Paracecal hernia with intestinal ischemia treated with laparoscopic assisted surgery

Unexpected right-sided sigmoid colon in laparoscopy: A case report and review of literature

BACKGROUND

The presence of a right-sided sigmoid colon is a rare anatomical variation usually discovered incidentally during surgical interventions. This case report details an unexpected right-sided sigmoid colon identified during a laparoscopic appendectomy and examines the pertinent literature to explore its clinical importance.

CASE SUMMARY

A 71-year-old woman presented with acute appendicitis. A preoperative computed tomography (CT) scan showed peri-appendiceal inflammation but no significant anatomical abnormalities. During laparoscopic surgery, an unexpected finding was encountered: The sigmoid colon was situated on the right side and exhibited an abnormal relationship with the cecum and ascending colon. Postoperative pathological examination confirmed appendicitis with no additional pathological findings. The right-sided sigmoid colon anomaly was verified through intraoperative assessment and later re-evaluation with CT and colonographic imaging. The patient underwent a laparoscopic appendectomy and experienced a smooth postoperative recovery.

CONCLUSION

This case highlights the necessity of being attentive to anatomical variations during laparoscopic surgery, particularly when managing appendicitis. A review of the literature indicated that the occurrence of a right-sided sigmoid colon is infrequent and may be associated with anomalies in midgut rotation during embryonic development. Awareness of this variation can help prevent surgical complications and inform future clinical practice.

Surgical Management of Pericaecal Hernia in a Virgin Abdomen

Internal hernia is an uncommon cause of mechanical small bowel obstruction. This case report details a 66-year-old Chinese male with no prior abdominal surgeries who presented with colicky abdominal pain, abdominal distension, and vomiting. Initial investigations were unyielding, but escalating symptoms prompted a diagnostic laparoscopy. Laparotomy then revealed a closed-loop obstruction through a lateral type pericecal hernia, with a segment of ischemic jejunum. Adhesion bands in the right iliac fossa and a congenital hernia orifice in the mesentery were identified and addressed. The patient recovered well postoperatively. This discussion explores the Meyer's classification of pericecal hernias, potential etiologies, clinical manifestations, diagnostic considerations, and the choice between laparoscopic and open surgeries. This case underscores the importance of a high index of suspicion, prompt surgical intervention, and the diagnostic utility of laparoscopy in managing pericecal hernias.

Laparoscopic Management of Para-Caecal Hernia With Small Bowel Obstruction: A Case Report

Para-caecal hernias are a rare type of internal hernias. They can cause bowel obstruction, leading to strangulation of the bowel. As such, urgent diagnosis and appropriate management are important. Both laparoscopic and open approaches are options in terms of surgical treatment. We report a case of a para-caecal hernia causing small bowel obstruction and highlight the laparoscopic approach as a feasible and effective way of management.

A spontaneous paracecal herniation: a rare form of an uncommon case

Paracecal hernias are a rare form of internal hernias. This is a case of a spontaneous paracecal retroperitoneal hernia in an elderly patient. A 73-year-old male, a known patient of adenocarcinoma of the rectum, who had undergone neoadjuvant radiotherapy and chemotherapy a year ago, presented with a 2-day-history of exacerbated colicky peri-umbilical and right-sided non-radiating abdominal pain, with associated progressive abdominal distension, which were aggravated by feeding. A contrasted abdominal computed tomography scan showed features of small bowel obstruction. An exploratory laparotomy revealed herniation of gangrenous small bowel ~30 cm through a small, tight opening just below the base of the cecum. Resection and anastomosis and closure of the retroperitoneal pouch were done. Patient recovered and was discharged on the fourth post-operative day. Spontaneous retroperitoneal hernias can occur in elderly patients with additional risk factors like neoplasms, with a high risk of bowel ischemia, hence the urgent need for surgical intervention.

Carcinoma located in a right-sided sigmoid colon: A case report

BACKGROUND

A right-sided sigmoid colon is an extremely rare anatomic variation that should be considered as a possibility by surgeons and radiologists before surgery. Here, we report the first clinical case of a carcinoma in a right-sided sigmoid colon revealed by a preoperative computed tomography (CT).

