Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization–first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.

Purpose: Managing recurrent inguinal hernias is complex, and choosing the right surgical approach (laparoscopic vs. open) is vital for patient outcomes. This study compared the outcomes of using the same vs. different surgical approaches for initial and subsequent hernia repairs. Methods: We retrospectively analyzed patients who underwent recurrent inguinal hernia repair at Seoul National University Bundang Hospital between January 2014 and May 2023. Patients were divided into the “concordant” and “discordant” groups, comprising patients who underwent same and different approaches in both surgeries, respectively. Preoperative baseline characteristics, index surgery data, postoperative outcomes, and recurrence rates were analyzed and compared. Results: In total, 131 patients were enrolled; the concordant and discordant groups comprised 31 (open, n = 19; laparoscopic, n = 12) and 100 patients (open to laparoscopic, n = 68; laparoscopic to open, n = 32), respectively. No significant differences were observed in the mean operation time (50.5 ± 21.7 minutes vs. 50.2 ± 20.0 minutes, P = 0.979), complication rates (6.5% vs. 14.0%, P = 0.356), or 36-month cumulative recurrence rates (9.8% vs. 9.8%; P = 0.865). The mean postoperative hospital stay was significantly shorter in the discordant than in the concordant group (1.8 ± 0.7 vs. 1.4 ± 0.6, P = 0.003). Conclusion Most recurrent inguinal hernia repairs were performed using the discordant surgical approach. Overall, concordance in the surgical approach did not significantly affect postoperative outcomes. Therefore, the selection of the surgical approach based on the patient’s condition and surgeon’s preference may be advisable.

Purpose: This study aimed to evaluate the effect of prophylactic abdominal drainage (AD) in laparoscopic hemicolectomy, focusing on assessing postoperative pain outcomes. Methods: Patients were categorized into two groups: those with and without AD (AD group vs.no-AD group). A numerical rating scale (NRS) was used to assess postoperative pain on each postoperative day (POD). Further, the inverse probability of treatment weighting (IPTW) method was used to reduce intergroup bias. Results: In total, 204 patients who underwent laparoscopic hemicolectomies by a single surgeon between June 2013 and September 2022 at a single institution were retrospectively reviewed. After adjusting for IPTW, NRS scores on POD 2 were significantly lower in the no-AD group (3.2 ± 0.8 vs. 3.4 ± 0.8, p = 0.043). Further examination of postoperative outcomes showed no statistically significant differences in complications between the AD (17.3%) and no-AD (12.4%) groups (p = 0.170). The postoperative length of hospital stay was 7.3 ± 2.8 days in the AD group and 6.9 ± 3.0 days in the no-AD group, with no significant difference (p = 0.298). Time to first flatus was 3.0 ± 0.9 days in the AD group and 2.7 ± 0.9 days in the no-AD group, with no significant difference (p = 0.078). Regarding readmission within 1 month, there were four cases each in the AD (2.3%) and no-AD (1.7%) groups, with no significant difference (p = 0.733). Conclusion Laparoscopic hemicolectomy without AD resulted in no significant differences in postoperative clinical outcomes, except for postoperative pain. This finding suggests that prophylactic AD may exacerbate postoperative pain.

Background: Periorificial dermatitis (POD) is an acneiform or rosacea-like eruption that occurs in children and adults. Although POD is not rare, studies investigating its clinical characteristics and severity, particularly during childhood, have not been well conducted. Objective: This study aimed to investigate the clinical findings and severity of POD and the differences between childhood and adult POD. Methods: We retrospectively reviewed the medical records and clinical photographs of 131 patients diagnosed with POD in the Pusan National University Hospital and Pusan National University Yangsan Hospital over a 17-year period (2003∼2019). Results: Among 131 patients, 23 (17.6%) were children and 108 (82.4%) were adults. The mean age was 9.0 years (2.4∼17 years) and 43.9 years (19∼79 years), respectively. The male-to-female ratio was lower in adults with POD (1:2.6) than in children with POD (1:0.9). The involvement of the periocular area was more frequent in childhood POD (47.8%) than in adult POD (17.6%), although the involvement rates of the perinasal, perioral, and extrafacial areas were not different. When we checked the PeriOral Dermatitis Severity Index (PODSI), it was higher in adults (4.3±1.5) than in children (3.2±2.0). The clinical course according to age, sex, treatment, and severity did not differ between the groups. Conclusion Although the sample size of childhood POD was small, this study identified that the periocular area was more frequently involved and PODSI was lower in childhood POD than in adult POD.

Acanthosis nigricans (AN) is characterized by velvety hyperpigmented plaques, usually observed in skin folds. The different types of the condition include obesity-associated, syndromic, drug-induced, malignancy-related, and other types of AN. AN, an FGFR3 gene mutation-related disease, is associated with varying degrees of skeletal disorders. FGFR3 gene mutations are known to cause excessive inhibition of chondrocyte growth and keratinocyte proliferation, which is responsible for AN development. To our knowledge, only a small number of cases of AN with hypochondroplasia due to FGFR3 gene mutation (p.Lys650Thr) have been described in the literature. However, there are no reports of genetically confirmed AN with hypochondroplasia in Korea. Physicians should consider syndromic AN when symptoms develop at an early age or when associated skeletal anomalies are present.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin’s lymphoma accounting for approximately one-third of all cases. DLBCL can present as a lymph node or extranodal tumor. Cavernous sinus (CS) is a small but complex structure in which various arteries, sympathetic plexuses, and cranial nerves are passing through. Cavernous sinus syndrome (CSS) results from any disease process that affects CS including tumor, vascular disease, infection, or inflammation. Herein, we report a case of extranodal DLBCL diagnosed by skin biopsy presenting as CSS. A 58-year-old male presented with a 3-week-old, gradually growing subcutaneous nodule on the left upper lip. He also suffered from ptosis, ophthalmoplegia, diplopia, and headache confined to the right side for 3 months. Histopathologic examination of the left upper lip showed dense dermal infiltration of atypical large tumor cells resembling centroblasts and immunoblasts. Immunohistochemistry studies revealed that the tumor cells were positive for CD20, BCL2, BCL6, MUM1, and MYC. After additional radiologic evaluation with positron emission tomography-computed tomography (PET-CT), brain magnetic resonance imaging, and orbital CT, he was finally diagnosed with extranodal DLBCL involving the right CS, oculomotor muscles, and left upper lip.
