Clinical Efficacy of Organ-Preserving Pancreatectomy for Benign or Low-Grade Malignant Potential Lesion

The clinical usefulness of organ-preserving pancreatectomy is not well established due to technical difficulty and ambiguity of functional merit. The purpose of this study is to evaluate the clinical efficacy of organ-preserving pancreatectomy such as duodenum-preserving resection of the head of the pancreas (DPRHP), pancreatic head resection with segmental duodenectomy (PHRSD), central pancreatectomy (CP) and spleen-preserving distal pancreatectomy (SPDP). Between 1995 and 2007, the DPRHP were performed in 14 patients, the PHRSD in 16 patients, the CP in 13 patients, and the SPDP in 45 patients for preoperatively diagnosed benign lesions or tumors with low-grade malignant potential. The clinical outcomes including surgical details, postoperative complications and long-term functional outcomes were compared between organ-preserving pancreatectomy and conventional pancreatectomy group. Major postoperative complications constituted the following: bile duct stricture (7.1% [1/14]) in DPRHP, delayed gastric emptying (31.2% [5/16]) in PHRSD, pancreatic fistula (21.4% [3/14]) in CP. There were no significant differences in postoperative complications and long-term functional outcomes between two groups. Organ-preserving pancreatectomy is associated with tolerable postoperative complications, and good long-term outcome comparing to conventional pancreatectomy. Organ-preserving pancreatectomy could be alternative treatment for benign or low-grade malignant potential lesion of the pancreas or ampullary/parapapillary duodenum.     

A Prognostic Impact of Splenectomy in Laparoscopic Distal Pancreatectomy on Benign/Borderline Pancreatic Tumors: A Change of the Era

PurposeIn the past, spleen preservation during distal pancreatectomy (DP) was preferred; however, more recent studies reported comparable results between splenectomy and spleen preserving. We retrospectively reviewed patients in a single center who underwent laparoscopic DP with/without splenectomy, and evaluated the chronologic changes of surgical outcomes of the two procedures.Materials and MethodsPatients who underwent laparoscopic DP with or without splenectomy due to benign/borderline tumor from 2005 to 2019 were included in this study. We divided this period into Era 1 (2005–2012) and Era 2 (2013–2019), and compared the chronological evolution of surgical outcomes of laparoscopic distal pancreatosplenectomy (LDPS) to those of laparoscopic spleen-preserving distal pancreatectomy (LSpDP), including the long-term postoperative immunologic profiles.ResultsA total of 198 cases were included (LSpDP: 80 cases; LDPS: 118 cases). As the period changed from Era 1 to Era 2, the ratio of LSpDP decreased and the surgical outcomes of LDPS improved. In Era 1, LSpDP group showed superior results compared to LDPS group in terms of hospital days and postoperative pancreatic fistula ratio; however, in Era 2, the surgical outcomes showed no statistical differences. No significant differences were observed in all of the immunologic markers.ConclusionWe carefully conclude that during laparoscopic DP, combined splenectomy can be equivalent to spleen preserving in surgical and immunological outcomes, and inevitable splenectomy can be safely conducted.

Early outcomes of extra-thoracic debranching thoracic endovascular aortic repair for distal aortic arch disease

Thoracic endovascular aortic repair (TEVAR) combined with supra-aortic debranching is a promising approach for distal aortic arch disease, especially in high-risk patients. Most debranching TEVAR procedures for distal arch pathologies can now be performed by using extra-thoracic bypass and endovascular repair, without intra-thoracic manipulation needing sternotomy or thoracotomy. To compare the early outcomes of extra-thoracic debranching TEVAR with those of conventional arch replacement, we retrospectively reviewed data from 20 high-risk patients with distal aortic arch disease who underwent extra-thoracic debranching TEVAR and 16 patients who underwent total arch replacement from March 2009 to November 2011. Patient demographics, operative data, and outcomes in each group were evaluated and compared. The mean follow-up period was 22.4 ± 12.7 months. In the extra-thoracic debranching TEVAR group, primary technical success was achieved in all cases. One patient (5 %) died of low cardiac output syndrome within 30 days after surgery. Two patients had perioperative morbidities (10 %); both had a stroke during the procedure. No endoleak or graft migration was observed, and all bypass grafts remained patent. No patient had paraplegia, a new aortic event, or surgical site infection. In conclusion, the early outcomes of extra-thoracic debranching TEVAR in high-risk patients with distal aortic arch disease were satisfactory and encouraging, compared with conventional arch replacement. Extra-thoracic debranching TEVAR has the advantage of less invasiveness and no possibility of sternal infection.

