RESUMEN
PURPOSE: Fecal incontinence is a troublesome problem in the field of colorectal surgery. The main aim of this study was to adjust the anal canal resistance during operative management of anal incontinence using Endo-FLIP. METHODS: This was a prospective cohort study held at Cairo university hospital. Hundred forty-eight incontinent patients treated by different surgical procedures were included. During the procedure the Endo-FLIP was applied to adjust the anal canal dimensions (ACL and ACD) so the ACR could be adjusted based on the flow equation. These were also assessed pre-operatively with Endo-FLIP system and the flow equation calculator. The clinical severity of the disease and outcome after surgical procedures were assessed and correlated to the physiologic parameters. RESULTS: ACL, ACD and ACR had had significant correlations to the degree of incontinence (P < .001). ACL, ACD and ACR showed statistically significant change with primary repair and gluteus maximus transposition operations. After treatment of fecal incontinence, in good responders' group, the mean resting anal canal resistance increased significantly to 4649.05 ± 1161.49 (postoperative) while in poor responders' group it was 1919.9 ± 1077.73. CONCLUSIONS: The Endo-flip can be used to measure the anal canal geometric parameters (ACL and ACD) and then anal canal resistance could be calculated by the flow equation - pre-and post-operatively- which help the adjustment of the surgical repair of sphincter injury in fecal incontinence patients which may improve the surgical outcome.

PURPOSE: Gastrointestinal perforation is a significant injury that originates mainly from gastrointestinal ulcers. It is associated with a high rate of morbidity and mortality. The height of the column of the air under the diaphragm can be used to estimate the amount of peritoneal soiling due to viscus perforation. This study aimed to determine the correlation between this estimate and the incidence of morbidity and mortality. METHODS: To achieve this aim, a prospective cohort study was conducted on 83 patients at Kasr al ainy hospital who, between March 2021 and March 2022, presented to the emergency department with free air under the diaphragm at chest X-ray and required surgical intervention for a perforated viscus. For each case, the amount of peritoneal soiling and the amount of air under the diaphragm as determined by a chest X-ray were recorded. RESULTS: The mean air under the diaphragm in a plain erect chest X-ray was 1.78 ± 1.92 cm, and the mean amount of peritoneal soiling was 1201.83 ± 948.99 CC. There are positive correlations between the amount of air under the diaphragm as shown on an X-ray and the size of the perforation (p = 0.034), the amount of peritoneal soiling (p = 0.003), and the mortality (p = 0.013). CONCLUSION: There was a statistically significant correlation between air under the diaphragm according to X-ray and the amount of peritoneal soiling in patients with a perforated viscus. This measure can be used as a sensitive tool to predict morbidity and mortality as more free air in the chest X-ray is associated with significant mortality. These results may enhance the decision making using sensitive and available tool of diagnosis.

BACKGROUND: This study aimed to compare ventral mesh rectopexy (VMR) and pelvic organ prolapse suspension surgery (POPS) in management of patients presenting with rectal prolapse. METHODS: Our study was a prospective cohort trial in which 120 female patients with complete rectal prolapse were included, 60 patients had had VMR and the other 60 had had POPS as a surgical management for complete rectal prolapse. Results had been compared 6 months postoperatively regarding operative time, postoperative pain, hospital stay, complications of surgery including recurrence of the rectal prolapse, the efficacy of each operation in treatment of rectal prolapse and associated symptoms. RESULTS: The patients were assessed 6 months postoperatively. There was no significant statistical difference regarding hospital stay and postoperative pain. Operative time was significantly shorter in POPS in comparison with VMR (P value < 0.05). VMR showed slight improvement regarding constipation and continence scores; however, this was statistically significant. VMR showed less complications compared to POPS. Complications with rectopexy happened only with 4 patients compared to 24 patients in POPS groups, 2 cases of recurrence in rectopexy group compared to 6 cases of recurrence in POPS. CONCLUSION: POPS is comparable to VMR in management of rectal prolapse and in improving the ODS symptoms. Thus, POPS can be used as easier, faster option to treat rectal prolapse in selected patients.

Perianal sepsis and fistula is a troublesome disease in the field of colorectal surgery in term of recurrence and fecal incontinence. The aim of our study is to evaluate the role of 'one stage complex anal fistula excision with reconstruction of anal sphincter without stool diversion' regarding fecal incontinence and recurrence. This was prospective cohort study on 175 patients of complex high peri-anal fistulae, the patients were subjected to fistulectomy and reconstruction (primary suture repair) of anal sphincter without stool diversion, the patients were followed up 1 year postoperatively after complete healing of the wound regarding their continence to stool and gases using Wexner score and recurrence of the fistula which is examined clinically and radio-logically using MRI. Among the 175 patients only four had developed fecal incontinence with varying degrees in which 2 patients developed gas incontinence and 2 patients developed soiling, after 3 months 8 patients had recurrence and after 6-9 months 6 patients developed recurrence . Also at the end of follow up period upon performing the confirmatory MRI, 2 patients showed hidden fistulous tracts ending into a high abscess cavity. This ends up into total of 16 recurrent cases. Five patients experienced delayed wound healing. In conclusion, Compared to other treatment modalities for complex anal fistula found in literature, it had been found that one stage surgery (fistulectomy with primary sphincter repair) has good results regarding healing of the fistula with low risk of incontinence, low recurrence rate and good wound healing.

