Syndrome of inappropriate secretion of antidiuretic hormone after total proctocolectomy for ulcerative colitis

We report a case of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) after total proctocolectomy followed with ileal pouch-anal anastomosis (TPC-IPAA) for ulcerative colitis (UC). The patient was a 46-year-old woman. She was diagnosed with UC of pancolitis in 2000. High grade dysplasia was detected in the transverse colon after a surveillance colonoscopy in 2021. She underwent laparoscopy-assisted TPC-IPAA. On the sixth postoperative day, she had a decreased level of consciousness that worsened on the following day. Her laboratory data showed a serum sodium level of 108 mEq/L and the plasma osmolality was 234 mOsm/kg. We did not find any other abnormalities in the laboratory examination that could cause hyponatremia. Computed tomography scan showed no central nervous system disturbances such as a pituitary tumor, antidiuretic hormone-producing tumors, or pulmonary diseases. The patient was diagnosed with Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) caused by surgical invasion. We started to administer 3% sodium chloride slowly to improve the hyponatremia. Her serum sodium level became normal and stable. Although it is rare for SIADH to be caused by abdominal surgery, if hyponatremia is observed after surgery, the possibility of postoperative SIADH should be considered.

Long-term prognosis of familial adenomatous polyposis with or without mucosectomy

PURPOSE

This study primarily aimed to compare the long-term prognosis of patients who underwent total colectomy/proctocolectomy with or without mucosectomy to the dentate line for the diagnosis of familial adenomatous polyposis (FAP).

METHODS

Patients who underwent total colectomy/proctocolectomy for FAP between January 1979 and December 2020 and were followed up at Hamamatsu University Hospital were included in this study. Those who underwent total proctocolectomy with hand-sewn ileal pouch-anal anastomosis were defined as the mucosectomy group. Those who underwent total colectomy or total proctocolectomy using the stapled ileal pouch-anal anastomosis approach were defined as the no mucosectomy group.

RESULTS

A total of 61 individuals (37 families) were diagnosed during the surveillance period (median, 191 months). Between the mucosectomy (n = 24) and no mucosectomy groups (n = 34), metachronous rectal cancer was significantly more common in the no mucosectomy group (21% in no mucosectomy vs. 0% in mucosectomy, P = 0.02). Overall survival in the no mucosectomy group was worse than that in the mucosectomy group (84.5% in no mucosectomy vs. 100% in mucosectomy at 120 months, 81.1% vs. 90.0% at 240 months, 50.6% vs. 75.0% at 360 months, P = 0.09). Cox regression analysis revealed an independent effect of not performing mucosectomy on overall survival (P = 0.03).

CONCLUSION

Long-term surveillance revealed that colectomy or total proctocolectomy without mucosectomy had a negative impact on the overall survival of patients with FAP. Therefore, we recommend total proctocolectomy with mucosectomy, i.e., hand-sewn ileal pouch-anal anastomosis, for FAP.

Symptomatic familial adenomatous polyposis in an adolescent: A case report

INTRODUCTION

Familial adenomatous polyposis (FAP) is an inherited colorectal cancer syndrome characterized by several adenomatous polyps of the gastrointestinal mucosa with a universal risk of colorectal cancer in a lifetime. FAP is usually asymptomatic in the first decade of life.

CASE PRESENTATION

We report a case of a 13-year-old girl diagnosed with FAP who presented in our center with symptoms of hematochezia along with a positive history of the untimely demise of her father and elder sister with similar symptoms.

DISCUSSION

FAP is an autosomal dominant disease affecting both male and female equally with variable penetrance. Diagnosis is made by finding hundreds to thousands of adenomatous polyps in the colon and rectum, and molecular analysis of the APC gene which forms the definitive diagnosis. Prophylactic laparoscopic total proctocolectomy with ileorectal anastomosis is a safe and feasible surgical option with a low risk of complications among adolescents. An endoscopic/colonoscopic procedure is recommended every 6 to 12 months after surgery to assess the anastomosis site, pouch, and residual rectum.

CONCLUSION

FAP, a rare disease entity in adolescents should be managed by appropriate diagnostic procedures, early prophylactic surgery, and regular lifelong follow-up.

