Purpose:
Anastomotic leak (AL) after a low pelvic anastomosis is a devastating complication, with short- and long-term morbidity and increased mortality. Surgeons may employ various adjuncts in an attempt to reduce AL rates or mitigate their impact. These include the use of temporary diverting ileostomy (TDI), transanal or rectal tubes and pelvic drains. This questionnaire evaluates the preferences and routine use of these adjuncts in Australasian colorectal surgeons.
Methods:
A cross-sectional survey was administered to Australian and New Zealand colorectal surgeons on September 20, 2018. The study survey consisted of 15 questions exploring basic demographics and the number of rectal resections and ileal pouches performed in 12 months, along with the surgeon’s preference for the use of diverting stomas, rectal tubes, and pelvic drains.
Results:
There were 90 respondents to the survey (31.6%). Surgeons in Western Australia (71.4%) were more likely to use a mandatory TDI in colorectal extraperitoneal anastomoses than surgeons in Queensland (14.3%). South Australian surgeons are more likely to employ a mandatory TDI (100%) for ileal pouches than Queensland surgeons (42.9%). Rectal tubes are not commonly utilized (40.0% never use them), and pelvic drains are (45.6% in all cases). Surgeons consider a median AL rate of 15% was felt to justify the use of a TDI in low pelvic anastomoses and a median AL rate of 10% for ileal pouches
Conclusion
There is considerable geographical variation in colorectal surgical practice throughout Australia and New Zealand. While surgeons interrogate the same literature, there are presumably other factors that see translation into variations in clinical practice.

Purpose:
Anastomotic leakage (AL) is the anathema of colorectal surgery. Its occurrence leads to increased morbidity and mortality and a prolonged hospital stay. Much work has gone into studying various biomarkers in drain fluid to facilitate early detection of AL. This stage 2a development study aims to assess the safety and feasibility of reliably detecting the iodine in Gastrografin (GG; Bayer Australia Ltd.) in drain fluid and stool samples by dual-energy computed tomography (DECT).
Methods:
This is a prospective, observational, controlled, consecutive cohort study establishing the safety and feasibility of the detection of GG in surgical drain fluid and stool as a biomarker of AL when patients with a low pelvic colorectal anastomosis undergo luminal flushing of the rectal tube with GG.
Results:
Ten consecutive patients were allocated to the saline flush group and the following 10 to the GG flush group. Three patients in the saline flush group developed an AL. One patient in the GG flush group developed an AL. An elevation in the drain fluid GG was detected using DECT on the day of clinical deterioration. None of the patients in the control group were found to have a positive result on DECT.
Conclusion
This study demonstrates the safety of a novel approach to the early detection of AL from extraperitoneal colorectal anastomoses. The technique requires validation in a larger cohort and a multicenter study is planned to investigate the efficacy of GG rectal tube flushes as an early biomarker of AL in low pelvic anastomoses.

Hemangioblastomas are World Health Organization (WHO) Grade I neoplasms of the hindbrain and spinal cord, whose management can be complicated by preoperative hemorrhage. We report on a case of a young female in extremis with posterior fossa hemorrhage following rupture of a fusiform posterior meningeal artery aneurysm embedded within a medullary hemangioblastoma. We discuss management options, including operative staging and embolization, and review similar cases of hemangioblastoma associated with aneurysm.

BACKGROUND:
More than half of the disease burden in Uganda can be prevented through improving water, sanitation, and hygiene (WASH). In slum communities, water supply is insufficient but also highly contaminated; therefore, ensuring that the safe water chain is maintained by households is paramount to preventing water-related diseases. This study aimed at assessing knowledge and practices of households on safe water chain maintenance in slum communities in Kampala City, Uganda.
METHODS:
This was a community-based cross-sectional study carried out among 395 households in slum communities in Kampala, Uganda. Data were collected using a semi-structured questionnaire. Prevalence ratios (PRs) and their 95% confidence intervals were used as a measure of association between safe water chain management and associated knowledge and practice factors. The PRs were obtained using a multivariable modified Poisson regression with logarithm as the link function, with robust standard errors.
RESULTS:
Majority (76.7%, 303/395) of the households collected their water from a piped water system and paid for the water (72.9%, 288/395). Almost all (97.2%, 384/395) of the participants said that they knew the dangers associated with drinking unsafe water, boiled their drinking water (95.4%, 377/395), and used storage containers that minimize contamination (97.0%, 383/395). However, only (32.4%, 128/395) of the households satisfactorily maintained the safe water chain. Female- (adjusted PR = 1.82, 95% CI (1.19-2.78)) and student-led households (adjusted PR = 1.58, 95% CI (1.03-2.41)) and those whose heads had attained post-primary education (adjusted PR = 1.48, 95% CI (1.02-2.17)) were more likely to satisfactorily maintain the safe water chain. This was similar among members who thought most contamination occurs during storage (adjusted PR = 1.47, 95% CI (1.10-1.97)).
CONCLUSION
Only a third of the households maintained the safe water chain satisfactory. Female-led, student-led, and post-primary educated-led household and household that thought most contamination occurs during storage were more likely to maintain the safe water chain. There is a need to improve the level of awareness about the importance of the safe water chain among slum dwellers.
