Initial experience with laparoscopic posterior retroperitoneal adrenalectomy in single tertiary center

Purpose@#Laparoscopic posterior retroperitoneal adrenalectomy (LPRA) is a surgical method that accesses the adrenal gland through the back. The aim of this study was to report initial experience of LPRA and evaluate possibilities for surgical application. @*Methods@#From March 2018 to December 2019, a total of 30 consecutive patients diagnosed with adrenal tumor underwent surgical treatment at Pusan National University Hospital were enrolled. Clinicopathologic features and various peri- and postoperative parameters were analyzed by retrospective medical record review. The mean age of the patients was 48.20 ± 13.66 years. @*Results@#The mean body mass index (BMI) was 25.50 ± 4.30 kg/m2 . Primary hyperaldosteronism was the most frequently preoperative diagnosed disease (n = 13, 43.4%), followed by adrenal incidentaloma (n = 8, 26.6%), Cushing syndrome (n = 5, 16.6%) and pheochromocytoma (n = 4, 13.3%). The mean size of postoperative adrenal tumor was 2.72 ± 1.76 cm. The mean operating time was 162 ± 58.14 minutes. Among the 30 patients, 28 patients underwent total adrenalectomy (93.3%) and two patients underwent cortical sparing adrenalectomy (6.7%). When LPRA was performed for patients with BMI > 23.16 kg/m2 , the operating time was longer than the average (P = 0.016). @*Conclusion@#LPRA was suitable and safe for patients with benign adrenal tumors. BMI, retroperitoneal fat density and postoperative adrenal weight may be related to the operating time, so they should be considered when deciding on a surgical method for adrenalectomy.

Influence of Infrapopliteal Runoff Vessels on Primary Patency after Superficial Femoral Artery Angioplasty with Stenting in Patients with Claudication

Purpose@#The number of infrapopliteal runoff vessels seems to be one of the factors influencing arterial patency in patients who had undergone superficial femoral artery (SFA) angioplasty with stenting. However, the effectiveness of infrapopliteal runoff vessels in predicting patency during SFA angioplasty remains unclear. This study aimed to determine whether the number and quality of infrapopliteal runoff vessels affect the primary patency after SFA angioplasty with stenting in patients with claudication. @*Materials and Methods@#This study reviewed a retrospective database of patients with claudication who underwent SFA angioplasty with stenting between March 2011 and December 2016. The preoperative computed tomography findings of all patients were reviewed to assess infrapopliteal runoff vessels. The Trans-Atlantic Inter-Society (TASC) II classification and modified Society for Vascular Surgery (SVS) runoff score were used for subsequent analysis. Kaplan–Meier survival curves were constructed, and Fisher’s exact and chi-square tests were used for data analysis. @*Results@#A total of 153 limbs of 122 patients (88.2% male, mean age: 69.1 years) underwent SFA angioplasty with stenting. The overall primary patency rates of TASC II A/B and C/D cases were 77.1% and 31.2%, respectively, at 36 months (P<0.001). The primary patency rates at 36 months using the modified SVS runoff scoring system were 64.6% and 49.8% for the good-to-compromised (≤9 points) and poor (≥10 points) runoff groups, respectively (P=0.011). @*Conclusion@#The modified SVS runoff scoring system is effective in predicting primary patency after SFA angioplasty with stenting in patients treated for claudication.

Transanal Minimally-Invasive Surgery for Treating Patients With Regressed Rectal Cancer After Preoperative Chemoradiotherapy

PURPOSE: Although the standard treatment for patients with locally advanced rectal cancer managed by preoperative chemoradiotherapy (CRT) is a radical resection, local excisions are used in highly-selective cases. Recently, transanal minimally-invasive surgery (TAMIS) has emerged as a feasible technique for local excision of midrectal lesions. We assess the feasibility of using TAMIS to treat patients with locally advanced rectal cancer who showed good response to CRT. METHODS: From October 2010 to June 2013, 35 consecutive patients with rectal cancer managed by using preoperative CRT underwent TAMIS. After a single-incision laparoscopic surgery port had been introduced into the anal canal, a full-thickness local excision with conventional laparoscopic instruments was performed. We retrospectively reviewed a prospectively collected database of these cases. RESULTS: Of the 35 patients analyzed, 18 showed pathologic complete responses and 17 had residual lesions (2 ypTis, 4 ypT1, 9 ypT2, and 2 ypT3); 34 (97.1%) showed clear deep, lateral margins. The median distance of lesions from the anal verge was 5 cm. All procedures were completed laparoscopically, and the median operating time was 84 minutes. No intraoperative events or morbidities were seen in any of the patients, except one with wound dehiscence, who was treated conservatively. The median postoperative hospital stay and follow-up period were 4 days and 36 months, respectively. During the study period, no patients died, but 5 (14.3%) experienced recurrence, including one recurrence at the TAMIS site. CONCLUSION: TAMIS seems to be a feasible, safe modality for treating patients with locally advanced rectal cancer who show good response to preoperative CRT.

