RESUMEN

INTRODUCTION: An isolated bile leakage is a relatively rare type of postoperative bile leakage. Most isolated bile leakages require invasive procedures such as surgical approaches. PRESENTATION OF CASES: The right hepatic duct was intraoperatively injured during right anterior sectionectomy. Bile leakage occurred postoperatively in the injured bile duct, although the injured bile duct was repaired with suturing and C-tube drainage was performed to decompress the bile duct during hepatectomy. Unfortunately, nonsurgical treatment was not possible. Therefore, bilio-enteric anastomosis between the right hepatic duct and jejunum was ultimately performed because of the small remnant liver volume and poor liver function. DISCUSSION: Bilio-enteric anastomosis can avoid sacrificing functioning liver parenchyma, but in cases of hepatocellular carcinoma recurrence, transarterial chemoembolization carries a high risk of liver abscess due to cholangitis in patients undergoing enteric revision. Liver resection or bilio-enteric anastomosis should be carefully selected based on clinical data, such as remnant liver volume, liver function, and primary liver disease. CONCLUSION: We report a case of isolated bile leakage after anterior sectionectomy for hepatocellular carcinoma that was managed with Roux-en-Y hepaticojejunostomy at the injured right hepatic duct.

RESUMEN

This case report highlights the management of complications from an open abdomen following surgery for ovarian mucinous adenocarcinoma, a rare subtype of ovarian cancer. A 63-year-old female underwent extensive surgery, including single-port laparoscopic total bilateral salpingo-oophorectomy, right hemicolectomy, small bowel resection, cholecystectomy, and jejunostomy. Postoperatively, she experienced bile leakage, leading to significant skin and fascial damage and an abdominal skin defect. Early detection and multidisciplinary management were crucial. Treatment involved vacuum-assisted closure dressing, repeated debridement, and closure of the open abdomen with a local flap. This case emphasizes the complexities of managing ovarian mucinous adenocarcinoma and the critical role of a multidisciplinary approach in treating postoperative complications, underscoring the importance of vigilant postoperative care and timely intervention.

RESUMEN

Background: Celiac axis stenosis can potentially lead to insufficient blood supply to vital organs, such as the liver, spleen, pancreas, and stomach. This condition result in the development of collateral circulation between the superior mesenteric artery and the hepatic artery. However, these collateral circulations are often disrupted during pancreaticoduodenectomy (PD), which may increase the risk of postoperative complications. Methods: A retrospective analysis was conducted on patients who underwent laparoscopic pancreaticoduodenectomy (LPD) from April 2015 to April 2023. Celiac trunk stenosis is classified according to the degree of stenosis: no stenosis (<30%), grade A (30%-<50%), grade B (50%-≤80%), and grade C (>80%). The incidence of postoperative complications was evaluated, and both univariate and multivariate risk analyses were conducted. Results: A total of 997 patients were included in the study, with mild celiac axis stenosis present in 23 (2.3%) patients, moderate stenosis in 18 (1.8%) patients, and severe stenosis in 10 (1.0%) patients. Independent risk factors for the development of bile leakage, as identified by both univariate and multivariate analyses, included body mass index (BMI) (HR = 1.108, 95% CI = 1.008-1.218, P = .033), intra-abdominal infection (HR = 2.607, 95% CI = 1.308-5.196, P = .006), postoperative hemorrhage (HR = 4.510, 95% CI = 2.048-9.930, P = <0.001), and celiac axis stenosis (50%-≤80%, HR = 4.235, 95% CI = 1.153-15.558, P = .030), and (>80%, HR = 4.728, 95% CI = .882-25.341, P = .047). Celiac axis stenosis, however, was not determined to be an independent risk factor for pancreatic fistula (P > 0.05). Additionally, the presence of an aberrant hepatic artery did not significantly increase the risk of postoperative complications when compared with celiac axis stenosis alone. Conclusion: Severe celiac axis stenosis is an independent risk factor for postoperative bile leakage following LPD.

