Evaluation of Changes in Circulating Cell-Free DNA as an Early Predictor of Response to Chemoradiation in Rectal Cancer-A Pilot Study.

Background and Objectives: The objective of this study was to investigate quantitative changes in cell-free DNA (cfDNA) found in the bloodstream of patients with locally advanced rectal cancer who received neoadjuvant long-course chemoradiation, assuming a change in DNA fragments release during therapeutic stress. Materials and Methods: This was a prospective observational study that involved 49 patients who had three distinct pathologies requiring neoadjuvant chemoradiation: 18 patients with breast cancer, 18 patients with cervical cancer, and 13 patients with rectal cancer. Both breast cancer and cervical cancer patients were used as a control groups. Breast cancer patients were used as a control group as irradiation targeted healthy tissue after the tumor resection (R0), while cervical cancer patients were used as a control group to evaluate the effect of chemoradiation regarding cfDNA in a different setting (squamous cell carcinomas) and a different tumor burden. Rectal cancer patients were the study group, and were prospectively evaluated for a correlation between fragmentation of cfDNA and late response to chemoradiation. Blood samples were collected before the initiation of treatment and after the fifth radiation dose delivery. cfDNA was quantified in peripheral blood and compared with the patients' clinicopathological characteristics and tumor volume. Conclusion: Thirteen patients with locally advanced rectal cancer (T3/T4/N+/M0) were included in the study, and all of them had their samples analyzed. Eight were male (61.54%) and five were female (38.46%), with an average age of 70.85 years. Most of the patients had cT3 (53.85%) or cT4 (46.15%) tumors, and 92.31% had positive lymph nodes (N2-3). Of the thirteen patients, only six underwent surgery, and one of them achieved a pathological complete response (pCR). The mean size of the tumor was 122.60 mm3 [35.33-662.60 mm3]. No significant correlation was found between cfDNA, tumor volume, and tumor regression grade. cfDNA does not seem to predict response to neoadjuvant chemoradiotherapy and it is not correlated to tumor volume or tumor regression grade.

Predictive and Prognostic Role of Neutrophil to Lymphocyte Ratio in Rectal Cancer: A Case Control Study with Propensity Score Analysis.

Background: Neutrophil to lymphocyte ratio (NLR) is promoted as a marker reflecting the antitumoral inflammatory response. Herein, we aim to assess whether NLR at the time of diagnosis can predict response to neoadjuvant therapy and long-term survival in a matched cohort of rectal cancer patients. Methods: This is a case control study on rectal cancer patients who underwent standard oncological treatment and had NLR sampled at each stage. ROC curve was used to establish the cut off value of NLR at diagnosis. Two groups (high and low NLR) were compared. Kaplan Meier overall and disease-free survival (DFS) analysis was done comparatively between two groups of patients: low and high NLR. Pearson and Log Rank tests were used to establish statistical significance. Propensity score matching (PSM) was performed, and all variables were compared again on the matched subgroups. Results: One hundred patients were included and 54 were compared again after PSM. NLR at diagnosis did not correlate with tumor regression grade (p=0.77). High NLR at diagnosis (NLR 2.58) was not found to be significantly associated with worse overall survival (p=0.096) or DFS (p=0.128). Similar results were achieved after PSM, except when stage III subgroups were compared, where higher NLR was associated with worse DFS (p=0.04), while results for OS were borderline (p=0.05). Conclusions: Overall, a pretherapeutic high NLR ( 2.58) was not found to predict survival or response do neoadjuvant therapy in patients with rectal cancer. However, a higher NLR may be associated with worse outcomes in advanced colorectal cancer.

Laparoscopic versus open resection of primary colorectal cancers and synchronous liver metastasis: a systematic review and meta-analysis.

