Stapled ileoanal pouches without loop ileostomy: a prospective study in 86 patients.

In restorative proctocolectomy the use of a stapling technique to construct an ileal pouch with anal anastomosis offers an alternative to the hand-sewn technique following mucosectomy; a temporary defunctioning loop ileostomy may reduce the consequences of an anastomotic leakage, however it may entail discomfort for the patient, an additional operation, possible complications, and longer total hospital stay. This prospective study evaluated the peri- and postoperative courses in 86 consecutive, referred patients receiving ileal pouch-anal anastomosis using the stapling technique to construct the ileal pouch and ileoanal anastomosis, omitting the defunctioning loop ileostomy except in cases of increased risk of ileoanal anastomotic insufficiency according to defined criteria. Follow-up time was 36-96 months. Patients undergoing primary loop ileostomy stayed a median of 19 days in hospital, as opposed to a median of 9 days in those who did not. Eight patients developed pelvic sepsis that demanded a secondary defunctioning loop ileostomy, and five showed symptoms arising from relapsing inflammation in residual rectal mucosa; in three of these, a secondary transanal mucosectomy covered by a loop ileostomy was necessary. During the follow-up period ten patients had bowel obstructions that demanded surgery; two developed late pouch-vaginal fistulas, and one a fistula from the J-limb to the abdominal scar. There was one case of pouch procidentia. At 12-month follow-up the median evacuation frequency was 6 per 24 h, the incidence of minor incontinence was about 10%, and urgency to evacuate occurred in about 10%. None of the patients experienced any major incontinence. The stapling technique and omission of the defunctioning loop ileostomy in restorative proctocolectomy were thus a comparatively reliable and time-saving method with short total hospital stay. In patients at increased risk of anastomotic complications, however, a defunctioning loop ileostomy is recommended. We believe it is important to perform an exact dissection into the anal canal to avoid a residual rectal mucosa that may be inflamed or even become dysplastic.

A study of plasma immunoglobulins profile in connection with restorative proctocolectomy.

BACKGROUND: Restorative proctocolectomy is an operative procedure that in principle means proctocolectomy, preserving the anal sphincters and construction of an ileal pouch which is sutured to the dentate line. The method is used mostly in case of surgical treatment of ulcerative colitis or familial polyposis coli. The procedure means different manipulations with the distal ileum that may influence the function of gut-associated lymphoid tissues, a major subdivision of the immune system. AIM: The aim of the present investigation was to study the plasma concentration of immunoglobulins in connection with the restorative proctocolectomy operation. METHODS: Forty five patients received an ileoanal pouch (IAP) because of ulcerative colitis. Twenty seven patients were males and 18 females. The mean age was 34 (range 18-55) years. Twenty six patients were first operated on emergency by subtotal colectomy with terminal ileostomy. In a second operation, the rectum was excised and an ileoanal pouch and a loop ileostomy that diverted the bowel content from the distal ileum was performed. Eighteen elective patients had their colectomy performed at the same time as the pouch operation. As a last procedure the diverting loop ileostomy was closed and thereby the distal ileum and the ileoanal pouch was put into function. Blood samples for plasma immunoglobulin analyses was collected from the patients before the colectomy, after colectomy with terminal ileostomy before construction of the pouch, during the period with pouches prior to loop ileostomy closure and 12 months after its closure. Immunoglobulins in plasma were determined by nephelometry method. The data was analyzed statistically by ANOVA and linear regression analysis. RESULTS: There was a significant difference preoperatively, in plasma immunoglobulin G (P-IgG) between the patients who were operated on electively compared to the emergency patients (p < 0.03). This was the only significant difference between values for the emergency and elective groups throughout the study. In the emergency patients after colectomy and with terminal ileostomy plasma immunoglobulin A (P-IgA) and immunoglobulin A (P-IgM) concentrations in plasma had increased significantly compared to preoperative (p < 0.03) and (p < 0.002) respectively. During the time with loop ileostomy plasma IgM was still found to be significantly elevated (p < 0.02) compared to the level before colectomy. In the electively operated patients plasma IgA and IgM were significantly increased after colectomy and pouch construction during the time with loop ileostomy compared to preoperatively (p < 0.04) and (p < 0.0004). After 12 months with functional pouches the plasma immunoglobulins in both groups were similar to the elective patients preoperatively. CONCLUSION: The immunoglobulins IgG, IgA and IgM were studied in connection with restorative proctocolectomy. Preoperatively, IgG was found to be significantly lower in emergency compared to elective patients. The difference is probably due to increased losses and impaired production of IgG in the acute phase of ulcerative colitis. IgA and IgM were found to increase significantly after colectomy and construction of an ileostomy but how these measures were responsible for the changes could not be determined in the present study. Twelve months after loop ileostomy closure there were no longer any significant changes of the immunoglobulins compared to elective patients with ulcerative colitis preoperatively.

