RÉSUMÉ

The laparoscopic pancreaticoduodenectomy (LPD), introduced by Gagner and Pomp in 1994, is typically done in high-volume centers due to its technical demands. Our methods aim to provide effective traction, enabling efficient surgery despite limited staffing. A retrospective analysis of 29 patients undergoing LPD by a single surgeon between September 2021 and December 2022 showed promising outcomes: median intraoperative bleeding of 425 mL, operation time of 505 minutes, and postoperative hospital stay of 10 days. With only one case requiring open conversion, our external retraction techniques demonstrate efficacy in overcoming challenges associated with manpower constraints, highlighting potential utility for surgeons in similar settings. We share LPD external retraction techniques and outcomes.

RÉSUMÉ

Cancer can induce hypercoagulability, which may lead to stroke. This occurs when tumor cells activate platelets as part of their growth and metastasis. Tumor cells activate platelets by generating thrombin and expressing tissue factor, resulting in tumor cell-induced platelet aggregation. Histopathological studies of thrombi obtained during endovascular thrombectomy in patients with acute stroke and active cancer have shown a high proportion of platelets and thrombin. This underscores the crucial roles of platelets and thrombin in cancer-associated thrombosis. Cancer-associated stroke typically occurs in patients with active cancer and is characterized by distinctive features. These features include multiple infarctions across multiple vascular territories, markedly elevated blood D-dimer levels, and metastasis. The presence of cardiac vegetations on echocardiography is a robust indicator of cancer-associated stroke. Suspicion of cancer-associated stroke during endovascular thrombectomy arises when white thrombi are detected, particularly in patients with active cancer. Cancer-associated stroke is almost certain when histopathological examination of thrombi shows a very high platelet and a very low erythrocyte composition. Patients with cancer-associated stroke have high risks of mortality and recurrent stroke. However, limited data are available on the optimal treatment regimen for stroke prevention in these patients. Thrombosis mechanism in cancer is well understood, and distinct therapeutic targets involving thrombin and platelets have been identified. Therefore, direct thrombin inhibitors and/or antiplatelet agents may effectively prevent stroke recurrence. Additionally, this strategy has potential benefits in cancer treatment as accumulating evidence suggests that aspirin use reduces cancer progression, metastasis, and cancer-related mortality. However, clinical trials are necessary to assess the efficacy of this strategy involving the use of direct thrombin inhibitors and/or antiplatelet therapies.

RÉSUMÉ

The application of minimally invasive surgery for gallbladder cancer (GBC) is yet controversial. This article discusses the techniques of laparoscopic and robotic extended cholecystectomy. A 69-year-old male diagnosed with cT1-2N0 GBC underwent laparoscopic surgery, and a 55-year-old male with cT2N1 GBC underwent robotic surgery after preoperative chemotherapy. Nonanatomical partial hepatectomy with lymphadenectomy was performed. Liver parenchymal dissection was performed using Cavitron Ultrasonic Surgical Aspirator laparoscopically and Maryland bipolar dissector and Harmonic scalpel robotically. The operation time was 180 and 220 minutes, and the estimated blood loss was 140 and 130 mL, respectively. The final pathologies were pT1bN0 and pT2aN1, for which patients received adjuvant chemotherapy. There was no evidence of recurrence at 33 and 18 months without complications. Both laparoscopic and robotic extended cholecystectomy can be safely performed with the robotic surgical system as an effective alternative for GBC requiring liver resection with radical lymphadenectomy

RÉSUMÉ

PURPOSE: To evaluate the outcomes of modified medial rectus (MR) resection using a lowered amount of MR resection for recurrent exotropia after bilateral lateral rectus (LR) recessions. METHODS: Fifty-six patients, who underwent MR resection from 2003 to 2017 for recurrent exotropia after bilateral LR recessions, were included. MR resection was performed using modified MR resection with a smaller amount of resection than the standard of 4 mm resection at 20 prism diopters (PD) of exotropia. Postoperative surgical results at 1 month, 6 months, 1 year and 2 years were classified as a success (5 PD esotropia [ET]-10 PD exotropia [XT]), overcorrection (>5 PD ET), and undercorrection (>10 PD XT). The clinical factors affecting surgical results at postoperative 6 month and 2 years were also evaluated. RESULTS: The success rate was 78.2% at postoperative 1 month and 87.5% at postoperative 6 months. The overcorrection rate was 21.8% and the undercorrection rate was 0% at postoperative 1 month. At postoperative 6 months, the overcorrection rate decreased to 0% and the undercorrection rate was 12.5%. The success rate was 85.7% at postoperative 1 year and 66.6% at postoperative 2 years. There was no clinical factor affecting the surgical outcomes except the ocular alignment at postoperative 1 month. The deviation at postoperative 1 month was more esotropic in patients with success at postoperative 6 months and 2 years than that in patients with undercorrection (p < 0.05). CONCLUSIONS: The modified MR resection showed favorable results of 87.5% at postoperative 6 months and 85.7% at 1 year. The angle of deviation at postoperative 1 month was an indicator of subsequent surgical outcomes.

