RESUMEN
Objective:To evaluate the preventive effect of indwelling pancreatic duct guide wire through nasobiliary drainage catheter for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in cholelithiasis patients with small-caliber pancreatic duct.Methods:The clinical data of 127 patients with gall bladder and common bile duct stones undergoing ERCP and elective laparoscopic cholecystectomy in the Cholelithiasis Center of Shanghai East Hospital Affiliated to Tongji University from January 2019 to June 2023 were analyzed retrospectively, including 55 males and 72 females, aged (56.95±10.86) years old. According to the preventive methods of PEP, patients were divided into the guide wire group (indwelling pancreatic duct guide wire through nasobiliary drainage catheter), stenting group (nasobiliary catheter with 5Fr 5 cm single pigtail pancreatic duct stent) and conventional group (nasobiliary catheter). The incidence of post-ERCP hyperamylasemia (PEH) and PEP were compared.Results:The incidence of PEH in the guide wire group was lower than that in the conventional group [17.8% (8/45) vs. 43.5% (10/23), P=0.023], and also lower than that in the stenting group [17.8% (8/45) vs. 32.2% (19/59)], despite no statistical significance ( P=0.337). The incidences of PEH were comparable in the stenting group and conventional group [32.2% (19/59) vs. 43.5% (10/23), P=0.096)]. The incidence of PEP in the guide wire group was lower than that in both the stenting group [6.7% (3/45) vs. 23.7% (14/59), P=0.030]. and conventional group [6.7% (3/45) vs. 30.4% (7/23), P=0.025]. The incidences of PEP were comparable in the stenting and conventional group [23.7% (14/59) vs. 30.4% (7/23), P=0.532]. Conclusion:Compared to the preventive pancreatic duct stenting, indwelling pancreatic duct guide wire through nasobiliary drainage catheter can effectively prevent the PEH and PEP in high-risk patients with a small-caliber pancreatic duct.

Objective:To study the feasibility and safety of percutaneous jejunal drainage in treatment of hepatolithiasis after choledochojejunostomy.Methods:The clinical data of 24 patients with hepatolithiasis after choledochojejunostomy treated by percutaneous jejunal drainage at the Cholelithiasis Center, Shanghai East Hospital Affiliated to Tongji University from May 2021 to May 2022 were retrospectively analyzed. There were 16 males and 8 females, aged (50.46±10.89) years old. Ultrasound and X ray guided percutaneous jejunography was performed under local anesthesia for patients with hepatolithiasis after choledochojejunostomy. Then the fistula was directly dilated to 16.0Fr, and percutaneous jejunal choledochoscopy was performed 3 days later. The success rate, complication rate and stone removal rate were analysed.Results:Twenty-four patients were treated with percutaneous jejunography, with a success rate of 79.2%(19/24), including 19 patients after anterior colonic cholangiojejunostomy with a success rate of 94.7%(18/19), and 5 patients after retrocolonic cholangiojejunostomy with a success rate of 20.0%(1/5). There was no complication including bleeding, intestinal leakage and bile leakage. In 19 patients with successful percutaneous jejunography, the success rate of fistula dilation was 100%(19/19), and there was no complication. Five patients with failed percutaneous jejunography underwent open choledocholithotomy through the jejunal output-loop, and bile leakage occurred in one patient. Thirteen patients with anastomotic stenosis, 5 with intrahepatic biliary strictures, and 6 with anastomotic and intrahepatic biliary strictures were diagnosed by choledochoscopy and selective cholangiography in these 24 patients. After choledochoscopic electrotomy, cylindrical balloon dilation, stone removal, stenting and other treatments, the stenosis relief rate was 100%(24/24), and the clearance rate of intrahepatic bile duct stones was 91.7%(22/24).Conclusion:Percutaneous jejunal drainage was a feasible, safe and minimally invasive method for treatment of hepatolithiasis after choledochojejunostomy. The procedure was especially suitable for patients with anterior colonic cholangiojejunostomy.
RESUMEN
Objective To study the feasibility, safety and aesthetics of laparoscopic cholecystectomy using a single-port through the umbilicus in patients with chronic cholecystitis with cholecystolithiasis. Methods From Jan 2007 to Jun 2017, the clinical data of 4790 patients who underwent single-port, 4426 patients conventional three-ports, and 3304 patients two-ports laparoscopic cholecystectomy were retrospec-tively studied. Results There were no death in all the three groups. There were no significant differences in the incidences of postoperative bleeding, bile leakage, biliary tract injury and other significant short-term complications (all P>0. 05). The operation time of transumbilical single-port laparoscopic cholecystectomy was significantly longer than that of two-ports and three-ports laparoscopic cholecystectomy [(35. 3 ± 9. 0) min vs. (28. 4 ± 7. 2)min vs. (23. 3 ± 6. 4)min, P<0. 05]. Looking only in a single year, there was no significant difference in the operation time of the three groups in the year 2017 (P>0. 05). There were no significant differences among the three groups in intraoperative blood loss, first postoperative passing of flatus, postoperative pain, and length of hospital stay (all P>0. 05). The satisfaction score of surgical scar in the single-port group was higher than that in the two-ports and three-ports groups [ ( 9. 6 ± 1. 6 ) vs. (7. 6 ± 1. 9) vs. (6. 7 ± 2. 0), P < 0. 05]. Conclusions Transumbilical single-port laparoscopic cholecystectomy was safe and feasible, with good aesthetics and other advantages. It was more difficult than the traditional laparoscopic technique. After the learning curve, the operation time could be comparable to the three-ports technique.
