Using Vibration to Provide Force Information in Surgery
USING VIBRATION TO PROVIDE FORCE INFORMATION DURING SURGERYBell, A., *Schwaitzberg, S.D., Cao, C.G.L., Tufts University, Cambridge Health Alliance Laparoscopic surgeons receive distorted force feedback during tissue manipulation. Research shows that sensory augmentation using vibrotactile stimulation with amplitude modulation enhances performance in tissue differentiation tasks. It was hypothesized that the capacity of information transmission through vibration… Continue Reading
Preoperative Endoscopy in the Evaluation of Patients Before Bariatric Surgery
BACKGROUND: This study evaluates the diagnostic yield of esophago-gastroduodenoscopy (EGD) before bariatric surgery and its influence on the planned surgery. METHODS: Endoscopy reports of all patients having undergone an EGD at our endosurgical unit were reviewed. We identified a non-consecutive series of morbidly obese patients that had an endoscopic evaluation before their primary bariatric procedure… Continue Reading

Patient Satisfaction Best Determines the Management of Recurrent Dysphagia After Heller Myotomy for Achalasia
Heller myotomy (HM) is an effective treatment for achalasia, however failure to reliably achieve long-term palliation of dysphagia occurs in about 10%. It is unclear when and how best to manage these patients. We sought to characterize patients with recurrent dysphagia with particular focus on the management of this difficult patient population. METHODS: A prospectively… Continue Reading

Outcomes of Fundamentals of Laparoscopic Surgery (fls) Skills Training for Senior Medical Students Entering Surgical Residency
Introduction: Laparoscopic skills training is usually reserved for surgical residents who have some experience in performing open surgical procedures. This study examined the outcomes of training 4th year medical students matched in a surgical specialty (who had no prior open case experience as primary surgeon) in the skills tasks of the SAGES FLS program. Methods:… Continue Reading

Needlescopic Resection of Small Pulmonary Nodule After Preoperative Dual Localization with Hook Wire and Lipiodol
IntroductionThe needlescopic surgery using instruments with a diameter of 2-mm is devised to leave minimal scarring and reduce the need for postoperative analgesia. For needlescopic lung biopsy for small pulmonary nodule (< 20mm), accurate and convenient method for preoperative localization is necessary. The aim of this study is to evaluate the usefulness of combined mammographic… Continue Reading

‘lesssons ‘ Learned: Single Centre Experience of Single Port Cholecystectomy
Introduction: Single Port Surgery has been described and published by various authors. A recent consensus meeting and white paper from the Cleveland Clinic gave the acronym LESSS (Laparo- Endoscopic Single Site Surgery) for all such procedures. We present the largest series of single port cholecystectomies to date using the R Port (Tri port). The paper… Continue Reading

Laparoscopic Versus Open Resection of Gastrointestinal Stromal Tumors (gists)
INTRODUCTION: GISTs are the most common mesenchymal tumors of the gastrointestinal tract. Although they can occur anywhere along the gastrointestinal tract, they are most commonly identified in the stomach. Surgery is the optimal therapy in the majority of patients with non-metastatic GISTs. There is still some controversy as to the effectiveness of laparoscopic resection of… Continue Reading

Laparoscopic Surgery for Epiphrenic Diverticula: The Ideal Approach
Laparoscopy provides excellent exposure of the distal esophagus, thus is an ideal approach for most epiphrenic diverticula. This study reviews our outcomes to support this statement, which is the largest laparoscopic series to date.Methods: From 1997 to 2008, we operated on 23 patients for epiphrenic diverticula. Of these, 18 had laparoscopic diverticulectomy, myotomy, and fundoplication… Continue Reading

Laparoscopic Adrenalectomy for Primary Hyperaldosteronsim: Comparison of Clinical Response Based on Adrenal Pathology
Introduction: Primary hyperaldosteronism may be caused by adrenal hyperplasia (nodular [NH] or diffuse [DH]) or functional adenoma [FA]. We compare response of hypertension and hypokalemia for both pathologies following laparoscopic adrenalectomy. Methods: All adrenalectomies performed for hyperaldosteronsim at a single institution were retrospectively reviewed. Hypertension / hypokalemia were considered improved in patients with reduction in… Continue Reading

Effectiveness of a New Trocar System to Enable NOTES
Introduction: Natural orifice translumenal endoscopic surgery (NOTES) is a developing area of minimally invasive surgery. Fundamental challenges of NOTES include development of safe ways to perform translumenal access and maintaining visualization and spatial orientation using a stable operating platform. This study examines the functionality of a new rotary access needle (RAN) device and technique for… Continue Reading

Different Approaches for Laparoscopic Adrenalectomy Looking for a Tailored Route
Aim: to report our experience in laparoscopic adrenalectomy (LA) through anterior, lateral and submesocolic approaches .Methods: 267 patients (pts) underwent LA in our departments. The choice of the surgical route was based on patient (BMI, previous abdominal surgery) and lesion features (size, side, secreting mass, suspect malignancy). Dissection and coagulating technology did change over the… Continue Reading

Dexterous Robot for Single Incision Advanced Minimally Invasive Surgery
Introduction: This study demonstrates the feasibility of using a miniature robot platform to perform complex, single-incision, minimal access surgery, including colon resection and Nissen fundoplication. Open surgical procedures are highly invasive; single-incision laparoscopic surgery is complicated by instrument position and lack of triangulation. Using minimally invasive techniques with miniature robotic platforms offers significant clinical benefits.… Continue Reading

Blunt Thyroid Working Space Creation: A Tool to Facilitate Transaxillary Endoscopic Thyroidectomy
BACKGROUND: Endoscopic thyroidectomy has been proved to be a safe and effective alternative treatment of a benign small thyroid lesion. To perform this operation, the working space needs to be created. Initially, the space surrounding the incisions is directly made and endoscopic part is followed. The appropriate working space is then endoscopically harvested with the… Continue Reading
