PURPOSE: This study compared the patency of the splenic vessels between laparoscopic and open spleen and splenic vessel-preserving distal pancreatectomy. METHODS: We retrospectively reviewed a database of 137 patients who underwent laparoscopic (n = 91) or open (n = 46) spleen and splenic vessel-preserving distal pancreatectomy at a single institute from 2001 through 2015. Splenic vessel patency was assessed by abdominal computed tomography and classified into three grades according to the degree of stenosis. RESULTS: The splenic artery patency rate was similar in both groups (97.8 vs. 95.7%, P = 0.779). Also, the splenic vein patency rate was not significantly different between the 2 groups (74.7% vs. 82.6%, P = 0.521). Postoperative wound complication was significantly lower in the laparoscopic group (19.8% vs. 28.3%, P = 0.006), and hospital stay was significantly shorter in the laparoscopic group (7 days vs. 9 days, P = 0.001) than in the open group. Median follow-up periods were 22 months (3.7–96.2 months) and 31.7 months (4–104 months) in the laparoscopic and open groups, respectively. CONCLUSION: Laparoscopic distal pancreatectomy showed good splenic vessel patency as well as open distal pancreatectomy. For this reason, splenic vessel patency is not an obstacle in performing laparoscopic splenic vessel-preserving distal pancreatectomy.

PURPOSE: It is believed that blood from the superior mesenteric vein and splenic vein mixes incompletely in the portal vein and maintains a streamline flow influencing its anatomic distribution. Although several experimental studies have demonstrated the existence of streamlining, clinical studies have shown conflicting results. We investigated whether streamlining of portal vein affects the lobar distribution of colorectal liver metastases and estimated its impact on survival. METHODS: Data of patients who underwent hepatectomy for colorectal liver metastases were retrospectively collected. The chi-square test was used for analyzing the distribution of metastasis. Cox analysis was used to identify risk factors of survival. Fisher exact test was used for subgroup analysis comparing hepatic recurrence. RESULTS: A total of 410 patients were included. The right-to-left ratio of liver metastases were 2.20:1 in right-sided colon cancer and 1.39:1 in left-sided cancer (P = 0.017). Cox analyses showed that margin < 5 mm (P < 0.001; 95% confidence interval [CI], 1.648–4.884; hazard ratio [HR], 2.837), age ≥ 60 years (P = 0.004; 95% CI, 1.269–3.641; HR, 2.149), N2 status (P < 0.001, 95% CI, 1.598–4.215; HR, 2.595), tumor size ≥ 45 mm (P = 0.014; 95% CI, 1.159–3.758; HR, 2.087) and other metastasis (P = 0.012; 95% CI, 1.250–5.927; HR, 2.722) were risk factors of survival. However, in 70 patients who underwent right hemihepatectomy for solitary metastasis, left-sided colorectal cancer was a risk factor (P = 0.019; 95% CI, 1.293–17.956; HR, 4.818), and was associated with higher recurrence than right-sided cancer (43.1% and 15.8%, respectively, P = 0.049). CONCLUSION: This study showed significant difference in lobar distribution of liver metastases between right colon cancer and left colorecral cancer. Furthermore, survival of left-sided colorectal cancer was poorer than that of right-sided cancer in patients who underwent right hemihepatectomy for solitary metastasis. These findings can be helpful for clinicians planning treatment strategy.

Bronchobiliary fistula (BBF) is a rare complication of radiofrequency ablation (RFA), in which there is abnormal communications between the biliary tract and the bronchial trees. Surgery should only be considered for BBF when non-invasive interventions have failed. In this report, we describe the surgical management for BBF when complicated by an abscess that was encountered after RFA in a 52-year-old woman with recurrent hepatocellular carcinoma (HCC). She had previously undergone central bisectionectomy of HCC 7 years ago, and had been treated with a sixth transarterial chemoembolization and first RFA for recurrent HCC after the operation. After the liver abscess and BBF occurred in the posterior section of the liver, she received posterior sectionectomy and hepaticojejunostomy, drainage of the lung abscess, diaphragmatic resection and repair because it was impossible to drain the abscess radiologically. Symptomatic improvements were being achieved through operative treatments where pleural effusion and pneumonic consolidation was obliterated on a 2-months follow-up image.

The spontaneous regression of herniated cervical discs is not a well established phenomenon. However, we encountered the 3 cases of spontaneous regression of severe radiculopathic herniated cervical discs that were treated using a non-surgical method. Each of the patients were treated with a combination of manipulation, dry needling and analgesics. In each case, the symptoms improved within 12 months of treatment and magnetic resonance imaging (MRI) conducted at that time revealed marked regression of the herniated disc in all cases. These cases provide additional examples of spontaneous regression of herniated cervical discs documented by MRI following non-surgical treatment.

A right-sided aortic arch and Kommerell's diverticulum, remnants of the left dorsal aortic arch in the circulation of the embryo, are uncommon congenital defects of the aorta. They may be asymptomatic in most cases, but symptoms are manifested by compressing mediastinal structures or are related to congenital heart anomalies. If aneurismal dilatation of the diverticulum presents with rupture, it is lethal. We report a case of esophageal compression by a right-sided aortic arch and Kommerell's diverticulum that mimicked an esophageal submucosal tumor in a patient who complained of symptoms during the past ten years of food retention in the upper thorax when a bolus of food was ingested.

