Long-term Evaluation of Fistulotomy and Immediate Sphincteroplasty as a Treatment for Complex Anal Fistula.

BACKGROUND: Fistulotomy with immediate sphincteroplasty is a technique that can heal fistulas and decrease fecal incontinence more effectively than fistulotomy alone, in selected patients. OBJECTIVE: We aimed to perform a long-term evaluation of fecal incontinence after fistulotomy and immediate sphincteroplasty in patients with complex anal fistula. DESIGN: This prospective study included patients undergoing fistulotomy and immediate sphincteroplasty for complex anal fistula from January 2000 to December 2010. SETTINGS: The study was conducted by 2 colorectal surgeons in the coloproctology unit of the General Hospital of Elche. PATIENTS: We included patients aged ≥18 years with complex anal fistulas of cryptoglandular origin. MAIN OUTCOME MEASURES: Main outcomes were recurrence and continence after fistulotomy and immediate sphincteroplasty, according to fistula tract height and preoperative continence status. RESULTS: A total of 107 patients were included; 68.2% were men, with a mean age of 48 years and mean fistula duration of 12.8 months. The range and median follow-up period were 84 to 204 and 96 months. Thirty-seven fistulas were not primary. The overall healing rate was 84.1%. Primary fistulas healed by the end of follow-up in 58 (82.9%) of 70 patients; recurrent fistulas healed in 32 (86.5%) of 37; high tracts healed in 31 (83.8%) of 37, and nonhigh fistulas healed in 59 (84.3%) of 70. Male sex (OR = 0.66 (95% CI, 0.20-2.13); p > 0.05) and recurrent fistulas (OR = 0.43 (95% CI, 0.11-1.68); p > 0.05) could have a protective effect against postoperative fecal incontinence; however, more studies with larger sample sizes are necessary to confirm this result, whereas high fistulas showed a 4-fold increased risk of incontinence (range, 1.22-13.06; p < 0.01). One in 5 high-tracts patients experienced continence deterioration. LIMITATIONS: This was a prospective study, and randomized clinical trials with more patients and longer follow-up are needed to compare fistulotomy and immediate sphincteroplasty with other sphincter-preserving techniques. CONCLUSIONS: Fistulotomy and immediate sphincteroplasty are good options for treating complex anal fistulas, especially for recurrent fistulas, men, and patients with nonhigh tracts, with acceptable recurrence and incontinence rates.

EVALUACIN A LARGO PLAZO DE LA FISTULOTOMA Y LA ESFINTEROPLASTIA INMEDIATA COMO TRATAMIENTO PARA LA FSTULA ANAL COMPLEJA: ANTECEDENTES:La fistulotomía y la esfinteroplastia inmediata es una técnica que puede curar las fístulas y disminuir la incontinencia fecal de manera más efectiva que la fistulotomía sola, en pacientes seleccionados.OBJETIVO:Nuestro objetivo fue realizar una evaluación a largo plazo de la incontinencia fecal después de la fistulotomía y la esfinteroplastia inmediata en pacientes con fístula anal compleja.DISEÑO:Este estudio prospectivo incluyó pacientes sometidos a fistulotomía y esfinteroplastia inmediata por fístula anal compleja, desde enero de 2000 hasta diciembre de 2010.ENTORNO CLINICO:El estudio fue realizado por dos cirujanos colorrectales de la Unidad de Coloproctología del Hospital General de Elche.PACIENTES:Se incluyeron pacientes ≥ 18 años con fístulas anales complejas de origen criptoglandular.PRINCIPALES MEDIDAS DE VALORACION:Los principales resultados fueron la recurrencia y la continencia después de la fistulotomía y la esfinteroplastia inmediata, de acuerdo con la altura del trayecto de la fístula y el estado de continencia preoperatoria.RESULTADOS:Se incluyeron un total de 107 pacientes; El 68,2% eran varones, con una edad media de 48 años y una duración media de la fístula de 12,8 meses. El rango y la mediana del período de seguimiento fue de 84-204 y 96 meses, respectivamente. Treinta y siete fístulas no fueron primarias. La tasa de curación general fue del 84,1%. Las fístulas primarias cicatrizaron al final del seguimiento en 58/70 (82,9%) pacientes; las fístulas recurrentes cicatrizaron en 32/37 (86,5%); los tractos altos cicatrizaron en 31/37 (83,8%) y las fístulas no altas cicatrizaron en 59/70 (84,3%). El sexo masculino (razón de posibilidades: 0,66 [0,20-2,13], p > 0,05) y las fístulas recurrentes (razón de posibilidades: 0,43 [0,11-1,68], p > 0,05) podrían tener un efecto protector contra la incontinencia fecal postoperatoria, sin embargo, más estudios con una muestra más grande son necesarios para confirmar este resultado. Fistulas altas mostraron un riesgo cuatro veces mayor de incontinencia ([1.22-13.06], p < 0.01). Uno de cada cinco pacientes con tractos altos experimentó un deterioro de la continencia.LIMITACIONES:Este fue un estudio prospectivo y se necesitan ensayos clínicos aleatorios con más pacientes y un seguimiento más prolongado para comparar la fistulotomía y la esfinteroplastia inmediata con otras técnicas de preservación del esfínter.CONCLUSIÓN:La fistulotomía y la esfinteroplastia inmediata son buenas opciones para el tratamiento de fístulas anales complejas, especialmente para fístulas recurrentes, varones y pacientes con tractos no altos, con tasas aceptables de recurrencia e incontinencia.

