Abstract PDF

Complications after colorectal surgery remain inevitable, and anastomotic leakage is one of the most severe and potentially fatal complications. Generally, anastomotic leakage is associated with severe peritonitis, the need for emergency reoperation, and an increased mortality rate. Additionally, particularly after rectal cancer surgery, it has a negative impact on long-term outcomes, including postoperative anorectal function, local recurrence, and survival. To prevent anastomotic leakage, understanding the characteristics of each anastomotic technique and establishing a stable anastomotic procedure are important. Transanal total mesorectal excision (TaTME) is a relatively new advanced surgical access technique for pelvic dissection and facilitates different anastomotic techniques without the need for transabdominal rectal transection. Especially, stapled anastomosis in TaTME, also known as double purse-string circular stapled anastomosis or the single stapling technique (SST), has gained much attention as an alternative to the conventional double stapling technique (DST). In this article, we describe the DST, SST, and hand-sewn anastomosis as anastomotic techniques after rectal surgery, focusing mainly on the differences between conventional anastomotic techniques and SST in TaTME. Furthermore, the blood flow evaluation method for the reconstructive colon before anastomosis, which is extremely important in anastomotic leakage prevention regardless of the anastomotic type, is also described.

Abstract PDF

Purpose
Intestinal fibrosis is a common complication of inflammatory bowel diseases. However, the possible involvement of epithelial-mesenchymal transition (EMT) has been scarcely investigated. This systematic review aims to search through research papers that are focusing on messenger RNA (mRNA) and protein expression profile in EMT in fistula or in intestinal fibrosis.
Methods
Electronic exploration was performed until April 24, 2019 through PubMed, Ovid, Science Direct, and Scopus databases with the terms of “fistula” OR “intestinal fibrosis” AND “epithelial-mesenchymal transition”. Two independent reviewers scrutinized the suitability of the title and abstract before examining the full text that met the inclusion criteria. For each study, the sample types that were used, methods for analysis, and genes expressed were identified. The list of genes was further analyzed using DAVID (Database for Annotation, Visualization, and Integrated Discovery) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway.
Results
There were 896 citations found; however, only 3 studies fulfilled the requirements. Among the EMT-related genes, 5 were upregulated genes at mRNA level while 6 were at protein level. However, only 2 downregulated genes were found at each mRNA and protein level. Of the 4 inflammation-related genes found, 3 genes were upregulated at mRNA level and 1 at protein level. These genes were confirmed to be involved in the development of inflammatory induced fibrosis and fistula through EMT. Results from quantitative real-time polymerase chain reaction analysis were consistent with the process of EMT, confirmed by the western blot protein analysis.
Conclusion
Many significant genes which are involved in the process of EMT in fistula and intestinal fibrosis have been identified. With high-end technology many more genes could be identified. These genes will be good molecular targets in the development of biomarkers for precision drug targeting in the future treatment of intestinal fibrosis and fistula.

Graphical Abstract Abstract PDF

Purpose
Harvesting at least 12 lymph nodes (LNs) is recommended for adequate tumor staging in colon surgery. Although preoperative endoscopic tattooing has been used for primary localization of tumors, its impact on LN retrieval in colorectal surgery remains controversial. We aimed to investigate the relationship between preoperative tattooing and LN retrieval after laparoscopic rectal resection.
Methods
We reviewed the records of 92 patients with rectal cancer who underwent laparoscopic resection from January 1, 2018 to December 31, 2019. Patients were categorized into 2 groups according to whether preoperative endoscopic tattooing was performed. The rate of adequate LN retrieval (≥12) was compared.
Results
The tattooed and non-tattooed groups comprised 49 and 43 patients, respectively. In the tattooed and non-tattooed groups, the rates of adequate LN retrieval were 75.5% and 55.8%, respectively (P=0.046). Univariate analysis revealed that female sex, tattooing, LN metastasis status, pathological pathological stage (p-stage), and LN dissection were predictive factors for adequate LN retrieval. In the multivariate analysis, female sex (odds ratio [OR], 3.34; 95% confidence interval [CI], 1.15–9.73; P=0.027), tattooing (OR, 2.87; 95% CI, 1.03–7.94; P=0.043), and p-stage (OR, 3.34; 95% CI, 1.04–10.75; P=0.043) were independent predictive factors for adequate LN retrieval after surgery.
Conclusion
This study revealed that preoperative endoscopic tattooing was statistically significantly associated with adequate LN retrieval in patients with rectal cancer who underwent laparoscopic rectal resection. Preoperative endoscopic tattooing should be considered to improve disease assessment and avoid stage migration.

