Does transanal local resection increase morbidity for subsequent total mesorectal excision for early rectal cancer?

AIM: Local excision is recommended for early rectal cancer (pT1). Complementary total mesorectal excision (cTME) is warranted when bad pathological features are present. The impact of a prior local resection on the outcome remains unclear. The aim of this study was to assess if prior local excision increases the morbidity of a subsequent cTME compared with primary TME. METHODS: From 2001 to 2016 all patients who underwent TME after local excision for rectal adenocarcinoma were studied. All were matched (1:1) with patients who underwent primary TME, without neoadjuvant radiochemotherapy. The matching factors included age, sex, body mass index, American Society of Anesthesiologists score and type of surgery. Short-term morbidity and pathological examination of the resected specimen were compared. RESULTS: Forty-one patients were included (14 women, 34%, mean age 65 ± 11 years), comprising classic transanal excision (66%) and transanal endoscopic microsurgery (34%), and were matched to 41 patients who had primary TME. cTME was significantly longer (315 min ± 87 vs 275 min ± 58, P = 0.03). The overall morbidity was 48.8% in the local excision group vs 31.7% in the control group (P = 0.18). Surgical morbidity was 31.7% vs 26.8% (P = 0.8). Anastomotic related morbidity was similar (local excision 17% vs TME 14.6%, P = 0.84) and the mean length of stay was similar (14 days) in both groups. There was a tendency to a worse quality of mesorectal excision in the cTME group (17% vs 5%, P = 0.15). CONCLUSION: Local excision prior to TME for early rectal cancer tends to increase overall morbidity and may worsen the quality of the mesorectal plane but should be considered as a surgical approach in select cases.

Prognostic value and characteristics of N1c colorectal cancer.

AIM: The presence of tumour deposits (TDs) in colorectal cancer (CRC) is associated with poor prognosis. The seventh edition of TNM subclassified a new nodal stage, N1c, characterized by the presence of TDs without any concurrent positive lymph node (LN). It is not clear if the N1c category is or is not equal to LN metastasis. We aimed to examine the prevalence, characteristics and prognostic significance of this new subcategory. METHOD: Consecutive patients who underwent surgery for CRC in two centres (2011-2014) were analysed. N1 cM0 patients were matched against non-N1 cM0 (N0, N1a and N1b) patients for 3-year overall survival (OS) and disease-free survival (DFS). RESULTS: We identified 1122 patients with 648 (57.8%) colonic cancers. In 57 patients (5.1%), N1c status was associated with rectal cancers [rectum = 33/57 (57.9%) vs colon = 24/57 (42.1%); P = 0.029], a higher pathological tumour stage [pT3-T4 N1c = 55/843 (6.5% vspT3-T4 non-N1c = 2/279 (0.7%); P < 0.0001] and vascular emboli [n = 35 (61.4%) vs n = 552 (51.8%); P = 0.0305]. Synchronous metastasis was observed in 23 cases (40%). After a mean follow-up of 31 months, 3-year OS for M0 patients, was 89.4%, 89.1%, 86.6% and 81.8% for N0, N1a, N1b and N1c tumours, respectively. DFS was significantly worse for N1c than for N0 (P = 0.0169), with N1c status having a significant effect on DFS in colonic cancers (P = 0.014). The presence of more than one TD was associated with a significantly worse DFS (P = 0.021). CONCLUSION: Our results indicate that N1c CRC patients should be included among high-risk patients for whom it is widely accepted that adjuvant chemotherapy should be considered.

Is the assessment of submucosal invasion still useful in the management of early rectal cancer? A study of 91 consecutive patients.

