The role of minimally invasive hepatectomy for hilar and intrahepatic cholangiocarcinoma: A systematic review of the literature.

Despite the fact laparoscopic liver resections (LLR) for cholangiocarcinoma is still limited, this systematic review addressed surgical and oncological outcomes of LLR to treat both perihilar cholangiocarcinoma (pCCA) and intrahepatic cholangiocarcinoma (iCCA). Five comparative and 20 noncomparative studies were found. Regarding iCCA, LLR had lower blood loss and less need for Pringle maneuver. However, open liver resections (OLR) were performed more for major hepatectomies, with better lymphadenectomy rates and higher number of harvested lymph nodes. High heterogeneity and selection bias were suggested for iCCA studies.

An ERAS protocol for bariatric surgery: is it safe to discharge on post-operative day 1?

BACKGROUND: Laparoscopic sleeve gastrectomy is the most commonly performed bariatric surgery in the world. Enhanced recovery after surgery (ERAS) protocols have been shown to reduce complications and decrease length of stay for various types of surgeries. In this study, we propose an ERAS protocol for laparoscopic sleeve gastrectomy and compare the clinical outcomes with patients who received standard care. METHODS: We performed a single-institution retrospective analysis in patients who underwent laparoscopic sleeve gastrectomy from February 2015 to December 2017. Patients were stratified into standard care and ERAS protocol groups. The ERAS protocol consisted of goal-directed patient education, specific pre- and post-op multi-modal medication regimen, early ambulation, and early oral intake. Patients were discharged on their first post-operative day if they met appropriate post-surgical milestones. The primary outcomes were length of stay, 7- and 30-day readmission rates, and complication rates. Secondary outcomes included anti-emetic and pain medication utilization, post-operative emesis episodes per day, post-operative pain scores, and mortality. RESULTS: We included 214 consecutive patients who underwent sleeve gastrectomy, 130 were in the ERAS group and 84 were in the standard care group. Median hospital stay was significantly shorter in the ERAS group compared to the standard care group (1 vs. 2 days; p < 0.001). There were no differences in 7- or 30-day readmission rates (1.5 vs. 1.2%; p = 0.838, 2.3 vs. 2.4%; p = 0.966) or post-operative complications (6.2 vs. 3.6%; p = 0.410). The ERAS group also had decreased median intra-operative opioid consumption and self-reported pain scores on post-operative day 1 (27.5 MME vs. 27.4 MME; p = 0.044, 3.3 vs. 3.9; p = 0.046). Mortality rate was 0% overall. CONCLUSION: A cost-effective ERAS protocol for laparoscopic sleeve gastrectomy results in shorter length of stay, without increase in peri-operative morbidity or readmission rates.

Oncologic aspects of the decision-making process for surgical approach for colorectal liver metastases progressing during chemotherapy.

Colorectal cancer represents the third most diagnosed malignancy in the world. The liver is the main site of metastatic disease, affected in 30% of patients with newly diagnosed disease. Complete resection is considered the only potentially curative treatment for colorectal liver metastasis (CRLM), with a 5-year survival rate ranging from 35% to 58%. However, up to 80% of patients have initially unresectable disease, due to extrahepatic disease or bilobar multiple liver nodules. The availability of increasingly effective systemic chemotherapy has contributed to converting patients with initially unresectable liver metastases to resectable disease, improving long-term outcomes, and accessing tumor biology. In recent years, response to preoperative systemic chemotherapy before liver resection has been established as a major prognostic factor. Some studies have demonstrated that patients with regression of hepatic metastases while on chemotherapy have improved outcomes when compared to patients with stabilization or progression of the disease. Even if disease progression during chemotherapy represents an independent negative prognostic factor, some patients may still benefit from surgery, given the role of this modality as the main treatment with curative intent for patients with CRLM. In selected cases, based on size, the number of lesions, and tumor markers, surgery may be offered despite the less favorable prognosis and as an option for non-chemo responders.

Brazilian-Portuguese Validation Assessment of the Gastrointestinal Quality of Life Index for Patients After Laparoendoscopic Cholecystectomy.

