Sigmoid-urachal fistula is exceedingly rare in adults and only a few cases have been reported in the world literature. We present the case of a 54-year-old man with symptomatic sigmoid-urachal fistula managed successfully with a laparoscopic assisted high anterior resection, primary anastomosis and an en bloc resection of the urachal cyst and the involved cuff of bladder.

Background Treatment for peritoneal malignancy (PM) can include cytoreductive surgery (CRS) and heated intrapertioneal chemotherapy (HIPEC) and is associated with morbidity and mortality. Physical, psychological and nutritional outcomes are important pre-operatively. The aim of this pilot study was to investigate these outcomes in patients with PM before and after CRS-HIPEC. Methods Between June 2018 and November 2019, participants were recruited to a single-centre study. Primary outcome was cardiopulmonary exercise testing (CPET) variables oxygen uptake (VO2) at anaerobic threshold (AT) and at peak. Secondary outcome measures were upper and lower body strength, health related quality of life (HRQoL) and the surgical fear questionnaire. Exploratory outcomes included body mass index, nutrient intake and post-operative outcome. All participants were asked to undertake assessments pre CRS-HIPEC and 12 weeks following the procedure. Results Thirty-nine patients were screened, 38 were eligible and 16 were recruited. Ten female and 6 male, median (IQR) age 53 (42–63) years. Of the 16 patients recruited, 14 proceeded with CRS-HIPEC and 10 competed the follow up assessment at week 12. Pre-operative VO2 at AT and peak was 16.8 (13.7–18) ml.kg-1.min-1 and 22.2 (19.3–25.3) ml.kg-1.min-1, upper body strength was 25.9 (20.3–41.5) kg, lower body strength was 14 (10.4–20.3) sec, HRQoL (overall health status) was 72.5 (46.3–80) % whilst overall surgical fear was 39 (30.5–51). The VO2 at AT decreased significantly (p = 0.05) and HRQoL improved (p = 0.04) between pre and post- CRS-HIPEC. There were no significant differences for any of the other outcome measures. Conclusion This pilot study showed a significant decrease in VO2 at AT and an improvement in overall HRQoL at the 12 week follow up. The findings will inform a larger study design to investigate a prehabilitation and rehabilitation cancer survivorship programme.

Background: Video-Assisted Anal Fistula Treatment (VAAFT) is a novel minimally invasive & sphincter-saving technique for treating complex fistula-in-ano involving endoscopic assessment & treatment of perianal fistula. This retrospective, non-randomized, observational study is the first Australian study of VAAFT. It is also the longest study of VAAFT to-date. Methods: From January 2014 to September 2019, 59 patients with a complex anal fistula were identified via MRI & underwent VAAFT. Fourteen patients had undergone previous definitive surgery for anal fistula. Specialized Karl Storz video equipment (fistuloscope) was used in the procedure. The rigid fistuloscope was used to directly visualize the fistula tract/s & internal opening. Closure of the internal opening was then performed. The fistula tract/s were then treated via fulguration. The external opening was kept patent & dressed. Patients were then followed up for a mean 59.5 months. Results: 67.9% (n = 38) of patients achieved primary healing (needing nil further intervention) at a median of 13 weeks. 12.5% (n = 7) experienced healing followed by recurrence while 19.6% (n = 11) experienced non-healing. Of the recurrence/non-healing groups, 11/18 underwent repeat VAAFT with healing occurring in 10/11 patients at a median of 7 weeks. The mean operating time was 41.1 min. There were no major complications & continence scores were not affected. Three patients were lost to follow up. Conclusion: VAAFT is both effective & safe for the treatment of complex fistula-in-ano. Its minimally invasive nature means that in the instance of recurrence or persistence, VAAFT can be repeated with minimal morbidity & reasonable likelihood of success.

Background Emergency colorectal surgery tends to be associated with poorer outcomes compared to elective colorectal surgery. This study assessed the morbidity and mortality in patients undergoing emergency and elective colorectal resection in two metropolitan hospitals. Methods Patients were identified retrospectively from two institutions between April 2018 and July 2020. Baseline, operative and postoperative parameters were collected for comparative analysis between emergency and elective surgery groups. A binary logistic regression was performed to identify independent predictors of postoperative complications. Results During the study period, 454 patients underwent colorectal resection, 135 were emergency cases (29.74%) and 319 were elective cases (70.26%). Compared with elective resections, patients undergoing emergency resections were observed to have a higher American Society of Anesthesiologists (ASA) score of III to IV (53.33% vs. 38.56%) (P = 0.004). The mortality rate was similar between the emergency and elective group (1.48% vs. 0.63%, P = 0.369). The overall complication rate was higher in patients undergoing emergency resections (64.44% vs. 36.68%, P < 0.001), but the major complication rate was similar between groups (12.59% vs. 10.34%, P = 0.484). Independent predictors for postoperative complications included emergency surgery (Odds Ratio (OR) 2.77, 95% Confidence Interval (CI): 1.66 to 4.61) and an ASA Score of III to IV (OR 2.87, 95% CI: 1.84 to 4.47). Conclusion The overall complication rate was higher in patients undergoing emergency colorectal resection, however, rates of major complications and mortality were similar between groups. Higher complication rates reflect advanced disease pathology in patients who are more comorbid.
