We present a mini case series of four patients aged 72 to 86 years who presented to our tertiary referral center at the University Hospitals of North Midlands UK, between 2019 and 2022.The case series documents the challenges of managing pheochromocytoma in this population, emphasizing how close monitoring, regular follow ups and collaboration between different members of the multidisciplinary team helped to achieve the desirable outcomes in these cases. Case 1: Adrenal incidentaloma in 84-year-old female. Background of hypertension and diabetes mellitus. History of occasional palpitations. Investigations showed raised plasma and urinary metanephrines. MIBG scan confirmed pheochromocytoma and after adequate alpha and beta blockade underwent successful laparoscopic surgery. No intra or post operative complications and showed good recovery. Discharged on the 5th day post operative. Case 2: 82-year female under cardiology with non-ST elevation myocardial infarction. Background of hypertension, chronic kidney disease and gastroesophageal reflux disease. Initial presentation with shortness of breath, sweating and swelling lower limbs. Normal coronary arteries on angiography, so investigated for possible excess catecholamine production. Had significantly raised 24-hour urinary normetadrenaline. Paraaortic paraganglioma confirmed on MIBG SPECT scan. Initially opted for medical treatment however quality of life worsened over the next year and eventually underwent robot assisted excision. Procedure was uneventful with good post-operative recovery. Was able to go home 2 days after the procedure. Case 3: 72-year-old female referred with right adrenal incidentaloma. Background of hypertension, diabetes mellitus, hypothyroidism, asthma, arthritis and Ca breast treated 10 years ago. Results showed raised plasma metanephrines, subsequently, MIBG scan revealed a 3 cm right adrenal nodule with increased uptake. Full alpha and beta blockade achieved before she underwent surgical treatment with no complications. Discharged on the 3rd day post op. Case 4: An 80-year-old male was referred with left adrenal incidentaloma. History of diabetes, chronic kidney disease, ischemic heart disease and heart failure, recent myocardial infarction and atrial fibrillation. Biochemical and radiological investigations confirmed pheochromocytoma. He was started on alpha blockade that proved difficult to achieve due to underlying co-morbidities. The patient needed close monitoring by the endocrine team and was finally established on adequate alpha and beta blockade. Due to significant risks associated with the procedure, the patient decided not to proceed with the surgery and opted for medical management. Remains under active follow up. Presentation: 6/2/2024

Deep neuromuscular blocking and sugammadex reversing-drug is an efficient strategy permitting successful laparoscopic surgery under low insufflation pressure: Prospective multicenter study

ABSTRACT Objectives To compare using deep neuromuscular blockade during low abdominal insufflation pressure (DNMB/LAIP; n = 67) to conventional blockade and pressure (CNMB/CAIP; n = 68) for laparoscopic cholecystectomy and to evaluate the speed and efficacy of NMB recovery using sugammadex (SGX) as assessed by the Postoperative Quality Recovery Scale. Patients & Methods Rocuronium initiation and maintenance doses were 0.6 and 0.15 mg/Kg, respectively, and neostigmine or SGX was used as reverse agent for CNMB and DNMB, respectively. Abdominal insufflation was terminated at 15 and 8-mmHg, for CAIP and LAIP, respectively. The study outcome is the surgical feasibility under DNMB/LAIP, as judged by the frequency of shift-to-CAIP, surgical field visibility and operative time. Results The frequency of shift-to-CAIP was 2.9% due to surgeons’ inconvenience of LAIP. DNMB allowed significant control of intraoperative (IO) hemodynamic response to surgical manipulations. SGX allowed 3.2 times faster NMB-reversal with significantly higher percentages of patients returned to baseline physiologic statuses. The percentage of patients free of pain and nausea was significantly higher after DNMB/LAIP. At hospital discharge and day-7 PO, 86.6% and 98.5% of patients regained normalcy of their overall perspectives after DNMB/LAIP with a significant difference than after CNMB/CIAP. At 2-week PO, the frequency of shoulder-tip pain (STP) was significantly lower and surgeons’ satisfaction rate was significantly with DNMB/LAIP. Conclusion Laparoscopic cholecystectomy under DNMB/LAIP procedure is feasible and safe with lower incidence and severity of STP and high surgeons’ satisfaction. Sugammadex hastened the recovery of DNMB 3.2 times that of neostigmine-induced recovery of CNMB. Registration NO: RC.3.9.2023

