Acute Cholecystitis Due to Lactococcus lactis and Single-Center Experience With Infections Due to Lactococcus spp.

Background: Lactococcus species are used to ferment milk to yogurt, cheese, and other products. The gram-positive coccus causes diseases in amphibia and fish and is a rare human pathogen. Patients and Methods: A 51-year-old male underwent laparoscopic cholecystectomy for acute and chronic calculous cholecystitis. Lactococcus lactis was isolated from pus from his gallbladder empyema. Results: Our institutional database was searched for other cases of Lactococcus spp. infections and four patients (2 males, 2 females; aged 51, 64, 78, and 80 years) were identified during a four-year period. The three other patients had positive blood cultures associated with pneumonia, toxic megacolon, and severe gastroenteritis. All isolates were monocultures with Lactococcus lactis (2), Lactococcus garvieae (1) and Lactococcus raffinolactis (1). Two patients died related to their sepsis. We report the second case of cholecystitis involving Lactococcus. Conclusions: Lactococcus is a very rare pathogen mainly causing blood stream infections but needs to be considered to cause serious surgical infections in humans.

Application of 3-Step Laparoscopic Cholecystectomy in Acute Difficult Cholecystitis.

BACKGROUND: With the aging of the global population, the incidence rate of acute cholecystitis is increasing. Laparoscopic cholecystectomy is considered as the first choice to treat acute cholecystitis. How to effectively avoid serious intraoperative complications such as bile duct and blood vessel injury is still a difficult problem that puzzles surgeons. This paper introduces the application of laparoscopic cholecystectomy, a new surgical concept, in acute difficult cholecystitis. METHODS: This retrospective analysis was carried out from January 2019 to January 2021. A total of 36 patients with acute difficult cholecystitis underwent 3-step laparoscopic cholecystectomy. The general information, clinical features, surgical methods, surgical results, and postoperative complications of the patients were analyzed. RESULTS: All patients successfully completed the surgery, one of them was converted to laparotomy, and the other 35 cases were treated with 3-step laparoscopic cholecystectomy. Postoperative bile leakage occurred in 2 cases (5.56%), secondary choledocholithiasis in 1 case (2.78%), and hepatic effusion in 1 case (2.78%). No postoperative bleeding, septal infection, and other complications occurred, and no postoperative colon injury, gastroduodenal injury, liver injury, bile duct injury, vascular injury, and other surgery-related complications occurred. All 36 patients were discharged from hospital after successful recovery. No one died 30 days after surgery, and there was no abnormality in outpatient follow-up for 3 months after surgery. CONCLUSIONS: Three-step laparoscopic cholecystectomy seems to be safer and more feasible for acute difficult cholecystitis patients. Compared with traditional laparoscopic cholecystectomy or partial cholecystectomy, 3-step laparoscopic cholecystectomy has the advantages of safe surgery and less complications, which is worth trying by clinicians.

Preoperative difficulty factors in delayed laparoscopic cholecystectomy: Tokyo Guidelines 2018 surgical difficulty score analysis.

INTRODUCTION: Tokyo Guidelines 2018 (TG18) recommend early laparoscopic cholecystectomy (LC) for low-risk acute cholecystitis (AC); however, some patients undergo delayed LC (DLC) after conservative treatment. DLC, influenced by chronic inflammation, is a difficult procedure. Previous studies on LC difficulty lacked objective measures. Recently, TG18 introduced a novel 25 findings difficulty score, which objectively assesses intraoperative factors. The purpose of this study was to use the difficulty score proposed in TG18 to identify and investigate the predictors of preoperative high-difficulty cases of DLC for AC. METHODS: We retrospectively reviewed 100 patients with DLC after conservative AC treatment. The surgical difficulty of DLC was evaluated using a difficulty score. Based on previous studies, the highest scores in each category were categorized as grades A-C. RESULTS: The severity of AC was mild in 51 patients and moderate in 49. Surgical outcomes revealed a distribution of difficulty scores, with grade C indicating high difficulty, showing significant differences in operative time, blood loss, achieving a critical view of safety, bailout procedures, and postoperative hospital stay compared with grades A and B. Regarding the preoperative risk factors, multivariate analysis identified age >61 years (p = .008), body mass index >27.0 kg/m2 (p = .007), and gallbladder wall thickness >6.2 mm (p = .001) as independent risk factors for grade C in DLC. CONCLUSION: The difficulty score proposed in TG18 provides an objective framework for evaluating surgical difficulty, allowing for more accurate risk assessments and improved preoperative planning in DLC for AC.