AIM: The only studies on the prognosis of T1 tumours are old and investigate colic and rectal cancers. Very few studies use Kikuchi's classification (of dividing submucosa into three strata) to evaluate the depth of the submucosal invasion. This study aimed to assess the pathological risk factors for lymph node metastasis (LNM), and the pathological and oncological results of patients with early rectal cancer (ERC, pT1 tumour). METHOD: Between 2000 and 2014, 91 consecutive patients undergoing surgery [primary total mesorectal excision (TME) or local excision (LE) alone, or LE followed by TME] for ERC were included. RESULTS: Eighteen patients underwent LE, 22 underwent LE followed by TME and 51 underwent primary total TME. After TME (n = 73), 16 (23%) patients had LNM. The LNM rate was 15% for Sm1 tumours, 14% for Sm2 tumours and 30% for Sm3 tumours. In multivariate analysis, lymphovascular invasion (P = 0.027) and high tumour budding (P = 0.037) were the only independent factors predictive of LNM. The depth of submucosal invasion was not associated with an increased risk of LNM. After a mean follow up of 56 ± 46 months, 5-year overall survival, specific survival and disease-free survival were, respectively, 82%, 93% and 75%. No significant difference of survival was found according to the depth of submucosal invasion or to the surgical management. CONCLUSION: Histological features seem to be stronger risk factors for LNM than depth of submucosal invasion. Considering the LNM rate, TME should be discussed after LE in terms of one of these pathological criteria.

Factors influencing mortality and morbidity following colorectal resection in France. Analysis of a national database (2009-2011).

AIM: Correlation between outcome and hospital volume regarding colorectal resection (CRR) has been described, but it suggests that provider variability may have an impact. Our aim was to analyse the influence of institutional characteristics and the impact of volume [high volume (HV) or low volume (LV)] on mortality and morbidity after CRR at a national level. METHOD: Data from 2009-2012, including patient demographics, diagnosis, procedure, mode of admission and discharge and hospital type, were obtained. Each hospital admission was classified as one of four levels of severity. RESULTS: Of 176,444 patients included, 5408 (3.06%) died and 41,240 (23.37%) had a complication. Multivariate analysis showed that factors influencing morbidity were age over 80 years, severity level, pathology other than diverticular disease, male gender, demanding surgery, open surgery and surgery in an HV institution. Factors influencing mortality were the same except for the impact of volume. In HV centres, surgery was significantly more demanding (54.66% vs 47.17%, P < 0.0001), morbidity more frequent (26.59% vs 22.07%, P < 0.0001), but mortality was lower (2.17% vs 3.43%, P < 0.0001). In total, 6038 (3.4%) patients were transferred after surgery. Transfer rate and mortality after transfer were significantly higher in LV institutions (respectively: 4.3% vs 2.5%, P < 0.0001; and 12% vs 10.3%, P < 0.0001). CONCLUSION: High volume centres have higher morbidity, but lower mortality. Six per cent of patients in LV centres required transfer. A national mortality rate after CRR of 3.5% can be expected. Transfer rate and mortality after transfer should be included in the evaluation of institutional mortality. Volume of institution, regardless of type, influences mortality after CRR.

Management of acute sigmoid volvulus: short- and long-term results.

AIM: The best form of prophylactic management of a decompressed sigmoid volvulus (SV) is controversial especially in the elderly. We have studied our experience with this condition to assess the short- and long-term results of SV management. METHOD: All patients treated for SV in our department between 2003 and 2013 were retrospectively included. Emergency decompression was attempted in all patients in whom there was no sign of peritonitis. Planned surgical resection was the procedure of choice in young patients. Percutaneous endoscopic colopexy (PEC) was used in high surgical risk patients. RESULTS: There were 65 patients (45 males) of median age 71.5 (24-99) years. Non-surgical reduction was performed in 62 with a success rate of 95% (59/62). Recurrence after initial decompression was 67% at a median follow-up of 5 (1-14) years. A prophylactic surgical resection was performed with primary anastomosis in 33 patients. There were no deaths and the major morbidity rate was 6%. At a mean follow-up of 62 months, only 1 (3%) patient had had a recurrence (at 130 months). PEC was performed in six patients of median age 90 (84-99) years and with a median American Society of Anesthesiologists score of 4. Complications included local site infection (n = 2), pain (n = 1) and abdominal wall bleeding (n = 1). After a median follow-up of 2 (1-4) years, three patients died from medical causes and one recurrence occurred 13 months after removal of the PEC tube. CONCLUSION: Prophylactic treatment after initial decompression of SV results in a low rate of recurrence. Planned sigmoid resection is safe and effective. In frail elderly patients, PEC is satisfactory.

