Laparoscopic total colectomy for colorectal cancers: a comparative study.

BACKGROUND: No previous report could be found in the literature comparing laparoscopic and open total colectomy for colorectal cancers, especially synchronous colorectal cancers. This study aimed to compare the short-term clinical outcomes and oncologic results of laparoscopic and open total colectomy or proctocolectomy for colorectal cancers. METHODS: Between July 1997 and January 2005, six patients with colorectal cancers underwent elective laparoscopic total colectomy or proctocolectomy at the authors' institution. Clinical data for 12 patients who underwent elective open total colectomy or proctocolectomy for colorectal cancers during the same period were prospectively collected and compared. RESULTS: The median follow-up periods were 43.9 months for the laparoscopic group and 48.2 months for the open group. Conversion to open procedure was required for one patient (16.7%) in the laparoscopic group because of bleeding. The median operative time was significantly longer in the laparoscopic group (427.5 min; range, 280-480 min vs 172.5 min; range, 90-260 min; p = 0.001). The patients in the laparoscopic group required a significantly shorter duration of parenteral analgesia (3 vs 5 days; p = 0.01), but there were no differences in time to first bowel motion, time to resumption of diet, time to full ambulation, and duration of hospital stay between the two groups. Perioperative morbidity rates were comparable between the two groups, and there was no operative mortality. The oncologic results, including number of lymph nodes removed, recurrence rates, and survival rates, were similar in the two groups. CONCLUSIONS: Laparoscopic total colectomy has short-term clinical outcomes (postoperative recovery and perioperative morbidity and mortality rates) and oncologic results similar to those of open surgery for treating patients with colorectal cancers. Our study has shown that the only advantage of laparoscopic over open surgery is a shorter duration of analgesic requirement, but at the expense of a longer operative time.

Does a laparoscopic approach to total abdominal colectomy and proctocolectomy offer advantages?

BACKGROUND: Controversy exists regarding the feasibility, safety, and outcomes of laparoscopic total abdominal colectomy (LTAC) and laparoscopic total proctocolectomy (LTPC). The object of this study was to assess the outcomes of LTAC and LTPC and compare them with those of institutional open procedure used as controls. METHODS: Perioperative data and surgical outcomes of patients who underwent TAC or TPC were analyzed and compared retrospectively at a single institution between 1991 and 1999. RESULTS: A total of 73 TACs performed during a 9-year period were evenly distributed between laparoscopic (n = 37) and open (n = 36) approaches. There were no significant differences between patient groups with respect to genders, age, weight, proportion of patients with inflammatory bowel disease, and the number of patients undergoing ileorectal anastomosis. The median operative time was longer with the laparoscopic method (270 vs 178 min; p = 0.001), but the median length of hospital stay was significantly shorter (6 vs 9 days; p = 0.001). The short-term postoperative complication rate up to 30 days from surgery was not statistically different (25% vs 44%; p = 0.137), although there was a clear trend toward a reduced number of overall complications in the laparoscopic group (9 vs 24). Wound complications were significantly fewer (0% vs 19%; p = 0.015) and postoperative pneumonia was nonexistent in laparoscopic patients. Long-term complications also were less common in the laparoscopic group (20% vs 64%; p = 0.002), largely because of reduced incidence of impotence, incisional hernia, and ileostomy complications. Total proctocolectomy was performed laparoscopically in 15 patients and with an open procedure in 13 patients over the same period. There were no statistically significant differences between the two groups with respect to gender, age, weight, and diagnosis. Median operating time was longer for the laparoscopic patients (400 vs 235 min; p = 0.001), whereas the length of hospital stay, morbidity, and mortality were not significantly different. CONCLUSIONS: The results indicate that LTAC can be performed safely with a statistically significant reduction in wound and long-term postoperative complications, as compared with its open counterpart. Operating time is increased, but there is a marked reduction in length of hospital stay. Preliminary results demonstrate that LTPC also is technically feasible and safe, with equal morbidity, mortality, and hospital stay, as compared with open procedures. Studies with larger numbers of patients and a randomized controlled trial giving special attention to patient quality-of-life issues are needed to elucidate the real advantages of this minimally invasive technique.

