Gastrointestinal (GI) hemangiomas are relatively rare benign vascular tumors. The choice of an appropriate diagnostic method depends on patient age, anatomic location, and presenting symptoms. However, GI hemangiomas are not a common suspected cause of GI bleeding in children because of their rarity. Based on medical history, laboratory results, and imaging study findings, the patient could be treated with either medication or surgery. Herein, we report 3 cases of GI hemangioma found in the small bowel, rectum, and GI tract (multiple hemangiomas). Better knowledge and understanding of GI hemangioma could help reduce the delayed diagnosis rate and prevent inappropriate management. Although rare, GI hemangiomas should be considered in the differential diagnosis of GI bleeding.

PURPOSE: Endovascular therapy (ET) for peripheral arterial occlusive disease has increased dramatically in the past decade. ET is currently being performed by different specialists with available resources, with some of these resources being far superior to others, yet there have been no studies comparing the interventional outcomes according to the varying resources. The aim of this study was to analyze the outcomes of ET for superficial femoral artery (SFA) atherosclerosis using a mobile C-arm, in comparison to a historical control group. METHODS: Between March 2009 and December 2010, ET for SFA atherosclerosis was performed in 54 limbs from 47 patients using a mobile C-arm in the operation theater (mobile group). In contrast, a historical group for comparison consisted of 60 patients, for whom ET for SFA atherosclerosis was performed in 76 limbs using a fixed C-arm in the angiographic suite, between July 2003 and May 2008 (fixed group). The outcomes of ET for both groups were retrospectively analyzed by a medical chart review. RESULTS: There was no statistically significant difference in gender, age, risk factors, Trans-Atlantic Inter-Society Consensus (TASC) classification, intervention type, and postoperative blood creatinine levels between the two groups. However, procedural time was statistically higher in the mobile group. Patency rates at 1 year were 68.3% and 68.1% in the fixed and mobile group, respectively, which was not statistically significant. Subgroup analysis of 1 year patency rates for TASC A, B lesions and TASC C, D lesions were also similar. CONCLUSION: ET using the mobile C-arm in the operating theater is as effective as using the fixed C-arm, in the treatment of SFA atherosclerosis in terms of the technical success, patency, and early postoperative outcomes.

Purpose:
Cryptoglandular fistula is one of the common anal diseases requiring surgical treatment. Various surgical techniques have been introduced; however, there is no known standard technique. Coring-out fistulectomy is a surgical technique that accurately resects only the fistula tract. However, only a few cases of this procedure have been reported.We aimed to analyze the surgical outcomes of coring-out fistulectomy for cryptoglandular anal fistulas.
Methods:
We retrospectively reviewed the medical records of patients who underwent coring-out fistulectomy for a cryptoglandular fistula between 1999 and 2019. Primary outcomes were the treatment success rate (recurrence and healing rates) and incidence of fecal incontinence.
Results:
A total of 184 patients were included in our study. The average age of the patients was 44 years (range, 16–75 years), and 88.0% were male. Twenty-four (13.0%), 13 (7.1%), and 68 patients (37.0%) underwent operation for recurrent fistula, multiple tracts, and complex type fistula, respectively. The healing rate was 92.4%, and recurrence occurred in 15 of 170 healed patients (8.8%). Thus, the treatment success rate was 84.2%. There was no fecal incontinence except in 1 patient who had preoperative fecal incontinence because of cauda equine syndrome. In multivariable analysis of the factors affecting the treatment success rate, the complex fistula (odds ratio [OR], 14.2; 95% confidence interval [CI], 4.7– 43.0; P < 0.001) and undetected internal opening during the operation (OR, 4.0; 95% CI, 1.4–11.6; P = 0.012) were significant factors.
Conclusion
Coring-out fistulectomy is a simple and feasible technique for sphincter-preserving anal fistula surgery.