Ulcerative colitis-associated rectal cancer resected and diagnosed by rectovesical fistula: a case report

Ulcerative colitis (UC), which mainly consists of mucosal lesions, rarely form colovesical or rectovesical fistulas, although few cases of fistula formation associated with comorbidities have been reported. We report a case of UC-associated rectal cancer diagnosed following symptoms associated with rectovesical fistula. A 40-year-old man with a 31-year history of extensive UC presented with difficulty in defecation. Two years before the current presentation, he had experienced pneumaturia, and the examination then had revealed a rectal neoplastic lesion and rectovesical fistula; however, tissue biopsy showed no malignancy. Therefore, he requested for observation with no further treatment. Current examination suggested the rectal tumor had grown to invade the bladder. Tissue biopsy showed no malignancy. However, the clinical symptoms and examination findings strongly indicated UC-associated rectal cancer with bladder invasion; thus, open total proctocolectomy with partial cystectomy was performed. Histopathological evaluation of the rectal neoplastic lesion revealed UC-associated rectal cancer originating from the inflammatory mucosa, and the rectovesical fistula was found to be caused by the rectal cancer invading the bladder. Therefore, other colorectal cancers should be considered even though tissue biopsy does not reveal malignant lesions in UC patients with fistula.

The extent of colorectal resection and short-term outcomes in patients with ulcerative colitis

OBJECTIVE

There is limited literature on the impact of the extent of resection on short-term outcomes in patients with ulcerative colitis (UC) in an elective setting. The aim of this study was to better understand the impact of approach and extent of resection on short-term outcomes for patients undergoing total proctocolectomy (TPC) and subtotal colectomy (STC) for UC.

METHODS

Patients with UC who underwent elective TPC or STC were captured from the ACS-NSQIP® 2011-2018 database and divided into four cohorts: Open TPC (O-TPC), Laparoscopic TPC (L-STC), Open STC (O-STC), and Laparoscopic STC (L-STC). Baseline and perioperative variables were compared between the four groups alongside 30-day mortality and 30-day complication rates.

RESULTS

Of 3387 patients, 368 (10.9%) underwent O-STC, 406 (12%) underwent O-TPC, 1958 (58%) underwent L-STC, and 655 (19%) underwent L-TPC. Overall rate of prolonged length of stay (LOS) was 27% and 9% needed a blood transfusion. There was no difference in the risk of complications between open TPC and open STC. Those who had open surgery had a higher risk of complications and prolonged LOS. Patients who had L-TPC had prolonged LOS compared to patients who had L-STC, but less compared to those who had O-STC.

CONCLUSION

Elective surgery for UC is associated with high rates of prolonged LOS and blood transfusion despite MIS approaches. Short-term outcomes and LOS are more impacted by the operative approach than the extent of resection. Despite this laparoscopic TPC has higher rates of prolonged LOS when compared to laparoscopic STC.

Risk factors for postoperative stoma outlet obstruction in ulcerative colitis

BACKGROUND

Current medical treatments can achieve remission of ulcerative colitis (UC). Surgery is required when potent drug treatment is ineffective or when colon cancer or high-grade dysplasia develops. The standard procedure is restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis, commonly performed as two- or three-stage RPC with diverting ileostomy. Postoperative stoma outlet obstruction (SOO) is frequent, but the causes are not well known.

AIM

To identify the risk factors for SOO after stoma surgery in patients with UC.

METHODS

We retrospectively reviewed the files of 148 consecutive UC patients who underwent surgery with stoma construction. SOO was defined as small bowel obstruction symptoms and intestinal dilatation just below the penetrating part of the stoma on computed tomography. Patients were divided into two groups: Those who developed SOO within 30 d after surgery and those who did not. Patient characteristics, intraoperative parameters, the stoma site, and rectus abdominis muscle thickness were collected. Moreover, we identified the patients who repeatedly developed SOO. Univariate and multivariate analyses were performed to identify risk factors for SOO and recurring SOO.

