Long-term bowel functional outcomes following anal sphincter-preserving surgery for upper and middle rectal cancer: a single-center longitudinal study.

PURPOSE: Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients' quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer. METHODS: In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included. Bowel function was assessed longitudinally with Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores every 6 months after restoration of bowel continuity. Patients with at least 2 follow-up visits were included. RESULTS: Overall, 100 patients received neoadjuvant chemoradiotherapy. Urgency, soilage, and fecal incontinence were noted within 24 months in the patients treated with neoadjuvant chemoradiotherapy. After 2 years of follow-up, significant bowel dysfunction and fecal incontinence were observed in the neoadjuvant chemoradiotherapy group. Low tumor level and neoadjuvant chemoradiotherapy were associated with delayed bowel dysfunction. CONCLUSION: Neoadjuvant chemoradiotherapy in combination with low tumor level was significantly associated with delayed bowel dysfunction even after 2 years of follow-up. Therefore, careful selection and discussion with patients are paramount.

Multicenter validation of the PREDICT score for prediction of local recurrence after total mesorectal excision of rectal cancer.

BACKGROUND: Total mesorectal excision (TME) is the gold standard treatment for rectal cancer. Although TME has managed to decrease the rates of local recurrence after rectal cancer resection, local recurrence is still recorded at varying rates. The present study aimed to validate the PREDICT score in the prediction of local recurrence of rectal cancer after TME with curative intent. METHODS: This was a retrospective multicenter study on patients with nonmetastatic low or middle rectal cancer who underwent TME. The total PREDICT score was calculated for every patient and related to the onset of local recurrence. According to the final score, patients were allocated to one of three risk groups: low, moderate, and high, and the rates of local recurrence in each group were calculated and compared. RESULTS: The present study included 262 patients (50.4% males) with a mean age of 47.1 years. The overall local recurrence rate was 12.6%. 29.4% of patients were in the low-risk group, 63.7% in the moderate-risk group, and 6.9% in the high-risk group. The local recurrence rate was 3.9% (95% confidence interval [CI]: 0.8-10.9) in the low-risk group, 13.2% (95% CI: 8.4-19.3) in the moderate risk group, and 44.4% (95% CI: 21.5-69.2) in the high-risk group (p < 0.0001). The sensitivity of the PREDICT score was 72.7%, the specificity was 88.1%, and the accuracy was 86.3%. CONCLUSIONS: The PREDICT score had good diagnostic accuracy in the prediction of local recurrence after TME and a good discriminatory ability in the differentiation between patients at different risks to develop local recurrence.

Ultrasound-guided versus laparoscopic-guided subcostal transversus abdominis plane (TAP) block versus No TAP block in laparoscopic cholecystectomy; a randomized double-blind controlled trial.

BACKGROUND: Transversus abdominis plane (TAP) block is an effective modality for the control of immediate postoperative pain. The present randomized trial aimed to assess the efficacy of ultrasound-guided subcostal TAP (USTAP) and laparoscopic subcostal TAP (LSTAP) block as compared to standard care without TAP block after laparoscopic cholecystectomy. METHODS: This was a prospective, randomized, controlled trial on patients who underwent laparoscopic cholecystectomy. Patients were equally randomized to one of three groups: USTAP, LSTAP, and control group (no TAP block). The main outcome measures were pain scores and analgesic consumption within the first 24 h postoperatively, postoperative nausea and vomiting (PONV), time to ambulation, time to first flatus, and adverse effects of TAP block. RESULTS: The trial included 110 patients (90% females) with a mean age of 40.9 ± 11.7 years. Both USTAP and LSTAP block groups were associated with significantly lower pain scores at 2, 6, 12, and 24 h postoperatively, lower cumulative dose of paracetamol, less PONV, and shorter time to flatus than the control group. USTAP and LSTAP block were associated with similar pain scores at all time points, similar analgesic requirements, a similar incidence of PONV, and comparable time to first ambulation and time to first flatus. No adverse effects related to TAP block were recorded. CONCLUSIONS: TAP block is a safe and effective method for pain control and improving recovery after laparoscopic cholecystectomy. Both USTAP and LSTAP blocks were equally effective in terms of pain relief, analgesic requirements, PONV, return of bowel function, and time to ambulation.

