Objective:To evaluate laparoscopic choledocholithotomy in patients with cholecystolithiasis and normal sized common bile duct(CBD) with choledocholithiasis.Methods:The clinical data of 393 patients with cholecystolithiasis and choledocholithiasis treated by LC combined with LCBDE at the Department of General Surgery of Hefei Second People's Hospital from Mar 2014 to Jul 2021 were retrospectively analyzed.Results:There were 280 CBD calculi cases in which CBD diameter >8 mm which was included into CBD dilated group, and 113 cases of CBD calculi with normal diameter (5 mm≤CBD diameter ≤8 mm). There was no difference in operative time and postoperative complications in the small diameter group. During the follow-up period, 1 case in the dilated group experienced biliary tract stenosis and treated by stenting. There was no statistical significance in biliary tract stenosis in both groups ( P>0.05).Stone recurrence occurred in 3 cases (2.7%) in the normal diameter group, all of which were removed by ERCP lithotomy. Stone recurrence occurred in 8 cases (2.9%) in the CBD dilated group, 7 were removed by ERCP stone extraction and 1 refused further treatment. Conclusion:It is safe and feasible to perform LC+LCBDE in patients with cholecystolithiasis complicating normal sized CBD stones.

Controversias en cirugía: colelitiasis y coledocolitiasis ¿Exploración de vías biliares laparoscópica más colecistectomía laparoscópica (cirugía en un paso) o CPRE y colecistectomía laparoscópica (cirugía en dos pasos)? / Controversies in surgery: Cholelithiasis and choledocholithiasis - Laparoscopic bile duct exploration plus laparoscopic cholecystectomy (one-step surgery) or ERCP and laparoscopic cholecystectomy(two-step surgery)?

Introducción. La colelitiasis tiene una prevalencia del 15 % y el 21 % tendrá coledocolitiasis al momento de la colecistectomía, con 50 % de probabilidad de presentar complicaciones asociadas. Desde el advenimiento de la colecistectomía laparoscópica, el abordaje de la coledocolitiasis ha sido endoscópico, usualmente en un tiempo diferente al vesicular, sin embargo, los avances en laparoscopia han permitido explorar la vía biliar común por la misma vía, pudiendo realizar ambos procedimientos en el mismo tiempo de forma segura. Métodos. Se realizó una búsqueda de la literatura existente con relación al enfoque para el manejo de la colecisto-coledocolitasis en un paso comparado con dos pasos. Resultados. Existe evidencia que demuestra mayor efectividad del abordaje en dos pasos, con CPRE y posterior colecistectomía laparoscópica, sobre el abordaje en un paso, especialmente en la tasa de fuga biliar y de cálculos retenidos. El enfoque en un paso con exploración de vías biliares y colecistectomía laparoscópica en el mismo tiempo es seguro, con alta tasa de éxito, baja incidencia de complicaciones, menor estancia hospitalaria y costos. Conclusión. El abordaje laparoscópico en un solo paso es un procedimiento seguro y eficaz para el manejo de la colecisto-coledocolitiasis, con el beneficio de estancia hospitalaria menor, sin embargo, se requieren habilidades técnicas avanzadas en cirugía laparoscópica. En nuestro medio ya existe una infraestructura para el manejo híbrido con CPRE y colecistectomía laparoscópica, pudiéndose realizar ambos en el mismo tiempo, para reducir estancia y costos.

Introduction. Cholelithiasis has a prevalence of 15%, and 21% will have choledocholithiasis at the time of cholecystectomy, with a 50% probability of presenting associated complications. Since the advent of laparoscopic cholecystectomy, the approach to choledocholithiasis has been endoscopic, normative at a different time than the gallbladder; however, advances in laparoscopy have made it possible to explore the common bile duct by the same route, being able to perform both procedures in a single time safely. Methods. A search of the existing literature was performed regarding the one-step approach compared to the two-step approach for the management of cholelithiasis and choledocholithiasis. Results. There is evidence that demonstrates greater effectiveness of the two-step approach with ERCP and subsequent laparoscopic cholecystectomy over the one-step approach, especially in the rate of bile leak and the incidence of retained stones. The one-step approach with bile duct exploration and laparoscopic cholecystectomy at the same time is safe, with a high success rate, low incidence of complications, shorter hospital stay, and lower costs. Conclusion. The one-step laparoscopic approach is a safe and effective procedure for the management cholelithiasis and concomitant choledocholithiasis, with the benefit of a shorter hospital stay; however, advanced technical skills in laparoscopic surgery are required. In our environment there is already an infrastructure for hybrid management with ERCP and laparoscopic cholecystectomy, both of which can be performed at the same time to reduce hospital stay and costs.

