INTRODUCTION: Surgical site infection (SSI) is a frequent complication of abdominal surgery causing increased morbidity. Triclosan-coated sutures are recommended to reduce SSI. The aim of this systematic review and meta-analysis was to evaluate the evidence from randomized controlled trials (RCT) comparing the rate of SSI in abdominal surgery when using triclosan-coated or uncoated sutures for fascial closure. METHODS: A systematic literature search was conducted using Medline, EMBASE, the Cochrane library, CINAHL, Scopus and Web of Science including publications until August 2017...

Browning et al describe procedures for prevention of incontinence in women undergoing obstetric fistula (OF) repair or treatment of women who have residual incontinence after successful fistula closure. Their premise is that scarring and decreased elasticity of the anterior vagina results in opposing forces on the urethra thereby causing incontinence-the so called Integral Theory. By employing a rotational skin flap from the adjacent thigh, the vaginal wall elasticity is restored. Their technique does not include the fascial portion of the flap which is widely considered to be important for preservation of the blood supply...

In the surgical management of large incisional hernias, the main target is the closure of the abdominal wall defect on the midline without a dangerous increase in the intraabdominal pressure. In this setting, new intraperitoneal prosthesis and components separation techniques were proposed to solve this problem. Both solutions present some critical issues. A new surgical approach with a free lateral double layer prosthesis totally in polypropylene both sides (FLaPp(®)) is proposed to overcome this problem...

BACKGROUND: Bochdalek hernias are one of the most common types of diaphragmatic hernia, with most cases diagnosed during the neonatal period. In contrast, diagnosis of a Bochdalek hernia in an adult is rare and is typically observed on the left side of the diaphragm. Even more rare is the diagnosis of a right-sided Bochdalek hernia in an adult, where there is concurrent visceral malformation in most cases. CASE PRESENTATION: We describe a case of an 89-year-old female who presented with abdominal pain...

Wood formation is a complex developmental process under multi-level transcriptional control executed by a large set of transcription factors. However, only limited members have been characterized to be key regulators of lignin biosynthesis in poplar. Here we report the conserved and unique functions of PtoMYB170, a transcription factor identified from Populus tomentosa (Chinese white poplar), in lignin deposition and drought tolerance in comparison with its duplicate paralog PtoMYB216. PtoMYB170 is preferentially expressed in young leaves and xylem tissues...

BACKGROUND: Echocardiographic longitudinal markers of right ventricular (RV) systolic function are commonly depressed after coronary artery bypass graft surgery (CABG) despite an uncomplicated course and good clinical recovery. The exact timing and cause of these changes is unknown. The aim of this observational study was to monitor echocardiographic markers of RV systolic function intraoperatively during CABG. We used angle-independent speckle tracking to measure the primary endpoints of tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular systolic velocity (S') before and after pericardiotomy...

In this work, CFD simulations of an air-water bubbling column were performed and validated with experimental data. The superficial gas velocities used for the experiments were 0.019 and 0.038 m/s and were considered as an homogeneous regime. The former involves simpler physics when compared to a heterogeneous regime where the superficial velocities are higher. In order to simulate the system, a population balance model (PBM) was solved numerically using a discrete method and a closure kernels involving the Luo coalescence model as well as two different breakup models: Luo's and Lehr's...

Plant cell separation and expansion require pectin degradation by endogenous pectinases such as polygalacturonases, few of which have been functionally characterized. Stomata are a unique system to study both processes because stomatal maturation involves limited separation between sister guard cells and stomatal responses require reversible guard cell elongation and contraction. However, the molecular mechanisms for how stomatal pores form and how guard cell walls facilitate dynamic stomatal responses remain poorly understood...

Background: During laparotomy, surgeons may experience difficult surgical conditions if the patient's abdominal wall or diaphragm is tense. Deep neuromuscular block (NMB), defined as a post-tetanic-count (PTC) between 0-1, paralyses the abdominal wall muscles and the diaphragm. We hypothesized that deep NMB (PTC 0-1) would improve subjective ratings of surgical conditions during upper laparotomy as compared with standard NMB. Methods: This was a double blinded, randomized study...

Despite advances in trauma care, a subset of patients surviving damage control cannot achieve fascial closure and require split-thickness skin grafting (STSG) of their open abdomen. Controversy exists as to whether reconstruction of the gastrointestine (GI) should be staged or performed at the time of abdominal wall reconstruction (AWR). Many surgeons do not believe that operations through the STSG can be completed safely or without loss of graft. This series reviews the outcomes of operations for GI reconstruction performed through the elevated healed STSG...

