Post-Cholecystectomy Surgical Re-intervention for Cystic Duct Remnant - An Experience.

Background: In laparoscopic cholecystectomy, cystic duct is typically separated closer to the gallbladder to prevent iatrogenic common bile duct damage, leaving behind a long cystic duct remnant that can potentially lead to postcholecystectomy syndrome. Methods: A retrospective analysis of the data from 2010 to 2021 was undertaken at SKIMS Medical College, Srinagar, Kashmir, India, of all the cases who had been surgically re-explored for cystic duct remnants post-laparoscopic cholecystectomy. Results: Twenty cases of both genders underwent surgical reintervention for cystic duct remnant. The mean time of presentation after an index cholecystectomy was 2 years. Surgical operations were conducted through an open approach in 17 (85%) and by laparoscopy in 3 (15%). 95% of patients were symptom-free in the follow-up period. Conclusions: Cystic duct remnants should be considered if a patient report with symptoms suggestive of postcholecystectomy syndrome. The condition once diagnosed, can be managed safely by surgical reintervention.

Cotite Apendicular - Relato de Caso / Stump appendicitis - Case Report

Cotite apendicular é uma rara complicação pós-apendicectomia, que se caracteriza por ser uma inflamação do coto apendicular remanescente devido à obstrução do seu lúmen, geralmente por um fecalito. Isso aumenta a pressão intraluminal, prejudica a drenagem venosa e facilita subsequente infecção bacteriana. Em virtude da baixa incidência desta patologia, seu diagnóstico costuma ser tardio, podendo gerar consequências deletérias ao paciente. Os achados clínicos e radiológicos são semelhantes aos da apencidite aguda, e o tratamento é a reintervenção cirúrgica e complementação da apendicectomia, excisando o coto remanescente.

Stump appendicitis is a rare post-appendectomy complication characterized as an inflammation of the remaining appendicular stump due to obstruction of its lumen, usually by a fecalith. Which increases intraluminal pressure, impairs venous drainage, and facilitates subsequent bacterial infection. Due to the low incidence of this pathology, its diagnosis is usually late, and it can have deleterious consequences for the patient. The clinical and radiological findings are similar to those of acute appendicitis, and the treatment is surgical reintervention and complementary appendectomy, excising the remaining stump.

Pancreatectomia secundária à aderência após ovário-histerectomia em uma cadela - relato de caso / Pancreatectomy secondary to adherence after ovary-histerectomy in a female dog - a case report / Pancreatectomía secundaria a una adherencia después de ovario histerectomía en una perra ­ relato de caso

O procedimento cirúrgico eletivo realizado com maior frequência na rotina veterinária é a ovário-histerectomia (OVH), com isso há uma alta casuística de complicações pós-operatórias. Entre elas, pode-se citar piometra de coto, ligadura acidental de ureter, síndrome do ovário remanescente, formação de granulomas inflamatórios e aderências a órgãos. Os granulomas de coto ovariano são formados, geralmente por um fio de sutura utilizado inadequadamente, ou a um sítio de infecção. Tais granulomas podem levar à aderências, inclusive a órgãos próximos ao sítio cirúrgico. O presente relato refere-se a uma cadela, que apresentou granulomas ovarianos com aderências no pâncreas e em diversos órgãos após a ovário-histerectomia. Para a solução do caso, foi realizado uma celiotomia exploratória para avaliação da cavidade abdominal, retirada das aderências das estruturas e das formações granulomatosas, sendo necessária a realização de uma pancreatectomia parcial para a retirada completa do granuloma. Após a cirurgia, o paciente desenvolveu quadro de pancreatite, uma complicação muito comum em cirurgias pancreáticas. Ainda assim, o resultado foi considerado satisfatório, pois a pancreatite foi solucionada e os granulomas removidos, e até a última revisão pós-operatória, o paciente encontrava-se bem clinicamente. A OVH é uma das cirurgias mais realizadas na rotina médico veterinária, ainda assim é negligenciada em diversos quesitos. Portanto, há a necessidade dessa técnica cirúrgica e suas possíveis complicações serem realizadas de maneira correta e efetiva.(AU)

