Sleeve Gastrectomy: Complications and Management

SLEEVE GASTRECTOMY COMPLICATIONS_REVIEW ARTICLE


Obesity is a common disease affecting adults and children. The incidence of obesity in worldwide is increasing. Laparoscopic sleeve gastrectomy (LSG) is a relatively new and effective procedure for weight loss. Owing to an increase in the number of bariatric surgical procedures, general surgeons should have an understanding of the complications associated with LSG and an approach for dealing with them. Early postoperative complications following LSG that need to be identified urgently include bleeding, staple line leak and development of an abscess. Delayed complications include strictures, nutritional deficiencies and gastresophageal reflux disease. We discuss the principles involved in the management of each complication.

COMO PODEMOS CURAR A MEDICINA ? (Atul Gawande)

“Nos últimos anos percebemos que estávamos na mais profunda crise da existência da medicina, devido a algo sobre o que você normalmente não pensa quando você é um médico preocupado em fazer o bem para as pessoas, que é o custo do tratamento de saúde. Não há um país no mundo que não esteja perguntando agora se podemos custear o que médicos fazem. A luta política que desenvolvemos tornou-se aquela sobre se o governo é o problema ou se as companhias de seguro são o problema. E a resposta é sim e não; é mais profundo que tudo isso. A causa de nossos problemas é, na verdade, a complexidade que a ciência nos deu. E para entender isso, voltarei algumas gerações…”

PERIOPERATIVE FLUID MANAGEMENT IN SURGERY

REVIEW ARTICLE_FLUID MANAGEMENT IN ELECTIVE SURGERY


The purpose of the thesis was to investigate the pathophysiology and functional outcomes of various fluid administration regimens in elective surgical procedures and describe factors of importance in perioperative fluid management. The goal was to create a rational physiologic background on which to design future ran-domized, clinical trials focusing on clinical outcomes aiming to produce evidence-based guidelines for rational perioperative fluid therapy. The main hypothesis of the thesis was thatthe ”liberal” fluid administration regimens seen in daily clinical practice may be detrimental and contribute to increased perioperative morbid-ity primarily due to increased functional demands of the cardi-opulmonary system and gastrointestinal tract as well as de-creased tissue oxygenation (impaired wound healing).

CIRURGIA: PASSADO, PRESENTE e FUTURO ROBÓTICO (Catherine Mohr)


A cirurgiã e inventora Catherine Mohr nos guia pela história da cirurgia (e seu passado pré-anestesia e pré-antissepsia), e depois demonstra algumas das mais novas ferramentas para cirurgias realizadas através de pequenas incisões, usando ágeis mãos robóticas.

EARLY COMPLICATIONS IN BARIATRIC SURGERY

REVIEW ARTICLE_BARIATRIC SURGERY COMPLICATIONS


ImagemThe risk of complications and mortality in bariatric surgery is associated with certain factors that are common to other patients and procedures, including age above 65 years, the presence of associated diseases (cardiovascular and pulmonary disease, chronic renal failure, liver cirrhosis, etc.), prior abdominal surgery, and the experience of the surgeon and the institution, especially concerning the ability to make an early diagnosis and address complications. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities (such as diabetes, arterial hypertension, and sleep apnea), as well as the difficulty in making an early diagnosis of the complications (due to limitations of the clinical abdominal workup and imaging methods, such as ultrasonography and computed tomography, particularly in highly obese patients with body mass indices >50 kg/m²), these patients require special attention in the early post operative follow-up. Pulmonary thromboembolism, a complication associated with bariatric surgery, also requires greater attention from the medical team given the high mortality rate associated with this condition. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control.

Princípios da Cirurgia HepatoBiliar


Considera-se que a cirurgia hepática começou após o advento da anestesia e da anti-sepsia. No entanto, muito antes disso, diversos autores já relatavam suas experiências com ressecções do fígado. As primeiras descrições de “cirurgias hepáticas” consistiam no relato de avulsões parciais ou totais de porções do fígado após lesões traumáticas do abdome. O relato de Elliot (1897) exemplifica muito dos temores dos cirurgiões da época: “O fígado (…) é tão friável, tão cheio de vasos e tão evidentemente impossível de ser suturado que parece ser improvável o manejo bem sucedido de grandes lesões de seu parênquima”.