Abstract PDF: Purpose
In the West, diverticular disease is located mainly in the left colon. However, it can also present in the right colon, with an incidence of 1% to 2% in Caucasians. The purpose of this study was to describe our experience in right-sided acute diverticulitis (RD).
Methods
In this retrospective study, 410 patients with acute diverticulitis treated from 2013 to 2020 were included in a university hospital in Córdoba, Argentina. Colonic diverticulitis was stratified into 2 groups; RD and left-sided acute diverticulitis. Demographic and clinical variables, laboratory and imaging findings, type of treatment, follow-up, and recurrence were analyzed.
Results
Sixteen patients (3.9%) with RD were identified; 62.5% were male and the mean age was 40.7±11.7 years. A total of 81.3% were Caucasian and 18.7% Native American. Significant differences were found between both groups of diverticulitis; patients with RD were younger (P=0.001), with lower BMI (P=0.01), comorbidity rate (P=0.01), Charlson comorbidity index (P=0.02), hospital stay (P=0.01), severity according to the Hinchey classification (P=0.001) and had a lower recurrence rate (P=0.001). There were no significant differences in sex (P=0.95), duration of pain until admission (P=0.05), laboratory findings (P=0.23) and treatment (P=0.34).
Conclusion
Conservative treatment predominated in RD, with a lower rate of complications and recurrences, providing data that support conservative therapy as initial treatment in RD in our environment.

Graphical Abstract Abstract PDF

Purpose
Acute anal fissure, a disease characterized by severe pain in the anorectal area, reduces quality of life and becomes chronic absent appropriate treatment. More recently, anaerobic infections have been noted as contributive to etiopathogenesis. This study investigates topical metronidazole’s effect in the treatment of acute anal fissure.
Methods
Our prospective randomized controlled double-blind study included 2 groups of 100 patients older than 18 years from our General Surgery Clinic with anal fissure complaints for less than 8 weeks. Topical diltiazem treatment was started in group 1, and topical diltiazem and metronidazole treatment in group 2. Pain levels were evaluated by the visual analogue scale (VAS) score, and recovery status was evaluated by physical examination findings ab initio and at the 1st, 4th, and 6th weeks. VAS score levels, demographic, clinical, and recovery status were then compared.
Results
There was no difference between the groups as to age, sex, pain on defecation, bleeding, constipation, and duration of pain, bleeding and constipation (P>0.05). From week 1, fissure epithelialization and healing rates were higher in group 2 (P<0.001); group 2 VAS score levels were lower than in group 1 (P<0.001) and achieved by group 1 only in week 4 (P=0.073).
Conclusion
Adding topical metronidazole to treatment reduces the duration and severity of pain, shortens healing time, and increases the healing rate.

Abstract PDF: Purpose
Healing of colorectal anastomosis is burdened with a number of risk factors and the development of leak carries with it higher morbidity and mortality associated not only with worse quality of life but also worse oncological outcomes. The purpose of the study was an evaluation of the effect of reinforcement suture in the healing of stapler rectal anastomosis and risk factors for anastomotic leakage in mid, upper rectal and sigmoid tumors.
Methods
A total of 357 patients who underwent curative resection for rectal or sigmoid tumor over 5 years were analyzed. Risk factors, baseline demographic and clinical data, and presence of leak were recorded. All statistical analyses were carried out at a significance level of P<0.05.
Results
One hundred fifty-one patients met the inclusion criteria for the study. The overall incidence of leak was 2.8% in the group with reinforcement suture and 6.3% in the group without reinforcement suture. Because of the low incidence of leak the results were not statistically significant. Further results also show that none of the monitored parameters (age, weight, body mass index, tumor distance, preoperative radiotherapy, tumor stage, type of surgery) were significant predictors of anastomotic leakage.
Conclusion
Although the reinforcement suture is a safe and simple option for anastomosis protection after rectal or sigmoid resections, its statistical significance was not demonstrated in our study.

