ABSTRACT

El tumor neuroectodérmico maligno del tracto gastrointestinal es una neoplasia rara con pocos casos reportados en la literatura, especialmente en América Latina. Descrito por primera vez en 2003, se trata de una entidad sin tratamiento estandarizado y de pobre pronóstico. Se presenta el caso de una paciente de 22 años de edad que acude a la consulta por dolor abdominal, anemia y masa abdominal palpable. Luego de estudios pertinentes se decide la conducta resectiva y el posterior tratamiento oncológico. (AU)


Malignant gastrointestinal neuroectodermal tumor (GNET), formerly known as clear cell sarcoma of the gastrointestinal tract, is an extremely rare tumor of mesenchymal origin, which presents great microscopic and molecular similarity to clear cell sarcoma found in other parts of the body, such as tendons and aponeurosis. It is characterized by its rapid evolution, high recurrence rate and frequent diagnosis as metastatic disease.1,2 (AU)

ABSTRACT

Treatment of fistula in ano by seton has become less in vogue due to the complications and disadvantages associated with its use. In its place, more technically demanding and expensive procedures, with less morbidity but more recurrence, such as endorectal advancement flaps and laser, are being employed more commonly. To overcome some of the limitations of conventional seton, we have designed a composite seton. In the present study, we evaluated our experience with a composite seton made from two silastic vessel loops sutured together with 5-0 polypropylene. The composite seton was found to not present many of the disadvantages of the conventional seton. The use of the composite seton resulted in low incontinence and recurrence rates, less pain, and high quality of life. This technically simple and cheaper material may have a wider applicability.

ABSTRACT

Las malrotaciones por bandas de Ladd son un subtipo de anormalidades de la embriogénesis consistentes en prolongaciones fibrosas, producto de una fijación anómala del mesenterio. Se extienden desde el ciego mal rotado hacia el retroperitoneo, pudiendo producir compresión extrínseca del duodeno. En el 90% de los casos la presentación clínica tiene lugar dentro del primer año de vida como un cuadro agudo, en forma de oclusión duodenal o vólvulo de intestino delgado con la consecuente isquemia de este o hernia interna. En la edad adulta, las formas de presentación son menos específicas. Los métodos de referencia ("gold standard") utilizados para el diagnóstico son la seriada gastroduodenal y la tomografía computarizada. El tratamiento quirúrgico consiste en la cirugía de Ladd, cuyo abordaje convencional fue descripto en 1936 por William Ladd. Presentamos el caso de un paciente adulto con un cuadro oclusivo, causado por dicha anomalía, diagnosticado de forma oportuna y resuelto de manera segura por vía laparoscópica. (AU)


Ladd's band malrotations are a subtype of abnormalities of embryogenesis consisting of fibrous extensions, product of abnormal fixation of the mesentery, that goes from the poorly rotated cecum towards the retroperitoneum, which can cause extrinsic compression of the duodenum. In 90% of cases, the clinical presentation takes place within the first year of life, as an acute condition, like duodenal occlusion or small bowel volvulus with its consequent ischemia or internal hernia. In adulthood, the forms of presentation are less specific. The gold standard methods used for diagnosis are gastroduodenal series and computed tomography. Surgical treatment consists of Ladd's surgery, whose conventional approach was described in 1936 by William Ladd. We present ta case of an adult patient with an occlusive presentation, given by this anomaly, diagnosed in a timely manner and safely resolved by laparoscopic approach. (AU)

ABSTRACT

Background: Due to few sufficient data regarding the comparison between endoscopic and surgical resection of malignant colorectal polyps regarding outcomes and survival benefits, there are no clear guidelines of management strategies of malignant colorectal polyps. The aims of the present study were to compare endoscopic resection alone and surgical resection in patients with malignant polyps in the colon (T1N0M0) readings advantages, disadvantages, recurrence risks, survival benefits, and long-term prognosis to detect how management strategy affects outcome. Patients and methods: we included 350 patients. All included patients were divided into 2 groups; the first group included 100 patients who underwent only endoscopic polypectomy and the second group included 250 patients who underwent endoscopic polypectomy followed by definitive surgical resection after histopathological diagnosis. We followed all patients for about 5 years, ranging from 18 to 55 months. The primarily evaluated parameters are surgical consequences and patients' morbidity. The secondary evaluated parameters are recurrence risks, recurrence free survival, and overall survival rates. Results: The age of patients who underwent polypectomy is usually younger than the surgical group, males have more liability to polypectomy in comparison with females. Patients with tumors in the left colon have more liability to polypectomy in comparison with the right colon (p< 0.0001). Tumor factors associated with more liability to surgical resection are presence of lymphovascular invasion, high grade, and poor tumor differentiation (p< 0.0001). The management strategy was the most significant predictor of overall and recurrence free survival rates in patients with malignant colon polyps (p< 0.001). Conclusions: We found that survival benefits and lower incidence of recurrence are detected in the surgical resection group more than in the polypectomy group. (AU)

