ABSTRACT

Purpose@#Rectal neuroendocrine tumors (NETs) <10 mm are endoscopically resected, while those ≥20 mm are treated with radical surgical resection. The choice of treatment for 10–20 mm sized rectal NETs remains controversial. This study aimed to verify factors predicting lymph node metastasis (LNM) of 10–20 mm sized rectal NET and utilize them to decide upon the treatment strategy. @*Methods@#Twenty-eight patients with 10–20 mm sized rectal NETs treated at Pusan National University Yangsan Hospital from January 2009 to September 2020 were divided into LNM (+) and LNM (–) groups, and their respective data were analyzed. @*Results@#Seven patients (25%) had LNM while 21 patients (75%) did not. Endorectal ultrasound findings showed tumor size was significantly larger in the LNM (+) than in the LNM (–) group (15 mm vs. 10 mm, P=0.018); however, pathologically, there was no significant difference in tumor size (13 mm vs. 11 mm, P=0.109). The mitotic count (P=0.011), Ki-67 index (P=0.008), and proportion of tumor grade 2 patients (5 cases, 71% vs. 1 case, 5%; P=0.001) were significantly higher in the LNM (+) group. In multivariate analysis, tumor grade 2 was the independent factor predicting LNM (odds ratio, 61.32; 95% confidence interval, 3.17–1,188.64; P=0.010). @*Conclusion@#Tumor grade 2 was the independent factor predicting LNM in 10–20 mm sized rectal NETs. Therefore, it could be considered as the meaningful factor in determining whether radical resection is necessary.

ABSTRACT

Synchronous quadruple colorectal cancer (CRC) is extremely rare without genetic alterations. We present a case of synchronous quadruple CRC with 2 lesions previously obscured by ischemic colitis. A 73-year-old woman was admitted to our emergency department. An abdominal computed tomography revealed ischemic colitis and irregular wall thickening of the sigmoid colon and sigmoid-descending junction, suspicious of 2 colon cancers. A colonoscopy examination revealed a fungating mass 20 cm from the anal verge, as well as ischemic colitis spanning the mucosa from the sigmoid colon to the transverse colon. The patient underwent laparoscopic Hartmann procedure. Pathologic examination confirmed both lesions as adenocarcinomas with microsatellite stable. Seven months postoperatively, instead of a laparoscopic Hartmann reversal, a laparoscopic total colectomy was performed due to the continued presence of severe ischemic colitis. The pathologic report suggested the presence of 2 distinct invasive adenocarcinomas in the descending colon without genetic alterations such as microsatellite instability.

ABSTRACT

An extragastrointestinal stromal tumor (EGIST) is a gastrointestinal stromal tumor that arises outside of the gastrointestinal tract. Most EGISTs are located in the omentum, mesentery, and retroperitoneum. The occurrence of an EGIST at the perianal region is very rare. Herein, we report our experience with EGISTs in the perianal area and review the literature. A 70-year-old man presented to our hospital with a 2-year history of anal discomfort. A pelvic magnetic resonance imaging scan showed a homogenous, well-defined, soft tissue density mass. The patient underwent mass excision, and the pathological examination confirmed that the mass was an EGIST. The size of the tumor was 4.3×3.2 cm, and the mitotic count was 1 per 50 high-power fields. The tumor cells were immunohistochemically positive for KIT and CD34 but were negative for S-100 and alpha-smooth muscle actin. There were no other abnormal findings in the gastrointestinal tract; upon pathological review, this case was confirmed as perianal EGIST. Therefore, EGIST should be considered as a differential diagnosis of perianal masses.

ABSTRACT

Genetic prion diseases account for about 10-15% of all cases of human prion disease and are caused by mutations in the prion protein gene. Gerstmann-Sträussler-Scheinker (GSS) disease is a rare genetic prion disease, which is characterized by slowly progressive cerebellar ataxia and the occurrence of cognitive decline in the later stage. P102L is the most common mutation in GSS. We report a patient with a P102L mutation that initially manifested as rapidly progressive dementia without cerebellar symptoms.