The most frequently elective surgical procedure performed in the veterinary routine is the ovary hysterectomy (OVH). As such, there is a high number of post-operative complications, which include stump pyometra, accidental ligation of the ureter, remnant ovary syndrome, formation of inflammatory granulomas, and organ adhesions. Ovarian stump granulomas are usually formed by suture which has been improperly used, or to infection. Such granulomas can lead to adhesions, also affecting organs close to the surgical site. This report refers to a female dog that presented ovarian granulomas with adhesions to the pancreas and to several organs after ovary-hysterectomy. In order to solve the case, an exploratory celiotomy was performed to assess the abdominal cavity, removing the adhesions of the structures and granulomatous formations, which required the performance of a partial pancreatectomy for the thorough removal of the granuloma. After surgery, the patient developed pancreatitis, a very common complication in pancreatic surgery. Even so, the result was considered satisfactory, as the pancreatitis was resolved and the granulomas removed and until the last post-operative review, the patient was clinically well. OVH is one of the most commonly performed surgeries in the veterinary medical routine, yet it is neglected in several aspects. Therefore, there is a need for the surgical technique and its possible complications to be performed correctly and effectively.(AU)

El procedimiento quirúrgico electivo que se realiza con mayor frecuencia en la rutina veterinaria es la ovario-histerectomía (OVH), con que existe un elevado número de complicaciones postoperatorias. Estos incluyen piometra del muñón, ligadura accidental del uréter, síndrome de ovario remanente, formación de granulomas inflamatorios y adherencias a órganos. Los granulomas del muñón ovárico se forman por lo general por una sutura mal utilizada o en un sitio de infección. Dichos granulomas pueden provocar adherencias, incluso a órganos cercanos al sitio quirúrgico. El presente informe se refiere a una perra, quien presentó granulomas ováricos con adherencias en el páncreas y en varios órganos tras ovario histerectomía. Para la solución del caso se realizó una celiotomía exploratoria para acceder la cavidad abdominal, removiendo las adherencias de las estructuras y formaciones granulomatosas, requiriendo la realización de una pancreatectomía parcial para la extirpación completa del granuloma. Después de la cirugía, la paciente desarrolló pancreatitis, una complicación muy común en la cirugía pancreática. Aun así, el resultado se consideró satisfactorio, ya que se resolvió la pancreatitis y se retiraron los granulomas, y hasta la última revisión postoperatoria la paciente se encontraba clínicamente bien. La OVH es una de las cirugías que se realizan con mayor frecuencia en la rutina médica veterinaria, pero se descuida en varios aspectos. Por tanto, existe la necesidad de que esta técnica quirúrgica y sus posibles complicaciones se realicen de forma correcta y eficaz.(AU)

Hallazgos imagenológicos de la apendicitis de muñón / Imagenological findings of stump apendicitis

Resumen La apendicitis del muñón es una complicación poco frecuente de la apendicectomía. Puede aparecer desde unas semanas a varios años luego del procedimiento quirúrgico. Para arribar a su diagnóstico es necesario un alto índice de sospecha. El objetivo de esta publicación es hacer una reseña de dos casos de esta entidad ocurridos en nuestra institución y mencionar sus hallazgos imagenológicos más frecuentes. La tomografía computarizada es un excelente método para valorar esta entidad, no solo para su diagnóstico sino también para descartar otras patologías que presentan un cuadro clínico similar.

Abstract Stump appendicitis is a rare complication of appendectomy. It may develop from a few weeks to several years after the surgical procedure. To achieve its diagnosis a high index of suspicion is necessary. The objective of this publication is to make a re view of two cases of this entity that occurred in our institution and to mention its most frequent imaging findings. Computed tomography is an excellent method to assess this entity, not only for its diagnosis but also to rule out other pathologies that present similar clinical features.

