Intracorporeal or extracorporeal ileocolic anastomosis after laparoscopic right colectomy: cost analysis of the Torino trial.

BACKGROUND: Intracorporeal (IIA) and extracorporeal anastomosis (EIA) are two well-established techniques for restoration of bowel continuity after laparoscopic right colectomy (LRC). Since no economic analysis comparing the two different anastomotic techniques has been performed yet, it is still unclear if IIA can reduce perioperative costs. The aim of the study was to compare costs of LRC with IIA or EIA for right-sided colon neoplasm. METHODS: This is a cost analysis of a single-institution double-blinded randomized controlled trial comparing the outcomes of LRC with IIA and LRC with EIA in patients with a right-sided colon neoplasm. All direct in-hospital costs related to patient's admission were recorded (intraoperative costs: operative room, surgical tools, blood units-postoperative costs: hospital stay, laboratory and microbiology analyses, diagnostic services, analgesic drugs and antibiotic therapy, blood units, reoperation-outpatient costs: post-discharge wound medications). This trial was registered with ClinicalTrials.gov, Number NCT03045107. RESULTS: A total of 140 patients were randomized and analyzed. Mean overall costs in the IIA group exceeded 349 € the mean overall costs of the EIA group (7926.87 ± 4617.23 € vs. 7577.45 ± 6131.17 €; P = 0.704). A mean extra charge of 608 € regarding total intraoperative costs was recorded in the IIA group (3058.84 ± 897.42 € vs. 2450.15 ± 558.90 €; P < 0.001). The cost of surgical instruments resulted in 542 € additional charge per patient in the IIA group compared to EIA group (1782.74 ± 541.26 € vs. 1240.55 ± 384.09 €; P < 0.001). The mean cost of operative room occupancy was comparable in IIA and EIA group: 1276.09 ± 514.94 € vs. 1209.60 ± 422.80 € (P = 0.405). No significant differences were observed in postoperative costs and in outpatient costs. CONCLUSION: This economic analysis showed that IIA and EIA after LRC had similar overall costs, even though there were intraoperative extra costs of IIA.

Risk factors for Low Anterior Resection Syndrome (LARS) in patients undergoing laparoscopic surgery for rectal cancer.

BACKGROUND: Total mesorectal excision (TME) represents the "gold standard" of rectal cancer surgery. In locally advanced lesions neoadjuvant treatments (e.g. radiotherapy-nRT, radio chemotherapy-cnRT) have been shown to improve TME oncological results, reducing local recurrences rate. Nevertheless, these treatments have significant functional consequences impacting patients' quality of life (QoL). The resulting syndrome is known as Low Anterior Resection Syndrome (LARS). The purpose of this work was to evaluate the association between risk factors and the development of LARS in a prospective series of laparoscopic sphincter-saving TME. METHODS: The study was conducted as a retrospective observational epidemiological study of a prospective database, including all patients undergoing laparoscopic anterior resection surgery for rectal cancer at our Unit from 1st January 2013 to 31st May 2018. The diagnosis of LARS was performed using the LARS Score. We classified risk factors in patient-related, pre-, intra- and post-operative factors. RESULTS: The sample included 153 consecutive patients. Forty-one were affected by "low" rectal cancer, 74 by "middle" rectal cancer, 38 by "high" rectal cancer. The prevalence of overall LARS (major LARS + minor LARS) in our series was 35.9% (55/153 cases). Association between nRT and overall/major LARS was significant (respectively p = 0.03 and 0.02). Distal localization of tumor was also significantly associated with LARS [overall LARS (p = 0.03), major LARS (p = 0.014)]. CONCLUSIONS: In our study, neoadjuvant radiotherapy and tumor localization resulted independent risk factors for LARS after laparoscopic sphincter-saving TME. Tumor localization in the "middle" and "high" rectum resulted a protective factor compared to the localization in "low" rectum.

Low Tenofovir Plasma Exposure in HIV Oral Pre-exposure Prophylaxis Recipients with Gastrointestinal Disorders.