Abstract PDF

Purpose
Laparoscopic right hemicolectomy (LRH) can be performed with an intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA). It is not clear which technique is best. This study evaluated the impact of each anastomosis technique on perioperative safety and postoperative evolution.
Methods
We performed a retrospective study at a tertiary colorectal surgery center. All patients who had an elective LRH from 2015 to 2019 were analyzed according to the anastomosis technique used.
Results
In total, 285 patients were included in the study. IA was performed in 64 patients (22.5%). Mean operative time was longer in the patients with IA (IA, 160±31 minutes vs. EA, 138±42 minutes; P<0.001). No differences were observed in intraoperative complications, time to first bowel movement, length of stay, reoperation, or rehospitalization. Time to first flatus was longer in the patients with IA (P=0.049). At 30 days after surgery, there were no differences in the frequency of anastomotic leak (IA, 0% vs. EA, 2.3%; P=0.59), bleeding (IA, 3.1% vs. EA, 2.7%; P>0.99), or intraabdominal abscess (IA, 0% vs. EA, 0.5%; P>0.99). During follow-up, we noted more incisional hernias in patients with EA (IA, 1.6% vs. EA, 11.3%; P=0.01) and a trend toward more hernia in patients with EA in multivariate analysis (hazard ratio, 7.13; P=0.06). Anastomosis technique had no influence on recurrence.
Conclusion
For LRH, both IA and EA are safe, with a low incidence of complications when performed by experienced surgeons. IA may be associated with a lower incidence of incisional hernia.

Purpose
The albumin to globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC.
Methods
The study subjects consisted of 273 Japanese individuals with UC. AGR was divided into 4 categories (low, moderate, high, and very high). The definition of complete mucosal healing (MH) was based on the Mayo endoscopic subscore of 0. Clinical remission (CR) was defined as no rectal bleeding and no abnormally high stool frequency (<3 times per day).
Results
The percentage of MH was 26.4%. High AGR and very high AGR were significantly positively correlated with CR (adjusted odds ratio [OR], 5.85; 95% confidence interval [CI], 2.52–14.18 and adjusted OR, 4.97; 95% CI, 2.14–12.04) and complete MH (adjusted OR, 4.03; 95% CI, 1.56–11.51 and adjusted OR, 5.22; 95% CI, 1.97–14.89), respectively after adjustment for confounding factors (P for trend=0.001). Only in the low C-reactive protein (CRP) group (≤0.1 mg/dL), very high AGR was significantly positively correlated with complete MH but not CR (adjusted OR, 4.38; 95% CI, 1.06–21.77; P for trend=0.017). In the high CRP group, no correlation between AGR and complete MH was found.
Conclusion
Among Japanese patients with UC, AGR may be independently positively correlated with complete MH. In particular, among UC patients with low CRP, AGR might be a useful complementary marker for complete MH.

Abstract PDF

Purpose
Hemorrhoidal disease remains a common condition that can have a significant effect on a patient’s quality of life. Various methods have been introduced over the years; however, their overall success rates remain low. Although the traditional Milligan Morgan technique is effective, the associated pain level prevents it from being an attractive form of treatment. This study was devised to assess the safety and efficacy associated with a novel minimally invasive approach, radiofrequency ablation (RFA).
Methods
Forty-two patients underwent RFA at a single center, by 1 of 2 surgeons. This was performed under local anesthetic and sedation. Outcomes including postoperative pain levels, recurrence rates, and patient satisfaction scores were recorded and analyzed using medians and interquartile ranges
Results
The median postoperative pain score was 2.5/10 (interquartile range [IQR], 0–4.5) and the overall patient satisfaction score was 9 out of 10 (IQR, 6.5–10). Recurrence rates (6–12 months following the procedure) were low at 12% and all patients reported milder symptoms at recurrence. There were no serious adverse complications
Conclusion
The results from this case series supports other limited data in concluding that RFA is a safe and effective method in the treatment of hemorrhoids and patients report a high level of satisfaction following

