Robotic surgery in the management of synchronous esophageal and gastric perforation after endoscopic dilation.

Upper gastrointestinal perforation is a feared complication of diagnostic and therapeutic endoscopy, with an incidence of perforation between 0.3% and 5%. Even though is rare, the mortality rate can be as high as 40%. Currently, there is no consensus on the best therapeutic strategy and it usually depends on patient stability, the extent of perforation, time to diagnosis, surgeon experience and available resourcesWe present a case of a patient who presented to our institution to undergo an ambulatory oesophageal dilation. After dilation, the patient developed two full-thickness gastric perforations and a full-thickness oesophageal perforation without haemodynamic instability. All perforations were diagnosed and treated with a combination of intraoperative endoscopy and robotic surgery with excellent outcomes.We demonstrate that a robotic approach combined with intraoperative diagnostic endoscopy is a safe and feasible treatment option for esophageal and gastric perforations in a stable patient without large extraluminal contamination.

Type IV Mirizzi Syndrome: Brief Report and Review of Management Options.

Mirizzi syndrome is a rare complication of chronic calculous cholecystitis. Preoperative diagnosis is challenging due to the absence of pathognomonic signs and symptoms and low sensitivity rates of imaging tests. Historically, laparotomy has been the preferred choice of surgical management. Endoscopic and laparoscopic approaches have been increasingly described as diagnostic and therapeutic options for Mirizzi type I and II, but data is limited regarding the management of more complex cases. We describe a staged endoscopic and laparoscopic approach for the management of type IV Mirizzi syndrome and review the management options.

Robotic repair of incarcerated morgagni hernia in an adult on the acute care surgery service

INTRODUCTION: Morgagni hernia is a relatively uncommon anterior diaphragmatic defect, particularly in adults. We describe the case of a patient who presented with an incarcerated Morgagni hernia and was repaired by an Acute Care Surgery service. DESCRIPTION: The patient is a 29 year old male who presented with a picture of bowel obstruction. CT scan revealed a Morgagni hernia with incarcerated stomach and colon. He was taken to the operating room for robotic repair. The hernia was reduced. The defect measured 10 x 7cm, a composite mesh was interposed, and sutured in place. The patient was discharged on postoperative day 5 and has done well at 1 year follow up. CONCLUSION: Robotic surgery offer the chance to apply minimally invasive techniques for urgent surgical care. This is the first reported case of an incarcerated Morgagni hernia repaired urgently using robotic techniques, and performed by acute care surgeons.

Introducción: La hernia de Morgagni es un defecto diafragmático, infrecuente en adultos. Aquí describimos el caso de un paciente presentándose con una hernia de Morgagni atascada, reparada bajo el servicio de cirugía de urgencias. Descripción: Varón de 29 años quien se presentó con un cuadro de oclusión gastrointestinal. La tomografía demostró una hernia de Morgagni atascada conteniendo estómago y colon. Fue llevado al quirófano para reparación asistida por robot. Una vez reducida la hernia, el defecto midió 10 x 7 cm, se interpuso una malla compuesta. El paciente fue dado de alta al quinto día post-quirúrgico, y al año de seguimiento, continua sin inconvenientes. Conclusión: La cirugía robótica ofrece la ventaja de aplicar técnicas mini-invasivas en el tratamiento de urgencias quirúrgicas. Este es el primer caso reportado de una hernia de Morgagni atascada reparada de manera urgente utilizando tecnología robótica, por cirujanos de urgencias.

Initial management of esophageal anastomotic strictures after transhiatal esophagectomy for esophageal cancer with dilations up to 18-20 mm.

