Summary

The operation used for treating cancer in this location of the colon is called right hemicolectomy. Currently the investigators have two methods of minimal access approach to the abdominal cavity in order to complete this operation: 1. Total Laparoscopic right hemicolectomy The operation is completed by laparoscopic instruments using video laparoscopy. At the end of the procedure, a small wound was created for the delivery of bowel and extracorporeal anastomosis. 2. Hand-assisted laparoscopic right Hemicolectomy A 6.5cm incision is used to allow insertion of one of the surgeon's hands into the abdomen. The operation is completed by the surgeon's hand and laparoscopic instruments, using video laparoscopy. These two operations are essentially identical except for the surgical access. Both total laparoscopic and Hand-assisted laparoscopic surgery has been practiced in the United States and Europe for over 10 years. Studies from the United State and Europe have demonstrated the safety and the benefits of both techniques in terms of pain and recovery. In order to find out which one is a better procedure, the investigators are carrying out a clinical trial to compare the two surgical options in their short-term and long term outcomes. The results of this study may have an impact on the care of similar patients in the future.

Detailed description

Under ALL circumstances, the principles in the Declaration of Helsinki MUST be complied One of the colorectal specialists (Dr CC Chung, Dr KK Yau, Dr JCH Wong and Dr. HY S Cheung) in the colorectal team will be informed. Clear explanation of the diagnosis, natural history of the disease, different treatment options, their likely outcomes and potential complications will be given. If the patient opts for surgical treatment, he/ she will be invited to enter the study. Further explanation about the study will then be given. The patient information sheet will be given. The patient will then be allowed with all the time he/she needed for decision. Randomization: By drawing from concealed envelopes into either the "total lap" (Total laparoscopic right hemicolectomy) or the "hand-assisted" (Hand-assisted laparoscopic right hemicolectomy) groups The Operation: 1. Patients were put on a liquid diet the day before operation. All received mechanical bowel preparation the night before surgery, 2. Prophylactic antibiotics with be given: Cefuroxime 1.5gm IVI Metronidazole 500mg IVI on induction 3. Operation should be performed by two of the following surgeons under general anaesthesia: Dr HYS Cheung Dr. JCH Wong Dr CC Chung Dr KK Yau 4. either Total laparoscopic right hemicolectomy or Hand-assisted right hemicolectomy will be performed according to the randomization. Standardized post-operative care: 1. All patients would receive patient control analgesia (PCA) in the form of intravenous bolus morphine in the immediate postoperative period. The dosage and regimen were reviewed by the anaesthetists in-charge, who would stop the PCA according to their usual practice. Thereafter, Pethidine (1mg/kg) was given intramuscularly every 4 hours on demand. In addition, two tablets of dologesic were prescribed orally every 4 hours on demand; 2. Resume diet and off intravenous fluid as tolerated; 3. The pain score was recorded from postoperative day 1 to day 7 4. Date of ambulation, postoperative mortality and pathology were recorded. Discharge Criteria: 1. Ambulatory (or resume the pre-operative motility status) 2. Free from any complications that required inpatient management 3. Had at least one bowel motion 4. Did not require parental analgesia Follow Up Arrangement: 1. They were reviewed by clinical oncologists as outpatients, and adjuvant chemotherapy were selectively offered based on the final histological staging of the disease 2. All patients were followed up in the surgical clinic according to the structured proforma. They were followed up 4-monthly in the first 3 years, and 6-monthly thereafter. CEA would be taken at each visit. CXR and ultrasound abdomen would be analyzed annually. Surveillance colonoscopy would be analyzed every 3 years.
