Conversion of choledochojejunostomy stents to jejunal feeding tubes for postoperative enteral alimentation.

The problem of protein calorie malnutrition following major gastrointestinal surgery can be treated with central venous or enteric alimentation, with the latter being preferred. The authors describe a simple technique for the conversion of biliary stents placed after pancreaticoduodenal surgery into jejunal feeding tubes when the stenting function is no longer needed. Three illustrative cases are presented. In each case, the procedure took less than 30 min and had no associated morbidity. This technique allows early conversion from central venous to enteric alimentation without the need to create a second surgical enterostomy.

Plasma soluble interleukin-2 receptor levels during and after upper abdominal surgery.

Soluble interleukin-2 (IL-2) receptor (sIL-2R) is reported to be up-regulated in inflammatory disorders. Although sIL-2R may modulate perioperative inflammatory responses, it remains unclear whether upper abdominal surgery affects plasma sIL-2R levels. We evaluated the influence of major abdominal surgery on plasma sIL-2R levels. Ten patients scheduled for upper abdominal surgery received anaesthesia with isoflurane, nitrous oxide, and epidural block. Plasma sIL-2R and IL-6 levels were determined at pre-anaesthesia, 0, 2, and 4 hours during surgery, and on postoperative days 1 (POD1) and 3 (POD3). The plasma levels of sIL-2R decreased significantly and achieved their minimum value at 4 hours (677.0 +/- 125.3 pg/ml, P < 0.01 compared to pre-anaesthesia value; 924.5 +/- 178.8 pg/ml, 95% confidence interval = 122.2-550.4). The plasma sIL-2R levels increased on POD1 (1336.5 +/- 174.0 pg/ml) and POD3 (1629.0 +/- 262.8 pg/ml), and reached a level significantly higher than the baseline (P < 0.05 and P < 0.001, 95% confidence interval = 93.4-730.6 and 402.8-1006.2, respectively). The plasma sIL-2R levels on POD3 significantly correlated with the peak IL-6 levels (r = 0.67, P < 0.05). The plasma sIL-2R levels on POD3 correlated with the amount of intraoperative bleeding (r = 0.66, P < 0.05). In conclusion, we found that major abdominal surgery induces characteristic changes in plasma soluble IL-2 receptor levels.

Sonography accurately detects biliary obstruction in patients with surgically created biliary-enteric anastomosis.

The use of sonography to determine the patency of surgically created biliary-enteric anastomoses has been questioned by authors who favor use of cholescintigraphy and percutaneous transhepatic cholangiography for this purpose. We retrospectively reviewed the sonographic findings in 35 patients with such anastomoses: 16 choledochojejunostomies, 11 choledochoduodenostomies, five intrahepatic cholangiojejunostomies, and three cholecystoenterostomies. The anastomosis was patent in 25 patients, completely obstructed in four, and partially obstructed in six. Five of the 25 patients with patent anastomoses had nonanastomotic complications with biliary stasis and cholangitis. In the 20 patients with patent anastomoses and no complication, sonography showed bile ducts ranging from 2 to 9 mm in diameter filled with bile (six), gas (two), or both (12). No patient with a normally functioning anastomosis had evidence of a dilated bile-filled duct in the upright position. In four patients with complete obstruction of the anastomosis, sonography showed dilated, bile-filled ducts ranging from 6 to 14 mm in diameter proximal to the anastomosis. Sonograms in all six patients with partial obstruction showed both gas and bile in dilated bile ducts with superficial gas-filled ducts and dependent bile-filled ducts creating gas/fluid interfaces, which were persistent in the upright position. The 15 patients with anastomotic obstruction or other complication had confirmatory percutaneous transhepatic cholangiography (nine patients), scintigraphy (five patients), CT (four patients), and surgery (eight patients). Our experience suggests that sonography can be used to accurately assess surgically created biliary-enteric anastomoses for both anastomotic patency and for other complications.

Imaging of the biliary sump syndrome.

