Abstract

- Purpose
Anastomotic bleeding after colorectal surgery is a rare, mostly self-limiting, postoperative complication that could lead to a life-threatening condition. Therefore, prompt management is required. This study aimed to evaluate the efficacy and safety of endoscopic clipping for acute anastomotic bleeding after colorectal surgery.
Methods
We retrospectively reviewed the data of patients pathologically diagnosed with colorectal cancer at National Cancer Center, Korea from January 2018 to November 2020, which presented with anastomotic bleeding within the first postoperative week and were endoscopically managed with clips.
Results
Nine patients had anastomotic bleeding, underwent endoscopic management, and, therefore, were included in this study. All patients underwent laparoscopic (low/ultralow) anterior resection with mechanical double-stapled anastomosis. Anastomotic bleeding was successfully managed through a colonoscopy with clips on the first trial in all patients. Hypovolemic shock occurred in one patient, following anastomotic breakdown.
Conclusion
Endoscopic clipping seems to be an effective and safe treatment for anastomotic bleeding with minimal physiologic stress, easy accessibility, and scarce postoperative complications. However, a surgical backup should always be considered for massive bleeding.

Abstract
PDF
- Purpose
The surgical management of patients with full-thickness rectal prolapse (FTRP) continues to remain a challenge in the laparoscopic era. This study retrospectively assesses a cohort of patients undergoing a transanal suture sacro rectopexy supported by sclerosant injection into the presacral space under ultrasound guidance.
Methods
Patients with FTRP underwent a sutured transrectal presacral fixation of 2/3 of the circumference of the rectum from the third sacral vertebra to the sacrococcygeal junction through a side-viewing operating proctoscope. The procedure was supplemented by ultrasound-guided injection into the retrorectal space of a 2 mL solution of sodium tetradecyl sulfate/polidocanol mixed with air. Patients were functionally assessed before and 6 months after surgery with the Agachan constipation score and the Pescatori incontinence score.
Results
There were 36 adult patients (26 males; the range of age, 23–92 years). The mean operative time was 27 minutes (range, 23–50 minutes) with no recorded perioperative morbidity. The median follow-up was 66 months (range, 48–84 months) with 1 (2.8%) recurrence presenting 18 months after surgery. There were 19 patients (52.8%) who presented with incontinence before surgery with 17 out of 19 (89.5%) reporting improvement in their Pescatori score (P<0.001). No patient had worsening incontinence and there were no de novo incontinence cases. Constipation scores improved in 23 out of 36 patients (63.9%) with a mean score reduction difference of 7.91 (P=0.001).
Conclusion
Transanal sutured sacral rectopexy with supplemental presacral sclerosant injection is safe and effective in the management of FTRP with sustained improvement in bowel function.

Abstract

- Congenital factor V (FV) deficiency is a rare hemorrhagic disorder that can cause excessive bleeding during and after surgery in the affected patient. This report is the case of a patient who had FV deficiency with recurrent posthemorrhoidectomy bleeding treated with the hemostatic procedure and fresh frozen plasma (FFP) transfusions. A 45-year-old male patient had previously undergone hemorrhoidectomy for multiple hemorrhoids at a local hospital. Hemorrhoidectomy was successful; however, he was transferred to our hospital for evaluation of the origin of the recurrent posthemorrhoidectomy bleeding and underwent a hemostatic procedure. This bleeding was treated with coagulation using electrocautery, multiple sutures, and FFP transfusion (1,600 mL/day) for 7 consecutive days. The patient’s plasma FV activity was 23%. Early detection of clotting factor deficiency in patients with hemorrhagic events after surgical treatments may prevent unnecessary procedures such as reoperations and minimize the cost of replacement therapy such as large-volume FFP transfusion.