Influence of bile duct obstruction on the results of Frey's procedure for chronic pancreatitis.

OBJECTIVES: To evaluate the influence of a biliary obstruction (BO) requiring biliary bypass on both short and long-term outcomes of patients undergoing Frey's procedure for chronic pancreatitis (CP). METHODS: From 1999 to 2010, 33 consecutive patients underwent Frey's procedure for CP in two centers. Seventeen (54%) patients underwent biliary bypass to treat an associated BO. Characteristics and outcomes of these patients were compared to those of 16 others without BO. RESULTS: Patients with BO had more severe disease including lower BMI and larger pancreatic head (4 cm vs. 6 cm, p = 0.021). The operative mortality was nil. Patients with BO experienced more overall postoperative complications (71% vs. 31%, p = 0.024) but similar major complication rates (18% vs. 6%, p = 0.316) compared to those without BO. After a median follow-up of 51 (1-96) months, 91% of the patients experienced either partial or complete relief of their symptoms and 36% exhibited deterioration of their endocrine function. Multivariate analysis revealed preoperative BO to be associated with long-term impairment of endocrine function (OR: 43.249; 95% CI 2.221-84.277; p = 0.013). CONCLUSION: In patients undergoing Frey's procedure for CP, associated BO can be safely managed using biliary bypass. However, the severity of CP in these patients is responsible for a higher risk of long-term endocrine insufficiency.

Immediate outcome, long-term function and quality of life after extended colectomy with ileorectal or ileosigmoid anastomosis.

AIM: Total/subtotal colectomy with ileorectal (IRA) or ileosigmoid (ISA) anastomosis is associated with various reported rates of morbidity, function and quality of life. Our object was to determine these end-points in a series of patients undergoing these operations in our institution. METHOD: All patients who underwent IRA or ISA between 1994 and 2009 were retrospectively reviewed. RESULTS: A total of 320 patients (female 49%) with a median age of 54.2 (16.8-90.6) years underwent 338 IRA or ISA (in 18 patients the anastomosis was done twice) for inflammatory bowel disease (n = 96), polyposis (n = 95) and colorectal cancer (n = 97). Mortality and morbidity rates were 1.2% (n = 4) and 19.5% (n = 66) and 47 surgical complications (13.9%) occurred, including 26 (7.7%) cases of anastomotic leakage, leading to 23 re-operations. After a median follow-up of 49 (0-196) months, 262 patients still had a functioning anastomosis; 45 patients had died and 13 had a proctectomy. Information on function was obtained in 51.4% (133/259) of the cohort after a median follow-up of 77 (10-196) months. The mean (± standard deviation) rates of 24 h and nocturnal defaecation were 3.6 ± 2.4 and 0.5 ± 0.9. A disturbance of faecal or flatus continence occurred in 20% and 21% of patients. There was no case of faecal incontinence to solid stool. The mean SF-36 Physical and Mental Health Summary Scales were 46.3 ± 9.3 and 51.9 ± 9.3. Multivariate analysis showed that IRA and inflammatory bowel disease were both independently associated with poorer long-term function. CONCLUSION: Colectomy with IRA or ISA is safe with low postoperative morbidity and mortality. The employment of IRA and inflammatory bowel disease appear to be independent negative factors on function in multivariate analysis.

Surgical resection of retrorectal tumours in adults: long-term results in 47 patients.