Efficacy and Safety of Non-Operative Management of Uncomplicated Acute Appendicitis Compared to Appendectomy: An Umbrella Review of Systematic Reviews and Meta-Analyses.

BACKGROUND: Non-operative management (NOM) of uncomplicated acute appendicitis (AA) has been introduced as an alternative to appendectomy. This umbrella review aimed to provide an overview of the efficacy and safety of NOM of uncomplicated AA in the published systematic reviews. METHODS: This umbrella review has been reported in line with the PRISMA guidelines and umbrella review approach. Systematic reviews with and without meta-analyses on the efficacy of NOM of AA were analyzed. The quality of the reviews was assessed with the AMSTAR 2 tool. The main outcomes measures were the treatment failure and complication rates of NOM and hospital stay as compared to appendectomy. RESULTS: Eighteen systematic reviews were included to this umbrella review. Eight reviews documented higher odds of failure with NOM, whereas two reviews revealed similar odds of failure. Six reviews reported lower odds of complications with NOM, six reported similar odds, and one reported lower odds of complications with surgery. Eight reviews reported similar hospital stay between NOM and appendectomy, one reported longer stay with NOM and another reported shorter stay with NOM. Pooled analyses showed that NOM was associated with higher treatment failure overall, in children-only, adults only, and RCTs-only meta-analyses. NOM was associated with lower complications overall, yet children-only and RCTs-only analyses revealed similar complications to surgery. NOM was associated with shorter stay in the overall and adult-only analysis, but not in the children-only analysis. CONCLUSIONS: NOM of AA is associated with higher treatment failure, marginally lower rate of complications and shorter stay than appendectomy.

Neorectal Mucosal Prolapse After Intersphincteric Resection for Low-Lying Rectal Cancer: A Case Report.

Radical resection for low rectal cancer is the mainstay among the treatment modalities. Intersphincteric resection (ISR) is considered a relatively new but effective surgical treatment for low-lying rectal tumor. As the sphincter preserving techniques get popularized, we notice uncommon complication associated with it in the form of rectal mucosal prolapse. We presented 2 rare cases that developed neorectal mucosa prolapse after ISR a complication following low rectal cancer surgery. Although ISR is a safe and effective surgical technique for low rectal cancer, it should be considered to correct modifiable possible risk factors. Also, Delorme procedure is good option for management of neorectal mucosal prolapse.

Outcome of lateral pelvic lymph node dissection with total mesorectal excision in treatment of rectal cancer: A systematic review and meta-analysis.

BACKGROUND: Total mesorectal excision is the gold standard treatment of mid- and low-lying rectal cancer. Lateral pelvic lymph node dissection has been suggested as an approach to decrease recurrence and improve survival. Our meta-analysis presented here aimed to review the current outcomes of lateral pelvic lymph node dissection and total mesorectal excision in comparison with total mesorectal excision alone. METHODS: A systematic literature search querying electronic databases was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. We reviewed articles that reported the outcomes of lateral pelvic lymph node dissection combined with total mesorectal excision in comparison with total mesorectal excision alone. The main outcome measures were local recurrence, distant metastasis, overall and disease free-survival, and complications. RESULTS: This systematic review included 29 studies of 10,646 patients. Of those patients, 39.4% underwent total mesorectal excision with lateral pelvic lymph node dissection. The median operation time for the lateral pelvic lymph node dissection + total mesorectal excision was significantly longer than total mesorectal excision alone (360 minutes versus 294.7 minutes, P = .02). Lateral pelvic lymph node dissection + total mesorectal excision was associated with higher odds of overall complications (odds ratio = 1.48, 95% confidence interval: 1.18-1.87, P < .001) and urinary dysfunction (odds ratio = 2.1, 95% confidence interval: 1.21-3.67, P = .008) than total mesorectal excision alone. Both groups had similar rates of male sexual dysfunction (odds ratio = 1.62, 95% confidence interval: 0.94-2.79, P = .08), anastomotic leakage (odds ratio = 1.15, 95% confidence interval: 0.69-1.93, P = .59), local recurrence (hazard ratio = 0.96, 95% confidence interval: 0.75-1.25, P = .79), distant metastasis (hazard ratio = 0.96, 95% confidence interval: 0.76-1.2, P = .72), overall survival (hazard ratio = 1.056, 95% confidence interval: 0.98-1.13, P = .13), and disease-free survival (hazard ratio = 1.02, 95% confidence interval: 0.97-1.07, P = .37). CONCLUSION: Lateral pelvic lymph node dissection was not associated with a significant reduction of recurrence rates or improvement in survival as compared with total mesorectal excision alone; however, LPLND was associated with longer operation time and increased complication rate.

