Is laparoscopic surgery really effective for the treatment of colon and rectal cancer in very elderly over 80 years old? A prospective multicentric case-control assessment.

BACKGROUND: To evaluate the effectiveness of laparoscopic surgery (LCS) for colon and rectal cancer in the very elderly over 80 years old. METHODS: We performed a prospective multicentric analysis comparing patients over 80 years (Group A) and patients between 60 and 69 years (Group B) undergoing LCS for cancer from January 2008 to December 2013. Colon and rectal cancers were analyzed separately. Comorbidity and complications were classified using the Charlson comorbidity index (CCI) and the Clavien-Dindo system, respectively. Oncological parameters included tumor-free margins, number of lymph nodes harvested and circumferential resection margin. RESULTS: Group A included 96 and 33 patients, and Group B 220 and 82 for colon and rectal cancers, respectively. Groups were similar except for ASA score and CCI, as expected. There was no significant difference in operative time [colon; rectum] (180[IQR 150-200] vs 180[150-210] min; NS-180[160-210] vs 180[165-240] min; NS), estimated blood loss (50[25-75] vs 50[25-120] mL; NS-50[0-150] vs 50[25-108.7] mL; NS) and conversion rate (2.1 vs 2.7 %; NS-3.0 vs 2.4 %; NS). Timing of first stool (3[2-3.25] vs 3[2-5] dd; NS-3[2-4] vs 3[2-5] dd; NS), length of stay (7[6-8] vs 7[6-8] dd; NS-8[8-9] vs 8[7-9] dd; NS) and readmission rate (1.0 vs 0.45 %; NS-6.1 vs 1.2 %; NS) were similar. Tumor-free margins were appropriate, and positivity of CRM is poor (6.1 vs 4.9; NS). We did not record significant differences in complications rate (47.9 vs 43.6 %; NS-63.6 vs 52.4 %; NS). CONCLUSIONS: Laparoscopic surgery is effective for the treatment of colorectal cancer even in the very elderly. Age is not a risk factor or a limitation for LCS.

Totally laparoscopic resection of the splenic flexure for tumor.

Colonic tumors located at the splenic flexure are rare and show a higher occlusive risk than other colorectal cancers. The totally laparoscopic segmental resection of splenic flexure represents a challenging procedure that requires adequate technical skills and for this reason it is still not widespread and validated. Between October 2010 and March 2012, a consecutive unselected series of eight (N = 8) patients underwent totally laparoscopic splenic flexure resection at our Institute. Data on patients' demographics, disease features, operative details and short-term follow-up were prospectively recorded in a specific database and retrospectively analyzed. All the operations were performed or supervised by the same surgeon (I.S.). We used a four-port medial-to-lateral standardized technique with intracorporeal anastomosis. A selective vascular ligation was performed in all cases and the specimens were extracted through a protected incision. Perioperative care plan and surgical instrumentations were standardized. Complications were classified using the Clavien-Dindo classification system. No conversion to open surgery was registered. All cases achieved an adequate number of lymph nodes harvested (22.9 ± 5.2) and an oncologically correct resection of the tumor (proximal margin 7.0 ± 2.4 cm, distal margin 7.1 ± 2.8 cm). The mean hospital stay was 6.1 ± 1.3 days. Postoperative complication rate according to the Clavien-Dindo system was 37.5 %, but all the complications reported were grade I. We did not observe any reoperation or readmission within 60 days after discharge. Totally laparoscopic splenic flexure resection is a feasible and reproducible technique. A correct surgical indication and a standardized technique allow to perform an oncologically safe and functionally effective treatment.
