Postoperative Endoscopic Retrograde Cholangiopancreatography Research Articles

The Surgical Management of Concomitant Gallbladder and Common Bile Duct Stones.

Background. The management of choledocholithiasis has evolved from open common bile duct exploration (OCBDE) to therapeutic endoscopic retrograde cholangiopancreatography (ERCP) to laparoscopic common bile duct exploration (LCBDE). Each entails a degree of difficulty. Aim. To review 5-year results of bile duct exploration in an UGI unit. Methods. Common bile duct explorations (CBDEs) performed between January 2008 and January 2013 were identified from a prospectively collected clinical audit system and results reviewed retrospectively. Results. 216 CBDEs were performed, 119 (55%) as an emergency and 52 (24%) following failed ERCP. Open CBDE (OCBDE) was performed primarily in 34/216 (16%) patients and attempted laparoscopically in 182 (84%). Fifty nine (32%) Laparoscopic CBDEs (LCBDEs) were converted to OCBDE. Of the remaining 123 LCBDEs, 51 (41%) primary choledochotomies and 72 (59%) primary transcystic CBDEs (TC-CBDEs) were performed. Forty nine (68%) TC-CBDEs were considered successful and 23 (32%) failed. Fifteen failed TC-CBDEs were converted to a successful laparoscopic choledochotomy. Ductal clearance was achieved in 187/216 (87%) patients and retained stones were identified in 20/123 (16%) LCBDEs. Complications occurred in 52/216 (24%) patients. There were 8/216 (4%) bile leaks requiring further intervention. Postoperative ERCP was carried out in 32/216 (15%) patients and 9/216 (4%) required relaparoscopy/laparotomy. No patient died. Conclusions. Successful management of choledocholithiasis requires a breadth of laparoscopic and endoscopic expertise.

Initial Cholecystectomy with Cholangiography Decreases Length of Stay Compared to Preoperative MRCP or ERCP in the Management of Choledocholithiasis

There are several treatments available for choledocholithiasis, but the optimal treatment is highly debated. Some advocate preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC) with cholangiography (IOC). Others advocate initial LC + IOC followed by common bile duct exploration or ERCP. The purpose of this study was to determine whether initial LC + IOC had a shorter length of stay (LOS) compared with preoperative magnetic resonance cholangiopancreatography (MRCP) or ERCP. Patients who underwent cholecystectomy between 2012 and 2013 at two institutions were reviewed. Patients were selected if they had suspected choledocholithiasis, indicated by dilated CBD and/or elevated bilirubin, or confirmed choledocholithiasis. They were excluded if they had pancreatitis or cholangitis. There were 126 patients with suspected choledocholithiasis in this study. Of these, 97 patients underwent initial LC ± IOC with an average LOS of 3.9 days. IOC was negative in 47.4 per cent patients, and they had a shorter LOS compared with positive IOC patients (2.93 vs 4.82, P < 0.001). Laparoscopic common bile duct exploration was successful in 64.7 per cent and had a shorter LOS compared with postoperative ERCP patients (P = 0.01). Preoperative MRCP was performed in 21 patients with an average LOS of 6.48 days. Preoperative ERCP was performed in eight patients with an average LOS of seven days. Initial LC+IOC is associated with a shorter LOS compared to preoperative MRCP or ERCP. It is recommended as the optimal treatment choice for suspected choledocholithiasis.

Surgeons, ERCP, and laparoscopic common bile duct exploration: do we need a standard approach for common bile duct stones?

