A Neural Network Model for Learning 3D Object Representations Through Haptic Exploration.

Humans initially learn about objects through the sense of touch, in a process called "haptic exploration." In this paper, we present a neural network model of this learning process. The model implements two key assumptions.

Risk Factors for Appendiceal Cancer After Appendectomy.

Background: Appendiceal cancer (AC) is a rare malignancy usually diagnosed incidentally after appendectomy. Risk factors for AC are poorly understood. We sought to provide a descriptive analysis for patients with AC discovered after appendectomy for acute appendicitis (AA).

Evaluation of Pelvic Anastomosis by Endoscopic and Contrast Studies Prior to Ileostomy Closure: Are Both Necessary? A Single Institution Review.

Contrast enema is the gold standard technique for evaluating a pelvic anastomosis (PA) prior to ileostomy closure. With the increasing use of flexible endoscopic modalities, the need for contrast studies may be unnecessary. The objective of this study is to compare flexible endoscopy and contrast studies for anastomotic inspection prior to defunctioning stoma reversal.

Decisional Conflict and Knowledge Among Patients With Varicocele Seeking Treatment for Infertility.

Objective: To study disease-specific knowledge and decisional quality in men with varicocele being counseled for infertility.

Materials And Methods: An instrument designed to measure decisional quality by evaluating disease-specific knowledge, decisional conflict, and the impression that shared decision-making was administered to 92 men identified to have a varicocele seeking their initial infertility consultation. Mean scores on disease-specific knowledge questionnaire, prevalence of decisional conflict, and impact of consultation on preferred infertility treatment were analyzed.

Improved survival with adjuvant chemotherapy in locally advanced rectal cancer patients treated with preoperative chemoradiation regardless of pathologic response.

Objective: The aim of this study is to examine the effect of postoperative chemotherapy on survival in patients with stage II or III rectal adenocarcinoma who undergo neoadjuvant chemoradiation (CRT) and surgical resection.

Methods: A retrospective review of the National Cancer Database (NCDB) from 2006 to 2013 was performed. Cases were analyzed based on pathologic complete response (pCR) status and use of adjuvant therapy.

Vaginal Dehiscence and Evisceration After Robotic-assisted Radical Cystectomy: A Case Series and Review of the Literature.

Objective: To describe a rare complication in 5 women who had vaginal prolapse, dehiscence, and/or evisceration after having undergone robotic-assisted radical cystectomy with creation of ileal conduit urinary diversion. Radical cystectomy is the standard of care in the extirpative treatment for muscle invasive urothelial carcinoma. Anterior exenteration in the female patient requires removal of the anterior vaginal wall, urethra, uterus, and adnexa which results in significant changes to the pelvic floor.

Efficacy of a preprostatectomy multi-modal penile rehabilitation regimen on recovery of postoperative erectile function.

To evaluate the efficacy of a novel, multi-modal, preoperative approach to postprostatectomy penile rehabilitation (PR), we performed a retrospective review of patients who underwent nerve-sparing robotic-assisted laparoscopic prostatectomy (NS-RALP). All patients were evaluated at a comprehensive, academic sexual medicine clinic between 2016 and 2017. The "prehabilitation" PR group (n = 106) consisted of men who were seen in the pre-op period and began tadalafil and L-citrulline 2 weeks prior to surgery.

Sixty years in the making: collagenase Clostridium histolyticum, from benchtop to FDA approval and beyond.

Purpose: The introduction of collagenase Clostridium histolyticum (CCH) as the first and only FDA-approved non-surgical treatment for Peyronie's disease (PD) has been an important step in its management. Our aim is to provide an overview of the historical origins of CCH and its development through FDA approval and beyond for the treatment of PD.

Methods: A PubMed search using the terms Peyronie OR Peyronie's AND collagenase and limited to clinical research studies resulted in 24 articles that were examined for the current review.

A modified technique for intralesional injection of collagenase Clostridium histolyticum for Peyronie's disease results in reduced procedural morbidity using a standardized hematoma classification rubric.

Purpose: Early clinical trials of injectable collagenase Clostridium histolyticum (CCh) for Peyronie's disease (PD) demonstrated safety and efficacy. Since then, modified injection protocols have been proposed. Adverse events-such as bruising, swelling, hematoma, and corporal rupture-exceed 50% in many studies, but lack of standardization of hematoma severity limits conclusions about the relative safety of protocols.

Immersive Telepresence and Remote Collaboration using Mobile and Wearable Devices.

The mobility and ubiquity of mobile head-mounted displays make them a promising platform for telepresence research as they allow for spontaneous and remote use cases not possible with stationary hardware. In this work we present a system that provides immersive telepresence and remote collaboration on mobile and wearable devices by building a live spherical panoramic representation of a user's environment that can be viewed in real time by a remote user who can independently choose the viewing direction. The remote user can then interact with this environment as if they were actually there through intuitive gesture-based interaction.

Ileocolic Resection for Crohn's Disease: A Minimally Invasive Approach Claims Its Place.

Ileocolic resection is the most common operation performed for Crohn's disease patients with terminal ileum involvement. We sought to evaluate the outcomes in Crohn's disease patients who underwent open ileocolic resection (OIC) and laparoscopic ileocolic resection (LIC) by using the ACS-NSQIP database from 2006 to 2015. Of 5670 patients, 48.