Background: Cholelithiasis is currently one of the most common diagnosis in Brazil. The aim of this study was to validate the Gastrointestinal Quality of Life Index (GIQLI) as a quality-of-life (QoL) assessment among the Brazilian population with syntomatic gallstone. Materials and Methods: The questionnaire was translated and culturally adapted after the linguistic validation process determined by the international methodology. Sixty-three patients who underwent laparoscopic cholecystectomy responded to the GIQLI-Brazil and Short-Form Health Survey (SF-36) instruments. For the evaluation of reproducibility, 30 patients responded to GIQLI-Brazil two more times after 2 and 4 weeks. After the University of São Paulo Ethics Commitee Board approval (UNIFESP/CEP: 1270/2019), the study was carryed out between May 2019 and February 2020 at the Gastroenterology outpatient clinic of Hospital São Paulo-Federal University of São Paulo (UNIFESP). Cronbach's alpha, the calculation of the intraclass correlation coefficient (ICC), and Spearman's correlation were used to assess the validity and reproducibility of the instrument translated into Portuguese, and to measure correlation between the domains of the GIQLI-Brazil and SF-36 (P < .05). Results: Seven questions were modified during the process of translation and cultural adaptation. The Brazilian version of the instrument presented a Cronbach's alpha of 0.89, and excellent reproducibility through the ICC, with the following variation between domains: meteorism (ICC = 0.918; P < .001) and gastrointestinal function (lower tract) (ICC = 0.956; P < .001). The dimensions of the GIQLI-Brazil and SF-36 demonstrated a significant correlation (P < .001), except between the domains: functional aspects of the SF-36 and gastrointestinal function (lower tract) of the GIQLI-Brazil (r = 0.211). Conclusion: The GIQLI was translated and validated for Portuguese-Brazil and can be used to assess the QoL of adult patients with gastrointestinal diseases and/or disorders.

Analysis of tissue inflammatory response, fibroplasia, and foreign body reaction between the polyglactin suture of abdominal aponeurosis in rats and the intraperitoneal implant of polypropylene, polypropylene/polyglecaprone and polyester/porcine collagen meshes.

PURPOSE: To compare tissue inflammatory response, foreign body reaction, fibroplasia, and proportion of type I/III collagen between closure of abdominal wall aponeurosis using polyglactin suture and intraperitoneal implant of polypropylene, polypropylene/polyglecaprone, and polyester/porcine collagen meshes to repair defects in the abdominal wall of rats. METHODS: Forty Wistar rats were placed in four groups, ten animals each, for the intraperitoneal implant of polypropylene, polypropylene/polyglecaprone, and polyester/porcine collagen meshes or suture with polyglactin (sham) after creation of defect in the abdominal wall. Twenty-one days later, histological analysis was performed after staining with hematoxylin-eosin and picrosirius red. RESULTS: The groups with meshes had a higher inflammation score (p < 0.05) and higher number of gigantocytes (p < 0.05) than the sham group, which had a better fibroplasia with a higher proportion of type I/III collagen than the tissue separating meshes (p < 0.05). There were no statistically significant differences between the three groups with meshes. CONCLUSIONS: The intraperitoneal implant of polypropylene/polyglecaprone and polyester/porcine collagen meshes determined a more intense tissue inflammatory response with exuberant foreign body reaction, immature fibroplasia and low tissue proportion of type I/III collagen compared to suture with polyglactin of abdominal aponeurosis. However, there were no significant differences in relation to the polypropylene mesh group.

Endoscopic transnasal approach for treatment of the medial orbital blowout fracture using nasal septum graft.

We present the experience of the Ear, Nose, and Throat Department of Santa Casa de Misericórdia de Curitiba and Hospital Universitário Cajuru PUC-PR in the transnasal endoscopic approach to medial orbital blowout fractures using nasal septum grafts. Seventeen patients have undergone endoscopic repair since June 2005, and septum grafts were used to maintain the orbital contents in position. All 17 patients were treated with this method. Two patients had diplopia on immediate postoperative evaluation. This symptom was corrected with orthoptic exercises in one patient, and the other had a little residual diplopia. Postoperative computed tomography scans showed anatomic reduction in 14 of 17 cases. There were no complications in these surgeries. The transnasal endoscopic approach is a reasonable method for the treatment of medial orbital blowout fractures. Use of septum graft is another surgical alternative for this technique.

