Determinants of survival and recurrence in patients with stage I colorectal cancer.

Background: Due to the novel advanced screening methods, the number of patients diagnosed with stage I colorectal cancer (CRC) is increasing. This retrospective cohort study aimed to identify recurrence and survival risk factors of patients with stage I CRC after surgery. Materials and methods: Patients with stage I CRC were evaluated, and their demographic and clinicopathologic variables were recorded. The log-rank test assessed the association of variables with overall survival (OS), recurrence-free survival (RFS), local recurrence, and distant metastasis. Results: The median overall survival period was 51 months. The recurrence rate was 13.7%: 7.2% local and 9.3% distant recurrence. One-, two-, three-, and five-year RFS were 92%, 89%, 87%, and 83%, respectively, and OS were 96%, 93%, 90%, and 89%, respectively. Local and distant recurrence rates were higher in patients with higher tumor grades. Additionally, RFS and OS were worse in patients with higher tumor grades, and perforation was associated with worse OS. Conclusions: The determinants of survival and recurrence identified in the present study can be used to improve patient outcomes by early diagnosis and appropriate management of high-risk patients.

Eight years experience of transanal endoscopic microsurgery

Introduction: Transanal Endoscopic Microsurgery (TEM) is a minimally invasive method for management of different proctologic conditions. Despite widespread use of this method, it is not used widely in Iran. This report is about to describe the application of TEM in managing different proctologic conditions in a tertiary colorectal referral center in Iran regarding methods and complications. Methods: All of the patients' documents such as procedure, method, early postop complications and further operations were actively reviewed and the data were entered in to the database. Results: Since 2012 till the end of 2020 chart review was done and 150 cases of TEM operation were found. The most frequent procedure that was done was resection procedure. Using different energy devices during surgery or suturing versus not suturing the defect were not associated with complication. There was a case of in hospital mortality and one case delayed perianal fistula following TEM. Measurement of lesion distance from anal verge was not significantly different using TEM or colonoscopy. Villous adenomas detected in colonoscopy were mostly associated with malignancy. In evaluated resected lesions most of cases had free base and distance from anal verge or using different energy devices were not associated with obtaining free base. Conclusion: TEM is a safe minimal invasive procedure with acceptable complications that could be helped in managing different proctologic conditions and the results of reviewing our patients revealed the same results that is reported from other colorectal centers.

Effects of neuromodulation on treatment of recurrent anal fissure: A systematic review.

BACKGROUND: Anal fissure is a linear tear in the distal anoderm most frequently occurring in the posterior midline. Lateral internal sphincterotomy is considered the gold standard for the treatment of this condition. To this date, several pharmacological and neuromodulatory therapies have been tried out as alternative non-invasive treatments for anal fissures, however, the efficacy of some of these methods remains to be understood. OBJECTIVE: the primary aim of this study was to review available literature on neuromodulatory treatments for recurrent anal fissure as a potentially effective cure for this condition. DATA SOURCES: A search was conducted among five main online databases Embase, PubMed, Web of Science, Scopus, and Scholar. STUDY SELECTION: All published human studies in English literature addressing neuromodulation for the treatment of recurrent anal fissure were selected. INTERVENTION: neuromodulation for the treatment of anal fissure. We chose to include all articles in which the authors stated that the procedure they performed was via neuromodulation technique, or that the described technique used in their study resembled the technique. RESULT: Among a total of 3487 evaluated studies, seven represented the effects of neuro modulation on treatment of recurrent anal fissure, among which two were randomized controlled trials and the rest were prospective studies. A total of 186 patient were evaluated in these studies. The mean age of the participants was 46.97 ± 8.2. The average VAS score before intervention was 7.77 ± 2.13, which decreased to 0.31 ± 1.13 after intervention. LIMITATIONS: limitations of this study include the lack of related articles, and data regarding this subject. CONCLUSION: Posterior tibial nerve stimulation (PTNS) provides rapid pain relief and fissure healing especially in short-to mid-terms with little to no complications, however, using this treatment, symptoms of anal fissure do not improve as well as LIS, especially in the long-term.