Endoscopic Gallbladder Drainage: A Comprehensive Review on Indications, Techniques, and Future Perspectives.

In recent years, therapeutic endoscopy has become a fundamental tool in the management of gallbladder diseases in light of its minimal invasiveness, high clinical efficacy, and good safety profile. Both endoscopic transpapillary gallbladder drainage (TGBD) and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD) provide effective internal drainage in patients with acute cholecystitis unfit for cholecystectomy, avoiding the drawbacks of external percutaneous gallbladder drainage (PGBD). The availability of dedicated lumen-apposing metal stents (LAMS) for EUS-guided transluminal interventions contributed to the expansion of endoscopic therapies for acute cholecystitis, making endoscopic gallbladder drainage easier, faster, and hence more widely available. Moreover, EUS-GBD with LAMS opened the possibility of several cholecystoscopy-guided interventions, such as gallstone lithotripsy and clearance. Finally, EUS-GBD has also been proposed as a rescue drainage modality in malignant biliary obstruction after failure of standard techniques, with encouraging results. In this review, we will describe the TBGD and EUS-GBD techniques, and we will discuss the available data on clinical efficacy in different settings in comparison with PGBD. Finally, we will comment on the future perspectives of EUS-GBD, discussing the areas of uncertainty in which new data are more strongly awaited.

Preoperative difficulty assessment of interval laparoscopic cholecystectomy for gallstones.

BACKGROUND: Laparoscopic cholecystectomy is the gold standard treatment for benign gallbladder disease. However, few studies have reported the difficulty of interval cholecystectomy after cholecystitis because early cholecystectomy is recommended for acute cholecystitis. In this study, we evaluated the difficulties associated with interval cholecystectomy for cholecystitis with gallstones. METHODS: We retrospectively analyzed patients with gallstones who underwent interval laparoscopic cholecystectomy for cholecystitis at our institution between January 2012 and December 2021. Patients were classified into laparoscopic total cholecystectomy and bailout procedure groups depending on whether they were converted to a bailout procedure, and their characteristics and outcomes were subsequently compared. Additionally, a logistic regression analysis of the preoperative factors contributing to bailout procedure conversion was performed. RESULTS: Of the 269 participants, 39 converted to bailout procedure, and bile duct injury occurred in one case (0.4%). In patient characteristics comparison, patients in the bailout procedure group were significantly older, had more impacted stones, had higher post-treatment choledocholithiasis, had severe cholecystitis, and had a higher rate of percutaneous transhepatic gallbladder drainage. There were no differences in the bile duct injury or perioperative complications between the two groups. In logistic regression multivariate analysis of the factors contributing to the bailout procedure, post-treatment of choledocholithiasis (P < .001), impacted stone (P = .002), and age ≥71 (P = .007) were independent risk factors. CONCLUSION: Impacted stones and choledocholithiasis are risk factors for conversion to bailout procedure and high difficulty in interval cholecystectomy. For such patients, interval cholecystectomy should be performed cautiously.

A novel preoperative score to predict severe acute cholecystitis.

BACKGROUND: In a large multicenter trial, The Parkland Grading Scale (PGS) for acute cholecystitis outperformed other grading scales and has a positive correlation with complications but is limited in its inability to preoperatively predict high-grade cholecystitis. We sought to identify preoperative variables predictive of high-grade cholecystitis (PGS 4 or 5). METHODS: In a six-month period, patients undergoing cholecystectomy at a single institution with prospectively graded PGS were analyzed. Stepwise logistic regression models were constructed to predict high-grade cholecystitis. The relative weight of the variables was used to derive a novel score, the Severe Acute Cholecystitis Score (SACS). This score was compared with the Emergency Surgery Acuity Score(ESS), American Association for the Surgery of Trauma (AAST) preoperative score and Tokyo Guidelines (TG) for their ability to predict high-grade cholecystitis. Severe Acute Cholecystitis Score was then validated using the database from the AAST multicenter validation of the grading scale for acute cholecystitis. RESULTS: Of the 575 patients that underwent cholecystectomy, 172 (29.9%) were classified as high-grade. The stepwise logistic regression modeling identified seven independent predictors of high-grade cholecystitis. From these variables, the SACS was derived. Scores ranged from 0 to 9 points with a C statistic of 0.76, outperforming the ESS ( C statistic of 0.60), AAST (0.53), and TG (0.70) ( p < 0.001). Using a cutoff of 4 or more on the SACS correctly identifies 76.2% of cases with a specificity of 91.3% and a sensitivity of 40.7%. In the multicenter database, there were 464 patients with a prospectively collected PGS. The C statistic for SACS was 0.74. Using the same cutoff of 4, SACS correctly identifies 71.6% of cases with a specificity of 83.8% and a sensitivity of 52.2%. CONCLUSION: The Severe Acute Cholecystitis Score can preoperatively predict high-grade cholecystitis and may be useful for counseling patients and assisting in surgical decision making. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