Variation exists in the management of choledocholithiasis (CDL). This study evaluated associations between demographic and practice-related characteristics and CDL management. A 22-item, web-based survey was administered to US general surgeons. Respondents were classified into metropolitan or nonmetropolitan groups by zip code. Univariate tests and multivariable logistic regression were used to determine factors associated with CDL management preferences. The survey was sent to 32,932 surgeons; 9902 performed laparoscopic cholecystectomy within the last year; 750 of 771 respondents had a valid US zip code and were included in the analysis. Mean practice time was 18 ± 10 years, 87% were male, and 83% practiced in a metropolitan area. For preoperatively known CDL, 86% chose preoperative endoscopic retrograde cholangiopancreatography (ERCP). Those in metropolitan areas were more likely to select preoperative ERCP than those in nonmetropolitan areas (88 vs. 79%, p < 0.001). For CDL discovered intraoperatively, 30% selected laparoscopic common bile duct exploration (LCBDE) as their preferred method of management with no difference between metropolitan and nonmetropolitan areas (30 vs. 26%, p = 0.335). The top reasons for not performing LCBDE were: having a reliable ERCP proceduralist available, lack of equipment, and lack of comfort performing LCBDE. Factors associated with preoperative ERCP were: metropolitan status, selective intraoperative cholangiography (IOC), and availability of a reliable ERCP proceduralist. Those who perform selective IOC were 70% less likely to prefer LCBDE (OR 0.32, 95% CI 0.18-0.57, p < 0.001). Those with a reliable ERCP proceduralist available were 90% less likely to prefer LCBDE (OR 0.10, 95% CI 0.04-0.26, p < 0.001). The majority of respondents preferred ERCP for the management of CDL. Having a reliable ERCP proceduralist available, use of selective IOC, and metropolitan status were independently associated with preoperative ERCP. Postoperative ERCP was preferred for managing intraoperatively discovered CDL. Many surgeons are uncomfortable performing LCBDE, and increased training may be needed.

Subtotal cholecystectomy for "difficult gallbladders": systematic review and meta-analysis.

Subtotal cholecystectomy (SC) is a procedure that removes portions of the gallbladder when structures of the Calot triangle cannot be safely identified in "difficult gallbladders." To conduct a systematic review and meta-analysis to evaluate current studies and present an evidence-based assessment of the outcomes for the techniques available for SC. A literature search of the PubMed/MEDLINE (1954 to November 2013) and EMBASE (1974 to November 2013) databases was conducted. Search criteria included the words subtotal, partial, insufficient or incomplete, and cholecystectomy. Inclusion criteria were all randomized, nonrandomized, and retrospective studies with data on SC techniques and outcomes. Exclusion criteria were studies that reported data on SC along with other interventions (eg, cholecystostomy) without the possibility to discriminate results specific to SC. This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The primary outcome of the study was the occurrence of common bild duct injury. Secondary outcomes included the occurrence of other SC-related morbidities, such as hemorrhage, subhepatic collection, bile leak, retained stones, postoperative endoscopic retrograde cholangiopancreatography, wound infection, reoperation, and mortality. Thirty articles were included. Subtotal cholecystectomy was typically performed using the laparoscopic technique (72.9%), followed by the open (19.0%) and laparoscopic converted to open (8.0%) techniques. The most common indications were severe cholecystitis (72.1%), followed by cholelithiasis in liver cirrhosis and portal hypertension (18.2%) and empyema or perforated gallbladder (6.1%). Morbidity rates were relatively low (postoperative hemorrhage, 0.3%; subhepatic collections, 2.9%; bile duct injury, 0.08%; and retained stones, 3.1%); the rate for bile leaks was higher (18.0%). Reoperations were necessary in 1.8% of the cases; the 30-day mortality rate was 0.4%. The laparoscopic approach produced less risk of subhepatic collection (odds ratio [OR], 0.4; 95% CI, 0.2-0.9), retained stones (OR, 0.5; 95% CI, 0.3-0.9), wound infection (OR, 0.07; 95% CI, 0.04-0.2), reoperation (OR, 0.5; 95% CI, 0.3-0.9), and mortality (OR, 0.2; 95% CI, 0.05-0.9) but more bile leaks (OR, 5.3; 95% CI, 3.9-7.2) compared with the open approach. Subtotal cholecystectomy is an important tool for use in difficult gallbladders and achieves morbidity rates comparable to those reported for total cholecystectomy in simple cases. The various technical differences appear to influence outcomes only for the laparoscopic approach.

De Novo Stent-Stone Complex Formation With Resultant Secondary Sclerosing Cholangitis: A Case Report and Literature Review