Heart Rate Variability May Predict the Severity of Appendicitis: A Cross-Sectional Study.

Objective: To evaluate the role of heart rate variability (HRV) in predicting pre-operative severity of appendicitis. Methods: In this cross-sectional study, 171 cases of acute appendicitis who underwent appendectomy were enrolled. Pre-anesthetic pulse rate of included patients were documented while the severity of appendicitis was determined by intra-operative evidences reported by two independent surgeons. Demographic characteristics, laboratory variables, and Alvarado criteria were recorded. Results: The mean age of patients was 28.75±4.21 years; 54% were men. HRV negatively associated the severity of appendix inflammation. A positive association was found between HRV and omental wrapping and Alvarado score (p<0.01). The receiver operating characteristic (ROC) curve analysis demonstrated that HRV could differentiate simple and complicated appendicitis with a sensitivity of 78.5% and specificity of 97.2%. Conclusion: The present findings revealed that HRV may predict the pre-operative severity of appendicitis and help differentiate simple and complicated appendicitis.

Report of 13-year survival of patients with colon and rectal cancers; lessons from Shiraz colorectal cancer surgery registry system of a level three medical center.

BACKGROUND: Colorectal cancer (CRC) is the second most common cancer in women and the third most common cancer in men worldwide, with an increasing trend in its incidence in Asian countries. In the present study, we aimed to describe the 13-year results of patients with CRC based on the Shiraz Colorectal Cancer Surgery (SCORCS) registry system in patients with a pathologically confirmed diagnosis of colon cancer (CC) and rectal cancer (RC) undergoing surgery. METHODS: Between 2007 and 2020, 811 patients, including 280 patients with CC and 531 patients with RC, registered in SCORCS, were included in the present study. The information collected for this study included demographic characteristics of the patients, primary clinical presentations, laboratory findings before surgery, radiologic and colonoscopy results, and surgical procedures. Death was confirmed by the physician as "CRC-related". The data were analyzed by SPSS software version 21; life table and Kaplan-Meier curve were used for evaluating the overall survival, recurrence, and metastasis rates and Log-Rank test or Breslow test to check significant differences between the subgroups. The Cox proportional regression model was fitted to evaluate the prognostic factors of survival recurrence and metastasis. RESULTS: Laparoscopy was performed in 60% of patients (66% in RC and 51% in CC), laparotomy in 32% (27% in RC and 41% in CC), and 7% required conversion. The median time of follow-up was 29 months in all patients; 28 months in patients with RC, and 33 months in patients with CC; 1, 3, and 5 years' survival rate was 90, 70, and 63% for all the patients, 89%, 67%, and 58% for RC and 90%, 74%, and 71% for CC, respectively (P = 0.009). The Cox regression analysis revealed tumor stages II, (P = 0.003, HR:2.45, 95% CI;1.34-4.49), III, (P ≤ 0.001, HR:3.46, 95% CI;1.88-6.36) and IV, (P ≤ 0.001, HR:6.28, 95% CI;2.73-14.42) in RC and stage IV, (P = 0.03, HR:9.33, 95% CI;1.1-76.37) in CC were the significant survival prognostic factors. The metastasis and recurrence of the tumors occurred earlier in patients with RC than CC (P = 0.001 and 0.03, respectively). CONCLUSIONS: Long-term follow-up of patients with CRC in an Iranian population indicated the significance of screening for diagnosis of early stages and improved survival of the patients.

Prognostic Factors of Rectal Cancer in Southern Iran.

