OBJECTIVETo investigate the causes and treatment of postoperative gastrointestinal bleeding after orthotopic liver transplantation (OLT).

METHODSClinical data of 776 patients after OLT between January 2000 and December 2006 were analyzed retrospectively.The experiences in diagnosis and treatment of postoperative gastrointestinal bleeding after OLT were reviewed.

RESULTSGastrointestinal bleeding occurred in 18 patients (2.3%) after OLT, among whom 8 (44.5%) were from peptic ulcer, 3 (16.7%) from gastric and esophageal varices, 3 (16.7%) from gastroduodenitis, 3 (16.7%) from hemobilia, and 1 (5.6%) had diverticular bleeding in the jejunum. These 18 patients with gastrointestinal bleeding were managed with conservative treatment, endoscopic treatment, radiological interventional embolism,or exploratory laparotomy. Five patients died of gastrointestinal bleeding and the gastrointestinal bleeding-related mortality rate was 27.8%. After a mean follow up of 3.5 years, only 1 patient died of recurrence of hepatic cellular carcinoma while others survived disease-free.

CONCLUSIONSGastrointestinal bleeding may occur from different sites after OLT and the mortality is high. Prompt identification of the source of bleeding and correct management are required to improve the prognosis.

We sought to document the clinical performance of the 1st American Academy of Orthopaedic Surgeons (AAOS) guideline on the prevention of symptomatic pulmonary embolism (PE) after total knee arthroplasty (TKA) in Korean patients, in terms of the proportions of the each risk-stratified group, efficacy and safety. Consecutive 328 patients underwent TKA were preoperatively assessed for the risks of PE and bleeding and categorized into 4 groups: 1) standard risk, 2) high risk for PE, 3) high risk for bleeding, and 4) high risks both for PE and bleeding. One of three options was administered according to the groups (aspirin in group 1 or 4; enoxaparin and following aspirin in group 2; antithrombotic stocking in group 3). Incidences of symptomatic deep vein thrombosis (DVT) and PE, and major or minor bleeding complications were evaluated. Majority of the patients (86%) were assessed to be with standard risks both for PE and bleeding. No patient experienced symptomatic DVT or PE and major bleeding. Eleven percent of the patients discontinued chemoprophylaxis because of bleeding-related wound complication. In conclusion, the 1st AAOS guideline functions successfully in Korean patients undergoing TKA in terms of prevention of symptomatic DVT and PE while avoiding major bleeding complications.

OBJECTIVE: To explore the effects of different administration methods of tranexamic acid(TXA) on the perioperative blood loss, hidden blood loss, transfusion rate and adverse reactions in lumbar spinal decompression and fusion. METHODS: Sixty patients who received lumbar spinal canal decompression and fusion from July 2019 to July 2020 were enrolled and divided into observation group and control group, with 30 cases in each group. The observation group was given 2 g TXA orally at 2 hours before operation, control group was given 1 g TXA for 5-10 min before skin incision and 6 hours after operation intravenously. The intraoperative blood loss, postoperative drainage, total blood loss, hidden blood loss, drainage tube removal time, blood transfusion rate, venous thrombosis rate, adverse event rate were recorded respectively. The changes of hemoglobin(Hb) and hematocrit (HCT) were observed before operation and 1, 3 days after operation. RESULTS: Hb and HCT at 1 and 3 days after operation were significantly improved compared with those before operation(P<0.01). However, there was no significant difference between the groups(P>0.05). There were no significant difference in amount of blood loss, postoperative drainage, total blood loss, intraoperative blood loss, hidden blood loss, postoperative drainage time, and blood transfusion rate between two groups (P>0.05). There were no venous thrombosis and adverse events occurred in both groups. CONCLUSION During the perioperative period of lumbar spinal decompression and fusion, oral TXA and intravenous TXA have the same effect in reducing perioperative blood loss and are safe and reliable. It is recommended that oral TXA be used to save medical costs and convenience.

OBJECTIVE: To analyze retrospectively cause, prevention and management of postoperative hemorrhage in surgery of obstructive sleep apnea hypopnea syndrome (OSAHS) in children using plasma-mediated radio-frequency (pmRF) ablation at low temperature. METHOD: Tonsil and adenoid ablation were carried out in 4028 cases diagnosed with OSAHS, using ENTColator lI plasma system of Arthocare company under general anesthesia. RESULT: Postoperative hemorrhage occurred in 37 cases of 4028 cases, among which 1 case occurred after tonsil ablation and other 36 cases occurred after adenoid ablation. Primary hemorrhage was in 7 cases, while secondary hemorrhage in other 30 cases. Cessation of bleeding was achieved by using different methods of hemostasis in all cases. CONCLUSION Tonsil and adenoid ablation were performed by pmRF at low temperature with advantages of less trauma, less bleeding. However, postoperative hemorrhage might occur in a few cases (accounting for 0.92%). Postoperative hemorrhage in these patients was related with preoperatively incomplete control of inflammation of tonsil or adenoid, surgeon's experience, intraoperatively incomplete hemostasis, postoperative crying and restlessness, eating improperly in two weeks after surgery, coagulation factor deficiency. In case of postoperative hemorrhage, good outcome could be achieved by management of compression, pmRF at low temperature, bipolar coagulation.

BACKGROUNDIntracranial vessel injury is a severe complication of transsphenoidal surgery (TSS) for lesions of sellar region. The purpose of this study was to improve recognition of the complication.

