Outcomes of treatment of faecal incontinence with sacral nerve stimulation - a Finnish multicentre study.

AIM: The aim of this multicentre study is to report the results of sacral nerve stimulation (SNS) treatment for faecal incontinence (FI) in Finland and determine factors that could influence SNS treatment outcomes. METHOD: This is a national multicentre study, involving all patients tested for SNS implantation in Finland from 1999 to 2017. Data were collected retrospectively from electronic patient archives and analysed for possible effects on treatment outcome. RESULTS: Of the 432 patients with FI tested for SNS, 365 were women. Three hundred and thirteen (72.5%) of the tested patients advanced to permanent implantation of a stimulator. A successful final treatment outcome, with subjective alleviation of FI, was reported by 59.3% of the patients at the end of follow-up (mean 2.4 years, range 8 days to 13.3 years). Patients with obstetric sphincter injury and idiopathic FI had more permanent stimulator implantations than patients with iatrogenic injury (P = 0.012). Male patients had significantly worse test phase outcomes than female patients (P < 0.001). Age did not influence treatment outcome (P = 0.446) CONCLUSION: Subjective final success of SNS treatment for FI was achieved in 59.3% of patients at a mean of 2.4 years. Gender and the aetiology of FI influenced the test phase and final treatment outcome of SNS treatment.

Laparoscopic ventral rectopexy in male patients with external rectal prolapse is associated with a high reoperation rate.

BACKGROUND: Laparoscopic ventral rectopexy has been used to treat male patients with external rectal prolapse, but evidence to support this approach is scarce. The aim of this study was to evaluate the results of this new abdominal rectopexy surgical technique in men. METHODS: This was a retrospective multicenter study. Adult male patients who were operated on for external rectal prolapse using ventral rectopexy in five tertiary hospitals in Finland between 2006 and 2014 were included in the study. Patient demographics, detailed operative, postoperative and short-term follow-up data were collected from patient registers in participating hospitals. A questionnaire and informed consent form was sent to all patients. The questionnaire included scores for anal incontinence, obstructed defecation syndrome, urinary symptoms and sexual dysfunction. The main outcome measure was the incidence of recurrent rectal prolapse. Surgical morbidity, the need for surgical repair due to recurrent symptoms and functional outcomes were secondary outcome measures. RESULTS: A total of 52 adult male patients with symptoms caused by external rectal prolapse underwent ventral rectopexy. The questionnaire response rate was 64.4 %. Baseline clinical characteristics and perioperative results were similar in the responder and non-responder groups. A total of 9 (17.3 %) patients faced complications. There were two (3.8 %) serious surgical complications during the 30-day period after surgery that necessitated reoperation. None of the complications were mesh related. Recurrence of the prolapse was noticed in nine patients (17 %), and postoperative mucosal anal prolapse symptoms persisted in 11 patients (21 %). As a result, the reoperation rate was high. Altogether, 17 patients (33 %) underwent reoperation during the follow-up period due to postoperative complications or recurrent rectal or mucosal prolapse. According to the postoperative questionnaire data, patients under 40 had good functional results in terms of anal continence, defecation, urinary functions and sexual activity. CONCLUSIONS: Laparoscopic ventral rectopexy is a safe surgical procedure in male patients with external prolapse. However, a high overall reoperation rate was noticed due to recurrent rectal and residual mucosal prolapse. This suggests that the ventral rectopexy technique should be modified or combined with other abdominal or perineal methods when treating male rectal prolapse patients.

Does preoperative radiotherapy with postoperative chemotherapy increase acute side-effects and postoperative complications of total mesorectal excision? Report of the randomized Finnish rectal cancer trial.

