To construct patient-specific physical three-dimensional (3D) models of renal units with materials that approximates the properties of renal tissue to allow pre-operative and robotic training surgical simulation, 3D physical kidney models were created (3DSystems, Rock Hill, SC) using computerized tomography to segment structures of interest (parenchyma, vasculature, collection system, and tumor). Images were converted to a 3D surface mesh file for fabrication using a multi-jet 3D printer. A novel construction technique was employed to approximate normal renal tissue texture, printers selectively deposited photopolymer material forming the outer shell of the kidney, and subsequently, an agarose gel solution was injected into the inner cavity recreating the spongier renal parenchyma...

BACKGROUND: It is unknown why some chronic subdural haematomas (CSDH) grow and require surgery, whilst others spontaneously resolve. Although a relatively small CSDH volume (V) reduction may induce resolution, V% reduction is often unreliable in predicting resolution. Whilst CSDH evolve distinctive inner and outer neo- membranes (IM and OM), the OM likely dominates the dynamic growth-resorption equilibrium. If other factors remain constant, one previous hypothesis is that resorption could fail as the surface area (SA):V ratio decreases when CSDH exceed a 'critical size'...

Fragmented and uncoordinated care is the third highest driver of U.S. healthcare costs. Although less than 10% of patients experience uncoordinated care, these patients represent 36% of total healthcare costs; care management interaction makes a significant impact on the utilization of healthcare dollars. A literature search was conducted to construct a model of care coordination for elective surgical procedures by collecting best practices for acute, transitions, and post-acute care periods. A case study was used to demonstrate the model developed...

OBJECTIVE: Bilateral axillary hidradenitis is a chronic, suppurative, and scarring disease that is most effectively treated by complete excision of all hair-bearing tissues. We assessed our staged procedure for excision and placement of a split-thickness skin graft for bilateral axillary hidradenitis in terms of costs, outcomes, and timing of excision. METHOD: An IRB approved retrospective case analysis was performed on patients that underwent bilateral axillary hidradenitis skin excision with eventual placement of split-thickness skin grafting using the current LSUHSC/University Health hidradenitis surgical treatment protocol...

INTRODUCTION: While preoperative chemotherapy (pCT) is utilized in many intra-abdominal cancers, the use of pCT among patients with intrahepatic cholangiocarcinoma (ICC) remains ill defined. As such, the objective of the current study was to examine the impact of pCT among patients undergoing curative-intent resection for ICC. METHODS: Patients who underwent hepatectomy for ICC were identified from a multi-institutional international cohort. The association between pCT with peri-operative and long-term clinical outcomes was assessed...

An apprenticeship model has traditionally been used in procedural and surgical teaching. As the pressures of work hours and patient outcome monitoring increase, surgical teachers need a more flexible plan for teaching procedural skills. We attempt to delineate a program of pre-, intra-, and post- procedural teaching that can be used in the field of ophthalmology to maximize a resident's skill acquisition in a constructive learning environment.We review the literature on surgical teaching from within ophthalmology as well as other surgical fields and combine this with teaching experience in an ophthalmic surgical training program to produce a collection of procedural teaching guidelines...

A leading cause of maternal mortality in the first trimester is hemorrhage due to a ruptured ectopic pregnancy. With the advent of tube salvage surgery, ectopic pregnancies can be removed while ensuring hemostasis and preserving the integrity of the fallopian tube. A major drawback of tube salvage surgery is the significant risk of persistent trophoblastic tissue being left behind. We report a case of a 30year old female who presented to the ED with acute abdomen and hemoperitoneum due to a ruptured ectopic pregnancy...

BACKGROUND: Sentinel lymph node (SLN) mapping has emerged as a promising solution to the ongoing debate regarding lymphadenectomy in the initial surgical management of endometrial cancer. Currently, little is known about its possible impact on location of disease recurrence compared to systematic lymphadenectomy. METHODS: In this retrospective study, 472 consecutive patients with endometrial cancer who underwent either SLN mapping (SLN cohort, n=275) or systematic lymphadenectomy (LND cohort, n=197) from sequential, non-overlapping historical time points were compared...

BACKGROUND: Calcineurin-inhibitor-induced pain syndrome (CIPS) was used as a reference in the literature as reflex sympathetic dystrophy syndrome related to calcineurin inhibitors. Much of the literature describes CIPS that occurred after kidney and bone marrow transplantation. We describe a rare case of CIPS in induction immunosuppression before kidney transplantation, under administration of an anti-rheumatoid drug. METHODS: A 53-year-old woman had pre-status of ABO-incompatible living kidney transplantation...

BACKGROUND: Optimal treatment for established renal failure is living donor kidney transplantation. However this pathway exposes healthy individuals to significant reduction in nephron mass via major surgical procedure. Laparoscopic donor nephrectomy is now the most common method for live donor transplantation, reducing both donor post-operative pain and recovery time. However this procedure exposes kidneys to additional haemodynamic stresses. It has been suggested that donor hydration-particularly the use of preoperative intravenous fluids-may counteract these stresses, reducing subclinical acute kidney injury and ultimately improving long-term renal function...
