C-reactive protein level as a predictor of difficult emergency laparoscopic cholecystectomy

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

BACKGROUND

The predictors of difficulty performing laparoscopic cholecystectomy (LC) following percutaneous transhepatic gallbladder drainage (PTGBD) for grade II acute cholecystitis have not been clearly understood.

METHODS

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.

RESULTS

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 >154 mg/L, LC difficulty, blood loss, and operative time increased ( P <0.05, P =0.01, P =0.01, respectively) compared with CRP <154 mg/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).

CONCLUSIONS

CRP levels >154 mg/L and intervals between PTGBD and LC exceeding 35 days are associated with greater LC difficulty.

Role of C-Reactive Protein as a Predictor of Difficult Laparoscopic Cholecystectomy

INTRODUCTION

Cholelithiasis is one of the most common diseases encountered in gastroenterology. Laparoscopic cholecystectomy can be labelled as difficult if the surgery continues for more than 60 minutes or if the cystic artery is injured before ligation or clipping. Predicting difficult laparoscopic cholecystectomy can help the surgeon to be prepared for intraoperative challenges such as adhesions in triangle of Calot, injury to cystic artery or gall stone spillage; and improve patient counseling.

METHODS

In this cross-sectional study, we evaluated 269 patients with diagnosed cholelithiasis and planned for laparoscopic cholecystectomy in the general surgery department of Civil Hospital Karachi. After approval of the institution review board of the Civil Hospital, the data of all the patients was collected along with informed consent. The patients were selected via nonprobability, consecutive sampling.

RESULTS

The prevalence of difficult LC during procedure was 14.5% (39/269). Contingency table showed the true positive, negative and false positive and negative observation and using these observation to compute accuracy. Sensitivity, specificity, PPV, NPV and accuracy of serum c-reactive protein (CRP) in predicting the difficult laparoscopic cholecystectomy in patients of cholelithiasis was 87.2%, 97%, 82.9%, 97.8% and 95.5% respectively. Effect modifiers like age, gender and BMI were controlled by stratification analysis and observed that diagnostic accuracy was above 90% in all stratified groups as presented in the following tables. 175 (65.06%) of 279 patients were females indicating female predominance. In general, 41 patients (15.05%) had CRP serum levels greater than 11 mg/dL out of which 34 patients had to undergo difficult laparoscopic cholecystectomy (DLC), while 223 out of 228 patients with serum CRP levels of less than 11 mg/dL did not face any difficulty during their cholecystectomy. Similar results have been acquired across all age groups and both genders.

CONCLUSION

C Reactive Protein is a potent predictor of difficult laparoscopic cholecystectomy and its conversion preoperatively. Patients with preoperatively high C Reactive Protein CRP levels in serum have more chances of complication intraoperatively and increased chances of conversion from laparoscopic to open surgery. Preoperative C Reactive Protein (CRP) with values >11 mg/dL was associated with the highest odds of presenting difficult laparoscopic cholecystectomy (DLC) in our study. This value possesses good sensitivity, specificity, PPV, and NPV for predicting DLC in our population.

Sequential histologic evolution of gallbladder inflammation in acute cholecystitis over the first 10 days after onset of symptoms

BACKGROUND

The timing of cholecystectomy during acute cholecystitis (AC) is controversial, especially whether it is advisable to perform in patients with duration of symptoms between 3 and 10 days. The purpose of this study is to define clearly the sequential evolution of histological changes following symptoms onset to guide recommendations regarding timing of cholecystectomy.

METHODS

We identified patients with AC (2005-2018) who had cholecystectomy within 10 days of symptom onset of a first attack of AC. Histologic features of gallbladder injury including cellular and exudative inflammatory response to injury were determined on blinded pathologic slides.

RESULTS

One hundred and forty-nine patients were divided into three groups; early-who underwent cholecystectomy 1-3 days after symptom-onset, intermediate-4-6 days, and late-7-10 days. Key features of injury were necrosis and hemorrhage. A subgroup of patients in the early phase developed severe necrosis and hemorrhage of an extent associated with difficult cholecystectomy. Large spikes in extent of necrosis and hemorrhage occurred at 7-10 days. Major inflammatory responses to injury were eosinophilic and lymphocytic infiltration and early fibrosis.

CONCLUSIONS

Severe necrosis may develop rapidly and be present in the early period after symptom onset of AC. Cholecystectomy may be reasonable in some patients but by day 7-10, severe necrosis and hemorrhage may be expected to be present in most patients.

