Recurrence of catamenial pneumothorax after surgical treatment]

We reported a case of catamenial pneumothorax that was recurrent after surgical treatment. A 43-year-old woman had sudden chest pain and dyspnea during menstruation. Right pneumothorax and pleural effusion were pointed out on chest X-ray films. When the patient was 31 years old, she received a diagnosis of catamenial pneumothorax and underwent thoracotomy for resection of diaphragmatic endometriosis. However, after surgery she experienced recurrence of right pneumothorax, and was accordingly treated with danazol. The patient decided to terminate medication by herself because her symptoms had disappeared. Several years after the cessation of medication, she experienced chest pain frequently during menstruation, but did not seek a medical check-up. She visited our department because of persistent chest pain in 1997. After the patient was hospitalized, pneumothorax was diagnosed and continuous drainage was performed. Although pneumothorax was alleviated by drainage, it recurred during the patient's next menstrual period. Open lung surgery was performed. Diaphragmatic endometriosis with a small hole and inflammatory thickened lesions on the visceral pleura of the lower lobe (S 6) were found and excised. Microscopic examination of the excised specimens showed endometriosis. Visceral pleural endometriosis has been histologically demonstrated in very few cases. After surgery, hormonal therapy was started. The patient has been well for 12 months without recurrence of pneumothorax. Both surgical and hormonal treatment were considered necessary for the treatment of catamenial pneumothorax in this case.     

Deciduosis of the Appendix During Pregnancy

Acute appendicitis is an important differential diagnosis in patients with right lower quadrant pain during pregnancy. Endometriosis, a hormone-related pathology, is another possibility. Patients with endometriosis are typically symptomatic before pregnancy. Stromal endometriosis is a variant of endometriosis that presents no symptoms before pregnancy but which occasionally presents with the new onset of symptoms during pregnancy. We report the case of a 35-year-old woman in her 8th month of pregnancy who presented with impending appendiceal rupture due to deciduosis of the appendix, a progesterone-related condition, during pregnancy. This case suggests that deciduosis/stromal endometriosis should be considered as a differential diagnosis of acute abdomen during pregnancy, even if the patient is asymptomatic before pregnancy.     

The surgical intervention: Earlier or never?

Crohn's disease (CD) is a chronic and progressive disease characterized by the presence of inflammation in different segments of the digestive tract, resulting in damages of the entire wall. Untreated or treated inappropriately, this eventually might result in stricturing and/or penetrating complications. Traditionally, the first line of treatment is medical, and surgery reserved for those who failed medical therapy. Considerable progresses have been made in the surgical therapy of CD over the past two decades. Some surgical interventions such as those consisting in the resection of long segments or leading to a definitive stoma should be avoided and performed only in case of treatment failure. On the other side, well-indicated and minimal invasive surgery can be considered as an alternative to long-term medical therapy for certain indications. The decision of performing early surgery should take in account the strategy that will be applied post-operatively. Decision making in multidisciplinary teams is paramount.     

Crohn's disease, ulcerative colitis or indeterminate colitis--how important is it to differentiate?

In most patients coming to the general practitioner or specialist with a history of bloody diarrhoea, bacteria or drugs are the most likely causative agents and it will be possible to make a diagnosis fairly easily. Because of differences in treatment, ulcerative colitis (UC) and Crohn's disease (CD) must however seriously be considered especially in younger patients, with severe symptoms and whenever the history is prolonged. A variety of colitides may indeed be clinically confused with UC and CD. Pathological mimics that should not be missed include infectious diseases such as Campylobacter colitis, yersiniosis, amoebiasis and others; drug-induced diseases (due to nonsteroidal antiinflammatory drugs...); diverticular disease-associated colitis; intestinal endometriosis; intestinal vasculitis and Beh?et's disease and iatrogenic conditions such as graft-versus-host-disease and radiation colitis. In most situations a precise diagnosis of these conditions should be possible when all data are available. The term "indeterminate colitis" is used, when a diagnosis of chronic idiopathic inflammatory bowel disease (IBD) is suggested, but the differential diagnosis between UC and CD can not be solved. This occurs in approximately 5% of all patients with IBD. Diagnostic problems can occur in acute fulminant colitis, acute prolonged colitis, chronic relapsing disease and pouchitis. Indeterminate colitis is essentially a temporary diagnosis. Surgical and medical treatment of these patients can be difficult. When surgical treatment is indicated, the type of surgery must be seriously considered. The clinical course of patients with indeterminate colitis is usually more severe when compared with classical UC and these patients require often more severe medical treatment. Diagnostic problems can also arise in longstanding IBD, either UC and CD. Relapse of symptoms can be due to intercurrent infection (CMV is one of the candidates). Medical treatment can influence the microscopic features and induce a discontinuous inflammation in UC, reminiscent of CD. In cases of doubt, the original biopsies should be reviewed to ascertain the diagnosis, and orient treatment.     

