Thulium laser resection versus plasmakinetic resection of prostates larger than 80 ml

Purpose

To compare the safety and efficiency of thulium laser resection of the prostate-tangerine technique (TmLRP-TT) and plasmakinetic resection of the prostate (PKRP) for aged symptomatic benign prostatic hyperplasia (BPH) patients with large volume prostates (>80 ml) in a prospective randomized trial with an 18-month follow-up.

Materials and methods

From January 2010 to November 2011, 90 BPH patients with large volume prostates were randomized for surgical treatment with TmLRP-TT (n = 45, group 1) or PKRP (n = 45, group 2). The preoperative and postoperative parameters were recorded and compared. All patients were evaluated at 1, 6, 12 and 18 months postoperatively using the International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum flow rate (Q _max), postvoid residual urine volume (PVR) and the five-item version of the International Index of Erectile Function score. All perioperative complications were also documented and classified according to the modified Clavien classification system.

Results

Compared with the PKRP group, the TmLRP-TT group had a statistically lower hemoglobin drop (0.86 ± 0.42 vs. 1.34 ± 1.04 g/dl, P < 0.01), shorter catheterization time (1.91 ± 0.85 vs. 2.36 ± 0.74 days, P < 0.01) and hospital stay (3.80 ± 0.46 vs. 5.02 ± 0.54 days, P < 0.01). Within the observation period of 18 months, both groups had significant postoperative improvement in IPSS, QoL, Q _max and PVR, although no difference was observed between the two groups. Only one patient receiving PKRP treatment required a blood transfusion perioperatively. During the 18-month follow-up, one patient in each group experienced urethral stricture and one patient in the PKRP group experienced bladder neck contracture. Minor complications that required no or noninterventional treatment occurred in 6 (13.33 %) of TmLRP-TT group (Clavien grade 1, 13.33 % and grade 2, 0 %) and 10 (22.22 %) of PKRP group (Clavien grade 1, 20.00 % and grade 2, 2.22 %). No severe complications required reinterventions in both groups (Clavien grade 3, 0 %; grade 4, 0 %; grade 5, 0 %).

Conclusions

Both TmLRP-TT and PKRP are safe and effective treatment options for large prostates that require resection. Taking into account less blood loss, shorter catheterization time and hospital stay, TmLRP-TT may be a better treatment for patients with large prostates.     

Apical temporal lobe resection; ��tailored�� hippocampus-sparing resection based on presurgical evaluation data

Background

It is the aim of epilepsy surgery in patients with lesional epilepsy for the surgeon to not only remove the lesion itself, but also the epileptogenic zone. Here, we report our experience with a modified temporal resection technique confined to the apical temporal lobe, i.e., sparing the hippocampal formation in patients with epileptogenic lesions in the anterior part of the temporal lobe. This apical temporal lobe resection (aTLR) includes tailored lesionectomy, amygdalectomy, and resection of the mesial structures only in the apex of the temporal lobe. This paper presents our surgical technical details and the outcome of aTLR.

Methods

Between 2001 and 2008, aTLR was performed in 61 patients. All patients underwent comprehensive presurgical evaluation including video-EEG monitoring, magnetic resonance imaging (MRI), and neuropsychological testing. All patients had a lesion in the apex of the temporal lobe and a normal hippocampus as seen in MRI, as well as intact memory functions in neuropsychological examination. There were 33 males (54.1%) and 28 females (45.9%). The mean age in years at epilepsy onset was 20.2?±?13.4, the mean age at epilepsy surgery was 32.1?±?11.9, the mean preoperative epilepsy duration was 11.8?±?8.8?years and the mean duration of follow-up was 2.1?±?1.3?years (range 0.5?C6?years).

Results

Fifty-four (88.5%) of 61 patients were in Engel Class 1 at 6?months, 38 (80.9%) of 47 at 2?years and nine (81.8%) of 11 at the 5?year follow-up. Histopathological examination showed tumors in 31 patients, FCD in ten patients, amygdala sclerosis in seven patients, cavernomas in six patients, unspecific reactions in eight patients, and gliosis in one patient. Surgical complications occurred in four patients: one had a permanent and three had transient complications which could be successfully treated. Fifty (82%) resections were considered to be complete resections as evaluated by serial postoperative MRI, seven patients (11.5%) had incomplete resection of the preoperative MRI lesion and in four patients (6.6%) it remained unclear. Fifteen patients (29.4%) were withdrawn from antiepileptic drugs for more than 2?years without relapse. Postoperative neuropsychological examination revealed worsening of memory performance in two patients (3.2%) and improved or no changes in the rest of the patients.