The first experience of robot assisted spleen-preserving laparoscopic distal pancreatectomy in Korea

Spleen-preservation has recently been emphasized in benign and borderline malignant pancreatic diseases requiring distal pancreatectomy. Reports to suggest that laparoscopic distal pancreatectomy is feasible and safe have been increasingly published. Robotic surgical system has been introduced and is expected to provide unique advantages in laparoscopic surgery. However, robot-assisted pancreatic surgery has not yet been performed by many surgeons. A 45-year-old female patient with abdominal discomfort was found to have pancreatic cyst in the body of the pancreas. Mucinous cystic tumor of the pancreas was the most favourable preoperative diagnosis. She underwent spleen-preserving laparoscopic distal pancreatectomy by using da Vinci surgical robot system. Splenic artery and vein were so tightly adherent to the pancreatic cyst that segmental resection of splenic vessels was required. Postoperative course was uneventful. She was able to come home in 5 days after surgery. Postoperative follow up color doppler ultrasound scan, taken on 2 weeks after surgery, showed minimal fluid collection around surgical field and no evidence of splenic infarction with good preservation of splenic perfusion. Robot-assisted spleen preserving distal pancreatectomy is thought to be feasible and safe. Several unique advantages of robotic system are expected to enhance safer and more precise surgical performance in near future. More experiences are mandatory to confirm real benefit of robot surgery in pancreatic disease.     

The influence of tourniquet use and operative time on the incidence of deep vein thrombosis in total knee arthroplasty

OBJECTIVE:

To evaluate the association between tourniquet and total operative time during total knee arthroplasty and the occurrence of deep vein thrombosis.

METHODS:

Seventy-eight consecutive patients from our institution underwent cemented total knee arthroplasty for degenerative knee disorders. The pneumatic tourniquet time and total operative time were recorded in minutes. Four categories were established for total tourniquet time: <60, 61 to 90, 91 to 120, and >120 minutes. Three categories were defined for operative time: <120, 121 to 150, and >150 minutes. Between 7 and 12 days after surgery, the patients underwent ascending venography to evaluate the presence of distal or proximal deep vein thrombosis. We evaluated the association between the tourniquet time and total operative time and the occurrence of deep vein thrombosis after total knee arthroplasty.

RESULTS:

In total, 33 cases (42.3%) were positive for deep vein thrombosis; 13 (16.7%) cases involved the proximal type. We found no statistically significant difference in tourniquet time or operative time between patients with or without deep vein thrombosis. We did observe a higher frequency of proximal deep vein thrombosis in patients who underwent surgery lasting longer than 120 minutes. The mean total operative time was also higher in patients with proximal deep vein thrombosis. The tourniquet time did not significantly differ in these patients.

CONCLUSION:

We concluded that surgery lasting longer than 120 minutes increases the risk of proximal deep vein thrombosis.

Hybrid endovascular repair of thoracic aortic aneurysm in a patient with Behçet's disease following right to left carotid-carotid bypass grafting

Endovascular repair of inflammatory aortic aneurysms has been reported as an alternative to open surgical treatment. In selective cases, adjunctive bypass surgery may be required to provide an adequate landing zone. We report a case of endovascular repair of an inflammatory aortic aneurysm in a patient with Behçet''s disease using a carotid-carotid bypass graft to provide an adequate landing zone. A 45-yr-old man with a voice change was referred to our hospital with the diagnosis of saccular aneurysm of the distal aortic arch resulting from vasculitis. Computed tomography showed a thoracic aortic aneurysm with thrombosis. Right to left carotid-carotid bypass grafting was performed. After 8 days, the patient underwent an endovascular stent graft placement distal to the origin of the innominate artery. The patient was discharged with medication and without postoperative complications after 5 days. Hybrid endovascular treatment may be suitable a complementary modality for repairing inflammatory aortic aneurysms.     