Sigmoid Colon Perforation Due to Endometriosis Not Associated with Pregnancy

A 38-yr-old woman presented with abdominal pain, hematochezia, and fever of 7 days' duration. Computerized tomographic scanning revealed a mass 6 cm in diameter adherent to the sigmoid colon. At surgery, the mass was determined to be an endometrioma with an associated tubo-ovarian abscess eroding the sigmoid colonic wall. This case, illustrating colonic perforation, represents a rare complication of intestinal endometriosis and, to our knowledge, represents the first reported case of colonic perforation secondary to endometriosis not associated with pregnancy. The clinical manifestations of intestinal endometriosis leading to perforation are reviewed.     

Bowel endometriosis: Colorectal surgeon’s perspective in a multidisciplinary surgical team

Endometriosis is a gynecological condition that presents as endometrial-like tissue outside the uterus and induces a chronic inflammatory reaction. Up to 15% of women in their reproductive period are affected by this condition. Deep endometriosis is defined as endometriosis located more than 5 mm beneath the peritoneal surface. This type of endometriosis is mostly found on the uterosacral ligaments, inside the rectovaginal septum or vagina, in the rectosigmoid area, ovarian fossa, pelvic peritoneum, ureters, and bladder, causing a distortion of the pelvic anatomy. The frequency of bowel endometriosis is unknown, but in cases of bowel infiltration, about 90% are localized on the sigmoid colon or the rectum. Colorectal involvement results in alterations of bowel habits such as constipation, diarrhea, tenesmus, dyschezia, and, rarely, rectal bleeding. Differential diagnosis must be made in case of irritable bowel syndrome, solitary rectal ulcer syndrome, and a rectal tumor. A precise diagnosis about the presence, location, and extent of endometriosis is necessary to plan surgical treatment. Multidisciplinary laparoscopic treatment has become the standard of care. Depending on the size of the lesion and site of involvement, full-thickness disc excision or bowel resection needs to be performed by an experienced colorectal surgeon. Long-term outcomes, following bowel resection for severe endometriosis, regarding pain and recurrence rate are good with a pregnancy rate of 50%.     

Diverticular disease: Update

Opinion statement Diverticular disease is an extremely common disease entity in our society. The major complication of diverticular disease, diverticulitis, can have quite variable presentations. In the acute setting, treatment is divided into nonsurgical (conservative) or surgical therapy. Cases of mild or “uncomplicated” disease benefit from a conservative approach involving antibiotic therapy. With more severe or “complicated” presentations (abscess, phlegmon, obstruction, fistula, or peritonitis), a more aggressive approach may involve percutaneous abscess drainage or urgent surgical therapy. This also may be required after a failed initial attempt at medical management. The decision regarding elective surgery after successful medical management of diverticulitis is more complicated. The primary goal is to minimize disease recurrence with as little morbidity as possible while maintaining a high quality of life. Recent evidence challenges indications for elective surgery. However, data on the natural history of recurrent diverticulitis are not clear enough to support altering current surgical guidelines. In addition, the increasing use of minimally invasive techniques with favorable outcomes for sigmoid colectomy must be considered. Prior to offering elective colectomy for diverticulitis, it remains important to individualize each case, giving special consideration to age, symptomatology, and recurrence. Ultimately, the decision for elective surgery is made by both the surgeon and a well-informed patient.     

