Subcutaneous emphysema of thorax, neck and face after elective left colectomy: A case report

INTRODUCTION Anastomotic leakage is a severe complication after colorectal surgery which causes substantial morbidity and mortality and impairs the oncologic and functional outcomes. The incidence rate varies in the literature from 4% to 26%. Diagnosis is difficult. Clinical presentation and time management are closely related to prognosis. If subcutaneous emphysema is an obvious clinical sign, its etiology is complex to determine, particularly in the post-operative course of colorectal surgery. PRESENTATION OF CASE We report our experience in the management of a patient with early colorectal anastomotic leakage after left colectomy, whose only physical sign was subcutaneous emphysema of thorax, neck and face. This presentation is not described to date. Emergency CT-scan with injection of contrast revealed a pneumoperitoneum with extradigestive air in the pelvis, pneumomediastinum and subcutaneous emphysema. Suture, drainage and defunctioning ileostomy have been performed in emergency with good results. The subcutaneous emphysema resolved spontaneously without specific treatment. DISCUSSION There are many differential diagnoses of subcutaneous emphysema and its etiology is potentially lethal. This case is original by the clinical manifestation of anastomotic leakage in the immediate post-operative course of colorectal surgery; this presentation is not described to date. CONCLUSION Isolated subcutaneous emphysema after left colectomy should suggest first a post-intubation tracheal wound. This case shows that an anastomotic leakage must be evocated and eliminated in order to provide the best outcome for these patients.

A retrospective multicenter analysis on redo-laparoscopic anti-reflux surgery: conservative or conversion fundoplication?

BackgroundNearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications. Furthermore, the optimal technique for redo-ARS remains debatable. The purpose of the current multicenter study was to review the outcomes of redo-fundoplication and to identify the best ARS repair technique for recurrent HH and gastroesophageal reflux disease (GERD).MethodsData on 975 consecutive patients undergoing hiatal hernia and GERD repair were retrospectively collected in five European high-volume centers. Patient data included demographics, BMI, techniques of the first and redo surgeries (mesh/type of ARS), perioperative morbidity, perioperative complications, duration of hospitalization, time to recurrence, and follow-up. We analyzed the independent risk factors associated with recurrent symptoms and complications during the last ARS. Statistical analysis was performed using GraphPad Prism® and R software®.ResultsSeventy-three (7.49%) patients underwent redo-ARS during the last decade; 71 (98%) of the surgeries were performed using a minimally invasive approach. Forty-two (57.5%) had conversion from Nissen to Toupet. In 17 (23.3%) patients, the initial Nissen fundoplication was conserved. The initial Toupet fundoplication was conserved in 9 (12.3%) patients, and 5 (6.9%) had conversion of Toupet to Nissen. Out of the 73 patients, 10 (13%) underwent more than one redo-ARS. At 8.5 (1–107) months of follow-up, patients who underwent reoperation with Toupet ARS were less symptomatic during the postoperative period compared to those who underwent Nissen fundoplication (p = 0.005, OR 0.038). Patients undergoing mesh repair during the redo-fundoplication (21%) were less symptomatic during the postoperative period (p = 0.020, OR 0.010). The overall rate of complications (Clavien-Dindo classification) after redo surgery was 11%. Multivariate analysis showed that the open approach (p = 0.036, OR 1.721), drain placement (p = 0.0388, OR 9.308), recurrence of dysphagia (p = 0.049, OR 8.411), and patient age (p = 0.0619, OR 1.111) were independent risk factors for complications during the last ARS.ConclusionsFailure of ARS rarely occurs in the hands of experienced surgeons. Redo-ARS is feasible using a minimally invasive approach. According to our study, in terms of recurrence of symptoms, Toupet fundoplication is a superior ARS technique compared to Nissen for redo-fundoplication. Therefore, Toupet fundoplication should be considered in redo interventions for patients who initially underwent ARS with Nissen fundoplication. Furthermore, mesh repair in reoperations has a positive impact on reducing the recurrence of symptoms postoperatively.

Embolisation portale préopératoire : présent et futur

Portal vein embolization consists of occluding a part of the portal venous system in order to achieve the hypertrophy of the non-embolized liver segments. This technique is used during the preoperative period of major liver resection when the future remnant liver (FRL) volume is insufficient, exposing to postoperative liver failure, main cause of death after major hepatectomy. Portal vein embolization indication depends on the FRL, commonly assessed by its volume. Nowadays, FRL function evaluation seems more relevant and can be measured by 99mTc labelled mebrofenin scintigraphy. Portal vein embolization procedure is mostly performed with percutaneous trans-hepatic access by using ultrasonography guidance and consists of embolic agent injection, such as cyanoacrylate, in the targeted portal vein branches with fluoroscopic guidance. It is a safe and well-tolerated technique, with extremely low morbi-mortality. Portal vein embolization leads to sufficient FRL hypertrophy in about 80% of patients, allowing them to undergo surgery from which they were initially rejected. The two main reasons of non-resection are tumor progression (≈15% of cases) and FRL insufficient hypertrophy (≈5% of cases). When portal vein embolization is not enough to obtain adequate FRL regeneration, hepatic vein embolization may potentiate its effect (liver venous deprivation technique).

Robotic Enucleation of an Esophageal Submucosal Tumor in the Prone Position

Background: Esophageal submucosal gastrointestinal stromal tumors (GISTs) are rare. Resection is indicated due to their malignant potential. Case Description: A 76-year-old woman complained of mild dysphagia. A submucosal tumor of the lower thoracic esophagus was found endoscopically. Computed tomography (CT) scan revealed a 40-mm anterolateral submucosal tumor. Endoscopic ultrasound revealed a hypoechoic and inhomogeneous lesion, developed from the fourth layer of the lower esophagus. In the prone position, the patient underwent robot-assisted right thoracoscopic enucleation of the esophageal submucosal tumor. The procedure was successfully completed with three trocars. No surgical complications occurred during the intervention or the postoperative stay. The patient was discharged on postoperative. Pathologic examination of the specimen revealed a GIST.
