Abstract:
Appendiceal mucinous neoplasm has a risk for pseudomyxoma peritonei caused by appendiceal perforation.It has been reported that laparoscopic surgery is more risky than open surgery.We investigated 4 patients who underwent laparoscopic surgery for appendiceal mucinous neoplasm.The median age was 69.5(49-85).There were 3 males and 1 female.Three cases of partial laparoscopic resection of the cecum and 1 case of ileocecal resection with lymph node dissection were performed. The pathology was low-grade mucinous neoplasm in all cases.The median hospital stay was 6 days, and there were no postoperative complications(CD Grade 3 or higher)or hospital death.As for long-term results, peritoneal pseudomyxoma developed in 1 case, which had already ruptured at the time of surgery.There were no recurrences in other cases.This result suggests that laparoscopic surgery for appendiceal mucinous neoplasm is safe with optimal selection of the procedure and a protective technique.
Insights
Laparoscopic surgery for appendiceal mucinous neoplasm appears safe in select cases. Careful procedure selection and technique minimize risks like pseudomyxoma peritonei.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- Appendiceal mucinous neoplasm carries a risk of pseudomyxoma peritonei following perforation.
- Laparoscopic surgery has been considered potentially riskier than open surgery for this condition.
Observation:
- A study examined 4 patients with appendiceal mucinous neoplasm undergoing laparoscopic surgery.
- Procedures included partial cecal resection or ileocecal resection with lymph node dissection.
- All cases involved low-grade mucinous neoplasm.
Findings:
- The median hospital stay was 6 days with no severe postoperative complications (CD Grade 3 or higher) or mortality.
- One patient developed pseudomyxoma peritonei, but the appendix had already ruptured preoperatively.
- No other recurrences were observed in the remaining patients.
Implications:
- Laparoscopic approaches for appendiceal mucinous neoplasm can be safe and effective.
- Optimal patient selection and meticulous surgical technique are crucial for successful outcomes.
- This approach may offer a viable alternative to open surgery, reducing morbidity.
