Antonis A Kousoulis, Gregory Tsoucalas
Spyridon Magginas was among the Greek doctors of the turn of the century who trained abroad with the hope of returning to their native country to offer their services. He became a professor in the "Othonion University" of Athens to promote surgery among young physicians. He was raised in an upper social class family and, reportedly, had an arrogant behaviour, which occasionally led him to have ineffective patient interactions. His patient, and an important Greek writer, Emmanuel Rhoides, nicknamed him the "surgeon beast" for neglecting his case...

BACKGROUND: Hartmann's procedure (HP) followed by reversal restoration is the first choice for treatment of diffuse diverticular peritonitis. There is no unanimous consensus regarding the use of laparoscopy to treat the same condition. METHODS: Data from 60 patients with diverticular diffuse peritonitis who underwent urgent HP followed by laparoscopic reversal were retrospectively analyzed. Patients were divided into 2 groups according to the open or laparoscopic HP (OHP, 24 patients; LHP, 36 patients)...

INTRODUCTION: Esophageal stricture is the most common complication following repair of esophageal atresia (EA). In general, these strictures are successfully managed using endoscopic techniques including bougie and balloon dilation, stenting, and chemotherapeutic agent application. If these techniques are unsuccessful, patients require segmental esophageal resection and reanastomosis or esophageal replacement. Magnetic compression anastomosis has been described in children. Herein we report our experience with magnetic compression stricturoplasty to treat refractory strictures after EA repair...

BACKGROUND: Despite modern surgical techniques, insufficient hemostasis after liver trauma is still a major cause of morbidity and mortality after injury. Therefore, efficient hemostatic agents are indicated. In this study, we evaluated the hemostatic efficacy of a novel synthetic wound adhesive (MAR-VIVO-107) based on polyurethane/polyurea, compared with a widely used fibrin adhesive (Tisseel). MATERIALS AND METHODS: Twelve German Landrace pigs were randomly assigned to 2 groups...

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...

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...

BACKGROUND: Fluorescence cholangiography using indocyanine green (ICG) can enhance orientation of bile duct anatomy during laparoscopic cholecystectomy. To ensure clear discrimination between bile ducts and liver, the fluorescence ratio between both should be sufficient. This ratio is influenced by the ICG dose and timing of fluorescence imaging. We first systematically identified all strategies for fluorescence cholangiography. Second, we aimed to optimize the dose of ICG and dosing time in a prospective clinical trial...

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator's choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applied can have a serious influence on the outcome of the procedure and the well-being of patients. The aim of this study is to investigate the variety of differences in usage of electrosurgical devices...
