Purpose
Fistulotomy is considered the most effective treatment for anal fistula; however, it carries a risk of incontinence. Sphincteroplasty in the setting of fistulotomy is not standard practice due to concerns regarding healing and potential infectious complications. We aimed to compare the outcomes of patients who underwent fistulotomy with primary sphincteroplasty to those who did not undergo repair.
Methods
This was a retrospective review of consecutive patients who underwent fistulotomy for cryptoglandular anal fistula. All operations were performed by one colorectal surgeon. Sphincteroplasty was performed for patients perceived to be at higher risk for continence disturbance. The main outcome measures were the healing rate and postoperative septic complications.
Results
In total, 152 patients were analyzed. Group A (fistulotomy with sphincteroplasty) consisted of 45 patients and group B (fistulotomy alone) included 107 patients. Both groups were similar in age (P=0.16) and sex (P=0.20). Group A had higher proportions of multiple fistulas (26.7% vs. 6.5%, P<0.01) and complex fistulas (mid to high transsphincteric, 37.8% vs. 10.3%; P<0.01) than group B. The median follow-up time was 8 weeks. The overall healing rate was similar in both groups (93.3% vs. 90.6%, P=0.76). No significant difference between the 2 groups was noted in septic complications (6.7% vs. 3.7%, P=0.42).
Conclusion
Fistulotomy with primary sphincter repair demonstrated a comparable healing rate to fistulotomy alone, without an increased risk of postoperative septic complications. Further prospective randomized studies are needed to confirm these findings and to explore the functional outcomes of patients who undergo sphincteroplasty.

Purpose
Most of the causes of small bowel obstruction (SBO) in patients without a history of abdominal surgery are unclear at initial assessment. This study was conducted to identify the etiology and clinical characteristics of SBO in virgin abdomens and discuss the proper management.
Methods
A retrospective review involving operative cases of SBO from a single institute, which had no history of abdominal surgery, was conducted between January 2010 and December 2020. Clinical information, including radiological, operative, and pathologic findings, was investigated to determine the etiology of SBO.
Results
A total of 55 patients were included in this study, with a median age of 57 years and male sex (63.6%) constituting the majority. The most frequently reported symptoms were abdominal pain and nausea or vomiting. Neoplasm as an underlying cause accounted for 34.5% of the cases, of which 25.5% were malignant cases. In patients aged ≥60 years (n=23), small bowel neoplasms were the underlying cause in 12 (52.2%), of whom 9 (39.1%) were malignant cases. Adhesions and Crohn disease were more frequent in patients aged <60 years. Coherence between preoperative computed tomography scans and intraoperative findings was found in 63.6% of the cases.
Conclusion
There were various causes of surgical cases of SBO in virgin abdomens. In older patients, hidden malignancy should be considered as a possible cause of SBO in a virgin abdomen. Patients with symptoms of recurrent bowel obstruction who have no history of prior abdominal surgery require thorough medical history and close follow-up.

Abstract PDF: PURPOSE
The aim of this study is to compare and analyze the histological differences between vascular and mucosal hemorrhoids, two structurally different types of hemorrhoids. METHODS: Internal hemorrhoidal tissue samples were fixed in 10% Formalin solution, and coronal sections included 10-mm proximal and 5-mm distal of the dentate line. Routine Masson-Trichrome and H&E were performed to evaluate the thickness of the mucosa and changes in the structure and the densities of submucosal vessels, connective tissue, and muscle. RESULTS: Compared with the corresponding tissues of mucosal hemorrhoids, the submucosal connective tissue and perivascular connective tissue of vascular hemorrhoids showed a loosened density, severe fragmentation, and an irregular arrangement. The submucosal vascular dilatation was more frequent and more severe in vascular hemorrhoids, but the number of vessels between both types of hemorrhoids did not show much difference. Hypertrophy and regular arrangement of the submucosal muscles were observed more frequently in the mucosal than in the vascular hemorrhoids.
CONCLUSION
Compared to mucosal hemorrhoids, vascular hemorrhoids showed augmented damage in submucosal connective tissue and intense dilatation of vessels with a thinner mucosa. On the other hand, compared to vascular hemorrhoids, mucosal hemorrhoids showed hypertrophy of submucosal muscle and relatively minor alterations in vessels with a thicker mucosa. These histological differences may provide the basis for different etiologies between vascular and mucosal hemorrhoids.

