Common bile duct exploration in an elderly Asian population

Learning Curve of Laparoscopic Common Bile Duct Exploration: A Systematic Review

Background: Single-stage laparoscopic common bile duct exploration (LCBDE) with cholecystectomy has superior outcomes over two-stage endoscopic retrograde cholangiopancreatogram with interval cholecystectomy. With decreasing trend of LCBDE, this study aims to summarize the literature on learning curve (LC) in LCBDE. Materials and Methods: PubMed, Embase, Scopus, and the Cochrane Library were systematically searched for articles from inception to June 3, 2022 (PROSPERO Ref No: CRD42022328451). Basic clinical demographics were collected. Poisson means (95% confidence interval [95% CI]) was used to determine the number of cases required to surmount the LC (N_LC). Results: Eight articles (n = 2071 patients) reported LC outcomes in LCBDE with mean study period of 5.9 ± 2.8 years. Majority of studies (62.5%) used arbitrary methods of LC analysis. Most common outcomes reported were complications (any or major) (75%), open conversion (75%), length of stay (62.5%), and operating time (50%). Mean CBD diameter was 11.3 ± 4.8 mm (n = 1122 patients). Incidence of acute cholecystitis, acute cholangitis, and acute pancreatitis were 13.9% (n = 232/1668), 7.8% (n = 128/1629), and 13.7% (n = 229/1668), respectively. Pooled analysis of all the included studies showed N_LC of 78.8 cases (95% CI: 71.9-86.3). Studies that used cumulative sum control chart analysis, nonarbitrary methods, and arbitrary-based LC had N_LC of 152.0 (95% CI: 135.4-170.1), 108.0 (95% CI: 96.6-120.4), and 49.7 (95% CI: 42.0-58.3) cases, respectively. N_LC was 37.0 cases (95% CI: 29.1-46.5) for single surgeon LC, and 99.8 cases (95% CI: 90.2-110.0) for institutional LC. Conclusion: Studies reporting N_LC in LCBDE are heterogeneous. Further studies should use nonarbitrary methods of analysis for patient-reported outcome measures and procedure-specific morbidity.

3D Laparoscopic common bile duct exploration with primary repair by absorbable barbed suture is safe and feasible

Background and aim

Endoscopic retrograde cholangiopancreatography (ERCP), with interval laparoscopic cholecystectomy (LC), is the most common treatment approach for common bile duct (CBD) stones. However, recent studies show that single-stage laparoscopic CBD exploration (LCBDE) is safe and feasible. Three-dimensional (3D) laparoscopy enhances depth perception and facilitates intracorporeal suturing. The application of 3D technology for LCBDE is emerging, and we report our case series of 3D LCBDE.

Methods

We audited the 27 consecutive 3D LCBDE performed from July 2017 to January 2020. We have a liberal policy for magnetic resonance cholangiopancreatography (MRCP) in patients with deranged liver function tests (LFT). All CBD explorations were done through choledochotomy with a 5 mm flexible choledochoscope and primarily repaired with an absorbable barbed suture without a stent or T-tube.

Results

The mean age of patients was 68 (range 44-91) years, and 12 (44%) were male. The indications for surgery were choledocholithiasis 67% (n=18), cholangitis 22% (n=6), and gallstone pancreatitis 11% (n=3). About 67% (n=18) had pre-operative ERCP. About 37% (n=10) had pre-operative biliary stent. Pre-operative MRCP was done in 74% (n=20), and the mean diameter of CBD was 14.5 mm (range 7-30). The median operative time was 160 (range 80-265) min. The operative drain was inserted in 18 patients. One patient each (4%) had a bile leak and a retained stone. There was no open conversion, readmission, or mortality.

Conclusion

3D LCBDE with primary repair by an absorbable barbed suture is safe and feasible.

Relevance for patients

This paper emphasized that one stage LCBDE should be a treatment option which is comparable with two stage ERCP followed by LC to treat CBD stones. In addition, 3D technology and barbed sutures use in LCBDE are safe and useful.

