Long-term results of surgical treatment for intrahepatic stones

One hundred and nineteen patients with intrahepatic stones treated surgically in Nagasaki University Hospital from 1969 to 1984 were reviewed. The patients were divided into four types according to location of the stones and the presence or absence of stenotic lesions and/or localized dilatation of the intrahepatic bile ducts. Types I and II patients were treated with choledocholithotomy or choledochojejunostomy, while type III patients underwent hepatic resection and type IV patients were treated by partial hepatic resection with bilioenteric anastomosis, including extended hepatico-choledochojejunostomy. The majority of operative or early deaths belonged to type IV and residual stones were present in almost all patients. The long-term results for the 88 patients revealed that the rate of improvement was 100 per cent for type I, 87 per cent for type II, 83 per cent for type III and 84 per cent for type IV. In type IV, the most excellent results (92 per cent) were obtained by extended hepaticocholedochojejunostomy, especially with hepatectomy. It is suggested that extended hepaticocholedochojejunostomy with partial hepatic resection is a reasonable procedure for treating patients with type IV intrahepatic stones.     

Mirizzi syndrome and cholecystobiliary fistula: a unifying classification

A new classification of patients with Mirizzi syndrome and cholecystobiliary fistula is presented. Type I lesions are those with external compression of the common bile duct. In type II lesions a cholecystobiliary fistula is present with erosion of less than one-third of the circumference of the bile duct. In type III lesions the fistula involves up to two-thirds of the duct circumference and in type IV lesions there is complete destruction of the bile duct. A total of 219 patients were identified with these lesions from 17,395 patients with benign biliary tract diseases undergoing surgery. The incidence of type I lesions was 11 per cent, type II 41 per cent, type III 44 per cent and type IV 4 per cent. The majority had obstructive jaundice. In type I lesions, cholecystectomy plus choledochostomy is effective. In type II lesions, suture of the fistula with absorbable material or choledochoplasty with the remnant of gallbladder can be performed. In type III lesions suture is not indicated and choledochoplasty is recommended. In type IV lesions, bilioenteric anastomosis is preferred. Operative mortality rate increases according to the severity of the lesion, as does postoperative morbidity. During cholecystectomy, partial resection is recommended in order to extract the stones, visualize the common bile duct and define the type and location of the fistula. T tubes should be placed distal to the fistula.     

Extent of liver resection for hilar cholangiocarcinoma

Background:

The extent of liver resection for hilar cholangiocarcinoma (HC) remains controversial despite extensive studies. The aim of this study was to determine the safety and efficacy of minor and major hepatectomy, selected by predetermined criteria in patients with HC.

Methods:

From 2000 to 2007, 187 patients with HC were studied prospectively; 138 patients underwent resection with curative intent. Minor hepatectomy was performed in 93 patients with Bismuth–Corlette type I, II or III HC without hepatic arterial or portal venous invasion, and major hepatectomy in 45 patients with type III HC with hepatic arterial or portal venous invasion, or type IV HC.

Results:

Overall mortality and morbidity rates were 0 and 29·7 per cent respectively, and the bile leak rate was 1·4 per cent. Actuarial 1‐, 3‐ and 5‐year survival rates were 87, 54 and 34 per cent respectively in the minor liver resection group, and 80, 42 and 27 per cent for major resection (P = 0·300).

Conclusion:

Minor liver resection for HC, selected by predetermined criteria, had good results. Major liver resection, which had a higher operative morbidity rate than minor resection, should be reserved for Bismuth–Corlette type III HC with vascular invasion, or type IV HC.

Colon and rectal carcinoma. Forty years and 1400 cases

One thousand four hundred cases of colorectal carcinoma were treated primarily at the Wake Forest University Medical Center between 1945 and 1985. The surgical approach was constant in all patients without obvious stage IV disease: wide resection, including at least the primary-level and intermediate-level lymph nodes. There were 812 women and 588 men in the series. Sixty-eight per cent of the 1400 cancers occurred in the rectosigmoid, but only 53 per cent of the last 300 cases were in this region. Initial staging showed 560 cases (40%) of local disease, 504 cases (36%) of regional disease, and 336 cases (24%) of distant disease. Cecal, ascending, hepatic, and transverse lesions were most often associated with stage IV disease. Among the 1115 patients with long-term follow-up, 44 per cent with stage I disease, 37 per cent with stage II disease, 24 per cent with stage III disease, and 6 per cent with stage IV disease had survived for 5 years or longer. There were no differences when 5-year survival was correlated with site. This review provided no evidence that wide resection leads to increased long-term survival.     

