Infiltration of Bupivacaine and Triamcinolone in Surgical Wounds of Milligan-Morgan Hemorrhoidectomy for Postoperative Pain Control: A Double-Blind Randomized Controlled Trial.

BACKGROUND: Pain management after hemorrhoidectomy continues to be challenging. OBJECTIVE: The aim of this study was to evaluate the effectiveness of infiltration of bupivacaine hydrochloride and triamcinolone acetonide in surgical wounds of Milligan-Morgan hemorrhoidectomy for postoperative pain relief. DESIGN: A double-blind randomized controlled clinical trial was conducted between May 2015 and June 2019. SETTINGS: This study was carried out in a secondary referral hospital center in Spain. PATIENTS: Patients who underwent an elective Milligan-Morgan hemorrhoidectomy for grade III-IV hemorrhoids were included. INTERVENTIONS: Patients allocated in the intervention group received a single infiltration of bupivacaine and triamcinolone and patients allocated in the control group did not receive any intervention. MAIN OUTCOMES MEASURES: The primary end point was the median of maximum pain by visual analog scale during the 48 hours of hospital stay. Secondary end points were pain at follow-up, pain during defecation, analgesic requirements, wound healing rate, and complications. RESULTS: A total of 128 patients were randomly assigned (64 in each group). The median of maximum pain score at 48 hours was 3 points in the intervention group and 6 points in the control group, which was significantly different ( p < 0.05). No differences were observed regarding pain during defecation. Morphine requirements were significant lower in the intervention group (6.3% vs 21.9% patients; p = 0.01; 5 vs 23 cumulative doses; p = 0.01). Wound healing and complication rates were similar in both groups. LIMITATIONS: Use of placebo was not considered in the control group ("intervention group" vs "control group" clinical trial). Data regarding pain or other complications at 48 hours postoperatively were pooled and expressed as median of values. CONCLUSIONS: Infiltration of surgical wounds with bupivacaine and triamcinolone decreases postoperative pain and reduces morphine requirements in Milligan-Morgan hemorrhoidectomies.

Adjustable Gastric Banding Conversion to One Anastomosis Gastric Bypass: Data Analysis of a Multicenter Database.

INTRODUCTION: One anastomosis gastric bypass (OAGB) has been proposed as a rescue technique for laparoscopic adjustable gastric banding (LAGB) poor responders. AIM: We sought to analyze, complications, mortality, and medium-term weight loss results after LAGB conversion to OAGB. METHODS: Data analysis of an international multicenter database. RESULTS: One hundred eighty-nine LAGB-to-OAGB operations were retrospectively analyzed. Eighty-seven (46.0%) were converted in one stage. Patients operated on in two stages had a higher preoperative body mass index (BMI) (37.9 vs. 41.3 kg/m2, p = 0.0007) and were more likely to have encountered technical complications, such as slippage or erosions (36% vs. 78%, p < 0.0001). Postoperative complications occurred in 4.8% of the patients (4.6% and 4.9% in the one-stage and the two-stage group, respectively). Leak rate, bleeding episodes, and mortality were 2.6%, 0.5%, and 0.5%, respectively. The final BMI was 30.2 at a mean follow-up of 31.4 months. Follow-up at 1, 3, and 5 years was 100%, 88%, and 70%, respectively. CONCLUSION: Conversion from LAGB to OAGB is safe and effective. The one-stage approach appears to be the preferred option in non-complicate cases, while the two-step approach is mostly done for more complicated cases.

Management of symptomatic uncomplicated diverticular colon disease: A systematic review of diagnosis and treatment. / Enfermedad diverticular de colon no complicada sintomática: revisión sistemática del diagnóstico y tratamiento.

Symptomatic uncomplicated diverticular colon disease (SUDCD) is a highly prevalent disease in our setting, which significantly affects the quality of life of patients. Recent changes in understanding the natural history of this disease and technological and pharmacological advances have increased the available options for both diagnosis and treatment. However, consensus regarding the use of these options is scarce and sometimes lacks scientific evidence. The objective of this systematic review is to clarify the existing scientific evidence and analyse the use of the different diagnostic and therapeutic options for SUDCD, comparing their advantages and disadvantages, to finally suggest a diagnostic-therapeutic algorithm for this pathology and, at the same time, propose new research questions.

