PURPOSE: The surgical treatment of anal stenosis includes internal sphincterotomy, rotaton flap and advancement flap according to the stenosis degree, recently, Christensen performed house shaped advancement flap and reported fair results. We compared and analyzed the surgical methods and results in patients with moderate and severe anal stenosis who underwent house shaped advancement flap and C-anoplasty. METHODS: We have performed this study with 6 cases using the house shaped advancement flap and 6 cases using the C-anoplasty. The out come was assessed by clinical characteristics, surgical method, operation time, duration of hospitalization, healing time, postoperative complications, results. RESULTS: The average operation time was 38 min in those house shaped advancement flap cases and 63 min in C-anoplasty cases. The average time of hospitalization was 6 days and 9 days, respectively, and the average time of healing was 28 days and 46 days, respectively. In those house advancement flap cases, surgery could be done in 2 directions at the same time in 4 cases and 3 directions in 2 cases; as for those C-anoplasty cases, surgery could be done in 1 direction in 4 cases and 2 directions in 1 case. Two complications were observed in C-anoplasty, one flap infection and one flap necrosis, and in house shaped advancement flap, no complication was observed. CONCLUSIONS: House shaped advancement flap have several advantages compared to the C-anoplasty, and since house shaped advancement flap could be performed in 2 to 3 directions or even 4 directions at the same time, the anus could sufficiently expanded in severe anal stenosis patients. The house shaped advancement flap might be one of the good method in treating anal stenosis.

PURPOSE: Resection of the bowel or solid organs may be required for pelvic tumor surgery. The present study was performed to assess combined surgical procedures and determine the role of the general surgeon in gynecologic oncology surgery METHODS: We performed a retrospective study of 135 patients with gynecologic malignancy who underwent a combined operation with a general surgeon between January 2000 and December 2005 at Asan Medical Center. The purpose of the combined operation was categorized into 3 groups: a tumor debulking operation, a resolution of intraoperative complications by a gynecologic surgeon, or an intraoperative diagnostic change. RESULTS: The incidence of combined operations for debulking, resolution of intraoperative complications, and intraoperative diagnostic changes were 103 cases (76.3%), 22 cases (16.3%), and 10 cases (7.4%), respectively. Ovarian cancer was the most common gynecologic malignancy (74.1%) and the rate of a combined operation with a general surgeon in ovarian cancer was 18.5% during the time period. Colorectal resection was the most common procedure by a colorectal surgeon (61.5%). Twenty four patients (17.8%) experienced postoperative complications, including ileus, wound infection, pancreas leakage, and stomal necrosis, with no significant differences according to the purpose of combined operation, pathologic diagnosis, or bowel preparation. The rate of a preoperative consultation to a general surgeon by gynecologic surgeons in cases with colorectal or solid organ invasion preoperatively was 53.2%. CONCLUSION: A general surgeon is an important consultant in a debulking operation of gynecologic malignancies, especially ovarian cancer, or treatment of complications. Thorough preoperative evaluation, bowel preparation, and preoperative consultation to a general surgeon is important in gynecologic oncology surgery.

Sleep disturbances are common in patients with stroke, and sleep quality has a critical role in the onset and outcome of stroke. Poor sleep exacerbates neurological injury, impedes nerve regeneration, and elicits serious complications. Thus, exploring a therapy suitable for patients with stroke and sleep disturbances is imperative. As a multi-targeted nonpharmacological intervention, remote ischemic conditioning can reduce the ischemic size of the brain, improve the functional outcome of stroke, and increase sleep duration. Preclinical/clinical evidence showed that this method can inhibit the inflammatory response, mediate the signal transductions of adenosine, activate the efferents of the vagal nerve, and reset the circadian clocks, all of which are involved in sleep regulation. In particular, cytokines tumor necrosis factor α (TNFα) and adenosine are sleep factors, and electrical vagal nerve stimulation can improve insomnia. On the basis of the common mechanisms of remote ischemic conditioning and sleep regulation, a causal relationship was proposed between remote ischemic conditioning and post-stroke sleep quality.

PURPOSE: To describe an unusual case of rapidly progressive outer retinal necrosis (PORN) with vitreous hemorrhage in a 41-year-old woman with acquired immunodeficiency syndrome (AIDS), who had retinitis developed from what was probably varicellar-zoster virus combined with cytomegalovirus (CMV) and herpes simplex type 1,2, as proven by the polymerase chain reaction restriction fragment length polymorphism method (PCR-RFLP). METHODS: This study is a case report detailing clinical follow-up and an aqueous humor test by PCR-RFLP. RESULTS: The deep, white retinal lesions coalesced and progressively expanded in a circumferential manner, with sparing of the perivascular retina. However, retinal and vitreous hemorrhages, unusual findings for PORN, could be noted around the optic nerve. Varicellar-zoster virus (VZV), cytomegalovirus (CMV), and herpes simplex types 1,2 (HSV-1,2) were detected in the aqueous humor by PCR. CONCLUSIONS: PORN has been described as a variant of necrotizing herpetic retinopathy, occurring particularly in patients with AIDS. Although the etiologic agent has been reported to be VZV, concurrent or combined etiologic agents can include HSV-1, HSV-2, and CMV in AIDS patients. Therefore, combined antiviral therapy with acyclovir and ganciclovir could be more reasonable as an initial therapy.