Management of obliterating stricture after coloanal anastomosis.

We present an unconventional approach to the management of a severe stricture with complete luminal obliteration after a coloanal anastomosis which was protected with a diverting loop ileostomy. The colonoscope was inserted in an antegrade fashion into the defunctionalized limb of the loop ileostomy and advanced to the level of the stricture. Under colonoscopic vision, a Kelly clamp was carefully introduced transanally through the stricture into the proximal lumen. The strictured anastomosis was then dilated with calibrated Hegar dilators. Periodic dilatations followed by closure of the ileostomy completed the management. The technique obviated the need for a more extensive surgical procedure.

Assessment of the Japanese Inflammatory Bowel Disease Questionnaire in patients after ileal pouch anal anastomosis for ulcerative colitis.

BACKGROUND: The Inflammatory Bowel Disease Questionnaire (IBDQ) is the most widely used disease-specific health-related quality of life questionnaire for patients with inflammatory bowel disease. However, little has been reported about the validation of IBDQ for patients with ulcerative colitis after surgery. The aim of this study was to assess the validity and reliability of the Japanese version of IBDQ in patients with ulcerative colitis after total proctocolectomy and ileal pouch anal anastomosis (IPAA). METHODS: The validity and reliability of the Japanese IBDQ were assessed in patients with ulcerative colitis who had received IPAA in our hospital. We mailed them the Japanese IBDQ and a supplemental questionnaire on bowel function, which was developed at our institution. Internal consistency, discriminative validity, and factor validity were assessed. RESULTS: Of the 121 patients to whom we sent the questionnaires, 64 patients (53%) participated in this study. The Japanese IBDQ scores correlated well with Cronbach's alpha value (0.800 to 0.923) and daily life satisfaction score (Pearson's r, 0.492 to 0.700). The total IBDQ score and two subscale scores of the IBDQ, "bowel symptoms" and "systemic symptoms," correlated well with daily bowel-movement frequency (Pearson's r, -0.256 to -0.329). Factor analysis revealed a four-factor structure, and all correlations among factors were moderately positive (0.337 to 0.465). Although the factor distribution was not clearly divided into the four IBDQ subscales, these four factors showed a marked tendency to represent the IBDQ subscales independently. CONCLUSIONS: The Japanese IBDQ is a valid and reliable instrument for the assessment of Japanese patients with ulcerative colitis after IPAA.

Leukocyte removal therapy for ulcerative colitis does not affect postoperative complications.

BACKGROUND: We investigated the incidence of postoperative complications in patients treated with or without preoperative leukocyte removal therapy (LRT). METHODS: The case notes of 387 patients with ulcerative colitis (UC) who underwent surgical intervention were retrospectively reviewed. One hundred nine patients were treated with LRT within 8 weeks before surgery (LRT group), and 278 had not received LRT since at least 8 weeks before surgery (without LRT group). We reviewed the postoperative complications according to type of initial operation. RESULTS: Of the patients who underwent an ileal J-pouch anal anastomosis (IPAA) without an ileostomy, 3 (6.5%) in the LRT group developed pouch-related complications (PRC), while 11 (7.5%) in the without LRT group developed PRC. The overall postoperative complication rates were 28.3% in the LRT group and 21.8% in the without LRT group. For patients who underwent an IPAA with an ileostomy, the overall rates of postoperative complications were 39.1% in the LRT group and 31.8% in the without LRT group. Among those undergoing a total colectomy, 33.3% in the LRT group and 18.2% in the without LRT group had postoperative complications. No statistically significant differences were demonstrated between the two groups with respect to postoperative complications. CONCLUSIONS: Our results suggest that preoperative LRT does not influence the rate of postoperative complications in UC patients.

Progression of primary biliary cirrhosis after proctocolectomy for ulcerative colitis.

