ABSTRACT

Sigmoid volvulus is a frequent cause of intestinal obstruction. Its management has evolved with the use of laparoscopic surgery, achieving an elective sigmoid resection with anastomosis after a flexible endoscopic detorsion. A female patient was admitted to the emergency room with abdominal pain, distention, and constipation. The abdominal computed tomography showed a whirled sigmoid mesentery in addition to dilated sigmoid loops, and coffee bean sign. The patient successfully underwent a flexible endoscopic detorsion and was scheduled for elective sigmoid colectomy with rectal superior artery preservation and primary anastomosis. During the sigmoid resection, the superior rectal artery preservation is related to a better prognostic, with less bleeding, anastomotic leakage, and hospital stay. Currently, there are few reports of the laparoscopic preservation of the superior rectal artery in patients with sigmoid volvulus. (AU)

ABSTRACT

We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

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

ABSTRACT Objective: Cystectomy with urinary diversion is the gold standard for muscle invasive bladder cancer. It also may be performed as part of pelvic exenteration for non-urologic malignancy, neurogenic bladder dysfunction, and chronic conditions that result in a non-functional bladder (e.g., interstitial cystitis, radiation cystitis). Our objective is to describe the surgical technique of urinary diversion using large intestine as a conduit whilst creating an end colostomy, thereby avoiding a primary bowel anastomosis and to show its applicability with respect to urologic conditions. Materials and Methods: We retrospectively reviewed five cases from a single institution that utilized the described method of urinary diversion with large intestine. We describe operative times, hospital length of stay (LOS), and describe post-operative complications. Results: Five patients with a variety of urologic and oncologic pathology underwent the described procedures. Their operative times ranged from 5 hours to 11 hours and one patient experienced a Clavien III complication. Conclusion: We describe five patients who underwent this procedure for various medical indications, and describe their outcomes, and believe dual diversion of urinary and gastrointestinal systems with colon as a urinary conduit to be an excellent surgical option for the appropriate surgical candidate.

ABSTRACT

ABSTRACT Background: The Hartmann procedure remains the treatment of choice for most surgeons for the urgent surgical treatment of perforated diverticulitis; however, it is associated with high rates of ostomy non-reversion and postoperative morbidity. Aim: To study the results after the Hartmann vs. resection with primary anastomosis, with or without ileostomy, for the treatment of perforated diverticulitis with purulent or fecal peritonitis (Hinchey grade III or IV), and to compare the advantages between the two forms of treatment. Method: Systematic search in the literature of observational and randomized articles comparing resection with primary anastomosis vs. Hartmann's procedure in the emergency treatment of perforated diverticulitis. Analyze as primary outcomes the mortality after the emergency operation and the general morbidity after it. As secondary outcomes, severe morbidity after emergency surgery, rates of non-reversion of the ostomy, general and severe morbidity after reversion. Results: There were no significant differences between surgical procedures for mortality, general morbidity and severe morbidity. However, the differences were statistically significant, favoring primary anastomosis in comparison with the Hartmann procedure in the outcome rates of stoma non-reversion, general morbidity and severe morbidity after reversion. Conclusion: Primary anastomosis is a good alternative to the Hartmann procedure, with no increase in mortality and morbidity, and with better results in the operation for intestinal transit reconstruction.


RESUMO Racional: O procedimento a Hartmann permanece sendo o tratamento de escolha da maioria dos cirurgiões para o tratamento cirúrgico de urgência da diverticulite perfurada, entretanto está associado com altas taxas de não reversão da ostomia e de morbidade pós-operatória. Objetivo: Estudar os resultados após o procedimento de Hartmann vs. ressecção com anastomose primária, com ou sem ileostomia, para o tratamento da diverticulite perfurada com peritonite purulenta ou fecal (grau de Hinchey III ou IV), e comparar as vantagens entre as duas formas de tratamento. Método: Busca sistemática na literatura de artigos observacionais e randomizados comparando ressecção com anastomose primária vs. procedimento de Hartmann no tratamento de urgência da diverticulite perfurada. Analisar como desfechos primários a mortalidade após a operação de urgência e a morbidade geral após ela; como desfechos secundários, a morbidade severa após a operação de urgência, as taxas de não reversão da ostomia, a morbidade geral e severa após a reversão. Resultados: Não houve diferenças significativas entre os procedimentos cirúrgicos para mortalidade, morbidade geral e morbidade severa. Contudo, as diferenças foram significativas estatisticamente favorecendo anastomose primária na comparação com procedimento de Hartmann nos desfechos taxas de não reversão do estoma, morbidade geral e morbidade severa após reversão. Conclusão: A anastomose primária apresenta-se como boa alternativa ao procedimento de Hartmann, sem aumento de mortalidade e morbidade, e com melhores resultados na operação de reconstrução do trânsito intestinal.