ABSTRACT

PURPOSE: We evaluated the relationship of cancer-associated fibroblasts (CAFs) and desmoplastic reactions with cancer invasiveness and long-term outcomes in patients with colorectal cancer (CRC). METHODS: Histologic evaluation of mature CAFs and desmoplasia was performed by observing the collagen fiber structure and fibroblast cytomorphology in the intratumoral stroma and invasive front of CRC tissues. Cancer-cell invasiveness was evaluated using lymphatic invasion, vascular invasion, perineural invasion, tumor budding, and tumor growth patterns. Overall survival and systemic recurrence were analyzed. A network analysis was performed between CAF maturation, desmoplastic reaction, and cancer invasiveness. RESULTS: The proportions of mature CAFs in the intratumoral stroma and the invasive front were 57.6% and 60.3%, respectively. Epidermal growth factor receptor (EGFR) overexpression was significantly higher in the mature CAFs in the invasive front as compared to immature CAFs. Lymphatic invasion increased as the number of mature fibroblasts in the intratumoral stroma increased. Tumor budding was observed in almost half of both mature and immature stroma samples and occurred more frequently in infiltrating tumors. On network analysis, well-connected islands were identified that was associated with EGFR overexpression, CAF maturation, and infiltrating tumor growth patterns leading to tumor budding. CONCLUSION: The maturity of CAFs and desmoplastic reactions were associated with cancer invasion. However, the cytomorphologic characteristics of CAFs were insufficient as an independent prognostic factor for patients with CRC.

ABSTRACT

OBJECTIVE: Postpancreatectomy hemorrhage (PPH) is an uncommon but serious complication of Whipple surgery. To evaluate the radiologic features associated with late PPH at the first postoperative follow up CT, before bleeding. MATERIALS AND METHODS: To evaluate the radiological features associated with late PPH at the first follow-up CT, two radiologists retrospectively reviewed the initial postoperative follow-up CT images of 151 patients, who had undergone Whipple surgery. Twenty patients showed PPH due to vascular problem or anastomotic ulcer. The research compared CT and clinical findings of 20 patients with late PPH and 131 patients without late PPH, including presence of suggestive feature of pancreatic fistula (presence of air at fluid along pancreaticojejunostomy [PJ]), abscess (fluid collection with an enhancing rim or gas), fluid along hepaticojejunostomy or PJ, the density of ascites, and the size of visible gastroduodenal artery (GDA) stump. RESULTS: CT findings including pancreatic fistula, abscess, and large GDA stump were associated with PPH on univariate analysis (p ≤ 0.009). On multivariate analysis, radiological features suggestive of a pancreatic fistula, abscess, and a GDA stump > 4.45 mm were associated with PPH (p ≤ 0.031). CONCLUSION: Early postoperative CT findings including GDA stump size larger than 4.45 mm, fluid collection with an enhancing rim or gas, and air at fluid along PJ, could predict late PPH.

ABSTRACT

PURPOSE: The aim of this study is to evaluate the safety and usefulness of indocyanine green (ICG) angiography in laparoscopic colorectal surgery and to explore its educational benefits in surgical beginners. METHODS: From July to October of 2015, a total of 21 patients with colorectal cancer underwent laparoscopic surgery using the fluorescence-guided imaging system, IMAGE1 S™ (Karl Storz, Germany). Real-time ICG fluorescence images and red inversion images were juxtaposed with standard white-light images for assessment of colonic perfusion. A surgical beginner group comprised of medical students (n=11) and surgical residents (n=11) were then questioned postoperatively about the colonic transection line and mesenteric vascular integrity across various image modes to determine the most proper view for surgical decision. RESULTS: A total of 21 patients underwent laparoscopic colorectal surgery using ICG angiography. Mean patient age was 69.7 years (52~77 years). Mean time-to-detection for the marginal arteries and colonic wall were 26.7 (range, 4~45) and 47.3 (range, 20~77) seconds, respectively. No injection-related adverse events were observed. Rate of change in the colonic transection line across modes was 59.9% (33.3~66.7%) in the surgical beginners. Decisions made by surgical beginners on the transection line were varied with the standard image, but converged to 81.8% in the ICG with red inversion mode. Surgical beginners preferred ICG with red inversion mode for assessment of mesenteric vascular integrity. CONCLUSION: ICG angiography seems to be safe and useful in evaluating colonic perfusion for transection decisions and could have educational benefits for surgical beginners in training to make surgical decisions.

