The carolinas crossover, a preperitoneal crossover for enhanced-view totally extraperitoneal (eTEP) ventral hernia repair (VHR): a novel technique.

To present a novel technique of preperitoneal cross-over for eTEP VHR. Patients who underwent robotic eTEP with mesh utilizing a preperitoneal cross over technique were identified using a single-institution hernia database. This novel technique involves minimally invasive access to the retro-rectus space on one side with midline cross over into the preperitoneal space on the contralateral side. Baseline demographics of the patients were obtained, and intra-operative and post-operative outcomes were reported. Nine VHR patients underwent robotic eTEP with mesh using a preperitoneal crossover technique. Five patients were male, mean age was 53 ± 18.4 years, and mean BMI was 32.5 ± 4.2kg/m2. Two patients were diabetic and 2 were previous smokers. Two of the hernias were recurrent. The average hernia defect was 96.9 ± 45.5 cm2 and the average mesh size was 593.3 ± 168.2 cm2. Four patients underwent a unilateral TAR, while five patients did not require any component separation. All cases were CDC Class 1 wounds. All patients met discharge criteria on post-operative day 1. There was one post-operative wound occurrence which was a seroma. There were no infectious complications and no hernia recurrences. The average follow up was 1.4 ± 1.2 months. Preperitoneal cross-over during eTEP ventral hernia technique is a safe technique that allows placement of a large extra-peritoneal mesh. Early patient outcomes are favorable. Larger sample size and follow-up are needed to truly assess postoperative outcomes.

A prospective study comparing intra-operative and postoperative complications in totally extra peritoneal repair vs extended totally extra peritoneal for inguinal hernia

Introduction: Inguinal hernia repair is one of the most common surgical procedures worldwide. Total extra peritoneal repair (TEP) and Extended-TEP (eTEP) are widely used minimally invasive methods. TEP involves creating a space in the preperitoneal plane without entering the abdominal cavity, whereas eTEP extends this approach, allowing for a broader operative field.This study compares the intra-operative and postoperative complications of TEP and eTEP, contributing to the optimisation of inguinal hernia management. Methods: It is a prospective study. A total of 60 patients who underwent TEP and e-TEP for inguinal hernia, who fulfilled the inclusion criteria. Patients were randomised by simple random sampling technique and were divided into two groups of 30 each (group A-TEP and group B-eTEP). Data of both groups were compared and analysed for statistical significance using Chi square test and Student ‘t’ test. Result: The comparative analysis between TEP and eTEP procedures shows no significant differences in demographic parameters. However, eTEP demonstrates significantly shorter operative time and hospital stay, quicker return to work. Both procedures have similar rates of low intra-operative and postoperative complications, indicating comparable safety profiles. Conclusion: Our study suggest that both techniques are associated with low complication rates and good patient outcomes, with eTEP showing potential advantages in terms of pain, recovery and wider access. These findings help to take better surgical decision, to make and helped optimize patient care in inguinal hernia management.

EP612 - Laparoscopic repair of sciatic hernia: A demonstrative case on minimally invasive technique

Abstract Background Sciatic hernias are rare pelvic hernias that pose significant diagnostic and therapeutic challenges. A minimally invasive approach to repairing these defects offers the potential for reduced morbidity and quicker recovery. This report aims to highlight the feasibility, safety and provide an illustrative demonstration of the laparoscopic repair of a sciatic hernia. Methods A 72-year-old asymptomatic female diagnosed with a sciatic hernia underwent elective laparoscopic hernia repair as a day case. The preoperative evaluation, surgical technique and operative outcomes are detailed. Results A right-sided sciatic hernia containing a loop of the small bowel was diagnosed on cross-sectional imaging. Laparoscopically, a pre-peritoneal space in the right ovarian fossa was established, the hernia defect was delineated, and repair was performed using a polypropylene mesh prosthesis. No intraoperative or immediate postoperative adverse outcomes were reported. The patient was discharged on the same day, experiencing minimal discomfort, with a plan for outpatient follow-up. The literature on sciatic hernia repair is limited, and multiple operative techniques have been described. This report includes a step-by-step pictorial description of the laparoscopic sciatic hernia repair. Conclusion Laparoscopic repair of sciatic hernias can be performed safely and effectively, offering advantages such as reduced pain and faster recovery. This case underscores the importance of considering laparoscopic approaches for managing complex and rare hernias in the elderly population, emphasising tailored surgical planning and skilled execution.