RESUMEN

PURPOSE: Prophylactic drains reported to be useful to treat postoperative bile leakage (POBL) and reduce re-intervention after hepatectomy. However, prophylactic drains should remove in the early postoperative period. This study aimed to assess the association between postoperative complications and the drain-fluid data on postoperative day (POD) 1. METHODS: Medical records of 530 patients who underwent hepatectomy were retrospectively reviewed. We evaluated the drain-fluid data on POD 1, such as bilirubin (BIL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and drain discharge volume. These variables were compared between patients with and without postoperative complications such as POBL and abdominal abscess not due to POBL. RESULTS: POBL was found in 44 patients (8.3%), PHLF was in 51 patients (9.6%), and abdominal abscess not due to POBL was in 21 patients (4.0%). Regarding POBL, drain-fluid BIL concentration and drain discharge volume was higher in the POBL group (p < 0.001 and p < 0.001, respectively). However, drain-fluid AST, ALT, and ALP concentrations were not different between two groups. As to the abdominal abscess not due to POBL, all drain-fluid data were not significantly different. Multivariate analysis for predicting POBL showed that the drain-fluid BIL concentration ≥ 2.68 mg/dL was an independent predictor (p < 0.001). In the subgroup analyses according to the type of hepatectomy, the drain-fluid BIL concentration was an independent predictor for POBL after both non-anatomical and anatomical hepatectomy. CONCLUSION: The drain-fluid BIL concentration on POD 1 is useful in predicting POBL after hepatectomy.

RESUMEN

Objective: Our aim was to present the results of endoscopic retrograde cholangiopancreatography (ERCP) after living donor liver transplantation (LDLT) between February 2015 and June 2021. Methods: Clinical data included LDLT indications, time to perform ERCP after LDLT, number of ERCP procedures, indications for ERCP, and all treatment outcomes, including ERCP, percutaneous, and surgical interventions. We compared the obtained data with our previous study published by our team in 2018, which included 446 patients who underwent ERCP for biliary complications after LDLT between 2005 and 2015. Results: We performed ERCP in 283 of 1506 patients with LDLT who underwent duct-to-duct anastomosis during transplantation and then developed biliary complications. Our endoscopic success rates were 60.9% and 71.0% in the previous and present studies, respectively. Conclusions: Our findings suggest that the success rate of endoscopic treatment of biliary complications in patients with LDLT increases in correlation with the increasing experience of clinicians treating these patients.

RESUMEN

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.

RESUMEN

We report a case of a male patient who presented with multiple abdominal and pelvic echinococcosis. The patient had been diagnosed with hepatic echinococcosis for 7 years and developed intermittent distension and discomfort in the upper abdomen after an accidental fall. In recent years, the patient's abdominal distention increased gradually. Computed tomography revealed multiple hydatid cysts in the liver, spleen, abdominal cavity, and pelvic cavity. Abdominal organs were severely compressed, such that he could not eat normally except for a liquid diet. The patient underwent radical surgical resection based on the multi-disciplinary treatment (MDT) and the operation lasted 10 h, nearly 100 hydatid cysts were excised, about 18 liters of cyst fluid and cyst contents were removed, and the patient lost 20 kg of weight after surgery. The operation was successful, but there were still some postoperative complications such as hypovolemic shock, postoperative ascites, postoperative bile leakage. Treatment measures for the patient were anti-infection, antishock, clamping the abdominal drainage tube, and negative pressure abdominal puncture drainage. At follow up the patient's quality of life had been significantly improved with 15 kg weight gain compared to before.