Conclusions

Apical temporal resection sparing the mesial temporal structures is an effective procedure with good long-term seizure outcome in patients with refractory epilepsy due to lesions confined to the apex of the temporal lobe.     

Gastric resection Billroth or Rydygier?

The Authors present the history of the first gastric resections and of the two men who first made this bold step in surgery. Although the famous Viennese surgeon Theodor Billroth is credited with the first gastric resection, known as the Billroth I procedure, the less well known Ludwik Rydygier from Chelmno, Poland, performed and described the procedure several months earlier. The Authors present the lives and major achievements of these two pioneering surgeons.     

Combined vascular resection in operative resection for hilar cholangiocarcinoma: does it work or not?

BACKGROUND: It is still not clear how combined vascular resection affects the outcome of patients with hilar cholangiocarcinoma. Our aim was to evaluate implications of combined vascular resection in patients with hilar cholangiocarcinoma by analyzing the outcomes of all patients who underwent operative resection. METHODS: A total of 161 of 228 consecutive patients with hilar cholangiocarcinoma underwent bile duct resection with various types of hepatectomy (88%) and pancreaticoduodenectomy (4%). Combined vascular resection was carried out in 43 patients. Thirty-four patients had portal vein resection alone, 7 patients had both portal vein and hepatic artery resection, and 2 patients had right hepatic artery resection only. The outcomes were compared between the 3 groups: the portal vein resection alone (34), hepatic artery resection (9), and non-vascular resection (118). RESULTS: Histologically-positive tumor invasion to the portal vein beyond the adventitia was present in 80% of 44 patients undergoing combined portal vein resection. Operative mortality occurred in 11 (7%) patients. The survival rates of the non-vascular resection group were better than that of the portal vein resection alone and the hepatic artery resection groups: 1, 3, and 5 years after curative resection, 72%, 52%, and 41% versus 47%, 31%, and 25% (P < .05), and 17%, 0%, and 0% (P < .0001), respectively. Multivariate analysis showed 4 independent prognostic factors of adverse effect on survival after operation; operative curability, lymph node metastases, portal vein resection, and hepatic artery resection. CONCLUSIONS: Although both portal vein and hepatic artery resection are independent poor prognostic factors after curative operative resection of locally advanced hilar cholangiocarcinoma, portal vein resection is acceptable from an operative risk perspective and might improve the prognosis in the selected patients, however, combined hepatic artery resection can not be justified.     

Transurethral resection of the prostate stricture management

For more than nine decades,transurethral resection of the prostate remains the gold standard for the surgical treatment of lower urinary tract symptoms due to benign prostatic obstruction.The occurrence of urethral strictures after transurethral resection of the prostate is one of the major late complications and has been reported as the leading cause of iatrogenic urethral strictures in patients older than 45 years who underwent urethroplasty.Although several postulations have been proposed to explain the urethral stricture after transurethral resection of the prostate,the exact etiology of urethral stricture after TURP is still controversial.Suggested etiological factors of urethral stricture formation after transurethral resection of the prostate include infection,mechanical trauma,prolonged indwelling catheter time,use of local anesthesia,and electrical injury by a stray current.One single treatment option is not appropriate for all stricture types.The management of urethral stricture following transurethral resection of the prostate includes minimally invasive endoscopic methods,including urethral dilation and direct visual incision,or open surgical procedures with varying urethroplasty techniques.Although scientific studies focusing on urethral strictures after transurethral resection of the prostate are relatively limited and sparse,we can apply the principles of urethral stricture management before making decisions on individual stricture treatment.     

Limited resection for early esophageal cancer?

