P-EGS24 Surgical case series of incarcerated diaphragmatic hernias following oesophagectomy for oesophageal cancer. Single centre experience

Background Incarcerated post-oesophagectomy diaphragmatic hernia (IPODH) is a recognised surgical emergency and potentially hazardous event. Information regarding the natural course for this emergency and guidelines regarding the management were not described clearly in literature. This case series aim to review patients who presented as emergency with IPODH Methods This observation study is conducted at Salford Royal Hospital that has one of the largest oesophago-gastric unit in United Kingdom. A 7-year period (April 2013 - April 2020) retrospective data collection is performed using prospectively maintained database. We reviewed the presentation and management course for all patients who presented as emergency with IPODH. Results We identified 341 patients who underwent oesophagectomies over the seven-year period. Seven patients (2%) developed IPODH which required emergency surgery. All these patients underwent 2 stage oesophagectomies. Out of these, 5 patients had laparoscopic assisted procedure (hybrid), 1 patient had minimally invasive procedure and another patient had open operation. Mean time interval from esophagectomy to the acute incarcerated hernia presentation was 23 months. Only 1 patient developed acute diaphragmatic hernia on day 4 post-oesophagectomy. The incarcerated hernia contents were reported as small bowels (4 patients), gastric conduit (2 patients) and colon (1 patient). Dealing with these acute emergency cases can be difficult as the hernia contents are threatened. Therefore, most of these patients underwent emergency laparotomy, only 1 patient had laparoscopic procedure to repair the incarcerated hernia. Collagen mesh used to repair the defect only in 2 patients, whereas the rest of the patients had the defect repaired with primary sutures only. Conclusions Minimally invasive techniques were associated with a higher incidence of post-oesophagectomy diaphragmatic hernia compared with open techniques. These hernias can lead to a significant and serious risk when they present with incarceration. The risk of the acute manifestation and significant post-repair morbidity support long-term surveillance for post-oesophagectomy diaphragmatic hernia and elective surgical treatment. Laparoscopic repair of non-complicated diaphragmatic hernia is feasible and effective in high-volume centres.

Intestinal obstruction after trauma laparotomy: a rare case due to colon cancer

The causes of intestinal obstruction are diverse with tissue adhesion, incarcerated hernia, and large bowel neoplasm being the most common causes. Cancer is not easy to diagnose in patients with a history of intestinal obstruction after the intraperitoneal operation following blunt trauma. Herein, we report the case of a patient who was diagnosed with colon cancer after undergoing adhesiolysis due to intestinal obstruction.

Tubo-Ovarian Inguinal Hernia with Ruptured Bleeding Follicle: A Case Report

Introduction: Hernias are abnormal protrusions of any abdominal-pelvic or fat organ, which are produced by a defect in the abdominal wall, the most frequent are inguinal hernias and their content is generally of the omentum or intestinal loops, the presence of pelvic organs is very infrequent and the majority of cases described are in children under five years of age. Objective: To analyze the entity in connection with a case of a patient with a tubo-ovarian inguinal hernia. Clinical case: The case of a 34-year-old female patient is presented, who was under follow-up by the gynecology service due to the presence of a left ovarian cyst, with symptoms of pain in the left iliac fossa for more than 6 months of evolution. which is performed an ultrasound, which reports left inguinal hernia for what is electively scheduled by the general surgery service, when performing the herniorrhaphy incarcerated hernia with left ovary with bleeding follicle and fallopian tube is evidenced. Conclusions: These types of findings are infrequent, documented in the literature with a global incidence of Tubo-ovarian inguinal hernias ranging from 0-8-4.4%, however it is worth clarifying that these studies are in infant patients, so its presentation in adults associated with a hemorrhagic follicle is anecdotal as in this case.

O33 TREATMENT OF INCARCERATED GROIN HERNIA - EMERGING EVIDENCE BASED ON THE SWEDISH HERNIA REGISTER

Aim The evidence base for statements about risk factors, morbidity and mortality for emergency hernia repair is mostly low quality. The aim of this study is to elucidate risk factors for the development of incarcerated hernia and outcome after adult emergency hernia repair using data from the Swedish Hernia Register (SHR). Material and Methods Data in this observational study were extracted from the SHR. It included registered cases between January 1, 2009 and December 31, 2019. Maximal follow-up was until December 31, 2020. Demographic data were analysed descriptively, risk analyses were performed using multivariate- and Cox-regression models. Results A total of 164.844 cases could be included after application of the in- and exclusion criteria. Women [odds ratio (OR) 1.42 99%CI 1.32–1.51], patients with lateral hernia [OR 1.54, 99%CI 1.47–1.61], femoral hernia [OR 14.63, 99%CI 13.32–16.06] and hernia recurrence [OR 2.46, 99%CI 2.33–2.60] were at higher risk of developing an incarcerated hernia. The highest strangulation risk was seen among women [OR 2.36, 99%CI 1.91–2.90], femoral hernia [OR 7.00, 99%CI 5.40–9.11] and recurrent hernia [1.90, 99%CI 1.54–2.33]. Patients with hernia incarceration or strangulation suffer significantly more frequent from postoperative complications [16.7% and 40.9% respectively, both p < 0.001]. Conclusions The data demonstrate that certain risks groups exist, which are prone to suffer from hernia incarceration and strangulation. These at risk patients should be prioritized, especially during the reorganisation of services to cope with the massive surgical backlog in the aftermath of the COVID-19 pandemic.