Observations in the blood lipid profile in patients undergoing restorative proctocolectomy.

BACKGROUND: Ileal dysfunction, and resection or exclusion may affect intestinal bile acid resorption resulting in alterations in serum lipid concentration. In restorative proctocolectomy, the different procedures may involve the ileum in all three ways. AIM: The aim of the present study was to analyse possible changes of the blood lipid profile during the different steps of restorative proctocolectomy operative procedure. METHOD: There were nineteen elective patients on their ordinary diet and 19 emergency patients on total parenteral nutrition. The former group were primarily operated on with colectomy; ileoanal pouch and loop ileostomy while the later group had had an emergency colectomy and terminal ileostomy before the pouch operation. Thirty five of the patients had ulcerative colitis, 2 had familial colon polyposis and 1 familial cancer syndrome. Blood specimens were collected in the mornings with the patients in a fasting state. The emergency patients were on unchanged ordinary diet during the preoperative period. Serum cholesterol and triglyceride were determined by enzymatic methods. Lipoproteins, studied only in the elective patients, were analysed by a combination of ultracentrifugation and precipitation. Student's t-test with Bonferroni's correction for multiple comparisons was used for statistic calculations. RESULTS: Preoperatively, the emergency group had significantly lower serum cholesterol but not serum triglycerides values compared to the elective group. This finding is probably due to difference in the preoperative nutrition. The cholesterol levels among patients who received steroids in the two groups were compared and found to be significantly lower in the emergency group. Later, no significant differences concerning cholesterol and triglycerides were found between the groups. The cholesterol level was not significantly different in the elective group between patients who receive hydrocortisone and those who did not. During the period with loop ileostomy cholesterol was significantly lowered while the triglycerides were significantly increased compared to the preoperative values of the elective group. The decrease of serum cholesterol levels was correlated to the length of the excluded ileum. During the same period alpha-lipoprotein decreased significantly and reached values below the normal of the reference material. Beta-lipoproteins, which were subnormal already preoperatively, increased but not significantly. Pre-beta-lipoproteins were at the same level at all stations. At 12 months with functioning pouches all analysed values, with the exception of beta-lipoproteins. were within the normal limits set by the reference material. In the emergency group the patterns for triglycerides and cholesterol were similar but for the preoperatively depressed cholesterol values. After 12 months with functioning pouch the serum cholesterol and triglycerides were at the same level as for the elective patients. CONCLUSION: A serum lipid profile was studied in patients undergoing restorative proctocolectomy. Serum cholesterol and alpha-lipoprotein decreased and triglycerides increased when the patients had a diverting loop ileostomy. At 12 months after it's closure and with a functioning pouch, the patients had the same profile as the elective patients preoperatively, and with exception of beta-lipoproteins within normal limits in spite of the loss of the colon and the construction of a pouch of the distal ileum.

Effect of restorative proctocolectomy on gastric acid secretion and serum gastrin levels: a prospective study.

