Aim: To characterize the preferences and frequency of surgical techniques for the resolution of pilonidal disease (PSD) in colorectal surgeons of Latin America. Materials and Method: Cross-sectional descriptive and analytical study using an electronic survey validated by expert peers. Distributed among colorectal surgeons in Latin America. Surgeons who were not subspecialists in colorectal surgery were excluded. Results: 372 responses were obtained from subspecialist surgeons in colorectal surgery from 15 Latin American countries, with a mean of 18.9 ± 12.5 years as subspecialists. 66.7% use open techniques for chronic PSD, the most used techniques: marsupialization (31.5%), unroofing (27.7%) and resection with the Karydakis technique (17.7%), Limberg flap (6, 1%), Bascom (5.4%), Z or VY plasties (4%), McFee (3.8%) and Epsit (3.8%). The most used intervention for the resolution of acute PSD is drainage under formal anesthesia with curettage and/or marsupialization (51.1%). 45.3% of surgeons change techniques during their career. Discussion: Due to the wide distribution and representativeness of the respondents, it was possible to capture the preference in a realistic way about the management of the PSD by the subspecialists of the continent, contributing with information with which there is no precedent. Conclusion: Open techniques are preferred for the resolution of chronic PSD, marsupialization, unroofing and Karydakis were used the most. The change of surgical technique within subspecialists is frequent, there is a relationship between preferring open techniques to the extent that surgeons have more years of experience.

Introducción: Quistes hepáticos son formaciones de contenido líquido-seroso rodeado de parénquima hepático normal y sin comunicación con la vía biliar intrahepática. Mayor incidencia en adultos mayores de 50 años, con una relación mujer / hombre de 1.5: 1. Son asintomáticos. Los síntomas se presentan debido a su tamaño o bien por la presencia de complicaciones como la hemorragia, la rotura, la infección intraquística, o la compresión de estructuras adyacentes. Objetivo: Caracterizar a una paciente que presenta quiste hepático gigante complicado por rotura traumática. Caso clínico: Paciente femenino de 81 años, acudió a emergencia luego de haber presentado caída impactándose sobre superficie dura a nivel de parrilla costal e hipocondrio derecho, presentó dolor abdominal intenso acompañado de nausea y vómito. Al examen físico mostró signos claros de irritación peritoneal. Se realizó tomografía axial computarizada que reporta rotura de la pared de quiste hepático y aproximadamente 600 ml de líquido libre en cavidad. Se efectúo tratamiento quirúrgico de emergencia al realizar destechamiento del quiste y lavado de la cavidad. Conclusiones: Los quistes hepáticos, debido a su tamaño o complicaciones pueden poner en peligro la vida de los pacientes. Es necesario que dentro del arsenal diagnóstico del cirujano esté presente el conocimiento de esta patología(AU)

Introduction: Hepatic cysts are formations with liquid-serous content surrounded by normal liver parenchyma and without communication with the intrahepatic bile duct. It is reported with higher incidence in adults over fifty years of age, with a women/men ratio of 1.5: 1. They are asymptomatic; symptoms appear due to either their size or the presence of complications such as hemorrhage, rupture, intracystic infection, or compression of adjacent structures. Objective: To characterize a patient with a giant hepatic cyst complicated by traumatic rupture. Clinical case: A 81-year-old female patient went to the emergency room after falling and subsequently impacting herself on a hard surface at the level of the rib cage and right hypochondrium; she presented intense abdominal pain accompanied by nausea and vomiting. The physical examination showed clear signs of peritoneal irritation. A computerized axial tomography was performed, reporting rupture of the hepatic cyst wall and approximately 600 mL of free fluid within the cavity. Emergency surgical treatment was performed after cyst unroofing and cavity washing. Conclusions: Hepatic cysts, due to their size or complications, can endanger the patients' lives. It is necessary for the surgeon to consider knowledge of this condition as part of his or her diagnostic resources(AU)

A Surgical Experience of Unroofing for Anomalous Aortic Origin of Right Coronary Artery with Ischemia in Adult / 日本心臓血管外科学会雑誌

We describe a 50-year-old man who was diagnosed with anomalous aortic origin of the right coronary artery (AAORCA) by coronary angiography and coronary computed tomography performed for chest pain on exertion. Exercise-loaded myocardial scintigraphy revealed inferior wall ischemia, and hence surgery was performed. Intraoperatively, the right coronary artery was seen to run in the aortic wall, and hence, right coronary ostioplasty (unroofing) was performed. Postoperatively, coronary computed tomography revealed that the right coronary artery originated from a normal position, and exercise-loaded myocardial scintigraphy indicated no ischemia.

