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.

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.

Does laparoscopic reoperation yield symptomatic improvements similar to those of primary laparoscopic Heller myotomy in achalasia patients?

BACKGROUND: Laparoscopic Heller myotomy fails in approximately 3.5% to 15% of patients. Evidence of successful laparoscopic reoperation is limited to a few studies. METHODS: This case-control study was conducted in patients who underwent laparoscopic Heller myotomy reoperation (LHM-R) from 2008 to 2016. The operative outcomes, preoperative and last follow-up manometric parameters, and symptom questionnaire results, including the Eckardt, Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) and eating assessment tool (EAT-10) scores, were obtained. The data were compared with those of patients who underwent primary laparoscopic Heller myotomy (LHM-1). RESULTS: Thirty-five patients who underwent LHM-R and 35 patients who underwent LHM-1 were included. The reasons for failure in the LHM-R patient group included incomplete myotomy (71.4%), myotomy fibrosis (25.7%) and structural alterations in fundoplication (2.9%). The follow-up duration was 34 months for the LHM-R group and 24 months for the LHM-1 group (p = 0.557). The procedure was performed by laparoscopy in 100% of the patients in the two groups. No differences were found regarding surgical morbidity (11.4% LHM-R vs. 2.9% LHM-1, p = 0.164). The symptomatic outcomes were equivalent between groups (Eckardt p = 0.063, EAT-10 p = 0.166, GERD-HRQL p = 0.075). An IRP < 15 mmHg was achieved in 100% of the LHM-R and LHM-1 patients. At the last follow-up, 82.1% of the LHM-R patients and 91.4% of the LHM-1 patients were in symptomatic remission (p = 0.271). CONCLUSION: The results achieved with LHM-R are similar to those achieved with LHM-1. Laparoscopic reoperation should be considered an effective and safe treatment after a failed Heller myotomy.

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.

Clinical characteristics and surgical treatment of schwannomas of the esophagus and stomach: A case series and systematic review.

BACKGROUND: Gastrointestinal schwannomas are slow-growing benign mesenchymal neoplasms that originate from Schwann cells of the nerve sheath of Auerbach´s plexus or less frequently from Meissner´s plexus. The main differential diagnosis of gastric schwannomas are the gastrointestinal stromal tumors (GISTs), which are classified by their immunohistochemistry. The treatment of choice for gastric schwannomas is surgery where laparoscopy plays an important role. Wedge resection, subtotal or total gastrectomy can be done. In its counterpart, esophageal schwannomas are benign tumors of the esophagus that are very uncommon since they comprise less than 2% of all esophageal tumors. The main differential diagnosis is the leiomyoma which corresponds to the most common benign esophageal tumor, followed by GIST. The treatment consists on tumoral enucleation or esophagectomy. AIM: To review the available literature about gastrointestinal schwannomas; especially lesions from de stomach and esophagus, including diagnosis, treatment, and follow up, as well as, reporting our institutional experience. METHODS: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guidelines. The following databases were used for reviewing process: PubMed, Ovid, MEDLINE, and Scopus. Only English language manuscripts were included. All gastrointestinal schwannomas specifically located in the esophagus and stomach were included. Cases that did not report long-term follow-up were excluded. RESULTS: Gastric localization showed a higher prevalence in both, the literature review and our institution: 94.95% (n = 317) and 83% (n = 5) respectively. With a follow-up with disease-free survival greater than 36 mo in most cases: 62.01% (n = 80) vs 66.66% (n = 4). In both groups, the median size was > 4.1 cm. Surgical treatment is curative in most cases. CONCLUSION: Schwannoma must be taken into account in the differential diagnosis of gastrointestinal mesenchymal tumors. It has a good prognosis, and most are benign. A disease-free survival of more than 36 mo can be achieved by surgery.

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.

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.

Mujer joven con hepatocarcinoma fibrolamelar metastásico; citorreducción y HIPEC: a propósito de un caso / Young woman with metastatic fibrolamellar hepatocarcinoma; cytoreductive surgery and HIPEC: a case report

Objetivo: Reportar un caso clínico de hepatocarcinoma fibrolamelar metastásico y su manejo multidisciplinario. Caso clínico: Paciente de 24 años de edad con dolor abdominal, distensión abdominal y fiebre. Se le realizó tomografía computarizada de abdomen donde se encontró tumoración hepática irregular. Se realizó laparotomía con evidencia de múltiples implantes en cavidad abdominal y se diagnosticó mediante estudio histopatológico hepatocarcinoma fibrolamelar metastásico. Se decidió realizar citorreducción más quimioterapia hipertérmica intraperitoneal (HIPEC). La sobrevida de la paciente fue de 11 meses. Discusión: El hepatocarcinoma fibrolamelar es un tumor raro. Aún no hay consenso sobre el mejor tratamiento en pacientes con metástasis que tengan buena funcionalidad. El manejo actual se basa en la quimioterapia sistémica y la resección quirúrgica en casos localizados. En el caso de nuestra paciente, la cirugía citorreductora más HIPEC se realizó con la intención de mejorar la supervivencia. Se necesita más evidencia para definir esta estrategia como tratamiento estándar.

Aim: To report a clinical case of metastatic fibrolamellar hepatocarcinoma and its multidisciplinary management. Case report: 24 year-old patient with abdominal pain, bloating and fever. A computed tomography of the abdomen was performed; an irregular hepatic tumor was found. A laparotomy was performed with evidence of multiple implants in the abdominal cavity and the histopathology report was metastatic fibrolamellar hepatocarcinoma. It was decided to perform cytoreductive surgery plus HIPEC. The patient's survival was 11 months. Discussion: Fibrolamellar hepatocarcinoma is a rare tumor. There is still no consensus on the treatment of choice in patients with metastases with good functionality status. Current management is based on systemic chemotherapy and surgical resection in localized cases. In the case of our patient, cytoreductive surgery plus HIPEC was performed with the intention of improving survival. More evidence is needed to define this strategy as standard treatment.