Infección de un muñón por Leuconostoc spp, reporte de un caso y revisión de la literatura / Infection of a stump by Leuconostoc, a case report and review of the literature

Resumen La infección del muñón después de amputaciones traumáticas tiene una prevalencia hasta del 34%. Las bacterias más frecuentemente aisladas son Staphylococcus aureus, Enterobacterales como Escherichia coli; Pseudomonas aeruginosa, entre otras. Estas infecciones ocurren por la inoculación directa en el momento del trauma o por gérmenes nosocomiales; la realización de curaciones de las heridas con emplastos vegetales es una práctica aún frecuente en zonas rurales de nuestro país pero su relación con infección del sitio operatorio ha sido poco explorada en la literatura. Leuconostoc spp. es un coco Gram positivo encontrado en territorio agrícola y utilizado en la industria de alimentos. Se presenta un caso de infección de un muñón transfemoral por Leuconostoc, después de una amputación traumática del miembro inferior en una paciente previamente sana con una posible asociación a curaciones con emplastos vegetales.

Abstract Infection of a traumatic amputation stump has a prevalence of 34%. The most common bacteria isolated are Staphylococcus aureus, Pseudomonas aeruginosa and Enterobacterales such as Escherichia coli. These infections occur by direct inoculation in the moment of the trauma or by nosocomial germs. Infections secondary to manipulation of the wounds with vegetable plasters have few case reports in the literature. Leuconostoc spp. is a Gram-positive coccobacillus commonly found in agricultural territory and used in the food industry. There are few case reports in the literature about bone infections by Leuconostocs pp. We present a case of an infection of the operative site of a transfemoral stump by Leuconostoc spp. after a traumatic amputation of the lower limb in a previously healthy patient who had a possible association to cures with vegetable plasters.

Occlusion with Bronchial Covered Stent in the Management of Bronchial Stump Fistula after Right Middle and Lower Lobectomy: A Case Report and Literature Review / 中国肺癌杂志

BACKGROUND@#Bronchopleural fistula (BPF) is one of the most serious and rare postoperative complications, especially the bronchial stump fistula after lobectomy/pneumonectomy. Common treatment options include conservative medical treatment combined with surgery. However, due to the delayed healing of the fistula, the chest cavity continues to communicate with the outside world, and the patient is prone to complicated with severe thoracic infection and respiratory failure, so that the physical condition can hardly tolerate the second surgical procedure. Endoscopic treatment provides a new option for the treatment of this complication.@*METHODS@#A case of right pulmonary squamous cell carcinoma was admitted to the Department of Thoracic Surgery II, Peking University Cancer Hospital in June 2016. The diagnosis and treatment was retrospectively analyzed, and the literature was reviewed.@*RESULTS@#A 65 year old male patient was admitted to hospital because of "cough with blood in sputum for 3 months". Chest computed tomography (CT) showed soft tissue density mass shadow in the right lower lobe. A tumor could be seen in the opening of the right middle lobe and basal segment of lower lobe. Biopsy confirmed squamous cell carcinoma. Diagnosis consideration: squamous cell carcinoma of the middle and lower lobe of the right lung (cT2aN2, IIIa). Patients received gemcitabine plus cisplatin neoadjuvant chemotherapy for 2 cycles, and the effect of chemotherapy showed stable disease (SD). Four weeks after chemotherapy, the patient underwent video-assisted thoracic surgery (VATS) assisted right middle and lower lobectomy and mediastinal lymph node dissection. On the 5th day after operation, the patient developed acute respiratory distress syndrome (ARDS) and was transferred to intensive care unit (ICU) again after endotracheal intubation. On the 7th day after operation, the patient developed a right intermediate trunk bronchial stump fistula, but due to ARDS, the patient's physical condition could not tolerate the second operation. Under the support of extracorporeal membrane oxygenation (ECMO), a membrane covered, expandable, hinged stent was inserted into the intermediate trunk bronchial stump through rigid bronchoscope, and was successfully blocked. Due to no improvement in ARDS and irreversible pulmonary interstitial fibrosis, the patient received double lung transplantation successfully after systemic anti-infection treatment.@*CONCLUSIONS@#Endoscopic implantation of covered stent is a simple, safe and effective method for closure of bronchial stump fistula. When the patient's clinical situation is not suitable for immediate surgery, endoscopic stent implantation can be used as a preferred treatment method to create opportunities for follow-up treatment.

