Objective: To evaluate the effect of an ERAS program on length-of-stay (LOS) among elective colorectal surgery patients at a safety-net hospital. Design: Retrospective chart review Setting: 500+ bed in a safety-net hospital. Patients and Methods: Retrospective review of elective colorectal surgery patients comparing those participating in an ERAS protocol to historical-control (HC) patients from the preceding year. Main Outcome Measures: The primary outcome was LOS. Secondary outcomes of interest included opioid utilization, fluid balance throughout the hospital stay, return of bowel function, 30-day complications emergency department visits, and readmissions. Sample Size: 193. Results: ERAS (n = 94) and HC groups (n = 99) were similar with regards to demographics and operations performed. ERAS patients had a longer operating room (OR) time (P = 0.010), however, OR fluid rates were lower for ERAS patients (P < 0.001) with more neutral fluid balance at discharge (closer to 0) (P = 0.006). ERAS patients received fewer opioids in the OR (P < 0.001) and throughout the hospital stay (P = 0.043). Median LOS was 4 days for both groups (P = 0.141) and no difference in 30-day emergency department (ED) visits, readmission, or complications. Conclusions: Benefits of ERAS may not be immediately evident post-implementation. Further study is needed regarding the maintenance of ERAS interventions over time and the impact on patient outcomes. Limitations: Single-center retrospective nature and surgeon turnover during this period.

We present a unique case of PMA, which began as a rectal abscess and progressed to PMA with a skip lesion present all the way up in the mid-rectal region. This is the first case in which PMA presented with skip lesions as opposed to a continuous lesion, and presented without fistulas and recurrent abscesses history but just a 4-day history of perianal burning, itching, and tingling. CT imaging, MRIs, and PET scans were done for the diagnosis of PMA. A discussion of the National Comprehensive Cancer Network (NCCN) guidelines on using radiation therapy followed by an abdominoperineal resection with inguinal node dissection for the management and treatment of PMA is reported.

Objective: Evaluate the role of local infiltration of the MB as an analgesic in the procedure for prolapse and hemorrhoids (PPH) surgery. Design: Prospective observational study. Setting: Tertiary health care center. Patients and Methods: Patients with grade-III hemorrhoids were included and were divided into two groups: A and B. Group A received a perianal injection of 2 mL of 1% MB with 10 mL of 25% bupivacaine. Group B received a perianal injection of 2 mL of normal saline with 10 mL of 25% bupivacaine. Main Outcome Measures: Patients were followed up prospectively for pain, hospital stay, and complications. Results were noted and compared between the two groups. Sample Size: 50 patients. Results: Group A had significantly lower pain scores on day 3 (mean ± SD 2.08 ± 1.08) and day 7 (mean ± SD 0.64 ± 0.95) as compared to the pain scores on day 3 (mean ± SD 3.92 ± 1.35) (P-value = 0.000) and day 7 (mean ± SD 2.40 ± 1.0) (P-value = 0.000) in group B.

Recent literature suggests this time-honored practice after uncomplicated diverticulitis is to be of little benefit, although uncertainty still persists regarding complicated diverticulitis. Objective: We analysed the rates of benign and malignant pathology identified on colonoscopy after conservatively managed uncomplicated and complicated diverticulitis in a hospital where such colonoscopies have been routine practice. Design: A retrospective cohort study was conducted. Setting: Gold Coast Hospital, Southport, Queensland, Australia. Patients and Methods: All patients who were admitted to the Gold Coast Hospital, Southport, Queensland, Australia, between June 2007 and June 2010 diagnosed with acute uncomplicated and complicated diverticulitis were included in the study. The patients were followed up and colonoscopy reports and histology results obtained. Main Outcome Measures: Benign and malignant pathology post uncomplicated and complicated diverticulitis. Sample Size: 144 patients were eligible for inclusion. Results: Between June 2007 and June 2010, 1073 patients were hospitalized with an admission diagnosis coding for diverticulitis. Of these, 144 patients had a computed tomography (CT) which confirmed the diagnosis of acute diverticulitis. Complete colonoscopy and histology data were obtained for 107 of these patients. Of these, 32 patients (29.91%) had pathology found at colonoscopy. One patient (0.9%) was found to have adenocarcinoma of the colon. Conclusion: Colonoscopy follow-up for acute diverticulitis has remained acceptable in many units to exclude alternate colonic pathology. However, recent literature has questioned the utility of this practice. This study – in keeping with this growing body of international literature – found the rate of synchronous/alternative pathology to be comparable to that of asymptomatic patient populations. Routine colonoscopies after uncomplicated colonic diverticulitis confidently diagnosed with a CT scan, therefore, cannot be justified. Limitations: Retrospective nature and sample size.