We report a case of progression of primary biliary cirrhosis (PBC) after proctocolectomy for ulcerative colitis. A 43-year-old woman underwent a total proctocolectomy after being diagnosed with ulcerative colitis. In the course of the preoperative investigation, liver function test results were within the normal range. Four months after the proctocolectomy, the patient showed a high level of alkaline phosphatase (2398 IU/l) and a positive anti-mitochondrial antibody titer (>1:160). There were no associated symptoms. A liver biopsy demonstrated expansion of all portal areas by infiltrates of lymphocytes and histiocytes. These appearances indicated chronic biliary disease and were compatible with PBC. The association of PBC and ulcerative colitis is rare. However, a review of the recent literature suggests that PBC and ulcerative colitis may be associated; this combination should be kept in mind.

Refractory ulcerative colitis complicated by a cytomegaloviral infection requiring surgery: report of a case.

Cytomegalovirus (CMV) infection has been reported to be a cause of refractory ulcerative colitis (UC). We herein report a case of refractory ulcerative colitis complicated by CMV infection requiring surgery. A 22-year-old man was admitted to our hospital with lower abdominal pain and bloody diarrhea. Under a diagnosis of acute UC, he was treated with prednisone 60 mg/day and sulfasalazine. Since his symptoms appeared to improve, the prednisone dosage was gradually reduced to 20 mg/day. After 5 months, he had an unexpected flare-up with fever and fresh anal bleeding. Colonoscopy demonstrated a punched out ulcer in the sigmoid colon. Biopsies by colonoscopy revealed cytomegalic inclusion bodies. Serologic and immunologic studies also suggested a recent CMV infection. Under a diagnosis of intractable UC complicated by a CMV infection, ganciclovir therapy was carried out, and the steroid therapy was tapered. Although the serum antigenemia became negative after the antiviral therapy, follow-up colonoscopy confirmed the severe stenosis after the punched-out ulcer healed completely. Since his symptoms did not improve, it was necessary to perform an elective proctocolectomy despite antiviral therapy. He was discharged with an uneventful postoperative course. It is important to recognize CMV colitis as a complication of inflammatory bowel disease, particularly in severe steroid-resistant colitis. Furthermore, in cases which fail to respond to antiviral treatment, the patient may ultimately require surgery.

Anal function during pregnancy and postpartum after ileal pouch anal anastomosis for ulcerative colitis.

PURPOSE: Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is now a common procedure for ulcerative colitis (UC). Moreover, it has been reported that fertility is preserved in women who undergo this procedure, many of whom can experience normal delivery. METHODS: We assessed the perinatal outcomes and changes in anal function in four women, aged from 27 to 35 years, who gave birth after undergoing IPAA for UC. Pregnancies were confirmed 15-111 months after IPAA, three women had full-term pregnancies, and one gave birth after 31 weeks' gestation. RESULTS: Cephalic delivery with a vacuum extractor was used for one patient, and another underwent cesarean section. The other two patients experienced normal delivery. None of the patients needed artificial insemination and none had any symptoms of intestinal obstruction during their pregnancy. After delivery, two patients suffered a transient increase in bowel frequency and soiling, which gradually resolved. CONCLUSIONS: Although transient anal dysfunction occurred in the puerperal period, there were no changes in anal function during pregnancy. Therefore, there are no factors directly prohibiting pregnancy and vaginal delivery in women who undergo IPAA for UC.

Renal expression of the essential genes associated with sodium transport following a total proctocolectomy in rats.

The water and electrolyte balance is regulated by the renin-angiotensin-aldosterone system in the kidney. We previously reported that the levels of circulating aldosterone dramatically increased following a total proctocolectomy in rats. However, there is no direct evidence regarding whether renal adaptation is accelerated by the induction of aldosterone-associated molecules. To explore this question, Sprague-Dawley rats underwent total proctocolectomies and then were killed 8 weeks later. We investigated the renal expression of 11beta-hydroxysteroid dehydrogenase type 2, the alpha-, beta-, and gamma-subunits of the epithelial sodium channel, and the alpha1- and beta1-subunits of Na+,K+-ATPase mRNAs because those molecules are responsible for the aldosterone specificity for mineralocorticoid receptor, amiloride-sensitive sodium absorption, and sodium extrusion from distal tubules, respectively. A Northern blot analysis demonstrated the kidney to exhibit mRNA induction for all of these molecules, thus supporting the idea that renal adaptation following a total proctocolectomy depends, at least in part, upon the molecular induction which is principally regulated by circulating aldosterone.

