Abstract PDF

Perianal fistula is a frequent complication and one of the subclassifications of Crohn disease (CD). It is the most commonly observed symptomatic condition by colorectal surgeons. Accurately classifying a perianal fistula is the initial step in its management in CD patients. Surgical management is selected based on the type of perianal fistula and the presence of rectal inflammation; it includes fistulotomy, fistulectomy, seton procedure, fistula plug insertion, video-assisted ablation of the fistulous tract, stem cell therapy, and proctectomy with stoma creation. Perianal fistulas are also managed medically, such as antibiotics, immunomodulators, and biologics including anti-tumor necrosis factor-alpha agents. The current standard treatment of choice for perianal fistula in CD patients is the multidisciplinary approach combining surgical and medical management; however, the rate of long-term remission is low and is reported to be 50% at most. Therefore, the optimum management strategy for perianal fistulas associated with CD remains controversial. Currently, the goal of management for CD-related perianal fistulas are controlling symptoms and maintaining long-term anal function without proctectomy, while monitoring progression to anorectal carcinoma. This review evaluates perianal fistula in CD patients and determines the optimal surgical management strategy based on recent evidence.

Abstract PDF

Purpose
Stapled anastomotic techniques to the distal rectum have gained widespread acceptance due to their procedural advantages. Various modifications in the stapling techniques have evolved since their inception. The triple-staple technique utilizing stapled closure of both the proximal colon and distal rectal stump provides a rapid and secure colorectal anastomosis. The aims of this study were to determine the safety and efficacy of the triple-staple technique and to compare the clinical outcomes with a historical control group for which the conventional double-staple technique had been performed.
Methods
One hundred consecutive patients operated on by a single surgeon were included in the study; 50 patients who underwent a double-staple (DSA) procedure and 50 patients undergoing triple-staple anastomosis (TSA).
Results
The most common indication for surgery in both groups was rectal cancer followed by diverticular disease and distal sigmoid cancer. There was no significant difference in number of patients requiring loop ileostomy formation in the groups (TSA, 56.0% vs. DSA, 68.0%; P = 0.621). The mean operating time for the TSA group was significantly shorter compared to that of the DSA group (TSA, 242.8 minutes vs. DSA, 306.1 minutes; P = 0.001). There was no significant difference in complication rate (TSA, 40% vs. DSA, 50%; P = 0.315) or length of hospital stay between the two groups (TSA, 11.3 days vs. DSA, 13.0 days; P = 0.246). Postoperative complications included anastomotic leak, prolonged ileus, bleeding, wound infection, and pelvic collection.
Conclusion
The triple-staple technique is a safe alternative to double-staple anastomosis after anterior resection and effectively shortens operating time.

Abstract PDF

Purpose
The treatment of acutely obstructing colorectal cancers is still a matter of debate. The prevailing opinion is that an immediate resection should be performed whenever possible. This study sought to determine whether immediate resection is safe and oncologically valid.
Methods
We completed a retrospective 2-center cohort study using the medical records of patients admitted for acutely obstructing colorectal cancer under the care of the Colorectal Team, Noble’s Hospital, Isle of Man, and the Emergency Surgery Unit, Umberto I University Hospital, Rome, from March 2013 to May 2017. The primary endpoints were 90-day mortality and morbidity, reoperation rate, and length of stay. The secondary endpoints were status of margins, number of lymph nodes retrieved, and the rate of adequate nodal harvest.
Results
Sixty-three patients were retrospectively enrolled in the study. Mortality was associated with age > 80 years and Dukes B tumors. The length of hospital stay was shorter in patients who had their resection less than 24 hours from their admission, in those who had laparoscopic resection and in those with distal tumors. The number of lymph nodes retrieved and rate of R0 resections were similar to those reported in elective colorectal surgery and were greater in laparoscopic resections and in patients operated on within 24 hours, respectively.
Conclusion
Immediate resection is a safe and reliable option in patients with acutely obstructing colorectal cancer.

