Efficacy of Transversus Abdominis Plane Block and Rectus Sheath Block in Laparoscopic Inguinal Hernia Surgery

We aimed to assess the efficacy of transversus abdominis plane (TAP) block and rectus sheath (RS) block in patients undergoing laparoscopic inguinal hernia surgery. Few studies have addressed the efficacy and safety associated with TAP block and RS block for laparoscopic surgery. Thirty-two patients underwent laparoscopic inguinal hernia surgery, either with TAP and RS block (Block⁺ group, n = 18) or without peripheral nerve block (Block⁻ group, n = 14). Preoperatively, TAP and RS block were performed through ultrasound guidance. We evaluated postoperative pain control and patient outcomes. The mean postoperative hospital stays were 1.56 days (Block+ group) and 2.07 days (Block⁻ group; range, 1–3 days in both groups; P = 0.0038). A total of 11 patients and 1 patient underwent day surgery in the Block⁺ and Block⁻ groups, respectively (P = 0.0012). Good postoperative pain control was more commonly observed in the Block⁺ group than in the Block⁻ group (P = 0.011). TAP and RS block was effective in reducing postoperative pain and was associated with a fast recovery in patients undergoing laparoscopic inguinal hernia surgery.Key words: TAP block, RS block, Inguinal hernia, Laparoscopic surgeryInguinal hernia repair is one of the most frequently performed surgical operations. The debate regarding the best repair technique for inguinal hernia is ongoing. Several trials have compared the efficacy of the Lichtenstein and laparoscopic approach for inguinal hernia repair.^1–6 Laparoscopic repair of inguinal hernia has certain advantages over open repair, such as reduced postoperative pain and morbidity, early recovery, rapid return to work, and better quality of life.^3–7 Several strategies have been reported to ameliorate postoperative pain in laparoscopic surgery.⁸The transversus abdominis plane (TAP) block is a regional anesthetic technique that provides analgesia to the parietal peritoneum as well as to the skin and muscles of the anterior abdominal wall.^9,10 Despite a relatively low risk of complications and a high success rate using modern techniques, TAP block remains overwhelmingly underused. Although the technique is technically straightforward, it has not been adopted in clinical practice.^9,11 Moreover, rectus sheath (RS) block has been reported to be effective for pain management in patients undergoing umbilical hernia repair surgery.¹²Generally, in laparoscopic inguinal hernia surgery, the sites of port incision are on the umbilical and bilateral middle abdomen. Those sites are associated with considerable postoperative discomfort. Thus, we performed TAP and RS block to ameliorate postoperative pain and improve patient outcomes. Here, we aimed to assess the efficacy of TAP and RS block in patients undergoing laparoscopic inguinal hernia surgery.     

A case of bleeding duodenal ulcer with pemphigus vulgaris during steroid therapy

We report a rare case of bleeding duodenal ulceration in the different form of pemphigus vulgaris (PV). A 52-year-old female was diagnosed with acute pharyngitis and administered methylprednisolone. After several days, melena and many blisters were noted on her body. Endoscopy revealed blood oozing from the second part of a duodeneal ulcer around the major duodenal papilla. After initial endoscopic hemostasis, we observed a large regional, shallow duodenal ulcer. The blisters were suspected to represent the Nikolsky’s sign. The histological findings of her skin were characterized by suprabasal acantholysis and mixed inflammatory cell infiltrates, including scattered eosinophils. There were no other significant findings on skin biopsy or by direct immunofluorescence. Enzyme-linked immunosorbent assay showed an elevated titer of anti-desmoglein 3 autoantibodies in her serum, and the patient was finally diagnosed with mucosal-dominant PV. Although we performed multiple biopsies from the esophagus, stomach and duodenum, the samples did not contain significant findings to enable us to distinguish from pemphigus vulgaris. Corticosteroids remain an essential component of PV treatment. When clinicians encounter PV development during steroid therapy, upper gastrointestinal complications should be considered and diagnostic endoscopy conducted.     