PURPOSE: The aim of the present study was to analyze gastric acid secretion after restorative proctocolectomy, because it has been shown that ileal resection or exclusion may increase gastric acid secretion. An increased output of gastric acids may decrease the intestinal passage time and contribute to looser stools. METHODS: Eleven patients who had elective colectomy and ileoanal pouch because of ulcerative colitis were investigated. Eight patient were males. Eight S-pouches and three J-pouches were constructed. Gastric acid secretion (retention, basic, and stimulated) was studied, together with serum gastrin, pentagastrin, and pepsinogen, in patients before colectomy and after having had the pelvic pouch functioning for 12 months. RESULTS: A significant increase, compared with preoperative levels, in retention, basic, and stimulated gastric acid secretion was found after 12 months with the pouch functioning. Levels of serum gastrin, pentagastrin, and pepsinogen were unchanged. CONCLUSION: Restorative proctocolectomy leads to a significant increase in gastric acid secretion. These findings may be of importance with regard to intestinal passage time and consistency of the stools.

Gains and losses with stapling and omission of loop ileostomy in pelvic pouch surgery: a matched control study.

After 10 years experience of pelvic pouch surgery with handsewn pouch and ileoanal anastomosis, mucosectomy, and covering loop ileostomy, the surgical technique was altered. Twenty patients were operated on with staple technique in pouch and ileoanal anastomosis but without mucosal proctectomy and loop ileostomy. This study group was compared with a matched control group of patients from our previous series with respect to duration of surgery, blood loss, hospital stay, complications, and functional outcome after 2 months, 12 months, and 60 months. It was found that staple technique significantly reduced the duration of surgery and the need of blood transfusions. Length of hospital stay after pouch surgery did not differ between the two groups, but omitting loop ileostomy reduced total hospital stay by about 2 weeks. Ileoanal anastomotic insufficiency occurred in two patients in the study group. Treatment by establishment of a defunctioning loop ileostomy, local saline perfusion, and administration of antibiotics was successful; the anastomosis healed within 2 weeks, and the longterm functional outcome did not differ from the average. Increased temperature persisted postoperatively in seven patients in the study group. Transient peroneal paresis occurred in three patients in the control group. Only in the control group was there stenosis in the ileoanal anastomosis requiring dilatation and fibrosis at the levator plane demanding emptying by a catheter. Concerning functional outcome, nighttime continence was significantly better in the study group than in the control group. The evacuation rate per 24 h was significantly higher in the study group after 2 and 12 months but not after 60 months. The outcome concerning other functional parameters such as urgency to evacuate, capacity to discriminate between gas and stool, deferral time, and perianal symptoms, did not differ significantly. Staple technique without mucosal proctectomy and loop ileostomy thus results in shorter duration of surgery and shorter hospital stay. In patients with increased risk of insufficiency of the anastomosis, however, covering loop ileostomy may be justified because of the risk for more serious consequences if anastomotic leakage occurs.

A prospective study of personality as a predictor of quality of life after pelvic pouch surgery.

BACKGROUND: Surgeons often "know" preoperatively which patients will achieve good postoperative quality of life (QOL). This intuition is probably based on impressions of the patient's personality. The present aim was to examine whether preoperative personality traits predict postoperative QOL. METHODS: In 53 patients undergoing pelvic pouch surgery for ulcerative colitis the relationship between preoperative personality traits, and surgical functional outcome and QOL was examined at a median of 17 months postoperatively. Personality assessment instruments (KAPP and KSP), and specific measures of alexithymia were used. Postoperatively, the Psychosocial Adjustment to Illness Scale (PAIS), and surgical functional outcome scales were used. RESULTS: Using multiple correlation/regression, analysis lack of alexithymia, poor frustration tolerance, anxiety proneness, and poor socialization (resentment over childhood and present life situation) were found to predict poor postoperative QOL. CONCLUSIONS: The findings suggest personality traits, in addition to surgical functional outcome, to be important for the patient's postoperative QOL.

Neoplastic transformation of the pelvic pouch mucosa in patients with ulcerative colitis.