PURPOSE: Botulinum toxin (BTX) acts by inhibiting acetylcholine (ACh) release at the presynaptic cholinergic neuromuscular junction, and is applied in various urethral and bladder dysfunctions, including detrusor external sphincter dyssynergia (DESD). We investigated the use of BTX in DESD patients as a reversible chemical sphincterotomy. MATERIALS AND METHODS: A total of 6 patients (male 3, female 3) with DESD were included. Their mean age was 45.5 years. The underlying diseases were multiple sclerosis (1), meningomyelocele (1), spinal cord injury (1), multiple systemic atrophy (1) and transverse myelitis (2). All the patients had severe voiding symptoms and large residual urine, despite anticholinergics and alpha-adrenoceptor antagonists with clean intermittent catheterization (CIC). Urodynamic studies were performed before and 1 month after treatment. A total of 100 units of BTX-A (Botox(R)) were injected at 4 sites, 3, 6, 9 and 12 o'clock relative to the external sphincter, under anesthesia, on an outpatient basis. The alpha-adrenoceptor antagonist medication was discontinued for evaluation after surgery. RESULTS: At 1 month after the injection, the mean maximal flow rate was increased (from 8.4 to 12.2ml/sec) and mean residual urine was decreased (from 258 to 120ml) compared to the baseline values. The external sphincter pressure was decreased. All patients were able to discontinue the CIC. There were no systemic complications, such as respiratory distress or myasthenic crisis. CONCLUSIONS: Transurethral BTX-A injections were safe and effective for releasing or ameliorating a lower urinary tract obstruction due to DESD, and a safe and valuable therapeutic option in DESD patients not desiring surgery or CIC, and who are resistant to medications.

PURPOSE: To evaluate the long-term efficacy of laparoscopic Burch colposuspension, we reviewed the success rate and subjective satisfaction rate of this operation for female patients with stress incontinence. Materials and Methods: Between Sep. 1995 and Aug. 1999, 126 patients underwent laparoscopic Burch colposuspension. We reviewed 88 patients who had been followed up for more than 3 years. The mean patient age was 51.1 years and 26 of the 88 patients complained of urge incontinence. All were preoperatively assessed with voiding cystourethrography (VCUG), urodynamic study, cystoscopy and stress, emptying, anatomic, protection, and instability (SEAPI) score. Colposuspension was performed with 2 non- absorbable sutures (n=70) or polyprophylene mesh and Tacker (n=18) by the retroperitoneal approach. RESULTS: At the mean follow-up of 56 months, 58 patients (66%) were cured, and 19 patients (22%) showed significant improvements. Sixty one (94.4%) out of 66 patients who had previously required pad protection attained a pad-free status. Urge incontinence disappeared in 15 out of 26 patients, but 8 (9.1%) patients complained of de novo urge incontinence. The pre- operative factors (age, symptom periods, symptom score, abdominal leak point pressure (ALPP) and VCUG findings) made no difference for the success rate. The subjective satisfaction rate was 93%. The mean operation time was 88 minutes and it decreased to 67 minutes after 50 cases. The mean hospital stay was 3.5 days and mean duration of catheterization was 3.7 days. We had 5 (5.68%) cases of complications: two port site bleeding, one peritoneal injury, one respiratory acidosis and one obturator venous bleeding. However, all of them eventually recovered. CONCLUSIONS: Laparoscopic colposuspension revealed good results on the long-term follow-up, as well the operation as being a minimally invasive procedure. There was a 88% success rate, a 93% subjective satisfaction rate and 94% of the patients became pad free.

This study was carried out to determine the seropositivity for Orientia tsutsugamushi infection among wild rodents captured in farms and mountains of Korea. A total 965 wild rodents of 7 species and 48 Crocidura laciura were captured in farms and mountains of 6 province during 1997~2000 in Korea. Serological evidence for O. tsutsugamushi infection was obtained using O. tsutsugamushi antigens by indirect immunofluorescent antibody technique (IFA). Four hundred eighty four Apodemus agrariusus, 246 Apodemus peninsulae, 179 Eothenomys regulus, 44 Microtus fortis, 6 Micromys minutus, 5 Mus musculus, and 1 Cricetula triton were captured in Gyeonggi, Gangwon, Chungnam, Gyeongbuk, Gyeongnam, and Jeonbuk province. Among them, 59 (12.2%) A. agrariusus, 22 (8.9%) A. peninsulae, 12 (6.7%) E. regulus, 5 (11.4%) M. fortis and 1 (16.7%) M. minutus were IF antibody positive against O. tsutsugamushi Gilliam or Karp strain.

To investigate the seroprevalence of the Orientia tsutsugamushi infection of Apodemus peninsulae and genomic variations in O. tsutsugamushi isolates, 246 A. peninsulae were trapped in 14 mountainous areas approximately 500 meter above sea level in Korea during the period of 1997 and 2000. Seropositive rate of O. tsutsugamushi among A. peninsulae was 31.8% in Kyunggi, 8.2% in Chunbuk and 7.1% in Kangwon provinces by microimmunofluorescent test. The 56 kDa protein gene was amplified by PCR in the spleens of seropositive A. peninsulae. Two amplicons from seropositive A. peninsulae were sequenced and their phylogeny was analysed on the basis of sequence homology. The 56 kDa genes of A. peninsulae 98-12 strain and A. peninsulae 98-16 strain showed 98.7% nucleotide homology and 96.6% amino acid similarity. A. peninsulae 98-12 and A. peninsulae 98-16 strain were related to Kuroki, Boryong and Karp strains showing 93.3~92.2%, and 87.1~84.6% homologies in nucleotide and amino acids levels, respectively. In the phylogenetic analysis, A. peninsulae 98-12 and A. peninsulae 98-16 strain formed a distinct group with Boryong, Kuroki and Nishino strains and were clearly distinguished from other genetic groups. The results suggest that A. peninsulae might be an important reservoir of O. tsutsugamushi in Korea.