INTRODUCTION: Contaminated abdominal fascial defects, such as those seen in enterocutaneous fistula, or wound dehiscence with mesh exposure, are a significant source of morbidity and present unique reconstructive challenges. We present our technique of using the fascia lata, augmented with an interpositional omental flap, for complete autologous reconstruction of contaminated fascial defects, and the postoperative results of 3 cases. METHODS: Three patients with contaminated abdominal defects underwent wound debridement/fistula resection and immediate reconstruction with fascia lata and omentum flap...

BACKGROUND AND OBJECTIVES: Robot-assisted hernia repair, combined with endoscopic component separation, has reduced recurrence and complication rates and allowed immediate intervention in obese patients. We sought to study surgical outcomes in this high-risk group of patients in a community hospital. METHODS: We conducted a retrospective chart review of ventral, incisional, and umbilical hernia repairs performed at a small community hospital by a single surgeon from March 2014 through November 2016, with statistical analysis of the surgical outcomes...

M Abu-Serriah, S Loughran
Circumferential defects of the hypopharynx are a reconstructive challenge. Various local, regional and free flaps have been described with each having advantages and disadvantages in terms of functional outcomes. The fasciocutaneous radial forearm free flap (RFFF) is one of the most common free flaps used for reconstructing circumferential hypopharyngeal defects. The skin paddle is pliable and reasonably matches the native hypopharyngeal wall. It is easy to raise, has predictable vascular anatomy and a long pedicle...

PURPOSE: Open anterior release of the external oblique fascia to enable midline closure of large abdominal wall defects is associated with relevant morbidity due to extensive subcutaneous dissection. Using endoscopic techniques, wound complications can be minimized. However, identification of the correct entry point (e.g. for balloon trocar insertion) can be challenging especially in adipose patients. We therefore present a technical modification facilitating the entire procedure. METHODS: A novel technique for endoscopic anterior component separation using a trocar system allowing blunt and sharp dissection under direct vision is described...

PURPOSE: Research has established that a ≥4:1 suture to wound (S:W) length ratio decreases incisional hernias. We evaluated our ability to obtain a 4:1 S:W length ratio in a surgery residency program. METHODS: Consecutive abdominal wall closures from 12/1/2013 through 4/9/2015 were reviewed. The length of the incisions and amount of suture used were measured. Patient demographics and operative variables were documented and compared related to inability to obtain a 4:1 ratio...

Lipid membranes serve as effective barriers allowing cells to maintain internal composition differing from that of extracellular medium. Membrane permeation, both natural and artificial, can take place via appearance of transversal pores. The rearrangements of lipids leading to pore formation in the intact membrane are not yet understood in details. We applied continuum elasticity theory to obtain continuous trajectory of pore formation and closure, and analyzed molecular dynamics trajectories of pre-formed pore reseal...

Spontaneous neonatal gastric perforation is rare. We report the case of a newborn without any abnormality identified at delivery and whose mother had problem-free pregnancy. On the third day of life, he had a sudden onset of severe abdominal distension followed by bilious vomiting. Abdominal X-rays without treatment showed massive pneumoperitoneum and laparotomy showed a perforation at the level of the anterior gastric wall closed in a single layer closure. Postoperative course was uneventful. Spontaneous neonatal gastric perforation usually has a favorable outcome...

BACKGROUND: Isthmocele is a characteristic semi-diverticular anomaly of the anterior isthmic wall of the uterus, located at the site of a previous cesarean delivery scar. The etiopathogenesis of isthmocele is still poorly understood, and several hypotheses have been proposed. Possible factors that could play a role in niche development include a very low incision through cervical tissue, an inadequate suturing technique during the closure of the uterine scar surgical interventions that increase adhesion formation or patient-related factors that impair wound healing, or increase inflammation or adhesion formation...

BACKGROUND: In the patient of the cloacal exstrophy, cloaca with local abdominal wall is disrupted and exposed inner surface of the bladder needs early closure. Pelvic osteotomies are required for severe cases whose bladder cannot be closed by the suture of soft tissue only. We developed a technique involving the gradual positioning of bone fragments using a light, Ilizarov external fixator. The usefulness of the technique was assessed. METHODS: We enrolled 3 patients with cloacal exstrophy and 1 with bladder exstrophy as a gradual transfer group and 6 patients who were treated by other osteotomies as a control group...
