Metastatic clear-cell renal carcinoma: an exceptional cause of ileocolonic intussusception in adults

Introduction: Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration. Case Presentation: A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception. Discussion: Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause.

Deloyers procedure compared to ileorectal anastomosis as restoration techniques of bowel continuity after extended left colon resection.

BACKGROUND: Restoration of bowel continuity after left extended colectomy may be challenging because the remaining colon may not reach the rectal stump without tension to perform a safe anastomosis. Performing a total colectomy with ileorectal anastomosis (IRA) is an option, but the quality of life can be significantly impaired due to loose stools and an increase in bowel frequency. In contrast, the preservation of the right colon and ileocaecal valve in the Deloyers procedure (DP) might ensure a better stool consistency and bowel transit, and therefore a superior quality of life. MATERIALS AND METHODS: A transverse study comparing patients that underwent DP versus patients with an IRA was performed. Postoperative morbidity, mortality, functional outcomes, and quality of life were analysed between groups. Quality of life after the surgical procedure was assessed with the SF-36 V2® health survey. RESULTS: A total of 16 patients with DP and 32 with IRA were included. The groups had similar demographic characteristics concerning age, sex, body mass index, ASA classification, diagnosis and Charlson comorbidity index. The median follow-up was 55 months for DP and 99 months for IRA. Postoperative complications were similar in both groups. Patients in the DP group had fewer bowel movements (P = 0.01), tenesmus (P = 0.04) and use of loperamide (P = 0.03). DP patients achieved better scores in physical pain (P = 0.02) and general health (P < 0.01) than IRA patients. CONCLUSIONS: DP for intestinal continuity restoration after extended left colon resection is a safe and feasible alternative, possibly achieving better functional outcomes and quality-of-life compared to IRA.

LAW Trial - The Impact of Local Anesthetics Infiltration in Surgical Wound for Gastrointestinal Procedures (LAW): A Double-Blind, Randomized Controlled Trial.

INTRODUCTION AND AIMS: Prior studies have suggested that infiltration of local anesthetics reduce the rate of surgical site infections (SSIs). Opioid usage has become an epidemic. Some analgesic modalities, such as epidural analgesia and transversus abdominis plane block are associated with shorter length of stay and lower opioid use. The aim of our study was to assess the relationship between local infiltration of bupivacaine with rates of SSI and pain control. MATERIALS AND METHODS: We conducted a prospective, double-blinded randomized controlled trial in patients who underwent open major gastrointestinal procedures from July 2016 to June 2017. Patients were divided into two groups based on administration of 0.5% bupivacaine (n = 30) (group 1) or placebo (n = 30) (control group). Outcomes evaluated were SSI, postoperative opioid requirements and pain scores. RESULTS: Patients in the bupivacaine group required a lower dose of epidural analgesia during the first 24 h (5.3 mcg/kg/h vs. 6.4 mcg/kg/h; p = 0.05). Opioid requirement was shorter in the bupivacaine group (3.5 ± 2.3 days vs. 5.7 ± 2.9 days; p = 0.01). No difference was found between groups in terms of SSI rates (0% vs. 6.7%, p = 0.49). CONCLUSIONS: There is no clear association between bupivacaine infiltration and reduction of SSI rate according to our study. Wound bupivacaine infiltration is associated with a lower dose of epidural infusion and opioid requirements.

The Educational Quality of Laparoscopic Right Hemicolectomy Videos on YouTube.

Introduction. Surgical technique videos are an important part of surgical fellows' education. YouTube has been identified as the preferred source of educational videos among trainees. The aim of this article is to objectively evaluate the quality of the 50 most viewed videos on YouTube concerning right laparoscopic hemicolectomy using LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS). We hypothesized that the number of likes or views will not necessarily reciprocate with the educational content. Materials and methods. This observational study started with a YouTube search under the words "laparoscopic right hemicolectomy", "right colectomy", and "right hemicolectomy". The 50 most viewed videos with an English title were chosen. Video characteristics and LAP-VEGaS score were analyzed by four colorectal surgery fellows from a tertiary center in Mexico City. Results. Right hemicolectomy videos were reviewed; there was no correlation between the LAP-VEGaS score and the view ratio, the like ratio, or the video power index. The LAP-VEGaS score was significantly higher among videos uploaded by medical associations, journals, or commercial when compared with videos uploaded by doctors/physicians or academic associations. Conclusion. Educational quality in right laparoscopic hemicolectomy videos did not reciprocate with their educational quality, but it agrees significantly with the video uploading source. Low educational quality was identified among the videos underscoring the need to endorse peer-reviewed video channels.

