Purpose The purpose of this study is to compare pain patterns and identify factors associated with residual shoulder pain after rotator cuf repairs using double-row and single-row techniques. Methods A cohort study was performed using patients who underwent arthroscopic rotator cuf repairs at our center in 2015. Patients were allocated according to the repair technique into an single-row (SR) group or a double-row (DR) group. Visual Analog Scale (VAS) scores for pain were assessed at 1 week, 3 months, 6 months, 12 months and 24 months after surgery. Functional and radiographic assessments were performed at least 24 months postoperatively. The proportion of patients with residual pain and factors associated with residual shoulder pain (VAS > 0 at the inal follow-up) were analyzed in both groups. Results Fifty-two patients were enrolled in the SR group, and 53 were enrolled in the DR group. The DR group appeared to have higher levels of pain 1 week (P < 0.001) and 3 months (P = 0.041) postoperatively, while at other time points, the pain intensity of the two groups was comparable. Fourteen (26.4%) and 25 (48.1%) patients in the DR and the SR groups, respectively, developed residual shoulder pain, (P = 0.022; RR 1.82). The univariate analysis and multiple regression revealed that a poorer quality of tendon tissue is related to residual pain in the SR group, whereas tendon retraction is associated with residual pain in the DR group. The rate of re-tear was similar between the two groups and between patients with and without residual pain. Conclusions The DR repair technique results in a greater intensity of pain than that of SR repair during the irst 3 months after surgery; however, patients who underwent DR repair presented a signiicantly lower proportion of residual shoulder pain and better tendon quality after 2 years. Poorer tendon quality and larger tendon retraction as determined intraoperatively were risk factors for residual pain. These results highlight the necessity of promoting healing on the grounds of residual pain prevention. Level of evidence II.
Background:A drainage tube is generally retained after an abdominal surgery, especially in cases of postoperative bleeding or exudation. In recent years, negative pressure drainage or vacuum sealing drainage (VSD) has been extensively applied. However, the use of VSD in laparoscopic surgery is still challenging and has been rarely reported. Purpose: To introduce a novel Blake drain applied with negative pressure in laparoscopic surgeries. Materials/Methods: Two bar-shaped cuts were made at the end of the drainage tube, with one deeper than the other, and there were no other side holes retained. Thirty patients aged 4-8 years in novel drainage tube (NDT) group received the novel VSD after laparoscopic appendectomy or laparoscopic pyeloplasty, while those in the control traditional drainage tube (TDT) group received traditional drainage using the tube bearing side holes. Results:Tissue plugging and other complications were not observed in patients of NDT group. Significant differences were found in volume of drainage and cases of tissue plugging between NDT and TDT groups (P<0.05). Conclusions: The novel technique is simple, safe and effective for VSD following laparoscopic surgery. It can prevent plugging of soft tissues into the tube and improve drainage effect.