INTRODUCTION: Esophageal anastomotic stricture is a well-known complication after transhiatal esophagectomy (THE), but there is limited data regarding the initial management and subsequent outcomes after stricture dilation. There is concern that dilating to larger diameters upon the initial encounter, specifically with high-grade strictures, will lead to increased risk for complications. We therefore reviewed one surgeon's experience with esophageal dilations after THE and provided data and treatment recommendations based upon these findings. METHODS: A retrospective review of patients who underwent esophageal dilations ≥ 18 mm up to 20 mm after THE between 2006 and 2019 at our institution was performed. Patient demographics were n = 97, age = 70, 81 males. RESULTS: For all cases, the mean location, length, diameter of the stricture, and number of days from surgery and initial dilation were 20 cm, 1.9 cm, 6.7 mm, and 106 days, respectively. Most dilations (79%) occurred within 2 weeks to 3 months from surgery. 29.9% were dilated up to 18 mm, 10.3% were dilated up to 19 mm, and 59.8% were dilated up to 20 mm upon initial dilation. Even 1-mm-diameter lesions could be safely dilated upon 18-20 mm. In this study group there were no complications after endoscopic dilation that required hospitalization or further surgical or endoscopic interventions. CONCLUSION: These results suggest that early aggressive endoscopic management of esophageal anastomotic strictures after THE can be safely performed.

Laparoscopic sleeve gastrectomy for giant gastric lipoma in morbid obese patient.

ANTECEDENTES: Los lipomas gástricos corresponden al 5% de los lipomas gastrointestinales. Muchos de ellos son solitarios, pequeños y asintomáticos, pero también pueden ocasionar síntomas obstructivos y sangrados. El tratamiento estándar es quirúrgico. CASO CLÍNICO: Mujer de 50 años con antecedente de obesidad mórbida, índice de masa corporal de 47.4 kg/m2, que se presenta con síntomas de epigastralgia y anemia. Se diagnostica un lipoma gástrico de 6.3 cm mediante tomografía y se confirma por biopsia endoscópica. DISCUSIÓN: La paciente fue exitosamente tratada a través de gastrectomía laparoscópica en manga. CONCLUSIÓN: La gastrectomía laparoscópica en manga es el procedimiento de elección para el tratamiento de los lipomas gástricos gigantes en los pacientes con obesidad mórbida cuando la anatomía lo permite. BACKGROUND: Gastric lipomas account for 5% of all gastrointestinal lipomas. Most of them are solitary, small and asymptomatic, however, they can cause severe symptoms such as obstruction, bleeding and intussusception. The standard treatment is surgical resection. CASE REPORT: 50 years old female with history of morbid obesity with a body mass index (BMI) of 47.4 Kg/m2, who presented with symptoms of epigastric pain and anemia. CT scan of the abdomen revealed a 6.3 cm gastric lipoma, confirmed by endoscopic biopsy. DISCUSSION: Laparoscopic sleeve gastrectomy is the procedure of choice for the excision of giant gastric lipomas in the morbidly obese, when anatomically feasible.

Magnetic sphincter augmentation: a viable rescue therapy for symptomatic reflux following bariatric surgery.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are commonly performed bariatric procedures in obesity management. Gastroesophageal reflux disease (GERD) in this population has reported rates of 23-100%. GERD after LSG has been noted with recent studies demonstrating de novo reflux or symptom exacerbation despite weight loss. Fundoplication is not an option, and medically refractory GERD after LSG is usually treated with conversion to RYGB. GERD post-RYGB is a unique entity, and management poses a clinical and technical challenge. We evaluate safety and effectiveness of magnetic sphincter augmentation after bariatric surgery. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was performed identifying patients that underwent LINX placement for refractory GERD after LSG, LRYGB, or duodenal switch across three institutions. Outcomes included complications, length of stay, PPI use, GERD-HRQL scores, and patient overall satisfaction. RESULTS: From March 2014 through June 2018, 13 identified patients underwent LINX placement after bariatric surgery: 8 LSG, 4 LRYGB, and 1 duodenal switch. The patients were 77% female, with mean age 43 and average BMI 30.1. Average pre-operative DeMeester score was 24.8. Pre-operatively, 5 patients were on daily PPI, 6 on BID PPI, and 1 on PPI + H2 blocker. We noted decreased medication usage post-operatively, with 4 patients taking daily PPI, and 9 off medication completely. A GERD-HRQL score was obtained pre- and post-operatively in 6 patients with average reduction from 25 to 8.5 (p value 0.002). Two patients experienced complications requiring endoscopic dilation after LINX placement. 100% of patients reported overall satisfaction post procedure. CONCLUSION: LINX placement is a safe, effective treatment option for surgical management of refractory GERD after bariatric surgery. It can relieve symptoms and obviate the requirement of high-dose medical management. Magnetic lower esophageal sphincter augmentation should be another tool in the surgeon's toolbox for managing reflux after bariatric surgery in select patients.