RESULTS

Eighty-nine patients who underwent two-stage RPC were included between January 2008 and March 2020. Postoperatively, SOO occurred in 25 (16.9%) patients after a median time of 9 d (range 2-26). Compared to patients without SOO, patients with SOO had a significantly higher rate of malignant tumors or dysplasia (36.0% vs 17.1%, P = 0.032), lower total glucocorticoid dose one month before surgery (0 mg vs 0 mg, P = 0.026), higher preoperative total protein level (6.8 g/dL vs 6.3 g/dL, P = 0.048), higher rate of loop ileostomy (88.0% vs 55.3%, P = 0.002), and higher maximum stoma drainage volume (2300 mL vs 1690 mL, P = 0.004). Loop ileostomy (OR = 6.361; 95%CI 1.322–30.611; P = 0.021) and maximum stoma drainage volume (OR = 1.000; 95%CI 1.000–1.001; P = 0.015) were confirmed as independent risk factors for SOO. Eighteen patients with SOO were treated conservatively without recurrence (sSOO group). Seven (28.0%) patients repeatedly developed SOO (rSOO group) during the observation period. A significant difference was observed in the rectus abdominis muscle thickness between the two groups (sSOO 9.3 mm, rSOO 12.7 mm, P = 0.006). Muscle thickness was confirmed as an independent risk factor for recurring SOO (OR = 2.676; 95%CI 1.176-4.300; P = 0.008).

CONCLUSION

In this study, high maximum stoma drainage volume and loop ileostomy are independent risk factors for SOO. Additionally, among patients with a thick rectus abdominis muscle, the risk of SOO recurrence is high.

The role of fecal calprotectin in the diagnosis of acute pouchitis following IPAA for ulcerative colitis: a systematic clinical review

PURPOSE

Total proctocolectomy (TPC) with ileal pouch anal anastomosis (IPAA) is commonly performed for patients with refractory ulcerative colitis (UC). Pouchitis occurs in 20-50% of these patients. Fecal calprotectin is a biomarker that correlates well with the pouchitis disease activity index. However, its role in the diagnosis and management of acute pouchitis has not been thoroughly defined. The aim of this study is to review previously established cut-off values and contextualize the clinical utility of fecal calprotectin.

METHODS

Search of Medline, EMBASE, CENTRAL, and PubMed was performed. Articles were eligible if they measured fecal calprotectin in the setting of pouchitis in patients who underwent TPC with IPAA for UC. Risk of bias of the included studies was evaluated with the QUADAS-2.

RESULTS

From 117 relevant citations, seven studies with 256 patients (44.8% female, 39.88 years) met inclusion criteria. The pooled prevalence of pouchitis was 42%. The derived fecal calprotectin cut-off values ranged from 56 to 494 μg/g. The corresponding sensitivities and specificities ranged from 57 to 100% and 38 to 92%, respectively. The area under the curve was reported in three studies and ranged from 0.832 to 0.840.

CONCLUSION

Fecal calprotectin may be a reliable diagnostic tool for acute pouchitis in patients following TPC with IPAA for UC. The high sensitivity of fecal calprotectin for detection of pouchitis makes it a valuable test for ruling out pouchitis. When used in conjunction with other biomarkers, the high specificity offers value in ruling in pouchitis. However, given the complexity of this disease process, relying solely on biomarkers for diagnosis is currently unreasonable.

Total proctocolectomy with end ileostomy for acute onset of ulcerative colitis during chemoradiotherapy for lung adenocarcinoma (successfully treated by surgery): a case report

Background

Ulcerative colitis (UC) developing during chemotherapy is very rare. Here, we describe a case of acute onset during chemoradiotherapy for lung adenocarcinoma, requiring a total proctocolectomy.

Case presentation

A 52-year-old man was admitted to the hospital for chemoradiotherapy of lung cancer. He had no obvious history of gastrointestinal diseases, and concurrent chemoradiotherapy was initiated. Thirteen days after 2 cycles of cisplatin and vinorelbine, he experienced persistent hematochezia. Findings of the colonoscopy revealed edematous thickening from the rectum to the transverse colon, suggesting UC, drug-induced colitis, or infectious colitis. Results from bacterial culture were negative for Clostridium difficile and methicillin-resistant Staphylococcus aureus (MRSA). Immunohistological staining for cytomegalovirus was also negative. Although he was clinically diagnosed with UC and treated with intravenous glucocorticoid, his symptoms gradually worsened and an abdominal X-ray revealed megacolon. Thirty-five days after conservative therapy, a total proctocolectomy with end permanent ileostomy was performed. Based on pathological findings and clinical course, he was diagnosed with UC.