Colonic lipomas an uncommon cause of intussusception in adult patients: report of three cases and literature review.

Colonic lipomas are infrequent, benign, non-epithelial, fatty neoplasms. Most of the colonic lipomas are asymptomatic, but around 25% of patients may develop symptoms. Nowadays, surgical resection of the involved segment is the treatment of choice. We report three cases of colonic intussusceptions caused by colonic lipomas in adult patients. The patients underwent surgical resection, and the diagnosis was confirmed by histopathological examination of the specimens.

Los lipomas colónicos son neoplasias benignas, adiposas, no epiteliales poco frecuentes. La mayoría de los lipomas de colon son asintomáticos, pero alrededor del 25% de los pacientes pueden desarrollar síntomas. En la actualidad, la resección quirúrgica del segmento afectado es el tratamiento de elección. Presentamos tres casos de intususcepción intestinal secundaria a lipomas colónicos en pacientes adultos. Los pacientes fueron sometidos a resección quirúrgica y el diagnóstico se confirmó mediante examen histopatológico.

Influence of Muscle Mass Area and Visceral Obesity on 30-day Mortality After Colorectal Surgery with Primary Anastomosis.

BACKGROUND: Muscle mass and visceral fat may be assessed at the level of the third lumbar vertebra (L3) in computed tomography (CT). Both variables have been related with adverse surgical outcomes. OBJECTIVE: The objective of the study was to study the association of skeletal muscle index (SMI) and visceral fat area (VFA) with 30-day mortality in colorectal surgery. METHODS: This is a retrospective cohort study conducted at a tertiary referral hospital in Mexico City. Patients who underwent colorectal surgery with primary anastomosis from January 2007 to December 2018 were included in the study. Their preoperative CT scans were analyzed with the NIH ImageJ software at the level of the third lumbar vertebra to determine their SMI (L3-SMI) and the VFA. Logistic regression analysis (adjusted by surgery anatomical location) was used to determine the association between these variables and surgical 30-day mortality. RESULTS: A total of 548 patients were included; 30-day mortality was 4.18% (23 patients). On univariable analysis, L3-SMI, low SMI, anastomosis leak, pre-operative albumin, estimated blood loss, age, steroid use, Charlson comorbidity index score >2, and type of surgery were associated with 30-day mortality. On multivariable analysis, low SMI remained an independent risk factor with an odds ratio of 4.74, 95% confidence interval 1.22-18.36 (p = 0.02). CONCLUSION: Low SMI was found to be an independent risk factor for 30-day mortality in patients submitted to colorectal surgery with a primary anastomosis, whether for benign or malignant diagnosis. VFA was not associated with 30-day mortality.

Sociodemographic factors related with emergency colorectal cancer surgery at a referral center in Mexico.

BACKGROUND: Diagnosis of colorectal cancer (CRC) after emergency presentation is associated with a worse prognosis. AIM: The aim of the study was to determine the sociodemographic factors related with emergency CRC surgery at our institution. METHODS: From January 2009 to December 2017, patients that underwent CRC surgery at our institution were included in the study. Univariate and multivariate logistic regression were used to determine the effect of the potential risk factors on the rate of emergency surgery. RESULTS: A total of 247 patients underwent CRC surgery at our institution. The rate of emergency surgery was 7.7%. On univariate analysis, patients without a family history of cancer (odds ratio [OR]: 4.95), living in a rural area (OR: 3.7), and late clinical cancer stage (OR: 5.06) were associated with emergent surgery. Mid-income status was a protective factor for emergency surgery (OR: 0.14, p = 0.003). On multivariate analysis, late clinical cancer stage (OR: 4.41, 95% CI 1.21-16.05, p = 0.024) and mid-income economic status (OR: 0.41, 95% CI 0.04-0.55, p = 0.004) were identified as independent risk factors for emergency surgery. CONCLUSION: Social, economic, and demographic factors were identified as predictors for emergent CRC surgery.