WP1.11 - Total Extra Peritoneal (TEP) Inguinal hernia repair is safe and feasible for recurrent inguinal hernia post Total Extra Peritoneal repair "TEP on TEP is possible”

Abstract This abstract share our experience in surgical management of recurrent inguinal hernia post total extra peritoneal (TEP) repair by utilizing the same approach TEP. Methods Two patients with recurrent inguinal hernia post TEP were consulted for laparoscopic VS open approach, and both opted for the laparoscopic approach, understanding the higher risk of conversion. Result The first case of 62y male with recurrent left inguinal hernia after bilateral TEP. The second case of 69y male with recurrent left inguinal hernia post lap TEP repair. Standard three lower midline ports technique, no balloon spacer was used. The first and most important step was developing the plane above the previous mesh. 20 ml of 1 % xylocaine and 1/200000 was instilled in the extra peritoneal space to minimize oozing. Separating the previous mesh from the inferior epigastric artery and posterior wall of rectus muscle, down into bony lard marks and cord structures was performed using suction and sharp dissection with minimal diathermy. All landmarks were exposed in the three zones, before utilizing anatomical mesh. Both patients stayed overnight and operation time was 84 and 90 minute respectively. Three months follow up showed no recurrence or significant pain. Conclusion To our knowledge, this is first study describe the use of TEP on TEP. It suggests that TEP should not be excluded in patients with previous posterior mesh repair, emphasizing the importance of proper consultation. The abstract calls for further cases and studies to assess the efficacy and safety of this approach.

Elective complex ventral hernia repair in contaminated fields: A propensity score–matched analysis of long-term quality of life and outcomes between different prostheses

BackgroundRandomized studies have endorsed nonabsorbable prosthetics for contaminated ventral hernia surgery, yet the broader applicability and impact on patient-reported outcomes are still questioned. Here, we evaluated the long-term outcomes of elective contaminated ventral hernia repairs (based on Centers of Disease Control and Prevention [CDC] wound classification) using real-world data from a multicenter US cohort, focusing on quality of life and postoperative pain. MethodsThe Abdominal Core Health Quality Collaborative database was queried for patients undergoing elective contaminated (CDC class II–IV) ventral hernia repair (2013–2023). After propensity matching, we compared long-term differences in patient-reported quality of life and pain scores (by HerQLes and PROMIS questionnaires) among those who underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh. ResultsA total of 1,073 patients were included, of whom 920 (86%), 56 (5%), and 97 (9%) underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh, respectively. Among them, the median age was 62 years (interquartile range [IQR] 53–70), and 523 (49%) were male. The median length and width of the defect were 20 cm (IQR 12–25) and 13 cm (IQR 8–16), respectively. A transversus abdominis release was performed in 716 patients (67% of all cases). In most cases, the mesh was positioned in the retro-rectus (85%) and/or the preperitoneal space (45%). Before and after propensity matching (n = 185), the change from baseline in HerQLes and PROMIS scores at 6 months and at 1, 3, 5, and 6 years was comparable between different types of mesh. Lastly, there were no differences in readmission, surgical site infection, or surgical site occurrence at 30 days. Recurrence at 1 year was also comparable among groups. ConclusionIn the long term, there were no differences in quality of life or pain scores with nonabsorbable, absorbable synthetic, or biologic mesh for elective ventral hernia repair in contaminated fields.