RESUMEN

Objective:To analyze the clinical value of indocyanine green (ICC) fluorescence imaging in Mirizzi syndrome type Ⅱ-Ⅲ laparoscopic cholecystectomy (LC).Methods:A retrospective analysis was performed on 80 patients diagnosed with Mirizzi syndrome types Ⅱ-Ⅲ who underdoing LC in Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from October 2018 to February 2022, including 32 males and 48 females, aged (63.5±6.9) years. Patients were divided into two groups based on whether ICG fluorescence imaging technology was used, the control group ( n=38) that patients were treated with conventional LC and the experimental group ( n=42) patients were treated with LC guided by ICG fluorescence imaging. In the experimental group, the extrahepatic bile duct was identified by ICG fluorescence imaging during LC, and ICG was injected intraoperally to determine the reserved blood flow of gallbladder flap for fluorescence imaging and determine the resection line. Operation time, intraoperative blood loss, conversion rate of laparotomy and postoperative complications (bile leakage, incision infection, etc.) were compared between the two groups. Intraoperative fluorescence imaging and determination of the modified resection line of reserved gallbladder were analyzed in the observation group. Results:There was no significant difference in age, male proportion, type of Mirizzi syndrome and conversion rate of laparotomy between the two groups (all P>0.05). In the observation group, the operative time was (208.7±32.0) min, the intraoperative blood loss was (50.5±23.8) ml, and the biliary leakage was 7.1% (3/42), which was lower than that in the control group (228.2±33.9) min, (73.8±31.0) ml, 26.3% (10/38). The differences were statistically significant (all P<0.05). Of 37 cases (88%) showed common hepatic duct and common bile duct successfully in the observation group. In the observation group, ICG fluorescence imaging was used to determine the gallbladder resection line in 8 cases (19.0%). The gallbladder flap without fluorescence imaging was removed. Conclusion:ICG fluorescence imaging in LC for Mirizzi syndrome patients can identify the common bile duct and hepatic duct to guide surgical resection, determine the gallbladder flap resection line, reduce postoperative bile leakage and bleeding, and accelerate the surgical progress.

RESUMEN

In recent years, with the development of organ preservation, surgical techniques, perioperative management and immunosuppression regimens, the success rate of liver transplantation and survival rate of the recipients have been significantly enhanced. Liver transplantation has become the optimal treatment for patients with end-stage liver disease. However, biliary complications still commonly occur after liver transplantation, especially biliary anastomotic stricture. Severe biliary anastomotic stricture will not only increase the cost of treatment, but also lead to graft loss and even affect the survival rate of recipients. Therefore, timely diagnosis and treatment of biliary anastomotic stricture play a significant role in improving the survival rate of liver transplant recipients. In this article, the risk factors, clinical symptoms, diagnosis and treatment of biliary anastomotic stricture after liver transplantation were reviewed, aiming to provide novel ideas for the research, diagnosis and treatment of biliary anastomotic stricture after liver transplantation, and further enhance clinical efficacy of liver transplantation and the quality of life of recipients.

RESUMEN

BACKGROUND: For patients with choledocholithiasis, laparoscopic common bile duct exploration (LCBDE) is preferred over open surgery. Whether primary closure of the common bile duct (CBD) should be performed upon completion of choledochotomy remains unclear, and the corresponding indications for primary closure of the common bile duct have yet to be fully identified. This study was performed to evaluate the safety and feasibility of primary closure of CBD among elderly patients (≥ 70 years) after LCBDE. METHODS: Patients with choledocholithiasis who had undergone LCBDE with primary closure of the CBD between July 2014 and December 2020 were retrospectively reviewed. Included patients were assigned into two groups (Group A: ≥70 years and Group B: <70 years) according to age. Group A was compared with Group B in terms of preoperative characteristics, intraoperative results and postoperative outcomes. RESULTS: The mean operative time for Group A was 176.59 min (± 68.950), while the mean operative time for Group B was 167.64 min (± 69.635) (P = 0.324). The mean hospital stay after surgery for Group A was 8.43 days (± 4.440), while that for Group B was 8.30 days (± 5.203) (P = 0.849). Three patients in Group A experienced bile leakage, while bile leakage occurred in 10 patients in Group B (3.8% vs. 4.5%, P = 0.781). Group A was not significantly different from Group B in terms of postoperative complications and 30-day mortality except pneumonia (P = 0.016), acute cardiovascular event (P = 0.005) and ICU observation (P = 0.037). After a median follow-up time of 60 months, 2 patients in Group A and 2 patients in Group B experienced stone recurrence (2.5% vs. 0.9%, P = 0.612). One patient in Group A experienced stenosis of the CBD, while stenosis of the CBD occurred in 5 patients in Group B (1.3% vs. 2.2%, P = 0.937). CONCLUSIONS: Primary closure of CBD upon completion of LCBDE could be safely performed among patients ≥ 70 years.

