A spontaneous external biliary fistula is most commonly a cholecystocutaneous fistula secondary to acute cholecystitis. A fistula arising from an intrahepatic duct is extremely rare. An 87-year-old man presented with swelling of the epigastric region and right upper quadrant abdomen. He had a history of cholecystectomy and endoscopic sphincterotomy. After antibiotic treatment and surgical opening of both lesions, abdominal computed tomography demonstrated a soft tissue mass cephalad to the umbilicus. We excised the mass, and found it to be associated with a fistula through the linea alba...

Endometriosis is defined by the presence of ectopic endometrial tissue outside the uterine cavity. Although it is a leading cause of chronic pelvic pain and infertility, its clinical presentation can vary, resulting in diagnostic and therapeutic challenges. Extrapelvic endometriosis is particularly difficult to diagnose owing to its ability to mimic other conditions. Endometrial tissue in a surgical scar is uncommon and often misdiagnosed as a granuloma, abscess, or malignancy. Cyclical hemorrhagic ascites due to peritoneal endometriosis is exceptionally rare...

PURPOSE: Adductor longus injuries are complex. The conflict between views in the recent literature and various nineteenth-century anatomy books regarding symphyseal and perisymphyseal anatomy can lead to difficulties in MRI interpretation and treatment decisions. The aim of the study is to systematically investigate the pyramidalis muscle and its anatomical connections with adductor longus and rectus abdominis, to elucidate injury patterns occurring with adductor avulsions. METHODS: A layered dissection of the soft tissues of the anterior symphyseal area was performed on seven fresh-frozen male cadavers...

Sante Capitano
BACKGROUND: In open surgery, extraperitoneal sublay mesh implantation is generally preferred to intraperitoneal placement, following the same principles as in "giant prosthetic reinforcement of the visceral sac" described for inguinal hernia repair [1, 2]. Miserez and Penninckx in 2002 described an endoscopic totally preperitoneal ventral hernia repair in a small cohort of 15 cases [3]. Unfortunately, this technique has not spread, probably because of the technical difficulties that require, but not for effectiveness...

Corey R Deeken, Spencer P Lake
Abdominal wall hernias are one of the most common and long-standing surgical applications for biomaterials engineering. Yet, despite over 50 years of standard use of hernia repair materials, revision surgery is still required in nearly one third of patients due to hernia recurrence. To date, hernia mesh designs have focused on maximizing tensile strength to prevent structural failure of the implant. However, most recurrences occur at the biomaterial-tissue interface. There is a fundamental gap in understanding the degree to which a mechanical mismatch between hernia repair materials and host tissue contributes to failure at this interface...

BACKGROUND: Diastasis of the rectus abdominis muscles (DRAM) is characterised by thinning and widening of the linea alba, combined with laxity of the ventral abdominal musculature. This causes the midline to "bulge" when intra-abdominal pressure is increased. Plastic surgery treatment for DRAM has been thoroughly evaluated, though general surgical treatments and the efficacy of physiotherapy remain elusive. The aim of this systematic literature review is to evaluate both general surgical and physiotherapeutic treatment options for restoring DRAM in terms of postoperative complications, patient satisfaction, and recurrence rates...

BACKGROUND: Patients with symptomatic umbilical, trocar, and/or epigastric hernias and concomitant rectus abdominis diastasis represent a growing clinical problem. The optimal management of this complex hernia situation is the subject of debate in the literature. This paper reports the early results of an innovative surgical technique aimed at managing this hernia situation. METHODS: Endoscopic-assisted linea alba reconstruction (ELAR) with mesh augmentation is a surgical technique long known in the literature for its good outcome for incisional hernia repair (myofascial release, overlapping herniorrhaphy, Gibson's operation, shoelace repair, anterior rectus sheath repair, dynamic patch plasty) via a small access route...

INTRODUCTION: Pyramidalis is classified as a vestigial muscle which is frequently present. It is muscle of the anterior abdominal wall. It is thought to tense the linea alba. It has been used as a surgical landmark, source of muscle stem cells and in various surgical procedures. AIM: The aim of this study was to describe the morphometry and morphology of pyramidalis muscle in an adult Indian population and its correlation with the clinical significance. MATERIALS AND METHODS: A cadaveric study on 25 formalin fixed cadavers (males-17, females-8) was conducted in context with prevalence, morphology and morphometry of pyramidalis muscle...

