Pancreatic fistula after pancreaticoduodenectomy: the conservative treatment of choice

Background: A pancreatic fistula (PF) is the most common complication after pancreaticoduodenectomy (PD), and its reported incidence varies from 2% to 28%. The aim of the present study was to analyse the treatment of a complicated PF comparing the surgical approach with conservative techniques. Methods: From January 2000 through to August 2006, 121 patients were submitted for PD. The study consisted of 70 men and 47 women, with a median age of 60 years (SD +/- 12). The main indications for PD were pancreatic duct carcinoma in 52 patients (44.5%), ampullary carcinoma or adenoma in 18 (15.4%) and islet cell tumour in 11 (9.4%). Reconstruction by pancreatogastrostomy was performed in 65 patients (55.6%), and pancreatojejunostomy in 52 patients (44%). Results: Thirty-five patients (30%) developed a PF. Amongst these, 20 were managed conservatively and 14 were reoperated. These two groups of patients were compared with patients without a PF for analysis. There was no significant difference in the mean age, the gender ratio, American Society of Anesthesiologists (ASA) classification, surgical time and blood replacement, number of associated procedures, vascular resection and type of reconstruction between the three groups. There were five post-operative deaths (4.2%), three patients (21.4%) in the surgical treatment group (P < 0.01). Mean total number of complications (P = 0.02) and mean length of hospital stay (P < 0.001) were greater in the surgical group. The medium delay between the pancreatic resection and reoperation was 10 days (range, 3-32 days). Completion splenopancreatectomy was required in five patients whereas conservative treatment including debridement and drainage was applied in nine patients. Conclusion: The surgical approach for a PF is associated with a higher mortality and morbidity. There is no advantage in performing completion pancreatectomy (CP) instead of extensive drainage as a result of the same mortality and morbidity rates and the risk of endocrine insufficiency. In cases of complicated PF, radiological or surgical conservative treatment is recommended.

Conservative Treatment of Chondrodermatitis Nodularis Chronica Helicis with Topical Nitroglycerin

Background: Chondrodermatitis nodularis chronica helicis (CNCH) is a benign, painful, indurated inflammatory nodule arising on the pinna. Different treatment modalities have been used with varying efficacy rates. Despite lower efficacy, conservative methods are most desirable. Case reports: Three patients diagnosed with CNCH were treated with 0.4% topical nitroglycerin ointment, twice daily. These included two women and one man, aged 66, 86, and 60-years-old, respectively. Two painful nodules were located on the antihelix, and one on the helix. One patient had been previously treated with intralesional corticosteroids, and another with intralesional corticosteroids, CO2 laser and photodynamic therapy. All three patients experienced significant clinical and symptomatic improvement with topical nitroglycerin. No side effects were reported. Discussion: The etiology of CNCH is uncertain. Dermal and chondral ischemia arising from perichondrial arterial narrowing has been recently described as a possible cause for this benign condition, hence the potential of nitroglycerin as a smooth muscle relaxant and vasodilator. A previous report described significant improvement in twelve patients treated with 2% topical nitroglycerin. Conclusion: Topical nitroglycerin ointment appears to be a noninvasive alternative for the treatment of CNCH. A lower concentration (0.4%) may be as effective and with fewer side effects, but more studies are warranted.

Oral mucosal melanoma: conservative treatment including laser surgery.

Objective: To discuss the convenience of laser surgery as optimal treatment for melanoma of the oral mucosa.Patients and methods: A retrospective evaluation of four patients with primary oral melanomas treated at a single Cancer Institution in Mexico City.Results: Two patients were treated with resection of the melanoma with CO2 laser together with extraction of the involved dental organs and curettage of the alveolar walls. These two cases had melanoma in situ with multiple isolated foci. The third patient had a lesion with vertical growth, who was submitted to partial maxillectomy along with selective dissection of bilateral neck levels I-V with a negative report and the fourth patient had a history of oral nodular melanoma and presented with lymph node metastasis. According to follow-up status, there was no distant metastasis in any of the patients reported here.Conclusion: In our experience, conservative management with CO2 laser is adequate for melanomas of the oral mucosa with extraction of the dental organs and curettage of the alveoli to achieve complete surgical resection microscopically without sacrifice of the quality of life. Management of the neck is controversial. We recommend selective therapeutic resection of the neck only if it is found to be clinically positive. Elective dissection has not shown to have an impact in overall survival.