RESUMEN

OBJECTIVE: Postoperative bile leakage (POBL) is one of the most common complications after liver resection. However, current studies on the risk factors for POBL and their impacts on surgical outcomes need to be more consistent. This study aims to conduct a meta-analysis to analyze the risk factors for POBL after hepatectomy. METHODS: We incorporated all eligible studies from Embase, PubMed, and the Web of Science database (until July 2022) into this study. RevMan and STATA software were used to analyze the extracted data. RESULTS: A total of 39 studies, including 43,824 patients, were included in this meta-analysis. We found that gender, partial hepatectomy, repeat of hepatectomy, extended hepatectomy, abdominal drain, diabetes, Child≥B, solitary tumor, and chemotherapy are the factors of grade B and C POBL. Some recognized risk factors were considered potential risk factors for grade B and C bile leakage because no subgroup analysis was performed, like HCC, cholangiocarcinoma, major resection, posterior sectionectomy, bi-segmentectomy, S4 involved, S8 involved, central hepatectomy, and bile duct resection/reconstruction. Meanwhile, cirrhosis, benign diseases, left hepatectomy, and Segment 1 resection were not significant for grade B and C bile leakage. The influence of lateral sectionectomy, anterior sectionectomy, S1 involved, S3 involved, high-risk procedure, laparoscope, and blood loss>1000 mL on POBL of ISGLS needs further research. Meanwhile, POBL significantly influenced overall survival (OS) after liver resection. CONCLUSIONS: We identified several risk factors for POBL after hepatectomy, which could prompt the clinician to decrease POBL rates and make more beneficial decisions for patients who underwent the hepatectomy.

RESUMEN

BACKGROUND: The cystic duct tube (C-tube) was used to reduce bile leakage (BL) incidence after hepatectomy. Nevertheless, delayed BL is sometimes experienced even using C-tube. This study investigates the impact of C-tube use on the onset time of post-hepatectomy BL. METHODS: Data from 455 consecutive patients who underwent hepatectomy without biliary reconstruction between November 2007 and July 2020 were analyzed retrospectively. A C-tube was used for intraoperative biliary injury or in consideration of BL risk. BL was divided into two groups according to the postoperative onset time: early onset and late onset. To assess the association between C-tube use and BL, propensity score matching in a 1:1 ratio was performed to match BL risk factors between the C-tube and no-C-tube groups. RESULTS: BL occurred in 30 (6.6%) of the 455 included patients. C-tubes were used in 51 patients (11.2%) with open hepatectomy, high-risk hepatectomy, massive blood loss, long operation time, or prophylactic drain placement. After propensity score matching, BL occurred in 17 of 102 patients (16.7%). Early-onset BL occurred significantly less frequently in the C-tube group than in the no-C-tube group (3.9% vs. 15.7%, p = 0.046); however, late-onset BL was more common in the C-tube group (9.8% vs. 3.9%, p = 0.24). Six of seven patients (85.7%) with BL with C-tube use developed BL after C-tube removal. CONCLUSION: C-tube drainage may reduce early-onset BL in cases having risk factors for BL. Conversely, since late-onset BL often occurs after C-tube removal, attention should be paid to those cases.

