A modification with threading cannula needle-assisted 4-point suspension fixation for retroperitoneal laparoscopic pyeloplasty in children with ureteropelvic junction obstruction: a cohort study in single center.

Int Urol Nephrol 2018 Dec 5. Epub 2018 Dec 5.

Department of Urology, The Third Affiliated Hospital of Sun Yat-sen University, Tianhe Road 600, Guangzhou, 510630, Guangdong, China.

Purpose: To evaluate the effect and safety of modifying a threading cannula needle-assisted suspension fixation in retroperitoneal laparoscopic dismembered pyeloplasty (LDP) for children with congenital ureteropelvic junction obstruction (UPJO).

Methods: Between December 2012 and December 2017, 45 children (< 14 years of age) with congenital UPJO were divided into two groups. In Group A, children underwent conventional "no-suspension fixation" LDP; and in Group B, "4-point suspension fixation" LDP was performed to lower difficulties and shorten operative time. Read More

Functional Polymorphisms in Gene and Neuroblastoma Risk in Chinese Children.

J Cancer 2018 31;9(23):4521-4526. Epub 2018 Oct 31.

Department of Pathology, Anhui Provincial Children's Hospital, Hefei 230051, Anhui, China.

Neuroblastoma is a lethal tumor of the sympathetic nervous system. 8-Hydroxydeoxyguanine (8-OH-dG) formation is a common seen type of oxidative DNA damage, which could be repaired by human oxoguanine glycosylase 1 (hOGG1). To explore the contributing role of gene single nucleotide polymorphisms (SNPs) in neuroblastoma risk, we performed a case-control study by genotyping three SNPs (rs1052133 G>C, rs159153 T>C, rs293795 A>G) in gene.

ECMO Flow as a Sign of Intraabdominal Hemorrhage After Prolonged CPR.

ASAIO J 2018 Nov 28. Epub 2018 Nov 28.

From the Division of Cardiovascular and Thoracic Surgery, Department of Surgery, Duke University Medical Center, Durham, North Carolina.

Although life-saving, cardiopulmonary resuscitation (CPR) has been associated with traumatic injuries in adult patients surviving cardiac arrest. In addition to rib and sternal fractures, intraabdominal injuries have also been shown to occur, particularly after prolonged external cardiac massage. Early detection of these injuries remains difficult and is often masked by concomitant hemodynamic instability and the higher likelihood of other injuries such as retroperitoneal hemorrhage.

Incisions and reconstruction approaches for large sarcomas.

Transl Gastroenterol Hepatol 2018 31;3:86. Epub 2018 Oct 31.

Division of Plastic Surgery, Department of Surgery, Indiana University School of Medicine, Indianapolis, IN, USA.

Large intraabdominal, retroperitoneal, and abdominal wall sarcomas provide unique challenges in treatment due to their variable histology, potential considerable size at the time of diagnosis, and the ability to invade into critical structures. Historically, some of these tumors were considered inoperable if surgical access was limited or the consequential defect was unable to be closed primarily as reconstructive options were limited. Over time, there has been a greater understanding of the abdominal wall anatomy and mechanics, which has resulted in the development of new techniques to allow for sound oncologic resections and viable, durable options for abdominal wall reconstruction.

[Intra-abdominal infections. Update and recommendations].

Medicina (B Aires) 2018 ;78(6):417-426

Hospital Prof. Alejandro Posadas, El Palomar, Buenos Aires, Argentina.

Intra-abdominal infections represent a group of intra and retroperitoneal processes, ranging from localized infections to complicated ones, sepsis and septic shock, associated with a significant mortality rate. They are the third most commonly identified cause of sepsis and the second cause of death in the intensive care unit. Although antimicrobial therapy must be started as soon as possible, especially in critically ill patients, the source control procedure is highly relevant. Read More

Coexistence of duodenum derived aggressive fibromatosis and paraduodenal hydatid cyst: A case report and review of literature.

World J Gastrointest Surg 2018 Nov;10(8):90-94

Department of Pathology, Inonu University Faculty of Medicine, Malatya 244280, Turkey.

Intra-abdominal aggressive fibromatosis is a locally aggressive tumor mostly originating from the mesentery or retroperitoneal space, infiltrating adjacent tissues, and very rarely metastasizing to distant organs. There are only two case reports in the English language literature where intra-abdominal aggressive fibromatosis originated from the intestinal wall. In this study, we aimed to report a case of aggressive fibromatosis originating from the muscularis propria layer of the duodenum and invading pancreas. Read More

IgG4-related kidney disease and retroperitoneal fibrosis: An update.

Mod Rheumatol 2018 Nov 30:1-24. Epub 2018 Nov 30.

c Division of Nephrology and Rheumatology, Department of Internal Medicine, Faculty of Medicine , Fukuoka University , Fukuoka , Japan.

The most representative kidney lesion of IgG4-related disease (IgG4-RD) is plasma cell-rich tubulointerstitial nephritis (TIN) with distinctive imaging findings including multiple low-density lesions on contrast-enhanced computed tomography. In addition, membranous glomerulonephritis is a representative glomerular lesion of this disease. Recent advances have clarified that inflammation with IgG4-positive plasma cell infiltrates is not restricted to the renal parenchyma, but can be seen in outside the renal capsule, around medium-sized arteries such as lobar arteries, around nerves, and in the renal pelvis and periureter.

Retroperitoneal diseases are frequently a great clinical challenge because of their nonspecific presentation. Diseases may be asymptomatic with indolent biological behavior, and often show a large mass at initial imaging evaluation. Magnetic resonance (MR) imaging is a powerful diagnostic technique for assessment of detailed disease location and for characterization of tissue components and vascularization of lesions, with many advantages compared with computed tomography and ultrasonography.

Minimally invasive thoracolumbar corpectomy and stabilization for unstable burst fractures using intraoperative computed tomography and computer assisted spinal navigation.

Warren Alpert Medical School of Brown University, Department of Neurosurgery, Providence, Rhode Island, 02903, USA; Norman Prince Neurosciences Institute, Rhode Island Hospital, Providence, Rhode Island, 02903, USA. Electronic address:

Background: Minimally invasive (MIS) 'mini-open' lateral retropleural or retroperitoneal approach corpectomy is a well described procedure for treating unstable thoracolumbar burst fractures. Most surgeons incorporate fluoroscopy for localization and determination of hardware placement accuracy, but the utility of computer assisted image guided spinal navigation has not been well described. In this study, we report a series of mini-open lateral approach thoracolumbar corpectomy cases using either fluoroscopy or intraoperative computed tomography (iCT) with computer assisted navigation and discuss the technical nuances and advantages of using iCT with navigation versus fluoroscopy.
