A comparative study of negative suction drainage in inguinal hernia operations at Saraswathi Institute of Medical Sciences, Pilkhua, Hapur Uttar Pradesh

Background: The inguinal area is the weakest region of the abdominal wall. So, this is the most common site for the development of hernias. Inguinal hernias are the commonest amongst all the hernias and hernia repair is the most frequently done operation worldwide. There is no agreement among surgeons regarding the need for drains. Some use sparingly and some use it routinely. This study aims to evaluate the use of negative suction drain in inguinal hernia surgery.Methods: We studied sixty patients of inguinal hernias both direct and indirect for one year and followed up for next 1-2 years. This prospective study aimed to see the effect of negative suction drainage in hernia surgery.Results: Both the groups did well postoperatively. It was beneficial to put a negative suction drain in those patients who had a bigger hernia, fatty patients with the thick fatty lower abdominal wall and older patients.Conclusion: It is advisable to put a negative suction drain in inguinal hernia surgery and strongly advocated if the dissection had been difficult, old patients and fatty lower abdominal wall

The usage of drainage after primary total hip or knee arthroplasty: best evidence selection and risk of bias considerations

Background Numerous systematic reviews investigating the benefit of the usage of drainage after primary total hip or knee arthroplasty have been published with divergent conclusions. We aim to determine the best available evidence and consider risk of bias of these articles and to provide recommendations. Methods A systematic search of systematic reviews published through to May 2020 was performed in MEDLINE, EMBASE and Cochrane library. Methodological quality, risk of bias and best evidence choice of included articles were evaluated by AMSTAR instrument, ROBIS tool and Jadad decision algorithm, respectively. We selected systematic reviews with high methodological quality and low risk of bias ultimately as best evidence. Results Twelve meta-analyses were included lastly. According to the ROBIS tool, seven of the included systematic reviews were with low risk of bias and five with high risk of bias. The Jadad decision algorithm suggested that two reviews conducted by Zan et al. for hip and Si et al. et al. for knee were selected as the best evidence, with highest AMSTAR score and low risk of bias. Conclusions Ten systematic reviews were included as low-quality with only two high-quality studies. Based on the current available evidence, we have insufficient confidence to draw conclusion that whether to use closed suction drainage for both total knee and hip arthroplasty. To verify the necessity and benefit of using closed suction drainage after primary total knee and hip arthroplasty, and develop exact recommendations, further studies are still required.

The role of suction drainage in the management of peri-operative bleeding in Total and Unicomcompartmental knee arthroplasty: a retrospective comparative study

Background Suction drainage is commonly applied after total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) to reduce hematoma, swelling and to favor surgical wound healing. However, its efficacy remains controversial; thus, the purpose of this study is to evaluate drainage efficiency in the management of postoperative bleeding in TKA and UKA. Methods The cohort comprised 134 clinical records of patients affected by knee osteoarthritis (OA) who underwent either TKA or UKA. All the patients were subdivided into 2 groups: the first one with drainage and the second one without drainage (respectively 61 and 73 patients). For each group, hemoglobin levels in the preoperative, first, second and third postoperative day were collected. Postoperative complications such as swelling, bleeding from the surgical wound or the need for blood transfusion, were also recorded. Results Our results did not show any significant difference of hemoglobin levels in the first (p = 0.715), second (p = 0.203) and third post-operative day (p = 0.467) between the two groups. Moreover, no significant correlation between knee swelling or transfusion rate and the drainage was observed (p = 0.703 and p = 0.662 respectively). Besides, a significant correlation was found between bleeding from the surgical wound and the absence of drainage (p = 0.006). Conclusions The study demonstrates how the routine use of suction drainage does not provide substantial benefits in the postoperative blood loss management after TKA or UKA.

External Negative Pressure Drainage of the Pancreatic Duct in Pancreatogastrostomy Following Pylorus-Preserving Pancreaticoduodenectomy—Feasibility and Technique

Background: Postoperative pancreatic fistula (POPF) is a major cause of morbidity after pancreaticoduodenectomy. There is no consensus on the best technique to protect the pancreato-enteric anastomosis and reduce the rate of POPF. This study investigated the feasibility and efficiency of external suction drainage of the pancreatic duct to improve the healing of pancreaticogastrostomy.Methods: Between July 2019 and June 2021, 21 consecutive patients undergoing elective pancreaticoduodenectomy were included. In all patients we performed a pancreaticogastrostomy and inserted a negative pressure drainage into the pancreatic duct. The length and diameter of the pancreatic duct were measured and the texture of the pancreas was evaluated. The daily secretion volume and the lipase value via pancreatic duct drainage were documented. The occurrence of POPF was evaluated.Results: None of the patients had drainage-related complications. In 4 patients we registered a dislocation of the drainage from the pancreas duct into the stomach. 17/21 Patients showed no signs of POPF. A biochemical leak was measured in one patient. Furthermore, 2 patients had a POPF grade B. In one patient, POPF grade C required reoperation and resection of the remnant pancreas. All 4 cases of POPF met the risk criteria soft pancreas, high volume and high lipase value in the duct drainage.Conclusion: The insertion of the pancreatic duct drainage was feasible and caused no drainage-related morbidity. POPF-rate was moderate in the risk population of soft pancreas and small duct.