Abstract
PDF
- Purpose
The aim of this study was to assess frequency and risk factors of severe bleeding after proctological surgery requiring hemostatic surgery observed after publication of the French guidelines for anticoagulant and platelet-inhibitor treatment.
Methods
All patients who underwent proctological surgery between January 2012 and March 2017 in a referral center were included. Delay, severity of bleeding, and need for blood transfusion were recorded. Patients with severe postoperative bleeding were matched to controls at a 2:1 ratio adjusted on the operator, and the type of surgery.
Results
Among the 8,890 operated patients, 65 (0.7%) needed a postoperative hemostatic procedure in an operating room. The risk of a hemostatic surgery was significantly increased after hemorrhoidal surgery compared with other procedures (1.9% vs. 0.5%, P<10–4) and was most frequent after Milligan-Morgan hemorrhoidectomy (2.5%). Mean bleeding time was 6.2 days and no bleeding occurred after day 15. Blood transfusion rate was 0.1%. Treatment with anticoagulants and platelet inhibitors were managed according to recommendations and did not increase the severity of bleeding. The risk of severe bleeding was significantly lower in active smokers vs. non-smokers in univariate (16.9% vs. 36.2%, P=0.007) and multivariate (odds ratio, 0.31; 95% confidence interval, 0.14–0.65) analysis whereas sex, age, and body mass were not significantly associated with bleeding.
Conclusion
Severe postoperative bleeding occurs in 0.7% of patients, but varies with type of procedure and is not affected by anticoagulant or antiplatelet treatment. These treatments given in accordance with the new guidelines do not increase the severity of postoperative bleeding.

Abstract

- Colonic mucosal injury is rare, but may severely fatal, complications following the administration of calcium polystyrene sulfonate resins. The incidence rate is about 0.57%, administered without sorbitol, and increases to 1.8% when it is concomitant with sorbitol, especially in postoperative patients. In this case report, we demonstrated the case of a 77-year-old female with stage 3b chronic kidney disease presented with in-hospital hematochezia after 3 weeks of calcium polystyrene sulfonate administration. The colonoscopic findings showed several serpiginous ulcers with some oozing at descending and sigmoid colon. The histological findings revealed some focal inflammation and ulcerations with crystal-like materials, compatible with cation exchange resins. The recent in vitro study, explaining the pathogenesis of cation exchange resin-associated colonic mucosal injury, was also reviewed.

Abstract
PDF
Prostate cancer is commonly diagnosed by using a transrectal ultrasound (TRUS)-guided biopsy. Although this procedure is usually well tolerated, rarely it may be complicated by massive rectal bleeding. We report a case of a 77-year-old male who underwent a TRUS biopsy and subsequently developed recurrent episodes of rectal bleeding with syncope and anemia requiring the transfusion of multiple units of blood. A sigmoidoscopy revealed the source of the bleeding: a large hemorrhoid on the anterior wall of the rectum with an overlying ulceration. We successfully applied a band to ligate the hemorrhoid, and the patient's condition improved. To our knowledge, this case represents the first report of a successful band ligation to treat massive bleeding from a hemorrhoid that had been punctured in the course of the TRUS biopsy procedure.

Abstract
PDF
Intramural colonic hemorrhage is rare and often secondary to trauma or anticoagulation therapy. Idiopathic intramural hemorrhages in the alimentary tract have rarely been reported. While several reports of spontaneous perforation of an intramural rectal hematoma have been published, no reports of spontaneous perforation in the ascending colon due to a hematoma have. We describe a patient with an ascending colonic perforation secondary to spontaneous intramural hemorrhage. The patient is a 35-year-old male, who presented with acute abdominal pain and no history of trauma. An abdominal computed tomography scan showed a high-density area around the ascending colon, and nonoperative management was instituted. On the eighth hospital day, the pain worsened, and abdominal computed tomography scan showed free air. An emergent right hemicolectomy was performed. Intramural hematoma and ischemia with perforation, with no obvious etiology, were found. The patient was discharged on the 14th postoperative day.

Abstract
PDF
Stapled transanal rectal resection (STARR) and stapled hemorrhoidopexy (SH) are well-established techniques for treating rectal prolapse and obstructed defecation syndrome (ODS). Occasionally, they can be associated with severe complications. We describe the case of a 59-year-old woman who underwent STARR for ODS and developed a postoperative pelvic hemorrhage. A computed tomography (CT) scan revealed a vast pelvic, retroperitoneal hematoma and free gas in the abdomen. Laparoscopy ruled out any bowel lesions, but identified a hematoma of the pelvis. Flexible sigmoidoscopy showed a small leakage of the rectal suture. The patient was treated conservatively and recovered completely. Surgeons performing STARR and SH must be aware of the risk of this rare, but severe, complication. If the patient is not progressing after a STARR or SH, a CT scan can be indicated to rule out intra-abdominal and pelvic hemorrhage. Laparoscopy is a diagnostic tool and should be associated with intraluminal exploration with flexible sigmoidoscopy.