ABSTRACT

Introduction: In current clinical practice, immediate coloanal anastomosis (ICA) remains the standard technique for restoring the gastrointestinal tract following coloproctectomy for low rectal cancer. This anastomosis still requires a temporary diverting stoma to decrease the postoperative morbidity, which remains significantly high. As an alternative, some authors have proposed a two-stage delayed coloanal anastomosis (TS-DCA). This article reports on the surgical technique of TS-DCA. Methods: The case described is of a 53-year-old woman, without any particular history, in whom colonoscopy motivated by rectal bleeding revealed an adenocarcinoma of the low rectum. Magnetic resonance imaging showed a tumor ~ 1 cm above the puborectalis muscle, graded cT3N +. The extension workup was negative. Seven weeks after chemoradiotherapy, a coloproctectomy with total mesorectal excision (TME) was performed. A TS-DCA was chosen to restore the digestive tract. Conclusion: Two-stage delayed coloanal anastomosis is a safe and effective alternative for restoring the digestive tract after proctectomy for low rectal cancer. Recent data seem to show a clear advantage of this technique in terms of morbidity. (AU)

ABSTRACT

Introduction: The second most common cause of cancer-related mortality is colorectal cancer, and laparoscopic-assisted colectomy (LAC) has gained popularity among surgeons as an alternative to the conventional approach, which is open colecrtomy (OC). The differences between LAC and OC in terms of short-term outcomes have not been well documented, and the aim of the present work is to compare the short-term outcomes of both procedures. Materials and Methods: The present prospective study comprised 164 participants submitted to LAC (n = 82) and OC (n = 82) at the Helwan and Zagazig University hospitals between January 2018 and January 2022. We collected and analyzed demographic data, surgical data, and the short-term outcomes. Results: The LAC group had a significantly lower estimated amount of blood loss, shorter hospital stay, lower rates of incisional surgical site infection, and fewer cases of burst abdomen postoperatively, but with a considerably longer operative time (30.3 minutes) than the OC group. Conclusions: Our findings show that LAC is favorable option to OC, with superior outcomes. (AU)

ABSTRACT

ISR is the most widely used anal-preserving operation for ultra-low rectal cancer. It can be divided into total ISR, subtotal ISR and partial ISR according to the resection range of internal sphincter. The advantage of ISR is that it can preserve the sphincter while ensuring the safety of oncology for ultra-low rectal cancer, representing the state of the art. However, it still needs to face the problem that the quality of life will decline due to poor postoperative anal function. The conformal sphincter-preserving operation (CSPO) is a functional anal-preserving surgery improved on the basis of ISR. It is superior to ISR in the postoperative anal function and patients' quality of life. So it can be a new choice for ultra-low rectal cancer.

ABSTRACT

Intersphincteric resection (ISR) is the ultimate sphincter-preserving surgical technique for low rectal cancer. Accurate preoperative diagnosis and staging, appropriate selection of surgical approaches and technique, standardized perioperative management, and postoperative rehabilitation are the keys to ensuring the oncological effect and functional preservation of ISR. To date, there is still a lack of standardized guidance on the clinical implementation of ISR in China. Therefore, based on the latest evidence from literature, expert experience, and the intervention situation in China, the Chinese Society of Colorectal Surgery, Chinese Society of Surgery, Chinese Medical Association organized domestic experts in colorectal surgery to discuss and produce "Chinese expert consensus on intersphincteric resection for low rectal cancer (2023 edition)". This consensus focuses on definition, classification, related pelvic anatomy, operational techniques, postoperative complications, and long-term oncological and functional outcomes, and aims to guide the standardized clinical practice of ISR in the operation of low rectal cancer in China.