Total proctocolectomy and ileal J-pouch anal anastomosis for chagasic megacolon with fecaloma: report of a case.

Megacolon, resulting in severe constipation, is one of the most common manifestations of Chagas' disease. We herein report a case of megacolon with fecaloma in a 39-year-old Brazilian man who presented with severe constipation. He underwent a total proctocolectomy and ileal J-pouch anal anastomosis. Histologically, there was a marked thickening of the proper muscle layer, and a moderate decrease in the myoenteric nerve plexuses and neurons in the megacolon area. A feasible outcome has been achieved after a 1-year follow-up. A total proctocolectomy with ileal J-pouch anal anastomosis may therefore be one of the useful strategies for the surgical treatment of patients with chagasic megacolon.

Functional outcome of stapled ileal pouch-anal canal anastomosis versus handsewn pouch-anal anastomosis.

This study was conducted to determine whether stapled ileal pouch-anal canal anastomosis (IACA) preserving the anal transitional zone (ATZ) or hand-sewn ileal pouch-anal anastomosis with mucosectomy (IPAA) is more beneficial in achieving disease eradication and better postoperative function. IACA was performed in 10 patients with ulcerative colitis (UC) and 10 patients with familial adenomatous polyposis (FAP), 15 of whom were examined proctoscopically. IPAA was performed in 4 patients with UC and 8 patients with FAP. The mean maximum resting pressure (MRP) was 55 mmHg in the IACA group and 34 mmHg in the IPAA group (P < 0.01). The anorectal inhibitory reflex was positive in 18 patients (90%) from the IACA group and 5 (42%) from the IPAA group (P < 0.05). The pre- and postoperative MRPs were 61 mmHg and 55 mmHg, respectively, in the IACA group vs 63 mmHg and 34 mmHg, respectively, in the IPAA group (P < 0.01). Whereas 16 (80%) of the 20 IACA patients could discriminate feces from gas, only 4 (33%) of the 12 IPAA patients could (P < 0.05). The mean observation period was 2.3 years, the mean length of the columnar cuff was 2.8 cm, and no case of dysplasia or adenoma was seen. Postoperative function is more favorable following IACA than following IPAA, both physiologically and symptomatically. However, long-term surveillance of the residual mucosa is necessary before making a final recommendation.

Attenuated familial adenomatous polyposis associated with advanced rectal cancer in a 16-year-old boy: report of a case.

We herein present a case of attenuated familial adenomatous polyposis (AFAP) with advanced rectal cancer in a 16-year-old boy. His mother and younger brother both had subcutaneous soft tissue tumors in the back and sparse-type colorectal polyposis. His mother also had dental anomalies and gastric fundic gland polyposis. The patient was admitted to our hospital for investigation of bloody stools. Barium enema and colonofiberscopy revealed advanced rectal cancer and sparse (<50) colorectal polyps. He also had dental anomalies, a subcutaneous soft tissue tumor in the back, and gastric fundic gland polyposis as extracolonic manifestations. A total proctocolectomy and ileoanal anastomosis were performed, and histological examination of the resected specimens confirmed moderately differentiated adenocarcinomas of the rectum with metastases to the regional lymph nodes. The other colorectal polyps were tubular adenomas with no evidence of malignancy. Germline mutations in the APC gene were observed in codons 486, 545, 1493, and 1556. This case serves to demonstrate that a total proctocolectomy with ileoanal anastomosis should be the procedure of choice for young patients found to have advanced rectal cancer associated with FAP.

The failed pelvic pouch: conversion to a continent ileostomy.

BACKGROUND: Excision of the ileal pouch-anal anastomosis (IPAA) with construction of a conventional ileostomy is in general the ultimate procedure after unsuccessful salvage surgery. Conversion of the IPAA to a continent ileostomy (CI) is an alternative. METHODS: The clinical outcome of 13 patients operated with conversion of IPAA into CI was evaluated. Median follow-up was 6 years. One patient was lost to follow-up. RESULTS: There were two failures with pouch excision. At follow-up, ten patients with intact CI were fully continent and none needed to use a stoma appliance. Revisional surgery had been required in 8 patients. CONCLUSIONS: Conversion of a failed IPAA into CI is a feasible procedure that may be considered an alternative to Brooke's ileostomy in motivated patients. The operation should ideally be done in specialized units.

