ABSTRACT
Objective To analyze the causes of delayed hemorrhage after colonoscopic treatment in colorectal diseases and the value of second colonoscopic treatment.Methods A retrospective study was conducted on 45 patients with colorectal protrusion lesions (polyps,adenoma,early carcinoma and lipoma) in the Daping hospital of the Third Military medical University from January 2010 to December 2016.The patients suffered from delayed hemorrhage after argon knife coagulation,submucosal resection,submucosal dissection or nylon snares colonoscopic treatment.The mode and clinical outcome of second colonoscopic treatment were summarized by aiming at the reasonsof delayed hemorrhage.Results The predilection sites of delayed hemorrhage were in turn rectum (28.89 ％),sigmoid colon (24.44 ％) and ascending colon (22.22 ％).Adenoma and intraepithelial neoplasia lesions were easier to occurr (88.89 ％).The types of delayed hemorrhage were mainly blood oozing at the lesion resection wound surface as well as blood gushing or ejection.The second colonoscopic treatment modes in these cases were mainly titanium clipping and ring clipping and suturing.Five cases were treated by submucosal injection of adrenaline (1 ∶ 10 000) combined with argon knife coagulation.Thirtyfive cases conducted argon knife coagulationcombined with titanium clipping,3 cases conducted titanium clipping and 2 cases adopted ring clipping hemostasis.Forty-two cases stopped bleeding by once colonoscopic treatment,while 3 cases suffered from re-bleeding,the colonoscopic treatment was performed again,1 case stopped bleeding after using titanium clipping and ring clipping hemostasis again,while other 2 cases were transfered to the surgery department for conducting colectomy.All 43 cases of delayed hemorrhage in this group were cured and discharged after successful hemostasis by colonoscopy.The firm wound treatment after colonoscopic treatment was very important for preventing delayed hemorrhage,and the underlying diseases and postoperative diet management were also the important factors of delayed hemorrhage.Conclusion Timely second colonoscopic examination and treatment can obtain satisfactory clinical effects in the patients sufferring from delayed hemorrhage after colonoscopic treatment.
ABSTRACT
Objective To investigate the risk factors and management of delayed hemorrhage after pancreatoduodenectomy.Methods A retrospective analysis of delayed hemorrhage after the pancreatoduodenectomy in 136 patients was performed.Results In 136 patients,delayed hemorrhage occurred in 19 cases,and the incidence rate was 14.0％ (19/136).10 cases was severe hemorrhage,and sentinel bleeding occurred in 6 cases,also 5 died due to the intra-abdominal infection and MODS.Conclusion Delayed hemorrhage after the pancreatoduodenectomy is closely related to pseudoaneurysm,bleeding due to arteriorrhexis,bleeding of the pancreas' stump.Meanwhile abdominal infection and MODS may be the main reason of the patients' death.Pre-operative preparation,best operation skills and proper post-operation management are the key points to the prevention and treatment of delayed hemorrhage.
ABSTRACT
Objective:To invest the risk factors associated with delayed hemorrhage after pancreaticoduodenectomy occurred.Methods:A retrospective analysis was performed from January 2012 to June 2015 Shengjing hospital 511 cases of patients who accepted pancreaticoduodenectomy.Results:The incidence of PD postoperative delayed hemorrhage was 8.81％ (45/511).Univariate analysis shows:Preoperative bilirubin levels,pancreatic fistula,biliary fistula,postoperative abdominal infection are all the meaningful related factors(P＜0.05).With the application of multivariate logistic regression analysis,pancreatic fistula (OR=2.158) and abdominal infection (OR=3.051) were independent risk factors for postoperative delayed hemorrhages (P＜0.05).Conclusion:Dealing with the postoperative complications of PD like pancreatic fistula,abdominal infection and others,early detection and rapid diagnosis and correct treatment can effectively reduce the incidence of delayed hemorrhage.
