Objective: To perform the first randomized controlled trial to compare laparoscopic and open liver resection. Summary Background Data: Laparoscopic resection is increasingly used for surgical treatment of tumors. However, high-level evidence conclude that superior lacking. Methods: Explanatory, assessor-blinded, single center, superiority recruiting patients from Oslo University Hospital, Oslo, Norway February 2012 January 2016. A total 280 with resectable metastases colorectal cancer were...
Background. Morbidity is a cornerstone assessing surgical treatment; nevertheless surgeons have not reached extensive consensus on this problem. Methods and Findings. Clavien, Dindo, Strasberg with coauthors (1992, 2004, 2009, 2010) made significant efforts to the standardization of morbidity (Clavien-Dindo-Strasberg classification, last revision, Accordion classification). However, classification includes only postoperative complications has two principal shortcomings: disregard...
Laparoscopic and open liver resection have not been compared in randomized trials. The aim of the current study was to compare inflammatory response after laparoscopic colorectal metastases (CLM) a controlled trial.This predefined exploratory substudy within Oslo CoMet-study. Forty-five patients with CLM were (n = 23) or 22) resection. Ethylenediaminetetraacetic acid-plasma samples collected preoperatively at defined time points during surgery snap frozen -80 C. A total 25 markers examined...
Despite the recent worldwide dissemination of laparoscopic liver surgery, no high-level evidence supports oncologic safety this approach.To evaluate long-term outcomes after versus open resection in patients with colorectal metastases.A single-center, assessor-blinded, randomized controlled trial (OSLO-COMET [Oslo Randomized Laparoscopic Versus Open Liver Resection for Colorectal Metastases Trial]). (ClinicalTrials.gov: NCT01516710).Oslo University Hospital, only provider surgery 3 million...
To analyze the immediate and long-term outcome after laparoscopic resection of colorectal liver metastases difference between observed predicted [Fong's Basingstoke Predictive Index (BPI) scores] survivals.: Laparoscopic has been reported safe feasible improves postoperative course. The oncologic outcomes are poorly reported.Between August 1998 January 2010, 122 patients underwent for during 135 procedures at Rikshospitalet. Patients undergoing surgery June 2009 were included in research...
The introduction of laparoscopic liver resection has been challenging because new and safe surgical techniques have had to be developed, skepticism remains about the use laparoscopy for malignant neoplasms. We present herein a large-volume single-center experience with resection.Retrospective study.Rikshospitalet University Hospital.One hundred thirty-nine patients who underwent 177 resections in 149 procedures from August 18, 1998, through October 14, 2008. One thirteen lesions, whom 96...
Abstract Background/purpose Laparoscopic hepatectomies have seen a worldwide proliferation. Major anatomic resections, which were initially considered unsuitable for laparoscopy, are currently confined to few centers of expertise. The aim this study was discuss the current trends and techniques in laparoscopic major hepatectomy Europe. Methods prospective databases ten European combined provide answers questionnaire that had been addressed all teams known perform liver surgery. Results...
Totally laparoscopic liver resection of lesions located in the posterosuperior segments is reported to be technically challenging. This study aimed define whether these technical difficulties affect surgical outcome.A total 220 patients underwent during 244 procedures from August 1998 December 2010. The who primary minor single for malignant tumors affecting either 1, 7, 8, and, 4a (group 1) or anterolateral 2, 3, 5, 6, and 4b 2) were included study. Seventy-five found eligible study,...
Laparoscopic liver resection is used in specialized centers all over the world. However, laparoscopic has never been compared with open a prospective, randomized trial. The Oslo-CoMet Study trial into versus for surgical management of hepatic colorectal metastases. primary outcome 30-day perioperative morbidity. Secondary outcomes include 5-year survival (overall, disease-free and recurrence-free), margins, recurrence pattern, postoperative pain, health-related quality life, evaluation...
Most treatments for cancer cause a decline in patients' health-related quality of life (HRQoL). Limiting this is universal goal healthcare providers. Using minimally invasive instead open surgical techniques might be one way to achieve this. The aim study was compare postoperative HRQoL after and laparoscopic liver resection.This predefined substudy an RCT comparing with resection. Patients colorectal metastases were assigned randomly or parenchyma-sparing assessed the Short Form 36...
Abstract Viral infections are considered as etiologic factors of subacute thyroiditis. The true incidence thyroiditis, caused by SARS‐CoV‐2 infection, is probably considerable since it often masked more dramatic affection the respiratory system. This report presents two female patients who developed de Quervain's thyroiditis after COVID‐19 disease.
Abstract Background Laparoscopic resection is regarded as safe and feasible in selected patients with benign pancreatic tumours. Few data exist on laparoscopic surgery for malignant lesions larger neoplasms unselected patients. Methods The study included all admitted to Oslo University Hospital, Rikshospitalet, from March 1997 2009 of the body tail pancreas, head, who underwent by a approach curative intent. Results A total 166 had 170 operations, including 138 resections, 18 explorations,...
Abstract Introduction Laparoscopic adrenalectomy for metastases is considered controversial. Multicenter retrospective study was performed to gain new knowledge in this issue. Materials and Methods From January 1997 till November 2008, 41 adrenalectomies were during follow‐up of the patients operated malignant tumors. The median age 64 (52–77) years. Metastases confirmed 31/41 cases. Metastatic lesions further studied define factors influencing on survival, divided sub‐groups...
Laparoscopic surgery (LS) for resectable adrenocortical carcinoma (ACC) has been questioned due to uncertainty with regard long-term oncological outcome. We analyzed the experience LS compared open (OS) at Oslo University Hospital (OUH). Material and methods. Between 1998 2011 32 patients were identified ACC stage I-III operated either by (17 patients) or OS (15 patients). Patients' records reviewed retrospectively pre- intraoperative findings, short-term surgical outcome, relapse survival....
Laparoscopic adrenalectomy is a promising alternative to open surgery although concerns exist in regard laparoscopic treatment of pheocromocytoma. This report compares the outcome and conventional (open) resection for pheocromocytoma particular intraoperative hemodynamic stability postoperative patient comfort. Seven patients laparoscopically treated (1997–2000) nine by (1990–1996) at National Hospital (Rikshospitalet), Oslo. Peroperative including need vasoactive drugs was studied....
