Acute appendicitis (AA) is the most common general surgical emergency. Early laparoscopic appendicectomy is the gold-standard management. SARS-CoV-2 (COVID-19) brought concerns of increased perioperative mortality and spread of infection during aerosol generating procedures: as a consequence, conservative management was advised, and open appendicectomy recommended when surgery was unavoidable. This study describes the impact of the first weeks of the pandemic on the management of AA in the United Kingdom (UK). ⋯ COVID-19 has changed the management of acute appendicitis in the UK, with non-operative management shown to be safe and effective in the short-term. Antibiotics should be considered as the first line during the pandemic and perhaps beyond.

Review Meta Analysis
Efficacy of transversus abdominis plane (TAP) block in colorectal surgery: a systematic review and meta-analysis.
Multimodal opioid-sparing analgesia is a key component of the enhanced recovery after surgery (ERAS) protocol for postoperative pain management. Transversus abdominis plane (TAP) block has contributed to the implementation of this approach in different kinds of surgical procedures. The aim of this study was to evaluate the efficacy of TAP block and its impact on recovery in colorectal surgery. ⋯ TAP block appears to provide both an effective analgesia and a significant reduction in opioid use on the first postoperative day after colorectal surgery. Its use does not seem to lead to increased postoperative complications.

Surgical strategies for acute perforated diverticulitis with generalised peritonitis remain controversial. This study aimed to meta-analyse trials comparing primary resection and anastomosis (PRA) to Hartmann's procedure (HP) for Hinchey III/IV diverticulitis. ⋯ This meta-analysis demonstrates that PRA used in the management of haemodynamically stable patients with Hinchey grade III/IV diverticulitis leads to a lower overall persistent stoma rate, with reduced morbidity compared with the traditional management.

Multicenter Study
Intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy: results from the CLIMHET study group.
Laparoscopic right hemicolectomy (LRHC) is increasingly performed for the treatment of right colon disease. Nevertheless, standardization of the surgical technique regarding the performance of intracorporeal (IC) or extracorporeal (EC) anastomosis is lacking. The purpose of this study was to compare short-term postoperative outcomes in patients who had laparoscopic right colectomy either with IC or EC. ⋯ Our results show that IC anastomosis in LRHC is associated with fewer medical complications and shorter hospital stays compared to EC anastomosis.

Near-infrared (NIR) fluorescence imaging has the potential to overcome the current drawbacks of sentinel lymph node mapping (SLNM) in colon cancer. Our aim was to provide an overview of current SLNM performance and of factors influencing successful sentinel lymph node (SLN) identification using NIR fluorescence imaging in colon cancer. ⋯ Several anatomical and technical difficulties make SLNM with NIR fluorescence imaging in colon cancer particularly challenging when compared to other types of cancer. As a consequence, reports of SLNM accuracy vary widely. Future studies should try to standardize the SLNM procedure and focus on early-stage colon tumors, validation of tracer composition, injection mode and improvement of real-time optical guidance.
