ABSTRACT

El schwannoma es una patología rara del nervio facial. Su diagnóstico preoperatorio es dificultoso dado que no tiene síntomas ni signos patognomónico de la enfermedad. La disección del nervio facial en su tronco y sus ramas con electroestimulacion es la forma de quirúrgica de sospecharlo intraoperatoriamente. La descompresión parcial o exeresis completa deberá ser considerado de acuerdo a la experiencia del equipo quirúrgico en reconstrucción nerviosa. La reparación del nervio facial como primera opción debe el injerto inmediato o sutura termino terminal. La neurotización es un procedimiento quirúrgico que le provoca al paciente simetría facial con manejo de oclusión ocular y manejo de comisura bucal, debe ser realizado antes del año de la injuria nerviosa. La rehabilitación del nervio facial necesita de un equipo multidisciplinario y la colaboración permanente del paciente para conseguir los objetivos propuestos.


Schwannoma is a rare pathology of the facial nerve. Its preoperative diagnosis is difficult since it has no symptoms or pathognomonic signs of the disease. The dissection of the facial nerve in its trunk and its branches with electrostimulation is the surgical way to suspect it intraoperatively. Partial decompression or complete exeresis should be considered according to the experience of the surgical team in nerve reconstruction. The repair of the facial nerve as a first option should be the immediate graft or end-to-end suture. Neurotization is a surgical procedure that causes the patient facial symmetry with management of ocular occlusion and management of the corner of the mouth, it must be performed within a year of the nerve injury. The rehabilitation of the facial nerve requires a multidisciplinary team and the permanent collaboration of the patient to achieve the proposed objectives.

ABSTRACT

The evaluation of preventivemeasures and risk factors for anastomotic leakage has been a constant concern among colorectal surgeons. In this context, the description of a new way to perform a colorectal, coloanal or ileoanal anastomosis, known as transanal transection and single-stapled (TTSS) anastomosis, deserves an appreciation of its qualities, and a discussion about its properties and technical details. In the present paper, the authors review themost recent efforts aiming to reduce anastomotic dehiscence, and describe the TTSS technique in a patient submitted to laparoscopic total proctocolectomy with ileal pouch-anal anastomosis for familial adenomatous polyposis. Surgical perception raises important advantages such as distal rectal transection under visualization, elimination of double-stapling lines (with cost-effectiveness and potential protection against suture dehiscence), elimination of dog ears, and the opportunity to be accomplished via a transanal approach after open, laparoscopic, or robotic colorectal resections. Future studies to confirm these supposed advantages are needed. (AU)

ABSTRACT

Introduction: There has been conclusive evidence that defunctioning stoma with either transverse colostomy or ileostomy mitigates the serious consequences of anastomotic leakage. However,whether transverse colostomy or ileostomy is preferred for defunctioning a rectal anastomosis remains controversial. The present study was designed to identify the best defunctioning stoma for colorectal anastomosis. Objective: To improve the quality of life in patients with rectal resection and anastomosis and reduce the morbidity before and after closure of the stoma. Patients and Methods The present study included 48 patients with elective colorectal resection who were randomly arranged into 2 equal groups, with 24 patients each. Group I consisted of patients who underwent ileostomy, and group II consisted of patients who underwent colostomy as a defunctioning stoma for a low rectal anastomosis. All surviving patients were readmitted to have their stoma closed and were followed-up for 6 months after closure of their stomas. All data regarding local and general complications of construction and closure of the stoma of the two groups were recorded and blotted against each other to clarify the most safe and tolerable procedure. Results: We found that all nutritional deficiencies, dehydration, electrolytes imbalance, peristomal dermatitis, and frequent change of appliances are statistically more common in the ileostomy group, while stomal retraction and wound infection after closure of the stoma were statistically more common in the colostomy group. There were no statistically significant differences regarding the total hospital stay and mortality between the two groups. Conclusion and Recommendation: Ileostomy has much higher morbidities than colostomy and it also has a potential risk of mortality; therefore, we recommend colostomy as the ideal method for defunctioning a distal colorectal anastomosis.

