Laparoscopic cholecystectomy and laparoscopic common bile duct exploration for cholecystolithiasis and choledocholithiasis in a patient with situs inversus totalis: A case report.

Situs inversus complicates diagnosis and treatment due to the mirrored organ placement in relation to normal anatomy. This report describes a 78-year-old female patient with situs inversus totalis who underwent laparoscopic cholecystectomy and laparoscopic common bile duct exploration for cholecystolithiasis and choledocholithiasis. Utilizing the "French mirror technique" for port placement, the surgeon adeptly mirrored standard maneuvers with a 2-mm needle forceps in the left hand and a 5-mm forceps in the right in a reversed anatomical setting. This technique maintained familiar hand movements, despite the patient's unique anatomy. The surgeon applied transcystic ductal bile duct exploration, using choledochoscopy for duct exploration and a basket catheter for stone removal. Laparoscopic cholecystectomy and common bile duct exploration through the transcystic ductal route are viable and effective for patients with situs inversus.

Unexpected finding: a patient with choledocholithiasis found mass at the lower end of common bile duct.

Antegrade balloon dilatation of the duodenal papilla during laparoscopic cholecystectomy versus endoscopic retrograde cholangiography in patients with acute choledocholithiasis: a case control matched study.

INTRODUCTION: In acute obstructive common bile duct (CBD) stones endoscopic retrograde cholangiography for CBD stone removal before cholecystectomy (ChE) ('ERC-first') is the gold standard of treatment. Intraoperative antegrade balloon dilatation of the duodenal papilla during ChE with flushing of CBD stones to the duodenum ('ABD-during-ChE') may be an alternative 'one-stop-shop' treatment option. However, a comparison of outcomes of the 'ABD-during-ChE' technique and the'ERC-first' approach has never been performed. METHODS: Retrospective case control matched study of patients suffering from obstructive CBD stones (< 8 mm) without severe pancreatitis or cholangitis that underwent the traditional 'ERC-first' approach versus the 'ABD-during-ChE' technique. Primary endpoint was the overall Comprehensive Complication Index (CCI®) from diagnosis to complete CBD stone removal and performed ChE. RESULTS: A total of 70 patients were included (35 patients each in the 'ERC first'- and 'ABD-during-ChE'-group). There were no statistical significant differences in terms of demographics and disease specific characteristics between the two study groups. However, there was a not significant difference towards an increased overall CCI® in the 'ERC-first' group versus the 'ABD-during-ChE' group (14.4 ± 15.4 versus 9.8 ± 11.1, p = 0.225). Of note, six major complications (Clavien-Dindo classification ≥ IIIa) occurred in the 'ERC-first' group versus two in the 'ABD-during-ChE' group (17% versus 6%, p = 0.136). In addition, significantly more interventions and a longer overall time from diagnosis to complete clearance of bile ducts and performed ChE was found, when comparing the 'ERC-first' group and the 'ABD-during-ChE' group (3.7 ± 0.8 versus 1.1 ± 0.4, p < 0.001; 160.5 ± 228.6 days versus 12.0 ± 18.0 days, p < 0.001). CONCLUSION: In patients suffering from acute obstructive CBD stones smaller than 8 mm, compared to the 'ERC-first' approach, the 'ABD-during-ChE' technique resulted in significantly less interventions and reduced overall treatment time from diagnosis to complete clearance of bile ducts and performed ChE. This comes together with a strong trend of less intervention related complications in the 'ABD-during-ChE' group.

Choledocoduodenal Biliary Bypass for Recurrent Choledocholithiasis in a Patient with Gastric Bypass: An Old Trick to Solve a Modern Problem.

Bariatric patients are at risk for developing biliary stones. Choledocholithiasis poses a significant challenge in Roux-en-Y gastric bypass patients due to anatomical changes, complicating the treatment. We present a case of a 71-year-old female with recurrent choledocholithiasis post-bariatric surgery. After failed endoscopic attempts, a biliodigestive bypass with choledocoduodenal anastomosis was performed successfully using the Da Vinci robotic platform. This technique offers a single anastomosis, excluding the duodenum from transit, preventing food reflux. The patient had an uneventful recovery with no recurrence after 1 year. The choledocoduodenal anastomosis is a viable option for biliary diversion in patients with challenging endoscopic access post-gastric bypass, offering favorable outcomes.

