Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.0K
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...

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.9K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Area of Science:

  • Colorectal surgery
  • Surgical oncology
  • Anesthesiology

Background:

  • Transanal Endoscopic Operation (TEO) offers potential oncological advantages over flexible endoscopy for rectal lesions.
  • Flexible endoscopy's main benefit is avoiding general anesthesia.
  • This study investigates TEO under spinal anesthesia for feasibility and safety.

Purpose of the Study:

  • To assess the feasibility and safety of Transanal Endoscopic Operation (TEO) performed under spinal anesthesia.
  • To evaluate secondary outcomes including postoperative pain, vital signs, and adverse events.

Main Methods:

  • Prospective observational study of 50 consecutive patients undergoing TEO for rectal neoplasms (>20mm or recurrent).
  • TEO was performed under spinal anesthesia.
  • Primary endpoints: feasibility and safety. Secondary endpoints: pain (VAS), vital signs, opioid use, nausea/vomiting, urinary retention.

Main Results:

  • No intraoperative complications occurred in 50 patients.
  • Median operative duration was 60 minutes.
  • Zero opioid requests, minimal postoperative pain (median VAS 0), and stable vital signs were observed. One patient experienced nausea/vomiting, four had urinary retention.

Conclusions:

  • Transanal Endoscopic Operation (TEO) under spinal anesthesia is a safe and feasible procedure.
  • No conversions to general anesthesia were required.
  • Spinal anesthesia is a viable alternative for TEO, offering potential benefits for specific patient groups.