Impact of the COVID-19 pandemic on outcomes of cholecystectomy for acute cholecystitis: a national cohort study.

BACKGROUND: The COVID-19 pandemic was associated with significant disruptions to healthcare provision globally and in Aotearoa New Zealand. It remains unclear how this disruption affected the surgical management of acute cholecystitis and whether there are ongoing impacts. METHODS: We conducted a secondary analysis of two multicentre cohort studies (CHOLECOVID and CHOLENZ) on patients who underwent cholecystectomy for acute cholecystitis. Participants were categorized into pre-pandemic (September-November 2019), pandemic (March-May 2020), and late-pandemic (August-October 2021) phases. Baseline demographics, clinical management, and 30-day postoperative complications were assessed between phases. Multivariable logistic regression was used to explore the impact of timing of operation on rates of hospital readmission and postoperative complications. RESULTS: 517 participants were included, of whom 85 (16%) were in the pre-pandemic-phase, 52 (10%) were in the pandemic phase, and 380 (73%) were in the late-pandemic phase. Pandemic and late-pandemic phase participants were more comorbid and had higher rates of obesity and deranged blood results than pre-pandemic. After multivariable adjustment, there were no differences in rates of hospital readmission or postoperative complications at 30-day follow-up across phases. CONCLUSION: The COVID-19 pandemic had minimal impacts on the provision of cholecystectomy for acute cholecystitis in Aotearoa New Zealand. However, patients managed during the COVID-19 pandemic were more comorbid and had higher rates of obesity and elevated inflammatory markers.

Acute cholecystitis, obesity, and steatohepatitis constitute the lethal triad for bile duct injury (BDI) during laparoscopic cholecystectomy.

OBJECTIVE: The most feared complication during laparoscopic cholecystectomy remains a bile duct injury (BDI). Accurately risk-stratifying patients for a BDI remains difficult and imprecise. This study evaluated if the lethal triad of acute cholecystitis, obesity, and steatohepatitis is a prognostic measure for BDI. METHODS: A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) registry was performed. All laparoscopic cholecystectomy cases within the main NSQIP database for 2012-2019 were queried. Two study cohorts were constructed. One with the lethal triad of acute cholecystitis, BMI ≥ 30, and steatohepatitis. The other cohort did not have the full triad present. Multivariate analysis was performed via logistic regression modeling with calculation of odds ratios (OR) to identify independent factors for BDI. An uncontrolled and controlled propensity score match analysis was performed. RESULTS: A total of 387,501 cases were analyzed. 36,887 cases contained the lethal triad, the remaining 350,614 cases did not have the full triad. 860 BDIs were identified resulting in an overall incidence rate 0.22%. There were 541 BDIs within the lethal triad group with 319 BDIs in the other cohort and an incidence rate of 1.49% vs 0.09% (P < 0.001). Multivariate analysis identified the lethal triad as an independent risk factor for a BDI by over 15-fold (OR 16.35, 95%CI 14.28-18.78, P < 0.0001) on the uncontrolled analysis. For the controlled propensity score match there were 29,803 equivalent pairs identified between the cohorts. The BDI incidence rate remained significantly higher with lethal triad cases at 1.65% vs 0.04% (P < 0.001). The lethal triad was an even more significant independent risk factor for BDI on the controlled analysis (OR 40.13, 95%CI 7.05-356.59, P < 0.0001). CONCLUSIONS: The lethal triad of acute cholecystitis, obesity, and steatohepatitis significantly increases the risk of a BDI. This prognostic measure can help better counsel patients and potentially alter management.

