ObjectiveTo compare the advantages and disadvantages of transumbilical single port (TUSP) and conventional laparoscopic cholecystectomy (LC). MethodsThe clinical data of 45 patients underwent elective LC were analyzed, 20 patients with TUSP LC (TUSP-LC group), 25 patients with conventional LC (conventional LC group). The operation time, Child-Pugh score and painkiller application frequency within three days after operation, the first time of out of bed and hospital stay after operation, intraoperative blood loss, chronic pain within one month after surgery were compared between two groups. ResultsAll cases were operated successfully except one patient in the conventional LC group. The frequency of painkiller application within three days after operation and postoperative hospital stay in the TUSP-LC group were better than those in the conventional LC group (Plt;0.05). There were no significant differences on postoperative chronic pain of surgical area within 1 month and Child-Pugh score between two groups (Pgt;0.05). The operation time and intraoperative blood loss in the conventional LC group were less than those in the TUSP-LC group (Plt;0.05, Plt;0.01). ConclusionTUSP LC has the advantages of small wound, slight pain, and fast recovery.
Objective To discuss the pathogeny， treatment and prophylactic measures of postcholecystectomy syndrome (PCS). Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed. Results Etiological factors were found in 131 patients: one hundred and twelve cases were due to the reasons of biliary system, including bile duct residual stones after cystic resection， the injury bile duct stenosis， a long residual cystic canal， nipple benign stricture, bile duct tumor etc; Nineteen examples were due to other reasons, including gallbladder stone merger reflux gastritis, gastroduodenal ulcer， diverticulum beside duodenal nipple, and so on, which resulted in the symptoms un-release after cystic resection. Nineteen cases were not found organic lesion. In ones whose etiological factors were definite, 117 cases were treated with different surgeries according to different etiological factors; another 33 cases were treated with conservative treatment. Total 145 cases were followed up, and 139 cases in them were cured or relieved at different degrees. Conclusion Careful preoperative examination, normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.
【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
【Abstract】Objective To study the clinical application of laparoscopic operation. Methods The clinical findings from 13 840 cases of laparoscopic surgery in this hospital from 1992 to 2005 were reviewed retrospectively.Results Laparoscopic operation were performed successfully in 13 653（98.6%）,187 cases were transferred to open operation. Complications were occurred in 115 cases, including common bile duct injury in 3 cases. Combined treatment with laparoscope and endoscope were performed in 162 cases. Eleven thousand three hundred and fiftytwo patients had been succeeded in followup survey. Over 90.0 percent of patients recovered smoothly. Conclusion Laparoscopic operation may be applied in a more extensive scope. The major complications can be reduced by strict procedures of laparoscopic operation. The combined treatment of laparoscope and endoscope should be further studied and widely used.
Objective To investigate the prevention and treatment strategy of bile duct injury (BDI) in laparoscopic cholecystectomy (LC). MethodsLatest progress was reviewed based on recent documents and the experience on BDI in LC in our department. ResultsWith the popularity of LC, BDI in LC is increasing. The reasons include illegibility and variability of local anatomy in gallbladder trigone,injury caused by galvanothermy, as well as operator’s overconfidence. In order to prevent BDI, we should apply more blunt dissection, not to use electrocogulation if possible and to study local anatomy and its variance clearly. The common bile duct and common hepatic duct should be clearly identified. Intraoperative cholangiography, laparoscopic ultrasonography and hepatobiliary scintigraphy are selections as necessary.The treatment of BDI depends on the type of BDI and its site and local condition.The treatment includes end to end anastomosis, repairing the defect, choledochoduodenostomy, RouxenY choledochojejunostomy and so on. T tube should be maintained in place for more than half a year after operation.Conclusion The key to improve the prognosis of BDI is prevention and treatment in proper time and in correct way.
ObjectiveTo introduce the experience in diagnosing and treating cholecystoenteric fistula (CEF) during laparoscopic cholecystectomy (LC). MethodsFive cases with CEF in a series of 4 200 LC cases were reviewed.All of the five patients were proved to have CEF during operations.There were four cholecystoduodenal fistulas and one cholecystocolic fistula. One case with cholecystoduodenal fistula was treated by a suturing of the fistula under laparoscopy; 1 case was closed with titaniun and 2 cases were converted to laparotomy and fistulectomy.The patient with cholecystocolic fistula clips was treated by a suturing of the fistula under laparoscopy. ResultsAll the patients had got good recovery without complications.Conclusion CEF is a rare complication of cholelithiasis.If the diagnosis is made before operation, open operation might be a better choice.But if the diagnosis was made during the LC operation, suture closure or clip closure or stapler closure of CEF under laparoscope might be chosen for an experienced surgeon.
