RESUMEN
INTRODUCTION: Gallbladder cancer (GBC) is a rare malignancy in Western population with poor prognosis. This study aimed to investigate the trends in GBC incidence, treatment pattern, and survival in Finland. METHODS: Patients diagnosed with primary GBC in a geographically defined area (Southern Finland Regional Cancer Center) during 2006-2017 were identified. RESULTS: Final cohort included 270 patients with GBC. The incidence was 1.32/100,000 persons, and it decreased 6.8 cases per million personyears during the study period. One hundred fifty-one (56%) patients were diagnosed at Stage IV. Fifty-one patients (19%) underwent curative-intent resection with 96% R0-resection rate. The median overall survival was 7.1 months and 5-year overall survival 11.6% for all patients, and 67.7 months and 56.8% after curative-intent resection, respectively. No improvement was noted over time in overall survival in patients with GBC, or in subgroups of different stages of GBC. CONCLUSIONS: The incidence of GBC is slightly decreasing in Southern Finland, but survival has not improved over time.

INTRODUCTION: Recently new standards for reporting outcomes of bile duct injury (BDI) have been proposed. It is unclear how these treatment outcomes are reflected in quality of life (QOL). The aim of this study was to report outcomes and QOL after repair of major BDI and compare repairs by hepatobiliary surgeon to repairs by non-hepatobiliary surgeons. METHODS: This was a retrospective study of patients treated for major (Strasberg E-type) BDI after cholecystectomy at a tertiary hepatobiliary center. Outcomes were assessed using Cho-Strasberg proposed standards. QOL was assessed using Short Form Health Survey (SF-36) and the gastrointestinal QOL-index (GIQLI). Patients undergoing uneventful cholecystectomy matched by age, urgency, and duration of follow-up were used as controls. RESULTS: Fifty-two patients with major BDI treated between 2000 and 2016 were included (42% male, median age 53 years). Thirty-seven (71%) patients attained primary patency (29 (83%) if primarily operated by a hepatobiliary surgeon). Actuarial primary patency rate (grade A result) at 1, 3, and 5 years was 58%, 56%, and 53% in the whole cohort, and 83%, 80%, and 80% in patients primary treated by a hepatobiliary surgeon, respectively. At 3-year follow-up 6 (11.5%) patients obtained grade B, 10 (19.2%) grade C, and 7 (13.5%) grade D result. QOL was similar in patients with BDI and controls (median SF-36 physical component 51.7 and 53.6, p = 1.0, mental component 53.3 and 53.4, p = 1.0, GIQLI 109.0 and 123.0, p = 0.174, respectively) at median 90 (IQR 70-116) months from cholecystectomy. QOL was similar regardless of outcome grade. CONCLUSION: First attempt to repair a severe BDI should be undertaken by a hepatobiliary surgeon. However, long-term QOL is not affected even by severe BDI, and QOL is not associated with the grade of the outcome.

BACKGROUND: Three-dimensional (3D) laparoscopy improves technical efficacy in laboratory environment, but evidence for clinical benefit is lacking. The aim of this study was to determine whether the 3D laparoscopy is beneficial in transabdominal preperitoneal laparoscopic inguinal hernia repair (TAPP). METHOD: In this prospective, single-blinded, single-center, superior randomized trial, patients scheduled for TAPP were randomly allocated to either 3D or two-dimensional (2D) TAPP laparoscopic approaches. Patients were excluded if secondary operation was planned, the risk of conversion was high, or the surgeon had less than five previous 3D laparoscopic procedures. Patients were operated on by 13 residents and 3 attendings. The primary endpoint was operation time. The study was registered in ClinicalTrials.gov (NCT02367573). RESULTS: Total 278 patients were randomized between 5th February 2015 and 23rd October 2017. Median operation time was shorter in the 3D group (56.0 min vs. 68.0 min, p < 0.001). 10 (8%) patients in 3D group and 6 (5%) patients in 2D group had clinically significant complications (Clavien-Dindo 2 or higher) (p = 0.440). Rate of hernia recurrence was similar between groups at 1-year follow-up. In the subgroup analyses, operation time was shorter in 3D laparoscopy among attendings, residents, female surgeons, surgeons with perfect stereovision, surgeons with > 50 3D laparoscopic procedures, surgeons with any experience in TAPP, patients with body mass indices < 30, and bilateral inguinal hernia repairs. CONCLUSION: 3D laparoscopy is beneficial and shortens operation time but does not affect safety or long-term outcomes of TAPP.