BACKGROUND & AIMS: Some patients with ulcerative colitis (UC) receiving an ileal pelvic pouch with ileoanal anastomosis (IPAA) develop persistent severe villous atrophy in the pouch mucosa. To investigate if mucosal atrophy indicates a risk for subsequent neoplastic transformation of the ileal pouch mucosa, a follow-up study was undertaken. METHODS: Seven patients with UC and an IPAA in whom persistent severe atrophy (type C) developed and 14 control patients with no or only slight atrophy (type A) were prospectively surveyed by flexible videoendoscopy with multiple biopsies for assessment of possible neoplastic changes. RESULTS: The median time of the pouch in function was 9 years for both groups. Dysplasia was found in 5 of 7 patients in the type C group (71%) compared with none in the type A group (P < 0.001). Four patients had low-grade dysplasia, and 1 patient had sequential multifocal development into high-grade dysplasia. Multifocal DNA aneuploidy was found in 2 patients, 1 with low-grade and 1 with high-grade dysplasia. CONCLUSIONS: Patients with UC and a long-standing IPAA who develop persistent severe mucosal atrophy are at risk also of neoplastic transformation of the pouch mucosa.

Pouchitis following pelvic pouch operation for ulcerative colitis. Incidence, cumulative risk, and risk factors.

AIM: This study was undertaken to assess the risk for pouchitis in patients with ulcerative colitis who underwent surgery with colectomy, restorative pelvic pouch, and ileoanal anastomosis and to evaluate possible factors predictive for pouchitis development. PATIENTS AND METHODS: All patients receiving a pelvic pouch because of ulcerative colitis at Huddinge University Hospital between 1980 and 1993 (n = 149; 89 men) were prospectively evaluated for symptoms suggestive of pouchitis. Diagnosis of pouchitis was based on occurrence of certain symptoms in combination with endoscopic findings. Pouchitis was divided into mild and severe, and the time span until the first attack of mild or severe pouchitis was calculated for each patient. RESULTS: Median follow-up time was 54 (5-152) months. The absolute cumulative risk of developing mild pouchitis was 21, 26, and 39 percent at 6, 12, and 48 months, respectively. The corresponding cumulative risk of developing severe pouchitis was 9, 11, and 14 percent, respectively. Risk for both groups together was 51 percent at 48 months. The occurrence of pouchitis, calculated at six-month intervals after closure of the loop ileostomy, was highest (23.1 percent) during the first six months. Incidence during the next six-month period was 11.4 percent and then only 3.1 percent thereafter. Thirty-two patients (21.5 percent) had chronic continuous symptoms requiring long-term metronidazole treatment, and 14 (9.4 percent) of those had chronic severe pouchitis. In two patients, removal of the pouch and permanent ileostomy became necessary. Extracolonic manifestations and early onset of ulcerative colitis were predictive factors for developing pouchitis. Former smoking seemed to be a protective factor. CONCLUSION: The risk for pouchitis was highest during the initial six-month period. Cumulative risk leveled off after two years but was substantial (51 percent) at four years. Less than 10 percent of patients had severe, chronic pouchitis, and only two patients (1.3 percent) had their pouches removed.

Ileoanal anastomosis with pelvic pouch: short review.

Pelvic pouch surgery is still a rather new technique, but has been developed considerably over the years. The construction of J-shaped pouches and ileoanal anastomoses with a total stapling technique has meant considerable progress in the operative procedure compared to the method including mucosal proctectomy en bloc with excision of the rectum and colon, handsewn pouches, and handsewn ileoanal anastomoses. Omission of a deviating loop ileostomy saves the patient another operation, hospital stay and sick leave. Development of malignancy in an atrophic pouch mucosa cannot be ruled out. Careful surveillance of all patients at the operating clinic is therefore necessary.

Long-term histomorphological surveillance of the pelvic ileal pouch: dysplasia develops in a subgroup of patients.

BACKGROUND & AIMS: Little is known about the long-term morphology of the pelvic ileal pouch after restorative proctocolectomy in patients with ulcerative colitis. This study analyzed the mucosal adaptation in the pouch during a long-term follow-up. METHODS: Mucosal biopsy specimens were obtained from 87 patients during a follow-up of 6.3 years (SD, 2.7; range, 3-14 years). The villous surface density, degree of inflammation, and type of mucin were determined from glycolmethacrylate-embedded sections. RESULTS: Three basic patterns of mucosal adaptation were observed: regular response with normal mucosa or mild villous atrophy and no or mild inflammation (type A, 51%), transient atrophy response with temporary moderate or severe villous atrophy followed by normalization of architecture (type B, 40%), and constant atrophy response with permanent subtotal or total villous atrophy developing from the early functioning period accompanied by severe pouchitis (type C, 9%). Low-grade dysplasia occurred in 3 patients with type C response. CONCLUSIONS: In a small group of patients with ulcerative colitis, the mucosa of the pelvic pouch adapts with constant severe villous atrophy accompanied by long-standing pouchitis. This group of patients should be identified and undergo regular endoscopic and histomorphological surveillance because of risk of developing neoplasia in the pouch mucosa.

