1.Endoscopic Hemostatic Treatment of Peptic Ulcer Bleeding
The Korean Journal of Helicobacter and Upper Gastrointestinal Research 2018;18(4):235-241
Peptic ulcer bleeding is a common complication of peptic ulcer disease and the most common cause of upper gastrointestinal bleeding. Despite advances in drug usage and endoscopic modalities, no significant improvement is observed in the mortality rate of bleeding ulcers. The purpose of this review is to discuss various endoscopic hemostatic methods to treat peptic ulcer bleeding. Endoscopic hemostatic techniques can be classified into injection, mechanical, electrocoagulation, hemostatic powder, and endoscopic Doppler-guided hemostatic therapies (the last mentioned being a newly developed technique). Endoscopic hemostasis can be performed as mono or combination therapy using the aforementioned methods. Endoscopic hemostasis is the most important treatment for patients with peptic ulcer bleeding. Endoscopists should consider the treatment approach for peptic ulcer bleeding based on patient characteristics, the size and shape of the lesion, the endoscopist's expertise, and the resources and circumstances at each hospital. Follow-up studies are needed to evaluate the efficacy of newly developed hemostatic powder therapy and endoscopic Doppler-guided hemostasis.

OBJECTIVETo investigate the clinical epidemiology change trend of upper gastrointestinal bleeding (UGIB) over the past 15 years.
METHODSConsecutive patients who was diagnosed as continuous UGIB in the endoscopy center of The First Affiliated Hospital of Sun-Yat University during the period from 1 January 1997 to 31 December 1998 and the period from 1 January 2012 to 31 December 2013 were enrolled in this study. Their gender, age, etiology, ulcer classification, endoscopic treatment and hospitalization mortality were compared between two periods.
RESULTSIn periods from 1997 to 1998 and 2012 to 2013, the detection rate of UGIB was 9.99%(928/9 287) and 4.49%(1 092/24 318)(χ=360.089, P=0.000); the percentage of male patients was 73.28%(680/928) and 72.44% (791/1 092) (χ=0.179, P=0.672), and the onset age was (47.3±16.4) years and (51.4±18.2) years (t=9.214, P=0.002) respectively. From 1997 to 1998, the first etiology of UGIB was peptic ulcer bleeding, accounting for 65.2%(605/928)[duodenal ulcer 47.8%(444/928), gastric ulcer 8.3%(77/928), stomal ulcer 2.3%(21/928), compound ulcer 6.8%(63/928)],the second was cancer bleeding(7.0%,65/928), and the third was esophageal and gastric varices bleeding (6.4%,59/928). From 2012 to 2013, peptic ulcer still was the first cause of UGIB, but the ratio obviously decreased to 52.7%(575/1092)(χ=32.467, P=0.000)[duodenal ulcer 31.9%(348/1092), gastric ulcer 9.4%(103/1092), stomal ulcer 2.8%(30/1092), compound ulcer 8.6%(94/1092)]. The decreased ratio of duodenal ulcer bleeding was the main reason (χ=53.724, P=0.000). Esophageal and gastric varices bleeding became the second cause (15.1%,165/1 092, χ=38.976, P=0.000), and cancer was the third cause (9.2%,101/1 092, χ=3.352, P=0.067). The largest increasing amplitude of the onset age was peptic ulcer bleeding [(46.2±16.7) years vs. (51.9±18.9) years, t=-5.548, P=0.000), and the greatest contribution to the amplitude was duodenal ulcer bleeding [(43.4±15.9) years vs. (48.4±19.4) years, t=-3.935, P=0.000], while the onset age of esophageal and gastric varices bleeding [(49.8±14.1) years vs. (48.8±13.9) years, t=0.458, P=0.648] and cancer [(58.4±13.4) years vs. (58.9±16.7) years, t=-0.196, P=0.845] did not change significantly. Compared with the period from 1997 to 1998, the detection rate of high risk peptic ulcer rebleeding (Forrest stage I(a, I(b, II(a and II(b) increased (χ=39.958, P=0.000) in the period from 2012 to 2013. From 1997 to 1998, 54 patients underwent endoscopic treatment, and the achievement ratio of hemostasis was 79.6% (43/54). From 2012 to 2013, 261 patients underwent endoscopic treatment and the achievement ratio of hemostasis was 96.9%(253/261), which was significantly higher (χ=23.287, P=0.000). Compared to the period from 1997 to 1998, more patients with variceal bleeding or non-variceal bleeding received endoscopic treatment in time (39.0% vs. 70.3%, χ=51.930, P=0.000; 3.6% vs. 15.6%, χ=62.292, P=0.000, respectively), and higher ratio of patients staging Forrest stage I(a to II(b also received endoscopic treatment in the period from 2012 to 2013 [27.4%(26/95) vs. 68.5%(111/162), χ=40.739, P=0.000]. More qualified endoscopic hemostatic techniques were used, containing thermocoagulation (0 vs. 15.2%, χ=79.518, P=0.000), hemostatic clip (0 vs. 55.9%, χ=20.879, P=0.000), hemostatic clip combined with thermocoagulation (4.3% vs. 16.4%, χ=5.154, P=0.023), while less single injection was used (87.1% vs. 6.2%, χ=10.420, P=0.001), and single spraying for hemostasis was completely abandoned in the period from 2012 to 2013. The ratio of inpatients undergoing reoperation decreased obviously in the period from 2012 to 2013 [9.3%(86/928) vs. 6.0%(65/1092), χ=7.970, P=0.005], while no significant difference was found in mortality during hospitalization between two periods.
CONCLUSIONCompared with the period from 1997 to1998, the mean onset age of UGIB increased, and the ratio of peptic ulcer bleeding decreased due to the reduction of duodenal ulcer bleeding, the detection rate of high risk peptic ulcer rebleeding increased, the cure rate of endoscopic treatment for UGIB increased, more reasonable and immediate hemostatic methods were used, but overall mortality did not change obviously in the period from 2012 to 2013.

