are frequent. The repeat hepatectomy is superior to other therapeutic options. In about 20 % of patients with recurrent liver metastases a complete resection (R 0) is possible. The morbidity of repeat hepatectomy is similar to that of first hepatectomy. The 5-year survival rate after repeat hepatectomy ranges between 30 and 40 %. Often in the follow-up additional operations become necessary for extrahepatic recurrencies. For determination of the optimal therapy an interdisciplinary approach must be chosen.
676 NECESSITY OF EXTENDED LOWER PARATRACHEAL LYMPH NODE RESECTION DURING ESOPHAGECTOMY FOR CANCER
2021
Abstract Objective To evaluate the impact of lower paratracheal lymph node resection on oncological radicality and complication rate during esophagectomy for cancer. Backround The ideal extend of lymphadenectomy (LAD) in esophageal surgery is debated. Until today, there has been no proof for improved survival after standardized paratracheal lymph node resection performing oncological esophagectomy. Methods Lymph nodes from the lower paratracheal station are not standardly resected during 2-field Ivor-Lewis esophagectomy for esophageal cancer. Retrospectively, we identified 200 patients operated in our center for esophageal cancer from January 2017—December 2019. Histopathologically, 143 pat…
FA04.04: IMPORTANT STEPS AND FIRST RESULTS OF FULLY ROBOTIC IVOR-LEWIS ESOPHAGEAL RESECTION (RAMIE4) FOR ESOPHAGEAL AND ESOPHAGOGASTRIC JUNCTION CANC…
2018
Abstract Background Robotic-assisted surgery is increasing, especially in general tumor surgery. Minimal-invasive esophagectomy (MIE) is commonly the standard operation procedure in high-volume centers. Also the fully robotic minimally invasive esophagectomy using 4 robotic arms in the abdomen and thorax (RAMIE4) is performed more frequent. The advantages of RAMIE4 as well as advantages and disadvantages of special steps in the procedure and reconstruction are not clear so far and are under comparison with other MIE techniques. Methods Form January 2017 until March 2018 we prospectively collect the first 50 fully robotic RAMIE4 cases performed by one specialized surgeon and additionally the…