AIM: Retrorectal tumours (RT) are uncommon, and diagnosis and management remain difficult. The aim of this study was to evaluate the results of the surgical management of RT in our institution. METHOD: Medical notes of all patients operated on for RT were reviewed. Clinical, radiological, surgical, histological data as well as morbidity and long-term results were noted. RESULTS: Forty-seven patients [34 women (72%), mean age 45.8 (range 17-85) years] underwent surgery for RT between 1997 and 2011. The commonest symptoms were pain (n = 31) and suppuration (n = 10). Thirty-nine (83%) patients underwent preoperative magnetic resonance imaging (MRI). Malignant lesions exhibited typical characteristics on MRI including heterogeneity (n = 5, 83%), solid appearance (n = 4, 67%), a low-T1 signal and high-T2 intensity (n = 5, 83%), enhancement after gadolinium injection (n = 5, 83%), irregular margin (n = 4, 67%) and extension above S3 (i = 5, 83%). A Kraske approach was used in 42 (89%) patients with resection of the coccyx in 25 (60%) and an abdominal or combined approach for the remaining five. Four patients developed complications (two haematoma, two abscess), but only one (haematoma) required reoperation. Histological examination showed 38 (80.9%) benign lesions. After a median follow-up of 71 (2-168) months, 5-year disease-free survival was 75% for malignant lesions and 93.1% for benign lesions (P = 0.023). Four (4/42; 9.5%) patients had moderate perineal pain after a Kraske approach, while no anal dysfunction was seen. CONCLUSION: Magnetic resonance imaging was the most helpful investigation for retrorectal tumours. The posterior trans-sacrococcygeal approach is the procedure of choice for complete resection for most, especially for benign and cystic lesions without extension above S2.

Management of malignant left colonic obstruction: is an initial temporary colostomy followed by surgical resection a better option?

AIM: The surgical management of obstructed left colorectal cancer (OLCC) is still a matter of debate, and current guidelines recommend Hartmann's procedure (HP). The study evaluated the results of the surgical management with a focus on a strategy of initial colostomy (IC) followed by elective resection. METHOD: All patients operated on for OLCC were reviewed. Clinical, surgical, histological, morbidity and long-term results were noted. RESULTS: From 2000-11, 83 patients (48 men) with a mean age of 70.3 ± 15.1 years underwent surgery for OLCC. Eleven (13.3%) had a subtotal colectomy owing to a laceration of the caecal wall. Eleven had a HP for tumour perforation (n = 6) or as palliation in a severely ill patient (n = 5). The remaining 61 (73.5%) patients had an IC, with the intention of performing an elective resection shortly after recovery. Postoperative complications occurred in six (9.8%) and there were two (3.3%) deaths. Fifty-nine operation survivors had a colonoscopy shortly afterwards which showed a synchronous cancer in two (3.4%). Twelve of the 59 patients had synchronous metastases. The subsequent elective resection including the colostomy site could be performed in 45 (74%) patients during the same admission at a median interval of 11 (7-17) days. The overall median length of hospital stay was 20 days and the 30-day mortality was 3/61 (5%). CONCLUSION: IC followed by surgical resection is a technically simple strategy, allowing initial abdominal exploration with a short period of having a colostomy, and permitting elective surgery with a low morbidity and full oncological lymphadenectomy.

The effect of ursodesoxycholic acid on duodenal adenomas in familial adenomatous polyposis: a prospective randomized placebo-control trial.

AIM: Duodenal adenomas occur in about 90% of patients with familial adenomatous polyposis (FAP) and are the second cause of death of patients who have had a prophylactic proctocolectomy. Studies suggest that biliary acids have a role in the development of duodenal adenomas. The aim of this study was to evaluate the impact of ursodesoxycholic acid (UDCA) on duodenal adenoma formation in patients with FAP. METHOD: A randomized, double-blinded, placebo-controlled study was carried out of 71 patients (20-65 years) who already had a restorative proctocolectomy. Subjects received either 10 mg/kg of UDCA orally per day or a placebo tablet for 24 months. The Spigelman severity score was determined after duodenal axial and lateral view endoscopy at 12 and 24 months. RESULTS: At 2 years 55 patients had completed the entire period of treatment. At the end of the follow-up period, nine (25%) patients in the UDCA group and seven (20%) in the placebo group had a decrease in the Spigelman score (P = 0.6142). Patients receiving UDCA had no side-effects (0%) compared with four (14%) in the placebo group (P = 0.0392). CONCLUSION: UDCA had no effect on the development of duodenal adenomas in FAP patients (NCT: 00134758).

