  • About 20% of non-Hodgkin' lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer' ring. Malignant lymphoma arising in the parotid glands are relatively rare, although 90% of all salivary gland lymphomas, appear in parotid gland and are classified as extranodal non Hodgkin' lymphoma. We experienced one rare case of non-Hodgkin' lymphoma in the right parotid gland, with a painless swelling of the cheek region as the chief complaint. We treated with CHOP(cyclophosphamide, $750mg/m^2$ i.v. day1 ; doxorubicin, $50mg/m^2$ i.v. day 1 ; vincristine, $1.4mg/m^2$ i.v. day 1;prednisone, $50mg/m^2$ orally days 1 to 5. repeat every 21 days) and Rituximab combination therapy. We aimed to report here one case of non-Hodgkin' lymphoma in the right parotid gland with review of literature.

  • Purpose: The shape and location, the amount of the wound and the characteristics of the remaining tissues are known to influence wound contraction. The previous studies using small animals have not been an appropriate model because the wound healing mechanisms and skin structures are different from those of the human. The purpose of this study is to evaluate wound contraction according to the shape and location of the wound using a $Micropig^{(R)}$. Methods: Four $Micropigs^{(R)}$ (Medikinetics, Pyeongtaek, Korea) that were 10 months of age weighed 25 kg were used. Full thickness skin defects were made by clearing all the tissues above the fascial layer in the shape of square, a regular triangle and a circle of 9 $cm^2$ each on the back around the spine. Eight wounds were created on the back of each pig, 50 mm apart from each other. The randomly chosen wound shapes included 11 squares, 11 regular triangles, and 10 circles. Wound dressing was done every other day with polyurethane foam. The wound size was measured using a Visitrak $Digital^{(R)}$ (Smith & Nephew, Hull, UK) on every other day after surgery from day 2 to day 28. A biopsy was performed on day 3, and 1, 2, 3 and 4 weeks to investigate the degree of acute and chronic inflammation, the number of microvesssel and myofibroblast density using H & E stain and immunohistochemistry. The wound contraction rate was calculated to figure out the differences among each of the shapes and the locations. Results: The ultimate shape of the circle wound was oval, and that of the regular triangle and square were stellate. The maximum contraction rate was obtained on 8 to 10 days for all the shapes, which corresponds with the immunohistochemical finding that myofibroblast increases in the earlier 2 weeks whereas it decreases in the later 2 weeks. Epithelialization was seen in the wound margin on day 7 and afterwards. The final wound contraction rates were highest for the regular triangle shapes; however, there were no statistically significant differences. The wound contraction rates by locations showed statistically significant differences. The wound in the cephalic area presented more contractions than that of the wounds in the caudal area. Conclusion: The location of a wound is more important factor than the wound shape in wound contraction.

  • Background Surgical site infections (SSIs) result in significant patient morbidity following immediate tissue expander breast reconstruction (ITEBR). This study determined a single institution's 30-day SSI rate and benchmarked it against that among national institutions participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Methods Women who underwent ITEBR with/without acellular dermal matrix (ADM) were identified using the ACS-NSQIP database between 2005 and 2011. Patient characteristics associated with the 30-day SSI rate were determined, and differences in rates between our institution and the national database were assessed. Results 12,163 patients underwent ITEBR, including 263 at our institution. SSIs occurred in 416 (3.4%) patients nationwide excluding our institution, with lower rates observed at our institution (1.9%). Nationwide, SSIs were significantly more common in ITEBR patients with ADM (4.5%) compared to non-ADM patients (3.2%, P=0.005), and this trend was observed at our institution (2.1% vs. 1.6%, P=1.00). A multivariable analysis of all institutions identified age ${\geq}50$ years (odds ratio [OR], 1.4; confidence interval [CI], 1.1-1.7), body mass index ${\geq}30kg/m^2$ vs. < $25kg/m^2$ (OR, 3.4; CI, 2.6-4.5), and operative time >4.25 hours (OR, 1.9; CI, 1.5-2.4) as risk factors for SSIs. Our institutional SSI rate was lower than the nationwide rate (OR, 0.4; CI, 0.2-1.1), although this difference was not statistically significant (P=0.07). Conclusions The 30-day SSI rate at our institution in patients who underwent ITEBR was lower than the nation. SSIs occurred more frequently in procedures involving ADM both nationally and at our institution.