ABSTRACT

Conformal sphincter-preservation operation (CSPO) is considered the effective surgical technique for preserving the sphincter in cases of low rectal cancer. Accurate preoperative diagnosis and staging, reasonable selection of surgical approaches and technique, standardized perioperative management, and postoperative rehabilitation are the keys to ensuring the oncological clearance and functional preservation of CSPO. However, there is currently a lack of standardized surgical procedure for implementing CSPO in China. Therefore, the Colorectal Surgery Group of Surgery Branch of the Chinese Medical Association,along with the Colorectal Cancer Committee of the Chinese Medical Doctor Association and the Anorectal Branch of Chinese Medical Doctor Association, gathered experts in colorectal surgery to discuss and establish this standardized surgical procedure of CSPO. This standard, based on the latest evidence from literature, expert experiences, and China national condition, focuses on the definition, classification, pelvic anatomy, surgical techniques, postoperative complications, and perioperative care of CSPO. It aims to guide the standardized clinical practice of CSPO in China.

ABSTRACT

La cirugía del cáncer de recto y ano se ha desarrollado considerablemente en las últimas décadas. En función de dichos avances, se ha observado una disminución en la morbimortalidad operatoria, así como también una mejoría en el pronóstico de estos pacientes. El objetivo del presente estudio es exponer y analizar los resultados del tratamiento quirúrgico del cáncer de recto y ano en un servicio universitario. Se realizó un estudio observacional, descriptivo y retrospectivo de todos los pacientes intervenidos por cáncer de recto y ano en el Hospital Español entre 2016 y 2020. Las variables registradas fueron: variables demográficas, clínico-oncológicas, relacionadas a la morbimortalidad operatoria y a la recidiva locorregional, y la sobrevida a 5 años. El procedimiento más realizado fue la resección anterior de recto (RAR) en 11 intervenciones (58%), mientras que las 8 restantes correspondieron a amputaciones abdominoperineales (AAP) (42%). Se diagnosticaron un total de 6 complicaciones intraoperatorias en 5 pacientes, siendo la perforación del tumor la más frecuente, y un total de 18 complicaciones postoperatorias en 11 pacientes, siendo la más frecuente la infección de la herida quirúrgica abdominal. La morbilidad operatoria mayor fue de 31,6% y la mortalidad operatoria a 90 días fue de 0%. La sobrevida global a 5 años fue de 63,2%. Los resultados quirúrgicos en la presente casuística fueron comparables con los de la bibliografía consultada. Destacamos la nula mortalidad a 90 días, con resultados oncológicos similares a los reportados en la literatura.


Rectal and anus surgery have been developed considerably in the last decades. Based on these advancements, it has been observed a decrease in the surgical morbidity and mortality, as well as an improved prognosis of these patients. The aim of the present study is to expose and analyze the results of the anus and rectal surgical treatment in a university service. An observational, descriptive and retrospective study was performed of all the intervened patients for rectum and anus cancer in the Hospital Español between 2016 and 2020. We recorded data about demographic, clinical-oncologic, related to the surgical morbidity and mortality, locoregional relapse and overall 5 year survival. The most performed procedure was the rectum anterior resection in 11 interventions (58%), while the 8 left corresponded to abdominoperineal resection (42%). There was a total of 6 intraoperative complications diagnosed in 5 patients, being the tumor perforation the most frequent one, and a total of 18 postoperative complications diagnosed in 11 patients, being the surgical wound infection the most frequent one. The serious surgical morbidity was 31,6%, while the surgical mortality rate at 90 days was 0%. Overall 5 year survival was 63,2%. The surgical results in the present study about the rectum and anal cancer were comparable with the results reported on the consulted bibliography. We highlight the null mortality within 90 days, with oncologic results similar to the ones reported in the literature.

