They are usually small in size, but sometimes they become enlarged, causing unexpected medical conditions. An extremely rare case of a giant hypertrophied anal papilla complicated by obstructive ileus is reported. Fibroepithelial anal polyp, despite its size, should be included in the differential diagnosis of a smooth mass located near the anal verge, especially in a patient with a history of chronic anal irritation or infection.展开更多

A comparison is made with a group of parents following routine hospital. A secondary aim was to illuminate the parents’ feelings and concerns in the first month after the birth of the child. Subjects and methods: The program was tested in 20 Vietnamese mothers of babies born with an imperforate anus;10 followed an intervention comprising an education program and 10 the ordinary routine hospital. The study design is both qualitative and quantitative. The mothers were interviewed, using open-ended questions, within a week of their child’s birth and then repeatedly for up to one month. Finally, the conditions of children were accessed on their return to the hospital for the second operation after one month of care at home. The qualitative data were subjected to content analysis. Results: All mothers felt sad and worried in the beginning, but this quickly changed to confidence, particularly among mothers in the intervention group who received education. While at home, mothers in both groups had financial concerns, as they were unable to work as much as expected and also had to buy equipment for colostomy care. The mothers in the control group complained about a lack of knowledge and how it affected the care of their child. The mothers in the intervention group, however, felt confident in their caring even at home. When the families returned for the second operation, the children in the intervention group were significantly healthier, had increased more in weight, and had fewer complications and emergency return visits to hospital compared to the control group. In the control group skin problems around the stoma, diarrhea, bleeding or constipation while at home were reported (p < 0.01). Conclusion: The education improved the care at home resulting in healthier children and more confident parents.展开更多

Therapeuticeffects of the treatment on postoperative severe pain, retention of urine, constipation, and bleedingwere observed clinically. Results indicated that the cure rate was 97. 6 % and the total effective ratewas 100%. Strong stimulation of Chengshan(BL 57) point improved mainly postoperative edema,spasm, local edema. The improvement of hyperemia and spasm is a ma jor factor of curing various postoperative complication of the anus and intestine. The therapeutic method has advantages of using lesspoints, rapidly producing effects, shorter therapeutic course, suffering little for patients, and no sideeffect.展开更多

She was born with an imperforate anus and a recto-vaginal fistula; she underwent repair at 6 mo of age. At 29 years of age, she was still fecally incontinent despite extensive pelvic floor reeducation. A magnetic resonance imaging and an anal electromyography were performed. Because her symptoms were considered to be probably due to extra-sphincteric implantation of the neo-anus, a redo was performed of the recto-neo-anal intra-sphincteric anastomosis. A neurostimulator device was subsequently implanted for persistent incontinence. Solid and liquid FI resolved, and her quality of life improved markedly. Combining surgery to correct the position of the neo-anus within the anal sphincter complex and neurostimulation could thus become a new approach in cases of refractory FI for patients with imperforate anus as a newborn. Follow-up into adulthood after pediatric imperforate anus surgery should be recommended for adult patients with persistent FI.展开更多

This would facilitate the adoption of anus saving operation.Before and after fully isolation of the rectum in low ratal cancer surgery, the distance between the lower tumor margin and the anorectal line was measured by the same rectuscope introduced through the anus.The two results were compared .The average lengthening was less than 1 cm if the lower tumor marginanorectal line distance was 5 cm.It was 1─2 cm if the lower tumor margin-anorectal distance was 6 cm.It was more than 2 cm if the distance was 7─9 cm.The loosening and lengthening of the rectal canal was related to the presence of lymphnode metastasis and the skill of the operator.The lengthening was also influenced by the body build of the patient,involvement of the rectal circumference and the Dukes stage. Modified Park's operation,trans abdominosacral resection with anastormosis of rectum,and anterior resection on transpubic approach are indicated for those in whom the lower tumor margin-anorectal line distance was 5 cm The rectectomy-anastomosis in the abdominal cavity(Dixon's operation)is indicated for those in whom the lower tumor margin-anorectal line was 6 cm.If manual anastomosis is difficult,stapling device may be used. The anus saving resection is easy if the distance was 7─9 cm.展开更多

The measurements were compared. By the same method,the distance between the lower tumor margin and the intended resectyion line was measured immediately before resection.It was compared with the measurement immediately after the resection.In 83 rectal cancer specimens, the extent of intramural infiltration toward the anus was:≤0.5 cm in 75 cases (90.4%).≥l cm in 2 cases which showed highly malignant carcinomas.These 2 cases, however,should not have been indicated for anus-saving resection.In 46 fresh specimens,the tumor-resection line distances gave an average of 2.7 cm.After fixing in 10% formalin, they became shortened by 0.7 cm. And, mouting in sections further shortened them by another 0.5 cm,giving a total shortening of l.2 cm.The tumor-resection line distance in 7 of the 11 fresh specimens resected by the Dixon's operation was shortened,though never more than o.5 cm immediately the operation.In performin ganus-saving resection for the low rectal cancer, after full isolation the rectum and stretching it slightly,≥3 cm of the rectum distal to the lower tumor margin should be resected.A safety margin of more than 2.5 cm is necessary in the fresh specimen.If formalin fixed specimen is measured, the safety margin should be ≥2 cm.展开更多