Conclusion

Although the pathogenesis of UC during chemotherapy has been unknown, chemotherapy could be one of the causes of UC in this case. UC should be included in the differential diagnosis in patients with progressive colitis during chemotherapy.

Acute histologic inflammatory activity and postoperative outcomes in pediatric patients with ulcerative colitis

BACKGROUND

The aim of this study was to determine whether acute histologic inflammatory activity at the rectal margin predicts postoperative complications in children with ulcerative colitis following ileal pouch-anal anastomoses (IPAA).

METHODS

Patients who underwent IPAA following previous total abdominal colectomy for ulcerative colitis between 2006 and 2014 were included. Data collected included demographics, operative and postoperative data, histologic grading of the rectal margin at time of IPAA, and stooling outcomes at one, six and 12 months following ileostomy closure.

RESULTS

Twenty-seven patients were included. Acute inflammation scores ranged between 2 and 13. Unadjusted and adjusted models showed no statistically significant relationship between inflammation and presence of any postoperative complications, number of daily stools, nighttime stooling, soiling, or stool-altering medication usage.

CONCLUSION

Acute histologic inflammatory activity at the rectal margin is not associated with increased rates of postoperative complications following IPAA creation in children, nor with poorer continence outcomes following ileostomy closure.

Clinical Outcomes After Ileal Pouch-Anal Anastomosis in Pediatric Patients

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is the standard surgical reconstruction for patients with familial adenomatous polyposis (FAP) and ulcerative colitis (UC) who undergo total proctocolectomy (TPC). Although patients receive the same reconstruction, their postoperative complications can differ. We hypothesize that indication for TPC and other preoperative clinical factors are associated with differences in postoperative outcomes following IPAA.

METHODS

A retrospective cohort of pediatric patients who underwent proctocolectomy with IPAA from 1996 to 2016 was identified. Preoperative, operative, and postoperative clinical variables were collected. Univariate analyses were performed to evaluate for relevant postoperative clinical differences.

RESULTS

Seventy-nine patients, 17 with FAP and 62 with UC, were identified. FAP patients spent a mean of 1125 ± 1011 d between initial diagnosis and first surgery compared to 585 ± 706 d by UC patients (P = 0.038). FAP patients took a mean of 57 ± 38 d to complete TPC with IPAA compared to UC patients at 177 ± 121 d (P < 0.001). FAP and UC patients did not differ in mean number of bowel movements at their 6-mo postoperative visit (4.7 ± 2.1 versus 5.6 ± 1.9, respectively [P = 0.134]). FAP patients were less likely to experience pouchitis (P = 0.009), pouch failure (P < 0.001), and psychiatric symptoms (P = 0.019) but more likely to experience bowel obstruction (P = 0.002).

CONCLUSIONS

IPAA is a safe, restorative treatment for FAP and UC patients after TPC. Based on diagnosis and preoperative course, there are differences in morbidity in IPAA patients. Clinical data such as these will allow surgeons to help families anticipate their child's preoperative and postoperative courses and to maximize successful postoperative outcomes.

Total abdominal colectomy vs. restorative total proctocolectomy as the initial approach to medically refractory ulcerative colitis

PURPOSE

There is scant data assessing the consequences of staging restorative proctocolectomy for ulcerative colitis. The aim of the study is to compare outcomes of initial vs. staged restorative proctocolectomy.

METHODS

Patients completing restorative proctocolectomy, including ileostomy reversal, during 2006-2012 were identified from an IRB-approved database. Demographics, treatment variables, and perioperative outcomes were assessed.