Vacuum-Assisted Suction Drainage as a Successful Treatment Option for Postoperative Symptomatic Lymphoceles

Purpose Lymphoceles often occur within several weeks or even months after surgery. Mostly asymptomatic and therefore undiagnosed, they may be self-healing without any treatment. A small percentage of postoperative lymphoceles are symptomatic with significant pain, infection, or compression of vital structures, thus requiring intervention. Many different treatment options are described in the literature, like drainage with or without sclerotherapy, embolization of lymph vessels, and surgical approaches with laparoscopy or laparotomy. Inspired by reports stating that postoperative suction drainage can prevent the formation of lymphoceles, we developed a simple protocol for vacuum-assisted drainage of symptomatic lymphoceles, which proved to be successful and which we would therefore like to present. Materials and Method Between 2008 and 2020, 35 patients with symptomatic postoperative lymphoceles were treated with vacuum-assisted suction drainage (in total 39 lymphoceles). The surgery that caused lymphocele formation had been performed between 8 and 572 days before. All lymphoceles were diagnosed based on biochemical and cytologic findings in aspirated fluid. The clinical and imaging data were collected and retrospectively analyzed. Results In total, 43 suction drainage catheters were inserted under CT guidance. The technical success rate was 100 %. One patient died of severe preexisting pulmonary embolism, sepsis, and poor conditions (non-procedure-related death). In 94.8 % of symptomatic lymphoceles, healing and total disappearance could be achieved. 4 lymphoceles had a relapse or dislocation of the drainage catheter and needed a second drainage procedure. Two lymphoceles needed further surgery. The complication rate of the procedure was 4.6 % (2/43, minor complications). The median indwelling time of a suction drainage catheter was 8–9 days (range: 1–30 days). Conclusion The positive effects of negative pressure therapy in local wound therapy have been investigated for a long time. These positive effects also seem to have an impact on suction drainage of symptomatic lymphoceles with a high cure rate. Key Points: Citation Format

Excessive Blood Loss After Revision Hip Arthroplasty is Related to the use of Closed Suction Drainage: A Prospective Randomized Study

Background:Suction drainage after primary total hip arthroplasties (THA) offers no benefits. Revision hip arthroplasties (RHA) are more demanding procedures and associated with greater blood loss compared to primary cases. There is still a lack of literature regarding the application of drainage in RHA.Material and Methods:A total of 40 patients who underwent RHA were included in this prospective study. Simple randomization with an allocation ratio 1:1 was performed. Primary outcomes: total blood loss, hemoglobin drop, joint hematoma size in USG, infection. Secondary outcomes: blood transfusion rate, soft tissue hematomas, C-reactive protein levels, Visual Analogue Scale before and on 3rd day after surgery, Harris Hip Score before and 6 weeks after surgery. An intention to treat analysis was performed, with a 2-year follow up.Results:Statistically significant differences between groups was in blood loss: drainage 1559.78 ml, non-drainage 1058.27 ml, (p=0.029) and hemoglobin level on 1st day after surgery: drainage 10.58 g/dl, non-drainage 11.61 g/dl (p=0.0496). In terms of the other analyzed parameters, statistical differences were not found. Conclusion:Our study revealed that the use of suction drainage may lead to higher blood loss in the early postoperative period. Further studies are needed to evaluate our results.

Comparative study of suction drainage placement in cementless hip replacement among patients undergoing extended thromboprophylaxis: a prospective randomized study

Background The use of drains reportedly does not improve surgical outcomes after hip replacement. There is still a lack of strict recommendations for drain placement after primary hip replacement. This study aimed to assess the safety of not using suction drainage after primary hip replacement in a population of patients undergoing extended thromboprophylaxis. Methods In this prospective randomized study, all patients were qualified for primary hip replacement and were divided into two groups: with and without drainage. The inclusion criterion was idiopathic hip osteoarthritis. The exclusion criteria were secondary coxarthrosis, autoimmune disease, coagulopathy, venous/arterial thrombosis, hepatic/renal insufficiency, cement, or hybrid endoprostheses. We performed an intention-to-treat analysis. Clinical, laboratory, and radiographic parameters were measured for the first three days after surgery. Hematoma collection, due to extended thromboprophylaxis, in the joint and soft tissues was evaluated precisely. The patients underwent follow-up for 30 days. Results The final analysis included a total of 100 patients. We did not find any significant statistical differences between groups in terms of hip fluid collection (9.76 vs. 10.33 mm, with and without drainage, respectively; mean difference, 0.6 mm; 95 % confidence interval [CI] -2.8 to 3.9; p = 0.653), estimated blood loss (1126 vs. 1224 ml; mean difference, 97.1 ml; 95 % CI -84.1 to 278.2; p = 0.59), and hemoglobin levels on postoperative day 3 (11.05 vs. 10.85 g/dl; mean difference, 0.2; 95 % CI -2.1 to 2.5; p = 0.53). In addition, the other parameters did not show significant differences between groups. Notably, two cases of early infections were observed in the no-drainage group, whereas there were no such complications in the drainage group. Conclusions We conclude that the use of closed suction drainage after primary hip replacement is a safe procedure in patients undergoing extended thromboprophylaxis. Further research is warranted to validate these findings. Trial registration The study was successfully registered retrospectively at Clinicaltrial.gov with the identification number NCT04333264 03 April 2020.