Clinical outcomes of transperitoneal laparoscopic unroofing and fenestration under seminal vesiculoscopy for seminal vesicle cysts / 亚洲男科学杂志(英文版)

Symptomatic seminal vesicle cysts (SVCs), especially those of a large size, can be removed by surgical treatments. Currently, open surgeries for SVC are rarely performed due to their extensive surgical trauma, and minimally invasive surgical therapies for treating seminal vesicle cysts are still in the early stages. In addition, relevant studies are mostly confined to case reports. In this study, we retrospectively reviewed 53 patients who had received transperitoneal laparoscopic unroofing or fenestration under seminal vesiculoscopy for SVC in our institution. Both surgeries decreased the cyst volume to a significant extent; however, according to the remnant lesion size after rechecking images, seminal vesiculoscopic fenestration tended to have a higher recurrence than laparoscopic unroofing. Regarding complications, two individuals in the laparoscopic unroofing group experienced ureteral injury and rectal injury, while patients in the fenestration group only had temporary hemospermia, which indicates that fenestration surgery tends to have less severe complications than laparoscopic unroofing. There was no solid evidence confirming semen improvement after these surgical therapies in our study. Future studies with a prospective design, larger sample size, and longer follow-up period are required to verify and further explore our findings.

A Case of Rectal Mucosa-associated Lymphoid Tissue Lymphoma Diagnosed by Endoscopic Unroofing Technique / 대한소화기학회지

Mucosa-associated lymphoid tissue (MALT) lymphoma is a typical primary gastrointestinal lymphoma, particularly in the stomach. Although primary rectal lymphoma is rare, it may present as a subepithelial tumor. Several techniques have been proposed for a tissue diagnosis in subepithelial tumor, including endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA), EUS-guided trucut biopsy (EUS-TCB), and tacked biopsy. However the diagnostic efficacy of these techniques appears to be limited. The unroofing technique involves removal of the overlying mucosa, thereby exposing the subepithelial lesion. It was originally reported as a method for endoscopic treatment of colorectal lymphangioma. In this case, a subepithelial tumor of the rectum was diagnosed using the endoscopic unroofing technique. This is a useful modality for the diagnosis of subepithelial tumor, because it provides histologic results in a safe and rapid manner.

Managements of simple liver cysts: ablation therapy versus cyst unroofing

BACKGROUNDS/AIMS: Simple liver cysts were easily recognizable with the advanced imaging procedures, such as ultrasound and computed tomography scan. A large cyst or significant symptoms were indications for the treatments. Ablation therapy with sclerotic agents was effective, but there were several complications including severe pain. With the surgical cyst unroofing method introduced, we compared the cyst unroofing method and ablation therapy. METHODS: Between March 1997 and May 2011, we performed treatments of simple liver cysts in 27 patients. There were 23 women and 4 men (age range: 42-84 years; mean age: 64 years). The cyst unroofing was undergone with laparoscopic (n=13) and open technique (n=1). The ablation therapy was performed with ethanol (n=13) and acetic acid (n=1). RESULTS: The usual symptoms of the liver cysts were abdominal mass (n=7), indigestion (n=4), abdominal discomfort (n=3), and the increasing size of the cysts (n=4). The mean diameter of the cysts was 10.9 cm. The cyst unroofing method was performed effectively in 14 patients. One patient had bleeding during operation, and was converted to the open technique. One patient had a bile leak from the cyst, but it was successfully closed with the laparoscopic technique. Among the 14 cases with the ablation therapy, there were 4 complications: hematoma (n=1); cyst leaking during aspiration (n=2); acute renal failure (n=1); and death due to acetic acid intoxication (n=1). CONCLUSIONS: Laparoscopic cyst unroofing was more effective and safer in management than the ablation therapy in simple liver cysts.