RESULTS OF ENDOVIDEOSURGERY FOR INGUINAL HERNIA

Analysis of the results of treatment of inguinal hernias using endovideosurgical hernioplasty: TAPP, TEP and e-TEP in 216 patients was carried out. Total extraperitoneal hernioplasty (TER) is preferable for patients who have undergone operations on the abdominal cavity and pelvic organs due to the adhesion process. TARR is recommended when it is necessary to perform simultaneous operations and in case of bilateral localization of hernias. It made it possible to reduce the number of hematomas (in the TARR groups from 8.6% to 3.7%, in the TER-e-TER groups from 7.6% to 5.7%) and seromas (in the TARR groups from 8.6% to 7.4%, in the TER-e-TER groups from 13.5% to 5.7%) with dissection in the preperitoneal space.

Evaluation of Open Rives-Stoppa and Lichtenstein Repair Methods for Bilateral Inguinal Hernias: A Single-Centre Comparative Analysis.

Aim The purpose of the study is to compare the two common open surgical methods for bilateral inguinal hernias: bilateral Lichtenstein repair and Rives-Stoppa repair. It evaluates their benefits, drawbacks, and outcomes to improve the management of bilateral inguinal hernias and enhance patient care and results. Background Abdominal wall hernias are prevalent in the surgical field, and they occur when intra-abdominal organs protrude through weakened or torn regions in the abdominal wall. The Lichtenstein repair, also known as the tension-free mesh repair, is one of the most widely used techniques that involves placing a synthetic mesh over the hernia defect to reinforce the abdominal wall. The Rives-Stoppa technique takes the posterior approach, which involves placing a large mesh in the preperitoneal space, which provides broad coverage of the potential hernia sites. Method This retrospective study included 86 male patients from the Department of General Surgery at Indus Health Network, Karachi, Pakistan. Data were collected up to three months post-operation for all open bilateral inguinal hernia repairs performed between January 2017 and April 2021. The patients were divided into two groups: group A underwent Lichtenstein repair, while group B underwent Rives-Stoppa repair. The procedures were performed by different surgeons and surgical trainees under direct supervision. Results Regarding post-operative complications (scrotal swelling, epididymo-orchitis, seroma formation, ipsilateral testicular swelling, surgical site infection, erectile dysfunction, wound dehiscence, fever, hydrocele, sensory abnormality, hernia recurrence in 3 months, post-operative pain in 14 days), there was no significant difference observed between the two groups. There were two recurrences within three months after Lichtenstein repair and one recurrence after Stoppa repair, but no statistical difference was demonstrated. Conclusion Statistically, both the Lichtenstein repair and the Rives-Stoppa repair demonstrated similar outcomes. However, the Rives-Stoppa repair offers distinct advantages for bilateral inguinal hernia repair, making it a preferable option in many cases as this approach utilises a single midline incision, simultaneously facilitating access to both hernial sites. This method ensures complete coverage of the myopectineal orifices bilaterally, addressing all potential hernia sites in the lower abdomen. These features collectively contribute to the technique's efficacy in managing bilateral hernias.

The Peritoneum: Anatomy, Pathologic Findings, and Patterns of Disease Spread.

Disease spread in the abdomen and pelvis generally occurs in a predictable pattern in relation to anatomic landmarks and fascial planes. Anatomically, the abdominopelvic cavity is subdivided into several smaller spaces or compartments by key ligaments and fascial planes. The abdominal cavity has been traditionally divided into peritoneal, retroperitoneal, and pelvic extraperitoneal spaces. Recently, more clinically relevant classifications have evolved. Many pathologic conditions affect the abdominal cavity, including traumatic, inflammatory, infectious, and neoplastic processes. These abnormalities can extend beyond their sites of origin through various pathways. Identifying the origin of a disease process is the first step in formulating a differential diagnosis and ultimately reaching a final diagnosis. Pathologic conditions differ in terms of pathways of disease spread. For example, simple fluid tracks along fascial planes, respecting anatomic boundaries, while fluid from acute necrotizing pancreatitis can destroy fascial planes, resulting in transfascial spread without regard for anatomic landmarks. Furthermore, neoplastic processes can spread through multiple pathways, with a propensity for spread to noncontiguous sites. When the origin of a disease process is not readily apparent, recognizing the spread pattern can allow the radiologist to work backward and ultimately arrive at the site or source of pathogenesis. As such, a cohesive understanding of the peritoneal anatomy, the typical organ or site of origin for a disease process, and the corresponding pattern of disease spread is critical not only for initial diagnosis but also for establishing a road map for staging, anticipating further disease spread, guiding search patterns and report checklists, determining prognosis, and tailoring appropriate follow-up imaging studies. ©RSNA, 2024 Supplemental material is available for this article.