Abordaje laparoscópico sistemático de la coledocolitiasis / Routine laparoscopic management of common bile duct stones

RESUMEN Antecedentes: la prevalencia conjunta de litiasis vesicular y coledociana aumenta con la edad y llega al 15% en la octava década de la vida. Su manejo continúa siendo controvertido: algunos profesionales prefieren el abordaje en un tiempo por videolaparoscopia, y otros, el abordaje en dos tiempos con endoscopia (CPRE preoperatoria) seguida de colecistectomía laparoscópica. Objetivo: evaluar la eficacia y seguridad del manejo en un tiempo por videolaparoscopia en pacientes consecutivos con diagnóstico de litiasis vesicular y coledociana. Material y métodos: estudio retrospectivo con datos de una base de datos prospectiva, entre julio de 2008 y julio de 2018. Resultados: sobre un total de 2447 colecistectomías laparoscópicas realizadas en el citado período, 416 (17%) presentaron litiasis coledociana. El éxito global de la vía transcística en la extracción de litiasis coledociana fue del 81,2%: del 70,4% en los casos con diagnóstico prequirúrgico de colestasis extrahepática litiásica y del 92,9% en los otros diagnósticos. La morbilidad fue del 4%, sin mortalidad ni lesiones quirúrgicas de la vía biliar. Conclusión : el manejo en un tiempo por videolaparoscopia es eficaz y seguro debido al elevado éxito global de la instrumentación transcística (ITC). El diagnóstico preoperatorio de coledocolitiasis condi ciona una disminución de esa eficacia, por mayor indicación de coledocotomía, con un aumento de la morbilidad y del tiempo de internación.

ABSTRACT Background: The prevalence of common bile duct stones associated with cholelithiasis increases with age and is about 15 % in the 8th decade of life but its management is still controversial. Some surgeons prefer the single-stage approach with laparoscopy while others suggest the two-stage management with preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy. Objective: The aim of the present study was to evaluate the efficacy of feasibility of single-stage laparoscopic surgery in patients with cholelithiasis and choledocholithiasis. Material and methods: We conducted a retrospective study with prospectively collected data between July 2008 and July 2018. Results: Of 2447 laparoscopic cholecystectomies performed during the study period, 416 presented common bile duct stones. The global success of the transcystic approach to clear common bile duct stones was 81.2%, 70.4% in the cases with preoperative diagnosis of choledocholithiasis and 92.9% for other diagnoses. The rate of complications was 4% without deaths or bile duct injuries. Conclusion: Single-stage laparoscopic surgery is an efficient and safe approach based on the high global success of transcystic exploration. The preoperative diagnosis of choledocholithiasis reduces the efficacy of the procedure due to greater indication of choledocotomy, with complications and longer length of hospital stay.

Effect of laparoscopic cholecystectomy combined with laparoscopic common bile duct exploration on pain stress and inflammatory factors in elderly patients with cholecystolithiasis and choledocholithiasis / 国际外科学杂志