BACKGROUND AND AIMS: In a randomized trial the effect of short-term preoperative radiotherapy and postoperative chemotherapy was studied in patients undergoing total mesorectal excision (TME) for clinically resectable rectal cancer. The primary endpoint was overall survival. The secondary endpoints published herein were the incidence of postoperative complications and adverse events with perioperative adjuvant therapy. MATERIAL AND METHODS: In 1995-2002, 278 eligible patients with stage II and stage III rectal cancer were randomly assigned to TME alone (surgery group) or to preoperative 25 Gy radio-therapy in 5 fractions and postoperative 5-fluorouracil and leucovorin chemotherapy in addition (RT+CT group). RESULTS: Anastomotic leakage rate did not significantly differ between the surgery and the RT + CT group, 20.6% vs. 27.4%. Postoperative infections (15.5 vs. 26.2%, p = 0.037) and perineal wound dehiscence (15.9 vs. 38.5%, p = 0.045) were more common after radiotherapy. Grade 3-5 adverse events were uncommon with preoperative radiotherapy (one, 0.7% with reversible lumbar plexopathy) and postoperative chemotherapy (hematologic in 10.8%, with one septic death, and gastrointestinal in 4.8%). CONCLUSIONS: Perioperative adjuvant therapy was generally well tolerated and did not lead to an increase in serious surgical complications. Wound infections and perineal wound dehiscence were more common in irradiated patients.

Frozen-section biopsy in perendoscopic diagnosis of Helicobacter pylori.

BACKGROUND: Our goal was to investigate how reliably Helicobacter pylori infection can be diagnosed from gastric biopsy specimens by frozen-section technique. PATIENTS AND METHODS: The series consisted of 105 consecutive outpatients who underwent diagnostic upper gastrointestinal endoscopy for abdominal complaints at Jorvi Hospital (Espoo, Finland) during the beginning of 1996. Endoscopic biopsies from antrum and corpus were taken for both frozen-section and traditional histology, the latter serving as reference (control) material. In the frozen-section technique, the biopsy specimens were transferred immediately to the pathology laboratory, were prefixed for 30 sec in 10% neutral formalin, were frozen in liquid nitrogen, and were cut into sections with a cryostat. The sections were stained for 10 minutes with 1% toluidine blue. The control biopsy specimens were fixed overnight in 10% neutral formalin and embedded in paraffin, and the sections were stained with the modified Giemsa method. RESULTS: In the diagnosis of H. pylori infection, both the sensitivity and the specificity of the frozen-section technique were 98% compared to the findings in the reference series. One false-negative result occurred among 41 positive cases, and one case erroneously was classified positive among 64 cases that were negative for H. pylori in the ordinary histology. The frozen-section technique slightly underestimated the degree of colonization of the gastric mucosa by H. pylori, compared to the findings in the reference material. In the diagnosis of gastritis (chronic inflammation of any degree), the sensitivity and specificity of frozen sections were 92% and 95%, respectively. In the frozen-section technique, the report of the pathologist of the presence or absence of H. pylori gastritis in biopsy specimens could be given to the gastroenterologist by telephone in approximately 20 minutes. CONCLUSIONS: The frozen-section technique is a reliable and rapid method for the diagnosis of H. pylori and provides possibilities for perendoscopic diagnosis of the infection in the hospitals where the frozen-section service is available.

Helicobacter pylori-negative duodenal and pyloric ulcer: role of NSAIDs.

To investigate the frequency of use of nonsteroidal anti-inflammatory drugs (NSAID) in duodenal or pyloric ulcer patients who do not have Helicobacter pylori gastritis, we retrospectively analyzed the use of these drugs among 16 patients who had an endoscopically diagnosed duodenal or pyloric ulcer but had a histologically normal and noninfected stomach, and compared this frequency of use of NSAIDs with that in three control groups. The 16 patients are a consecutive subgroup (2.3%) from 707 patients who were endoscopically diagnosed as having duodenal or pyloric ulcer in Jorvi Hospital during 1985-1994. In all 16 patients, endoscopical and clinical appearances of the ulcers were seen by the clinician similar to those in ordinary peptic ulcer disease. The ulcers occurred at the same site in the duodenal bulb and pylorus as the ordinary peptic ulcers but tended to bleed more often: endoscopy was done more frequently among the 16 gastritis-negative patients because of ulcer bleeding than among the controls. Thirteen of the 16 patients (81%; CI95: 62-100%) did use NSAIDs. This frequency was higher (p < 0.05) than the corresponding frequency of the use of NSAIDs in any of the three control groups, i.e. (a) H. pylori-positive duodenal or pyloric ulcer patients [16 of 39 (41%)], (b) H. pylori-negative nonulcer patients [11 of 64 (17%)] or (c) H. pylori-positive nonulcer patients [14 of 42 (33%)]. We conclude that the history of use of NSAIDs is more common in duodenal and pyloric ulcer patients who have a normal, noninfected stomach than the history of use of NSAIDs in those in whom the ulcer is associated with H. pylori gastritis.