Urgent one-stage endoscopic treatment for choledocholithiasis related moderate to severe acute cholangitis: A propensity score-matched analysis.

BACKGROUND: During emergency endoscopic retrograde cholangiopancreatography (ERCP), the safety and feasibility of performing one-stage endoscopic treatment for patients with acute cholangitis (AC) due to choledocholithiasis are unclear. AIM: To investigate the safety and feasibility of one-stage endoscopic treatment for moderate to severe AC. METHODS: We enrolled all patients diagnosed with moderate to severe cholangitis due to common bile duct stones from January 2019 to July 2023. The outcomes were compared in this study between patients who underwent ERCP within 24 h and those who underwent ERCP 24 h later, employing a propensity score (PS) framework. Our primary outcomes were intensive care unit (ICU) admission rates, ICU length of stay, and duration of antibiotic use. RESULTS: In total, we included 254 patients and categorized them into two groups based on the time elapsed between admission and intervention: The urgent group (≤ 24 h, n = 102) and the elective group (> 24 h, n = 152). Ninety-three pairs of patients with similar characteristics were selected by PS matching. The urgent ERCP group had more ICU admissions (34.4% vs 21.5%, P = 0.05), shorter ICU stays (3 d vs 9 d, P < 0.001), fewer antibiotic use (6 d vs 9 d, P < 0.001), and shorter hospital stays (9 d vs 18.5 d, P < 0.001). There were no significant differences observed in adverse events, in-hospital mortality, recurrent cholangitis occurrence, 30-d readmission rate or 30-d mortality. CONCLUSION: Urgent one-stage ERCP provides the advantages of a shorter ICU stay, a shorter duration of antibiotic use, and a shorter hospital stay.

The dysregulation of biliary tract microflora is closely related to primary choledocholithiasis: a multicenter study.

Bile microecology changes play an important role in the occurrence and development of choledocholithiasis. At present, there is no clear report on the difference of bile microecology between asymptomatic patients with gallbladder polyps and choledocholithiasis. This study compared bile microecology between gallbladder polyp patients and patients with choledocholithiasis to identify risk factors for primary choledocholithiasis. This study was conducted in 3 hospitals in different regions of China. Bile samples from 26 patients with gallbladder polyps and 31 patients with choledocholithiasis were collected by laparoscopic cholecystectomy and endoscopic retrograde choledocholithiasis cholangiography (ERCP), respectively. The collected samples were used for 16S ribosomal RNA sequencing and liquid chromatography mass spectrometry analysis. The α-diversity of bile microecological colonies was similar between gallbladder polyp and choledocholithiasis, but the ß-diversity was different. Firmicutes, Proteobacteri, Bacteroidota and Actinobacteriota are the most common phyla in the gallbladder polyp group and choledocholithiasis group. However, compared with the gallbladder polyp patients, the abundance of Actinobacteriota has significantly lower in the choledocholithiasis group. At the genera level, the abundance of a variety of bacteria varies between the two groups, and Enterococcus was significantly elevated in choledocholithiasis group. In addition, bile biofilm formation-Pseudomonas aeruginosa was more metabolically active in the choledocholithiasis group, which was closely related to stone formation. The analysis of metabolites showed that a variety of metabolites decreased in the choledocholithiasis group, and the concentration of beta-muricholic acid decreased most significantly. For the first time, our study compared the bile of gallbladder polyp patients with patients with choledocholithiasis, and suggested that the change in the abundance of Actinobacteriota and Enterococcus were closely related to choledocholithiasis. The role of Pseudomonas aeruginosa biofilm in the formation of choledocholithiasis was discovered for the first time, and some prevention schemes for choledocholithiasis were discussed, which has important biological and medical significance.

Clinical application of indocyanine green fluorescence navigation technique in laparoscopic common bile duct exploration for complex hepatolithiasis.