Portopulmonary hypertension in liver transplant candidates

Pulmonary vascular disorders including portopulmonary hypertension(PoPHT) are among the common complications of liver disease and are prognostically significant. Survival is very low without medical treatment and liver transplantation. With advances in medical therapy for elevated pulmonary artery pressure(PAP) and liver transplant surgery, survival of patients with Po PHT and advanced liver disease is significantly improved. Because of the prognostic significance of Po PHT and the limited donor pool, a comprehensive preoperative cardio-pulmonary assessment is of great importance in cirrhotic patients prior to transplant surgery. Therefore, a detailed transthoracic Doppler echocardiographic examination must be an essential component of this evaluation. Patients with mild Po PHT can safely undergo liver transplant surgery. In cases of moderate to severe Po PHT, right heart catheterization(RHC) should be performed. In patients with moderate to severe Po PHT on RHC(mean PAP 35-45 mm Hg), vasodilator therapy should be attempted. Liver transplantation should be encouraged in cases that demonstrate a positive response. Bridging therapy with specific pulmonary arterial hypertension treatment agents should be considered until the transplant surgery and should be continued during the peri- and post-operative periods as needed.     

Multiple pyogenic liver abscesses caused by Streptococcus constellatus in the Amazon region. Case report

There are few studies reporting pyogenic liver abscess (PLA) caused by Streptococcus constellatus in the medical literature. S. constellatus is a comensal microorganism that belongs to the Streptococcus milleri’s bacteria group and is not considered to be pathogenic for humans. We report the case of a 23-year-old man with a 15-days history of abdominal pain in the right flank followed by daily fever, chills, nausea, vomits, sialism and jaundice. Physical examination revealed moderate jaundice (2+/4+), abdominal distention, generalized pain and tender over the right flank with positive Blumberg’s sign. Additionally, the liver was palpable 5 cm below the costal margin in the right midclavicular line. Abdominal Computerized Tomography showed multiple hypodense hepatic images suggestive of liver abscesses. The patient underwent surgical exploration of the abdomen through a sub-costal incision and, during operation ruptured abscess localized on the hepatic segment III was drained. Culture of the purulent material obtained at surgery yielded Streptococcus constellatus as the causative agent. Liver abscess is a potential life-threatening disease that must be treated as soon as possible with invasive approaches, if necessary, and bacteriological studies performed when possible, allowing isolation of causative agents and specific antibiotic therapy.     

PRL-secreting pituitary adenomas in pregnancy

Dopamine-agonists have significantly increased the number of pregnancies in women with micro- and macro-prolactinomas, as ovulation can be restored in the great majority of these patients. Thus, the main questions regard the possible consequences of high estrogen levels on tumor volume and the possible effects of D2-agonists on fetal development. While the risk of tumor increase is low in patients with prolactin secreting micro-adenoma (MIP), in PRL secreting macro-adenoma (MAP) patients the possibility of tumor growth is enhanced and influenced by previous treatment. Moreover, while it is well known that the exposition for only the first 4 weeks to bromocriptine (BRC) therapy does not affect the outcome of pregnancy, data on the use of BRC during the whole gestation are limited to just over 100 cases. Female pregnant patients with MIP, therefore, must be reassured and medical therapy suspended, with successive clinical follow-up. In the case of pregnant MAP subjects, the best approach from pre-pregnancy debulking, dopamine-agonist therapy interruption and BRC therapy continuation must be agreed on with the patient, and a careful follow-up instituted.     

