Spontaneous reduction of hernia "en masse"

A rare case of reduction en masse of incarcerated inguinal hernia: A case report

INTRODUCTION AND IMPORTANCE

Reduction en masse is a rare complication of incarcerated inguinal hernias, occurring when the herniated sac, along with the trapped hernia, returns to the preperitoneal space.

CASE PRESENTATION

In this study, we describe a 74-year-old male patient who presented to the hospital with a history of manual hernia reduction and complaints of nausea, vomiting, and constipation for two weeks. After undergoing paraclinical tests, he underwent open surgery with a diagnosis of hernia reduction en masse, during which the hernia sac was separated from the surrounding structures. Abdominal and peritoneal defects were also repaired intra-abdominally. After his condition stabilized, the patient was discharged with prescription medications.

DISCUSSION

Reduction en masse in inguinal hernia cases is rare, where the hernia sac and intestinal contents are reduced while the intestine remains incarcerated. Computed tomography (CT) scans can aid in diagnosis, revealing characteristic features such as closed-loop obstruction and inguinal soft tissue changes. Treatment options include open laparotomy and laparoscopy, with laparoscopy being preferred depending on surgeon expertise, assessment of intestinal viability post-reduction, and patient stability.

CONCLUSIONS

The potential complications of hernia reduction en masse should be emphasized to patients who choose not to remain under medical supervision, as well as to physicians and surgeons when patients re-present following manual hernia reduction. Increasing awareness about this condition at relevant times is crucial.

Is the Laparoscopic Approach Feasible for Reduction and Herniorrhaphy in Cases of Acutely Incarcerated/Strangulated Groin and Obturator Hernia?: 17-Year Experience from Open to Laparoscopic Approach

Purpose: Management strategies for acutely incarcerated/strangulated groin and obturator hernias may differ from institution to institution, although, conventionally, the open approach has been used. Recently, laparoscopic transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair have become commonly used operative procedures for the repair of groin hernias. It is unclear whether laparoscopic reduction and herniorrhaphy can be successfully accomplished in all cases. This study was aimed at assessing the effectiveness of laparoscopic treatment. Methods: We conducted a prospective clinical trial of the laparoscopic approach from December 2011 and comparatively analyzed the surgical outcomes between the open and laparoscopic approaches for incarcerated/strangulated hernias seen from December 2000 to March 2017. Results: The open approach for repair was used in 54 patients (50.9%) and the laparoscopic approach in 52 patients (49.1%). There was 1 case in which from the laparoscopic approach to laparotomy (1.9%) was required. The operation time treated by the laparoscopic approach was significantly longer than the open approach (126.4 minutes versus 104.6 minutes; P = .0079); however, the incidence of postoperative complications and the postoperative length of hospitalization were also less in the former group than in the latter group (3.9% versus 18.5%; P = .0172 and 5.6 days versus 14.7 days; P = .0096). Second-stage TAPP herniorrhaphy was performed in 7 patients (15.2%) after bowel resection or closure of bowel perforation, and first-stage TEP herniorrhaphy was performed in 1 patient after bowel resection. There was no case of mesh infection in the group treated by the laparoscopic approach, and there was 1 case of mesh infection in the group treated by the open approach. The mortality rate was 0% in the group treated by the laparoscopic approach. Conclusions: Laparoscopic reduction and herniorrhaphy for acutely incarcerated/strangulated groin and obturator hernias is effective, safe, and feasible.

Reduction en masse can be treated using pure laparoscopic transabdominal preperitoneal hernioplasty following early CT diagnosis: report of a case

Reduction en masse refers to the rare occurrence of an incarcerated inguinal hernia arising from the manual reduction of a hernia. Such a condition constitutes a medical emergency because the hernia contents, such as the small bowel, remain strangulated in the preperitoneal space. Therefore, an early and accurate diagnosis, with early treatment, is important. A 61-year-old Japanese man presented with an irreducible lump over his left groin, leading to the reduction of an incarcerated inguinal hernia by a doctor at another hospital. Later, he was admitted to our hospital with vomiting and abdominal pain. Computed tomography showed a ball-like lesion containing an incarcerated bowel loop over his left pelvis. The patient was diagnosed with an incarcerated small bowel obstruction due to a reduction en masse; a laparoscopic transabdominal preperitoneal (TAPP) hernioplasty was performed. TAPP hernioplasty is a safe method for treating reductions en masse that allows confirmation of bowel viability.

Beware of spontaneous reduction "en masse" of inguinal hernia

Reduction 'en masse' of inguinal hernia is a rare entity defined as manual reduction of an external hernia sac back through the abdominal wall but where its content still remains incarcerated or strangulated into a displaced position, most often in the pre-peritoneal space. Small bowel obstruction habitually follows requiring urgent repair, preferentially via a trans-abdominal approach. Pre-operative clinical diagnosis is difficult and abdominal CT-scan imaging is the investigation of choice.

Reduction en masse of inguinal hernia: MDCT findings of two cases

Reduction en masse of inguinal hernia is an extremely rare complication arising from manual reduction of a hernia. The hernial content remaining in the hernia sac returns above the inguinal canal but remains in the abdominal wall. Accurate preoperative diagnosis of reduction en masse of inguinal hernia is challenging because the hernia appears to be reduced upon physical examination. We experienced two cases of reduction en masse. In both cases, multidetector row computed tomography revealed a closed loop obstruction near the inguinal fossa. In addition, we observed a continuous tract of the hernia sac to the inguinal canal and prominent peritoneal thickening suggestive of the hernia sac.

Reduction en-masse of inguinal hernia with strangulated obstruction

"Reduction en masse of inguinal hernia" means reduction/migration of a hernial sac into the properitoneal space. We report the CT findings in a case of reduction en masse with strangulated obstruction. CT scan demonstrated a hernial sac with fibrous constriction band at the neck, situated in the properitoneal space superior to the inguinal region, causing closed-loop obstruction. The hernial sac contained thickened bowel loop with wall enhancement and fluid suggestive of incarceration/strangulation. We propose to call this, 'The properitoneal hernial sac sign', defined as "Presence of a hernial sac in the properitoneal space (and not in the inguinal/femoral canal) containing an obstructed/incarcerated bowel loop and causing small bowel obstruction" to identify "reduction en masse of inguinal hernia".
