Summary
Endoscopic marking aids laparoscopic surgery by visually identifying lesions. Both India ink and methylene blue are effective, with methylene blue preferred for intraoperative use.
Area of Science:
- Gastroenterology
- Surgical Endoscopy
- Minimally Invasive Surgery
Background:
- Endoscopic marking with India ink was first described in 1975 to tattoo the intestinal lumen for lesion localization during surgery.
- Laparoscopic surgery necessitates precise lesion identification due to the loss of tactile feedback.
- Carbon-based India ink offers permanent marking, while methylene blue provides a temporary, laparoscopically visible alternative.
Purpose of the Study:
- To evaluate the utility of endoscopic marking in facilitating laparoscopic gastrointestinal surgery.
- To compare the effectiveness of India ink and methylene blue for intraoperative and preoperative lesion localization.
Main Methods:
- Endoscopic marking was performed preoperatively or intraoperatively in 15 patients over two years.
- Methylene blue was used for intraoperative marking.
- India ink was reserved for cases where endoscopy preceded surgery.
Main Results:
- All endoscopic markings were clearly visualized during laparoscopy.
- The markings effectively assisted in identifying the precise locations of gastrointestinal lesions.
- Many other cases underwent endoscopic marking without subsequent surgical intervention.
Conclusions:
- Endoscopic marking is an essential technique for successful laparoscopic gastrointestinal surgery.
- The visualization of marked lesions during laparoscopy significantly aids surgical navigation and accuracy.