Abstract
PDF
Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleeding from the orifice of the appendix. We performed a laparoscopic appendectomy. Microscopically, dilated veins were found at the submucosal layer of the appendix. The patient was discharged uneventfully. Although lower gastrointestinal bleeding of appendiceal origin is very rare, clinicians should consider it during differential diagnosis.

- Purpose
Injection sclerotherapy for hemorrhoids has been performed for many years. Currently, 5% phenol in almond oil (PAO) and aluminum potassium sulfate and tannic acid (ALTA) are used as the agents. The purpose of this study was to compare the efficacy of the two agents.
MethodsA retrospective study was conducted involving 135 patients who underwent injection therapy for grade 3 hemorrhoids for the first time between 2013 and 2014 (PAO, 55 patients; ALTA, 80 patients). The efficacy was established as the proportion (%) of patients without symptoms such as hemorrhage and prolapse one year after treatment. We investigated four factors—sex, age, number of hemorrhoids, and agent—that might have an influence on the efficacy.
ResultsThe efficacies of ALTA and PAO one year after treatment were 75% and 20%, respectively. Only the agent was a significant independent factor (P < 0.01).
ConclusionThe results suggest that ALTA is markedly more useful than PAO for injection sclerotherapy for grade 3 hemorrhoids.

- Purpose
A colonoscopic polypectomy is an important procedure for preventing colorectal cancer, but it is not free from complications. Delayed hemorrhage after a colonoscopic polypectomy is one infrequent, but serious, complication. The aim of this study was to identify the risk factors for delayed hemorrhage after a colonoscopic polypectomy.
MethodsThis was a retrospective case-control study based on medical records from a single gastroenterology center. The records of 7,217 patients who underwent a colonoscopic polypectomy between March 2002 and March 2012 were reviewed, and 92 patients and 276 controls were selected. Data collected included comorbidity, use of antiplatelet agents, size and number of resected polyps, histology and gross morphology of resected polyps, resection method, and use of prophylactic hemostasis.
ResultsThe average time between the procedure and bleeding was 2.71 ± 1.55 days. Univariate and multivariate analyses revealed that the size of the polyps was the only and most important predictor of delayed hemorrhage after a colonoscopic polypectomy (odds ratio, 2.06; 95% confidence interval, 1.12-1.27; P = 0.03).
ConclusionThe size of resected polyps was the only independent risk factor for delayed bleeding after a colonoscopic polypectomy. The size of a polyp, as revealed by the colonoscopic procedure, may aid in making decisions, such as the decision to conduct a prophylactic hemostatic procedure.

Abstract

- Purpose
The colonoscopic polypectomy has become a valuable procedure for removing precursors of colorectal cancer, but some complications can be occurred. The most common complication after colonoscopic polypectomy is bleeding, which is reported to range from 1% to 6% and which can be immediate or delayed. Because the management of delayed postpolypectomy bleeding could be difficult, the use of preventive technique and reductions of risk factors are essential.
MethodsFrom January 2007 to December 2008, delayed hemorrhage occurred in 18 of the 1,841 polypectomy patients examined by one endoscopist. These cases were reviewed retrospectively for risk factors, pathologic findings, and treatment methods.
ResultsDelayed bleeding occurred in 18/1,841 patients (0.95%). The mean age was 55.9 ± 10.9 years, and the male-to-female ratio was 8:1. The most common site was the right colon (11 cases, 61.1%), and the average polyp size was 9.2 ± 2.8 mm. Delayed bleeding was identified from 1 to 5 days after resection (mean, 1.6 ± 1.2 days). The most common macroscopic type of polyp was a sessile polyp (10 cases, 55.6%), and histologic finding was a tubular adenoma in 13 cases (72.2%). Seventeen cases were treated with clipping for hemostasis and 1 case with epinephrine injection.
ConclusionThe right colon and a sessile polyp were associated with an increase in delayed postpolypectomy bleeding. Reducing risk factors and close observation were essential in high risk patients, and prompt management with hemoclips was effective.