Elderly patients (≥ 80 years) with acute calculous cholangitis have similar outcomes as non-elderly patients (< 80 years): Propensity score-matched analysis

BACKGROUND

Acute cholangitis (AC) is a disease spectrum with varying extent of severity. Age ≥ 75 years forms part of the criteria for moderate (Grade II) severity in both the Tokyo Guidelines (TG13 and TG18). Aging is associated with reduced physiological reserves, frailty, and sarcopenia. However, there is evidence that age itself is not the determinant of inferior outcomes in elective and emergency biliary diseases. There is a paucity of reports comparing clinical outcomes amongst elderly patients vs non-elderly patients with AC.

AIM

To investigate the effect of age (≥ 80 years) on AC's morbidity and mortality using propensity score matching (PSM).

METHODS

This is a single-center retrospective cohort study of all patients diagnosed with calculous AC (January 2016 to December 2016) and ≥ 80 years old (January 2012 to December 2016) at a tertiary university-affiliated teaching hospital. Inclusion criteria were patients who were treated for suspected or confirmed AC secondary to biliary stones. Patients with AC on a background of hepatobiliary malignancy, indwelling permanent metallic biliary stents, or concomitant pancreatitis were excluded. Elderly patients were defined as ≥ 80 years old in our study. A 1:1 PSM analysis was performed to reduce selection bias and address confounding factors. Study variables include comorbidities, vital parameters, laboratory and radiological investigations, and type of biliary decompression, including the time for endoscopic retrograde cholangiopancreatography (ERCP). Primary outcomes include in-hospital mortality, 30-d and 90-d mortality. Length of hospital stay (LOS) was the secondary outcome.

RESULTS

Four hundred fifty-seven patients with AC were included in this study (318 elderly, 139 non-elderly). PSM analysis resulted in a total of 224 patients (112 elderly, 112 non-elderly). The adoption of ERCP between elderly and non-elderly was similar in both the unmatched (elderly 64.8%, non-elderly 61.9%, P = 0.551) and matched cohorts (elderly 68.8% and non-elderly 58%, P = 0.096). The overall in-hospital mortality, 30-d mortality and 90-d mortality was 4.6%, 7.4% and 8.5% respectively, with no statistically significant differences between the elderly and non-elderly in both the unmatched and matched cohorts. LOS was longer in the unmatched cohort [elderly 8 d, interquartile range (IQR) 6-13, vs non-elderly 8 d, IQR 5-11, P = 0.040], but was comparable in the matched cohort (elderly 7.5 d, IQR 5-11, vs non-elderly 8 d, IQR 5-11, P = 0.982). Subgroup analysis of patients who underwent ERCP demonstrated the majority of the patients (n = 159/292, 54.5%) had delayed ERCP (> 72 h from presentation). There was no significant difference in LOS, 30-d mortality, 90-d mortality, and in-hospital mortality in patients who had delayed ERCP in both the unmatched and matched cohort (matched cohort: in-hospital mortality [n = 1/42 (2.4%) vs 1/26 (3.8%), P = 0.728], 30-d mortality [n = 2/42 (4.8%) vs 2/26 (7.7%), P = 0.618], 90-d mortality [n = 2/42 (4.8%) vs 2/26 (7.7%), P = 0.618], and LOS (median 8.5 d, IQR 6-11.3, vs 8.5 d, IQR 6-15.3, P = 0.929).

CONCLUSION

Mortality is indifferent in the elderly (≥ 80 years old) and non-elderly patients (< 80 years old) with AC.

Laparoscopic common bile duct exploration for elderly patients with choledocholithiasis: a systematic review and meta-analysis

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) has been becoming more and more popular in patients with symptomatic choledocholithiasis. However, the safety and effectiveness of LCBDE in elderly patients with choledocholithiasis is still uncertain. This meta-analysis is aimed to appraise the safety and feasibility of LCBDE for elderly patients with choledocholithiasis.

MATERIALS AND METHODS

Studies comparing elderly patients and younger patients who underwent LCBDE for common bile duct stone were reviewed and collected from the PubMed, Medline, EMBASE, and Cochrane Library. Primary outcomes were stone clearance rate, overall complication rate, and mortality rate. Secondary outcomes were operative time, conversion rate, pulmonary complication, bile leakage, reoperation, residual stone rate, and recurrent stone rate.

