Impact of Preoperative Three-Dimensional Endoanal Ultrasound on the Surgical Outcome of Primary Fistula in Ano. A Multi-Center Observational Study of 253 Patients.

PURPOSE: To evaluate the impact of preoperative three-dimensional endoanal ultrasound (3D-EAUS) on the clinical outcome of anal fistula surgery. METHODS: The research consisted of multi-center retrospective case-control study including 253 consecutive adult patients undergoing surgery for confirmed or suspected primary fistula in ano who had undergone preoperative 3D-EAUS evaluation between January 2011 and January 2021. Main outcome measures were the concordance (K value) between ultrasound results and surgery in the identification of fistulas internal openings, primary tracts and secondary extensions and the 6 and 12 months success rate in patients with concordant and discordant findings. RESULTS: A good agreement in the identification of the main fistulas characteristics between ultrasound results and operative findings was found. A significant difference (P < .0001; Fisher's exact test) in the success rate was found between patients with concordant and discordant ultrasound results and operative findings in identification or location of internal opening. Particularly, all the 11 (4.8%) patients with discordant results experimented a failure of the surgical procedure at 6 months follow-up. At re-operation, the shift from discordant to concordant results was associated with an 81.8% 12 months success-rate. CONCLUSION: The three-dimensional endoanal ultrasound preoperative evaluation may have a relevant impact on the outcome of a defined group of patients undergoing surgery for anal fistula, since the careful evaluation of ultrasound results could simplify the internal orifice intra-operative detection and improve the success rate.

The Relevance of the Excessive Perineal Descent in the Obstructed Defecation Syndrome: A Prospective Study of 141 Patients.

BACKGROUND: Despite the widely accepted association between excessive straining and perineal descent, the clinical significance of perineal descent in patients with obstructed defecation syndrome is still unclear. OBJECTIVE: This study aimed to evaluate the prevalence of pathological perineal descent in patients with obstructed defecation syndrome and the impact of perineal descent on symptoms severity. DESIGN: This was a prospective multicenter uncontrolled study. SETTINGS: The study involved 3 hospital pelvic-care centers and was conducted from January 2018 to January 2022. PATIENTS: The study included 141 consecutive adult patients with an obstructed defecation syndrome score of 9 or more and no evidence of organic GI pathology. All the patients underwent dynamic pelvic MRI and, in case of suspected paradoxical puborectalis contraction, anal manometry. MAIN OUTCOME MEASURES: Main outcome measures were the prevalence of excessive perineal descent and the correlation between perineal descent and obstructed defecation syndrome score. RESULTS: One hundred twenty-eight patients (90.7%) completed magnetic resonance examination and were included in the analysis. Of these, 18 patients (14.1%) had a physiological perineal descent and 110 (85.9%) had an excessive perineal descent. Excessive perineal descent was found in 46.1% of patients (12/26) with MRI signs of paradoxical puborectalis contraction and in 96% of patients (98/102) with normal puborectalis relaxation. In this latter group of patients, a good correlation between obstructed defecation syndrome score and maximum perineal descent during straining was found (Spearman r test: 0.68; p < 0.0001). LIMITATIONS: The study was limited by the small sample size and by the strong selection of the study population. CONCLUSIONS: Excessive perineal descent is a common finding in patients with obstructed defecation syndrome and high symptoms score, occurring almost consistently in patients without paradoxical puborectalis contraction. In these patients, the maximum perineal descent seems to be well correlated with symptoms severity. See Video Abstract at http://links.lww.com/DCR/C135 . LA RELEVANCIA DEL DESCENSO PERINEAL EXCESIVO EN EL SNDROME DE DEFECACIN OBSTRUIDA UN ESTUDIO PROSPECTIVO DE PACIENTES: ANTECEDENTES:A pesar de la asociación ampliamente aceptada entre el esfuerzo excesivo y el descenso perineal, la importancia clínica del descenso perineal en pacientes con síndrome de defecación obstruida aún no está clara.OBJETIVO:Evaluar la prevalencia del descenso perineal patológico en pacientes con síndrome de defecación obstruida y el impacto del descenso perineal en la severidad de los síntomas.DISEÑO:Este fue un estudio prospectivo multicéntrico no controladoENTORNO CLINICO:El estudio involucró a tres centros hospitalarios de atención pélvica y se llevó a cabo entre enero de 2018 y enero de 2022.PACIENTES:El estudio incluyó a 141 pacientes adultos consecutivos con puntuación del síndrome de defecación obstruida ≥ 9 y sin evidencia de patología gastrointestinal orgánica. A todas las pacientes se les realizó resonancia magnética pélvica dinámica y, en caso de sospecha de contracción puborrectal paradójica, manometría anal.PRINCIPALES MEDIDAS DE RESULTADO:Las principales medidas de resultado fueron la prevalencia del descenso perineal excesivo y la correlación entre el descenso perineal y la puntuación del síndrome de defecación obstruida.RESULTADOS:Ciento veintiocho (90,7%) pacientes completaron el examen de resonancia magnética y fueron incluidos en el análisis. De estos, 18 (14,1%) presentaron descenso perineal fisiológico y 110 (85,9%) descenso perineal excesivo. Se encontró descenso perineal excesivo en el 46,1% (12/26) de los pacientes con signos de contracción puborrectal paradójica en la resonancia magnética y en el 96% (98/102) de los pacientes con relajación puborrectal normal. En estos últimos pacientes se encontró una buena correlación entre la puntuación del síndrome de defecación obstruida y el descenso perineal máximo durante el esfuerzo (prueba r de Spearman: 0,68; p < 0,0001).LIMITACIONES:El estudio estuvo limitado por el pequeño tamaño de la muestra y por la fuerte selección de la población de estudio.CONCLUSIONES:El descenso perineal excesivo es un hallazgo común en pacientes con síndrome de defecación obstruida y alto puntaje de síntomas, ocurriendo casi constantemente en pacientes sin contracción puborrectal paradójica. En estos últimos pacientes el descenso perineal máximo parece estar bien correlacionado con la severidad de los síntomas. Consulte Video Resumen en http://links.lww.com/DCRC135 .