ABSTRACT
Microvascular decompression is an effective treatment for hemifacial spasm. Hemorrhage is oneof the complications of microvascular decompression. However, delayed hemorrhage is very rare.Here, we report a case of ipsilateral cerebellar hemorrhage at day seven following microvasculardecompression. A 45-year-old woman presented with left HFS for the previous two years. Diagnostictesting demonstrated the presence of neurosyphilis. Brain magnetic resonance image was unremarkableon presentation. She received microvascular decompression and her hemifacial spasm completelyresolved after surgery. At day seven post-operatively, the patient presented with a sudden onsetheadache. Emergency computed tomography scan showed a cerebellar hemorrhage. A suboccipitalcraniotomy was performed and a cerebellar hematoma was evacuated. The delayed hemorrhage wasattributed to possible microaneurysm from syphilis.
ABSTRACT
OBJECTIVE: The aim of this study was to investigate factors preventing delayed hemorrhage after the loop electrosurgical excisional procedure (LEEP). METHODS: Medical records of patients who underwent LEEP at one university affiliated hospital from October 2013 to January 2015 were reviewed. Patients with or without delayed hemorrhage were classified. LEEP was performed either in an operating room under general anesthesia or in a procedure room with local anesthesia in the outpatient clinic. Delayed hemorrhage was defined as excisional site bleeding occurring between 1 and 30 days after the LEEP requiring intervention such as electro-cauterization, gauze packing, or application of another hemostatic agent. RESULTS: During the study period, 369 patients underwent LEEP. Twenty-three (6.2%) patients with delayed hemorrhage returned to our hospital either to the outpatient clinic or to the emergency unit. A third of the population (103, 27.9%) underwent LEEP in the operating room under general anesthesia without injection of local anesthesia. The remaining patients (266, 72.1%) underwent LEEP with local anesthesia (lidocaine HCl 2% with epinephrine 1:100,000) in the office procedure room. Patients given local anesthesia including epinephrine had significantly lower delayed hemorrhage compared to patients with general anesthesia without injection of local anesthesia (P=0.001). Hemostats, such as fibrin glue or patch, were used for the majority of patients (346, 93.8%) during the procedure. However, using hemostats was not statistically associated with delayed hemorrhage (P=0.163). CONCLUSION: Local anesthesia with the powerful vasoconstrictor epinephrine is effective not only to control perioperative bleeding, but also to prevent delayed hemorrhage after LEEP.

Objective:To investigate the cause, treatment, and prognosis of delayed hemorrhage in patients who underwent radical gastrectomy. Methods:The clinical data of 294 patients who underwent radical gastrectomy in the Second Hospital Affiliated from Nanchang University from January 2015 to October 2015 were retrospectively analyzed. Results:A total of 15 patients suffered from delayed hemorrhage and accounted for 5.1%of the gastric cancer cases in our hospital for the same period of radical gastrectomy. Of the 15 patients, 9 underwent laparoscopic radical gastrectomy and 6 received open radical gastrectomy resection. Large vascular hemorrhage was found in 7 cases. Anastomosis and anastomotic ulcer induced hemorrhage were observed in 3 cases. Duodenal stump rupture induced hemorrhage was detected in 2 cases. Hemorrhage was also observed in some parts in 2 cases. Likewise, hemorrhage occurred in 1 case, but the affected parts were unknown. Of the 11 patients who underwent a second operation, 2 were subjected to digital subtraction angiography (DSA) and transcathete arterial embolization (TAE) to stop hemorrhage. Endoscopic hemostasis was performed to stop hemorrhage in 1 case. Conservative treatment was administered to stop hemorrhage in 1 case. The secondary surgery rate was 73.3%(11/15) with mortality and curative rates of 40%(6/15) and 60%(9/15), respectively. Conclusion:For delayed hemorrhage after D2 of gastric cancer, a second radical surgery and death rates were high. Therefore, patients suffering from hemorrhage should be subjected to comprehensive clinical treatment and positive measures. Major vascular bleeding, anastomotic leakage, anastomotic ulcer, and duodenal stump rupture are relevant risk factors. Anastomotic fistula and celiac artery bleeding complications caused hemorrhage is the leading cause of death. Extensive bleeding and unstable vital signs should be checked. A second operation and abdominal drainage should also be timely conducted to as effective methods. Realistic and conservative treatment can be administered to patients with stable vital signs and low amount of blood loss. Endoscopic hemostasis can be applied to alleviate simple anastomotic ulcer bleeding. DSA can be initially performed to detect unknown bleeding sites. TAE can be subsequently used to treat hemorrhage.