Side-to-side choledochoduodenostomy is a safe and effective surgical technique to improve biliary drainage in selected patients. The segment of common bile duct between the anastomosis and the ampulla of Vater may act as a stagnant reservoir or sump. When debris, stones, or infected bile accumulates in the sump, usually because of malfunction of the ampulla of Vater, recurrent abdominal pain or symptoms of cholangitis, pancreatitis, or biliary obstruction may develop. This uncommon (0.14-1.30%) complication is known as the sump syndrome. On imaging studies, diagnostic findings are debris or stone(s) in the common bile duct. Suggestive findings are dilated bile or pancreatic ducts, and changes due to pancreatitis, cholangitis, or liver abscess. Patients with this syndrome frequently have multiple imaging studies before the condition is recognized. The purpose of this essay is to illustrate the imaging findings of this syndrome.

Postoperative changes, complications, and recurrent disease after Whipple's operation: CT features.

Whipple's operation consists of resection of the pancreatic head and duodenum, followed by pancreaticojejunostomy, choledochojejunostomy, and gastrojejunostomy or duodenojejunostomy. Indications include neoplasms of the periampullary region, symptomatic chronic pancreatitis, and, occasionally, trauma CT is useful in diagnosing postoperative complications and in detecting disease recurrence during long-term follow-up. This complex surgical procedure causes alterations of the normal anatomy, which may lead to difficulty interpreting images. Familiarity with the appearance of postoperative changes and common complications and with patterns of disease recurrence is a prerequisite to accurate interpretation of CT scans in these patients.

Modification of reticuloendothelial function by muramyl dipeptide-encapsulated liposomes in jaundiced rats treated with biliary decompression.

Rats with 2 weeks of biliary obstruction, with and without 1 week of concomitant biliary decompression relieving the jaundice, were treated with physiologic saline, free muramyl dipeptide (MDP), placebo liposomes, or liposome-encapsulated MDP. Reticuloendothelial system (RES) function was evaluated by blood clearance of intravenously injected 125I-labelled Escherichia coli. The corrected phagocytic index (alpha) after 1 week of biliary decompression returned to normal levels in animals treated with MDP liposomes, whereas RES function was impaired (P < 0.05) in all other jaundiced and biliary-decompressed groups. In the biliary-decompressed, MDP-liposome-treated group, hepatic uptake of radiolabelled bacteria was significantly higher (P < 0.05) and renal entrapment of bacteria was significantly lower (P < 0.05) than in all other jaundiced and biliary-decompressed groups. We conclude that treatment with MDP liposomes improves the otherwise impaired RES function in rats with biliary obstruction and biliary decompression.

Biliary drainage after laparoscopic choledochotomy.

AIM: Transcystic biliary decompression (TCBD) has been proposed as an alternative to T-tube placement after laparoscopic choledochotomy (LCD). This permits safe primary closure of the choledochotomy and eliminates the complications associated with T-tubes. TCBD tube has been secured by Roeder knots and transfixation, and removed later than 3 wk after surgery. We presented a modified TCBD (mTCBD) method after LCD using the ureteral catheter and the Lapro-Clip (David and Geck, Danbury, Connecticut, USA), and compared it with T-tube drainage. METHODS: Between October 2002 and June 2003, patients with choledocholithiasis undergoing LCD with mTCBD (mTCBD Group, n = 30) were retrospectively compared to those undergoing LCD with T-tube drainage (T-tube Group, n = 52) at a single institution. RESULTS: There were no significant differences in operative time and retained stones between the two groups. Patients in mTCBD group had a significantly decreased average output of bile compared with those in T-tube group (306+/-141 vs 409+/-243 mL/24 h, P = 0.000). Removal of drain tubes in mTCBD group was done significantly earlier than that in T-tube group (median, 5 vs 29 d, P = 0.000). No complication related to drain tubes was found in mTCBD group, and morbidity rate with the T-tube was significantly higher (11.5%), and bile leakage following T-tube removal was 5.8%. CONCLUSION: A modified TCBD after LCD is safe, effective and easy to perform. It may reduce postoperative complications, especially bile leakage.

Intrabiliary rupture: an algorithm in the treatment of controversial complication of hepatic hydatidosis.