Matched case-control analysis comparing oncologic outcomes between preoperative and postoperative chemoradiotherapy for rectal cancer

PURPOSE: To investigate patterns of recurrence and oncologic outcomes after recurrence between preoperative and postoperative chemoradiotherapy (CRT). METHODS: Records of patients with stage II or III locally advanced rectal cancer seen between January 2000 and December 2010 were analyzed. The outcomes for patients undergoing preoperative CRT followed by radical resection (n = 466) were compared with outcomes of patients matched for sex, age, and stage who had surgery and then postoperative CRT (n = 466). Recurrence rates and sites, treatment of recurrence, and oncologic outcomes after recurrence were investigated. The rate of sphincter preservation and permanent stoma formation were also evaluated. RESULTS: Recurrence occurred in 124 and 140 patients in the pre- and postoperative CRT groups, respectively. The local and systemic recurrence rates were 3.6% and 20.8%, respectively, in the preoperative CRT group and 3.0% and 25.3%, respectively, in the postoperative CRT group (P = 0.245). Time to recurrence was longer in the postoperative CRT group (19 months vs. 24.2 months, P = 0.029). The overall rates of sphincter preservation (sphincter preservation operation and postoperative permanent stoma formation) did not significantly different between the two groups (P = 0.381). The 5-year overall survival rate after recurrence did not differ between the two groups (25.6% vs. 18.6%, P = 0.051). CONCLUSION: Preoperative and postoperative CRT are both safe and suitable treatment methods for rectal cancer, so the choice can be tailored to the patient's situation.

Comparison of long-term oncologic outcomes between radiofrequency ablation and surgical resection for metachronous isolated hepatic metastases from colorectal cancer

PURPOSE: We compared oncologic outcomes between surgery and radiofrequency ablation (RFA) in patients with metachronous isolated hepatic metastases from colorectal cancer.METHODS: We retrospectively analyzed 123 patients treated with hepatic resection and 82 patients treated with RFA for metachronous hepatic metastases between April 2000 and October 2011. Re-recurrence pattern and 3-year re-recurrence free survival (RFS) rate compared between groups. Factors associated with RFS were evaluated.RESULTS: The patients in the two groups were similar in age, gender, location of primary tumor, disease-free interval to hepatic metastasis, pathological stage of primary disease, number of metastatic lesions. The mean diameter of the biggest hepatic metastatic lesion was significantly larger in the resection group than in the RFA group. The RFS rate after hepatic metastasis treatment was significantly higher in the resection group than in the RFA group (48.6% vs. 33.7%, respectively; P=0.015). Marginal recurrence at the RFA site was observed in 14 of the 82 patients (17.1%). The size and number of metastatic lesions, stage of primary disease, disease-free interval to hepatic metastasis, and modality of treatment were confirmed as re-recurrence-associated factors after hepatic metastasis treatment. Among patients with solitary metastases of ≤3 cm, the RFS rate was not different between the resection and RFA groups (52.4% vs. 53.4%, respectively; P=0.491).CONCLUSION: Surgical resection for metachronous hepatic metastases achieved higher RFS and lower local recurrence rates. However, the RFS rate in patients with a solitary hepatic metastasis of ≤3 cm was similar between the resection and RFA groups.

Non-invasive ventilation for surgical patients with acute respiratory failure / 대한외과학회지

PURPOSE: Acute respiratory failure is a relatively common complication in surgical patients, especially after abdominal surgery. Non-invasive ventilation (NIV) is increasingly used in the treatment of acute respiratory failure. We have assessed the usefulness of NIV in surgical patients with acute respiratory failure. METHODS: We retrospectively reviewed the medical charts of patients who were admitted to a surgical intensive care unit between March 2007 and February 2008 with acute respiratory failure. The patients who have got respiratory care for secondary reason such as sepsis and encephalopathy were excluded from this study. RESULTS: Of the 74 patients who were treated with mechanical ventilation, 15 underwent NIV and 59 underwent invasive ventilation. The causes of acute respiratory failure in the NIV group were atelectasis in 5 patients, pneumonia in 5, acute lung injury in 4, and pulmonary edema in 1, this group included 3 patients with acute respiratory failure after extubation. Overall success rate of NIV was 66.7%. CONCLUSION: NIV may be an alternative to conventional ventilation in surgical patients with acute respiratory failure. Use of NIV may avoid re-intubation in patients who develop respiratory failure after intubation.