Introduction: Long-term biliary stenting, especially unintended and forgotten stents, could cause lifethreatening complications. We report a case of 23-year-old female who had unintended long-term biliary stenting that resulted in obstructive jaundice and secondary sclerosing cholangitis, which carries high morbidity and mortality. Case Report: A 23-year-old female underwent laparoscopic cholecystectomy with intraoperative cholangiogram showing choledocholithiasis. Postoperative endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting was done and patient was recommended to follow-up with gastroenterology in 1 week for repeat ERCP. Patient was lost the follow-up and after 5 years she presented with right upper quadrant pain and obstructive jaundice. First ERCP showed stentstone complex which could not be removed with conventional methods and mechanical lithotripsy. A new stent was placed and sphincterotomy was done. During second ERCP with SpyGlass® and electrohydraulic lithotripsy, multiple attempts were again unsuccessful. She had surgical common bile duct (CBD) exploration, stone-stent complex was removed and T-tube was placed. Liver biopsy done during surgery showed cholestasis and portal reactive inflammation and fibrosis, consistent with large bile duct obstruction. Discussion: Retained foreign objects including stents, fragments of T-tube, surgical clips, and suture material can act as a nidus for stone formation. Complications associated with long-term biliary stents include stent occlusion, recurrent cholangitis, biliary colic, stent migration, CBD ulceration, fistula formation, perforation, formation of stent-stone complexes, and chronic biliary obstruction resulting in secondary sclerosing cholangitis. For stent-stone complex 2 hypothesized mechanisms were proposed in a case series: type A and type B. Secondary sclerosing cholangitis (SSC) has features similar to primary sclerosing cholangitis (PSC), but with known pathologic processes causing chronic biliary obstruction, most commonly from surgical trauma followed by biliary stones. Other reported causes include biliary tumors, ischemia, chemicals such as floxuridine used in treatment of metastatic colon cancer, antibiotics, and cystic fibrosis. SSC patients have shorter life expectancy compared to PSC. It is recommended to closely monitor SSC patients with 3-6 months of liver function tests, Imaging studies for cholangiocarcinoam and hepatoma and also screening for esophageal varices. Our case emphasizes on judicious use of long-term biliary stents and close follow-up because of the risk of life-threatening complications. Permanent biliary stents should be restricted to patients unfit for elective procedure later on or with limited life expectancy.

Using balloon-overtube-assisted enteroscopy for postoperative endoscopic retrograde cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is technically more challenging in patients with postsurgical anatomy such as Roux-en-Y anastomosis, frequently mandating an operative intervention. Although limited, there is growing evidence that ERCP can be performed using the balloon-overtube-assisted enteroscopy (BOAE) in patients with complex postoperative anatomy. We present the technical aspects of performing ERCP with the BOAE in patients presenting with complex postsurgical anatomy having biliary problems. ERCP using the BOAE is feasible in patients with complex postsurgical anatomy, permitting diagnostic and therapeutic interventions in 80% of patients.

Management of choledocholithiasis in an emergency cohort undergoing laparoscopic cholecystectomy: a single-centre experience

IntroductionMinimally-invasive options for the management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy include laparoscopic and endoscopic approaches. This study reviews the effectiveness of both approaches in an emergency setting. MethodsA retrospective chart review was performed for a cohort of patients who underwent laparoscopic cholecystectomy. Outcomes assessed were duct clearance, the number of procedures performed (NPP), length of stay (LOS) and complication rate. ResultsA total of 182 patients who underwent emergency laparoscopic cholecystectomies received intervention for choledocholithiasis. The duct clearance rate was lower in the laparoscopic group, 63% versus 86% (P = 0.001). However, the median NPP was also lesser in the laparoscopic group, 1 (interquartile range (IQR) 1–2) versus 2 (IQR 2–2) (P < 0.001), as was the median LOS, 5 days (IQR 3–8) versus 7 days (IQR 6–10) (P = 0.009). Forty-eight laparoscopic endobiliary stents were attempted; stent deployment was successful in 37 patients. A larger proportion of patients with laparoscopic endobiliary stents had duct clearance by endoscopic retrograde cholangiopancreatography (ERCP) compared with those without, although this was not statistically significant (P = 0.208). ConclusionLaparoscopic clearance is not as effective as post-operative ERCP in an emergency cohort, but is associated with fewer procedures required and a shorter inpatient stay. Thus, laparoscopic clearance may still be an attractive option for surgeons especially where conditions are favourable during an emergency laparoscopic cholecystectomy.

Laparoscopic cholecystectomy in the pediatric population: a single-center experience.