Bariatric Surgery in Patients with Obesity and Ventricular Assist Devices Considered for Heart Transplantation: Systematic Review and Individual Participant Data Meta-analysis.

BACKGROUND: Class II obesity (body mass index BMI ≥35 kg/m2) is a contraindication to heart transplantation (HT). Although few single-center studies (case reports/series and small cohorts) have reported promising outcomes of bariatric surgery (BS) in patients with obesity and ventricular assist devices, low sample sizes have made their analysis and interpretation challenging. METHODS AND RESULTS: We conducted a systematic search in ClinicalTrials.gov, Cochrane, Embase, PubMed, Google Scholar, and most relevant bariatric and heart failure journals. We extracted baseline and outcome individual participant data for every ventricular assist device patient undergoing BS with reported postoperative BMI and their respective timepoints when BMI data were measured. Fourteen references with 29 patients were included. The mean age was 41.9 ± 12.2 years, 82.8% underwent laparoscopic sleeve gastrectomy, and 39.3% had reported perioperative adverse events. The mean pre-BS BMI was 45.5 ± 6.6 kg/m2 and decreased significantly during follow-up (rho -0.671; P< .00001). Among 23 patients with documented listing status, 78.3% were listed for HT. Thirteen of 28 patients (46.4%) underwent HT at 14.4 ± 7.0 months. There were no reported deaths for the HT-free 1-year period. Median follow-up was 24 months (interquartile range, 12-30 months). Twenty-two of 28 patients (78.6%) achieved the composite outcome (BMI of<35 kg/m2/HT/listing for HT/myocardial recovery) at 11 months (interquartile range, 3-17 months). Patients with a BMI<45 kg/m2 had a higher chance of achieving the composite outcome (P< .003). CONCLUSIONS: BS may help patients with obesity and ventricular assist devices to lose a significant amount of weight and improve their candidacy for HT or even achieve myocardial recovery.

Bariatric surgery in obese patients with ventricular assist devices.

OBJECTIVES: Patients with end-stage heart failure (ESHF) treated with ventricular assist devices (VADs) tend to gain weight, which may prevent them from receiving heart transplantation (HT) if their body mass index (BMI) reaches ≥ 35 kg/m2. The objective was to synthesize all cases available in the literature and describe the most important outcomes of bariatric surgery (BS) in VAD patients, including BMI trends, reaching a BMI < 35 kg/m2, listing for HT, achieving HT, myocardial recovery, and mortality. These data were obtained for an individual participant data (IPD) meta-analysis and include available IPD for every case in the scientific literature describing VAD patients undergoing BS during VAD support with documented postoperative BMI (and time of measurement) during follow-up. DATA DESCRIPTION: These data include baseline, periprocedural, and long-term outcomes for the 29 patients meeting selection criteria. The composite outcome includes reaching a BMI < 35 kg/m2, listing for HT, receiving HT, and myocardial recovery, indicating significant BMI loss associated with major ESHF outcomes. As multiple centers are becoming more experienced in this field, the present data can be merged with their databases to form larger samples that will allow to perform further statistical analysis to identify outcome predictors and improve clinical protocols and outcomes.

Intussuscepted Metachronous small bowel tumor after treatment for colorectal adenocarcinoma.