BACKGROUND: Rectal cancer accounts for one-third of all colorectal cancer (CRC) cases. Due to physiological and anatomical differences, some researchers consider rectal cancer as a separate organ malignancy during the recent decades. However, limited studies have been conducted in this regard in Iran. Therefore, the aim of this study is to determine survival of rectal cancer and its, affecting factors in Fars province, southern Iran. METHODS: In this cohort study, we used the data of 387 patients with rectal cancer gathered by the Colorectal Research Center of Shiraz University of Medical Sciences between 2007 and 2015. The impact of 35 explanatory factors including demographic information, medical history, pathologic data, and imaging findings was evaluated using Cox regression analysis. RESULTS: Out of all patients, 111 ones (29%) died. The median follow-up period was 36 months. The patients' mean age at diagnosis was 56.72 ± 13.89 years. Their 5-year survival was 65% (95% CI: 58-69%). The results of multiple Cox regression analysis showed that sex (male/female; HR = 1.73, 95% CI: 1.15-2.67), vascular invasion (yes/no; HR = 2.40, 95% CI: 1.45-3.99), and lymph node ratio (> 0.2 vs ≤ 0.2; HR = 2.19, 95% CI: 1.41-3.40) were significantly correlated to survival. CONCLUSION: Various geographical parts of Iran show different rates regarding rectal cancer survival. A better 5-year survival rate was detected by this study for the patients with rectal cancer in Fars province, southern Iran, compared to many parts of the country. Moreover, gender, vascular invasion, and nodal status played an important role in survival of rectal cancer.

Prognostic Factors of Recurrence and Survival in Operated Patients with Colorectal Cancer.

BACKGROUND: The recurrence of colorectal cancers is considered to be one of the greatest post-surgical complications that is affected by various factors. This study was designed to investigate the prognostic factors that affect the recurrence and survival of patients with colon and rectal cancers. METHODS: A retrospective study was performed on 380 patients with colorectal cancers who underwent surgery were enrolled in the study (152 patients with colon cancer and 228 patients with rectal cancer). Preoperative serum albumin level, type of surgery, tumor size, differentiation grade, proximal, distal and radial, and marginal involvement, the total number of excised lymph nodes, the number of involved lymph nodes, and tumor stage were recorded. Also, the incidences of recurrence and metastasis were recorded during the study. RESULTS: 380 patients with a mean age of 57.11 years were enrolled in the study. 152 patients with an average age of 57.57 years were diagnosed as having colon cancer. Recurrence and metastasis occurred in two patients (1.3%) and five patients (3.3%), respectively. 18 patients (11.8%) died because of colon cancer. 228 patients with a mean age of 56.81 had rectal cancer. Recurrence was seen in 19 patients (8.3%) and metastasis in 33 patients (14.5%). 38 patients (16.7%) died because of rectal cancer. Tumor size and involved lymph nodes were independent prognostic factors for the recurrence and metastases of colon cancer. Only involved lymph nodes were associated with death due to colon cancer. Independent prognostic factors for rectal cancer metastasis include serum albumin level and age. The total number of excised lymph nodes was the only predictor of tumor recurrence and death in rectal cancer. The median survival times of colon and rectal cancers were 90 and 110 months, respectively. CONCLUSION: The size of the tumor and the number of involved lymph nodes were independent prognostic factors for recurrence and metastasis of colon cancer. Also, the number of involved lymph nodes was associated with colon cancer-related deaths. In the case of rectal cancer, serum albumin levels and age predicted metastases. Only the total number of excised lymph nodes had a reverse relationship with recurrence and rectal cancer-related death.

Two cases of primary leiomyosarcoma of sigmoid colon treated with laparoscopic surgery: A case report and a review of literature.

INTRODUCTION AND IMPORTANCE: Leiomyosarcoma (LMS) of the colon is an extremely rare and highly invasive tumor arising from the muscularis propria of the gastrointestinal tract. After the introduction of oncogenic role of KIT by immunohistochemistry (IHC), the reported cases of gastrointestinal leiomyosarcoma were highly limited. True LMS of the colon is such a rare disorder that there isn't much description of its nature. CASE PRESENTATION: We reported two very rare cases of primary leiomyosarcoma of sigmoid colon, which referred to our institution with symptoms of abdominal pain, lower GI bleeding and fatigue. After the initial investigations, both patients were diagnosed with primary LMS of sigmoid colon that underwent laparoscopic tumor resection. CLINICAL DISCUSSION: The classical colonic LMS presents with a vast majority of non-specific symptoms including mild abdominal pain, fresh/obscure rectal bleeding, and weight loss. The most common location for colonic LMS is the sigmoid colon, and ascending colon. The prognostic factors for the disease outcome have not been established properly; however, patient age, tumor size/grade, and local/distant dissemination are of great importance. CONCLUSION: Herein, we reported two rare cases of primary leiomyosarcoma of sigmoid colon that was treated with laparoscopic surgery.

