Anal defecatory function in ulcerative colitis patients after total proctocolectomy and ileal pouch-anal anastomosis: a prospective cohort study

BACKGROUND

Total proctocolectomy (TPC) followed by ileal pouch-anal anastomosis (IPAA) remains the only viable option whenever different treatment modalities fail in patients with ulcerative colitis (UC).

OBJECTIVE

Prospective cohort pre/post study examining the anal defecatory function and competence in UC patients undergoing TPC plus IPAA using high-resolution anorectal manometry (HR-ARM).

PATIENTS

Patients undergoing TPC and IPAA were enrolled in the study and subjected to HR-ARM prior to and 6 months after surgery. The anal resting, squeeze and push pressures were recorded, together with the rectal sensation and the rectal balloon expulsion test. The number of bowel movements, symptoms/signs related to fecal incontinence, as well as the IBDQ-32 quality of life questionnaires were documented during both HR-ARM visits.

RESULTS

A total of 20 consecutive UC patients were recruited in our study. The mean (SD) number of bowel movements before the TPC plus IPAA was 10.1 (2.8), while the same number after the pouch surgery was 7.7 (3.1) [ P  = 0.01]. Symptoms or signs of fecal incontinence were noted in one of our patients prior to the operation; however, none of our patients reported any such symptoms after the pouch surgery. The median (IQR) IBDQ-32 questionnaire scores before and after surgery were 121.5 (13.5) and 142.5 (16.0) respectively. At the same time, the anorectal function remained intact since both the anal resting and squeeze pressures were not significantly changed.

CONCLUSION

UC patients subjected to TPC-IPAA exhibit improved bowel movements and a normal anal defecatory function and competence post-surgery.

Post-inflammatory polyps burden as a prognostic marker of disease-outcome in patients with inflammatory bowel disease

INTRODUCTION AND AIM

Post-inflammatory polyps (PIPs) are considered as indicators of previous episodes of severe inflammation and mucosal ulceration. Inflammatory bowel disease (IBD), namely Crohn's disease (CD) and ulcerative colitis (UC), exhibit a perpetuating, relapsing, and remitting pattern and PIPs is a frequent sequela of chronicity. The aim of this study was to determine whether a high PIPs burden is associated with a more severe disease course in patients with IBD.

METHODS

This was a multinational, multicentre, retrospective study. IBD patients previously diagnosed with PIPs were retrieved from the endoscopic database of each centre. PIPs burden was evaluated and associated with demographic and clinical data as well as factors indicating a more unfavorable disease course.

RESULTS

A total of 504 IBD patients with PIPs were recruited (male: 61.9%). The mean age at IBD diagnosis was 36.9 (±16.8) years. Most patients (74.8%) were diagnosed with UC. A high PIPs burden was present in 53.4% of patients. On multivariable Cox regression analysis, high PIPs burden was independently associated with treatment escalation (HR 1.35, 95% CI 1.04-1.75; P=0.024), hospitalization (HR 1.90; 95% CI 1.24 - 2.90; P=0.003), need for surgery (HR 2.28; 95% CI 1.17-4.44, P=0.02) and younger age at diagnosis (HR 0.99, 95% CI 0.98-0,99; p=0.003).

CONCLUSION

PIPs burden was associated with a more severe outcome. Future prospective studies should focus on the characterisation of PIPs burden as to further risk stratify this patient cohort.

Unusual mercury poisoning from tattoo dye

BACKGROUND

Tattoos have become very popular in modern societies due to the gradual change in aesthetics and psychosocial acceptability. Consequently, tattoo reactions are seen more commonly than in the past. Cutaneous lesions associated with tattoos can be divided into three major groups: allergic/granulomatous/lichenoid, infectious, and coincidental lesions. Early identification and proper treatment of these skin lesions is challenging and necessitates close coοperation of different medical specialties.

CASE DESCRIPTION

We report an unusual case of mercury poisoning in a young person manifested with local skin reactions following amateur tattooing. The tattoo induced inflammatory foreign body reactions and required multiple surgical excisions to be removed. The unique feature of this case is the use of the elemental form of mercury in the tattoo dye and the resulting mercury poisoning. The poisoning was confirmed by detection of mercury in blood, urine, and hair samples.

CONCLUSION

This is a rare case of tattoo-associated skin reaction and mercury poisoning by the elemental form of mercury contained in the tattoo dye. In the literature, many conditions have been documented in association with tattoos and the process of tattoo application, especially when red dyes are used, but no similar cases of elemental mercury poisoning from the tattoo dye exist.

Specific esophagogram to assess functional outcomes after Heller's myotomy and Dor's fundoplication for esophageal achalasia

Esophageal emptying assessed at the 'timed barium' esophagogram correlates well with symptomatic outcomes after pneumatic dilation for esophageal achalasia, although 30% of patients with satisfactory outcome exhibit partial improvement in emptying. The aim of the study was to investigate any correlation of esophageal emptying to symptomatic response after laparoscopic Heller's myotomy and Dor's fundoplication. 'Bread and barium' (transit time of a barium opaque bread bolus) and 'timed barium' (height of esophageal barium column 5 minutes after ingestion of 200-250 mL of barium suspension) esophagogram was used to assess esophageal emptying in 73 patients with esophageal achalasia before 1 and 5 years (31 cases) after laparoscopic myotomy and anterior fundoplication. Symptoms assessment was based to a specific score. At 1-year follow-up, excellent and good symptomatic results were obtained in 95% of the cases. Esophageal maximum diameter, esophageal transit time, and esophageal barium column were significantly correlated to each other and to symptom score postoperatively (P < 0.001). Complete and partial (<90% and 50-90% postoperative reduction in barium column, respectively) emptying was seen in 55% and 31% of patients with excellent result. Patients with a pseudodiverticulum postoperatively had a more delayed esophageal emptying than those without. Symptomatic outcome and esophageal emptying did not deteriorate at 5-year follow-up. Esophageal emptying assessed by 'barium and bread' and 'timed barium' esophagogram correlated well with symptomatic outcome after laparoscopic myotomy for esophageal achalasia. Complete symptomatic relief does not necessarily reflect complete esophageal emptying. Outcomes do not deteriorate by time. Because of wide availability, esophagogram can be applied in follow-up of postmyotomy patients in conjunction with symptomatic evaluation.
