Laparoscopic port site Richter's hernia - An important lesson learnt

Incarcerated Richter's congenital umbilical hernia in a young male: A case report

INTRODUCTION AND IMPORTANCE

Richter's hernia is a protrusion of a portion of the circumference of anti-mesenteric side of intestine through the fascial defect. It is a rare type of hernia and typically occurs in elderly patients. Richter's hernia could result in grave complications. The objective of the study was to describe a rare case of incarcerated Richter's congenital umbilical hernia in a 20-year-old male patient.

CASE PRESENTATION

A 20-year-old male presented with a complaint of intermittent crampy peri-umbilical pain of three days duration associated with non-reducible umbilical bulge and vomiting. On examination, there was 4 cm by 4 cm oval, firm, tender, non-reducible mass over the umbilical area without cough impulse. He was kept nothing per os, broad spectrum antibiotic started, consent taken & operated. A loop of the ilium which was mildly ischemic found in the hernia sac. Sac and entrapped intestine were thoroughly cleaned with warm saline and reduction and herniorrhaphy done. The client discharged on the 2nd postoperative day.

CLINICAL DISCUSSION

There have been very few reports of Richter's congenital umbilical hernia. Richter's hernia progresses more rapidly to gangrene than other strangulated hernias however patients often have no intestinal obstruction. Raised suspicion therefore is important to take timely surgical intervention before the disease advance and complications occurred.

CONCLUSION

Richter's hernia has subclinical symptoms and late presentation which could result in grave complications and increased mortality. The early decision for surgery has paramount importance in reducing complication and associated mortality.

Richter's Type Recurrent Indirect Inguinal Hernia, an Extremely Rare Occurrence: A Case Report

Background

Richter’s type recurrent indirect inguinal hernia remains to be an extremely rare entity reported scarcely. It may present with grave complications in the absence of symptoms and signs of intestinal obstruction. The aim of this study is to report a rare case of Richter’s hernia after a previously repaired indirect inguinal hernia.

Case Presentation

A 31-year-old male farmer came up with complaints of colicky abdominal pain and two episodes of vomiting. He had a previous right inguinal surgery. A physical examination revealed a full abdomen with right inguinal tenderness and oblique surgical scar. Abdominal ultrasound showed a bowel segment entrapped in the deep inguinal ring of the inguinal canal. Right inguinal exploration was done, and the finding was a gangrenous Richter’s type recurrent indirect inguinal hernia. The patient was discharged and improved on the seventh post-operative day after resection and anastomosis.

Discussion

Richter’s hernia is a rare form of hernia that occurs when the anti-mesenteric border of the bowel is partly trapped in a tight hernial ring. Its rarity, combined with the fact that it may present in the absence of typical symptoms and signs of intestinal obstruction and local physical findings, poses a diagnostic challenge which often end up with complications like gangrenous bowel at the time of diagnosis.

Conclusion

Richter’s hernia can occur in an extremely rare form as Richter’s type recurrent indirect inguinal hernia. A high degree of suspicion, an early referral and timely imaging on the provider's side may prevent mortality and morbidity.

Five-millimeter Trocar Site Hernia with a Parastomal Hernia Sac: A Case Report

Here, we report our experience with a 5-mm trocar site hernia (TSH) near a stoma. This is the first report describing the relationship between TSH and extraperitoneal colostomy. A 72-year-old man underwent laparoscopic abdominoperineal resection with extraperitoneal sigmoid colostomy and partial hepatectomy for rectal cancer accompanied by synchronous liver metastasis (pT3N1aM1a Stage IVA Union for International Cancer Control [UICC] 8th edition). The surgical procedures were completely performed without morbidity. After 1 year, he presented to our hospital with sudden nausea. Computed tomography (CT) revealed small bowel obstruction due to a 5-mm TSH, 1 cm from the stoma. The patient underwent laparoscopic hernia repair. The incidence of a 5-mm TSH is low. However, an abdominal wall vulnerability caused by the extensive exfoliation of the retroperitoneum due to the construction of the colostomy was observed, and the extraperitoneal colostomy influenced the onset of the 5-mm TSH. When the port and hernia sites are located in close proximity to each other, even a 5-mm trocar site may increase the incidence of TSH.

Richter-type Spigelian hernia: A case report and review of the literature

INTRODUCTION

Abdominal wall hernias through the arcuate line termed Spigelian hernias are uncommon. These hernias presenting as a Richter-type, with strangulation of part of the circumference of the bowel wall is very rare.

PRESENTATION OF CASE

We report a 27-year-old male patient who presented with a Richter-type Spigelian hernia.

LITERATURE REVIEW

A MEDLINE literature search of this rare entity yielded six publications presenting Richter-type Spigelian hernias. All of these articles and accompanying references were thoroughly reviewed. There was no gender or anatomical side predominance among the patients. All except our patient presented here were elderly. Pain was the most common symptom and was present in all patients. All patients underwent surgical repair and none reported recurrence of their hernia afterwards.

DISCUSSION AND CONCLUSION

Richter-type Spigelian hernia is rare and has been reported infrequently in the existing literature. Clinical diagnosis is challenging and CT scan is the diagnostic study of choice. Surgical repair is the definitive treatment and involves primary or mesh repair of the defect as appropriate. Necrotic bowel should be resected and we recommend biologic mesh repair in these cases if the defect is large.

Incarcerated Trocar Site Herniation of the Small Bowel following Laparoscopic Myomectomy

Small bowel herniation through the fascial defect created by the entry of trocars is one of the major complications of the laparoscopic surgery. In this paper, we describe a 42-year-old woman developing an incarcerated trocar site herniation of the small bowel following laparoscopic myomectomy and treated by laparoscopic approach.
