Ileal-anal pouches: A review of its history, indications, and complications

The ileal pouch anal anastomosis(IPAA)has revolutionised the surgical management of ulcerative colitis(UC)and familial adenomatous polyposis(FAP).Despite refinement in surgical technique(s)and patient selection,IPAA can be associated with significant morbidity.As the IPAA celebrated its 40th anniversary in 2018,this review provides a timely outline of its history,indications,and complications.IPAA has undergone significant modification since 1978.For both UC and FAP,IPAA surgery aims to definitively cure disease and prevent malignant degeneration,while providing adequate continence and avoiding a permanent stoma.The majority of patients experience long-term success,but“early”and“late”complications are recognised.Pelvic sepsis is a common early complication with far-reaching consequences of long-term pouch dysfunction,but prompt intervention(either radiological or surgical)reduces the risk of pouch failure.Even in the absence of sepsis,pouch dysfunction is a longterm complication that may have a myriad of causes.Pouchitis is a common cause that remains incompletely understood and difficult to manage at times.10%of patients succumb to the diagnosis of pouch failure,which is traditionally associated with the need for pouch excision.This review provides a timely outline of the history,indications,and complications associated with IPAA.Patient selection remains key,and contraindications exist for this surgery.A structured management plan is vital to the successful management of complications following pouch surgery.

Jejunostomy Feeding Tube Placement in Gastrectomy Procedures: A Systematic Review

Many nutritional interventions have been developed to improve nutritional outcomes following upper gastrointestinal surgery. The aim of this systematic review was to investigate whether or not the routine use of intraoperative jejunostomy feeding tubes in partial and total gastrectomy procedures is warranted when assessing complications and nutritional benefits such as improved chemotherapy tolerance. An electronic search of MEDLINE, Web of Science, Embase and CINAHL databases was performed to identify studies which reported complications and/or post-operative outcomes of patients who received an intraoperative jejunostomy feeding tube in gastrectomy procedures. Five articles met the inclusion criteria (n = 636) with four retrospective cohort studies and one RCT. Studies varied in regards to the complications and nutritional outcomes reported. Jejunostomy feeding tube insertion may carry a risk of increased infectious complications but appears to reduce patient post-operative weight-loss and may improve chemotherapy tolerance. Due to the lack of high-quality studies, it is unclear if the routine use of an intraoperative jejunostomy feeding tube is indicated for all patients undergoing gastrectomy procedures or only those at a high-risk of post-operative malnutrition. More comprehensive research is recommended, particularly on the usefulness of home enteral nutrition post-gastrectomy.