Robotic assisted extended view totally extraperitoneal repair for inguinal hernia

Robotic assisted transabdominal pre-peritoneal inguinal hernia repair is an effective and safe approach. This report describes a new technique of robotic extended view totally extraperitoneal repair. A supraumbilical retro rectus approach, creation of pre-peritoneal space, separation of hernia sac from cord structures, placement of mesh and fixing with vicryl suture was employed in a 58-year gentleman with right inguinal hernia. The surgery was performed with the use of a DaVinci robotic system. No intraoperative problems were encountered. The patient was discharged within 24 hours of surgical intervention. The work has been reported in line with the SCARE criteria. The patient had no groin pain, inguinal or scrotal swelling at 30 day follow up. He was pleased with the cosmetic result and has gone back to work. Robotic e-TEP is a viable option in inguinal hernia repair.

A head with two tales: demystifying early spread of disease from the pancreatic head.

The pancreas is a centrally located extraperitoneal organ within the anterior pararenal space. It is extensively connected to the extraperitoneal spaces by location and a network of mesenteries and ligaments. This provides interconnected avenues for vessels, lymphatics, and nerves to course through-as well as avenues for the spread of disease. The head of the pancreas results from the fusion of its ventral analog (anterior head) with its dorsal analog (posterior head). This differentiation provides two distinct pathways of spread of disease from the head of the pancreas. This communication will discuss the embryology, anatomy, and pathways of disease spread from the anterior and posterior pancreatic head. While any disease process can use these pathways, proven cases of adenocarcinoma of the pancreas are used for illustrations.

Trans rectus sheath extra-peritoneal procedure (TREPP) for inguinal hernia repair under local anesthesia with sedation in the outpatient clinic: a feasibility study.

The Trans Rectus Sheath Extra-Peritoneal Procedure (TREPP) is an open procedure in which the mesh is placed in the preperitoneal space and is therefore associated with less chronic post-operative inguinal pain. TREPP is primarily performed under general or spinal anesthesia, however, it is also possible to perform under sedation and local anesthesia with potentially advantages. This retrospective feasibility pilot study investigates the safety and efficiency of TREPP under local anesthesia in the outpatient clinic in comparison with Lichtenstein. Between 2019 and 2022, all patients who underwent an elective inguinal hernia repair under local anesthesia in the outpatient clinic operation theatre were assessed. 34 patients in the TREPP group and 213 patients in the Lichtenstein group were included. Outcomes were complications, operating time, theatre time, and early inguinal hernia recurrence within 8 weeks and 6 months post-operatively. No significant differences in complications such as wound infection, hematoma, seroma, urine retention and early recurrence between TREPP and Lichtenstein were found. Post-operative pain at 8 weeks was not significantly higher after Lichtenstein (8.8% vs. 18.8%, P = 0.22). Operating time (21.0 (IQR: 16.0-27.3) minutes vs. 39.0 (IQR: 31.5-45.0) minutes, P < 0.001) and theatre time (37.5 (IQR: 30.8-42.5) minutes vs. 54.0 (IQR: 46.0-62.0) minutes, P < 0.001) was significantly shorter for TREPP. This pilot study showed that TREPP appears to be feasible to perform safely under local anesthesia with comparable complication rates and substantially shorter operation time than Lichtenstein. These results justify further research with a larger study population and a longer period of follow up in order to provide firm conclusions.

