PURPOSE: Anal problems due to ingested foreign bodies are rare and usually present as acute anal pain. However, various clinical presentations are possible. This study was performed to identify the diverse manifestations of and the outcomes of treatments for anal diseases caused by ingested foreign bodies. METHODS: Between September 1995 and June 2003, seven patients were treated for anal diseases due to the impaction of ingested foreign bodies in Seoul National University Hospital and Daehang Hospital. We retrospectively reviewed the medical records of those unusual patients. RESULTS: All patients were males, and their mean age was 49.4 yr (range, 37 to 74 yr). The detected foreign bodies were fish bones (n=3), fish fins (n=2), a chicken bone (n=1), and a toothpick (n=1). Four patients had acute anal pain as the primary symptom while two patients presented anal pus discharge, and one patient presented anal bleeding. In the four patients with acute anal pain, the foreign bodies were easily found on digital rectal examination and inspection with anoscopy. Those patients underwent simple removal of the foreign body at the outpatient clinic. In three patients, the foreign bodies were found during surgery for hemorrhoids or fistulas. The two fistulas detected were complex types and needed seton placement. CONCLUSION: Anal problems caused by ingested foreign bodies usually involve acute anal pain, but our results indicate that, in some cases, the anal foreign bodies are also the cause or an aggravating factor in chronic anal disease.

PURPOSE: Partial obstruction of the small bowel causes hypertrophy of smooth muscle cells and enteric neurons. After small bowel obstruction, slow waves have also been reported to disappear or to be greatly reduced at the oral site of the obstruction in the murine ileum. The purpose of this research was to study the changes in migrating motor complexes (MMCs) after partial obstruction in order to compensate for the attenuated function of slow waves. METHODS: A ring of film (6 mm in length, 4 mm in internal diameter) was placed over the small intestine 5-6 cm oral to the ileocecal valve in 8-10 wk old female ICR mice. These rings resulted in a partial obstruction of the intestine after 2 wk. The mechanical activities of the small intestine were recorded and the amplitude, interval, and half-duration of the MMCs were analyzed. RESULTS: The MMCs from a partially obstructed ileum occurred every 1.58+/-1.06 min and had a half-duration of 6.90+/-5.54 sec. The interval and the half-duration of the control MMCs were 3.60+/-1.11 min and 31.5+/-11.4 sec, respectively. The difference in interval and the half-duration of the MMCs reached statistical significance (P=0.03; P=0.00). The amplitude and the area under the curve (AUC) of the MMCs of the obstructed ileum were much higher than those of the control (31.3+/-8.86 vs. 6.05+/-1.92 mN; 161.18+/-44.09 vs. 72.95+/-2.45 mN . sec/MMC wave; P=0.00, 0.02). CONCLUSION: The MMCs with higher amplitude and AUC, with shorter interval, and with shorter half-duration, compared with those of the control, were recorded from the partially obstructed murine ileum, reflecting efforts to overcome the effect of obstruction by increasing the power of contractions.

PURPOSE: The incidence of hernia is estimated to be 3~5% in the general population. In patients on continuous ambulatory peritoneal dialysis (CAPD), the incidence of hernia is 6~25% and immediate surgical treatment is critical to maintain CAPD. This study was performed to identify clinical characteristics of hernias in CAPD patients and evaluate the surgical results. METHODS: We retrospectively analyzed 13 prospectively registered patients (male:female=12:1) on CAPD treated with hernia between March 1998 and June 2008 at the Seoul National University Hospital by one surgeon. Perioperatively, patients underwent intermittent hemodialysis via internal jugular catheter indwelled just before the operation. Peritoneal dialysis was resumed between 2 weeks and 2 months after operation. RESULTS: Mean age was 46.6 years (range: 19~71 years). Fifteen hernias developed in 13 patients, of which, 10 (67%) were inguinal and 5 (33%), umbilical. Mean duration from CAPD start to onset of hernia was 31.4 months (range: 0~129 months). All inguinal hernia patients received standard McVay operation, 3 patients with umbilical hernia were repaired with primary herniorrhaphy and 1 patient with large fascial defect needed mesh implant. During mean follow-up periods of 31 months, recurrence was detected in 1 patient in umbilical hernia group. The only complication related to operation was wound hematoma in one patient. Two patients were converted to hemodialysis after operation because of low compliance to peritoneal dialysis in one patient and suspected catheter-related infection in the other. CONCLUSION: Our results indicate that hernia repair can be safely performed with acceptable outcomes in patients on CAPD.

Perianal diseases are the most common reasons for surgery in HIV-positive patients. This study aimed to evaluate the outcomes of these surgical procedures in Korean patients, focusing on wound healing and postoperative complications. Retrospective analysis was performed on 72 HIV-positive patients who underwent surgery by a single surgeon for benign anal disease between 1998 and 2011. Of these, 68.1% (49/72) of patients received surgery for condyloma acuminata, 19.4% (14/72) for anal fistulas, 6.9% (5/72) for hemorrhoids, and 5.6% (4/72) for perianal abscesses. Patients with condyloma acuminata received surgical excision with electrical coagulation, and all wounds healed completely within 3 months, though 16.3% (8/49) of these patients experienced recurrence. Twelve of the 49 patients (24.5%) who were treated for condyloma acuminata underwent simultaneous operations for concomitant anal fistulas (n = 6), hemorrhoids (n = 4), and perianal abscesses (n = 2). Overall, 3 postoperative complications developed following a total of 94 procedures, and there was no significant increase in complication rate for patients with a low CD4+ T-cell count ( < 200/microL) compared to those with a higher count. The results demonstrate favorable results following perianal surgery in HIV-positive Korean patients.