Grade I and II acromioclavicular dislocations: results of conservative treatment.

The purpose of this study was to assess the results of acute grade I and II acromioclavicular (AC) joint sprains treated by conservative measures. Between 1993 and 1997, 37 consecutive patients were treated conservatively for AC joint sprains, grade I and II in the Tossy classification. Of these patients, 4 were excluded (three lost to follow-up and one sustained a further AC injury), leaving a series of 33 patients. Among them, in 9 (27%), chronic AC joint pathology that required subsequent surgery developed at a mean of 26 months after injury. The remaining 24 were reviewed clinically and radiologically at a mean of 6.3 years (range, 4-8 years) after injury. At the latest follow-up, 17 of the 33 patients (52%) remained asymptomatic. Of the 24 patients reviewed, 7 complained of activity-related pain. Eight patients presented with residual anteroposterior instability. Tenderness at the AC joint as well as a positive cross-body test was observed in 12 patients. The mean Constant score at follow-up was 82 points. The x-ray films showed degenerative changes in 13 patients, ossification of the coracoclavicular ligaments in 2, an association of degenerative changes with ossification of the coracoclavicular ligaments in 3, and distal clavicular osteolysis in 3. Only 4 cases had no radiographic changes after this kind of AC injury. On the basis of these results, we conclude that the severity of the consequences after grade I and II AC sprains is underestimated.

Contribution de la biomicroscopie ultrasonore au traitement conservateur des mélanomes de l'uvée antérieure [Contribution of ultrasound biomicroscopy to conservative treatment of anterior uveal melanoma]

BACKGROUND: Ultrasound Biomicroscopy (UBM) is a new ophthalmological imaging technique essentially designed for the study of the anterior eye segment. Over the last 10 months, we've evaluated its contribution to the conservative treatment of anterior uveal melanoma's by means of accelerated proton beam irradiation. MATERIAL: Using UBM, we have examined 55 cases of uveal melanoma's, whose anterior border was situated at 6 mm or less from the limbus and that were consequently treated by proton beam irradiation. RESULTS: The presumed tumoral origin was the ciliary body's pars plicata in 13 cases and the pars plana or the choroid in 42 cases, 17 of which presented a tumoral invasion of the pars plicata. A pars plana detachment anterior to or surrounding the anterior tumoral border, was present in 22 cases. The height of the tumor could only be measured by UBM if it was less than 2.5 mm. Information gathered using UBM have contributed to an improvement of the therapy plan in 32 cases. CONCLUSION: Because of the strong attenuation of the high frequency ultrasound signal, UBM can only be used for the examination of intra-ocular structures situated in direct neighbourhood to the global wall. Despite this technical limitation, ist contribution to the planning of the conservative treatment of anterior uveal melanoma's by proton beam irradiation has appeared to be considerable.

Invasive bladder carcinoma: a pilot study of conservative treatment with accelerated radiotherapy and concomitant cisplatin.

From November 1992 to December 1997, 25 patients (inoperable or refusing cystectomy) were included in a prospective study to assess the feasibility, tolerance, and curative potential of accelerated radiotherapy (RT) and concomitant cisplatin. Median age was 74 years (range 49-86). Stage distribution was as follows: 1 T1, 10 T2, 8 T3, and 6 T4. Two patients had clinically positive pelvic nodes. The goal was to deliver a total dose of 40 Gy to the whole pelvis and bladder in 4 weeks using a concomitant boost of 20 Gy to the tumor or to the whole bladder during the third and fourth weeks (total dose 60 Gy), with daily cisplatin (6 mg/m(2)) before RT for patients with creatinine clearance > 50 ml/min. All but one patient completed the RT protocol. Daily cisplatin was successfully delivered in 18 patients. One patient presented with grade III ototoxicity. Diarrhea was scored grade III in two and grade IV in two patients. Acute urinary toxicity was scored grade III in one patient. Posttreatment late effects included bladder grade II and grade III in two patients and one patient, respectively; large bowel grade III in one; urethral grade III in one; and femoral head radionecrosis in one. Four-year overall and disease-specific survival rates were 23% and 35%, respectively. The latter was 60% for patients with T2 tumors. The 4-year actuarial locoregional control rate for all patients was 61%. In summary, accelerated RT and concomitant cisplatin is feasible with acceptable tolerance even in relatively old patients. Although outcome was better for patients with low-stage tumors, local control and survival rates appeared similar to those of standard RT schedules for a similar patient population.