CASE SUMMARY

A 56-year-old Chinese man was admitted to the hospital with abdominal pain. CT revealed a redundant sigmoid colon with a mass on the right side of the cecum and ascending colon. Laparoscopy confirmed an abnormal course in the descending colon and sigmoid colon. Subsequently, hemicolectomy was performed in an open manner after laparoscopic exploration. Pathological examination revealed an infiltrative mucinous adenocarcinoma with two lymph node metastases. The patient was discharged without any complications after a week. There were no signs of recurrence or metastasis during the 3-month follow-up period.

CONCLUSION

We report a rare anomaly of a right-sided sigmoid colon with carcinoma, which should be differentiated from ascending colon cancer and pericecal hernia to prevent errors and other surgical complications.

Laparoscopic management of strangulated paracaecal hernia causing small bowel obstruction. Case report and review of the literature

Paracaecal hernia is a rare type of internal hernia usually presenting with a picture of small bowel obstruction. In this report we present a 68-year-old woman who was admitted with colicky lower abdominal pain, vomiting and abdominal distention. A computed tomography scan of her abdomen and pelvis demonstrated multiple dilated small bowel loops with a transition point in the right iliac fossa. After a trial of conservative treatment, the patient was taken to theatre where she underwent laparoscopic reduction of a strangulated paracaecal hernia. The patient had an uneventful post-operative recovery and was discharged home.

Despite being a rare cause for small intestinal obstruction, this should be part of the differential diagnosis especially in the absence of previous abdominal operations. Early recognition and prompt surgical treatment is the key to prevent complications. A laparoscopic approach is feasible if expertise is available.

Laparoscopic management of a small bowel obstruction caused by an unusual pericecal hernia: Case report

INTRODUCTION

Pericecal hernia is a rare type of internal hernia and may present with unspecific signs and symptoms. Thus, preoperative recognition of pericecal hernias can be challenging and difficult.

CASE PRESENTATION

We present a case of pericecal hernia in a rare location that was managed laparoscopically. A 63-year-old medically free gentleman presented to the emergency room with clinical and radiographic evidence of small bowel obstruction. An abdominal computed tomographic scan showed diffuse small bowel dilation and a transitional zone at the distal illeal loop near the ileocecal junction. The patient was admitted and started on conservative management. Two days later, there was no improvement in the patient's situation, and the patient underwent laparoscopic exploration where part of the distal ileum was seen going through a mesenteric defect superior to the ileocecal valve. The herniated bowel was reduced, and the hernia orifice was closed with sutures. The patient was discharged at day 9 postoperatively with excellent clinical and radiographic findings during the postoperative period.

DISCUSSION

Pericecal hernia in the superior ileocecal recess is the least common location for this type of hernia. Previously, laparoscopic management of small bowel obstruction was not recommended. However, recent evidence has shown excellent outcomes of laparoscopic management of pericecal hernia.

CONCLUSION

In pericecal hernia, having a high index of suspicion may help prevent delayed diagnosis and management. Laparoscopic exploration is a safe and acceptable modality for the diagnosis and treatment of small bowel obstruction due to pericecal hernias.

Paracecal hernia with intestinal obstruction managed with laparoscopic surgery: A case report

•

Paracecal hernia is a rare cause of intestinal obstruction.

•

Computed tomography can help in early diagnosis and avoidance of strangulation.

•

Laparoscopic surgery is a feasible alternative to open surgery for these cases.

Introduction

Paracecal hernia is a rare cause of intestinal obstruction.

Presentation of case

A 75-year-old man presented with abdominal pain for 4 days, vomiting, and obstipation. Physical examination was not conclusive. Abdominal radiograph suggested small intestinal obstruction, and computed tomography confirmed an obstructed paracecal hernia. Intraoperatively, the hernial sac was seen passing through the inferior ileocecal recess. The distal bowel was collapsed. The appendix was inflamed. The hernia was reduced and appendectomy was performed. The patient recovered without complications and was discharged on the fifth postoperative day.

Discussion

Internal hernia may be a cause of acute abdomen. Symptoms and signs may be nonspecific. Rapid recognition of the condition can prevent strangulation and ischemia of affected intestinal loops. Early resort to imaging examination will ensure quick diagnosis.