Frequent mutation in North African patients with MUTYH-associated polyposis.

MUTYH-associated polyposis (MAP) has been characterized as an autosomal recessive disease predisposing to a variable number of colorectal adenomas with a high risk of cancer. Numerous studies have indicated that two missense mutations (Y179C and G396D) account for about 80% of MUTYH allelic variants in Europeans. Ethnic and geographic differences in the mutation spectrum have been observed. The aim of this study was to report mutations in patients from North Africa, determine the incidence of the c.1227_1228dup mutation in our cohort of MUTYH patients and to evaluate the existence of a founder effect. Within a group of 36 families with MAP, 11 were shown to have a homozygous c.1227_1228dup mutation. These families came from Algeria (n = 5), Tunisia (n = 4), Morocco (n = 1) and Portugal (n = 1). Probands belonging to families of North African origin showed a significantly higher frequency of c.1227_1228dup (78.6% vs 4.5%, p < 0.0001). Haplotype analyses were performed using 10 microsatellite markers surrounding the MUTYH gene spanning a region of 4.4 cM. We identified a common haplotype of at least 1.3 cM in all families suggesting a founder effect for this mutation.

Female sexual function after abdominoperineal resection for squamous cell carcinoma of the anus and the specific influence of colpectomy and vertical rectus abdominis myocutaneous flap.

AIM: Abdominoperineal resection (APR) is the only curative treatment for recurrent or persisting squamous cell carcinoma of the anus after radiochemotherapy. A vertical rectus abdominis myocutaneous (VRAM) flap reduces perineal morbidity. The sexual life (SL) of women after APR is unknown. Aims of this study were to evaluate SF of women after APR. METHOD: 47 women alive after APR performed between 1996 and 2007 were included. SL was evaluated using the female sexual function index (FSFI) score. RESULTS: 29 (62%) women answered the questionnaire: 15 (52%) had a VRAM and 16 (55%) a colpectomy. Among the 21 patients with SL before surgery, 16 (76%) still had intercourse with a mean FSFI score of 19.5 ± 10.9 [4.8-36]. Main difficulties reported were troubles of lubrication, orgasm, and dyspareunia. Confection of a VRAM did not influence the recovery of SL (P = 0.717). Colpectomy reduced return of SL (P = 0.026). CONCLUSION: Among women who had SL before APR, 76% still had sexual intercourse after. Colpectomy seems to reduce SL.

Martius advancement flap for low rectovaginal fistula: short- and long-term results.

AIM: Many surgical approaches have been described for the treatment of low rectovaginal fistulae (LRVF); however, all are associated with a high recurrence rate and a poor function. The Martius flap technique was first described in 1928 and has since been modified for the treatment of LRVF. The aims of this study were to evaluate the short- and long-term results of the Martius flap procedure. METHOD: Twenty patients who underwent the Martius flap procedure between 2000 and 2010 were retrospectively included. Operative results and morbidity were evaluated. Quality of life (SF-12 score), quality of sexual life [Female Sexual Function Index (FSFI) score] and anal continence (Wexner score) were determined. RESULTS: Crohn's disease was the predominant aetiology (n = 8, 40%). The Martius flap was mostly harvested from the left side (n = 14, 66.7%). The morbidity rate was 15% (n = 3), and the mean hospital stay was 7.7 ± 3.7 days. At a mean follow up of 35 months, the success rate was 65%. Seven patients still had an LRVF: in patients with Crohn's disease the success rate was 50% (4/8). Fifteen patients (75%) answered the three questionnaires. Quality of life score was in the normal range: physical component summary score (PCS: 46.7 ± 9) and mental component summary score (MCS: 44.7 ± 11.3). The median (range) FSFI score was 5 (2-31.7). Eight patients (53%) deemed cured suffered no incontinence. The Wexner score was significantly higher in the presence of a persisting LRVF (2.6 ± 5.5 vs 13.4 ± 3.78) (P = 0.0018). Use of a right-sided flap was associated with a higher success rate (P = 0.0442). CONCLUSION: The Martius flap procedure for LRVF, had a success rate of about 60% and a low morbidity.