ETEP AND TRANSVERSUS ABDOMINIS RELEASE IN A M5W3 INCISIONAL HERNIA

Abstract A 59-year-old female who underwent hysterectomy and exploratory laparotomy secondary to seromucinous ovarian carcinoma presents with discomfort in a partially reducible M5W3 incisional hernia. The patient is operated using a full endoscopic minimally invasive extraperitoneal approach (e-TEP + TAR). A 2 cm incision on the right subcostal region is made, exposing and opening the anterior rectal sheath (ARS), medializing the right rectus muscle. A dissection balloon is introduced to release the retromuscular space on the right side. A 10 mm trocar is placed in the right flank and a 5 mm trocar in the right iliac fossa. First, we access the medial posterior rectus sheath (PRS) of the right side, which is then incised, and the preperitoneal dissection is performed doing the crossover above the umbilicus. Once the hernia is completely reduced we connect both the retrorectus space with the preperitoneal spaces on both sides of the hernia. A modified posterior components separation (TAR) is performed on the left side, sectioning the aponeurosis of the transverse muscle (TM) and accessing the preperitoneal space laterally without sectioning the TM. The posterior and anterior defects are then closed separately using a barbed suture. A wide pore mesh, covering both retrorectus and preperitoneal spaces is placed and fixated using glue. An aspiration drainage was placed and removed 24 h after surgery. The patient was discharged the day after and no complications, where reported. In the CT scan 6 months after surgery the correction of the defects where confirmed.

CYSTIC INGUINAL LYNFHANGIOMA IN ADULT FEMALE

Abstract Background To present a clinical case of cystic inguinal lymphangioma in an adult female, an atypical site and age of presentation. Method A 42-year-old woman was referred for consultation due to persistent pain and swelling in the right inguinal region, with initial suspicion of inguinal hernia. A mobile, irreducible mass without protrusion during the Valsalva maneuver was identified. Faced with diagnostic uncertainty, inguinal ultrasound and magnetic resonance imaging were requested, revealing a cystic lesion indicative of cystic inguinal lymphangioma. Results Elective surgery was decided. A right inguinal incision revealed a cystic tumor extending along the inguinal canal from the labium majus to the preperitoneal space. Complete excision was performed, requiring section of the round ligament. Subsequently, closure of the deep inguinal ring was conducted, with the conjoint tendon approximated to the inguinal ligament using a continuous suture of slowly absorbable monofilament. Hernioplasty with self-adhesive polypropylene mesh was employed to repair the inguinal defect. The procedure was carried out in the ambulatory major surgery program. At the one-month post-surgery follow-up, the patient exhibited satisfactory recovery with no signs of clinical recurrence. Histopathological examination of the surgical specimen confirmed the diagnosis of cystic inguinal lymphangioma, with no additional pathological findings. Conclusion Cystic lymphangioma is a benign and uncommon malformation of the lymphatic system. It should be considered in cases of inguinal masses with progressive growth whose examination is not consistent with an inguinal hernia. Ultrasound is the imaging test of choice, with definitive diagnosis confirmed by histopathology. Surgery with complete resection is recommended due to the risk of recurrence.

Factors Associated With Infection in Patients With Combined Pelvic Ring and Bladder Injuries.

