A 69-year old man presented with severe epigastric pain for 1 day. He had early gastric cancer at the antrum and underwent a distal subtotal gastrectomy and Billorth II gastrojejunostomy one month later without any post-operative complications. Radiologic examination revealed a large amount of retroperitoneal free air formation. Because of unremitting pain and unstable vital sign, exploratory laparotomy was followed. During the operation, a perforated duodenal diverticulum at the posterior wall of the 2nd portion of the duodenum was identified. He underwent diverticulectomy and primary closure. He was discharged on the 18th post operative day and has been followed up without any evidence of comlpication for several months.

It has been standard practice in many institutions to use a combination of a light general anesthesia and an epidural block for lower abdominal and pelvic surgery. This combination of a balanced anesthesia can provide various benefits to the patient such as less bleeding in the surgical field, the use of a lower concentration of general anesthetics, less muscle relaxant, and post operative pain management. However, there are several problems associated with hemodynamics such as bradycardia and hypotension etc. In order to block the pain of the high surgical area with a lumbar epidural puncture postoperatively, a large volume of local anesthetic is required and consequently an extensive blockade of sympathetic, sensory and motor functions can occur causing motor weakness, numbness and postural hypotension. Therefore, the patient is unable to have early ambulation postoperatively. In this study, thoracic epidural catheterization was undertaken to locate the tip of the catheter exactly at the surgical level for upper abdominal surgery, and was followed by general anesthesia. Twenty-one patients scheduled for upper abdominal surgery were selected. Fifteen of them had hepatobiliary operations and the remaining 6 had gastrectomies. Thoracic epidural punctures were performed mostly at T9-T10 (57.1%) and T8-T9. Neuromuscular blocking agents were not used in half of the cases and the, mean doses of relaxant were $3.5{\pm}1.0mg$ in gastrectomies, and $2.7{\pm}0.9mg$ in cases of hepatobiliary operation. Epidural morphine was injected 1 hour before the end of the operation for postoperative pain control. Eight patients did not require additional analgesics and the mean dose of epidural morphine was $2.2{\pm}0.9mg$, and 13 cases were given 0.125% epidural bupivacaine when patients complained of pain. Their initial doses of epidural morphine were $1.9{\pm}0.4mg$ and the mean duration of bupivacaine was 6 hours 20 minutes${\pm}40$ minutes. In conclusion. thoracic epidural analgesia is valuable to reduce postoperative pain in patients with upper abdominal surgery, However, it is not easy to maintain this balanced anesthesia with high epidural analgesia-and light general anesthesia for upper abdominal surgery because of marked hemodynamic changes. Therefore, further practice will be required.

The reduction of the postoperative wound pain has been a concern in recent surgery, especially in various types of minimally-invasive surgeries. This study was performed to evaluate the postoperative analgesic effect of the preincisional local anesthesia with the mixture of ketorolac(Tarasyn) and bupivacaine to the surgical site in minimally-invasive thyroid surgeries. Of 491 patients who were scheduled for minimally-invasive thyroid surgeries between October 1999 and July 2000, 244 were randomly assigned to receive a mixture of ketorolac tromethamine 15mg(0.5ml) and 0.25% bupivacaine 3ml via surgical site infiltration 3 minutes prior to the skin incision. The outcomes of these patients were compared to those of the 247 controls. Total number of patients in need of post-operative analgesic requirements(n=39, 16.0%), total dose of postoperative analgesics used($19.6{\pm}8.4mg$ of ketorolac) and Visual Analogue Pain Score(VAS, $2.6{\pm}1.2$) of the preincisional local anesthesia group were significantly lower than those of the control group(p<0.05). The mean postoperative hospital stay was $1.6{\pm}0.4$ days for the preincisional local anesthesia group versus $1.9{\pm}0.7$ days for the control group. The preincisional local infiltration of ketorolac and bupivacaine in the minimally invasive thyroidectomies reduces postoperative wound pain thus would be more beneficial to the patients.