ABSTRACT

Background: Despite several improvements in surgical techniques, the intracorporeal division of the distal end of the rectum is still challenging, particularly when it is too deep in a narrow pelvis. Even though it helps avoid spillage, the double-stapling technique (DST) raises concerns regarding safety and anastomotic leakage if multiple stapler firings are essential to complete the rectal division. Objective: To assess the feasibility of vertically dividing the rectum and its impact in reducing the number of reloads essential for that division in non-low rectal cancer patients undergoing total mesorectal excision (TME). Materials and Methods A retroprospective study. Results: From January 2017 to November 2021, a total of 123 patients with sigmoid and rectal cancers were enrolled in the present study; their data were collected and analyzed, and 21 patients were excluded. The remaining sample of 102 subjects was composed of 47 male (46%) and 55 female (54%) patients with a median age of 54 years (range: 30 to 78 years). Only 1 reload was enough to complete the rectal division in 82 (80.39%) cases, and 2 reloads were used in the remaining 20 (19.61%) patients. Anastomotic leakage was clinically evident in 4 cases (3.9%). No statically significant difference was observed when firing one or two staplers. No 30-day mortality was recorded in this series. Conclusion: Our early experience indicates that this type of division has a real advantage in terms of decreasing the number of reloads needed and, in turn, lowering the incidence of anastomotic leakage after partial mesorectal excision (PME) or TME when applied with proper patient selection.

ABSTRACT

Objective: Despite all the technological advances, successful management of complex fistula-in-ano is still a challenge due to recurrence and incontinence. The present study evaluates the outcomes of a novel technique, Interception of Fistula Track with Application of Ksharasutra (IFTAK) in terms of success rate and degree of incontinence. Methods: In the present prospective study, 300 patients with complex fistula-inano were treated by the IFTAK technique, whose surgical steps include: incision at the anterior or posterior midline perianal area, identification and interception of the fistulous track at the level of the external sphincter, rerouting the track (and extensions) at the site of interception, and application of a ksharasutra (medicated seton) in the proximal track (from the site of interception to the internal opening) that is laid open gradually, with the resulting wound healing with minimum scarring. The distal track is allowed to heal spontaneously. Results: There were 227 transsphincteric and 73 intersphincteric varieties of fistula with supralevator extension in 23 cases, of which 130 were recurrent fistulas, 29 had horseshoe track, while 25 had blind fistula with no cutaneous opening. The mean duration of the ksharasutra application was 8.11 ± 3.86 weeks with an overall success rate of 93.33% at the 1-year follow-up. A total of 3.67% of the cases reported with a mild impairment of continence on the Wexner incontinence scoring system. Pre- and postoperative anal manometry evaluation showed minimal reduction in median basal and squeeze pressures. Conclusion: The IFTAK technique is a minimally invasive, daycare surgical procedure for the management of complex fistula-in-ano with low recurrence and minimal sphincter damage. (AU)

ABSTRACT

Objetivo: Evaluar las complicaciones posoperatorias y la evolución clínica en pacientes sometidos a colectomías y anastomosis con dos estrategias preoperatorias, preparación mecánica (PMC) y preparación mecánica con antibióticos orales (PMC+AO). Materiales y Método: Estudio retrospectivo, con un total de 216 pacientes, 149 fueron del grupo PMC y 67 del PMC+AO. Variables estudiadas: características demográficas, intervención quirúrgica, localización anastomótica, fuga anastomótica (FA), infección del sitio operatorio (ISO), tránsito intestinal posoperatorio, infección por Clostridium difficile (CD) y estadía hospitalaria. Para el análisis estadístico se realizaron modelos bivariados y multivariados. Resultados: La FA fue más frecuente en el grupo PMC (7,38% vs. 0%, p = 0,011). En colectomías del lado izquierdo, la diferencia más marcada en las FA de ambos grupos fue en anastomosis del recto medio, sin casos en el grupo PMC+AO (0% vs. 50%, p = 0,019). En colectomías derechas, la FA fue similar para ambos grupos. Hubo más ISO en el grupo PMC (4,7% vs. 0%, p = 0,037). La recuperación del tránsito intestinal fue más rápida para el grupo PMC+AO, determinando menor estadía hospitalaria (3,98 días vs. 6,39 días, p = 0,001). El grupo PMC+AO se asoció a mayor tasa de colitis por CD (4,48% vs. 0,67%, p = 0,008). Discusión y Conclusión: El uso de la preparación intestinal con antibióticos orales podría ayudar a prevenir la FA en las colectomías izquierdas y evitar las ISO, favoreciendo la recuperación del tránsito intestinal, reduciendo la estadía hospitalaria. La asociación a CD debe examinarse en estudios más amplios.