PURPOSE: Combined resection of primary colorectal cancer and associated liver metastases is increasingly common. This study compares peri-operative and oncological outcomes according to surgical approach. METHODS: The study was registered with PROSPERO. A systematic search was performed for all comparative studies describing outcomes in patients that underwent laparoscopic versus open simultaneous resection of colorectal primary tumours and liver metastases. Data was extracted and analysed using a random effects model via Rev Man 5.3 RESULTS: Twenty studies were included with a total of 2168 patients. A laparoscopic approach was performed in 620 patients and an open approach in 872. There was no difference in the groups for BMI (mean difference: 0.04, 95% CI: 0.63-0.70, p = 0.91), number of difficult liver segments (mean difference: 0.64, 95% CI:0.33-1.23, p = 0.18) or major liver resections (mean difference: 0.96, 95% CI: 0.69-1.35, p = 0.83). There were fewer liver lesions per operation in the laparoscopic group (mean difference 0.46, 95% CI: 0.13-0.79, p = 0.007). Laparoscopic surgery was associated with shorter length of stay (p < 0.00001) and less overall postoperative complications (p = 0.0002). There were similar R0 resection rates (p = 0.15) but less disease recurrence in the laparoscopic group (mean difference: 0.57, 95% CI:0.44-0.75, p < 0.0001). CONCLUSION: Synchronous laparoscopic resection of primary colorectal cancers and liver metastases is a feasible approach in selected patients and does not demonstrate inferior peri-operative or oncological outcomes.

Conservative surgery versus colorectal resection for endometriosis with rectal involvement: a systematic review and meta-analysis of surgical and long-term outcomes.

PURPOSE: The optimal surgical approach for removal of colorectal endometrial deposits is unclear. Shaving and discoid excision of colorectal deposits allow organ preservation but risk recurrence with associated functional issues and re-operation. Formal resection risks potential higher complications but may be associated with lower recurrence rates. This meta-analysis compares peri-operative and long-term outcomes between conservative surgery (shaving and disc excision) versus formal colorectal resection. METHODS: The study was registered with PROSPERO. A systematic search was performed on PubMed and EMBASE databases. All comparative studies examining surgical outcomes in patients that underwent conservative surgery versus colorectal resection for rectal endometrial deposits were included. The two main groups (conservative versus resection) were compared in three main blocks of variables including group comparability, operative outcomes and long-term outcomes. RESULTS: Seventeen studies including 2861 patients were analysed with patients subdivided by procedure: colorectal resection (n = 1389), shaving (n = 703) and discoid excision (n = 742). When formal colorectal resection was compared to conservative surgery there was lower risk of recurrence (p = 0.002), comparable functional outcomes (minor LARS, p = 0.30, major LARS, p = 0.54), similar rates of postoperative leaks (p = 0.22), pelvic abscesses (p = 0.18) and rectovaginal fistula (p = 0.92). On subgroup analysis, shaving had the highest recurrence rate (p = 0.0007), however a lower rate of stoma formation (p < 0.00001) and rectal stenosis (p = 0.01). Discoid excision and formal resection were comparable. CONCLUSION: Colorectal resection has a significantly lower recurrence rate compared to shaving. There is no difference in complications or functional outcomes between discoid excision and formal resection and both have similar recurrence rates.

The mesocolic apical fragment in complete mesocolic excision colectomies: Should it be analysed separately? A proof-of-concept study.

AIM: The aim of this work is to describe a protocol and assess the feasibility of harvesting and analysing the mesocolic apical fragment (MAF) for the presence of central lymph node (LN) metastasis and extra lymphatic free tumour cells in a random subgroup extracted from a cohort of complete mesocolic excision colectomies with central vascular ligation. METHOD: Forty-seven patients diagnosed with colorectal cancer were included. A 2/2 cm pyramid of tissue was cut around the central tie and sent for pathological examination. The MAF was sectioned into 16 slices. High-definition images were taken from the slices which were merged into a panoramic three-dimensional image of the MAF. The distribution of LNs in the MAF was quantified. Immunohistochemistry staining for cytokeratin 14 was used to identify isolated tumour cells and micrometastases in the extranodal tissue. RESULTS: No tumoural cells migrating through the apical zone, outside of the LNs, were identified. Margins of resection, mesocolic tissue and LNs were all negative in the subgroup of ultrastaged MAFs. The number of examined central LNs varied between 0 and 24, with positive MAF LNs being identified only in pN2 stages. The rate of positive apical LNs in our cohort was 4.2% (n = 2). CONCLUSIONS: The MAF can be easily extracted from standard specimens, allowing for accurate analysis of lymphatic and extra-nodal tumour cells on the central resection margins, in central LNs and in the apical mesocolic tissue. Future research on larger cohorts is required to establish if analysing the MAF has an impact on patient staging, prognosis and management.

