Treatment for acute uncomplicated diverticulitis without antibiotherapy: systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Use of antibiotics in selected cases of acute uncomplicated diverticulitis (AUD) has recently been questioned. OBJECTIVE: The aim of this study is to examine the safety and efficacy of treatment regimens without antibiotics compared with that of traditional treatments with antibiotics in selected patients with AUD. DATA SOURCES: PubMed, Medline, Embase, Web of Science, and the Cochrane Library. METHODS: A systematic review was performed according to PRISMA and AMSTAR guidelines by searching through Medline, Embase, Web of Science, and the Cochrane Library for randomized clinical trials (RCTs) published before December 2022. The outcomes assessed were the rates of readmission, change in strategy, emergency surgery, worsening, and persistent diverticulitis. STUDY SELECTION: RCTs on treating AUD without antibiotics published in English before December 2022 were included. INTERVENTION: Treatments without antibiotics were compared with treatments with antibiotics. MAIN OUTCOME MEASURES: The outcomes assessed were the rates of readmission, change in strategy, emergency surgery, worsening, and persistent diverticulitis. RESULTS: The search yielded 1163 studies. Four RCTs with 1809 patients were included in the review. Among these patients, 50.1% were treated conservatively without antibiotics. The meta-analysis showed no significant differences between nonantibiotic and antibiotic treatment groups with respect to rates of readmission [odds ratio (OR)=1.39; 95% CI: 0.93-2.06; P =0.11; I2 =0%], change in strategy (OR=1.03; 95% CI: 0.52-2,02; P =0.94; I2 =44%), emergency surgery (OR=0.43; 95% CI: 0.12-1.53; P =0.19; I2 =0%), worsening (OR=0.91; 95% CI: 0.48-1.73; P =0.78; I2 =0%), and persistent diverticulitis (OR=1.54; 95% CI: 0.63-3.26; P =0.26; I2 =0%). LIMITATIONS: Heterogeneity and a limited number of RCTs. CONCLUSIONS: Treatment for AUD without antibiotic therapy is safe and effective in selected patients. Further RTCs should confirm the present findings.

Early laparoscopic cholecystectomy in oldest-old patients: a propensity score matched analysis of a nationwide registry.

The role of early laparoscopic cholecystectomy (ELC) in "oldest-old" patients with acute calculous cholecystitis (ACC) is still controversial. The aim of this study is to assess the safety of ELC for ACC in ≥ 85-year-old patients. Multicentric retrospective study that analysed data of patients who underwent ELC for ACC between 2013 and 2018. Patients ≥ 85-year-old (oldest-old patients) were compared with younger patients, before and after propensity score matching (PSM). The main outcomes were mortality, post-operative complications, length of stay (LOS), and readmissions. The study included 1670 patients. The unmatched comparison revealed a selection bias towards the oldest-old group, which was associated with higher Charlson Comorbidity Index (5 vs 1, p < 0.001), more ASA III/IV subjects (54.2% vs 19.3%, p < 0.001), class II/III ACC (80.1% vs 69.1%, p = 0.016) and higher Chole-Risk Score (p > 0.001). The oldest-old also required more conversion to open surgery (20% vs 10.3%, p = 0.005). Postoperatively, they had a higher 90-day mortality rate (7.6% vs 1%, p < 0.001), more total complications (40.6% vs 17.7%, p < 0.001), complications ≥ IIIa Clavien-Dindo (14.4% vs 5.8%, p = 0.002), longer LOS (6 vs 5 days, p < 0.001), and more readmissions (6.6% vs 2.6%, p < 0.001). After PSM (n = 206), the two groups were comparable in terms of baseline characteristics and intraoperative outcomes. No differences were observed in post-operative complications; bile leak; incisional, intrabdominal, urinary or respiratory tract infections; LOS or readmissions. In the oldest-old, ELC for ACC is still associated with significant morbidity and mortality. However, it seems to be safe in selected patients. Therefore, age itself should not be regarded as a contraindication to ELC for ACC.

Laparoscopic Cholecystectomy for Acute Cholecystitis: Is the Surgery Still Safe beyond the 7-Day Barrier?

BACKGROUND: The optimal timing for early laparoscopic cholecystectomy (ELC) in patients with acute calculous cholecystitis (ACC) is still controversial. The aim of this study was to assess the outcomes of ELC in patients with delayed presentation. METHODS: Retrospective analysis of 381 patients who underwent ELC for ACC between January 2010 and September 2018. Included patients were classified into two groups according to the timing of surgery from the onset of symptoms: group 1 (G1) within the first 7 days and group 2 (G2) beyond 7 days. RESULTS: There were no significant differences regarding conversion rate (G1 8.6% vs. G2 11.8%; p = 0.527), operative time (G1 100 min [75-120] vs. G2 120 min [71-150]; p = 0.060), bile duct injuries (G1 0.3% vs. G2 0%; p = 1), major postoperative complications (G1 11% vs. G2 5.9%; p = 0.557), reoperation rates (G1 1.4% vs. G2 0%; p = 1), length of stay (G1 4 days [3-7] vs. G2 5 days [3-7]; p = 0.539), readmissions (G1 3.7% vs. G2 5.9%; p = 0.633) and costs (G1 6035 € [3693-8330] vs. G2 7243 € [4921-11,336]; p = 0.395). CONCLUSION: ELC may be considered for patients with ACC who can tolerate surgery with more than 1 week of symptom duration.
