Effect of perioperative intestinal probiotics on intestinal flora and immune function in patients with colorectal cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the effect of perioperative application of intestinal probiotics to substitute oral intestinal antimicrobial agents on intestinal flora and immune function in surgical patients with colorectal cancer.</p><p><b>METHODS</b>Sixty patients with colorectal cancer undergoing elective laparoscopic radical surgery were randomized to receive preoperative bowel preparation using oral intestinal antimicrobial agents (n=20) or using oral intestinal probiotics (Jinshuangqi Tablets, 2.0 g, 3 times daily) since the fifth day before the operation and at 24 h after the operation for 7 consecutive days. Upon admission and 7 days after the operation, fecal samples and fasting peripheral venous blood were collected from the patients to examine the intestinal flora and serum levels of interleukin-2 (IL-2), IgA, IgG, and IgM, NK cell activity, T lymphocytes subsets CD3(+), CD4(+), CD8(+) and CD4(+)/CD8(+) ratio.</p><p><b>RESULTS</b>At 7 days after the operation, the patients receiving probiotics showed significantly increased counts of intestinal Bifidobacterium, Lactobacillus, and Enterococcus (P<0.05) and significantly lowered counts of Escherichia coli and Staphylococcus aureus (P<0.05). The serum levels of IL-2, IgA, IgG and IgM as well as CD4(+) cell percentage all increased significantly in probiotics group compared with those in patients with conventional intestinal preparation (P<0.05).</p><p><b>CONCLUSIONS</b>Perioperative application of intestinal probiotics to replace preoperative oral intestinal antimicrobial agents can effectively correct intestinal flora imbalance and improve the immune function of surgical patients with colorectal cancer.</p>

Laparoscopic disc hand assisted laparoscopic splenectomy for patients with ruptured spleen / 中国医师杂志

Objective To investigate the feasibility and clinical efficacy of laparoscopic disc hand assisted laparoscopic splenectomy(LDHALS) for patients with ruptured spleen.Methods LDHALS was performed in 14 patients with ruptured spleen,and among them,8 cases were combined with other visceral trauma.Results All cases were performed successfully by using LDHALS.The median operation time was 70 min(45～100 min).The average hospital stay was 7 days in 6 cases with only spleen trauma and 13.5 days in 8 cases combined with other injuries.No major operative complications and mortality occurred.Conclusion The LDHALS is safe,effective,simple and flexible performed for patients with ruptured spleen.