RESUMEN

Aim: To summarize systematically our six-year experience in the surgical treatment of postoperative bile leakage after liver tumor surgery in children, and explore its reoperation approach and treatment effect. Methods: The clinical data of 6 patients with postoperative bile leakage cured by surgery from January 2016 to January 2022 were reviewed retrospectively. Results: Among the six pediatric patients with postoperative bile leakage cured by surgery, four were male (67%) and two were female (33%). All patients underwent complex segmentectomy. The median time to bile leakage was 14 days (range, 10 to 32), and the daily drainage volume was stable from 170 ml to 530 ml per day. After conservative treatment failed, four patients received biliary-enteric anastomosis (patients 1, 3, 4, and 6), and two patients received bilio-cholecyst anastomosis (patients 2 and 5). All six patients were successfully treated with reoperation, and five patients were alive and without recurrence, while one patient was lost to follow-up due to abandoned treatment. Conclusion: Our study suggests that surgery is a reliable and effective treatment for postoperative intractable bile leakage in children undergoing complex segmentectomy. Bilioenteric anastomosis is the most common technique for bile leakage, and bilio-cholecyst anastomosis is a feasible and effective surgical approach. These findings have important implications for the management of postoperative complications in pediatric patients undergoing complex segmentectomy.

RESUMEN

Herein, we report two cases of successful application of indocyanine green (ICG) fluorescence imaging for detecting intraoperative bile leakage during laparoscopic cholecystectomy (LC). Bile leakage was detected rapidly and accurately using fluorescence guidance. Based on our findings, we recommend using ICG fluorescence imaging during LC because it is effective and feasible for detecting intraoperative bile leakage.

RESUMEN

A biloma is a loculated, extrahepatic, intra-abdominal bile collection. It is an unusual condition with an incidence of 0.3-2% and is usually a result of choledocholithiasis, iatrogenic injury or abdominal trauma causing disruption to the biliary tree. Rarely, it will occur spontaneously, resulting in spontaneous bile leak. We herein present a rare case of biloma as a complication of endoscopic retrograde cholangiopancreatography (ERCP). A 54-year-old patient experienced right upper quadrant discomfort, following ERCP, endoscopic biliary sphincterotomy and stenting for choledocholithiasis. Initial abdominal ultrasound and computed tomography revealed an intrahepatic collection. Percutaneous aspiration under ultrasound guidance of yellow-green fluid confirmed the diagnosis, indicated infection and contributed to effective management. Most likely, a distal branch of the biliary tree was injured during the insertion of the guidewire through the common bile duct. Magnetic resonance image/magnetic resonance cholangiopancreatography contributed in the diagnosis of two seperate bilomas. Even though post ERCP biloma is an unusual complication, differential diagnosis of patients with right upper quadrant discomfort following an iatrogenic or traumatic event should always include biliary tree disruption. A combination of radiological imaging for diagnosis and minimal invasive technique to manage a biloma can prove to be successful.

RESUMEN

BACKGROUND: This study aims to clarify the perioperative risk factors and short-term prognosis of central bisectionectomy (CB) for hepatocellular carcinoma (HCC). METHODS: Surgical data from 142 selected patients out of 171 HCC patients who underwent anatomical CB (H458) between 2005 and 2020 were collected from 17 expert institutions in a single-arm retrospective study. RESULTS: Morbidities recorded by the International Study Group of Liver Surgery (ISGLS) from grade BC post-hepatectomy liver failure (PHLF) and bile leakage (PHBL), or complications requiring intervention were observed in 37% of patients. A multivariate analysis showed that increased blood loss (iBL) > 1500 mL from PHLF (risk ratio [RR]: 2.79), albumin level < 4 g/dL for PHBL (RR, 2.99), involvement of segment 1, a large size > 6 cm, or compression of the hepatic venous confluence or cava by HCC for all severe complications (RR: 5.67, 3.75, 6.51, and 8.95, respectively) (p < 0.05) were significant parameters. Four patients (3%) died from PHLF. HCC recurred in 50% of 138 surviving patients. The three-year recurrence-free and overall survival rates were 48% and 81%, respectively. CONCLUSIONS: Large tumor size and surrounding tumor involvement, or compression of major vasculatures and the related iBL > 1500 mL were independent risk factors for severe morbidities in patients with HCC undergoing CB.