We aimed to review our experience with laparoscopic cholecystectomy in the pediatric population to better understand the associated complications and outcomes. We performed a retrospective chart review of children below 18 years of age who underwent laparoscopic cholecystectomy at a single academic institution between the years 1990 and 2010. Of the 325 cases of cholecystectomy, 202 (62.2%) were performed laparoscopically. The primary indication for surgery was symptomatic cholelithiasis (45.5%, n=92). Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 25 (12.4%) patients. Variations in anatomy and technical difficulties (eg, presence of adhesions) were observed in 45 (22.3%) patients. Intraoperative cholangiogram was performed in 20 (9.9%) patients and 16 (7.9%) underwent concomitant splenectomy. Only 8 (4%) of the cases were converted to an open approach because of lack of anatomic clarity. There were zero common bile duct injuries; however, spillage of bile was present in 12 (5.9%) patients. Postoperative complications including wound infection, retained stones, abdominal abscess, and biloma, were observed in 9 patients (4.5%). The median operative time was 117.5 minutes. The median postoperative hospital stay was 1 day. Nineteen (9.4%) patients had recurrence of abdominal pain without associated pathology. Three patients (1.5%) required postoperative ERCP. The average follow-up period was 54 months. Laparoscopic cholecystectomy in the pediatric population results in short postoperative hospital stay and has low complication rates. In particular, zero bile duct injuries were noted.

Su1645 Evaluation of Patients With Suspected Bile Duct Stone on Intraoperative Cholangiogram (IOC): Should Endoscopic Retrograde Cholangiopancreatography (ERCP) Be the Initial Study of Choice?

ERCP is currently the method of choice for the postoperative evaluation of suspected bile duct stones seen on IOC. The false positive rate of IOC has ranged widely in prior studies, from 2-60% and it is unclear whether there are specific predictors that could be used risk stratify patients to undergo postoperative ERCP vs. less invasive diagnostic testing.

Endoscopic retrograde cholangiopancreatography in the treatment of intraoperatively demonstrated choledocholithiasis

INTRODUCTIONThe aim of this study was to determine the efficacy and complications of postoperative endoscopic retrograde cholangiopancreatography (ERCP) in confirming and treating choledocholithiasis found at intraoperative cholangiography during laparoscopic cholecystectomy.METHODSPatients who had undergone ERCP following a cholecystectomy between 2008 and 2011 with an indication of intraoperative cholangiography findings consistent with choledocholithiasis were identified from a prospectively collected database of a single endoscopist. Deep biliary access rate, confirmation of choledocholithiasis, clearance rate of bile duct stones, delay between cholecystectomy and postoperative ERCP, and the complication rates following the procedure were analysed.RESULTSThe median age of the 41 patients (16 male, 25 female) was 42 years (range: 18–82 years). Sixteen surgeons performed the operations with a median delay of 6 days (range: 1–103 days) between cholecystectomy and postoperative ERCP. Common bile duct access was achieved in 100% of the patients, with ERCP taking a median time of 16 minutes (range: 6–40 minutes). Initial ERCP confirmed the presence of a stone in 30 patients (73%) and successful stone removal occurred in 28 of these 30 patients (93%) during the first ERCP and in the remaining 2 on a subsequent ERCP. Following ERCP, two patients (4.9%) experienced extended hospital stays for four and eight days owing to complications, including one patient (2.4%) with mild acute pancreatitis.CONCLUSIONSThis study demonstrates that postoperative ERCP is highly effective in both confirming and treating choledocholithiasis. However, there is a significant risk of short-term complications that must be taken into consideration when deciding management.

Single-session minimally invasive management of common bile duct stones.

Up to 18% of patients submitted to cholecystectomy had concomitant common bile duct stones. To avoid serious complications, these stones should be removed. There is no consensus about the ideal management strategy for such patients. Traditionally, open surgery was offered but with the advent of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) minimally invasive approach had nearly replaced laparotomy because of its well-known advantages. Minimally invasive approach could be done in either two-session (preoperative ERCP followed by LC or LC followed by postoperative ERCP) or single-session (laparoscopic common bile duct exploration or LC with intraoperative ERCP). Most recent studies have found that both options are equivalent regarding safety and efficacy but the single-session approach is associated with shorter hospital stay, fewer procedures per patient, and less cost. Consequently, single-session option should be offered to patients with cholecysto-choledocholithiaisis provided that local resources and expertise do exist. However, the management strategy should be tailored according to many variables, such as available resources, experience, patient characteristics, clinical presentations, and surgical pathology.

