Laparoscopic surgery for solid pseudopapillary tumor of the pancreas.

Background And Objectives: Solid pseudopapillary tumors of the pancreas are rare and occur most frequently in young women. They have an uncertain pathogenesis and unclear clinical behavior. Our aim was to evaluate the clinical presentation of solid pseudopapillary tumors and assess the efficacy of treatment with minimally invasive surgery.

Thermal fixation of swine liver tissue after magnetic resonance-guided high-intensity focused ultrasound ablation.

The aim of this study was to investigate experimental conditions for efficient and controlled in vivo liver tissue ablation by magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) in a swine model, with the ultimate goal of improving clinical treatment outcome. Histological changes were examined both acutely (four animals) and 1 wk after treatment (five animals). Effects of acoustic power and multiple sonication cycles were investigated.

Laparoscopic versus open surgery in stage I-III adrenocortical carcinoma -- a retrospective comparison of 32 patients.

Laparoscopic surgery (LS) for resectable adrenocortical carcinoma (ACC) has been questioned due to uncertainty with regard to long-term oncological outcome. We analyzed the experience with LS compared to open surgery (OS) at Oslo University Hospital (OUH). Material and methods.

Laparoscopic resection of exocrine carcinoma in central and distal pancreas results in a high rate of radical resections and long postoperative survival.

Background: The role of laparoscopic resection in patients with pancreatic cancer remains to be clarified, because previous reports have not clearly defined oncologic outcomes. The objective of the present study was to investigate this question with the rate of R0 resection and long-term survival as endpoints.

Methods: This retrospective observational study included prospectively collected data from 40 patients operated laparoscopically with curative intent for exocrine pancreatic malignancies identified among 250 consecutive patients undergoing laparoscopic pancreatic operations since 1997.

Comparative evaluation of laparoscopic liver resection for posterosuperior and anterolateral segments.

Background: Totally laparoscopic liver resection of lesions located in the posterosuperior segments is reported to be technically challenging. This study aimed to define whether these technical difficulties affect the surgical outcome.

Methods: A total of 220 patients underwent laparoscopic liver resection during 244 procedures from August 1998 to December 2010.

Impact of body mass index on outcomes of laparoscopic adrenal surgery.

Objective: The aim of this article is to define the relationship between body mass index (BMI) and outcomes of laparoscopic adrenalectomy.

Method: A total of 172 patients were eligible for inclusion in the study. The patients were divided into 3 groups: group I, normal weight; group II, overweight; and group III, obesity.

Laparoscopic resection of colorectal liver metastases: surgical and long-term oncologic outcome.

Objective: To analyze the immediate and long-term outcome after laparoscopic resection of colorectal liver metastases and difference between observed and predicted [Fong's and Basingstoke Predictive Index (BPI) scores] survivals.

Background: : Laparoscopic liver resection has been reported safe and feasible and improves postoperative course. The oncologic outcomes after resection of colorectal metastases are poorly reported.

Should we use laparoscopic adrenalectomy for metastases? Scandinavian multicenter study.

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 performed during follow-up of the patients operated for malignant tumors.

Laparoscopic adrenalectomy: Norwegian single-center experience of 242 procedures.

Background: The last 15 years have been characterized by a rapid expansion of minimally invasive surgery as treatment for adrenal diseases. During these years, both indications and surgical techniques have shown improvements. This study analyzed an 11-year single-center experience with laparoscopic adrenalectomy.