BACKGROUND: While 3D laparoscopy increases surgical performance under laboratory conditions, it is unclear whether it improves outcomes in real clinical scenarios. The aim of this trial was to determine whether the 3D laparoscopy can enhance surgical efficacy in laparoscopic cholecystectomy (LCC). METHOD: This prospective randomized controlled study was conducted between February 2015 and April 2017 in a day case unit of an academic teaching hospital. Patients scheduled for elective LCC were assessed for eligibility. The exclusion criteria were: (1) planned secondary operation in addition to LCC, (2) predicted to be high-risk for conversion, and (3) surgeons with less than five previous 3D laparoscopic procedures. Patients were operated on by 12 residents and 3 attendings. The primary endpoint was operation time. All surgeons were tested for stereoaquity (Randot® stereotest). The study was registered in ClinicalTrials.gov (NCT02357589). RESULTS: A total of 210 patients were randomized; 105 to 3D laparoscopy and 104 to 2D laparoscopy. Median operation time as similar in the 3D and 2D laparoscopy groups (49 min vs. 48 min, p = 0.703). Operation times were similar in subgroup analyses for surgeon's sex (male vs. female), surgeon's status (resident vs. attending), surgeon's stereovision (stereopsis 10 vs. less than 10), surgeon's experience (performed 200 LCCs or below versus over 200 LCCs), or patient's BMI (≤ 25 vs. 25-30 vs. > 30). No differences in intra- or postoperative complications were noted between the 3D and 2D groups. CONCLUSION: 3D laparoscopy did not show any advantages over 2D laparoscopy in LCC.

BACKGROUND: Cholecystectomy is usually carried out for benign indications. Most perform routine histopathologic examination to detect incidental gallbladder cancer (GBC). METHODS: Cholecystectomies performed at four hospitals in the Helsinki Metropolitan Area during 2010-2012 were analyzed retrospectively. Patients with preoperative suspicion of neoplasia, active malignancy, or in whom cholecystectomy was performed as a secondary procedure were excluded. RESULTS: A total of 2034 cholecystectomies were included. In ten patients (0.5%), GBC was identified, each with an associated macroscopic finding, including local hardness (n = 1), a thickened wall (n = 5), acute inflammation and necrosis (n = 1), or suspected neoplasia (n = 3). No GBC was found in macroscopically normal gallbladders (n = 1464). Of the ten patients with GBC, five underwent subsequent liver resection, four had metastatic disease, and one had locally advanced inoperable disease. Three of the five patients who underwent liver resection were alive and disease-free at final follow-up (median 48 months). The remaining seven patients with GBC died of the disease, with a median survival of 14 months (range 10-48 months). CONCLUSIONS: Routine histopathologic examination of a macroscopically normal gallbladder does not improve diagnosis of GBC. A histopathological examination is, however, mandatory when a macroscopic abnormality is present.

Background: Antitumoral immune response has a crucial role in constraining cancer. However, previous studies on cholangiocarcinoma (CCA), a rare and aggressive cancer, have reported contradictory findings on the prognostic impact of tumor-infiltrating T-lymphocytes. We aimed to clarify the effect of tumor-infiltrating CD3+ and CD8+ lymphocytes and PD-1/PD-L1 expression on CCA prognosis. Methods: CD3+, CD8+, and PD-1+ lymphocyte densities, as well as PD-L1 expression rate were analyzed from stained tissue microarray samples from the tumor center and invasive margin of 47 cholangiocarcinomas. The association of CD3+ and CD8+ based Immune cell score (ICS) and its components with overall survival was evaluated, adjusting for age, sex, TNM stage, radicality of surgery, tumor location, and PD-L1 expression on immune cells. Results: Low ICS was a strong independent prognostic factor for worse overall survival (Hazard ratio 9.27, 95% confidence interval 2.72-31.64, P<0.001). Among the ICS components, high CD8+ lymphocyte infiltration at the tumor center had the most evident impact on patient outcome. PD-1 and PD-L1 expression on immune cells did not have a significant impact on overall survival alone; however, PD-L1 positivity seemed to impair survival for ICSlow subgroup. Conclusion: Identifying patient subgroups that could benefit from immunotherapy with PD-1/PD-L1 pathway blockade may help improve treatment strategies for this aggressive cancer. Our findings highlight the importance of evaluating the immune contexture in cholangiocarcinoma, as ICS serves as a strong independent prognostic and selective factor for patients who might benefit from immunotherapy.