ANTECEDENTES: El diagnóstico de cáncer colorrectal (CCR) en el contexto de urgencia está asociado a un mal pronóstico. OBJETIVO: Determinar los factores sociodemográficos asociados a cirugía de urgencia en el CCR en nuestra institución. MÉTODO: De enero de 2009 a diciembre de 2017 se incluyeron los pacientes operados de CCR y se realizaron análisis univariado y multivariado para determinar los potenciales factores de riesgo. RESULTADOS: Se incluyeron en el estudio 247 pacientes operados de CCR. El 7.7% de las cirugías fueron de urgencia. En el análisis univariado, los pacientes sin antecedentes familiares de cáncer (odds ratio [OR]: 4.95), los habitantes de zonas rurales (OR: 3.7) y aquellos en etapas avanzadas del cáncer (OR: 5.06) se asociaron a cirugía de urgencia. Los pacientes con nivel socioeconómico medio tuvieron menos probabilidad de que su cirugía fuera de urgencia (OR: 0.14; p = 0.003). En el análisis multivariado, debutar con una etapa clínica avanzada (OR: 4.41; intervalo de confianza del 95% [IC95%]: 1.21-16.05; p = 0.024) y tener un nivel socioeconómico medio (OR: 0.41; IC95%: 0.04-0.55; p = 0.004) fueron factores independientes para cirugía de urgencia por CCR. CONCLUSIONES: Los factores sociales, económicos y demográficos se encontraron relacionados con la necesidad de cirugía de urgencia por CCR.

A systematic review and meta-analysis of diverting loop ileostomy versus total abdominal colectomy for the treatment of Clostridium difficile colitis.

BACKGROUND: Clostridium difficile is an increasingly common source of in-patient morbidity and mortality. We aim to assess the effects of diverting loop ileostomy (DLI) versus total abdominal colectomy (TAC) for Clostridium difficile colitis (CDC), in terms of mortality and morbidity. METHODS: Systematic literature search was performed using PubMed, Embase, Cochrane, and Web of Science databases for randomized and non-randomized studies comparing DLI and TAC for fulminant CDC. Meta-analysis was carried out for mortality and postoperative complications. RESULTS: Five non-randomized studies qualified for inclusion in the quantitative synthesis. In total, 3683 patients were allocated to DLI (n = 733) or TAC (n = 2950). The overall mortality was equivalent (OR 0.73; 95% CI 0.45-1.20; P = 0.22). Regarding secondary outcomes, the pooled analysis revealed the following equivalent rates of postoperative events: thromboembolism (OR 0.45; 95% CI 0.14-1.43; P = 0.18), acute renal failure (OR 1.71; 95% CI 0.91-3.23; P = 0.10), surgical site infection (OR 0.95; 95% CI 0.11-8.59; P = 0.97), pneumonia (OR 0.98; 95% CI 0.36-2.66; P = 0.97), urinary tract infection (OR 0.81; 95% CI 0.26-2.52; P = 0.72), and reoperation (OR 0.95; 95% CI 0.50-1.82; P = 0.78). The ostomy reversal rate was significantly higher in DLI (OR 12.55; 95% CI 3.31-47.55; P = 0.0002). CONCLUSIONS: The overall morbidity and mortality rates between DLI and TAC for the treatment of CDC seemed to be equivalent. Evidence from a randomized controlled trial is needed to clarify the timing and understand the impact of DLI for CDC.