An overview of conservative treatment for lower back pain

This article summarizes the available evidence on the management of patients with subacute or chronic low back pain. The largest part is devoted to nonspecific low back pain but the models of spinal stenosis and disk herniation/sciatica are also specifically addressed. The authors point out the limited evidence available and the importance of a tailored approach for the individual patient. As the effect sizes of most therapies are rather small (close to that of a placebo), patients' preferences and other variables important for individualized management are highlighted. The task for the practitioner is difficult and awareness of this is important. Some speculation regarding potential future ways of improving patient care are presented.

Minimally invasive fixation versus conservative treatment of undisplaced scaphoid fractures: a cost-effectiveness study.

This study compares the direct and indirect costs of conservative and minimally invasive treatment for undisplaced scaphoid fractures. Costs data concerning groups of non-operated and operated patients were analysed. Direct costs were higher in operated patients. Although highly variable, indirect costs were significantly smaller in operated patients and the total costs were higher in non-operated patients. In conclusion, operative treatment of scaphoid fractures is initially more expensive than conservative treatment but markedly decreases the work compensation costs.

Diverticulites sigmoïdiennes aiguës: vers un traitement de plus en plus conservateur [Acute sigmoid diverticulitis: toward a more and more conservative treatment].

La diverticulite colique aiguë est une pathologie fréquente en particulier chez les personnes âgées et d'origine caucasienne. La prévalence est plus importante chez les sédentaires et les personnes ayant un régime comprenant peu de fibres. Son diagnostic se base principalement sur la tomodensitométrie (CT) qui permet d'orienter la prise en charge thérapeutique. Ces dernières années, le traitement de la diverticulite aiguë a passablement changé avec notamment une évolution vers une restriction des indications du traitement chirurgical électif ou en urgence et une désescalade thérapeutique, avec réduction de l'antibiothérapie et du nombre d'hospitalisations. Cet article passe en revue l'épidémiologie, les moyens diagnostiques et la prise en charge de cette pathologie digestive courante. Acute diverticulitis of the colon is a frequent pathology especially among elderly people and people of Caucasian origin. The prevalence is higher among sedentary people and in people with low-fiber diet. Its diagnosis is mainly based on computed tomography (CT) that allows guiding the therapeutic management. Over the last few years the treatment of acute diverticulitis has passably changed with in particular an evolution toward a restriction of the elective and emergency surgery indications and a reduction of the antiobiotherapy and hospitalization number. This article reviews the epidemiology, the diagnostic tools, and the management of this frequent digestive pathology.

Conservative Treatment of Stress Urinary Incontinence: A Systematic Review with Meta-analysis of Randomized Controlled Trials

We performed a systematic review and meta-analysis of randomized controlled trials that studied the conservative management of stress urinary incontinence (SUI). There were 1058 results after the initial searches, from which 37 studies were eligible according to previously determined inclusion criteria. For the primary outcomes, pelvic floor muscle training (PFMT) was more efficacious than no treatment in improving incontinence-specific quality of life (QoL) scales (SMD = [1]1.24SDs; CI 95% = [1]1.77 to [1]0.71SDs). However, its effect on pad tests was imprecise. Combining biofeedback with PFMT had an uncertain effect on QoL (MD = [1]4.4 points; CI 95% = [1]16.69 to 7.89 points), but better results on the pad test, although with elevated heterogeneity (MD = 0.9g; 95%CI = 0.71 to 1,10g); group PFMT was not less efficacious than individual treatment, and home PFMT was not consistently worse than supervised PFMT. Both intravaginal and superficial electrical stimulation (IES and SES) were better than no treatment for QoL and pad test. Vaginal cones had mixed results. The association of IES with PFMT may improve the efficacy of the latter for QoL and pad test, but the results of individual studies were not consistent. Thus, there is evidence of the use of PFMT on the treatment of SUI, with and without biofeedback.