Management of rectal stump leak following emergency Hartmann's procedure / Gerenciamento do vazamento do coto retal após o procedimento de emergência de Hartmann

ABSTRACT We report on the management of three cases of rectal stump leak and sepsis following urgent Hartmann's procedure for perforated sigmoid diverticulitis or large bowel obstruction. Two patients had significant risk factors for poor tissue healing. All patients developed features of sepsis and computer tomography scans demonstrated rectal stump leak with adjacent collections. All patients required reoperation for drainage and washout of abscess. An intraperitoneal catheter system was introduced together with drains in order to continue on the ward until tract was formed. There was no mortality and minimal morbidity. The key to management of rectal stump leak is the early and aggressive drainage of the associated collection and continued irrigation of the stump.

RESUMO Relatamos o tratamento de três casos de vazamento de coto retal e sepse após o procedimento de urgente de Hartmann para diverticulite sigmoide perfurada ou obstrução do intestino grosso. Dois pacientes apresentaram fatores de risco significativos para uma má cicatrização tecidual. Todos os pacientes desenvolveram características de sepse e tomografia computadorizada demonstraram vazamento de coto retal com coleções adjacentes. Todos os pacientes necessitaram de reoperação para drenagem e lavagem do abscesso. Um sistema de cateter intraperitoneal foi introduzido junto com os drenos para continuar na enfermaria até a formação do trato. Não houve mortalidade e morbidade mínima. A chave para o gerenciamento do vazamento de coto retal é a drenagem precoce e agressiva da coleta associada e a irrigação contínua do coto.

Stump appendicitis

Appendectomy is one of the commonest abdominal operation performed all over the world. Stump appendicitis is one of the uncommon complications of appendectomy. The diagnosis of stump appendicitis is delayed due to low index of suspicion by virtue of the fact that an appendectomy has already been done. The clinical presentation exactly simulates acute appendicitis. Contrast enhanced computed tomography is diagnostic. Completion appendectomy either open or laparoscopic is the mainstay of treatment. Awareness regarding the possible aetiology, diagnosis and management is essential for avoiding delay in the diagnosis.

Stump appendicitis single centre experience: a retrospective study

Background: Appendicectomy is the most common surgical procedure done for acute appendicitis worldwide. However, one among 50000 appendicectomy patients may present with recurrent abdominal pain, requiring hospitalization as stump appendicitis and may need completion appendicectomy. There are a few reports addressing management of stump appendicitis in the literature. Here we present our experience of laparoscopic completion appendicectomy over ten-year duration.Methods: A retrospective evaluation of records of appendicectomy from January 2008 to December 2018. All patients who had stump appendicitis as diagnosis and those who underwent completion appendicectomy were included. There were no exclusions. Details pertaining to presentation, duration of symptoms, records of previous surgery, perioperative and postoperative data was recorded, including follow-up of at least six months.Results: All 15 patients were managed by laparoscopic completion appendicectomy. Patients age range from 12 to 58 years, 12 were males and 3 female, duration of symptoms was from two to ten days, previous appendicectomy was done 4 to 84 months before, nine were diagnosed by ultrasonography of abdomen and six by CT scan, stump size ranged from 1 to 3.6 cm, mean operating time was 86.4 mins (range, 60-120 minutes). Duration of hospital stay was 3 to 5 days. There were no perioperative morbidity or mortality.Conclusions: Laparoscopic approach of completion appendicectomy is safe for management of stump appendicitis.

