Emergency laparotomy at St Olav's Hospital, Trondheim.

Background: Emergency laparotomies are associated with higher mortality and longer hospital stays than elective laparotomies. The purpose of this study was to survey patient characteristics, hospital care pathways, and mortality for patients undergoing emergency laparotomy at St Olav's Hospital, Trondheim.

Material And Methods: This is a retrospective cohort study of all patients over 18 years of age who underwent emergency laparotomy at St Olav's Hospital, Trondheim, between 1 January 2015 and 1 April 2020.

Rates of caesarean section and total volume of surgery in Sierra Leone: a retrospective survey.

Background: Surgical services are essential components of health-care systems. Monitoring of surgical activity is important, but resource demanding. Simpler tools to estimate surgical volume, particularly in low-income countries, are needed.

Met and unmet needs for surgery in Sierra Leone: A comprehensive, retrospective, countrywide survey from all health care facilities performing operations in 2012.

Background: Understanding a country's baseline operative actors and capacity is critical to improving the quality of services and outcomes. The aim of this study was to describe all operative providers and national operative production, to evaluate district and nationwide population rates for operations, and to estimate unmet operative need in Sierra Leone.

Methods: A nationwide, exhaustive, retrospective, facility-based study of operative actors and surgical procedures was performed in Sierra Leone.

Motion tracking in the liver: validation of a method based on 4D ultrasound using a nonrigid registration technique.

Purpose: Treatments like radiotherapy and focused ultrasound in the abdomen require accurate motion tracking, in order to optimize dosage delivery to the target and minimize damage to critical structures and healthy tissues around the target. 4D ultrasound is a promising modality for motion tracking during such treatments. In this study, the authors evaluate the accuracy of motion tracking in the liver based on deformable registration of 4D ultrasound images.

A retrospective study evaluating the use of Permacol™ surgical implant in incisional and ventral hernia repair.

Background: The outcome of incisional and ventral hernia repair depends on surgical technique, patient, and material. Permacol™ surgical implant (crosslinked porcine collagen) has been used for over a decade; however, there are few data on outcomes. This study is the largest retrospective multinational study to date to evaluate outcomes with Permacol™ surgical implant in the repair of incisional and ventral hernias.

Degree of adhesions after repair of incisional hernia.

Background And Objectives: Laparoscopic treatment of incisional hernias reduces surgical traumas and postoperative pain. It requires intraperitoneal placement of a foreign body that might cause adhesions, leading to postoperative complications. The aim of this study was to improve reliability of ultrasound in quantitatively estimating adhesions to exploit the other advantages of ultrasound, such as availability and versatility.

Laparoscopic ultrasound: a survey of its current and future use, requirements, and integration with navigation technology.

Background: Laparoscopic ultrasound (LUS) increases surgical safety by allowing the surgeon to see beyond the organ surface, by visualizing vascular structures and by improving surgical precision of tumor resection. A questionnaire-based survey was used to investigate the current use and future expectations of LUS technology.

Methods: A questionnaire consisting of 26 questions was distributed manually at four different conferences (60% at the European Association for Endoscopic Surgery (EAES) conference, Stockholm 2008).

[3-D navigation in laparoscopic surgery].

Background: The main drawback with the laparoscopic approach is that the surgeon lacks the possibility to palpate vessels, tumours and organs during surgery. Furthermore, the laparoscope only provides a surface view of organs. There is a need for more advanced visualization that enhances the view to include information below the surface of the organs when the procedure is planned and for control and guidance during treatment.