Objective:To investigate the effect of laparoscopic cholecystectomy (LC) combined with common bile duct exploration (LCBDE) on pain stress and inflammatory factors in elderly patients with gallbladder stones and common bile duct stones.Methods:Eighty elderly patients with cholecystolithiasis and choledocholithiasis in Huadong Hospital Affiliated to Fudan University from January 2020 to January 2021 were selected. According to the surgical method, they were divided into observation group of 40 cases and control group of 40 cases. Patients in the observation group were treated with LC combined with LCBDE, and patients in the control group were treated with traditional open surgery. The perioperative indicators and complications, changes in pain stress and inflammatory factors before and 3 days after operation, and the quality of life before operation, 1 month after operation and 6 months after operation were compared between the two groups. Normally distributed measurement data were represented by mean±standard deviation ( Mean± SD), and t test was used to compare between groups. The chi-square test was used to compare the count data between groups. Results:The operation time, time to get out of bed, postoperative exhaust time, intraoperative blood loss, and postoperative complications in the observation group were (98.39±7.23) min, (1.56±0.37) d, (1.29±0.28) d, (38.94±5.64) mL, 5%, the control group were (107.53±9.98) min, (2.53±0.52) d, (2.16±0.34) d, (65.87±7.96) mL, 25%, the observation group were excellent in all indicators compared with the control group, the differences between the two groups were statistically significant ( P<0.05). After operation 3rd day, the serum 5-hydroxytryptamine, substance P and norepinephrine in the two groups were higher than before operation ( P<0.05); after operation 3rd day, serum 5-hydroxytryptamine, substance P and norepinephrine the observation group were (0.70±0.12) pg/mL, (175.42±17.87) ng/mL and (378.52±26.57) ng/mL, the control group were (1.02±0.18) pg/mL, (248.98±18.98) ng/mL, and (460.92±35.42) ng/mL. The indexes of the observation group were smaller than those of the control group, the differences between the two groups were statistically significant ( P<0.05). After operation 3rd day, the serum tumor necrosis factor-α, C-reactive protein and interleukin-6 in the two groups were higher than before operation ( P<0.05); after operation 3rd day, Serum tumor necrosis factor-α, C-reactive protein and interleukin-6 in the observation group were (108.76±10.86) pg/mL, (14.23±3.18) mg/L and (17.84±3.98) pg/mL, respectively, on the 3rd day after operation. The control group were (156.95±16.67) pg/mL, (26.52±4.59) mg/L and (28.53±5.67) pg/mL, the observation group indexes were all smaller than control group, the differences between the two groups were statistically significant ( P<0.05). The quality of life scores of the two groups at 1 month and 6 months after the operation were higher than before operation ( P<0.05); The quality of life scores of patients in the observation group at 1 month and 6 months after surgery were higher than control group ( P<0.05). Conclusion:LC combined with LCBDE treatment has little effect on pain stress and inflammatory factors in elderly patients with cholecystolithiasis and choledocholithiasis, and has fewer postoperative complications, and can improve the quality of life of patients.

Objective:To introduce the usefulness and advantages of needle-type choledochotomy in laparoscopic common bile duct exploration.Methods:A retrospective analysis for the data of 1 107 patients who successfully implemented laparoscopic common bile duct exploration in Subei People′s Hospital of Jiangsu Province from January 1, 2013 to December 31, 2020 were applied. All cases were divided into the study group 662 cases with needle-type choledochotomy) and the control group (445 cases with non-needle-type choledochotomy) according to the manipulation of common bile duct incision. The time-cost, incidences of bleeding and bile leakage, as well as the recurrence rate of bile duct stone and the incidence of bile duct stenosis were observed and compared between the two groups. Normally distributed data were expressed as mean±standard deviation ( Mean± SD) and compared by t test while count data were expressed as frequency or percentage and compared by chi-square test or Fisher′s exact test. Results:The bile duct incision time and bleeding rate were (14.45±2.46) s and 25.1% in the study group, (104.48±15.32) s and 68.1% in the control group, respectively. The differences between the two groups were statistically significant ( P<0.001). The incidence of stone recurrence, biliary leakage, and bile duct stricture were 3.0%, 3.6% and 0.3% in the study group, 4.9%, 5.6% and 0.4% in the control group, respectively. There were no statistically significant differences between the two groups ( P>0.05). Conclusion:Needle-type bile duct incision can be used as a routine manipulation in laparoscopic common bile duct exploration for its time-saving, less bleeding, safe and easy to handling.

Exploración laparoscópica de las vías biliares. Descripción de la técnica paso a paso. Video / Laparoscopic exploration of the bile ducts. Description of the technique step by step. Video