Four pre-exposure prophylaxis (PrEP) users with gastro-intestinal disorders (sleeve gastrectomy, terminal ileitis, celiac disease or chronic diarrhea) and receiving oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) were included. Despite a self-reported high adherence, trough plasma tenofovir concentrations (after a supervised intake) were significantly lower than those observed in PrEP recipients without gastrointestinal disorders [21 (±9.1) vs. 138 (±85) ng/mL]. PrEP users with gastrointestinal disorders may need increased TDF doses or alternative prophylactic measures.

Tailoring the radiotherapy approach in patients with anal squamous cell carcinoma based on inguinal sentinel lymph node biopsy.

BACKGROUND AND OBJECTIVES: The aim of our study was to analyze the results of selective inguinal node irradiation in patients with anal cancer, based on the biopsy of the inguinal sentinel lymph node (SLN), in terms of local control and prognosis. METHODS: Records of patients with anal squamous cell carcinoma from January 2001 to December 2016 were retrospectively reviewed. Tc99 lymphoscintigraphy was performed in all the clinically inguinal negative patients, followed by radio-guided surgical removal of the inguinal SLN. All patients were treated with combined radiochemotherapy. In patients with negative sentinel nodes, the inguinal area was excluded in the radiotherapy field. RESULTS: A total of 123 patients, 76 females (61.8%), mean age 60.1 ± 12.19 years old, underwent intraoperative lymph node retrieval. The histological analysis showed metastasis in the SLN in 28 patients (22.8%). The mean follow-up was 43.44 ± 31.86 months. No inguinal recurrence was observed in patients with negative inguinal sentinel node(s). A statistically significant difference was observed for overall and disease-free survivals in a patient with positive and negative inguinal sentinel nodes. CONCLUSIONS: In patients with anal canal cancer, the exclusion of the inguinal regions from the radiotherapy field, in patients with negative SLN, does not compromise locoregional control nor prognosis.

Intracorporeal or Extracorporeal Ileocolic Anastomosis After Laparoscopic Right Colectomy: A Double-blinded Randomized Controlled Trial.

OBJECTIVES: The aim of the study was to determine whether there are clinically relevant differences in outcomes between laparoscopic right colectomy (LRC) with intracorporeal ileocolic anastomosis (IIA) and LRC with extracorporeal IA (EIA). BACKGROUND: IIA and EIA are 2 well-established techniques for restoration of bowel continuity after LRC. There are no high-quality studies demonstrating the superiority of one anastomotic technique over the other. METHODS: This is a double-blinded randomized controlled trial comparing the outcomes of LRC with IIA and LRC with EIA in patients with a benign or malignant right-sided colon neoplasm. Primary endpoint was length of hospital stay (LOS). This trial was registered with ClinicalTrials.gov, number NCT03045107. RESULTS: A total of 140 patients were randomized and analyzed. Median operative time was comparable in IIA versus EIA group {130 [interquartile range (IQR) 105-195] vs 130 (IQR 110-180) min; P = 0.770} and no intraoperative complications occurred. The quicker recovery of bowel function after IIA than EIA [gas: 2 (IQR 2-3) vs 3 (IQR 2-3) days, P = 0.003; stool: 4 (IQR 3-5) vs 4.5 (IQR 3-5) days, P = 0.032] was not reflected in any advantage in the primary endpoint: median LOS was similar in the 2 groups [6 (IQR 5-7) vs 6 (IQR 5-8) days; P = 0.839]. No significant differences were observed in the number of lymph nodes harvested, length of skin incision, 30-day morbidity (17.1% vs 15.7%, P = 0.823), reoperation rate, and readmission rate between the 2 groups. CONCLUSIONS: LRC with IIA is associated with earlier recovery of postoperative bowel function than LRC with EIA; however, it does not reflect into a shorter LOS.

Intraoperative air leak test reduces the rate of postoperative anastomotic leak: analysis of 777 laparoscopic left-sided colon resections.

