Value of microlaparoscopy in the diagnosis of right iliac fossa pain
1Department of Surgery A, European Institute of TeleSurgery (IRCAD-EITS), Hôpitaux Universitaires, Strasbourg, France.
Background:
The possibility of performing minimally invasive exploration of the abdomen could avoid unnecessary appendectomies. Micro-optics and instruments of 2 mm in diameter allow this type of exploration, but the feasibility and the accuracy of the diagnosis resulting from this method have not been evaluated.
Methods:
A prospective study of 36 patients (11 men and 25 women) operated on for acute right iliac fossa pain was carried out. The abdomen was explored with a 2 mm optic and with a 10 mm optic in order to characterize the aspect of the appendix. The results were compared with the postoperative pathologic findings of the appendix.
Results:
The micro-optic procedure failed in 3 patients. The appendix was visualized in 26 patients: in 18 patients through the needle-optic alone, 8 patients requiring additional instruments. The appendix was visualized in all cases with the 10 mm optic. Appendectomy was performed in 34 patients: with microinstruments in 6, with 5 mm instruments in 26, and through a MacBurney incision in 2. The appendix was not removed in 2 patients. A correct diagnosis was made by microlaparoscopy and confirmed by the pathology in 21 patients (58%), made and confirmed in 32 patients with a 10 mm optic (89%). Minor complications included a cecal wall insufflation in 1 patient and a peroperative hemorrhage on a 2 mm port site in another with an uneventful postoperative course. One postoperative parietal hematoma required reoperating removal. No mortality was observed.
Conclusions:
The low quality of the image obtained with microlaparoscopy does not permit safely evaluating the aspect of the appendix in case of acute right iliac pain. This method is not recommended for routine abdominal exploration.
Insights
Microlaparoscopy using 2 mm optics for diagnosing acute right iliac pain has low diagnostic accuracy. This minimally invasive approach is not recommended for routine abdominal exploration due to image quality limitations.
Area of Science:
- Surgical Innovation
- Diagnostic Accuracy
- Minimally Invasive Surgery
Background:
- Minimally invasive abdominal exploration could reduce unnecessary appendectomies.
- Micro-optics (2 mm) enable exploration but require feasibility and accuracy assessment.
Purpose of the Study:
- Evaluate the feasibility and diagnostic accuracy of 2 mm micro-optics for acute right iliac fossa pain.
- Compare diagnostic performance with standard 10 mm laparoscopy.
Main Methods:
- Prospective study of 36 patients with acute right iliac fossa pain.
- Abdominal exploration using 2 mm and 10 mm optics to visualize the appendix.
- Comparison of laparoscopic findings with postoperative pathological results.
Main Results:
- Microlaparoscopy failed in 3 patients; the appendix was visualized in 26 (72%) using 2 mm optics.
- Diagnostic accuracy was 58% with 2 mm optics versus 89% with 10 mm optics.
- Minor complications included cecal insufflation and port site hemorrhage; one postoperative hematoma required reoperation.
Conclusions:
- Low image quality from 2 mm microlaparoscopy hinders safe evaluation of the appendix in acute right iliac pain.
- This micro-optic method is not recommended for routine abdominal exploration.