ABSTRACT

INTRODUCCIÓN: La enfermedad diverticular de colon sigmoides representa la principal causa de fistulización del colon a órganos vecinos. OBJETIVO: Describir variables clínicas y terapia quirúrgica de esta entidad. MATERIALES Y MÉTODO: Revisión retrospectiva de los casos de fístulas colónicas de origen diverticular (FCD) operados en forma electiva en un centro terciario. RESULTADOS: En un periodo de 30 años se realizó cirugía resectiva por una FCD en 49 pacientes. Los órganos más afectados fueron la vejiga en 33 casos (68%) y la vagina en 6 (12%). La cirugía efectuada fue la sigmoidectomía en 48 casos (5 con una ileostomía de protección) y una operación de Hartmann. La vía de abordaje fue laparoscópica en 4 pacientes y la morbilidad global de la serie fue 20%, sin mortalidad. Con un seguimiento promedio de 87 meses (extremos 16-178) no hubo casos de recidiva de la fístula. CONCLUSIONES: La FCD representa el 26% de los casos intervenidos por una enfermedad diverticular de colon sigmoides, lo que probablemente refleja un diagnóstico tardío. La fístula colovesical (FCV) es la fístula más común por esta causa y en la mitad de los casos tienen una presentación silenciosa. Las fístulas colovaginales ocurren en mujeres histerectomizadas. La cirugía resectiva del colon en pacientes con riesgo normal es la cirugía estándar con buenos resultados a corto y largo plazo. La cirugía laparoscópica es factible y segura especialmente en los casos de FCV.


BACKGROUND: Fistula formation is a well-known complication of diverticular disease (FCD). AIM: Determine the clinical presentation and surgical management of this kind of fistulas. MATERIALS AND METHODS: Retrospective revision of all consecutive scheduled cases operated on in a terciary public centre in a thirty-years period. RESULTS: Forty-nine patients with a segmental resection of sigmoid colon were analized. Colovesical fistulas were the most common type (n = 33), followed by colovaginal (n = 6). Resection with anastomosis was performed in 48 cases and Hartmann type operation in one. Laparoscopic procedure was made in 4 cases without conversion. Complication rate was 20% and two patients were reoperated on, without mortality in this series. Follow up showed no case of recurrence. CONCLUSIONS: FDC represent 26% of cases operated on in our series. Colovesical fistula is the most common type, followed by colovaginal fistula in histerectomized women. Resection and primary anastomosis should be the treatment of choice in average risk patients with acceptable morbidity and good long-term results. Laparoscopic approach is safe, specifically in patients with colovesical fistulas.

ABSTRACT

ABSTRACT PURPOSE: To evaluate the effects of L-lysine on the intestinal and urothelial epithelium of rats subjected to ureterosigmoidostomy (new model for surgical carcinogenesis). METHODS: Forty-two rats, 9 weeks of age, were divided into 6 groups. Animals in groups A, B, C were subjected to ureterosigmoidostomy (US) and treated with L-lysine, celecoxib and H2O, respectively. Groups D, E and F (non-operated controls) received L-lysine, celecoxib and H2O, respectively. The L-lysine dose was 150 mg/kg and that of celecoxib was 20 mg/kg. The colon was analyzed for the presence of aberrant crypt foci (ACF) under a stereomicroscope.The tissue was stained with hematoxylin and eosin and PAS alcian blue. RESULTS: There were rare ACF, and there was no statistically significant difference between the groups. Histopathologic study of the ureteral epithelium identified moderate to severe urothelial hyperplasia in rats with ureterosigmoidostomy. Transitional hyperplasia in the ureters of animals receiving L-lysine (A) showed an apparent difference compared to the control (C) (P=0.2424). There was no dysplasia or atypia CONCLUSION: L-lysine does not promote carcinogenesis of the intestinal and urethelial epithelium of rats subjected to ureterosigmoidostomy at the doses and times studied.