Surgical management of and long-term survival after adenocarcinoma of the cardia

BACKGROUND: The choice of surgical strategy for patients with adenocarcinoma of the oesophagogastric junction is controversial. This study was performed to analyse the surgical results of a 20-year experience with these lesions. METHODS: From January 1981 to January 2001, 126 patients with adenocarcinoma of the cardia underwent resection in the authors' institution. The treatment of choice was oesophagectomy for type I tumours, and extended gastrectomy for type II and III lesions. Morbidity, mortality and survival were determined retrospectively. RESULTS: Fifty-six patients (44.4 per cent) had type I tumours, 44 (34.9 per cent) type II and 26 (20.6 per cent) type III. Primary resection was performed in 113 patients (89.7 per cent). Oesophagectomy with resection of the proximal stomach was carried out in 65 patients (51.6 per cent) and extended total gastrectomy with transhiatal resection of the distal oesophagus in 61 (48.4 per cent). In-hospital mortality and morbidity rates were 4.8 and 34.1 per cent respectively. The overall 3- and 5-year survival rates were 40.9 and 25.1 per cent respectively, and were not affected by the surgical approach. Survival was significantly associated with R0 resection, pathological node-positive category, postoperative complications and tumour differentiation. CONCLUSION: Postoperative mortality, morbidity and long-term survival did not appear to be affected by surgical approach. Further prospective studies are needed to confirm the equivalence between transthoracic and transabdominal approaches.     

Surgical treatment of primary carcinoma of the gallbladder based on the histologic analysis of 48 surgical specimens.

During the past 5 years, extended cholecystectomy and/or more radical procedures, including pancreatoduodenectomy and extended hepatic lobectomy, were performed on 48 patients with carcinoma of the gallbladder in an attempt to cure the disease. It was retrospectively proven from microscopic analysis of the surgical specimens taken from the 48 patients that 28 patients had received curative resections. The 28 consisted of all 4 patients with stage I carcinoma, all 9 with stage II, 6 of 8 with stage III, and 9 of 27 with stage IV. We reached the following conclusions: (1) extended cholecystectomy with resection of the bile duct in the hepatoduodenal ligament is the optimum procedure for patients with stage I and stage II carcinomas, and (2) for patients with stage III carcinoma, more radical procedures, including pancreatoduodenectomy and/or wider resection of the liver, might result in curative resection of the disease. For some patients with stage IV tumors, such as duodenal invasion or direct invasion of the liver, curative resection may be achieved by pancreatoduodenectomy or extended hepatic lobectomy.     

Ten-year survival rates in breast cancer using combination chemotherapy.

The outcome in 254 patients with all stages of breast cancer treated by combination chemotherapy is presented. All the patients were treated 10 or more years ago. The 10-year survival rate for Stages I and II combined is 60 per cent, in Stage III 19 per cent and in Stage IV 3 per cent. The combined rate in Stages I and II differed markedly according to hormonal status. In premenopausal patients the rate was 84 per cent compared with 42 per cent in postmenopausal patients.     

Some considerations for management of choledochal cysts

BACKGROUND: There are five types of choledochal cysts, which are anomalies that involve intrahepatic or extrahepatic bile ducts, or both. These lesions are found most frequently in patients who are Asian, female, infants but are recognized with increasing frequency in adults. METHODS: We have managed 16 patients with this anomaly. One patient was Asian, and 1 was a child. There were 3 males and 13 females. The mean age was 29 years. There were 9 type I, 1 type II, 1 type III, 4 type IV, and 1 type V cysts. Resection of cysts and hepatico Roux-en-Y jejunostomy were performed in 9 patients for type I cysts. Pancreaticoduodenectomy was performed for a type I and a type IV cyst. The extrahepatic portion of a type IV cyst along with a segment of liver was resected in 1 patient. Operation was terminated on 1 patient with a type IV cyst because of extensive involvement of the intrahepatic ducts. She will undergo liver transplantation. The type II cyst was resected. No surgery was performed on a type III and type V cyst. Four of these patients were previously treated unsuccessfully by internal drainage procedures. RESULTS: There was no mortality. Morbidity was limited to a patient who previously underwent incomplete resection of a cyst and a cyst Roux-Y jejununostomy. No cholangiocarcinoma has been encountered in our patients after a mean follow-up of 5.5 years from the time of initial discovery of the choledochal cyst. CONCLUSIONS: Management of choledochal cysts is successful after their complete removal. Partial cyst resection and internal drainage is less satisfactory because of occasional pancreatitis, cholangitis, and cholangiocarcinoma. Resection of the intrahepatic and intrapancreatic portions of the cysts reduces the risk of cancer even though this risk is low after incomplete cyst excision. Biliary continuity after cyst resection is best established by Roux-Y hepaticojejunostomy.