Operative Differenzialtherapie des rheumatischen Handgelenks

The wrists are affected in the long-term in 90% of people with rheumatism and are often (42%) the first manifestation of a destructive disease. The functionality of the wrist and the whole hand is of great importance because in many cases loss of function of the wrists leads to severe limitations. Local and operative treatment of the wrist in rheumatoid arthritis (RA) is one of the main duties in rheuma-orthopaedics. For operative treatment there is a finely tuned differential therapeutic spectrum available. The diagnostic indications take the local and total pattern of affection, the current systemic therapy as well as patient wishes and patient compliance into consideration. In the early stages according to LDE (Larsen, Dale, Eek), soft tissues operations such as articulo-tenosynovectomy (ATS) are most commonly carried out. In further advanced stages osseus stabilisation must often be performed. At this point a smooth transition from partial arthrodesis to complete fixation is possible. After initial euphoria, arthroplasty of the wrist is being increasingly less used for operative treatment due to the unconvincing long-term results and high complication rate. With reference to the good long-term results of all operative procedures, in particular early ATS with respect to pain, function and protection of tendons, after failure of medicinal treatment and persistence of inflammatory activity in the wrist, patients should be transferred to an experienced rheuma-orthopaedic surgeon.     

Functioning gonadotroph adenoma with severe ovarian hyperstimulation syndrome: A new emergency in pituitary adenoma surgery? Surgical considerations and literature review

The authors reported 2 cases of functioning gonadotroph pituitary adenoma (FGPA) revealed by an ovarian hyperstimulation syndrome (OHSS) in young women. In the first case, OHSS was observed after GnRH analog injection. Pelvic echography revealed multiple voluminous ovarian cysts. Dopamine agonist posology failed in estradiol hypersecretion control, which necessitated endoscopic endonasal transsphenoidal surgery. The patient experienced improvement in pelvic pain as estradiol hypersecretion decreased during the first few postoperative days. Outcome was favorable, and her menstrual cycle was normal after two months. The second case was a young girl with spontaneous pelvic pain and elevated plasma FSH and estradiol levels. FGPA was confirmed on cerebral MRI. Dopamine agonists were introduced, and surgical removal of the pituitary tumor was scheduled for 7 days later. In the meantime, the patient was admitted and underwent surgery for bilateral adnexal torsion related to OHSS. The pituitary tumor was removed one week later. Outcome was favorable, and estradiol and FSH plasma levels were normal after 3 months. The ovarian cysts were no longer visible on echography after 3 months. Given the lack of efficacy of the current standard medical therapy, surgical removal of pituitary adenomas is the reference treatment for FGPA. The authors suggest that severe OHSS related to FGPA should be considered as a relative surgical emergency and that surgery should not be unduly delayed, given the unpredictable risk of adnexal torsion, particularly in case of voluminous ovarian cysts. The authors performed a literature review on this topic.     

Primary ovarian abscess in virginal young woman with huge endometriosis cyst: A case report

Rationale:Primary ovarian abscess which develops as an isolated lesion without simultaneous tubal infection is a rare entity. Ovarian abscess (OA) is a serious complication of pelvic inflammatory disease (PID) rarely seen in virginal girls. Early diagnosis and treatment are essential to prevent further sequela including infertility, ectopic pregnancy, and chronic pelvic pain.Patient concerns:A 19-year-old virginal girl who presented with abdominal pain and pelvic mass with no risk factors.Diagnoses:Laparoscopic surgery was performed to confirm a primary ovarian abscess in the adolescent virginal female with a huge endometriosis cyst.Intervention:Ovarian abscess with extensive intestinal adhesions was determined during the laparoscopic operation. Abscess drainage and postoperative antibiotic therapy cured the patient.Outcome:After the surgery, the CRP level on the day of discharge was 3.18 mg/d. The histological findings revealed a cystic tissue sample with the fibrous wall infiltrated by neutrophilic granulocytes, and ectopic endometrium, suggesting abscess formation in the ovary and endometriosis cyst.Lessons:Although primary ovarian abscess in an adolescent virginal female is rare, given the severity of outcomes following ovarian abscess, this pathology should be considered in the differential diagnosis of virginal adolescents with fever and abdominal pain.     