BACKGROUND: Early squamous cell carcinoma (SCC) and early adenocarcinoma (AC) of the esophagus are potentially curable diseases. The crucial point in treatment is that the depth of tumor infiltration into the mucosal and submucosal layers is correlated with the rate of nodal metastases and therefore with long-term prognosis. METHODS AND FOCUS: In submucosal SCC with a high rate of nodal metastases curative resection can be achieved only by radical esophagectomy with systematic lymphadenectomy, which remains the treatment of choice for this tumor entity. In submucosal AC the Merendino procedure may offer an alternative since lymphatic invasion occurs at a later stage than in SCC, and locoregional lymph nodes can be adequately resected. Major advantages of this operation over radical esophagectomy include the complete resection of the entire Barrett segment and the lower postoperative morbidity and mortality. Vagal-sparing esophagectomy still lacks adequate oncological evaluation for it to be recommended except in stage I a tumors. For mucosal SCC and AC endoscopic mucosal resection is the treatment of choice but requires intensive follow-up since the rate of complete resections is lower than in limited and radical surgical procedures. On the other hand, a low postoperative morbidity and the functional integrity of the tubular esophagus support the use of endoscopic mucosal resection for mucosal cancer.     

Is laparoscopic left pancreatic resection justified?

BACKGROUND: We reviewed our experience of laparoscopic left pancreatectomy to establish the feasibility of this approach and the characteristics of the operating procedure. METHODS: Thirteen patients with a mean age of 60 years were deemed for a left pancreatectomy. Preoperative diagnoses were: nine mucinous cystadenoma and one insulinoma, intraductal mucinous ectasia, chronic pancreatitis with ductal stenosis, and distal pancreatic tumor. RESULTS: Operative mortality was nil. Two patients required conversion for bleeding from splenic vein injuries leading to a splenectomy in one case. The spleen was preserved in 10 cases. Postoperative course was uneventful in nine cases. Four patients experienced postoperative complications: one pancreatic fistula, two liquid cysts on the pancreatic margin, and one reoperation for bleeding from a trocar port. Length of stay ranged from 5 to 22 days. CONCLUSION: These preliminary results confirm that in selected cases laparoscopic resection of the left pancreas is feasible and safe.     

What influences reconvalescence after lung resection?

INTRODUCTION: Reconvalescence after lung resections underlies several influences. The aim of this study was to outline the effect of patient and operative factors. METHODS: Between 1/97 and 6/98 a cross sectional prospective study was undertaken at the University of Ulm. 125 patients with lung resections for various reasons via anterolateral thoracotomy were included. Variants thought to affect postoperative recovery were statistically analysed using uni- and multivariate analysis. A "good postoperative recovery" (GPR) was seen as at least two of the following criteria were fulfilled on the second postoperative day: Spitzer Index >/=6, FEV1 >40% of preoperative measurement, pain on LASA scale 相似文献   

Achieving RO resection for locally advanced gastric cancer: is it worth the risk of multiorgan resection?

BACKGROUND: In gastric adenocarcinoma, only complete resection (R0) translates into survival benefit. Given the potential for increased morbidity and mortality from multiple organ resection we asked the question as to whether extended (multiple organ) resection was justified for advanced gastric cancer. STUDY DESIGN: From July 1985 to July 2000, 1,283 patients underwent gastric resection for adenocarcinoma at Memorial Sloan-Kettering Cancer Center, and were entered and followed in a prospectively recorded database. Four hundred eighteen patients (33%) underwent primary resection and had one or more organs resected in addition to the stomach. Eight hundred twenty-six patients (64%) underwent gastrectomy alone, with 39 patients (3%) not undergoing gastrectomy. Clinicopathologic, operative, and morbidity data were evaluated in this group. Complications were categorized by severity on a scale from 0 to 5, 0 being no complication to 5 being death. Chi-square analysis and the logistic regression method were used to compare and estimate factors significantly associated with having a complication. RESULTS: Three hundred thirty-seven patients had a single additional organ resected, 63 had two organs, and 18 had three organs. Five hundred eighty complications occurred in 33% of patients (404 of 1,283). The perioperative mortality was 4% (48 patients). Logistic regression identified the number of organs resected, two or greater, to be predictive of complications (RR 2.0), as well as age greater than 70 years old (RR 1.57). When excluding minor complications (values 1 and 2), only the number of organs resected (RR 3.8) was a major factor for severe complications (values 3, 4, and 5). CONCLUSIONS: Resection of two or more adjacent organs in advanced gastric adenocarcinoma is associated with a greater risk of developing a complication. The use of a graded surgical complication scale is needed for better reporting and comparison of complications. Achieving an R0 resection should still be considered the goal, even in locally advanced gastric cancer, but resection of additional organs should be performed judiciously.     