Abstract
PDF
- A benign cecal ulcer is an uncommon lesion. The etiology remains unknown, and there are no pathognomonic lesions or symptoms. Lower gastrointestinal tract hemorrhage secondary to benign cecal ulcer is the most common complication.
Herein, the case of a 24-year-old man with a benign cecal ulcer presenting with a massive lower gastrointestinal tract hemorrhage requiring transfusion until a exploratory laparotomy and right hemicolectomy, is reported with a review of the literature. Surgical intervention is warranted if malignancy is suspected or if the patient has signs of uncontrollable hemorrhage, perforation, or peritonitis.

- PURPOSE
This study reviews our experience with a step- by-step management approach of increasing aggressiveness and evaluates the treatment outcome for intraluminal hemorrhage.
METHODS
The study group was comprised of patients who had experienced intraluminal hemorrhage after a low anterior resection with the double stapling technique from 1999 to 2003. The choice of management was selected according to our step-by-step management protocol, and the outcomes were evaluated for each step, lincluding mortality and complications.
RESULTS
Nine patients (6 males and 3 females, mean age 55 years) were identified, the mean volume of packed RBC transfusion was 2 pints, and the mean distance of the anastomotic site from the anal verge was 6 cm. The median stapler size was 31 mm. The first step was cold saline irrigation and drainage; four of 9 patients were controlled.
The second step was retention enema with topical hemostatics; one of remaining 5 patients stopped bleeding.
The third step was colonoscopic hypertonic saline injection around the bleeding site with direct colonoscopic electrocauterization, two of remaining 4 patients were controlled. The last step was suturing the bleeding site through the anus, the remaining 2 patients stopped bleeding.
One of the 9 patients developed leakage from the anastomotic site after the last step management, three of the 9 patients had long standing ileus, and one of the 9 patients developed acute renal failure after a massive transfusion. There were no postoperative deaths.
CONCLUSIONS
It is safer and easier to control bleeding with step-by-step management system of increasing aggressiveness.

Abstract

- PURPOSE
Post-hemorrhoidectomy secondary hemorrhage is a rare but serious complication after a hemorrhoidectomy. This study analyzed the factors associated with secondary hemorrhage following a surgical hemorrhoidectomy.
METHODS
A total of 1,751 patients received a semiclosed hemorrhoidectomy for symptomatic hemorrhoidal disease from May 2001 to January 2004. A retrospective study of 17 patients with post-hemorrhoidectomy secondary hemorrhage was done. Fourteen patients (82 percent) underwent surgery primarily for hemorrhoidal disease, two patients (12 percent) had hemorrhoids removed in addition to a sphincterotomy for anal fissure, and the remaining patient (6 percent) had a hemorrhoidectomy with fistulectomy. The variables analyzed included age, gender, incidence, recurrence, hospitalization, bleeding tendency, blood transfusion, and management.
RESULTS
The male to female ratio was 1.83:1 (P>0.05), and the mean age was 38.9 (range 19~55) years. The incidence of post-hemorrhoidectomy secondary hemorrhage was 0.98 percent.
The mean interval from the operation to hemorrhage was 8.9 (range 4~18) days. The period of mean hospitalization was 4.5 (range 2~8) days. As predisposing factors, 3 patients had suspected liver disease with normal platelet count. The mean 1.90 gm/dl of Hgb at the time of secondary hemorrhage was lower than the preoperative values. One patient (5.9 percent) required 3 units of red blood cell transfusions.
Treatment modalities included observation alone in three patients (18 percent), and suture ligation in the operating theater in fourteen patients (82 percent). None of the patients developed recurrent bleeding.
CONCLUSIONS
Post-hemorrhoidectomy secondary hemorrhage is an inevitable and a troublesome complication. The patient will need to be transferred rapidly to a hospital and resuscitated if necessary. The author favors suture ligation in controlling secondary hemorrhage. Suture ligation offers a good outcome with virtually no risk of recurrent bleeding.
Post- hemorrhoidectomy secondary hemorrhage usually occurs at home between the fourth and eighteenth postoperative day and takes place in 0.98 percent of hemorrhoidectomies. In the author's opinion, post-hemorrhoidectomy secondary hemorrhage usually is not a preventable complication.