BACKGROUND: The evidence supporting the use of the air leak test (ALT) after laparoscopic left-sided colon resection (LLCR) to test the colorectal anastomosis (CA) integrity aiming at reducing the rate of postoperative CA leakage (CAL) is not conclusive. The aim of this study was to challenge the use of ALT after elective LLCR. METHODS: It is a retrospective analysis of a prospectively collected database including all patients undergoing elective LLCR with primary CA and no proximal bowel diversion between January 1996 and June 2017. The decision to perform the ALT was based on the individual surgeon routine practice. A multivariate analysis was performed to identify independent risk factors for CAL. RESULTS: A total of 777 LLCR without proximal diversion were included in the analysis: the CA was tested in 398 patients (ALT group), while intraoperative ALT was not performed in 379 patients (No-ALT group). The two groups were similar in demographic characteristics, indication, and type of procedure. Intraoperative ALT was positive in 20 (5%) patients: a stoma was created in 14 (70%) patients, while 6 (30%) patients had a suture repair alone. Overall, postoperative CAL occurred in 32 patients (4.1%): the postoperative CAL rate was lower in ALT patients (2.5% vs. 5.8%, p = 0.025). A reoperation was needed in 87.5% of cases. No CAL occurred in the 20 patients with intraoperative positive ALT. Multivariate analysis showed that ASA score 3-4 (OR 5.39, 95% CI 2.53-11.51, p < 0.001) and male sex (OR 3.96, 95% CI 1.66-9.43, p = 0.002) were independent risk factors for postoperative CAL, while intraoperative ALT independently reduced the postoperative CAL rate (OR 0.40, 95% CI 0.18-0.88, p = 0.022). CONCLUSION: Intraoperative ALT allows to detect AL defects after LLCR that can be effectively managed intraoperatively, leading to a significant lower risk of postoperative CAL.

Dose to Pelvic Bone Marrow Defined with FDG-PET Predicts for Hematologic Nadirs in Anal Cancer Patients Treated with Concurrent Chemo-radiation.

PURPOSE: To investigate whether irradiated volume of pelvic active bone marrow (ACTBM) may predict decreased blood cells nadirs in anal cancer patients undergoing concurrent chemo-radiation. METHODS: Forty-four patients were analyzed and pelvic active bone marrow (ACTBM) was characterized employing 18FDG-PET. Dosimetric parameters on dose-volume histograms were correlated to nadirs with generalized linear modeling. RESULTS: ACTBM mean dose was significantly correlated to white blood cell (ß = -1.338; 95%CI: -2.455/-0.221; p = 0.020), absolute neutrophil count (ß = -1.651; 95%CI: -3.284/-0.183; p = 0.048), and platelets (ß = -0.031; 95%CI: -0.057/-0.004; p = 0.024) nadirs. Other dosimetric parameters were found to be correlated (ACTBM-V10,-V20,-V30and-V40). CONCLUSIONS: 18FDG-PET is able to define active bone marrow and may predict for decreased blood cells count nadirs.

Analysis of Early and Long-Term Oncologic Outcomes After Converted Laparoscopic Resection Compared to Primary Open Surgery for Rectal Cancer.

BACKGROUND: Laparoscopic rectal resection (LRR) for cancer is a challenging procedure, with conversion to open surgery being reported in up to 30% of cases. Since only a few studies with short follow-up have compared converted LRR and open RR (ORR), it is unclear if conversion to open surgery should be prevented by preferring an open approach in those patients with preoperatively known risk factors for conversion. The aim of this study was to compare early postoperative outcomes and long-term survival after completed LRR, converted LRR or ORR for non-metastatic rectal cancer. METHODS: A prospective database of consecutive curative LRRs and ORRs for rectal cancer was reviewed. Patients undergoing LRR who required conversion (CONV group) were compared with those who had primary open rectal surgery (OPEN group) and completed LRR (LAP group). A multivariate analysis was performed to identify predictors of poor survival. RESULTS: A total of 537 patients were included in the study: 272 in the LAP group, 49 in the CONV group and 216 in the OPEN group. There were no significant differences in perioperative morbidity, mortality and length of hospital stay between the three groups. Five-year overall survival and disease-free survival rates did not significantly differ between LAP, CONV and OPEN patients: 83.9 versus 77.8 versus 81% (P = 0.398) and 74.5 versus 62.9 versus 72.7% (P = 0.145), respectively. Similar 5-year OS and DFS rates were observed between patients who had converted LRR for locally advanced tumor or for non-tumor-related reasons: 81.2 versus 80.8% (P = 0.839) and 62.5 versus 63.7% (P = 0.970), respectively. Poor grade of tumor differentiation, lymphovascular invasion and a lymph node ratio of 0.25 or greater, but not conversion, were independently associated with poorer survival. CONCLUSION: Conversion to open surgery does not impair short-term outcomes and does not jeopardize 5-year survival in patients with rectal cancer when compared to primary open surgery.

