Outcomes of initially nonoperative management of diverticulitis with abscess formation in immunosuppressed patients. DIPLICAB study COLLABORATIVE group.

AIM: Management of diverticulitis with abscess formation in immunosuppressed patients (IMS) remains unclear. The main objective of the study was to assess short- and long-term outcomes between IMS and immunocompetent patients (IC). The secondary aim was to identify risk factors for emergency surgery. METHODS: A nationwide retrospective cohort study was performed at 29 Spanish referral centres between 2015-2019 including consecutive patients with first episode of diverticulitis classified as modified Hinchey Ib or II. IMS included immunosuppressive therapy, biologic therapy, malignant neoplasm with active chemotherapy and chronic steroid therapy. A multivariate analysis was performed to identify independent risk factors to emergency surgery in IMS. RESULTS: A total of 1395 patients were included; 118 IMS and 1277 IC. There were no significant differences in emergency surgery between IMS and IC (19.5% and 13.5%, p = 0.075) but IMS was associated with higher mortality (15.1% vs. 0.6%, p < 0.001). Similar recurrent episodes were found between IMS and IC (28% vs. 28.2%, p = 0.963). Following multivariate analysis, immunosuppressive treatment, p = 0.002; OR: 3.35 (1.57-7.15), free gas bubbles, p < 0.001; OR: 2.91 (2.01-4.21), Hinchey II, p = 0.002; OR: 1.88 (1.26-2.83), use of morphine, p < 0.001; OR: 3.08 (1.98-4.80), abscess size ≥5 cm, p = 0.001; OR: 1.97 (1.33-2.93) and leucocytosis at third day, p < 0.001; OR: 1.001 (1.001-1.002) were independently associated with emergency surgery in IMS. CONCLUSION: Nonoperative management in IMS has been shown to be safe with similar treatment failure than IC. IMS presented higher mortality in emergency surgery and similar rate of recurrent diverticulitis than IC. Identifying risk factors to emergency surgery may anticipate emergency surgery.

Diverticulitis with abscess formation: Outcomes of non-operative management and nomogram for predicting emergency surgery: The Diplicab Study Collaborative Group.

BACKGROUND: To assess short- and long-term outcomes from non-surgical management of diverticulitis with abscess formation and to develop a nomogram to predict emergency surgery. METHODS: This nationwide retrospective cohort study was performed in 29 Spanish referral centers, including patients with a first episode of a diverticular abscess (modified Hinchey Ib-II) from 2015 to 2019. Emergency surgery, complications, and recurrent episodes were analyzed. Regression analysis was used to assess risk factors, and a nomogram for emergency surgery was designed. RESULTS: Overall, 1,395 patients were included (1,078 Hinchey Ib and 317 Hinchey II). Most (1,184, 84.9%) patients were treated with antibiotics without percutaneous drainage, and 194 (13.90%) patients required emergency surgery during admission. Percutaneous drainage (208 patients) was associated with a lower risk of emergency surgery in patients with abscesses of ≥5 cm (19.9% vs 29.3%, P = .035; odds ratio 0.59 [0.37-0.96]). The multivariate analysis showed that immunosuppression treatment, C-reactive protein (odds ratio: 1.003; 1.001-1.005), free pneumoperitoneum (odds ratio: 3.01; 2.04-4.44), Hinchey II (odds ratio: 2.15; 1.42-3.26), abscess size 3 to 4.9 cm (odds ratio: 1.87; 1.06-3.29), abscess size ≥5 cm (odds ratio: 3.62; 2.08-6.32), and use of morphine (odds ratio: 3.68; 2.29-5.92) were associated with emergency surgery. A nomogram was developed with an area under the receiver operating characteristic curve of 0.81 (95% confidence interval: 0.77-0.85). CONCLUSION: Percutaneous drainage must be considered in abscesses ≥5 cm to reduce emergency surgery rates; however, there are insufficient data to recommend it in smaller abscesses. The use of the nomogram could help the surgeon develop a targeted approach.

Quality of life and outcomes after rubber band ligation for haemorrhoidal disease.

PURPOSE: The main objective of this study was to assess the impact on quality of life after rubber band ligation (RBL) in patients with symptomatic grade II-III haemorrhoids who did not improve after 6 months of conservative treatment, using quality of life scores. METHODS: This was a prospective cohort observational study where patients with haemorrhoidal disease and indication for RBL were included between December 2019 and December 2020. RBL was offered as first-line treatment in this group. Patient´s quality of life was assessed by scores: HDSS (Hemorrhoidal Disease Symptom Score) and SHS (Short Health Scale).Secondary objectives were: to evaluate the rate of patients requiring one or more RBL procedures, to establish the overall success rate of RBL and to analyse complications. RESULTS: A total of 100 patients were finally included. Regarding the impact on quality of life after RBL, a significant reduction was found in the HDSS and SHS scores (p < 0.001). The main improvement was found in the first month and it was maintained until the sixth month. A high degree of satisfaction with the procedure was reported by 76% of patients. The overall success rate of banding was 89%. A 12% complication rate was detected, the most frequent complication was severe anal pain (58.3%) and self-limiting bleeding (41.7%). CONCLUSION: Rubber band ligation, as a treatment for symptomatic grade II-III haemorrhoids that do not respond to medical treatment, leads to a significant improvement in patients' symptoms and quality of life. It also has a high degree of satisfaction between patients.