Objective : The purpose of the present study is to assess the long-term results of microsurgical dorsal root entry zonotomy (MDT) for the treatment of medically intractable upper-extremity spasticity. Methods : The records of nine adult patients who underwent MDT by one operating neurosurgeon from March 1999 to June 2004 were retrospectively reviewed by another investigator who had no role in the management of these patients. In all patients, MDT was performed on all roots of the upper limb (from C5 to T1) for spasticity of the upper extremity. The degree of spasticity was measured by the Modified Ashworth Scale (grade 0-4). Severity of the pain level was determined using the Numeric Rating Scale (NRS, score 0-10). Also, patient satisfaction of the post-operative outcome was assessed. Results : Comparing the preoperative and postoperative spasticity using the Modified Ashworth Scale, we observed improvement in all patients, particularly in five of the nine patients (55.6%) who improved by three grades over an average of 66.4 months (range, 40-96). Regarding patient satisfaction, seven patients (77.8%) had affirmative results. None of the patients experienced severe, life-threatening, postoperative complications. We observed a decrease in the intensity of painful spasms to less than three scores as measured by NRS in all four patients with associated pain. Conclusion : This study shows that MDT provides significant, long-term reduction of harmful spasticity and associated pain in the upper limbs.

Conventional surgical therapy for oral soft tissue includes the use of scalpel, diathermy, cryotherapy and electrosurgery. But, these therapies have some surgical problems. Nowadays, laser surgery can be considered as the another option for conventional surgical therapy. Compared to conventional surgical therapies, advantages of laser therapy include maintenance of sterile conditions, promotion of wound healing, reduction of bleeding, less instruments, post operative pain reduction, less scar, saving cost by using fewer materials, staff and time. Carbon dioxide ($CO_2$) laser uses gaseous medium, and has long wavelength about 10,600nm. The first advantage of $CO_2$ laser for surgical treatment of oral soft tissue is hemostasis and visibility improvement by making relatively dry field. These case reports are about cases of minor surgery of oral soft tissue using $CO_2$ laser, and emphasize advantages of laser compared to conventional surgical therapies.

Purpose: The purpose of this study was to examine the sensation changes in upper extremity and the quality of life for post-operative mastectomy patients. Methods: This study used a descriptive study design. The participants were 132 women who had mastectomies after being diagnosed with breast cancer and were participating in breast cancer self-help groups. The sensation changes in the arm of the surgery site was measured by the arm symptoms which were subjective uncomfortable feelings of the affected arm, and the quality of life was measured by Medical Outcomes Study Short Form-36. Collected data were analyzed by ANOVA, t-test, ${\chi}^2$-test and multiple regression with SPSS WIN 12.0 program. Results: Patients with stage IV breast cancer had severe changes in sensation of the arm. Participants with lymphedema had statistically significant changes in sensation compared to participants without lymphedema, but the quality of life was not different between the two groups. Pain by the SF 36 was statistically different between the two groups, with- and without-lymphedema. The factors in upper extremity's sensation changes which influence on quality of life were pain and heaviness. Conclusion: Nursing intervention for relieving pain and heaviness of the affected arm needs to be developed in order to improve QOL of the breast cancer survivors.

We evaluated the need for prophylactic postoperative oral antibiotic medication in extraction of asymptomatic impacted mandibular third molars. All patient didn't show sign of pain, inflammation, swelling and trismus at the time of extraction. In the experimental group, oral antibiotic medication(Amoxicillin) was carried out for 5 days postoperatively. In the control group, the patients received no antibiotic medication. All groups didn't use antibiotic irrigation solution. Rule of group composition randomized. The surgical technique was the same in all cases. Parameters that were evaluated were infection, pain, facial swelling, trismus. We could not find any significant difference between the experimental and control groups.(P<0.05) The results of our study show that post operative oral prophylactic antibiotic medication after the extraction of impacted mandibular third molars does not contribute to less infection, pain, facial swelling and increased mouth opening after surgery. Therefore we suggest that prophylactic postoperative oral antibiotic medication is not needed in extraction of asymptomatic impacted mandibular third molars.

