AbstractBackground: Ten patients with postoperative external biliary fistula treated by endoscopic sphincterotomy are reported. Methods: Nine of these patients were operated for hepatic hydatid disease and one for a liver abscess. Mean daily output of bile through the fistulae which were present for 5–39 days was approximately 500 cc. Results: Treatment was successful in nine patients with closure of the fistulae in 2–15 days (mean, 7 days). No response was obtained in one patient who was reoperated, and an intrahepatic biliary duct was found to be completely eroded by the cyst wall. Conclusions: Endoscopic sphincterotomy should be the first-line treatment for postoperative external biliary fistulae related to hepatic hydatid disease.

Controversies in the laparoscopic treatment of hepatic hydatid disease

Koray Acarli

BACKGROUND Laparoscopic treatment of hydatid disease of the liver can be performed safely in selected patients. METHODS Six hundred and fifty patients were treated for hydatid disease of the liver between 1980 and 2003 at the Hepatopancreatobiliary Surgery Unit of Istanbul Medical Faculty, Istanbul University. Of these, 60 were treated laparoscopically between 1992 and 2000. A special aspirator-grinder apparatus was used for the evacuation of cyst contents. Ninety-two percent of the cysts were at stages I, II or III according to the ultrasonographic classification of Gharbi. RESULTS Conversion to open surgery was necessary in eight patients due to intra-abdominal adhesions or cysts in difficult locations. There was no disease- or procedure-related mortality. Most of the complications were related to cavity infections (13.5%) and external biliary fistulas (11.5%) resulting from communications between the cysts and the biliary tree. There were two recurrences in a follow-up period ranging between 3.5 and 11 years. DISCUSSION Laparoscopic treatment of hydatid disease of the liver is an alternative to open surgery in well-selected patients. Important steps are the evacuation of the cyst contents without spillage, sterilization of the cyst cavity with scolicidal agents and cavity management using classical surgical techniques. Our specially designed aspirator-grinder apparatus was safely used to evacuate the cyst contents without causing any spillage. Knowledge of the relationship of the cyst with the biliary tree is essential in choosing the appropriate patients for the laparoscopic technique. In our experience of 650 cases, the biliary communication rate was as high as 18%; half of these can be detected preoperatively. In the remaining, biliary communications are usually detected during or after surgery. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy are helpful to overcome this problem. As hydatid disease of the liver is a benign and potentially recurrent disease, we advocate the use of conservative techniques in both laparoscopic and open operations.

BACKGROUND The operations with proven effects on survival in Budd-Chiari syndrome are shunt operations and liver transplantation. PATIENTS AND METHODS Between 1993 and 1999 (June), 13 cases of Budd-Chiari syndrome have been treated surgically. Four cases had concomitant thrombosis of the inferior vena cava; the others had marked narrowing of the lumen due to the enlarged caudate lobe. Mesoatrial (n = 12) or mesosuperior vena caval (n = 1) shunts were constructed with ringed polytetrafluoroethylene grafts. RESULTS The median portal pressure fell from 45 (range 32 to 55) to 20 (range 11 to 27) cm H(2)O (P <0.001). Two patients died in the early postoperative period. One patient who did not comply with anticoagulant treatment had a shunt thrombosis in the second postoperative year. The other 10 patients are alive without problems during a median 42 (range 1 to 76) months of follow-up. CONCLUSION Mesoatrial shunt with a ringed polytetrafluoroethylene graft is effective in Budd-Chiari syndrome cases with thrombosis or significant stenosis in the inferior vena cava.