Assessment of bowel vascularity using indocyanine green fluorescence in incarcerated hernia

Intra-operative assessment of bowel vascularity is often needed during emergent surgery. An objective test to determine the viability could reduce postoperative ischemic complications. Indocyanine green dye has been used for assessing bowel vascularity in colorectal surgery. The following study involving two patients demonstrates its use for assessing the viability of bowel in obstructed hernias after intraoperative intravenous injection. Stryker 1588 AIM laparoscopic setup was used for intraoperative fluorescence. In both cases, dusky areas were noted over the obstructed bowel segment on visual inspection. However, satisfactory fluorescence was seen after dye injection, and hence mesh repair was done without resecting the bowel. All the patients had a good post-operative recovery. Indocyanine green fluorescence may be a good modality to intraoperatively assess bowel vascularity.

Evaluation of emergency general surgery operations in COVID-19 patients in a pandemic hospital: a single center experience

Background: During the pandemic, the decision on delaying elective surgeries was implemented country-wide, and emergency surgeries were excluded from this scope. In this study, the patients diagnosed with COVID-19 and who underwent an emergency general surgery operation were evaluated regarding indications, demographic characteristics, and preoperative and postoperative clinical features.Methods: In the study, emergency surgeries performed by the department of general surgery between 1st June and 30th September, when our center cared only patients diagnosed with COVID-19, were reviewed retrospectively.Results: A total of 13 patients, 7 women and 6 men, were included in this study. The most common surgical diagnosis was acute appendicitis (9/13). For all of the patients with appendicitis, a conventional appendectomy procedure was performed. 2 patients were diagnosed with an incarcerated femoral hernia and then operated (2/13). One patient was operated on due to a sharp object injury, and one due to an acute abdomen caused by a perforation. Only 3 of the operated patients developed postoperative wound site complications (23%). No mortality was observed by the end of a 15-day follow-up.Conclusions: The most common cause of emergency surgeries during the pandemic, changelessly, remains to be acute appendicitis. Besides, cases of trauma, perforated peptic ulcer, and incarcerated hernia are also commonly encountered. While the pandemic continues full steam, these conditions that are associated with the pandemic but among causes of mortality and morbidity other than COVID-19 and that may require an emergency surgery should be considered. All emergency surgical procedures should continue to be performed punctually by using necessary protective types of equipment.

Left-side incarcerated Amyand’s hernia with appendix and caecum provoke by early banana diet: a case report

Background Amyand’s hernia was an unusual condition defined by the presence of an appendix located in the inguinal hernia sac. Its prevalence was 1% of all inguinal hernia in children. The clinical manifestation of Amyand’s hernia was depending on hernia’s stage, an incarcerated hernia will present with an inguinal mass following by pain and motility disorder. It could lead to abdominal distention in the late stage. The common location of Amyand’s hernia was on the right side, the left side was uncommon. Early feeding on infants could provoke symptoms of bowel obstruction (SBO). More than 76% of infants in Java, Indonesia was given banana as solid food in infants before six months old. There is a correlation between the early banana diet and SBO. Amyand’s hernia could present as morbidity of early banana diet. Case presentation We describe a case of two months old infant present with an incarcerated left inguinal hernia and history of early banana diet that performed herniotomy procedure. During the operation, we found left-side incarcerated Amyand’s hernia with appendicitis, excoriation caecum, and sticky banana mass. Conclusion This case suggest the possibility of early feeding of banana diet may provoke incarceration of an inguinal hernia and if the incarcerated hernia content contains the appendix, then an Amyand's hernia.

8-mm portal incarcerated hernia after robotic colectomy: case report

Objective: The objective of this work is to report a hernia derived from the access portal used in robotic surgery. Details of the case: A 72-year-old woman, diagnosed with splenic angle adenocarcinoma of the colon, underwent robotic left colectomy and lymphadenectomy. On the 12th postoperative day, she developed vomiting and interrupted the elimination of feces and flatus. Computed tomography revealed hernia on the left flank with an 8 mm orifice with intestinal contents. Incisional herniorrhaphy was performed to correct the defect. PSH are associated with patient risk factors. They are also related to the diameter of the trocar and its place of passage. For its prevention, it is important to assess the need to close the aponeurosis according to each case. Final considerations: The disturbances created by the passage of 12 mm and 10 mm trocars must be closed. Those created by 5 mm trocars do not need to be closed, and those of 8 mm may or may not be closed, depending on the risk factors involved.
