Lumbar hernias are rare posterolateral abdominal wall defects. There are two types of lumbar hernia. One is a superior lumbar hernia through the deep superior orifice (Grynfeltt triangle), and the other is a lower lumbar hernia through the superficial lower orifice (Petit triangle). A lumbar hernia is often misdiagnosed as a lipoma, so a cautious clinical examination is very important. Reports of recurrent lumbar hernia are extremely rare in the literature. We experienced a case of recurrence in an acquired primary lumbar hernia in a 71-year-old male who had undergone mesh-plug herniorrhaphy. The hernia orifice was 1 cm in diameter and exhibited a fibrous smooth margin. Hernia repair using 3-D mesh was performed. The patient had uncomplicated postoperative course and was discharged one day after the operation.

Lymphangiomas are rare congenital benign tumors arising from the lymphatic system, and are mostly encountered in the neck and axillary regions of pediatric patients (95%). Lymphangioma of the pancreas is extremely rare accounting for less than 1% of these tumors. We report here on a case of pancreatic cystic lymphangioma. A 54-year-old woman presented with intermittent postprandial abdominal discomfort and radiating back pain. Abdominal computed tomography scan revealed 8 x 6.5 cm hypodense cystic mass arising from the tail of the pancreas without septa or solid component. The initial impression was a pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenectomy. The histopathologic and immunohistochemical study helped make the diagnosis of a pancreatic cystic lymphangioma. Herein, we report a case of pancreatic cystic lymphangioma mimicking pancreatic pseudocyst and review the relevant medical literature.

PURPOSE: Laparoscopic surgery has become the mainstream surgical operation due to its stability and feasibility. Even for liver surgery, the laparoscopic approach has become an integral procedure. According to the recent international consensus meeting on laparoscopic liver surgery, laparoscopic left lateral sectionectomy (LLS) might be a new standard of care for left lateral surgical lesions. This study was designed to compare open LLS to laparoscopic LLS. METHODS: In total, 82 patients who had undergone LLS at Chonnam National University Hwasun Hospital between 2008 and 2015 were enrolled in this study. Among them, 59 patients underwent open LLS and 23 underwent laparoscopic LLS. These two groups were compared according to general characteristics and operative outcomes. RESULTS: The data analysis results showed that laparoscopic liver resection is superior to open liver resection in terms of the amount of bleeding during the operation and the duration of hospital stay. There was no statistical difference between the two groups in terms of operation time (p value=0.747). The amount of bleeding during the operation was 145.5±149.4 ml on average for the laparoscopic group and 320±243.8 ml on average for the open group (p value=0.005). The mean duration of hospital stay was 10.7±5.8 days for the laparoscopic surgery group and 12.2±5.1 days for the open surgery group (p value=0.003). CONCLUSION: This study showed that laparoscopic LLS is safe and feasible, because it involves less blood loss and a shorter hospital stay. For left lateral lesions, laparoscopic LLS might be the first option to be considered.

Primary angiosarcoma of the spleen is an extremely rare malignancy, the pathogenesis of which is not completely understood, with high metastatic potential and an exceedingly poor prognosis, regardless of treatment regimen. The major complication is splenic rupture, which often leads to fatal hemoperitoneum. Overall, since 1879 when Langerhans described the first case of angiosarcoma of the spleen, there have been approximately 200 cases reported in the literature. Moreover, to the best of our knowledge, spontaneous rupture of primary splenic angiosarcoma and spontaneous rupture of remnant or recurred angiosarcoma is extremely rare, and no cases were reported in English literature. We report a case of spontaneous splenic rupture due to angiosarcoma in a 68-year-old man, and also review the existing literature.

Myxoid liposarcoma of the spermatic cord (MLSC) is a rare variant of spermatic sarcoma. Typically, it presents during the sixth decade of life as a painless scrotal or inguinal mass. Although local recurrences are not uncommon, prognosis following complete tumor removal is good because metastases are rare. Although myxoid liposarcoma is common elsewhere in the body, less than 20 cases have been described in the spermatic cord. Distant metastasis with MLSC (e.g., bone, liver, lung) is extremely rare, and no cases have been reported in the English literature. We report one case of MLSC with multiple bone, liver and peritoneal metastasis, incidentally found during inguinal hernia repair.

PURPOSE: Incarcerated inguinal hernia may have very unusual hernial sac contents. In this study we aim to present clinical characteristics about incarcerated inguinal hernia of the greater omentum. METHODS: We retrospectively analyzed hospital records of 643 adult patients who underwent inguinal hernia repair from November 2001 to January 2009. The age, sex, location, type, symptom duration, body mass index (BMI), comorbidity, type of anesthesia, operative time, postoperative hospital stay and complications were reviewed. RESULTS: Of the 643 cases, 18 cases were omental incarcerated inguinal hernia group (O group). Seventeen in 18 cases of O group were male patient (NS). In O group, 16 cases were indirect type and 2 cases were femoral type (P=0.021). Mean age was younger in O group than in non-omental incarcerated inguinal hernia group (N group) (P=0.017). Duration of symptom was longer (P=0.013), and body mass index (BMI) was larger in O group (P=0.042). Operative time was longer in O group than in N group (P=0.006). CONCLUSION: The patients with omental incarcerated inguinal hernia mostly had long durations of protruding mass without pain. In these patients, operation was relatively difficult due to severe adhesion between the hernial sac and greater omentum. In addition, operative time took approximately 10 minutes longer. Therefore, general and spinal anesthesia is more feasible than local anesthesia.

Neurofibromatosis type 1 (NF1) is an autosomal dominant hereditary disorder. The pathogenesis of NF1 is suggested to be an alteration of the NF-1 gene, which normally functions as a tumor suppressor. A mutation of NF-1 causes the development of viable tumors in various sites. On the other hand, the synchronous manifestation of a gastrointestinal stromal tumor (GIST) and neuroendocrine tumor (NET) in the background of NF1 is extremely rare. This paper reports three cases treated with surgical intervention along with the long-term follow-up results. Three patients showed synchronous ampullary NET and GIST in association with NF1 supported by postoperative histopathologic analysis. Surgical treatments, such as pancreatoduodenectomy and local excision were applied. No recurrence occurred during the postoperative follow-up period of 10, 9, and 2.7 years. Synchronous GIST and NET in the background of NF1 is extremely rare, but the possible coexistence of other tumors in NF1 patients is relatively higher than that in the general population. Furthermore, both NETs and GISTs occurring in NF1 patients tend to be smaller in size compared to that in the general population. Therefore, when NF1 patients present with vague abdominal discomfort, close attention must be paid to identifying the coexistence of other neoplasms.
