Intra-abdominal desmoid tumors in familial adenomatous polyposis: How much do clinical and surgical variables interfere with their development?

OBJECTIVE

Familial Adenomatous Polyposis is a complex hereditary disease that exposes the carrier to a great risk of Colorectal Cancer (CRC). After prophylactic surgery, intra-abdominal desmoid tumors are known to be one the most important cause of death. Therefore, recognition of increased-risk patients and modification of operative strategy may be crucial.

AIM

The objective of this study was to estimate the desmoid tumor risk in relation to various surgical and clinical variables.

METHODS

Patients who had undergone polyposis since 1958 were included in the study. After exclusion criteria were met, those who had developed desmoid tumors were selected to undergo further evaluation.

RESULTS

The study revealed that the risk of developing desmoid tumors was associated with various factors such as sex ratio, colectomy, and reoperations. On the other hand, the type of surgery, family history, and surgical approach did not affect the risk of developing desmoid tumors. The data collected from 146 polyposis patients revealed that 16% had desmoid polyps. The sex ratio was 7:1, and the median age at colectomy was 28.6 years. Family history, multiple abdominal operations, and reoperations were some of the characteristics that were common in desmoid patients.

CONCLUSION

Recognition of clinical (female sex) and surgical (timing of surgery and previous reoperations) data as unfavorable variables associated with greater risk may be useful during the decision-making process.

Current trends regarding protective ileostomy after restorative proctocolectomy

The decision to perform a protective ileostomy after ileoanal-pouch anastomosis is con- troversial, and most of the discussion is based on its advantages and disadvantages. Al- though a temporary intestinal diversion has been routinely indicated in most patients, this choice is also associated with complications. The present work aims to review the outcomes after restorative proctocolectomy with or without a protective ileostomy in the treatment of ulcerative colitis and polyposis syndromes. Most papers emphasize that di- version protects against anastomosis leaks; consequently, it may prevent pelvic sepsis and pouch failure. Otherwise, a defunctioning ileostomy may cause morbidity such as dehydra- tion, electrolyte imbalance, psychological problems, skin irritation, anastomosis strictures and intestinal obstruction, among others. There are those who believe that the omission of an ileostomy after the confection of ileal pouches should be reserved for selected patients, with quite acceptable results. The selection criteria should include surgeon, patient and procedure features to ensure a good outcome.

Risk factors for prolonged length of stay after colorectal surgery

Objective Colorectal surgeons often struggle to explain to administrators/payers reasons for prolonged length of stay (LOS). This study aim was to identify factors associated with increased LOS after colorectal surgery.

Design The study population included patients from the 2007 American-College-of-Sur- geons-National-Surgical-Quality-Improvement-Program (ACS-NSQIP) database undergoing ileocolic resection, segmental colectomy, or anterior resection. The study population was divided into normal (below 75th percentile) and prolonged LOS (above the 75th percentile). A multivariate analysis was performed using prolonged LOS as dependent variable and ACS- NSQIP variables as predictive variables. P-value < 0.01 was considered significant.

Results 12,269 patients with a median LOS of 6 (inter-quartile range 4-9) days were includ- ed. There were 2,617 (21.3%) patients with prolonged LOS (median 15 days, inter-quartile range 13-22). 1,308 (50%) were female, and the median age was 69 (inter-quartile range 57-79) years. Risk factors for prolonged LOS were male gender, congestive heart failure, weight loss, Crohn's disease, preoperative albumin < 3.5 g/dL and hematocrit < 47%, base- line sepsis, ASA class ≥ 3, open surgery, surgical time ≥ 190 min, postoperative pneumonia, failure to wean from mechanical ventilation, deep venous thrombosis, urinary-tract in- fection, systemic sepsis, surgical site infection and reoperation within 30-days from the primary surgery.

Conclusion Multiple factors are associated with increased LOS after colorectal surgery. Our results are useful for surgeons to explain prolonged LOS to administrators/payers who are critical of this metric.

Laparoscopy adjuvant total colorectal resection for the treatment of familial adenomatous polyposis (FAP)

OBJECTIVE

To discuss and evaluate the safety and value of laparoscopy adjuvant total colorectal resection for the treatment of familial adenomatous polyposis (FAP).

