    Revisiting large complex ventral hernia repair: multimodal hybrid technique deploying preoperative Botulinum Toxin A injection, laparoscopic anterior components separation and open mesh repair
    (2024) Hashmi , KS; Udeaja, YZ; Dastur, J; Allen, S; Das, P
    Abstract In the past, various techniques had been described to repair large complex ventral hernias. Laparoscopic technique of components separation showed low complication rates and better overall outcome. Recently, Botulinum Toxin A (BTA) has shown benefit in achieving tension-free repair. We describe here our multimodal technique combining BTA injection, laparoscopic anterior components separation (LACS) and open mesh repair. Ten consecutive cases performed over 3 years were studied. A standardised technique was used with a reasonably short learning curve. Patients who generally fit for general anaesthesia were offered surgery after detailed preoperative imaging work up and informed consent. Demographic details, preoperative risk stratification, intraoperative and postoperative outcomes were recorded and analysed. A structured step by step management strategy was adopted. Total ten (n = 10) cases with median age of 42.5 years (range 28-76 years), male to female ratio of 8:2 and median BMI of 32.6 were included. Three patients had pre-existing stomas. Median diameter of hernial defect was 10 cm, IQR 4.8 cm and range of 6-20 cm. No intraoperative or immediate complications were observed. Median hospital stay was 6 days. Two seromas (20%) and two return to theatre (20%) were observed. One recurrence (10%) was observed after median follow-up of 32 months. No 90-day mortality was recorded. Multimodal technique of BTA injection, LACS and midline mesh repair is a reproducible, safe and effective option to repair large complex ventral hernias.

    Changes in social care after major emergency general surgery procedures
    (2024) Niaz, O; Khalil, A; Batt, MI; Sesby-Banjoh, O; Al-Fagih, O; Askari , A; Al-Taan , O
    Abstract Background: Emergency general surgery (EGS) is a major part of the provision of healthcare, and patients undergoing EGS are at elevated risk of morbidity and mortality. This study aimed to determine factors contributing to patients losing their independence and being discharged to residential and nursing homes having previously lived in their own residences. Methods: Our local data uploaded to the National Emergency Laparotomy Audit (NELA) (2014-2022) were analyzed. This national database encompasses all major EGS cases undertaken in the United Kingdom. The variables considered were patient demographics, American Society of Anesthesiologists score, admission and discharge dates, presenting pathology, operation type, and discharge destination. Comparative analyses segmented patients based on postdischarge EGS destinations. Multivariable logistic regression identified factors linked to residential/nursing home placement after discharge. Significance was set at P < .05. Results: Data from all patients in the NELA database (n = 1611) were analyzed. Approximately 1 in 10 patients older than 70 years never returned home. Patients requiring additional support were on average 8.6 years older (P = .008). At older than 80 years, the need for extra social support increased substantially with each increasing year in age, and those older than 85 years were more than twice as likely to require extra support than 80-year-olds (P < .001). Patients who died were 11.4 years older than those discharged without additional support (P < .001). Conclusion: A significant proportion of patients, particularly the elderly, do not return to their usual place of residence and require a higher level of care postemergency surgery. These important social factors need to be considered before operating given that they may have significant quality of life and economic implications.

    Impact of Gastrojejunostomy Anastomosis Diameter on Weight Loss Following Laparoscopic Gastric Bypass: A Systematic Review
    (2024) Al-Fagih, O.S; Zuberi , S; Niaz, O; Jambulingam , P; Whitelaw, D; Rashid, F; Adil, M.T; Jain, V; Al-Taan, O; Munasinghe, A; Askari , A; Iqbal , FM
    Abstract Laparoscopic Roux-en-Y gastric bypass (RYGB) is crucial for significant weight reduction and treating obesity-related issues. However, the impact of gastrojejunostomy (GJ) anastomosis diameter on weight loss remains unclear. We investigate this influence on post-RYGB weight loss outcomes. A systematic search was conducted. Six studies met the inclusion criteria, showing varied GJ diameters and follow-up durations (1-5 years). Smaller GJ diameters generally correlated with greater short-to-medium-term weight loss, with a threshold beyond which complications like stenosis increased. Studies had moderate-to-low bias risk, emphasizing the need for precise GJ area quantification post-operation. This review highlights a negative association between smaller GJ diameters and post-RYGB weight loss, advocating for standardized measurement techniques. Future research should explore intra-operative and AI-driven methods for optimizing GJ diameter determination.
