Paraganglioma of the common hepatic duct.

A case of paraganglioma arising in the common hepatic duct is reported. The patient presented with obstructive jaundice. At operation, a soft mass, 5 X 2 X 1.8 cm, was found firmly adherent to the intraluminal surface of the common hepatic duct. At cholecystectomy, exploration of the common hepatic duct was performed and the mass was partially removed. T-tube choledochostomy and operative cholangiography were performed. The final pathological report was paraganglioma of the common hepatic duct. The patient was clinically improved on discharge.

[Somatostatin and choleresis in human beings during the digestive phase].

The effect of somatostatin on human choleresis has been poorly studied. Nearly all present knowledge comes from animal research (dog). In the human being, the effect is known in fasted patients. But no data are available of its action during digestion. In the present study, before removing the choledochostomy T-tube from 73 patients operated on for biliary disease, the bile output (40% of the total choleresis) was measured for 4 hours, at 30 min intervals: during fasting, lunch and after lunch: 1) at fasting (A) 10.5 +/- 2.2 cc; at lunch (B) 18.6 +/- 5.4 cc, and after lunch (C) 16.8 +/- 4.5 cc. These differences were highly significant: A vs B p < 0.0001, and A vs C p < 0.0001. In a second part, 10 of these patients received subcutaneously 0.1 mg of SMS 201-995 (a somatostatin's analogue) 30 min before lunch. In all patients the bile output was significantly reduced: 1) prandial phase (D) 9.6 +/- 2.6 cc, and 2) post-prandial phase (E) 5.1 +/- 2.2 cc. Flow in E was significantly reduced when compared to A. Action of 0.1 mg SMS lasted about 120 min. We conclude that SMS decreases prandial and postprandial choleresis in humans.

[Biliary complications after a liver transplant].

Biliary tract complications are still an important source of morbidity and mortality after liver transplantation. Between March 1988 and September 1991 we performed 111 liver transplants in 109 patients (84 men and 25 women, mean age 44.5 +/- 1.1 year). Biliary tract reconstruction was via a choledocho-choledochostomy (n = 107) or via a Roux limb choledochojejunostomy (n = 4). Ten biliary complications (11.9%) occurred (6 biliary leakage, 3 biliary strictures, 1 biliary cast syndrome). Five patients (5.9%) necessitated operative repair (Roux limb choledochojejunostomy). No death was related to biliary tract complication.

[Experimental biliary reconstruction with a Dacron graft which preserves the function of papilla Vater].

Roux-en-Y cholangiojejunostomy has been widely accepted as a method of biliary reconstruction after resection of the bile duct, however complications such as cholestasis, cholangitis and peptic ulcer attributable to the loss of papillary functions are frequently encountered after this procedure. In this point of view, the author experimentally studied biliobiliary anastomosis with a Dacron vascular graft to preserve normal bile passage through the duodenal papilla. End-to-end choledocho-graft-choledochostomy with a Dacron vascular graft coated with collagen (Hemashield) was carried out in 10 pigs. Out of them three died of complications during the 13th to 26th the POD, and seven were sacrificed 6 weeks after the operation. Two weeks after biliary grafting (n = 3) the grafts were surrounded by thin fibrous tissue and microscopically collagen fibers infiltrating into pores of the graft were noted, however after 6 weeks the grafts were spontaneously detached from the bile duct and floated in bile. The covered fibrous tissue was remained and the anastomotic site was replaced with soft granulation tissue, where infiltration of inflammatory cells were microscopically noted. Caliber of the anastomotic site was not smaller and but for slight elevation of total bile acid level blood biochemistry did not show cholestasis and cholangitis. The papillary function was manometrically well maintained. A Dacron graft shielded by collagen seemed to be inadequate material as a permanent bile duct graft, however granulation tissue after spontaneous removal of the graft may be covered with biliary epithelium, and may heal maintaining normal papillary function.

[Minilaparotomy and "open" laparoscopic surgeries in treatment of patients with cholelithiasis].

The theoretical bases and techniques of an original method for operations on the abdominal organs and peculiarities of the instruments used are discussed. The results of treatment of 374 patients by "open" laparoscopic operations are shown. These were: cholecystectomy with intraoperative cholangiography, choledochotomy, choledocholithotomy, choledochostomy and formation of choledochoduodenostomy. The author claims that the method supplements the conventional laparoscopic and laparotomy method of transabdominal operations. It is suggested that such methods may prove valuable in urology and gynecology.

Acute biliary pancreatitis: sphincter of Oddi and choledochal pressure.