RESULTS

Out of 521 patients, 322 (62%) underwent initial total abdominal colectomy before restorative proctectomy. This group was associated with more common preoperative anemia, leukocytosis, hypoalbuminemia, severe colitis, steroids and biologics use, decreased proximal ileostomy rate at the time of completion restorative proctectomy (92.5 vs 97.5%, p = 0.023), shorter hospital stay (6.6 vs 7.8, p < 0.001), and marginally decreased pelvic sepsis rate (6.2 vs 11.1%, p = 0.05) compared with patients having initial restorative proctocolectomy. However, they also required longer combined postoperative hospital stays (17 vs 12 days, p < 0.001) and treatment span (10.4 vs 5.7 months, p < 0.001) to complete all surgical stages and they were associated with increased overall postoperative surgical site infection, hemorrhage, and small bowel obstruction rates. Pouch function and QOL were comparable between the groups, except for increased nightly bowel movements in the initial abdominal colectomy group (2.5 ± 2.2 vs 2.1 ± 1.8, p = 0.012).

CONCLUSIONS

Patients undergoing initial total abdominal colectomy require longer treatment time and experience increased overall morbidity, but ultimately experience comparable ileal pouch outcomes when compared to patients undergoing initial restorative proctocolectomy.

Restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: A narrative review

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) is the gold standard surgical treatment for ulcerative colitis. However, despite the widespread use of RP-IPAA, many aspects of this treatment still remain controversial, such as the approach (open or laparoscopic), number of stages in the surgery, type of pouch, and construction type (hand-sewn or stapled ileal pouch-anal anastomosis). The present narrative review aims to discuss current evidence on the short-, mid-, and long-term results of each of these technical alternatives as well as their benefits and disadvantages. A review of the MEDLINE, EMBASE, and Ovid databases was performed to identify studies published through March 2016. Few large, randomized, controlled studies have been conducted, which limits the conclusions that can be drawn regarding controversial issues. The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases. Regarding 2- and 3-stage RP-IPAA, patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables, making any comparisons extremely difficult. The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly, although the J pouch is generally preferred by surgeons. Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages, and there is no clear benefit of one technique over the other.

Feasibility of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis and total colectomy with ileorectal anastomosis for familial adenomatous polyposis: results of a nationwide multicenter study

BACKGROUND

Data supporting the safety and feasibility of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA) and total colectomy with ileorectal anastomosis (TC-IRA) for patients with familial adenomatous polyposis (FAP) are limited. The aim of this study was to clarify the feasibility and morbidity of laparoscopic TPC-IPAA and TC-IRA for patients with FAP, using a large Japanese multicenter dataset.

METHODS

Data on 256 patients with FAP who underwent TPC-IPAA (n = 171) or TC-IRA (n = 85) at 23 institutions between the years 2000 and 2012 were collected. Short- and long-term clinical outcomes were compared between laparoscopic and open approaches for each procedure.

RESULTS

Among the 256 patients with FAP, a total of 126 patients underwent laparoscopic surgery, consisting of 74 laparoscopic TPC-IPAAs and 52 laparoscopic TC-IRAs. The proportion of the FAP patients who underwent laparoscopic surgery increased during the study period, reaching 79 % of all TPC-IPAAs and 82 % of all TC-IRAs in the final two years covered by the data. In both TPC-IPAA and TC-IRA, the laparoscopic approach was associated with a longer operative duration but a similarly low postoperative morbidity and comparably adequate anal function compared with the open approach. The overall survival and the incidence of desmoid tumor were also comparable between the laparoscopic and open approaches in both procedures.

CONCLUSIONS

Laparoscopic TPC-IPAA and TC-IRA are both feasible options-with low rates of morbidity, good functional outcomes, and excellent overall survival rates-in patients with FAP. Since the data indicate that laparoscopic TPC-IPAA and TC-IRA are feasible, they also support the recent increase in laparoscopic surgery for patients with FAP in Japan.

Prevalence of laparoscopic surgical treatment and its clinical outcomes in patients with familial adenomatous polyposis in Japan

BACKGROUND

Laparoscopic surgery is becoming the preferred technique for most colorectal interventions. This study aimed to clarify the time trend of surgical treatment for familial adenomatous polyposis (FAP) and its relevance to clinical outcomes in Japan over a 13-year period.

METHODS

This was a multicenter retrospective cohort study comprising 23 specialist institutions for colorectal disease and a cohort of 282 FAP patients who underwent total colectomy or proctocolectomy during 2000-2012. Patient clinical backgrounds and surgical outcomes were compared between the first and second halves of the study period.