Venous resection for adenocarcinoma of head of pancreas: Does extent of portal vein resection affect outcomes?

BackgroundVenous resection with pancreaticoduodenectomy (PD) increases resectability rates in patients with adenocarcinoma of head of pancreas. The effect of extent of portal vein resection on perioperative morbidity and mortality is less clear. This retrospective cohort study compares results of PD with and without venous resection and explores the influence of extent of vein resection on perioperative morbidity and mortality.MethodsTotal 96 patients underwent standard PD (PD) and 20 patients had en bloc venous resections (VR). VR group was divided into segmental (VR-S) (6/20 patients) and tangential (VR-T) (14/20 patients) groups based on segmental or tangential type of venous resections. The groups were compared for morbidity, mortality and survival.ResultsPD and VR groups had comparable perioperative morbidity (p = 0.140) and mortality (p = 0.358) with a significantly higher operative time in VR (p < 0.001). Perioperative morbidity and mortality were similar in VR-S and VR-T groups (p = 0.690 and p = 0.157 respectively). Operative time and estimated blood loss were significantly higher in VR-S group over VR-T (p = 0.019 and p = 0.002 respectively). Median survival was similar for PD and VR (15 and 15.5 moths respectively; p = 0.278) and VR-S and VR-T groups (17 and 12.5 months respectively; p = 0.550). Expected blood loss and operative time were found to be independent predictors of morbidity.ConclusionsVenous resection with PD is associated with morbidity, mortality and overall survival comparable to that after standard resection. The extent of venous resection does not seem to affect perioperative morbidity and mortality.     

Femoral head resection for painful hip subluxation in cerebral palsy: Is valgus osteotomy in conjunction with femoral head resection preferable to proximal femoral head resection and traction?

Patients with severe cerebral palsy who underwent either a femoral head resection with traction or a McHale procedure (femoral head resection and valgus osteotomy) were studied retrospectively and then contacted by telephone to assess whether removing the femoral head or proximal femur as a salvage procedure improved sitting tolerance, relieved pain, or improved hygiene. Twenty-seven patients (36 involved hips) were available for a retrospective chart and x-ray review, and over half (56%) of these patients or caretakers were able to complete a telephone questionnaire. Of the study cohort, 16 patients underwent femoral head resection with traction and 11 patients had a McHale procedure. The average age at surgery was 19 years and average follow-up was 3.4 years. For those in the McHale group, the length of stay in the hospital was shorter, the postoperative superior migration of the femoral head was less pronounced, and the surgical and medical complications were lower. The telephone survey showed that both groups had increased sitting tolerance and decreased pain, and both showed overall satisfaction with the surgical outcome.     

Laparoscopic ileocecal resection in Crohn’s disease

Background: Despite some encouraging preliminary results, the role of laparosropic surgery in the treatment of Crohns disease (CD) is a subject of controversy and still under evaluation. The aim of this case-matched study was to compare the postoperative course of laparoscopic and open ileocecal resection in patients with CD in order to define the potential role of laparoscopic surgery in CD. Methods: From 1998 to 2001, 24 consecutive patients with isolated Crohns terminal ileitis treated by laparoscopic ileocecal resection (laparoscopy group) were compared with 32 patients matched for age, gender, duration of disease, preoperative steroid treatment, fistulizing disease, and associated surgical procedure, and treated by open resection (open group). Results: In the laparoscopy group, four procedures (17%) were converted. There were no deaths. The morbidity rate was 20% in the laparoscopy group and 10% in the open group (NS). There was no significant difference between the two groups in operating time, size of bowel resection and resection margin, postoperative morphine requirement, resumption of intestinal function, tolerance of solid diet, or length of hospital stay. Conclusions: Laparoscopic ileocecal resection in CD is safe and effective, even for fistulizing disease. There are no significant differences between laparoscopic and open ileocecal resection, especially in terms of the mortality and mortality rates. Consequently, because laparoscopic surgery seems to offer cosmetic advantages, it should be considered the procedure of choice for patients with ileocecal CD.     

Primary chest wall neoplasms—resection and reconstruction

Background

Primary chest wall tumours are rare. We report our experience of primary chest wall neoplasms, their resection and reconstruction treated at our centre.