Preoperative stoma site marking: a simple practice to reduce stoma-related complications.

BACKGROUND: To evaluate the incidence and identify the risk factors of stoma-related complications in a consecutive series of patients treated at a single institution. METHODS: For this retrospective analysis, the medical records of patients followed up at the stoma care centre of our institution over the last 16 years were reviewed. The primary end point was the incidence of stoma-related complications. Risk factors were tested using univariate and multivariate Cox proportional hazards models. RESULTS: Of a total of 1076 patients, 604 received a colostomy and 472 an ileostomy. In all, 1055 stoma-related complications were recorded in 797 patients. Univariate analysis identified the following risk factors for stoma-related complications: male sex (p = 0.032), emergency surgery (p = 0.010), open surgery (p < 0.001), and ileostomy creation (p = 0.004). Preoperative stoma site marking was noted to play a protective role (hazard ratio 0.739; 95% confidence interval 0.576-0.947; p = 0.017). Multivariate analysis confirmed male sex and ileostomy creation as risk factors (p = 0.030 and p = 0.013, respectively) and preoperative stoma site marking as an independent protective factor (p = 0.001). CONCLUSIONS: Stoma-related complications are quite common, especially when an ileostomy is present. Preoperative stoma site marking was noted to play a highly protective role not only in reducing the complication rate but also in improving the patients' quality of life.

Intensity-modulated radiation therapy with simultaneous integrated boost combined with concurrent chemotherapy for the treatment of anal cancer patients: 4-year results of a consecutive case series.

PURPOSE: To report the 4-year outcomes of a consecutive series of anal cancer patients treated with concurrent chemo-radiation delivered with intensity-modulated radiotherapy (IMRT), employing a simultaneous integrated boost (SIB) approach. METHODS: A consecutive series of 54 patients was enrolled between 2007 and 2013. Treatment schedule consisted of 50.4 Gy/28 fractions (1.8 Gy daily) to the gross tumor volume, while the elective nodal volumes were prescribed 42 Gy/28 fractions (1.5 Gy/daily) for patients having a cT2N0 disease. Patients with cT3-T4/N0-N3 tumors were prescribed 54 (T3) or 60 (T4) Gy/30 fractions (1.8-2 Gy daily) to the gross tumor volume; gross nodal volumes were prescribed 50.4 Gy/30 fr (1.68 Gy daily) if sized ≤ 3 cm or 54 Gy/30 fr (1.8 Gy daily) if > 3 cm; elective nodal regions were given 45 Gy/30 fractions (1.5 Gy daily). Chemotherapy was administered concurrently according to the Nigro's regimen. Primary endpoint was colostomy-free survival (CFS). Secondary endpoints were local control (LC), disease-free survival (DFS), cancer-specific survival (CSS), overall survival (OS), and toxicity profile. RESULTS: Median follow up was 32.6 months (range 12-84). The actuarial probability of being alive at 4 years without a colostomy (CFS) was 68.9% (95% CI: 50.3%-84.7%). Actuarial 4-year OS, CSS, DFS, and LC were 77.7% (95% CI: 60.7-88.1%), 81.5% (95% CI: 64%-91%), 65.5% (95% CI: 47.7%-78.5%), and 84.6% (95% CI: 71.6%-92%). Actuarial 4-year metastasis-free survival was 74.4% (95% CI: 55.5%-86.2%). Maximum detected acute toxicities were as follows: dermatologic -G3: 13%; GI-G3: 8%; GU-G3: 2%; anemia-G3: 2%; neutropenia-G3:11%; G4: 2%; thrombocytopenia- G3:2%. Four-year G2 chronic toxicity rates were 2.5% (95% CI: 3.6-16.4) for GU, 14.4% (95% CI: 7.1-28) for GI, 3.9% (95% CI: 1%-14.5%) for skin, and 4.2% (95% CI: 1.1-15.9) for genitalia. CONCLUSIONS: Our study shows the feasibility of IMRT in the combined modality treatment of anal cancer, with comparable results to the literature with respect to LC, sphincter preservation and survival. Acute toxicity is lower if compared to series employing standard techniques. Our results support the use of IMRT on a routine basis for the treatment of anal cancer.