ABSTRACT

Abstract Background Colorectal resection anastomosis is the commonest cause of rectal strictures. Anastomotic site ischemia, incomplete doughnuts from stapled anastomosis and pelvic infection, are some of the risk factors that play a role in the development of postoperative rectal strictures. However, the role of diverting stoma in the development of rectal strictures has not been studied extensively. Objectives To study the difference in the occurrence of anastomotic strictures (AS) in patients submitted to low anterior resection (LAR) with covering ileostomy (CI), and to LAR without CI for carcinoma rectum. Methods This was a prospective, comparative case control study carried out at a tertiary care referral center. Low anterior resection with covering ileostomy was performed in patients with rectum carcinoma in the study group, while LAR without covering ileostomy was performed in the control group. The study group had 29 patients, while the control group had 33 patients with rectum carcinoma. Results During themean follow-up period of 9.1months, 8 (28%) patients in the study group and 2 (6%) patients in the control group developed AS (p =0.019). Out of these 8 patients with AS in the study group, 50% had Grade-I AS, 25% had Grade-II AS, while 25% of the patients had Grade-III (severe) AS. However, both patients who developed AS in the control group had a mild type (Grade I) of AS. Conclusion Covering ileostomy increases the chances of AS formation after LAR for rectum carcinoma. Also, the SKIMS Clinical Grading of Rectal Strictures is a simple and


Resumo Introdução A anastomose de ressecção colorretal é a causa mais comum de estenoses retais. A isquemia do local da anastomose, donuts (anéis) incompletos de anastomose grampeada e infecção pélvica são alguns dos fatores de risco que desempenham um papel no desenvolvimento de estenoses retais pós-operatórias. No entanto, o papel do estoma de desvio no desenvolvimento de estenoses retais não foi estudado extensivamente. Objetivos Estudar a diferença na ocorrência de estenoses anastomóticas (EA) em pacientes submetidos à ressecção anterior baixa (LAR) com ileostomia de proteção e a LAR sem ileostomia de proteção para carcinoma de reto. Métodos Este foi um estudo prospectivo e comparativo de caso-controle realizado em um centro de referência de atenção terciária. A ressecção anterior baixa com ileostomia de proteção foi realizada em pacientes com carcinoma de reto no grupo de estudo, enquanto LAR sem ileostomia de proteção foi realizada no grupo controle. O grupo de estudo tinha 29 pacientes, enquanto o grupo controle tinha 33 pacientes com carcinoma de reto. Resultados Durante o período de acompanhamento médio de 9, 1 meses, 8 (28%) pacientes no grupo de estudo e 2 (6%) pacientes no grupo controle desenvolveram EA (p=0,019). Destes 8 pacientes com EA no grupo de estudo, 50% tinham EA de Grau I, 25% tinhamEA de Grau II, enquanto 25% dos pacientes tinham EA de Grau III (grave). No entanto, ambos os pacientes que desenvolveram EA no grupo de controle tinham um tipo leve (Grau I) de EA. Conclusão A ileostomia de proteção aumenta as chances de formação de AS após LAR para carcinoma de reto. Além disso, o SKIMS Clinical Grading of Rectal Strictures é uma ferramenta simples e útil disponível para cada cirurgião para graduar, classificar e monitorar as estenoses retais pós-operatórias.

ABSTRACT

Abstract Introduction Colorectal cancer is the second most common type of cancer and the third leading cause ofmortality due to cancers. Anastomosis leak after proctectomy is a dangerous complication that must be managed carefully. The aim of the present study was to assess the procedure of resection and pull-through of the new rectum after anastomosis leak in patients after proctectomy. Methods and Materials This was a cross-sectional study. Patients who visited the Firoozgar Hospital between 2015 and 2018 for rectal cancer surgery and had anastomosis leak entered the study. All patients underwent resection of the residue of rectum and pull-through of colon. Results In the present study, out of the 110 cases who underwent proctectomy, 12 patients with postoperative anastomosis leak were reported. Five (41.7%) were male and 7 (58.3%) were female. Themean age of the patients was 41.5 ± 4.3 years (33-51). Resection of the new rectum and pull-through anastomosis were performed for these 12 patients. No major intraoperative complication occurred. Postoperative course was uneventful in all patients. Discussion Resection of residue of rectum and pull-through in patients with anastomosis leak can be done after rectal cancer surgery. This method is superior to abdominopelvic resection in many aspects, especially regarding accessibility to the new rectum by rectal exam or endosonography to assess recurrence or a relative continence after closure of ostomy.