Conclusion

Paracecal hernia is a rare cause of intestinal obstruction. Awareness of the imaging features will help avoid delay in diagnosis. Laparoscopic surgery appears to be a safe and feasible treatment.

Hernia paracecal, reto diagnóstico y quirúrgico: reporte de caso y revisión de la literatura

Introducción. La hernia paracecal es una entidad rara que corresponde al 13 % de todas las hernias internas. Aunque algunas pueden ser adquiridas, la mayoría son congénitas y se originan en los recesos creados durante la adherencia y fusión de los repliegues peritoneales alrededor de la región ileocecal. Caso clínico. Se trata de un hombre de 42 años de edad a quien se le diagnosticó una apendicitis aguda. La intervención quirúrgica se inició con una incisión para apendicectomía localizada; no obstante, por los hallazgos intraoperatorios, se decidió la conversión a laparotomía y se produjo el hallazgo incidental de una hernia paracecal. Resultados. El paciente fue hospitalizado y, en el quinto día postoperatorio, presentó obstrucción intestinal por lo cual fue intervenido nuevamente; se encontró escaso líquido de reacción peritoneal y adherencias. Se le dio el egreso hospitalario cuatro días después de su último procedimiento quirúrgico y continuaba asintomático hasta su segundo control. Discusión. Las hernias paracecales son hernias internas que se describen como la protrusión de una víscera hueca por una apertura mesentérica o peritoneal. Sus manifestaciones clínicas son variadas y se puede presentar sin síntomas, con dolor abdominal localizado o hasta con obstrucción intestinal. El tratamiento quirúrgico se basa en liberar y examinar el segmento intestinal herniado y, de requerirse, proceder a la resección con anastomosis; se debe resecar el saco herniario cuando sea evidente, valorar los vasos mesentéricos y cerrar el defecto herniario. Se trata de una enfermedad poco común y es importante conocer su manejo con la finalidad de evitar complicaciones, ya que continúa siendo un reto diagnóstico para el cirujano.

Laparoscopic treatment of a pericaecal internal hernia

We present the case of a pericaecal hernia treated successfully with a laparoscopic approach and full recovery after surgery. A 53-year-old female patient with a personal history of depression, osteoporosis and irritable bowel syndrome consulted to the emergency department for abdominal pain and distension in the last 12 h, associated with one episode of vomit and diminished frequency in the passage of stools. The right abdomen was tender to palpation, and blood work revealed no leucocytosis. A computed tomography scan showed small bowel loops distended and displaced to the right parietocolic recess, lateral to the ascending colon. Exploratory laparoscopy was performed confirming the presence of small bowel loops incarcerated in the paracaecal fossa. These ones were reduced with gentle manoeuvres, and the peritoneal folds incised to prevent recurrence. The patient was started on an oral diet 2 days after surgery and discharged home on the 3^rd post-operative day.

Paracecal hernia due to membranous adhesion of the omentum to the right paracolic gutter

BACKGROUND

Paracecal hernias, also known as pericecal hernias, are an exceptionally rare type of internal hernia. We report a unique case of paracecal hernia due to membranous adhesion of the omentum to the right paracolic gutter.

CASE PRESENTATION

An 86-year-old female was admitted to our hospital with vomiting and abdominal pain. Laboratory findings showed a slightly elevated C-reactive protein level. Computed tomography scan showed dilated loops of the small intestine in the right paracolic gutter with medial displacement of the cecum and ascending colon. Internal hernia around the cecum due to postoperative adhesion after appendectomy was suspected, and she underwent emergency laparotomy. Intraoperative findings revealed the adhesion between the omentum and right paracolic gutter forming a cavity with the small intestine incarcerated. No abnormal adhesion in the ileocecal region was seen. We transected the omental adhesion from the orifice to the far end of the cavity near the hepatic flexure of the colon to release strangulation and to prevent recurrence. The patient was discharged on postoperative day 14 without complications.

CONCLUSIONS

Paracecal hernias have a type of membranous adhesion of the omentum to the right paracolic gutter. Surgeons should be aware of this paracecal hernia type, when they encounter the internal hernia.