Stump appendicitis: an uncommon dilemma

Stump appendicitis is one of the rare delayed complications post appendectomy with a reported incidence of 1 in 50,000 cases. Stump appendicitis can present as a diagnostic dilemma if the treating clinician is unfamiliar with this rare clinical entity. The purpose of this paper is to review current data on stump appendicitis and analyse published cases.

A study to evaluate the safety and cost effectiveness of preformed catgut endoloops and polyglactin 910 extracorporeal ligation in the management of appendicular stump closure in laparoscopic appendicectomy

Background: The most essential component of laparoscopic appendectomy is the closure of appendicular stump. Failure of which can result in catastrophic complications including intra-abdominal and surgical site infections and rarely faecal fistula. The aim of this study was to verify the effectiveness of preformed catgut endoloop and extracorporeal polyglactin 910 for appendicular stump closure.Methods: This prospective study was carried out in 64 patients. We compared patient demographics, duration of surgery, intra and post-operative complications, hospital stay and cost of surgery between the two groups.Results: A total of sixty-four patients were finally included in the analysis, catgut group (n=34), polyglactin 910 group (n=30). The demographics between the two groups were similar. The mean age in catgut group was 23.94 years and polyglactin 910 groups was 23.33 years. Mean duration of surgery was 41.6 and 41.8 minutes in catgut and endoloop group respectively. Mean hospital stay was 3 days. There was no mortality but complications were seen in 6 patients. However, there was no statistical significance in between the two groups with any of the parameters studied.Conclusions: Multiple studies have demonstrated safety and effectiveness of various techniques of appendicular stump. The use of extracorporeal single polyglactin 910 extracorporeal suture knot is safe and cost-effective technique for closure of appendicular stump in rural and resource poor regions.

Risk Factors for Duodenal Stump Leakage after Laparoscopic Gastrectomy for Gastric Cancer

PURPOSE: Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC).MATERIALS AND METHODS: Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Roux-en-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression.RESULTS: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2–12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment.CONCLUSIONS: The risk factors of DSL were BMI ≥24 kg/m², elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

It’s Complicated: A Case Report of a Patient with Colo-cutaneous Fistula connected to the Appendiceal Stump

@#INTRODUCTION: Colo-cutaneous fistula is a very rare complication of colonic diverticular disease, occurring in approximately one percent of cases either spontaneously or after surgical or drainage procedure. Herein we describe a patient with a colo-cutaneous fistula from the sigmoid to the appendiceal stump in a post-appendectomy patient which also exits to the skin at the post-operative site. CASE PRESENTATION: The patient is a 76-year-old Filipino male who had appendectomy five months earlier and a history of diverticulitis, and presented with a subcutaneous abscess at the post-operative site. The abscess was drained, a colocutaneous fistula was radiographically established, and the surgical site was explored. Intraoperative findings showed the presence of multiple colonic diverticuli and a sigmoidcutaneous fistula on the right lower abdominal quadrant. Interestingly, an incidental descending colon mass was also noted at the splenic flexure measuring approximately 2x3 cm to which frozen section revealed adenocarcinoma which was not seen in pre-operative CT scans. An extended left hemicolectomy was performed, and no postoperative complications were noted. At present three years later, he fares well without any signs and symptoms of the disease. CONCLUSION: Diverticulitis is a common condition in the older age group that needs to be considered in patient management. Colo-cutaneous fistula may be a rare complication of the disease but should be part of our differentials as internists in working up patients presenting with persistently draining superficial wound that either occurs spontaneously or post-operatively. Patients with diverticulitis also have increased risk of colorectal cancer and diagnostic imaging may not always differentiate the two entities, thus colonoscopy should be done if possible.