RESUMEN

PURPOSE: The International Study Group of Liver Surgery (ISGLS) defined post-hepatectomy biliary leakage as drain/serum bilirubin ratio > 3 at day 3 or the interventional/surgical revision due to biliary peritonitis. We investigated the definition's applicability. METHODS: A retrospective evaluation of all liver resections over a 6-year period was performed. ROC analyses were performed for drain/serum bilirubin ratios on days 1, 2, and 3 including grade A to C (analysis I) and grade B and C biliary leakages (analysis II) to test specific cutoff values. RESULTS: A total of 576 patients were included. One hundred nine (18.9%) postoperative bile leakages occurred (19.6% of the whole population grade A, 16.5% grade B/C). Areas under the curve (AUC) for analysis I were 0.841 (day 1), 0.846 (day 2), and 0.734 (day 3). The highest sensitivity (78% on day 1/77% on day 2) and specificity (78% on day 1/79% on day 2) in analysis I were obtained for a drain/serum bilirubin ratio of 2.0. AUCs for analysis II were similar: 0.788 (day 1), 0.791 (day 2), and 0.650 (day 3). The highest sensitivity (73% on day 1/71% on day 2) and specificity (74% on day 1/76% on day 2) in analysis II were detected for a drain/serum bilirubin ratio of 2.0 on postoperative day 2. CONCLUSION: Biliary leakages should be defined if the drain/serum bilirubin ratio is > 2.0 on postoperative day 2.

RESUMEN

BACKGROUND: Pancreaticoduodenectomy is the first choice surgical intervention for the radical treatment of pancreatic tumors. However, an anastomotic fistula is a common complication after pancreaticoduodenectomy with a high mortality rate. With the development of minimally invasive surgery, open pancreaticoduodenectomy (OPD), laparoscopic pancreaticoduodenectomy (LPD), and robotic pancreaticoduodenectomy (RPD) are gaining interest. But the impact of these surgical methods on the risk of anastomosis has not been confirmed. Therefore, we aimed to integrate relevant clinical studies and explore the effects of these three surgical methods on the occurrence of anastomotic fistula after pancreaticoduodenectomy. METHODS: A systematic literature search was conducted for studies reporting the RPD, LPD, and OPD. Network meta-analysis of postoperative anastomotic fistula (Pancreatic fistula, biliary leakage, gastrointestinal fistula) was performed. RESULTS: Sixty-five studies including 10,026 patients were included in the network meta-analysis. The rank of risk probability of pancreatic fistula for RPD (0.00) was better than LPD (0.37) and OPD (0.62). Thus, the analysis suggests the rank of risk of the postoperative pancreatic fistula for RPD, LPD, and OPD. The rank of risk probability for biliary leakage was similar for RPD (0.15) and LPD (0.15), and both were better than OPD (0.68). CONCLUSIONS: This network meta-analysis provided ranking for three different types of pancreaticoduodenectomy. The RPD and LPD can effectively improve the quality of surgery and are safe as well as feasible for OPD.

RESUMEN

BACKGROUND: Phlegmonous gastritis (PG) is a rare bacterial infection of the gastric submucosa and is related to septicemia, direct gastric mucosal injury, or the direct influence of infection or inflammation in neighboring organs. Here, we present a patient who had spontaneous biloma caused by choledocholithiasis and then PG resulting from bile leakage after biloma drainage. CASE SUMMARY: A 79-year-old man with a medical history of hypertension had persistent diffuse abdominal pain for 4 d. Physical examination showed stable vital signs, icteric sclera, diffuse abdominal tenderness, and muscle guarding. Laboratory tests showed hyperbilirubinemia and bandemia. Contrast computed tomography (CT) of the abdomen showed a dilated common bile duct and left subphrenic abscess. Left subphrenic abscess drainage revealed bilious fluid, and infected biloma was confirmed. Repeated abdominal CT for persistent epigastralgia after drainage showed gastric wall thickening. Esophagogastroduodenoscopy (EGD) showed an edematous, hyperemic gastric mucosa with poor distensibility. The gastric mucosal culture yielded Enterococcus faecalis. PG was diagnosed based on imaging, EGD findings, and gastric mucosal culture. The patient recovered successfully with antibiotic treatment. CONCLUSION: PG should be considered in patients with intraabdominal infection, especially from infected organs adjacent to the stomach.
