RESUMO
INTRODUCTION: Delayed gastric emptying (DGE) is a common complication in surgery, but incidence and relevance following multivisceral resection are unknown. METHODS: Data from 100 consecutive patients treated for primary retroperitoneal sarcoma (RPS) were analyzed from our institutional prospectively maintained database from January 2019 to April 2020. DGE severity was graded according to the International Study Group of Pancreatic Surgery and classified as primary or secondary to other complications. The primary outcome was incidence and grade of clinically relevant DGE (grades B-C). Secondary outcomes were correlation with patient, tumor, and treatment characteristics, and non-DGE morbidity [Clavien-Dindo (CD) grade ≥ 3]. RESULTS: Forty-two patients developed DGE and 28 had clinically relevant DGE. DGE was primary in 10 patients and secondary in 18 patients; the most common associated complications were: infections (11/18, 61.1%), pancreatic leak (7/18, 38.9%), bleeding (6/18, 33.3%), and bowel leak (6/18, 33.3%). DGE was related to longer length of hospital stay (P < 0.001), ICU admission (P = 0.004), ICU length of stay (P = 0.001), postoperative complications (CD [Formula: see text] 3 in 14/28 in DGE patients vs 11/72 in no-DGE; P = 0.04), and re-operation (P = 0.03). With multivariate analysis, the independent risk factors for DGE were patient comorbidities (OR 1.05; 95% CI 1.01-1.1; P = 0.04) and tumor size (OR 1.05; 95% CI 1.0-1.1; P = 0.02). DISCUSSION: Following multivisceral resection, DGE is a clinically relevant event that can be caused by an underlying complication. Prompt diagnosis and treatment of both DGE and any underlying complications led to full recovery in all cases.

Pelvic soft tissue sarcomas (PSTS) are a rare, heterogeneous group of tumors. They have been usually analyzed with retroperitoneal sarcomas (RPS), but actually have key differences. Due to their unique anatomic location, symptomatic presentation of PSTS may be more common than RPS. Adequate imaging approach is paramount for guiding differential diagnosis, while preoperative biopsy is mandatory, especially when preoperative treatment may be considered as initial approach. The most frequent histologic subtype is leiomyosarcoma, which is different as expected in the retroperitoneum where liposarcoma is the commonest histology. Also solitary fibrous tumor is commonly diagnosed in the pelvis. Surgical approach for PSTS differs from that for RPS mainly due to anatomic relations. Similarly, in the lack of definite evidence from specific trials about neoadjuvant and adjuvant treatments, the anatomic constraints to obtain wide margins in the pelvis as well as the expected functional outcome in case of organ resections should be factored into decision for individualized treatment offer. Vascular and genitourinary involvement are frequent, as well as herniation through pelvic foramina. For these reasons a multidisciplinary surgical team should always be considered. Early referral of these patients to high-volume centers is critical and may impact on survival, given that optimal initial resection is a major predictor of curative treatment. International consensus on PSTS treatment is advocated, similarly to the recent efforts realized for RPS.

BACKGROUND: Breast conservative surgery (BCS) is an adequate treatment for patients with early breast cancer. Local recurrence is associated with diverse factors. Our objective was to evaluate risk factors associated with finding residual tumor in patients with positive margins in BCS. METHODS: Observational retrospective study, including patients diagnosed with breast cancer undergoing BCS between 2000 and 2016. Clinicopathological and treatment variables were collected. Main outcome was the finding of residual tumor on re-excision. Positive margins were defined as tumor present on ink. RESULTS: Three hundred and six patients underwent BCS. Mean age was 57 ± 12.2 years. Positive margins were found in 84 (27.4%) patients, 15 (4.9%) had unknown margin status, and 207 (67.6%) had negative margins. Seventy-eight patients from the positive margin group and 23 patients from the unknown/negative margin group were reintervened. Residual tumor was present in 41% of patients with positive margins and in 45% of patients with negative margins (P = .192). In univariate analysis, overweight (P = .04) and positive axillary lymph nodes (P = .02) were associated with residual tumor on re-excision. In multivariate analysis, postmenopausal status was a protective factor (HR .047, P = .30). Mean follow-up was 58.4 months and mean local recurrence-free survival (LRFS) was 56.4 months (.1-203.2), with no difference regarding margin status or residual tumor. DISCUSSION: Postmenopausal status was associated with a decreased rate of residual tumor in patients with positive margins. The presence of residual tumor on re-excision was not associated with a lower LRFS. These factors must be considered when positive margins are present in BCS.

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. (AU)
