Development of a specialist ileoanal pouch surgery pathway: a multidisciplinary patient-centred approach.

Background: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the gold standard procedure for ulcerative colitis refractory to medical treatment, as an alternative to permanent end ileostomy. Gaining experience in pouch surgery is difficult as the procedure is performed infrequently. This study presents an institutional initiative to promote standardisation of multidisciplinary care in IPAA surgery. Methods: A dedicated pathway for patients who had an IPAA or are considering IPAA surgery was developed among colorectal surgeons, gastroenterologists, paediatric colorectal surgeons, inflammatory bowel disease (IBD) nurses, dietitians, stoma nurses, trainees in colorectal surgery. Pathway items were discussed and finalised via emails and videoconferences.The pathway included triaging of patients referred for IPAA surgery, preoperative IBD multidisciplinary team discussion and management plan for surgery, surgical review prior to surgery, peer to peer counselling, surgical technique, postoperative short-term and long-term follow-up, audit, research and training in IPAA surgery. Results: A multidisciplinary preoperative pathway was developed and a stepwise approach to minimally invasive ileoanal pouch surgery was formalised. A dedicated one-stop ileoanal pouch clinic was established integrating endoscopy and imaging on the same day of the consultation with the surgical and gastroenterology team. The clinic reviewed 72 patients over 24 months, and during the same time 36 patients underwent IPAA surgery at our institution. Conclusions: We have described our initial experience in establishing a specialist IPAA surgery pathway and have proposed outcome measures that we hope will support a subspecialty IPAA service.

Colorectal Cancer and the Obese Patient: A Call for Guidelines.

The link between obesity and colorectal cancer has been well established. The worldwide rise in obesity rates in the past 40 years means that we are dealing with increasing numbers of obese patients with colorectal cancer. We aimed to review the existing guidelines and make recommendations specific to this group of patients. Upon comparing the current NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines ®), the guidelines from the European Society of Medical Oncology (ESMO) and the guidelines of the Japanese Society for Cancer of the Colon and Rectum (JSCCR), we observed that these did not take into consideration the needs of obese patients. We proceeded to make specific recommendations with regards to the diagnostic work-up, surgical pathways, minimally invasive technique, perioperative treatment, post-operative surveillance, and management of metastatic disease in this group of patients. Our review highlights the need for modification of the existing guidelines to account for the needs of this patient cohort. A multidisciplinary approach, including principles used by bariatric surgeons, should be the way forward to reach consensus in the management of this group of patients.

Management and Outcomes in Anal Canal Adenocarcinomas-A Systematic Review.

(1) Background: Anal canal adenocarcinomas constitute 1% of all gastrointestinal tract cancers. There is a current lack of consensus and NICE guidelines in the United Kingdom regarding the management of this disease. The overall objective was to perform a systematic review on the multitude of practice and subsequent outcomes in this group. (2) Methods: The MEDLINE, EMBASE, EMCARE and CINAHL databases were interrogated between 2011 to 2021. PRISMA guidelines were used to select relevant studies. The primary outcome measure was 5-year overall survival (OS). Secondary outcome measures included both local recurrences (LR) and distant metastases (DM). The Newcastle-Ottawa Scale (NOS) was used to assess the quality of studies retrieved. The study was registered on PROSPERO (338286). (3) Results: Fifteen studies were included. Overall, there were 11,967 participants who were demographically matched. There were 2090 subjects in the largest study and five subjects in the smallest study. Treatment modalities varied from neoadjuvant chemoradiotherapy (CRT), CRT and surgery (CRT + S), surgery then CRT (S + CRT) and surgery only (S). Five-year OS ranged from 30.2% to 91% across the literature. LR rates ranged from 22% to 29%; DM ranged from 6% to 60%. Study heterogeneity precluded meta-analysis. (4) Conclusions: Trimodality treatment with neoadjuvant chemoradiotherapy (CRT) followed by radical surgery of abdominoperineal excision of rectum (APER) appeared to be the most effective approach, giving the best survival outcomes according to the current data.

A review of the incidence of iatrogenic hernia in both laparoscopic and open colorectal surgery: Using CT as the gold standard of detection, cohort study.

PURPOSE: The incidence of incisional hernia varies considerably in the literature. The aim of our study was to calculate the incidence of various types of the occult iatrogenic hernias following colorectal surgery, both laparoscopic and open, using CT scan. METHODS: The study included all patients who underwent colorectal resection procedures in a colorectal surgery department over an 11 year period between 2001 and 2012 who went on to have a CT scan post surgery. The term iatrogenic hernia included all postoperative hernias at laparotomy incision site in the open colorectal subgroup, hernias at the site of specimen extraction or port site hernias in the laparoscopic colorectal subgroup, and parastomal hernias in both subgroups. RESULTS: The total number of diagnosed iatrogenic hernias was 74 (61 detected on CT scan and 13 repaired on clinical grounds). Out of the 74 diagnosed iatrogenic hernias, 23 (31.1%) required surgical repair; 11 in the LCR (6 incisional, 2 parastomal and 2 port site hernias) and 12 in the OCR (9 incisional and 3 parastomal). CONCLUSION: The incidence of iatrogenic hernias is underestimated. The use of CT will increase the number detected. There is no significant difference in the incidence of iatrogenic hernias between laparoscopic and open colorectal procedures.
