Prevention of bile leakage after laparoscopic primary suturing of common bile duct by transabdominal placement of nasal bile duct / 中华肝胆外科杂志

Objective To study the advantages of laparoscopic primary suturing of common bile duct plus transabdominal nasobiliary drainage in reducing the rate of bile leakage.Methods The clinical data of laparoscopic primary suturing of common bile duct with or without nasal bile duct drainage in Second People's Hospital of Chengdu were analyzed retrospectively.Results During laparoscopic common bile duct exploration,286 patients were treated by primary suturing without nasobiliary drainage (group without drainage),including 32 (11.2％) patients with bile leakage;350 patients were treated by primary suturing with transabdominal nasobihary drainage (group with drainage),including 11 (3.1％) patients with bile leakage.The incidences of bile leakage of the two groups were significantly different (P ＜ 0.05).When the diameter of the common bile duct was less than 11.0 mm,the incidence of bile leakage in the non-drainage group and the drainage group were 18.5％ (20/108) and 2.1％ (3/143),respectively.The incidence in the drainage group was significantly lower than that in the non-drainage group,and the difference was statistically significant (P ＜ 0.05).When the diameter of common bile duct was larger than 11.0 mm,there was no significant difference in the incidences of bile leakage between the two groups (P ＞ 0.05).Conclusions The choice after laparoscopic primary suturing of common bile duct between with or without nasobiliary drainage should be determined according to the diameter of common bile duct.When a common bile duct diameter of less than 11.0 mm,nasobiliary drainage is recommended to reduce the rate of bile leakage.

Objective To explore the operative methods and indications of duodenoscopic papillotomy during the course of operation(IEPT)for cholelithiasis.Methods Cholecystectomy was firstly conducted under the condition of laparoscopy or open laparotomy.For the gross choledochus,the common bile duct was cut open to clear the stones.The ureteric catheter and zebra guidewire were inserted into the common bile duct and duodenum.Then they were inserted via duodenoscopy into thepapillum of duodenum.The papillary stenosis was removed with electro-knife by pin-head-like and arch-like to track along the ureteric catheter and zebra guidewire.For the tiny choledochus,the ureterie catheter and zebra guidewire were inserted via the cholecystic duct remnant into the common bile duct and duodenum.Then they were inserted via duodenoscopy to perform papillotomy to clear the stones of the common bile duct with the reticulation and the balloon of duodenoscopy.Results Forthe gross choledochus,IEPT in laparoscopy was successful in 45 cases and the other 2 received other operation.IEPT in open laparotomy was successful in 5 cases.For the tiny choledochus,IEPT in laparoscopy was successful in 73 cases and the other 1 underwent other operation.IEPT in open laparotomy was successfulin 2 cases.Conclusion If patients are suitable,IEPT is safe and effective in the hands of skilled endoscopiests for laparoscopy and open laparotomy.

Therapeutic laparoscopy combined with choledochoscopy or duodenoscopy in detail choledochus stones / 中华消化内镜杂志

Objective To evaluate combination of cholcdochoscopy or duodenoscopy with therapeutic laparoscopy (LCDCS) in treatment of detail choledochus stones. Methods Laparoscopic cholecystectomy was firstly performed and followed by choledochoscopy or duodenoscopy. Procedures of therapeutic choledochoscopy were as follows: choledochoscopic exploration via cystic duct remnant, choledochotomy, electrohydralic lithothipsy, drainage of bile duct with ureteral catheter via cystic duct remnant, T-tube drainage, or the suture of duct incision. Procedures of therapeutic duodenoscopy were as follows: access to the common bile duct and duodenum through ureteric catheter and zebra guidewire via cholecystic duct remnant, duodenoscopy via oral cavity into the duodenum papilla, papillotomy with needle-knife or arch-like electro-knife along the ureteric catheter or zebra guidewire, and stone clearance in the common bile duct with the reticulation and balloon of duodenescopy. Results Combination therapy were given to 191 cholelithiasis patients with detail choledochus stones. Combined choledochoscopy were performed in 117 patients. Stones were completely removed and average operation time was 114 min. Bile leakage occurred in 7 cases, but was cured with drainage. Postoperative imaging showed 2 cases of bile duct stenosis at primary closure of duct incision. Combined duodenescopic procedures were performed in 74 patients. Papillotomy and stone clearance were successfully performed in 68 patients, 5 others of whom underwent successful papillotomy only, and another underwent other operations. Average operation time was 97 min. Post-operation mild acut pancreatitis developed in 6 patients. No perforation of intestine or bile duct, bleeding, severe pancreatitis, or death was observed in each group. Conclusion LCDCS was safe and effective with appropriate indications.