Local recurrence was correlated with improper safety margin from the lower edge of cancer to the anal end. There was statistical significant difference between 3 cm or more and 2 cm or less. The local recurrence was also related to the pathologic stage, histologic differentiation and implant of free cancer cells. It is suggested that the surgical indication of saving the anus be strict and without stretching, the safety margin from the lower edge of cancer to the anal end should not be less than 2 cm in early rectal cancer and not less than 4 cm in advanced lesions. During the operation, no touching tumor technique, thorough rinsing of the peritoneal cavity and pre- or post-operative radiotherapy are important for prevention of local recurrence. Early local recurrent rectal cancer can be detected by periodic examinations.展开更多

The Content: The content of this research paper includes a description of the patient, an analysis of the clinical picture, diagnostic methods and therapeutic interventions used, a report of the following disease, and the result of the presented case. The Result of the Research Work: The result of the research work is the analysis of a clinical case with two different tumors, where such a combination of tumors is rarely described in the literature. Moreover, no large specific sample with this combination of diseases is available. Patient Characteristics: The given case report describes a patient of the Palliative Care Unit of the Gerontology Clinic with a primary diagnosis of C20-rectal adenocarcinoma in the background of the anal canal, perineal skin Paget’s disease, stage IV. The presented complications of the patient’s primary diagnosis are multiple metastases in the liver;status post palliative chemotherapy;hepatomegaly;metastases to abdominal lymph nodes, inguinal lymph nodes;metastases at Th12, L4 level;pain syndrome. The presented above combination of diagnosed diseases is very rare. Applied Diagnostics: In October 2021, it was performed diagnostic manipulation: biopsy and the pathologist have provided a microscopic description. The first tissue fragment had a pronounced electrothermal lesion and the epithelial structures were not valuable. The second skin tissue fragment was covered with hyperplastic and acanthotic epithelium;its basal and middle layers contained multiple large cells proliferates extending into the medial epidermis, and the cytoplasm of these cells reacted positively with PAS (Periodic Acid Schiff reaction). It needs to be noted that the patient had previously had several years of biopsies from the perineal and anal epidermis, where Paget’s disease had also been diagnosed. The performed immunohistochemistry showed these cells to be CK20 positive, CK7 rare positive and p16 negative. The following pathohistological findings were made: morphological and immunohistochemical picture is consistent with Paget’s disease. According to the ICD-10, the patient was diagnosed with C51 malignant neoplasm of the female external genitalia. Using imaging diagnostics, it became clear that the patient’s rectal adenocarcinoma had progressed to metastatic stage with distant liver metastases in the background of anal canal, perineal skin Paget’s disease. Therapeutic Plan of the Patient: Based on the patient’s main diagnoses, the complications of the principal diagnosis, the patient’s overall severe condition, pain syndrome, age and comorbidities, palliative chemotherapy was approved as a therapeutic option in council of doctors. Monitoring and Outcome of the Patient: The patient’s general condition was becoming worse over time, and she was diagnosed with exitus latalis in December 2022. At that time, the patient was discharged from hospital and was on palliative care at home under the control of her family physician.展开更多

The aim of this study is to discuss the results of crystallized phenol application that we performed for patients with sinus pilonidalis located near anus with 95% success rate. Patients and Methods: Patients admitted between 2005 to 2011 with sinuses located in 2 cm range of anus or were primarily located up to 2 cm to the anal verge were enrolled in the study. Patients’ demographic features, Body Mass Index (BMI), family history, skin color, hair thickness, number of sinus openings, and the status of the sinus (acute vs. chronic) were recorded. Crystallized phenol was applied into the sinus. The pa tients were followed-up after recovery during the first 6 months and annually afterwards. Results: A total of 25 sinus pilonidalis cases located near anus were encountered. All patients were male;crystallized phenol application was per formed on all patients a total of 115 times. The mean number of applications was 5.6 (between 4 and 8 times). The mean recovery period was 74.5 days (range: 31 - 154) and the mean follow-up period was 36.16 months (range: 18 - 48). No surgical intervention was required. Conclusion: Sinus pilonidalis cases located in perianal region can be successfully treated with the crystallized phenol application which is a simple and inexpensive method, that can easily be performed in an outpatient setting.展开更多