Biopsia selectiva de ganglio centinela en cáncer de mama, ¿está justificada la espera al resultado intraoperatorio? / Intraoperative sentinel node biopsy, is it worth the wait?

Objetivo: En nuestro centro, el estudio de la biopsia selectiva del ganglio centinela (BSGC) se realiza de forma intraoperatoria. El objetivo principal del presente trabajo es conocer qué proporción de pacientes se beneficia de la espera intraoperatoria al resultado de la BSGC. Material y métodos: Se ha realizado un análisis retrospectivo de pacientes intervenidas en nuestro centro entre el 1 de enero de 2018 y el 30 de junio de 2019. Se incluyeron mujeres con tumores T1-T2, tratadas mediante tumorectomía y BSGC estudiado mediante método one-step nucleic acid amplification (OSNA). Resultados: Se incluyeron 149 mujeres en el estudio. No se encontraron diferencias estadísticamente significativas en cuestión de datos demográficos entre el grupo tratado mediante linfadenectomía axilar (LA) y el grupo tratado exclusivamente con BSGC. Se realizaron 18 LA tras el análisis del GC estudiado de forma intraoperatoria. Solo en seis de los casos se extrajeron tres o más GC. La localización por cuadrante de la lesión, permeación linfovascular y carga tumoral total muestran diferencias estadísticamente significativas entre los grupos. En el análisis multivariante, únicamente la carga tumoral total (TTL) se establece como variable independiente de necesidad de LA. Conclusiones: La obtención del resultado de la BSGC de forma diferida permite disminuir el tiempo de anestesia de las pacientes y tiempo de ocupación de quirófano, ya que en el momento actual no se realiza ningún procedimiento adicional en un elevado porcentaje de casos.

Introduction: In our institution, the study of selective sentinel node biopsy (SLNB) is performed intraoperatively. The main objective of our study is to know the proportion of patients who benefits from the waiting of the results of SLNB. Methods: A retrospective analysis of patients operated on our center between January 1 st, 2018 and June 30, 2019 was carried out. We included women diagnosed with T1–T2 tumors, treated by lumpectomy and SLNB studied using OSNA method. Results: Our study included 149 women. There were not statistically significant differences in terms of demographic data between the group treated with axillary lymph node dissection (ALND) and exclusively SLNB group. After analysis of SLN intraoperatively, there were performed 18 axillary lymphadenectomies. Only in six of these 18 cases, three or more sentinel nodes were founded. The location of the tumor, the presence of lymphovascular permeation and the total tumor load (TTL) showed statistically significant differences between groups. Only the TTL was established as the independent factor of the need for ALND. Conclusions: Obtaining a deferred result of the SLNB allowed reducing the time of anesthesia and occupation of the operating room, since in a high percentage of cases an additional procedure is not performed.

Impact of interval timing to surgery on tumor response after neoadjuvant treatment for gastric cancer

INTRODUCTION: neoadjuvant chemotherapy (NACT) followed by radical surgery is the optimal approach for locally advanced gastric cancer (GC). Interval timing to surgery after NACT in GC is controversial. The aim of this study was to evaluate the impact of NACT interval time on tumor response and overall survival. MATERIAL AND METHODS: a retrospective analysis from a prospective database was performed at a single referral tertiary hospital, from January 2010 to October 2018. Patients were assigned to three groups according to the surgical interval time after NACT: < 4 weeks, 4-6 weeks and > 6 weeks. Univariate and multivariable analyses were performed in order to clarify the impact of NACT on post-neoadjuvant pathological complete response rate (ypCR), downstaging (DS) and overall survival (OS). RESULTS: of the 60 patients analyzed, 18 patients (30 %) had an interval time to surgery < 4 weeks, 26 (43.3 %) between 4-6 weeks and 16 (26.7 %) > 6 weeks. Two patients (3 %) had achieved ypCR and 37 patients (62 %) had achieved DS. There were no differences in DS rates among the interval time groups (p: 0.66). According to the multivariate analysis, only poorly differentiated carcinoma was significantly related to lower DS rates (p: 0.04). Cox regression analysis showed that the NACT interval time had no impact on OS. According to the multivariate analysis, > 25 lymph node harvested (HR: 0.35) and female sex (HR: 5.67) were OS independent predictors. CONCLUSIONS: the NACT interval time prior gastrectomy for locally advanced GC is not associated with ypCR or DS and has no impact on overall survival

Laparoscopic duodenojejunostomy as a treatment for Wilkie's syndrome. Analysis of a four cases series.

We present 4 cases of Wilkie's syndrome (WS) diagnosis in our Hospital between 2014-2019. WS is an infrequent disease, whose diagnosis can be challenging for patients suffering recurrent digestive symptoms. Our patients refered a history of chronic postprandial abdominal pain associated with vomiting, intestinal transit disorders or an uncontrolled weight loss. Abdominopelvic angio-CT was part of the research in all the cases, objectifying a decrease in the angle between Superior Mesenteric Artery (SAM) and Aorta below 25°. In case of chronic or refractory cases, the surgical treatment may be an option. Laparoscopic duodenojejunostomy constitutes the treatment of choice due its low rate of complications and acceptable results.
