2.The rat choledochojejunostomy model for microsurgical training.
Annals of Surgical Treatment and Research 2016;90(5):246-249
PURPOSE: The feasibility of a rat choledochojejunostomy (CJ) training model was investigated, as an introductory model to microsurgery for general surgeons. METHODS: Roux-en-Y CJ was performed on 20 rats. Interrupted 10-0 prolene sutures were used to perform CJ. The animals were observed for 7 days and sacrificed and examined. RESULTS: The rats were divided into 2 groups of 10 based on surgical order. The CJ time showed a significant decrease from 36.2 ± 5.6 minutes in group 1 to 29.4 ± 5.7 minutes in group 2 (P = 0.015). The bile leakage rate was 40% in group 1 and 10% in group 2. The survival time was 5.4 ± 2.2 days in group 1 and 7 days in group 2 (P = 0.049). CONCLUSION: The rat CJ training model is a feasible introductory model for general surgeons with no previous experience in microsurgery.

Postoperative biliary stricture is a relatively rare but serious complication of biliary surgery. Although Rouxen-Y hepaticojejunostomy or choledochojejunostomy are well-established and fundamental therapeutic approaches, their postoperative morbidity and mortality rates have been reported to be up to 33% and 13%, respectively. Recent studies suggest that percutaneous transhepatic intervention is an effective and less invasive therapeutic modality compared with traditional surgical treatment. Compared with fluoroscopic intervention, percutaneous with cholangioscopy may be more useful in biliary strictures, as it can provide visual information regarding the stricture site. We recently experienced two cases complete membranous occlusion of the bilioenteric anastomosis and successfully treated both patients using percutaneous transhepatic cholangioscopy.

BACKGROUNDIt is difficult and time-consuming for carrying out conventional hand-sewn bilioenteric anastomosis, especially for small bile duct anastomosis and laparoscopic procedure. In order to simplify it, we have developed a novel procedure of sutureless bilioenteric anastomosis with an intraluminal degradable stent. This study aimed to evaluate the feasibility and safety of this technique with cholangioduodenostomy in dog model.
METHODSA patent intraluminal degradable stent tube for sutureless choledochoduodenostomy in dog model was made with polylactic acid in diameter of 3 mm or 4 mm. Thirty-eight dogs were randomly divided into to a stent group (SG, n = 20) and a control group (CG, n = 18). Dogs in the SG underwent sutureless choledochoduodenostomy with intraluminal stent, while the CG underwent conventional choledochoduodenostomy (single layer discontinuous anastomosis with absorbable suture). Dogs of each group were divided into 4 subgroups according to time of death (1, 3, 6, and 12 months postoperatively) to evaluate the healing of anastomosis. Operation time, intraoperative tolerance pressure of anastomosis, rate of postoperative bile leakage, bursting pressure of anastomosis were compared between the two groups. Anastomosis tissue was observed afterwards by pathology evaluation, hydroxyproline content, serum bilirubin, liver enzyme level and magnetic resonance cholangio-pancreatography (MRCP) to assess the stricture.
RESULTSAll procedures were completed successfully. The surgical time of the SG was significantly less than the CG (SG: (19.2 ± 4.3) minutes, vs. CG: (29.2 ± 7.1) minutes, P = 0.000). One bile leakage was occurred in either group. No significant difference of intraoperative tolerance pressure of anastomosis, rate of bile leakage and postoperative bursting pressure of anastomosis, anastomotic stricture, hydroxyproline content, serum bilirubin and liver enzyme level was found between the two groups. MRCP showed no anastomosis stricture and obstruction during months of follow-up.
CONCLUSIONThe technique of sutureless choledochoduodenostomy with a degradable intraluminal stent is feasible and a safe procedure in this dog model.

5.In vivo porcine training model for laparoscopic Roux-en-Y choledochojejunostomy.
Annals of Surgical Treatment and Research 2015;88(6):306-310
PURPOSE: The purpose of this study was to develop a porcine training model for laparoscopic choledochojejunostomy (CJ) that can act as a bridge between simulation models and actual surgery for novice surgeons. The feasibility of this model was evaluated. METHODS: Laparoscopic CJ using intracorporeal sutures was performed on ten animals by a surgical fellow with no experience in human laparoscopic CJ. A single layer of running sutures was placed in the posterior and anterior layers. Jejunojejunostomy was performed using a linear stapler, and the jejunal opening was closed using absorbable unidirectional sutures (V-Loc 180). RESULTS: The average operation time was 131.3 +/- 36.4 minutes, and the CJ time was 57.5 +/- 18.4 minutes. Both the operation time and CJ time showed a steady decrease with an increasing number of cases. The average diameter of the CBD was 6.4 +/- 0.8 mm. Of a total of ten animals, eight were sacrificed after the procedure. In two animals, a survival model was evaluated. Both pigs recovered completely and survived for two weeks, after which both animals were sacrificed. None of the animals exhibited any signs of bile leakage or anastomosis site stricture. CONCLUSION: The porcine training model introduced in this paper is an adequate model for practicing laparoscopic CJ. Human tissue simulation is excellent.