Objective To evaluate the role of endoscopic retrograde cholangio-pancreatography(ERCP)in diagnosis of anomalous converge of the cystic duct and prevention of bile duct injuries during laparoscopic cholecystectomy(LC). Methods From July, 1992 to June, 1999, LCs were performed in 4 500 patients with gallbladder stone or cholecystitis at our center. Preoperative ERCPs were performed in 780 of all patients (14.50%). Anomalous junctions of the cystic duct with common hepatic duct were investigated and the length and caliber of these cystic duct were measured and compared with 100 control cases. Results An overall anomalous converges of the cystic duct were found in 125(16.03%) of the 780 patients undergoing ERCP. Of 780 patients undergoing LC, 35 cases were converted to open cholecystectomy(4.5%), and various complications occurred in 6 cases (0.77%), but no death and biliary duct injuries occurred. Conclusion Various types of anomalous junctions of the cystic duct could be diagnosed precisely by ERCP before LC and the preoperative examination of ERCP may be helpful in prevention of bile duct injuries and other biliary complications in the laparoscopic time.
Objective To comment the diagnosis and treatment the bile leakage from the injuried abnormal minute biliary in our laparosicopic cholecystectomy (LC) practice. Methods Fourteen cases of minute biliary duct injury in 2 050 cases of LC were studied retrospectively. Among them, 6 cases had been found the points of leakage during operation, and the points were treated by titanium nips. In 4 cases even though the bile leakage could be seen, but the points of leakage could not found, and were treated by drainage. Four cases with peritonitis, 1 needed to be explored, and treated with suture ligature, 1 was explored by laparoscopy again, another two cases were treated with multiple hole catheters to drainage of the abdominal cavities through stab wounds. Results All 14 cases recovered. Conclusion Small bile leakage in LC is almost inevitable. It is the best that the bile leakage can be discovered during operation and to be treated. If it is discovered after operation, an open or laparoscopic exploratory laparotomy and adequate drainage would be needed. In the case of small amount of leakage, catheter drainage through stab wound is feasible.
The aim of this study was to evaluate ultrasonic findings as predictor of potential operative difficulties and complications during laparoscopic cholecystectomy (LC). From Auguest 1995 to December 1996 a total of 328 patients with symptomatic cholelithiasis (92 males, 236 females, mean age 45±17 years) were examined by ultrasonography (US) 1 to 3 days before LC. The US examination assessed six paramenters: (GB) volume of gallbladder thichness of GB wal position of neck of GB, stone mobility, maximal size of stone, and GB adhesions. On the basis of these US findings, a predictive judgment of technical difficulties was expressed as easy, difficult, and very difficult. Two hundred and twenty five patients presented with uncomplicated symptomatic cholelithiasis, and 103 had acute cholecystitis. The operation was predicted to be easy in 38% of cases, difficult in 48% and very difficult in 14% with a good correlation with the surgeon’s intraoperative judgment (Ｐ＜0.01). A significant association was found between stone mobility (Ｐ＜0.01), presence of adhesions (Ｐ＜0.01) and the difficulty of the procedure. Our results suggest that preoperative US is a useful screening test for patients undergoing LC, and it can help predict technical difficulties during LC.
To analyse the causes of biliary injuries and summuarize the experience of prevention of biliary injury during laparoscopic cholecystectomy (LC). Twenty-three patients with biliary duct injury were diagnosed and treated at our center between September 1992 and August 1998. The main causes were either misidentification of the bile duct or aberrant right duct as the cystic or injudicious use of thermal energy (cautery) to dissect, control bleeding, or divide tissue. Conclusion: The causes of biliary duct injury are complex. Training and experience of sugeon, the meticulous dissection of the calot′s triangle and preoperative or operative cholangiography are three key factors in prevention of biliary duct injury during LC.