BACKGROUND: This study investigated the clinical application of the indocyanine green (ICG) fluorescence navigation technique in bile duct identification during laparoscopic common bile duct exploration (LCBDE) for complex hepatolithiasis. METHODS: Eighty patients with complex hepatolithiasis were admitted to our department between January 2022 and June 2023 and randomly divided into control and observation groups. The control group underwent conventional LCBDE, while the observation group underwent LCBDE guided by ICG fluorescence. RESULTS: Intraoperatively, the observation group had shorter operation and search times for the common bile duct (CBD), as well as reduced intraoperative blood loss and fewer complications, such as conversion to laparotomy and various injuries (gastroduodenal, colon, pancreatic, and vascular) than the control group, with statistical significance (P < 0.05). Postoperatively, the observation group had lower rates of postoperative bile leakage, abdominal infection, postoperative hemorrhage, and residual stone than the control group. Additionally, the observation group demonstrated significantly shorter times for resuming flatus, removal of the abdominal drainage tube, and hospitalization than the control group, with statistical significance (P < 0.05). CONCLUSION: ICG fluorescence navigation technology effectively visualizes the bile duct, improves its identification rate, shortens the operation time, prevents biliary tract injury, and reduces the occurrence of complications.

Comparative Risks of Post-ERCP Adverse Events in Patients with Asymptomatic and Symptomatic Choledocholithiasis: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the standard of care for the management of choledocholithiasis but carries risk of complications which may result in significant morbidity and mortality. While currently available guidelines endorse the use of ERCP for the management of symptomatic common bile duct stones, the need for ERCP in incidentally found asymptomatic choledocholithiasis is more controversial, and practice varies on a geographic and institutional level. This systematic review and meta-analysis is conducted to compare post-ERCP adverse events between asymptomatic and symptomatic choledocholithiasis patients. METHODS: We searched PubMed/Embase/Web of Science databases to include all studies comparing post-ERCP outcomes between asymptomatic and symptomatic choledocholithiasis patients. The primary outcome was post-ERCP pancreatitis (PEP), while secondary outcomes included post-ERCP cholangitis, bleeding, and perforation. We calculated pooled risk ratios (RR) and 95% confidence intervals (CIs) using the Mantel-Haenszel method within a random-effect model. RESULTS: Our analysis included six observational studies, totaling 2,178 choledocholithiasis patients (392 asymptomatic and 1786 symptomatic); 53% were female. Asymptomatic patients exhibited a higher risk of PEP compared with symptomatic patients (11.7% versus 4.8%; RR 2.59, 95% CI 1.56-4.31, p ≤ 0.001). No significant difference was observed in post-ERCP cholangitis, bleeding, or perforation rates between the two groups. CONCLUSIONS: Asymptomatic patients with choledocholithiasis appear to have a higher risk of PEP than symptomatic patients, while the risk of other post-ERCP adverse events is similar between the two groups. Interventional endoscopists should thoroughly discuss potential adverse events (particularly PEP) with asymptomatic patients before performing ERCP and utilize PEP-prevention measures more liberally in this subgroup of patients.

The value of endoscopic duodenal papilloplasty with titanium clip in improving post-operative complications of choledocholithiasis.

OBJECTIVE: To investigate the value of endoscopic duodenal papillary sphincterotomy combined with balloon dilatation in the treatment of duodenal papilloplasty with titanium clip after choledocholithiasis in post-operative complications. MATERIALS AND METHODS: One hundred and twenty-five patients (69 males and 56 females) with a median age of 65 (32-81) years were included. The treatment plan was randomly divided into Group A (n = 59) and Group B (n = 66) according to the random number table. Patients in Group A were treated with endoscopic sphincterotomy (EST) combined with endoscopic papillary large balloon dilation (EPLBD), followed by a titanium clip for duodenal papilloplasty and then indwelling nasobiliary drainage, whereas those in Group B were treated with EST combined EPLBD to remove stones and then indwelling nasobiliary drainage. RESULTS: In patients with choledocholithiasis or with anatomical changes that make stone extraction difficult, this prospective study attempted to perform duodenal papilloplasty with titanium clips after EST and EPLBD lithotripsy to compare and observe post-operative papillary healing, biliary reflux, and complication rates. CONCLUSIONS: The use of endoscopic duodenal papilloplasty with a titanium clip can improve biliary reflux after lithotripsy and reduce the incidence of post-operative cholangitis complications.