How Does Fat Mass Change in the First Year After Bariatric Surgery? A Systemic Review and Meta-Analysis.

This systematic review and meta-analysis investigated the time-course effect of different type of bariatric surgeries (BS) up to 1 year post-surgery on fat mass (FM) and body fat percentage (BFP) in patients with morbid obesity. We searched PubMed, Scopus, EMBASE, ISI web of science, and Cochrane databases from October 2002 until May 2020 with no restriction in the English language, to find studies examining the effect of BS on FM (kg) and BFP (%) in morbid obese patients. Meta-analysis of 103 studies carried out on data of 18,166 and 14,575 morbid obese patients following BS, showed that BS was associated with a substantial decrease in FM and BFP, respectively, in 1 month (- 8.17 kg [95% CI - 9.07, - 7.27] and - 1.51% [95% CI - 2.56, - 0.46]), 3 months (- 15.75 [95% CI - 17.49, - 14.0] and - 4.90 [95% CI - 5.97, - 3.83]), 6 months (- 22.51 [95% CI - 23.93, - 21.09] and - 8.56% [95% CI - 9.63, - 7.49]), and 12 months (- 29.69 [95% CI - 31.3, - 28.09] and - 13.49% [95% CI - 14.52, - 12.40]) after the surgery. In conclusion, BS was associated with sustained declines in FM and BFP, from 1 to 12 months, with no indication of plateau phase post-surgery post-operatively. The present study emphasizes that post-bariatric care should have more focus on FM loss during 1-year post-surgery to identify the patients at risk for fat loss plateau.

Outcome of Fecal Incontinence in Patients with Rectal Prolapse Undergoing the Altemeier Procedure with or without Posterior Levatorplasty / Desfecho de incontinência fecal em pacientes com prolapso retal submetidos ao procedimento de Altermeier com ou sem levatorplastia posterior

Abstract Objective To compare the fecal incontinence status of patients submitted to theAltemeier procedure with or without posterior levatorplasty. Materials and Methods Medical records of the patients who underwent the Altemeier procedure at Shahid Faghihi Hospital (in Shiraz, Iran) from 2014 to 2018 were retrospectively studied. Patients older than 17 years of age who underwent the Altemeier procedure due to complete rectal prolapse were considered. In some cases, the operation was performed with posterior levatorplasty. Rectal prolapse due to collagen or connective tissue disorders, anal/sacral anomalies, immunodeficiency, history of rectal surgery, and pelvic radiotherapy were the exclusion criteria of the present study. In addition to the demographics (including age, gender, and body mass index), the fecal incontinence status of each case was determined through theWexner scale preoperatively and 12 months after the surgery. The incontinence scores were then compared against the baseline values of the two groups of patients: those with and those without posterior levatorplasty. The statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS, IBM Corp., Armonk, NY, US), software, version 21. Results In total, 53 patients (17 men and 36 women) with a mean age of 55.23 ± 18.24 years were analyzed. The comparison of the pre- and postoperative scores on theWexner scale between the two groups revealed no statistically significant difference (p >0.05). Conclusion Posterior levatorplasty during the Altemeier procedure did not result in significant improvement of the fecal incontinence outcome of the patients.

