The results of this study with large number of patients over a long follow-up period suggested that laparoscopic resection for rectal cancer is safe with good long-term oncological outcomes.

This study was performed to evaluate the outcome of implementation of transanal total mesorectal excision (TaTME) for low rectal cancer in a regional hospital and in comparison to laparoscopic (Lap) TME. Methods: Consecutive patients with low rectal cancer of which the lowest border of the tumour was located beween 1 and 5 cm from the puborectalis who underwent TME at North District Hospital between January 2013 and December 2019 were included. Clinical, operative, and pathologic outcomes were compared between Lap TME and TaTME. The primary end point was complication profile. Results: Thirty-five patients underwent Lap TME and 45 patients underwent TaTME for low rectal cancer. The conversion rate of the TaTME group was significantly lower than that of the Lap TME group (4.4% vs. 20%, P = 0.029), but the operating time was longer (259 minutes vs. 219 minutes, P = 0.009). The tumour location was significantly lower in the TaTME group, but the distal resection margins were adequate and not different between both groups. The TaTME group had higher incidence rates of prolonged ileus and urinary tract infection, but the other complications were similar between the two groups. The resection margin positivity rates of the TaTME and Lap TME groups were 2.2% and 5.7%, respectively (P = 0.670). At a median follow up of 39 months, no abnormal early recurrence was detected. Conclusion: It is technically feasible and oncologically safe to perform TaTME in a medium-volume colorectal unit. Patients with difficult pelvic anatomy can benefit by reducing the risk of conversion and margin positivity rate.

Gallstones with common bile duct stones is a common condition in Hong Kong. Management still remains a challenge nowadays. Laparoscopic cholecystectomy with intraoperative endoscopic retrograde cholangiopancreatography (ERCP) is a single-stage approach which improves patient comfort and is associated with less post-ERCP pancreatitis. With the new endo-laparoscopic operating theatre in service, the combined endo-laparoscopic approach becomes simple and practical. We report here our two early experiences using this approach.