ABSTRACT
Endoscopic resection is currently accepted as a standard therapy for colon polyp because of its safety and efficiency. The indications for endoscopic resection have been expanded to treat mucosal colon cancer and submucosal tumor. The major complications of endoscopic resection are hemorrhage, perforation and post- polypectomy coagulation syndrome. Hemorrhage is the most common complication, and this can occur immediately following colonoscopic polypectomy or it can be delayed after completion of the procedure. Delayed hemorrhage usually occurs within 7 days and this can stop by itself or the hemorrhage can be controlled endoscopically in the majority of patients, with only the unusual and serious cases requiring transfusion, angiography and surgery. We experienced a case of delayed massive hemorrhage with hypotension that required transfusion 12 days after performing endoscopic resection for rectal carcinoid tumor. We report here on this case to provide a good example and to place emphasis on delayed massive hemorrhage after endoscopic resection.

PURPOSE: Delayed hemorrhage rarely happens after a colonoscopic polypectomy, ranging from 0.2 to 1.8% in frequency. Although its occurrence is unpredictable and it may be serious in some cases, scanty data on its causes, characteristics, and effective management exist in Korea. This study was conducted to provide such data, especially data on the characteristics of delayed hemorrhage and its effective management. METHODS: From 1997 to 1999, one endoscopist at Song-Do Colorectal Hospital performed 5236 polypectomies on 2511 patients. Delayed hemorrhage occurred after 9 of those polypectomies, for a bleeding incidence rate of 0.17% (9/5236). The authors reviewed those 9 incidence of delayed hemorrhage, which involved 9 patients and 9 lesions, with emphasis on the characteristics of the bleeding and the treatment. RESULTS: The mean age of the 9 patients was 50 years, and the male-to-female ratio was 8: 1. The sigmoid colon was involved in 4 of those patients (44.4%), and the right-sided colon was involved in another 4 of those patients. Lesions smaller than 11 mm were either sessile or flat-elevated and accounted for 6 of the 9 lesions (66.7%). The remaning lesions, which were larger than 10 mm, were either pedunculated or semipedunculated. Three (3) of the 9 patients (33.3%) experienced bleeding on day 1, the most common bleeding day. Another 5 patients (55.6%) experienced bleeding during the next 4 days (days 2 to 5). The last patient experienced bleeding on day 9, the latest bleeding day. A snare polypectomy had been performed on 7 of the 9 patients (77.8%), and a hot biopsy had been performed on the other 2 (22.2%). All delayed bleeding was treated by using hemoclips; additional epinephrine injection was used in 55.6% of the cases and an additional detachable snare in 22.2%. Rebleeding was noticed the day following the initial treatment of bleeding in one case and was managed by using hemoclips. CONCLUSIONS: The first 5 days after a colonoscopic polypectomy are crucial, and caution is required during the next 5 days. Thorough knowledge about preventing and managing bleeding is essential.

Owing to their rarity and the preferential use of CT scanning in the evaluation of trauma cases, the diagnosis of traumatic aneurysms is usually missed. Because the lesion are mostly false aneurysm resulting from injury to all vascular layer, about 90% of this lesion bleed within first 3 weeks after trauma and one-half of the patients who experience this bleeding die; therefore, early diagnosis and treatment are the most essential. The diagnosis requires a high index of suspicion and subsequent angiography. The diagnosis needs to be entertained in any patient who deteriorates by delayed cerebral hemorrhage in the period after severe closed or penetrating head injury. Angiographically, traumatic aneurysms usually have poorly defined necks, are not usually at bifurcation sites, are irregular shaped, and have delayed filling and emptying of sac. Traumatic aneurysm tend to increase in size, therefore immediate surgical exclusion is recommended. Current alternative treatment of traumatic aneurysms involves occlusion of the main artery through the use of endovascular techniques, with either detachable balloons or GDC. In intolerable case to occlusion test, it need EC-IC bypass surgery before occlusion. Surgery is a treatment of choice for traumatic aneurysms in distal locations. The outcome seems to depend on severity of the initial head injury.