Resumo Objetivo Comparar o status de incontinência fecal de pacientes após o procedimento de Altemeier com e sem levatorplastia posterior. Materiais e métodos Os prontuários médicos dos pacientes submetidos ao procedimento de Altemeier no Shahid Faghihi Hospital (em Shiraz, Irã) entre 2014 e 2018 foram avaliados retrospectivamente. Pacientes com idade superior a 17 anos submetidos ao procedimento de Altemeier devido a prolapso retal completo foram considerados. Em alguns casos, a operação foi realizada com levatorplastia posterior. Prolapso retal devido a distúrbios de colágeno ou do tecido conjuntivo, anomalias anais/sacrais, imunodeficiência, histórico de cirurgia retal, e radioterapia pélvica foram os critérios de exclusão deste estudo. Além dos dados demográficos (incluindo idade, sexo, e índice de massa corporal), o status da incontinência fecal de cada caso foi determinado por meio da escala de Wexner antes e doze meses após a cirurgia. Então, as pontuações de incontinência foram comparadas aos valores de referência dos dois grupos de pacientes: com e sem levatorplastia posterior. A análise estatística foi feita usandose o programa Statistical Package for the Social Sciences (SPSS, IBM Corp., Armonk, NY, EUA), versão 21. Resultados No total, 53 pacientes (17 homens e 36 mulheres) com idade média de 55.23 ± 18.24 anos foramavaliados. A comparação entre os grupos das pontuações na escala de Werner no pré e pós-operatório não revelou diferença estatisticamente significativa (p>0.05). Conclusão Levatorplastia superior durante o procedimento de Altemeier não resultou em melhora significativa do desfecho da incontinência fecal dos pacientes.

Efficacy and safety of sequential neoadjuvant chemotherapy and short-course radiation therapy followed by delayed surgery in locally advanced rectal cancer: a single-arm phase II clinical trial with subgroup analysis between the older and young patients.

PURPOSE: This study was performed to investigate the efficacy and safety of short-course radiation therapy (SCRT) and sequential chemotherapy followed by delayed surgery in locally advancer rectal cancer with subgroup analysis between the older and young patients. MATERIALS AND METHODS: In this single-arm phase II clinical trial, eligible patients with locally advanced rectal cancer (T3-4 and/or N1-2) were enrolled. All the patients received a median three sequential cycles of neoadjuvant CAPEOX (capecitabine + oxaliplatin) chemotherapy. A total dose of 25 Gy in five fractions during 1 week was prescribed to the gross tumor and regional lymph nodes. Surgery was performed about 8 weeks following radiotherapy. Pathologic complete response rate (pCR) and grade 3-4 toxicity were compared between older patients (≥65 years) and younger patients (<65 years). RESULTS: Ninety-six patients with locally advanced rectal cancer were enrolled. There were 32 older patients and 64 younger patients. Overall pCR was 20.8% for all the patients. Older patients achieved similar pCR rate (18.7% vs. 21.8; p = 0.795) compared to younger patients. There was no statistically significance in terms of the tumor and the node downstaging or treatment-related toxicity between older patients and younger ones; however, the rate of sphincter-saving surgery was significantly more frequent in younger patients (73% vs. 53%; p=0.047) compared to older ones. All treatment-related toxicities were manageable and tolerable among older patients. CONCLUSION: Neoadjuvant SCRT and sequential chemotherapy followed by delayed surgery was safe and effective in older patients compared to young patients with locally advanced rectal cancer.

Parastomal Hernia Following Abdominoperineal Resection / Hérnia paraestomal após ressecc¸ão abdominoperineal

ABSTRACT Parastomal Hernia (PSH) is a common complication of patient who undergone ostomy especially end colostomy. Presence of hernia defect is associated with the risk of strangulation and obstruction so understanding the potential risk factor such as patient's factor and technical issues is important. This study is evaluating the incidence of PSH hernia in patients who undergone end colostomy due to Abdominoperineal Resection (APR) in a tertiary colorectal surgery referral center and explore the possible risk factors of this complication. The study was designed as a retrospective cross sectional study on 41 patients who undergone end colostomy due to APR. Three patient lost the follow up and 13 patients died and 25 patients were enrolled in study. Demographic data, history of smoking, steroid administration, Diabetes, obstructive pulmonary disease, transfusion, Neoadjuvant therapy, wound infection and Body mass Index (BMI) were gathered. The mean age of participants was 58.8 and the mean BMI was 25.04 kg/m2. The incidence of PSH was 40% and 68% of operations were done with Laparoscopy. This study could not find statistically significant risk factor for PSH. The 40% incidence of PSH is noticeable and specific strategies should be applied to reduce such complications. Larger studies is essential to investigate the possible etiologies of this complication.