Resumo Introdução O câncer colorretal é o segundo tipo de câncer mais comum, e a terceira principal causa de mortalidade por câncer. O vazamento da anastomose após a proctectomia é uma complicação perigosa, que deve ser tratada com cuidado. O objetivo do presente estudo foi avaliar o procedimento de ressecção e abaixamento do novo reto após vazamento de anastomose em pacientes submetidos à proctectomia. Métodos e Materiais Este foi um estudo transversal que incluiu pacientes que compareceram ao Firoozgar Hospital entre 2015 e 2018 submetidos a cirurgia de câncer retal e com vazamento de anastomose. Todos os pacientes foram submetidos a ressecção do resíduo do reto e abaixamento do cólon. Resultados No presente estudo, dos 110 casos submetidos a proctectomia, 12 pacientes tiveram vazamento de anastomose pós-operatório: 5 (41,7%) do sexo masculino e 7 (58,3%) do sexo feminino. A idade média dos pacientes foi de 41,5 ± 4,3 anos (gama: 33 a 51 anos). A ressecção do reto novo e a anastomose por abaixamento foram realizadas nesses 12 pacientes. Nenhuma complicação intraoperatória mais grave ocorreu. No pós-operatório, não houve intercorrências em nenhum dos pacientes. Discussão A ressecção de resíduo retal e o abaixamento em pacientes com vazamento de anastomose pode ser feita após cirurgia de câncer retal. Este método é superior à ressecção abdominopélvica em muitos aspectos, especialmente quanto à acessibilidade ao novo reto por exame retal ou endossonografia para avaliar a recorrência ou uma continência relativa após o fechamento da ostomia.

ABSTRACT

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

ABSTRACT

ABSTRACT Purpose: restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice in some cases of familial adenomatous polyposis (FAP) and ulcerative colitis (UC). IPAA allows complete removal of the diseased colon and rectum, however, it is associated with substantial morbidity and potential consequences to patients' quality of life (QoL). Aims: to evaluate the surgical results, functional outcomes and QoL after IPAA; and to examine the impact of surgical complications upon QoL. Methods: we reviewed the records of 55 patients after IPAA, with emphasis on surgical outcomes. Forty patients answered the questionnaires. The Cleveland Global Quality of Life (CGQL), Inflammatory Bowel Disease Questionnaire (IBDQ), and Short Form 36 Health Survey Questionnaire (SF36). Results: the average age was 42.1±14.1 years. 63.6% of the patients were male, and 69.1% had FAP. Operative mortality was 1.8% and overall morbidity was 76.4%. Anastomotic leakage was the most frequent early complication (34.5%). Pouchitis (10.8%) and small bowel obstruction (9.1%) were the most common late complications. Patients with UC had the most severe complications (p=0.014). Pelvic complications did not have a negative effect on functional outcomes or QoL scores. Female patients had decreased pouch evacuation frequency, fewer nocturnal bowel movements, decreased bowel symptom impact on QoL (p=0.012), and better CGQL (p=0.04). Patients with better education had better QoL scores, and patients who had their pouches for more than five years scored lower. Conclusion: the high morbidity has no impact on function or QoL. Bowel function is generally acceptable. QoL is good and affected by sex, education and time interval since IPAA.


