FREQUENCY OF EASY AND DIFFICULT LAPAROSCOPIC CHOLECYSTECTOMY FOR CHOLELITHIASIS

The prevalence of gallstone disease is influenced by factors such as age, gender, and marital status. Ultrasonography is important for screening. Laparoscopic cholecystectomy (LC) is the standard treatment for symptomatic cholelithiasis, but some cases may require conversion to open surgery (OC). Preoperative ultrasound assessments, particularly the common bile duct (CBD) diameter, may help predict the difficulty of LC and prepare for potential complications. Objective: The objectives of this study are to assess the frequency of easy and difficult laparoscopic cholecystectomy in patients with cholelithiasis and to compare the mean diameter of the common bile duct between cases of easy and difficult laparoscopic cholecystectomy. Methods: This sctional study was conducted from February 10, 2023, to August 10, 2023, and included 170 patients (ages 18-60 years) undergoing laparoscopic cholecystectomy for cholelithiasis. Both genders were included. Variables such as age, gender, diabetes, hypertension, and cholecystectomy status were recorded. The mean and standard deviation (SD) were calculated for age and CBD diameter. An independent t-test was used to compare CBD diameters between easy and difficult LC cases. Chi-square tests were applied to control for effect modifiers. Results: The mean age of the patients was 52.32 ± 4.89 years. Other patient characteristics included an average height of 162.90 ± 9.25 cm, weight of 75.95 ± 12.32 kg, and BMI of 27.47 ± 4.72. The common bile duct diameter was 4.55 ± 1.42 mm. Gender distribution showed 54.7% male and 45.3% female patients. Of the 170 patients, 84 (49.4%) were classified as easy LC cases, while 86 (50.6%) were classified as difficult. The mean CBD diameter was significantly different between the two groups, measuring 3.54 ± 1.03 mm in easy cases and 5.52 ± 1.02 mm in difficult cases (p = 0.001). Conclusion: This study highlights the importance of preoperative assessment of common bile duct diameter in predicting the difficulty of laparoscopic cholecystectomy. Patients with a larger CBD diameter are more likely to experience a difficult LC, emphasizing the need for personalized surgical planning. These findings underscore the value of preoperative ultrasonography in optimizing patient outcomes and reducing the risk of conversion to open surgery.

Pre-Operative Evaluation of Risk Factors for Difficult Laparoscopic Cholecystectomy

Cholelithiasis or the gallstone disease is the most common biliary pathology. 10-15% population of western world is estimated to be affected by gallstone disease, of which majority remains asymptomatic (>80%) and 1-2 % of these asymptomatic patients will develop symptoms needing surgery per year. In this prospective study, 77 patients years undergoing elective Laparoscopic Cholecystectomy (LC) and meeting all inclusion criteria in Department of General Surgery, Nepal Medical College and Teaching Hospital over period of 1 year. History, detailed clinical examination and laboratory investigations were performed as per the working proforma. Operative time and conversion to open cholecystectomy were recorded. The association between clinical, laboratory and sonographic factors with difficult laparoscopy were obtained. Data analysis was done using SPSS-17 version. Out of 77 patients, 63 were females. Body mass index (BMI) above 30 representing obese population were 33.2% with p value 0.0004. Also, 41.5% patients had history of acute cholecystitis while 12.9% patients had previous history of abdominal surgery and 70.1% patients had history of recurrent abdominal pain. Total of 19.4% patients had increased leucocyte count. On ultrasonography thickened GB wall of >3 mm was seen in 42.8%, distended GB was seen in 41.5%, stone size of >1 cm was seen in 70.1% patients and multiple stones were seen in 84.4%. Similarly, duration of surgery was >90 mins in 31.1% and 7.04% patients underwent conversion to open cholecystectomy both of which were considered difficult laparoscopy. Our study reveled that clinical factors like age, BMI, history of acute cholecystitis, previous history of recurrent abdominal pain and past history of abdominal surgery had significant association in prediction of difficult LC.