OBJETIVO: Investigar el valor de la esfinterotomía papilar duodenal endoscópica combinada con dilatación con balón en el tratamiento de la papiloplastia duodenal con clip de titanio después de coledocolitiasis en complicaciones postoperatorias. MATERIALES Y MÉTODOS: Se incluyeron un total de 125 pacientes (69 hombres y 56 mujeres) con una mediana de edad de 65 (32-81) años. Los pacientes del Grupo A se trataron con esfinterotomía endoscópica (EST) combinada con dilatación papilar endoscópica con balón grande (EPLBD), seguida de clip de titanio para papiloplastia duodenal y luego drenaje nasobiliar permanente, mientras que los del Grupo B se trataron con EPLBD combinado con EST para eliminar cálculos y luego drenaje nasobiliar permanente. RESULTADOS: En pacientes con coledocolitiasis o con cambios anatómicos que dificultan la extracción de cálculos, este estudio prospectivo intentó realizar papiloplastia duodenal con clips de titanio después de litotricia EST y EPLBD para comparar y observar la cicatrización papilar postoperatoria, el reflujo biliar y las tasas de complicaciones. CONCLUSIÓN: El uso de papiloplastia duodenal endoscópica con clips de titanio puede mejorar el reflujo biliar después de la litotricia y reducir la incidencia de complicaciones de colangitis postoperatorias.

ERCP for common bile duct stones in the elderly: refining the procedure to improve outcomes.

Removal of common bile duct stones in patients with a previous cholecystectomy was one of the first indications for ERCP with biliary sphincterotomy. Thanks to a minimally invasive procedure, patients were prevented from having a new operation. Subsequently, as the technique proved to be successful, ERCP was extended to all patients with choledocholithiasis, regardless of whether or not they had gallbladder. Also contributing was the fact that, at least in the beginnings, surgical interventions on the bile duct with laparoscopic cholecystectomy were more difficult. Nowadays, many surgeons prefer to perform cholecystectomy with a bile duct clean of stones. In this issue of the Spanish Journal of Gastroenterology, Gardenyes et al. present a study on ERCP for common bile duct stones in elderly patients. The novelty of this study is not only to analyze the ERCP procedure, which we already knew has similar success and complication rates to younger patients, but also to focus on the long-term outcome, considering the frailty that frequently accompanies aging. The study concludes that older patients may benefit from enhanced care protocols to reduce medical adverse events and improve outcomes. For us gastroenterologists and endoscopists, another conclusion that can be drawn from this study is that we should not be satisfied that ERCP in older patients has the same success and complication rates as in younger patients, but rather we should strive to ensure that the results are even better.

Comparison of laparoscopic common bile duct exploration plus cholecystectomy and endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy for elderly patients with common bile duct stones and gallbladder stones.

BACKGROUND: Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years. METHODS: A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis. RESULTS: This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]). CONCLUSION: Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

Results during the learning curve in the laparoscopic common bile duct exploration for choledocolithiasis.

OBJECTIVES: To analyze the results obtained in terms of efficacy and safety during the learning curve of a surgical team in the technique of laparoscopic common bile duct exploration with cholecystectomy (LCBDE+LC) using choledochoscopy for the treatment of patients with cholelithiasis and choledocolithiasis or common bile duct stones (CBDS) (CDL). METHODS: Single-center prospective analysis of patients treated with LCBDE+LC during the first 4 years of implementation of the technique. A descriptive and comparative analysis was carried out between groups according to the transcystic (TCi) or transcolecocal (TCo) approach, and also evolutionary by periods. The effectiveness of the technique was evaluated using the variable success rate and safety through the analysis of the overall complication rate and the bile leak rate as the most frequent adverse effect. RESULTS: A total of 78 patients were analyzed. The most frequent approach was TCo (62%). The overall success rate was 92%. The TCi group had a shorter operating time, a lower overall complications rate and a shorter hospital stay. The TCo approach was related to a higher rate of clinically relevant bile leak (8%). Complex cases increased significantly during the learning curve without effect on the overall results. CONCLUSIONS: LCBDE+LC is an effective and safe technique during the learning curve. Its results are comparable to those published by more experienced groups and do not present significant differences related to the evolution during learning period.

