BACKGROUND Rectocutaneous fistulae are common.The infection originates within the anal glands and subsequently extends into adjacent regions,ultimately resulting in fistula development.Cellular angiofibroma(CAF),also known as an angiomy ofibroblastoma-like tumor,is a rare benign soft tissue neoplasm predominantly observed in the scrotum,perineum,and inguinal area in males and in the vulva in females.We describe the first documented case CAF that developed within a rectocutaneous fistula and manifested as a perineal mass.CASE SUMMARY In the outpatient setting,a 52-year-old male patient presented with a 2-year history of a growing perineal mass,accompanied by throbbing pain and minor scrotal abrasion.Physical examination revealed a soft,well-defined,non-tender mass at the left buttock that extended towards the perineum,without a visible opening.The initial assessment identified a soft tissue tumor,and the laboratory data were within normal ranges.Abdominal and pelvic computed tomography(CT)revealed swelling of the abscess cavity that was linked to a rectal cutaneous fistula,with a track-like lesion measuring 6 cm×0.7 cm in the left perineal region and attached to the left rectum.Rectoscope examination found no significant inner orifices.A left medial gluteal incision revealed a thick-walled mass,which was excised along with the extending tract,and curettage was performed.Histopathological examination confirmed CAF diagnosis.The patient achieved total resolution during follow-up assessments and did not require additional hospitalization.CONCLUSION CT imaging supports perineal lesion diagnosis and management.Perineal angiofibromas,even with a cutaneous fistula,can be excised transperineally. 展开更多

BACKGROUND Benign rectal strictures can be categorized as primary(disease-related)and secondary(surgical anastomosis-related).Secondary strictures arise from surgical complications,whereas primary strictures have diverse etiologies,including various inflammatory conditions.Benign strictures are usually managed by surgery and endoscopy.We present an unusual etiology of benign rectal stricture caused by the repeated insertion of foreign objects into the rectum for sexual purposes,resulting in rectal injury and subsequent chronic inflammation.CASE SUMMARY A 53-year-old man presented to the outpatient clinic of the Colorectal Surgery Department with symptoms of chronic constipation and bloody stools.The patient previously experienced rectal injury due to foreign object insertion for sexual purposes.Colonoscopy revealed benign circumferential narrowing of the rectum.He underwent treatment by endoscopic argon plasma coagulation and balloon dilation and follow-up as an outpatient for 4 months.A colonoscopy at the end of the follow-up period revealed no evidence of rectal stricture relapse.CONCLUSION A history of rectal injury,followed by chronic inflammation,should be considered in patients with benign rectal strictures.Management with endoscopic argon plasma coagulation and balloon dilation can prevent the need for surgical resection of benign rectal strictures. 展开更多

BACKGROUND Ileostomies are commonly performed after colon and rectal surgeries.Laparoscopy-assisted ileostomy with adhesion lysis may have potential benefits over conventional open surgery.AIM To compare the outcomes of laparoscopy-assisted and conventional ileostomies.METHODS Data from 48 consecutive patients who underwent ileostomy at our institution between May 2021 and May 2022 were retrospectively analyzed.The groups comprised 26 and 22 patients who underwent laparoscopic ileostomy(laparoscopic group)and conventional ileostomy(conventional group),respectively,performed by a single surgeon.Patient demographics,operative characteristics,postoperative outcomes,and 30-d morbidities and mortality rates were analyzed.RESULTS The two groups had comparable mean ages,sex distributions,American Society of Anesthesiologists scores,and body mass indices.However,the laparoscopic group showed similar operative time,better visualization for adhesion lysis,and lower visual analog scale scores than the conventional group.CONCLUSION Laparoscopy-assisted ileostomy is a safe and efficient method that produces lower visual analog scale scores,better intraoperative visualization for effective adhesion lysis,and similar operative time compared with conventional ileostomy. 展开更多

BACKGROUND Slow transit constipation(STC)has traditionally been considered as a functional disorder.However,evidence is accumulating that suggests that most of the motility alterations in STC might be of a neuropathic etiology.If the patient does not meet the diagnosis of pelvic outlet obstruction and poorly response to conservative treatment,surgical intervention with subtotal colectomy may be effective.The most unwanted complication of the procedure is anastomotic leakage,however,preservation of the superior rectal artery(SRA)may reduce its incidence.AIM To evaluate the preservation of the SRA in laparoscopically assisted subtotal colectomy with ileorectal anastomosis in STC patients.METHODS This was a single-center retrospective observational study.STC was diagnosed after a series of examinations which included a colonic transit test,anal manometry,a balloon expulsion test,and a barium enema.Eligible patients underwent laparoscopically assisted total colectomy with ileorectal anastomosis and were examined between January 2016 and January 2018.The operation time,blood loss,time to first flatus,length of hospital days,and incidence of minor or major complications were recorded.RESULTS A total of 32 patients(mean age,42.6 years)who had received laparoscopic assisted subtotal colectomy with ileorectal artery anastomosis and preservation of the SRA.All patients were diagnosed with STC after a series of examinations.The mean operative time was 151 min and the mean blood loss was 119 mL.The mean day of first time to flatus was 3.0 d,and the mean hospital stay was 10.6 d.There were no any patients conversions to laparotomy.Post-operative minor complications including 1 wound infection and 1 case of ileus.There was no surgical mortality.No anastomosis leakage was noted in any of the patients.CONCLUSION Laparoscopically assisted subtotal colectomy with ileorectal anastomosis and preservation of the SRA can significantly improve bowel function with careful patient selection.Sparing the SRA may protect against anastomosis leakage. 展开更多

