Pregnancy and stomas: a 9-year retrospective series at a major metropolitan hospital in Brisbane Queensland.

BACKGROUND: Over 42 000 Australians live with a stoma, and this number increases annually. Pregnancy in stoma patients is a rare but complex condition and there is limited published literature regarding surgical and obstetric complications in pregnant stoma patients. The aim of this paper was to review stoma outcomes, perinatal morbidity and mortality, and early postpartum period in pregnant stoma patients. METHODS: Data was retrospectively obtained on women of childbearing age, with a stoma, who had been pregnant and birthed in the last nine years at the Royal Brisbane and Women's Hospital between January 2014 to December 2022. Data recorded included patient demographics, type of stoma, indication for stoma, need for additional abdominal surgeries, method of conception, pregnancy complications, length of stay, neonatal outcomes and post pregnancy stomal complications. RESULTS: In total, there were 16 births from 13 mothers with stomas. Of 10 births to IBD patients, 40% experienced a serious stomal complication. Caesarean section (CS) rate was 90% for IBD and 83% for non-IBD. In-vitro fertilisation rates were 40% in IBD patients and 0% in non-IBD patients. The average gestational age at delivery was 36 weeks in IBD and 35 weeks non-IBD patients. Neonates delivered to IBD mothers had a birth weight under 2500g in 40% of cases and in non IBD mothers at 33.3% (p = 0.62). Of the sixteen births there was five complications (31.25%) associated with the stoma either during pregnancy or during the sixty-day postpartum period. CONCLUSION: Pregnancy in stoma patients is a rare occurrence and appears to be associated with high rates of CS, preterm delivery, low birth weight and stomal complication.

Endoscopic findings after CT proven acute diverticulitis: a systematic review and meta-analysis.

BACKGROUND: Traditionally, international guidelines recommend patients with acute diverticulitis should be followed up with a colonoscopy 6-8 weeks after discharge. However, the need for an interval colonoscopy has been increasingly challenged in the setting of computed tomography (CT). Previous meta-analyses have included studies which combined suspected rather than imaging confirmed diverticulitis and often without correlation with endoscopic findings. This meta-analysis aims to investigate endoscopic findings of patients with CT confirmed diverticulitis. METHODS: An electronic search of Medline, PubMed, Cochrane Library, Embase, CINAHL, Web of Science, Scopus, Clinicaltrials.gov and WHO ICTRP was performed up to October 18, 2021. Studies which reported CT confirmed acute diverticulitis in adults and who underwent endoscopic follow-up with either a colonoscopy or flexible sigmoidoscopy were included. Studies were excluded if diverticulitis was diagnosed by clinical grounds alone, ultrasound, barium enema, or other non-CT forms of imaging. RESULTS: A total of 68 studies with 13 905 patients were included. Median age was 58 years and male to female ratio was 0.84. Cancer was detected in 2.0% and advanced adenoma in 3.8%. Complicated diverticulitis had 9.2 higher odds of cancer compared to uncomplicated diverticulitis (95% CI 4.42-19.08, P < 0.001). Adenomas were detected in 17%. Of those diagnosed with colorectal cancer, 85% were concordant with the site of the diverticulitis on CT while 15% were incidental findings. CONCLUSION: Routine colonoscopic follow up should be recommended in medically fit patients who have CT proven acute diverticulitis due to the higher than population prevalence of colorectal cancer and advanced adenomas.

Skin to origin of mesenteric artery study (STOMA): prospective study of distances between stoma location and proximal superior mesenteric artery.

BACKGROUND: Traditional siting of stomas, in the lower abdomen, has been guided by surgical dogma lacking evidence. In the lower abdomen, the combination of a thick and pendulous abdominal apron, can create a challenging and suboptimal site for a stoma. The anatomical determinant limiting delivery of a stoma to the abdominal skin is the distance of the SMA from the lower border of the pancreas. The aim of this cross-sectional study was to compare the distance between the traditional stoma site, and upper abdominal stoma sites, to both the superior mesenteric artery (SMA) origin and SMA at the inferior border of the pancreas on abdominal computed tomography (CT). METHODS: A cross-sectional study at a single academic university hospital of adult patients who underwent abdominal CT in Australia. RESULTS: Two hundred and thirteen patients were included. Stoma sites in the upper abdomen were 57-76 mm shorter to the origin of the SMA and inferior border of the pancreas than those positioned at the traditional stoma site (P < 0.001). The mean panniculus thickness in the upper abdomen was 10 mm thinner than in the lower abdomen and increased with increasing BMI (P < 0.001). The ratio between the distance from the xiphisternum to umbilicus, and the umbilicus to pubic symphysis, was 1.10; this ratio increased with increasing BMI. CONCLUSION: The distance of the SMA to the skin is always shorter in the upper abdomen compared to the traditional stoma site. Consideration should be given to placing stomas in the upper abdomen, particularly in overweight or obese patients.