RÉSUMÉ

PURPOSE: To evaluate the prognostic value of 18F-fluorodeoxyglucose positron-emission tomography (FDG PET) with computed tomography (CT) before and during radiotherapy (RT) in patients with head and neck cancer. METHODS: Twenty patients with primary head and neck squamous cell carcinoma were enrolled in this study, of whom 6 had oropharyngeal cancer, 10 had hypopharyngeal cancer, and 4 had laryngeal cancer. Fifteen patients received concurrent cisplatin and 2 received concurrent cetuximab chemotherapy. FDG PET/CT was performed before RT and in the 4th week of RT. The parameters of maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis (TLG) of the primary tumor were measured, and the prognostic significance of each was analyzed with the Cox proportional hazards model. RESULTS: Higher TLG (>19.0) on FDG PET/CT during RT was a poor prognostic factor for overall survival (OS) (p = 0.001) and progression-free survival (PFS) (p = 0.007). In the multivariate analysis, TLG during RT as a continuous variable was significantly associated with OS and PFS rate (p = 0.023 and p = 0.016, respectively). Tumor response worse than partial remission at 1 month after RT was another independent prognostic factor for PFS (p = 0.024). CONCLUSIONS: Higher TLG of the primary tumor on FDG PET/CT during RT was a poor prognostic factor for OS and PFS in patients with head and neck cancer.

RÉSUMÉ

PURPOSE: Use of radiotherapy combined with chemotherapy is increasing in hypopharyngeal cancer. However, many show residual tumor after radiotherapy. Timing for treatment evaluation and salvage therapy is essential. However, optimal timing for salvage surgery has not been suggested. In this study, we tried to evaluate optimal timing for salvage surgery. METHODS AND MATERIALS: Patients who were diagnosed with hypopharyngeal squamous cell carcinoma between 2006 and 2015 were retrospectively analyzed. All patients received definitive radiotherapy with or without chemotherapy. Response of all treated patients were analyzed at 1, 3, and 6 months after radiotherapy. Any patients with progression before 6 months were excluded. RESULTS: A total of 54 patients were analyzed. Complete remission (CR) rates at 1 month (CR1), 3 months (CR3) and 6 months (CR6) were 66.7%, 81.5%, and 90.7%, respectively. Non-CR at 1 month (NCR1), 3 months (NCR3), and 6 months (NCR6) showed poor locoregional recurrence-free survival rates (1-year rates of 63.7%, 66.7%, and 0.0%, respectively) compared to CR1, CR3, and CR6 (1-year rates 94.3%, 88.0%, and 91.5%, respectively). Particularly significant differences were seen between CR6 and NCR6 (p < 0.001). Of 10 patients with NCR3, 5 showed CR at 6 months (NCR3/CR6). There was no statistical difference in locoregional recurrence-free survival between CR3 and NCR3/CR6 group (p = 0.990). CONCLUSION: Our data suggest half of patients who did not show CR at 3 months eventually achieved CR at 6 months. Waiting until 6 months after radiotherapy may be appropriate for avoiding additional salvage therapy.

