Ligamentum teres hepatis as a graft for portal and/or superior mesenteric vein reconstruction: From bench to bedside.

Background: Pancreaticoduodenectomy combined with portal vein (PV) and/or superior mesenteric vein (SMV) resection in patients with pancreaticobiliary malignancy has become a common surgical procedure. There are various grafts currently used for PV and/or SMV reconstruction, but each of these grafts have certain limitations. Therefore, it is necessary to explore novel grafts that have an extensive resource pool, are low cost with good clinical application, and are without immune response rejection or additional damage to patients.

Diagnosis and surgical management strategy for pediatric small bowel obstruction: Experience from a single medical center.

Identifying Bowel strangulation and the approach and timing of surgical intervention for pediatric SBO are still uncertain. In this study, 75 consecutive pediatric patients with surgically confirmed SBO were retrospectively reviewed. The patients were divided into group 1 ( = 48) and group 2 ( = 27) according to the presence of reversible or irreversible bowel ischemia, which was analyzed based on the degree of ischemia at the time of operation.

Asymmetric figure-of-eight single-layer suture technique for intestinal anastomosis: A preliminary study.

Background: Anastomotic leakage is a life-threatening complication. Improvement of the anastomosis technique is needed, especially in patients with an inflamed edematous intestine. The aim of our study was to evaluate the safety and efficacy of an asymmetric figure-of-eight single-layer suture technique for intestinal anastomosis in pediatric patients.

An alternative asymmetric figure-of-eight single-layer suture technique for bowel anastomosis in an porcine model.

Anastomotic techniques are of vital importance in restoring gastrointestinal continuity after resection. An alternative asymmetric figure-of-eight single-layer suture anastomotic technique was introduced and its effects were evaluated in an porcine model. Twelve 15-cm grossly healthy small intestine segments from a porcine cadaver were harvested and randomly divided into asymmetric figure-of-eight single-layer suture (figure-of-eight suture) and single-layer interrupted suture technique (interrupted suture) groups ( = 6 in each group).

Severe Blunt Liver Injury Complicated by Delayed Massive Hemobilia in a Toddler: A Case Report and Literature Review.

Introduction: Unintentional injuries remain a leading cause of disability among children. Although most of the pediatric patients suffering blunt liver injury can be successfully treated with non-operative therapy, the diagnosis and management of delayed life-threatening hemobilia following severe blunt liver injury, especially in the pediatric population, remain a challenge for clinicians.

Case Presentation: A previously healthy 2-year-old girl suffered a severe blunt liver injury related to an electric bike, which was inadvertently activated by herself.

Case Presentation: A 14-year-old girl presented with right lateral and posterior hip pain and fever for 7 days before admission.

Pediatric Multiple High-Powered Magnetic Buckyballs Ingestion-Experience From Six Tertiary Medical Centers.

Multiple high-powered magnetic Buckyball ingestions may lead to a high risk of severe complications. Great concerns have been raised by public health workers, and it remains challenging for clinicians to solve this troublesome problem. We report a large case series of children with Buckyball ingestion from six tertiary medical centers.

The role of surgical management of BCG vaccine-induced regional suppurative lymphadenitis in children: a 7 years' experience from one medical center.

Background: The management strategy of Bacille Calmette-Guérin (BCG) vaccine-induced regional suppurative lymphadenitis in children is still controversial and more clinical studies are needed. We therefore present a surgical case series to explore the role of surgical management for this dilemma.

Methods: From January 2013 to June 2020, data from 65 patients diagnosed with BCG vaccine-induced regional suppurative lymphadenitis were retrospectively reviewed.

[Measurement of human body composition: in vivo techniques and related evaluation].

The in vivo techniques for studying human body composition have built up an important field and are continuing to be developed. This review provides an overview of the present status of this field and describes the in vivo techniques used in mearsuring human body composition such as anthropometry, metabolites method, densitometry, dilution method, total body potassium, neutron activation analysis, bioelectrical impedance analysis, dual energy X ray absorptiometry and imaging method. The review also introduces the principle, method and value of these techniques.

Effects of L-arginine on serum nitric oxide, nitric oxide synthase and mucosal Na+-K+-ATPase and nitric oxide synthase activity in segmental small-bowel autotransplantation model.

Aim: To explore a simple method to create intestinal autotransplantation in rats and growing pigs and to investigate the effect of L-arginine supplementation on serum nitric oxide (NO), nitric oxide synthase (NOS) and intestinal mucosal NOS and Na+-K+-ATPase activity during cold ischemia-reperfusion (IR) in growing pigs.

Methods: In adult Wistar rat models of small bowel autotransplantation, a fine tube was inserted into mesenteric artery via the abdominal aorta. The superior mesenteric artery and vein were occluded.

L-arginine administration ameliorates serum and pulmonary cytokine response after gut ischemia-reperfusion in immature rats.

Aim: Small intestinal ischemia-reperfusion (IR) has been demonstrated to result in both local mucosal injury and systemic injuries. The exact role of nitric oxide (NO) in intestinal IR is unclear. We propose that NO and some other cytokines change in the reperfusion period and these changes are associated with lung injury.
