Article Abstract
Background And Aims: The use of sutures to strengthen the anastomosis after rectal cancer surgery to reduce the possibility of anastomotic leakage has been debated. The aim of this systematic review and meta-analysis was to investigate the influence of intraoperative anastomotic reinforcing sutures on anastomotic leakage of double-stapling anastomosis for laparoscopic rectal cancer surgery.
Methods: A systematic search of PubMed, Embase, Web of Science, and Cochrane databases was performed to identify literature examining anastomotic leak as the primary outcome to compare studies of laparoscopic surgery for rectal cancer using the double-stapling anastomosis technique with or without intraoperative anastomotic reinforcement with sutures.
Results: A total of 1122 rectal cancer patients from 5 nonrandomized studies were included in the research. In the combined trial, intraoperative anastomotic reinforcement sutures significantly reduced the incidence of anastomotic leakage in patients who underwent laparoscopic rectal cancer surgery (OR, 0.32; 95% CI, 0.19-0.55; p < 0.0001). With or without intraoperative anastomotic reinforcing sutures, the incidence of postoperative reoperation for anastomotic leak did not differ substantially (OR, 0.32; 95% CI, 0.08-1.21, p = 0.09). Moreover, the surgery was prolonged due to anastomotic reinforcement with sutures (OR, 6.64; 95% CI, - 6.18 to 19.47, p = 0.31).
Conclusions: Intraoperative anastomotic reinforcement with sutures may be associated with a lower incidence of anastomotic leakage. The amount of research evidence is limited because most of the studies analyzed did not include patients with factors such as neoadjuvant therapy or prophylactic stomas. Therefore, additional multicenter randomized controlled studies with larger size samples are needed to support the validity of the approach.

This study explores effective treatment methods for chronic secondary lymphedema after radical cervical cancer surgery combined with pelvic lymphadenectomy. In cases where conservative treatment was ineffective, we investigated whether multiple injections of indocyanine green can effectively improve the outcomes of lymphatic-venous anastomosis under microscopy. Preoperative lymphatic imaging was used to localize functional vessels, guiding distal left lower limb lymphatic reconstruction.

Small intestinal diverticulosis is a rare condition, often asymptomatic until complicated with diverticulitis, bleeding, obstruction, or perforation. It predominantly affects elderly men and may present concomitantly with colon diverticulosis. We report the case of a 94-year-old Hispanic woman brought to the emergency department presenting with an acute abdomen.

Aim Of The Study: To present a case series of four pediatric patients with PDPV, each with a different clinical presentation and surgical management.
Methods: We retrospectively reviewed four cases of PDPV managed at our institution. Two cases were associated with extrahepatic biliary atresia (EHBA) and discovered incidentally during surgery.
Patients with cardiovascular compromise are likely to develop hypotension upon receiving even small doses of sedatives. On the other hand, patients with severe dental phobias or with intellectual disability who have a severe gag reflex often require deeper levels of anesthesia. Thus, achieving an optimal level of anesthesia can be difficult in patients with cardiovascular compromise because of the relatively narrow range of sedative dosing capable of providing sufficient sedation to prevent the gag reflex without compromising hemodynamics.

Background: Tracheobronchial injuries (TBI) are rare yet potentially fatal complications of blunt chest trauma, often underdiagnosed due to nonspecific clinical manifestations.
Case Presentation: We report the case of an 11-year-old Arab girl who developed progressive dyspnea two months after a motor vehicle accident initially managed conservatively. Imaging revealed complete atelectasis of the right lung and obstruction of the right main bronchus by granulation tissue.
