Management of a Bleeding Pseudoaneurysm after Pancreaticoduodenectomy: 27 cases experience in single-center

PURPOSE: Delayed massive hemorrhages from pseudoaneurysm rupture of the peripancreatic large arteries, after pancreaticoduodenectomy, are fatal. We reviewed the clinical course and outcome of bleeding pseudoaneurysms after pancreaticoduodenectomy. METHOD: The medical records of 905 consecutive patients who underwent pancreaticoduodenectomies between October 1994 and February 2007 were reviewed retrospectively. In 27 cases with hemorrhagic complications, pseudoaneurysms were diagnosed as the main cause of bleeding. The clinical characteristics, course, management, and outcomes were reviewed. RESULT: In 27 cases (3.0%) of the 905, the bleeding pseudoaneurysms were diagnosed by angiography, during surgery or clinically. In 11 cases, the hemorrhage was from the pseudoaneurysm on the ligated gastroduodenal artery-stump, in five it was from the right hepatic artery, in four from the proper hepatic artery or common hepatic artery, and two from the right gastric artery. Twelve cases had pancreatic leakage. Sentinel bleedings were observed in 21 cases, there were 11 cases of bleeding from the surgical drains, eight cases from the GI tract, and in two cases from both. In 23 cases, arterial embolization was attempted and 18 cases were successful. Four cases had secondary pseudoaneurysmal bleeding. After embolization at the common or proper hepatic artery, six cases had liver abscess or infarction and there was one case of hepatic failure. CONCLUSION: Delayed massive hemorrhage after pancreaticoduodenectomy should be ruled out to determine whether it is associated with an arterial pseudoaneurysm rupture. Transcatheter arterial embolization is an effective modality for control of the bleeding from an arterial pseudoaneurysm.

Multiple Primary Malignant Tumors in Patients with Gastric Cancer

PURPOSE: Because of an improving gastric cancer detection program and treatment methods, we can expect improved survival of patients with gastric cancer. Given the longer survival times, the chance of an occurrence of multiple primary malignant tumors other than stomach is increased in the same patients. The purpose of this study is to analyze the clinical characteristrics and the survival of patients with gastric cancer and other malignancies. MATENRIALS AND METHODS: A retrospective study of 3669 patients with gastric cancer observed at our department between January 1994 to December 2002 was conducted. Associated tumors were diagnosed using the Warren and Gates criteria, and included tumors that were not considered to be a metastasis, invasion, or recurrence of the gastric cancer. RESULTS: Of all 3669 patients, 2.07% (n=76) had primary tumors other than gastric cancer, 63% of which were synchronous (n=48) and 37% metachronous (n=28). The mean age of the study group was 64.9 (65.5 in males, 61.8 in females), and the male-to-female ratio was 4.8 : 1. The most common cancer associated with gastric cancer was a hepatocellular carcinoma (23.7%), followed by colorectal cancer (17.1%), esophageal cancer (10.5%), breast cancer (6.6%). Of the 45 patients who had undergone a resection, 14 were in stage I, 12 in stage II, 13 in stage III, and 6 in stage IV. No statistically significant differences were found between the synchronous and the metachronous groups with regard to age, sex ratio, differentiation, and stage. The 5-year survival rates of the metachronous and the resected patients were significantly higher than those of the synchronous and the non resected patients, respectively. CONCLUSION: Due to increasing length of the follow-up period for patients with gastric cancer, another malignancy may develop in other organs. Therefore, physicians should pay attention to detect other cancers early in these patients, and a surgical resection is recommended as the treatment of choice in the management of multiple primary cancer associated with gastric cancer.

Comparison of Clinical Characteristics between Primary Closure of Common Bile Duct and T-tube Drainage after Choledochotomy / 한국간담췌외과학회지

BACKGROUND/AIMS: In the management of choledocholithiasis, T-tube drainage was the most common treatment modality after common bile duct (CBD) exploration. However, the T-tube drainage has several problems and risk of complications such as abdominal discomfort, long duration of drainage, or bile leakage. We evaluated the effectiveness of primary closure of CBD after choledochotomy and the possibility of substitution for T-tube drainage. METHODS: Seventy six patients with choledocholithiasis who had undergone CBD exploration were enrolled in this study from January 1999 to March 2001. 20 patients among them had undergone primary closure of CBD with preoperative endoscopic nasobiliary drainage (ENBD) or percutaneous transhepatic biliary drainage (PTBD) in situ after exploration (primary closure group), 56 patients had undergone T-tube drainage (T-tube group). We compared the clinical characteristics and outcome between two groups. RESULTS: There was no difference in postoperative complication (19.6% vs. 20%), the mean amount of biliary drainage (326 ml/day vs. 320 ml/day) and the duration of hospitalization (11.6 day vs. 9.2 days) between the both groups. The duration of biliary drainage was significantly longer in the T-tube group (45.3 days) than in the primary closure group (9.2 days; p<0.01). The rate of remnant stone was higher in the T-tube group (32.1%) than the primary closure group (20%), there was not statistically significant. CONCLUSION: The primary closure of CBD with the preoperative biliary drainage was relatively safe and resulted in no difference of clinical outcome. Furthermore, this method induced going back early to normal life. These result suggest that the primary closure of CBD may be a feasible technique after choledochotomy when the patients are selected by specialized indications.