Gastric cancer: a 25-year review

Between 1957 and 1981, 31,716 cases of gastric cancer were registered in the West Midlands, UK. The age-standardized incidence has shown a decrease from 17.42 per 100,000 population during the first quinquennium to 15.30 per 100,000 in the last. There was an apparent increase in the proportion of proximal lesions with a decrease in the proportion of distal, antral cancers. The stage of disease at diagnosis remained constant with 79 per cent of patients having stage IV disease. Less than 1 per cent presented with stage I disease. As a result, the curative resection rate was 21 per cent. The operative mortality rates for curative partial gastrectomy and total gastrectomy were 13 and 29 per cent respectively. Surgeons undertaking more than nine total gastrectomies annually had an overall mean operative mortality rate of 22 per cent. Overall age-adjusted survival at 5 years was 5 per cent. Survival at 5 years for stage I, II and III disease was 72, 32 and 10 per cent respectively. There was a significant increase in survival time for those treated by curative resection between 1972 and 1981 compared with the previous decade. The implications for the management of gastric cancer are discussed.     

Treatment of carcinoma of the gallbladder in Japan

Clinical records of 2567 patients (1717 female and 850 male) with primary carcinoma of the gallbladder in Japan, during the past 19 years, were collected by questionnaires sent out to the main 100 surgical institutes in Japan. Eighty-seven per cent of the patients were over fifty years of age. Gallstones were found in 58.8% of 1496 patients. About 50% of the patients with gallstones had cholesterol group stones. Of the 2269 patients who underwent surgical interventions, radical operations were performed in 467 patients (20.6%). Of the 467 patients, a correct preoperative diagnosis was made in only 77 patients (16.3%). Patients in Nevin's Stages I and II, whose lesions had been confined to the muscle layer, showed a good survival rate with only simple cholecystectomy or extended cholecystectomy, while the patients in Stages III, IV and V, whose lesions had spread beyond the muscle layer, showed poor results even with more aggressive surgical approaches. The poor prognosis of the lesions in Stages III, IV and V might be due to inappropriate aggressive procedures. For the lesions involving all the layers of the gallbladder wall, radical resection, such as extended cholecystectomy plus pancreatoduodenectomy, or extended right lobectomy plus pancreatoduodenectomy, might be recommended.

Intrahepatic segmental bile duct patterns in hepatolithiasis: a comparative cholangiographic study between Taiwan and Japan

Background/Purpose. We analyzed confluence patterns of intrahepatic segmental bile ducts, seeking to relate hepato-lithiasis to anatomic variation. The comparative study was completed patients with hepatolithiasis in Taiwan and Japan. Methods. Direct cholangiography was performed in 103 hepatolithiasis patients in Taiwan and 77 in Japan. Segmental ducts patterns were classified as type I, normal configuration; type II, triad confluence; type III, posterior segmental duct joining left hepatic duct; or type IV, distal confluence of the right posterior segmental duct. Results. Taiwanese patients had only calcium bilirubinate or black stones, and were mostly female. As overall analysis, types I, II, III, and IV were found in 61, 26, 13, and 3 patients, respectively. In Japanese, types I, II, III, and IV were found in 52, 10, 13, and 2, respectively. There was no difference between the two institutes. Since no patients in Taiwan had cholesterol calculi, Japanese patients were reanalyzed including only 58 patients with calcium bilirubinate or black stones. Differences in those populations remained insignificant. Conclusion. Anatomic variations in segmental ducts apparently do not contribute to pathogenesis of hepatolithiasis.     

