Evaluation of long-term function, complications, quality of life and health status after restorative proctocolectomy with ileo neo rectal and with ileal pouch anal anastomosis for ulcerative colitis.

AIM: Restorative surgery after (procto)colectomy with ileo-neorectal anastomosis (INRA) or restorative proctocolectomy with ileal pouch anal anastomosis (RPC) combines cure of ulcerative colitis (UC) with restoration of intestinal continuity. This study aimed to evaluate these two operations. METHOD: Patients having INRA and RPC were matched according to sex, age at onset of UC, age at restorative surgery and duration of follow-up. Patients were included if they were over 18 years of age, had UC confirmed histopathologically and had undergone either operation. Long-term function, anal and neorectal physiology, complications, quality of life (QoL) and health status (HS) were determined. RESULTS: Seventy-one consecutive patients underwent surgery with the intention of having an INRA procedure. This was successfully carried out in 50, and 21 underwent intra-operative conversion to RPC. Median defaecation frequency was 6/24 h. In 11/71 patients reservoir failure occurred and 13/71 developed pouchitis. QoL and HS were comparable to the healthy population. Median follow-up was 6.2 years. These patients were matched with 71 patients who underwent RPC. RPC was successful in all patients. Median defaecation frequency was 8/24 h. Failure occurred in 7/71 patients and 13/71 developed pouchitis. QoL and HS were comparable with the healthy population. Median follow-up was 6.9 years. CONCLUSION: Comparison of INRA and RPC on an intention to treat basis was not considered to be realistic due to the high intra-operative conversion rate and the failures in the INRA group. RPC remains the procedure of choice for restoring intestinal continuity after proctocolectomy for UC.

The ileo neo-rectal anastomosis in patients with familial adenomatous polyposis: a prospective case series with long-term follow up.

AIM: In patients with familial adenomatous polyposis (FAP), removal of the colonic mucosa is essential to reduce the lifetime risk of developing cancer). For this purpose, ileo-pouch anal anastomosis (IPAA) has been the gold standard, but morbidity related to the dissection of the pelvis remains substantial. In an attempt to reduce the procedure-related complications of pelvic dissection, ileoneo-rectal anastomosis (INRA) has been developed. In this case series of FAP patients, the long-term functional results, morbidity and quality of life (QoL) of the INRA procedure were evaluated and compared with its early outcome. METHOD: Long-term follow up of a consecutive group of eight FAP patients with an INRA procedure (between 1998 and 2005) was undertaken. Data on functional results, complications, manometry and endoscopy were recorded prospectively. RESULTS: Eight patients with FAP underwent the INRA procedure. The median number of defaecations over 24 h was five. No pelvic sepsis or bladder dysfunction occurred. One patient, in whom concomitant Crohn's disease was diagnosed in retrospect, was converted to IPAA. In the INRA patients, no sexual dysfunction occurred. Endoscopic examination showed normal mucosa without any evidence of polyp formation. CONCLUSION: Restorative surgery by means of the INRA procedure yields good functional results in FAP patients, without any pelvic dissection-related morbidity or regrowth of polyps in the neo-rectum.

Quality of life, health-related quality of life and health status in patients having restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: a systematic review.

AIM: There are numerous studies on quality of life (QoL), health-related quality of life (HRQoL), and health status (HS) in patients undergoing surgery for ulcerative colitis. A systematic review of published literature was conducted to establish the quality of these studies and to determine QoL, HRQoL, and HS in patients after ileal pouch-anal anastomosis for ulcerative colitis. METHOD: All published studies describing QoL, HRQoL, and HS in adult patients in combination with ileal pouch-anal anastomosis for ulcerative colitis were reviewed systematically. No time or language limitations were applied. Relevance was established on the basis of three pre-specified selection criteria: 1) ileal pouch-anal anastomosis was performed for ulcerative colitis, 2) QoL, HRQoL, and HS were reported as outcome of the study and 3) studies reported a minimum follow-up after surgery for 12 months. Outcome variables were results of QoL, HRQoL, and HS, characteristics of the study population, pouch construction, duration of follow-up, and time of assessment in months before and after restorative surgery. Descriptive data synthesis was performed by tabulation displaying the methodological quality, study characteristics and conclusions on QoL, HRQoL, and HS measurements in the studies. RESULTS: The review included 33 studies comprising 4790 patients. Three were graded to be of high quality, 23 of moderate quality and seven of low quality. All reported improved HS and the majority reported improved HRQoL. However, none of the studies reported on QoL. CONCLUSION: The HRQoL and HS of patients with ulcerative colitis improved 12 months after restorative proctocolectomy with an ileal pouch-anal anastomosis and were indistinguishable from the HRQoL and HS of the normal healthy population.