Early Versus Delayed Laparoscopic Cholecystectomy for Acute Cholecystitis: A Single Center Experience.

Introduction: Acute cholecystitis (AC) represents a public health problem, increasing hospitalization costs, especially determined by the surgical treatment of these patients. Laparoscopic cholecystectomy (LC) has become the therapeutic gold standard, the timing of the intervention: early (ELC) versus late (DLC), is still debated, impacting the results. The primary objective of the study was to compare postoperative outcomes between ELC and DLC. Secondary objectives assessed surgical outcomes from the pre-pandemic period with those from the Covid-19 pandemic. Material and methods: A retrospective observational study is presented of 266 patients diagnosed with AC who were admitted to Clinic I of General Surgery, County Emergency Clinical Hospital of T #226;rgu Mure #351;, from 2018 to 2022. They were classified into the ELC group ( 72 hours from the onset of symptoms) and DLC ( 72 hours from symptom onset) and were further stratified into prepandemic and pandemic cohorts. Data on clinical symptoms, paraclinical data, surgical details, and postoperative course were collected and analyzed. Discussion: The results confirm fewer conversions to open surgery and reduced hospitalization in the ELC group. The pandemic did not significantly alter the timing of surgeries or patient demographics. Conclusion: In conclusion, ELC for AC patients offers significant advantages, justifying its preference over DLC Despite the decrease in the incidence of AC hospitalizations during the pandemic, postoperative outcomes are comparable to those in the pre-pandemic period. Future multicenter studies are recommended for a broader analysis of the efficacy of laparoscopic surgery in emergency settings.

Outcomes after laparoscopic cholecystectomy in patients older than 80 years: two-years follow-up.

BACKGROUND: The laparoscopic cholecystectomy is the treatment of choice for patients with benign biliary disease. It is necessary to evaluate survival after laparoscopic cholecystectomy in patients over 80 years old to determine whether the long-term mortality rate is higher than the reported recurrence rate. If so, this age group could benefit from a more conservative approach, such as antibiotic treatment or cholecystostomy. Therefore, the aim of this study was to evaluate the factors associated with 2 years survival after laparoscopic cholecystectomy in patients over 80 years old. METHODS: We conducted a retrospective observational cohort study. We included all patients over 80 years old who underwent laparoscopic cholecystectomy. Survival analysis was conducted using the Kaplan‒Meier method. Cox regression analysis was implemented to determine potential factors associated with mortality at 24 months. RESULTS: A total of 144 patients were included in the study, of whom 37 (25.69%) died at the two-year follow-up. Survival curves were compared for different ASA groups, showing a higher proportion of survivors at two years among patients classified as ASA 1-2 at 87.50% compared to ASA 3-4 at 63.75% (p = 0.001). An ASA score of 3-4 was identified as a statistically significant factor associated with mortality, indicating a higher risk (HR: 2.71, CI95%:1.20-6.14). CONCLUSIONS: ASA 3-4 patients may benefit from conservative management due to their higher risk of mortality at 2 years and a lower probability of disease recurrence.

Textbook outcome in urgent early cholecystectomy for acute calculous cholecystitis: results post hoc of the S.P.Ri.M.A.C.C study.

INTRODUCTION: A textbook outcome patient is one in which the operative course passes uneventful, without complications, readmission or mortality. There is a lack of publications in terms of TO on acute cholecystitis. OBJETIVE: The objective of this study is to analyze the achievement of TO in patients with urgent early cholecystectomy (UEC) for Acute Cholecystitis. and to identify which factors are related to achieving TO. MATERIALS AND METHODS: This is a post hoc study of the SPRiMACC study. It´s a prospective multicenter observational study run by WSES. The criteria to define TO in urgent early cholecystectomy (TOUEC) were no 30-day mortality, no 30-day postoperative complications, no readmission within 30 days, and hospital stay ≤ 7 days (75th percentile), and full laparoscopic surgery. Patients who met all these conditions were taken as presenting a TOUEC. OUTCOMES: 1246 urgent early cholecystectomies for ACC were included. In all, 789 patients (63.3%) achieved all TOUEC parameters, while 457 (36.6%) failed to achieve one or more parameters and were considered non-TOUEC. The patients who achieved TOUEC were younger had significantly lower scores on all the risk scales analyzed. In the serological tests, TOUEC patients had lower values for in a lot of variables than non-TOUEC patients. The TOUEC group had lower rates of complicated cholecystitis. Considering operative time, a shorter duration was also associated with a higher probability of reaching TOUEC. CONCLUSION: Knowledge of the factors that influence the TOUEC can allow us to improve our results in terms of textbook outcome.

