Diagnosis and treatment status of perioperative anemia in patients with gastrointestinal neoplasms: a multi-center study in Hubei Province / 中华外科杂志

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Accordion operation for the bone transport in treating tibial bone defect / 中国骨伤

<p><b>OBJECTIVE</b>To discuss clinical outcomes of accordion operation for the Ilizarov technique in treating tibial bone defects.</p><p><b>METHODS</b>From January 2014 to June 2016, 22 patients with tibial bone defects were treated by Ilizarov bone-transport technique, including 19 males and 3 females with an average age of 44.04 years old ranging from 23 to 60 years old;the length of the bone defects before the bone transport was 5 to 11 cm with an average 7.68 cm; Cause of injury invlved traffic accidents in 14 cases, fall injury in 3, smashing injury in 4, high drop injury in 1; 6 cases were on the left and 16 cases were on the right. The patients were divided into two groups: 11 cases in accordion group were treated by "accordion operation" after bone transport was completed;11 cases in control group were treated by the external fixator locked waiting for bone consolidation after bone transport was completed. All patients were followed up for 18 to 36 months with an average time of 27.9 months. There was no statistical significance between two groups, such as sex, age, length of bone defect(>0.05). Analysis of healing time, healing index and other indicators, and Paley's criterion was used to evaluate the healing effect of bone healing and function recovery of the limb.</p><p><b>RESULTS</b>The result of X-ray evaluation was all patients achieved bone healing. In accordion group, the bone healing time was (365±91) days, the bone healing index was (46.2±3.5) d/cm; in control group, the bone healing time was(435±108) days, the bone healing index was (57.8±3.5) d/cm. There was no statistical significance in the bone healing time between the two groups(=1.648, =0.115);There was statistical significance in the bone healing index between the two groups(=7.754, =0.000). At the final follow-up, according to Paley's criterion, the result in accordion group was excellent in 9 cases, good in 2 cases; in control group, excellent in 8 cases, good in 3 cases. Score was not statistically significant(=-0.479, =0.619). Complications involved nail infection (9 cases in accordion group, 10 cases in control group);local traction pain (2 cases in accordion group, 1 case in control group); axial malalignment>10°(4 cases in accordion group, 3 cases in control group);location difference of the junction of bone defects (3 cases in accordion group, 2 cases in control group);Complications were not statistically significant(>0.05).</p><p><b>CONCLUSIONS</b>Accordion operation for the Ilizarov technique in treating tibial bone defects can shorten the treatment time and consolidation time, and improve the healing index.</p>