Paraesophageal hernia repair: a curative consideration for chronic anemia?

INTRODUCTION: Chronic anemia is a common, coinciding or presenting diagnosis in patients with paraesophageal hernia (PEH). Presence of endoscopically identified ulcerations frequently prompts surgical consultation in the otherwise asymptomatic patient with anemia. Rates of anemia resolution following paraesophageal hernia repair (PEHR) often exceed the prevalence of such lesions in the study population. A defined algorithm remains elusive. This study aims to characterize resolution of anemia after PEHR with respect to endoscopic diagnosis. MATERIALS AND METHODS: Retrospective review of a prospectively maintained database of patients with PEH and anemia undergoing PEHR from 2007 to 2018 was performed. Anemia was determined by preoperative labs: Hgb < 12 mg/dl in females, Hgb < 13 mg/dl in males, or patients with ongoing iron supplementation. Improvement of post-operative anemia was assessed by post-operative hemoglobin values and continued necessity of iron supplementation. RESULTS: Among 56 identified patients, 45 were female (80.4%). Forty patients (71.4%) were anemic by hemoglobin value, 16 patients (28.6%) required iron supplementation. Mean age was 65.1 years, with mean BMI of 27.7 kg/m2. One case was a Type IV PEH and the rest Type III. 32 (64.0%) had potential source of anemia: 16 (32.0%) Cameron lesions, 6 (12.0%) gastric ulcers, 12 (24.0%) gastritis. 10 (20.0%) had esophagitis and 4 (8%) Barrett's esophagus. 18 (36%) PEH patients had normal preoperative EGD. Median follow-up was 160 days. Anemia resolution occurred in 46.4% of patients. Of the 16 patients with pre-procedure Cameron lesions, 10 (63%) had resolution of anemia. Patients with esophagitis did not achieve resolution. 72.2% (13/18) of patients with no lesions on EGD had anemia resolution (p = 0.03). CONCLUSION: Patients with PEH and identifiable ulcerations showed 50% resolution of anemia after hernia repair. Patients without identifiable lesions on endoscopy demonstrated statistically significant resolution of anemia in 72.2% of cases. Anemia associated with PEH adds an indication for surgical repair with curative intent.

Atropine: A Cure for Persistent Post Laparoscopic Pyloromyotomy Emesis?

BACKGROUND: Atropine has been used as a successful primary medical treatment for hypertrophic pyloric stenosis. Several authors have reported a higher rate of incomplete pyloromyotomy with the laparoscopic approach compared to open. In this study, we evaluated the use of atropine as a medical treatment for infants with emesis persisting greater than 48 hours after a laparoscopic pyloromyotomy. MATERIALS AND METHODS: We performed a retrospective chart review of infants receiving a laparoscopic pyloromyotomy between November 1998 and November 2012. Infants with emesis that persisted beyond 48 hours postoperatively were given 0.01mg/kg of oral atropine 10 minutes prior to feeding. Infants remained inpatient until they tolerated two consecutive feedings without emesis. RESULTS: 965 patients underwent laparoscopic pyloromyotomy; 816 (84.6%) male and 149 (15.4%) female. Twenty-four (2.5%) received oral atropine. The mean length of stay for patients who received atropine was 5.6 ± 2.6 days, an average of 3 additional days. They were discharged home with a one-month supply of oral atropine. Follow up evaluation did not reveal any complications from receiving atropine. The median follow up was 21 days. None returned to the operating room for incomplete pyloromyotomy. There were 17 (1.8%) operative complications in our series; 9 mucosal perforations, 2 duodenal perforations, and 6 conversions to open for equipment failure or poor exposure. There were 4 (0.4%) post-operative complications: 2 episodes of apnea requiring reintubation and 2 incisional hernias that required a second operation. There were no deaths. CONCLUSION: Oral atropine is a viable treatment for persistent emesis after a pyloromyotomy and reduces the need for a second operation due to incomplete pyloromyotomy.

