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

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

The AirSeal TM : A new insufflation system for laparoscopic Surgery. Preliminary data concerning physiological changes.
Introduction:The physiopathologic consequences of pneumoperitoneum are well known. In the attempt to minimize CO2 peritonel uptake and the related physiological consequences, a new generation of insufflation systems and trocars are in development. This experimental animal study aims to assess the applicability and safety of a new insufflation and trocar system for laparoscopic surgery: the AirSeal… Continue Reading

Surgically Created Taste Aversions Develop in Rats Following Roux-en-Y Gastric Bypass
Background: Effective non-surgical treatment of morbid obesity continues to elude the medical community. Capturing positive effects of Roux-en-Y gastric bypass (RYGB) without surgery may be essential in achieving this goal. We have previously shown that patients experience taste changes and aversions following RYGB. A rat model for RYGB can help define these changes as physiological… Continue Reading

Decreased expression of hepatic signaling phosphoproteins after laparoscopic and hand-Assisted surgery
Background: Minimally-invasive surgery is associated with a decreased activation of both systemic and peritoneal immunity as compared to the open (O) technique. However, the hepatic response to laparoscopic (L) and hand-assisted (HA) surgery has not been defined well. We postulated that both laparoscopic and hand-assisted approaches are associated with a diminished expression of hepatic pro-inflammatory… Continue Reading

Evaluation of Influence of Pneumoperitoneum on the Abdominal Solid Organs By Microdialysis: Experimental Study
Background: Nowadays, laparoscopic surgery has feasibility of partial liver resection and pancreatectomy because of less invasion than a conventional open operation. It is known increased intra-abdominal pressure on the liver and on the pancreas induce reduction of micro- and macro-circulation and this cause severe damage on splanchnic organs. However there is not enough monitoring method… Continue Reading

Comparison between open and laparoscopic surgery for colorectal cancer
Aim of this study is to report the clinical results of 852 consecutive colorectal cancer (CRC) resections between April 2001 and December 2006.Laparoscopic bowel resection (LAC) with lymph node dissection (D2/D3) was applied for advanced CRC as well as LAC with D1 lymph node dissection for early CRC where endoscopic mucosal resection was not indicated.… Continue Reading

Surgical Treatment of Appendicitis with Peritonitis
Objective: This study aims to know which access is chosen in case of appendicitis with localised or diffused peritonitis and to evaluate the intra operative and postoperative complications.Technique: Prospective analysis including all patients admitted with appendicular peritonitis. Open appendectomy is undertaken through iliac or midline laparotomy. Laparoscopic appendectomy is undertaken through 3 or 4 trocars.Patients:… Continue Reading

Laparoscopic Vs Open Colon Resection for the Treatment of Perforated or Complicated Diverticular Disease ( Hinchey Stage I and II )
[Background]: Diverticular disease affects more than half the Western population over the age of 60. Diverticulosis of the right colon is rare among Western people, whereas reports from Asia conclude that the occurrence of diverticula of the right colon but not of the left colon, has been increasing in recent years. [Aim]: Elective laparoscopic surgery… Continue Reading

Initial results of omental pedicled shelf after rectal resection
Introduction: The incidence of bowel obstruction after rectal resection is approximately 6-10%. It may be an underestimate (detection bias). About half of them need laparotomy. We believe the dominant cause lies in pelvic incarceration of bowel loops. Greater omentum has been used for multiple indications in surgery however the data for its use in rectal… Continue Reading

Identification of factors affected by a learning curve for laparoscopic rectal resection
Objective: The aim of this study was to identify factors affected by surgeon’s experience of laparoscopic resection for rectal cancer.Methods: A total of 200 consecutive resections between June1995 and August 2007 were analyzed in an attempt to define a learning curve. These resections were divided into three groups, which were operated on by surgeons with… Continue Reading

Retrospective study comparing laparoscopic and open resection for transeverse colon cancer
BackgroundAlthough the large randomized trials are going about laparoscopic-assited colectomy(LAC) versus open colectomy(OC) for cancer, all of thease excluded patients with transverse colon cancer. Our study aimed to compare efficacy and safty of LAC and OC for treatment of transverse colon cancer in terms of morbidity and tumor recurrence and survivals.MethodsFrom February,1995,to March 2007, all… Continue Reading