Twenty four patients with biliary pancreatitis were divided into three groups: A (18 subjects underwent surgery on the biliary tract seven days after admission to hospital when acute signs disappeared); B (3 cases were operated two months later), and C (3 patients underwent emergency surgery for acute cholescistitis with simultaneous acute pancreatitis). A cholecistectomy-choledochostomy through a Kehr tube was performed in all patients. Pressure in the main biliary duct (MBD) was measured. Only group A was significant (18 cases). As a control, another group, group D was considered (52 biliary cholecysto-choledochal lithiasis patients without pancreatitis and without transduodenal sphincterotomy). Group A: 1) The mean pressure in MBD on the fourth postoperative day (11 days after onset of pancreatitis) was low (p < 0.0001) in relation to that of group D with Oddi's sphincter (SO) normal; 2) in group A, no significant differences (p-NS) were found in relation to positions: during fasting, 4.4 +/- 4 cm H2O in the upright position, and 5.3 +/- 2 when lying (in group D, 9.9 +/- 4.1 cm H2O upright, and 7.76 +/- 3.6 lying with p = 0.0001), and 3) a slow improvement of pressure was observed and, on the 25th day after operation, it was nearly normal (9 cm H2O upright and 7 cm lying with p < 0.001). Group B: biliary surgery at 2 months; mean pressure in MBD meartly normal. Group C: 1) 4 days after emergency surgery, the pressure in MBF (15 cm H2O upright and 11.7 lying) was higher than in subjects with normal SO, probably due to compression of the distal part of MBD by the inflamed pancreas, and 2) from the 11th day the pressure followed the same evolution as that of group A. In conclusion, in patients with acute biliary pancreatitis, operated on the biliary tract when acute signs disappeared, MBD pressure is low (p < 0.0001) in reference to normal on the fourth post-operatory day (11 days after onset of pancreatitis) and no significant differences were found in relation to positions (upright and lying). The pressure changes are transient (4-5 weeks) and most probably due to the lesions and malfunction of the SO related to pancreatitis.

Choledochoduodenostomy for palliation in unresectable pancreatic cancer.

OBJECTIVE: To determine whether choledochoduodenostomy provides adequate long-term palliation of obstructive jaundice in unresectable pancreatic cancer. DESIGN: Consecutive case series. SETTING: Tertiary referral center. PATIENTS: From 1980 to 1997, 79 consecutive patients (45 men, 34 women; mean age, 67.8 years) with biopsy-proved pancreatic cancer found to be unresectable at operation. INTERVENTION: All patients had resectable disease by preoperative criteria. At exploratory laparotomy, unresectability was determined by the presence of liver or peritoneal metastases, encasement of major vascular structures by tumor, and/or celiac lymph node involvement. Choledochoduodenostomy for biliary bypass was performed in 71 (90%) of 79 patients; Roux-en-Y choledochojejunostomy was performed in the remaining 8 patients. MAIN OUTCOME MEASURES: Resolution of jaundice, duration of hospital stay, mean survival, postoperative complications, and evidence of recurrent biliary obstruction. RESULTS: All patients experienced rapid resolution of jaundice. Average hospital stay was 8.3 days. Mean survival after operation was 13.1 months (range, 2 weeks to 62 months). Postoperative mortality was 3%. There were no biliary or duodenal leaks. Four patients (6%) required hospitalization for gastrointestinal hemorrhage; however, only 1 (1%) was from peptic ulceration. No patient developed recurrent biliary obstruction. CONCLUSIONS: Choledochoduodenostomy provides rapid, long-lasting relief of jaundice, with little morbidity and a low rate of duodenal ulceration, and is the palliative operation of choice when patients are found to have unresectable disease at operation or when stenting procedures fail.

Reconstruction of small and fragile bile ducts without mucosa-to-mucosa anastomosis.

We describe a simple and easy technique for performing choledochojejunostomy without the need to suture the full thickness of the ductal and intestinal walls for patients in whom standard choledochojejunostomy is difficult because the stumps of the residual bile ducts are small and fragile. This technique is useful in partial liver transplantation or after hepatectomy that includes removal of the extrahepatic bile ducts. The procedure involves the placing of external biliary drainage tubes through a Roux-en-Y jejunal loop, positioned transanastomotically, and the use of an external jejunostomy to decompress the loop. The tubes are fixed to the jejunal loop by a purse-string suture and to the duct by simple ligation or a purse-string suture. Anastomosis is performed by suturing the connective tissue and liver parenchyma around the ductal stump to the seromuscular layer of the intestine. Choledochojejunostomy according to this method was performed in 5 cases; the biliary drainage tubes were removed 1 to 4 months after surgery. The only complications were cerebellar infarction and cholangitis, both of which resolved with conservative treatment. We consider that this technique will be helpful as a last-ditch measure when standard choledochojejunostomy, with suturing of the full thickness of the walls of the duct and intestine to secure mucosa-to-mucosa apposition, is impossible because of small and fragile bile ducts.

Pancreatic cystocholedochostomy. First report of a case.