Contemporary Experience with Cholecystectomy: Establishing ‘Benchmarks’ Two Decades after the Introduction of Laparoscopic Cholecystectomy

With quality and public reporting of increasing importance, benchmarks are anticipated to grow in relevance. We studied cholecystectomy in a practice in an urban tertiary care hospital. A total of 1083 cholecystectomies were performed in 2008 and 2009. Laparoscopic cholecystectomy was performed in 97.8 per cent of patients with a 2.2 per cent conversion rate. A planned open procedure was performed in only 2.2 per cent of patients. Approximately half of procedures were urgent and performed during an acute hospitalization. Most patients (74%) were female and most patients were overweight or obese (64.8%). Ages into the tenth decade of life were represented. Comorbidities included hypertension, 28.7 per cent; coronary disease, 15.6 per cent; diabetes mellitus, 13.4 per cent; gastroesophageal reflux disease, 10.7 per cent; and asthma, 5.5 per cent. Of female patients, 98 (12.2%) were postpartum and five (0.6%) were pregnant. Of 137 patients without gallstones, 59.1 per cent had biliary dyskinesia and 27 per cent had acalculous cholecystitis. Preoperative magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) were performed in most patients with suspected choledocholithiasis. Intraoperative cholangiograms were performed in 6.9 per cent of patients, 3.3 per cent for abnormal liver function studies. Postoperative ERCP was used in most patients with positive intraoperative cholangiograms. All-cause mortality was 0.8 per cent and attributable mortality was 0.2 per cent. Complications occurred in 7.5 per cent of patients, including retained common bile duct stones in 1.1 per cent, bile duct leak in 0.3 per cent, and common bile duct injury in 0.1 per cent.

Laparoscopic Techniques for Safe and Successful Removal of Common Bile Duct Stones in Pediatric Patients

Choledocholithiasis is uncommon in the pediatric population. Techniques for common bile duct stone extraction are still not well established. This article aims to describe safe and applicable techniques for pediatric common bile duct exploration. This was a retrospective review of a prospectively maintained database of two pediatric surgeons for patients undergoing laparoscopic common bile duct exploration at two tertiary-care centers from April 2008 to March 2012. For 39 patients under 15 years of age undergoing laparoscopic cholecystectomy, 10 cholangiograms were performed, and 8 were found to have filling defects. Seven patients underwent successful laparoscopic common bile duct exploration with documentation of stone clearance, and 1 patient was sent for postoperative endoscopic retrograde cholangiopancreatography with stone extraction. Eleven patients had cholecystectomy performed by single-incision laparoscopic surgery, but none of these had cholangiograms or common bile duct explorations. Various methods of stone clearance were used, including the use of saline flush, balloon catheters, nitinol stone extractors, and the aide of glucagon. Depending on patient size, a choledochosope or a ureteroscope was used. There were no complications and no conversions to open surgery. Laparoscopic common bile duct exploration is feasible in the pediatric population, using many of the instruments readily available in the standard operating room. With an armamentarium of tools and techniques, the method of stone extraction can be tailored to the patient and situation.

Routine cholangiography during rigid-hybrid transvaginal natural orifice transluminal endoscopic cholecystectomy

Transvaginal rigid-hybrid transluminal endoscopic cholecystectomy (tvCCE) has become a routine procedure in some laparoscopic departments in recent years. Although intraoperative cholangiography is an important adjunct to cholecystectomy, its feasibility and safety in tvCCE have not been demonstrated to date. Patients undergoing tvCCE between April and October 2012 were included in this study. An intraoperative cholangiogram was obtained routinely for all the patients. Patient characteristics, operation data, feasibility, and duration of the cholangiography as well as the postoperative course were recorded prospectively. For 32 (97 %) of the 33 patients enrolled in this study, intraoperative cholangiography could be performed successfully. The median duration of cholangiography was 6 min (interquartile range, 4-7 min). Common bile duct stones were detected in three patients (10 %). Laparoscopic bile duct revision with the aid of one additional port was successful in two of these patients. One patient needed postoperative endoscopic retrograde cholangiopancreatography due to the impossibility of extracting an impacted prepapillary concrement. One operation was converted to a four-port laparoscopic cholecystectomy. One additional port was used in 11 patients (33 %) and two additional ports in three patients (9 %). Three intraoperative minor complications (9 %) and one postoperative minor complication (3 %) occurred. Intraoperative cholangiography during tvCCE is feasible, safe, and easy to perform. The need for intraoperative cholangiography no longer represents a contraindication for tvCCE.