RESUMO A hérnia paraestomal é uma complicação comum em pacientes submetidos a estomia, especialmente a colostomia terminal. A presença de defeito de hérnia está associada ao risco de estrangulamento e obstrução, portanto, é importante compreender o potencial fator de risco, como o fator do paciente e questões técnicas. Este estudo avalia a incidência de hérnia paraestomal em pacientes submetidos à colostomia terminal devido à ressecção abdominoperineal em um centro terciário de referência em cirurgia colorretal e explorar os possíveis fatores de risco dessa complicação. O desenho do estudo foi transversal retrospectivo de 41 pacientes submetidos à colostomia terminal devido à ressecção abdominoperineal. Três pacientes foram perdidos no seguimento, 13 pacientes morreram, e 25 pacientes foram incluídos no estudo. Dados demográficos, história de tabagismo, administração de esteroides, diabetes, doença pulmonar obstrutiva, transfusão, terapia neoadjuvante, infecção de ferida operatória e Índice de Massa Corporal foram coletados. A média de idade dos participantes foi 58,8 e o índice de massa corporal médio foi 25,04 kg/m2. A incidência de hérnia paraestomal foi de 40% e 68% das cirurgias foram realizadas por laparoscopia. Este estudo não encontrou fator de risco estatisticamente significativo para hérnia paraestomal. A incidência de 40% de hérnia paraestomal é perceptível e estratégias específicas devem ser aplicadas para reduzir tais complicações. Estudos maiores são essenciais para investigar as possíveis etiologias dessa complicação.

Prognostic Factors Affecting Short- and Long-Term Recurrence-Free Survival of Patients with Rectal Cancer using Cure Models: A Cohort Study.

BACKGROUND: Understanding the prognostic factors affecting the recurrence-free survival (RFS) of patients with rectal cancer (RC) is the mainstay of care. The present study aimed to identify factors affecting both short- and long-term RFS of patients with RC using semiparametric mixture cure models. METHODS: The data were obtained from the database of the Colorectal Research Center of Shiraz University of Medical Sciences, Shiraz, Iran, which was collected during 2007-2017. To determine the factors affecting recurrence, cure models were applied to short-term and long-term RFS of patients with RC separately. The cure rate was calculated using the smcure package in R 3.5.1 (2018-07-02) software. P<0.05 was considered statistically significant. RESULTS: Out of the 376 eligible patients with RC, 75.8% of men and 74.5% of women were long-term survivors. The mean age of the patients was 57.0±13.8 years. Lymph node ratio (LNR)≤0.2 increased the probability of short-term RFS. The prominent factors affecting long-term RFS were body mass index (BMI)<25 kg/m2 (OR=1.98, P=0.047), tumor-node-metastasis (TNM) stage (OR=6.48, P<0.001), abdominal pain (OR=2.15, P=0.007), and computed tomography (CT) scan detected pelvic lymph nodes (OR=3.40, P=0.01). Over a 9-year follow-up period, the empirical and estimated values of cure rates were 75.3% and 83.9%, respectively. CONCLUSION: The results showed that factors affecting short-term RFS might be different from long-term RFS. A lower BMI was related to a poorer prognosis in patients with RC. Early diagnosis leads to a lower TNM stage and could increase the probability of long-term RFS.

A novelty in laparoscopic total colectomy with natural orifice specimen extraction using a plastic cover / Uma novidade na colectomia total laparoscópica com extração de espécime em orifício natural usando uma cobertura plastic

Abstract Introduction: Minimally invasive colectomy has been performed for some years for many patients worldwide without much complications compared to the open approach. In this study we explained our experience regarding a modification in laparoscopic total colectomy and removing the specimen with Natural Orifice Specimen Extraction (NOSE) through rectum using a plastic cover for the first time. Methods and material: This was an experimental study on a new technique of total colectomy with a small modification. Total colectomy was performed based on 7 port laparoscopic approach. Rectum was sparred. Colon was then taken out through the anal canal using a plastic cover. Results: Thirteen patients underwent laparoscopic total colectomy by removal of the specimen through rectum. Mean age of patients was 42.23 ± 8.15 years. Mean duration of operation was 130 ± 32.4 min. All patients had an uneventful postoperative hospitalization. Discussion: Laparoscopic total colectomy has been proven to have superior benefits than the open approach. In NOSE technique, colon is removed from the anal canal without any complication or consuming much time. This technique might have less pain and removes the complications associated with an incision on the skin to remove the specimen. Also, due to low price of a usual plastic cover, it can be used instead of other techniques to remove the specimen through the rectum.