Sheldon M Lincenberg
Background: The retro-rectus placement of a prosthesis for reinforcement of a hernia repair is a powerful surgical maneuver and results in reduced hernia recurrence rates in the absence of ventral hernia. Fascial reinforcement theoretically should improve columnar support to the spine and enhance athletic activity. The purpose of this study was to demonstrate the long-term efficacy of the restoration of the cylindrical lumbar abdominal myofascial complex as an adjunct to cosmetic abdominoplasty...

There is a substantial prevalence of post-operative incisional hernia for both laparoscopic and laparotomy procedures, but there have been few attempts at quantifying abdominal wound closure methodology in the literature. One method to ascertain a more robust method of wound closure is the identification of the influence of suture placement parameters on suture pullout force. Current surgical practice involves a recommended bite depth and bite separation of 10mm, but the evidence base for this is not clear...

Surgical closure of giant abdominal wall hernia defects remains challenging. We report our initial experience with administration of botulinum toxin type A (BTA) for this approach in a 51-year-old female with a giant primary umbilical hernia and abdominal loss of domain. Four weeks prior to surgery, BTA was injected into the transverse abdominal and oblique muscles. During surgery the linea alba was reconstructed without lateral release procedures. At one-month follow-up, muscle relaxation had diminished and no surgical site occurrences were experienced...

Background: complex ventral hernia repair is a frequent and challenging topic. Reconstructive techniques are numerous but most of them are unable to achieve the goals of hernioplasty. Posterior component separation with transverses abdominis muscle release (TAR) is a novel approach that offers a solution for complex ventral hernias. METHOD: The posterior rectus sheath is incised and the retrorectus plane is developed. In a modification of the Rives-Stoppa technique, the transversus abdominis is released medial to the linea semilunaris to expose a broad plane that extends from the central tendon of the diaphragm superiorly, to the space of Retzius inferiorly, and laterally to the retro-peritoneum...

Background. Malignant neoplasms arising in Meckel's diverticulum, a vitelline duct remnant, are rare yet well-documented. Case Presentation. A 53-year-old previously healthy female presented with an enlarging midline abdominal wall mass. A computed tomography scan revealed a mass involving the linea alba, bilateral rectus abdominis, and subcutaneous fat. Extensive clinical workup failed to demonstrate other lesions, except local and paratracheal/hilar lymphadenopathy. Histopathologic examination of the resected tumor demonstrated a spectrum of serous neoplasia including serous cystadenoma, papillary serous carcinoma with numerous Psammoma bodies, and a poorly differentiated component...

Purpose: To investigate the interrater reliability of inter-rectus distance (IRD) measured from ultrasound images acquired at rest and during a head-lift task in parous women and to establish the standard error of measurement (SEM) and minimal detectable change (MDC) between two raters. Methods: Two physiotherapists independently acquired ultrasound images of the anterior abdominal wall from 17 parous women and measured IRD at four locations along the linea alba: at the superior border of the umbilicus, at 3 cm and 5 cm above the superior border of the umbilicus, and at 3 cm below the inferior border of the umbilicus...

The aim of this study is to characterize the passive mechanical behaviour of abdominal wall in vivo in an animal model using only external cameras and numerical analysis. The main objective lies in defining a methodology that provides in vivo information of a specific patient without altering mechanical properties. It is demonstrated in the mechanical study of abdomen for hernia purposes. Mechanical tests consisted on pneumoperitoneum tests performed on New Zealand rabbits, where inner pressure was varied from 0mmHg to 12mmHg...

STUDY DESIGN: An experimental model study and a short review of literature. OBJECTIVE: The purpose of this study was to explore a new hypothesis suggesting that the curvatures seen in adolescent idiopathic scoliosis (AIS) originate from restrained differential growth between the vertebral column and the surrounding musculo-ligamentary structures. SUMMARY OF BACKGROUND DATA: Despite decades of research, there is no generally accepted theory on the physical origin of the severe spinal deformations seen in AIS...

BACKGROUND: Laparoscopy is widely practiced and offers realistic benefits over conventional surgery. Port closure is important after a laparoscopic procedure to prevent port site incisional hernia. Larger port size and increasing numbers of ports needed to perform more complex laparoscopic procedures are likely to increase the incidence of port site hernias (PSHs). PSHs tend to develop more frequently at umbilical and midline port sites due to the thinness of the umbilical skin and weaknesses in the linea alba...