To identify the infection rate in patients with combined pelvic ring and bladder injuries. Secondary aims included identifying treatment and injury factors associated with infection. Retrospective review. Single Level I Tertiary Academic Center. All patients over a 12-year period with combined pelvic ring and bladder injuries were evaluated. Exclusion criteria were nonoperative management of the pelvic ring, isolated posterior fixation, and follow-up <90 days. Primary outcome measured was deep infection of the anterior pelvis requiring surgical irrigation and debridement. In total, 106 patients with anterior stabilization of the pelvis in the setting of a bladder injury were included. Seven patients (6.6%) developed a deep infection and required surgical debridement within 90 days. Patients undergoing open reduction and internal fixation with plating of the anterior pelvis and acute concomitant bladder repair had an infection rate of 2.2% (1/43). Patients undergoing closed reduction and anterior fixation with either external fixation or percutaneous rami screw after bladder repair had an infection rate of 17.6% (3/17). There was a higher infection rate among patients with combined intraperitoneal (IP) and extraperitoneal (EP) bladder injuries (23%) when compared with those with isolated EP (3.8%) or IP (9.1%) bladder injuries (P = 0.029). Acute open reduction and internal fixation of the anterior pelvis in patients with combined pelvic ring and bladder injuries has a low infection rate. Patients with combined IP and EP bladder injuries are at increased risk of infection compared with those with isolated IP and EP injuries. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Telescopic dissection versus balloon dissection during laparoscopic totally extraperitoneal inguinal hernia repair: A prospective randomised control trial.

Totally extraperitoneal (TEP) repair involves creating a preperitoneal space. The preperitoneal space can be created by balloon or telescopic dissection (TD). Nevertheless, these techniques may have some complications. However, there are very few studies that compare these two techniques. This study aims to assess the impact and comprehensively compare the TD and balloon dissection (BD) methods in patients undergoing laparoscopic TEP inguinal hernia repair. This was a single-centre, double-blinded, prospective, randomised, controlled trial comparing BD and TD for the creation of the preperitoneal space. The primary end point was to compare the post-operative pain score, intraoperative complications and surgical site occurrence between the two groups. The secondary end point was to assess the impact of the dissection technique on operative time for the creation of extraperitoneal space during laparoscopic TEP inguinal hernia repair. A total of 46 patients were included in the study (23 in each group). Baseline parameters were comparable between the groups. The total operative time between the groups (120 min vs. 160 min; P < 0.005) was statistically significant. The incidence of the peritoneal breach was statistically less in the BD group (43% vs. 13%; P < 0.005). Other short-term and long-term complications were less in the BD group but not statistically significant. BD in TEP inguinal hernia repair reduces the operative time and peritoneal breach. When compared to TD in terms of operative time, routine use of BD can be proposed. It will be beneficial in the early part of the learning curve.

Laparoscopic modified e-tep repair of concomitant inguinal and ventral hernias.

Laparoscopic hernia repair in recent times has gained the most acceptance among both the surgical community and the patient groups, as it has proven benefits of lesser postoperative hospital stay and less pain scores. The incidence of both inguinal and ventral hernias has increased significantly in the present days. Various methods have been postulated by different surgical groups for repairing the same but no there is no standard consensus on managing concomitant inguinal and ventral hernias. The conventional e-TEP requires an extensive dissection with increased operative time. We present our experience in managing cases with both inguinal and primary M2/M3 and W1 ventral hernias with or without divarication of recti using a modified up to down approach for inguinal hernia followed by down to up approach for the ventral hernia, from a tertiary care center in South India. We managed 16 cases with simultaneous incidence of inguinal and primary M2/M3 and W1 ventral hernias with or without divarication of recti between January 2022 and November 2023. Institute ethical committee clearance and informed consent was obtained from all the 16 patients. They were all subjected to an extra peritoneal repair of both the hernias. All the demographic data, intraoperative data, postoperative complications and follow up were digitally stored. All patients were followed up for six months after surgery. Out of 16 patients, 15 were males and 1 was female. The mean age was 48years and the mean BMI of all the patients was 29.2kg/m2. The postoperative recovery was smooth in all patients and being discharged within 24h after surgery. The pain scores of all patients were significantly lower than patients who underwent intraperitoneal repair. e-TEP hernia repair is gaining popularity and has amused the hernia surgical community. Our method of e-TEP RS repair in cases with concomitant inguinal and primary M2/M3 W1 ventral hernias with or without divarication helps in addressing both the hernias in the extra-peritoneal space. Our technique reduces the area of dissection needed for mesh placement and preserves the integrity of abdominal musculature in the upper abdomen when compared with the conventional technique. It further allows extension of the e-TEP inguinal space into the Rectro rectus space without much alteration in the port arrangement allowing simultaneous repair of groin and umbilical hernias. Good knowledge of anatomy and laparoscopic skills are pertinent for safe and effective hernia repair by this technique.