Abstract PDF

Purpose
Recently, laparoscopic reversal of Hartmann’s colostomy was performed with favorable outcomes by many surgeons. We partially applied the concepts of single-port laparoscopic procedure through the colostomy site to remove intraperitoneal adhesion during initial step of the laparoscopic Hartmann’s reversal. This study aimed to evaluate the feasibility and safety of the laparoscopic reversal of Hartmann’s colostomy with the application of single-port laparoscopic techniques through the colostomy site.
Methods
From October 2008 to November 2018, the laparoscopic Hartmann’s reversal was attempted in 20 patients. After colostomy take-downs, the single-port device was installed at the colostomy site and the single-port laparoscopic procedure was performed to remove intraperitoneal adhesions to provide space for additional trocars. After additional trocars were inserted, the descending colon and rectal stump were mobilized, and the colorectal anastomosis was completed. We retrospectively reviewed the medical records and analyzed the data to identify the perioperative complication rates as the primary outcome.
Results
Of the 20 patients, 3 patients (15.0%) had open conversions due to severe adhesions. Intraoperative small bowel injuries occurred in 2 patients (10.0%) and these were repaired through the colostomy site. Postoperative complications developed in 4 patients (20.0%) and were managed with medical treatments or wound closures under local anesthesia.
Conclusion
The single-port laparoscopic procedure through the colostomy site is sufficiently safe in order to complete the Hartmann’s reversal. We recommend that the colostomy site should be used as the access route into the abdominal cavity for the Hartmann’s reversal.

Abstract PDF

Purpose
There is no clear evidence of the benefit of adjuvant chemotherapy (AC) in stage IIA colon cancer. Therefore, we aimed to evaluate the prognostic factors and survival benefit of AC in this disease.
Methods
A retrospective data collection for patients who underwent radical surgery for colon cancer between January 2008 and December 2015 was undertaken. The cohort was divided into the no-AC and AC groups.
Results
We included 227 patients with stage IIA colon cancer in our study cohort, including 67 and 160 patients in the no-AC and AC groups, respectively. The number of retrieved lymph nodes and the presence of tumor complications as obstruction or perforation were independent risk factors for survival. In the no-AC group, there was a significant difference in survival according to the number of retrieved lymph nodes. In the AC group, there were significant differences in survival according to sidedness and preoperative carcinoembryonic antigen (CEA). There was no significant difference in survival between the no-AC and the AC groups.
Conclusion
The number of retrieved lymph nodes and the presence of tumor complications were prognostic factors for stage IIA colon cancer but lymphovascular and perineural invasion were not. Sidedness and preoperative CEA could be used as factors to predict the benefit of adjuvant chemotherapy. Currently, it is believed that there is no benefit of AC for stage IIA colon cancer. Further studies are needed to determine the survival benefit of adjuvant chemotherapy in stage IIA colon cancer.

Purpose
This study aimed to evaluate the relationship between high-output stomas (HOSs), postoperative ileus (POI), and readmission after rectal cancer surgery with diverting ileostomy.
Methods
We included 302 patients with rectal cancer who underwent restorative resection with diverting ileostomy between January 2011 and December 2015. HOSs were defined as stomas with ≥ 2,000 mL/day output. We analyzed predictive factors for readmission of these patients.
Results
Forty-eight patients (15.9%) had HOSs during the hospital stay, and 41 patients (13.6%) experienced POI. HOSs were strongly associated with POI (45.8% vs. 7.5%, P < 0.001). The all-cause readmission rate was 16.9%, with 19 (6.3%) and 20 (6.6%) experiencing ileus and acute kidney injury, respectively. HOSs (27.1% vs. 15.0%, P = 0.040) and POI (34.1% vs. 14.2%, P = 0.002) were associated with all-cause readmission, and POI was associated with readmission with ileus (17.1% vs. 4.6%, P = 0.007). POI was an independent risk factor for all-cause readmission (adjusted odds ratio [OR], 2.640; 95% confidence interval [CI], 1.162 to 6.001; P = 0.020) and readmission with ileus (adjusted OR = 3.869; 95% CI 1.387 to 10.792; P = 0.010).
Conclusion
POI was associated with readmission, particularly for subsequent ileus, in patients with diverting ileostomy. We should make efforts to reduce POI, such as strong control of HOSs, to prevent readmission.