Background: We have previously found that intra-peritoneal lidocaine instillation before pneumoperitoneum attenuates pneumoperitoneum-induced hypertension. Whether this procedure alters patient's hemodynamic status during operation should be determined for clinical application. This study elucidated the possible mechanism of the attenuation of the pneumoperitoneum-induced hypertension by intra-peritoneal lidocaine before pneumoperitoneum. Methods: Thirty-four patients underwent laparoscopic cholecystectomy (LC) were randomly allocated into two groups. After induction of general anesthesia, 200 mL of 0.2% lidocaine (lidocaine group, n=17), or normal saline (control group, n=17) were sub-diaphragmatically instilled 10 minutes before pneumoperitoneum. The changes in systolic blood pressure, heart rate, central venous pressure, stroke volume, cardiac output, and systemic vascular resistance were compared between the groups. The number of analgesics used during post-operative 24 h was compared. Results: Systolic blood pressure was elevated during pneumoperitoneum in both groups (p<0.01), but the degree of elevation was significantly reduced in the lidocaine group than in the control (p<0.01). However, stroke volume and cardiac output were decreased and systemic vascular resistance was increased after induction of pneumoperitoneum (p<0.05) without statistical difference between two groups. The number of analgesics used was significantly reduced in the lidocaine group (p<0.01). Conclusion: These data suggest that intra-peritoneal lidocaine before pneumoperitoneum does not alter patient's hemodynamics, and attenuation of pneumoperitoneum-induced hypertension may be the consequence of reduced intra-abdominal pain rather than the decrease of cardiac output during pneumoperitoneum. Therefore, intra-peritoneal lidocaine instillation before pneumoperitoneum is a useful method to manage an intraoperative pneumoperitoneum-induced hypertension and to control postoperative pain without severe detrimental hemodynamic effects.

Backgrounds/Aims: Hemangiomas are the most common benign liver lesions; however, they are usually asymptomatic and seldom require surgery. Enucleation and resection are the most commonly performed surgical procedures for symptomatic lesions. This study aims to compare the outcomes of these two surgical techniques. Methods: A retrospective analysis of symptomatic hepatic hemangiomas (HH) operated upon between 2000 and 2021. Patients were categorized into the enucleation and resection groups. Demographic profile, intraoperative bleeding, and morbidity (Clavien-Dindo Grade) were compared. Independent t-test and chi-square tests were used for continuous and categorical variables respectively. p-value of < 0.05 was considered significant. Results: Sixteen symptomatic HH patients aged 30 to 66 years underwent surgery (enucleation = 8, resection = 8) and majority were females (n = 10 [62.5%]). Fifteen patients presented with abdominal pain, and one patient had an interval increase in the size of the lesion from 9 to 12 cm. The size of hemangiomas varied from 6 to 23 cm. The median blood loss (enucleation: 350 vs. resection: 600 mL), operative time (enucleation: 5.8 vs. resection: 7.5 hours), and postoperative hospital stay (enucleation: 6.5 vs. resection: 11 days) were greater in the resection group (statistically insignificant). In the resection group, morbidity was significantly higher (62.6% vs. 12.5%, p = 0.05), including one mortality. All patients remained asymptomatic during the follow-up. Conclusions: Enucleation was simpler with less morbidity as compared to resection in our series. However, considering the small number of patients, further studies are needed with comparable groups to confirm the superiority of enucleation over resection.

Lumbar Sympathectomy is a surgery for plantar hyperhidrosis, vascular and other reflex sympathetic diseases and has a various indications and physiologic effects. However it is not performed actively compared to thoracic sympathectomy because of its invasiveness. Therefore, we tried to perform lumbar sympathectomy using mediastinoscopy with small incision and introduce this new surgical technique. Material and Method: From July 2003 to December 2004, 18 patients undewent lumbar sympathectomy with mediastinoscopy at Inje University Sanggye Paik Hospital. There were 12 males and 6 females whose mean age was 24.3$\pm$8.2 years ranging from 18 to 67 30 cases of lumbar sympathectomy was performed with mediastinoscopy of which 24 cases were for plantar hyperhidrosis and 6 cases for other diseases. Result: Mean operation time was 37.2$\pm$12.5 minutes and mean post operation hospital stay was 3.1$\pm$2.2 days. There was one post sympathetic neuralgia and one peritoneal opening. Conclusion: Lumbar sympathectomy using mediastinoscopy is a simple and effective technique and has the advantage of cosmetics, post operative pain and hospital stay. However, further studies with large number of cases should be carried out for better outcome.
