ABSTRACT
Purpose@#We report our experience in the use of transanal minimally invasive surgery (TAMIS) and the feasibility and safety of this surgical technique in operating for various rectal diseases that require a transanal approach. @*Methods@#Between 2013 and 2019, 30 patients underwent TAMIS for a rectal lesion at Seoul National University Boramae Medical Center. The clinical data including age, gender, body mass index, tumour size, distance from the anal verge, diagnosis, operation time, postoperative complications, duration of hospital stay, and post-operative margin status were obtained retrospectively from the electronic medical records. @*Results@#The mean operation time was 52.1±33.5 and the mean duration of hospital stay after surgery was 4.3±4.2 days. Most of the patients had undergone TAMIS for neuroendocrine tumor (NET) (60%) followed by an adenoma (16.7%) and rectal cancer (13.3%). 4 patients (13.3%) had minor complications after TAMIS. 2 patients (50%) had complained of diarrhea, 1 patient (25%) complained of fecal incontinence and 1 patient (25%) been diagnosed fluid in the operation bed. @*Conclusion@#TAMIS is a useful method for local excision of rectal lesion located in mid to upper rectum as well as other rectal pathologies that require a transanal approach.
ABSTRACT
PURPOSE: Early enteral feeding is recommended in cases of critical illness. However, it is unclear whether this recommendation is of most benefit to extremely ill patients. From our experiences, our authors believed that early enteral nutrition can lead to better prognosis of ICU patients. We aim to clarify the efficacy of early enteral feeding. METHODS: Eighty six critically ill patients were enrolled and grouped as "Early enteral feeding (EF)" and "Delayed enteral feeding (DF)" for this cross-sectional, prospective randomized observational study. To reduce the selection bias, we compare our groups to 20~39% (group A) TBSA (total body surface area, and 40~59% (group B) TBSA burned. BMI (body mass index), length of ICU stay, length of hospital stay, hospital mortality, serum prealbumin, serum transfferin and lymphocyte count data were collected over 28 days. RESULTS: There were no statistical differences in measured outcomes between early and late feeding groups. In serologic test; prealbumin, transferrin and lymphocyte, there is also no statistical difference except 2nd, 4th week of lymphocyte. EF group has higher lymphocyte than DF group. In the group A, however, prealbumin and transferrin was high in EF group during the whole 4 weeks of study. Comparing the ICU stay and hospital mortality, there was also no statistical significance. CONCLUSION: In this study, there is no significant association between hospital outcomes and timing of enteral feeding initiation. More active trials and many-sided studies will be needed to maximize the effect of early enteral nutritional support as a method to improve treatment for major burned patients.