Quality of life and health status before and after ileal pouch-anal anastomosis for ulcerative colitis.

BACKGROUND: Ileal pouch-anal anastomosis (IPAA) is considered the surgical treatment of choice for patients with ulcerative colitis. Quality of life (QoL) and health status are the most important patient-related outcomes. Studies investigating QoL are often cross-sectional and focus on health status. This longitudinal study evaluated QoL and health status after IPAA for ulcerative colitis and compared these with reference data from a healthy population. METHODS: Patients with ulcerative colitis who underwent a pouch operation between 2003 and 2008 completed validated questionnaires for QoL and health status. Questionnaires were completed before pouch surgery, and 6, 12, 24 and 36 months after operation. The effect of IPAA on QoL and health status was analysed, and data were compared with reference values from the healthy Dutch population. RESULTS: Data were obtained for 30 of the 32 patients. Six months after IPAA, QoL was at least comparable with that of the reference population in four of six domains. Twelve months after IPAA, overall QoL had improved, supported by findings in three QoL domains. Six months after IPAA, health status was comparable to that of the reference population in three of eight dimensions, and after 3 years it was at least comparable in five dimensions. CONCLUSION: QoL and health status increased after IPAA and reached levels comparable with those of the healthy reference population in a majority of domains and dimensions. QoL was restored first after IPAA, followed by health status.

Saphenous vein spiral graft: successful emergency repair of a mycotic aneurysm with aortoduodenal fistula.

Mycotic aneurysms leading to aortoduodenal fistula (ADF) are associated with high morbidity and mortality. We report a patient with a mycotic aneurysm and ADF who required emergency laparotomy. After excision of the aneurysm, vascular reconstruction was performed using an autologous graft. The left long saphenous vein was harvested and constructed into a spiral graft. The graft was inserted using a standard inlay technique. After 12 months the patient is in good health. No inflammation or dilation of the saphenous vein spiral graft has been noted. We suggest that in the emergency treatment of mycotic abdominal aneurysm, aortic reconstruction with saphenous vein spiral graft is a valuable option.

Metformin and lactic acidosis: cause or coincidence? A review of case reports.

OBJECTIVE: Metformin has been associated with the serious side-effect lactic acidosis. However, it remains unclear whether the use of metformin was a cause or a coincidence in lactic acidosis. DESIGN: A literature search of the Index Medicus (1959-66) and of the databases Embase, Medline, Medline Express (1966-99) was performed using the keywords metformin, biguanides and lactic acidosis. All articles of cases with metformin-induced lactic acidosis (MILA) were cross-referenced. SUBJECTS: Cases were included for analysis if they met the following criteria: serum pH < or =7.35, lactate concentration > or =5 mmol L(-1). INTERVENTION: A forum of six experts in intensive care medicine independently categorized the cases in MILA unlikely (score 0), possible MILA (score 1) or probable MILA (score 2). MAIN OUTCOME MEASURES: Statistical analysis included the paired interobserver agreement (kappa) and multivariate regression analysis. RESULTS: Of 80 reported cases, 33 were excluded because of insufficient quality. The forum scores of the remaining 47 cases were distributed normally with a mean score of 7 (range 2-10). The kappa-value was 0.041 (SD = 0.24, range -0.514, 0.427). Neither lactate concentration nor mortality correlated with serum metformin concentrations. CONCLUSIONS: Given the low interobserver agreement and the lack of any relationship between metformin levels and outcome parameters, the concept that there is a simple, causal relationship between metformin use and lactic acidosis in diabetic patients has to be reconsidered.

Effect of metformin on glycaemic control in type 2 diabetes in daily practice: a retrospective study.

INTRODUCTION: Recently the UKPDS study revealed the potency of metformin therapy in obese type 2 diabetic patients. A retrospective study was performed to assess the efficacy of metformin therapy in improving metabolic control in everyday practice. PATIENTS AND METHODS: Type 2 diabetic patients were included if they met the following criteria: metformin had been added when the previous treatment failed to optimise glycaemic control expressed in HbA1c level; duration of metformin therapy had to be at least six months. Efficacy of metformin therapy, expressed as a decrease in HbA1c, was measured with a median follow-up of 32 (range 6-60) months. Variables were analysed using a paired t-test. RESULTS: One hundred and sixty-three patients were treated with metformin. 98 patients were excluded, because of absence of an HbA1c value prior to treatment with metformin mainly (n = 78). The mean HbA1c of included patients had decreased 1.4% (p < 0.001) after 6 months (n = 65), 1.6% (p < 0.001) after 24 months (n = 45) and 1.5 (p < 0.001) after 36 months (n = 28). During follow-up there was no significant weight gain or loss. CONCLUSION: Metformin can be considered an effective treatment to improve glycaemic control in obese type 2 diabetic patients.