A Prospective Analysis of Efficacy and Long-Term Outcome of Radiation Therapy for Gastric Mucosa-Associated Lymphoid Tissue Lymphoma

Background/Aims: Few studies exist on the efficacy and long-term outcome of radiation therapy (RT) for gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: Twenty-two patients with stage I or stage II(1) disease were prospectively evaluated, including 14 patients without Helicobacter pylori(H. pylori) infection and 8 patients with persistent lymphoma after H. pylori eradication. RT dose was 30 Gy in daily fractions of 1.5 Gy. All patients underwent endoscopic and histological follow-up regularly. Results: The study included 22 patients with a mean age of 63 years. The t(11;18)(q21;q21) translocation occurred in 8 of the 22 cases. All patients showed complete remission without any serious toxicity. At a median follow-up evaluation 74 months (range 27-159) after completion of RT, the overall and relapse-free survival rates after 5 years were 91 and 84%, respectively. Although no patient showed local recurrence of lymphoma, distant recurrence was detected in 3 patients, all of whom were H. pylori negative; MALT lymphoma relapsed in two patients with the t(11;18)(q21;q21) translocation, and diffuse large-cell lymphoma developed in one patient without the translocation. Conclusion: RT provides excellent local control of the gastric MALT lymphoma. However, continuous follow-up is mandatory as relapse may occur in other sites.     

A multi-centered epidemiological study evaluating the reliability of the treatment difficulty indices developed by the Japan Prosthodontic Society

BackgroundThe diagnostic assessment of the level of difficulty in treating patients who need prosthodontic care is useful to establish a medico-economically efficient system with primary care dentists and prosthodontic specialists.Materials and methodsA multi-axis assessment protocol was established using the newly established treatment difficulty indices. The protocol contains Axis I: oral physiological conditions (e.g., teeth damage and/or missing teeth); Axis II: general health and sociological conditions (e.g., medical disorders); Axis III: oral health-related quality of life (OHRQOL; e.g., oral health impact profile: OHIP); and Axis IV: psychological health (e.g., mood, anxiety, somatoform disorders). A preliminary study on the test–retest consistency of the protocol was conducted to check the levels of reliability of the indices prior to a large-scale, multi-center cohort study on the validity of the protocol.ResultsThe test–retest consistency in terms of the oral physiological condition (Axis I) after data reduction was 0.63 for patients with teeth problems, 0.95 for partially edentulous patients, and 0.62 for edentulous patients. The reliability for general health and sociological conditions (Axis II), OHRQOL (Axis III), and psychological health (Axis IV) were 0.88, 0.74, and 0.61, respectively. These values reflect either “sufficient agreement” or “excellent agreement” in accordance with the criteria established by Landis and Koch (1977) [1].ConclusionThis protocol is the first multi-axis assessment scheme introduced for prosthodontic treatment with sufficient reliability. This new system is therefore expected to have a significant impact on future dental diagnostic nomenclature systems.     

Conservative treatment for adolescent idiopathic scoliosis: can it reduce the incidence of surgical treatment?

Since 1986, the authors have been conducting conservative treatment for idiopathic scoliosis with the combination of brace treatment and physical treatment (side shift exercise and hitch exercise). A total of 328 female patients with adolescent idiopathic scoliosis who were at least 10 years of age at the first visit, with Cobb angle of 10° at the minimum and followed until after 15 years of age or skeletal maturity were included. The average Cobb angle was 32.4° and the average age was 13.8 years at the first visit. Surgery was recommended when curvature progressed to >50°. Twenty of 328 patients (6.1%) with more severe curves to begin with (mean Cobb angle at admission of 48.5?±?9.3°) progressed to 62.2?±?8.5° and were treated with spinal fusion by the age of 16.0?±?2.6 years. The remaining 308 patients, of comparable age at inception of treatment but with a smaller original mean Cobb angle (32.4?±?11.1°), showed no significant increase in magnitude of curvature (mean 33.6?±?11.5°) by the time of discharge (18.6?±?3.1 years). The fact that curvature magnitude was maintained at <35° means that these patients will have a good prognosis for avoiding dramatic progression during adulthood.