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.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

Cervical ectopic pregnancy is associated with high risk for massive bleeding conditions. Cervical ectopic pregnancy can usually be treated by methotrexate injection or surgery. We present 4 cases of cervical ectopic pregnancy that were treated successfully with different uterine-conserving methods. By comparing our experience of 4 cases managed in different ways, we found that laparoscopic uterine artery occlusion before cervical curettage is more effective method for preventing massive bleeding.

BACKGROUND/AIMS: To evaluate the long-term efficacy and safety of endoscopic injection of N-butyl-2-cyanoacrylate (NBC; Histoacryl) for treatment of bleeding gastric varices. METHODS: We retrospectively analyzed the records of 455 patients with gastric variceal hemorrhage (GVH) who were consecutively treated with NBC from January 2004 to July 2013, with a mean follow-up period of 582 days. The patients' endoscopic findings, initial hemostasis, complications, rebleeding rates, and bleeding-related death rates were reviewed. RESULTS: Hemostasis was achieved initially in 96.9% (441/455) of patients; rebleeding occurred in 35.2% (160/455), and the bleeding-related death rate was 6.8% (31/455) during follow-up. Complications included fever (6.8%), abdominal pain (3.7%), diarrhea (1.3%), spontaneous bacterial peritonitis (0.7%), bacteremia (0.4%), and embolism (0.2%). A red-color sign on concomitant esophageal varices (EVs) (p = 0.002) and previous history of variceal bleeding (p < 0.001) were significant risk factors for rebleeding within 1 year. The Child-Pugh score (p < 0.001), presence of hepatocellular carcinoma (p = 0.001), and failure of initial hemostasis (p < 0.001) were the risk factors most closely associated with bleeding-related death. CONCLUSIONS: This study provides a comprehensive overview of the outcomes and prognostic factors of patients with GVH. The results may help in the selection of effective treatment strategies for patients with GVH.

OBJECTIVE:
This study investigated the effects and Numerical Rating Pain Scale (NRS) of using absorbable shanching satin rb-bFGF prepreg sheet and expansion hemostatic sponge together nasal packing in the control of epistaxis with blood disease, and compared it with traditional vaseline gauze.
METHOD:
Ninety-six blood disease patient with epistaxis were enrolled between January 2009 and February 2011, they were divided into two groups at random, and differently treated with absorbable shanching satin rb-bFGF prepreg sheet and the vaseline gauze nasal packing for haemostasis. Then haemostasis efficacy,the hemorrhage rate after nasal packing removed and host response, such as nasal pain and headache, which evaluated pain degrees against NRS, were all observed.
RESULT:
There was no significant difference between the two groups of the haemostatic effect. But the hemorrhage rate of treatment group was obviously lower than that of the control group after paching,in addition, host responses, such as nasal pain and headache, remarkably better than the control group, the difference had statistical significance.
CONCLUSION
It is indicate that absorbable shanching satin rb-bFGF prepreg sheet presents reliable hemostasis effect, good biocompatibility and compliance; the pain and headache caused by packing are superior to vaseline gauze. Moreover, this method avoids the direct touch of vaseline gauze with nasal mucosal wound, and reduce hemorrhage after packing. Absorbable shanching satin rb-bFGF prepreg sheet and expansion hemostatic sponge together is better to select the nasal packing material for blood disease patient with epistaxis.

PURPOSE: Several risk factors for development of reexpansion pulmonary edema (REPE) after drainage of pneumothoraces have been reported, but the association between the method of thoracostomy and the development of REPE is unknown. The aim of this study was to compare the frequency of REPE after treatment of spontaneous pneumothorax with trocar or hemostat assisted closed thoracostomy. MATERIALS AND METHODS: We performed a prospective, observational study including 173 patients with spontaneous pneumothorax who visited the emergency department from January 2007 to December 2008. In 2007, patients were treated with hemostat-assisted drainage, whereas patients in 2008 were treated with trocar-assisted drainage. The main outcome was the development of REPE, determined by computed tomography of the chest 8 hours after closed thoracostomy. Outcomes in both groups were compared using univariate and multivariate analyses. RESULTS: Ninety-two patients were included, 48 (42 males) of which underwent hemostat-assisted drainage and 44 (41 males) underwent trocar-assisted drainage. The groups were similar in mean age (24+/-10 vs. 26+/-14 respectively). The frequencies of REPE after hemostat- and trocar-assisted drainage were 63% (30 patients) and 86% (38 patients) respectively (p=0.009). In multivariate analysis, trocar-assisted drainage was the major contributing factor for developing REPE (odds ratio=5.7, 95% confidence interval, 1.5-21). Age, gender, size of pneumothorax, symptom duration and laboratory results were similar between the groups. CONCLUSION: Closed thoracostomy using a trocar is associated with an increased risk of REPE compared with hemostat-assisted drainage in patients with spontaneous pneumothorax.