INTRODUCTION: Small Bowel adenocarcinoma (SBA) is a rare malignant neoplasm without specific signs or symptoms. It's been associated with late stage disease presentations. Midterm outcomes have suggested that after successful removal of colorectal carcinoma, there is higher risk for developing a further primary (metachronous) colorectal tumor. However when it comes to small bowel, metachronous carcinomas are unusual. CASE PRESENTATION: A 46-year-old female who underwent an emergency Hartmann's procedure two years previously and treatment of adjuvant chemotherapy for adenocarcinoma of the sigmoid colon at stage IIB with loco-regional recurrence. The patient presented with bowel obstruction secondary to a small bowel intussusception, confirmed by computed tomography. An emergent exploratory laparotomy was performed and confirmed of an ileal tumor as the cause of small bowel intussusception and clinical bowel obstruction. Histopathology confirmed a primary small bowel mucinous adenocarcinoma with node metastasis (T3N1M0, stage IIIB). DISCUSSION AND CONCLUSION: Patients who develop a small or large bowel adenocarcinoma have high risk of presenting a second tumor at both sites. Since data available to guide therapeutic decisions for patients presenting with small bowel metachronic tumors are scarce, the role of adjuvant therapy in patients who undergo curative resection remains unclear. The aim of this manuscript is present a case report of a patient admitted for a rare obstructive small bowel intussusception therefore underwent surgery for metachronic small bowel carcinoma from colorectal primary witch previously treated by surgery and adjuvant chemiotherapy. Studies about strategies for detection at an earlier stage, optimal treatment and prognosis are mandatory for this disease.

Metástasis mamaria de linfoma de células del manto / Mammary metastasis of mantle cell lymphoma

Resumen ANTECEDENTES: Los linfomas mamarios primarios constituyen menos de 1% de todos los linfomas no-Hodgkin, 1.7-2.2% de todos los linfomas no-Hodgkin nodales adicionales y 0.04-0.5% de todas las neoplasias malignas de la mama. El linfoma de células del manto representa 4% de los linfomas en Estados Unidos, y entre 7-9% en Europa y se diagnostica en pacientes con una mediana de edad de 60 años. Aparece en mujeres posmenopáusicas en forma de masa mamaria indolora, unilateral. El linfoma de mama secundario es sistémico, con afectación simultánea o posterior en otro sitio. CASO CLÍNICO: Paciente con una tumoración mamaria, inicialmente postraumática, que en el contexto de plaquetopenia se catalogó clínica y radiológicamente como hematoma y que, más tarde, el diagnóstico fue: linfoma de células del manto secundario a linfoma previo nodal inguinal en segunda línea de tratamiento con quimioterapia. CONCLUSIONES: La persistencia o el rápido crecimiento de un hematoma mamario o de una lesión con apariencia radiológica benigna, sobre todo con antecedente de linfoma previo, puede resultar maligna. La biopsia mediante aguja gruesa es decisiva en el diagnóstico porque permite el estudio histológico e inmunohistoquímico para la confirmación molecular. El tratamiento se basa, sobre todo, en quimio y radioterapia, opciones que mejoran la supervivencia y disminuyen la recurrencia.

Abstract BACKGROUND: Primary mammary lymphomas represent less than 1% of all Non Hodgking Lymphomas (NHL). Mantle cell lymphoma (MCL) represents 4% of lymphomas in the United States, and 7-9% in Europe and is diagnosed in patients with a median age of 60 years. Unilateral painless mammary mass in postmenopausal women use to be the clinical presentation. Secondary breast lymphoma is defined as the presence of systemic lymphoma with breast involvement, as the patient below. CLINICAL CASE: 57-year-old female patient with post-traumatic mammary tumor, with history of thrombocytopenia, first-time diagnosed of hematoma, with breast enlargement and later diagnosed as lymphoma of mantle cells with pathology test and classified as secondary to previous inguinal nodal lymphoma. CONCLUSIONS: It is important to keep in mind this diagnosis in view of the persistence or rapid growth of a mammary hematoma or other lesion with benign radiological appearance. The biopsy is the gold standard for diagnosis, since it allows the histological and immunohistochemical study, for molecular confirmation. The treatment is mainly based on chemo / radiotherapy, which improves survival and decreases recurrence.

Mesenteric intranodal schwannoma: uncommon case of neurogenic benign tumor.

Intranodal schawnomas are extremely rare. Just a few cases have been described before. Clinical presentation comprises not only symptomatic mass in several anatomical body parts, but also, they can be found during analysis of surgical specimens resected for other reasons. The report is based on the case of an 80-year-old patient who underwent to right hemicolectomy for an adenocarcinoma. The histopathologic analysis revealed one mesenteric intranodal schwannoma in the surgical specimen. The diagnosis was confirmed by immunohistochemistry with positive result for vimentin and S100 protein. Less than 12 cases have been reported in the literature before. The findings pointed out our patient as, one of these few reported with such diagnosis.