RÉSUMÉ

PURPOSE: To assess long-term changes in intraocular pressure (IOP) and the development of glaucoma after early phacoemulsification in acute primary angle closure. METHODS: Retrospective chart review of acute primary angle closure patients treated with phacoemulsification in attack eyes versus fellow eyes. Within a month after the angle closure attack, all subjects underwent cataract surgery and were divided into two groups: group A received cataract surgery on their attack eyes. Group B also received cataract surgery on their fellow eye after phacoemulsification of the attack eyes. Study outcomes were the prevalence of IOP rise (occurrence of IOP >21 mmHg) and the incidence of newly developed glaucoma. RESULTS: Eighty-nine eyes were included, with 62 attack eyes in group A and 27 fellow eyes in group B. Group A (14 eyes, 22.58%) had a higher cumulative rate of IOP rise than group B (3 eyes, 11.11%) at 12 months (p = 0.001). Newly developed glaucoma was not observed in group B; however, 6 patients in group A developed glaucoma during the 12-month follow-up period (p < 0.001). CONCLUSIONS: The attack eyes treated with phacoemulsification showed a significantly higher prevalence of IOP rise and newly developed glaucoma than fellow eyes that received phacoemulsification. These findings suggest that there is a possibility of IOP rise and development of glaucoma even when angle closure and successful IOP control have apparently been achieved after phacoemulsification.

RÉSUMÉ

BACKGROUND: Dense breast reduced the sensitivity of mammography in breast cancer screening and known as an independent risk factor of breast cancer. The relationship between breast density and age, body mass index has studied. However, there are few studies on the relationship between breast density and lifestyle related disease. In this study, we investigated the relationship between mammographic breast density and lifestyle related disease. METHODS: Retrospective cross sectional research was carried out from people who visited a single health screening center in Busan from January 2015 to December 2015. We investigated age, past history of the subjects and measured their height, weight, blood pressure and waist circumference. The biochemical test was carried out using their blood. All patients underwent mammography. The breast density on mammography determined by the basis of American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) breast composition and 996 people was recruited. RESULTS: In the distribution of breast density, 16.3% of women (n=160) had dense breast. Age (under 49), body mass index (BMI) (underweight) were positively correlated with the BI-RADS composition category 3, 4 but the number of lifestyle related disease were negatively correlated (age ρ=0.17, BMI ρ=0.39, the number of lifestyle related disease ρ=-0.21). The odds ratio (OR) of dense breast increased with decreasing lifestyle related disease severity (OR=3.06, 95% confidence interval: 1.13-8.22, P=0.027). CONCLUSIONS: This study showed that the number of lifestyle related disease was negatively correlated with mammographic density. The OR of dense breast increased with decreasing lifestyle related disease severity. Therefore, primary physicians should consider negative correlation between breast density and lifestyle related disease in breast cancer screening.

RÉSUMÉ

BACKGROUND/AIMS: The aim of this study was to evaluate the efficacy of high definition (HD) i-SCAN for colorectal polyp detection in screening colonoscopy. METHODS: We retrospectively analyzed the records of 501 patients who had undergone screening colonoscopy performed by three endoscopists with either HD i-SCAN (n=149) or standard white light (n=352) from January 2, 2014 through June 30, 2014. Patient information and inter-endoscopist variation as well as polyp number, endoscopic findings, and pathologic characteristics were reviewed. RESULTS: The detection rates of colorectal and neoplastic polyps were significantly higher using HD i-SCAN than standard white light colonoscopy (52% vs. 38.1%, p=0.004 for colorectal polyps; and 37.2% vs. 27.9%, p=0.041 for neoplastic polyps). Analysis of endoscopic findings revealed no difference in detected polyp size between HD i-SCAN and standard white light colonoscopy (4.59+/-2.35 mm vs. 4.82+/-2.81 mm, p=0.739), but non-protruding polyps were more commonly detected by i-SCAN than by standard white light colonoscopy (24.6% vs. 13.5%, p=0.007). CONCLUSIONS: Colonoscopy using HD i-SCAN had a significantly higher detection rate of colorectal polyps, including neoplastic polyps, because of improved sensitivity for detecting non-protruding lesions.

