BACKGROUND: Standard insufflators compensate for intra-abdominal pressure variations with pressure spikes. Our aim was to evaluate the impact of a stable, low-pressure pneumoperitoneum induced by a valve-less insufflator, on working space, hemodynamics, inflammation, and peritoneal physiology, in a model of laparoscopic sigmoid resection. MATERIALS AND METHODS: Twelve pigs (47 ± 3.3 kg) were equipped for invasive hemodynamic monitoring and randomly assigned to Standard (n = 6) vs...

BACKGROUND: Although there have been several reports of treating large post-endoscopic submucosal dissection (ESD) ulcers by covering them with a polyglycolic acid sheet (PGAs), this approach presents problems regarding PGAs delivery. This study assessed the usefulness of a device delivery station system (DDSS) to evaluate the appropriate and rapid PGAs coating method with DDSS. METHODS: Thirty-nine of 41 patients who were diagnosed with early gastric cancer over 20 mm in diameter and pathologically diagnosed with well-differentiated adenocarcinoma were randomly allocated to the following two groups according to delivery method: the conventional PGAs delivery group (C group) (n = 19) and the new DDSS group (DDSS group) (n = 20)...

BACKGROUND: Small seed grants strongly impact academic careers, result in future funding, and lead to increased involvement in surgical societies. We hypothesize that, in accordance with the SAGES Research and Career Development committee mission, there has been a shift in grant support from senior faculty to residents and junior faculty. We hypothesize that these junior physician-researchers are subsequently remaining involved with SAGES and advancing within their academic institutions...

BACKGROUND: Laparoscopic single anastomosis (mini-)gastric bypass (LSAGB) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remain lacking. METHODS: Between October 2001 and December 2015, 1731 morbidly obese patients who received LSAGB as primary bariatric procedure at the Min-Sheng General Hospital were recruited. Surgical outcome, weight loss, resolution of comorbidities, and late complications were followed, then compared with groups of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG)...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has increased in popularity in recent years as a definitive bariatric procedure. Despite its growing popularity worldwide, the surgical technique is not well standardized. There is a lack of evidence on the matter of the antrum size and its relation to gastric emptying and weight-loss outcomes. The aim of the study is to evaluate the influence of antrum size over gastric emptying and weight-loss outcomes. METHODS: Twenty-five patients were prospectively randomized according to the distance between the first firing and the pylorus: AR group (antrum resection-2 cm from the pylorus) and AP group (antrum preservation-5 cm from the pylorus)...

BACKGROUND AND STUDY AIM: Stricture is a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. To date, various methods have been developed to prevent stricture. However, the mechanism by which different electrosurgical unit (ESU) modes affect the formation of post-ESD stricture has not been evaluated. This study aimed to compare the degree of stricture caused by two major ESU modes (ENDO CUT mode and FORCED COAG mode) in a porcine model...

BACKGROUND: The role of EUS in managing asymptomatic pancreatic cystic lesions (PCLs) remains unresolved. We retrospectively evaluated EUS in risk stratification of PCLs when adhering to the most recent AGA guidelines. METHODS: Asymptomatic PCLs that were evaluated by EUS from January 2014 to December 2014 were retrospectively reviewed including associated cytology, fluid analysis, and relevant surgical pathology. Cross-sectional imaging reports were reviewed blindly by an expert radiologist using AGA risk stratification terminology...

BACKGROUND: The current treatment therapies for chyluria are often invasive and recurrent. Here, we investigated a novel noninvasive treatment of chyluria with high-intensity focused ultrasound (HIFU) and evaluated its clinical efficacy. METHODS: 155 patients with chyluria were treated with HIFU ablation and followed up over a period of 15 years from May 2000 to December 2015. Routine examinations including urine color observation, color Doppler ultrasound examination, blood serum test of Cr, BUN, and albumin, and detection of urinary chyle were performed before and after the treatment, 1 week, 1 and 6 months post-treatment, and followed up via telephone and other forms...

BACKGROUND: Surgical site infection (SSI) is a common complication in gastrointestinal surgery. Wound protection devices are being increasingly used in the attempt to reduce infection rates. We performed a meta-analysis to determine if wound protectors reduce the incidence of SSIs in lower gastrointestinal surgery. METHODS: MEDLINE and EMBASE databases were searched between 1946 and 2016. Randomized controlled trials comparing wound protector versus no wound protector in lower gastrointestinal surgery were included...

BACKGROUND: Quality is the major driver for both clinical and financial assessment. There remains a need for simple, affordable, quality metric tools to evaluate patient outcomes, which led us to develop the HospitAl length of stay, Readmission and Mortality (HARM) score. We hypothesized that the HARM score would be a reliable tool to assess patient outcomes across various surgical specialties. METHODS: From 2011 to 2015, we identified colorectal, hepatobiliary, upper gastrointestinal, and hernia surgery admissions using the Vizient Clinical Database...

BACKGROUND: In search of improvement of patient assessment in the postoperative phase, C-reactive protein (CRP) is increasingly being studied as an early marker for postoperative complications following major abdominal surgery. Several studies reported an attenuated immune response in minimally invasive surgery, which might affect interpretation of postoperative CRP levels. The aim of the present study was to compare the value of CRP as a predictor for major postoperative complications in patients undergoing open versus laparoscopic colorectal surgery...

BACKGROUND: Clinical and experimental data indicate that neonates are sensitive to the CO2 pneumoperitoneum. An impaired splanchnic perfusion during laparoscopy in adults has been reported. We recently confirmed that intravenous colloids improve macrocirculatory function in neonates. We aimed to determine the impact of CO2 pneumoperitoneum on the perfusion of splanchnic organs in the young including effects of colloid application. METHODS: Male piglets (n = 25) were divided into four groups: (1) neonatal controls, (2) neonates with crystalloid restitution, (3) neonates with colloidal restitution, and (4) adolescents with crystalloid restitution...

BACKGROUND: To successfully resect early gastric cancer (EGC), prediction of lymph node metastasis is essential. Beyond endoscopic submucosal dissection (ESD) indication or lymphovascular invasion (LVI) are known risk factors associated with lymph node metastasis. However, accurate prediction of tumor invasion depth or LVI is impossible before endoscopic resection even when endoscopic ultrasound is used. The aim of this study was to identify the predictive factors associated with beyond ESD indication or LVI after ESD for EGC...
