Morbidly Obese Patients Do Not Have Increased Incidence of Early Recurrence After Laparoscopic Ventral Hernia Repair
INTRODUCTION: Previous studies have raised concern that morbid obesity is associated with a markedly increased risk of recurrence after repair of ventral hernias. This study compared the incidence of early post-operative recurrence after laparoscopic ventral hernia repair in morbidly obese patients and non-morbidly obese patients.METHODS: Case notes were reviewed for consecutive patients who underwent laparoscopic… Continue Reading

Laparoscopic Suprapubic Hernia Repair in the Overweight Population
Background: Laparoscopic suprapubic hernia repair (LSHR) is technically challenging, requiring difficult, dissection in the superior pelvis. Obesity creates an added complexity to the repair itself, and to the complications and recurrences that may develop.Methods: We retrospectively reviewed 22 overweight and obese patients who underwent LSHR by one surgeon between the years of 2005 to 2007.… Continue Reading

Mechanisms of Ventral Hernia Recurrence Following Laparoscopic Repair
Objective: To determine mechanisms of ventral hernia recurrence following laparoscopic repair.Background: Laparoscopic ventral hernia repair techniques have demonstrated low recurrence rates in recent years. Mechanisms of recurrence following open repair are well-documented, but there is less data defining how laparoscopically-repaired hernias recur.Methods: We performed a retrospective analysis of 25 patients who had previously undergone at… Continue Reading

“Clinically Significant Reason for TAPPS over TEPPS?”
Introduction: Would the ability to diagnose unexpected secondary findings be a crucial factor to choose TAPPS over TEPPS? The primary surgeon of this abstract incidentally diagnosed a liver malignancy that prompted this question. Over the years, debate between the two approaches has been an on-going issue. Neither surgery has demonstrated definitive superiority over the other.… Continue Reading

Trans-gastric Ventral Abdominal Wall Placement of a Biologic Mesh
Introduction:We proposed a feasibility study to determine if biologic mesh may be safely placed in the abdomen in a transgastric fashion, as a precursor to attempting transgastric ventral hernia repair.Methods:Six swine underwent upper endoscopy after decontamination of the stomach with povidone-iodine (Betadine). Under endoscopic guidance the gastric wall was perforated. A plastic overtube was introduced… Continue Reading

A Minimally Invasive Approach to a ‘ Seatbelt Hernia\’
A MINIMALLY INVASIVE APPROACH TO A ‘ SEATBELT HERNIA’.Elyssa Feinberg MD, Aksim Rivera MD, Suttatip Vechvitvarakul MD , Ajay K Chopra MD.Jacobi Medical Center, Albert Einstein College of Medicine, Bronx NYIntroduction: Traumatic abdominal wall hernias are often the result of improperly worn lap and shoulder seat belts. Most cases of traumatic lumbar/flank hernias described have… Continue Reading

Obesity Contributes to Recurrence after Laparoscopic Incisional Hernia Repair
Objective: Obesity is a known risk factor for the development of incisional hernias. Despite the widespread use of prosthetic mesh, recurrence rates for open repair in obesity remain high. The magnitude of mechanical force exerted on the abdominal wall in obese individuals may contribute to a higher than expected recurrent incisional hernia rate. Laparoscopic ventral… Continue Reading

Open Hernia Repair neccessity in Basic Surgical Training
Introduction With the increasing uptake of laparoscopic hernia repairs, there could be concern that the availability of this basic open training procedure will be less for the current cohort of trainees as consultants and experienced registrars are doing more hernia repairs laparoscopically. This study aimed to determine whether there was a reduction in trainee exposure… Continue Reading

Chronic Aspiration Shifts the Immunue Response from Th-1 to Th-2 in a Murine Model of Asthma
Chronic aspiration associated with gastroesophageal reflux disease (GERD) is thought to play a substantial role in the development of asthma, the incidence of which is dramatically increasing in industrially developed countries. The majority of data examining the association between aspiration and asthma has been obtained from epidemiological studies, which show that between 50 and 90%… Continue Reading

Small skin incision dose not have any beneficial effect on cytokine expression in malnourished rats after laparotomy
Background and Objectives: Small skin incision, like laparoscopic surgery had been reported that it was better on pain, inflammatory responses and duration of hospital stay compared to conventional open laparotomy, however, we have a little evidence for beneficial effect on laparoscopic surgery in malnourished patients. The aims of this study were to asses whether small… Continue Reading

Ex-vivo Comparison of the Efficiencies of LOTUS® and Ethicon® Ultrasonic Instruments
Aims: To compare energy utilisation and dissecting efficiencies of Ethicon® and LOTUS® ultrasonic surgical instruments.Methods: 1. Calorimetry experiments were performed to compare thermal energy produced by ultrasonic surgical devices adopting longitudinal (Ethicon Harmonic Scalpel®; EHS) and torsional (Laparoscopic Operation by Torsional UltraSound®; LOTUS) vibration modes, using differently shaped waveguide tips.2. An ex-vivo bench model was… Continue Reading

CO2-Pneumoperitoneum Induces Renal Apoptosis in a Rat Model
Background: Kidneys harvested by laparoscopic donor nephrectomy regain normal function slightly later than laparotomy-harvested organs. Several factors affect the organs after laparoscopic recruitment, which could explain the relatively prolonged period of recovery. We investigate the role of CO2-induced pneumoperitoneum (PNP) on organ dysfunction as expressed by cell apoptosis.Methods: CO2-PNP was established in 24 anesthetized Wistar… Continue Reading

Polypropylene mesh (PPM) or Light weight mesh (LWM) in inguinal hernia surgery (TEP)- results of a prospective randomized controlled study
Objectives of study-Mesh application in endoscopic hernia surgery is universal. Textile, weight and pore size of mesh continue to be debated. LWMs with larger pores seem to address the concerns of host response. Aim of this study was to evaluate the advantages if any of LWMs over PPMs in totally extraperitoneal (TEP) repair of inguinal… Continue Reading

Incisions Do Not Linearly Sum
Introduction: Critics of minimally invasive methods sometimes argue that the sum of lengths of all trocar sites are similarly morbid to a “conventional” incision of equal length. This argument assumes correctly that pain and scarring are proportional to total tension normal to a linear incision. But the argument also assumes that total tension sums linearly… Continue Reading

Real-Time Dynamics of Nitric Oxide within the Esophageal Wall
Objective: Current evidence suggests that the neurotransmitter Nitric Oxide (NO) plays a crucial role in the genesis of aboral propagative of esophageal peristalses during swallowing. However, direct evidence in this regard is lacking at present. The objective of this study was to measure changes in the level of NO within the intermuscular interstices of esophagus… Continue Reading
