Colonoscopy is a commonly performed endoscopic procedure. Although it is generally considered to be safe, serious complications, such as colorectal perforation, can occur. Most colonic perforations are intraperitoneal and cause pneumoperitoneum with acute abdominal pain as the initial symptom. However, extraperitoneal perforations with pneumoretroperitoneum may happen, albeit rarely, with atypical initial symptoms. We report a rare case of rectosigmoid perforation occurring after diagnostic colonoscopy that developed into pneumoretroperitoneum, pneumomediastinum, pneumothorax, and subcutaneous emphysema, with a change in voice and neck swelling as the initial symptoms...

Hepatic amino acid metabolism and protein secretion are essential liver functions that may be altered during metabolic stress, e.g. after surgery. We wished to develop a dynamic liver PET method using the radiolabeled amino acid (11)C-methionine to examine this question. Eleven 40-kg pigs were allocated to either laparotomy or pneumoperitoneum. 24 hours after surgery a 70-min dynamic PET scanning of the liver with arterial blood sampling was performed immediately after intravenous injection of (11)C-methionine...

Spontaneous neonatal gastric perforation is rare. We report the case of a newborn without any abnormality identified at delivery and whose mother had problem-free pregnancy. On the third day of life, he had a sudden onset of severe abdominal distension followed by bilious vomiting. Abdominal X-rays without treatment showed massive pneumoperitoneum and laparotomy showed a perforation at the level of the anterior gastric wall closed in a single layer closure. Postoperative course was uneventful. Spontaneous neonatal gastric perforation usually has a favorable outcome...

Laparoscopic surgery technology continues to advance. However, much less attention has been focused on how alteration of the laparoscopic surgical environment might improve clinical outcomes. We conducted a randomized, 2 × 2 factorial trial to evaluate whether low intraperitoneal pressure (IPP) (8 mmHg) and/or warmed, humidified CO2 (WH) gas are better for minimizing the adverse impact of a CO2 pneumoperitoneum on the peritoneal environment during laparoscopic surgery and for improving clinical outcomes compared to the standard IPP (12 mmHg) and/or cool and dry CO2 (CD) gas...

BACKGROUND: Prosthetic materials wrapped around a portion of the stomach have been used to provide gastric restriction in bariatric surgery for many years. Intraluminal erosion of adjustable and nonadjustable gastric bands typically occurs many years after placement and results in various symptoms. Endoscopic management of gastric band erosion has been described and allows for optimal patient outcomes. OBJECTIVES: We will describe our methods and experience with endoscopic management of intraluminal gastric band erosions after bariatric procedures...

INTRODUCTION: Creating pneumoperitoneum is the most challenging step during laparoscopy. The periumbilical area is the classic site for Veress needle insertion. We adopted a new access point for peritoneal insufflation. METHODS: We introduced a new point for Veress needle insertion to create pneumoperitoneum during difficult laparoscopic procedures. The needle is placed between the xiphoid process and the right costal margin, and it then proceeds toward the patient's right axilla...

Percutaneous image-guided ablation is performed throughout many areas of the body for various pathologies including hepatic malignancies. Heat and cold-based ablative technologies are effective and well-tolerated with an acceptable safety profile. However, ablative therapies may be technically more challenging and cause collateral thermal injury if the targeted lesion is adjacent to critical organs. Previously, techniques including artificial ascites and pneumoperitoneum have been utilized to displace or insulate critical structures from the ablation zone...

BACKGROUND: Chest X-ray (CXR) is a common imaging modality that could impact immediate decision-making for acute chest pathologies. We sought to examine the non-radiologists proficiency of diagnosing acute pathologies manifest on CXR. METHODS: We selected 9 clinical vignettes, each associated with a CXR, wherein only a single acute chest pathology was manifest. We also added a low-risk vignette associated with a normal CXR. We built an electronic survey with the CXR-embedded vignettes and also inquired about the participants' confidence in the diagnosis, and prior exposure to the topics...

Laparoscopy is one of the most common procedures performed worldwide .Over 50% of laparoscopic injuries to the gastrointestinal tract and major vessels occur during the initial entry phase. Major vascular injury during the initiation of a pneumoperitoneum is a much feared complication of laparoscopic procedures.This can be overcome by using a vacuum cup at the time of Veress entry especially in thin patients.The vacuum cup is a simple device to create pneumoperitoneum with ease . It can significantly reduce the risk of retroperitoneal injury associated with the use of Veress needle...

BACKGROUND: Patients with severe chronic obstructive pulmonary disease (COPD) are at a higher risk for postoperative respiratory complications. Despite the benefits of a minimally invasive approach, laparoscopic pneumoperitoneum can substantially reduce functional residual capacity and raise alveolar dead space, potentially increasing the risk of respiratory failure which may be poorly tolerated by COPD patients. This raises controversy as to whether open techniques should be preferentially employed in this population...

BACKGROUND: Pneumoperitoneum during laparoscopic cholecystectomy (LC) can cause hypercapnia, hypoxemia, hemodynamic changes and shoulder pain. General anesthesia (GA) enables the control of intraoperative pain and ventilation. The need for GA has been questioned by studies suggesting that neuraxial anesthesia (NA) is adequate for LC. STUDY OBJECTIVE: To quantify the prevalence of intraoperative pain and to verify whether evidence on the maintenance of ventilation, circulation and surgical anesthesia during NA compared with GA is consistent...

PURPOSE OF REVIEW: Gastric outlet obstruction (GOO) can result from benign and malignant causes. Until recently, surgical gastrojejunostomy was the treatment of choice for patient with benign and malignant GOO with a good functional status. Endoscopic placement of luminal self-expandable metal stents is currently widely accepted as the first line of treatment for malignant GOO because of its effectiveness and minimally invasive nature. The main shortcoming of luminal stents is the high incidence of recurrent GOO most commonly because of tumor ingrowth/overgrowth...

BACKGROUND: Robotic radical prostatectomy (RRP) is associated with various anesthetic challenges due to pneumoperitoneum and deep Trendelenburg position. Tenting of the abdominal wall done in RRP surgery causes decrease in peak airway pressure leading to better ventilation. Herein, we aimed to describe the effects of tenting of the abdominal wall on peak airway pressure in RRP surgery performed in deep Trendelenburg position. METHODS: One hundred patients admitted for RRP in Kokilaben Dhirubhai Ambani Hospital of American Society of Anesthesiologists 1 and 2 physical status were included in the study...