Objective: To explore the clinical characteristics of various types of infected pancreatic necrosis(IPN) and the prognosis of different treatment methods in the imaging classification of IPN proposed. Methods: The clinical data of 126 patients with IPN admitted to the Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from December 2018 to December 2021 were analyzed retrospectively. There were 70 males(55.6%) and 56 females(44.4%), with age(M(IQR)) of 44(17)years (range: 12 to 87 years). There were 67 cases(53.2%) of severe acute pancreatitis and 59 cases (46.8%) of moderately severe acute pancreatitis. All cases were based on the diagnostic criteria of IPN. All cases were divided into Type Ⅰ(central IPN)(n=21), Type Ⅱ(peripheral IPN)(n=23), Type Ⅲ(mixed IPN)(n=74) and Type Ⅳ(isolated IPN)(n=8) according to the different sites of infection and necrosis on CT.According to different treatment strategies,they were divided into Step-up group(n=109) and Step-jump group(n=17). The clinical indicators and prognosis of each group were observed and analyzed by ANOVA,t-test,χ² test or Fisher exact test,respectively. Results: There was no significant difference in mortality, complication rate and complication grade in each type of IPN(all P>0.05). Compared with other types of patients, the length of stay (69(40)days vs. 19(19)days) and hospitalization expenses(323 000(419 000)yuan vs. 60 000(78 000)yuan) were significantly increased in Type Ⅳ IPN(Z=-4.041, -3.972; both P<0.01). The incidence of postoperative residual infection of Type Ⅳ IPN was significantly higher than that of other types (χ²=16.350,P<0.01). There was no significant difference in the mortality of patients with different types of IPN between different treatment groups. The length of stay and hospitalization expenses of patients in the Step-up group were significantly less than those in the Step-jump group(19(20)days vs. 33(35)days, Z=-2.052, P=0.040;59 000(80 000)yuan vs. 122 000(109 000)yuan,Z=-2.317,P=0.020). Among the patients in Type Ⅳ IPN, the hospitalization expenses of Step-up group was significantly higher than that of Step-jump group(330 000(578 000)yuan vs. 141 000 yuan,Z=-2.000,P=0.046). The incidence of postoperative residual infection of Step-up group(17.4%(19/109)) was significantly lower than that of Step-jump group(10/17)(χ²=11.980, P=0.001). Conclusions: Type Ⅳ IPN is more serious than the other three types. It causes longer length of stay and more hospitalization expenses. The step-up approach is safe and effective in the treatment of IPN. However, for infected lesions which are deep in place,difficult to reach by conventional drainage methods, or mainly exhibit "dry necrosis", choosing the step-jump approach is a more positive choice.

A 63-year-old woman was admitted due to right upper quadrant abdominal pain. She was going through hemodialysis due to end stage renal disease and taking calcium polystyrene sulfonate orally and rectally due to hyperkalemia. Colonoscopy showed a circular ulcerative mass on the proximal ascending colon. Biopsy specimen from the mass showed inflammation and necrotic debris. It also revealed basophilic angulated crystals which were adherent to the ulcer bed and normal mucosa. These crystals were morphologically consistent with calcium polystyrene sulfonate. She was diagnosed with calcium polystyrene phosphate induced colonic necrosis and improved with conservative treatment.

Twenty-nine patients haboring primary or recurrent malignant gliomas were treated with direct implantation of radioactive sources into the tumor in afterlozded, removable catheters using stereotatic technique between November 1987 and October 1990. Indine-125(I-125) was implanted in 22 patients and high dose rate(HDR) Iridium-192(Ir-192) in 7 patients. All patients had been treated with external radiation and most had been treated with chemotherapeutic agents. one or more sources were placed in each tumor to deliver 5000-8000 cGy to the tumor's periphery for I-125 and 3000 cGy for HDR Ir-192. Eleven of 13 patients with glioblastoma multiforme were alive at 35 weeks whose mean survival was 74 weeks, and remained two were expired at 35 and 78 weeks, respectively. All 5 patients with anaplastic astrocytoma were alive at 39 weeks whose mean survival was 74 weeks. Five of 9 recurrent blioblastoma were alive at 22 weeks whose mean survival was 44 weeks, and remained three were expired at 13, 17 and 22 weeks respectively. All two patients with anaplastic astrocytoma were alive at 22 and 52 weeks, respectively. Four patients with deep seated analphastic astrocytoma(3 in the thalamus and 1 in the third ventricle) were treated successfully by brachytheray without any surgical morbidity and mortality and they were still alive 38, 48, 74 and 123 weeks after brachytherapy. There were few minor postoperative complications including 3 meningitis. 2 leak of cerebrospinal fluid and 3 radiation necrosis without any mortality. The authors conclude that the brachytherapy with temporary implanted I-125 or Ir-192 sources may provide long-term survial in selected patients with primary or recurrent malignant gliomas.

PURPOSE: Women with large breasts suffer from both physical embarrassment and physical discomfort. Recently, partially due to socioeconomic development, growing numbers of woman with large breasts have sought reduction surgery, which previously had not been popular in Korea. At this time, a proper evaluation of the operation is required in order to promote the procedure. METHODS: Case files of 60 reduction operations using the inferior pedicle flap method for the reduction of large breasts were clinically reviewed. RESULTS: The patients were aged 19~65 (mean 34.5) years. The primary reasons for surgery were self-consciousness, shoulder/neck/back pain, wet skinfold/eczema and intractable mastalgia. Breast parenchymal pattern analysis by mammography revealed relatively a high frequency of dysplastic change (DY) among women with intractable breast pain, which was nearly entirely relieved by reduction surgery. The nipple-areolar complex were saved with inferior dermal pedicle flaps without any occurrence of necrosis. An average of 350 (range 50~800) grams of tissue from each breast was removed. There were no blood transfusions and significant postoperative complications were rare, although some patients complained of hypertrophic scars. CONCLUSION: Postoperative results were sufficiently satifactory to consider reduction surgery for inappropriately large breasts as a rehabilitative method.
