Outpatient Laparoscopic Cholecystectomy in Hong Kong Chinese – An Outcome Analysis
Laparoscopic cholecystectomy (LC) is now the procedure of choice for symptomatic gallbladder disease. Although many recent studies, mostly from abroad, report that it can be performed safely in the outpatient setting, the experience of outpatient LC in Hong Kong is still limited. This retrospective study evaluated the feasibility, safety and patient acceptance of outpatient LC in Hong Kong Chinese patients.
Patients and Methods: The data of 73 consecutive patients who had undergone outpatient LC between February 2000 and October 2002 in the Day Surgery Centre of Tung Wah Hospital were prospectively collected and reviewed. The selection criteria for patients undergoing outpatient LC included American Society of Anesthesiologists risk classification I or II, age less than 70 years, and the availability of a competent adult to accompany the patient home and look after them for 24 hours. No effort was made to exclude complicated cases. After assessment by the operating surgeon, patients were discharged from the Day Surgery Centre in the afternoon when their clinical condition satisfied pre-defined discharge criteria. All patients were followed up in the Day Surgery Centre in the first and fourth postoperative weeks.
Results: The same-day discharge rate was 88% and the conversion rate was 4%. Six patients (8.2%) with uneventful LC required hospitalization after the procedure. There was no major complication and no unplanned admission. Two patients had port site wound infection requiring hospital admission at the first follow-up. Patient satisfaction was high, pain acceptance was good, and analgesic consumption was minimal. Mild fat intolerance was common in patients postoperatively (> 50%), but this had almost all resolved by postoperative week four. All patients were able to resume their usual daily activities within 2 weeks after surgery.
Conclusions: LC is a safe and feasible outpatient procedure in Hong Kong, with high levels of patient satisfaction. A prospective study with a larger patient population is warranted to verify whether it should be recommended as treatment for gallstone disease in selected patients in future
Anatomical limits in living donor liver transplantation
We review the anatomical limits of living donor liver transplantation. Graft size is the fundamental challenge in partial liver transplantation. Insufficient graft size leads to small-for-size syndrome, graft failure, and graft loss. However, smaller grafts can be used safely with surgical techniques to optimize outflow and modulate inflow, thereby minimizing portal hyperperfusion. Meanwhile, anatomical variations are common in the vascular and biliary systems. These variants pose additional challenges for vascular and biliary reconstruction. Recognition and appropriate management of these variants ensure donor safety and reduce recipient morbidity. The ultimate principle of partial liver transplantation is to ensure a sufficient graft volume with unimpeded outflow and reconstructable vascular and biliary systems. On this basis, the anatomical limits of living donor liver transplantation can be safely expanded
Experience of living donor liver transplantation for hepatocellular carcinoma in the University of Hong Kong Hospital
Aim: To describe the current practise of living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC), including the patient selection criteria, surgical techniques, management of small-for-size syndrome, postoperative complications, and the results of our units, in the Liver Transplant Centre of Queen Mary Hospital, Hong Kong, one of the high-volume centres for LDLT in Asia.Methods: Our centre practises careful selection for HCC patients using the University of California, San Francisco (UCSF) criteria, supplemented by alpha-fetoprotein level and the model for end-stage liver disease score. Slight flexibility is offered to enthusiastic donors and recipients in LDLT while balancing the risks and benefits. We pioneered in using the extended right lobe graft and the novel hepatic venoplasty technique, which lessen the risk of hyperperfusion and small-for-size syndrome with improved overall recipient survival. Data were collected prospectively and presented as the mean values and ranges, or the number of patients in proportion of total patient population.Results: Of our patients, 74.9% met the UCSF criteria, and 64.5% met the Milan criteria. A 5-year overall and disease-free survival rate of 78.9% and 76.3% were achieved.Conclusion: LDLT is an ideal treatment for HCC in Hong Kong with regard to the critical organ shortage and high demand for transplantation. The current surgical techniques and post-transplant surveillance contribute to the positive outcome
Impact of Tumour Biology on Outcomes of Radical Therapy for Hepatocellular Carcinoma Oligo-Recurrence after Liver Transplantation
It is uncertain whether tumour biology affects radical treatment for post-transplant hepatocellular carcinoma (HCC) oligo-recurrence, i.e. recurrence limited in numbers and locations amendable to radical therapy. We conducted a retrospective study on 144 patients with post-transplant HCC recurrence. Early recurrence within one year after transplant (HR 2.53, 95% CI 1.65–3.88, p < 0.001), liver recurrence (HR 1.74, 95% CI 1.12–2.68, p = 0.01) and AFP > 200 ng/mL upon recurrence (HR 1.62, 95% CI 1.04–2.52, p = 0.03) predicted mortality following recurrence. In patients with early recurrence and liver recurrence, radical treatment was associated with improved post-recurrence survival (early recurrence: median 18.2 ± 1.5 vs. 9.2 ± 1.5 months, p < 0.001; liver recurrence: median 28.0 ± 4.5 vs. 11.6 ± 2.0, p < 0.001). In patients with AFP > 200 ng/mL, improvement in survival did not reach statistical significance (median 18.2 ± 6.5 vs. 8.8 ± 2.2 months, p = 0.13). Survival benefits associated with radical therapy were reduced in early recurrence (13.6 vs. 9.0 months) and recurrence with high AFP (15.4 vs. 9.3 months) but were similar among patients with and without liver recurrence (16.9 vs. 16.4 months). They were also diminished in patients with multiple biological risk factors (0 risk factor: 29.0 months; 1 risk factor: 19.7 months; 2–3 risk factors: 3.4 months): The survival benefit following radical therapy was superior in patients with favourable biological recurrence but was also observed in patients with poor tumour biology. Treatment decisions should be individualised considering the oncological benefits, quality of life gain and procedural morbidity