Case Report of Overlapping Pyloric Obstruction Due to Dichlorvos Poisoning and Cholelithiasis with Choledocholithiasis.

BACKGROUND Pyloric obstruction after dichlorvos poisoning causes repeated vomiting and inability to eat. Choledocholithiasis and cholelithiasis are the common digestive diseases, with high morbidity and relapse in elderly patients. However, the complex situation of these diseases' coexistence is a clinically intractable problem, and literature on selecting optimal surgical planning is scarce. CASE REPORT A thin 79-year-old woman took dichlorvos due to family conflicts. She improved after being urgently sent to local hospital for gastric lavage and detoxification. Over the next 3 months, she presented with intermittent nausea, vomiting, epigastric pain, and mental apathy, and was readmitted. Gastroscopy showed extensive scarring in the antrum, pyloric obstruction, and gastric retention. Magnetic resonance cholangiopancreatography revealed gallstones and choledocholithiasis. Also, she presented with gastric retention, hypertension, moderate anemia, hypoproteinemia, and electrolyte disturbances. After hospitalization, conservative treatment was performed, without improving vomiting, followed by surgical treatment. Gastrojejunostomy, Braun anastomosis, and nasojejunal feeding tube placement were performed for pyloric stenosis; cholecystectomy for cholelithiasis; and choledochotomy, intraoperative choledochoscopy examination, basket stone extraction, and primary suture of common bile duct without indwelling T tube for choledocholithiasis. Patient recovered and was discharged 9 days after surgery. She was recovered well, without vomiting, at 2-month follow-up. CONCLUSIONS Gastrojejunostomy plus Braun anastomosis is effective treatment of elderly patients with pyloric obstruction formed after pesticide-induced corrosion. Careful selection of choledocholithotomy with primary suture without indwelling T tube reduced postoperative pain and accelerated recovery. This complex case of pyloric obstruction with gallbladder and bile duct stones provides useful considerations for clinical treatment.

Index admission cholecystectomy for biliary acute pancreatitis or choledocholithiasis reduces 30-day readmission rates in children.

BACKGROUND: Adult patients with biliary acute pancreatitis (BAP) or choledocholithiasis who do not undergo cholecystectomy on index admission have worse outcomes. Given the paucity of data on the impact of cholecystectomy during index hospitalization in children, we examined readmission rates among pediatric patients with BAP or choledocholithiasis who underwent index cholecystectomy versus those who did not. METHODS: Retrospective study of children (< 18 years old) admitted with BAP, without infection or necrosis (ICD-10 K85.10), or choledocholithiasis (K80.3x-K80.7x) using the 2018 National Readmission Database (NRD). Exclusion criteria were necrotizing pancreatitis with or without infected necrosis and death during index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmission. RESULTS: In 2018, 1122 children were admitted for index BAP (n = 377, 33.6%) or choledocholithiasis (n = 745, 66.4%). Mean age at admission was 13 (SD 4.2) years; most patients were female (n = 792, 70.6%). Index cholecystectomy was performed in 663 (59.1%) of cases. Thirty-day readmission rate was 10.9% in patients who underwent cholecystectomy during that index admission and 48.8% in those who did not (p < 0.001). In multivariable analysis, patients who underwent index cholecystectomy had lower odds of 30-day readmission than those who did not (OR 0.16, 95% CI 0.11-0.24, p < 0.001). CONCLUSIONS: Index cholecystectomy was performed in only 59% of pediatric patients admitted with BAP or choledocholithiasis but was associated with 84% decreased odds of readmission within 30 days. Current guidelines should be updated to reflect these findings, and future studies should evaluate barriers to index cholecystectomy.
