RESUMEN
BACKGROUND: Pure natural orifice transluminal endoscopic surgery (NOTES) for colorectal cancer is a complex procedure and rarely used in clinical practice because of the ethical concerns and technical challenges, including loss of triangulation, in-line orientation, and instrument collision. Transvaginal (v) NOTES, however, can overcome these technical challenges. We report a case of pure vNOTES right hemicolectomy for colon cancer, attached with surgical video. CASE SUMMARY: A 65-year-old woman with a 2-year history of intermittent diarrhea was diagnosed with ascending colon adenocarcinoma by colonoscopy and biopsy. Pure vNOTES right hemicolectomy was performed with complete mesocolic excision by well-experienced surgeons. The operative time was 200 min and the estimated blood loss was 30 mL. No intraoperative or postoperative complications occurred within 30 d after the surgery. The visual analog scale pain score on postoperative day 1 was 1 and dropped to 0 on postoperative days 2 and 3. The patient was discharged at postoperative day 6. The pathologic specimen had sufficient clear resection margins and 14 negative harvested lymph nodes. CONCLUSION: vNOTES right hemicolectomy, performed by well-experienced surgeons, overcomes the technical challenges of pure NOTES and may be feasible for colon cancer.
RESUMEN
Local recurrent rectal cancer (LRRC) is located in the pelvis with or without distant metastasis. It is life-threatening for patients with rectal cancer. Despite the addition of imaging technology, preoperative neoadjuvant therapy and total mesorectal excision, loco-regional relapse still occurs with an incidence as high as 10% in recent reports. Non-operative approaches to management such as radiotherapy and chemotherapy can only prolong survival time by 1 year. Improvements in surgical techniques, reconstruction methods and management of preoperative complications have helped increase the cure rate of patients with recurrent rectal cancer. Multimodality therapy based on surgery is the key of treating LRRC. This review article highlights the progress in surgical managements for local recurrent rectal cancer.
