Biliary leakage following pancreaticoduodenectomy: Prevalence, risk factors and management.

BACKGROUND: Few studies investigated biliary leakage after pancreaticoduodenectomy (PD) especially when compared to postoperative pancreatic fistula (POPF). This study was to determine the incidence of biliary leakage after PD, predisposing factors of biliary leakage, and its management. METHODS: We retrospectively studied all patients who underwent PD from January 2008 to December 2017 at Gastrointestinal Surgery Center, Mansoura University, Egypt. According to occurrence of postoperative biliary leakage, patients were divided into two groups. Group (1) included patients who developed biliary leakage and group (2) included patients without identified biliary leakage. The preoperative data, operative details, and postoperative morbidity and mortality were analyzed. RESULTS: The study included 555 patients. Forty-four patients (7.9%) developed biliary leakage. Ten patients (1.8%) had concomitant POPF. Multivariate analysis identified obesity and time needed for hepaticojejunostomy reconstruction as independent risk factors of biliary leakage, and no history of preoperative endoscopic retrograde cholangiopancreatiography (ERCP) as protective factor. Biliary leakage from hepaticojejunostomy after PD leads to a significant increase in development of delayed gastric emptying, and wound infection. The median hospital stay and time to resume oral intake were significantly greater in the biliary leakage group. Non-surgical management was needed in 40 patients (90.9%). Only 4 patients (9.1%) required re-exploration due to biliary peritonitis and associated POPF. The mortality rate in the biliary leakage group was significantly higher than that of the non-biliary leakage group (6.8% vs 3.9%, P = 0.05). CONCLUSIONS: Obesity and time needed for hepaticojejunostomy reconstruction are independent risk factors of biliary leakage, and no history of preoperative ERCP is protective factor. Biliary leakage increases the risk of morbidity and mortality especially if concomitant with POPF. However, biliary leakage can be conservatively managed in majority of cases.

Trends and outcomes of pancreaticoduodenectomy for periampullary tumors: A 25-year single-center study of 1000 consecutive cases.

AIM: To evaluate the evolution, trends in surgical approaches and reconstruction techniques, and important lessons learned from performing 1000 consecutive pancreaticoduodenectomies (PDs) for periampullary tumors. METHODS: This is a retrospective review of the data of all patients who underwent PD for periampullary tumor during the period from January 1993 to April 2017. The data were categorized into three periods, including early period (1993-2002), middle period (2003-2012), and late period (2013-2017). RESULTS: The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the periods. CONCLUSION: Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%.

Outcomes of pancreaticoduodenectomy in elderly patients.

BACKGROUND: Although the mortality and morbidity of pancreaticoduodenectomy (PD) have improved significantly over the past years, the concerns for elderly patients undergoing PD are still present. Furthermore, the frequency of PD is increasing because of the increasing proportion of elderly patients and the increasing incidence of periampullary tumors. This study aimed to analyze the outcomes of PD in elderly patients. METHODS: We studied all patients who had undergone PD in our center between January 1995 and February 2015. The patients were divided into three groups based on age: group I (patients aged <60 years), group II (those aged 60 to 69 years) and group III (those aged ≥70 years). The primary outcome was the rate of total postoperative complications. Secondary endpoint included total operative time, hospital mortality, length of postoperative hospital stay, delayed gastric emptying, re-exploration, and survival rate. RESULTS: A total of 828 patients who had undergone PD for resection of periampullary tumor were included in this study. There were 579 (69.9%) patients in group I, 201 (24.3%) in group II, and 48 (5.8%) in group III. The overall incidence of complications was higher in elderly patients (25.9% in group I, 36.8% in group II, and 37.5% in group III; P=0.006). There were more patients complicated with delayed gastric emptying in group II compared with the other two groups. There was no significant difference in the incidence of postoperative pancreatic fistula, biliary leakage, pancreatitis, pulmonary complications and hospital mortality. CONCLUSIONS: PD can be performed safely in selected elderly patients. Advanced age alone should not be a contraindication for PD. The outcome of elderly patients who have undergone PD is similar to that of younger patients, and the increased rate of complications is due to the presence of associated comorbidities.