Pregnancy after liver transplantation：Four-year follow-up of the first case in mainland China

The safety and feasibility of pregnancy following liver transplantation（LT） have been accredited in a series of LT center.The first case in mainland China is reported.The follow-up data of a 22-year-old pregnant patient with end-stage liver disease undergone orthotopic liver transplantation were analyzed retrospectively.After surgery,the patient was uneventfully recovered and became pregnant 33 mo after LT.The patient was closely monitored and treated with a standard and individualized triple-drug immunosuppressive therapy throughout her pregnancy.Caesarean section was performed in March 18,2004,and a health live-born infant was delivered.After the delivery,a 4-year follow-up period indicated that the patient was satisfactory with her condition and her baby was healthy.Our case shows that a successful pregnancy following LT is possible and safe in women with end-stage liver diseases under close monitoring.Three factors including mother,baby,and transplanted liver function must be considered for the safety of high-risk pregnancies.     

Peyronie's disease: state of the art and future perspectives

Peyronie's disease (PD) is characterized by the onset of a fibrous plaque within the tunica albuginea of the penile corpora cavernosa, resulting in pain and bending during the erection, which can make the intercourse difficult or impossible. Evidence from literature supports the autoimmune etiology of PD, and suggests genetic and familiar conditions, penile traumatisms and history of genital tract diseases as risk factors, even though no definitive conclusions arise about the pathogenesis of the disease. Few randomized trials demonstrated that medical therapies, such as Vitamin E, Colchicine, Potassium amminobenzoate, Tamoxifen and injection therapy with Verapamil are effective in stabilizing the acute phase of the disease. Extracorporeal shock wave therapy (ESWT) and ionophoresis cannot be considered as first line or gold standard therapies. Satisfactory results have been published about Nesbit operation in large number of cases with low-stage disease, whereas plication procedures have shown significant rates of relapse. High incidence of long-term penile retraction have been reported in high-stage disease treated with plaque incision and simple graft insertion. Malleable, soft or inflatable prostheses combined with graft implant have given the best results in terms of penile straightening and lengthening and patients' satisfaction. In conclusion, the PD etiopathogenesis hasn't been clearly understood-yet, no medical therapy is fully effective; surgery remains therefore the gold standard in case of severe deformity and/or erectile dysfunction.     

Surgical and medical treatment in patients with acute severe ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory disease of the mucosa of the colorectum. The treatment of UC depends on the severity of symptoms and the extent of the disease. Acute severe colitis (ASC) occurs in 12–25% of patients with UC. Patients with ASC must be managed by a multidisciplinary team. Medically or surgically aggressive treatment is carried out with the final aim of reducing mortality. Intravenous administration of corticosteroids is the mainstay of the therapy. Medical rescue therapy based on cyclosporine or infliximab should be considered if there is no response to corticosteroids for 3 days. If there has been no response to medical rescue therapy after 4–7 days, the patient must undergo colectomy in emergency surgery. Prolonged observation is counterproductive, as over time it increases the risk of toxic megacolon and perforation, with a very high mortality rate. The best potential treatment is subtotal colectomy with ileostomy and preservation of the rectum. Emergency surgery in UC should not be seen as a last chance, but can be considered as a life‐saving procedure. Colectomies in emergency setting are characterized by high morbidity rates but the mortality is low.     

Severe portal hypertension secondary to arterio-portal fistula: salvage surgical treatment.

