Detection of methanogens in peri-appendicular abscesses: Report of four cases.

The aetiology of appendicular abscess is predominantly microbial with aerobic and anaerobic bacteria from gut flora. In this study, by using specific laboratory tools, we co-detected Methanobrevibacter oralis and Methanobrevibacter smithii among a mixture of enterobacteria including Escherichia coli, Enterococcus faecium and Enterococcus avium in four unrelated cases of postoperative appendiceal abscesses. These unprecedented observations raise a question on the role of methanogens in peri-appendicular abscesses, supporting antibiotics as an alternative therapeutic option for appendicitis, including antibiotics active against methanogens such as metronidazole or fusidic acid.

Early and late morbidity of local excision after chemoradiotherapy for rectal cancer.

Background: Local excision (LE) after chemoradiotherapy is a new option in low rectal cancer, but morbidity has never been compared prospectively with total mesorectal excision (TME). Early and late morbidity were compared in patients treated either by LE or TME after neoadjuvant chemoradiotherapy for rectal cancer.

Method: This was a post-hoc analysis from a randomized trial.

Long-term results of dynamic graciloplasty for severe fecal incontinence.

Background: Fecal incontinence is a common complaint. In the presence of extensive sphincter deterioration, after anorectal trauma, or failure of non-invasive surgical procedures, a sphincter reconstruction with dynamic graciloplasty can be proposed. The aim of our study was to evaluate the long-term results of dynamic graciloplasty.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for resectable peritoneal metastases is feasible in elderly patients.

The aim is to evaluate the feasibility and the prognosis of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for resectable peritoneal metastases (RPM) in elderly patients. Patients who underwent CRS with HIPEC for RPM between 2012 and 2018 in one tertiary reference center were retrospectively included and divided according to the age: Group A (< 65 years) and Group B (≥ 65 years). Postoperative outcomes and survivals were compared.
