1.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.

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.

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.