Revision Anterior Cruciate Ligament Reconstruction Using Two Anteromedial Portal Technique / 대한스포츠의학회지

There are numerous reasons for the failure of anterior cruciate ligament (ACL) reconstruction. Among them, surgical technical failure and wrong femoral tunnel location are the most common. The authors focused on the results of ACL revision using two anteromedial portals. Sixteen patients were selected with two anteromedial portals that were designed to decrease the femoral tunnel slope in sagittal plane. Clinical analysis was carried out based on Lysholm score, Tegner score and International Knee Documentation Committee (IKDC). For anterior stability test, Lachman test, KT-2000 arthrometer were used. pivot shift test was measured for rotatory stability test. Preoperative Lachman test and pivot shift test showed positive finding in all cases, however, postoperative Lachman with 10 cases (62.5%) and pivot shift test with 10 cases (62.5%) were negative. The difference of anterior displacement with the non-affected side using KT 2000 arthrometer showed 6.57 mm (range: 4.0-12.0 mm) preoperatively and 2.20 mm (range: 1.0-4.0 mm) postoperatively on average. Score of Tegner and Lysholm improved from 4.86 (range: 2.0-7.0), 46.14 (range: 33-52) preoperatively, to postoperative score of 8.14 (range: 7.0-9.0), 83.43 (range: 74-89) at the final follow up. IKDC result also showed improvement. ACL reconstruction method using two anteromedial tunnels that is desgined to decrease femoral tunnel slope at sagittal plane is an effective technigue for revision surgery after initial ACL reconstruction failure. This technigue allows superior femoral tunnel selection, firm fixation of grafts and also shows excellent clinical results with stability.

Extremity Operation by a Use of Fibrin Sealant in Burn Patient

PURPOSE: The surgical treatment of burn patient is associated with substantial blood loss. Therefore, multiple hemostatic techniques have been proposed for this problem. Unfortunately, a clear conclusion as to the best hemostatic agent cannot be made. Then, we present our experience of using Fibrin sealant (TISSEEL(TM)) in extremity operation. METHODS: We reviewed the medical records of 10 patients treated in our burn center who conducted the extremity operation using Fibrin sealant from January 2010 to December 2010. RESULTS: The mean tourniquet time is within 60 minutes and no need of transfusion during the operation in all patients. The average take rate for skin graft is over the 98%. No one has nerve injury and other problems. CONCLUSION: Fibrin sealant is a human derived factors that are designed to reproduce the final step of the physiologic coagulation cascade of a stable fibrin clot. In addition, Fibrin sealant has the advantage of being biocompatible and biodegradable, without inducing inflammation, foreign body reaction, and tissue necrosis. Fibrin sealant is shown to be effective methods to achieve hemostasis for the extremity burn surgery.

Group Education Program on Quality of Life of Burn Rehabilitation Patients

PURPOSE: This study was designed to compare the quality of life and physical function after group education program in burn rehabilitation program. METHODS: In a prospective clinical trial, group rehabilitation education program was done in 20 burn injury patients. One group pretest-post test design was done. After 2 weeks group education session, we measured stress test, quality of life (Burn specific health scale) and range of motion. Stress status was assessed with objective measurement tools such as heart rate variability. RESULTS: Stress resistance and parameter value was changed significantly (P0.05). CONCLUSION: Group therapy in burn rehabilitation patients could be an alternative rehabilitation treatment for quality of life. In the future, more studies are yet to come how group education program may affect the burn rehabilitation patients' disability.

Effect of Laughter Therapy on Recovery of Facial Burn Scar

PURPOSE: To compare the scar formation after laughter therapy in facial burn scar and to make facial burn rehabilitation program. METHODS: In a prospective clinical trial, laughter therapy was done in 12 facial burn injury patients. One group pretest-posttest design was done. After 8 weeks group laughter therapy session, we measured scar condition. Facial burn scar were checked. Scars were assessed with objective measurement tools such as pigmentation, erythema, pliability, transepidermal water loss, thickness and perfusion. RESULTS: Pigmentation value was decreased significantly: 211.6+/-71.9 to 177.8+/-57.1 (p0.05). Transepidermal water loss value changed from 40.7+/-15.9 g/h/m2 to 37.8+/-15.4 g/h/m2 (p>0.05). Microcirculation value was decreased significantly (0.80+/-0.05 volt to 0.43+/-0.19 volt)(p<0.05). Skin elasticity level (R0) was significantly increased (p<0.05). CONCLUSION: Laughter therapy in burn patients could be an alternative treatment to control burn scar contracture. In the future, more studies are needed how laughter therapy may affect the skin condition of the burn injuries.