Purpose
One of the most common ileostomy-related complications is high output stoma (HOS) which causes significant fluids and electrolytes disturbances. We aimed to analyze the incidence, severity, and risk factors for readmission for HOS.
Methods
We reviewed all patients who underwent loop ileostomy closure in a single institution between 2010 and 2020. Patients that were readmitted for dehydration due to HOS during the time interval between the creation and the closure of the stoma were identified and divided into a study (HOS) group. The remaining patients constructed the control group.
Results
A total of 307 patients were included in this study, out of which, 41 patients were readmitted 73 times (23.7% readmission rate) for the HOS group, and the remaining 266 patients constructed the control group. Multivariate analysis identified; advanced American Society of Anesthesiologists (ASA) physical status (PS) classification, elevated baseline creatinine, and open surgery as risk factors for HOS. Renal function worsened among the entire cohort between the construction of the stoma to its closure (mean creatinine of 0.82 vs. 0.96, P<0.0001).
Conclusion
Loop ileostomy formation is associated with a substantial readmission rate for dehydration as a result of HOS, and increasing the risk for renal impairment during the duration of the diversion. We identified advanced ASA PS classification, open surgery, and elevated baseline creatinine as predictors for HOS.

Abstract PDF

Metachronous carcinoma at the colostomy site is very rare after abdominoperineal resection. A 53-year-old male patient underwent an abdominoperineal resection 6 years earlier for rectal cancer developed metachronous carcinoma at the site of stoma. A portion of the colon, including the stoma and the surrounding skin, was resected and a new stoma was created in the transverse colon. Although the occurrence of carcinoma at the stoma site is a rare condition, careful observation for the stoma and colonoscopy for surveillance are necessary.

Abstract PDF

Malakoplakia is a rare granulomatous inflammatory disorder. Its diagnosis depends on histopathological findings; however, high-quality literature regarding proper medical/surgical treatment is lacking. A 38-year-old diabetic female patient was admitted to the emergency room with a history of lower gastrointestinal hemorrhage. Colonoscopy revealed a lesion in the descending colon, and abdominal computed tomography revealed a splenic flexure mass involving the lower pole of the spleen and upper pole of the left kidney. Biopsies confirmed the diagnosis of malakoplakia. After completing antibiotic treatment, a restaging computed tomography revealed a discrete mass increase; hence, the patient underwent laparoscopic en bloc colectomy and partial nephrectomy. Postoperatively, the patient developed a pancreatic fistula, which was successfully treated with percutaneous drainage and antibiotics. The presence of pathognomonic Michaelis-Gutmann inclusions on histopathology is frequently reported as the key to diagnosing malakoplakia. Herein, we present a successful, minimally invasive surgical treatment for colonic malakoplakia.

Abstract PDF

An Amyand’s hernia is characterised as the presence of the appendix in an inguinal hernial sac. During laparoscopic cholecystectomy for gallbladder polyps, an incidental Amyand’s hernia was discovered in a 75-year-old female patient. On examination, the hernia contained an appendiceal mucocele but no evidence of perforation. An open appendicectomy with tension-free mesh repair was performed for the hernia. The histopathological report of the appendix was a low-grade appendiceal mucinous neoplasm (LAMN), an entity that is just as rare as an Amyand’s hernia. The patient had the right inguinal swelling for over 10 years but it was thought to be an inguinal intramuscular cyst as reported on a previous abdominal ultrasound. Mucocele of the appendix may have a benign or malignant appendiceal progress, leading to individualised diagnosis and treatment. We review an Amyand’s hernia with LAMN and discuss the asymptomatic tendency yet malignant potential of appendiceal mucoceles along with treatment strategies.