Open repair of flank and lumbar hernias: 142 consecutive repairs at a high-volume hernia center

BackgroundFlank and lumbar hernias (FLH) are challenging to repair. This study aimed to establish a reproducible management strategy and analyze elective flank and lumbar repair (FLHR) outcomes from a single institution. MethodsA prospective analysis using a hernia-specific database was performed examining patients undergoing open FLHR between 2004 and 2021. Variables included patient demographics and operative characteristics. ResultsOf 142 patients, 106 presented with flank hernias, and 36 with lumbar hernias. Patients, primarily ASA Class 2 or 3, exhibited a mean age of 57.0 ​± ​13.4 years and BMI of 30.2 ​± ​5.7 ​kg/m2. Repairs predominantly utilized synthetic mesh in the preperitoneal space (95.1 ​%). After 29.9 ​± ​13.1 months follow-up, wound infections occurred in 8.3 ​%; hernia recurrence was 3.5 ​%. At 6 months postoperatively, 21.2 ​% of patients reported chronic pain with two-thirds of these individuals having preoperative pain. ConclusionsOpen preperitoneal FLHR provides a durable repair with low complication and hernia recurrence rates over 2.5 years of follow-up.

Intraperitoneal instillation versus port-site infiltration or subcostal transversus abdominis plane block for post-operative analgesia following laparoscopic cholecystectomy

Background Although pain after laparoscopic surgery is less compared with open cholecystectomy, pain management in the first 24 to 72 h in the postoperative period is tricky and most patients complain of pain with cough, breathing and mobilization during the initial hours. The aim of this study was to evaluate the most efficacious route of analgesia in patients following laparoscopic cholecystectomy by comparing port-site wound infiltration, intraperitoneal infiltration and subcostal transversus abdominis plane block in providing post-operative analgesia following laparoscopic cholecystectomy. Methods This was an observational study performed on patients who underwent elective laparoscopic cholecystectomy at a tertiary care hospital in Mangalore. Group A received bupivacaine instilled in gallbladder fossa after removal of gall bladder before closure. Group B received Bupivacaine as an infiltration into the skin incision site (fascia, muscle, preperitoneal space) at each of the four port sites based on the length of the skin incision before closure. Group C received bupivacaine as subcostal transversus abdominis plane block under ultrasound guidance immediately postclosure. Collected data was entered in Microsoft Excel 2007 and analyzed using SPSS version 22.0 to find frequency, Mean and SD. Significance was assessed using Kruskal–Wallis test, χ 2 test and ANOVA for repeated measures. Results Hemodynamic parameters, i.e. the heart rate and mean arterial pressure were comparable at the end of 2 h and 4 h. At 6 and 8 h postoperatively however, visual analog scale was significantly better in group C compared with groups A and B. Time until the first analgesic request in group C was 359.35±45.55 min which was significantly lesser than the other two groups. Only three patients from group B had shoulder tip pain which was not seen in the other two groups. Conclusion Infiltration of bupivacaine at port sites is helpful in providing effective analgesia for upto 2 h post operatively whereas intraperitoneal instillation is both effective at meeting analgesic requirements as well as preventing shoulder tip pain. However, the substantial finding of our study is in providing further evidence to existing data that Subcostal transversus abdominis plane block can produce effective analgesia for laparoscopic cholecystectomy, effectively reduces analgesic requirement, and ensures faster recovery.

A Clinical-Anatomical-Radiological Study of Extraperitoneal Spaces: A Case Series.