Apendicitis del muñón: reporte de un caso y revisión de la literatura / Stump appendicitis: case report and literature review

La apendicitis del muñón es una rara entidad, de la cual se desconoce su incidencia, con alrededor de 100 casos reportados en la literatura médica. Requiere un alto grado de sospecha clínica para su correcta identificación. El tratamiento recomendado es quirúrgico. Se presenta el caso de un paciente de 26 años, con antecedente de apendicectomía hace 17 años, con cuadro de dolor abdominal en fosa iliaca derecha y signos apendiculares positivos en el examen físico. La Tomografía Axial Computarizada demostró una colección con gas y fecalitos en su interior, localizada en fosa iliaca derecha, planteándose un diagnóstico de apendicitis del muñón. Se realizó una laparotomía exploratoria, evidenciándose un muñón apendicular perforado en su tercio proximal, por lo que se completó la apendicectomía del muñón. El informe histopatológico reportó un muñón apendicular con infiltrado mono y polimorfo nuclear, que compromete el espesor de la pared. El paciente fue dado de alta con evolución dentro de parámetros esperados y fue remitido a control y seguimiento por Consulta Externa.

Stump appendicitis is a rare entity, of which its incidence is unknown, with about 100 cases reported in the medical literature, which requires a high degree of clinical suspicion for proper identification. The recommended treatment is surgical. The case of a 26-year-old patient with an appendectomy antecedent 17 years ago, with abdominal pain in right lower quadrant and positive appendicular signs on the physical exam is presented. Computerized Axial Tomography demonstrated a collection of gas and fecalites inside, located in right lower quadrant, considering a diagnosis of stump appendicitis. An exploratory laparotomy was performed, with an appendicular stump perforated in its proximal third, and the stump appendectomy was completed. The histopathological report reported an appendicular stump with mono and polymorph nuclear infiltrate, which compromises the thickness of the wall. The patient is discharged with evolution within expected parameters and is referred to control and follow-up by External Consultation.

Surgical results of remnant gastric cancer treatment / Resultados cirúrgicos do tratamento dos tumores do coto gástrico

ABSTRACT Background: remnant gastric cancer (RGC) develops five years or later after previous resection for benign or malignant lesion. The treatment is performed through completion total gastrectomy (CTG) with radical lymphadenectomy. Some reports consider this procedure may be associated with higher rates of morbidity and mortality. Objective: to evaluate surgical results and survival after CTG in patients with RGC. Methods: 54 patients who underwent CTG between 2009 and 2019 were included in the study. As a comparison group 215 patients with primary gastric cancer (PGC) who underwent total gastrectomy (TG) in the same period were selected. Results: among the initial characteristics, age (68.0 vs. 60.5; p<0.001), hemoglobin values (10.9 vs. 12.3; p<0.001) and body mass index (22.5 vs. 24.6; p=0.005) were different between the RGC and PGC groups, respectively. The most frequent postoperative complications were related to pulmonary complications, infection and fistula in both groups. There was a higher incidence of esophagojejunal fistula in the CTG group (14.8% vs 6.5%, p=0.055). Perioperative mortality was higher in RGC patients (9.3% vs. 5.1%), but without significance (p=0.329). Hospital length of stay, postoperative complications graded by the Clavien-Dindo classification, mortality at 30 and 90 days were not different between groups. There was no significant difference in disease-free and overall survival between RGC and PGC groups. Conclusion: despite previous reports, surgical results and survival were similar between groups. Higher risk of esophagojejunal fistula must be considered.