ABSTRACT

OBJECTIVES: This study aimed to evaluate the safety and efficacy of a new nickel-titanium shape memory alloy compression anastomosis ring, NiTi CAR 27, in constructing an anastomosis for colorectal cancer resection compared with conventional staples. METHODS: In total, 234 consecutive patients diagnosed with colorectal cancer receiving sigmoidectomy and anterior resection for end-to-end anastomosis from May 2010 to June 2012 were retrospectively analyzed. The postoperative clinical parameters, postoperative complications and 3-year overall survival in 77 patients using a NiTi CAR 27 compression ring (CAR group) and 157 patients with conventional circular staplers (STA group) were compared. RESULTS: There were no statistically significant differences between the patients in the two groups in terms of general demographics and tumor features. A clinically apparent anastomotic leak occurred in 2 patients (2.6%) in the CAR group and in 5 patients (3.2%) in the STA group (p=0.804). These eight patients received a temporary diverting ileostomy. One patient (1.3%) in the CAR group was diagnosed with anastomotic stricture through an electronic colonoscopy after 3 months postoperatively. The incidence of postoperative intestinal obstruction was comparable between the two groups (p=0.192). With a median follow-up duration of 39.6 months, the 3-year overall survival rate was 83.1% in the CAR group and 89.0% in the STA group (p=0.152). CONCLUSIONS: NiTi CAR 27 is safe and effective for colorectal end-to-end anastomosis. Its use is equivalent to that of the conventional circular staplers. This study suggests that NiTi CAR 27 may be a beneficial alternative in colorectal anastomosis in Chinese colorectal cancer patients.

ABSTRACT

ABSTRACT Objective: to evaluate the effect of L-lysine in the bladder and intestinal epithelia in rats submitted to vesicosigmoidostomy. Methods: we divided forty Wistar rats into four groups: group I - control group (Sham); group II - submitted to vesicosigmoidostomy and treated with L-lysine 150mg/kg; group III - submitted only to vesicosigmoidostomy; and group IV - received L-lysine 150mg/kg. After eight weeks the animals were sacrificed. Results: in the bladders of all operated animals we observed simple, papillary and nodular hyperplasia of transitional cells, transitional cell papillomas and squamous metaplasia. As for the occurrence of aberrant crypt foci in the colons of operated animals, we did not observe statistically significant differences in any of the distal, proximal and medium fragments, or in all fragments together (p=1.0000). Conclusion: Although statistically there was no promotion of carcinogenesis in the epithelia of rats treated with L-lysine in the observed time, it was clear the histogenesis of bladder carcinogenesis in its initial phase in all operated rats, this being probably associated with chronic infection and tiny bladder stones.


RESUMO Objetivo: o objetivo deste trabalho é avaliar o efeito da L-lisina nos epitélios vesical e intestinal de ratas submetidas à vesicossigmoidostomia. Métodos: quarenta ratas Wistar, foram divididas em quatro grupos: grupo I- grupo controle (Sham); grupo II- submetido à vesicossigmoidostomia e tratado com L-lisina 150mg/kg; grupo III- submetido apenas à vesicossigmoidostomia; e grupo IV- recebeu L-lisina 150mg/kg. Após oito semanas os animais foram sacrificados. Resultados: na bexiga de todos os animais operados observou-se hiperplasia simples, papilar e nodular de células transicionais, papiloma de células transicionais e metaplasia escamosa. Quanto à ocorrência de focos de criptas aberrantes nos colos dos animais operados, não foi evidenciado diferença estatística significante em nenhum dos fragmentos distal, proximal e médio, e todos juntos (P=1,0000). Conclusão: apesar de, estatisticamente, não ter havido promoção de carcinogênese nos epitélios dos ratos tratados com L-lisina, no tempo observado, é nítida a histogênese da carcinogênese de bexiga em sua fase inicial, no epitélio vesical, em todos os ratos operados, estando esta provavelmente associada à infecção crônica e aos diminutos cálculos vesicais.

ABSTRACT

PURPOSE: To investigate the deposition of collagen in the colon wall of patients with sigmoid diverticulitis.METHODS: Samples of sigmoid tissue from 15 patients (disease group), seven men and eight women aged 37-77 years who underwent surgery for the treatment of diverticulitis, were selected. For the control group, specimens from five patients, three men and two women aged 19-58 years undergoing emergency surgery for sigmoid trauma were selected. These subjects had no associated diseases. The histological study of the surgical specimens was performed by staining with hematoxylin-eosin and picrosirius and using a histochemical method for collagen quantification.RESULTS: Collagen deposition in the colon wall in terms of area (F), glandular epithelium (E) and total area was significantly higher in the disease group compared to control (p=0.003, p=0.026 and p=0.010, respectively). The collagen volume fraction (F fraction) and muscle tissue (M fraction) were also significantly higher compared to control (p=0.044 and p=0.026, respectively). The muscle (M area) and volume fraction of glandular epithelium (E fraction) did not differ significantly between the two groups, (p=0.074 and p=1.000, respectively).CONCLUSION: In this study, collagen deposition in the colon wall of the patients operated for sigmoid diverticulitis was higher compared to patients without the disease.