The treatment of choice for most persistent, mature pseudocysts of the pancreas is internal drainage. Cystogastrostomy, cystojejunostomy with a Roux-en-Y loop, and, less frequently, cystoduodenostomy are the surgical techniques most commonly employed to attain effective internal drainage. We present the case of a patient with a pseudocyst arising from the cephalic portion of the pancreatic head and extending into the porta hepatis, causing obstructive jaundice, who was treated by cystocholedochostomy. This simple procedure was performed after an intraoperative cholangiogram showed no ductal obstruction distal to the pseudocyst. A cholecystectomy was also done, and the common bile duct was drained with a T tube. This expeditious procedure, rather than a Roux-en-Y cystojejunostomy, was elected because of the firm adherence of the posterior wall of the common bile duct to the anterior surface of the pseudocyst. The patient had an uncomplicated recovery and has been completely asymptomatic for 2 years. We believe this is the first report of a pancreatic cystocholedochostomy for a pancreatic pseudocyst.

Efferent limb obstruction after pancreaticojejunostomy. A late cause of pancreatitis following Whipple resection.

A previously unreported late complication after Whipple resection of the head of the pancreas was recognized in two patients. Obstruction by adhesions and kinking of the efferent jejunal conduit between the proximal pancreaticojejunostomy and the distal choledochojejunostomy led to repetitive episodes of acute pancreatitis without jaundice. Operative recognition and correction of the obstruction resulted in prevention of further attacks.

Management of bile duct strictures. An evolving strategy.

In an effort to determine the role of interventional radiologic and endoscopic techniques in the management of benign biliary strictures, a retrospective analysis was carried out on 194 consecutive patients with bile duct strictures treated at UCLA between 1955 and 1990. Patients were classified as group 1 (1955 through 1979; n = 138) or group 2 (1980 through 1989; n = 56). Follow-up was for a minimum of 24 months and was in excess of 3 years in 179 patients (92%). Although the incidence of recurrent strictures was similar in the two groups (21% and 23%), the reoperation rate was significantly lower (P less than .02) in group 2 (6%) than in group 1 (21%). Percutaneous transhepatic biliary dilatation, used in 20 patients in group 2, was successful in 13 (93%) of 14 patients with anastomotic strictures and three (50%) of six patients with primary strictures (P less than .05). We conclude that surgical reconstruction remains the standard therapy for patients with primary bile duct strictures. Percutaneous transhepatic biliary dilatation has limited usefulness for these patients, but may be more appropriate for those with anastomotic strictures.

A new procedure for management of extrahepatic portal obstruction. Proximal splenic-left intrahepatic portal shunt.

For management of obstruction of the extrahepatic portal trunk in patients with healthy livers, we designed an end-to-side anastomosis between the proximal splenic vein and the umbilical portion of the left intrahepatic portal vein and performed a splenectomy to relieve portal hypertension, treat hypersplenism, and restore hepatic portal flow. To our knowledge, no other procedure more adeptly restores original hepatic blood flow. Creation of an anastomosis between the coronary vein and umbilical portion of the left intrahepatic portal vein is an alternative method.

A small-bowel segment as a total extrahepatic bile duct replacement.

The effect of a small-bowel segment as a total extrahepatic bile duct replacement, with preservation of the bile passage through the papilla of Vater, was examined in 12 pigs followed up for 420 days. No complications during or after surgery were observed in any of the animals. The laboratory parameters were within normal range during the entire observation period. No anastomotic stenosis was evident on percutaneous transhepatic cholangiography in animals examined 2, 6, or 12 months after surgery. The intrahepatic biliary tract was not dilated. There was obvious peristalsis of the grafted small-bowel toward the papilla of Vater. Autopsies showed that the grafts had healed without any sign of irritation. Histologically, the structure of the graft remained undisturbed. There was a clear distinction between the mucosa of the bile duct and that of the small bowel, with no sign of chronic infection. In the graft as well as in the vascular pedicle, the nerve fibers were intact. Liver biopsy showed no pathologic changes. In light of the results of these experiments, the small-bowel segment appears to be a very promising substitute for the injured extrahepatic biliary duct.

Recurrent cholangitis with and without anastomotic stricture after biliary-enteric bypass.

We recently surgically treated 24 patients incapacitated by recurrent cholangitis after biliary-enteric anastomosis performed for benign disease. Contrary to commonly held dogma, as many as one third of the patients had no evidence of anastomotic stricture indicated by radiologic and operative findings. We identified several other primary and coexistent pathogenetic factors including intrahepatic stricture in 42% of the patients, intrahepatic calculi in 25%, improperly constructed enteric conduits in 13%, and conditions that predispose to bacterial overgrowth in the biliary tree in 17%. Seventy-one percent of the patients had multiple etiologic factors, and of those patients without demonstrable anastomotic stricture, intrahepatic stricture was particularly common. Seventy-one percent remained symptom-free in their first year after operation. The most difficult situation to manage, and the factor responsible for most recurrences after our reoperation, involved intrahepatic stricture. A combined surgical and interventional radiologic approach to complex cases may be useful in selected patients.
