- Anterior resection (AR) may result in defecatory dysfunction and the cause is multifactorial. The aim was to explore if dysfunction could be related to the part of the colon used for anastomosis (sigmoid or descending) and to identify other possible risk factors for bowel dysfunction after AR.This is a retrospective study based on prospectively registered data from a regional registry at the surgical department in Västmanland 1996–2019. Bowel function was registered at 1 year after AR or after stoma reversal. In total, 470 stage I–III rectal cancer patients had AR whereof 412 were included in this study.Clustering was seen in 57%, incontinence 29%, urgency 22%, and evacuatory dysfunction 16%. The part of the colon used for anastomosis, level of vascular tie, and gender were not significantly associated with defecatory dysfunction. The higher the anastomotic level, the lower the risk of incontinence (OR 0.75; CI 0.63–0.90; p < 0.001) and clustering (OR 0.78; CI 0.67–0.90; p < 0.001). Compared with patients without a loop-ileostomy, an increased risk of clustering (OR 1.89; 1.08–3.31; p = 0.03), incontinence (OR 2.48; 1.29–4.77; p < 0.01), and urgency (OR 4.61; CI 2.02–10.60; p < 0.001) was seen after loop-ileostomy closure. Preoperative radiotherapy had a negative impact on continence and clustering seen mainly in the unadjusted analysis.The part of the colon used for anastomosis was not a significantly associated functional outcome after anterior resection. Low anastomotic level and having had a diverting ileostomy were independent risk factors associated with negative functional outcomes.

- PURPOSE: The aim of this study was to determine if mechanical bowel preparation (MBP) influences the intramucosal bacterial colony count in the colon. MATERIALS AND METHODS: Macroscopically normal colon mucosa was collected from 37 patients (20 with and 17 without MBP) who were undergoing elective colorectal surgery at three hospitals. The biopsies were processed and cultured in the same laboratory. Colony counts of the common pathogens Escherichia coli and Bacteroides as well as of total bacteria were conducted. The study groups were comparable with regard to age, gender, antibiotics use, diagnosis and type of resection. RESULTS: MBP did not influence the median colony count of E. coli, Bacteroides or total bacteria in our study. CONCLUSIONS: MBP did not affect the intramucosal bacterial count in this study. Further studies are suggested to confirm these findings.

Prophylactic stoma mesh did not prevent parastomal hernias

- Parastomal herniation is reported in up to 50 % of patients with a colostomy. A prophylactic stoma mesh has been reported to reduce parastomal hernia rates. The aim of the study was to evaluate the rate of parastomal hernias in a population-based cohort of patients, operated with and without a prophylactic mesh at two different time periods. All rectal cancer patients operated with an abdominoperineal excision or Hartmann's procedure between 1996 and 2012 were included. From 2007, a prophylactic stoma mesh was placed in the retro-muscular plane. Patients were followed prospectively with clinical and computed tomography examinations. There were no differences with regard to age, gender, pre-operative albumin levels, ASA score, body mass index (BMI), smoking or type of surgical resection between patients with (n = 71) and without a stoma mesh (n = 135). After a minimum follow-up of 1 year, 187 (91 %) of the patients were alive and available for analysis. At clinical and computed tomography examinations, exactly the same parastomal hernia rates were found in the two groups, viz, 25 and 53 %, respectively (p = 0.95 and p = 0.18). The hernia sac contained omentum or intestinal loops in 26 (81 %) versus 26 (60 %) patients with and without a mesh, respectively (p = 0.155). In the multivariate analyses, high BMI was associated with parastomal hernia formation. A prophylactic stoma mesh did not reduce the rate of clinically or computed tomography-verified parastomal hernias. High BMI was associated with an increased risk of parastomal hernia formation regardless of prophylactic stoma mesh.

- Hartmann's procedure for rectal cancer patients is increasingly performed but few studies have reported the postoperative outcome. The purpose was to report postoperative complications and analyse risk factors in rectal cancer patients operated with Hartmann's procedure. To describe the selection and postoperative complication patterns, all bowel-resected rectal cancer patients were included. Population-based data were from the county of Vastmanland, Sweden. All rectal cancer patients operated with an elective bowel resection between 1996 and 2012 were included. Demographics and postoperative complications were prospectively registered and data retrospectively analysed. Of the 624 patients included, 396 (64 %) were operated with an anterior resection, 159 (25 %) with an abdominoperineal excision and 69 (11 %) a Hartmann's procedure of which 90 % were low Hartmann's. Patients operated with a Hartmann's procedure were significantly older, had higher ASA-score, poorer WHO performance score and lower serum albumin levels. Operative time for Hartmann's procedure was a median of 49 and 99 min shorter than after anterior resection and abdominoperineal excision, respectively, and entailed less bleeding. Complications related to the pelvic and perineal dissections were more common after abdominoperineal excision compared with anterior resection and Hartmann's procedure (32 vs. 9 and 13 %, p < 0.001). Few rectal cancer patients, operated with Hartmann's procedure, developed pelvic complications despite a higher age, more co-morbidities, metastases in different localities and functional inferiority when compared with the patients operated with anterior resection or abdominoperineal excision. Hartmann's procedure is a valid alternative procedure in the old and frail rectal cancer patient.
