We present the case of a patient who underwent successful endoscopic nasobiliary drainage (ENBD) for bile leakage resulting from clip displacement of the cystic duct stump sustained during a laparoscopic cholecystectomy (LC). This 69-year-old man was admitted with symptomatic cholecystolithiasis. After LC was performed, intraoperative cholangiography (IOC) revealed no abnormal findings. However, postoperatively, bilious material began to appear from the intraabdominal drain. Subsequent endoscopic retrograde cholangiopancreatography (ERCP) showed bile leakage from the end of the cystic duct stump. ENBD was performed. Cholangiography using the ENBD tube 14 days later failed to show a bile leak. The ENBD was subsequently removed. The patient improved rapidly with no complaints. Bile leakage due to clip displacement from the cystic duct stump is a potential pitfall of LC, especially if IOC is normal. We recommend careful cystic duct ligation, combined with the use of superior quality ligation clips, to prevent this complication. ENBD is a useful technique to prevent bile leakage after this complication.
Hemorrhage complicating simple liver cyst is rare. On imaging studies, the differential diagnosis between intracystic hemorrhage and cystadenocarcinoma of the liver is unreliable, and hepatectomy has been performed for benign liver cyst in this situation. We describe the characteristics of hemorrhage into a liver cyst in a patient who underwent dome resection of the cyst. In our patient, important diagnostic findings included benign cytologic features in a cyst fluid specimen aspirated with ultrasonographic guidance and a fall in hemoglobin and hematocrit, suggestive of hemorrhage. Other informative features were absence of communication between the intrahepatic bile ducts and the cystic liver lesion upon endoscopic retrograde cholangiopancreatography, as well as benign intraoperative frozen-section histology.
Bile duct injuries are a potential complication of laparoscopic cholecystectomy (LC). A patient who underwent successful endoscopic nasobiliary drainage (ENBD) for a bile duct injury sustained during LC is presented. Of particular note, the patient also had Chilaiditi's syndrome. A 59-year-old woman was admitted with symptomatic cholecystolithiasis and Chilaiditi's syndrome. LC was performed. Postoperatively, the patient complained of abdominal discomfort. Laboratory examination revealed cholestasis. Bilious material began spilling from an intraabdominal drain. Subsequent endoscopic retrograde cholangiopancreatography (ERCP) showed bile leakage. ENBD was performed. Repeat ERCP 10 days later failed to show a bile leak or stenosis of the common bile duct. The patient improved rapidly and had no complaints after the procedure. ENBD is a useful endoscopic technique to prevent peritonitis from bile leakage after LC. Chilaiditi's syndrome is not a contraindication for LC.
We conducted a multicenter prospective study to clarify the efficacy and safety of surgery and imatinib for liver oligometastasis of gastrointestinal stromal tumors. Eligible gastrointestinal stromal tumor patients were enrolled in the surgery trial or the imatinib trial. Primary endpoints were recurrence-free survival and progression-free survival, respectively. The trials were prematurely terminated due to amendment of guidelines for adjuvant imatinib therapy and low patient accrual. In the surgery trial, all the six patients showed hepatic recurrence: median recurrence-free survival was 145 days (range: 62-1366 days). Of the five patients receiving salvage imatinib therapy, two showed progressive disease although no death was observed. Of the five patients enrolled in the imatinib trial, one died of pneumonia after progressive disease, and four had not shown progressive disease as of last visit. The results suggest that liver oligometastasis of gastrointestinal stromal tumor may not be controllable by surgery alone and require concomitant imatinib therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