Sump syndrome is a rare late complication of choledochoenteric anastomosis, and this caused by the accumulation of food debris, choledocholithiasis, bile sludge and cholesterol crystals in the distal common bile duct. This syndrome is characterized by symptoms such as abdominal pain and fever. The treatment modality for this syndrome has been surgery in the past. However, endoscopic treatment such as endoscopic sphinterotomy is currently regarded as the primary therapeutic approach for this condition. We experienced a patient with a history of choledochoduodenostomy and who developed sump syndrome as a complication of the surgery. Endoscopic sphinterotomy was performed for treatment, but this only produced the recurrence of the disease. The recurrent sump syndrome was eventually successfully controlled by performing endoscopic papillary balloon dilatation.

Patients with pancreatic cancer frequently suffer from both biliary and duodenal obstruction. For such patients, both biliary and duodenal self-expandable metal stent placement is necessary to palliate their symptoms, but it was difficult to cross two metal stents. Recently, endoscopic ultrasonography-guided choledochoduodenostomy (EUS-CDS) was reported to be effective for patients with an inaccessible papilla. We report two cases of pancreatic cancer with both biliary and duodenal obstructions treated successfully with simultaneous duodenal metal stent placement and EUS-CDS. The first case was a 74-year-old man with pancreatic cancer. Duodenoscopy revealed that papilla had been invaded with tumor and duodenography showed severe stenosis in the horizontal portion. After a duodenal uncovered metal stent was placed across the duodenal stricture, EUS-CDS was performed. The second case was a 63-year-old man who previously had a covered metal stent placed for malignant biliary obstruction. After removing the previously placed metal stent, EUS-CDS was performed. Then, a duodenal covered metal stent was placed across the duodenal stenosis. Both patients could tolerate a regular diet and did not suffer from stent occlusion. EUS-CDS combined with duodenal metal stent placement may be an ideal treatment strategy in patients with pancreatic cancer with both duodenal and biliary malignant obstruction.

BACKGROUND/AIMS: The long-term results of Roux-en-Y procedure as a treatment for choledochal cyst or cholelithiasis were compared and analyzed. METHODS: A retrospective analysis was carried out for 70 patients (38 type 1 or type 4A choledochal cysts, 33 cholelithiasis) with ages ranging from 17 to 74 years who had undergone hepaticojejunostomy or choledochojejunostomy in a Roux-en-Y manner, with or without hepatectomy. RESULTS: Late complications related to the surgical procedure include cholangitis, recurrent stone, malignancy, abscess, and peptic ulcer disease. The late complication rate was 37.8% in the choledochal cyst group, and 27.3% in the cholelithiasis group. Cholangitis were found in 8.1% of the choledochal cyst group, and in 12.1% of the cholelithiasis group. Recurrent stones were found in 10.8% and 18.2%, respectively. A malignant tumor was found in each group, and both of them were not resectable. Peptic ulcers or erosions were found in 5 patients (13.5%) of the choledochal cyst group, but no one in the cholelithiasis group (p=0.056). CONCLUSION: Late complications after Roux-en-Y procedure in choledochal cyst or cholelithiasis are not uncommon and relatively serious. Long-term follow-up for the patients is mandatory, with attention being given to not only biliary symptoms, but also symptoms related to peptic ulcer disease.

Choledochal cyst has only rarely been encountered in association with pregnancy. The clinical manifestations are nonspecific and variable that makes it difficult to differentiate from physiologic changes in pregnancy. Consequently, diagnosis is often delayed until patients present with life-threatening complications. During pregnancy, symptoms of choledochal cyst may be developed by hormonal changes and the enlarged uterus. Because of the risk of fetal mortality and maternal morbidity, definitive surgical treatment should be delayed and step-by-step management should be carefully implemented to avoid complication until delivery. Herein, we report a case of enlarged, symptomatic choledochal cyst that developed in a 26-year-old pregnant woman. The temporal relationship between pregnancy and symptom development, as well as the biliary sludge formation in the enlarged cyst, suggest that the choledochal cyst was influenced by pregnancy. In order to buy time for fetal maturation, endoscopic ultrasonography-guided choledochoduodenostomy was performed for biliary decompression as a bridge to surgical excision.

PURPOSE: After performing pylous-preserving pancreaticoduodenectomy, there are several methods of performing pancreaticojejunostomy for preventing pancreatic leakage. The purpose of this study was to compare the results of two methods of jejunal anastomosis after pancreaticojejunostomy. METHODS: We retrospectively evaluated the clinical results of 49 patients who had received pancreaticojejunostomy for pylous-preserving pancreaticoduodenectomy. One method is the Billroth-I type, that is, choledochojejunostomy and pancreaticojejunostomy after anastomosis of one jejunum loop to the duodenum. The other method is the Roux-En-Y (R-Y) type. Choledochojejunostomy and pancreaticojejunostomy are done with an isolated jejunum loop. Then gastrojejunostomy is fashioned between the stomach and the distal jejunal segment. Finally, the end-to-side jejunojejunostomy is created. RESULTS: The Billroth-I type was used in 17 patients and the R-Y type was used in 32 patients. The median operation time was 397 min and 431 min, respectively. The median postoperative hospital day was 27.6 days and 22.1 days, respectively. The postoperative complications were 10 cases in 17 patients (58.8%) and 11 cases in 32 patients (34.4%), respectively. Leakage of the pancreaticojejunostomy was the most common complication in each group (23.5% and 15.6%, respectively). Most complications required no need surgical intervention. But two cases of Billroth-I type complications needed total pancreatectomy because of leakage of the pancreaticojejunostomy. CONCLUSION: Not only were there fewer complications for the R-Y type than for the Billroth-I type, but there was no need for operation to treat the complications of the R-Y type because of the isolated jejunal loop.