RESUMO Antecedentes: o câncer do coto ou remanescente gástrico (CRG) se desenvolve cinco anos ou mais após a ressecção gástrica por lesão benigna ou maligna. O tratamento é realizado através da gastrectomia total complementar (GTC) com linfadenectomia. Alguns relatos consideram que esse procedimento pode estar associado a maiores taxas de morbimortalidade. Objetivo: avaliar os resultados cirúrgicos e a sobrevida após GTC em pacientes com CRG. Métodos: 54 pacientes submetidos a GTC entre 2009 e 2019 foram incluídos no estudo. Como grupo de comparação, foram selecionados 215 pacientes com câncer gástrico primário (CGP) submetidos à gastrectomia total (GT) no mesmo período. Resultados: dentre as características iniciais, a idade média (68,0 vs. 60,5; p <0,001), os valores de hemoglobina (10,9 vs. 12,3; p <0,001) e o índice de massa corporal (22,5 vs. 24,6; p = 0,005) diferiram entre os grupos CRG e CGP, respectivamente. As complicações pós-operatórias mais frequentes foram pulmonares, infecciosas e fístulas nos dois grupos. Houve maior incidência de fístula esofagojejunal no grupo GTC (14,8% vs 6,5%, p = 0,055). A mortalidade perioperatória foi maior nos pacientes com CRG (9,3% vs. 5,1%), mas sem significância (p = 0,329). O tempo de internação hospitalar, complicações pós-operatórias (Clavien-Dindo), mortalidade aos 30 e 90 dias não foram diferentes entre os grupos. Não houve diferença significativa na sobrevida livre de doença e global entre os grupos CRG e CGP. Conclusão: apesar dos relatos anteriores, os resultados cirúrgicos e a sobrevida foram semelhantes entre os grupos. Maior risco de fístula esofagojejunal dever ser considerado.

Apendicitis aguda recurrente en pacientes apendicectomizados / Relapsed appendicitis in appendectomized patients

RESUMEN Introducción: La apendicitis aguda es la causa más común de abdomen agudo, que precisa de tratamiento quirúrgico mediante apendicectomía abierta o laparoscópica. La apendicitis del muñón o recurrente, en la que ocurre la inflamación del remanente apendicular, es una complicación tardía infrecuente de la apendicectomía. Objetivo: Identificar las posibles causas de la apendicitis recurrente, así como las medidas relacionadas con su prevención. Métodos: Se realizó una revisión de la literatura actualizada sobre el tema en formato digital, en publicaciones en idioma inglés y español. Conclusiones: La prevención de la apendicitis del muñón se basa en resecar el apéndice a menos de 0,5 cm de su base; los pacientes, con frecuencia, presentan síntomas análogos a los de antes de la primera cirugía, sin embargo, existe un incremento del riesgo de peritonitis y de graves complicaciones debido al retraso diagnóstico y terapéutico; es una causa poco frecuente de dolor abdominal en pacientes apendicectomizados, por lo que se debe guardar una alta sospecha para su diagnóstico precoz y tratamiento oportuno(AU)

ABSTRACT Introduction: Acute appendicitis is the most common cause of acute abdomen, which requires surgical treatment by open or laparoscopic appendectomy. Recurrent appendicitis of the stump, in which inflammation of the appendicular remnant occurs, is an infrequent late complication of appendectomy. Objective: To identify the possible causes of recurrent appendicitis, as well as the measures related to its prevention. Methods: A review of the updated literature on the subject was carried out in digital format, in publications in English and Spanish. Conclusions: Prevention of appendicitis of the stump is based on resecting the appendix less than 0.5 cm from its base; Patients frequently present symptoms similar to those before the first surgery, however, there is an increased risk of peritonitis and serious complications due to delayed diagnosis and therapy; It is a rare cause of abdominal pain in appendectomized patients, so high suspicion should be kept for its early diagnosis and prompt treatment(AU)

The effect of cerebral oximeter use on the shunt placement concerning carotid endarterectomy surgery