A prospective study of the quality of life after pelvic pouch operation.

BACKGROUND: For surgeons familiar with pelvic pouch operation, it is disappointing that the patients, although very satisfied to have a pouch instead of an ileostomy, often have difficulty in specifying exactly how their quality of life really has improved. The present study is an attempt to examine this situation. STUDY DESIGN: In 48 patients with ulcerative colitis undergoing pelvic pouch operation, quality of life (QOL) was studied prospectively when the patients had an ileostomy, and at follow-up evaluation at least one year after restitution of anal defecation. The surgeons' evaluation of functional outcome was compared with those of three independent evaluators (the patient, a psychiatrist, and a psychologist). The Psychosocial Adjustment to Illness Scale, the Well-being Profile, the Global Assessment of Function Scale, and surgical evaluation scales were used. RESULTS: As assessed by surgeons using the surgical evaluation scales, functional outcome correlated significantly with most of the assessments of QOL done by the three independent evaluators (the patient, a psychiatrist, and a psychologist). Quality of life did not improve with increasing time, either with an ileostomy or with a functioning pelvic pouch. On most evaluations, there was no further significant improvement in QOL after restitution of anal defecation. CONCLUSIONS: The findings suggest that QOL is already satisfactory after "cure" of the disease, and restitution of normal defecation does not yield much further improvement.

Apparent selective bile acid malabsorption as a consequence of ileal exclusion: effects on bile acid, cholesterol, and lipoprotein metabolism.

A new model has been developed to characterise the effect of a standardised ileal exclusion on bile acid, cholesterol, and lipoprotein metabolism in humans. Twelve patients treated by colectomy and ileostomy for ulcerative colitis were studied on two occasions: firstly with a conventional ileostomy and then three months afterwards with an ileal pouch operation with an ileoanal anastomosis and a protective loop ileostomy, excluding on average 95 cm of the distal ileum. The ileostomy contents were collected during 96 hours and the excretion of bile acids and cholesterol was determined using gas chromatography-mass spectrometry. Fasting blood and duodenal bile samples were collected on two consecutive days. After the exclusion of the distal ileum, both cholic and chenodeoxycholic acid excretion in the ileostomy effluent increased four to five times without any change in cholesterol excretion. Serum concentrations of lathosterol (a marker of cholesterol biosynthesis) and 7 alpha-hydroxycholesterol (a marker for bile acid biosynthesis) were increased several fold. Plasma concentrations of total VLDL triglycerides were also increased whereas the concentrations of total and LDL cholesterol, and apolipoprotein B were decreased. There were no changes in biliary lipid composition or cholesterol saturation of bile. The results show that the exclusion of about 95 cm of distal ileum causes malabsorption of bile acids but apparently not of cholesterol. The bile acid malabsorption leads to increased synthesis of both bile acids and cholesterol in the liver. It is suggested that bile acids can regulate cholesterol synthesis by a mechanism independent of the effect of bile acids on cholesterol absorption. The enhanced demand for cholesterol also leads to a decrease in plasma LDL cholesterol and apolipoprotein B concentrations. The malabsorption of bile acids did not affect biliary lipid composition or cholesterol saturations of VLDL triglycerides.

Biochemical laboratory data in patients before and after restorative proctocolectomy. A study on 83 patients with a follow-up of 36 months.