Emergency versus elective cholecystectomy: Experience at a university hospital in the Eastern Province, Saudi Arabia

BACKGROUND

Laparoscopic cholecystectomy (LC), the procedure of choice for treating most gallbladder pathology, has become the most trusted elective procedure for treating gallstone disease because of its effectiveness and safety. While the timing is an important factor in those cases, our aim in this study was to compare emergency and elective LC, determine the differences in postoperative complications, and assess the conversion rate to open cholecystectomy.

MATERIALS AND METHODS

This study included a total of 627 patients who had undergone laparoscopic cholecystectomy during 2017-2019 at King Fahd Hospital of the University (KFHU). Records of both emergency and elective cases were reviewed from Quadra-med (software package). All demographic data of the patients, presenting complaint, laboratory and inflammatory marker, type of the operation, intraoperative complications, procedure time, conversion rate from laparoscopic to open cholecystectomy, postoperative period, length of hospital stay, and pathological diagnosis were entered into an Excel sheet. The data was analyzed using SPSS 23.0. Qualitative variables were described as frequencies and percentages, and continuous variables were summarized with mean and standard deviation (SD). Chi-square test, t-test, and the Mann-Whitney U-test were applied to test for statistical significance at P ≤ 0.05.

RESULTS

The mean age for patients undergoing elective LC was 39.94 years (SD=13.56) whereas, mean age of patients undergoing emergency LC was 40.64 years (SD=13.02). About 71% of cases in elective LC group were females compared to 55% in the emergency LC group. There was a significant difference in C-reactive protein (CRP) in relation to the type of surgery where P < 0.05. Twelve (1.9%) patients had subtotal cholecystectomy and two cases converted from LC to open. There was a significant association between postoperative complication and the type of surgery. The length of hospital stay (LOS) was also found to be significantly more in patients having emergency LC (6.0 vs. 4.5 d; P < 0.05).

CONCLUSION

The relation between conversion to an open procedure and type of surgery (elective or emergency) in our study was nonsignificant. There was a significant association between preoperative CRP, postoperative complication, length of hospital stay, and type of surgery. Further multicenter studies are required for further investigation.

Maximum Diameter of the Gallbladder Determined Presurgically Using Computed Tomography as a Risk Factor for Difficult Emergency Laparoscopic Cholecystectomy in Patients With Mild to Moderate Acute Cholecystitis

BACKGROUND

Early or emergency laparoscopic cholecystectomy (LC) was recommended in the 2018 Tokyo Guidelines for patients with mild to moderate acute cholecystitis (AC). Although surgical difficulty is frequently encountered during these surgeries, risk factors for predicting surgical difficulties have not been fully investigated, especially based on computed tomography (CT) findings.

MATERIALS AND METHODS

We investigated 72 patients who underwent emergency LC with mild (n=45) to moderate (n=27) AC. Patients who previously underwent presurgical percutaneous or endoscopic biliary drainage were excluded from this study. Difficult LC was defined using any of the following surgical factors: surgical duration ≥180 minutes, blood loss ≥300 g, or a conversion to open cholecystectomy. Subsequently, several presurgical clinical factors were analyzed, including sex, age at surgery, experience of the surgeon, interval between symptom onset and surgery, body mass index, diabetes history, presurgical white blood cell count, and C-reactive protein level. Moreover, stones in the cystic duct or perigallblader fluid and the maximum thickness and diameter of the gallbladders were evaluated via presurgical CT. Finally, logistic regression analysis was performed to compare the relationship between surgical difficulty and each clinical factor.

RESULTS

The average age at surgery of the included patients was 60.3 (range: 25 to 88 y), surgical duration was 112.2 (range: 29 to 296 min), and surgical blood loss was 55.2 (range: 0 to 530 g). Furthermore, 4 (5.6%) had to undergo open cholecystectomy, whereas postsurgical complications occurred in 5 (6.9%) patients. In addition, the mean postsurgical admission duration was 7 (range: 3 to 63 d). Thus, 12 patients experienced difficult LC, whereas 60 experienced nondifficult LC. Of the evaluated clinical factors, patients who experienced difficult LC showed higher presurgical C-reactive protein levels (10.78 vs. 6.76 mg/dL, P=0.01) and wider gallbladder diameters (48.4 vs. 41.8 mm, P<0.01) than those who experienced nondifficult LC. By univariate logistic regression analysis, results also showed that patients with a maximum gallbladder diameter had a higher risk of experiencing difficulty during emergency LC (P=0.02). Moreover, the gallbladder diameter's cutoff value was 43 mm after the receiver operating characteristic curve analysis.