METHODSThe clinical data of 400 cases of TSS for sellar region from 1964 to 2004 were reviewed retrospectively. Ten patients with complications of intracranial vessel injury were included in this study, 7 underwent transsphenoidal microsurgery and 3 underwent endoscopic TSS. Subarachnoid hemorrhage (SAH) occurred in 8 cases, hemorrhage of cavernous sinus in one, and post-operative cerebral hemorrhagic infarction caused by thrombosis of injured right internal carotid artery in one. The clinical data of all the patients were analyzed.

RESULTSThe SAH resulted from hemorrhage of residues of tumor in 2 patients and from damaged sellar and arachnoidea in 6 patients. The cause of hemorrhage of anterior intercavernous sinus was malformation of anterior intercavernous sinus. The reason of thrombus of internal carotid artery was manipulation of operation. Three patients died and six patients were cured. One patient lived with hemiplegia.

CONCLUSIONSThe cause of intracranial vessels injury of TSS is complicated. Detailed anatomic knowledge of seller and skilled operation is helpful to reduce the complication.

OBJECTIVETo investigate the causes and the measures of prevention and cure of the dangerous complications (bleeding, pancreatic fistula, biliary fistula and death) after radical pancreatoduodenectomy (RPD) for periampullary malignant tumor.

METHODSThe rate and management of dangerous complications of 156 cases with RPD which were continuous performed by Department of Biliary-Pancreatic Surgery, Affiliated Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2006 and June 2008 were analyzed retrospectively, including 97 males and 59 females with 37 - 79 years old, the mean age was 56.9 years old.

RESULTSAmong the 156 cases with RPD, four patients had massive hemorrhage of gastrointestinal tract due to stress ulcer, two patients had bleeding in the pancreas-intestinal anastomosis after the operation, the rate of postoperative bleeding was 3.9% (6/156). One patient with massive hemorrhage of gastrointestinal tract due to stress ulcer had severe pulmonary infection and ARDS, and died of respiratory failure finally (the overall mortality rate was 0.7%) after ICU for two months. One patients with bleeding in the pancreas-intestinal anastomosis had pancreatic fistula (the rate of pancreatic fistula was 0.7%) 3 days after the second laparotomy to open the jejunum of the pancreas-intestinal anastomosis and make a transfixion of the bleeding points in the stump. Another patient who had the tumor located in the inferior segment of the bile common duct had biliary fistula 11 days after the operation (the rate of biliary fistula was 0.7%). Two patients with fistula had good recovery by expectant treatment of ultrasound-guided puncture and drainage.

CONCLUSIONSPrompt and effective treatment of the complications of bleeding, pancreatic fistula, biliary fistula could maximally decrease the perioperative death rate.

OBJECTIVETo investigate the risk of hidden blood loss about applying rivaroxaban after total hip arthroplasty.

METHODSFrom October 2009 to May 2012,88 patients with femoral head necrosis were treated with primary total hip arthroplasty. All the patients were divided into Rivaroxaban group(44 cases)and control group(44 cases). There were 25 males and 19 females in the Rivaroxaban group, with an average age of (58.48 +/- 15.19) years old; in the control group,24 patients were male and 20 patients were female, with an average age of (61.11 +/- 13.54) years old. The patients in the Rivaroxaban group took Rivaroxaban orally from the first day after operation with a dose of 10 mg each day, and treatment course was 14 days. The patients in the control group took placebo orally at the same time. Dominant blood loss and transfusion were recorded, blood routine examinations were taken before operation and at 3 days after operation. The total blood loss and hidden blood loss were calculated according to the formula.

RESULTSThe mean total blood loss was (1509.56 +/- 325.23) ml and the hidden blood loss was(581.47 +/- 215.01) ml, accounting for (37.88 +/- 10.42)% in the Rivaroxaban group. The mean total blood loss was (1262.30 +/- 397.95) ml and the hidden blood loss was (395.59 +/- 97.33) ml, accounting for (30.62 +/- 0.20)% in the control group. The total blood loss, hidden blood loss and transfusion in the Rivaroxaban group was significantly more than those in control group,b ut there was no significant difference on dominant blood loss between two groups.

CONCLUSIONRivaroxaban increased the overall bleeding risk of total hip arthroplasty, especially hidden bleeding risk, which should be careful used.

OBJECTIVETo evaluate the safety and effectiveness of a modified method of holmium laser enucleation of the prostate (HoLEP)--6-o'clock tunnel HoLEP for the treatment of benign prostate hyperplasia (BPH).

METHODSWe included 112 cases of BPH in this study, 57 treated by 6-o'clock tunnel HoLEP (experimental group) and the other 55 by conventional HoLEP (control group). We compared the operation time, volume of the resected prostatic tissue, intraoperative blood transfusion, volume of bladder irrigation solution, postoperative hemoglobin change, and incidence of urinary incontinence between the two groups.

RESULTSStatistically significant differences were observed between the experimental and control groups in the operation time ([56.01 ± 8.62] min vs [68.65 ± 9.08] min), cases of intraoperative blood transfusion (0 vs 2), volume of bladder irrigation solution ([27.51 ± 3.67] L vs [36.89 ± 6.47] L), postoperative hemoglobin decrease ([10.70 ± 2.50] g/L vs [12.60 ± 3.30] g/L), and cases of postoperative stress-induced urinary incontinence (2 vs 7) (all P <0.05). One-month follow-up revealed smooth urination in both groups of patients but no true urinary incontinence or secondary bleeding in either.

CONCLUSIONModified 6-o'clock tunnel HoLEP can significantly reduce the operation time, bladder irrigation, and intraoperative bleeding, and therefore can be used as a safe and effective option for the treatment of BPH.