Antegrade colonic enema for faecal incontinence in adults: long-term results of 75 patients.

AIM: Faecal incontinence is a significant source of distress, and a permanent stoma is frequently offered to these patients. The antegrade colonic enema (ACE) procedure is an alternative approach to treat faecal incontinence. The long-term outcome remains unknown in adults with faecal incontinence. The aim of this study was to evaluate the long-term results of the ACE procedure for incontinence in adults and its impact upon quality of life. METHOD: All patients who underwent an ACE procedure between 1999 and 2009 were included. Clinical and demographic data and postoperative course were obtained from a review of medical records and databases. Each patient underwent a telephone interview. Quality of life was assessed using the GIQLI and SF36 scores, and faecal incontinence was evaluated using the Wexner score. RESULTS: Seventy-five patients (54 females; 72%) were included. An ileal neoappendicostomy was performed in 68 patients (90%). The mean hospital stay was 9 days (range 6-24 days). Early complications occurred in four patients and late surgical complications (after 3 months) were observed in 12 (16%) patients. At a median follow up of 48 months, 64 (91%) were still performing enemas, and treatment was judged to be successful in 55 (86%) of 64 patients. The Wexner score was 3.4 ± 2.4, showing a significant reduction when compared with the preoperative value (P < 0.0001). Quality of life scores were in the range of a control population. CONCLUSION: The ACE procedure is an effective long-term strategy in the treatment of faecal incontinence, with low and acceptable morbidity, and should be preferred before definitive colostomy.

Impact of p53 expression and microsatellite instability on stage III colon cancer disease-free survival in patients treated by 5-fluorouracil and leucovorin with or without oxaliplatin.

BACKGROUND: The aim was to determine the values of p53 tumour expression and microsatellite instability (MSI) phenotype to predict benefit from adjuvant chemotherapy of colon cancer by 5-fluorouracil and leucovorin (FL) alone or with oxaliplatin (FOLFOX). PATIENTS AND METHODS: This retrospective study included 233 unselected patients with stage III colon cancer treated by FL (n = 124) or FOLFOX (n = 109). The impact of p53 expression and MSI on disease-free survival (DFS) was defined using univariate and multivariate analyses. A Cox proportional hazards model was specifically designed to evaluate the interaction between chemotherapy and these genetic alterations. RESULTS: In univariate analyses, addition of oxaliplatin significantly improved DFS provided that tumour overexpressed p53 [hazard ratio (HR) 0.39; 95% confidence interval (CI) 0.19-0.82; P = 0.01] or displayed MSI phenotype (HR 0.17; 95% CI 0.04-0.68; P = 0.01). In multivariate analyses, p53 was confirmed as an independent factor predictive of benefit from FOLFOX (P = 0.03), while the interaction of MSI with chemotherapy could not be determined in the absence of relapse in the MSI group treated with FOLFOX. CONCLUSION: Our observations indicate that MSI status and p53 expression may influence the impact of oxaliplatin on adjuvant treatment of stage III colon cancer patients.

Sacral nerve stimulation for faecal incontinence: response rate, satisfaction and the value of preoperative investigation in patient selection.