RESUMO Objetivo: a Proctocolectomia com reservatório ileoanal (PCT-RIA) é método de escolha em alguns casos de Polipose Adenomatosa Familiar (PAF) e Retocolite Ulcerativa (RCU). Embora tenha potencial curativo, apresenta morbidade considerável e pode afetar a qualidade de vida (QV) dos pacientes. Objetivos: avaliar resultados cirúrgicos e impacto das complicações pélvicas na função intestinal e QV. Métodos: foram avaliados retrospectivamente 55 pacientes submetidos a PCT-RIA, de janeiro de 2003 até abril de 2017, com ênfase na técnica operatória e morbidade. Quarenta pacientes responderam aos questionários Cleveland Global Quality of Life (CGQL), Inflammatory Bowel Disease Questionnaire (IBDQ) e Short Form 36 Health Survey Questionnaire (SF36). Resultados: A média de idade foi 42,1±14,1 anos, sendo 63,6% do sexo masculino e 69,1% com diagnóstico de PAF. A mortalidade cirúrgica foi 1,8% e morbidade 76,4%. Fístula anastomótica foi a complicação precoce mais frequente (34,5%) e, as tardias foram bolsite (10,8%) e obstrução intestinal (9,1%). As complicações precoces mais graves foram mais frequentes em pacientes com RCU (p=0,014). Não houve impacto das complicações na função intestinal nem na QV. As mulheres apresentaram menor frequência evacuatória e noturna, menor interferência dos sintomas intestinais na QV (p=0,012) e CGQL mais elevado (p=0,04). Melhor QV foi referida pelos pacientes com maior escolaridade e, foi observada piora em pacientes com mais de cinco anos de confecção do RIA. Conclusões: não se evidenciou impacto das complicações na função intestinal nem na QV. A função intestinal é satisfatória e a QV é boa na maioria dos pacientes, sendo influenciada pelo sexo, escolaridade e tempo de confecção do RIA.

ABSTRACT

ABSTRACT Background: although preservation of bowel continuity is a major goal in rectal cancer surgery, a colorectal anastomosis may be considered an unacceptably high-risk procedure, particularly for patients with multiple comorbidities. We aimed to assess rates of surgical complications in rectal cancer patients according to the type of procedure they had undergone. Materials and Methods: this cohort included all rectal cancer patients undergoing elective resection at a referral academic hospital over 16 years. There were three study groups according to the type of performed operation: (1) rectal resection with anastomosis without defunctioning stoma (DS); (2) rectal resection with anastomosis and DS; and (3) Hartmann's procedure (HP). Postoperative complications and clinical outcomes were assessed. Results: four-hundred and two patients were studied. The 118 patients in group 3 were significantly older (>10 years), had higher Charlson Comorbidity Index scores, and more ASA class ≥3 than patients in the other two groups. Sixty-seven patients (16.7%) had Clavien-Dindo complications grade ≥ III, corresponding to an incidence of 11.8%, 20.9%, and 14.4% in groups 1, 2, and 3, respectively (p=0.10). Twenty-nine patients (7.2%) had major septic complications that required reoperation, with an incidence of 10.8%, 8.2% and 2.5% in groups 1, 2 and 3, respectively (p=0.048). Twenty-one percent of the group 2 patients did not undergo the stoma closure after a 24-month follow-up. Conclusion: HP was associated with a lower incidence of reoperation due to intra-abdominal septic complications. This procedure remains an option for patients in whom serious surgical complications are anticipated.


RESUMO Introdução: embora a preservação do trânsito intestinal seja um dos objetivos principais na cirurgia do câncer retal, a anastomose colorretal pode ser considerada um procedimento de altíssimo risco, particularmente para pacientes com múltiplas comorbidades. Nosso objetivo foi avaliar as taxas de complicações cirúrgicas em pacientes com câncer retal de acordo com o tipo de procedimento a que foram submetidos. Materiais e Métodos: esta coorte incluiu todos os pacientes com câncer retal submetidos a ressecção eletiva em hospital universitário de referência ao longo de 16 anos. Houve três grupos de estudo de acordo com o tipo de operação realizada: (1) ressecção retal com anastomose, sem estoma desfuncionalizante (ED); (2) ressecção retal com anastomose e ED; e (3) procedimento de Hartmann (PH). Avaliamos as complicações pós-operatórias e os resultados clínicos. Resultados: estudamos 402 pacientes. O grupo 3 tinha 118 pacientes, estes sendo significativamente mais idosos (>10 anos), com pontuações mais altas no Índice de Comorbidade de Charlson e mais frequentemente classificados como ASA ≥ 3 do que os pacientes dos outros dois grupos. Sessenta e sete pacientes (16,7%) apresentaram complicações de Clavien-Dindo grau ≥ III, correspondendo à incidência de 11,8%, 20,9% e 14,4% nos grupos 1, 2 e 3, respectivamente (p = 0,10). Vinte e nove pacientes (7,2%) apresentaram complicações sépticas graves, necessitando reoperação, com incidência de 10,8%, 8,2% e 2,5% nos grupos 1, 2 e 3, respectivamente (p = 0,048). Vinte e um por cento dos pacientes do grupo 2 não foram submetidos ao fechamento do estoma após acompanhamento de 24 meses. Conclusão: o PH foi associado à menor incidência de reoperação por complicações sépticas intra-abdominais. Este procedimento continua sendo uma opção para pacientes com alto potencial de desenvolver complicações cirúrgicas graves.