From 1980 to 1987 ileoanal pouches were made in 83 patients. Specimen for a set of laboratory analyses were taken preoperatively, during the ileostomy and loop ileostomy periods and repeatedly during 36 months of follow-up. Cobalamine absorption and 14C-triolein breath tests were performed preoperatively in electively operated patients and postoperatively in all patients at 12 and 36 months. Low S-Ca was most pronounced preoperatively in patients who were to undergo acute colectomy (53%). Decreased S-Mg was detected in 16-36% at all stations. None had signs or symptoms of hypomagnesemia. Low S-albumin was rarely seen except for preoperatively in acute patients. Increased IgM was found in 40% of the patients during the loop ileostomy phase compared to 6-10% preoperatively. Substantially increased orosomucoid and/or haptoglobin were seen in patients during the functional periods but these increased values could not be correlated to episodes with acute pouchitis. High values of S-ALAT and ALP were much more frequent during the loop ileostomy periods than it was preoperatively and during pouch function. Low S-haemoglobin and/or iron were noticed during the functional period in 3-8% and 10-16%, respectively. Severe anaemia, due to iron deficiency developed in one patient after 2.5 years of pouch function. Preoperatively, slight decreases of S-B12 were found in 13% and impaired cobalamine absorption was revealed in 38% of the electively operated patients. The corresponding figures were 3% and 31% after 12 months and 5% and 36% after 36 months of follow-up, respectively. B12 substitution was given to in all 8 patients during the follow-ups. Lipid absorption was disturbed in 38% preoperatively and in 35% and 41% at 12 and 36 months, postoperatively.

Surgery after colectomy for ulcerative colitis.

The need for surgery after colectomy in patients with ulcerative colitis in Stockholm County over a 30-year period, 1955 to 1984, was investigated. During this time 483 patients were discharged from the hospital after colectomy. The mean period of observation from colectomy was 11.6 years. In 325 (67 percent) of the 483 patients there was need for further surgery (932 surgical procedures) during the period of observation. In 95 (20 percent) patients 115 small intestinal obstructions requiring surgery developed. The 2-year and 15-year cumulative probabilities of a first small intestinal obstruction were 11 percent (confidence intervals [CI] 8-14 percent) and 23 percent (CI 19-27 percent), respectively. In 42 (16 percent) of 255 patients treated by proctocolectomy and ileostomy there was need for 64 ileostomy revisions. The 2-year and 15-year cumulative probabilities of a first ileostomy revision were 9 percent (CI 6-12 percent) and 19 percent (CI 14-24 percent), respectively. Ninety-one Kock's pouches were constructed and a total of 125 revisions of Kock's pouch were performed. The 2-year and 15-year cumulative probabilities of a first Kock's pouch revision were 52 percent (CI 41-63 percent) and 57 percent (CI 46-68 percent), respectively. In 75 patients a pelvic pouch and ileoanal anastomosis was constructed. In 32 patients 73 surgical procedures due to pouch-related dysfunction were performed. Alterations in ileoanal pouch technique and increasing surgical experience has resulted in a markedly decreasing frequency of complications during the last years. There was no need for further surgery in 116 (45 percent) of the 255 patients treated by proctocolectomy and ileostomy, in 31 (34 percent) of the 91 patients with Kock's pouch, in 20 (39 percent) of the 51 patients with ileorectal anastomosis, and in 43 (57 percent) of the 75 patients with pelvic pouch and ileoanal anastomosis (closure of loop ileostomy excluded).

Dysplasia and DNA aneuploidy in a pelvic pouch. Report of a case.

A patient with an 18-year history of ulcerative colitis was operated on with colectomy, mucosal proctectomy, ileoanal anastomosis, and an S-type pelvic pouch due to intractable chronic continuous disease. The patient was followed by endoscopic controls and biopsy sampling from the pouch at regular intervals. A gradual development of severe atrophy in the ileal mucosa was followed by the development of low grade dysplasia. At the most recent endoscopic control, 4 years after the construction of the pouch, biopsies were sampled also for flow cytometric DNA analyses. DNA aneuploidy was detected in a biopsy from the center of the pouch, and a biopsy taken immediately adjacent showed low grade dysplasia. These findings underline the importance of endoscopic follow-up after construction of a pelvic pouch and focus attention to the potential of malignant transformation of the mucosa.