Enfermedad de hígado poliquístico asociado con quiste esplénico / Polycystic liver disease associated with splenic cyst

La enfermedad poliquística del hígado en el adulto es una condición infrecuente y benigna, autosómica dominante, asociada con frecuencia a enfermedad poliquística renal. Se caracteriza por la formación de quistes hepáticos numerosos, con o sin afectación renal. Algunos otros factores probablemente implicados en su génesis son la edad, sexo femenino, embarazo, y el uso de anticonceptivos orales. Las terapias quirúrgicas incluyen la aspiración percutánea del quiste con el escleroterapia, fenestración laparoscópica, fenestración laparotómica, la resección del hígado y el trasplante del hígado. Caso: Hombre de 50 años de edad con diagnóstico de hígado poliquístico asociado a un quiste esplénico diagnosticado por TAC abdominal y que se trató con una técnica de videoloparoscopia. Conclusión: La intervención quirúrgica para la enfermedad del hígado poliquístico sintomático se ha asociado a una morbilidad significativa. La fenestración videolaparoscópica de los quistes es un método seguro y extremadamente efectivo y se debe considerar como tratamiento inicial para la enfermedad del hígado poliquístico.

Polycystic liver in the adult is a rare and benign, autosomal dominant disorder, frequently associated with renal polycystic disease. It is distinguished by formation of numerous hepatic cysts, with or without renal involvement. Some other factors are also thought to be involved in its genesis, such as age, female gender, pregnancy, and the use of oral birth control pills. Surgical therapies include percutaneous cyst aspiration with sclerotherapy, laparoscopic fenestration, open fenestration, liver resection and fenestration and liver transplantation. Case: Polycystic liver disease associated with splenic cyst was diagnosed in a 50 years old man by abdominal computed tomography imaging and videolaparoscopic finding. Conclusion: Surgical intervention for symptomatic polycystic liver disease has been associated with significant morbidity. Laparoscopic cysts fenestration was safe and extremely effective and should be considered as initial treatment for polycystic liver disease.

A Case of Giant Colonic Lipoma Endoscopically Removed Using an Unroofing Technique in Phases / 대한소화기내시경학회지

Gastrointestinal lipomas are benign adipose tumors that are usually submucosal, and most commonly found in the colon. However, they have also been discovered in the small bowel, stomach and very rarely in the esophagus. Although most of gastrointestinal lipomas are asymptomatic and are found incidentally at time of endoscopy, surgery or autopsy, large lipomas can cause acute abdominal pain, bowel habit changes, gastrointestinal bleeding, intussusception or bowel obstruction. Lipomas can be diagnosed by colonoscopy, abdominal CT, barium series and endoscopic ultrasonography (EUS). Large lipomas need to be treated using various techniques. However, the best treatment modality for large lipomas has not yet been established. A surgical resection of lipomas should be considered for a giant lipoma >2 cm in diameter due to the risk of perforation or hemorrhage. Currently, endoscopic snare polypectomy or endo-loop ligation is used to treat symptomatic lipomas, which may reduce the risk of complications associated with endoscopic treatment. We report a case of giant colonic lipoma that was diagnosed successfully with EUS and treated safely using an endoscopic unroofing technique, endoloop ligation and snare polypectomy in phases.

A Case of Endoscopic Unroofing after Detachable Snare Ligation of a Duodenal Duplication Cyst / 대한소화기내시경학회지

A duodenal duplication cyst is rare congenital anomaly, which accounts for 5% of all gastrointestinal duplication cysts. Most of the duodenal duplication cysts are usually found during infancy or early childhood, and present with obstructive symptoms. The most common clinical manifestations are an intestinal obstruction or, less commonly, hemorrhage, perforation, biliary obstruction or pancreatitis. The traditional treatment of a duodenal duplication cyst has been complete surgical resection, but very few cases of endoscopic treatment of a duodenal duplication cyst have been previously reported recently in the literature. Moreover, endoscopic treatment of a duodenal duplication cyst has not been reported in Korea. We report our first experience of a duodenal duplication cyst, including diagnosis and endoscopic management with a detachable snare.

Laparoscopic cyst unroofing in the treatment of ploycystic kidney: A report of 13 cases / 中国微创外科杂志

