Background: The follow-up of drained infected pancreatic necrosis (IPN) is usually done with data on the patient's clinical evolution and information obtained from serial helical computed tomographic scans. Management often requires necrosectomies and periodic debridements.
Hypothesis: Translumbar retroperitoneal endoscopy is effective in the management of drained IPN.
Design: A prospective observational study.
Setting: University tertiary care hospital.
Patients: A series of 11 consecutive patients with drained IPN undergoing postoperative follow-up with translumbar retroperitoneal endoscopy.
Interventions: Initially, the IPN was drained via the posterior extraperitoneal translumbar approach; then, a superficial necrosectomy was performed during the same surgical intervention by flushing and endoscopic aspiration; and, finally, a lavage and drainage system was fitted. In the immediate postoperative period, for management of the IPN, we removed the drainage tube and inserted a flexible endoscope as far as the pancreatic area to eliminate the infected necrotic material by flushing and aspiration.
Main Outcome Measures: In these patients, we studied control of the infection of the pancreatic area, quantification variables of the necrosectomy, technique-related morbidity and mortality, and the need for subsequent operations.
Results: The 11 patients studied showed good results regarding the control and complete elimination of the infected necrosis. There was no technique-related morbidity or mortality or need for subsequent operations.
Conclusion: Translumbar retroperitoneal endoscopy allows exploration of the retroperitoneal space under direct visual guidance, facilitates lavage and aspiration, avoids subsequent surgical operations for debridement, decreases the need for repeated computed tomographic scans to evaluate the evolution of the IPN, and has no added morbidity or mortality.

Purpose: To examine the reported adverse events associated with inferior vena cava (IVC) catheterization and investigate the reasons for discrepancies between reports.
Materials And Methods: Cochrane Library trials register, PubMed, Embase, and Scopus databases were systematically searched for studies that included any terms of IVC and phrases related to catheters or central access. Of the 5,075 searched studies, 137 were included in the full-text evaluation.

Aortic injury is a frequently encountered condition that can present as a life-threatening emergency. When this injury occurs in the retroperitoneal portion of the aorta, it can be difficult to diagnose and treat because of the location. Although surgical repair remains the mainstay of treatment, surgery might not be an option for some patients.

Background: Laparoscopic donor nephrectomy (LDN) converted a retroperitoneal (RP) procedure into a transperitoneal (TP) operation with reports of bowel and solid organ injuries leading to mortality in occasional cases. Laparoscopic RP donor nephrectomy can reduce these risks but never became popular because of the muscle cutting approach. Lumbotomy incision can be used to approach retroperitoneum by incising fascial planes, eliminating disadvantages of the RP approach.

Large-caliber access to the arterial system is more frequently required in the age of thoracic endovascular aneurysm repair, endovascular aneurysm repair, and transaortic valve implantation. Frequently either anatomical or vessel size constraints preclude use of common access points such as the common femoral, radial, and brachial arteries. Alternative approaches include percutaneous access at alternate sites (subclavian, axillary, and carotid), open surgical access to the heart (left ventricular apex), open surgical access to large-caliber vessels (ascending aorta, subclavian, and axillary arteries, retroperitoneal access to the iliac artery or distal aorta), and novel percutaneous approaches (transvenous).

Introduction And Objective: Surgery for necrotizing pancreatitis is associated with a high rate of morbidity and mortality. We present a series of 26 patients who underwent video-assisted translumbar retroperitoneal necrosectomy and analyse their outcomes.
Methods: Records of 26 patients who underwent video-assisted translumbar retroperitoneal necrosectomy and closed drainage for infected pancreatitic necrosis between January 2008 and March 2012 were reviewed, retrospectively.