AIM: Intrabiliary rupture (IBR) is a common and serious complication of hepatic hydatid cyst. The incidence varies from 1% to 25%. The treatment of IBR is still controversial. We aimed to design an algorithm for the treatment of hepatic hydatidosis with IBR by reviewing our cases. METHODS: Eight cases of IBR were analyzed retrospectively. Patients were evaluated according to age, sex, clinical findings, cyst number and stage, abdominal ultrasonography and CT-scan, surgical methods, complications, results and coincidental diseases. RESULTS: Female/male ratio was 1/7. Mean age was 52.12+/-18.26 years (range 24-69 years). Right upper quadrant pain, flatulence, palpable hepatic mass were symptoms common in all patients. Cholestatic jaundice was found in four cases. In all patients, cyst evacuation and omentoplasty were performed, followed by either choledochoduodenostomy, T-tube drainage, intracavitary suturing of the orifice, two cases in each. Whereas in two patients diagnosed post-operatively percutaneous drainage of biliary collection or ERCP and sphincteroplasty were added. Morbidity and hospital stay were higher in these cases. CONCLUSION: When the diagnosis of IBR can be done pre- or intra-operatively, morbidity decreases. If a biliary fistula is seen post-operatively, endoscopic procedures such as ERCP, sphincteroplasty or nasobiliary drainage can be applied.

Pyogenic liver abscess after choledochoduodenostomy for biliary obstruction caused by autoimmune pancreatitis.

A 68-year-old man underwent cholecystectomy and choledochoduodenostomy for biliary obstruction and nephrectomy for a renal tumor. Based on clinical and histopathologic findings, autoimmune pancreatitis (AIP) was diagnosed. The renal tumor was diagnosed as a renal cell cancer. Steroid therapy was started and thereafter pancreatic inflammation improved. Five years after surgery, the patient was readmitted because of pyrexia in a preshock state. A Klebsiella pneumoniae liver abscess complicated by sepsis was diagnosed. The patient recovered with percutaneous abscess drainage and administration of intravenous antibiotics. Liver abscess recurred 1 mo later but was successfully treated with antibiotics. There has been little information on long-term outcomes of patients with AIP treated with surgery. To our knowledge, this is the second case of liver abscess after surgical treatment of AIP.

Hepatocellular apoptosis after hepatectomy in obstructive jaundice in rats.

AIM: To investigate the hepatocellular apoptosis after hepatectomy in obstructive jaundice and biliary decompression rats. METHODS: After bile duct ligation for 7 days, rats were randomly divided into OB group in which the rats underwent 70% hepatectomy, OB-CD group in which the rats underwent hepatectomy accompanied by choledochoduodenostomy, CD-Hx group in which the rats underwent choledochoduodenostomy and then received 70% hepatectomy on the fifth day after biliary decompression. The control group (Hx group) only underwent hepatectomy. RESULTS: The level of total serum bilirubin and serum enzymes was significantly lower in CD-Hx group than in OB-CD and OB groups on day 1, 3 and 5 after hepatectomy. The apoptotic index was significantly lower in CD-Hx group than in OB-CD and OB groups on day 3 and 5. The oligonucleosomal DNA fragments and Caspase-3 activity were also lower in CD-Hx group than in OB-CD and OB groups 3 days after hepatectomy, without differences between CD-Hx and Hx groups. CONCLUSION: Hepatocellular apoptosis plays vital roles in jaundice rats, and biliary decompression is more effective in treatment of patients with severe jaundice before operation.

Extraskeletal osteosarcoma in the duodenum of a cat.

A three-year-old, male neutered domestic longhair cat was referred for evaluation of icterus, vomiting, and anorexia. Abdominal ultrasonography revealed a proximal duodenal mass obstructing the common bile duct. The mass was surgically resected, and a cholecystoduodenostomy was performed. The histopathological diagnosis was osteosarcoma. Thoracic radiographs showed no evidence of metastasis, and bone scintigraphy revealed no signs of a primary skeletal osteosarcoma. Four months after surgery, the cat had intermittent vomiting, marked weight loss, and died.