METHODS

From March 2010 to June 2015, 38 cases were retrospectively analyzed and divided into 2 groups, of which 17 cases used laparoscopy adjuvant total colorectal resection, and 21 cases used conventional laparotomy. Clinical data were obtained, and the safety and prognosis were observed.

RESULTS

Seventeen cases using laparoscopy adjuvant total colorectal resection achieved success with no conversion to laparotomy and intraoperative complications. There was no significant difference in operation time between the two groups. There were significant differences in blood loss, the length of incision, postoperative recovery time of intestinal function and postoperative hospital stay between the two groups (P < 0.05). The trauma in laparoscopy group was less, and could recover faster, and there was no significant difference in complications between the two groups. In addition, there were no recurrence, distant metastasis and death in the follow-up period from 6 to 56 months.

CONCLUSION

Laparoscopy adjuvant total colorectal resection is more safe and feasible, which has minimal invasion and can recover fast.

Laparoscopic Versus Open Restorative Proctocolectomy for Familial Adenomatous Polyposis

PURPOSE

This study compared outcomes after laparoscopic (LAP) or conventional (open) total proctocolectomy with outcomes after ileal J-pouch anal anastomosis (IPAA) at a single institution.

METHODS

Charts from 133 familial adenomatous polyposis patients (1997-2013) were reviewed. Demographic data (age, sex, color, American Society of Anesthesiologists [ASA] status, previous surgery, and body mass index) and surgical outcomes (length of stay, early and late morbidity, reoperation, and mortality rates) were compared among 63 patients undergoing IPAA.

RESULTS

Demographic features were similar among patients (25 open and 38 LAP). Conversely, colorectal cancer at diagnosis prevailed in the open group (60% versus 31.6%; P = .02). Tumor stages (P = .65) and previous surgery index (20% versus 10.5%; P = .46) were similar. Surgical length was longer for LAP (374 versus 281 minutes, P = .003). Short-term complication rates (28% versus 28.9%), hospital stay (10.9 versus 8.9 days), and total long-term reoperations (28% versus 21%) were not statistically different. However, major late morbidity (16% versus 2.6%; P < .001) and late reoperation rates (16% versus 5.2%; P < .05) were greater among open patients. Both groups did not differ regarding pouch failure rates (8% versus 5.2%). There was no operative mortality in the present series.

CONCLUSIONS

(1) LAP IPAA is a safe procedure associated with a low conversion rate, (2) short-term results showed no clear advantages for both approaches, and (3) a greater risk of major late complications and late reoperations should be expected after open procedures.

Short-term outcomes of laparoscopic versus open total colectomy with ileorectal anastomosis: a case-matched analysis from a nationwide database

BACKGROUND

In the current study, we aimed to compare peri- and postoperative 30-day outcomes of patients undergoing laparoscopic versus open total colectomy with ileorectal anastomosis in a case-matched design using data procedure-targeted database.

METHODS

Patients who underwent elective total colectomy with ileorectal anastomosis in 2012 and 2013 were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Patients were divided into two groups according to the type of surgical approach (laparoscopic and open). Laparoscopic and open groups were matched (1:1) based on age, gender, diagnosis, body mass index, and American Society of Anesthesiologists classification. Comorbidities, perioperative, and short-term (30-day) postoperative outcomes were compared between the matched groups.

RESULTS

We identified 1442 patients-549 in the laparoscopic group and 893 patients in the open group. After case matching, there were 326 patients in each group. There were 48 (14.7%) patients who had conversion in the laparoscopic group. The open group had a higher proportion of patients with ascites [0 (0%) vs. 7 (2.1%) p = 0.015], preoperative weight loss [26 (8.0%) vs. 45 (13.8%) p = 0.018], and contaminated wound classifications [Clean/Contaminated 261 (80%) vs. 240 (74%), Contaminated 55 (16.9%) vs. 54 (16.6%), and Dirty/Infected 8 (2.5%) vs. 28 (8.6%), (p = 0.003)]. The laparoscopic group had a significantly longer operative time (242 ± 98 vs. 202 ± 116 min, p < 0.001), shorter hospital stay (9.4 ± 8.5 vs. 13.3 ± 10.7 days, p < 0.001), and lower ileus rate (23.9 vs. 31.0%, p = 0.045) than the open group. After adjusting for covariates, the differences in terms of operative time and hospital stay remained significant [odds ratio (OR): 0.79, confidence interval (CI) 0.74-0.85 and OR 1.36, CI 1.21-1.52, p < 0.001, respectively].

