    Notes: Abstract This article examines the effect of ileal pouch-anal (n=134) and coloanal (n=16) anastomoses on resting anal canal pressures in 150 patients. METHODS: Patients underwent anal manometry before ileal pouch-anal anastomosis (IPAA) and coloanal anastomosis (CAA) and again six weeks after ileostomy closure following these procedures. A water-perfused catheter system with four radial ports was used for manometry, pressures being recorded during both station and continuous pull through. RESULTS: Patients with IPAA were younger than those with CAA (34 years vs. 50 years) and had a different ratio of hand-to-stapled anastomosis (1∶2.6 vs. 1.3∶1). All CAA patients had had rectal cancer while IPAA patients suffered mainly from ulcerative colitis (n=114) or familial polyposis (n=10). The mean preoperative resting pressure for all patients was 79 mmHg (75–87, 95 percent confidence limit) and the mean fall in this pressure after surgery was 25 mmHg (−21 to −29, 95 percent confidence limit). There was no difference in preoperative pressure or fall between handsewn and stapled anastomoses, or between IPAA and CAA. CONCLUSION: There was a significant relationship between preoperative pressure and change in pressure that held true for all subgroups (change=−0.7 × preoperative pressure + 31,r=0.69). Analysis of the functional results confirmed that patients with high preoperative pressure are at risk for severe falls after surgery and are not guaranteed a good result. Conversely, patients with low preoperative pressures may actually have an increase with surgery and are not always incontinent. Patients with low preoperative anal resting pressures should not be denied anastomosis to the anus if they are continent.

    Notes: Abstract This study reviews the recent overall experience in one colorectal surgery department with congenital presacral tumors in adults. 24 patients greater than 21 years of age, who underwent curative resection between January 1980 and August 1992, were analyzed retrospectively. The growths were divided into two broad categories: developmental cysts and chordomas. The most common presenting symptom was pain (19/24). A preoperative evaluation regimen is outlined in the study and includes use of CT scanning, MRI imaging, and possibly the use of endoluminal ultrasound to document the relationship of presacral tumors to pelvic viscera. There were 20 developmental cysts and 4 chordomas treated in this series. 15 of 19 developmental cysts were excised by a posterior approach alone, 2 were excised by an anterior approach alone, and 3 were treated by a combined approach. Trans-sacral excision was carried out in 4 patients with developmental cysts. One chordoma was resected posteriorly and the other 3 through a combined anterior and posterior approach. Three recurrences were diagnosed after excision of developmental cysts at 8, 18, and 41 months postoperatively. Recurrence occurred in 3 of 4 chordoma patients after 25, 32, and 55 months. Reexcision was carried out in all patients. None of the developmental cyst cases developed a second recurrence but 2 of the 3 chordoma patients have recurred, but have undergone local irradiation, which has controlled their disease. A detailed surgical treatment plan is outlined in this article, emphasizing that total excision be the goal surgery, even if this requires a combined anterior and posterior approach. In cases of recurrence of both development cysts and chordoma, re-excision is a reasonable therapeutic option.

    Description / Table of Contents: Résumé Le risque d'explosion accidentelle de l'intestin résultant de l'emploid d'un bistouri électrique est faible. Seul deux cas d'explosion de l'intestin grêle ont été à ce jour décrits. Nous relatons un cas d'explosion de l'intestin grêle survenant au cours d'une stricturoplastie chez un patient porteur d'une sténose chronique sur maladie de Crohn. Afin de prévenir la survenue d'une telle complication dramatique, nous proposons qu'avant toute incision l'on décomprime proximalement l'intestin et que l'on renonce également à l'emploi du bistouri électrique.
    Notes: Abstract Explosion injury to the intestinal tract resulting from electrocautery is a rare occurrence. Only two small bowel explosions have been described previously. Here we describe an explosion of small bowel during strictureplasty in a patient with chronic obstructing Crohn's disease. Recommendations to avoid this disastrous complication include proximal decompression prior to incision and, in some cases, it may be wise to avoid electrocautery altogether.