RÉSUMÉ

With the increase in life expectancy, age is no longer considered as a limitation for treatment. Nevertheless, the treatment of elderly patients with head and neck cancer (HNC) remains controversial. Here, we aimed to review our experience with the treatment for elderly patients, while particularly focusing on the differences among older old patients (septuagenarians vs. octogenarians). We retrospectively reviewed the records of 260 elderly patients who were assigned to 3 groups according to age: 70 years old ≤ group 1 < 75 years old, 75 years old ≤ group 2 < 80 years old, and group 3 ≥ 80 years old. The patients were assessed for comorbidities using the Adult Comorbidity Evaluation (ACE)-27, and the American Society of Anesthesia (ASA) physical status was also compared. Group 1, 2, and 3, consisted of 97, 102, and 61 patients, respectively. No significant difference in demographic data was noted among the groups. However, group 3 showed more comorbidities than groups 1 and 2. With regard to the initial treatment for HNC, radiation therapy (RT) was more frequently performed in group 3 than in groups 1 and 2. Among 7 patients of non-compliant to treatment in group 3, 6 patients had have performed RT. In group 3, a total of 18 patients underwent surgery, including microvascular free flap reconstruction and no significant difference in complications was observed postoperatively compared with group 1 and 2. Moreover, no significant difference was noted in overall survival between the groups, regardless of the treatment modality chosen. In conclusion, octogenarians with HNC should be more carefully managed than septuagenarians with HNC. Surgical treatment can be considered in octogenarians with HNC, if it can be tolerated.

RÉSUMÉ

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

RÉSUMÉ

PURPOSE: This study evaluates the long-term results of definitive radiotherapy (RT) for early glottic cancer. Clinical and treatment factors related to local control and patterns of failure are analyzed. MATERIALS AND METHODS: We retrospectively reviewed 222 patients with T1-2N0 squamous cell carcinoma of the glottic larynx treated with definitive RT from 1981 to 2010. None of the patients received elective nodal RT or combined chemotherapy. The median total RT dose was 66 Gy. The daily fraction size was < 2.5 Gy in 69% and 2.5 Gy in 31% of patients. The RT field extended from the hyoid bone to the cricoid cartilage. RESULTS: The median age was 60 years, and 155 patients (70%) had T1 disease. The 5-year rates of local recurrence-free survival (LRFS) and ultimate LRFS with voice preservation were 87.8% and 90.3%, respectively. T2 (hazard ratio [HR], 2.30; 95% confidence interval [CI], 1.08 to 4.94) and anterior commissural involvement (HR, 3.37; 95% CI, 1.62 to 7.02) were significant prognostic factors for LRFS. In 34 patients with local recurrence, tumors recurred in the ipsilateral vocal cord in 28 patients. There were no contralateral vocal cord recurrences. Most acute complications included grade 1-2 dysphagia and/or hoarseness. There was no grade 3 or greater chronic toxicity. CONCLUSION: Definitive RT achieved a high cure rate, voice preservation, and tolerable toxicity in early glottic cancer. T2 stage and anterior commissural involvement were prognostic factors for local control. Further optimization of the RT method is needed to reduce the risk of ipsilateral tumor recurrence.

RÉSUMÉ

OBJECTIVES: Metabolic acidosis frequently develops in patients after neobladder reconstruction. However, the incidence of metabolic acidosis in patients with neobladder and the factors associated with the development of metabolic acidosis have not been well elucidated. We aimed to investigate the incidence and the potential predictors for the development of metabolic acidosis after neobladder reconstruction with intestinal segment. METHODS: We included patients who underwent neobladder reconstruction using intestinal segment at Ewha Womans University Mokdong Hospital between January 1, 2005 and December 31, 2014. A subgroup of patients according to the time of metabolic acidosis occurrence was further analyzed in order to characterize predictors for metabolic acidosis. RESULTS: Metabolic acidosis was encountered in 79.4% of patients with neobladder during follow up period. When patients were divided into 2 groups according to anion gap (AG), total CO2 (18.9+/-2.1 mEq/L vs. 20.0+/-1.3 mEq/L, P=0.001) and chloride (106.6+/-4.9 mE/L vs. 109.4+/-3.6 mEq/L, P12 and AG< or =12. Furthermore, when patients were divided into 3 groups; patients with metabolic acidosis at postoperative day (POD) 1; from POD 2 to 14 days; after 14 days, there was significant difference among those subgroups. CONCLUSION: Our study showed the rate of metabolic acidosis in patients underwent neobladder reconstruction and the difference between patients with metabolic acidosis and those without metabolic acidosis for the first time in Korea. In the future, well designed prospective study will be needed to prevent metabolic acidosis after neobladder reconstruction.

