Análisis de variables relacionadas con la morbimortalidad de la anastomosis ileocólica después de hemicolectomía derecha / Analysis of variables related to morbidity and mortality of the ileocolic anastomosis after right hemicolectomy

Introducción: La hemicolectomía derecha con anastomosis ileocólica es una cirugía frecuentemente realizada para la que existen muchas formas de realizarla. Objetivo: Evaluar cuál es la mejor anastomosis ilecólica en términos de morbimortalidad y realizar una evaluación comparativa de la evolución clínica posoperatoria según el tipo de configuración anastomótica. Pacientes y Método: Estudio observacional analítico, con criterios de inclusión y exclusión definidos. Las variables a estudiar las dividimos en dos grupos, las relacionadas a la técnica quirúrgica y su configuración anastomótica, y las variables relacionadas con resultados de la intervención quirúrgica, creando una tabla de contingencia en que se cruzan los datos. Análisis de datos con STATA 13.0. Resultados: 216 pacientes con anastomosis ileocólica, destacando significancia estadística al cruzar: A) reoperación y tipo de sutura (p = 0,044), con un OR 3,4 (IC 95% 0,94-18,6), siendo de mayor riesgo la mecánica; B) mortalidad y urgencia (p = 0,001) con un OR 7,76 (IC 95% 1,56-49,29), siendo de mayor riesgo la cirugía de urgencia. Las anastomosis isoperistálticas possen eliminación de gases (p < 0,001), tránsito intestinal (p = 0,009) e ingesta de sólidos (p = 0,005) más precoz. Hay expulsión de gases antes en el abordaje laparoscópico, sutura manual, configuración término lateral e isoperistáltica de la anastomosis y cirugía electiva. Conclusión: Existe gran variabilidad de técnicas para realizar la anastomosis ileocólica. La anastomosis manual muestra menor probabilidad de necesitar una reintervención quirúrgica, la cirugía electiva tiene menor mortalidad que la realizada de urgencia. Sugerimos realizarla vía laparoscópica, con sutura manual, término lateral, isoperistáltica y de forma electiva, por tener una recuperación más corta.

Introduction: Right hemicolectomy with ileocolic anastomosis is a frequent surgery with many ways to perform it. Objective: To evaluate which is the best ileocolic anastomosis in terms of morbidity and mortality and to make a comparative evaluation of the postoperative clinical evolution according to the type of anastomosis. Patients and Method: Analytical observational study, with defined inclusion and exclusion criteria. The variables to be studied are divided into two groups, those related to the surgical technique and its anastomotic configuration, and the variables related to the results of the surgical intervention, creating a contingency table that crosses the data. Data analysis with STATA 13.0. Results: 216 patients with ileocolic anastomosis, highlighting statistical significance when crossing: A) reoperation and type of suture (p = 0.044), with UN or 3.4 (95% CI 0.94 to 18.6), being of greater risk the mechanics; B) mortality and urgency (p = 0.001) with an OR 7.76 (95% CI 1.56-49.29), with emergency surgery being of greater risk. Isoperistaltic anastomosis with gas elimination (p < 0.001), intestinal transit (p = 0.009) and solid intake (p = 0.005) earlier. There is earlier expulsion of gases in the laparoscopic approach, manual suture, end-to-side and isoperistaltic of the anastomosis and elective surgery. Conclusion: There is great variability of techniques to perform the ileocolic anastomosis. Manual anastomosis is less likely to require surgical reoperation, elective surgery has a lower mortality than that of emergency surgery. We suggest performing it laparoscopically, with manual suture, lateral term, isoperistaltic and electively, for having a shorter recovery.

Ileal or Anastomotic Location of Lesions Does Not Impact Rate of Postoperative Recurrence in Crohn's Disease Patients Classified i2 on the Rutgeerts Score.

BACKGROUND: The Rutgeerts score with 5 grades of severity (i0-i4) is a suitable endoscopic model to predict clinical recurrence following ileocolonic resection in Crohn's disease (CD). Definition of grade i2 includes lesions confined to the ileocolonic anastomosis (i2a) or moderate lesions on the neo-terminal ileum (i2b). The aim of the present study was to evaluate the probability of clinical recurrence in i2a and i2b patients. METHODS: This multicenter retrospective study included all CD patients classified i2 at the first postoperative ileocolonoscopy. The primary outcome was to evaluate the probability of clinical recurrence in patients classified i2a and i2b. The secondary outcome was to compare the rate of global recurrence of CD. RESULTS: Fifty patients were included: 23 were classified i2a and 27 were classified i2b. The median duration of follow-up was 40 (18.0-80.4) months in the i2a group and 53.5 (25.0-69.0) months in the i2b group (p = 0.9). The probability of clinical recurrence was not significantly different between patients classified i2a and i2b (p = 0.64). Median time to clinical recurrence after the first ileocolonoscopy and probability of global CD recurrence were not different between the two groups (p ≥ 0.19). CONCLUSIONS: The rate of clinical postoperative recurrence is not different in i2a and i2b patients. These results suggest that the same therapeutic strategy should be used in all patients classified i2 on the Rutgeerts score whatever the location of postoperative CD recurrence.

Digestive perianastomotic ulcerations and Crohn's disease.

BACKGROUND AND AIMS: Digestive perianastomotic ulcerations (DPAU) have been occasionally reported as late complications of neonatal or childhood surgery. METHODS: We report here a series of 14 new cases. RESULTS: Cases were revealed by severe anemia, diarrhea, abdominal pain and growth failure in average 11.5 years after surgery. Ulcerations were most often multiple (n=11), located on the upper part of ileocolonic anastomoses (n=12) and difficult to treat. No granulomas were seen but lymphoid follicles were frequent. In addition, either ASCA or ANCA were positive in 4/9 tested patients and 8/11 genotyped patients exhibited a NOD2 mutation (P<0.0002 when compared to French healthy controls). CONCLUSION: Altogether, these findings argue for common physiopathological features between DPAU and Crohn's disease and for a prospective follow-up of selected operated children to explore the early events involved in gut inflammatory lesions.

Blind loop perforation after side-to-side ileocolonic anastomosis.

Blind loop syndrome after side-to-side ileocolonic anastomosis is a well-recognized entity even though its incidence and complication rates are not clearly defined. The inevitable dilation of the ileal cul-de-sac leads to stasis and bacterial overgrowth which eventually leads to mucosal ulceration and even full-thickness perforation. Blind loop syndrome may be an underestimated complication in the setting of digestive surgery. It should always be taken into account in cases of acute abdomen in patients who previously underwent right hemicolectomy. We herein report 3 patients who were diagnosed with perforative blind loop syndrome a few years after standard right hemicolectomy followed by a side-to-side ileocolonic anastomosis.