Does the timing of protective ileostomy closure post-low anterior resection have an impact on the outcome? A retrospective study.

BACKGROUND: The optimal timing for ileostomy closure remains controversial, most of the surgeons are closing ileostomy after two to three months, although ileostomy closure considered a simple procedure, it can cause significant morbidity; this study aims to clarify any relation between the post-closure complications rate and the time from its creation to the repair. METHOD: From January 2010 to December 2017, data retrieved for a 405 patients who had protective ileostomy closure after rectal cancer surgery, our sample has been enrolled into two arms, the first arm includes whose ileostomies closed at or before three months, and the second arm involved whose ileostomies closed after three months from the index surgery, statistical analysis was performed and compared in both arms, RESULT: The overall post-closure complications in our hospital was 23.7%, there was no significant difference between the overall complications rate for both early and late closure groups (26.8% and 22.7%) respectively (P = 0.499), The majority of the complications were intestinal obstruction, and superficial surgical site infection, there was no significant association between the interval to ileostomy reversal and the intestinal obstruction although it was higher in the late closure group, in the other hand the surgical site infection complication found to be significantly higher in the early closure group than the late closure group (15.4% Vs 5.1%) with (P = 0.002). CONCLUSION: The duration between the creation of protective ileostomy and its reversal was not a significant independent predictor of post-closure complications rate.

Assessment and management of low anterior resection syndrome after sphincter preserving surgery for rectal cancer.

Many patients develop a variety of bowel dysfunction after sphincter preserving surgeries (SPS) for rectal cancer. The bowel dysfunction usually manifests in the form of low anterior resection syndrome (LARS), which has a negative impact on the patients' quality of life. This study reviewed the LARS after SPS, its mechanism, risk factors, diagnosis, prevention, and treatment based on previously published studies. Adequate history taking, physical examination of the patients, using validated questionnaires and other diagnostic tools are important for assessment of LARS severity. Treatment of LARS should be tailored to each patient. Multimodal therapy is usually needed for patients with major LARS with acceptable results. The treatment includes conservative management in the form of medical, pelvic floor rehabilitation and transanal irrigation and invasive procedures including neuromodulation. If this treatment failed, fecal diversion may be needed. In conclusion, Initial meticulous dissection with preservation of nerves and creation of a neorectal reservoir during anastomosis and proper Kegel exercise of the anal sphincter can minimize the occurrence of LARS. Pre-treatment counseling is an essential step for patients who have risk factors for developing LARS.

Oncologic safety and bowel function after ultralow anterior resection with or without intersphincteric resection for low lying rectal cancer: Comparative cross sectional study.

BACKGROUND: Despite acceptable oncologic outcomes of sphincter preserving surgeries for low rectal cancer, bowel dysfunction occurs. This study aimed to compare the oncologic and functional bowel outcomes between ultralow anterior resection (ULAR) and intersphincteric resection (ISR) for low rectal cancer. METHODS: One hundred sixty-four patients who underwent ULAR with or without ISR for low rectal cancer between December 2010 and May 2018 were included. The Wexner and Memorial Sloan Kettering Cancer Center (MSKCC) scores were used to evaluate the bowel function of patients. Overall survival (OS) and disease-free survival (DFS) were compared between patients. RESULTS: The ISR group had higher incidence of major fecal incontinence than the ULAR group (75.9% vs 49.3%; P = .016). The median Wexner score decreased from 12 to 9 (P = .062) at 1-year follow-up. However, the frequency and urgency/soilage subscales of MSKCC score improved significantly in the ULAR group. ISR and follow-up interval less than 1-year significantly increased the major incontinence risk. The OS in the ULAR and ISR groups was 91.4% and 91.7%. Whereas the DFS in both groups was 79% and 79.2%, respectively. CONCLUSION: ULAR and ISR are comparable in oncologic outcomes. Severe bowel dysfunctions and major incontinence were noted in ISR group. Careful selection of patients is mandatory.

