Purpose:
We devised omental free-shaped flap reinforcement on anastomosis and dissected area (OFFROAD) following reconstruction after gastrectomy. This study aimed to evaluate its safety and early clinical outcomes.
Methods:
One hundred fifty-six patients who underwent totally laparoscopic distal gastrectomy with delta anastomosis from July 2016 to April 2018 were divided into the OFFROAD group (80 patients) and non-OFFROAD group (76 patients). Differences in short-term operative outcomes and surgical complications were compared between the groups. All patients’ inflammatory marker levels were measured to monitor flap necrotic change and inflammatory reactions. The clinical features of both groups in terms of anastomotic leakage were transcribed.
Results:
Pain score in postoperative day1 was significantly lower in OFFROAD group. The serum WBC count on POD 1 was significantly lower in OG than in NOG. The mean duration of OFFROAD was shorter than five minutes. There were no statistical differences in short-term outcomes and surgical complications between two groups. Anastomotic leakage occurred in three patients in each group and there was no statistical difference in incidence. However, clinical features were notable when anastomotic leakage occurs. Unlike all three patients of non-OFFROAD group manifested every features of peritonitis, each patient of OFFROAD group just manifested only one of the three.
Conclusion
This study showed the safety and feasibility of OFFROAD procedure. It might mitigate septic complications when there is an anastomotic leakage. Additional large-scale study is needed to assess the versatile usefulness of OFFROAD aside from its role as a physical barrier.

PURPOSE: In general, sinusitis in children is diagnosed by clinical symptom and paranasal sinus x-ray. Sinus plain x-rays in children is simple, inexpensive, and speedy. However, it requires proper interpretative techniques, because different development of each sinus, soft tissues overlying sinuses and bony structure require precise diagnosis. This study was conducted to compare plain x-rays with OMU CT scans. METHODS: From September 1996 through August 1997, thirty nine patients who were diagnosed as sinusitis based on clinical symptoms and plain x-rays at the pediatric department of Seoul Adventist Hospital were studied. Water's view, Caldwell's view and lateral view were taken for the plain x-rays with concurrent OMU CT scans prior to treatments. RESULTS: Ten cases (25.6%) out of 39 patients showed posterior nasal drip and fourteen cases (35.9%) showed nasal obstruction. Twelve cases (30.8%) were related to allergic diseases and seven cases (58.3%) among these 12 cases were bronchial asthma. Sensitivity of plain x-ray were 88.5+/-12.9% for maxillary sinuses, and 59.9+/-13.65% for ethmoidal sinuses. CONCLUSION: When maxillary sinusitis is suspected, plain X-ray for maxillary sinuses is enough to diagnose sinusitis, but for ethmoidal sinuses it may be underestimated or overestimated in comparison with OMU CT scan. Ethmoidal sinusitis requires careful diagnosis and follow-up because it plays important roll for chronic sinusitis due to its structure. Therefore, we recommends OMU CT scan to diagnose paranasal sinusitis of children with plain X-ray.

The operation for esophageal cancer is both complex and challenging, and may be associated with significant morbidity and mortality compared to other oncologic surgeries. Minimally invasive surgeries have been applied on various kinds of surgery to enhance better recovery with minimal surgical complications. But for the esophageal cancer, it has not been actively applied yet. With improvement in instrumentations and increasing experience with endoscopic surgical techniques, minimally invasive surgical approaches to esophageal cancer are being explored to determine feasibility, results and potential advantages. We experienced eight cases of minimally invasive surgery for esophageal cancer and report here focusing on surgical techniques and tips.

Paradoxical vocal fold movement (PVFM) is an uncommon upper airway disorder defined as paradoxical adduction of the vocal folds during inspiration. The etiology and treatment of PVFM are unclear. The physician should manage this condition because of the possibility of near complete airway obstruction in severe case of PVFM. We report a case of successful airway management in a patient with PVFM by applying continuous positive airway pressure (CPAP). In this case, PVFM was detected after removing an endotracheal tube from a 67-year-old male who underwent excision of a laryngeal mass. The patient recovered without complications in 1 day with support by CPAP.

Benign metastasizing leiomyoma (BML) is a rare entity, characterized by the occurrence of multiple smooth muscle nodules in the lung with histologically benign leiomyoma. Both the uterine and pulmonary tumors have been found to express estrogen and progesterone receptors, which suggest that the pulmonary lesions represented metastases from leiomyoma. We experienced a 41-year-old female patient with BML and report here with the literature review.