Objective To explore the operative approach, method,indication,and clinical feasibility of laparoscopic or retroperitoneoscopic treatment of ploycystic kidney.Methods The renal cyst unroofing(bilateral,9 cases;unilateral,4 cases) was performed under laparoscope(2 cases) or retroperitoneoscope(11 cases).The renal adipose capsule was dissected with a harmonic scalpel to fully visualize the whole kidney.According to preoperative positioning results,the cysts at all sizes were exposed.Then all visible cysts were unroofed or fenestrated with a margin 0.5 cm from the renal parenchyma.The cystic fluid was drawn out as much as possible.Results The operations were completed smoothly in the 13 cases.Pneumatothorax developed on the day of laparoscopic operation in 1 case,and then was cured by closed thoracic drainage.The operation time was 50～240 min(mean,139 min),and the blood loss was 10～200 ml(mean,58 ml).Patients began out-of-bed activities in 1～2 days after operation and were discharged from hospital at 3～10 days.The pathological findings were in accordance with changes of ploycystic kidney.Follow-up examinations were carried out for 1～30 months(mean,14.3 months).Back pain was relived in 8 out of 11 cases.In 3 patients with a high blood pressure,the systolic pressure was decreased by 16～19 mm Hg at 9 months after operation.Ten patients presented normal hepatic and renal functions,while the remaining 3 patients with preoperative increased creatinine levels of 194～301 ?mol/L had a drop by 20～40 ?mol/L.Conclusions Treatment of cyst unroofing under laparoscope or retroperitoneoscope is a safe and effective method in the treatment of ploycystic kidney,being worthy of clinical recommendation.

Retroperitoneal laparoscopic operations in the treatment of renal cyst: Report of 35 cases / 中国微创外科杂志

Objective To explore the techniques and efficacy of retroperitoneal laparoscopic operations in the treatment of renal cyst. Methods A total of 35 patients were operated on under general anesthesia. A water-filled balloon was used to dilate the retroperitoneal cavity. The renal cyst was exposed by identifying the psoas major muscle, peritoneal reflection, pillar of diaphragm and so on. All cyst walls were unroofed with ultrasonic scalpel 3～5 mm from the edge of renal parenchyma. Results With renal cysts removed, the operations were successfully accomplished in all the 35 patients. The operation time was 15～60 min (mean, 32 min). The intraoperative blood loss was 5～60 ml (mean, 35 ml). The postoperative hospital stay was 3～6 days. Pathological examinations reported benign lesions in 34 patients and suspected cystadenocarcinoma in 1 patient. All the 35 patients were followed for 1～22 months. No recurrence was found with exception of 1 case of remaining renal cyst 1.5 cm in diameter under B-ultrasonography at the first postoperative month. The patient with suspected adenocarcinoma had been followed for 1 year and no evidences of neoplasm or metastasis were detected on the chest roentgenogram and B-ultrasonography of the liver and the kidneys. Conclusions Retroperitoneal laparoscopic unroofing is a safe and effective procedure for renal cyst.

Endoscopic Unroofing Therapy for Colonic Lymphangioma: A report of two cases / 대한소화기내시경학회지

A lymphangionma is a rare benign tumor occuring in the gastrointestinal tract, which is composed of lymphatic vessels of various size. A sharply demarcated smooth, soft, cystic submucosal tumor which is easily compressible and covered with normal mucosa is a characteristic ally an endoscopic feature. This lesion is considered to be a benign lesion, which does not need to be treated, but in cases that involve risk of any complications or symptoms, the lesion needs to be removed. Servral endoscopic treatment methods for a symptomatic lymphangioma have been introduced, but accompanying risk of complications, such as bleeding or perforation were reported. As complete removal of a lymphangioma is impossible due to its broad base, a newly developed unroofing method is presented to be effective and safe for resection of a large lymphan-gioma. Recently, 2 cases were experienced involving a lymphangioma in the large intestine, which was removed successfully by colonscopic unroofing therapy.

Treatment of the Hemospermia / 대한비뇨기과학회지

To evaluate the etiology and treatment of options in patients with hemospermia, we retrospectively reviewed 21 patients who had both transrectal ultrasound and MRI and have been followed for more than 6 months after initiation of treatment. Mean age was 40 years (range 20 - 50 years) with duration of infliction being 24 months (range 1 week to 16 years). Among the 14 patients with prostatic cyst, 9 patients underwent transurethral unroofing (TUUR) of cyst. All 9 patients were completely cured, but one patient developed postoperative epididymitis. Among the 6 patients with prostatitis, hemospermia was resolved in 4 patients after mean treatment of 12 weeks with antibiotics. In DES (Diethylstilbestrol) group, 50 % showed resolution of symptoms among 6 patients after 4 weeks of treatment, and two patients complained breast discomfort which were developed after medication. In conclusion, the antibiotic treatment is advisable in hemospermia patients with prostatitis. Prostatic cystic lesion is believed to be a factor in hemospermia, thus TUUR of cyst wall and removal of stone and hematoma in cyst can be a viable option.