ABSTRACT

La cirugía por puerto único con técnica de guante (glove port) es un abordaje adecuado al momento económico y tecnológico que vivimos. Entre las intervenciones susceptibles de su aplicación está la realización de colostomías. Describimos la técnica quirúrgica y resultados de los pacientes a los que se realizó colostomía por puerto único con técnica de guante, a lo largo de los años 2011 y 2012, en dos hospitales de Asturias, España. Realizamos seis colostomías sigmoideas. Cuatro pacientes presentaban enfermedad tumoral, otro caso fue por una fascitis necrosante perineal, y el sexto un paciente con enfermedad de Crohn y fístulas perianales complejas. La edad media de los pacientes, cuatro hombres y dos mujeres, fue de 54 años (rango 42-67 años). El tiempo medio de intervención fue de 42 minutos (rango 30-65 minutos). No hubo complicaciones durante la cirugía ni en el postoperatorio. En nuestro medio, el gasto en material se redujo a la mitad con respecto a otros dispositivos convencionales de puerto único. La técnica de guante representa el abordaje por puerto único más económico y mínimamente invasivo para la realización de estomas, siendo en nuestra experiencia una técnica sencilla, segura y fácilmente reproducible.


The single port surgery with glove technique is a novel process, suitable to the present day economic and technological moment .Colostomies are surgical interventions suitable to its application. We describe the surgical method and outcome of patients who underwent colostomy by single port glove technique within the years 2011 and 2012, in two hospitals in Asturias, Spain. We carried out six sigmoid colostomies. Four patients had tumoral pathology, another a perineal necrotizing fasciitis, and the sixth, a patient with Crohn's disease and complex peri-anal fistulas. The average age of the patients, four men and two women, was 54 years (range 42-67 years). The average intervention time was 42 minutes (range 30-65 minutes). There were no complications during the surgery or in the postoperative period. In our facilities material expenditure was reduced to half as regards other conventional single port devices. The glove technique represents the most economic and least invasive approach for the surgical procedure of stomas, in our experience considered a simple, safe and easily reproducible technique.

ABSTRACT

Plummer-Vinson syndrome manifests as cervical dysphagia, iron deficiency anemia, an upper esophageal web, and atrophic glossitis. The cause of the esophageal web is thought to be iron deficiency anemia; however, the cause of Plummer-Vinson syndrome has not been established. Crohn's disease is usually accompanied by malnutrition and iron deficiency anemia; however, no case of concomitant Crohn's disease and Plummer-Vinson syndrome with aggravated malnutrition and anemia has been previously reported. Here, we report on a rare case of Plummer-Vinson syndrome in a Crohn's disease patient, which caused malnutrition and constipation.

ABSTRACT

The objective of this study was to compare the outcome of various surgical options for the emergency surgical management of sigmoid volvulus. This comparative study was conducted in emergency department of postgraduate medical institute Lady Reading Hospital, Peshawar over a period of one year from February 2007 to January 2008. Study comprised of hundred cases to have sigmoid volvulus on clinical and radiological grounds operated in casualty department with various surgical options and outcomes of these procedures were determined postoperatively. Out of 100 cases, 79% were males and 21% females. Majority 51% patients were in the age range of 41-60 years, 36% patients were in age group of 61-80 years. Resection and Hartman's procedure was performed in 52% cases, resection with primary anastomosis with covering colostomy in 18% cases, resection and primary anastomosis in 15% cases, and resection with double barrel colostomy [Paul Mikulicz] in 15% cases. Wound infection/ dehiscence occurred in 21% cases, intra-abdominal abscess in 9% cases, anastomosis leakage in 6% cases. Colostomy complications included bleeding in 7% cases, retraction in 7% patients, prolapse in 4% cases. Resection and Hartmann procedure was performed in majority of patients. Wound infection/dehiscence, intra-abdominal abscess, anastomosis leakage were common postoperative complications with various frequencies

ABSTRACT

Laparoscopic colorectal surgery is believed to be technically and oncologically feasible. Robotic surgery is an attractive mode in performing minimally-invasive surgery once it has several advantages if compared to standard laparoscopic surgery. The aim of this paper is to report the first known case of colorectal resection surgery using the robotic assisted surgical device in Brazil. A 35-year-old woman with deep infiltrating endometriosis with rectal involvement was referred for colorectal resection using da Vinci® surgical system. The authors also reviewed the most current series and discussed not only the safety and feasibility but also the real benefits of robotic colorectal surgery


A cirurgia laparoscópica colorretal é considerada tecnicamente factível e segura, com resultados oncológicos comparáveis à cirurgia aberta. A cirurgia robótica é uma atraente modalidade de cirurgia minimamente invasiva, com algumas vantagens claras sobre a laparoscopia convencional. O objetivo deste trabalho é descrever a experiência pioneira da cirurgia colorretal robô-assistida no Brasil. A paciente de 35 anos operada com auxílio do sistema da Vinci® tinha endometriose profunda, com envolvimento do reto. É feita ampla revisão da literatura, discutindo não apenas a indicação e segurança da cirurgia robótica colorretal, mas também seus reais benefícios