    Description / Table of Contents: Résumé Au cours des 8 ans passés, 61 patients avec hidradénite supparative (HS) ont été traités à cette institution. 24 avaient aussi un diagnostic de maladie de Crohn (38%). Cette pathologie double est examinée en détail dans une revue rétrospective. Il y avait 11 hommes et 13 femmes d'un âge moyen de 39 (18–75 ans). La maladie de Crohn était iléale chez 1 patient, iléocolique chez 4 et affectait le colon seulement chez 19. Le diagnostic de malade de Crohn était antérieur à celui de HS en moyenne de 3,5 ans. A l'époque de la revue, 22 patients avaient une stomie, 23 avaient subi une laparotomie et 17 avaient perdu le rectum. L'hidradénite suppurative est survenue dans les zones périnéales ou périanales chez tous les patients mais occupait aussi d'autres lieux dans 20 cas. Une greffe cutanée a été faite chez 9 et des traitements locaux chez 19 patients. Des granulomes ont été trouvés dans la peau excisée chez 6 malades mais ces découvertes n'étaient pas associées avec un mauvais pronostic. Avec un recul moyen de 3,2 ans après la plus récente intervention chirurgicale pour hidroadénite (1 à 11 ans) 11 étaient asymptomatiques pour leur hidroadénite, 11 avaient des symptômes et 2 étaient perdus de vue. Ces faits montrent que HS peut coexister avec la maladie de Crohn rectocolique, compliquant le diagnostic et la traitement des patients ches lesquels elle survient. Un accroissement de l'appréciation de cette possibilité est recommandée.
    Notes: Abstract Over the last 8 years, 61 patients with hidradenitis suppurativa (HS) have been treated at this institution. Twenty-four have also had a diagnosis of Crohn's disease (38%). This dual pathology is examined in detail in this retrospective review. There were 11 males and 13 females with a mean age of 39 years (range 18 to 75 years). The Crohn's disease was ileal in 1 patient, ileocolic in 4, and affected the large bowel only in 19. The diagnosis of Crohn's disease predated that of HS by an average of 3.5 years. At the time of review, 22 patients had a stoma, 23 had undergone laparotomy and 17 had lost their rectum. Hidradenitis suppurativa occurred in the perineal or perianal area in all patients but involved other sites in 20 cases. Skin grafting had been done in 9 and local procedures in 19 patients. Granulomas were found in excised skin in 6 cases but this finding was not associated with a poor outcome. At a mean follow-up of 3.2 years from the most recent surgery for HS (range 1 to 11 years) 11 were asymptomatic for HS, 11 had symptoms and no follow up was available in 2. These data show that HS may coexist with Crohn's proctocolitis, complicating the diagnosis and management of patients in whom it occurs. An increased appreciation of the possibility is recommended.

    Notes: Abstract Colonoscopy is sometimes painful for the patient and often difficult for the endoscopist, but it is hard to predict how difficult or painful the examination will be. The purpose of this study was to identify factors that influence difficulty and pain during colonoscopy. Some 1,284 consecutive patients undergoing office colonoscopy by three endoscopists were prospectively studied. A standard questionnaire was completed by the nursing staff, who assessed the degree of difficulty and pain associated with each exam on a four-point scale. There were 682 men and 551 women (sex not recorded in 51). There was no pain in 27%, mild pain in 39%, moderate pain in 25%, and severe pain in 9%. There was no difficulty in 25%, mild difficulty in 33%, moderate difficulty in 28%, and severe difficulty in 14%. Colonoscopy was significantly easier (P〈0.001, chi square) and less painful (P〈0.001, chi square) in patients after sigmoidectomy. It was more painful after hysterectomy (P〈0.05, chi square) and more difficult and painful in women than in men (P〈0.01, chi square). There were significant differences between endoscopists in the assessment of pain associated with colonoscopy. Most colonoscopies are associated with little or no pain (66%) and are easy or only mildly difficult to perform (58%). Patients who have had sigmoid resection are especially easy and painless to examine while women, especially after hysterectomy, are at higher risk of having a painful experience. Colonoscopy technique can influence the amount of pain experienced by the patient.