Early Versus Late Cholecystectomy After Clearance of Common Bile Duct Stones by Endoscopic Retrograde Cholangiopancreatography: A Prospective Randomized Study.

INTRODUCTION: The time interval between endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) is a matter of debate. This study was planned to compare early LC versus late LC. PATIENTS AND METHODS: This is a prospective randomized study on patients who are presented with concomitant gallbladder and common bile duct stone. The study population was divided into two groups; group (A) managed by early LC within three days after ERCP; and group (B) managed by late LC one month after ERCP. RESULTS: No significant difference between both groups as regards the conversion rate, the degree of adhesion, cystic duct diameter, and intraoperative common bile duct injury or bleeding. Recurrent biliary symptoms were significantly more in delayed LC group in 7 (12.71%) patient versus 1 patient in early LC (P=0.03). CONCLUSIONS: No significant difference between both groups as regards the conversion rate. Recurrent biliary symptoms were significantly more in delayed LC while waiting LC. Morbidity was significantly more in delayed LC.

Management and Outcome of Borderline Common Bile Duct with Stones: A Prospective Randomized Study.

INTRODUCTION: Management of common bile duct stones (CBDS) in patients with borderline CBD presents a surgical challenge. The aim of this study was to compare conservative treatment with endoscopic stone extraction for the treatment of borderline CBD with stones. PATIENTS AND METHODS: This prospective randomized controlled trial includes patients with CBDS in borderline CBD (CBD <10 mm) associated with gallbladder stones who were treated with conservative treatment or endoscopic stone extraction followed by laparoscopic cholecystectomy (LC) and intraoperative cholangiogram (IOC). The primary outcome was successful CBD clearance. The secondary outcomes were the overall complications, cost, and hospital stay. RESULTS: LC and IOC revealed complete clearance of CBDS in 48 (96%) cases in the endoscopic retrograde cholangiopancreatography (ERCP) group (52% of patients by ERCP, and 44% of patient passed the stone spontaneously), and in the remaining two patients, the CBDS was removed by transcystic exploration. In the conservative group, LC and IOC revealed complete clearance of CBDS in 90% of cases, and in the remaining 10% of patients, the CBDS was removed by transcystic exploration. Post-ERCP pancreatitis (PEP) is noticed significantly in the ERCP group (2 [4%] versus 8 [16%]; P = .04). The average net cost was significantly higher in the ERCP group. Recurrent biliary symptoms developed significantly in the ERCP group after 1 year (10% versus 0%; P = .02) in the form of recurrent cholangititis and recurrent CBDS. CONCLUSIONS: Management of CBDS in patients with borderline CBD represents a surgical challenge. Borderline CBD increases the technical difficulty of ERCP and increases the risk of PEP. Conservative management of CBDS in borderline CBD not only avoids the risks inherent in ERCP and unnecessary preoperative ERCP, but it is also effective in clearing CBDS. The hepatobiliary surgeon should consider a conservative line of treatment in CBDS in borderline CBD in order to decrease the cost and avoid unnecessary ERCP.

Long-term follow-up of 120 patients after hepaticojejunostomy for treatment of post-cholecystectomy bile duct injuries: A retrospective cohort study.

BACKGROUND: Long-term follow-up is essential for assessment of success of the surgical repair of post-cholecystectomy bile duct injuries (BDI). Factors affecting the long-term outcome and satisfactory length of follow-up have been little reported in the literature. The aim of this study is long-term evaluation of hepaticojejunostomy regarding clinical, radiological, laboratory and quality of life assessment. METHOD: Between January 1992 to December 2007, 120 patients with postcholecystectomy bile duct injury surgically treated by hepaticojejunostomy Roux-en-Y were followed up for 20 years in Mansoura Gastro-enterology Center. Long-term outcomes and quality of life (QOL) were evaluated for all patients. Univariate and multivariate analyses were done for detection of factors affecting long-term outcome. RESULTS: The median follow up period was 149 months, range (70-246 months). Successful long-term outcome was detected in 106 (88.3%) patients. Long-term complications were detected in 35 (29%) patients. Fourteen (11.6%) patients developed anastomotic stricture within different follow up intervals up to 17 years, of which. Seventeen (14.2%) patients developed recurrent episodes of cholangitis at median interval 48 months, range (2-156 months). Post-ERCP pancreatitis, number of anastomosis, operative time, post-operative early complications, and post-operative bile leak were predictors for poor outcome. Physical component was much more affected than mental component in QOL. CONCLUSION: Management of BDI in specialized centers is highly recommended. Longer time for follow-up of the patients of surgical repair of bile duct injury up to 20 years should be adopted to ensure successful outcome. Quality of life assessment is essential component of long-term follow-up.

