OBJECTIVETo explore early diagnosis, treatment and prevention of gastrointestinal (GI) bleeding after cardiac surgery.
METHODSIn the last 13 years, cases complicated with GI bleeding after cardiac surgeries were analyzed retrospectively.
RESULTSFourty-four GI bleeding occurred post-operatively in (6 +/- 3) d. The mortality was 23% (10/44). Thirty-eight were located in upper GI tract, of them 26 underwent conservative therapy while 4 died of other than GI bleeding cause; six underwent laparotomy while 1 and 3 died of septicemia and multi-organ failure respectively; six underwent gastric endoscopic hemostasis by electrocautery or clipping the bleeding vessel while all survived. Six were located in lower GI tract, and 2 of them underwent laparotomy without finding bleeding section and died of multi-organ failure. By multivariable logistic regression analysis, deaths were highly related to the post-operative ventilator-dependence, acute renal insufficiency, intra-aortic balloon pump (IABP) assisting and laparotomy.
CONCLUSIONThe mortality of GI bleeding after cardiac surgeries is very high, early gastrointestinal endoscopic examination and minimally invasive intervention can treat this complication more effectively. GI bleeding must be prevented whenever complicating post-operative ventilator-dependence, acute renal insufficiency, and IABP assisting after cardiac surgery.

BACKGROUND/AIMS: Colonoscopic polypectomy is a valuable procedure for preventing colorectal cancer, but is not without complications. Delayed bleeding after colonoscopic polypectomy is a rare, but serious complication. The aim of this study was to identify risk factors of delayed bleeding after colonoscopic polypectomy. METHODS: A retrospective case-control study was conducted in a single university hospital. Forty cases and 120 controls were included. Data collected included comorbidity, use of antiplatelet agents, size and number of resected polyps, histology and gross morphology of resected polyps, endoscopist's experience, resection method, use of sedation, and use of prophylactic hemostasis. RESULTS: In univariate analysis, size, histology and number of resected polyps, endoscopist's experience, resection method and use of prophylactic hemostasis were significant risk factors for delayed bleeding after colonoscopic polypectomy. In multivariate analysis, risk of delayed bleeding increased by 11.6% for every 1 mm increase in resected polyp diameter (OR, 1.116; 95% CI 1.041-1.198; p=0.002). Number of resected polyps (OR, 1.364; 95% CI, 1.113-1.671; p=0.003) and endoscopist's experience (OR, 6.301; 95% CI, 2.022-19.637; p=0.002) were significant risk factors for delayed bleeding after colonoscopic polypectomy. CONCLUSIONS: Size and numbers of resected polyps, and endoscopist's experience were independent risk factors for delayed bleeding after colonoscopic polypectomy. More caution would be necessary when removing polyps with these factors.

OBJECTIVETo explore the factors of post pancreatoduodenectomy hemorrhage.
METHODSThe clinical data of 263 cases between January 1998 and April 2008 underwent pancreatoduodenectomy were analyzed prospectively.
RESULTSThe overall mortality rate was 4.94% (13/263). Postoperative bleeding occurred in 23 patients (8.75%), with 8 episodes ending fatally (34.8%). The tumor size, Child classification, caput total resection and pancreatic leakage were identified as significant risk factors for post pancreatoduodenectomy hemorrhage by means of univariate analysis. The multivariate Logistic regression analysis revealed that all of the five factors turned out to be the independent risk factors.
CONCLUSIONSThe prevention of these bleeding complications depends in the first place on meticulous hemostatic technique. The pancreatic leakage is also one of the most important factors due to postoperative bleeding. The prophylactic use of somatostatin is not necessary.

4.Complications of transsphenoidal surgery for sellar region: intracranial vessel injury.
Chinese Medical Journal 2009;122(10):1154-1156
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.

PURPOSE: To evaluate the efficacy of intravitreal triamcinolone acetonide (IVT) for the management of postvitrectomy diabetic vitreous hemorrhage. METHODS: The authors conducted a retrospective study of patients with postvitrectomy diabetic vitreous hemorrhage who were administered 4 mg (0.1 cc) of triamcinolone acetonide ophthalmic suspension. Ocular history, adverse events, BCVA, intraocular pressure, external eye examination, slit-lamp biomicroscopy, fundus examination, B-scan ultrasonography, and fundus photography were assessed on day 1, weeks 1, 2, and 4 and months 2 and 3. RESULTS: There were 19 eyes of 18 consecutive patients with mean follow-up after IVT injection of 28 weeks. Of the 19 eyes, 17 eyes (89%) experienced clearing of vitreous hemorrhage within 1 to 5 weeks (mean, 1.7 weeks) with visible triamcinolone precipitates along with blood clot in the inferior aspect of fundus. Of these 17 eyes, 12 eyes (63%) maintained vitreous hemorrhage-free condition at last follow-up with a mean visual acuity of 20/63 (range, 20/320 20/25), whereas 5 (29%) developed recurrent vitreous hemorrhage after clearing of vitreous hemorrhage. Vitreous hemorrhage was not cleared in 2 eyes, which required surgical procedures. CONCLUSIONS: IVT injection may be beneficial for clearing recurrent postvitrectomy Diabetic Vitreous Hemorrhage.