Background: During carotid arterial endarterectomy (CAE) surgery, an intraluminal shunt is used to prevent hypoperfusion, which can be caused by a cross-clamping cerebral ischemia. However, routine shunt use is not recommended. Various cerebral monitoring techniques are used to determine the need for shunt placement. In this study, retrospective analysis of data on the efficacy of cerebral oximetry in the decision of shunt use during elective CAE surveys was planned. Materials and Methods: We collected data on 68 patients operated under general anesthesia between December 2016 and December 2017. Patients were evaluated for near infrared spectrometry (NIRS) and stump pressure values and whether shunt was placed or not. Results: Eight (11.7%) patients were shunting. NIRS value after cross-clamping was lower in patients with shunt. Stump pressure values were below 40 mmHg. Conclusions: Cerebral monitoring in elective CAE operations has great importance in determining the necessity of using intraluminal shunt to reduce the complications that may occur.

Analysis of prognostic factors for recurrence of vaginal stump in 493 cases of stageⅠ-ⅡA cervical cancer after radical hysterectomy / 中华放射肿瘤学杂志

Objective To explore the prognostic factors for the recurrence of vaginal stump of earlystage cervical cancer after radical hysterectomy and evaluate the effect on clinical prognosis.Methods Clinical data of stage Ⅰ-ⅡA cervical cancer patients undergoing radical hysterectomy in Guizhou Cancer Hospital from January,2007 to December,2016 were retrospectively analyzed.Results A total of 493 patients were enrolled and followed up until May 30,2018.Among them,96.6％(474/493) completed the follow-up.The median age was 45 years.Patients aged 40-50 years had a high incidence rate.In total,451 cases (91.48％) had no recurrence of vaginal stump.The average time without stump recurrence was 51.2 months and the median time without stump recurrence was 44.8 months.Multivariate Cox regression analysis demonstrated that pelvic external irradiation and brachytherapy were the independent prognostic factors for the recurrence of vaginal stump (P=0.000,0.000).Tumor size,lymph node metastasis and pelvic external irradiation were the independent prognostic factors for overall survival (P=0.045,0.022,0.000).Conclusions Pelvic external irradiation and brachytherapy play an extremely pivotal role in reducing the risk of vaginal stump recurrence after radical hysterectomy for patients with stage Ⅰ-Ⅱ A cervical cancer.Tumor size,lymph node metastasis and pelvic external irradiation are the independent prognostic factors for overall survival of patients with stage Ⅰ-Ⅱ A cervical cancer following radical hysterectomy.

Analysis of the poor prognostic factors affecting 48 cases of cervical stump carcinoma / 中华放射肿瘤学杂志

Objective@#To explore the poor prognostic factors of patients with cervical stump carcinoma, aiming to provide certain reference for the clinical diagnosis and treatment.@*Methods@#Clinical data of 48 patients with cervical stump carcinoma admitted to the Affiliated Tumor Hospital of Xinjiang Medical University from January 1, 2005 to December 1, 2016 were retrospectively analyzed. A total of 19 patients (40%) withⅠA-ⅡA stage cervical stump carcinoma were treated with surgery+ adjuvant therapy and 29 patients (60%) in ⅡB-Ⅳ stage received radiotherapy combined with chemotherapy. The median age of onset was 51 years old. Uterine fibroids were the main cause of subtotal hysterectomy. The average time interval from subtotal hysterectomy to definite diagnosis was 10.76 years.@*Results@#The 1-, 3-, 5-year survival rate was 98%, 83% and 74%, respectively. Univariate analysis demonstrated the time interval from subtotal hysterectomy (P=0.016), tumor diameter (P=0.016), clinical stage (P=0.036), histological grade (P=0.009), lymph node metastasis (P=0.044), parametrial invasion (P=0.046), myelosuppression (P=0.013) and radical surgery (P=0.019) were the poor prognostic factors of cervical stump carcinoma.@*Conclusions@#Poor prognosis of patients with cervical stump carcinoma is correlated with tumor diameter, clinical stage, histological grade, lymph node metastasis, parametrial invasion and myelosuppression. Histological grade is an independent risk factor.