OBJECTIVE: Before undergoing sacral nerve stimulation (SNS) for faecal incontinence (FI), patients are investigated with morphologic, dynamic and electrophysiologic tests. The purpose of our study was to evaluate their value in the selection of patients who may benefit most from neuromodulation. METHOD: If temporary stimulation resulted in a good objective response, a permanent neuromodulator was implanted. Patients were reviewed at 3 months and then at 6 monthly intervals. Asked by telephone, patient's satisfaction was described as good, satisfactory or poor. RESULTS: Forty-five consecutive patients (41 females, median age 59 years) with FI (Wexner 16.1 +/- 2.9) underwent SNS. Temporary stimulation was successful in 32 (71)% patients. At a median follow-up of 33 months, the neuromodulator remained in place in 25 (55%) patients, two do whom switched it off, leaving 23 (51%) with a functioning neuromodulator. There was no statistically significant difference between the characteristics (including manometry, ultrasound and electrophysiology) of patients undergoing implantation (n = 32) or not (n = 13) and those with or without a functioning stimulator (n = 23: n = 13). In the 23 patients with a functioning stimulator the result was good in 12, satisfactory in five and poor in six. There was no statistically significant difference in the patient characteristics between those with a good result (n = 12) and the remainder (n = 32). CONCLUSION: The findings suggest that investigation for FI does not facilitate patient selection for SNS and cannot be used to predict outcome.

Treatment of fistula-in-ano with the Surgisis(®) AFP(TM) anal fistula plug.

OBJECTIVE: Closure of the fistula tract with an anal fistula plug has been reported to provide success rates as high as 80%. The purpose of this study was to evaluate our results with this new method. METHOD: From June 2006 to September 2007, an anal fistula plug was used for the treatment of high transsphincteric fistulas. Success was defined as no residual leakage or abscess formation and closure of the external opening. RESULTS: Fifteen patients (seven women), median age 46 years (range 32-58 years), were included in the study. Three had Crohn's disease, three had an anovulvar fistula and seven had undergone previous surgical-repair attempts. Three patients expelled the prosthesis on postoperative day 2, 5 and 7, respectively, and a second plug placement was followed by expulsion again. One patient developed an abscess that was noted on postoperative day 4. The fistula tract healed in 6/15 patients (40%) after 3 months and in 8/15 (53.3%) after 7 months. The success rate in Crohn's disease was 33%. No significant difference was found between patients with or without previous surgical repair. CONCLUSION: In our experience, this simple technique provided success rates of 40% at 3 months and 53% at 7 months.

The management of perineal hernia following abdomino-perineal excision for cancer.

PURPOSE: Perineal hernia (PH) is a tardive complication following abdomino-perineal resection (APR). Many repair methods are described and evidences are lacking. The aim of this study was to report PH management, analyze surgery outcomes and review the available literature. METHODS: We retrospectively included all consecutive PH repair after APR performed between 2001 and 2017. We recorded data on APR surgery, PH symptoms and repair, and follow-up (recurrence and morbidity). Literature review included published articles on PubMed between 1960 and 2017. RESULTS: 24 PH repairs were included. The approach was perineal N = 16, abdominal N = 5 and combined N = 3. A biological mesh was used for 17, a synthetic for 5 and a flap for 2 patients. The median follow-up was 25 months. Overall morbidity was 37.5% (N = 9): 37.5% for the perineal, 20% for the abdominal, and 66.7% for the combined approach. Complications occurred in 35.3% of biological and 20% of synthetic mesh repairs. Recurrence rate was 41.7%, similar for biological (n = 8, 47.1%) and synthetic meshs (n = 2; 40%). No recurrence occurred in the flap group. Depending of the approach, we found 50% for perineal (n = 8) and 40% of the abdominal cohort (N = 2). Among twelve studies, recurrence rates ranged from 0 to 66.7%. Abdominal or laparoscopic approach with synthetic mesh was associated with less recurrences (0 and 12.5% respectively) and complications (37.5% and 9.5%). CONCLUSIONS: Recurrences following PH repair are high irrespective of the repair technique. More studies are necessary to identify PH risk factors and decide the appropriate perineal reconstruction.