RÉSUMÉ

PURPOSE: To evaluate the impact of adjuvant chemotherapy (AC) in patients with upper tract urothelial carcinoma and lymphovascular invasion (LVI) after radical nephroureterectomy (RNU). MATERIALS AND METHODS: We retrospectively analyzed the clinical records and clinicopatholgic outcomes of patients (n=552) treated with RNU between 1986 and 2013. Patients treated with neoadjuvant chemotherapy and those for whom LVI status was not recorded were excluded. Patients were divided into two groups according to LVI (n=86) or no LVI (n=256). RESULTS: The study included 344 patients (240 men and 104 women) with a median of 53.9 months of follow-up (range, 1-297 months) after RNU. Tumors were organ confined (T2/N0) in 211 (61.3%) and tumor grade high in 291 (84.6%). AC was administered in 64 patients (18.6%). A total of 280 patients (81.4%) were treated with surgery alone. Patients with LVI tended to be older (p=0.049), have a higher pT stage (pT3/T4, p<0.001), be pN+ (p<0.001), have a high tumor grade (p<0.001), and experience recurrence (p<0.001). In the multivariate analysis, LVI was an independent prognostic factor for cancer-specific survival and overall survival (p=0.002 and p<0.001, respectively). The multivariate analysis demonstrated that in the subgroup of patients with LVI, AC was a significant prognostic factor for cancer-specific survival and overall survival (hazard ratio, 0.51; p=0.027 and hazard ratio, 0.50; p=0.025, respectively). CONCLUSIONS: AC does not seem to reduce mortality in patients with advanced upper tract urothelial carcinoma after RNU. In the subgroup of patients with LVI, AC had a positive impact on cancer-specific survival and overall survival. LVI would be helpful for selecting patients who are appropriate for AC.

RÉSUMÉ

Robot-assisted laparoscopic radical cystectomy (RARC) for the treatment of muscle invasive bladder cancer is being increasingly applied. Radical cystectomy is complex procedure which should be performed with extensive lymph node dissection and urinary diversion. Currently, the techniques of RARC are well-described, and the feasibility and safety of RARC has been demonstrated. While extracorporeal approach is preferred method for urinary diversion, intracorporeal urinary diversion is gaining popularity. Positive surgical margins are similar to large open series but inferior for locally advanced disease. However, local recurrence and survival rates seem equivalent to open series at short and mid-term follow up. Randomized controlled trial should be conducted to rigorously assess the oncologic outcomes of RARC compared to open radical cystectomy.

RÉSUMÉ

Bladder cancer is the second most common malignancy in urological field. Most new cases are diagnosed as non-muscle invasive bladder cancer (NMIBC), which includes Ta, T1 or carcinoma in situ. Initial management of NMIBC is endoscopic resection, which allows both treatment and pathological staging. Urologist should consider adjuvant intravesical chemotherapy or Bacillus Calmette-Guerin (BCG) immunotherapy, depending on the tumor grade or stage to prevent recurrence and progression. Patients with muscle invasive bladder cancer (MIBC) are best treated with radical cystectomy. However, radical cystectomy should be considered even in patients with NMIBC with high risk of progression and BCG refractory tumors. Delay of radical cystectomy in these patients might lead decreased disease specific survival. Patients treated by radical cystectomy should undergo any form of the urinary diversion. Ileal conduit is still most common method for urinary diversion. Orthotopic neobladder is generally performed by experienced hands in high volume center. Patients undergoing orthotopic neobladder should be educated and manually skillful to manipulate their diversion. Neoadjuvant cisplatin-based chemotherapy is recommended based on level 1 evidence with survival benefit. Recent updated meta-analysis also demonstrated survival benefit in patients with MIBC treated by adjuvant chemotherapy.

RÉSUMÉ

Hypereosinophilic syndrome (HES) is characterized by persistent eosinophilia associated with damage to multiple organs. Although the diagnostic criteria for HES include sustained hypereosinophilia for at least 6 months, early initiation of therapy may be recommended in patients exhibiting HES symptoms. Eosinophilic enteritis has been reported as a cause of intussusception in several cases. However, HES as a cause of intussusception has not yet been reported. In the present report, we describe a case of HES that manifested as jejunojejunal intussusception. Although long-standing hypereosinophilia was not confirmed, the patient required eosinophil-lowering therapy for an intestinal obstruction. The patient was treated with systemic corticosteroids, after which the symptoms and multiple organ involvement, including intussusception, improved dramatically, as noted on the radiological investigation. Moreover, surgery was not necessary.