PURPOSE: Although lymph node (LN) metastasis is an important prognostic marker of colorectal cancer (CRC), the effect of LN metastasis on the survival of stage IV CRC is debated yet. METHODS: LN status and survivals as well as clinicopathological features of synchronous stage IV CRC patients, operated for 8 years, were analyzed. Patients with hematogenous metastases were included only but those with peritoneal seeding or preoperative adjuvant therapy were not included. RESULTS: Total 850 patients were enrolled and 77 (9.1%) were without LN metastases (N0M1). N0M1 patients were older and have favorable pathological features including lower CEA than patients with LN metastasis (N + M1). The pathologically poor features accumulated with N stage progression within N + M1. N0M1 had better 5-year overall survival (OS) and disease free survival than N + M1. And 5-year OS's within N + M1 group were stratified and different according to N stage progression, although the effect of N stage progression is different according to curative resection or not. When compared with stage III, 5-year OS of N0M1 with curative resection was comparable to that of anyTN2aM0 and was better than anyTN2bM1. CONCLUSION: LN metastasis is a significant prognostic factor in stage IV by hematogenous metastasis, too. N stage progression accumulates pathologically poor prognostic factors. However, the effect on survival of each N stage progression differs depending on curative resection or not of the hematogenous metastases.

PURPOSE: The purpose of this study was to determine the potential role of three-dimensional conformal radiotherapy (3D-CRT) in the treatment of primary unresectable hepatocellular carcinoma. The preliminary results on the efficacy and the toxicity of 3D-CRT are reported. MATERIALS AND METHODS: Seventeen patients were enrolled in this study, which was conducted prospectively from January 1995 to June 1997. The exclusion criteria included the presence of extrahepatic metastasis, liver cirrhosis of Child-Pugh classification C, tumors occupying more than two thirds of the entire liver, and a performance status of more than 3 on the ECOG scale. Two patients were treated with radiotherapy only while the remaining 15 were treated with combined transcatheter arterial chemoembolization. Radiotherapy was given to the field including the tumor plus a 1.5 cm margin using a 3D-CRT technique. The radiation dose ranged from 36~60 Gy (median; 59.4 Gy). Tumor response was based on a radiological examination such as the CT scan, MR imaging, and hepatic artery angiography at 4~8 weeks following the completion of treatment. The acute and subacute toxicities were monitored. RESULTS: An objective response was observed in 11 out of 17 patients, giving a response rate of 64.7%. The actuarial survival rate at 2 years was 21.2% from the start of radiotherapy (median survival; 19 months). Six patients developed a distant metastasis consisting of a lung metastasis in 5 patients and bone metastasis in one. The complications related to 3D-CRT were gastro-duodenitis (>or= grade 2) in 2 patients. There were no treatment related deaths and radiation induced hepatitis. CONCLUSION: The preliminary results show that 3D-CRT is a reliable and effective treatment modality for primary unresectable hepatocellular carcinoma compared to other conventional modalities. Further studies to evaluate the definitive role of the 3D-CRT technique in the treatment of primary unresectable hepatocellular carcinoma are needed.

PURPOSE: The authors report a case of bilateral simultaneous central retinal vein occlusion caused by Waldenstrom's macroglobulinemia. CASE SUMMARY: A 65-year-old man presented to our department complaining of decreased visual acuity for the duration of about 6 months. On his initial visit, best-corrected visual acuity was 0.02 in the right eye and 0.06 in the left eye. Based on the findings of a funduscopic examination, the patient had bilateral diffuse retinal hemorrhages, dilated tortuous veins, and macular edema. He had experienced recurrent spontaneous epistaxis 6 months previously and had undergone treatments such as intravitreal bevacizumab injection and intravitreal dexamethasone implantation at another hospital. Laboratory tests at that hospital showed anemia and hyperproteinemia, for which he was referred to our hemato-oncology department. Bone marrow biopsy was consistent with Waldenstrom's macroglobulinemia/lymphoplasmacytoid lymphoma, and he was treated with systemic chemotherapy. One year after the systemic chemotherapy, his best-corrected visual acuity was 0.15 in the right eye and 0.6 in the left eye. Funduscopy showed decreased bilateral retinal hemorrhages and macular edema. CONCLUSIONS: When simultaneous bilateral central retinal vein occlusion occurs in a patient with no other underlying disease such as hypertension or diabetes, it might be a sign of serum hyperviscosity, and there should be a very high level of suspicion for presence or progression of systemic disease. If such a disease is properly and timely diagnosed, effective early systemic evaluation and therapy can be administered, and it is important to have initial general treatment as well as ophthalmic treatment.

