Comparison of Perioperative Complication Rates of Total Extraperitoneal and Transabdominal Preperitoneal Repairs in Primary Inguinal Hernia.

Background: Hernia may be defined as a protrusion of viscus through layers anatomically designed to contain that viscus. Most abdominal hernias occur at well-described sites of potential weakness. Repair of inguinal hernia is one of the most common operations in general surgery. Objectives: To compare the perioperative complication rates of total extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repairs of primary inguinal hernias. Materials and Methods: It is a randomised comparative study, conducted at the department of general surgery. A total of 50 patients were included and divided into two groups with 25 in each. Group A represents the laparoscopic TEP repair and group B represents the laparoscopic TAPP repair. Patients above 18 years with primary unilateral inguinal hernia were included. Patients having complicated inguinal hernia and history of previous abdominal surgery were excluded. Results: We observed that hernia occurrence is more common in the 31-50 years of age group and right-sided hernia is more common. Scrotal oedema and conversion to open surgery chances are similar in both TEP and TAPP groups. The duration of surgery in TEP is significantly higher as compared to TAPP. Patients who underwent TEP experienced less pain as compared to TAPP as per visual analogue scale. Postoperative hospital stay and time taken to resume the routine activity were significantly less in case of TEP. Conclusion: TEP is preferred over TAPP for laparoscopic hernia repair because it preserves the peritoneal integrity and has lesser postoperative pain. The early recovery and return to the routine work were seen with the patient treated with the TEP and also showed better visual analogue score than the TAPP repair group.

The success rate of interphase fluorescence in situ hybridization in plasma cell disorders can be improved using unconventional sources of plasma cells.

BACKGROUND: Immunomagnetic cell sorting (IMCS) is a preferred technique for the enrichment of plasma cells (PC) before fluorescence in situ hybridization (FISH). Here, we share our real-world experience regarding the success rate of IMCS, its limitations, and the utility of alternate sources to obtain a successful FISH in various PC disorders. MATERIALS AND METHODS: A retrospective analysis was performed in patients with a PC neoplasm, who underwent bone marrow (BM) examination, and FISH testing over 30 months. In all cases with an unsuccessful IMCS, an attempt was made to identify the cause of failure. RESULTS: Immunomagnetic cell sorting of PCs was successful in 395/450 cases (87.8%; 77/98 cases (78.6%) with <10% PCs and 318/352 (90.3%) with ≥10% PCs in BM aspirate; P = .003). Among cases with unsuccessful IMCS (<10% PCs; n = 21 and ≥10% PCs; n = 34), an alternate source could be used successfully in 34 (62%) patients and includes air-dried trephine biopsy imprint smears (n = 28) with aggregates or sheets of PCs, fine-needle aspiration smears/biopsy from plasmacytoma (n = 5), and ascitic fluid (n = 1). 284/395 (71.9%) patients with successful IMCS and all 34 cases with an alternate source of PCs showed at least one cytogenetic abnormality on four-probe FISH. CONCLUSION: Variations in the sample quality together with significant variation in the number of PCs between BM aspirate and the trephine biopsy imprint smears/biopsy reduce the success rate of IMCS in a real-world scenario and necessitate utilization of patient-specific alternate sources of PCs like a trephine biopsy imprint or cytology smears from extramedullary sources for successful FISH testing in PC neoplasms.
