Abstract

Objective: Unusual clinical course Background: Anal squamous cell carcinoma (SCC) is a rare cancer commonly treated with the Nigro protocol, which combines chemotherapy and radiation. Patients who received radiation therapy prior to modern advances, such as computer-based tumor targeting, volumetric planning, and intensity-modulated radiation therapy, experience more acute and chronic adverse effects. Though exceedingly rare, radiation necrosis is of particular concern, as it can result in significant morbidity and mortality, including complex pelvic fistula formation and predisposition to potentially life-threatening necrotizing soft-tissue infections. Case Report: Here, we present a case of a 66-year-old woman with a prior history of anal SCC stage T3N×M0 who was treated with the Nigro protocol. Her treatment course was complicated by radiation proctitis, necessitating fecal diversion and ureteral strictures, requiring frequent stent exchanges. She presented 18 years after her cancer treatment, with widespread necrosis of her pelvic organs and surrounding soft tissue, resulting in formation of a large pelvic "cloaca", with a superimposed necrotizing soft-tissue infection. She was successfully treated by expedited resuscitation, septic source control, using multiple extensive debridements, and complete urinary diversion, utilizing a multidisciplinary team. Conclusions: This case highlights the importance of monitoring patients for signs of radiation toxicity, particularly in patients who received radiation prior to the latest technological advancements, as they are at increased risk of developing severe, late adverse effects decades after treatment. When these complications are recognized, early and aggressive intervention is required to spare the patient significant morbidity and mortality. [ABSTRACT FROM AUTHOR]

34. Anal Resting Pressures at Manometry Correlate with the Fecal Incontinence Severity Index and with Presence of Sphincter Defects on Ultrasound

Author

Abstract

Abstract: Introduction: We describe the relationship between anorectal manometry, fecal incontinence severity, and findings at endoanal ultrasound. Methods: A total of 351 women completed the Fecal Incontinence Severity Index, underwent anorectal manometry, and endoanal ultrasound. Severity index and manometry pressures in 203 women with intact sphincters on ultrasound were compared with pressures in 148 women with sphincter defects. Relationships between resting and squeeze pressures, severity index, and size of sphincter defects were evaluated. Results: Mean severity index in patients with and without sphincter defect was 35.7 vs. 36.7 (not significant). Worsening index correlated with worsening mean and maximum resting pressure (P < 0.0001). Differences were observed in mean and maximum resting pressure between the patients with and without sphincter defects (26.6 vs. 37.2, P < 0.0001; 39.4 vs. 51.7, P < 0.001). Resting pressures correlated with the sizes of defect (P < 0.0001). Conclusions: Patients with and without sphincter defects had similar severity scores, but patients with defects had a significant decrease in resting pressures. Patients with larger sphincter defects had lower severity scores and resting pressures. Until a manometry cutoff can be set to discriminate between absence and presence of defects, both manometry and ultrasound should be offered to patients with history of anal trauma.

35. Treatment of Complex Anal Fistulas with the Collagen Fistula Plug

Abstract

Abstract: Purpose: Anal fistulas that involve a significant amount of sphincter may be difficult to treat without compromising continence function. In this study, we evaluated our experience with the Surgisis® anal fistula plug, which was recently reported to be successful in >80 percent of patients with complex fistulas. Methods: We retrospectively collected patient and fistula characteristics, procedure details, and follow-up information for all patients treated with the anal fistula plug at our institution from January 2006 through April 2007. The outcome was considered successful if the external opening was closed and if the patient had no drainage at the last follow-up. Using multivariate statistics, we analyzed the relationship between anal fistula plug success and several key variables. Results: From January 2006 through April 2007, 47 patients with 49 complex anal fistulas underwent 64 anal fistula plug procedures. The median follow-up time for patients who were considered healed was 6.5 (range, 3–11) months. The success rate was 31 percent per procedure and 43 percent per patient. An increased amount of external sphincter involvement was associated with a higher failure rate (P < 0.05). Conclusions: In our early experience with the anal fistula plug, 43 percent of patients with complex anal fistulas were successfully treated. Patients with less external sphincter involvement were more likely to heal.

Abstract

Perineal defects following abdominoperineal resections (APRs) for rectal cancer may require myocutaneous or omental flaps depending upon anatomic, clinical and oncologic variables. However, studies comparing their efficacy have shown contradictory results. We aim to compare postoperative complication rates of APR closure techniques in rectal cancer using propensity score-matching. The American College of Surgeons Proctectomy Targeted Data File was queried from 2016 to 2019. The study population was defined using CPT and ICD-10 codes for patients with rectal cancer undergoing APR, stratified by repair technique. Perioperative demographic and oncologic variables were controlled for by propensity-score matching. Multivariate logistic regression analysis was performed for wound and major complications (MCs). Of the 3291 patients included in the study, 85% underwent primary closure (PC), 8.3% rectus abdominis myocutaneous (RAM) flap, 4.9% pedicled omental flap with PC, and 1.9% lower extremity (LE) flap repair. Primary closure rates were significantly higher for patients with stage T1 and T2 tumors (p < 0.001). RAM and LE flaps were most used with multi-organ resections, 24% and 25%, respectively (p < 0.001). Similarly, cases with T4 tumors used these flaps more frequently, 30% and 40%, respectively (p < 0.001). After propensity score matching for comorbidities and oncologic variables, there was no significant difference in 30-day postoperative wound or MC rates between perineal closure techniques. The complication rates of the different closure techniques are comparable when tumor stage is considered. Therefore, tumor staging and concurrent procedures should guide clinical decision making regarding the appropriate use of each technique. [ABSTRACT FROM AUTHOR]