PURPOSE: Crohn disease is characterized by high rates of recurrence and reoperations. However, few studies have investigated long-term surgical outcomes in Asian populations. We investigated risk factors for reoperation, particularly those associated with anti-tumor necrosis factor-alpha (anti-TNF-alpha) antibody use, and long-term follow-up results. METHODS: We reviewed the records of 148 patients (100 males and 48 females) who underwent surgery for gastrointestinal Crohn disease and retrospectively analyzed long-term outcomes and risk factors. RESULTS: The mean age at diagnosis was 28.8 years. Thirty-eight patients (25.7%) received monoclonal antibody treatment before reoperation. A small bowel and colon resection was most commonly performed (83 patients, 56.1%). The median follow-up was 149 months, during which 47 patients underwent reoperation. The median interval between the primary and the secondary surgeries was 65 months, with accumulated reoperation rates of 16.5%, 31.8%, and 57.2% after 5, 10, and 15 years, respectively. Obstruction was the most common indication for reoperation (37 patients, 25.0%). In a multivariable analysis, age <17 years at diagnosis (A1) (odds ratio [OR], 2.20; P = 0.023), penetrating behavior (B3) (OR, 4.39; P < 0.001), and no azathioprine use (OR, 2.87; P = 0.003) were associated with reoperation. Anti-TNF-alpha antibody use did not affect the reoperation rate (P = 0.767). CONCLUSION: We showed a high reoperation rate regardless of treatment with anti-TNF-alpha antibody, which indicates that recurrent surgery is still needed to cure patients with gastrointestinal Crohn diseases. Younger age at primary operation, penetrating behavior, and no azathioprine use were significant factors associated with reoperation for gastrointestinal Crohn disease.

PURPOSE: The adverse effects of obesity on short-term surgical outcomes after laparoscopic colorectal surgery have been reported. However, the influence of obesity on long-term oncological outcomes after laparoscopic surgery in Asian patients has not been well understood. The aim of this study was to evaluate the effect of obesity on long-term oncologic outcomes in patients who underwent laparoscopic surgery for colorectal cancer. METHODS: Overall, 424 consecutive patients who underwent laparoscopic resection for colorectal cancer between January 2005 and July 2012 were included in this retrospective study. Patients were classified as non-obese (body mass index [BMI] <25.0 kg/m²) and obese (BMI ≥25.0 kg/m²) according to the categories proposed by the International Obesity Task Force. A survival analysis was performed using clinicopathologic characteristics, including obesity. RESULTS: Of the 424 patients, 325 (76.7%) were classified as non-obese and 99 (23.3%) as obese. The clinicopathologic characteristics of the obese and non-obese groups were similar, except that there were more underlying comorbidities, a lower frequency of smoking, and fewer tumors in rectum in the obese group. Results of the multivariate analysis showed that older age, elevated serum carcinoembryonic antigen, high-grade histology, advanced tumor stage, and perineural invasion were associated with poorer disease-free survival and overall survival. Obesity was not significantly associated with disease-free survival (hazard ratio [HR], 1.196; 95% confidence interval [CI], 0.686~2.086; p=0.528) or overall survival (HR, 1.156; 95% CI, 0.584~2.289; p=0.677). CONCLUSION: Laparoscopic surgery for colorectal cancer seems to be safe and feasible for obese patients in terms of long-term oncologic outcomes.
