BACKGROUND: Textbook outcome (TO) can guide decision-making among patients and clinicians during preoperative patient selection and postoperative quality improvement. We explored the factors associated with achieving a TO for gallbladder carcinoma (GBC) after curative-intent resection and analyzed the effect of adjuvant chemotherapy (ACT) on TO and non-TO patients. METHODS: A total of 540 patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Multivariable logistic regression was used to investigate the factors associated with TO. RESULTS: Among 540 patients with GBC who underwent curative-intent resection, 223 patients (41.3%) achieved a TO. The incidence of TO ranged from 19.0% to 51.0% across the study period, with a slightly increasing trend over the study period. The multivariate analysis showed that non-TO was an independent risk factor for prognosis among GBC patients after resection ( P = 0.003). Age ≤60 years ( P = 0.016), total bilirubin (TBIL) level ≤34.1 μmol/L ( P <0.001), well-differentiated tumor ( P = 0.008), no liver involvement ( P <0.001), and T1-2 stage disease ( P = 0.006) were independently associated with achieving a TO for GBC after resection. Before and after propensity score matching (PSM), the overall survival outcomes of non-TO GBC patients who received ACT and those who did not were statistically significant; ACT improved the prognosis of patients in the non-TO group ( P <0.05). CONCLUSION Achieving a TO is associated with a better long-term prognosis among GBC patients after curative-intent resection, and ACT can improve the prognosis of those with non-TO.

OBJECTIVE: To explore the value of micro-flow imaging (MFI) in evaluating blood flow characteristics and differential diagnosis of gallbladder polypoid lesions. METHODS: We retrospectively analyzed the clinical data and ultrasound images of 73 patients with gallbladder polypoid lesions, including 24 patients with pathologically confirmed neoplastic polyps (n=24) and 49 with non-neoplastic polyps (n=49). All the patients underwent conventional ultrasound, MFI and contrast enhanced ultrasound (CEUS) before cholecystectomy. The blood flow characteristics of the lesions in color Doppler flow imaging (CDFI) and MFI were compared, and the consistency of the findings by these two modalities with those of CEUS were evaluated by weighted Kappa consistency test. The diagnostic performance of MFI for gallbladder polypoid lesions was assessed. RESULTS: There were significant differences between MFI and CDFI in the evaluation of blood flow characteristics of gallbladder polypoid lesions (χ²=37.684, P < 0.001). MFI showed better performance than CDFI in displaying the blood flow characteristics of the polyps. The consistency in the findings was 0.118 between CDFI and CEUS and 0.816 between MFI and CEUS. The sensitivity, specificity and accuracy of MFI in distinguishing neoplastic polyps from non-neoplastic polyps were 75.00%, 93.88% and 87.67%, respectively. CONCLUSION MFI has a good consistency with CEUS in displaying the blood flow characteristics of gallbladder polypoid lesions and can accurately distinguish neoplastic polyps from non-neoplastic polyps, thus providing new ultrasound diagnostic evidence to support clinical decisions on optimal treatments of gallbladder polypoid lesions.

Objective: To study the impact of regional positive lymph node ratio (LNR) on prognosis of patients with gallbladder carcinoma. Methods: The clinicopathological and survival data of 53 patients with gallbladder carcinoma who underwent radical resection with regional lymph node metastasis in Ningbo University Affiliated Lihuili Hospital from May 2012 to December 2020 were collected, and receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of LNR for predicting postoperative survival status in patients with gallbladder carcinoma. According to the critical value, the patients were divided into low LNR group and high LNR group. The clinicopathological features and prognosis of the two groups were compared. Log rank test was used for univariate analysis of prognostic factors in patients with gallbladder carcinoma, and Cox proportional hazards model was used for multivariate analysis. Results: A total of 417 regional lymph nodes were dissected in 53 patients, of which 144 lymph nodes were positive, with a positive rate of 34.5%. The optimal cut-off value of LNR for predicting postoperative survival status of patients with gallbladder carcinoma was 0.33. According to this cut-off value, patients were divided into low LNR group (LNR≤0.33, 28 cases) and high LNR group (LNR>0.33, 25 cases). The recurrence rates were 64.3% (18/28) and 88.0 % (22/25) in low LNR group and high LNR group, respectively. The median recurrence-free survival (RFS) was 8 and 7 months, respectively (P=0.032). In the low LNR group, the 1-, 3-, and 5-year survival rates were 56.2%, 38.4%, and 32.0%, respectively, and the median overall survival (OS) was 16 months. In the high LNR group, the 1-, 3-, and 5-year survival rates were 37.9%, 5.4%, and 0, respectively, and the median OS was 9 months. The postoperative survival rate of patients in the low LNR group was better than that in the high LNR group (P=0.008). Univariate analysis showed that LNR was even associated with RFS and OS in patients with gallbladder carcinoma (P<0.05). Multivariate analysis showed that LNR>0.33 was an independent risk factor for postoperative RFS (HR=1.977, 95% CI: 1.045-3.740), but not for OS (HR=1.561, 95% CI: 0.685-3.553). Conclusion: On the basis of clearing a sufficient number of regional lymph nodes, patients with gallbladder carcinoma with regional LNR>0.33 are more likely to relapse after operation, but the predictive value of LNR>0.33 OS is insufficient.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) has become a more frequently performed method for benign gallbladder diseases all over the world. The effects of SILC technique on oxidative stress have not been well documented. The aim of this study was to evaluate the effect of laparoscopic cholecystectomy techniques on systemic oxidative stress by using ischemia modified albumin (IMA). METHODS: In total, 70 patients who had been diagnosed with benign gallbladder pathology were enrolled for this prospective study. Twenty-one patients underwent SILC and 49 patients underwent laparoscopic cholecystectomy (LC). All operations were performed under a standard anesthesia protocol. Serum IMA levels were analysed before operation, 45 minutes and 24 hours after operation. RESULTS: Demographics and preoperative characteristics of the patients were similiar in each group. The mean duration of operation was 37.5 ± 12.5 and 44.6 ± 14.3 minutes in LC and SILC group, respectively. In both groups, there was no statistically significant difference in hospital stay, operative time, or conversion to open surgery. Operative technique did not effect the 45th minute and 24th hour IMA levels. However, prolonged operative time (>30 minutes) caused an early increase in the level of IMA. Twenty-fourth hour IMA levels were not different. CONCLUSION: SILC is an effective and safe surgical prosedure for benign gallbladder diseases. Independent of the surgical technique for cholecystectomy, the prolonged operative time could increase the tissue ischemia.

