Thoracic and lumbar cortical bone trajectory pedicle screws have been described in adult spine surgery. They have likewise been described in pediatric CT-based morphometric studies; however, clinical experience in the pediatric age group is limited. The authors here describe the use of cortical bone trajectory pedicle screws in posterior instrumented spinal fusions from the upper thoracic to the lumbar spine in 12 children. This dedicated study represents the initial use of cortical screws in pediatric spine surgery...

This study evaluated the surgical technique and outcomes of cup revision involving retention of a fixed but malpositioned acetabular component in patients with poor general conditions.Between 2007 and 2013, we performed cup revision on 12 hips while retaining a fixed (either cemented or uncemented) but malpositioned acetabular component. Indications for this technique were: malpositioned but fixed acetabular shell; sufficient space for the insertion of the prosthesis; and patients with poor general conditions...

The transforaminal lumbar interbody fusion (TLIF) is used for the treatment of back and leg pain secondary to spinal stenosis, degenerative disc disease, and spondylolisthesis. Minimally invasive surgery (MIS) is associated with less estimated blood loss (EBL), decreased length of stay, lower infection rates, and similar outcomes compared to the traditional TLIF. Fluoroscopy time has been reported with MIS-TLIF, but there are limited data on specific radiation dosages. We performed a retrospective analysis of a prospectively acquired cohort of patients undergoing MIS-TLIF...

We studied the efficacy of prophylactic internal iliac artery balloon catheterization for managing severe hemorrhage caused by pernicious placenta previa.This prospective observational study was conducted in Tongji Hospital, Wuhan, China. One hundred sixty-three women past 32-week's gestation with placenta previa-accreta were recruited and managed. Women in the balloon group accepted prophylactic internal iliac artery balloon catheterization before scheduled caesarean delivery and controls had a conventional caesarean delivery...

BACKGROUND: A debate is still surrounding the use of laparoscopic surgery for advanced gastric cancer (AGC) related to doubts about the requirements to satisfy oncologic criteria. The aim of this study is to analyze the oncological results, the intraoperative complications, and the short- and medium-term morbidity and mortality in patients with AGC who underwent subtotal laparoscopic gastrectomy (SLG) or total laparoscopic gastrectomy (TLG) with extended lymphadenectomy. MATERIALS AND METHODS: We reviewed medical records of patients who underwent radical gastrectomy for AGC started laparoscopically with the intent of curative surgery, between July 2007 and October 2015...

BACKGROUND: Data on the safety and feasibility of laparoscopic versus open resection for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm are limited. Therefore, the aim of this meta-analysis was to compared laparoscopic and open resection for gastric GISTs larger than 5 cm. METHODS: We perform a literature search on PubMed, the Cochrane Library, and Embase. Review Manage version 5.1 (RevMan 5.1) was used for data analysis. The GRADE profiler software (version 3...

BACKGROUND The purpose of this study was to evaluate the effect and outcome of intraoperative fluid restriction in living liver donor hepatectomy, regarding changes in intraoperative CVP levels, blood loss, and postoperative renal function. MATERIAL AND METHODS The charts of 167 patients were reviewed and analyzed retrospectively. Intraoperative central venous pressure levels, blood loss, fluids infused, and urine output per hour, before and after the liver allograft procurement, were calculated. Perioperative renal functions were also analyzed...

BACKGROUND: Our objective was to quantify blood loss and transfusion requirements for high-dose and low-dose tranexamic acid (TXA) dosing regimens in pediatric patients undergoing spinal fusion for correction of idiopathic scoliosis. Previous investigators have established the efficacy of TXA in pediatric scoliosis surgery; however, the dosing regimens vary widely and the optimal dose has not been established. METHODS: We retrospectively analyzed electronic medical records for 116 patients who underwent spinal fusion surgery for idiopathic scoliosis by a single surgeon and were treated with TXA...

BACKGROUND: Hospitals review allogeneic red blood cell (RBC) transfusions for appropriateness. Audit criteria have been published that apply to 5 common procedures. We expanded on this work to study the management decision of selecting which cases involving transfusion of at least 1 RBC unit to audit (review) among all surgical procedures, including those previously studied. METHODS: This retrospective, observational study included 400,000 cases among 1891 different procedures over an 11-year period...

INTRODUCTION: Intraabdominal visceral obesity may increase technical challenges during laparoscopic rectal resection and hypothetically therefore increase the risk of perioperative complications. The aim of this study was to analyze intraabdominal obesity by means of perirenal fat against risk of adverse outcomes in patients undergoing laparoscopic rectal cancer surgery. METHODS: This study was a single-institution retrospective analysis of consecutive patients undergoing laparoscopic total mesorectal surgery for rectal cancer between January 2009 and January 2013...

Background: This retrospective analysis of patients who underwent adrenalectomy for pheochromocytoma aimed to determine preoperative risk factors for intraoperative massive blood loss. Preoperative identification of patients at high-risk of massive blood loss may be helpful in anesthesia management and preoperative preparation.

BACKGROUND: Conventional open and conventional laparoscopic splenectomy and azygoportal disconnection (CLSD) result in poor quality of life because of damage to the vagal nerve. We have developed vagus nerve-preserving laparoscopic splenectomy and azygoportal disconnection (VLSD).

BACKGROUND: Nissen fundoplication is considered an advanced minimally invasive procedure whether performed laparoscopically or robotically. In laparoscopic surgery, it is evident that assistant skill level impacts operative times. However, the robotic platform allows improved surgeon autonomy. We aimed to determine the impact of assistant training level on operative times in robotic Nissen fundoplication (RNF) and laparoscopic Nissen fundoplication (LNF). METHODS: A prospectively maintained Nissen database (2011-2016) from a single academic institution was utilized to collect patient characteristics, operative times, length of stay, intraoperative complications, postoperative complications, readmission rate, and assistant training level...

BACKGROUND: The objective of this study was to compare perioperative and early oncological outcomes of a matched cohort of patients who underwent retroperitoneal robot-assisted partial nephrectomy (RP-RAPN) and open partial nephrectomy (OPN) for clinically localized renal tumors. PATIENTS AND METHODS: We performed a retrospective analysis of patients who underwent RP-RAPN and OPN treated at 2 referral centers from January 2011 to December 2015. We focused on the following postoperative outcomes: warm ischemia time (WIT), operative time, blood loss, intra- and postoperative complications, estimated glomerular filtration rate (eGFR), hospital stay, and positive surgical margins...

We examined the effectiveness of tranexamic acid in preventing intraoperative blood loss during major cardiac surgery. Out of initial 81 patients undergoing major cardiac surgery (both coronary artery bypass and valve repair procedures) at our teaching hospital, sixty-seven patients were selected for this study. We compared estimated blood loss, decrease in percent hemoglobin and hematocrit following surgery between two groups of patients (none of them received any blood product during surgery), one group receiving no tranexamic acid (n=17) and another group receiving tranexamic acid (n=25)...

INTRODUCTION: Parastomal hernia is a common and vexing problem after ileal conduit urinary diversion that can cause pain, bowel symptoms, and problems with the stoma appliance, resulting in leakage, odor, and impairment of quality of life. Historically, these hernias have been managed open surgically, which requires considerable dissection of the abdominal wall for mesh placement, and may also require relocating the stoma to the contralateral side. Further, open parastomal hernia repair can be a morbid procedure with recurrence rates of approximately 30%...