Incidence of Candidemia and Related Mortality Following Severe Burns

PURPOSE: Severe burn patients are easily exposed to infection due to immune compromise and loss of skin barrier. But in spite of advances in burn treatment, complication due to infection has significant influence in mortality and morbidity. Broad spectrum antibiotics are used empirically to reduce bacterial infection in severe burn patients but results in suppression of normal flora and mucosal damage in intestine which facilitates fungal growth. We investigated the incidence, frequent onset time, characteristics of patients with candidemia and found appropriate time for use of antifungal agents and treatment of infection. METHODS: We reviewed the medical records of patients who were admitted to Hangang sacred heart hospital burn ICU between January 2007 and December 2008. RESULTS: In 2007 395 patients were admitted to BICU and 66 patients (16.7%) had fungal infection. In 2008 331 patients were admitted to BICU and 77 patients (23.3%) had fungal infection. Fungus was isolated in blood culture in 22 patients (5.6%) and 7 patients (2.1%) in 2007 and 2008 respectively. 20 patients out of 28 patients with candidemia received ventilator care (p=0.037), mean stay in ICU was 52.2 days in patients with positive blood culture compared with 36.5 days in patients with negative blood culture (p=0.049). Mortality in candidemia patients was 42.9% (p=0.022) which was high. CONCLUSION: Candidemia frequently occurs in patients receiving ventilator care, and as stay in ICU lengthens financial burden increases and results in higher mortality and morbidity. Lowering morbidity through strict infection control and monitoring is needed.

A Case of Weil's Disease associated with Acute Pancreatitis / 감염과화학요법

Leptospirosis is a zoonotic disease of worldwide distribution that is caused by spirochetes known as Leptospira; more than 20 serogroups and more than 200 serovars are known. The disease has seasonal incidence occurring in the late summer or early fall. The typical severe case of leptospirosis is known as Weil's disease; it is characterized by hepatic and renal involvement and is common in Korea. Elevated amylase can be seen when ARF is associated but true acute pancreatitis is an uncomon complication of leptospirosis and only seven cases of well documented pancreatitis have been described abroad, with there was no case report in Korea yet. We experienced a 55-year old male patient who had Weil's disease associated with acute pancreatitis which was confirmed by elevated amylase and lipase with pancreatic swelling and peripancreatic fat infiltration on abdomen CT.

Diagnostic Values of Serum and CSF CRP in Tuberculous Meningits

C-reactive protein(CRP) of the serurn and CSF vras quantitatively measured in patients who were diagnosed as tuberculous meningitis(19 cases), aseptic meningitis(44 cases) and control group(23 cases) in order to evaluate the diagnostic value and the possible dynarnics of CRP between serum and CSF. Following results were obtained. 1. Significant difference(p<0.005) OF CRP was observed in the initial CSF of the patients with tuberculous meningitis and aseptic meningitis. When the CRP of CSF was set above 0.4rng /dl, a sensitivity of 0 79 apd a specificity of 0.90 were obtained. 2. When the CRP in the initial serurn as compared, significant difference(p<0.0210) was also observed between the patients with tuberculous rneningitis and aseptic meningitis. However, serurn CRP were not diagnostic because of significant overlap between the tuberculous and the aseptic meningitis. 3. On follow up measurement of CRP, patients with tuberculous meningitis showed signihcant decrease in both serurn and CSF while patients with aseptic meningitis showed significant decrease only in the serum. 4. In both groups of patients with tuberculous meningitis and aseptic meningitis, CRP values in the CSF were closely correlated to those of the serum(Pearson's r=0.25326 p<0. 035, Pearson's r=0.4520 p<0.0000 respectively) Considering that the content of protein was also significantly(p<0.000) elevated in the patients with tuberculous meningitis and that the CRP ratio(Qcrp) was also significantly(p<0.0035) elevated in comparison to the controls, the increased CRP in the CSF of tuberculous meningitis is probably due to an increased simple diffusion through the blood-CSF barrier resulted from increased serurn CRP and through impairrnent of blood-CSF barrier.

A Case of Huntington's Chorea

This is a case report of 47 year-old male patient with Huntington's chorea. Huntington's chorea is a progressive neurodegenerative disorder with autosomal dominant inheritance. The first symptoms of Huntington's chorea usually occur in the fourth to fifth decade and the gene is complete penetrance. The disease is characterized by both progressive motor abnormality, typically chorea, and intellectual deterioration commonly accompanied by prominent psychiatric symptoms including severe depression. Although the prevalence of Huntington's chorea is only 5-10 in 100,000 in Europe, the reported cases are extremely rare in this country until now.