Methods

We reviewed a prospectively collected data from August 2013 to December 2014. Data included the mode of clinical presentation, imaging, biopsy, type of surgical resection and reconstruction, complications, morbidity and mortality. Recurrences if any and survival outcomes were recorded.

Results

A total of 14 patients were reviewed (M/F ratio was 9:5) with a median age of 35.5 years. Palpable mass (78.5 %) was a common presenting symptom. All patients underwent surgical resection, and reconstruction was required in 11 patients (78.5 %), with bone cement, mesh or greater omentum. Overall, 35.7 % (5 out of 14) received neoadjuvant therapy for downstaging and 14.2 % (2 out of 14) received adjuvant radiotherapy for positive margins. Early post-operative complications were seen in eight patients (57.1 %), and there was no in-hospital mortality. Factors that effected survival were resection margins and type of pathology.

Conclusion

Primary chest wall neoplasms need surgical resection. Multidisciplinary approach is necessary. The extent of tumour resection should not be compromised because of concerns over the ability to reconstruct large and complex defects. Prosthetic reconstruction is a safe and effective surgical procedure for major chest wall defects.

     

Laparoscopic body–tail pancreatic resection for insulinoma

A case of pancreatic insulinoma with a neuroglycopenic syndrome was treated with laparoscopic body--tail pancreatic resection. An en bloc splenectomy was required due to the close anatomic relation of the insulinoma with the splenic vein, as shown on intraoperative ultrasonography. The operative time was 4 h, and blood loss was minimal (<200 ml). Laparoscopic coagulating shears were used for the pancreatic mobilization, and an endoGIA was used for the section of the splenic vessels and the central pancreatic transection. The postoperative course was uneventful, and the patient was discharged in good condition on the 7th postoperative day. We concluded that laparoscopic access in patients with pancreatic disease is not only a valuable way to establish or confirm a diagnosis and assess the severity of the disease but also a safe way to perform distal pancreatic resection.     

Shorter postoperative atony after laparoscopic-assisted colonic resection?

BACKGROUND: The duration of the postoperative ileus after laparoscopic surgery remains a controversial topic. The aim of our study was to compare the restoration of intestinal motility after laparoscopically assisted and conventional resection of the distal colon in a canine model. METHODS: Two weeks after the implantation of three electrodes on the jejunum, the distal colon was resected in a laparoscopic-assisted or conventional procedure in two groups of four dogs each. Gastrointestinal motility was monitored by registration of the electromyograhic activity of the small intestine and by intermittent fluoroscopies of radiopaque markers. RESULTS: Electrical activity in the early postoperative period was characterized by the basic electrical rhythm and the absence of spike activity. The first postoperative activity front of the migrating motility complex (MMC), indicating the restoration of motility, occurred significantly earlier after laparoscopic-assisted resection (4.5 +/- 1 hr) than after conventional resection (31 +/- 10 h). Radiological observations showed a significantly delayed gastric emptying and a prolonged transit of radiopaque markers to the rectum after open surgery. CONCLUSION: These results support the hypothesis that laparoscopic-assisted resection of the colon leads to a shortened postoperative atony in comparison to open surgery.     

How much liver resection is too much?

BACKGROUND: Hepatic failure occurring after liver resection carries a poor prognosis and is a complication dreaded by surgeons. Inadequate reserve in the remaining parenchyma leads to a steady decrease in liver function, inability to regenerate, and progression to liver failure. For this reason, many methods to quantify functional hepatic reserve have been developed. METHODS: This article reviews the main methods used in the assessment of hepatic reserve in patients undergoing hepatectomy and their use in operative decision making. RESULTS: A range of methods to categorically quantify the functional reserve of the liver have been developed, ranging from scoring systems (such as the Child-Pugh classification) to tests assessing complex hepatic metabolic pathways to radiological methods to assess functional reserve. However, no one method has or is ever likely to emerge as a single measure with which to dictate safe limits of resectability. CONCLUSIONS: In the future, the role of residual liver function assessment may be of most benefit in the routine stratification of risk, thus enabling both patient consent to be obtained and surgical procedure to be performed, with full information and facts regarding operative risks. However, there is no one single test that remains conclusively superior.