C-Reactive Protein as A Useful Predictor of Difficult Laparoscopic Cholecystectomy

Objective: To determine the ability of C-reactive protein as a useful predictor of difficult laparoscopic cholecystectomy. Study Design: Cross sectional study. Place and Duration of Study: General Surgery unit of Combined Military Hospital, Rawalpindi Pakistan, from Nov 2021–Nov 2022. Methodology: Fifty-six patients who underwent emergency or early laparoscopic cholecystectomy were made part of this study. After an informed consent age, gender, Body Mass Index and C-Reactive Protein levels were documented. Patients then underwent surgery and operative time along with “Nassar Difficulty Grade” was documented to define difficult cholecystectomy. Results: A total of 56 patients who were scheduled to undergo laparoscopic cholecystectomy were included with mean age of 44.32±5.37 years. 23(41.10%) were male patients while 33(58.90%) were female patients. Mean CRP levels were 20.00±8.81 mg/L. Frequency of "difficult laparoscopic cholecystectomy" in patients who had high preoperative CRP was 15/22(68.18%) while in patients who had low preoperative CRP it was 13/34(38.23%). Additionally, bivariate analysis of CRP levels and mean operative time showed that Pearson correlation coefficient (r) value was 0.355 showing a significant positive correlation (p=0.007). Conclusion: C-reactive protein levels in patients undergoing laparoscopic cholecystectomy for gallstones or any of its related problems are helpful in predicting whether or not the patient will have a challenging laparoscopic cholecystectomy.

The Hanging Strap Method: A Safe and Easy-to-Use Surgical Technique for Surgeons-in-Training Performing Difficult Laparoscopic Cholecystectomy.

Introduction Surgeons-in-training (SIT) perform laparoscopic cholecystectomy (LC); however, it is challenging to complete the procedure safely in difficult cases. We present a surgical technique during difficult LC, which we named the hanging strap method. Methods We retrospectively compared the perioperative outcomes between patients undergoing difficult LC with the hanging strap method (HANGS, n = 34), and patients undergoing difficult LC without the hanging strap method (non-HANGS, n = 56) from 2022 and 2024. Difficult LC was defined as cases classified as more than grade II cholecystitis by the Tokyo Guidelines 18 and cases when LC was undergoing over five days after the onset of cholecystitis. Results The proportion of SIT with post-graduate year (PGY) ≤ 7 was significantly higher in the HANGS group than in the non-HANGS group (82.4% vs. 33.9%, P < 0.001). The overall rate of bile duct injury (BDI), postoperative bile leakage and operative mortality were zero in the whole cohort. There were no significant differences between the HANGS and non-HANGS groups in background characteristics, operative time (122 min vs. 132 min, P = 0.830) and surgical blood loss (14 mL vs. 24 mL, P = 0.533). Conclusions Our findings suggested that the hanging strap method is safe and easy to use for difficult LC. We recommend that the current method be selected as one of the surgical techniques for SIT when performing difficult LC.

Prospective validation of a preoperative scoring system for difficult laparoscopy cholecystectomy.

Difficult laparoscopic cholecystectomy (LC) is defined by its surgical outcomes, including operative time, conversion to open surgery, bile duct and/or vascular injury. Difficult LC can be graded based on intraoperative findings. The main objective of this study is to apply and validate the reliability of their proposed risk score to predict the operative difficulty of an LC, based on their own validated intraoperative scale. Single-center prospective cohort study from 01/2020-12-2023. 367 patients > 18years who underwent LC were included. The preoperative risk scale and intraoperative grading system were registered. Surgical outcomes were determined. Predictive accuracy was evaluated by the Receiver Operator Characteristic curve, sensitivity, specificity, positive, and negative predictive values, and Youden's Index (J). Patients' mean age was 44.1 ± 15.3years. According to the risk score, 39.5% LC were "low" risk difficulty, 49.3% were "medium" risk, and 11.2% were "high" risk difficult LC. Based on the intraoperative grading system, 31.9% were difficult LC (Nassar grades 3-4) and 68.1% were easy LC (Nassar grades 1-2). There was a statistically significant correlation (0.428, p < 0.05) between the preoperative risk score and the intraoperative grading system. The AUC for the preoperative risk score scale and intraoperative difficult LC was 0.735 (95% CI 0.687-0.779) (J: 0.34). A preoperative risk score > 1.5 had an 83.7% sensitivity and a 50.8% specificity for intraoperative difficult LC. A predictive preoperative score for difficult LC and a routine collection of the intraoperative difficulty should be implemented to improve surgical outcomes and surgical planning.