Sarcopenia in patients with colorectal cancer: A comprehensive review.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer globally and the second cancer in terms of mortality. The prevalence of sarcopenia in patients with CRC ranges between 12%-60%. Sarcopenia comes from the Greek "sarx" for flesh, and "penia" for loss. Sarcopenia is considered a phenomenon of the aging process and precedes the onset of frailty (primary sarcopenia), but sarcopenia may also result from pathogenic mechanisms and that disorder is termed secondary sarcopenia. Sarcopenia diagnosis is confirmed by the presence of low muscle quantity or quality. Three parameters need to be measured: muscle strength, muscle quantity and physical performance. The standard method to evaluate muscle mass is by analyzing the tomographic total cross-sectional area of all muscle groups at the level of lumbar 3rd vertebra. Sarcopenia may negatively impact on the postoperative outcomes of patients with colorectal cancer undergoing surgical resection. It has been described an association between sarcopenia and numerous poor short-term CRC outcomes like increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care and physical disability. Sarcopenia may also negatively impact on overall survival, disease-free survival, recurrence-free survival, and cancer-specific survival in patients with non-metastatic and metastatic colorectal cancer. Furthermore, patients with sarcopenia seem prone to toxic effects during chemotherapy, requiring dose deescalations or treatment delays, which seems to reduce treatment efficacy. A multimodal approach including nutritional support (dietary intake, high energy, high protein, and omega-3 fatty acids), exercise programs and anabolic-orexigenic agents (ghrelin, anamorelin), could contribute to muscle mass preservation. Addition of sarcopenia screening to the established clinical-pathological scores for patients undergoing oncological treatment (chemotherapy, radiotherapy or surgery) seems to be the next step for the best of care of CRC patients.

Predictors of dehydration and acute renal failure in patients with diverting loop ileostomy creation after colorectal surgery.

BACKGROUND: Despite the potential benefits of fecal diversion after low pelvic anastomosis in colorectal surgery, diverting loop ileostomy construction is related to significant rates of complications. AIM: To determine potential predictors of high output related complications in patients with diverting loop ileostomy creation after colorectal surgery. METHODS: Patients who underwent open and laparoscopic colorectal surgery requiring a diverting loop ileostomy from January 2010 to March 2018 were retrospectively analyzed. We included patients older than 18 years, who underwent colorectal surgery with primary low pelvic anastomosis, and with the creation of a diverting loop ileostomy, at elective or emergency settings for the treatment of benign or malignant conditions. Univariate and multivariate logistic regression analysis was used to determine the effect of the potential predictors on the rate of high output related complications. The high output related complications were dehydration and acute renal failure that required visits to the emergency department and hospitalizations. RESULTS: Of the 102 patients included in the study, 23.5% (n = 24) suffered high output related complications. In this group of patients at least one visit to the emergency department (mean 1.6), and at least one readmission to the hospital was needed. The factors associated with high-output ileostomy, in the univariate analysis, were: urgent surgical intervention (OR = 2.6; P = 0.047), the development of postoperative complications (OR = 3; P = 0.024), have ulcerative colitis (OR = 4.8; P = 0.017), use of steroids (OR = 4.3; P = 0.010), mean output at discharge greater than 1000 mL/24 h (OR = 3.2; P = 0.016), and use of loperamide at discharge (OR = 2.8; P = 0.032). Multivariate logistic regression analysis identified two independent risk factors for high output related complications: ulcerative colitis [OR = 7.6 (95%CI: 1.81-31.95); P = 0.006], and ileostomy output at discharge ≥ 1000 mL/24 h [OR = 3.3 (1.18-9.37); P = 0.023]. CONCLUSION: In our study, patients with ulcerative colitis and those with an ileostomy output above 1000 mL/24 h at discharge, were at increased risk of high output related complications.

Signet ring cell carcinoma of the rectum: atypical metastatic presentation.

Colorectal cancer is the third most common cancer in the world and the fourth most common cause of death related to cancer. Signet ring cell carcinoma represents an uncommon histological type for rectal cancer with less than 1% of all rectal neoplasms. It usually behaves aggressively and has an inferior prognosis. We present the case of a young man diagnosed with signet ring cell rectal carcinoma. He underwent neoadjuvant therapy with partial response, had surgery with curative intent and showed local recurrence after only 3 months. Disease progression happened only weeks after recurrence with metastasis to vertebrae, extraocular muscles, bone marrow and skin. He is currently receiving palliative chemotherapy.

Multivariate analysis of risk factors for complications after loop ileostomy closure.

