Emergency Surgery in Acute Diverticulitis: A Systematic Review.

BACKGROUND: Acute diverticulitis is a common disease with public health significance. Many studies with a high level of evidence have been published recently on the surgical management of acute diverticulitis. OBJECTIVE: The aim of this systematic review was to define the accurate surgical management of acute diverticulitis. DATA SOURCES: Medline, Embase, and the Cochrane Library were sources used. STUDY SELECTION: One reviewer conducted a systematic study with combinations of key words for the disease and the surgical procedure. Additional studies were searched in the reference lists of all included articles. The results of the systematic review were submitted to a working group composed of 13 practitioners. All of the conclusions were obtained by full consensus and validated by an external committee. INTERVENTIONS: The interventions assessed were laparoscopic peritoneal lavage, primary resection with anastomosis with or without ileostomy, and the Hartmann procedure, with either a laparoscopic or an open approach. MAIN OUTCOME MEASURES: Morbidity, mortality, long-term stoma rates, and quality of life were measured. RESULTS: Seventy-one articles were included. Five guidelines were retrieved, along with 4 meta-analyses, 14 systematic reviews, and 5 randomized controlled trials that generated 8 publications, all with a low risk of bias, except for blinding. Laparoscopic peritoneal lavage showed concerning results of deep abscesses and unplanned reoperations. Studies on Hinchey III/IV diverticulitis showed similar morbidity and mortality. A reduced length of stay with Hartmann procedure compared with primary resection with anastomosis was reported in the short term, and in the long term, more definite stoma along with poorer quality of life was reported with Hartmann procedure. No high-quality data were found to support the laparoscopic approach. LIMITATIONS: Trials specifically assessing Hinchey IV diverticulitis have not yet been completed. CONCLUSIONS: High-quality studies showed that laparoscopic peritoneal lavage was associated with an increased morbidity and that Hartmann procedure was associated with poorer long-term outcomes than primary resection with anastomosis with ileostomy, but Hartmann procedure is still acceptable, especially in high-risk patients.

Management of Acute Appendicitis in Ambulatory Surgery: Is It Possible? How to Select Patients?

OBJECTIVE: Establish a protocol of management of acute appendicitis (AA) in ambulatory surgery (AmbSurg) on the basis of preoperative criteria. BACKGROUND: Ambulatory laparoscopic appendectomy (LA) for AA has not been yet reported. METHODS: All patients who underwent LA between 2010 and 2012 were reviewed. A multivariate analysis was performed to create a predictive score of discharge within the first 24 hours. The score was prospectively used on every AA from January 1, 2013, to December 15, 2013. All patients with 5 or 4 points were proposed for AmbSurg. RESULTS: A total of 468 patients were included retrospectively, 181(38.7%) were discharged within the first 24 hours. In multivariate analysis, predictive factors of early discharge were body mass index less than 28 kg/m, white cell count less than 15,000/mL, C-reactive protein less than 30 mg/L, no radiological signs of perforation, and appendix diameter of 10 mm or smaller. Rate of discharge at day 1 was 72%, 45%, 39%, 21%, 0%, and 0% according to the score 5 to 0 (P < 0.0001). Prospectively, 184 patients had AA and 103 (56%) had a score of 4 or 5. Thirty-eight underwent ambulatory LA [16 (42%) patients were postponed to the next day and went back home]. All patients were directly discharged from recovery room, except 1 (2.6%) patient, after a mean hospital stay of 8.4 hours ± 6.9 hours. A total of 146 patients underwent LA in conventional surgery and 58% were discharged at day 1. Rate of early discharge was significantly associated with the score ranging from 0% to 92% for a score 0 or 5, validating prospectively the score (P < 0.0001). CONCLUSIONS: We establish a simple validated predictive score of early discharge. When applied to AmbSurg, it allowed us to select patients eligible with a success rate of 97%.

Abdominoperineal resection for squamous cell anal carcinoma: survival and risk factors for recurrence.

BACKGROUND: Despite the results of combined chemoradiation therapy for anal canal squamous cell carcinoma (SCC), up to 30 % of patients will undergo abdominoperineal resection (APR). The aim of this study was to evaluate oncologic outcomes, survival, and recurrence, following APR for anal canal SCC performed in a single center over a 13-year period. METHODS: All patients who underwent APR for anal canal SCC between 1996 and 2009 were retrospectively included. Demographic data, details on treatments, pathological report, and follow-up were noted. Survival curves were plotted using the Kaplan-Meier method and potential prognostic factors were evaluated using Cox proportional hazards models. RESULTS: A total of 105 patients (77 women) were included. Indications for APR included tumor persistence (n = 42; 40 %), recurrence (n = 55; 52.4 %), or a contraindication to radiotherapy (n = 8; 7.6 %). Median follow-up was 33.3 months (range, 1.5-174.3 months). Overall survival and disease-free survival were, respectively, 61 and 48 % at 5 years. In multivariate analysis, tumor stage (T3 or T4), positive margin on pathologic examination and existence of distant metastases at the time of the surgery were associated with a poor prognosis. The indication for APR (persistent vs recurrent disease), gender, concurrent HIV infection, or performance of a VRAM flap did not influence OS or DFS. Overall recurrence rate was 42.6 % (n = 43 of 101). The type of recurrence did not exert a significant effect on survival (p = .4571). CONCLUSION: This study describes the largest single series of APR for anal carcinoma. Major prognostic factors for survival and recurrence were T status and involved margin. The 5-year overall survival was 60 %.
