Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Background:

Laparoscopic surgery often requires a dedicated assistant for camera control, potentially increasing procedure time and complexity.
Real-time, intuitive control of the laparoscopic vision field is crucial for surgical precision and efficiency.

Purpose of the Study:

To evaluate the clinical and experimental feasibility of the Postural Mechatronic Assistance Solo Surgery (PMASS) system.
To assess the advantages and disadvantages of surgeon-controlled, real-time laparoscopic vision assistance.
To document surgical times and potential complications during procedures utilizing the PMASS system.

Main Methods:

A prospective study involving thirteen laparoscopic procedures (appendicectomy, ovarian cystectomy, sterilization).

Utilizing a 3D Printed Laparoscopic Nissen Fundoplication Model to Shorten a Resident's Learning Curve

Published on: August 15, 2025

Surgeons utilized the PMASS system for direct, intuitive, real-time control of the laparoscopic camera.

Surgical and delay times were meticulously recorded for each procedure.

Main Results:

Surgeons successfully self-navigated the laparoscopic vision field in real-time across all procedures, with no visual tremor.
Average surgical times were recorded: appendicectomy (45 ± 4.5 min), cystectomy (49 ± 3.5 min), sterilization (22 ± 2 min).
No intraoperative or postoperative complications were observed; PMASS setup and removal were efficient.

Conclusions:

The PMASS system facilitates autonomous, real-time visual self-assistance for surgeons in solo laparoscopic procedures.
The mechatronic assistance effectively reduces latency and improves surgical control without adverse effects on performance or morbidity.
PMASS demonstrates a promising approach to enhancing efficiency and autonomy in minimally invasive surgery.