Complications can arise secondary to anorectal suppurative diseases, with infections spreading along the extraperitoneal space, such as the peri-vesical, prevesical, pre-sacral, and pararectal spaces, resulting in abscesses at remote sites, which can make diagnosis more challenging. Due to the absence of peritonitis symptoms, there is a delay in presentation among such patients. Comprehending the intricacies of these areas and the way infection can spread within them is crucial for promptly identifying and effectively draining the extraperitoneal abscess. We present a case series of six patients with a mean age of 45, all males. A total of three patients had undergone incision and drainage after being diagnosed with anorectal suppurative disease and remained symptomatic after the initial surgical intervention of incision and drainage. Two patients initially diagnosed with anterior abdominal abscesses patients, after being treated with incision and drainage, continued to have purulent discharge from the drainage site. Finally, the last patient continued to present with perianal pain after an open hemorrhoidectomy. CTscans of all six patients showed collections in the extraperitoneal spaces correlated with the observed complications. To deepen our understanding of pelvic extraperitoneal spaces, cadaver dissections were conducted and compared with CT images. Through cadaver dissections and CT imaging, the study provides insights into the anatomy and interconnections of pelvic extraperitoneal spaces, emphasizing the importance of early CT scans for diagnosis. Understanding these intricate anatomical structures is essential for accurate diagnosis and efficient and effective treatment. Timely diagnosis is vital to prevent prolonged illness and reduce the risk of complications and mortality. The importance of early CT scans in suspected patients is underscored, which is highly important to expedite appropriate actions.

Mechanical shunt failure in hydrocephalus: a common but remediable complication with technical nuances

BackgroundA ventriculoperitoneal (VP) shunt is a cerebral shunt that diverts excess cerebrospinal fluid (CSF).Obstruction in the normal outflow or decreased absorption of the fluid is the usual cause. Hydrocephalus is treated by cerebral shunts.In paediatric patients, untreated hydrocephalus can be lethal and leads to many adverse effects including increase irritabilities, chronic headaches, learning difficulties, visual disturbances, and, in more advanced cases, severe mental retardation. Malfunction of the shunt with excess CSF accumulated can increase the intracranial pressure resulting in cerebral oedema and ultimately herniation.ObjectiveTo study and evaluate the mechanical causes of shunt failure and their surgical remedies and reduce the preventable morbidity, cost and mortality associated with shunt failure.MethodsWe conducted a prospective observational study including 70 patients who developed pure mechanical shunt failure for the first time from 2017 to 2020 in the Department of Neurosurgery Sher-i-kashmir Institute of Medical Sciences. Patients with previous shunt surgeries which include VP shunting and shunt revision or failure and shunt infections were excluded. Identity of all the patients has been kept anonymus. Written informed consent was obtained from all patients or their guardians in case of minors. Shunt malfunction was in the form of catheter misplacement, kinking, displacement from the ventricle or peritoneal cavity, disconnection, migration,inadvertent suturing of the catheter, air in shunt bulb.ResultsWe found kinking at the proximal end in 25 (35%) patients as the most common cause of shunt failure. It was mostly as a result of inadequate and less spacious tunnelling made for the reservoir. Inadvertant suturing of shunt while closing abdomen in 7 (10%), shunt disconnection in 6 (8.5%), air in shunt bulb in 2 (2.8%), wrong placement at ventricular end in 10 (14.2%), shunt migration into the brain parenchyma in 5 (7.1%), shunt migration through the anal canal in 1(1.4%), pseudomeningocele around catheter valve in 3 (4.2%), placement of lower end into the preperitoneal space in 4 (5.7%) patients.ConclusionsShunt surgery is seemingly a straightforward operation for neurosurgeons. But considering the incidence of shunt failure and its associated morbidity and mortality, it should always be done with trepidation and extreme caution. Exclusive mechanical shunt malfunction is a major concern and leads to great deal of morbidity in the shunt operations. However, there are trivial remedies and technical nuances which needs to be followed during surgery to avoid these complications.