Extensive surgery for carcinoma of the gallbladder

BACKGROUND: The purpose of this study was to clarify the efficacy of, and define the indications for, extensive surgery for gallbladder carcinoma. METHODS: Between 1979 and 1994, 116 patients with gallbladder carcinoma underwent operation. Radical resection was performed in 80 patients. RESULTS: In 68 patients with stage III or IV disease, extensive resection including extended right hepatectomy (n = 40), pancreaticoduodenectomy (n = 23) and/or portal vein resection (n = 23) was employed to achieve complete tumour excision. The hospital mortality rate was 18 per cent. The postoperative 3- and 5-year survival rates were 44 and 33 per cent respectively in the patients with stage III disease (n = 9), and 24 and 17 per cent respectively in patients with stage IV (M0) disease (n = 29). In contrast, the postoperative survival rate for the 30 patients with stage IV (M1) disease (7 per cent at 3 years and 3 per cent at 5 years) was worse than that for patients with stage III and stage IV (M0) disease (P = 0.009 and P = 0.062 respectively). CONCLUSION: Radical resection should be undertaken for stage III and stage IV (M0) gallbladder cancer. Although portal vein resection and/or pancreaticoduodenectomy did not contribute to long-term survival, better survival was obtained than that for the unresected patients.     

Reoperative surgery in cholelithiasis

From 1965 to 1980, reoperations for residual or recurrent stones were performed on 78 out of 962 Japanese patients with cholelithiasis. The majority of patients who required reoperation had intrahepatic stones. Most of the causes of reoperation were residual stones due to incomplete removal or the non-detection of intrahepatic stones at the previous surgery. Very careful examination of the intrahepatic biliary trees should be done in patients with biliary tract diseases, because in many, the first operation was done during their youth. To remove the intrahepatic calculi completely, hepatic lobectomy should be considered as a final procedure. The causes of reoperation of common duct stones were residual in 60 per cent and recurrent in 40 per cent. Definitive surgery should be done at the first or at least the second operation to avoid irreversible hepatic disorders which have untoward effects on the prognosis. It is important not only to remove the stones but also to relieve the bile stasis in the biliary tract.     

Surgical Outcome and Prognostic Factors in Intrahepatic Cholangiocarcinoma

BACKGROUND: The clinicopathologic features and surgical outcome of intrahepatic cholangiocarcinoma are not fully understood. METHODS: Fifty-six consecutive patients with intrahepatic cholangiocarcinoma who underwent surgical resection at the National Cancer Center Hospital East between October 1992 and July 2007 were retrospectively analyzed. Intrahepatic cholangiocarcinomas were subdivided into solitary tumors and tumors with intrahepatic metastasis. RESULTS: Complete tumor removal (R0 resection) was performed in 42 patients (75%). The 5-year survival rate for patients with intrahepatic cholangiocarcinoma (n = 56), patients with a solitary tumor (n = 46), and patients with intrahepatic metastasis (n = 10) were 32, 38, and 0%, respectively. There was a significant difference in survival between patients with a solitary tumor and those with intrahepatic metastasis (p < 0.0001). The 5-year survival rate for patients with stage I (n = 3), II (n = 9), III (n = 15), and IV disease (n = 26) was 100, 67, 37, and 0%, respectively. There was a significant difference in survival between stage I and stage IV (p = 0.011), between stage II and stage IV (p = 0.0002), and between stage III and stage IV (p = 0.0015). The most frequent site of recurrence was the liver. Univariate analysis showed that intrahepatic metastasis, portal vein invasion, hepatic duct invasion, lymph node metastasis, perineural invasion, and positive surgical margin (R1) were significantly associated with poor survival. Multivariate analysis confirmed that intrahepatic metastasis was a significant and independent prognostic indicator after surgical resection for intrahepatic cholangiocarcinoma (p = 0.001). No patient with intrahepatic metastasis survived more than 10 months in this study. CONCLUSIONS: Intrahepatic metastasis was the strongest predictor of poor survival in intrahepatic cholangiocarcinoma.     

Is there a Role for Radical Surgery in Advanced Gallbladder Carcinoma?

Forty-four patients with advanced gallbladder carcinoma (18 with stage pT₃ and 26 with stage pT₄ of the Union Internacional Contra la Cancrum classification) were aggressively managed by extended heptatic resection in 33 patients, bile duct resection in 28, pancreaticoduodenectomy in seven, gastrointestinal resection in eleven and portal vein resection and reconstruction in seven. Adjacent organ involvement was classified as follows: type I, hepatic involvement with or without gastrointestinal invasion (Ia, Ib); type II, bile duct involvement with or without gastrointestinal invasion (IIa, IIb); type III, hepatic and bile duct involvement with or without gastrointestinal invasion (IIIa, IIIb); type IV, gastrointestinal involvement without hepatic or bile duct invasion. Fourteen of 15 patients with type I tumours had a curative resection compared with seven of 26 with type III lesions (P< 0.0001). The surgical mortality rate was two of 15 patients with type I tumours, seven of 26 with type III tumours and nine of 44 for the whole group. The long-term survival rate after curative resection was four and two of 23 at 3 and 5 years respectively, significantly better than two and none of 21 at I and 2 years after non-curative resection (P<0.01). The survival rate after curative resection for patients with type I tumours was four and two of 14 at 3 and 5 years respectively, significantly better than for other types (P<0.05). This classification of advanced gallbladder carcinoma according to involvement of adjacent organs might be helpful in planning surgery for this condition; in particular, type I tumours should be treated by a radical surgical procedure to achieve a favourable outcome.     