BACKGROUND/AIMS: Extended cholecystectomy is generally recommended for patients with T2 gallbladder cancer. However, few studies have assessed the extent of resection relative to T2 gallbladder tumor location. This study analyzed the effects of surgical methods and tumor location on survival outcomes and tumor recurrence in patients with T2 gallbladder cancer. METHODS: Clinicopathological characteristics, extent of resection, survival rates, and recurrence patterns were retrospectively analyzed in 88 patients with pathologically confirmed T2 gallbladder cancer. RESULTS: The 5-year disease-free survival rate was 65.0%. Multivariate analysis showed that lymph node metastasis was the only independent risk factor for poor 5-year disease-free survival rate. Survival outcomes were not associated with tumor location. Survival tended to be better in patients who underwent extended cholecystectomy than in those who underwent simple cholecystectomy. Recurrence rate was not affected by surgical method or tumor location. Systemic recurrence was more frequent than local recurrence without distant recurrence. Gallbladder bed recurrence and liver recurrence were relatively rare, occurring only in patients with liver side tumors. CONCLUSIONS: Extended cholecystectomy is the most appropriate treatment for T2 gallbladder cancer. However, simple cholecystectomy with regional lymph node dissection may be appropriate for patients with serosal side tumors.

Gallbladder cancer (GBC) is the most common primary hepatobiliary carcinoma and the sixth most common gastrointestinal malignancy. Adenocarcinoma accounts for the vast majority of GBCs (80–95%), whereas squamous cell carcinoma constitutes only 0–3.3% of GBCs. A 69-year-old man was suspected to have GBC with a cholecystoduodenal fistula on an abdominal computed tomography scan. He underwent esophagogastroduodenoscopy, which revealed that the duodenum was obstructed by the mass. Duodenal and biliary stents were successfully placed using endoscopic retrograde cholangiopancreatography. Pathology obtained from the duodenum revealed the mass to be a squamous cell carcinoma.

Xanthogranulomatous inflammation (XGI) is characterized histologically by the deposition of foamy macrophages and infiltration of inflammatory cells. While XGI is extremely rare, it has been reported in the gallbladder, kidney, stomach, and lymph nodes. A 61-year-old woman presented with epigastric pain for 2 weeks. Abdominal computed tomography and magnetic resonance imaging showed a pancreatic head mass with distal common bile duct wall thickening. Endoscopic ultrasonography followed by fine needle aspiration was performed, and subsequent pathology report revealed a benign disease. Because uncontrolled abdominal pain persisted and possibility of malignancy could not be excluded, Whipple's operation was eventually performed, and pathology report showed xanthogranulomatous pancreatitis (XGP). Herein, we report a case of symptomatic XGP mimicking of pancreas cancer. Although XGP is extremely rare, it should be considered as a differential diagnosis of neoplastic lesions of the pancreas.

PURPOSE: The aim of this study was to investigate the risk factors for conversion to conventional laparoscopic cholecystectomy (CLC) in single incision laparoscopic cholecystectomy (SILC) along with the proposal for procedure selection guidelines in treating patients with benign gallbladder (GB) diseases. METHODS: SILC was performed in 697 cases between April 2010 and July 2014. Seventeen cases (2.4%) underwent conversion to conventional LC. We compared these 2 groups and analyzed the risk factors for conversion to CLC. RESULTS: In univariate analysis, American Society of Anesthesiologist score > 3, preoperative percutaneous transhepatic GB drainage status and pathology (acute cholecystitis or GB empyema) were significant risk factors for conversion (P = 0.010, P = 0.019 and P < 0.001). In multivariate analysis, pathology (acute cholecystitis or GB empyema) was significant risk factors for conversion to CLC in SILC (P < 0.001). CONCLUSION: Although SILC is a feasible method for most patients with benign GB disease, CLC has to be considered in patients with acute cholecystitis or GB empyema because it is likely to result in inadequate visualization of the Calot's triangle and greater bleeding risk.