[Laparoscopic treatment of sigmoid colon intussusception secondary to giant submucosal lipoma]. / Tratamiento laparoscópico de invaginación en sigma por lipoma submucoso gigante.

Colonic lipomas have very low frequency, are usually asymptomatic and diagnosis is made incidentally. Seventy-five per cent of lipomas larger than 4 cm are symptomatic, causing abdominal pain, rectal bleeding, obstruction and exceptionally invagination. The resection of invaginated segment is mandatory in cases with invagination and can be performed by laparoscopy when colonic dilation is moderate. We present a 73-year-old man who entered the emergency department complaining of intermitent abdominal pain, rectal bleeding, absence of bowel movements and flatulence, during four days. A CT scan showed a generalized colonic dilation until left lower quadrant. A colo-colonic invagination secondary to an endoluminal lipoma was observed in sigmoid colon. A laparoscopic sigmoidectomy was performed with extracorporeal termino-terminal anastomosis. The postoperative period was uneventful and the patient was discharged from the hospital five days later. A sumbmucous colonic lipoma was diagnosed in the pathological study.

Modulating nitric oxide release by S-nitrosothiol photocleavage: mechanism and substituent effects.

The photochemistry and photophysics of a series of S-nitrosothiols (RSNOs) have been studied computationally. The photocleavage mechanism of the model compound CH(3)SNO to release CH(3)S· and ·NO was studied at the CASPT2 level resulting in a barrierless process when irradiating in the visible region (S(1)), in the near UV region (S(2)) and for photosensitized (T(1)) reaction. The absorption energy required to initiate photocleavage was calculated at the CASPT2 and B3P86 levels showing the possibility of the modulation of NO release by RSNO photoactivation as a function of the substituent R. Good correlations between the wavelengths of the lowest energy (1)(n,π*) and (1)(π,π*) transitions of aryl S-nitrosothiols and the corresponding Hammett constants of the substituents have been obtained.

Effect of peritoneal lavage with clindamycin-gentamicin solution on infections after elective colorectal cancer surgery.

BACKGROUND: Colorectal surgery may lead to infections because despite meticulous aseptic measures, extravasation of microorganisms from the colon lumen is unavoidable. STUDY DESIGN: A prospective, randomized study was performed between January 2010 and December 2010. Patient inclusion criteria were a diagnosis of colorectal neoplasms and plans to undergo an elective curative operation. Patients were divided into 2 groups: Group 1 (intra-abdominal irrigation with normal saline) and Group 2 (intraperitoneal irrigation with a solution of 240 mg gentamicin and 600 mg clindamycin). The occurrence of wound infections and intra-abdominal abscesses were investigated. After the anastomosis, a microbiologic sample of the peritoneal surface was obtained (sample 1). A second sample was collected after irrigation with normal saline (sample 2). Finally, the peritoneal cavity was irrigated with a gentamicin-clindamycin solution and a third sample was obtained (sample 3). RESULTS: There were 103 patients analyzed: 51 in Group 1 and 52 in Group 2. There were no significant differences between the groups in age, sex, comorbidities, or type of colorectal surgery performed. Wound infection rates were 14% in Group 1 and 4% in Group 2 (p = 0.009; odds ratio [OR] 4.94; 95% CI 1.27 to 19.19). Intra-abdominal abscess rates were 6% in Group 1 and 0% in Group 2 (p = 0.014; OR 2.14; 95% CI 1.13 to 3.57). The culture of sample 1 was positive in 68% of the cases, sample 2 was positive in 59%, and sample 3 in 4%. CONCLUSIONS: Antibiotic lavage of the peritoneum is associated with a lower incidence of intra-abdominal abscesses and wound infections.

Structural Substituent Effect in the Excitation Energy of a Chromophore: Quantitative Determination and Application to S-Nitrosothiols.

A methodology for the prediction of excitation energies for substituted chromophores on the basis of ground state structures has been developed. The formalism introduces the concept of "structural substituent excitation energy effect" for the rational prediction and quantification of the substituent effect in the excitation energy of a chromophore to an excited electronic state. This effect quantifies exclusively the excitation energy variation due to the structural changes of the chromophore induced by the substituent. Therefore, excitation bathochromic and hypsochromic shifts of substituted chromophores can be predicted on the basis of known ground and excited potential energy surfaces of a reference unsubstituted chromophore, together with the ground state minimum energy structure of the substituted chromophore. This formalism can be applied if the chemical substitution does not affect the nature of the electronic excitation, where the substituent effect can be understood as a force acting on the chromophore and provoking a structural change on it. The developed formalism provides a useful tool for quantitative and qualitative determination of the excitation energy of substituted chromophores and also for the analysis and determination of the structural changes affecting this energy. The proposed methodology has been applied to the prediction of the excitation energy to the first bright state of several S-nitrosothiols using the potential energy surfaces of methyl-S-nitrosothiol as a reference unsubstituted chromophore.