Predictors of the Difficulty of Laparoscopic Cholecystectomy After Percutaneous Transhepatic Gallbladder Drainage for Grade II Acute Cholecystitis.

The predictors of difficulty performing laparoscopic cholecystectomy (LC) following percutaneous transhepatic gallbladder drainage (PTGBD) for grade II acute cholecystitis have not been clearly understood. This retrospective study was performed between January 2019 and February 2023 and involved 102 eligible patients with grade II acute cholecystitis. Patients were categorized into 2 groups: difficult LC group (n=14) and nondifficult LC group (n=88). Preoperative characteristics and postoperative outcomes were analyzed, and a logistic regression model was used for multivariate analyses of the significant factors identified in the univariate analyses. Logistic multivariable regression analysis revealed that C-reactive protein (CRP) levels (odds ratio [OR]: 1.028, 95% confidence interval [CI]: 1.013-1.044; P <0.05), and time intervals between PTGBD and LC (OR: 1.047, 95% CI: 1.003-1.092; P =0.034) were independent predictors of difficult LC. When preoperative CRP was >154mg/L, LC difficulty, blood loss, and operative time increased ( P <0.05, P =0.01, P =0.01, respectively) compared with CRP <154mg/L. Difficult LC, increased blood loss, and longer operative time occurred more frequently when the interval between PTGBD and LC was >35 days compared with <35 days ( P <0.05, P =0.003, P =0.002, respectively). CRP levels >154mg/L and intervals between PTGBD and LC exceeding 35 days are associated with greater LC difficulty.

Subtotal laparoscopic cholecystectomy versus conversion to open as a bailout procedure: a cohort study

BackgroundThe aim of this study is to evaluate morbidity and mortality in patients taken to conversion to open procedure (CO) and subtotal laparoscopic cholecystectomy (SLC) as bailout procedures when performing difficult laparoscopic cholecystectomy.MethodThis observational cohort study retrospectively analyzed patients taken to SLC or CO as bailout surgery during difficult laparoscopic cholecystectomy between 2014 and 2022. Univariable and multivariable logistic regression models were used to identify prognostic factors for morbimortality.ResultsA total of 675 patients were included. Of the 675 patients (mean [SD] age 63.85 ± 16.00 years; 390 [57.7%] male) included in the analysis, 452 (67%) underwent CO and 223 (33%) underwent SLC. Overall, neither procedure had an increased risk of major complications (89 [19.69%] vs 35 [15.69%] P.207). However, CO had an increased risk of bile duct injury (18 [3.98] vs 1 [0.44] P.009), bleeding (mean [SD] 165.43 ± 368.57 vs 43.25 ± 123.42 P < .001), intestinal injury (20 [4.42%] vs 0 [0.00] P.001), and wound infection (18 [3.98%] vs 2 [0.89%] P.026), while SLC had a higher risk of bile leak (15 [3.31] vs 16 [7.17] P.024). On the multivariable analysis, Charlson comorbidity index (odds ratio [OR], 1.20; CI95%, 1.01–1.42), use of anticoagulant agents (OR, 2.56; CI95%, 1.21–5.44), classification of severity of cholecystitis grade III (OR, 2.96; CI95%, 1.48–5.94), and emergency admission (OR, 6.07; CI95%, 1.33–27.74) were associated with presenting major complications.ConclusionsSLC was less associated with complications; however, there is scant evidence on its long-term outcomes. Further research is needed on SLC to establish if it is the safest in the long-term as a bailout procedure.

