Objective To investigate the impact of conversion to open in laparoscopic rectal cancer radical resection (LRR) on postoperative recovery. Methods The data from Feb. 2003 to Feb. 2007 of 176 cases who were given LRR and 32 cases receiving conversion in LRR (CRR) were analyzed retrospectively, and were compared about operation time, hospitalization time, hospitalization expenses, intraoperative blood loss, recovery time of bowel movement and postoperative complications with 59 cases of open rectal cancer radical resection (ORR). Results There were no differences among LRR, CRR and ORR about operation time, hospitalization time, intraoperative blood loss and recovery time of bowel movement (Pgt;0.05). The hospitalization expenses of LRR and CRR were higher than that of ORR (P=0.001, P=0.001), there was no difference between CRR and LRR (P=0.843). But the postoperative complications rate of ORR was higher than those of LRR and CRR （P=0.023,P=0.004）. Conclusion Compared with ORR, LRR has relatively conversion rate, and then increases the hospitalization expenses.
Objective To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery. Methods A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference (P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed. Results All patients completed the surgery successfully, with no significant difference in surgical time between the two groups (P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences (P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant (P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery (P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups (P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time (P<0.05), but there was no significant difference between the two groups after surgery (P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups (P>0.05). Conclusion Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.
Objective To investigate the difference of effect between laparoscopic and open surgery in patients with traumatic rupture of spleen. Methods The literatures on comparison of laparoscopic and open surgery in patients with traumatic rupture of spleen were retrieved in PubMed, Web of Science, CNKI, Wanfang, and VIP databases from Jan. 2007 to Jan. 2017, and then Stata 12.0 software was applied to present meta-analysis. Results ① The condition during operation: compared with the OS group, operative time of the LS group was shorter [SMD=–0.71, 95% CI was (–1.12, –0.30), P=0.001] and intraoperative blood loss of the LS group was less [SMD=–1.53, 95% CI was (–2.28, –0.78), P<0.001]. ② The postoperative condition: compared with the OS group, the postoperative anal exhaust time [SMD=–2.47, 95% CI was (–3.24, –1.70), P<0.001], postoperative ambulation time [SMD=–2.97, 95% CI was (–4.32, –1.62), P<0.001], and hospital stay [SMD=–1.68, 95% CI was (–2.15, –1.21), P<0.001] of the LS group were all shorter. ③ The overall incidence of complications and the incidence of complications: on the one hand, compared with the OS group, patients in the LS group had a lower overall incidence of postoperative complications [OR=0.29, 95% CI was (0.19, 0.43), P<0.001]. On the other hand, compared with the OS group, patients in the LS group had lower incidences of infection [OR=0.27, 95% CI was (0.13, 0.55), P<0.001], ascites [OR=0.36, 95% CI was (0.13, 1.00), P=0.049], bleeding [OR=0.29, 95% CI was (0.10, 0.90), P=0.032], ileus [OR=0.34, 95% CI was (0.13, 0.90), P=0.030], incision fat liquefaction [OR=0.27, 95% CI was (0.08, 0.94), P=0.040], and incision rupture [OR=0.17, 95% CI was (0.03, 0.96), P=0.045]. However, there was no statistical difference on splenectomy fever [OR=0.41, 95% CI was (0.13, 1.27), P=0.123], pancreatic fistula [OR=0.40, 95% CI was (0.06, 2.63), P=0.343], liver function lesion [OR=0.36, 95% CI was (0.10, 1.34), P=0.127], and thrombosis [OR=0.33, 95% CI was (0.09, 1.22), P=0.097] between the 2 groups. Conclusions Laparoscopic surgery can not only significantly reduce the incidence of multiple complications of traumatic rupture of spleen, but also can speed up the recovery rate of postoperative recovery. Therefore, it is safe and beneficial in treatment of patients with traumatic rupture of spleen.
ObjectiveTo evaluate the effect of surgical treatment of vertebral artery stenosis and to summarize the experience.MethodThe clinical data of 6 patients undergoing surgical treatment from September 2018 to September 2019 were retrospectively analyzed.ResultsAll the procedures were successfully performed without intraoperative cerebral infarction, injury of thoracic duct or nerve disconnection by mistake. The operative time was 120 to 270 minutes, the median was 180 minutes. The blood loss was 50 to 150 milliliters, and the median was 65 milliliters. One patient suffered from Horner’s syndrome after the operation. One patient suffered from cerebral infarction on 4 days after the operation. During the follow-up of 3–10 months, three patients felt dizziness relieved and there were no anastomotic stricture or new cerebral infarction happened.ConclusionsSurgical treatment is safeand effective for vertebral artery stenosis. Revascularization of the carotid and vertebral arteries at the same time shouldbe avoided.