CONCLUSIONS

Laparoscopic approach for total colectomy with ileorectal anastomosis is associated with a shorter hospital stay but longer operative time compared with an open approach.

Current status of prophylactic surgical treatment for familial adenomatous polyposis in Japan

PURPOSE

We conducted this study to clarify the current clinical practice of prophylactic colectomy for patients with familial adenomatous polyposis (FAP) in Japan.

METHODS

This retrospective multi-center cohort study involved 23 specialized institutions for colorectal disease in Japan. We analyzed the records of 147 patients who underwent prophylactic surgical treatment between 2000 and 2012. Patients were divided into Group 1 (2000-2006) and Group 2 (2007-2012) based on their date of surgery.

RESULTS

Age at the time of prophylactic surgery was 27 and 31 years in Groups 1 and 2, respectively. The proportion of attenuated FAP was significantly lower in Group 2 than in Group 1 (1.0 vs. 13 %, respectively). Pathological examination revealed an increased incidence of malignant polyps in the resected specimens from Group 2 patients (10 vs. 23 %, respectively; P = 0.034). Laparoscopic surgery was more frequent in Group 2 than in Group 1 (61 vs. 40 %, respectively). There was no surgical mortality in either group.

CONCLUSION

Prophylactic surgery for FAP results in good short-term surgical outcomes in Japan. The current surgical approach is characterized by limited surgical indications for patients with attenuated FAP, delayed timing of colectomy, and the increasing standardization of laparoscopic surgery.

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.

Desmoid tumors: clinical features and outcome of an unpredictable and challenging manifestation of familial adenomatous polyposis

Background/Aims Desmoid tumors (DTs) are rare, locally invasive neoplasms that may affect 10-25% of familial adenomatous polyposis (FAP) patients. Our aim was to evaluate incidence and clinical presentation among our patients, the potential impact on FAP outcome and to discuss treatment. Materials and methods Charts from 133 FAP (1977-2013) were reviewed. Patients with DTs were separated to retrieve demographic, clinical and management data. Follow-up was focused on disease evolution causing complications or death. Results 19 (14.3%) DTs were diagnosed, either after previous trauma (16) or during FAP surgery (3). This group comprised 8 men (42.1%) and 11 women (57.9%) with an average age of 32.9 years. Intervals from surgical trauma to DTs ranged from 7 to 60 months. ECMs were detected in 12 (63.1%) patients. DTs were located in the abdominal wall (8), abdominal cavity (8), abdominal wall and cavity (2) and left arm (1). Five patients (26.3%) referred family history of DTs. Patients presented severe complications such as small bowel obstruction (4) and hydronephrosis (2), being directly responsible for death in three patients. Conclusions (1) DTs developed in 14.3% of FAP, mostly after surgical trauma; (2) 30% caused severe morbidity; (3) identification of clinical risk factors may help surgeons to develop screening and therapeutic decisions.

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.

Surgical treatment of familial adenomatous polyposis: Dilemmas and current recommendations

Familial adenomatous polyposis (FAP) is an autosomal dominant inherited syndrome characterized by multiple adenomatous polyps (predisposing to colorectal cancer development) and numerous extracolonic manifestations. The underlying genetic burden generates variable clinical features that may influence operative management. As a precancerous hereditary condition, the rationale of performing a prophylactic surgery is a mainstay of FAP management. The purpose of the present paper is to bring up many controversial aspects regarding surgical treatment for FAP, and to discuss the results and perspectives of the operative choices and approaches. Preferably, the decision-making process should not be limited to the conventional confrontation of pros and cons of ileorectal anastomosis or restorative proctocolectomy. A wide discussion with the patient may evaluate issues such as age, genotype, family history, sphincter function, the presence or risk of desmoid disease, potential complications of each procedure and chances of postoperative surveillance. Therefore, the definition of the best moment and the choice of appropriate procedure constitute an individual decision that must take into consideration patient’s preferences and full information about the complex nature of the disease. All these facts reinforce the idea that FAP patients should be managed by experienced surgeons working in specialized centers to achieve the best immediate and long-term results.