BACKGROUND/AIMS: Second-look endoscopy is performed to check for the possibility of post-endoscopic submucosal dissection (ESD) bleeding and to perform prophylactic hemostasis in most hospitals; however, there is little evidence about the efficacy of second-look endoscopy. We investigated whether second-look endoscopy after ESD is useful in the prevention of post-ESD bleeding. METHODS: A total of 550 lesions with gastric epithelial neoplasms in 502 patients (372 men and 130 women) were treated with ESD between August 18, 2009 and August 18, 2010. After the exclusion of three lesions of post-ESD bleeding within 24 hours, 547 lesions (335 early gastric cancers and 212 gastric adenomas) were included for the final analysis. RESULTS: The occurrence rate of delayed post-ESD bleeding was not significantly different between the second-look group and the no second-look group (1% vs 2.5%, p>0.05). The only predictor of delayed bleeding was tumor size, regardless of second-look endoscopy after ESD (22.8+/-9.87 vs 15.1+/-10.47, p<0.05). There was no difference between the prophylactic hemostasis and nonprophylactic hemostasis groups, including the occurrence rate of delayed bleeding. In the second-look group with prophylactic hemostasis, the hospital stay was more prolonged than in the second-look group without prophylactic hemostasis, but there was no significant difference (p=0.08). CONCLUSIONS: Second-look endoscopy to prevent delayed bleeding after ESD provides no significant medical benefits.

BACKGROUND/AIMS: This stuy evaluated the role of a second-look endoscopy after gastric endoscopic submucosal dissection in patients without signs of bleeding. METHODS: Between March 2011 and March 2012, 407 patients with gastric neoplasms who underwent endoscopic submucosal dissection for 445 lesions were retrospectively reviewed. After the patients had undergone endoscopic submucosal dissection, they were allocated to two groups (with or without second-look endoscopy) according to the following endoscopy. The postoperative bleeding risk of the lesions was not considered when allocating the patients. RESULTS: The delayed postoperative bleeding rates did not differ between the two groups (with vs without second-look endoscopy, 3.0% vs 2.1%; p=0.546). However, a tumor in the upper-third of the stomach (odds ratio [OR], 5.353; 95% confidence interval [CI], 1.075 to 26.650) and specimen size greater than 40 mm (OR, 4.794; 95% CI, 1.307 to 17.588) were both independent risk factors for delayed postoperative bleeding. Additionally, second-look endoscopy was not related to reduced delayed postoperative bleeding. However, delayed postoperative bleeding in the patients who did not undergo a second-look endoscopy occurred significantly earlier than that in patients who underwent a second-look endoscopy (4.5 and 14.0 days, respectively, p=0.022). CONCLUSIONS: A routine second-look endoscopy after gastric endoscopic submucosal dissection is not necessary for all patients.

8.Value of endoscopy application in the management of complications after radical gastrectomy for gastric cancer.
Chinese Journal of Gastrointestinal Surgery 2017;20(2):160-165
Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents. Anastomotic fistula is a serious postoperative complication. In addition to endoscopically placing the small intestine nutrition tube for early enteral nutrition support treatment, endoscopic treatment, including stent, metal clip, OTSC, and Over-stitch suture system, can be chosen to close fistula. For anastomotic obstruction or stricture, endoscopic balloon or probe expansion and stent placement can be chosen. For esophageal anastomotic intractable obstruction after gastroesophageal surgery, radial incision of obstruction by the hook knife or IT knife, a new method named ERI, is a good choice. Bile leakage caused by bile duct injury can be treated by placing the stent or nasal bile duct. In addition, endoscopic methods are widely used as follows: abdominal abscess can be treated by the direct intervention under endoscopy; adhesive ileus can be treated by placing the catheter under the guidance of endoscopy to attract pressure; alkaline reflux gastritis can be rapidly diagnosed by endoscopy; gastric outlet obstruction mainly caused by cancer recurrence can be relieved by metal stent placement and the combination of endoscopy and X-ray can increase success rate; pyloric dysfunction and spasm caused by the vagus nerve injury during proximal gastrectomy can be treated by endoscopic pyloromyotomy, a new method named G-POEM, and the short-term outcomes are significant. Endoscopic submucosal dissection (ESD) allows complete resection of residual gastric precancerous lesions, however it should be performed by the experienced endoscopists.

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical treatment should be performed when necessary. Marginal ulcer after gastric bypass is a kind of peptic ulcer occurring close to small intestine mucosa in the junction point of stomach and jejunum. Ulcer will also occur in the vestige stomach after laparoscopic sleeve gastrectomy, and the occurrence site locates mostly in the gastric antrum incisal margin. Preoperative anti-HP (helicobacter pylorus) therapy and postoperative continuous administration of proton pump inhibitor (PPI) for six months is the main means to prevent and treat marginal ulcer. For patients on whom conservative treatment is invalid, endoscopic repair or surgical repair should be considered. Different surgical procedures will generate different related operative complications. Fully understanding and effectively dealing with the complications of various surgical procedures through multidisciplinary cooperation is a guarantee for successful operation.
