RESUMO
Intersphincteric resection (ISR) with coloanal anastomosis is an oncologically safe anus-preserving technique for very low-lying rectal cancers. Most studies focused on oncological and functional outcomes of ISR with very few evaluating long-term postoperative anorectal complications. Full-thickness prolapse of the neorectum is a relatively rare complication. This report presents the case of a 70-year-old woman presenting with full-thickness prolapse of the side limb of the side-to-end coloanal anastomosis occurring 2 weeks after the stoma closure and 2 months after a robotic partial ISR performed with the Da Vinci single-port platform (Intuitive Surgical System Inc.). The anastomosis was revised through resection of the side limb and conversion of the side-to-end anastomosis into an end-to-end handsewn anastomosis with interrupted stitches. This study describes the first case of full-thickness prolapse of the side limb of the side-to-end handsewn coloanal anastomosis following ISR. Moreover, a revision of all reported cases of post-ISR full-thickness and mucosal prolapse was performed.
RESUMO
BACKGROUND: Patients undergoing colorectal cancer surgery may require a blood transfusion. However, blood transfusions are associated with postoperative complications and long-term oncologic outcomes. Patient blood management (PBM) is an evidence-based multimodal approach for blood transfusion optimisation. We sought to investigate the effects of PBM implementation in blood transfusion practice and on short-term postoperative outcomes. MATERIALS AND METHODS: This study retrospectively reviewed data from 2,080 patients who had undergone colorectal cancer surgery at a single centre from 2015 to 2020. PBM was implemented in 2018, and outcomes were compared between the pre-PBM (2015-2017) and the post-PBM (2018-2020) periods. RESULTS: A total of 951 patients in the pre-PBM group and 1,129 in the post-PBM group were included. The transfusion rate of the total number of packed red blood cells (PRBCs) used decreased after PBM implementation (16.3 vs 8.3%; p<0.001). The rate of appropriately transfused PRBCs increased from the pre-PBM period to the post-PBM period (42 vs 67%; p<0.001). There was no significant difference in rates of complications between the two groups (23.0 vs 21.5%; p=0.412); however, a reduction in both anastomosis leakage (5.8 vs 3.7%; p=0.026) and the length of stay after surgery (LOS) (10.3±11.2 vs 8.2±5.7 days; p<0.001) was reported after PBM implementation. DISCUSSION: The PBM programme optimised the transfusion rate in patients undergoing colorectal cancer surgery. Implementation of the PBM programme had a positive effect on postoperative length of stay and anastomosis leakage while no increase in the risk of other complications was reported.

PURPOSE: Colorectal cancer (CRC) occurs in all age groups, and the application of treatment may vary according to age. The study was designed to identify the characteristics of CRC by age. METHODS: A total of 4,326 patients undergoing primary resection for CRC from September 2006 to July 2019 were reviewed. Patient and tumor characteristics, operative and postoperative data, and oncologic outcome were compared. RESULTS: Patients aged 60 to 69 years comprised the largest age group (29.7%), followed by those aged 50 to 59 and 70 to 79 (24.5% and 23.9%, respectively). Rectal cancer was common in all age groups, but right-sided colon cancer tended to be more frequent in older patients. In very elderly patients, there were significant numbers of emergency surgeries, and the frequencies of open surgery and permanent stoma were greater. In contrast, total abdominal colectomy or total proctocolectomy was performed frequently in patients in their teens and twenties. The elderly patients showed more advanced tumor stages and postoperative ileus. The incidence of adjuvant treatment was low in elderly patients, who also had shorter follow-up periods. Overall survival was reduced in older patients with stages 0 to 3 CRC (P<0.001), but disease-free survival did not differ by age (P=0.391). CONCLUSION: CRC screening at an earlier age than is currently undertaken may be necessary in Korea. In addition, improved surgical and oncological outcomes can be achieved through active treatment of the growing number of elderly CRC patients.
