Introduction:
Extraperitoneal cysts in the pelvis adjacent to the rectum are rare entities. They are of vague etiology, and the pathologic types of the acquired variety are dermoid, epidermoid, and teratoma. As far as we know, laparoscopic excision of a retrorectal epidermoid cyst has never before been reported.
Case Report:
The patient was an elderly lady with a large pelvic cyst and another large cyst in the perineum, which displaced the vagina and the anus. Laparoscopy was performed; the pelvic cyst was punctured and then dissected out. The perineal extension of the cyst was excised via a perineal approach. The patient had an uneventful recovery and was discharged on the 4th postoperative day. Histopathologically, the cyst was of the epidermoid type. Follow-up after 26 months revealed no recurrence.
Discussion:
Our case presented a diagnostic dilemma. Laparoscopic excision was tedious, though we completed the procedure successfully. Precaution was taken to avoid spillage of the contents and also to avoid injury to vital structures nearby, such as the iliac vessels and ureter. It is feasible to laparoscopically excise retrorectal cysts with a careful and meticulous dissection.
Conclusions:
The major advantages are rapid recovery with minimal morbidity and excellent cosmesis.
Insights
This case report details the first laparoscopic excision of a retrorectal epidermoid cyst. The minimally invasive approach resulted in a successful outcome with rapid recovery and minimal morbidity for the patient.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Gynecologic Oncology
Background:
- Retrorectal cysts, including epidermoid cysts, are rare pelvic masses.
- Their etiology is often unclear, and they can present diagnostic challenges.
- Laparoscopic excision of these cysts has not been previously documented.
Observation:
- An elderly female presented with large pelvic and perineal cysts causing displacement of pelvic organs.
- Laparoscopic techniques were employed for the pelvic cyst, followed by perineal excision of the extension.
- Histopathology confirmed the cyst to be of the epidermoid type.
Findings:
- Successful laparoscopic excision of a retrorectal epidermoid cyst was achieved.
- The procedure required meticulous dissection to avoid injury to adjacent vital structures.
- The patient experienced an uneventful recovery with no recurrence at 26-month follow-up.
Implications:
- Laparoscopic excision is a feasible and effective treatment for retrorectal epidermoid cysts.
- This approach offers advantages such as reduced morbidity and improved cosmetic outcomes.
- Further research may explore the broader application of minimally invasive techniques for similar rare pelvic pathologies.