La exploración laparoscópica de las vías biliares (ELVB) constituye, hoy en día, una herramienta de gran utilidad en el tratamiento de la patología litiásica del árbol biliar, especialmente cuando técnicamente sea imposible realizar una pancreato-colangiografía retrógrada endoscópica (PCRE) o en los casos en los cuales este estudio no esté disponible. Método: Describir mediante un video nuestra técnica de ELVB paso a paso, en una paciente de 41 años quien consultó por presentar tinte ictérico en piel y mucosas, coluria e hipocolia. El ultrasonido abdominal reportó litiasis vesicular, dilatación de vías biliares intra y extra hepáticas, colédoco de 9 mm de diámetro y múltiples imágenes hiperecogénicas sugestivas de litiasis. Al no poder realizarse PCRE se decide practicar ELVB. Se realizó disección del triángulo biliocístico, identificación y ligadura proximal del conducto cístico con la finalidad de evitar la migración de cálculos a la vía biliar durante el procedimiento, coledocotomía, lavado proximal y distal de la vía biliar, exploración con catéter de Fogarty, coledocorrafia primaria, cisticotomía y colocación de catéter para colangiografía intraoperatoria, constatación de plenificación de las vías biliares sin imágenes de defecto y de adecuado paso del contraste al duodeno, colecistectomía y colocación de drenaje subhepático. Resultados: Paciente evoluciona en forma satisfactoria, egresando al tercer día de postoperatorio sin eventualidades. Discusión: La ELVB con coledocorrafia primaria ha sido descrita como una alternativa viable y efectiva para el manejo de la litiasis biliar, destacando su menor morbimortalidad cuando se compara con procedimientos endoscópicos como la PCRE(AU)

Laparoscopic common bile duct exploration (LCBDE) constitutes, nowadays, a very useful tool in the treatment of biliary tree lithiasis, especially when it is technically impossible to perform an endoscopic retrograde pancreatic cholangiography (ERCP) or in cases when this study is not available. Method: Using a video, we describe our LCBDE technique step by step, in a 41-year-old patient who consulted for presenting jaundiced skin and mucosa, coluria and hypocolia. Abdominal ultrasound reported gallstones, intra- and extra-hepatic bile duct dilation, a 9-mm diameter common bile duct (CBD) and multiple hyperechoic images suggestive of lithiasis. Since ERCP could not be performed, it was decided to practice LCBDE. Dissection of the Calot's triangle was performed, identification and proximal ligation of the cystic duct in order to avoid migration of stones to the common bile duct during the procedure, choledochotomy, proximal and distal lavage of the bile duct, exploration with a Fogarty catheter, primary closure of CBD, cysticotomy and placement of catheter for intraoperative cholangiography, verification of fullness of the bile ducts without defect images and adequate passage of contrast to the duodenum, cholecystectomy and placement of subhepatic drainage. Results: Patient progressed satisfactorily, being discharged on the third postoperative day, uneventfully. Discussion: LCBDE with primary closure of CBD has been described as a viable and effective alternative for the management of biliary stones, highlighting its lower morbidity and mortality when compared with endoscopic procedures such as ERCP(AU)

Innovative hybrid technique for bile duct exploration in the treatment of choledocholithiasis

Introduction: Common bile stone disease (CBDS) is frequent and has potentially severe complications, such as acute biliary pancreatitis and cholangitis. Unnecessary and unplanned procedures should be avoided, so before choosing the best treatment of common bile duct lithiasis it is essential to have a proper diagnose. CBDS is currently treated by therapeutic endoscopic retrograde cholangiopancreatography (ERCP) or laparoscopic bile duct exploration (LCBDE). Results: The aim of this article is to present an innovative hybrid technique for common bile duct exploration, as an option for cases where the laparoscopic approach is not resolutive, avoiding the need for conversion to open approach technique. Conclusions: The hybrid technique has the same benefits as open and laparoscopic techniques, but without increasing material costs and with good resolution in complex cases of common bile duct stones.

Current status and progress of laparoscopic common bile duct exploration in the treatment of choledocholithiasis / 中华消化外科杂志

Most of choledocholithiasis is secondary to gallbladder stone,and surgery remains the main treatment mode.In recent years,with the continuous improvement of minimally invasive techniques,the treatment of choledocholithiasis has changed from the traditional open surgery to laparoscopic common bile duct exploration (LCBDE).LCBDE has been widely carried out based on the advantages of small damage,rapid postoperative recovery and few complications.Two methods of LCBDE include through cystic duct and through common bile duct,although through cystic duct LCBDE has smaller damage,application range is narrow.Compared with T-tube drainage,primary suture of common bile duct after LCBDE has less effects on the body and is being promoted gradually.The application of barbed stitches in laparoscopic common bile duct suture has attracted increasing attention.This article reviews the current status and progress of LCBDE in the treatment of choledocholithiasis.