Background: Radical resection is the only potentially curative treatment for hepatic alveolar echinococcosis (AE). Although Turkey is an endemic region, population screening is not performed and early diagnosis is rare. Consequently, surgeons are compelled to explore possibilities such as near-total resection and biliodigestive anastomosis for palliation of jaundice. Methods: Surgery was performed in 32 patients with hepatic AE with the following indications: (1) resection; (2) palliation of jaundice; (3) definite assessment of operability; (4) failure in the management of cavity infection by percutaneous methods. Curative resection (R0 = complete resection of all parasitic mass [n = 9], and R1 = a resection in which a small remnant was left on a vital structure [n = 8]) were performed in 17 patients, intrahepatic cholangiojejunostomy in 7, laparotomy-external drainage in 7, and debulking in 1. Results: Perioperative mortality rates were 2/17, 0/7, 2/7 and 1/1, respectively. Twelve patients in the curative resection group are alive without recurrence/progression of the small remnant during a median follow-up of 59 (range 27–116) months. One patient developed an inoperable recurrence that was treated with albendazole. One patient was lost to follow-up. Long-term albendazole treatment was effective in all R1 patients except a patient who had slow asymptomatic progression. Successful palliation of jaundice was achieved in 5 of the 7 intrahepatic cholangiojejunostomy patients. Conclusions: The results of R1 resection in alveolar hydatid disease are similar to those of R0 resection; a small remnant is successfully controlled by albendazole. In patients with jaundice due to hilar invasion, biliary diversion from segment 3 or 5 is effective for palliation of the jaundice and facilitates albendazole treatment.

Abstract: We describe herein a female patient with non-Hodgkins lymphoma of the liver and present a review of the related literature. The patient was referred with the diagnosis of malignant hemangiopericytoma (with an open biopsy). The physical examination, standard laboratory test results and tumor marker levels were all normal. A nonstandard left lobectomy was performed. Histopathological and immunohistochemical examinations revealed non-Hodgkins lymphoma of B-cell type. The findings of a peripheral blood smear and bone marrow biopsy were normal. There was no other site of involvement based on physical or radiological examinations. These findings established the diagnosis of primary hepatic lymphoma. Fewer than 100 cases have been reported in the world literature. The best treatment results have been obtained by a resection followed by chemotherapy when feasible.

Orhan Bilge; İlgin Özden; Yilmaz Bilsel; Yaman Tekant; Koray Acarli; Aydin Alper; Ali Emre; Orhan Arıoğul

Between 1977 and 1995, 495 patients were operated on for hepatic hydatidosis. Total pericystectomy was performed in 26 patients (closed technique in 21 and open technique in 5). Twenty-one patients had single cysts and 5 had two cysts. The median cyst diameter was 8cm (range; 3–20cm). The requirements for total pericystectomy were: (1) the cyst(s) should be located away from the hepatic veins, large bile ducts, or major branches of the portal vein and hepatic artery and (2) the patient should be fit to undergo a major operation. There was no procedure-related morbidity. One patient developed a biliary fistula that closed after endoscopic sphincterotomy. The median hospital stay was 7 days (range; 3–22 days). The median follow up was 24 months (range; 9–114 months). There was disease recurrence in a non-adjacent segment in 1 patient at 4 years. Pericystectomy is a potentially dangerous operation, but it avoids problems with cavity management and has low rates of biliary fistula, spillage, and recurrence. Its success stems primarily from careful patient selection.