Aim: To evaluate postoperative complications and clinical evolution in patients undergoing colectomies and anastomosis with two preoperative strategies, mechanical bowel preparation alone (MBP) and mechanical bowel preparation with oral antibiotics (MBP+OA). Materials and Method: Retrospective study, with defined inclusion and exclusion criteria. Variables studied: preoperative demographic characteristics, surgical intervention, anastomotic location, anastomotic leakage (AL), surgical site infection (SSI), postoperative intestinal transit, Clostridium difficile (CD) infection and hospital stay. Statistical analysis, bivariate and multivariate models were performed. Results: 216 patients studied, 149 were MBP group and 67 MBP+OA group. The group MBP had higher rates of AL (7.38% vs. 0%, p = 0.011). For left-sided colectomies, AL rate in both groups had a higher difference in the middle rectum, with no cases in the MBP+OA group (0% vs. 50%, p = 0.019). For right colectomies, the AL rates were similar in both groups. SSI was higher in MBP group (4.7% vs. 0%, p = 0.037). The bowel transit recovery was faster for MBP+OA group, determining less hospital stay (3.98 days vs. 6.39 days, p = 0.001). The group MBP+OA had a higher rate of CD colitis, 4.48% (p = 0.008). Discussion and Conclusion: These results suggest that preoperative oral antibiotic with mechanical bowel preparation could help to prevent anastomotic leaks in left-sided colectomies, also avoid surgical site infection, favoring the recovery of postoperative bowel transit, reducing hospital stay. The association to CD should be examined in larger studies.

ABSTRACT

Background: There are many surgical approaches which described extent of resection of the colon for adequate surgicalmanagement of splenic flexure cancer, but up till now there is no established surgical procedure, this is because the presence of double lymphatic drainage of themesenteric vessels. Segmental resection of the colon for the management of splenic flexure cancer was a recently accepted surgical procedure. Objective: In the present study, we aimed to compare three surgical management techniques to clarify the best management approach of Egyptian patients with splenic flexure cancer regarding operative, clinical, and oncological outcomes: segmental resection, and extended left or right hemicolectomy,. Materials and Methods In the present study, we included 90 patients with splenic flexure cancer. Cases were divided into 3 groups. Each group included 30 patients in order to compare three surgical techniques: segmental resection, extended left hemicolectomy, and extended right hemicolectomy. Results: We have found no statistically significant differences between the three included groups regarding operative findings, postoperative complications, local recurrence, distant recurrence, disease progression, recurrence-free survival rate, progression-free survival rate, and overall survival rate. The operative time was longer, and the number of lymph nodes was higher in the extended right hemicolectomy group (p<0.001). Conclusion: We have shown that segmental resection of the splenic flexure is surgically and clinically suitable for the adequate management of operable cases of carcinoma of the splenic flexure.

ABSTRACT

Intersphincteric resection (ISR), as an ultra-low sphincter-preserving operation, is widely used in clinical practice at present. ISR can allow some patients with very low rectal cancer to avoid the pain of anal resection while ensuring oncological efficacy. However, the procedure of ISR requires wider intersphincteric dissection which may cause nerve damage, and the removal of partial or total internal anal sphincter as an "inherent defect" of ISR can result in poor anal function postoperatively. Based on the in-depth understanding of regional anatomy and physiological function, the author proposed a new functional sphincter preservation operation for very low rectal cancer-conformal sphincter preservation operation (CSPO) which has achieved good outcome in clinical practice. This article will revisit the brief history of rectal cancer surgery and discuss the main mechanisms underlining the poor anal function after ISR. Based on the anatomical study of the pelvic floor and anal canal, CSPO can improve the postoperative anal function of very low rectal cancer patients by reducing the damage of the autonomic nerves, receptor corpuscles and muscle fibers in the intersphincteric space, retaining more dentate line and internal sphincter with the design of resection line of tumor lower border under direct vision, and elevating the anastomosis height. At the same time, the future treatment prospect of low rectal cancer is envisioned.

ABSTRACT

Resumen Las fístulas anorrectales complejas son un desafío para el coloproctólogo. Son una patología frecuente que afecta la calidad de vida de los pacientes. La patogénesis aún no está clara, estarían involucradas citoquinas y el proceso de transición de epitelio a mesénquima. El gold standard para su estudio es la resonancia nuclear magnética, su uso por sí mismo disminuye la recurrencia. El objetivo del tratamiento es lograr la curación sin afectar la función del esfínter evitando las recidivas. Existen múltiples técnicas, siendo la de mayor aceptación la ligadura interesfinteriana del trayecto fistuloso, con tasa de curación sobre el 70%, con mínimo impacto en continencia.
