[The treatment of esophagojejunal anastomotic stricture after total gastrectomy].

From December 1983 through December 1988, 200 cases of total gastrectomy were performed in Chang Gung Memorial Hospital. The esophagojejunostomy was performed with EEA staplers in 196 cases, and with hand suture in 4 cases. Twelve cases developed anastomotic stricture after the operation. All of these 12 anastomoses were done with EEA 28 mm staplers. Four of the 12 patients received no further treatment either because the symptoms were mild or because of development of carcinomatosis. Six patients received endoscopic YAG laser treatment, only 2 had good results. Four Patients received balloon dilatation, 2 of them had good results, 4 patients received surgical intervention after failure of the balloon dilatation or YAG laser treatment. Of the 4 patients who underwent surgery, the thoracoabdominal approach was used in 3, and a thoracotomy in 1. Three patients received side to side esophagojejunostomy to bypass the stricture site. In the remaining patient, stricture was excised and a new end to end anastomosis was done with hand sutures. All of these 4 patients had good results after the operation. There are many possible mechanisms of the development of anastomotic stricture. Anastomotic leakage, technical error, lack of mucosa-to-mucosa apposition, size of the EEA stapler and tissue ischemia all have been regarded as the possible causes of anastomotic stricture. Once the esophagojejunal anastomosis stricture occurs, treatment should be done to relieve dysphagia. From the results of our patients, endoscopic YAG laser is not a satisfactory treatment for anastomotic stricture.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic resection in 120 patients with hepatocellular carcinoma.

During the 11-year period from 1977 through 1987, hepatic resections were carried out in 120 patients with hepatocellular carcinoma (HCC). Twenty-five had HCCs smaller than 5 cm in diameter. There were 97 male and 23 female patients, with an average age of 51.5 years. Among them, 45.8% had liver cirrhosis and 80.8% were positive for hepatitis B surface antigen. Fourteen with ruptured HCCs underwent hepatic resection to control the intra-abdominal hemorrhage. Operative mortality within one month after surgery was 4.1%. The postoperative course was complicated by pleural effusion in 5.8%, subphrenic abscess in 2.5%, postoperative bleeding in 1.6%, hepatic failure in 1.6%, and bile leakage in 0.8% of the patients. The overall five-year survival rate in this series was 25.9%, while survival for the last five years was better (42.3% vs 11.9% for patients treated between 1977 and 1982). The cumulative survival rate had no relation to tumor rupture or liver cirrhosis. The group of patients with smaller tumors (diameter, less than 5 cm) or without vascular invasion by tumor had better survival.

Intrahepatic stones associated with cholangiocarcinoma.

Twenty cases of cholangiocarcinoma associated with hepatolithiasis were treated surgically. The incidence of cholangiocarcinoma associated with hepatolithiasis was 2.4%. Surgical procedures included common bile duct exploration after intraoperative choledochofiberoscopy in 20, with hepatic resection in nine. Overall survival was 8 months, with a range of 3-40 months. The hepatectomy group seemed to have a better prognosis. Accurate preoperative diagnosis of intrahepatic bile duct carcinoma associated with intrahepatic stones is difficult. All 20 patients in this series had surgery for recurrent cholangitis due to intrahepatic stones. From a retrospective review, it became apparent that early diagnosis can be obtained from the following: 1) detection of a hyperechoic mass in the liver parenchyma during abdominal ultrasonography, 2) a scintigraphic defect near the hilum, 3) filling defects or obliteration of intrahepatic ducts in ERCP or PTC, 4) gross appearance of the liver during surgery revealed a nodular tumor mass or an atrophic, fibrotic liver, and 5) intraoperative choledochoscopic findings which showed an intraluminal tumor or infiltrative lesion.

Surgical treatment for spontaneous rupture of hepatocellular carcinoma.

Twenty-seven patients with spontaneous rupture of hepatocellular carcinoma (HCC) underwent surgical treatment during the past ten years. The indications for emergent laparotomy were hemoperitoneum in 14 and unspecified peritonitis in 13. Twelve were found to have noncirrhotic HCC. The incidence of associated cirrhosis was 55.56 per cent. Surgical procedures included hepatic resection in 14, hepatic arterial ligation in six and packing, suture and electrocauterization in seven. Seven died within one month postoperatively, a surgical mortality rate of 28 per cent. Recently, palliative resection has been used more frequently. The group of patients who underwent resection have a better prognosis.
