Nigam, Siddhartha Nigam","doi":"10.4103/1941-8213.305937","DOIUrl":"https://doi.org/10.4103/1941-8213.305937","url":null,"abstract":"Background: Fistula-in-ano is known for its recurrence and other complications after surgery, especially in high fistulae cases. Use of a cutting seton is an accepted mode of treatment for high fistula-in-ano cases. Nigam′s modified Roeder′s knot (NMRK) makes the cutting seton adjustable. The aim of our study is to investigate the results of NMRK application in cutting seton in relation to reapplication, rethreading, postoperative inconvenience to the patient, and postoperative complications. Objectives: To determine whether the NMRK in cutting seton reduces the chances of seton reapplication and postoperative complications in high fistula-in-ano. Design: Squire---Quality Improvement Study. Setting: Patients admitted in various hospitals in Gurugram, Haryana, India. Materials, Methods, and Main Outcome Measures: Eighty high fistula-in-ano patients underwent fistulactomies using the NMRK in both the cutting and adjustable setons between January 2001 and January 2019. Informed consent was obtained from each patient. The patients were evaluated for seton reapplication, inconvenience, recurrence, fecal incontinence, and other postoperative complications. Sample Size: Eighty high fistula-in-ano patients underwent fistulactomies using the NMRK in both the cutting and adjustable setons Results: In our series, no patient suffered fecal incontinence. Three patients (3.75%) had gas incontinence, which gradually stopped within 2 weeks. Most of the setons took 4– 6 weeks to drop. The healing time was 6– 8 weeks for majority of the patients. Two patients (2.50%) developed recurrence after surgery. No patient required readmission or anesthesia for seton reapplication. Conclusion: If the cutting seton with the NMRK is retightened every week, then the drop time of the seton and the total healing time decrease, resulting in reduced incidence of inconvenience, pain, fecal incontinence, and recurrence. Rethreading or reapplication of seton is not required. Limitations: Our study includes only uncomplicated high fistula-in-ano cases. It also excludes complex fistulae, watercan perineum, and fistulae with inflammatory bowel disease or cancer. Conflict of Interest: None.

Traditionally, an open Hartmann′s reversal (OHR) has been performed but there is a trend toward performing laparoscopic Hartmann′s reversal (LHR). With the increasing number of publications comparing these two, it is important to ascertain whether the benefits of LHR outweigh the risks. Objective: To compare LHR and OHR with respect to morbidity and mortality rates. Design: A systematic review and meta-analysis. Setting: The study was conducted at the Peter MacCallum Cancer Centre in Melbourne, Australia. Patients and Methods: A detailed systematic search was performed through PubMed, SCOPUS, TRIP, EMBASE, and ClinicalKey from 1990 to October 26, 2016. A review was undertaken in accordance with PRISMA guidelines. Main Outcome Measures: The primary outcome measure was 30-day morbidity. Secondary outcome measures included estimated intraoperative blood loss, conversion from laparoscopic to open approach, length of hospital stay, and 30-day mortality. Sample Size: Eighteen eligible studies were identified, comprising a total of 7824 patients: 1586 in the laparoscopic group and 6238 in the open group. Results: There was no statistical difference in mean operative time between the two groups. Overall morbidity was lower in the LHR group (16.8% vs 23.7%, P < 0.0001). Subgroup-analysis showed a higher risk of sepsis (6.5% vs 3.2%; P < 0.0001), wound infection (22.5% vs 12.6%; P < 0.0001), and ileus (13.4% vs 5.5%; P = 0.001) in the OHR group. Conclusion: LHR was associated with a lower morbidity rate and shorter hospital stay with an equivalent operative time. There is a moderate rate of conversion and appropriate case selection is important. Limitations: An absence of prospective or randomized trials comparing the two approaches for Hartmann′s reversal, contributing to selection bias in our study.