Although bidets are widely used in Korea, its effects on anorectal pressures have not been studied in detail in terms of the water settings used. Twenty healthy volunteers were placed on a toilet equipped with a bidet, and anorectal pressures were measured with a manometry catheter inserted into the rectum and anal canal before and after using the bidet at different water forces (40, 80, 160, 200 mN), temperatures (24degrees C vs 38degrees C), and water jet widths (narrow vs wide). The pressure at anal high pressure zone decreased from 96.1 +/- 22.5 to 81.9 +/- 23.3 mmHg at water jet pressure of 40 mN and 38degrees C wide water jet (P < 0.001), from 94.3 +/- 22.4 to 80.0 +/- 24.1 mmHg at water jet pressure of 80 mN and 38degrees C narrow water jet (P < 0.001), and from 92.3 +/- 22.4 to 79.6 +/- 24.7 mmHg at a water jet pressure of 80 mN and 38degrees C wide water jet (P < 0.001). At other settings, no significant changes were observed. Our results indicate that, in addition to cleansing effect, bidet could be used to reduce anal resting pressure in the same manner as the traditional warm sitz bath under the conditions of low or medium water jet pressure, a warm water temperature, and a wide type water jet.

PURPOSE: We performed this study to share experiences in the management of obturator hernia, which is a very rare disease among elderly women, because rarity of this disease will not approve an expert institute or surgeon and because the aging society, Korea, can increase the incidence. METHODS: Patient characteristics, clinical manifestations and treatment results were retrospectively collected from the 12 obturator hernia patients since 2000 in the three hospitals of the authors. Twenty-one obturator hernia cases reported in the Korean literatures were reviewed. In addition, we analyzed clinical features and treatment results of the total 33 patients, collectively. RESULTS: Most of the patients were elderly women except one young, poorly nourished, male patient with pulmonary tuberculosis. Their mean age was 79.6 years. Sixty-four percent (21/33) of the patients had preoperative morbidity. Symptoms from the compression of the obturator nerve, which is an important clue to the diagnosis, were observed in 67% (22/33). Interestingly, spontaneous or suspicious-spontaneous reductions were reported in 7 (21%) patients. Abdominal CT scan was the major tool for diagnosis. Abdominal approach alone could successfully manage most cases, though 84% (27/32) needed anastomosis of the bowel. Operative mortality was 2 of the 32 cases but morbidity was 44% of the 32 patients and the mean hospital period after operation was 21 days. CONCLUSION: Management of patients with obturator hernJd surgical management and proper peri-operative care as well as appropriate managing the families is essential for improved results.

PURPOSE: Parastomal hernia is a major complication of an intestinal stoma. This study was performed to compare the results of various operative methods to treat parastomal hernias. METHODS: Results of surgical treatment for parastomal hernias (postoperative recurrence, complications and postoperative hospital stays) were surveyed in 39 patients over an 11-year period. The patients enrolled in this study underwent surgery by a single surgeon to exclude surgeon bias. RESULTS: Seventeen patients were male, and twenty-two patients were female. The mean age was 65.9 years (range, 36 to 86 years). The stomas were 35 sigmoid-end-colostomies (90%), 2 loop-colostomies (5%), and 2 double-barrel-colostomies. Over half of the hernias developed within two years after initial formation. Stoma relocation was performed in 8 patients, suture repair in 14 patients and mesh repair in 17 patients. Seven patients had recurrence of the hernia, and ten patients suffered from complications. Postoperative complications and recurrence were more frequent in stoma relocation than in suture repair and mesh repair. Emergency operations were performed in four patients (10.3%) with higher incidence of complications but not with increased risk of recurrence. Excluding emergency operations, complications of relocations were not higher than those of mesh repairs. Postoperative hospital stays were shortest in mesh repair patients. CONCLUSION: In this study, mesh repair showed low recurrence and a low complication rate with shorter hospital stay than relocation methods, though these differences were not statistically significant. Further studies, including randomized trials, are necessary if more reliable data on the surgical treatment of parastomal hernias are to be obtained.

PURPOSE: Management strategy in acute appendicitis patients initially presenting with abscess or mass is surrounded with controversy. This study was performed to identify the outcomes of management for this condition. METHODS: We retrospectively analyzed prospectively registered 76 patients (male:female = 39:37; mean age, 50.8 years) with appendicitis presenting with abscess or mass over a 9-year period at the Seoul National University Hospital. Patients were divided into three groups (emergency operation group, delayed operation group, and follow-up group), and clinical characteristics and outcomes of treatment were investigated. RESULTS: Twenty-eight patients (36.8%) underwent an emergency operation. Of the remaining 48 patients, 20 (41.7%) were initially treated with conservative management through the use of antibiotics only; the other 28 (58.3%) with and additional ultrasound-guided percutaneous drainage of the abscess. Twenty-six (54.2%) patients underwent planned operations after conservative management, and 22 (45.8%) were followed without surgery (median duration, 37.8 month), of which 3 (13%) underwent an appendectomy due to recurrent appendicitis (mean of 56.7 days after initial attack). There were no statistical differences in types of operation performed (appendectomy or ileocecectomy), postoperative complications, and postoperative hospital stay among the patients who underwent emergency operations, delayed operations and operations for recurrence during follow-up. CONCLUSION: Although the recurrence rate was relatively low after conservative management for appendicitis patients presenting with abscess or mass, there was no difference in surgical outcome between the emergent, elective, or recurrent groups. Our results indicate that proper management of appendicitis with abscess or mass can be selected according to surgeon's preference.