Emergency Biliary Sonography: Utility of Common Bile Duct Measurement in the Diagnosis of Cholecystitis and Choledocholithiasis

BackgroundMeasurement of the common bile duct (CBD) has traditionally been considered an integral part of gallbladder sonography, but accurate identification of the CBD can be difficult for novice sonographers. ObjectiveTo determine the prevalence of isolated sonographic CBD dilation in emergency department (ED) patients with cholecystitis or choledocholithiasis without laboratory abnormalities or other pathologic findings on biliary ultrasound. MethodsWe conducted a retrospective chart review on two separate ED patient cohorts between June 2000 and June 2010. The first cohort comprised all ED patients undergoing a biliary ultrasound and subsequent cholecystectomy for presumed cholecystitis. The second cohort consisted of all ED patients receiving a biliary ultrasound who were ultimately diagnosed with choledocholithiasis. Ultrasound data and contemporaneous laboratory values were collected. Postoperative gallbladder pathology reports and endoscopic retrograde cholangiopancreatography (ERCP) reports were used as the criterion standard for final diagnosis. ResultsOf 666 cases of cholecystitis, there were 251 (37.7%) with a dilated CBD > 6 mm and only 2 cases (0.3%; 95% confidence interval [CI] 0.0–0.7%) of isolated CBD dilation with an otherwise negative ultrasound and normal laboratory values. Of 111 cases of choledocholithiasis, there were 80 (72.0%) with a dilated CBD and only 1 case (0.9%; 95% CI 0.0–2.7%) with an otherwise negative ultrasound and normal laboratory values. ConclusionThe prevalence of isolated sonographic CBD dilation in cholecystitis and choledocholithiasis is <1%. Omission of CBD measurement is unlikely to result in missed cholecystitis or choledocholithiasis in the setting of a routine ED evaluation with an otherwise normal ultrasound and normal laboratory values.

A practical cost-effective management strategy for gallstone pancreatitis

BackgroundThe purpose of this study was to evaluate the outcomes of various surgeon strategies used to evaluate and treat common duct stones (CDSs) in patients presenting with mild to moderate gallstone pancreatitis (GP). MethodsWe performed a retrospective review of patients admitted for mild to moderate GP. Data variables included laboratory values and radiology images, indications for and findings of intraoperative cholangiogram (IOC) and endoscopic retrograde cholangiopancreatography (ERCP), length of stay (LOS), and hospital charges. Data were stratified by 2 different management strategies: preoperative ERCP and then laparoscopic cholecystectomy (LC) or LC with IOC followed by selective postoperative ERCP. ResultsDuring this time period, 80 patients met the study criteria, 56 were treated by LC with IOC, and 24 had a preoperative ERCP performed. The incidence of CDS was 33% (n = 26). The presence of CDSs correlated with an elevated total bilirubin at admission (CDSs 3.5 mg/dL vs 2.1 mg/dL no CDSs, P < .01) and 24 hours after admission (CDS 3.2 mg/dL vs 1.5 mg/dL no CDS, P < .01). Patients who had an IOC compared with those who had preoperative ERCP had a shorter LOS (4.6 vs 5.9 days, P = .04) and lower hospital charges (US $28,510 vs US $38,620; P < .01). ConclusionsElevated total bilirubin at admission and 24 hours after admission may predict a patient's risk for CDS. We found that the management of uncomplicated GP with early LC and IOC results in decreased LOS and total hospital charges when compared with preoperative ERCP.

Optimum cystic duct closure: a comparative study using metallic clips, ENSEAL, and ENDOLOOP in swine