Single-center Experience of 24 Cases of Tailgut Cyst.

PURPOSE: Tailgut cysts are rare congenital or developmental lesions that arise from vestiges of the embryological hindgut. They are usually present in the presacral space. We report our single-center experience with managing tailgut cysts. METHODS: We conducted a retrospective analysis of 24 patients with tailgut cyst treated surgically at the Colorectal Surgery Department of Severance Hospital, Yonsei University, Seoul, South Korea, between 2007-2018. RESULTS: This study included 24 patients (18 females) with a median age of 51.5 years (range, 21-68 years). Ten cases were symptomatic and 14 were asymptomatic. Cysts were retrorectal in 21 patients. Cysts were below the coccyx level in 16 patients, opposite the coccyx in 6, and above the coccyx in 2. Cysts were supralevator in 5 patients, had a supra- and infralevator extension in 18 patients, and were infralevator in 1. Ten patients were managed using an anterior laparoscopic approach, 11 using a posterior approach, and 3 using a combined approach. Mean cyst size was 5.5 ± 2.7 cm. Postoperative complications were Clavien-Dindo (CD) classification grade II in 9 patients (37.5%) and CD grade III in 1 (4.2%). The posterior approach group showed the highest rate of complications (P = 0.021). Patients managed using a combined approach showed a larger cyst size (P < 0.001), longer operation times (P < 0.001), and a greater likelihood of tumor level above the coccyx (P = 0.002) compared to other approaches. The tumors of 2 male patients were malignant: 1 was a neuroendocrine tumor treated with radiotherapy, while the other was a closely followed adenocarcinoma. Median follow-up was 12 months (range, 1-66 months) with no recurrence. CONCLUSION: Tailgut cysts are uncommon but can cause perineal or pelvic pain. Complete surgical excision via an appropriate approach according to tumor size, location, and correlation with adjacent pelvic floor muscles is the key treatment.

Outcome of laparoscopic ventral mesh rectopexy for full-thickness external rectal prolapse: a systematic review, meta-analysis, and meta-regression analysis of the predictors for recurrence.

BACKGROUND: Laparoscopic ventral mesh rectopexy (LVMR) has proved effective in the treatment of internal and external rectal prolapse. The present meta-analysis aimed to determine the predictive factors of recurrence of full-thickness external rectal prolapse after LVMR. METHODS: An organized, systematic search of electronic databases including PubMed/Medline, Embase, Scopus, and Cochran library was conducted in adherence to PRISMA guidelines. Studies that reported the outcome of LVMR in patients with full-thickness external rectal prolapse were included according to predefined criteria. A meta-regression analysis and sub-group meta-analyses were performed to recognize the patient and technical factors that were associated with higher recurrence rates. RESULTS: Seventeen studies comprising 1242 patients of a median age of 60 years were included. The median operation time was 122.3 min. Conversion to open surgery was required in 22 (1.8%) patients. The weighted mean complication rate across the studies was 12.4% (95% CI 8.4-16.4) and the weighted mean rate of recurrence of full-thickness external rectal prolapse was 2.8% (95% CI 1.4-4.3). The median follow-up duration was 23 months. Male gender (SE = 0.018, p = 0.008) and length of the mesh (SE = - 0.007, p = 0.025) were significantly associated with full-thickness recurrence of rectal prolapse. The weighted mean rates of improvement in fecal incontinence and constipation after LVMR were 79.3% and 71%, respectively. CONCLUSION: LVMR is an effective and safe option in treatment of full-thickness external rectal prolapse with low recurrence and complication rates. Male patients and length of the mesh may potentially have a significant impact on recurrence of rectal prolapse after LVMR.