Does mesenchymal stem cell improve the liver regeneration after the 70% hepatectomy?

PURPOSE:: To evaluate the effects of mesenchymal stem cells on liver regeneration in rats following a 70% hepatectomy. METHODS:: Forty rats were subjected to 70% hepatectomy and then ~106 mesenchymal stem cells (test group), or saline solution (control group), were infused into their livers via the portal vein. Each treatment group was divided into early and late subgroups (euthanized 3 d and 5 d following the operation, respectively). Group comparisons of Albumin, aminotransaminases (AST, ALT), and Alcaline Phosphatase (AP) levels, proliferative index (ki-67+ straining), and mitotic cell counts were conducted. RESULTS:: No significant differences in liver regeneration rate, number of mitoses, proliferative index, or serum levels of albumin, AST, or AP were observed. ALT levels were higher in the test group than in the control group (p<.05). CONCLUSIONS:: Mesenchymal stem-cell therapy did not improve liver regeneration rate 3 d or 5 d after 70% hepatectomy in rats. Likewise, the therapy appeared not to affect liver function, proliferative index, or number of mitoses significantly.

Comparative study of the effects of submucosal cauterization of the inferior turbinate with or without outfracture.

AIM: The objective of this study was to compare the effects of submucosal cauterization of the inferior turbinate with or without outfracture. STUDY DESIGN: Clinical prospective. METHOD: Twenty patients with inferior turbinate hypertrophy were randomized and divided into two groups. The first one was submitted to submucosal cauterization associated with outfracture, and the second one without fracture. Five items were assessed to compare both methods: pain, nasal bleeding, scarring--analyzed through anterior rhinoscopy, observing edema, hyperemia and seropurulent secretion; crust formation (seen through anterior rhinoscopy); and nasal airway patency. Follow-up was performed on days 7, 14, 30. RESULTS: In both groups crusting formation was similar. Scarring showed better results in the outfracture group in the first two weeks postoperative. The analysis of nasal airway patency showed good results in 80% of the patients submitted to submucosal cauterization with outfratcture on day 30 postoperatively. CONCLUSIONS: We concluded that submucosal cauterization of inferior turbinate with outfracture is better than the procedure without outfracture.

Experimental study on the effects of bismuth subgallate on the inflammatory process and angiogenesis of the oral mucosa.

INTRODUCTION: Bismuth subgallate is a salt derived from heavy metal. The aim of this study was to evaluate the effect of this salt on some phases of healing. OBJECTIVES: To assess the effect of subgallate on mucosa and to evaluate the association between the use of bismuth subgallate and neogenesis of vessels in oral mucosal wounds. METHODS: This was a prospective and experimental study. This study used sixty rats, which were divided into control and experimental groups. The animals were submitted to a surgical procedure, which caused oral mucosal injury. A saline solution was applied on the wound of the control group, and in the experimental group, a solution of bismuth subgallate was administrated. RESULTS: The experimental group showed greater inflammatory reaction with increasing monomorphic proliferation. There was increased vessel proliferation in the control group. CONCLUSION: Bismuth subgallate had a negative influence on the healing process, delaying the rate of new vessel formation and optimal wound healing.

Tratamento endoscópico de epistaxe proveniente da artéria etmoidal anterior: experiência do serviço de ORL da PUCPR / Endoscopic treatment of epistaxis from the anterior ethmoidal artery: ORL service experience at PUCPR

Introdução: A epistaxe grave é considerada a principal emergência na prática otorrinolaringológica e causa importante de internação hospitalar. O tratamento endoscópico nasal é mais bem tolerado pelos pacientes, uma vez que os tamponamentos nasais resultam em dor, obstrução nasal e morbidade significativa. O tratamento da epistaxe proveniente da artéria etmoidal anterior se tornou mais efetivo com o advento das técnicas de endoscopia nasal. Tradicionalmente, o controle do sangramento desse território era realizado através de uma incisão de Lynch no rebordo orbital medial e dissecção entre a periórbita e a lâmina papirácea, com ligadura ou cauterização da artéria etmoidal anterior. A abordagem endoscópica permite a localização mais precisa da origem do sangramento e um controle mais efetivo. Objetivo: Reportar a experiência do Serviço de Otorrinolaringologia da PUCPR no tratamento endoscópico da epistaxe proveniente da a.etmoidal anterior. Método: Entre Maio de 2005 e Dezembro de 2008 foram tratados endoscopicamente 10 pacientes apresentando epistaxe proveniente da a.etmoidal anterior. Todos os pacientes foram submetidos à dissecção do teto do etmoide com óptica de 45o e instrumental adequado. Conclusão: A abordagem endoscópica para o tratamento de epistaxe proveniente da artéria etmoidal anterior mostrou-se segura e eficaz nos casos apresentados.