BackgroundMetal clips are commonly used to secure the cystic duct during cholecystectomy, although use of an ENDOLOOP (Ethicon Endo-Surgery, Blue Ash, OH) is often touted as a more secure closure when postoperative endoscopic retrograde cholangiopancreatography (ERCP) is anticipated. The objective of this study was to test the strength of 3 different cystic duct closure methods in a model simulating postoperative biliary insufflation. MethodsThe extrahepatic biliary system, including common bile duct, gallbladder, and cystic duct, was harvested en bloc from 22 swine postmortem. A cholecystectomy was performed and the cystic duct was secured using 1 of 3 randomly assigned methods: metallic clips (Ethicon Endo-Surgery), an ENDOLOOP (Ethicon Endo-Surgery), or an ENSEAL tissue sealing device (Ethicon Endo-Surgery). The common bile duct was cannulated with a pressure-monitoring system and insufflated with air. The burst pressures, location of rupture, and size of the common bile duct and cystic duct were recorded and compared. ResultsThere were 7 pigs each in the ENDOLOOP and ENSEAL groups and 8 in the metallic clip group, with no statistical significance between cystic and common bile duct size. Mean burst pressure was 432 mm Hg for metallic clips, 371 mm Hg for the ENDOLOOP, and 238 mm Hg for the ENSEAL device (P = .02). Post hoc analysis revealed clips to be statistically superior when compared with the ENSEAL (P= .01). There was no statistical difference between the ENDOLOOP and metal clips or between the ENDOLOOP and the ENSEAL. ConclusionsAll 3 closure methods successfully secured the cystic duct, with mean burst pressures exceeding 195 mm Hg. Metallic clips demonstrated the highest burst pressures and no cystic duct stump leaks. This study challenges the traditional dogma of additionally securing the cystic duct with an ENDOLOOP when postoperative biliary instrumentation is expected and also suggests that an adequately secure closure may be obtained with thermal sealing devices.

A modified Rendezvous ERCP technique in duodenal diverticulum

To postoperative endoscopic retrograde cholangiopancreatography (ERCP) failure, we describe a modified Rendezvous technique for an ERCP in patients operated on for common bile duct stone (CBDS) having a T-tube with retained CBDSs. Five cases operated on for CBDSs and having retained stones with a T-tube were referred from other hospitals located in or around Istanbul city to the ERCP unit at the Haydarpasa Numune Education and Research Hospital. Under sedation anesthesia, a sterile guide-wire was inserted via the T-tube into the common bile duct (CBD) then to the papilla. A guide-wire was held by a loop snare and removed through the mouth. The guide-wire was inserted into the sphincterotome via the duodenoscope from the tip to the handle. The duodenoscope was inserted down to the duodenum with a sphincterotome and a guide-wire in the working channel. With the guidance of a guide-wire, the ERCP and sphincterotomy were successfully performed, the guide-wire was removed from the T-tube, the stones were removed and the CBD was reexamined for retained stones by contrast. An ERCP can be used either preoperatively or postoperatively. Although the success rate in an isolated ERCP treatment ranges from up to 87%-97%, 5%-10% of the patients require two or more ERCP treatments. If a secondary ERCP fails, the clinicians must be ready for a laparoscopic or open exploration. A duodenal diverticulum is one of the most common failures in an ERCP, especially in patients with an intradiverticular papilla. For this small group of patients, an antegrade cannulation via a T-tube can improve the success rate up to nearly 100%. The modified Rendezvous technique is a very easy method and increases the success of postoperative ERCP, especially in patients with large duodenal diverticula and with intradiverticular papilla.

Routine Intraoperative Cholangiography During Single-Incision Laparoscopic Cholecystectomy: a Review of 196 Consecutive Patients

BackgroundSingle-incision laparoscopic cholecystectomy (SILC) has been increasingly performed as a potentially less invasive alternative to standard laparoscopic cholecystectomy. However, recent evidences suggest a higher incidence of complications, notably bile duct injuries, in SILC. We reviewed our experiences with routine intraoperative cholangiography (IOC) during SILC to investigate its feasibility and usefulness. MethodsAmong 228 patients who underwent SILC at our institution from September 2009 to July 2012, a total of 196 patients in which an IOC was attempted were retrospectively reviewed. ResultsIOC was successful in 178 of 196 patients, yielding a success rate of 90.8 %. There were no IOC-related complications. Common bile duct (CBD) stones were detected by IOC in 16 patients (8.2 %), all of which were treated by subsequent single-incision laparoscopic CBD exploration or postoperative endoscopic retrograde cholangiopancreatography with stone extraction. In addition, IOC revealed filling defects in the cystic duct (four patients) and poor passage of contrast medium into the duodenum (one patient). In one patient with severe acute cholecystitis, cholangiography via an endoscopic nasobiliary drainage tube revealed misinterpretation of CBD as cystic duct. ConclusionsWe, thus, conclude that routine IOC during SILC is feasible and useful to detect biliary stones and to gain an accurate picture of biliary anatomy.