Transanal hemorrhoidal dearterialization (THD) versus stapled hemorrhoidopexy (SH) in treatment of internal hemorrhoids: a systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Although conventional hemorrhoidectomy proved effective in treatment of hemorrhoidal disease, postoperative pain remains a vexing problem. Alternatives to conventional hemorrhoidectomy as transanal hemorrhoidal dearterialization (THD) and stapled hemorrhoidopexy (SH) were described. The present meta-analysis aimed to review the randomized trials that compared THD and SH to determine which technique is superior in terms of recurrence of hemorrhoids, complications, and postoperative pain. METHODS: Electronic databases were searched for randomized trials that compared THD and SH for internal hemorrhoids. The PRISMA guidelines were followed when reporting this meta-analysis. The primary endpoint of the analysis was persistence or recurrence of hemorrhoidal disease. Secondary endpoints were postoperative pain, complications, readmission, return to work, and patients' satisfaction. RESULTS: Six randomized trials including 554 patients (THD = 280; SH = 274) were included. The mean postoperative pain score of THD was significantly lower than SH (2.9 ± 1.5 versus 3.3 ± 1.6). 13.2% of patients experienced persistent or recurrent hemorrhoids after THD versus 6.9% after SH (OR = 1.93, 95%CI = 1.07-3.51, p = 0.029). Complications were recorded in 17.1% of patients who underwent THD and 23.3% of patients who underwent SH (OR = 0.68, 95%CI 0.43-1.05, p = 0.08). The average duration to return to work after THD was 7.3 ± 5.2 versus 7.7 ± 4.8 days after SH (p = 0.34). Grade IV hemorrhoids was significantly associated with persistence or recurrence of hemorrhoidal disease after both procedures. CONCLUSION: THD had significantly higher persistence/recurrence rate compared to SH whereas complication and readmission rates, hospital stay, return to work, and patients' satisfaction were similar in both groups.

Gender-based analysis of the characteristics and outcomes of surgery for anal fistula: analysis of more than 560 cases / Análise baseada no sexo das características e desfechos de cirurgia para fístula anal: análise de mais de 560 casos

ABSTRACT Background: Fistula-in-ano commonly affects males more than females. Some differences in the characteristics of fistula-in-ano between both genders have been recognized, yet the impact of these differences on the outcomes of surgery for fistula-in-ano is still unclear. The present study conducted a gender-specific analysis aiming to assess the characteristics and the outcomes of surgery of fistula-in-ano in each gender. Patients and methods: The records of patients with fistula-in-ano were retrospectively reviewed and the following variables were extracted: patients' demographics, type of fistula-in-ano, position of the external opening, operation performed, incidence of recurrence and complications, particularly fecal incontinence. Gender-based analysis of the characters and outcomes of surgery for fistula-in-ano was performed. Results: 565 (491 males) patients of a mean age of 41.7 years were included. Females had a significantly higher percentage of low fistula-in-ano than males (70.2% vs. 50.3%, p = 0.002). Males had a significantly higher percentage of high trans-sphincteric fistula-in-ano (48.5% vs. 29.7%; p = 0.003). Anterior fistula-in-ano was more common in female patients (69% vs. 16.3%; p < 0.0001). Recurrence of fistula-in-ano was detected in 42 (7.4%) patients. Males had higher recurrence rate than females (7.9% vs. 4%; p = 0.34). Fecal incontinence developed in 1.7% of patients with higher incidence observed in females (4% vs. 1.4%). Conclusion: The majority of fistula-in-ano in males were posterior and high trans-sphincteric whereas most fistula-in-ano in females were low and anteriorly based. Despite the different characteristics of fistula-in-ano; no significant differences in the rates of fistula recurrence and fecal incontinence between males and females could be recorded.