Impact of Quilting Sutures on Surgical Outcomes After Mastectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Seroma after mastectomy and/or axillary lymph node dissection (ALND) is among the most common issue surgeons have to face in the early postoperative management of breast cancer. Using quilting sutures (QS) to aid in tissue approximation and decrease dead space is proposed as a simple technique to reduce seroma rate. We aimed to perform a systematic review, and analyse, in a meta-analytical model, the role of QS in improving wound outcomes and decrease volume, duration of drainage, and length of stay in hospital. METHODS: The study was registered with PROSPERO. A systematic search of the PubMed, EMBASE, and SCOPUS databases was performed for all comparative studies examining surgical outcomes in patients who underwent QS versus conventional closure (CC) after mastectomy ± ALND. RESULTS: Twenty-one studies with a total of 3473 patients (1736 in the study group and 1737 in the control group) were included based on the selection criteria. The study group showed significantly lower rates of seroma (p < 0.00001), total volume of drainage (p < 0.0001), days to drain removal (p < 0.00001), and length of stay (p < 0.00001) compared with the control group, while wound complication rates (surgical site infection, flap necrosis, hematoma, skin dimpling) were comparable between the two groups. CONCLUSIONS: QS are a reliable intraoperative technique that decrease seroma formation, volume of postoperative drainage, duration of drainage and length of hospital stay, and should be considered in mastectomies with or without ALND.

Clinical, histopathological and immunohistochemical features of glomus tumor of the nail bed.

PURPOSE: Glomus tumors account for 1-4% of benign hand tumors. In 65% of cases, it is located in the nail bed. Its rarity makes misdiagnosis problems relatively common. Symptomatology is characterized by the hallmark symptomatic triad. Imaging investigations may guide the diagnosis, but the diagnosis is made by pathological examination doubled by immunohistochemical (IHC) markers. PATIENTS, MATERIALS AND METHODS: We studied a group of seven female patients, aged 28 to 56 years. Clinical examination revealed the presence of the characteristic symptomatic triad. Ultrasound imaging tests were performed. RESULTS: Anatomopathological examination made a diagnosis of glomus tumor in all seven cases. IHC staining showed that tumor cells were positive for alpha-smooth muscle actin (α-SMA) and h-caldesmon in all seven cases and negative for cluster of differentiation 34 (CD34) in 72.14%. IHC stainings for p63, S100, cytokeratin (CK) AE1∕AE3 were negative in all cases. The clinical diagnosis completed by ultrasonography was histopathologically confirmed in all cases. CONCLUSIONS: Although the glomus tumor is a rare lesion, we need to be familiar with it because a diagnostic delay also implies a treatment delay which will lead to amplified suffering and even real disability due to the high-intensity pain in these cases.

Utility of "reposition-flap" in the reconstruction of the avulsed thumb.

ABSTRACT: Injuries that result in thumb amputation cause a loss of 50% of hand function. Microsurgical replantation remains the gold standard of thumb reconstruction techniques. The non-microsurgical technical variants of thumb reconstruction described so far aim to create a neo-thumb of adequate length, stable, opposable, sensitive, and last but not least esthetically pleasing appearance. Avulsion of the distal phalanx and the absence of the nail will determine a functional deficit but also an unesthetic appearance. When replantation is not possible or the patient refuses to "sacrifice" another anatomical region for thumb reconstruction, the "reposition-flap" technique can be used. Although often controversial, this surgical technique deserves proper attention and should be used in some cases. We studied a group of 32 patients with distal thumb amputations. In patients with amputations in zone II according to Tamai, with interphalangeal joint preservation, the thumb was reconstructed using "reposition-flap" with an O'Brien flap in 15 cases. In the remaining 17 cases where the amputation was at the level of the interphalangeal joint, we used the same technique, but the thumb neopulp was reconstructed with the Littler heterodigital neurovascular flap harvested from the ulnar border of the middle finger in 11 cases or radial border of the ring finger in 6 cases. The results were evaluated from a functional (Kapandji score), sensitive (2-point discrimination, Semmes-Weinstein test) but also esthetically (patient satisfaction) point of view. Donor site morbidity, cold intolerance, the presence of nail dystrophy, and bone resorbtion were also assessed. The disabilities of the arm, shoulder and hand score was evaluated for each patient. Although various surgical and microsurgical techniques for thumb reconstruction are described, when choosing the technique to use we must first consider patient's wishes. A well-informed patient will be able to make, with the surgeon, the best decision for him concerning the reconstruction option.