Percutaneous cholecystostomy in elderly patients with acute cholecystitis: a systematic review and meta-analysis.

Percutaneous cholecystostomy (PC) is often preferred over early cholecystectomy (EC) for elderly patients presenting with acute cholecystitis (AC). However, there is a lack of solid data on this issue. Following the PRISMA guidelines, we searched the Medline and Web of Science databases for reports published before December 2022. Studies that assessed elderly patients (aged 65 years and older) with AC treated using PC, in comparison with those treated with EC, were included. Outcomes analyzed were perioperative outcomes and readmissions. The literature search yielded 3279 records, from which 7 papers (1208 patients) met the inclusion criteria. No clinical trials were identified. Patients undergoing PC comprised a higher percentage of cases with ASA III or IV status (OR 3.49, 95%CI 1.59-7.69, p = 0.009) and individuals with moderate to severe AC (OR 1.78, 95%CI 1.00-3.16, p = 0.05). No significant differences were observed in terms of mortality and morbidity. However, patients in the PC groups exhibited a higher rate of readmissions (OR 3.77, 95%CI 2.35-6.05, p < 0.001) and a greater incidence of persistent or recurrent gallstone disease (OR 12.60, 95%CI 3.09-51.38, p < 0.001). Elderly patients selected for PC, displayed greater frailty and more severe AC, but did not exhibit increased post-interventional morbidity and mortality compared to those undergoing EC. Despite their inferior life expectancy, they still presented a greater likelihood of persistent or recurrent disease compared to the control group.

Endoscopic Gallbladder Stenting to Prevent Recurrent Cholecystitis in Deferred Cholecystectomy: A Randomized Trial.

BACKGROUND & AIMS: Endoscopic transpapillary gallbladder stenting (ETGS) has been proposed as one of the adjunctive treatments, apart from antibiotics, before surgery in patients with acute cholecystitis whose cholecystectomy could not be performed or was deferred. Currently, there are no comparative data on the outcomes of ETGS in those who receive and do not receive ETGS. We aimed to compare the rates of recurrent cholecystitis at 3 and 6 months in these 2 groups. METHODS: Between 2020 and 2023, eligible acute calculous cholecystitis patients with a high probability of common bile duct stone, who were surgical candidates but could not have an early cholecystectomy during COVID-19 surgical lockdown, were randomized into groups A (received ETGS) and B (did not receive ETGS). A definitive cholecystectomy was performed at 3 months or later in both groups. RESULTS: A total of 120 eligible patients were randomized into group A (n = 60) and group B (n = 60). In group A, technical and clinical success rates were 90% (54 of 60) and 100% (54 of 54), respectively. Based on intention-to-treat analysis, group A had a significantly lower rate of recurrence than group B at 3 months (0% [0 of 60] vs 18.3% [11 of 60]; P = .001). At 3-6 months, group A showed a nonsignificantly lower rate of recurrent cholecystitis compared to group B (0% [0 of 32] vs 10% [3 of 30]; P = .11). CONCLUSIONS: ETGS could prevent recurrent cholecystitis in acute cholecystitis patients with common bile duct stone whose cholecystectomy was deferred for 3 months. In those who did not receive ETGS, the majority of recurrences occurred within 3 months. (Thaiclinicaltrials.org, Number TCTR20200913001).

A Review on Endoscopic Management of Acute Cholecystitis: Endoscopic Ultrasound-Guided Gallbladder Drainage and Endoscopic Transpapillary Gallbladder Drainage.