Utility of vessel-sealing systems in thyroid surgery

The LigaSure vessel-sealing system (VSS) represents a new approach to intraoperative ligation. This clinical study retrospectively examined the utility of the VSS in thyroid surgery. In this study, we analyzed 56 consecutive patients who underwent thyroid surgery. Characteristics such as operative duration, the volume of intraoperative hemorrhage, and postoperative course were analyzed and compared between thyroid surgery using the VSS or conventional handtie methods. The present results indicate no significant differences in operative duration, volume of intraoperative hemorrhage, postoperative course, or duration of postoperative drainage between surgeries using the VSS or conventional methods. However, the postoperative hospital stay was found to be significantly shorter (p<0.05) with the VSS. No serious postoperative complications were encountered, and no significant differences were observed in the frequency of postoperative complications between methods. The VSS may simplify procedures for thyroid surgery, and hemostasis is effective for both thyroid vessels and thyroid parenchyma. However, further evaluation is warranted to adequately determine the relative merits of the VSS compared to conventional handtie methods.     

Transurethral resection of the prostate with a bipolar tissue management system compared to conventional monopolar resectoscope: one-year outcome

The purpose of the present study was to evaluate the efficacy and safety of bipolar transurethral prostatectomy (TURP) using the Gyrus PlasmaKinetic System compared with conventional monopolar TURP. This study included 102 patients with benign prostatic hyperplasia (BPH) who underwent TURP from January 2003 to March 2005. In all, 49 consecutive patients had bipolar and 53 had monopolar TURP. All patients were assessed by preoperative and postoperative International Prostate Symptom Score (IPSS), uroflowmetry, transrectal ultrasonography, operative time, weight of resected tissue, change in serum sodium and hemoglobin, duration of catheter use, length of hospital stay, and complication rates. Significant improvement was seen postoperatively in both groups, and no difference was observed in the resection time, weight of resected tissue, change in serum sodium and hemoglobin, improvement of IPSS and peak flow rate (Qmax), or complication rates over the 12-month follow-up in both groups. There was, however, a significant difference in duration of catheter use and hospital stay. Duration of catheter use (2.28 days vs. 3.12 days) and hospital stay (3.52 days vs. 4.27 days) were shorter in the bipolar group (p = 0.012 vs. p = 0.034, respectively). Our results demonstrate that bipolar TURP using the Gyrus Plasma Kinetic System is as effective as conventional monopolar TURP with the additional advantage of reduced length of catheter use and hospital stay. Bipolar TURP is a promising new technique that may prove to be a good alternative to conventional TURP in the future.     

The First Experiences of Robotic Single-Site Cholecystectomy in Asia: A Potential Way to Expand Minimally-Invasive Single-Site Surgery?

Purpose

Herein, we firstly present the robotic single-site cholecystectomy (RSSC) as performed in Asia and evaluate whether it could overcome the limitations of conventional laparoscopic single-site cholecystectomy.

Materials and Methods

From October 2013 to November 2013, RSSC for benign gallbladder (GB) disease was firstly performed consecutively in five patients. We evaluated these early experiences of RSSC and compared factors including clinicopathologic factors and operative outcomes with our initial cases of single-fulcrum laparoscopic cholecystectomy (SFLC).

Results

Four female patients and one male patient underwent RSSC. Neither open conversion nor bile duct injury or bile spillage was noted during surgery. In comparisons with SFLC, patient-related factors in terms of age, sex, Body Mass Index, diagnosis, and American Society of Anesthesiologist score showed no significant differences between two groups. There were no significant differences in the operative outcomes regarding intraoperative blood loss, bile spillage during operation, postoperative pain scale values, postoperative complications, and hospital stay between the two groups (p<0.05). Actual dissection time (p=0.003) and total operation time (p=0.001) were significantly longer in RSSC than in SFLC. There were no drain insertion or open conversion cases in either group.

Conclusion

RSSC provides a comfortable environment and improved ergonomics to laparoscopic single-site cholecystectomy; however, this technique needs to be modified to allow for more effective intracorporeal movement. As experience and technical innovations continue, RSSC will soon be alternative procedure for well-selected benign GB disease.