  • Background: Total shoulder arthroplasty (TSA) with a nonspherical humeral head component and inlay glenoid is a successful bone-preserving treatment for glenohumeral arthritis. This study aimed to describe the 90-day complication profile of TSA with this prosthesis and compare major and minor complication and readmission rates between inpatient- and outpatient-procedure patients. Methods: A retrospective review was performed of a consecutive cohort of patients undergoing TSA with a nonspherical humeral head and inlay glenoid in the inpatient and outpatient settings by a single surgeon between 2017 and 2022. Age, sex, body mass index, American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), and 90-day complication and readmission rates were compared between inpatient and outpatient groups. Results: One hundred eighteen TSAs in 111 patients were identified. Mean age was 64.9 years (range, 39-90) and 65% of patients were male. Ninety-four (80%) and 24 (20%) patients underwent outpatient and inpatient procedures, respectively. Four complications (3.4%) were recorded: axillary nerve stretch injury, isolated ipsilateral arm deep venous thrombosis (DVT), ipsilateral arm DVT with pulmonary embolism requiring readmission, and gastrointestinal bleed requiring readmission. There were no reoperations or other complications. Outpatients were younger with lower ASA and CCI scores than inpatients; however, there was no difference in complications (1/24 vs. 3/94, P=1.00) or readmissions (1/24 vs. 1/94, P=0.37) between these two groups. Conclusions: TSA with a nonspherical humeral head and inlay glenoid can be performed safely in both inpatient and outpatient settings. Rates of early complications and readmissions were low with no difference according to surgical setting. Level of evidence: IV.

  • A 45 year old male officer was admitted due to upper substernal pain for 1 month, which was aggravated by swallowing. On past and family history, there was no specific history except heavy drinking. Simple chest x-ray revealed no specific abnormal findings. Preoperative esophagofiberscopy and Barium study showed midesophageal diverticulum, pulsion type, at about 2 cm below the left main bronchus. The opening of the diverticulum was located at the left posterolateral aspect of esophagus. Midesophageal false diverticulum, measuring 2 x 2 x 1 .S cm in size, was noted at about 5 cm under the aortic arch protruding through a slit-like muscular defect. After inversion of diverticular sac, interrupted sutures with 3-0 silks were done on muscular defect site, and mediastinal pleura was reinforced on the lesion with interrupted sutures. On 4th postoperative day, esophagography revealed no diverticulum or stenosis. Also esophagofiberscopy showed smooth mucosal tag without disturbance of passage. On 14th postoperative day, the patient was discharged uneventfully, and follow-up for 3 months after discharge revealed nothing abnormal symptoms. The authors report one case of midesophageal, pulsion type, false diverticulum.

  • Purpose: Liver transplantation is a groundbreaking section in the field of surgery. Nowadays over 90% of success rate is accomplished and life expectancy of the patients has been elongated. Patients are now seeking for surgical procedures including cosmetic plastic surgery. But these patients take immunosuppressive medication and steroids, which can increase the risk of wound infection, and delay wound healing. By reviewing the case of a 21-year-old liver transplant recipient who underwent mastopexy due to breast ptosis, we discussed about the matters we should consider when performing surgery in liver transplantation recipients. Methods: The patient was a 21-year-old female who received liver transplantation from her father. She was exposed to massive amount of steroids and immunosuppressants, which led to breast ptosis. The vertical and short horizontal incision mastopexy using a medial-based pedicle was done, 29 months after the liver transplantation. Results: On postoperative day 1, she was discharged. On day 10, sutures were removed and taping was applied. There was no sign of wound infection, wound dehiscence, hematoma or bleeding. The patient was followed up at 3, 6 and 9 months after the operation. Mild recurrence of the glandular ptosis was observed but revision was not required. Conclusion: We were able to successfully operate without any complications in the liver transplant recipient. With special attention and consideration, cosmetic plastic surgery can be safely performed in organ transplantation recipients.