Inferior Mesenteric Artery Ligation Level in Rectal Cancer Surgery beyond Conventions: A Review.

Within the intricate field of rectal cancer surgery, the contentious debate over the optimal level of ligation of the inferior mesenteric artery (IMA) persists as an ongoing discussion, influencing surgical approaches and patient outcomes. This narrative review incorporates historical perspectives, technical considerations, and functional as well as oncological outcomes, addressing key questions related to anastomotic leakage risks, genitourinary function, and oncological concerns, providing a more critical understanding of the well-known inconclusive evidence. Beyond the dichotomy of high versus low tie, it navigates the complexities of colorectal cancer surgery with a fresh perspective, posing a transformative question: "Is low tie ligation truly reproducible?" Considering a multidimensional approach that enhances patient outcomes by integrating the surgeon, patient, technique, and technology, instead of a rigid and categorical statement, we argued that a balanced response to this challenging question may require compromise.

Safety and effectiveness of minimal sphincterotomy in the treatment of female patients with chronic anal fissure.

To evaluate the outcome of a left lateral internal sphincterotomy extended for 20% of total sphincter length in female patients with chronic anal fissure, high anal resting pressure and normal preoperative anal continence. Between January 2014 and January 2018 all the female patients with chronic anal fissure showing failure of medical therapy, perfect anal continence (Cleveland Clinic Florida incontinence score = 0) and high anal resting pressure underwent a lateral internal sphincterotomy extended for 1/5 of total lateral sphincter length, basing on the preoperative measurements by three-dimensional endoanal ultrasound. Postoperative follow-up included clinical assessment at 3, 6 and 12 months associated with manometric and ultrasonographic evaluation at 6 months. Thirty-two patients, [median age 45 (range 19-68)] were included and, of these, 2 (6.2%) were lost to follow-up. At 6 month follow-up success rate was 93.3% (28/30) and continence score was 0 in all the patients. Two patients (6.2%) with poor outcome showed incomplete sphincterotomy at EAUS and underwent re-surgery. At three-dimensional endoanal ultrasound the median length of sphincterotomy was 6 mm (5-8.2). At 12 month follow-up the success rate was 100% and Cleveland Clinic Florida incontinence score remained 0 in all the cases. Open left lateral internal sphincterotomy extended for about 20% of total left lateral internal sphincter length seems to be safe and effective in the treatment of chronic anal fissure in suitable female patients achieving a high success rate without compromising anal continence.

Unusual bleeding of a giant cell fibroblastoma: a soft tissue sarcoma of the skin mimicking metastatic melanoma.

A 56 year-old man presented to the emergency department after a spontaneous bleeding of a giant mass located on the right axilla. Clinical diagnosis was recurrent hemorrhagic nodular melanoma. Ten months previously a malignant melanoma had been removed from the dorsum by radical excision and surgical margins had been disease-free (MM: Breslow IV, Clark IV, lung and lynphnode metastases). The patient required immediate emergency surgical intervention to prevent death by hemorrhagic shock. The tumor was bleeding and the patient required a transfusion. Subjective symptoms included pain in palpation and spontaneous hemorrhage, poor general appearance, pale skin, BP 80/40 mmHg, HR 100/min with overall symptoms of hypovolemic shock. At the time of surgery, radical tumor excision was performed with an approximately 3 cm circumferential gross tumor free margin. The resultant defect was reconstructed by pectoral rotation fascio-cutaneous flap. The histological diagnosis demonstrated an undifferentiated high-grade pleomorphic sarcoma with microscopic tumor free margins.

Antibiotic prophylaxis and risk of infections in thyroid surgery: results from a national study (UEC-Italian Endocrine Surgery Units Association).

Thyroid surgery is considered a clean procedure, and therefore antibiotic prophylaxis is not recommended. However, antibiotic prophylaxis is often used in clinical practice. Aim of the present study is to show the rate of infections in thyroid surgery and whether antibiotic prophylaxis, among other factors, is associated with a lower infection rate in 2,926 patients (constituting the cohort of UEC-Italian Endocrine Surgery Units Association) who had a thyroid surgical operation between the years 2009 and 2011. Antibiotic prophylaxis was used in 1,132 interventions (38.7 %). We recorded 28 cases of infections (rate = 1 %). At univariate analysis the lack of drainage and of antibiotic prophylaxis were factors associated with infection development. However, we noticed a concentration of cases of infections (10 of the 28 total cases) in one single center that showed a very high rate of infection (8.8 %). At logistic regression analysis the only independent predictor of infection development was belonging to that center, while the lack of antibiotic prophylaxis was not. In conclusion, our study shows that infection rate in thyroid surgery was 1 %. The use of an antibiotic prophylaxis was not associated with a protection from these infections.