Role of surgery, its results and complications, in the combined treatment of primary gastric non-Hodgkin lymphoma

During ten years 580 patients have been treated for gastric tumour in our department, 510 of them were operated on. Resection could be performed in 296 cases. 17 resections, 5.7 per cent of all were performed because of primary non-Hodgkin gastric lymphoma. No gastric lymphoma was found among the non-resected patients. The preoperative histological diagnosis was correct only in 8 cases. MALT origin could be proved in 5 patients. Synchronous adenocarcinoma and lymphoma was diagnosed in 2 patients. Staging was decided according to Lugano classification. There were six stage I, four stage II, and seven stage IV patients. 8 subtotal and 9 total gastrectomy was performed, 5 were extended and 2 were combined. R0 resection could be carried out in five stage I, two stage II and in one stage IV patient. We lost 2 patients in the postoperative period. Patients were treated with adjuvant chemotherapy (VEP, CHOP) except for 2 patients with low grade MALT lymphoma. The likelihood of one-year survival is 73 per cent, average two-year survival is 63 per cent. When the tumour is operable by total gastrectomy we suggest to perform splenectomy as well, despite of the fact that some postoperative complications can be related to it. We think it is reasonable to perform palliative resection in cases of locally extended stage IV tumours, which affect the patient's quality of life: to cease the pain, passage troubles, bleeding and to improve the conditions for adjuvant treatment.

Sleeve resection of the bronchus and the pulmonary artery for pulmonary lesions

The tissue preserving resections for non-small-cell bronchial carcinoma can be grouped into three main categories: I. bronchoplastic procedures, II. angioplastic procedures, and III. concomitant broncho- and angioplastic procedures, and into the subgroups, standard and extended sleeve resection. The indications are; elderly patients, impaired respiratory reserve, limited tumour growth, and palliative surgery. The analysis of 229 cases yielded follow-up data in 192. The estimated 5 years survival rate was 34 per cent, 19 per cent and 14 per cent in categories I, II and III, respectively. The decrease in survival was due to a greater tumour burden. The operative mortality rate was 8.9 per cent in category I and 17 per cent in category III, such being comparable with standard or extended pneumonectomy, respectively. Surgical techniques and postoperative complications are discussed. Presented at the 82nd Annual Congress of the Japan Surgical Society, 1982, Chiba, Japan     

Prognostic factors and survival after hepatic resection for hepatocellular carcinoma without cirrhosis

BACKGROUND: Detailed follow-up of patients with chronic hepatitis has resulted in increased diagnosis of hepatocellular carcinoma (HCC) in patients without cirrhosis. Despite numerous studies on hepatic resection, the prognostic factors for intrahepatic recurrence and survival are not well known for patients with HCC without cirrhosis. METHODS: Among 349 patients with HCC treated in the past 13 years, cirrhosis was absent in 126 patients (36 per cent). Curative hepatic resection was carried out in 100 (79 per cent) of these patients. Risk factors for intrahepatic recurrence and prognostic factors for survival were evaluated by univariate and multivariate analyses. RESULTS: Postoperative morbidity and mortality rates were 22 and 3 per cent respectively. The 5- and 10-year disease-free and overall survival rates were 31 and 50 per cent, and 22 and 47 per cent respectively. Blood loss, surgical resection margin, intrahepatic metastasis, portal vein invasion and extent of hepatic resection were independently associated with overall survival. However, the only risk factors for intrahepatic recurrence were portal vein invasion and hepatitis C virus (HCV) infection. The former was related to early recurrence while the latter was related to later recurrence. The 5-year disease-free survival rate was 58 per cent in patients with hepatitis B virus infection while it was 6 per cent in patients with HCV infection (P < 0.001). CONCLUSION: In the treatment of HCC without cirrhosis, major hepatectomy is advocated to prevent early recurrence. Liver transplantation may be required for patients with HCV infection.