BACKGROUND: Despite the advantages of diverting loop ileostomy construction, it is related to complications. OBJECTIVE: The aim of the study was to determine the risk factors for complications after loop ileostomy closure. METHODS: Patients who underwent loop ileostomy closure from January 2010 to March 2018 were retrospectively analyzed. Multivariate logistic regression was used to determine the effect of the potential risk factors on the rate of each complication. RESULTS: A total of 136 patients underwent reversal. Indications for the initial operation were colorectal cancer (39.7%), diverticulitis (25.7%), idiopathic chronic ulcerative colitis (ICUC) (8.1%), familial adenomatous polyposis (FAP) (7.4%), and others (19.1%). Multivariate analysis identified the following risk factors: type of incision (midline laparotomy) (odds ratio [OR] = 6.5) for wound infection; treatment with immunomodulator (OR = 12.5) for anastomotic leak; history of FAP (OR = 9.8) for intestinal obstruction; previous use of immunomodulator (OR = 10.0) and performing reversal through midline incision (OR = 18.9) for reoperation; and ≥ 65 years old (OR = 3.5) for medical complications. The rate of incisional hernia was 11%, and the risk factors were time to closure < 3 months (OR = 6.4) and parastomal hernia (OR = 13.2). CONCLUSIONS: Several patient-related and surgical technique factors should be considered at the time of loop ileostomy closure to reduce post-operative morbidity.

ANTECEDENTES: A pesar de las ventajas de la ileostomía en asa de derivación, múltiples complicaciones se han asociado a su uso. OBJETIVO: Determinar los factores de riesgo para presentar complicaciones tras el cierre de una ileostomía en asa. MÉTODO: Se realizó un análisis retrospectivo de los pacientes sometidos a cierre de ileostomía en asa de enero de 2010 a marzo de 2018. Se determinaron los factores de riesgo utilizando regresión multivariable. RESULTADOS: Se incluyeron 136 pacientes. Las indicaciones para cirugía fueron cáncer colorrectal (39.7%), diverticulitis (25.7%), colitis ulcerosa crónica idiopática (CUCI) (8.1%), poliposis adenomatosa familiar (PAF) (7.4%) y otras (19.1%). Se identificaron los siguientes factores de riesgo: incisión en línea media (OR: 6.5) para infección de herida; tratamiento inmunomodulador (OR: 12.5) para fuga de anastomosis; antecedente de PAF (OR: 9.8) para oclusión intestinal; tratamiento inmunomodulador (OR: 10) e incisión en línea media (OR: 18.9) para reintervención; y edad ≥ 65 años (OR: 3.5) para complicaciones médicas. La frecuencia de hernia incisional fue del 11%: < 3 meses para el cierre (OR: 6.4) y hernia parastomal (OR: 13.2). CONCLUSIONES: Numerosos factores relacionados con el paciente y con la técnica quirúrgica deben de ser considerados al momento del cierre de la ileostomía en asa para reducir la morbilidad posoperatoria.

Factors associated with emergent colectomy in patients with neutropenic enterocolitis.

PURPOSE: Neutropenic enterocolitis (NEC) is a severe complication of neutropenia. NEC is characterized by segmental ulceration, intramural inflammation, and necrosis. Factors present in patients who underwent colectomy have never been studied. The present study aimed to describe the clinical factors present in patients who underwent emergent colectomy for the treatment of neutropenic enterocolitis. METHODS: Patients admitted with neutropenic enterocolitis from November 2009 to May 2018 were retrospectively analyzed. Logistic regression analysis was used to determine clinical factors associated with emergent colectomy. RESULTS: Thirty-nine patients with NEC were identified. All patients had a hematological disorder. Medical treatment was the only management in 30 (76.9%) patients, and 9 (23.1%) patients underwent colectomy. No differences were found between the treatment groups regarding sex, age, or comorbidities. Patients were more likely to undergo colectomy if they developed abdominal distention (OR = 12, p = 0.027), hemodynamic failure (OR = 6, p = 0.042), respiratory failure (OR = 17.5, p = 0.002), multi-organic failure (OR = 9.6, p = 0.012), and if they required ICU admission (OR = 11.5, p = 0.007). Respiratory failure was the only independent risk factor for colectomy in multivariable analysis. In-hospital mortality for the medical and surgical treatment groups was 13.3% (n = 4) and 44.4% (n = 4), respectively (p = 0.043). CONCLUSIONS: In our study, most NEC patients were treated conservatively. Patients were more likely to undergo colectomy if they developed organ failures or required ICU admission. Early surgical consultation is suggested in all patients with NEC.