ABSTRACT

Idiopathic portal hypertension (IPH) is a rare disorder which is clinically characterized by portal hypertension, splenomegaly, hypersplenism and the absence of liver cirrhosis. Patients with IPH have massive splenomegaly leading to increased portal venous flow and subsequent portal hypertension. In selected IPH patients with splenomegaly and hypersplenism, splenectomy can be regarded as an effective treatment protocol for decreasing portal hypertension. We report a case of a 44-year-old woman who was diagnosed with IPH accompanied by splenomegaly and hypersplenism. She underwent laparoscopic splenectomy and clinical symptoms and hypersplenism resolved. Our study shows that laparoscopic splenectomy can be considered as a procedure for treating patients with splenomegaly and hypersplenism due to IPH.

ABSTRACT

PURPOSE: The purposes of this study were to investigate the distribution of the visceral fat area (VFA) and general obesity and to compare visceral and general obesity as predictors of surgical outcomes of a colorectal cancer resection. METHODS: The prospectively collected data of 102 patients with preoperatively-diagnosed sigmoid colon or rectal cancer who had undergone a curative resection at Pusan National University Yangsan Hospital between April 2011 and September 2012 were reviewed retrospectively. Men with a VFA of >130 cm2 and women with a VFA of >90 cm2 were classified as obese (VFA-O, n = 22), and the remaining patients were classified as nonobese (VFA-NO, n = 80). RESULTS: No differences in morbidity, mortality, postoperative bowel recovery, and readmission rate after surgery were observed between the 2 groups. However, a significantly higher number of harvested lymph nodes was observed in the VFA-NO group compared with the VFA-O group (19.0 +/- 1.0 vs. 13.5 +/- 1.2, respectively, P = 0.001). CONCLUSION: Visceral obesity has no influence on intraoperative difficulties, postoperative complications, and postoperative recovery in patients with sigmoid colon or rectal cancer.

ABSTRACT

Hemangiomatosis of the skeletal system is a rare disease without specific symptoms and signs. We describe a 20-year-old patient with low back pain, whose plain radiographs of sacroiliac (SI) joint showed irregular sclerotic lesions. The patient was finally confirmed with skeletal hemangiomatosis by magnetic resonance imaging (MRI) and excisional biopsy of the lesion. The present case suggests that if patients with abnormal lesions of the SI joint in the plain radiographs do not have typical inflammatory back pain, advanced imaging is required to make an accurate diagnosis. Our case also emphasizes the importance of MRI and biopsy in establishing the diagnosis.