RESULTS

Nine studies, including two prospective studies and seven retrospective studies, met the inclusion criteria. There were 2004 patients in this meta-analysis, including 693 elderly patients and 1311 younger patients. There was no statistically significant difference between elderly patients and younger patients regarding stone clearance rate (OR 0.73; 95% CI 0.42-1.26; p = 0.25), overall complication rate (OR 1.31; 95% CI 0.94-1.82; p = 0.12), and mortality rate (OR 2.80; 95% CI 0.82-9.53; p = 0.10). Similarly, the operative time, conversion rate, bile leakage, reoperation, residual stone rate, and recurrent stone rate showed no significant difference between two groups (p > 0.05). While elderly patients showed high risk for pulmonary complication (OR 4.41; 95% CI 1.78-10.93; p = 0.001) compared with younger patients.

CONCLUSION

Although there is associated with higher pulmonary complication, LCBDE is still considered as a safe and effective treatment for elderly patients with choledocholithiasis.

Primary closure after laparoscopic common bile duct exploration is feasible for elderly patients: 5-Year experience at a single institution

OBJECTIVE

Laparoscopic common bile duct exploration (LCBDE) has been demonstrated safety and effective for patients with gallbladder stones and extrahepatic bile duct stones, however few studies reported its suitability for the treatment of elderly patients. Thus, our study aims to investigate the safety and feasibility of primary closure after LCBDE in the treatment of elderly patients.

METHODS

408 out of 499 patients with Gallbladder stones complicated with choledocholithiasis who were undergone LCBDE and primary closure were divided into two groups: Group A (<65 years old, n = 249) and Group B (≥65 years old, n = 159) and the related clinical data were compared and analyzed by statistical method.

RESULTS

Pre-operative American Society of Anesthesiologists (ASA) score of elderly patients was significantly higher than the younger patients (P < 0.05). In both groups, the positive rate of Choledocholithiasis and bile sludge at exploration, number of stones in CBD, utilization rate of Electro-hydraulic lithotripsy, estimated blood loss, successful duct clearance, the rate of postoperative bile leakage, postoperative bile duct stricture, reoperation, stone recurrence, and other postoperative complications showed no significant difference (p > 0.05). There were also no statistical differences between both groups in time to removal of drainage, postoperative hospital stay, readmission within 30 days and mortality (p > 0.05).

CONCLUSIONS

It is safe and feasible to treat the elderly patients with common bile duct stones under the premise of strict surgical indications, skilled laparoscopic procedures and accurate endoscopic suture techniques.

Percutaneous transcystic balloon dilation for common bile duct stone removal in high-surgical-risk patients with acute cholecystitis and co-existing choledocholithiasis

BACKGROUND

Percutaneous procedures to treat common bile duct (CBD) stones typically require access via intrahepatic bile ducts. This study aimed to describe the outcomes of a percutaneous transcystic approach that expelled the CBD stones into the duodenum after percutaneous transcystic balloon dilation of the ampulla (PTCBDA) for high-risk patients who present with acute cholecystitis and CBD stones.

METHODS

Patients diagnosed with acute cholecystitis and CBD stones who were deemed too high-risk for surgery or general anesthesia and were treated with PTCBDA and CBD stone removal between March 2010 and November 2015 were included for further analysis. Patients underwent emergency percutaneous transhepatic gallbladder drainage under ultrasound. Staged PTCBDA and CBD stone expulsion were performed. Outcomes evaluated included the success rate, causes of failure, and complications.

RESULTS

Eighteen patients met the inclusion criteria. CBD stones were successfully expelled in 16 patients. A second procedure was performed in one patient because of residual stones. The procedure failed in two patients because their stones were large. One patient developed bile peritonitis and underwent percutaneous catheter drainage.

DISCUSSION

Percutaneous transcystic anterograde expulsion of CBD stones may be a feasible and effective method for treating high-risk surgical patients with acute cholecystitis and co-existing CBD stones.

