Aim: Crohn's disease (CD) is regarded as a wasting disease, yet there is a growing population of CD patients with a body mass index (BMI) of 35 and above. The rate of postoperative complications is relatively high in CD patients but might be even higher in CD with morbid obesity (MO).

Methods: This was a retrospective study using a prospectively maintained database of all patients undergoing Ileocolic resection for CD between 2014 and 2021 in two referral centres, comparing postoperative complication rates according to BMI.

Results: Three hundred and forty-six patients were identified. Sixty patients (17%) had a BMI over 30 kg/m², and 28 (8.1%) had a BMI of over 35 kg/m² (>35 group). The BMI >35 group had more women (78.6% vs. 52%, P < 0.1), a higher rate of patients not receiving an anastomosis (7.1% vs. 2.5%, P = 0.02), a higher rate of any postoperative surgical complication (32.1% vs. 25.2%, P = 0.4), with a higher rate of Clavien-Dindo ≥3 (14.3% vs. 7.2%, P = 0.25), a higher rate of stoma creation on reoperation for complications (7.2% vs. 1.7%, P = 0.04), a higher rate of 30-day readmission due to intra-abdominal abscess (10.7% vs. 4.7%, P = 0.2), but a lower rate of postoperative medical complications (3.6% vs. 15.7%, P < 0.01).

Conclusions: The rate of MO among CD patients requiring ileocolonic resection is on the rise. MO in this setting is associated with statistically non-significant increases in all surgical complications, severe complications, readmission, and a higher chance for a bailout stoma creation upon reoperation. However, MO seems to be a protective factor for medical postoperative complications, which might suggest better nutritional status.

Aim: Most of the literature on the environmental impact of surgery has analysed operating theatre practice in terms of its contribution to global warming (by greenhouse gas effects). The aim of this study was to assess the overall environmental impact of a complete perioperative pathway with and without implementation of an enhanced recovery programme (ERP).

Method: We compared two scenarios: an ERP scenario and a conventional scenario (CONV) for colorectal surgery. We carried out a lifecycle analysis for perioperative procedures, devices and consumables. We measured the impact on 17 environmental variables in addition to global warming.

Results: The overall environmental impact of ERP was 6% lower than that of conventional care. The reduction of impact due to ERP ranged from 5% for greenhouse gas emissions (18 kg CO₂ equivalent less per intervention) to 27% for water consumption (3 m³ less). The stages that had the most impact on the environment were the preoperative stage (essentially owing to patient travel) and the intraoperative stage with the surgical part (medical devices representing 83.3% of the impact of the procedure) and the anaesthesia part (halogenated gases and ventilation representing 54.9% of the impact of anaesthesia care).

Conclusion: This study found an ERP approach to be more eco-responsible than conventional care. This is an additional benefit of ERP implementation. The impact of ERP implementation might be further reduced by action on the preoperative and intraoperative stages.

Aim: Cryptoglandular anal fistulas carry a substantial burden to quality of life. Surgery is the only effective curative treatment but requires balancing fistula healing against pain, wounds and continence impairment. Sphincter-preserving procedures do exist but demonstrate variable rates of success. A lack of consistency and precision in outcome reporting and methodological quality hinders effective evidence-based decision-making. We aimed to establish a series of minimum reporting standards for interventional studies in idiopathic anal fistula, to eradicate low-quality studies, thus providing a consistent baseline of useful evidence.

Methods: An international group of 16 experts participated in a modified nominal group technique consensus. The nominal question was: 'What should be the minimum set of reporting standards for studies of intervention in idiopathic anal fistula?' The process was conducted between May and June 2023, culminating in a hybrid in-person/virtual meeting that took place at the Songdo International Proctology Symposium in June 2023.

Results: Initial idea generation resulted in 37 statements within the first round. Themes included variable reporting of follow-up and incontinence. Participants indicated their agreement via a 9-point Likert scale. Any statement achieving >70% consensus was retained. Subsequent group discussion condensed the list to 11 statements for further voting and a final minimum set of 12 reporting standards was created.

Conclusion: To date, this is the first study dedicated to developing minimum reporting standards for interventional studies in idiopathic anal fistula using a modified nominal group technique. These standards will instruct researchers in producing meticulous, high-quality studies that are accurate, transparent and reproducible.