Magnetic resonance imaging (MRI) is the gold standard for staging; however, its role for assessing response to neoadjuvant therapy is less than clear. Objective: To assess the role of restaging MRI post neoadjuvant long-course chemoradiotherapy (NA CRT) for locoregionally advanced rectal cancer. Design: A retrospective audit of prospectively collected data. Setting: A tertiary hospital colorectal unit. Patients and Methods: Patients with locoregionally advanced rectal adenocarcinoma (T3/T4 and/or nodal disease), who underwent restaging pelvic MRI scans post-NA CRT were included. Medical records of relevant radiology and operative histopathology were reviewed. Main Outcome Measures: To determine whether restaging MRI altered subsequent patient management (compared to the initial plan as documented in the pretreatment colorectal multidisciplinary team meeting). Sample Size: Twenty-three patients with restaging MRI. Results: On diagnosis, 15 patients (65.2%) had American Joint Committee on Cancer (AJCC) stage-III disease; two patients had AJCC stage-II disease (8.7%), and five patients (21.7%) had AJCC stage-IV disease with limited metastases (curative intent to treatment). Three patients had a complete clinical response (cCR) post NA CRT. Fourteen tumors had downstaging (MRI tumor regression grade 2-3, 58.3%). In three patients (13.0%), restaging MRI altered patient management. Two of them had extensive disease that underwent significant downstaging, enabling avoidance of a pelvic exenteration; and one also had sufficient downstaging and was able to have a sphincter preserving operation as a result. Conclusions: MRI may have a role in patients with the extensive locoregional disease or in ultralow rectal cancers where it is unclear if sphincter preservation is possible. Limitations: Small sample size; additionally, “watch and wait” methods are not routinely practiced in this tertiary unit.

This report documents a case of steroid-refractory, pembrolizumab-induced colitis managed with vedolizumab in a male with previously diagnosed stage-IIIb lung adenocarcinoma. The report raises the possibility of an increased risk of colonic metastasis with vedolizumab use and the potential need for closer monitoring and surveillance in patients with a history of active or recent malignancy.

Stapled transanal rectal resection (STARR) is one of the surgical options for ODS. Objectives: This study evaluates short-term and long-term functional outcomes following STARR for ODS patients and predictive factors determining the outcome of the surgery. Design: Retrospective analysis of prospectively collected data. Setting: This study was conducted in the colorectal unit of a tertiary hospital in Mumbai, India. Patients and Methods: Patients who underwent STARR surgery for ODS from January 2009 to January 2013 were evaluated. Patients were periodically followed up for 5 years. Main Outcome Measures: Longo scores and patient satisfaction were periodically evaluated in the 5-year follow-up. Sample Size: 204 patients. Results: 204 patients (M:F = 133:71, mean age 54.2 years) were evaluated. The mean preoperative Longo score was 23.2 ± 4.1. The mean operative time was 40 min and the median hospital stay was 2.1 days. On follow-up at 3 months symptoms improved in 92% patients, at 12 months symptoms persisted or recurred in 15% patients. Mean Longo scores at 12 months, 3 years, and 5 years follow-up was 7.14, 10.25, and 16.41 respectively. Patient satisfaction rate showed a declining trend in relation to time.

In addition, the role of restaging scans post-neoadjuvant therapy is still poorly established. Objectives: To examine current practice in the preoperative management of locally advanced rectal cancer in Australasia and determine the value of restaging magnetic resonance imaging (MRI). Design: Cross-sectional study (survey). Setting: Specialist colorectal surgeons in Australia and New Zealand. Participants and Methods: A web-based survey was distributed to the Colorectal Surgical Society of Australia and New Zealand (CSSANZ) members between December 2016 and February 2017. Information on demographics, imaging modalities used for staging, indications and choice of neoadjuvant therapy, as well as utility and perceived value of restaging MRI after neoadjuvant therapy was collected. Respondents were given hypothetical scenarios to assess their management decisions based on the findings of restaging MRI scans. Sample Size: 225. Main Outcome Measures: Preferred imaging modalities for staging and restaging of rectal cancer post-neoadjuvant therapy; indications and preferred regimen for neoadjuvant therapy; and utility and perceived value of restaging scans, particularly MRI, Results: Sixty-two (27.6%) CSSANZ members responded. Main neoadjuvant therapy indications included advanced T3 tumors (80.7% for T3c; 83.9% for T3d), T4 tumors (87.1%), nodal metastases (69.4% for N1; 77.4% for N2), and an involved circumferential resection margin (CRM) (95.2%). Long-course chemoradiotherapy was preferred for neoadjuvant therapy (80.6%). The preferred initial-stage imaging modalities were MRI (100%) and computed tomography of chest, abdomen, and pelvis (CT-CAP) (100%). Fifty-six (90.3%) respondents would perform restaging scans post neoadjuvant therapy in selected patients. An involved CRM was frequently identified as a feature on restaging MRI which may affect management (78.6%), with extramural venous invasion (EMVI) (7.1%) or tumor regression grading (TRG) (26.8%) rated less significant. Conclusion: Preoperative management of locally advanced rectal cancer in Australasia is generally consistent with current guidelines. Restaging MRI after neoadjuvant therapy undoubtedly has a role for guiding patient management, but larger prospective studies are warranted to firmly establish their place in daily clinical practice. Limitations: Poor response rate, leading to a small sample size; study population limited to colorectal surgeons in Australasia; and difficult to assess how restaging scans may change management plan.