Is the severe pain after Milligan-Morgan hemorrhoidectomy still currently remaining a major postoperative problem despite being one of the oldest surgical techniques described? A case series of 117 consecutive patients.

INTRODUCTION: Surgery is the only curative method of hemorrhoidal disease. Currently the Milligan-Morgan hemorrhoidectomy is still considered the "gold standard", since it is the best performing technique. However, postoperative pain remains a major problem. We analize the postoperative analgesic requirements for this procedure in 117 patients. PRESENTATION OF CASES: Between 2012 and 2013, 117 consecutive patients undergoing Milligan-Morgan hemorroidectomy, with an analysis of sex, age, total vascular anal cushions removed, hospital stay, complications, and relation with postoperative analgesic requirements. Patients with documented allergy to NSAIDs or pyrazolones were excluded. Additionally 23 patients undergoing Milligan-Morgan hemorrhoidectomy associated to internal lateral sphincterotomy were also analyzed. RESULTS: The mean age of patients was 51.7 years. The 50.8% were women and 49.2% men. In 33.3% of cases, one vascular anal cushion was removed, 2 in 39.3%, and 3 in 27.4%. The average stay for the 3 groups was 2.0days. An analgesic dose average of 4.1 by day was given, with opioid requirements in 22.2% of cases. It was statistically significant that as more anal cushions were eliminated was higher the opioids need. No significant difference of opioids use was found regarding patients undergoing sphincterotomy as additional procedure. DISCUSSION: Postoperative pain after a Milligan-Morgan hemorrhoidectomy currently remains a problem for colorectal surgery teams. This involves the use of opioids comparable to other major surgeries, finally causing not negligible days of admission charge. A protocolized analgesic treatment, as we actually do in our center, should be implemented after a Milligan-Morgan hemorrhoidectomy for improving the postoperative period pain management.

Perforated Meckel's diverticulum containing a carcinoid tumor successfully treated by the laparoscopic approach: Case report.

Mekel's diverticulum is a gastrointestinal malformation. Occurs in one of every 40 patients. It is usually asymptomatic whereas complications can be developed in 2% to 4%. The report is based on a 41-year old male, who attended to emergency, complaining of right lower quadrant abdominal pain. Blood tests showed high level of inflammatory markers. With acute appendicitis as presumptive diagnosis, laparoscopy was performed. The intraoperative findings were: a perforated Mekel's diverticulum with normal cecal appendix. Mechanical diverticular resection was made. The patient was successfully recovered from surgery. Histopathology examination showed: Meckel's diverticulum perforated with acute inflammation and neuroendocrine tumor (G1) pT1. Mekel's diverticulum is rarely affected by inflammatory complications and just few cases are associated with tumors. However, has ever been described before, coexisting both situations, being our patient the first reported with this exceptional clinical presentation, and treated successfully by laparoscopic approach.

Endometriosis causing acute appendicitis complicated with hemoperitoneum.

Endometriosis is a painful disorder characterized by endometrial tissue outside the uterine cavity. It usually affects the pelvis, but in rare cases it might extend to other parts of the body. The report is based on a case of a 39-year-old woman, who presented symptoms of acute appendicitis and diagnosis confirmed with ultrasonography and a computed tomography scan procedures. Laparoscopic appendicectomy was performed. After entering the abdominal cavity, hemoperitoneum was discovered with no associated pelvic or abdominal lesions. Biopsy confirmed acute appendicitis with endometrial glands and stroma infiltrating its muscular tissue. Patient recovered without complications and was discharged 48 h after surgery. The appendix is rarely affected by endometrial infiltration. The literature describes an incidence of 0.8%, just a few cases have been associated with acute appendicitis; however, none of them are described to present hemoperitoneum, being our patient the first one reported with such complication.