BACKGROUND Anal stenosis is a rare but frustrating condition that usually occurs as a complication of hemorrhoidectomy.The severity of anal stenosis can be classified into three categories:mild,moderate,and severe.There are two main surgical treatments for this condition:scar revision surgery and anoplasty;however,no studies have compared these two approaches,and it remains unclear which is preferrable for stenoses of different severities.AIM To compare the outcomes of scar revision surgery and double diamond-shaped flap anoplasty.METHODS Patients with mild,moderate,or severe anal stenosis following hemorrhoidectomy procedures who were treated with either scar revision surgery or double diamond-shaped flap anoplasty at our institution between January 2010 and December 2015 were investigated and compared.The severity of stenosis was determined via anal examination performed digitally or using a Hill-Ferguson retractor.The explored patient characteristics included age,sex,preoperative severity of anal stenosis,preoperative symptoms,and preoperative adjuvant therapy;moreover,their postoperative quality of life was measured using a 10-point scale.Patients underwent proctologic follow-up examinations one,two,and four weeks after surgery.RESULTS We analyzed 60 consecutive patients,including 36 men(60%)and 24 women(40%).The mean operative time for scar revision surgery was significantly shorter than that for double diamondshaped flap anoplasty(10.14±2.31[range:7-15]min vs 21.62±4.68[range:15-31]min;P<0.001).The average of length of hospital stay was also significantly shorter after scar revision surgery than after anoplasty(2.1±0.3 vs 2.9±0.4 d;P<0.001).Postoperative satisfaction was categorized into four groups:45 patients(75%)reported excellent satisfaction(scores of 8-10),13(21.7%)reported good satisfaction(scores of 6-7),two(3.3%)had no change in satisfaction(scores of 3-5),and none(0%)had scores indicating poor satisfaction(1-2).As such,most patients were satisfied with their quality of life after surgery other than the two who noticed no difference due owing to the fact that they experienced recurrences.CONCLUSION Scar revision surgery may be preferable for mild anal stenosis upon conservative treatment failure.Anoplasty is unavoidable for moderate or severe stenosis,where cicatrized tissue is extensive. 展开更多

BACKGROUND Thymic carcinoma is a rare,aggressive tumor arising from the thymus.In less than 7%of patients with thymic carcinoma,extrathoracic metastases occur in the extrathoracic lymph nodes,liver,and bone.Isolated splenic metastasis can occur but is very uncommon.To date,only 2 cases of splenic metastases from thymic carcinoma have been reported.CASE SUMMARY A 45-year-old man presented with chronic cough,dyspnea,persistent hoarseness and unintentional weight loss 17 kgs in 6 mo.Neck magnetic resonance imaging revealed a large,lobulated,soft-tissue mass measuring 5.4 cm×6.6 cm×3.8 cm which involved the left superior mediastinum and supraclavicular fossa.Chest computed tomography(CT)revealed a confluent and lobulated soft tissue mass encased the right brachiocephalic artery,right and left carotid arteries,and left subclavian artery in the mediastinum.A fluorodeoxyglucose-positron emission tomography was arranged for malignancy survey.The image revealed intense fluorodeoxyglucose avidity in a soft tissue lobulated mass occupying the superior mediastinum,over the cystic lesion in the spleen and in few enlarged nodules over the left supraclavicular fossa.CT-guided biopsy of the thymic mass and the ultrasound-guided biopsy of the splenic lesion were consistent with a thymic carcinoma with splenic metastasis.The patient was diagnosed of thymic carcinoma,cT2N2M1b,stage IVb.CONCLUSION A fluorodeoxyglucose(FDG)-positron emission tomography(PET)scan can provide a useful diagnostic value in conjunction with pathological result in evaluating tumor staging.Our case emphasizes the utility of FDG-PET for metastasis detection in thymic carcinoma. 展开更多

Diaphragmatic hemangiomas are extremely rare. Only nine cases have been reported in English literature to date. We report a case of cavernous hemangioma arising from the diaphragm. Pre-operative three-dimensional(3D)simulation and minimal invasive thoracoscopic excision were performed successfully, and we describe the radiologic findings and the surgical procedure in the following article.CASE SUMMARY A 40-year-old man was referred for further examination of a mass over the right basal lung without specific symptoms. Contrast-enhanced computed tomography revealed a poorly-enhanced lesion in the right basal lung, abutting to the diaphragm, measuring 3.1 cm × 1.5 cm in size. The mediastinum showed a clear appearance without evidence of abnormal mass or lymphadenopathy. A preoperative 3D image was reconstructed, which revealed a diaphragmatic lesion. Video-assisted thoracic surgery was performed, and a red papillary tumor was found, originating from the right diaphragm. The tumor was resected, and the pathological diagnosis was cavernous hemangioma.CONCLUSION In this rare case of diaphragmatic hemangioma, 3D image simulation was helpful for the preoperative evaluation and surgical decision making. 展开更多
