PURPOSE: To evaluate the clinical results of an arthroscopy-assisted latissimus dorsi tendon transfer (aLD) for irreparable posterosuperior cuff tears as a primary surgery. The secondary aim of this study was to quantify the learning curve using the log-linear model. We hypothesized that aLD significantly improved shoulder function and that there was consistent reduction of the operative time in support of a learning-curve effect. METHODS: After the arthroscopic partial repair was completed, the latissimus dorsi tendon was harvested via axillary mini-open incision and fixed with a knotless anchor arthroscopically...

The convergence of technology and medicine has led to many advances in surgical training. Novel surgical simulators have led to significantly improved skills of graduating surgeons, leading to decreased time to proficiency, improved efficiency, decreased errors, and improvement in patient safety. Endoscopic sinus surgery poses a steep learning curve given the complex 3-dimensional anatomy of the nasal and paranasal cavities, and the necessary visual-spatial motor skills and bimanual dexterity. This article focuses on surgical simulation in rhinological training and how innovative high-fidelity and low-fidelity simulators can maximize resident training and improve procedural skills before operating in the live environment...

The most challenging step in sutureless scleral fixation of intraocular lens (SFIOL) is exteriorization of haptics. The conventional handshake technique has a learning curve since it involves intraocular handing over of haptics from one forceps to another. Here, we describe "extraocular needle-guided haptic insertion technique" (X-NIT), a novel technique of exteriorizing haptics that totally eliminates intraocular manipulations. This method involves sequential introduction of two bent 26-gauge needles through the sclera (pars plicata zone) into the eye which are brought out through a sclerocorneal wound...

Esophagectomy is a major surgical procedure associated with a significant risk of morbidity and mortality. Minimally invasive esophagectomy is becoming the preferred approach because of the potential to limit surgical trauma, reduce respiratory complications, and promote earlier functional recovery. Various hybrid and total minimally invasive surgical techniques have been introduced in clinical practice over the past 20 years, and minimally invasive esophagectomy has been shown equivalent to open surgery concerning the short-term outcomes...

Microsurgery is a technically demanding field with long learning curves. Robotic-assisted microsurgery has the ability to decrease these learning curves. We, therefore, sought to assess the feasibility of robotic-assisted microvascular surgery in a rat model, and whether this could be translated into a worthwhile skills acquisition exercise for residents. Twenty-eight rats underwent microvascular anastomosis. Procedures were performed by a trained microvascular surgeon with no robotic experience (n = 14), or a trained robotic surgeon with no microvascular experience (n = 14)...

INTRODUCTION: Transanal minimally invasive surgery (TAMIS) is an endoscopic operating platform for local excision of rectal neoplasms. However, it may be technically demanding, and its learning curve has yet to be adequately defined. The objective of this study was to determine the number of TAMIS procedures for the local excision of rectal neoplasm required to reach proficiency. METHODS AND PROCEDURES: All TAMIS cases performed from 07/2009 to 12/2016 at a single high-volume tertiary care institution for local excision of benign and malignant rectal neoplasia were identified from a prospective database...

OBJECTIVE: Suicide is a major concern for those afflicted by schizophrenia. Identifying patients at the highest risk for future suicide attempts remains a complex problem for psychiatric interventions. Machine learning models allow for the integration of many risk factors in order to build an algorithm that predicts which patients are likely to attempt suicide. Currently it is unclear how to integrate previously identified risk factors into a clinically relevant predictive tool to estimate the probability of a patient with schizophrenia for attempting suicide...

BACKGROUND: Experienced surgeons demonstrate improved pancreatoduodenectomy outcomes, but little is known about what distinguishes their practice. Furthermore, the concept of experience has been variably interpreted in the surgical literature. We investigated how 4 interpretations of experience influence pancreatoduodenectomy management decisions. METHODS: A survey assessing pancreatoduodenectomy practice patterns was distributed by 6 surgical societies. Regression analysis identified behaviors associated with 4 forms of experience: years in practice, surpassing the learning curve (≥50 pancreatoduodenectomies), high annual volume (≥25 pancreatoduodenectomy/year), and high career volume (>200 pancreatoduodenectomy)...

BACKGROUND: Residents life is more than hectic, it is hard to find place and time for training basic and advanced microsurgical skills. Surgical instruments, sutures can be purchased (or loaned from department) but the most expensive and space occupying device is microscope. In developing countries microscopes are used where the need is most; in operation rooms. Furthermore conventional microscope is not portable. For all mentioned reasons availability of microscope for training microsurgery is very limited...

BACKGROUND: Despite the growing interest concerning the laparo-endoscopic single-site surgery (LESS) procedure, LESS presents multiple difficulties and challenges that are likely to increase the surgeon's cognitive cost, in terms of both cognitive load and performance. Nevertheless, there is currently no objective index capable of assessing the surgeon cognitive cost while performing LESS. We assessed if gaze-based indices might offer unique and unbiased measures to quantify LESS complexity and its cognitive cost...