PURPOSE: Restorative surgery for rectal cancer is usually criticized by its functional outcomes. The aim of this study is to assess the efficacy "taeniectomy" pouch in comparison with transverse coloplasty pouch. STUDY DESIGN: This was a prospective controlled study. Most patients who were candidate for low rectal resection presented to colorectal unit at Cairo university hospitals during the period from February 2013 to August 2016 were divided into two groups. The total number of patients enrolled in the study was 180 patients. Ninety patients were subjected to low rectal resection with the transverse coloplasty pouch, and 90 patients were subjected to low rectal resection with the newly described taeniectomy pouch. Safety and feasibility of both techniques were assessed about leakage, operative time, difficulty in evacuation, incontinence, number of daily motions and postoperative urgency. Both groups were assessed clinically, by means of defecography and anorectal manometry. RESULTS: There was no significant statistical difference between taeniectomy and transverse coloplasty regarding postoperative leakage (P value = 0.988), postoperative mortality (P value = 0.99) and functional outcomes including number of motions per day (P value was 0.403 at 3 months and 0.361 at 12 months), urgency (P value was 0.688), continence grade (P value was 0.320 and 0.683 in 3 and 12 months, respectively) and manometric findings. However, taeniectomy is statistically significant better in terms of operative time (P value = 0.001). CONCLUSIONS: Taeniectomy is a newly described, technically easier technique for pouch formation after low rectal resection that can be used as a safe and effective alternative for the widely used transverse coloplasty.

AIM: TNM staging and histological grading of rectal cancer has undergone no or minimal changes during the past 20 years despite their major impact on planning, reporting and outcome of the disease. The addition of category 'F' to the 'TNM' staging of colorectal cancer, which becomes TNMF will accommodate the expanding list of risk factors that may affect the management and thus avoid squeezing them into the TNM categories. METHODS: Reporting of the following risk factors was traced in 730 (664 retrospective and 66 prospective) cases of colorectal cancer: age, Tumor location, preoperative CEA, intraoperative tumor perforation and blood transfusion, quality of TME, tumor grade, non nodal T.Ds, Lymphovascular invasion, lymph node ratio, circumferential tumor margins, apical lymph nodes, infiltrating or pushing and K-ras gene mutation. RESULTS: The reporting of most risk factors was inadequate; also there is marked improvement in reporting in the prospective cases in preoperative CEA, intra operative blood transfusion and tumor perforation, quality of TME, tumor grade and non-nodal T.Ds (P-value <0.0001). CONCLUSION: The addition of category 'F' to the TNM staging system to become TNMF may avoid ignoring already established risk factors due to our inability to accommodate them in the inhospitable TNM categories.

BACKGROUND: Purpose was to compare the oncologic outcome of neoadjuvant chemoradiotherapy (nCXRT) versus postoperative chemoradiotherapy (pCXRT) for locally advanced mucinous rectal carcinoma (MRC) having curative total mesorectal excision (TME). METHODS: One hundred and two patients with MRC (T3-4 and/or N1-2) of middle and lower third rectum were included. Patients were non-randomly divided into 2 groups: Group A (N = 61) had nCXRT followed by total mesorectal excision (TME) after 8-11 weeks and Group B (N = 41) had TME followed by pCXRT. Primary end points were disease free survival (DFS) and overall survival (OS). Secondary endpoints were tumor regression grade (TRG) and morbidity. RESULTS: In group A, 29 patients had partial response after nCXRT, 26 patients showed no change and 6 patients had progression. TME was done in 55 patients in group A and 41 patients in group B. Six patients in group A turned to be unresectable after nCXRT due to progressive disease. Mean follow-up was 53 months. In patients received TME, Four-year DFS was higher in group A compared to group B yet not statistically significant (DFS 0.69 [95% CI 0.54-0.85] vs. 0.67 [95% CI 0.47-0.87]; P = 0.39). However, actuarial 4 years OS was comparable in both groups (0.72 [95% CI 0.59-0.91] vs. 0.70 [95% CI 0.55-0.88]; P = 0.46 in groups A and B respectively). Multivariate analysis revealed that age <40, and N2 were risk factors of recurrence. CONCLUSION: Whilst accepting that the numbers are small, there was no statistical difference in outcome (DFS and OS) between patients receiving pre- or post-operative chemo-radiotherapy. In most MRC patients, tumor regression is not significant after nCXRT and there is considerable possibility of tumor progression during nCXRT treatment. So, nCXRT should be used with close follow-up in MRC for early detection of possible tumor progression. If the patient cannot tolerate nCXRT, it is possibly safe to do surgery followed by pCXRT. Prospective study is needed to study the value of nCXRT in MRC.

BACKGROUND AND STUDY AIMS: Complete surgical removal of the involved bowel segment in colorectal cancer is the most effective primary treatment. The main prognostic factors for colorectal cancer are penetration of the tumour into different layers of the bowel wall and regional lymph node involvement. Positive lavage cytology has been used to predict peritoneal recurrence, but its effectiveness remains controversial. This study was conducted to assess the prevalence of positive peritoneal lavage cytology in correlation with the tumour stage in patients with colorectal cancer. PATIENTS AND METHODS: This prospective cross-sectional study was performed on 20 patients with different cases of colorectal cancer attending the colorectal unit and emergency department of the Kasr Al Ainy Hospital, Cairo University Hospitals, from March 2012 to March 2013. RESULTS: The patients' gender did not influence the peritoneal lavage cytology results (p = 0.062); there is no significant correlation between the TNM staging system and cytology in patients with colorectal cancer (p = 0.253). CONCLUSION: Although there is a positive linear correlation between the tumour stage and positive peritoneal lavage cytology, it did not reach a statistically significant level. In addition, the greater the depth of invasion, the higher the lavage cytology rate. However, this trend was not statistically significant.
