RSDNet: Learning to Predict Remaining Surgery Duration from Laparoscopic Videos Without Manual Annotations [PDF]

, 2018
Accurate surgery duration estimation is necessary for optimal OR planning, which plays an important role in patient comfort and safety as well as resource optimization. It is, however, challenging to preoperatively predict surgery duration since it varies significantly depending on the patient condition, surgeon skills, and intraoperative situation. In

A Multiple-Instance Learning Approach for the Assessment of Gallbladder Vascularity from Laparoscopic Images [PDF]

arXiv, 2021
An important task at the onset of a laparoscopic cholecystectomy (LC) operation is the inspection of gallbladder (GB) to evaluate the thickness of its wall, presence of inflammation and extent of fat. Difficulty in visualization of the GB wall vessels may be due to the previous factors, potentially as a result of chronic inflammation or other diseases.

Optimal time for early laparoscopic cholecystectomy for acute cholecystitis.

JAMA Surgery, 2015
IMPORTANCE There is growing evidence in support of performing early laparoscopic cholecystectomy (LC) for acute cholecystitis. However, the definition of early LC varies from 0 through 10 days depending on the research protocol.

Implementation of a Robotic Surgical Program With the Dexter Robotic Surgery System: Initial Experiences in Cholecystectomy

World Journal of Surgery, EarlyView.
ABSTRACT Background The use of surgical robots in minimally invasive visceral surgery is increasing, with new platforms like the Dexter Robotic System. This study evaluated the implementation of Dexter in a general visceral surgery department, focusing on safety, performance, and surgeon stress in elective cholecystectomy.

Postoperative pain after laparoscopic cholecystectomy is not reduced by intraoperative analgesia guided by analgesia nociception index (ANI®) monitoring: a randomized clinical trial.

British Journal of Anaesthesia, 2015
BACKGROUND Laparoscopic cholecystectomy frequently results in significant immediate postoperative pain. A new pain monitor, analgesic nociception index (ANI®), based on heart rate variability, has recently been approved for intraoperative nociception ...

Association of a State‐Wide Alternative Payment Model for Rural Hospitals With Bypass for Elective Surgeries

Health Services Research, EarlyView.
ABSTRACT Objective This study aimed to measure the changes in rural hospital bypass for 11 common elective surgeries following the implementation of the Pennsylvania Rural Health Model (PARHM), a global budget payment model. Study Setting and Design We leveraged a natural experiment arising from the phase‐in of PHARM in Pennsylvania.

COMPARISON BETWEEN INCIDENCE OF INCISIONAL HERNIA IN LAPAROSCOPIC CHOLECYSTECTOMY AND BY SINGLE PORT

ABCD: Arquivos Brasileiros de Cirurgia Digestiva, 2018
Background: Surgeries with single port access have been gaining ground among surgeons who seek minimally invasive procedures. Although this technique uses only one access, the incision is larger when compared to laparoscopic cholecystectomy and this fact

Differentiation of skin incision and laparoscopic trocar insertion via quantifying transient bradycardia measured by electrocardiogram [PDF]

arXiv, 2019
Background. Most surgical procedures involve structures deeper than the skin. However, the difference in surgical noxious stimulation between skin incision and laparoscopic trocar insertion is unknown. By analyzing instantaneous heart rate (IHR) calculated from the electrocardiogram, in particular the transient bradycardia in response to surgical ...

Relationship of arterial and exhaled CO2 during elevated artificial pneumoperitoneum pressure for introduction of the first trocar. [PDF]

, 2011
The present study evaluated the correlation between arterial CO2 and exhaled CO2 during brief high-pressure pneumoperitoneum. Patients were randomly distributed into two groups: P12 group (n=30) received a maximum intraperitoneal pressure of 12mmHg ...