Tokyo Guidelines 2013 may be too restrictive and patients with moderate and severe acute cholecystitis can be managed by early cholecystectomy too

OBJECTIVE

The aim of this study was to determine whether early laparoscopic cholecystectomy (LC) is safe and feasible for patients diagnosed with moderate (grade 2) and severe (grade 3) acute cholecystitis (AC) according to the Tokyo Guidelines 2013 (TG13).

BACKGROUND

Early cholecystectomy is the current accepted standard of care for patients with mild (grade 1) and selected grade 2 AC based on TG13. For selected grade 2 and grade 3 AC, early percutaneous cholecystostomy (PC) followed by delayed cholecystectomy is recommended.

METHODS

Patients diagnosed with AC over a 14-month period were identified and divided into three grades of AC based upon chart review using the grading and severity indicators according to TG13.

RESULTS

A total of 149 patients underwent emergency LC. Eighty-two (55 %) patients were male. Eighty-four (56.4 %) patients were classified as grade 1 AC, 49 (32.9 %) as grade 2, and 16 (10.7 %) as grade 3. Eighty-three (98.8 %) patients with grade 1 AC underwent emergency LC, and 1 patient (1.2 %) underwent PC followed by emergency LC. The median length of hospital stay for grade 1 AC patients was 2 (1-11) days. There were 2 (2.4 %) readmissions with fever and no additional complications. Among the 65 patients identified with grade 2 or 3 AC, 6 (9.2 %) underwent PC followed by emergency LC. Fifty-nine (90.8 %) patients underwent emergency cholecystectomy: 58 (98.3 %) LC and one (1.7 %) open cholecystectomy. Among the 58 patients with LC, 3 (5.2 %) patients had open conversion and 10 (17.2 %) patients required subtotal cholecystectomy. One patient was converted to open due to bile duct injury and had hepaticojejunostomy repair. Two other patients were converted due to dense adhesions and inability to safely dissect Calot's triangle. The median length of hospital stay was 4 (1-28) days. There was one readmission for ileus.

CONCLUSION

Severity grading of AC is not the sole determinant of early LC. Patient comorbidity also impacts clinical decision. Confirmation in a larger cohort is warranted.

Low serum albumin may predict the need for gastric resection in patients with perforated peptic ulcer

PURPOSE

Perforated peptic ulcer (PPU) is a common surgical emergency and treatment involves omental patch repair (PR). Gastric resection (GR) is reserved for difficult pathologies. We audit the outcomes of GR at our institution and evaluate the pre-operative factors predicting the need for GR.

METHODS

This is a single-institution, retrospective study of patients with PPU who underwent surgery from 2004 to 2012. Demographics, clinical presentation and intra-operative findings were studied to identify factors predicting the need for GR in PPU. An audit of clinical outcomes and mortality for all patients with GR is reported.

RESULTS

537 (89.6 %) patients underwent PR and 62 (10.4 %) patients GR. Old age (p < 0.0001), female sex (p = 0.0123), non-steroidal anti-inflammatory drugs (NSAIDs) usage (p = 0.0008), previous history of peptic ulcer disease (PUD) (p = 0.0159), low hemoglobin (p < 0.0001), low serum albumin (p < 0.0001), high serum creatinine (p = 0.0030), high urea (p = 0.0006) and large ulcer size (p < 0.0001) predict the need for GR. On multivariate analysis only low serum albumin (OR 5.57, 95 % CI 1.56-19.84, p = 0.008) predicted the need for GR. The presence of Helicobacter pylori infection was protective against GR (OR 0.25, 95 %CI 0.14-0.44, p < 0.0001). Morbidity and mortality of GR was 27.7 and 24.2 %, respectively.

CONCLUSION

GR is needed in one in ten cases of PPU. Low serum albumin predicted the need for GR on multivariate analysis. Morbidity and mortality of GR remains high.

Laparoscopic Transcystic Common Bile Duct Exploration in the Elderly is as Effective and Safe as in Younger Patients

BACKGROUND

Choledocholithiasis represents a greater proportion of gallstone in the elderly. Elderly patients have more comorbidity, which could increase the operative risk and postoperative complications. However, no study has focused on the effect and safety of laparoscopic transcystic common bile duct exploration (LTCBDE) in elderly patients. The aim of this study was to investigate whether LTCBDE can be performed effectively and safely in elderly patients.