Blunt Traumatic Occlusion of the Common Iliac Artery Repaired With Segmental Excision and Internal Iliac Artery Patch Angioplasty.

Common iliac artery (CIA) occlusion as a result of blunt trauma is rare and seldom reported. This has been associated with pelvic fractures and other great vessel lesions. Management options include endovascular covered stent placement, open anatomic repair with autogenous conduit, or open extra-anatomic repair with prosthetic material. We report the case of a middle-aged male with a right CIA injury secondary to blunt trauma who underwent a successful repair using an internal iliac artery patch for injury to a 2 cm segment of CIA with peritoneal contamination. There is no definitively superior method to address CIA injuries in this setting reported in the literature. The use of the internal iliac artery as a patch can be regarded as an additional safe repair option when an autogenous repair is required for a large defect in the CIA as this can enable mobilization of the vessel for primary repair and offer a source for an autogenous patch.

Diffuse hepatic epithelioid hemangioendothelioma developed in a patient with hepatitis C cirrhosis.

Hepatic epithelioid hemangioendothelioma (HEHE) is an infrequent vascular tumor of endothelial origin that primarily occurs in women in the mid-fifth decade of life without underlying chronic liver disease or cirrhosis. Liver transplant should be the first-line of therapy in patients with large or diffuse unresectable tumors even in the presence of metastatic disease due to the favorable long-term outcome. We report the case of a 48-year-old female who complained of abdominal pain and weight loss. She has a history of cirrhosis secondary to chronic hepatitis C (HCV) and was treated with interferon and ribavirin with sustained virological response. Her work-up revealed multiple confluent infiltrating bilobar liver masses diagnosed as HEHE. She underwent a successful liver transplant without evidence of recurrent HCV infection. She developed cervical spine (C4-C6) HEHE metastases 4 years after transplant. She underwent surgical resection and local radiotherapy after resection with good clinical response. To the best of our knowledge, this is the first report of HEHE that developed in a patient with HCV cirrhosis successfully treated with antiviral therapy before transplant and liver transplant with good allograft function without evidence of recurrent liver tumor or HCV infection but developed metastases to the cervical spine 4 years after transplant.

Outcomes in the management of appendicitis and cholecystitis in the setting of a new acute care surgery service model: impact on timing and cost.

BACKGROUND: The acute care surgery model is a novel notion in the provision of emergency general surgery. To date, several studies have analyzed the effects on patient health outcomes and timeliness of care for nontrauma patients within the scope of acute general surgery and emergencies, but none have assessed the cost benefits of this model. STUDY DESIGN: A retrospective analysis of patients undergoing appendectomy or cholecystectomy in the setting of acute abdomen was performed to compare data from 2 cohorts, the traditional model from July 2009 to June 2010 and the acute care surgery model from July 2010 to June 2011. Categorical variables and comparison means were examined using chi-square and independent 2-tailed sample t-tests. RESULTS: One hundred and seventy-five patients underwent appendectomy and 113 underwent cholecystectomy. The traditional model team staffed 82 appendectomies and 51 cholecystectomies, and the acute care surgery team staffed 93 and 62, respectively. In the appendectomy group, there was a statistically significant mean reduction of time to surgical evaluation (2.19 hours; p < 0.001) and time to the operating room (5.38 hours, p = 0.006), there were 7 fewer patients with complications (p = 0.06) and a reduced length of stay (1 day, p = 0.002) for the acute care surgery cohort. Similar statistically significant differences were observed in the cholecystectomy group in the acute care surgery cohort: surgical evaluation difference = 5.84 hours (p = 0.03), time to operating room difference = 25.37 hours (p = 0.002), 8 fewer patients with complications (p = 0.01), and length of stay difference was 2 days (p = 0.03) compared with the traditional model cohort. CONCLUSIONS: The newly implemented acute care surgery model in our institution accomplished earlier treatment and shorter length of stay for the 2 most common causes of acute abdomen in our setting. Overall, the new model translated to better outcomes for patients and savings per case for the hospital.