Laparoscopic versus open resection for transverse colon cancer.

BACKGROUND: Previous large randomized controlled trials comparing laparoscopic (LR) and open resection (OR) for colon cancer have not specifically analyzed the outcomes in patients with transverse colon cancer. The aims of this study were to evaluate the feasibility and safety of LR transverse colon cancer resection and to compare our findings with the results available in the literature. METHODS: We performed a retrospective analysis of consecutive patients undergoing LR or OR for histologically proven adenocarcinoma of the transverse colon. RESULTS: A total of 123 patients were included in this study: 66 LR and 57 OR. Median operating time was similar in the two groups. Median blood loss was higher in the OR group, even though the difference was not statistically significant. The rate of conversion from LR to OR was 16.7 %. Return of bowel function occurred significantly earlier in the LR group. The incidence and severity of 30-day postoperative complications and mortality rates were similar in the two groups. The median hospital stay was significantly shorter in the LR group. There was a trend toward a greater number of lymph nodes harvested in the OR group than in the LR group, although the difference was not statistically significant. The time to first flatus and bowel movement was significantly earlier in the LR group. Five-year overall survival and disease-free survival rates were similar in the LR and OR groups (86.4 vs. 88.6 %, p = 0.770 and 80.4 vs. 77.3 %, p = 0.516, respectively). CONCLUSIONS: LR of transverse colon cancer is feasible and safe, with similar early short-term outcomes when compared to OR. Larger prospective comparative studies with long-term follow-up are needed to assess the oncological equivalence of the two approaches.

Laparoscopic versus open resection for colon cancer: 10-year outcomes of a prospective clinical trial.

BACKGROUND: Laparoscopic resection (LR) and open resection (OR) for colon cancer have similar oncologic outcomes at 5-year follow-up. However, results from studies with longer follow-up are limited. This study aimed to compare 10-year oncologic outcomes of LR and OR for non-metastatic colon cancer. METHODS: A prospective non-randomized trial comparing patients undergoing LR or OR for non-metastatic colon cancer at a single institution was conducted. Statistical analyses were performed on an ''intention-to-treat'' basis and by actual treatment. Kaplan-Meier curves were compared to analyze overall survival (OS) and disease-free survival (DFS). A multivariate analysis was performed to identify predictors of poor survival. RESULTS: The study included 304 colon cancer patients: 154 patients underwent LR and 150 underwent OR. Fifteen (9.7 %) had LR converted to OR. During a median follow-up period of 138 (range, 120-220) months, no significant differences were observed between LR and OR patients in 10-year OS and DFS rates: 87.2 % versus 78.7 % (P = 0.182) and 80.9 % versus 76.8 % (P = 0.444), respectively. Conversion to open surgery was associated with a non-significant reduction in OS and DFS. Stage-by-stage comparison showed no significant differences between the two groups. Both OS and DFS were similar between right colon and left-sided colon cancer patients. On multivariate analysis, pT4 cancer and a lymph node ratio of 0.20 or more were the only independent predictors of both OS and DFS. CONCLUSIONS: The 10-year follow-up results confirm the oncological effectiveness of the laparoscopic approach to non-metastatic colon cancer.

Surgical scar endometriosis.

Endometriosis is a common disorder in females of reproductive age. Surgical scar endometrioma after cesarean section develops in 1-2% of patients, and usually presents as a tender and painful abdominal wall mass. The diagnosis is suggested by pre or perimenstrual pelvic pain and is often established only by histology. In this retrospective observational cohort study, we reviewed the medical records of five patients with a histopathological diagnosis of scar endometriosis. A scar mass was found on a previous Pfannenstiel incision in four patients and in a median cesarean section in one patient. The mean age at diagnosis (38.6 years, median 38) was older than reported elsewhere. A histological examination of the surgical specimen confirmed the diagnosis of endometriosis in all cases. During the follow-up period (mean 34.6 months), local recurrence (n = 1) and pelvic recurrence (n = 1) were treated surgically. Surgery is the treatment of choice for surgical scar endometriosis. Excision with histologically proven free surgical margins of 1 cm is mandatory to prevent recurrence. As scar endometriosis may be associated with pelvic localization, explorative abdominal laparoscopy may be indicated to exclude the intraperitoneal spread of the disease in symptomatic patients.