Purpose
According to recent studies, magnetic resonance imaging (MRI) assessment of complex fistulas provides a significant benefit compared to fistulography, computed tomography, and ultrasonography. The aim of this study was to describe the accuracy of MRI and the importance of identifying puborectalis muscle involvement on MRI in patients with complex fistula.
Methods
All patients who were clinically diagnosed with ‘complex’ or showed multiple fistula tracts underwent fistula MRI. Eligible patients were consecutive patients who underwent fistula MRI between September 2018 and September 2019 at our hospital.
Results
A total of 83 patients (74 males, 9 females; 116 tracts) were included in this study. The sensitivity and specificity of MRI in diagnosing fistula tracts were 94.8% and 98.2%, respectively. The sensitivity and specificity in identifying internal opening were 93.9% and 97.3%, respectively. Of the 35 patients with puborectalis muscle involvement in the MRI, 31 images of suprasphincteric-type patients on the Park’s classification were classified. The patients of puborectalis involvement were divided into 2 groups according to the surgical procedure that was performed. There were 12 sphincter-saving procedures and 19 sphincter division procedures performed. Recurrence was seen in 2 patients in the sphincter-saving procedure group, while no case was seen in the sphincter division procedure group. Five complications were found in the sphincter division procedure group, of which 2 reported incontinence.
Conclusion
Fistula MRI is a highly accurate examination for evaluating complex fistulas, and the puborectalis muscle involvement findings are very important for diagnosis and treatment.

We aimed to show that a standardized step-by-step robotic approach using surgical landmarks could make lateral pelvic lymph node dissection (LPND) less complicated. We performed robot-assisted LPND consisting of 4 steps using surgical landmarks. The first step is a dissection of uretero-hypogastric fascia, which envelopes the ureter and the hypogastric nerve. The second step is a dissection of the medial side of the external iliac vein located at the lateral border of the obturator lymph nodes (LNs) group. The third step is a dissection of the vesico-hypogastric fascia, which is at the medial border of the obturator LNs group. The final step is a dissection of the internal iliac artery until the Alcock’s canal. Indocyanine green was injected just before surgery around the dentate line to identify the lateral pelvic LNs. Standardization using a robotic approach for LPND guided by surgical landmarks allows a safer and more effective surgery.

Abstract PDF

Pelvic kidney, an ectopic renal mass caused by developmental failure, is a rare condition. Here, we report a case of laparoscopic anterior resection in a patient with a solitary pelvic kidney. A 76-year-old man was diagnosed as having rectosigmoid colon cancer. Preoperative computed tomography revealed a left ectopic kidney in his pelvis. Computed tomographic angiography and retrograde pyelography were performed preoperatively to identify the renal vessels and the ureter. To keep the surgical plane intact for complete mesocolic excision, a complete laparoscopic anterior resection was safely performed without open conversion, and there was no injury to the pelvic kidney. The patient was discharged on postoperative day eight without any complication. No deterioration of renal function was observed after surgery. This report describes a case of laparoscopic anterior resection that was safely performed without conversion to open surgery in a patient with a pelvic ectopic kidney.

Abstract PDF

Malignant melanoma of the anorectum is a rare disorder. Patients often present with local symptoms similar to benign diseases. The prognosis is very poor, and almost all patients die because of metastases. We report 2 female patients with unremarkable histories. Both of them received previous operations before visiting our center after they were diagnosed with anorectal malignant melanoma. One case underwent abdominoperineal resection and postoperative chemotherapy. The other had been treated with ultralow anterior resection followed by immunotherapy.