¿Están los servicios de cirugía general y del aparato digestivo preparados para ofrecer docencia de calidad acorde con los nuevos planes de formación? / Are the general and digestive surgery services prepared to offer a quality training according to the new teaching plans?

Introducción En los últimos meses se ha asistido a una actualización del programa formativo de los residentes y a una regulación de los aspectos importantes de su formación. Un elemento fundamental del proceso de formación son las unidades docentes, a las que se debe exigir que cumplan con los requisitos indispensables adaptados a los nuevos tiempos, como garantía de calidad. Objetivo Identificar los aspectos mejorables en la formación y conocer con qué recursos parten las unidades docentes para afrontar el cumplimiento del nuevo programa de formación. Material y método El estudio se ha realizado en todas las unidades docentes acreditadas para la formación de residentes en la Comunidad Valenciana mediante formularios enviados tanto a los tutores como a los residentes y reuniones mantenidas con los residentes. Resultados La tasa de participación fue elevada (el 100% de tutores y el 92% de residentes). Se han detectado deficiencias en los requisitos de las unidades docentes y en la calidad de la formación percibida por los residentes, sobre todo en los campos de la investigación y en la actividad docente. Se constatan importantes diferencias entre hospitales. Conclusiones Se debe incidir en el cumplimiento de todos los requisitos necesarios para la acreditación de las unidades docentes y hacer hincapié en la actividad docente e investigadora. La implementación de los nuevos planes de formación requiere de una supervisión que corrija las diferencias encontradas entre los distintos servicios (AU)

Introduction In recent months we have witnessed an update of the residents training program and the regulation of important training aspects. Teaching units are an important aspect of the training process, which should be required to comply with the prerequisites adapted to changing times as a guarantee of quality. Aim To identify areas for improvement in training, and the baseline resources of the units to deal with the implementation of the new training program. Material and methods The study was carried out in all units with accredited educational programs in the Valencian Community with questionnaires answered by tutors and residents, and meetings held with them. Results T he participation rate was high (100% of tutors and 92% of residents). Some deficiencies in the requirements of the surgical units and in the quality of the training felt by the residents are detected, mainly in the research and educational activity fields. Huge differences between hospitals are found. Conclusions More attention must be paid to fulfilling all the requirements needed for the accreditation of the teaching units, with an emphasis on educational and research activities. The implementation of the new training program requires monitoring to minimise the differences found between the units (AU)

[Mechanical bowel preparation. A necessity or nothing more (or less) than the weight of tradition?]. / Preparar el colon para la cirugía. Necesidad real o nada más (y nada menos) que el peso de la tradición?

Mechanical bowel preparation is a traditional procedure for preparing patients for colorectal surgery. This practice aims to reduce the risk of postoperative infectious complications since colonic fecal content has classically been related to stool spillage during surgery and anastomotic disruption. However, increasing evidence against its routine use can be found in experimental studies, clinical observations, prospective studies, and meta-analyses. We performed a review of the literature on mechanical bowel preparation and its consequences. There is no clear evidence that preoperative bowel cleansing reduces the septic complications of surgery and routine use of this procedure may increase anastomotic leaks and morbidity. Therefore, the results suggest that mechanical preparation is not required in elective colon and rectal surgery and that its use should be restricted to specific indications such as small nonpalpable tumors to aid their localization during laparoscopic procedures or to enable intraoperative colonoscopy. The role of mechanical bowel preparation in rectal surgery is not well defined and further trials with a larger number of patients are required.

Preparar el colon para la cirugía. ¿Necesidad real o nada más (y nada menos) que el peso de la tradición? / Mechanical bowel preparation. A necessity or nothing more (or less) than the weight of tradition?

La preparación mecánica del colon es un componente tradicional del preoperatorio de los pacientes sometidos a cirugía colorrectal dirigido a reducir sus complicaciones infecciosas, ya que clásicamente la presencia de heces en el colon se ha asociado a contaminación intraoperatoria y dehiscencias anastomóticas. Sin embargo, en la actualidad, estudios tanto experimentales como de observaciones clínicas, trabajos prospectivos y revisiones sistemáticas de la literatura cuestionan su utilidad. Se efectúa una revisión de conjunto sobre el tema, y se concluye que, con la evidencia disponible, no está claro el beneficio de la preparación mecánica del colon y hay trabajos que muestran incluso una mayor incidencia de complicaciones en la tasa de dehiscencia anastomótica y la morbilidad con su uso sistemático, por lo que puede ser omitida en cirugía electiva y es adecuado restringirla a indicaciones concretas, como pequeños tumores, para facilitar su localización durante un abordaje laparoscópico o cuando se precise hacer una endoscopia intraoperatoria. El papel de la preparación mecánica en la cirugía rectal no está aclarado en la actualidad y se precisa de series más amplias para establecerlo (AU)