Liver pucker sign: predictor of difficult laparoscopic cholecystectomy: a case series.

Pucker sign is the depression of the liver in the region of the gallbladder due to a high degree of chronic contractive inflammation of the gallbladder. It usually develops in patients who have a delayed cholecystectomy after acute cholecystitis due to a high degree of chronic contractive inflammation of the gallbladder and contraction of the cystic plate. It is an essential finding either preoperatively or intraoperatively as it can act as a stopping rule during cholecystectomy (act as a guide that cholecystectomy will be difficult). The authors here report three cases of pucker sign that were incidentally discovered during laparoscopy. Chronic cholecystitis is a prolonged, subacute condition caused by inflammation of the gallbladder, which mostly occurs in the setting of cholelithiasis. Laparoscopic cholecystectomy is the procedure of choice for symptomatic cholelithiasis. Hence, it would be beneficial to be aware of reliable signs that predict difficult Laparoscopic cholecystectomy. Pucker sign usually predicts increased operative difficulty as there is an operative danger of biliary or vascular injury. The pucker sign is a novel indicator of significant persistent inflammation and heightened difficulty during surgery. It might establish a halting rule that modifies the procedure's management and raises its level of safety.

New Proposed Classification of Difficulty in Laparoscopic Cholecystectomy.

Background: Difficult laparoscopic cholecystectomy (LC) has been challenging for surgeons. Randhawa's system used operative time, complications, and conversion to define three difficulty grades. However, using fixed numbers of operative time as dividers among three groups might not be applicable universally. This study aimed to propose new classification with more flexible parameters. Methods: This retrospective cohort study was conducted with patients who underwent LC because of gallstone-related diseases between January 2017 and December 2021 at Thammasat University Hospital. The exclusion criteria were (1) emergent LC for acute cholecystitis, (2) other procedures performed in the same setting of LC, (3) incomplete information, and (4) LC converted to open cholecystectomy. Patients were categorized into three groups using Randhawa's classification. Thereafter, new classification using mean and standard deviation was applied to reclassify patients into three new groups. The comparison between two grading results was performed to prove the advantage of new classification. Results: Total of 523 patients who underwent LC were included with median age 59.3 years old and 60.8% female. By Randhawa classification, proportions of easy, difficult, and very difficult groups were 39%, 53.7%, and 7.3%, respectively. Then, the new operative-time dividers among three groups were changed from 60 and 120 minutes to mean and mean + 2SD, respectively. Reclassified three difficult groups were 38.9%, 57.1%, and 4%. The comparison demonstrated new classification as more flexible and more compatible with each individual surgeon. Conclusions: New surgeon-referenced grading system of difficult LC included surgeon's factors, not only unfavorable operative findings. This classification should be more flexible than the previous criterion-referenced one. Thai Clinical Trials Registry at https://www.thaiclinicaltrials.org with Number TCTR20220426003.

Beyond the Expected: Evaluating Preoperative Predictors of a Difficult Cholecystectomy Aboard the USNS Comfort.

Mini abstract Typical preoperative markers of a difficult laparoscopic cholecystectomy did not apply during the US Naval ShipComfort Deployment in 2019. This prospective study reveals the importance of preparedness for short-term surgical missions, the impact of health care disparities on the severity of disease, and the need for deliberate and thoughtful engagement with host-nation partners.

3D visualization systems improve operator efficiency during difficult laparoscopic cholecystectomy: a retrospective blinded review of surgical videos.