  • Symptomatic cerebral vasospasm (CVS) and delayed ischemic neurologic deficit (DIND) after unruptured aneurysm surgery are extremely rare. Its onset timing is variable, and its mechanisms are unclear. We report two cases of CVS with DIND after unruptured aneurysm surgery and review the literature regarding potential mechanisms. The first case is a 51-year-old woman with non-hemorrhagic vasospasm after unruptured left anterior communicating artery aneurysm surgery. She presented with delayed vasospasm on postoperative day 14. The second case is a 45-year-old woman who suffered from oculomotor nerve palsy caused by an unruptured posterior communicatig artery (PCoA) aneurysm. DIND with non-hemorrhagic vasospasm developed on postoperative day 12. To our knowledge, this is the first report of symptomatic CVS with oculomotor nerve palsy following unruptured PCoA aneurysm surgery. CVS with DIND after unruptured aneurysm surgery is very rare and can be triggered by multiple mechanisms, such as hemorrhage, mechanical stress to the arterial wall, or the trigemino-cerebrovascular system. For unruptured aneurysm surgery, although it is rare, careful observation and treatments can be needed for postoperative CVS with DIND.

  • Alterations in serum enzymes were studied in twenty-five patients who underwent open heart surgery in N.M.C. during the period from June 1979, to Feb. 1980. There were fifteen congenital and ten acquired heart diseases. In all patients, Rygg-Kyvsgaard five head roller pump and Polystan bubble oxygenator were used and serial determination of total level of Creatine phosphokinase [CPK], Lactic dehydrogenase [LDH], Glutamic oxaloacetic transaminase [SGOT] were made preoperatively, operation day [just after aortic clamp release, 2 hrs later, 4 hrs later, 6 hrs later], and postoperative days up to 5th day. Immediate postoperative clinical courses were also evaluated. Twenty-five patients were divided into two groups: Group A[13] was cardiopulmonary bypass time more than 95 minutes and aortic clamp time more than 45 minutes. Group B[12] was cardiopulmonary bypass time less than 95 minutes and aortic clamp time less than 45 minutes. The peak levels of SGOT, LDH in Group A were more significantly elevated than Group B [P<0.05]. But peak levels of CPK were not significant between two groups. In the view of clinical evaluation, poor clinical courses were more frequent in Group A [54%] than Group B[8%].

  • Although the incidence of esophageal atresia (EA) is higher in twins than in singletons by two to three times, EA usually affects only one member of twins. We report one pair of twins concordant for EA. A 31-year-old healthy woman bore monozygotic female twins at 36 weeks of gestation. They weighed 2,216 and 2,480 g, respectively. They had EA with distal tracheoesophageal fistula and underwent primary esophageal anastomosis on the birth day and the $2^{nd}$ day of life, respectively. Twin A also had suspicious antral obstruction and pyloroplasty was done simultaneously with esophageal repair. She needed antral web excision for continued gastric stasis one month after $1^{st}$ operation and three balloon dilatations of the esophagus. Twin B recovered uneventfully.

  • We present a case of a colonic involvement associated with necrotizing pancreatitis, with a review of the literature. A 10 year old boy had an appendectomy at the local clinic ten days ago. On admission, he complained nausea, vomiting and severe constipation. His abdomen was distended and he had tenderness on the left abdomen. Laboratory and radiologic studies revealed findings consistent with acute pancreatitis with colonic complication. He was treated conservatively for 30 days but did not improve. On hospital 30th day, abdominal pain developed and his vital sign changed. Abdominal CT suggested ischemic change of the transverse colon. At laparotomy, the left colon showed stenosis. The greatly distended transverse colon was resected and a transverse end colostomy was done. He was discharged at postoperative 45th day with improvement and colostomy closure was performed 8 months later.
