BACKGROUND: The introduction of biologic agents and laparoscopy are, arguably, the most important developments for the treatment of Crohn's disease (CD) in the last two decades. Due to the efficacy of the biologic agents in treating mild disease, it is likely that the percentage of surgery for complex cases may have increased. The objective of this study was to analyse the changing characteristics and results of surgical treatment of patients with Crohn's disease over the past 12 years...

BACKGROUND: The primary objective of this study was to evaluate the utility of CRP in early identification of post-operative complications after bariatric surgery. The ability of this marker to acutely predict post-operative complications in bariatric surgery patients has not been determined. METHODS: A retrospective chart review was conducted of adult patients who underwent a primary and revisional laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) between 2013 and 2017 at a single institution...

BACKGROUND: Our aim was to determine how objectively-measured and self-reported muscle effort and fatigue of the upper-limb differ between surgeons performing laparoscopic (LAP) and robotic-assisted (ROBOT) surgeries. METHODS: Surgeons performing LAP or ROBOT procedures at a single-institution were enrolled. Objective muscle activation and self-reported fatigue were evaluated, and comparisons were made between approaches. Muscle activation of the upper trapezius (UT), anterior deltoid (AD), flexor carpi radialis (FCR), and extensor digitorum (ED) were recorded during the surgical procedure using Trigno wireless surface electromyography (EMG)...

BACKGROUND: Failure or complications following laparoscopic adjustable gastric banding (LAGB) may necessitate band removal and conversional surgery. Band position and band-induced chronic vomiting create ideal conditions for de novo hiatal hernia (HH) formation. HH presence impedes and complicates conversional surgery by obscuring crucial anatomical landmarks and hindering precise gastric sleeve or pouch formation. The aim of this study was to evaluate the incidence of a HH in patients with an LAGB undergoing conversion compared to patients undergoing primary bariatric surgery (BS)...

BACKGROUND: Laparoscopic groin hernia repair has become increasingly popular. In Denmark, all groin hernia repairs are registered in the Danish Hernia Database. However, many surgical technical parameters are not registered in neither the hernia database nor in other national registries or the patient files. Our aim was to characterize differences in surgical techniques and variations in convalescence recommendations in laparoscopic groin hernia repair that are not available elsewhere...

INTRODUCTION: Roux-en-Y gastric bypass (RYGB) has been the most common surgical operation used to treat obesity and its inherent co-morbidities. Intussusception with bowel obstruction after RYGB is a rare complication and its physiopathology remains unclear. The diagnosis is generally based on typical image of computed tomography (CT) scan and a surgical exploration is generally recommended. CASE PRESENTATION: A 54-year-old female patient with history of a gastric bypass six years before, presented herself on the emergency department with acute onset of abdominal pain, nausea, and nonbilious vomiting...

BACKGROUND: In laparoscopic surgery, image quality can be severely degraded by surgical smoke, which not only introduces errors for the image processing algorithms (used in image guided surgery), but also reduces the visibility of the observed organs and tissues. To overcome these drawbacks, this work aims to remove smoke in laparoscopic images using an image preprocessing method based on a variational approach. METHODS: In this paper, we present the physical smoke model where the degraded image is separated into two parts: direct attenuation and smoke veil and propose an efficient variational-based desmoking method for laparoscopic images...

OBJECTIVE: To determine whether laparoscopic surgery is noninferior to open surgery for rectal cancer in terms of quality of surgical resection outcomes. BACKGROUND: Randomized clinical trials (RCTs) have evaluated the oncologic safety of laparoscopic versus open surgery for rectal cancer with conflicting results. Prior meta-analyses comparing these operative approaches in terms of quality of surgical resection aimed to demonstrate if one approach was superior. However, this method is not appropriate and potentially misleading when noninferiority RCTs are included...

Surgery is traditionally taught by using Halsteadian principle, which includes "see one, do one, teach one". This principle relies on sheer volume of surgical exposure rather than a specific course structure. Simulation in minimally invasive surgery allows the learner to practice new motor skills in a safe and stress free environment outside the operating room, thereby decreasing the learning curve. A non-structured exhaustive MEDLINE search was done using MeSH words: "Simulation, Urological Training, Training Models, Laparoscopy Urology, Laparoscopic Skill, Endotrainer, Surgical Simulators, Simulator Validation"...

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial (mesenchymal) tumors of the gastrointestinal tract. Although GISTs appear as solid and well-circumscribed lesions in most patients, they may also appear as solid- cystic (mixed) or pure cystic lesions due to reasons like intra-tumor hemorrhage and necrosis in a very small percentage of patients. Hence, cystic GISTs mostly lead to a diagnostic dilemma. In this paper we aimed to report a case of pure cystic giant GIST that was drained percutaneously twice after being misdiagnosed as a mesenteric cyst...

Robot-assisted distal pancreatectomy (RADP) has been developed with the aim of improving surgical quality and overcoming the limitations of laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for pancreatic resections. A systematic search was performed in the PubMed, EMBASE, Cochrane Library, Web of Science, and China Biology Medicine databases up to December 2016 for studies that compared the surgical outcomes of RADP vs. LDP or ODP for pancreatic resections. The weighted mean differences, odds ratios and 95% confidence intervals were calculated, and the data were combined using the random-effects model...

BACKGROUND AND OBJECTIVE: Laparoscopic surgery offers the potential for video recording of the operation, which is important for technique evaluation, cognitive training, patient briefing and documentation. An effective way for video content representation is to extract a limited number of keyframes with semantic information. In this paper we present a novel method for keyframe extraction from individual shots of the operational video. METHODS: The laparoscopic video was first segmented into video shots using an objectness model, which was trained to capture significant changes in the endoscope field of view...

BACKGROUND: Sevoflurane and desflurane are widely used in balanced anaesthesia in combination with opioid analgesics. The opioid remifentanil is frequently chosen because of its extremely rapid pharmacokinetics. However, intraoperative high-dose remifentanil is associated with increased postoperative pain and rescue analgesic use owing to acute tolerance and opioid-induced hyperalgesia. This study aimed to compare intraoperative remifentanil requirements during equi-minimum alveolar concentration (MAC) sevoflurane and desflurane anaesthesia via surgical pleth index-guided remifentanil administration...