Although the prevalence of it is up to 30%, the common cause of perianal fistula is thought to be the crypto-glandular theory. Surgeons send perianal fistula specimens for histopathological analysis; however, it is unclear whether such practices should be performed routinely. Objective: Evaluating the utility of routine histopathology on perianal fistula specimens during surgery to exclude the diagnosis of Crohn's disease. Design: Multicenter retrospective study was conducted from January 2012 to October 2018 on patients who underwent surgery for perianal fistula and specimen sent for histology. Setting: Metropolitan tertiary referral center in Melbourne, Australia. Patients and Methods: 105 patients who underwent 124 anal fistula procedures and their perianal fistula specimens sent for histopathological analysis were selected from the medical database. Medical and pathology reports were analyzed and data were reviewed by a second author for consistency. Sample Size: 105 patients, 124 procedures. Main Outcome Measures: Histopathological results suspicious for Crohn's disease and endoscopic examination results to confirm Crohn's disease. Results: 41 together, 124 perianal fistula specimens were collected from 105 patients. The male to female ratio was 2.9:1 and the average age was 43.6 years. Nonspecific inflammation was seen in 121 (97.5%) specimens. Three specimens had granulomatous inflammation of which, only two (1.6%) had Crohn's disease confirmed on endoscopic biopsy of the terminal ileum. In 15 patients with Crohn's disease, none of the 19 specimens sent for histology demonstrated histopathological features of Crohn's disease. Conclusion: Routine histopathological analyses of perianal fistula specimens provide limited clinical value. Clinicians should selectively send specimens for histopathological analysis to limit the use of resources. Limitations: Retrospective study.

Direct sacral nerve stimulation is the most popular for neuro-modulation although it is technically demanding. Percutaneous and transcutaneous posterior tibial nerve stimulations are relatively newer approaches for neuro-modulation and they carry the advantage of being cheaper and less invasive. There is not much published data about the transcutaneous approach and in this study, we are describing our experience with this technique. Objective: This study was conducted to describe and determine the efficacy of percutaneous posterior tibial nerve stimulation in the treatment of fecal incontinence. Design: A prospective descriptive study. Setting: The colorectal clinic in the hospital was prepared with the required equipment. The authors funded all procedures performed and the patients paid no extra charges. Patients and Methods: Our study included 15 patients with fecal incontinence visiting the colorectal clinic in Ain Shams University Hospital. All patients received 12 sessions of electric stimulation, 3 sessions per week for 40 minutes each. Main Outcome Measures: Sample Size Wexner score and the short term effect of the treatment. Sample Size: 15 patients. Results: The study included 11 females and 4 males, 2 patients were excluded from the results. The results showed that there was improvement in mean Wexner score for these patients from 13 before the treatment to 8 after finishing the treatment course. Reassessment after 6 months of treatment revealed no deterioration in their continence.

Much debate remains though whether propofol can be safely administered by non-anesthesiologists. Objective: To compare the procedural outcome of patients undergoing colonoscopy with Propofol target-controlled infusion administered by anesthesiologists vs. non-anesthesiologists. Design: A retrospective review. Setting: A private community hospital in Dubai, United Arab Emirates. Patients and Methods: All consecutive patients (age > 13 years, with American Society of Anesthesiologists class I-II and no other contraindications to administration of sedation by non-anesthesiologists) who underwent colonoscopy between January 1, 2017 and September 30, 2017. In the initial part of the study, propofol was administered by an anesthesiologist until the endoscopists were trained to provide propofol anesthesia via targeted-controlled infusion [TCI] by syringe pump. Intraprocedural data was collected in a prospective registry. Statistical analysis was performed using Chi square and student t test. Main Outcome Measures: Cecal intubation rate, procedural time, procedural-related complications, and polypectomy/biopsy rate. Sample Size: 347 patients. Results: Group 1 [anesthesiologists] 84 patients, Group 2 [endoscopists] 263 patients. Mean age was 44.8 and 46.9 years in Group 1 and 2, respectively (P = 0.17). There was no difference in gender distribution. The mean procedural time was 21 minutes in both groups (P = 0.93).

Objective: We aim to assess the various modes of presentation, demographic profiles, and histopathological characteristics of tumors, and evaluate the efficacy of ASR over APR in terms of exposure, operating time, bleeding, etc., especially in the perineal/sacral part of the procedure. Design: This was a prospective observational study.Setting: This study was conducted at a superspeciality government hospital in eastern India. Patients and Methods: Patients diagnosed with low rectal carcinoma were included in the study. Two groups were formed using a stratified model of sampling theory; one group underwent APR while the other ASR. Main Outcome Measures: For patients with low rectal cancer, ASR is a feasible approach with reduced bleeding, lesser operating time in the perineal/sacral part of dissection, better exposure, and good oncological outcome.Sample Size: Thirty participants were included in the study. Results: Of the total study participants, 63% were males and 36% females. Patients in their 30s and 40s were the most commonly affected age group. Per-rectal bleeding was the most common presentation. The most common histological tumor encountered was well-differentiated adenocarcinoma. The mean operating time and mean blood loss with regards to the perineal/sacral part of the dissection was less in ASR than that in APR. In addition, the exposure was better in ASR.