ABSTRACT

PURPOSE: The reflux of pancreatic enzymes into the biliary tract is associated with chronic inflammation and increases cellular proliferation of the biliary epithelium, leading to biliary carcinoma. The aim of this study is to detect the incidence of occult pancreaticobiliary reflux (OPBR) in patients who underwent elective cholecystectomy. METHODS: Forty-seven patients with symptomatic gallstones who underwent cholecystectomy were recruited for this study. The gallbladder bile samples were obtained from the specimen of gallbladder and the amylase level was measured. The immunohistochemistry of p53, SMAD4 and Ki-67 were performed for the detection of metaplasia and dysplasia. RESULTS: Biliary amylase was higher than the serum amylase in 10 patients (group A, 15,402.66 +/- 33,592.43 IU/L; group B, 13.06 +/- 18.12 IU/L). The mean age was 67.2 years in group A and 51.2 in group B (P < 0.01). The ratio of male to female was 1:2.3 and 1:1.8 in group A and B, respectively (P = 0.297). Eight patients in group A and thirteen patients in group B had inflammation (P = 0.014). The positive results of the Ki-67 test were exhibited in five cases in each group (P = 0.024). CONCLUSION: Results from the study indicate that the age was older, degree of inflammation and positive rate of Ki-67 were higher when OPBR was suspected. In conclusion, the patients with OPBR would need long-term follow-up, because the OPBR can cause dysplasia and the reflux of pancreatic juice may be considered as a risk factor for extrahepatic bile duct carcinoma.

ABSTRACT

We present a rare case of adult intussusception due to cecal lymphangioma. A 30-year-old female was admitted to our hospital with abdominal pain and a palpatable mass on the right lower quadrant. Preoperative radiologic studies by ultrasound and computed tomography showed ileocolic intussusception with a multiseptated cystic tumor as a leading point on the cecum. An ileocecectomy was performed, and the postoperative course was uneventful. Histopathology showed a cecal lymphangioma. Although endoscopic polypectomy or endoscopic mucosal resection is recommended for pedunculated or semi-pedunculated colonic lymphangiomas less than 2 cm in size, it is proper to treat large or symptomatic colonic lymphangiomas with limited a bowel resection or a tumor resection.

ABSTRACT

PURPOSE: Basosquamous carcinoma is a rare malignancy, with features of both basal cell carcinoma and squamous cell carcinoma. It is considered as aggressive tumor with a high risk of recurrence and metastases. Authors report a case of basosquamous cell carcinoma. METHODS: A 72 year-old man, who had an erythematous ulcer on his left auricle, described a slow growing lesion, starting at the posterior surface of the superior helix with a steady increase in size during the past 10 years. At operation, auricular cartilage was grossly invaded by the tumor and was, therefore, amputated with tumor-free margins. RESULTS: Histopathologic examination was revealed a basosquamous cell carcinoma. On positron emission tomography/computed tomography (PET/CT) and neck CT were negative for signs of further nodal involvement or metastases to other organs. At follow-up 6 months later, his wounds were noted to be well healed, with no evidence of local recurrence or identifiable metastases. CONCLUSION: Because basosquamous cell carcinoma has a significant potential to recur and metastasize, surgical excision for this type of carcinoma should be more extensive than that performed for conventional basal cell carcinoma or squamous cell carcinoma. In addition, regional lymph nodes should be monitored and close follow-up should be carried out.

ABSTRACT

PURPOSE: Schwannoma, a benign peripheral nerve tumor, is slow-growing, encapsulated neoplasm that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma occurring in the superficial radial nerve rare. This is a report of our experience with schwannoma arising from the superficial radial nerve with neurologic symptom. METHODS: A 55-year-old woman presented with eight-month history of progressive numbness and paresthesia in dorsum of the thumb and index finger. Physical examination revealed a localized mass on the midforearm. Sonographic examination showed an ovoid, heterogenous, hypoechoic lesion, located eccentrically in related to the superficial radial nerve. The lesion was mobile in the transverse but not in the longitudinal axis of the nerve, which was thought to favour schwannoma rather than neurofibroma. At operation, a 20 x 15 mm ovoid, yellowish grey mass was seen arising from the superficial radial nerve. The tumor present as eccentric masses over which the nerve fibers are splayed. Using operating microscope, the tumor was removed, preserving the surrounding nerve. RESULTS: Histology confirmed that the mass was a benign schwannoma. There were no postoperative complications. After two months the patient had no clinically demonstrable sensory deficit. CONCLUSION: An unsusual case of a schwannoma of the superficial radial nerve is presented. In case with neurologic symptom, prompt surgical decompression must be made to prevent further nerve damage and to restore nerve function early.