CONCLUSIONS

In patients with mild to moderate AC, emergency LC can safely be performed. However, performing LC might be technically difficult in patients with AC after the identification of severe gallbladder swelling during presurgical CT.

The Critical View of Safety in Laparoscopic Cholecystectomy: User Trends Among Residents and Consultants

BACKGROUND

The Critical View of Safety (CVS) aims at preventing bile duct injuries (BDIs) in laparoscopic cholecystectomy (LCC). This study investigated CVS utilization among surgeons.

METHODS

Photos from LCCs were scored for satisfactory CVS. Rates of satisfactory CVS, BDIs, and postoperative complications among residents and consultants were compared. A lecture on CVS was given halfway through the study.

RESULTS

The study comprised 1532 patients. Residents had higher rates of satisfactory CVS in elective LCCs compared with consultants (34.9% vs. 23.0%, P<0.001), but not in emergency LCCs (18.4% vs. 15.0%, P=0.252). No significant differences in BDIs or postoperative complications emerged between residents and consultants. After the lecture, elective LCCs were photographed more frequently (80.3% vs. 74.0%, P=0.032), but rates of satisfactory CVS, BDIs, and postoperative complications remained unchanged.

CONCLUSIONS

Utilization of CVS can be affected by a single lecture but affecting rates of satisfactory CVS may require stronger interventions.

Which Is More Effective: Laparoscopic or Open Partial Cholecystectomy?

Objective: In laparoscopic cholecystectomy, partial cholecystectomy is usually preferred when the anatomic exploration is not enough to prevent bile duct injury and other complications. Some surgeons choose laparoscopically to perform partial cholecystectomy, whereas others convert to open surgery. In this study, we aim to discuss and compare the effectiveness of laparoscopic partial cholecystectomy (LPC) and open partial cholecystectomy (OPC). Materials and Methods: The data of 4712 patients who underwent laparoscopic cholecystectomy between 2012 and 2020 were reviewed. A total of 98 patients who had partial cholecystectomy were included in the study. Patients were examined in two groups according to whether the procedure was open or laparoscopic. The first group of patients was named the OPC group (n = 52), and the second group of patients was the LPC group (n = 46). The data of the two groups were comparatively analyzed. Results: The mean operative time and the postoperative hospital stay, respectively, were 118.2 minutes and 4.8 days in the OPC group, and 87.3 minutes and 2.55 days in the LPC group (P < .005 and P = .005). It was found that wound infection decreased by 83.1% (P = .026; odds ratio [OR] = 0.169) in the LPC group compared with the OPC group, and the probability of developing incisional hernia decreased by 81.1% (P = .014; OR = 0.189). At least one complication was observed in 17 patients in the OPC group and in 7 patients in the LPC group (P = .045). The probability of developing complications in any patient was 63% lower in the LPC group (P = .049; OR = 0.370). Conclusions: The indications that cause the surgeon to perform partial cholecystectomy are inherently open to complications, regardless of the surgical technique used. However, the laparoscopic operation has advantages such as shorter operation time, shorter postoperative hospital stay, lower risk of wound infection and incisional hernia rate, and lower complication rate than the open procedure. However, if the team performing the surgery does not have enough experience, they should never hesitate to switch to open cholecystectomy.

Does the Surgeon's Caseload Affect the Outcome in Laparoscopic Cholecystectomy for Acute Cholecystitis?

BACKGROUND

This study investigated how annual caseloads and the surgeon's previous experience influence the outcome in laparoscopic cholecystectomy (LCC) for acute cholecystitis.

METHODS

A total of 892 patients treated in Helsinki University Hospital in 2013-2016 were retrospectively analyzed. Surgeons were compared regarding volume-over 5 LCCs for acute cholecystitis a year versus 5 or fewer LCCs a year, and experience-attendings versus residents.

RESULTS

High-volume surgeons (n=14) operated faster than low-volume surgeons (n=62) (91 vs. 108 min, P<0.001). Examining only procedures with an attending present, high-volume attendings (n=7) converted less (14.9% vs. 32.0%, P<0.001) and operated faster (95 vs. 110 min, P<0.001) compared with low-volume attendings (n=41). The results of residents did not significantly differ from the results of attendings.

CONCLUSIONS

Attending surgeons, performing >5 LCCs for acute cholecystitis a year, have shorter operative times and lower conversion rates.