BACKGROUND: Arterio-portal fistulas (APFs) are rare vascular disorders of various origins that can lead to severe portal hypertension. Even if surgery was initially the treatment of choice, more recently, interventional radiological procedures have been considered as the first line therapeutic option. CASE REPORT: A man with no history of liver disease was admitted for abdominal pain and distension. Abdominal ultrasonography with Doppler, magnetic resonance imaging and computed tomography (CT) scan showed ascites, splenomegaly and a probable APF between the left branches of both the hepatic artery and portal vein, associated with hepatofugal portal flow. Upper gastrointestinal endoscopy revealed large oesophageal varices without bleeding. A celiac and mesenteric arteriography and a splenic arteriography were performed and confirmed the existence of multiple intrahepatic APFs. The initial treatment consisted of two sessions of percutaneous transcatheter endovascular embolization. Unfortunately, ascites worsened, and the patient did not respond to diuretic treatment. Therefore, a surgical treatment was considered to be the only suitable treatment because of the absence of improvement after embolization procedures. A left hepatectomy with hepatic artery ligation was performed. Clinical evolution was favourable; an improvement of ascites was obtained; control ultrasonography and CT scan disclosed no residual haemodynamic abnormality; and the portal vein was normal with a hepatopedal flow. Currently, 12 months after surgery, the clinical condition of the patient is good. CONCLUSION: Percutaneous treatment of portal hypertension by embolizing multiple large APF has been described to be an effective method. Nevertheless, failure of such conservative treatment is possible and must lead to a salvage surgery.     

Diagnóstico y tratamiento del mesotelioma pleural maligno

There are three major challenges in the diagnosis of malignant pleural mesothelioma: mesothelioma must be distinguished from benign mesothelial hyperplasia; malignant mesothelioma (and its subtypes) must be distinguished from metastatic carcinoma; and invasion of structures adjacent to the pleura must be demonstrated. The basis for clarifying the first two aspects is determination of a panel of monoclonal antibodies with appropriate immunohistochemical evaluation performed by highly qualified experts. Clarification of the third aspect requires sufficiently abundant, deep biopsy material, for which thoracoscopy is the technique of choice. Video-assisted needle biopsy with real-time imaging can be of great assistance when there is diffuse nodal thickening and scant or absent effusion. Given the difficulties of reaching an early diagnosis, cure is not generally achieved with radical surgery (pleuropneumonectomy), so liberation of the tumor mass with pleurectomy/decortication combined with chemo- or radiation therapy (multimodal treatment) has been gaining followers in recent years. In cases in which surgery is not feasible, chemotherapy (a combination of pemetrexed and platinum-derived compounds, in most cases) with pleurodesis or a tunneled pleural drainage catheter, if control of pleural effusion is required, can be considered. Radiation therapy is reserved for treatment of pain associated with infiltration of the chest wall or any other neighboring structure. In any case, comprehensive support treatment for pain control in specialist units is essential: this acquires particular significance in this type of malignancy.     

Surgical treatment of drug-resistant tuberculosis

The global emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis has led to the re-examination of surgery as a possible adjunctive treatment. We present the case of a 26-year-old HIV-seronegative patient with XDR pulmonary tuberculosis refractory to medical therapy. Surgical resection of the patient's solitary cavitary lesion was done as adjunctive treatment, and a successful outcome with a combination of surgery and drug therapy was achieved. We review the history of surgical therapy for tuberculosis and reports of its role in treatment of MDR and XDR tuberculosis. 26 case series and cohort studies were included, and together showed that surgical resection is beneficial in the treatment of drug-resistant tuberculosis. However, the results might not be applicable in all settings because investigations were observational and typically included patients with less severe disease, and all surgeries were done at specialised thoracic-surgery centres. Well designed studies are needed to establish the efficacy of surgery in treatment of drug-resistant tuberculosis.     

Steroid complications in patients with ulcerative colitis

Physicians treating patients with ulcerative colitis are confronted with the difficult task of deciding whether medical or surgical treatment is best for their patients. There are no definitive criteria to indicate when medical therapy should be exchanged for definitive surgery. Even in patients who respond well to glucocorticoid treatment, the side effects of these drugs may necessitate surgery. We reviewed the steroid complications of our operative cases retrospectively. Although ulcerative colitis was usually in remission, severe steroid complications were no longer tolerable and definitive surgery was required. We also reviewed the literature regarding the adverse effects of steroid. Because of advances in sphincter-preserving surgery, re-evaluation of the treatment of ulcerative colitis is necessary. Although conservative treatment remains the first choice, tolerance of irreversible side effects (especially in children) no longer seems to be justified. In such patients, early definitive surgery may offer more than it appears to sacrifice.
