Laparoscopic totally extraperitoneal hernia repair in patients with a history of previous abdominopelvic surgery.

A retrospective cohort study of patients undergoing laparoscopic inguinal hernia repair compared short- and long-term outcomes between individuals with or without history of previous abdominopelvic surgery, aiming to determine the feasibility of totally extraperitoneal (TEP) repair within this population. All patients who underwent elective TEP inguinal hernia repair by one consultant surgeon across three London hospitals from January 2017 to May 2023 were retrospectively analysed to assess perioperative outcomes. Two hundred sixty-two patients were identified, of whom two hundred forty-three (93%) underwent laparoscopic TEP repair. The most frequent complications were haematoma (6.2%) and seroma (4.1%). Recurrence occurred in four cases (1.6% of operations, 1.1% of hernias). One hundred eighty-four patients (76%) underwent day-case surgery. There were no mesh infections or explanations, vascular or visceral injuries, port-site hernias, damage to testicle, or persisting numbness. There were no requirements for blood transfusion, returns to theatre, or readmissions within 30 days. There was one conversion to open and one death within 60 days of surgery. Eighty-three (34%) had a history of previous AP surgery. There was no significant difference in perioperative outcomes between the AP and non-AP arms. This finding carried true for subgroup analysis of 44 patients whose AP surgical history did not include previous inguinal hernia repair and for those undergoing repair of recurrent hernia. In expert hands, laparoscopic TEP repair is associated with excellent outcomes and low rates of long-term complications, and thus should be considered as standard for patients regardless of a history of AP surgery.

Patches in Congenital Diaphragmatic Hernia: A systematic review.

OBJECTIVE: This systematic review aims to evaluate current choice in practice and outcomes of biomaterials used in patch repair of congenital diaphragmatic hernia (CDH). BACKGROUND: Multiple biomaterials, both novel and combinations of pre-existing materials are employed in patch repair of large size CDH. METHODS: Literature search was performed across Embase, Medline, Scopus, and Web of Science. Publications that explicitly reported patch repair, material used and recurrences following CDH repair were selected. RESULTS: Sixty-three papers were included, presenting data on 4598 patients of which 1811 (39.4%) were managed using 19 types of patches. Goretex® (GTX) (n=1259) was the most frequently employed patch followed by Surgisis® (n=164), Dualmesh® (n=114), Marlex®/GTX® (n=56), Tutoplast dura® (n=40), Dacron® (n=34), Dacron®/GTX® (n=32), Permacol® (n=24), Teflon® (n=24), Surgisis®/GTX® (n=15), Sauvage® Filamentous Fabric (n=13), Marlex® (n=9), Alloderm® (n=8), Silastic® (n=4), Collagen coated Vicryl® mesh (CCVM) (n=1), Mersilene® (n=1), and MatriStem® (n=1) Biomaterials were further subgrouped as: Synthetic non-resorbable (SNOR) (n=1458), Natural-resorbable (NR) (n=249), Combined natural and synthetic non-resorbable (NSNOR) (n=103), and Combined natural and synthetic resorbable (NSR) (n=1). Overall recurrence rate for patch repair was 16.8% (n=305). For patch types with n>20, recurrence rate was lowest in GTX/Marlex (3.6%), followed by Teflon (4.2%), Dacron (5.6%), GTX (13.8%), Permacol (16.0%), Tutoplast Dura (17.5%), Dualmesh (20.2%), SIS/GTX (26.7%), SIS (36.6%), and Dacron/GTX (37.5%).When analysed by biomaterial groups, recurrence was highest in NSR (100%), followed by NR (32.9%), NSNOR (17.5) and SNOR the least (14.0%). CONCLUSION: In this cohort, over one-third of CDH were closed using patches. To date, 19 patch types/variations have been employed for CDH closure. GTX is the most popular, employed in 70% of patients; however excluding smaller cohorts (n<20) GTX/Marlex is associated with the lowest recurrence rate (3.6%). SNOR was the material type least associated with recurrence while NSR experienced recurrence in every instance.

Surgical management of pediatric multiple magnet ingestions in the past two decades of minimal access surgery- systematic review of operative approaches.

BACKGROUND: Multiple magnet ingestion is increasingly reported in paediatrics and can cause significant morbidity. Various surgical approaches exist, though minimal literature compares outcomes between techniques. This review evaluates laparoscopic, laparoscopic-assisted, and open surgery with regard to outcomes. METHOD: Systematic review across MEDLINE, Embase, Scopus, and Web of Science identified reports of paediatric multiple magnet ingestion managed surgically between 2002 and 2022. RESULTS: Ninety-nine studies were included, reporting data from 136 cases. Of these, 82 (60%) underwent laparotomy, 43 (32%) laparoscopic surgery, and 11 (8%) laparoscopic-assisted procedures. Sixteen laparoscopic cases were converted to open, often due to intraoperative findings including necrosis/perforation, or grossly dilated bowel. Bowel perforation occurred in 108 (79%); 47 (35%) required bowel resection, and 3 had temporary stoma formation. Postoperative recovery was uneventful in 118 (86%). Complications were reported following 15 (18%) open and 3 (7%) laparoscopic surgeries. No complications occurred following laparoscopic-assisted surgery. All post-laparoscopic complications were Clavien-Dindo (CD) Grade I. Following open surgery, 5 complications were CD grade I, 6 were CD grade II, and 4 were CD grade IIIb, requiring re-laparotomy. Median length of stay for open and laparoscopic-assisted procedures was 7 days, and for laparoscopic was 5 days (p < 0.001). CONCLUSION: Surgical management of multiple magnet ingestion often achieved uncomplicated recovery and no long-term sequelae. Whilst open laparotomy was the more common approach, laparoscopic surgery was associated with reduced length of stay and postoperative complications. Therefore, in experienced hands, laparoscopic surgery should be considered first-line, with the possibility of conversion to open if required.