Clinical outcome of cardiac surgery in octogenarians

The purpose of this study was to investigate the operative results and the clinical outcomes for octogenarians who underwent cardiac surgery. Twenty consecutive octogenarians who had cardiac operations at Samsung Medical Center from October 1994 through December 2004 were included in the study. The medical records were retrospectively reviewed and the follow-up results were obtained by the interview. The patients were 15 men and 5 women, and their mean age was 83.1 yr (range: 80-89 yr). The surgical priority was urgent for 5 patients and it was elective for 15 patients. Coronary artery bypass grafting (CABG) was performed in 14 patients, valve surgery was performed in 4 patients and CABG plus valve surgery was performed in 2 patients. There was one hospital death on day one after urgent CABG in an 80-yr-old man who had left main coronary artery occlusion. There were three deaths during the follow-up. Sudden death occurred in one patient at 2 months after valve surgery, and there were two non-cardiac deaths at 12 and 14 months, respectively, after CABG. Non-fatal postoperative complications occurred in 2 of 5 urgent patients and in 3 of 15 electives. The survival rate for the 19 hospital survivors at 24 months after surgery was 80% and the mean follow-up period was 22.5 months (range: 1-58 months). In conclusion, cardiac surgery could be performed within acceptable limits of the risk and its long-term results could be expected to be favorable for the octogenarians.

Operative Procedure for Laparoscopy-Assisted Vagus Nerve and Pylorus-Preserving Gastrectomy (LAVNPPG) for Early Gastric Cancer

Laparosocpy-assisted pylorus-preserving gastrectomy (LAPPG) is a widely accepted surgical procedure for the treatment of early gastric cancer in the middle third of the stomach. We have been performing this operation since 2007. Compared with traditional distal gastrectomy, LAPPG has postoperative nutritional benefits for patients. However, this procedure preserves only the pyloric branch of the vagus nerve and not the celiac branch. We found that patients retain a large amount of residual food in the gastric remnant, which interferes with the detection of secondary cancer on endoscopic follow-up. To improve the pyloric function and postoperative gastrointestinal motility, we changed our procedure during 2009 to preserve both the pyloric and celiac branches of the vagus nerve, and we named this new procedure laparoscopy-assisted vagus nerve and pylorus-preserving gastrectomy (LAVNPPG). From 2009 to 2011, 11 patients underwent LAVNPPG at our hospital. Retrospective comparison of the safety of operation, postoperative complications, and condition of the gastric remnant between LAPPG (n = 13) and LAVNPPG (n = 11) found that the occurrence of postprandial stasis and food residue in the gastric remnant tended to be lower following LAVNPPG, though the differences were not significant. These findings indicate that LAVNPPG may be an operative procedure that could replace LAPPG.     

股骨颈骨折全髋关节置换后异体血输注的影响

背景：人工髋关节置换成为目前治疗移位性股骨颈骨折效果较为肯定的方法,因其围手术期失血量较多,致使很多患者需要输血,而输血本身有一定的成本和风险。 目的：探讨股骨颈骨折患者全髋关节置换后异体血输注的相关影响因素,进一步指导并完善在临床工作中血液管理。 方法：对接受全髋关节置换的275例股骨颈骨折患者进行回顾性分析,比较不同性别、年龄、体质量指数、置换前血红蛋白水平、术中出血量、双下肢静脉血栓、置换后抗凝方式、手术时间、假体类型等对置换后异体血输注的影响,以及对异体血输注的预测价值。 结果与结论：比较男性患者与女性患者全髋关节置换后的输血量时发现两者差异无显著性意义(P > 0.05),而在输血率方面两者差异具有显著性意义(P < 0.05)。两组内体质量指数≤ 25 kg/m²的患者和> 25 kg/m²的患者在输血量及输血率上组间差异均无显著性意义(P > 0.05)。年龄、置换前血红蛋白水平和置换过程中出血量是股骨颈骨折患者全髋置换后异体血输注的影响因素,而性别、体质量指数、抗凝方式、双下肢静脉血栓、手术时间、假体类型及术后引流量对术后异体血输注的影响不大。提示,根据影响因素所建立的模型公式对临床上评估和预测置换后异体血输注的风险具有一定的应用价值。