Introduction: The severe epistaxis is considered to be the main emergency in the otorhinolaryngologic practice and causes important hospital interment. The nasal endoscopic treatment is best tolerated by the patients, since nasal splints result in pain, nasal obstruction and significant morbidity. The treatment of the epistaxis from the anterior ethmoidal artery became more effective with the advent of nasal endoscopy techniques. Traditionally, this territory bleeding control was made through Lynch's incision in the medial orbital border and dissection between the periorbital and papyraceous lamina, with connection or cauterization of the anterior ethmoidal artery. The endoscopic approach allows a more precise localization of the bleeding origin and a more effective control. Objective: To report the experience of the Otorhinolaryngology Service at PUCPR in the endoscopic treatment of the epistaxis resulting from the anterior ethmoidal artery. Method: Between May 2005 and December 2008, 10 patients who presented with anterior ethmoidal artery epistaxis were treated with endoscopy. All patients were submitted to the dissection of the ethmoid roof with optic of 45o and suitable instruments. Conclusion: The endoscopic approach for the treatment of epistaxis coming from anterior ethmoidal artery was proven to be safe and efficient in the cases presented.

Estudo comparativo de pacientes submetidos à cauterização submucosa com ou sem fratura lateral do corneto inferior / Comparative study of the effects of submucosal cauterization of the inferior turbinate with or without outfracture

OBJETIVO: Comparar os efeitos da cauterização submucosa do corneto inferior com e sem a fratura lateral. FORMA DE ESTUDO: Clínico prospectivo. MATERIAIS E MÉTODOS: Foram selecionados 20 pacientes aleatoriamente com diagnóstico de hipertrofia crônica dos cornetos nasais, e divididos em dois grupos. O primeiro foi submetido à cauterização submucosa com fratura lateral do corneto, e o segundo sem a fratura. Foram avaliados cinco quesitos, comparando-se os dois métodos: dor, sangramento nasal, cicatrização, formação de crostas e perviedade nasal. O seguimento pós-operatório foi realizado no 1°, 7°, 14° e 30° dias. RESULTADOS: Quanto à dor, sangramento nasal e formação de crostas o resultado foi semelhante para ambos os grupos. Em relação à cicatrização, houve melhores resultados no grupo submetido à fratura lateral nas primeiras duas semanas do seguimento. Quanto à perviedade nasal, 80 por cento dos pacientes submetidos à cauterização submucosa com a fratura lateral referiram boa perviedade. Por outro lado, 30 por cento dos pacientes não submetidos à fratura lateral relataram boa perviedade. CONCLUSÃO: A realização da cauterização submucosa do corneto inferior associada à fratura lateral é mais eficaz que a realização da cauterização isoladamente.

AIM: The objective of this study was to compare the effects of submucosal cauterization of the inferior turbinate with or without outfracture. STUDY DESIGN: clinical prospective. METHOD: Twenty patients with inferior turbinate hypertrophy were randomized and divided into two groups. The first one was submitted to submucosal cauterization associated with outfracture, and the second one without fracture. Five items were assessed to compare both methods: pain, nasal bleeding, scarring - analyzed through anterior rhinoscopy, observing edema, hyperemia and seropurulent secretion; crust formation (seen through anterior rhinoscopy); and nasal airway patency. Follow-up was performed on days 7, 14, 30. RESULTS: In both groups crusting formation was similar. Scarring showed better results in the outfracture group in the first two weeks postoperative. The analysis of nasal airway patency showed good results in 80 percent of the patients submitted to submucosal cauterization with outfratcture on day 30 postoperatively. CONCLUSIONS: We concluded that submucosal cauterization of inferior turbinate with outfracture is better than the procedure without outfracture.