Transrectal sentinel lymph node biopsy for early rectal cancer during transanal endoscopic microsurgery.

BACKGROUND: Local excision of invasive cancer by transanal endoscopic microsurgery (TEM) entails the risk of lymphnode metastases that obliges to radical surgery. A determination of metastatic lymph-nodes would avoid major surgery in the vast majority of cases. We applied the concept of sentinel lymphnode (SLN) biopsy to suspected invasive rectal cancers treated by TEM. METHODS: Indocyanine green (ICG) is injected in the submucosa underneath the lesion. The tumor is dissected full-thickness until the perirectal fat. A near infra-red (NIR) optic provides a map of mesorectal lymphatics, on which guide the perirectal fat is dissected and lymph-nodes are excised. RESULTS: The technique was tested in three patients. In all cases the pathologist confirmed presence of lymphnodes in the excised tissue, no case showed metastasis. In all cases final pathology of the rectal neoplasm did not indicate radical surgery. CONCLUSION: In suspected invasive cancers, SLN mapping could be a useful technique to identify the first lymph node receiving drainage from the tumour, whose accurate pathological examination could predict the status of the remaining nodes and indicate further radical surgery. An ongoing study on a prospective case series will assess sensitivity and negative predictive value of SLN biopsy.

Metastatic lymph node ratio as a prognostic factor after laparoscopic total mesorectal excision for extraperitoneal rectal cancer.

BACKGROUND: The lymph node ratio (LNR; number of positive nodes divided by total nodes harvested) has been demonstrated to be a prognostic factor in colon cancer, but its role in extraperitoneal rectal cancer is still debated; furthermore, no data are available on laparoscopic rectal resection. The aim of this study was to evaluate the prognostic impact of LNR on long-term outcomes after laparoscopic total mesorectal excision (LTME) for extraperitoneal cancer in consecutive patients with a 5-year minimum follow-up. METHODS: This study is a prospective analysis of consecutive patients who underwent LTME for adenocarcinoma of the extraperitoneal rectum. RESULTS: LTME was performed in 158 patients. The median number of LN harvested was 12 (range = 3-25). The proportion of specimens with fewer than 12 examined LN was significantly higher in patients who had neoadjuvant chemoradiotherapy (p < 0.001). During a median follow-up period of 122 months, the local recurrence rate was 8 %. At univariate analysis, disease-free survival and overall survival significantly decreased with increasing LNR (p < 0.001). Multivariate analysis showed that the distal margin ≤ 1 cm was the only independent predictor of local recurrence (p = 0.028). LNR (cutoff value = 0.25) and lymphovascular invasion were significant prognostic factors for both disease-free (p = 0.015 and p = 0.046, respectively) and overall survival (p = 0.031 and p = 0.040, respectively). Even in the subgroup of patients in whom fewer than 12 LN were examined, LNR confirmed its prognostic role, with a statistical trend toward worse disease-free survival and overall survival. CONCLUSION: Metastatic LNR is an independent prognostic factor for disease-free survival and overall survival after LTME for extraperitoneal rectal cancer.

Topical treatment of anal condylomata with Propionibacterium acnes lysate: results of a multicentric observational study.