Efficacy of surgical versus conservative treatment in esophageal perforation: a systematic review of case series studies

PURPOSE: To evaluate the efficacy of surgical treatment for esophageal perforation. METHODS: A systematic review of the literature was performed. We conducted a search strategy in the main electronic databases such as PubMed, Embase and Lilacs to identify all case series. RESULTS: Thirty three case series met the inclusion criteria with a total of 1417 participants. The predominant etiology was iatrogenic (54.2%) followed by spontaneous cause (20.4%) and in 66.1% the localization was thoracic. In 65.4% and 33.4% surgical and conservative therapy, respectively, was considered the first choice. There was a statistically significance different with regards mortality rate favoring the surgical group (16.3%) versus conservative treatment (21.2%) (p<0.05). CONCLUSION: Surgical treatment was more effective and safe than conservative treatment concerning mortality rates, although the possibility of bias due to clinical and methodological heterogeneity among the included studies and the level of evidence that cannot be ruled out.

Conservative Treatment of Odontogenic Myxoma

Odontogenic myxomas (OMs) are nonencapsulated rare benign tumors that can occur in gnathic bones. They are locally invasive and have a high recurrence rate. Radiologically, OMs show a multilocular (in the majority of cases) or unilocular radiolucency, with either distinct or poorly defined margins. Histopathologically, OMs are characterized by spindle-, wedge-, or stellate-shaped cells loosely arranged in an abundant mucoid background. Myxomas are mainly asymptomatic. Radical surgery, excision, and enucleation followed by curettage of the surrounding bony tissue have all been advocated as treatment options. This study presents a successful case of conservative treatment of OMs with a 5-year follow-up.

Conservative treatment of a radicular cyst in a 5-year-old child: A case report

The present report describes the management of a radicular cyst in a 5-year-old child. The treatment comprised extraction of the primary teeth involved followed by marsupialization. A removable appliance with a resin extension penetrating into the cystic cavity was used to help decompress the lesion. This treatment allowed rapid healing of the lesion and eruption of the permanent incisors without the need for orthodontic treatment.

Conservative treatment of patients with periapical lesions associated with extraoral sinus tracts

This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. © 2007 The Authors.

Oncological Safety of Autologous Fat Grafting after Breast Conservative Treatment: A Prospective Evaluation

Autologous fat graft to the breast is a useful tool to correct defects after breast conservative treatment (BCT). Although this procedure gains popularity, little is known about the interaction between the fat graft and the prior oncological environment. Evidences of safety of this procedure in healthy breast and after post-mastectomy reconstruction exist. However, there is paucity of data among patients who underwent BCT which are hypothetically under a higher risk of local recurrence (LR). Fifty-nine patients, with prior BCT, underwent 75 autologous fat graft procedures using the Coleman's technique, between October 2005 and July 2008. Follow-up was made by clinical and radiologic examination at least once, after 6 months of the procedure. Mean age was 50 +/- 8.5 years, and mean follow-up was 34.4 +/- 15.3months. Mean time from oncological surgery to the first fat grafting procedure was 76.6 +/- 30.9months. Most of patients were at initial stage 0 (11.8%), I (33.8%), or IIA (23.7%). Immediate complication was observed in three cases (4%). Only three cases of true LR (4%) associated with the procedure were observed during the follow-up. Abnormal breast images were present in 20% of the postoperative mammograms, and in 8% of the cases, biopsy was warranted. Autologous fat graft is a safe procedure to correct breast defects after BCT, with low postoperative complications. Although it was not associated with increased risk of LR in the group of patients studied, prospective trials are needed to certify that it does not interfere in patient's oncological prognosis.
