Purpose:
This study was aimed to assess the feasibility of laparoscopic rectal surgery, comparing quality of surgical specimen, morbidity, and mortality.
Methods:
Prospectively acquired data from consecutive patients undergoing laparoscopic surgery for rectal cancer, at 2 minimally invasive colorectal units, operated by the same team was included. Locally advanced rectal tumors were identified as T3B or T4 with preoperative magnetic resonance imaging scans. All the patients were operated on by the same team. The 1:1 propensity score matching was performed to create a perfect match in terms of tumor height.
Results:
Total of 418 laparoscopic resections were performed, out of which 109 patients had locally advanced rectal cancer (LARC) and were propensity score matched with non-LARC (NLARC) patients. Median operation time was higher for the LARC group (270 minutes vs. 250 minutes, P=0.011). However, conversion to open surgery was done in 5 vs. 2 patients (P=0.445), reoperation in 8 vs. 7 (P=0.789), clinical anastomotic leak was found in 3 vs. 2 (P=0.670), and 30-day mortality rates was 2 vs. 1 (P>0.999) between LARC and NLARC, respectively. Readmission rate was higher in the NLARC group (33 patients vs. 19 patients, P=0.026), due to stoma-related issues. There was no statistically significant difference in the R0 resection between the 2 groups (99 patients in LARC vs. 104 patients in NLARC, P=0.284).
Conclusion
This study demonstrates that standardized approach to laparoscopy is safe and feasible in LARC. Comparable postoperative short-term clinical and pathological outcomes were seen between LARC and NLARC groups.

Purpose:
Laparoscopic approach to colonic tumor requires skill set and resources to be established as routine standard of care in most centers around the world. It presents particular challenge in country like Pakistan due to economic constrain and lack of teaching and training opportunities available for surgeons to be trained to deliver such service. The aim of this study is to look into changing practice of our institution from conventional approach of open to laparoscopic surgery for right colon cancer.
Methods:
Consecutive patients between January 2010 to December 2018 who presented to Shaukat Khanum Memorial Cancer Hospital and Research Centre with diagnosis of right colon (cecum, ascending and transverse colon) adenocarcinoma and underwent surgical resections were included in this study.
Results:
A total of 230 patients with adenocarcinoma of the right colon underwent curative resections during the study period. Of these, 141 patients (61.3%) underwent laparoscopic surgery while open resection was performed in 89 patients (38.7%). Five-year disease-free survival (DFS) of patients with American Joint Committee on Cancer (AJCC) stage III (80.9% vs. 54.8%, P = 0.021) was significantly better if these patients underwent laparoscopic surgery while a trend toward better DFS (96.7% vs. 84.1%, P = 0.111) was also observed in AJCC stage II patients, although this difference was not significant.
Conclusion
This study demonstrates the adoption of a laparoscopic approach for right colon cancer over 10 years. With a standardized approach and using the principle of oncological surgery, we incorporated this in our minimally invasive surgery practice at our institution.