ABSTRACT

Based on the principle of magnetic anastomosis technique, the design of magnetic anastomosis system for endoscopic tissue clamping is proposed. The system includes a semi-ring magnet, a special structure transparent cap and a detachable push rod. With the help of the existing digestive endoscopy and endoscopic tissue gripper, the endoscopic close clamping and anastomosis of the bleeding or perforated tissue can be completed. After the anastomosis, the magnet falls off and is discharged through the digestive tract. Animal experiments showed that the system was easy to use, the fistula was clamped firmly, the magnet was discharged for 7~21 days, and there was no magnet retention and digestive tract obstruction. Further safety verification, optimization of endoscopic operation, the system can be used in clinical trial.

ABSTRACT

INTRODUCTION@#Hepatic artery reconstruction is a critical aspect of liver transplantation. The microsurgeon faces several challenges when reconstructing the hepatic artery-the donor hepatic artery stalk is short and often a poor match for the usually hypertrophic recipient vessels. Previous inflammation impedes vessel dissection, and recipient vessels have a tendency to delaminate with manipulation. We review 51 consecutive liver transplantations to highlight these problems and propose strategies for a successful reconstruction of the hepatic artery.@*METHODS@#A prospective study involving all adult patients undergoing liver transplantation at the Singapore General Hospital from January 2015 to December 2018 was undertaken. All hepatic artery anastomoses were performed by 2 microsurgeons at 10x magnification. Patients were started on a standard immunosuppressive regimen. Postoperative ultrasound scans on days 1, 3, 5, 7, 9 and 14 were used to confirm arterial patency.@*RESULTS@#There were 51 patients who underwent liver transplantation during the study period. Of this number, 31 patients received deceased donor grafts and 20 received living donor grafts. A total of 61 anastomoses were performed (5 dual anastomosis, 4 radial artery interposition grafts) with 1 case of hepatic artery thrombosis that was successfully salvaged. The mean (range) postoperative resistive index and hepatic artery peak systolic velocity were 0.69 (0.68-0.69) and 1.0m/s (0.88-1.10m/s), respectively.@*CONCLUSION@#Hepatic artery thrombosis after liver transplantation is poorly tolerated. The challenges of hepatic artery reconstruction in liver transplantation are related to vessel quality and length. The use of microsurgical technique, appropriate recipient vessel selection, minimisation of vessel manipulation with modified instruments, variation in anastomosis techniques, and use of radial artery interpositional grafts are useful strategies to maximise the chances of success.

ABSTRACT

Resumen Objetivo: Determinar las características radiográficas, electrocardiográficas, angiográficas y quirúrgicas de los pacientes operados con coartación aórtica en el Instituto Nacional de Cardiología Ignacio Chávez entre los años 2009 y 2018. Métodos: Se recabaron del expediente electrónico las variables consideradas relevantes para el estudio y se registraron en la hoja de captura Excel previamente diseñada. Se analizaron diversas variables radiográficas, electrocardiográficas, angiográficas y quirúrgicas. Se valoró la evolución clínica posquirúrgica, complicaciones, requerimiento de procedimientos intervencionistas o quirúrgicos, y se valoró la respuesta a estos y también los diferentes desenlaces. Resultados: Se reportan 187 cirugías de pacientes desde los 2 días de vida hasta los 12 años, en donde se mencionan las características radiológicas, electrocardiográficas y edad de presentación. El total de fallecimientos en los 9 años fue de 17 casos, los cuales en su gran mayoría (94%) fueron antes del primer año de vida. La técnica quirúrgica más utilizada (90%) fue la coartectomía extendida con anastomosis terminoterminal. Las complicaciones posquirúrgicas registradas fueron en orden descendente: insuficiencia ventricular izquierda, hipertensión arterial sistémica, insuficiencia renal que requirió diálisis peritoneal, etc. Conclusiones: La población registrada que requirió una intervención quirúrgica en el Instituto Nacional de Cardiología fue en su mayoría «lactante menor¼, con una mediana de 3 meses de edad en el momento de la cirugía. Respecto a la técnica quirúrgica empleada, la que tuvo mejores resultados y que no demostró tener una asociación significativa con el número de defunciones fue la coartectomía extendida con anastomosis terminoterminal.