RESULTS

The proportion of surgical types adopted over the entire study period was 46, 21, 30, and 3 % for ileoanal anastomosis (IAA), ileoanal canal anastomosis, ileorectal anastomosis, and permanent ileostomy, respectively. FAP patients undergoing laparoscopic surgery have increased since 2008 and reached 74 % in the past 3 years. In particular, the number of patients undergoing laparoscopic proctocolectomy with IAA increased approximately four-fold from the first to the second half of the study period. A laparoscopic approach was increasingly used in patients with coexisting colorectal malignancies. Despite this trend, surgical results of the laparoscopic approach between the two study periods showed similar morbidity, pouch operation and stoma closure completion rates. No postoperative mortality was observed in this series, and laparoscopic surgery was comparable to open surgery in terms of stoma closure rate, incidence of intra-abdominal/abdominal desmoid tumors, and postoperative survival rate in both study periods.

CONCLUSION

Laparoscopic approach is increasingly being adopted for prophylactic FAP surgery in Japan and may provide clinically acceptable practical outcomes.

Electrothermal bipolar vessel ligation improves operative time during laparoscopic total proctocolectomy: a large single-center experience

BACKGROUND

Laparoscopic total proctocolectomy (TPC) with or without ileoanal pouch is a major operation for which the traditional benefits of laparoscopy were not immediately apparent, in part due to the longer operating times. The use of energy devices has been shown to improve operative outcomes for patients who undergo laparoscopic segmental colectomies, but there are limited data for laparoscopic TPC (LTPC).

METHODS

All patients who underwent LTPC between January 2002 and July 2011 were identified from a prospectively maintained institutional-review-board-approved database. Univariate and multiple linear regression analyses were performed to assess the impact of electrothermal bipolar vessel sealers (EBVS) for vessel ligation on operative time. Secondary outcomes included vessel ligation failures, estimated blood loss, and other intra- and postoperative outcomes.

RESULTS

One hundred and forty-five patients underwent LTPC, including 126 restorative ileoanal pouch and diverting ileostomy operations and 19 TPC and end ileostomy procedures. Fifteen percent of LTPCs were totally laparoscopic, 45 % were laparoscopic-assisted, 32 % were hand-assisted, and 8 % were laparoscopic-converted cases. Laparoscopic vessel ligation was performed using EBVS (76 %), endoscopic staplers (12 %), or hybrid techniques (12 %). Vessel ligation groups were similar in demographics, body mass index, surgical indication, immunosuppression, and prior surgery. EBVS were associated with shorter median operative times (247 vs. 290 vs. 300 min, p = 0.018) and fewer vessel ligation failures (1 vs. 11 vs. 12 %, p = 0.027) compared with endoscopic staplers and hybrid techniques, respectively. There were no differences in estimated blood loss and intra-operative complications among the three groups. Length of stay, 30-day morbidity, and 30-day re-operation rates were also similar. On multiple linear regression analysis, EBVS were a significant predictor of operative time (p = 0.019).

CONCLUSIONS

Routine use of electrothermal bipolar vessel ligation for LTPC is associated with shorter operative time and fewer vessel ligation failures without higher risk of complications than other vessel control methods.

FAP related periampullary adenocarcinoma

INTRODUCTION

The risk of periampullary neoplasia in patients with familial adenomatous polyposis (FAP) is significantly increased compared to the general population.

PRESENTATION OF CASE

We herein report the case of a 47-year-old woman with classic familial adenomatous polyposis with a history of total proctocolectomy for FAP who presented with an ulcerous ampullary lesion 8 years after primary colorectal surgery. Interestingly, the patient had not enrolled to optimal postoperative upper endoscopy follow-up. The patient underwent a Whipple procedure. Histology demonstrated a T2N0 ampullary adenocarcinoma.

DISCUSSION

Periampullary disease in patients with familial adenomatous polyposis occurs increasingly, especially in the subset of patients without proper endoscopic follow-up. Current recommendations concerning upper endoscopy and appropriate management are herein discussed; the importance of optimal postoperative endoscopy after total proctocolectomy in the FAP setting is discussed.

CONCLUSION

Periampullary cancer carries a significant risk in patients with FAP and proper endoscopic follow-up should be applied in this special patient group in order to manage ampullary manifestations of the disease in a timely manner.