ObjectiveTo retrospective summarize the experience of endovascular repair and open surgery in the treatment of renal aneurysms in our single center.MethodsClinical data of 24 patients with renal aneurysm treated in our hospital from August 2012 to May 2018 were analyzed retrospectively. Nine patients undergoing surgical intervention were categorized as the open operation group, and ten patients who received endovascular repair were classified as the endovascular repair group. To compare and analyze the results of the two groups. Five patients who had refused surgery therapy will be analyzed separately.ResultsTwenty-four patients with seventeen females (70.8%) and seven males (29.2%) were enrolled in this study and nineteen patients with twenty-three aneurysms got repaired successfully. The endovascular repair group had shorter hospital stay compared with the open operation group [median: 10.5 (P25 6.3, P75 15.0) d vs. 21.0 (P25 17.0, P75 27.5) d］. One patient in the open operation group developed renal artery stenosis at 11 months after surgery and underwent reoperation by repair by successful stent placement. There were no other significant postoperative complications occurred in the two groups. No abnormal enlargement or rupture of the aneurysms were observed during the follow-up period in 5 unoperated patients.ConclusionsBoth open surgery and endovascular repair are effective means of treating renal artery aneurysms. Once the renal aneurysm ruptures, serious consequences will occur. Once a renal aneurysm is diagnosed, regardless of the size of the aneurysm, active surgical treatment is recommend.
ObjectiveTo analyze the therapeutic effects of open surgery and endovascular treatment for mesenteric venous thrombosis.MethodsThe clinical data of 22 patients with mesenteric venous thrombosis from March 2005 to January 2014 were analyzed retrospectively. One patient underwent open surgery including removal of necrotic small intestine and thrombectomy of superior mesenteric vein immediately admission to the hospital. Five cases were treated with simple anticoagulation and cured. Sixteen cases received thrombolytic therapy after primary anticoagulant therapy.ResultsOne case who underwent open surgery died of multiple organ failure at 72 h after the surgery. Five cases who received simple anticoagulant reached clinical relief finally. Sixteen patients who received thrombolytic therapy achieved recanalization totally or partially. Three cases died during follow-up (3 months to 7 years, average) of which 1 died of recurrence of acute superior mesenteric venous thrombosis, 1 died of myocardial infarction, and 1 died of stroke.ConclusionsFor patients with symptomatic mesenteric venous thrombosis, if there is no intestinal necrosis, there will be encouraging results by interventional thrombolytic therapy. And the treatment effect needs further experience accumulation in more cases.
Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.
ObjectiveTo summarize the diagnosis, surgical management, and outcomes of one case of complex unilateral renal artery aneurysm repaired by in situ open surgery. MethodThe clinical data of a patient with complex renal artery aneurysm admitted to the Department of General Surgery, West China Hospital of Sichuan University in December 2021 who underwent in situ open surgery were retrospectively analyzed. ResultsThe patient was a middle-aged (41 years old) female with a left renal artery aneurysm detected on physical examination. The renal artery three-dimensional CT imaging showed that the aneurysm was large in size and complex in anatomical structure; the aneurysm was located at the renal hilum, demonstrating multiple outflow tracts and close proximity to renal parenchyma and the ureter. Surgical management included in situ aneurysm resection combined with renal artery branch reconstruction and great saphenous vein bypass grafting. The operation duration was 5 h and the intraoperative urine output was 250 mL, and the intraoperative blood loss was about 400 mL. Four units of erythrocyte suspension, 200 mL of autologous recycled blood, and 400 mL of plasma were transfused during the operation. The results of the 36-month postoperative follow-up showed that the reconstructed renal arterial branches and the bridging vessel had satisfactory blood flow, and renal function was unaffected. ConclusionsThe results of this case suggest that in complex renal artery aneurysms involving multiple branches, in situ resection of the aneurysm followed by revascularization and main renal artery bypass grafting to restore flow is safe and feasible, and the long-term prognosis is good. However, it should be emphasized that the anatomy of renal artery aneurysms should be evaluated in detail preoperatively to determine the method of in situ revascularization. The results of the study also need to be further validated by larger samples and multicenter studies.
ObjectiveTo compare clinical outcomes between laparoscopic (LAP) and open surgery for non-metastatic colon cancer of T4a stage.MethodsWe retrospectively analyzed clinical data of non-metastatic colon cancer patients of T4a stage with confirmed pathological results who underwent curative resection in Peking Union Medical College Hospital between January 2011 and December 2017. These patients were allocated into LAP group (n=107, underwent laparoscopic radical operation) and open group (n=52, underwent open surgery).ResultsThere were no significant difference in operating time, number of lymph nodes harvested, number of positive lymph nodes, incidence of complications within 30 days, and Clavien-Dindo grading between the LAP group and open group (P>0.05), but intraoperative blood loss, postoperative exhaust time, and postoperative hospital stay in the LAP group were less than (shorter than) those of the open group (P<0.05).ConclusionLaparoscopic approach for non-metastatic colon cancer of T4a stage is safe and feasible, and it has advantages including less intraoperative blood loss, faster recovery, and shorter hospital stay.
The conventional total arch replacement (cTAR) with frozen elephant trunk implantation is commonly regarded as the gold standard for aortic pathologies involving ascending aorta and proximal aortic arch. By combining open supra-aortic vessels debranching and emerging endovascular technologies, hybrid arch repair (HAR) has been increasingly performed as a promising alternative in risky patients with comorbidities and frailties. Nevertheless, the advantages or disadvantages of hybrid arch procedures and cTAR in terms of survival and related outcomes remain controversial. This study is aimed to briefly review the role and results of HAR in the management of aortic arch pathology in comparison of contemporary cTAR.
