BACKGROUND: In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS: In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes...

INTRODUCTION: Postoperative shoulder pain is a condition associated with laparoscopic surgery and presumably attributed to residual carbon dioxide (CO2) in the abdomen. The intent of the current prospective, observational study was to assess the efficacy of abdominal compression in mitigating this painful complication. METHODS: We recruited 30 patients who were treated with laparoscopic surgery for the management of gynecologic disease. All study participants underwent abdominal compression to evacuate the CO2 associated with their pneumoperitoneum...

Capsular contracture is the most common complication of breast augmentation. Oxidized regenerated cellulose can be used as a matrix for drug transport. Colchicine is an antimitotic drug that interferes with various steps of wound healing. The aim of this study was to evaluate the effects of oxidized regenerated cellulose alone or in combination with colchicine on capsular contracture. Twenty-one adult female Wistar-Albino rats were divided into 3 groups. In group 1 silicone blocks only, in group 2 oxidized regenerated cellulose-wrapped silicone blocks, and in group 3 colchicine-impregnated oxidized regenerated cellulose-wrapped silicone blocks were inserted in the dorsal region...

INTRODUCTION: Peritoneal insufflation with warm-humidified (WH) CO2 gas during minimally invasive surgical procedures is purported to prevent hypothermia and peritoneal desiccation and is associated with decreased postoperative IL-6 levels. This randomized study's purpose was to determine the clinical impact of WH versus cold-dry (CD) CO2 in minimally invasive colon resection (MICR), and to assess perioperative plasma levels of IL-6, TIMP-1, sVEGF-R1, and HSP-70 after MICR. METHODS: Operative and short-term clinical data plus perioperative blood samples were collected on MICR patients randomized to receive either WH (36...

INTRODUCTION: New biological materials are needed for specific applications in reconstructive bowel surgery and for the prevention of adhesion formation. Amniotic membranes (AMs) are assumed to have a number of unique characteristics that enhance the ingrowth of the surrounding tissue. The aim of the present study was to provide proof of these qualities in a xenograft model. MATERIALS AND METHODS: A multilayer human AM (HAM) was applied to repair defined colon wall defects in Sprague-Dawley rats (n = 18)...

A clear visualization of the operative field is of critical importance in endoscopic surgery. During surgery the endoscope lens can get fouled by body fluids (eg, blood), ground substance, rinsing fluid, bone dust, or smoke plumes, resulting in visual impairment. As a result, surgeons spend part of the procedure on intermittent cleaning of the endoscope lens. Current cleaning methods that rely on manual wiping or a lens irrigation system are still far from ideal, leading to longer procedure times, dirtying of the surgical site, and reduced visual acuity, potentially reducing patient safety...

Peritoneal dialysis (PD) is an effective renal replacement therapy for the treatment of end-stage renal disease. Patients on PD undergoing abdominal open surgery often fail to resume PD. Laparoscopic surgery has recently become a serious alternative to open surgery in patients on PD to treat different abdominal pathologies. However, only a few studies have reported successful procedures without Tenckhoff catheter removal. The aim of this review is to describe how a laparoscopic technique can allow PD patients to deal with abdominal surgery without shifting to hemodialysis...

Pavlos Ioannou performed an innovative surgical operation for breast cancer in Vienna University Hospital in 1861. A few years later, after his return to Greece, an operation performed on his closest friend's child, which led to fatal complications, led him to retire from surgical practice. William Halsted travelled to Europe in order to master European surgery, including at Vienna University, and about 20 years later he published his famous method for radical mastectomy, which appears to be identical to Ioannou's operation...

Professor Sergei Semjonovic Golovin (1866-1931) is considered as one of the founders of ophthalmology in Russia. He received a worldwide reputation thanks to his achievements in ocular surgery and pathology. He introduced new surgical techniques such as Golovin's operation (Exenteratio orbitosinualis), Golovin's osteoplastic frontal sinus operation, ligation of orbital veins, and opticociliary neurectomy. He also introduced his "cytotoxic theory" to interpret sympathetic ophthalmia. He was a reputable professor of ophthalmology...

BACKGROUND: Gastroparesis is a common complication after splenectomy and azygoportal disconnection, remaining a chronic debilitating disorder with considerable treatment challenges. To minimize postoperative gastroparesis, we have developed a new modified laparoscopic pyloroplasty (LP) technique for use during laparoscopic splenectomy and azygoportal disconnection (LSD). METHODS: We retrospectively evaluated the outcomes of 31 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism who underwent synchronous LSD with modified LP (n = 14) or LSD without modified LP (n = 17) between January 2015 and August 2015...

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been reported to be a new treatment strategy for patients with predicted small volumes of future liver remnant (FLR). ALPPS is associated with rapid hypertrophy of FLR but it has a high postoperative mortality and morbidity. Up to now, it is controversial to apply ALPPS in hepatocellular carcinoma, especially for patients with liver cirrhosis. METHODS: Between May 2014 and June 2015, consecutive patients who underwent ALPPS with hepatitis B-related hepatocellular carcinoma with cirrhosis carried out in our center were included into the study...

Prosthetic reinforcement reduces the recurrence rate of large paraesophageal hernias (PEH), but the use of synthetic or biosynthetic mesh in the repair remains controversial. PEH repair has reported recurrence rates of 12% to 42%, and primary repair of PEH by suture closure under tension is at high risk of disruption. Synthetic mesh use in large PEH repair has shown to reduce recurrence but can lead to problems including mesh erosion, ulceration, stricture, and dysphagia. The objective of this study was to examine the long-term safety and efficacy of Strattice biologic mesh, a porcine acellular dermal matrix, in crural reinforcement of laparoscopic large PEH repair...