ABSTRACT

PURPOSE: Blue toe syndrome consists of blue or purplish toes in the absence of a history of obvious trauma, serious cold exposure, or disorders producing generalized cyanosis. It is a life-threatening and still underrecognized disease. It can be commonly occurred by vascular surgery, invasive cutaneous procedures or anticoagulant therapy. Our case is presented of blue toe syndrome related to atheromatous embolization that was presumably triggered by angio CT. METHODS: A 69-year-old man presented with the suddenly developed pain, cyanosis and livedo reticularis of the toes in right foot. Dorsalis pedis pulses were palpable. He had been performed a diagnostic angio CT 1 month earlier. Angio CT revealed diffuse aortic atheromatous plaque in lower abdominal aorta and both common iliac artery. One month after angio CT, he visited our clinic. There was no visible distal first dorsal metatarsal artery and digital artery of right first toe in lower extremity arteriography. A diagnosis was established of blue toe syndrome. Because his symptom was aggravated, we performed the exploration of the right foot. After exposure of first dorsal metatarsal artery, microsurgical atheroembolectomy was done. RESULTS: There were no postoperative complications. After three months the patient had no clinically demonstrable problems. CONCLUSION: Patient with blue toe syndrome is at high risk of limb loss and mortality despite treatment. Blue toe syndrome produces painful, cyanosed toes with preserved pedal pulses. It needs to be aware of blue toe syndrome. Careful history should reveal the diagnosis. Treatment is controversial, however, most believe that anticoagulation therapy should be avoided.

ABSTRACT

Both heterotaxia and intraluminal duodenal diverticulum (IDD) are uncommon congenital anomalies. Heterotaxia is a group of situs anomalies and IDD is a type of duodenal atresia. Heterotaxia is commonly associated with intraabdominal abnormalities causing intestinal obstruction, but heterotaxia with IDD is extremely rare. Herein we report a case of 21-year-old female who presented with symptoms of duodenal obstruction due to IDD associated with heterotaxia. This is the second case found as a result of a search through PubMed. We first used 3-dimentional virtual computed tomograph endoscopy for making the diagnosis and the treatment plan of this patient.

ABSTRACT

PURPOSE: Ganglion cysts of peripheral nerve are uncommon. Ganglion cysts located within the nerve and extraneural ganglia that cause symptomatic nerve compression have been reported. We report an unusual case of epineural ganglion cyst confined to the epineurium of the sural nerve at the foot. METHODS: A 45-year-old woman was referred because of a mass on the foot. She had six months' history of pain and numbness in the right small toe. During the examination of the lesion, multinodular cystic mass was identified arising from the epineurium of the sural nerve. The nerve fascicles were compressed by the cyst, but the cyst wall clearly did not invade the fascicle. With the aid of surgical microscope, the epineural cyst was completely excised along with epineural tissue to which it was attached, and the sural nerve was decompressed. There was no relationship between the cyst and either the joint capsule or tendon sheath. Since the cyst was on the periphery of the nerve it was possible to remove the cyst intact without damaging the underlying fascicles. RESULTS: The postoperative course was uneventful. Pathologic examination showed a ganglion cyst with a degenerated collagen fibers and contained a yellowish, jelly-like mucinous substance. No neural elements were identified within the cystic wall. Her sensory impairment improved progressively. At the 15 months follow-up, she was asymptomatic with no neurological deficits. CONCLUSION: Rarely, ganglion cysts can involve peripheral nerves, leading to varing degrees of neurological deficits. Intraneural intrafascicular ganglion may be difficult to separate from the neural elements without nerve injury. Epineural ganglion, subcategorized as intraneural extrafascicular ganglion, can be removed without damage to the underlying nerve.