Arterial only anastomosis associated with modified Baudet technique in ear replantation: Case reports and literature review.

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

Value of ultrasonography in the diagnosis of carpal tunnel syndrome-a new ultrasonographic index in carpal tunnel syndrome diagnosis: A clinical study.

We analyze the effectiveness of ultrasonography in diagnosing carpal tunnel syndrome (CTS) and propose the use of sonographic index of median nerve (MN) in carpal tunnel (SIMNCT) in a diagnostic algorithm and in establishing a scale of severity.We studied a group of 344 patients with CTS symptoms, examining them by ultrasound. We measured in all patients, on the affected hand: the size of the cross-sectional area of the MN at carpal tunnel (CT) inlet and outlet, nerve morphology at passage through CT, the vertical thickness of the MN entering into the CT - G1, the lowest vertical thickness into the CT or leaving the CT - G2, the thickness of the MN in the transversal plane as entering in the CT - L. Normal values were considered the similar measurements taken on the healthy hand and we established as normal SIMNCT = 16%. We proposed the formula SIMNCT = 100% (1-G2/G1) in order to calculate the index.Statistics show a significant sensitivity of SIMNCT (P < .0001) compared with cross-sectional area (CSA) and flattening ratio in the diagnosis of CTS. Analyzing the SIMNCT developed by us, we demonstrated a sensitivity of 94.81% and a specificity of 99.66% in CTS diagnosis. Thereby, we propose a CTS severity classification: normal = 16%, mild = 16-19%, moderate = 19% to 28%, severe = 28% to 50%, very severe > 50%.Ultrasonography is an effective method of studying the morphology of the tunnel and compressed nerve at various CTS stages and determining the cause of compression. The SIMNCT is a valuable and practical indicator and it can be used in the CTS diagnosis.

Idiopathic tenosynovitis with rice bodies.

PURPOSE: Idiopathic tenosynovitis with rice bodies is a rare disease and its non-association with rheumatic diseases, tuberculosis infection or trauma is reported only in few cases in literature. PATIENTS, MATERIALS AND METHODS: Our study presents a series of five patients diagnosed with tenosynovitis with rice bodies at the flexor tendons of the upper limb. Medical history revealed no associated disease or trauma. Disease duration ranged between two months and four years, two patients presenting symptoms of acute carpal tunnel and three patients tumor mass. In one case, the tumor measured 210 mm in length and a tendon rupture was suspected. Laboratory and imaging investigations could not establish a specific associated pathology and a preoperative diagnosis. Surgical treatment consisting of synovectomy was performed in all patients. RESULTS: In all five cases, intraoperative appearance could easily determine the presence of rice bodies. Histopathological examination revealed typical aspect for rice bodies and make the diagnosis possible without the need for other more laborious processing (immunohistochemistry). The amount of rice bodies was directly proportional to disease duration. In all cases, the recovery was complete. After a median 30.4-month follow-up, no recurrence was detected. Subsequently performed laboratory investigations and specific tests did not reveal tuberculosis infection, rheumatic disease, or other diseases. CONCLUSIONS: This is the largest series of patients with idiopathic tenosynovitis with rice bodies and the bigger tumor mass reported to date. Synovectomy with removal of all rice bodies represents the optimal treatment. A longer disease course may be associated with a larger number of rice bodies, which may be associated with tendon rupture. The etiopathogenesis remains unclear, further studies being necessary to establish it.

Nail bed solitary neurofibroma: A case report and literature review.