Risk of desmoid tumours after open and laparoscopic colectomy in patients with familial adenomatous polyposis

BACKGROUND

Desmoid tumour (DT) is a main cause of death after prophylactic colectomy in patients with familial adenomatous polyposis (FAP). The purpose of this study was to evaluate the impact of prophylactic laparoscopic colectomy on the risk of developing DT in patients with FAP.

METHODS

The database of a single institution was reviewed. Patients with classical FAP with defined genotype who underwent either open or laparoscopic colectomy between 1947 and 2011 were included in the study. The impact of various demographic and clinical features on the risk of developing DT was assessed.

RESULTS

A total of 672 patients underwent prophylactic colectomy: 602 by an open and 70 by a laparoscopic approach. With a median (range) follow-up of 132 (0-516) months in the open group and 60 (12-108) months in the laparoscopic group, 98 patients (16·3 per cent) developed DT after an open procedure compared with three (4 per cent) following laparoscopic surgery. The estimated cumulative risk of developing DT at 5 years after surgery was 13·0 per cent in the open group and 4 per cent in the laparoscopic group (P = 0·042). In multivariable analysis, female sex (hazard ratio (HR) 2·18, 95 per cent confidence interval 1·40 to 3·39), adenomatous polyposis coli mutation distal to codon 1400 (HR 3·85, 1·90 to 7·80), proctocolectomy (HR 1·67, 1·06 to 2·61), open colectomy (HR 6·84, 1·96 to 23·98) and year of surgery (HR 1·04, 1·01 to 1·07) were independent risk factors for the diagnosis of DT after prophylactic surgery.

CONCLUSION

Laparoscopic surgery decreased the risk of DT after prophylactic colectomy in patients with FAP.

Colectomy with ileorectal anastomosis has a worse 30-day outcome when performed for colonic inertia than for a neoplastic indication

AIM

Whether bowel related dysfunction adversely affects postoperative recovery after total colectomy with ileorectal anastomosis (C + IRA) for colonic inertia (CI) has not been previously well evaluated. This study compared the early postoperative outcome of C + IRA for CI and for other noninflammatory indications.

METHOD

Patients undergoing elective C + IRA from 1999 to 2010 were identified from a prospectively maintained database. Since inflammation in the rectum or small bowel may influence the outcome, patients with inflammatory bowel disease were excluded. Patients undergoing surgery for CI (group A) were compared with patients having the operation for other benign noninflammatory diseases (group B). Demographics, American Society of Anesthesiologists (ASA) score, body mass index (BMI), surgical procedure and 30-day complications were assessed.

RESULTS

The study population consisted of 333 patients undergoing elective C + IRA (99 men, mean age 39 ± 16 years). The procedure was laparoscopic in 163 (49%) patients. Groups A (n = 131) and B (n = 202) had similar age and ASA score (39 ± 11 vs 39 ± 19 years, P = 0.4; 2.2 ± 0.5 vs 2.4 ± 0.7). Group A patients had lower BMI (25 ± 5 vs 28 ± 8 kg/m(2) , P = 0.002), more women (99 vs 51%, P < 0.001) and fewer laparoscopic procedures (43 vs 53%, P = 0.04). Compared with group B, group A had a greater incidence of postoperative ileus (32 vs 19%, P = 0.009), higher overall morbidity (36 vs 15%, P < 0.001) and increased length of stay (8.4 ± 6 vs 7.2 ± 5 days, P < 0.006). These differences persisted when subgroups of patients who underwent laparoscopic or open surgery were compared.

CONCLUSION

Although CI is considered a 'benign' condition, patients undergoing C + IRA for this indication have significant morbidity compared with patients having the operation for other noninflammatory benign conditions.