RESUMO Background: A fístula anal comumente acomete mais os homens que as mulheres. Algumas diferenças nas características da fístula anal entre ambos os sexos têm sido reconhecidas, embora o impacto dessas diferenças nos desfechos da cirurgia para fístula anal ainda seja incerto. O presente estudo realizou uma análise específica para sexo, com o objetivo de avaliar as características e os desfechos da cirurgia de fístula anal em cada sexo. Pacientes e métodos: Os prontuários de pacientes com fístula anal foram revisados retrospectivamente e as seguintes variáveis foram extraídas: dados demográficos dos pacientes, tipo de fístula anal, posição da abertura externa, cirurgia realizada, incidência de recidiva e complicações, particularmente incontinência fecal. Realizou-se uma análise baseada no sexo dos sujeitos e desfechos da cirurgia para fístula anal. Resultados: Foram incluídos 565 pacientes (491 do sexo masculino) com idade média de 41,7 anos. As mulheres apresentaram uma porcentagem significativamente mais alta de fístula anal baixa do que os homens (70,2% vs. 50,3%, p = 0,002). Os homens tiveram uma porcentagem significativamente maior de fístula anal transesfincteriana alta (48,5% vs. 29,7%; p = 0,003). A fístula anal anterior foi mais comum em pacientes do sexo feminino (69% vs. 16,3%; p < 0,0001). A recorrência de fístula anal foi detectada em 42 (7,4%) pacientes. Os homens apresentaram maior taxa de recorrência do que as mulheres (7,9% vs. 4%; p = 0,34). A incontinência fecal desenvolveu-se em 1,7% dos pacientes com maior incidência observada no sexo feminino (4% vs. 1,4%). Conclusão: A maioria das fístulas anais no sexo masculino foi posterior e transesfincteriana alta, enquanto a maioria das fístulas anais no sexo feminino foi baixa e anterior. Apesar das diferentes características da fístula anal, não foi possível registrar diferenças significativas nas taxas de recorrência de fístula e incontinência fecal entre homens e mulheres.

Endoscopic pilonidal sinus treatment: a systematic review and meta-analysis.

BACKGROUND: Sacrococcygeal pilonidal disease (SPD) is a common surgical condition for which a multitude of surgical treatments have been described. The present review aimed to evaluate the efficacy and safety of a novel endoscopic procedure for the treatment of SPD. METHODS: An organized literature search was conducted. Electronic databases including PubMed/Medline, Scopus, Embase, and Cochrane library were searched for articles that assessed the endoscopic treatment for SPD. The main outcome parameters were failure of the technique including persistence and recurrence of SPD, postoperative complications and pain, time to complete healing, and time to return to work. RESULTS: Nine studies with a total of 497 patients were included. Mean age of patients was 24.8 years. Mean operation time was 34.7 min. The procedure was performed as day-case surgery in all studies. The mean Visual analogue score of pain within the first week was 1.35. Failure of the technique was recorded in 40 (8.04%) patients, 20 (4.02%) had persistent SPD and 20 (4.02%) developed recurrence. The weighted mean failure rate of the technique was 6.3% (95% CI 3.6-9.1). Mean weighted complication rate was 1.1% (95% CI 0.3-2.4). Mean time to complete healing was 32.9 days and mean time to return to work was 2.9 days. CONCLUSION: The endoscopic treatment of pilonidal sinus is a promising and safe method of treatment of SPD. The main advantages of the endoscopic treatment as compared to conventional surgery are the minimal postoperative pain, quick healing, and short time to return to work and daily activities.

A Systematic review and meta-analysis of the efficacy and safety of video-assisted anal fistula treatment (VAAFT).

BACKGROUND: Video-assisted anal fistula treatment (VAAFT) is a novel, minimally invasive technique for the treatment of fistula-in-ano (FIA). This review aimed to search the literature for the outcome of VAAFT regarding the recurrence and complication rates of the technique. METHODS: A systematic literature search was conducted in compliance with the PRISMA screening guidelines. PubMed/MEDLINE and Scopus were searched for articles reporting the outcomes of VAAFT procedure from inception through April 2017. The main outcomes were patients' characteristics, technical aspects, operation time, recurrence, and complication rates. RESULTS: Eleven studies (n = 788 patients) were included. The mean age of the patients was 39.5 years. 66.5% of patients had high or complex FIA and 18.4% underwent previous fistula surgery. The internal opening of the fistula was detected in 85.7% of patients. The mean operation time was 42 ± 14.2 min. The weighed mean rate of detection of internal opening was 93.3%. Recurrence occurred in 112 (14.2%) patients after a median follow-up of 9 months. Recurrence rates varied according to method of closure of internal opening from 15.3% after using staplers, 17.7% after suturing, to 25% after advancement flap. The weighted mean recurrence rate across the studies was 17.7%. The weighted mean complication rate was 4.8%. CONCLUSION: VAAFT may be considered an effective diagnostic tool and a safe method for the treatment of complex and high FIA attaining satisfactory outcome and acceptably low complications. Recurrence after VAAFT may be related to previous fistula surgery and the method of closure of the internal opening.