Abstract PDF: PURPOSE
Intra-abdominal adhesion related to prior abdominal surgery is the most common cause of small bowel obstruction (SBO). However, there are subsets of patients with SBO without a history of previous operation. We studied the characteristics of these patients.
METHODS
The medical records of 311 patients underwent operations at Seoul National University Hospital between Jan. 1994 and Oct. 2005 were reviewed. A retrospective analysis of the incidence, etiology, diagnostic method, preoperative hospital stay, operative findings and methods, complication rates, postoperative hospital stay, re-admission rate, and reoperation rate of SBO was performed, and the results were compared with those of patients with a history of previous operation.
RESULTS
Among the 311 patients (54.4 +/- 14.7 yr, M:F=1.5:1), 48 patients (15.3%) had no history of operation. The etiologies of SBO without a history of operation were malignancy (23.0%), bezoar (14.5%), adhesion (10.4%), Crohn's disease (10.4%), tuberculosis (8.3%), and appendicitis (8.3%). SBO without prior abdominal surgery showed a longer preoperative hospital stay, which was not statistically significant. The accuracies of CT and small bowel series among patients without a history of operation were 68.4% and 54.5%, respectively. SBO without prior abdominal surgery showed a lower complication rate (8.3% vs. 26.6%, P=0.006) and shorter postoperative hospital stays (12.7 +/- 6.9 days vs. 16.1 +/- 10.4 days, P=0.032).
CONCLUSIONS
Among the patients who underwent an operation for SBO, 15.3% had no history of previous operation. The most common cause of SBO without a history of operation was malignancy. SBO without a history of operation showed a lower complication rate and a shorter postoperative hospital stay compared with SBO with a history of operation.

Abstract PDF: Fecal incontinence is a disabling condition with devastating psychosocial impact due to diverse etiology. This study was performed to assess various causes of fecal incontinence, clinical evaluation, and adequate surgical treatment.
METHODS
Eighty patients presenting fecal incontinence during July 1989 and June 1997 were included. They were evaluated by clinical parameters and physiologic tests including the defecography, electromyography, transanal ultrasonography, and anorectal manometry. Surgery was performed in 31 patients based on those evaluation. Pre- and post-operative comparison of manometric findings, clinical assessment, incontinence score, and the outcome of surgery were assessed. Mean postoperative follow-up was 22 (2~84) months.
RESULTS
Inappropriate anal surgery was the most common cause, and then injuries during delivery, trauma, rectal prolapse, and hysterectomy in descending order. Defecography was performed in 21 patients and mean values of anorectal angles were 115+/-15degrees at rest, 98+/-18degrees during squeezing, and 136+/-10degrees during push. Electromyography was performed in 8 patients showing pudendal neuropathy in 2, bilateral lumbosacral polyradiculopathy in 4, and normal finding in 2 patients, respectively. Transanal ultrasonography was performed in 33 patients and 22 among them showed finding of an injury of the anal sphincters. Surgery was performed in 31 patients due to anal sphincter damage, rectovaginal fistula, and anal stricture in descending order. Type of surgery was determined by respective cause: plication, triple repair (sphincteroplasty, anoplasty, perineorrhaphy), and posterior rectopexy in descending order. Nerve preserving graciloplasty was performed in a 12 year-old girl who had severe defect of the anal sphincters by traffic accident, showing sound recovery with a good functional outcome. Although there was no significant difference of manometric variables between pre- and post-operative periods, sphincter length, and maximum resting and squeezing pressure, revealed an increasing tendency postoperatively. According to the clinical assessment between pre- and post-operative periods, urgency to evacuate, soiling, sensation on defecation, and quality discrimination were significantly improved postoperatively (P<0.01). Incontinence score was markedly decreased from 10.6+/-6.1 during preoperative period to 2.9+/-4.7 during postoperative period (P<0.01). Eighty one percent of the patients undergone surgery experienced a significant symptomatic improvement.
CONCLUSIONS
According to the analysis of the causes of fecal incontinence, inappropriate anal surgery, injuries during delivery, and trauma were main causes. Adequate application of physiologic tests, such as, defecography, electromyography, transanal ultrasonography, and anorectal manometry, were helpful in determining treatment modality and types of surgery. We got satisfactory results with adequate surgery based on the physiologic tests.