RATIONALE: Nail bed solitary neurofibroma is an extremely rare tumor, with only 9 cases recorded in the literature so far. PATIENT CONCERN: We present the case of a 42-year-old female patient, with a history of a slowly growing tumor in the nail bed of the left index and no clinical features of type I neurofibromatosis. DIAGNOSIS: Nail bed solitary neurofibroma. INTERVENTION: The tumor was surgically removed and the pathology examination established the diagnosis of neurofibroma. OUTCOMES: The postoperative outcome was good, with no recurrence 12 months after surgery. LESSONS: We present the rarity of this type of tumor localized in the nail bed, taking into consideration the only 9 cases recorded in the literature. Nail bed solitary neurofibroma should be also included in the differential diagnosis of a nail bed tumor.

PELVIC ACTINOMYCOSIS MIMICKING A LOCALLY ADVANCED PELVIC MALIGNANCY--CASE REPORT.

We present the case of a former user of an intrauterine contraceptive device (IUD) for 10 years, diagnosed with a bulky, fixed pelvic tumor involving the internal genital organs and the recto sigmoid, causing luminal narrowing of the rectum, interpreted as locally advanced pelvic malignancy, probably of genital origin. Intraoperatively, a high index of suspicion made us collect a sample from the fibrous wall of the tumor mass, large Actinomyces colonies were thus identified. Surgery consisted in debridement, removal of a small amount of pus and appendectomy, thus avoiding a mutilating and useless surgery. Specific antibiotic therapy was administered for 3 months, with favorable postoperative and long-term outcomes. Pelvic actinomycosis should always be considered in the differential diagnosis of pelvic tumors in women using an IUD. The association of long-term antibiotic treatment is essential to eradicate the infection and prevent relapses.

Giant solitary gastric Peutz-Jeghers polyp mimicking a malignant gastric tumor: the largest described in literature.

A solitary Peutz-Jeghers polyp is defined as a unique polyp occurring without associated mucocutaneous pigmentation or a family history of Peutz-Jeghers syndrome. Gastric solitary localization is a rare event, with only eight reported cases to date. We report herein the case of a 43-year old woman who presented with upper gastrointestinal bleeding, severe anemia, weight loss and asthenia. Endoscopy revealed a giant polypoid tumor with signs of neoplastic invasion of the cardia, with pathological aspect suggesting a Peutz-Jeghers hamartomatous polyp. Computed tomography suggested a malignant gastric tumor and a total gastrectomy was performed. The pathological specimen showed a giant 150/70/50 mm polypoid tumor and immunochemistry established the final diagnostic of a Peutz-Jegers type polyp. This is the largest solitary Peutz-Jeghers gastric polyp reported until now, and the second one mimicking a gastric malignancy with lymph node metastasis.

[Surgery in advanced cervical cancer]. / Consideratii asupra tratamentului chirurgical în cancerul de col uterin avansat.

UNLABELLED: The aim of this study was to highlight the importance of surgical treatment in advanced cervical cancer (IIB-IIIB). MATERIAL AND METHOD: Data from 179 patients with cervical cancer, admitted in the Clinic of Emergency Surgery, "Sf. Ioan" Hospital, Iasi, between January, 1st, 2003 and December, 31st, 2009, were collected. RESULTS: A number of 11 cases (6.1%) cases were without any clinical response, so that they benefit by radical radiotherapy; a radical surgical intervention was performed in the other 168 cases (93.7%), in 4-6 weeks after chemotherapy. No intraoperative complications were evidenced, but after surgical intervention we recorded: urinary troubles--10 (6.5%); lymphedema--3 (1.9%); posttoperative intestinal occlusions--2 (1.3%); extended dynamic ileus--2 (1.3%); phlebitis--2 (1.3%).

[Therapeutic approach in kidney trauma. Assessments of 49 patients treated at surgical emergencies clinics]. / Orientari terapeutice în traumatismul renal. Evaluari pe un lot de 49 pacienti asistati în clinica de urgente chirurgicale.