Abstract Objective: To determine the radiographic, electrocardiographic, angiographic and surgical characteristics of the patients operated with aortic coarctation at the Ignacio Chavez National Institute of Cardiology between 2009 and 2018. Methods: The variables considered relevant for the study were collected from the electronic file, recorded in the previously designed Excel capture sheet. Various radiographic, electrocardiographic, angiographic and surgical variables were analyzed. Post-surgical clinical evolution, complications, requirements for interventional or surgical procedures were assessed, and the response to these as well as the different outcomes was assessed. Results: 187 patient surgeries are reported from 2 days of age to 12 years, where the radiological, electrocardiographic characteristics and presentation age are mentioned. The total number of deaths in the 9 years was 17 cases, which were mostly (94%) before the first year of life. The most commonly used surgical technique (90%) was extended coartectomy with term-terminal anastomosis. The recorded postoperative complications were in descending order: ventricular failure, systemic arterial hypertension, renal failure that required peritoneal dialysis, etc. Conclusions: The registered population that required surgical intervention at the National Institute of Cardiology was mostly a minor infant with a median of 3 months in their surgery age. In view of the surgical technique used, the one that had better results and that did not show a significant association with the number of deaths was the extended coartectomy with end-to-end anastomosis.

ABSTRACT

RESUMEN Antecedentes: la lesión quirúrgica de la vía biliar representa un gran problema de salud y puede surgir ante cualquier cirujano que realice una colecistectomía. Objetivos: el objetivo del trabajo fue presentar nuestra experiencia en reparación de la vía biliar, ana lizando la morbimortalidad y la incidencia de dicha patología en nuestro Servicio. Material y métodos: estudio retrospectivo descriptivo; se tomaron las variables de las historias clínicas de los pacientes en un período de 8 años, de enero de 2011 a julio de 2019 donde fueron admitidos 19 pacientes que presentaron lesión quirúrgica de la vía biliar en el Hospital José Ramón Vidal de la provincia de Corrientes, Argentina. Resultados: 12 pacientes fueron tratados quirúrgicamente mediante hepático-yeyuno anastomosis, 2 por bihepático-yeyuno anastomosis y dos mediante sutura término-terminal bilio-biliar sobre tubo de Kehr. Tres pacientes fueron tratados mediante colocación de stent y dilatación posterior mediante colangiopancreatografia retrógrada endoscópica. Conclusión: los cirujanos deben entrenarse para disminuir al mínimo la posibilidad de una lesión. El objetivo de una colecistectomía debería ser no lesionar la vía biliar.


ABSTRACT Background: Bile duct injury represents a serious health problem and can occur after any cholecystectomy. Objectives: The aim of this study was to report our experience in repairing bile duct injuries analyzing morbidity, mortality and its incidence in our department. Material and Methods: We conducted a retrospective and descriptive study. The information was retrieved form the medical records of 19 patients with bile duct injury hospitalized at the Hospital José Ramón Vidal, Corrientes, Argentina, between January 2011 and July 2019. Results: A Roux-en-Y hepaticojejunostomy was performed in 12 patients, double hepaticojejunostomy in two patients, and two patients were treated with end-to-end ductal anastomosis with suture over a T tube. Three patients underwent endoscopic retrograde cholangiopancreatography with stent placement and dilation. Conclusion: Surgeons should be trained to avoid the possibility of bile duct injury. The main goal of cholecystectomy should be to avoid this complication.

ABSTRACT

Abstract The microscope-assisted coronary artery bypass grafting (CABG) is a special technique of direct myocardial revascularization by the operating microscope using special equipment and atraumatic sutures. This method allows to complete elimination of technical errors during the performance of distal anastomoses and can be used to improve the outcomes and quality of conventional technique of operations. This article focuses on a detailed description of the technique for performing a distal anastomosis using a microsurgical technique and an operating microscope. Immediate results of operations are also reported. The data obtained suggest that microscope-assisted CABG is a safe, effective and reproducible procedure.

