Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

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...

Area of Science:

  • Colorectal surgery
  • Minimally invasive surgery
  • Gastroenterology

Background:

  • Transanal endoscopic microsurgery (TEM) is a standard for local rectal lesion excision.
  • Minimally invasive techniques aim to reduce morbidity and improve outcomes.
  • Large sessile adenomas and early rectal cancers require effective local excision methods.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of transanal single-port access microsurgery (TSPAM) for rectal adenomas.
  • To present initial experience with TSPAM in a clinical setting.
  • To assess TSPAM as a potential alternative to existing transanal surgical techniques.

Main Methods:

  • TSPAM was utilized for the transanal excision of rectal lesions.
  • The study included cases of high-grade rectal adenomas and carcinoma in situ.
  • Surgical procedures were performed using a single-port access system.

Main Results:

  • TSPAM demonstrated feasibility for the transanal excision of rectal adenomas and carcinoma in situ.
  • The technique was applied to 6 cases, including high-grade adenomas and early rectal cancer.
  • Initial experience suggests TSPAM is a viable minimally invasive option.

Conclusions:

  • Transanal single-port access microsurgery (TSPAM) is a feasible and emerging minimally invasive method for rectal lesion excision.
  • TSPAM offers a potentially affordable and widely applicable alternative to transanal endoscopic microsurgery.
  • Further studies are warranted to establish TSPAM's long-term efficacy and safety profile.