METHODS

This is a retrospective study of patients who underwent LTCBDE for choledocholithiasis performed from January 2010 to December 2012. Patients of age 70 or older were included in the elderly group. The rest integrated the younger group. Demographic data and perioperative parameters were compared between groups.

RESULTS

From January 2010 to December 2012, 171 patients admitted for choledocholithiasis and gallstone attempted a single-step treatment combining LTCBDE and laparoscopic cholecystectomy. There were 104 women (60.8%) and 67 men (39.2%) with a median age of 57 (range 24-87) years. Elderly patients had significantly more preoperative risk factors. However, there was no significant difference in the success rate of LTCBDE (96.9% versus 92.7%, P = .142) for the two groups. The operative time was a little longer in elderly group than in younger group: median 80 (60-110) minutes versus 70 (50-95) minutes, respectively (P < .001). Postoperative recovery was slower in elderly group than in younger group, as reflected by a longer median postoperative hospital stay (2 days versus 1 day, P < .001) and a higher rate of abdominal drain placed (17.1% versus 8.5%, P = .202). The rates of postoperative complications at discharge were similar between groups (3.0% versus 4.9%, P = .952).

CONCLUSION

LTCBDE in the elderly patients is as effective and safe as in younger patients.

Role of laparoscopic common bile duct exploration in the management of choledocholithiasis

Surgical fraternity has not yet arrived at any consensus for adequate treatment of choledocholithiasis. Sequential treatment in the form of pre-operative endoscopic retrograde cholangio-pancreatography followed by laparoscopic cholecystectomy (LC) is considered as optimal treatment till date. With refinements in technique and expertise in field of minimal access surgery, many centres in the world have started offering one stage management of choledocholithiasis by LC with laparoscopic common bile duct exploration (LCBDE). Various modalities have been tried for entering into concurrent common bile duct (CBD) [transcystic (TC) vs transcholedochal (TD)], for confirming stone clearance (intraoperative cholangiogram vs choledochoscopy), and for closure of choledochotomy (T-tube vs biliary stent vs primary closure) during LCBDE. Both TC and TD approaches are safe and effective. TD stone extraction is involved with an increased risk of bile leaks and requires more expertise in intra-corporeal suturing and choledochoscopy. Choice depends on number of stones, size of stone, diameter of cystic duct and CBD. This review article was undertaken to evaluate the role of LCBDE for the management of choledocholithiasis.

Effects of intravenously infused lidocaine on analgesia and gastrointestinal function of patients receiving laparoscopic common bile duct exploration

Objective:

To evaluate the effects of intravenously infused lidocaine on analgesia and gastrointestinal function of patients receiving laparoscopic common bile duct exploration.

Methods:

Seventy-eight patients with cholelithiasis were randomly divided into a treatment group and a control group (n=39) that all had laparoscopic common bile duct exploration. The treatment group was intravenously infused with 1.5 mg/kg lidocaine by using a venous pump under anesthesia induction at the speed of 2 mg·kg^-1 ·h^-1 until the end of surgery, while the control group was given normal saline with the same volume.

Results:

All patients successfully completed the surgery, with similar surgical time, incision length and intraoperative blood loss. The required lidocaine concentrations of the treatment group were 2.64±1.23 μg/ml, 1.14±0.4 μg/ml and 0.93±0.32 μg/ml respectively 2 hour, 12 hour and 48 hour after surgery. Pain score of the treatment group, which was significantly lower than that of the control group at the postoperative 2 hour (P<0.05), was similar to those of the control group at the postoperative 12 hour and 48 hour. With extended time, the pain score significantly decreased (P<0.05). The treatment group had significantly shorter first anal exhaust time and first defecation time than those of the control group (P<0.05). Adverse reactions, such as nausea and vomiting, dizziness, headache, subcutaneous emphysema and fat liquefaction of incision, occurred similarly in the two groups, which were alleviated by symptomatic treatment.

Conclusion:

Laparoscopic common bile duct exploration is a promising minimally invasive surgery for patients with cholelithiasis, during which intravenously infused lidocaine can rapidly recover the gastrointestinal function and exert short-term analgesic effects, with mild adverse reactions also.