BACKGROUND: Epidermal growth factor receptor (EGFR) inhibitors are associated with cutaneous adverse events, including papulopustular eruption, xerosis, paronychia, hair abnormality and mucositis. In particular, acneiform eruptions might serve as the visible markers of anti-tumor activity and the therapeutic efficacy of EGFR inhibitors. OBJECTIVE: Our aims are to investigate the common cutaneous adverse events induced by cetuximab, which is one of the EGFR inhibitors approved by the US Food and Drug Administration, and to analyze whether the presence and severity of papulopustular eruptions have a correlation with the tumor response. METHODS: We retrospectively reviewed the medical records and clinical photographs of 114 Korean patients who had been treated with cetuximab at Asan Medical Center from September 2004 to March 2007. Results: Papulopustular eruptions occurred in 100 patients (87.7%) and this usually happened 10 days after starting chemotherapy. There was a tendency that the better the tumor responded to the chemotherapeutic agents including cetuximab, the more severe were the papulopustular eruptions. The papulopustular eruptions prominently improved after the treatment with topical agents such as benzoyl peroxide, metronidazole, clindamycin and retinoid, and with systemic agents such as minocycline and tetracycline, and there was no adverse event induced by this treatment for papulopustular eruptions. Xerosis appeared in 67 patients (58.8%), and there was a tendency that the more severe papulopustular eruptions were, the more frequently xerosis occurred. Paronychia occurred in 8 patients (7.0%). CONCLUSION: Although the cutaneous adverse events are burdensome to the patients, they might serve as visible markers of the anti-tumor activity and therapeutic efficacy of cetuximab and they can be easily and safely controlled with many topical and systemic agents. Therefore, it is important for dermatologists to properly treat these cutaneous adverse events and to reassure the patient to continue with the cetuximab treatment.

We sought to determine whether early amniocentesis is a safe and acceptable method of genetic evaluation in early pregnancy. During the 20-month period from February 1994 to September 1995, 80 consecutive early amniocentesis were performed transabdominally at 12(+3)-14(+6) weeks of gestation and 305 consecutive mid-second-trimester transabdominal amniocenteses were performed at 16(+0)-18(+0) weeks of gestation. All amniotic fluid samples were cultured using flask method. There were no significant differences between the early and mid-second-trimester amniocenteses in failed sampling, ambiguous results, pregnancy loss within 4 weeks after the procedure, pregnancy loss from 4 weeks after procedure to 28 weeks of gestation, preterm birth, and perinatal death. We may conclude that early amniocentesis is a safe and acceptable method for prenatal diagnosis.

BACKGROUND: Early diagnosis of tuberculosis is critical, especially in Korea, an area where tuberculosis is endemic. Because antibody responses to some membrane proteins of Mycobacterium tuberculosis are not comparable, and the policy of BCG vaccination and the prevalence of tuberculosis are different from country to country, the usefulness of the serological diagnostic tests is questionable in Korea, even though they have been confirmed to be useful in other countries. In the specific context of Korea, we tried to evaluate the validity of the ICT Tuberculosis Test (ICT), a membrane-based antibody kit that purports to detect the 5 M. tuberculosis complex-specific antigens including 38-kDa protein. METHOD: 68 patients with tuberculosis were tested: 37 had no history of previous tuberculosis, and 31 were reactivated cases. The control group comprised 77 subjects: 25 healthy adults, 35 hospital workers with frequent contact with tuberculosis patients, and 17 in-patients with non-tuberculous respiratory diseases. RESULTS: The diagnostic sensitivities of the ICT were 87% and 73% in patients with versus without previous history of tuberculosis, respectively. The sensitivities of smear-positive and smear-negative patient groups were 81% and 73%, respectively. Both of the two patients with extrapulmonary tuberculosis tested positive through the ICT. The specificities of the ICT were 88%, 94%, and 94% in healthy adults, hospital workers, and non-tuberculous patients, respectively, with an overall specificity of 92%. Conclusion: It is suggested that when combined with traditional techniques, the ICT is an useful tool for the diagnosis of pulmonary tuberculosis. The procedure is simple, easy to perform, rapid, and needs no equipment. It shows 73% sensitivity and 92% specificity for the diagnosis of tuberculosis.