Resumo Introdução: A colectomia minimamente invasiva vem sendo realizada há alguns anos em muitos pacientes no mundo inteiro, apresentando menos intercorrências do que a abordagem aberta. Neste estudo, os autores relatam sua experiência com uma modificação da colectomia total laparoscópica e extração de espécime em orifício natural (NOSE) pelo reto, usando uma cobertura plástica pela primeira vez. Métodos e materiais: Este foi um estudo experimental sobre uma nova técnica de colectomia total com uma pequena modificação. A colectomia total foi realizada com base na abordagem laparoscópica de sete portas. O reto foi poupado. O cólon foi então retirado pelo canal anal usando uma cobertura plástica. Resultados: Treze pacientes foram submetidos a colectomia total laparoscópica por remoção do espécime pelo reto. A idade média dos pacientes foi de 42,23 ± 8,15 anos. A duração média da operação foi de 130 ± 32,4 minutos. Para todos os pacientes, a internação pós-operatória transcorreu sem intercorrências. Discussão: Foi comprovado que a colectomia total laparoscópica apresenta benefícios superiores à abordagem aberta. Na técnica NOSE, o cólon é removido mais rapidamente do canal anal, sem nenhuma intercorrência. Essa técnica pode causar menos dor e remove as complicações associadas a uma incisão na pele para remover o espécime. Além disso, devido ao baixo preço de uma cobertura plástica comum, ela pode ser usada no lugar de outras técnicas para remover o espécime pelo reto.

Optimizing compliance with surgical antimicrobial prophylaxis guidelines in patients undergoing gastrointestinal surgery at a referral teaching hospital in southern Iran: clinical and economic impact.

BACKGROUND: Antibiotic prophylaxis is one of the major approaches to prevent surgical site infection. Despite the availability of international guidelines on it, the practice of antibiotic prophylaxis is still far from optimal. This study aimed to assess the impact of guideline implementation on the rational use of prophylactic antibiotics and its cost-saving effect in gastrointestinal surgery by clinical pharmacist intervention. METHODS: A pre and post intervention study was carried out between October 2017 and June 2018 on patients who underwent gastrointestinal surgery in a major referral teaching hospital in Shiraz, southern Iran. The intervention phase consisted of revising the institutional guidelines for surgical antimicrobial prophylaxis, assigning a clinical pharmacist to the surgical department, and arranging several meetings with the surgical department regarding the appropriate utilization of antibiotics. Differences in antibiotic utilization in patients before and after the intervention phase were compared. Exposures were surgical antimicrobial prophylaxis timing and agents, and main outcomes were incidence of surgical site infection and length of hospital stay. RESULTS: A total of 430 patients were included in the post intervention phase, while 445 patients were included in the baseline evaluation. Promoting appropriate antibiotic use in the post intervention group had the potential to decrease medication costs by reducing unnecessary prescriptions and duration of antibiotic usage (P<0.001). In the pre intervention group, the mean cost of antibiotic prescriptions was 11.5 times that of the post intervention group. Mean hospitalization in the pre intervention group was greater than the post intervention group (P<0.001). Furthermore, our data revealed that the rate of postsurgery infection in the post intervention group was 3.03%, while this rate was 6.76% in the preintervention group (P=0.01). CONCLUSION: This study provides evidence that adherence to surgical antimicrobial prophylaxis guidelines increased the rational use of prophylactic antibiotics, with substantial cost savings in patients who underwent surgery.

Outcomes of Implementation of Sacral Nerve Stimulation in Incontinent Patients in Shiraz.