Predictive Factors for Small Intestinal and Colonic Anastomotic Leak: a Multivariate Analysis.

Anastomotic leak (AL) is a serious complication of intestinal surgery with various predisposing factors. This study aims to assess several risk factors associated with AL after small intestinal and colonic anastomoses through a multivariate analysis. Two hundred twenty-four patients (126 males) with intestinal anastomosis of a median age of 44 years were reviewed. Independent factors associated with AL were male gender (OR = 2.59, P = 0.02), chronic liver disease (CLD) (OR = 8.03, P < 0.0001), more than one associated comorbidity (OR = 5.34, P = 0.017), anastomosis conducted as emergency (OR = 2.73, P = 0.012), colonic anastomosis (OR = 2.51, P = 0.017), preoperative leukocytosis (OR = 2.57, P = 0.015), and intraoperative blood transfusion (OR = 2.25, P = 0.037). Predicative factors significantly associated with AL were male gender, CLD, multiple comorbidities, emergent anastomoses, colonic anastomoses, preoperative leukocytosis, and intraoperative blood transfusion.

Perineal resectional procedures for the treatment of complete rectal prolapse: A systematic review of the literature.

BACKGROUND AND AIM: Several procedures for the treatment of complete rectal prolapse (CRP) exist. These procedures are performed via the abdominal or perineal approach. Perineal procedures for rectal prolapse involve either resection or suspension and fixation of the rectum. The present review aimed to assess the outcomes of the perineal resectional procedures including Altemeier procedure (AP), Delorme procedure (DP), and perineal stapled prolapse resection (PSR) in the treatment of CRP. PATIENTS AND METHODS: A systematic search of the current literature for the outcomes of perineal resectional procedures for CRP was conducted. Databases queried included PubMed/MEDLINE, SCOPUS, and Cochrane library. The main outcomes of the review were the rates of recurrence of CRP, improvement in bowel function, and complications. RESULTS: Thirty-nine studies involving 2647 (2390 females) patients were included in the review. The mean age of patients was 69.1 years. Recurrence of CRP occurred in 16.6% of patients. The median incidences of recurrence were 11.4% for AP, 14.4% for DP, and 13.9% for PSR. Improvement in fecal incontinence occurred in 61.4% of patients after AP, 69% after DP, and 23.5% after PSR. Complications occurred in 13.2% of patients. The median complication rates after AP, DP and PSR were 11.1%, 8.7%, and 11.7%, respectively. CONCLUSION: Perineal resectional procedures were followed by a relatively high incidence of recurrence, yet an acceptably low complication rate. Definitive conclusions on the superiority of any procedure cannot be reached due to the significant heterogeneity of the studies.

Outcomes following repair of incarcerated and strangulated ventral hernias with or without synthetic mesh.

BACKGROUND: The use of synthetic mesh for ventral hernia repair under contaminated conditions is a controversial issue due to the considerable risk of surgical site infection (SSI). This study aimed to review the outcomes of repair of incarcerated and strangulated ventral hernias with or without synthetic mesh in compliance with established clinical guidelines regarding the incidence of SSI and hernia recurrence. METHODS: The records of patients with complicated ventral hernias who were treated with or without synthetic mesh repair were reviewed. Variables collected included the characteristics of patients and of ventral hernias, type of repair, and incidence of SSI and recurrence. RESULTS: One hundred twenty-two patients (56 males) of a mean age of 56 years were included. Fifty-two (42.6%) and 70 (57.4%) patients presented with incarcerated and strangulated ventral hernias, respectively. Sixty-six (54%) patients were treated with on-lay mesh repair, and 56 (46%) were managed with suture repair. Twenty-one patients required bowel resection. SSI was detected in eight (6.5%) patients. There was no significant difference between both groups regarding the incidence of SSI (7.5% for mesh group vs 5.3% for suture group). Recurrence occurred in seven patients. Median follow-up period was 24 months. The suture repair group had a significantly higher incidence of recurrence than the mesh group. Diabetes mellitus, previous recurrence, and intestinal resection were significant predictors for SSI. CONCLUSION: Following established guidelines, synthetic mesh repair of incarcerated and strangulated ventral hernias attained lower recurrence rate, comparable incidence of SSI, and higher rate of seroma formation than suture repair.