Oncological Implications of Lymph Nodes Retrieval and Perineural Invasion in Colorectal Cancer: Outcomes from a Referral Center.

BACKGROUND: In colorectal cancer (CRC), regional lymphadenectomy provides prognostic information and guides management. The current consensus states that at least 12 lymph nodes (LN) should be evaluated. The aims of this study were to identify whether the number of LN is a predictor for survival and recurrence, and to reveal the role of LN ratio (LNR) and perineural invasion (PNI) in predicting prognosis after curative resection of CRC. METHODS: We included all patients who underwent surgery for CRC between 2000 and 2016 in an academic medical center in Mexico. The LNR cutoff value was 0.25. We analyzed two groups according to the number of LN retrieved: Group 1 (≥ 12 LN) and Group 2 (< 12 LN). RESULTS: We included 305 patients, 13.8% in Stage I, 45.6% in Stage II, and 40.6% in Stage III. The male: female ratio was 1.1. The mean age was 62.6 ± 14 years (range, 19-92). In 233 patients (76.4%), ≥ 12 LN were obtained. Recurrence rates in Groups 1 and 2 were 20.2% versus 26.4%, respectively (p = 0.16). PNI was present in 34 patients (13.2%). An LN harvest < 10 increased local and distant recurrences (p = 0.03). Stage III patients with an LNR ≥ 0.25 had higher overall recurrence rates (p = 0.012) and mortality (p = 0.029). In a multivariate Cox regression analysis, PNI-negative tumors were an independent prognostic factor for disease-free survival (p = 0.011, hazard ratio = 2.78, 95% confidence interval = 1.26-6.16). CONCLUSIONS: An LN retrieval < 10 increased local and distant recurrence rates. LNR was an independent prognostic factor for survival in Stage III tumors. PNI was the only significant independent prognostic factor affecting disease-free survival in our patients.

Postoperative outcomes and functional results after Deloyer's procedure - a retrospective cohort study / Desfechos pós-operatórios e resultados funcionais após o procedimento de Deloyer ­ um estudo de coorte retrospectivo

ABSTRACT Introduction: The objective of our study was to describe surgical outcomes of Deloyers procedure in our referral center, and to compare the results of patients with and without protective ileostomy. Methods: Patients undergoing a Deloyers procedure from 2013 to 2016 were prospectively included. General characteristics, intraoperative variables, postoperative course, and functional outcomes were analyzed. Patients were compared into two groups: group (1) patients undergoing Deloyers procedure without ileostomy, and group (2) Deloyers procedure with protective ileostomy. Results: Sixteen patients undergoing isoperistaltic transposition of the right colon remnant were included, of which 9 (63%) were males with a median age of 47 (range 22-76) years. The main surgical indication was the restoration of bowel transit (62.5%). There was higher major morbidity rate in the Deloyers procedure with protective ileostomy group, but without statistical significance (20% vs. 9%, p = 0.92). No leaks or deaths were reported. The length of hospital stay was 7 days. The mean number of bowel movements per day was 4 at 18 months of follow up. Only four (25%) patients used irregularly loperamide. Conclusions: The Deloyers procedure has satisfactory results and is reproducible with low morbidity. The major and minor morbidity rates were similar between groups, suggesting that the costs and risks of a second procedure can be avoided by providing a safe primary anastomosis.