ABSTRACT

Introducción: La sigmoidectomía por diverticulitis perforada es una cirugía de urgencia comúnmente realizada por cirujanos generales. Está descripta la correlación positiva entre el volumen del cirujano y los mejores resultados postoperatorios. Sin embargo, existe escasa evidencia de la influencia de la especialización en cirugía colorrectal sobre los resultados de la sigmoidectomía laparoscópica por diverticulitis perforada. Objetivo: Evaluar el impacto de la especialización en cirugía colorrectal en los resultados postoperatorios de la sigmoidectomía laparoscópica por diverticulitis Hinchey III. Diseño: Estudio retrospectivo sobre una base de datos cargada de forma prospectiva. Material y métodos: Se incluyeron pacientes sometidos a sigmoidectomía laparoscópica por diverticulitis perforada Hinchey III. La muestra fue dividida en dos grupos: pacientes operados por un cirujano colorrectal (CC) y aquellos operados por un cirujano general (CG). Las variables demográficas, operatorias y postoperatorias fueron comparadas entre los grupos. El objetivo primario fue determinar si existían diferencias en la proporción de anastomosis primaria, morbilidad y mortalidad a 30 días entre los grupos. Resultados: Se incluyeron 101 pacientes en el análisis; 58 operados por CC y 43 por CG. Los pacientes operados por CC presentaron una mayor proporción de anastomosis primaria (CC: 98,3% vs. CG: 67,4%, p<0,001). Los CG realizaron más estomas (CC: 13,8% vs. CG: 46,5%, p<0,001), presentaron un mayor índice de conversión (CC: 20,6% vs. CG: 39,5%, p=0,03) y una mayor estadía hospitalaria (CC: 6,2 vs. CG: 10,8 días, p<0,001). La morbilidad global (CC: 34,4% vs. CG: 46,5%, p=0.22), dehiscencia anastomótica (CC: 3,5% vs. CG: 6,8%, p=0.48) y la mortalidad (CC: 1,7% vs. CG: 9,3 %, p=0,08) fueron similares entre ambos grupos. Conclusión: La sigmoidectomía laparoscópica de urgencia realizada por CG presenta similar morbilidad y mortalidad postoperatoria que la realizada por CC. Sin embargo, la participación del especialista se asoció a una mayor frecuencia de anastomosis primarias, menos estomas y una estadía hospitalaria más corta.


Background: Sigmoid resection for perforated diverticulitis is one of the most common emergency surgeries and often performed by general surgeons. Relationship between high-volume surgeons and improved postoperative outcomes is well established. However, the influence of colorectal specialization on outcomes after emergency laparoscopic sigmoidectomy for perforated diverticulitis is not well described. Aim: Evaluate the impact of colorectal surgery training on the outcomes after emergency laparoscopic sigmoid resection for Hinchey III diverticulitis. Design: Retrospective analysis of prospectively collected database.Method: Patients undergoing emergent laparoscopic sigmoid resection for perforated (Hinchey III) diverticulitis were identified and stratified by involvement of colorectal or general surgeon. This study was conducted from 2000 to 2018 at a teaching hospital. Primary outcome measures were primary anastomosis, postoperative morbidity and mortality.Results: A total of 101 patients were identified; 58 by colorectal and 43 by general surgeons. Patients in the colorectal surgeon group had higher rates of primary anastomosis (CS: 98, 2% vs. GS: 67, 4%, p<0.001). General surgeons performed more ostomies (CS: 13, 8% vs. GS: 46, 5%, p<0.001), had a higher conversion rate (CS: 20, 6% vs. GS: 39, 5%, p=0.03) and longer mean length of hospital stay (CS: 6, 2 vs. GS: 10, 8 days, p<0.001). Overall morbidity (CS: 34, 4% vs. GS: 46, 5%, p=0.22), anastomotic leak rate (CC: 3,5% vs. CG: 6,8%, p=0.48) and mortality (CS: 1, 7% vs. GS: 9,3 %, p=0.08) were similar between groups. Conclusion: Emergency laparoscopic sigmoid resection by general surgeons wasn ́t associated with higher rates of postoperative morbidity, anastomotic leakage or mortality. However, patients operated by colorectal surgeons had higher rates of primary anastomosis, lower rates of ostomy, conversion and shorter length of hospital stay.

