OBJECTIVE:Laparoscopic colectomy has been proved to be both technically and oncologically feasible. However, the approach has been criticized for its procedural complexity and long operative time as a result of the loss of tactile feedback and absence of depth perception. The advent of hand-access devices offered a potential solution to these problems. This randomized controlled trial aims to compare hand-assisted laparoscopic colectomy (HALC) with open colectomy (OC) in the management of right-sided colonic cancer. METHODS:Adult patients with nonmetastatic carcinoma of cancer or ascending colon were recruited. Patients were excluded if they presented with surgical emergencies, had synchronous tumors on work-up, or when the tumor was larger than 6.5 cm in any dimension or preoperative imaging. Recruited patients were randomized to undergo either HALC or OC by the same surgical team. Outcome measures included operative time, blood loss, postoperative pain score and analgesic requirement, length of hospital stay, postoperative complications, as well as disease recurrence and patient survival. RESULTS:Eighty-one patients (HALC = 41, OC = 40) were successfully recruited. The 2 groups were matched for age, gender distribution, body mass index, and comorbidities. No significant difference was observed between the 2 groups in the distribution of tumors and the final histopathological staging. HALC took significantly longer than OC (110 min vs. 97.5 minutes, P = 0.003) but resulted in significantly less blood loss (35 mL vs. 50 mL, P = 0.005). Patients after HALC experienced significantly less pain, required significantly less parenteral and enteral analgesia, recovered faster, and was associated with a shorter length of stay (7 days vs. 9 days, P = 0.004). With median follow-up of 28 to 30 months, no difference was observed in terms of disease recurrence, and the 5-year survival rates remained similar (83% vs. 74%, P = 0.90). CONCLUSION:HALC retained the same short-term benefits of the pure laparoscopic approach. The technique is associated with a slightly increased but acceptable operative time. Aside as a useful adjunct in complex laparoscopic procedures, the hand-assisted laparoscopic technique is also a useful, if not more effective, alternative for patients with right-sided colonic cancer.