High-magnification chromoscopic pouchoscopy: a novel in vivo technique for surveillance of the anal transition zone and columnar cuff following ileal pouch-anal anastomosis.

BACKGROUND: Persistence of underlying disease in the residual rectal mucosa and anal transition zone (ATZ) following ileal pouch-anal anastomosis (IPAA) for ulcerative colitis and familial adenomatous polyposis provides a site for potential malignancy. For this reason endoscopic surveillance is performed, although conventional assessment may be unreliable. We hypothesized that the novel technique of high-magnification chromoscopic pouchoscopy (HMCP) may permit accurate anatomical localization of this high risk zone in vivo and permit improved biopsy accuracy. PATIENTS AND METHODS: We studied 132 patients with IPAA using HMCP. Three distinct zones were defined using magnification endoscopy: ATZ, appearing as a linear cellular marix; columnar cuff, identifiable by a type I crypt pattern; and ileal pouch body, appearing as villous projections. Quadrantic biopsies of these zones were taken in addition to biopsies of any other lesions noted. RESULTS: A total of 1586 biopsies were taken from zones 1-3 (median, 12; range, 5-16 per patient). Overall biopsy-targeting accuracies using magnification guidance as compared with histopathology were 82%, 73% and 91% for the ATZ, cuff and pouch body, respectively. No dysplasia was identified in the quadrantic surveillance biopsies. Histologically confirmed columnar metaplasia was visualized in vivo using magnification chromoscopy. Patients with IPAA >3 years' duration were more likely to have pouch reservoir columnar metaplasia as compared to those <3 years (p<0.01). Pouch reservoir metaplasia was associated with a pre-morbid diagnosis of high-grade dysplasia or carcinoma within the premorbid colectomy specimen (p<0.001). CONCLUSIONS: This is the first study to evaluate this novel application of high magnification chromoscopy. Magnification pouchoscopy is a valid predictor of ATZ and cuff anatomy, permitting accurate biopsy targeting. Further randomized studies validating this technique with an emphasis on dysplasia detection in larger cohorts are required.

Familial adenomatous polyposis. Surgical treatment: when and how.

Familial adenomatous polyposis is an autosomal dominated inherited disease, caused by the mutation of the tumour suppressor gene adenomatous polyposis coli on chromosome 5. Despite being a rare disorder, accounting for some 1% of colorectal cancers, it represents an interesting model of hereditary disease, because of its intrinsic characteristics, conventionally defined by the presence of more than 100 colorectal polyps, as well as extra-colon manifestations, the attenuated form of the disease, genetic aspects, the inevitable progression to colorectal cancer and hence the correct therapy to treat or prevent the fatal evolution of the disease. Surgical treatment is based above all on two techniques: ileorectal anastomosis, which requires careful surveillance of rectal remnant, and ileal pouch-anal anastomosis, which totally eradicates the disease. The suitability of using these two techniques is discussed in view of new genetic and clinical findings, acquired from personal experience and from the literature.

The ileoanal pouch procedure in the long-term perspective: a critical review.

An ileo-pouch anal anastomosis (IPAA) has become the gold standard procedure for ulcerative colitis and familial adenomatous polyposis. Clinical results on the pelvic pouch procedure have often been encouraging; when confronted with the different surgical options, the majority of patients select IPAA as the best operation. However, even if IPAA is a great innovation, it is by no means the first choice for all patients. For patients old enough to join in a responsible discussion, the pros and cons of the various operations must be carefully described; the choice of surgical procedure must meet the patient's wishes and appear soundly based to the surgeon. The young age of most patients has to be considered and a long follow-up time is required to establish whether and, if so, to what extent the operation may adversely impact the patient's continence, sex life, fertility, and quality of life. The risk of cancer transformation in the residual rectal mucosa in the muscular or columnar cuff is another important factor that may influence the eventual decision. This article critically reviews our experience and the literature.
