Anwendungsm�glichkeiten der intraoperativen Sonographie

1983

Sonographie, Computertomographie, Angiographie und endoskopisch retrograde Cholangiopancreaticographie haben sich in der Allgemein- und Gefaschirurgie als wertvolle Untersuchungsmethoden etabliert. Schwierigkeiten bestehen jedoch manchmal in der Korrelation der Praoperativen Befunde mit dem intraoperativen Befund. Hier ist das Anwendungsgebiet der intraoperativen Sonographie (IOS) zu sehen. Sie bietet dem Chirurgen eine zusatzliche Information durch Darstellung von pathologischen Gefasprozessen, Kontrolle von Gefasanastomosen, intraoperative FlowMessung in Gefasen, Lokalisationsdiagnostik in parenchymatosen Organen. Die intraoperative Sonographie ist somit ein neues Instrument des Chirurgen…

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.

Emotional status and fear in patients scheduled for elective surgery during COVID-19 pandemic: a nationwide cross-sectional survey (COVID-SURGERY)

2021

Abstract Background Fragmented data exist on the emotional and psychological distress generated by hospital admission during the pandemic in specific populations of patients, and no data exists on patients scheduled for surgery. The aim of this multicentre nationwide prospective cross-sectional survey was to evaluate the impact of pandemic on emotional status and fear of SARS-CoV-2 contagion in a cohort of elective surgical patients in Italy, scheduled for surgery during the COVID-19 pandemic. Results Twenty-nine Italian centres were involved in the study, for a total of 2376 patients surveyed (mean age of 58 years ± 16.61; 49.6% males). The survey consisted of 28 total closed questions, in…

Ösophagusresektion bei unspezifischer Motilitätsstörung der Speiseröhre - Bedeutung der neuropathologischen Befunde

2005

A 47-year-old patient presented with a history of dysphagia for solid food for almost 10 years and weight loss of more than 50 kg. Non-resecting surgical as well as endoscopic procedures (laparoscopic cardiomyotomy with secondary antireflux operations, balloon dilation, Botulinum-toxin injection) were without success. A barium esophagogram showed a confinement of the distal esophagus with a filiform passage of the contrast medium and undigested food in the prestenotic dilated esophageal corpus. Manometry displayed a hypertensive lower esophageal sphincter with a resting pressure of 43.8 mmHg - although completely relaxing. The tubular esophagus was aperistaltic with 100 % simultaneous and r…

Pathology Reporting of Resected Pancreatic/Periampullary Cancer Specimen

2018

Pancreatic specimens have always been a great challenge for surgical pathologists due to their anatomic complexity and the difficulty of becoming familiar with these specimens. However, pancreatic specimens are becoming more and more common in many hospitals because of the improvements in surgical techniques and perioperative care that have dramatically reduced the postoperative mortality rate.

Interventional and surgical modalities of treatment for pulmonary arterial hypertension

2004

AbstractBeyond medical therapy, different interventional and surgical approaches exist for treatment of pulmonary arterial hypertension (PAH). Atrial septostomy has been applied in patients with lack of response to medical therapy in the absence of other surgical treatment options. With growing experience, procedure-related death rates have been reduced to 5.4%, and the most suitable patient group has been identified among patients with a mean right atrial pressure between 10 and 20 mm Hg. Pulmonary endarterectomy is the accepted form of treatment for patients with chronic thromboembolic pulmonary hypertension. Establishing the diagnosis and the classification of the type of lesions by pulm…

Chirurgische Therapie von Lebermetastasen kolorektaler Karzinome

2003

Resection is the only curative treatment of colorectal liver metastases proofed by a long-term follow-up. The operation is indicated if the metastases are completely removable with sufficient liver parenchyma remaining after resection and if the patient is fit for surgery. The resection is not indicated in cases with non resectable extrahepatic tumours and lymph node metastases distal the hepatoduodenal ligament. The postoperative mortality amounts to about 5 % and the 5-year-survival-rates range between 20 and 40 % depending on the selection of patients. Aims of new concepts of operative therapy are the improvement of resectability by preoperative portal vein embolization, the resection co…