RESUMO Introdução: O objetivo de nosso estudo foi descrever os resultados cirúrgicos do procedimento de Deloyer em nosso centro de referência e comparar os resultados de pacientes com e sem ileostomia de proteção. Métodos: Pacientes submetidos ao procedimento de Deloyer de 2013 a 2016 foram incluídos prospectivamente. Foram analisadas as características gerais, as variáveis intraoperatórias, o curso pós-operatório e os desfechos funcionais. Os pacientes foram comparados em dois grupos: Grupo 1) pacientes submetidos ao procedimento de Deloyer (PD) sem ileostomia, e grupo 2) procedimento de Deloyer com ileostomia de proteção (IP). Resultados: Foram incluídos 16 pacientes submetidos à transposição isoperistáltica da porção remanescente do cólon direito, dos quais 9 (63%) eram do sexo masculino com idade média de 47 anos (variação de 22-76) anos. A principal indicação cirúrgica foi a restauração do trânsito intestinal (62,5%). Houve maior morbidade maior no grupo IP, mas sem significância estatística (20% vs. 9%, p = 0,92). Nenhum vazamento ou óbito foi relatado. A duração da hospitalização foi de 7 dias. O número médio de evacuações por dia foi 4, aos 18 meses de seguimento. Apenas quatro (25%) pacientes utilizaram irregularmente a loperamida. Conclusões: O procedimento de Deloyer tem resultados satisfatórios e é reprodutível com baixa morbidade. As taxas de morbidades maiores e menores foram semelhantes entre os grupos, sugerindo que os custos e riscos de um segundo procedimento podem ser evitados proporcionando-se uma anastomose primária segura.

Usefulness of Gum Chewing to Decrease Postoperative Ileus in Colorectal Surgery with Primary Anastomosis: A Randomized Controlled Trial.

BACKGROUND: Postoperative ileus generates a high impact on morbidity, hospital stay, and costs. OBJECTIVE: To study the efficiency and safety of chewing gum to decrease postoperative ileus in colorectal surgery. METHOD: A randomized controlled trial was performed including 64 patients who underwent elective colorectal surgery with primary anastomosis in a tertiary referral center. Patients were divided in two groups: (i) A: gum chewing group (n = 32), and (ii) B: patients who had standard postoperative recovery (n = 32). RESULTS: Postoperative ileus was observed in 6% (2/32) of the gum-chewing group and in 21.8% (7/32) in the standard postoperative recovery group, with an odds ratio of 0.167 (95% CI: 0.37-0.75; p = 0.006). Vomiting was present in two patients from group A and in eight from group B (6.25 vs. 25.0%; p = 0.03). Passage of flatus within the first 48 hours was present in 30 patients from group A and in 20 from group B (94 vs. 63%; p = 0.002). There was earlier oral feeding (96 ± 53 vs. 117 ± 65 hours; p= 0.164) and a shorter length of hospital stay (7 ± 5 vs. 9 ± 5 days; p= 0.26) in the gum-chewing group (p N.S.). CONCLUSIONS: The use of chewing gum after colorectal surgery was associated with less postoperative ileus and vomiting, and with an increased passage of flatus within the first 48 hours after surgery. Since gum chewing is an inexpensive procedure and is not associated with higher morbidity, it can be safely used for a faster postoperative recovery in elective colorectal surgery.

Advantages of Minimally Invasive Surgery for the Treatment of Colovesical Fistula.

BACKGROUND: Colovesical fistulas in two-thirds of the cases are due to diverticular disease. In recent years, a minimally invasive approach has shown advantages over the traditional open approach. The goal of this study was to evaluate the surgical results and safety of the laparoscopic procedure in patients with colovesical fistula. MATERIAL AND METHODS: We retrospectively evaluated 24 patients who underwent surgery for colovesical fistula in a referral center from 2005 to 2011. Patients were divided into two groups: (i) laparoscopic approach, and (ii) open approach. RESULTS: The laparoscopic and open groups had similar characteristics with respect to age and gender distribution. There were a higher number of bladder repairs in the open approach group (83.3 vs. 16.6%; p = 0.01). The operative time (212 ± 74 min vs. 243 ± 69 min; p = 0.313) and intraoperative bleeding (268 ± 222 ml vs. 327 ± 169 ml; p = 0.465) were similar in both groups. The conversion rate of the laparoscopic approach to open surgery was 25%. There was no difference in morbidity (41.1 vs. 25%; p = 0.414), although the laparoscopic group had a shorter hospital stay (9 ± 4 days vs. 15 ± 11 days; p = 0.083) without statistical significance. CONCLUSIONS: The treatment of colovesical fistula by a laparoscopic approach is safe and is associated with less bladder repairs and a shorter hospital stay.