BACKGROUND: Fecal incontinence is a common disorder in old age; however, it may not threaten life, but it can cause morbidity and many problems. Sacral nerve stimulation (SNS) is a minimally invasive surgical procedure performed by chronic electrical stimulation of the nerves in the sacral plexus through a lead implanted at the S3 foramen. This study aimed to evaluate the outcomes of SNS in Shiraz. MATERIALS AND METHODS: Data from patients who underwent implantation of an SNS device from 2012 to 2018 were reviewed in Shiraz. Thirty patients who had incontinence were evaluated by a committee. Pre- and postoperative assessments of the severity of incontinence were performed using Wexner Incontinence Score. Statistical analysis was performed using paired t-test. RESULTS: Twenty-seven patients proceeded to insertion in the temporary SNS, and of these, 16 were elected to have a permanent SNS. Finally, seven patients were satisfied with their treatment. There was a significant reduction in the pre- and post-SNS Wexner Incontinence Scores from a median of 15-10, respectively (P < 0.05). CONCLUSION: In our study, 16 patients underwent SNS protocol, and 43.7% of them showed a good response and recovered. It is recommended as a method for the treatment of fecal incontinence. Permanent SNS is effective, showing a significant improvement in fecal incontinence scores.

Effects of Stapled Hemorrhoidopexy on Anorectal Function: A Prospective Randomized Controlled Trial.

BACKGROUND: Stapled hemorrhoidopexy is a safe and acceptable alternative to traditional hemorrhoidectomy with shorter hospital stay, better satisfaction, and less postoperative pain. There have, however, been reports on early and late complications. Therefore, the present study was designed to assess the impact of stapled hemorrhoidopexy on anorectal function and continence. METHODS: Sixty-one patients with rectal prolapse and/or symptomatic circumferential hemorrhoidal disease, as validated by the Wexner incontinence score, were included. Anal manometric indices were measured. The Wexner scores and anal manometric measures were compared pre- and postoperatively using the Mann-Whitney U test. (A P<0.05 was considered significant.). RESULTS: Mean age was 46.8 years (range=18-80 y), with a mean follow-up time of 3 months. Fifty-one patients completed their follow-ups. For 45 patients with a Wexner score of 0 and no history of incontinence, the anal maximum squeezing pressure (AMD) was 125.3±43.1 mm Hg, the anal resting pressure (ARD) was 27.8±12.8 mm Hg, and the mean pressure was 40.0±16.8 mm Hg. The changes in the anorectal manometric indices before and 3 months after the operation were not statistically significant (P=0.99, P=0.55, and P=0.32, respectively). In 6 patients with Wexner scores of 1 or higher, the mean values of the AMD, ARD, and mean pressure not only decreased but also increased postoperatively, but the changes were not statistically significant (P=0.32, P=0.42, and P=0.45, correspondingly). CONCLUSION: These data represent a series of patients with 3 months' follow-up after stapled hemorrhoidopexy and suggest that this technique is safe in experienced hands. It may have protective effects on anorectal function in patients with imperfect continent scores. Trial Registration Number: IRCT2015101324504N1.

Early Outcome of Patient with Ulcerative Colitis who Received High Dose of Steroid and Underwent Two Staged Total Proctocolectomy.

BACKGROUND: Ulcerative colitis (UC) is an idiopathic inflammatory disorder. Currently, the final treatment is colectomy. The aim of this study was to investigate the outcomes of proctocolectomy in patients that used a high dose of prednisolone. MATERIALS AND METHODS: Seventy-five patients presenting for surgical management of histopathologically proven UC. All patients were offered total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA). Patients were divided into two groups: low dose of steroids (Group A) and high dose of steroid (Group B) consumers. Data from these patients after 2 years were reviewed and analyzed. RESULTS: From total patients, 34 of them were male and 34 ones were female and seven patients underwent laparatomy. Overall incontinence rate was 8.8%; dysplasia was 22%, pouchitis was 18.9% while mortality was nil. The length of hospital stay was 6.76 days in Group A and 9.21 days in Group B (P = 0.399). Leakage was observed in nine of the patients after surgery (P = 0.589). Fecal incontinence between two groups was not statistically different (P = 0.063). CONCLUSIONS: Laparoscopic TPC-IPAA is feasible in patients needing surgical management of UC. Preoperative treatment with high-dose corticosteroids is associated with an increased risk of complications and reoperations.