UNLABELLED: The aim of this study is to contribute to efficiency of therapeutical interventions, using an optimal stadialisation followed by a maximum preservation of renal function. MATERIAL AND METHODS: A number of 49 cases with polytrauma, included urinary lesions, were studied between January, 2002 and December, 2009. Demographical, clinical, paraclinical data were collected, as well as those regarding therapeutical measures. RESULTS: From a number of 1436 cases with polytrauma, 49 (3.41%) suffered from urinary tract prejudices and 36 (73.46%) with major kidney lesions--11 (30.55%) severe at admission; 5 (13.89%) patients with multiple lesions and hypovolemic shock. The conservative treatment was applied in 24 (66.64%) cases and other types of surgical interventions for the other patients. CONCLUSIONS: The urinary apparatus is affected in aproximately 10% of cases of abdominal trauma due to road and falls from heights accidents, especially in patients of 26-50 age groups: 30.5% with severe lesions, 13.89% with hypovolemic shock at admission, and 1 death. The treatment was conservative in 66.64% of cases and various types of surgical interventions for the others patients.

[Urinary tract trauma: anatomo-lesional, etiological and clinical considerations]. / Consideratii anatomo-lezionale, etiologice si clinice in traumatismele aparatului urinar.

UNLABELLED: Urinary tract injuries are rare lesions and account for about 3%, of all injuries and 10% of abdominal trauma injuries. The aim of this study is to review retrospectively a series of patients with urinary tract injuries treated in a general surgery clinic. MATERIAL AND METHODS: A series of 41 consecutive patients with urinary tract trauma who hospitalized in Surgery Clinic of "St. John" Hospital of Iasi during a 7 years period (January 2002 - December 2008). The main analyzed variable was age, mechanism of injury, anatomical site of injury, associated injuries, and methods of treatment, morbidity and mortality. RESULTS: Urinary tract injuries accounted for 3.2% of all abdominal trauma injuries. Adults males were more affected with 90.2% of cases. Traffic road accident and falls represented over 50% of cases. Renal trauma were present in 73.7% of cases, and associated lesions were present in all cases. Conservative treatment was applied for 24 patients (58.5%), nephrectomy (total or partial) was performed in 9 cases, suture of the urethra 1 case, suture of the urinary bladder 5 cases and cystostomy in 3 cases. Conservative treatment failed in 24 cases (58.5%), urinary complications were present in 8 patients (19.5%) and one patient died due to associated lesions. CONCLUSIONS: Urinary tract injuries are rarely encountered in trauma settings, to a high index of suspicion is necessary to establish the diagnosis. Renal trauma is the most fervently lesions and conservative treatment represent feasible solution for these.

[Considering risk factors and prevention in uterine cervical cancer]. / Consideratii asupra factorilor de risc si a preventiei in cancerul de col uterin.

UNLABELLED: Cervical cancer is a disease with important medical and social involvements and a severe evolution in advanced stage. Its high incidence in Romania situated this country on the first place in Europe. MATERIAL AND METHOD: The paper analyzed retrospectively a sample of 51 cases suffering from cervical cancer in advanced stage. The most important risk factors, depending on environment, genetic and lifestyle peculiarities of patients, were quantified. RESULTS: Age groups of 35-65 were involved in 70% of cases, those of maximum genital activity in 50.9% of cases and after the menopause in 45% of cases. The sample features: medium level of education, low socioeconomic standards, precarious health education in 45.9% of women, over 50% never seing controlled with a Papanicolaou test or cytohormonal smear. Diagnosis was carried out in advanced stadium (IIB-IIIB) for 75% of cases. CONCLUSIONS: Though the cancer of uterine cervix is committed oneself to a precocious diagnosis, due to a low level of sanitary education, the absence of the prevention testing concerning cells of the vaginal-cervix, the deficit hygiene, the smoking, the cases are diagnosed tardily, in advanced loco regional stages.

[Gastroduodenal ulcer refractory to conservative treatment]. / Ulcerul gastro-duodenal refractar la tratamentul conservator.

This is a 20-year retrospective study on 205 patients in which surgery for gastroduodenal ulcer was performed. In 51 one of these patients (24,8%) surgery was required by drug therapy failure, cases labeled as drug-resistant ulcers. Some causes of drug therapy failure are discussed, failure being also recorded in patients who benefited from modem ulcer drugs that proved only partially effective. The authors emphasize that surgery can no longer represent a therapeutic option, an utter substantiation not only from the surgeon but also from the entire team of specialists in various investigation types and therapeutics being mandatory.