3D visualization systems in laparoscopic surgery have been proposed to improve manual task handling compared to 2D, however, few studies have compared the intra-operative efficacy in laparoscopic cholecystectomy (LC). The aim of this study is to determine if there is a benefit in intra-operative efficiency when using a 3D visualization system in difficult LC compared to traditional 2D visualization systems. Retrospective analysis of 'difficult' LCs (Grades 3 or 4) was completed. The assessor was blinded as all cases were recorded and viewed in 2D only. Variables collected included time to complete steps, missed hook diathermy attempts, failed grasp attempts, missed clip attempts and preparation steps for intra-operative cholangiogram (IOC). Multiple linear regression was undertaken for time variables, Poisson regression or negative binomial regression was completed for continuous variables. Fifty-two operative videos of 'difficult' LC were reviewed. 3D systems were associated with reduced operative times, although this was not statistically significant (CI: -2.93-14.93, P-value = 0.183). Dissection of the anterior fold to achieve the critical view of safety was significantly faster by 3.55 min (CI: 1.215-9.206, P-value = 0.002), and with considerably fewer errors when using 3D systems. Fewer IOC preparation errors were observed with a 3D system compared with a 2D system. 3D systems appear to enhance operator efficiency, allowing faster completion of critical steps with fewer errors. This pilot study underscores the utility of video annotation for intra-operative assessment and suggests that, in larger multi-centre studies, 3D systems may demonstrate superior intra-operative efficiency over 2D systems during a 'difficult' LC.

Predicting Difficulty in Laparoscopic Cholecystectomies: An Evaluation of the Labbad-Vivas Score and Its Correlation With the Parkland Grading Scale.

Background Difficult laparoscopic cholecystectomy (DLC) denotes the surgical extraction of the gallbladder under circumstances where associated conditions within the same organ, adjacent structures, or patient-specific conditions impede a smooth, expeditious, and comfortable dissection. It is imperative to utilize tools that aid in anticipating this challenging surgical scenario, enabling the implementation of appropriate measures. Objective This study aimed to assess the effectiveness of the Labbad-Vivas score (LVS) in predicting DLC and its correlation with the Parkland Grading Scale (PGS). Methodology A prospective study was conducted, including patients diagnosed with gallstone disease undergoing LC (laparoscopic cholecystectomy) at the "Dr. Luis Razetti" University Hospital in Barcelona, Venezuela, between September and December 2023. Results Forty patients were studied, with 80% (n=32) being female and 95% (n=38) under the age of 65; surgeries were elective in 72.5% (n=29) of cases; 35% (n=14) had an LVS ≥16 (difficult cholecystectomy); and 62.5% (n=25) of patients presented Grades 1 and 2 on the PGS. Total cholecystectomy was performed in 95% (n=38) of the patients. The LVS showed a sensitivity of 80%, specificity of 92%, positive predictive value of 85.7%, and negative predictive value of 88.5% to predict DLC, with an area under the receiver operating characteristic curve of 0.897 (95% confidence interval (CI) = 0.792-1.003). A Pearson correlation coefficient of 0.805 (95% CI = 0.656 - 0.904) was obtained between both scores. Conclusion The use of the LVS score in the preoperative setting is feasible as a predictor of DLC, given its effectiveness and high correlation with the PGS.

A prospective comparative study of the intraoperative difficulties during laparoscopic cholecystectomy in patients taking homeopathic medications for cholelithiasis versus cholelithiasis patients with no history of homeopathic medication