Quality-of-life measures after single-access versus conventional laparoscopic cholecystectomy: a prospective randomized study.

BACKGROUND: This study aimed to compare the short-term outcomes of single-access laparoscopic cholecystectomy (SALC) and conventional laparoscopic cholecystectomy (CLC). METHODS: In a prospective study, patients with symptomatic cholelithiasis were randomized to SALC or CLC with follow-up at 1 week, 1 and 6 months. The primary end point of this study was to assess the total outcomes of quality of life using the EuroQoL EQ-5D questionnaire. The secondary end points were postoperative pain, analgesia requirement and duration of use, operative time, perioperative complications, estimated blood loss, hospital stay, cosmesis outcome, and number of days required to return to normal activities. RESULTS: A total of 269 patients were prospectively randomized into two groups (125 in each group after excluding 19 patients for various reasons). The SALC procedure was done safely without intraoperative or major postoperative complications. In four SALC patients, an extra epigastric port was inserted to enhance exposure. There was no open conversion in either group. SALC patients reported better results among four of the EuroQoL EQ-5D dimensions (mobility, self-care, activity, and pain/discomfort) at 1 week after surgery, an improved pain profile at 4, 12, and 24 h, better cosmetic outcome at 1 and 6 months (P ≤ 0.01), shorter duration of need for analgesia (P ≤ 0.02), and earlier return to normal activities (P ≤ 0.026). Operative times, hospital stay, QOL at 1 and 6 months postoperatively, and estimated blood loss were similar for both procedures. CONCLUSION: This study supports other studies that show that SALC is a feasible and promising alternative to traditional laparoscopic cholecystectomy in selected patients with better cosmesis, QOL, and improved postoperative pain results, and it can be performed with the existing laparoscopic instruments.

Clipless laparoscopic cholecystectomy using the Harmonic scalpel for cirrhotic patients: a prospective randomized study.

BACKGROUND: Improved laparoscopic experiences have made laparoscopic cholecystectomy (LC) feasible options for cirrhotic patients. This study aimed to compare the traditional method for LC with LC using the Harmonic scalpel in terms of safety and efficacy for cirrhotic patients. METHODS: In this study, group A (60 patients) underwent LC by the traditional method (TM) with clipping of both the cystic duct and artery and dissection of the gallbladder by diathermy, and group B (60 patients) had LC performed using Harmonic scalpel (HS) closure and division of both the cystic duct and artery with dissection of the gallbladder by the HS. The perioperative data were recorded. RESULTS: The operation with the Harmonic scalpel was performed in less time than TM (45.17 ± 10.54 vs. 69.71 ± 13.01 min; p = 0.0001). The intraoperative blood loss was significantly more with TM (133 ± 131.13 l vs. 70.13 ± 80.79 ml; p = 0.002). The conversion rate was 5% with TM and 3.3% with HS (p = 0.65). The incidence of gallbladder peroration was lower in the HS group (10% vs. 18.3%; p = 0.03). Bile leak was encountered in 1.7% with HS and 3.3% with TM (p = 0.45). The visual analog scale (VAS) for pain with HS on postoperative day 1 was (3.07 ± 2.02 vs. 4.4 ± 2.11 (p = 0.001). CONCLUSION: For cirrhotic patients, LC still is more complicated and difficult than for patients without cirrhosis. The Harmonic scalpel provides complete hemobiliary stasis and is a safe alternative to the standard clipping of the cystic duct and artery for cirrhotic patients. It offers a shorter operative duration and less blood loss.
