Minilaparoscopy-assisted transrectal low anterior resection (LAR): a preliminary study
Surgical Endoscopy, 07/27/2012
Lacy AM et al. – In this preliminary report, transrectal minilaparoscopy–assisted low anterior resection was feasible and safe. Lateral/end–to–end anastomoses can be considered an interesting alternative to the double–stapling technique. However, it is necessary to further study and develop these procedures, along with careful patient selection, before transrectal low anterior resection may be considered for routine clinical use.Methods
- Between March and April 2012 three selected patients underwent transrectal minilaparoscopy–assisted natural orifice surgery total mesorectal excision for rectal cancer.
- All the oncologic principles of open/laparoscopic low anterior resection for rectal cancer were strictly fulfilled.
- Two patients underwent neoadjuvant treatment.
- Laparoscopic visualization and assistance was provided through one 10–mm umbilical port and two ports, one of which was used as stoma site (5 mm) and the other as a drain site (2 mm needle port).
- The specimen was transected transanally followed by the confection of double purse–string lateral/end–to–end anastomoses.
- There were no intraoperative complications.
- Mean operative time was 143 min.
- Oral intake was initiated on the second postoperative day.
- Patients were discharged home by day 5.
- The pathology unit confirmed that distal and circumferential margins were free of tumor invasion, and quality of mesorectum resection was reported satisfactory.
- One patient had to be readmitted because of severe dehydration due to increased ileostomy output.
- The patient was discharged at the third day after the readmission without renal failure.