Background: Gallstone disease is one of the most prevalent gastrointestinal diseases with a substantial burden to health-care systems. Patients present with right upper quadrant pain, dyspepsia, nausea or vomiting. Owing to the side effects of allopathic drugs, many patients resort to homeopathic treatment for relief of pain. There are several homeopathic drugs that decrease the pain of cholecystitis as well as high cholesterol in these patients but cannot cure them off the disease. Finally, they come to general surgeon for cholecystectomy. We have noticed that performing laparoscopic cholecystectomy (LC) in these patients is difficult and time consuming. Aims and Objectives: To determine whether or not homeopathic medicine intake for treatment of cholelithiasis act as an independent factor that leads to intraoperative difficulties during LC. Materials and Methods: Study design: A prospective randomized comparative study. Study period: July 2022–December 2023 (18 months). Study groups: Group H = Patients with history of (H/O) intake of homeopathic medicines for treatment of cholelithiasis = 60 patients, Group N = Patients with no H/O homeopathic medicine intake = 60 patients. Results: Twenty-six (43.33%) patients in Group H and 11 (18.33%) patients in Group N had a difficult LC. 7 (11.67%) patients in Group H and 1 (1.67%) patient in Group N had dense adhesions around the gallbladder (GB). 13 (21.67%) patients of Group H and 3 (5%) patients of Group N had a Frozen Calot’s Triangle (fibrosis and difficult Calot’s triangle dissection). This was statistically significant. Conclusion: Our study proved that intake of homeopathic medications for the treatment of cholelithiasis leads to dense adhesions around GB as well as fibrotic adhesions leading to difficult Calot’s triangle dissection leading to a difficult LC.

Predictive Factors for Difficult Laparoscopic Cholecystectomies in Acute Cholecystitis

Laparoscopic cholecystectomy (LC) is the gold standard treatment in acute cholecystitis. However, one in six cases is expected to be difficult due to intense inflammation and suspected adherence to and involvement of adjacent important structures, which may predispose patients to higher risk of vascular and biliary injuries. In this study, we aimed to identify the preoperative parameters with predictive value for surgical difficulties. A retrospective study of 255 patients with acute cholecystitis admitted in emergency was performed between 2019 and 2023. Patients in the difficult laparoscopic cholecystectomy (DLC) group experienced more complications compared to the normal LC group (33.3% vs. 15.3%, p &lt; 0.001). Age (p = 0.009), male sex (p = 0.03), diabetes (p = 0.02), delayed presentation (p = 0.03), fever (p = 0.004), and a positive Murphy sign (p = 0.007) were more frequently encountered in the DLC group. Total leukocytes, neutrophils, and the neutrophil-to-lymphocyte ratio (NLR) were significantly higher in the DLC group (p &lt; 0.001, p = 0.001, p = 0.001 respectively). The Tongyoo score (AUC ROC of 0.856) and a multivariate model based on serum fibrinogen, thickness of the gallbladder wall, and transverse diameter of the gallbladder (AUC ROC of 0.802) showed a superior predictive power when compared to independent parameters. The predictive factors for DLC should be assessed preoperatively to optimize the therapeutic decision.

Scale and Safety: Analyzing the Association Between Intraoperative Difficulty and Achieving the Critical View of Safety in Laparoscopic Cholecystectomy.

Laparoscopic cholecystectomy (LC) is the preferred method for gallstone removal, but bile duct injuries remain a concern. Achieving the critical view of safety (CVS) is pivotal in preventing such injuries. The aim of this study was to compare the rates of difficult LC in those with CVS achieved compared to those with CVS not achieved. We performed a single-center prospective study on all patients with ultrasound-confirmed symptomatic gallstones. Patients were excluded if they refused to consent or if they underwent LC for indications other than gallstone disease. Patients were stratified into two groups as CVS not achieved and CVS achieved groups and compared for outcomes. Our primary outcome was the rate of intraoperative difficulty on the modified Nassar scale (MNS). Statistical analysis was performed using SPSS version 25.0 (IBM Corp., Armonk, NY). We included 70 patients who underwent LC for gallstones (CVS not achieved = 24 and CVS achieved = 46). The mean (SD) age was 42.2 (12.3) years, and 73.5% were females. The mean (SD) weight in our study cohort was 74.1 (10.9) kg, and there was no difference between the two groups in terms of the baseline demographic characteristics, disease characteristics, and comorbid conditions (p > 0.05). On univariate analyses, achieving CVS was associated with lower rates of higher-grade operative difficulty on the MNS and lower rates of length of stay of more than one day. Achieving CVS is associated with easy LC based on significantly lower Nassar scores. These findings highlight the role of the MNS in the successful identification of the operative difficulty of LC and its correlation with achieving CVS.