BACKGROUND: Condylomata are a manifestation of HPV infection of the ano-genital epithelium. Recurrence is frequent after any type of treatment (from 20% up to 50%). We assessed the use of a gel containing panthenol, tocopheryl acetate and Propionibacterium extract in the treatment of anal warts. METHODS: Enrollment period was from January 15 to June 15, 2018. Main exclusion criteria were immunodepression, extensive condylomatosis and other treatments (topical/ablative) in the previous six months. RESULTS: Seventy-nine patients were included. Median age was 33 years (19-65), 72.2% were males. Median number of partners and symptoms duration were 6 (1-98) and 3 months (1-18), respectively. Almost all cases had perianal disease (97.5%), while endoanal warts were present in 51.9% of cases. After 30 days of treatment, complete regression occurred in 17 (21.5%) patients, while partial or absent response was reported in 36 (45.6%) and 26 (32.9%) cases, respectively. Forty-seven (59.5%) patients underwent a second month of topical therapy. After a 6-month follow-up, complete or partial response was reported in 53 (67.1%) patients, while in 26 (32.9%) cases the disease remained stable or even worsened. Nineteen (24.1%) patients required cryotherapy, 23 (29.1%) surgical excision, while 2 (2.5%) needed both cryotherapy and surgery. Absence of clinical response was associated with a number of partners ≥10 and symptoms duration of 6 months or shorter (P<0.001 and P=0.050). CONCLUSIONS: In our study, the gel containing P. acnes lysate was a safe topical treatment for perianal and endoanal condylomata and could help to overcome HPV infection. A high number of partners and short symptoms duration appeared to worsen the outcome.

Perineal stapled prolapse resection for complete external rectal prolapse: preliminary experience and literature review.

PURPOSE: Perineal stapled prolapse resection (PSP) for external rectal prolapse is a new surgical technique. METHODS: Between April 2009 and January 2011, 5 female patients (mean age, 67 years; range, 53-76) underwent PSP for full-thickness external rectal prolapse. Patients were placed in a slight Trendelenburg position to free the pouch of Douglas from any deep enterocele. Laparoscopic control of the PSP procedure was performed to avoid injury to the bowel in one patient with anorexia. The prolapse was completely resected continuously counterclockwise using a curved Contour® Transtar™ stapler placed parallel to the dentate line. After completion of resection, the neorectum fell back into place spontaneously. RESULTS: Mean operating time was 56 min (range, 40-90). No intraoperative or postoperative complications occurred. No recurrence appeared. The mean hospital stay was 4 days (range, 3-6); the mean follow-up was 6.5 months (range, 2-15). The mean Wexner fecal incontinence score was 9.2 before and 4.6 at 3 months after surgery (p = 0.010); the mean obstructed defecation syndrome score decreased from 16 to 4.75 (p < 0.001). CONCLUSIONS: PSP is an easy, fast and safe procedure. Early functional results are good. Long-term results and recurrence rates need to be investigated further.

Management of Hemorrhoidal Disease in Special Conditions: A Word of Caution.

BACKGROUND: Hemorrhoids are a common disease that is often considered an easy problem to solve. Unfortunately, some particular clinical conditions, including Inflammatory Bowel Diseases (IBD), pregnancy, immunosuppression, coagulopathy, cirrhosis with portal hypertension, and proctitis after radiotherapy, challenge hemorrhoids management and the outcomes. METHODS: Research and online contents related to hemorrhoids' treatment in special conditions are reviewed in order to help colorectal surgeons in daily practice. RESULTS: There are very limited data about the outcomes of hemorrhoids treatment in these subgroups of patients. Patients in pregnancy can be effectively treated with medical therapy, reserving surgical intervention in highly selected and urgent cases. In case of thrombosed haemorrhoids, the excision allows a fast symptoms' resolution, with a low incidence of recurrence and a long remission interval. In case of immunosuppressed patients, there is no consensus for the best treatment, even in most HIV positive patients, a surgical procedure can be safely proposed when indicated. There is no sufficient data in the literature related to transplanted patients. The surgical treatment of hemorrhoids in patients with IBD, especially Crohn's Disease, can be unsafe, although there is a paucity of literature on this topic. In case of previous pelvic radiotherapy, it must always be considered that severe complications, like abscesses and fistulas with subsequent pelvic and retroperitoneal sepsis, can occur after surgical treatment of hemorrhoids, so a conservative treatment is advocated. Moreover, caution is recommended in treating patients with coagulopathy, considering possible complications (mostly bleeding) also after outpatient treatments. In case of portal hypertension and cirrhosis, a 'conservative treatment' is recommended. Bleeding hemorrhoids can be treated with hemorrhoidectomy when they do not respond to other treatments. CONCLUSION: International literature is very scant about the treatment of patients affected by hemorrhoids in particular situations. A word of caution and concern even about the indication for minor outpatient procedures must be expressed in these patients, in order to avoid possible life-threatening complications. The first-line treatment is the conservative medical approach associated with the treatment of the primary disease.