OBJECTIVES We present here the outcomes of our first 500 liver transplants and discuss the lessons learned during this time. MATERIALS AND METHODS We retrospectively analyzed the first 500 consecutive transplants within the listing criteria of the United Network for Organ Sharing, with recipients and donors with minimum 1-year follow-up. Patient survival and donor complications were analyzed for 31 liver transplant recipients with hepatocellular carcinoma beyond the Milan criteria who had transplant performed during the same time. RESULTS Between August 2006 and March 2013, there were 519 liver transplants performed in 500 patients (365 adult, 135 pediatric). There were 394 living-donor and 125 deceased-donor liver transplants. In addition, 31 adult liver transplants were performed in patients with hepatocellular carcinoma beyond Milan criteria (22 living-donor and 9 deceased-donor transplants). The main cause of chronic liver failure was biliary atresia in pediatric patients (30.4%) and chronic hepatitis B infection in adults (35.6%). The complication rate for primary nonfunction was 3.8%, overall biliary complications 24.0% (significantly higher after adult living-donor liver transplant, 30.3%), hepatic artery thrombosis 1.6%, portal vein thrombosis 3.0%, retransplant 3.8%, acute cellular rejection 29.6%, and bacterial infection 39.4%. Overall 1-, 3-, and 5-year patient survival rates in the first 500 consecutive transplants performed on recipients within United Network for Organ Sharing listing criteria were 87.8%, 85.0%, and 78.6%; for hepatocellular carcinoma patients beyond the Milan criteria, survival rates were 71.9%, 52.5%, and 38.2%. CONCLUSIONS In regions without a sufficient number of deceased donors, living-donor liver transplant, with its associated problems, is the only alternative to deceased-donor liver transplant. Liver transplant requires teamwork, with all players working well together for a successful outcome. The important keys to success in liver transplant include decision-making, timing, surgical skills, experience, and close follow-up.

Argininosuccinic Aciduria-A Rare Indication for Liver Transplant: Report of Two Cases.

Yankol Y; Nesimi Mecit; Turan Kanmaz; Koray Acarli; Munci Kalayoglu

Argininosuccinic aciduria is a urea cycle disorder caused by an argininosuccinate lyase enzyme deficiency that ends with nitrogen accumulation as ammonia. Argininosuccinic aciduria patients are at risk for long-term complications including poor neurocognitive outcome, hepatic disease, and systemic hypertension despite strict pharmacologic and dietary therapy. As the liver is the principle site of activity of the urea cycle, it is logical that a liver transplant should be an option, with careful patient selection, even in the absence of cirrhosis. We present 2 pediatric argininosuccinic aciduria patients who underwent a living-donor liver transplant from their mothers. After the liver transplant, the general well-being of the patients and their quality of life improved significantly. Liver transplant should be an option for argininosuccinic aciduria patients to prevent further neurologic deterioration and improve the patients quality of life.

Abstract:  Intraoperative dysrhythmias commonly occur in the surgical management of congenital heart diseases. It may also be seen in other surgical procedures. The initiating factors for an arrhythmia during surgery is usually a transient insult such as hypoxemia, cardiac ischemia, catecholamine excess, electrolyte abnormality and acidosis. CAVB is a life‐threatening dysrhythmia in all ages. We herein report a case of transient CAVB in a 30‐month‐old boy during living‐related liver transplantation for bile duct paucity‐associated liver cirrhosis. Moreover, we discuss the probable etiology and treatment of CAVB in liver transplantation.

Obstruction of a major hepatic vein, or major portal vein, or biliary tree branch causes atrophy of the related hepatic region, and frequently, hypertrophy in the remaining liver—the atrophy-hypertrophy complex (AHC). Whether hydatid cysts can causeAHCis controversial. The records of 370 patients who underwent surgery for hepatic hydatid disease between August 1993 and July 2002 were evaluated retrospectively. Excluding six patients with previous interventions on the liver, AHC had been recorded in the operative notes of 16 patients (4.4%); for all patients, a cyst located in the right hemiliver had caused atrophy of the right hemiliver and compensatory hypertrophy of the left hemiliver. The computed tomography images of seven patients were suitable for volumetric analysis. The median (range) right and left hemiliver volumes were 334 (0-686) ml and 1084 (663-1339) ml, respectively. The median (range) cyst volume was 392 (70–1363) ml. AHC due to Echinococcus granulosus was confirmed by objective volumetric analysis. The presence of AHC should alert the surgeon to two implications. First, pericystectomy may be hazardous due to association with major vascular and biliary structures. Second, in patients with AHC, the hepatoduodenal ligament rotates around its axis; this should be considered to avoid vascular injury if a common bile duct exploration is to be performed.