ABSTRACT

Resumen Introducción: Si bien la anastomosis intracorpórea (AI) ha demostrado beneficios clínicos sobre la anastomosis extracorpórea (AE) en la hemicolectomía derecha laparoscópica (HDL), su aplicación ha sido limitada por su dificultad técnica y curva de aprendizaje más larga. El presente estudio busca desarrollar y evaluar un modelo simulado para entrenar este procedimiento. Materiales y Método: Se desarrolló un modelo en base a tejido ex vivo, con colon porcino e intestino bovino, montados en un simulador de laparoscopía. Este se modificó sucesivamente en base a entrevistas semiestructuradas a cirujanos hasta lograr el modelo final. Para evaluar apariencia y reacción al modelo, coloproctólogos, cirujanos y residentes previamente expuestos a entrenamiento simulado, realizaron una ileotransverso anastomosis mecánica en el modelo y luego contestaron una encuesta. Resultados: Doce sujetos participaron. Cuatro coloproctólogos, 4 residentes de coloproctología, 2 residentes de cirugía general, 1 cirujano general y 1 cirujano digestivo. El 91,6% valoró positivamente la ergonomía lograda, mientras que el 83,3% y 75% valoraron positivamente el uso del instrumental y la relación anatómica entre estructuras, respectivamente. Todos los participantes consideraron el modelo útil para entrenar sutura manual laparoscópica, el 91,6% para entrenar enterotomías y 83,3% para entrenar el uso de endograpadora. Todos declararon que el módulo permite entender y reflexionar sobre la técnica propuesta. Conclusión: Este modelo desarrollado sería útil para entrenar habilidades críticas para realizar una AI en HDL. Su incorporación a un programa de entrenamiento en laparoscopía avanzada podría contribuir a acortar la curva de aprendizaje de este procedimiento.


Introduction: Although intracorporeal anastomosis has demonstrated clinical benefits over extracorporeal anastomosis in laparoscopic right hemicolectomy, its application has been limited due to its technical difficulty and longer learning curve. The present study aims to develop and evaluate a simulated model to train this procedure. Materials and Method: An ex vivo tissue model was developed with porcine colon and bovine small bowel mounted in a laparoscopic simulator. This was subsequently modified based on semi-structured interviews to experts until the final model was achieved. To evaluate appearance and reaction to the model, the participants performed an ileocolic mechanical anastomosis in the model and answered a survey. Results: Twelve subjects participated. Four colorectal surgeons, 4 colorectal surgery fellows, 2 residents of general surgery, 1 general surgeon and 1 upper digestive surgeon. Of all subjects, 91.6%, 83.3% and 75% deemed ergonomics achieved, the use of instruments, and the anatomical relationship between structures as similar to reality, respectively. All participants deemed the model useful to train laparoscopic manual suturing, while 91.6% and 83.3% of them considered it useful to train enterotomies and the use of an endostapler, respectively. All declared that the model allows to understand the proposed technique. Conclusion: This model would be useful to train critical skills to perform an intracorporeal anastomosis in laparoscopic right hemicolectomy. Its incorporation into an advanced simulated laparoscopy training program could help shorten the learning curve of this procedure.

ABSTRACT

ABSTRACT Purpose: To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit. Materials and methods: Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, deterioration of the upper tract, intraoperative blood loss and patient-reported quality of life (HRQOL). The modified Wallace 1 technique involved eversion of the ureteral plate and bowel mucosa edges, which were anastomosed together in running fashion, while the outher anastomotic wall was augmented with sero-serosal interrupted sutures. Results: The mean (SD) follow-up time was 26.1 (5.7) months in group I and 25.2 (4.8) months in group II, during which, anastomotic stricture was observed in 8 patients (12%) from the first and 2 patients (3%) from the second group (p < 0.05). The anastomotic leakage rate was significantly higher in first group (17% vs. 8.5%, p< 0.05), while patient-reported HRQOL outcomes were similar between groups after the 12 month follow-up period. Conclusions: By using a modified Wallace technique, we were able to significantly lower anastomotic stricture and anastomotic leakage rates, which are major issues in minimizing both short- and long-term postoperative complications.