Laparoscopic loop ileostomy reversal with intracorporeal anastomosis is associated with shorter length of stay without increased direct cost.

Background: Laparoscopic ileostomy closure with intracorporeal anastomosis offers potential advantages over open reversal with extracorporeal anastomosis, including earlier return of bowel function and reduced postoperative pain. In this study, we aim to compare the outcome and cost of laparoscopic ileostomy reversal (utilizing either intracorporeal or extracorporeal anastomosis) with open ileostomy reversal.

Methods: A retrospective review of sequential patients undergoing elective loop ileostomy reversal between 2013 and 2016 at a single, high-volume institution was performed.

Association of Compensation From the Surgical and Medical Device Industry to Physicians and Self-declared Conflict of Interest.

Importance: Surgical and medical device manufacturers have a cooperative relationship with clinicians. When evaluating published works, one should assess the integrity and academic credentials of the authors, who serve as putative experts. A relationship with a relevant manufacturer may increase the potential risk for bias in relevant studies.

An endoscopic mucosal grading system is predictive of leak in stapled rectal anastomoses.

Background: Anastomotic leak is a devastating postoperative complication following rectal anastomoses associated with significant clinical and oncological implications. As a result, there is a need for novel intraoperative methods that will help predict anastomotic leak.

Methods: From 2011 to 2014, patient undergoing rectal anastomoses by colorectal surgeons at our institution underwent prospective application of intraoperative flexible endoscopy with mucosal grading.

Respiratory complications after colonic procedures in chronic obstructive pulmonary disease: does laparoscopy offer a benefit?

Background: Patients with severe chronic obstructive pulmonary disease (COPD) are at a higher risk for postoperative respiratory complications. Despite the benefits of a minimally invasive approach, laparoscopic pneumoperitoneum can substantially reduce functional residual capacity and raise alveolar dead space, potentially increasing the risk of respiratory failure which may be poorly tolerated by COPD patients. This raises controversy as to whether open techniques should be preferentially employed in this population.

Randomized Clinical Trial of Epidural Compared with Conventional Analgesia after Minimally Invasive Colorectal Surgery.

Background: The effectiveness of thoracic epidural analgesia (EA) vs conventional IV analgesia (IA) after minimally invasive surgery is still unproven. We designed a randomized controlled trial comparing EA with IA after minimally invasive colorectal surgery.

Study Design: A total of 87 patients who underwent minimally invasive colorectal procedures at a single institution between 2011 and 2014 were enrolled.

Defining the Role of Minimally Invasive Proctectomy for Locally Advanced Rectal Adenocarcinoma.

Objective: National examination of open proctectomy (OP), laparoscopic proctectomy (LP), and robotic proctectomy (RP) in pathological outcomes and overall survival (OS).

Background: Surgical management for rectal adenocarcinoma is evolving towards utilization of LP and RP. However, the oncological impacts of a minimally invasive approach to rectal cancer have yet to be defined.

Lymph Node Positivity in Appendiceal Adenocarcinoma: Should Size Matter?

Background: The management algorithm for appendiceal adenocarcinoma is not well defined. This study sought to determine whether tumor size or depth of invasion better correlates with the presence of lymph node metastases in appendiceal adenocarcinoma, and to compare these rates with colon adenocarcinoma.

Study Design: A retrospective review of the National Cancer Database was performed to identify patients with appendiceal or colonic adenocarcinoma from 2004 to 2013 who underwent surgical resection.

Incidence, Risk Factors, and Trends of Motor Peripheral Nerve Injury After Colorectal Surgery: Analysis of the National Surgical Quality Improvement Program Database.

Background: Motor peripheral nerve injury is a rare but serious event after colorectal surgery, and a nationwide study of this complication is lacking.

Objective: The purpose of this study was to report the incidence, trends, and risk factors of motor peripheral nerve injury during colorectal surgery.

Design: The National Surgical Quality Improvement Program database was surveyed for motor peripheral nerve injury complicating colorectal procedures.

Body Mass Index Significantly Impacts Outcomes of Colorectal Surgery.

There are limited data regarding the association between body mass index (BMI) and colorectal surgery outcomes. We sought to evaluate the effect of BMI on short-term surgical outcomes in colon and rectal surgery patients in the United States. The American College of Surgeons National Surgery Quality Improvement Project database was used to identify all patients who underwent colon or rectal resection from 2005 to 2013.

Comparison of Times to Ureteral Efflux after Administration of Sodium Fluorescein and Phenazopyridine.

Purpose: There is currently a national shortage of indigo carmine. In efforts to identify the most efficient aid for visualizing ureteral efflux intraoperatively we investigated the time to excretion of phenazopyridine vs a newly identified alternative, sodium fluorescein.

Materials And Methods: We analyzed prospectively collected data on a cohort of women who underwent pelvic reconstructive surgery in 2015.

Keyhole Transsylvian Resection of Infiltrative Insular Gliomas: Technique and Anatomic Results.

Aim: Insular gliomas have traditionally been approached through variations of large frontotemporal craniotomies exposing much of the Sylvian fissure. Due to the importance of many structures exposed by such an approach, a less-invasive approach to these lesions is a viable alternative for resection. We present the technique and results of our keyhole transsylvian approach to remove infiltrating insular tumors.