A percutaneous cholecystostomy tube (PCT) is the conventionally favored nonoperative intervention for treating acute cholecystitis. However, PCT is beset by high adverse event rates, need for scheduled reintervention, and inadvertent dislodgement, as well as patient dissatisfaction with a percutaneous drain. Recent advances in endoscopic therapy involve the implementation of endoscopic transpapillary drainage (ETP-GBD) and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD), which are increasingly preferred over PCT due to their favorable technical and clinical success combined with lower complication rates. In this article, we provide a comprehensive review of the literature on EUS-GBD and ETP-GBD, delineating instances when clinicians should opt for endoscopic management and highlighting potential risks associated with each approach.

Outcomes of patients with gallbladder cancer presenting with acute cholecystitis.

The main purpose of this study is to explore the outcomes of patients found to have gallbladder cancer during investigation and diagnosis of acute cholecystitis. The incidence of primary gallbladder cancer co-existing in acute cholecystitis is not well defined in the literature, with anecdotal reports suggesting that they experience worse outcomes than patients with gallbladder cancer found incidentally. METHODS: A retrospective review of all patients with gallbladder cancer managed at the Canberra Health Service between 1998 and May 2022 were identified and reviewed. RESULTS: A total of 65 patients were diagnosed with primary gallbladder cancer during the study period with a mean age of 70.4 years (SD 11.4, range 59-81.8 years) and a female preponderance (74% versus 26%) with a ratio of 2.8. Twenty (31%) patients presented with acute calculus cholecystitis and were found to have a primary gallbladder cancer. This group of patients were older and predominantly female, but the difference was not statistically significant. The overall 5-year survival in the cohort was 20% (stage 1 63%, stage 2 23%, stage 3 16%, and stage 4 0%). There was no statistically significant difference in survival between those who presented with acute cholecystitis vs other presentations. CONCLUSIONS: A third of the patients with gallbladder cancer presented with acute cholecystitis. There was no statistically significant difference in survival in those with bile spillage during cholecystectomy as well those presenting with acute cholecystitis.

Image-guided percutaneous cholecystostomy: challenging the norms.

Image-guided percutaneous cholecystostomy (IGPC) is a widely recognized and regularly employed procedure in numerous institutions, serving as an indispensable cornerstone in the management of patients with acute cholecystitis. The most up-to-date literature has found that the transperitoneal route is at least as safe as the transhepatic route and that both the trocar and Seldinger techniques are equally safe and effective. The above novel insights may offer reassurance and alleviate concerns among operators performing IGPC by dispelling the fixation on previously established beliefs and thus providing flexibility, which lightens the load on the operator. Future studies could further investigate these findings and shed light on potential disparities in the safety and efficacy profiles associated with the subcostal and intercostal approaches, different drainage catheter sizes, and/or the impact of operator experience on complication rates.

Bailout Surgery for Difficult Gallbladders: Surgical Approach and Outcomes.

INTRODUCTION: Inflammation in acute cholecystitis may cause a cholecystectomy to be more challenging. Due to the difficult dissection, conversion to subtotal cholecystectomy via laparoscopic or open procedure may be required. This is done to reduce the risk of bile duct injury and hemorrhage. We sought to describe the incidence and risk factors, safety, morbidity, and outcomes associated with bailout procedures. METHODS: A single academic center, retrospective review of laparoscopic cholecystectomies that resulted in bailout procedures performed between January 2015 and December 2020. Data collected from the chart review included demographics, comorbidities, length of presenting symptoms, vital signs, laboratory and imaging, intraoperative findings, length of surgery, and outcome. RESULTS: A total of 1892 cholecystectomies were performed with 147 bailout procedures. For bailout 92 (63.4%) were converted to open, with 66% resulting in complete cholecystectomy. Hypertension and diabetes were the most common comorbidities. The median duration of symptoms was 4 days. Difficult anatomy in the hepatocystic triangle (66%) and dense adhesions (31%) were the most common reasons for bailout. The mean duration of surgery was 145.76 (SD 102.94) minutes. There were 2 bile duct injuries, both in open total cholecystectomy subgroup. Bile leak occurred in 23.8% with majority in subtotal cholecystectomy group. There was no difference in hospital length of stay, surgical site infection, or mortality among different bailout procedures. CONCLUSIONS: Subtotal cholecystectomy represents a safe alternative to total cholecystectomy during challenging cases to avoid damaging surrounding structures. The choice of laparoscopic or open subtotal approach is dependent on the surgeons' expertise.
