Minilaparoscopy to reduce complications from cannula insertion in patients with previous pelvic or abdominal surgery
1Gynecologic Endoscopy and Research Center, Samsung Cheil Hospital, Sungkyunkwan University, College of Medicine, Chung-ku, Seoul, Korea.
Study Objective:
To evaluate the safety and efficacy of minilaparoscopy for visualization and adhesiolysis of intraabdominal adhesions for safe insertion of a primary umbilical cannula in patients who had previous pelvic or abdominal surgery.
Design:
Prospective, observational study (Canadian Task Force classification II-1).
Setting:
University-affiliated hospital.
Patients:
Twenty women who had previous pelvic or abdominal surgery, excluding tubal ligation and simple appendectomy.
Intervention:
Minilaparoscopy was carried for visualization and adhesiolysis at the entry site before insertion of an umbilical cannula.
Measurements And Results:
Eleven patients had Pfannenstiel scars and nine had vertical midline scars from previous surgeries (4 total abdominal hysterectomies, 13 adnexal surgery, 7 cesarean sections, 3 ectopic pregnancies, 1 ruptured appendix, 1 unknown bowel surgery). Thirteen women (65%) had had one previous surgery, five (25%) had had two, and two (10%) had had three. Nine patients (45%) had significant adhesions of omentum or intestine that required adhesiolysis. Mean operating time for minilaparoscopy was 5 minutes for 11 women who had no or minimal adhesions that did not interfere with safe insertion of the umbilical cannula and effective use of a 10-mm telescope, and 25 minutes in 9 patients who required adhesiolysis before insertion of the umbilical cannula because of dense adhesions of omentum or intestine at the entry site. No complications with minilaparoscopy occurred.
Conclusion:
Minilaparoscopy can be performed safely and effectively to reduce serious vascular or visceral injury from insertion of primary cannula in patients who had previous pelvic and/or abdominal surgery. However, conclusions cannot be derived from this study due to the small number of subjects. Further study is necessary in a larger patient population to evaluate efficacy, safety, and advantages of minilaparoscopy over other techniques. (J Am Assoc Gynecol Laparosc 6(1):91-95, 1999)
Insights
Minilaparoscopy safely visualizes and clears intraabdominal adhesions for umbilical cannula insertion in women with prior surgery. This technique reduces injury risk, though larger studies are needed to confirm efficacy.
Area of Science:
- Minimally Invasive Surgery
- Gynecologic Surgery
- Surgical Safety
Background:
- Intraabdominal adhesions are common after pelvic or abdominal surgery.
- Adhesions can complicate subsequent procedures, particularly umbilical cannula insertion.
- Minimally invasive techniques are sought to improve surgical safety.
Purpose of the Study:
- To assess the safety and efficacy of minilaparoscopy for visualizing and performing adhesiolysis.
- To evaluate the utility of minilaparoscopy for safe primary umbilical cannula insertion in patients with prior abdominal surgery.
Main Methods:
- Prospective observational study (Canadian Task Force classification II-1).
- Twenty women with a history of pelvic or abdominal surgery underwent minilaparoscopy for visualization and adhesiolysis prior to umbilical cannula insertion.
- Exclusion criteria included prior tubal ligation and simple appendectomy.
Main Results:
- Nine out of twenty patients (45%) had significant adhesions requiring adhesiolysis.
- Minilaparoscopy operating time averaged 5 minutes for uncomplicated cases and 25 minutes when adhesiolysis was needed.
- No complications related to the minilaparoscopy procedure were reported.
Conclusions:
- Minilaparoscopy appears to be a safe and effective method for reducing injury risk during umbilical cannula insertion in patients with prior abdominal surgery.
- The study's small sample size limits definitive conclusions on efficacy and advantages over other techniques.
- Further research with larger patient cohorts is recommended to validate these findings.
