Purpose: Short-term benefits have been demonstrated for laparoscopic-assisted colectomy. However, minimally invasive surgery is still in an evolutionary phase. In demonstrating that robotic devices also are useful in laparoscopic colonic surgery, it is fundamental to prove that a single surgeon can perform almost the entire operation on his own.
Methods: A single surgeon performed forty-one, laparoscopic-assisted, colorectal resections with the assistance of a robotic device (Automated Endoscopic System for Optimal Positioning, Computer Motion) maneuvering the laparoscope. A surgical assistant was included only for the open part of the operation. Main outcome measures were conversion rate, total operating time, and percentage of assistance by a second surgeon.
Results: There were no intraoperative complications, one case of conversion to open surgery, and three postoperative complications. The total operating time ranged from 126 to 252 minutes. A single surgeon with the assistance of a robotic device was able to perform approximately 70 percent of an ileocecal resection, 70 percent of a right hemicolectomy, 80 percent of a sigmoid resection, and 85 percent of a anterior rectal resection without further help of a surgeon.
Conclusions: A single surgeon with the assistance of a computerized robotic system can complete at least two-thirds of a laparoscopic-assisted, colorectal resection on his own. The use of a robotic device in laparoscopic-assisted, colonic surgery is safe, efficient, and feasible, and will prove even more so in future. This also will result in a patient-driven demand for high-standard, minimally invasive surgery.

Purpose: Previous studies have shown that subtrochanteric femoral fractures treated with intramedullary nails might lead to varus-procurvatum malalignment. Similar results have been reported when using antegrade intramedullary lengthening nails (ILNs). The purpose of our study is to examine if antegrade telescoping intramedullary lengthening nails lead to varus-procurvatum malalignment of the proximal femur and what are possible predictors of that shift.

This study aimed to evaluate early clinical outcomes following treatment with K-wire or IM fixation.
Methods: A retrospective review of all proximal phalanx fractures treated surgically at a single center by multiple surgeons was performed from May 1, 2019 to March 1, 2024.
Meta-analyses of mouse and human prostate single-cell transcriptomes reveal widespread epithelial plasticity in tissue regression, regeneration, and cancer.

Background: Despite extensive analysis, the dynamic changes in prostate epithelial cell states during tissue homeostasis as well as tumor initiation and progression have been poorly characterized. However, recent advances in single-cell RNA-sequencing (scRNA-seq) technology have greatly facilitated studies of cell states and plasticity in tissue maintenance and cancer, including in the prostate.
Methods: We have performed meta-analyses of new and previously published scRNA-seq datasets for mouse and human prostate tissues to identify and compare cell populations across datasets in a uniform manner.
The learning curve for laparoscopic-assisted single-port mediastinoscopic esophagectomy: an analysis of proficiency.
BMC Surg

Department of Cardiothoracic Surgery, Fifth Affiliated Hospital of Sun Yat-Sen University, No.52 East Meihua Road, Zhuhai, Guangdong Province, 519000, China.
Background: Laparoscopic-assisted single-port mediastinoscopic esophagectomy is a safe and effective emerging minimally invasive esophagectomy, but little has been reported about the learning curve for this technology. The goal of the study was to determine the number of procedures to achieve different levels of proficiency on the learning curve.
Methods: This study retrospectively analyzed data from consecutive surgeries performed by the same surgeon at the same center from 2016 to 2021.
Factors Influencing Success in Endoscopic Treatment of Grade 4-5 Primary Vesicoureteric Reflux (VUR) in Infancy and Childhood.

Introduction: There is equipoise among pediatric urologists regarding endoscopic versus surgical intervention for symptomatic Grade 4-5 Vesicoureteric Reflux (VUR), particularly in infancy. Our aim was to assess outcomes of first-line endoscopic treatment in all cases of symptomatic Grade 4-5 VUR and we hypothesised that using endoscopic Dx/HA as first line management for primary VUR would obviate the need for ureteric reimplantation in the majority of cases.
Methods: Retrospective single-surgeon analysis of consecutive patients with primary Grade 4-5 VUR over 15 years.