Tubal Stump Ectopic Pregnancy with Acute Abdomen: A Rare Case Report

Ectopic pregnancy, characterized by the implantation of the gestational sac outside the uterine cavity, is a grave condition. The objective of this study is to report a case of recurrent ectopic pregnancy in the residual site of the same fallopian tube, which had undergone unilateral salpingectomy due to ectopic pregnancy five years prior. Despite its rarity in the literature, tubal stump ectopic pregnancy poses higher risks of maternal mortality and morbidity compared to other types of tubal ectopic pregnancies. It is important to note that a history of salpingectomy does not exclude the possibility of ipsilateral recurrent ectopic pregnancy. Furthermore, this is the first documented case of stump tubal ectopic pregnancy from Turkey.

The impact of pre-operative cholecystostomy on laparoscopic excision of choledochal cyst in paediatric patients.

This aim of this study was to identify the pre-operative risk factors for conversion during laparoscopic excision of choledochal cyst in paediatric patients. A retrospective single-centre study was carried out. All paediatric patients (< 18years) who had undergone laparoscopic excision of choledochal cyst between 2004 and 2021 were reviewed. The outcome was conversion to open surgery and pre-operative factors that affected the conversion rate were analyzed. Sixty-one patients were included. Conversion was required in 24 cases (39.3%). There was no difference in the conversion rate between the first (before 2012, n = 30) and second (after 2012, n = 31) half of the series (36.7% vs. 42.0%, p = 0.674). Majority was type 1 cyst (86.8%) and the median cyst size was 4.6cm (IQR: 2.2-6.4cm). Antenatal diagnosis was available in 18 patients (29.5%). The median age at operation was 23.0months (IQR: 8.0-72.0months). Pre-operatively, 19 patients (31.1%) suffered from cholangitis and 5 (8.2%) of them required cholecystostomy. Comparing patients with successful laparoscopic surgery (L) and converted cases (C), there were no differences in the age at operation (p = 0.74), cyst size (p = 0.35), availability of antenatal diagnosis (p = 0.23) and cholangitic episodes (p = 0.40). However, a higher percentage of patients required cholecystostomy in the converted group (L vs. C = 2.7% vs. 16.7%, p = 0.05). Using logistic regression analysis, it was also a risk factor for conversion (OR = 3.5 [1.37-5.21], p = 0.05). Pre-operative cholecystostomy is a potential risk factor for conversion during laparoscopic excision of choledochal cyst in children.

Which surgical approach is more favorable for pheochromocytoma of different sizes (< 6 cm vs. ≥ 6 cm)? A single retrospective center experience

BackgroundTo compare the surgical effects of lateral transperitoneal approach (LTA) and posterior retroperitoneal approach (PRA) for pheochromocytoma of different sizes.MethodsData on patients with pheochromocytoma from 2014 to 2023 were collected from our hospital. According to different surgical approaches and tumor size, all patients were divided into four groups: tumor size < 6 cm for LTA and PRA and tumor size ≥ 6 cm for LTA and PRA. We compared these two surgical methods for pheochromocytoma of different sizes.ResultsA total of 118 patients with pheochromocytoma underwent successful laparoscopic surgery, including PRA group (n = 80) and LTA group (n = 38). In tumor size < 6 cm, the outcomes were no significant difference in LTA and PRA. In tumor size ≥ 6 cm, there was a significant difference in operation time (214.7 ± 18.9 vs. 154.3 ± 8.2, P = 0.007) and intraoperative blood loss (616.4 ± 181.3 vs. 201.4 ± 45.8, P = 0.037) between LTA and PRA.ConclusionLTA and PRA were performed safely with similar operative outcomes in patients with pheochromocytoma size < 6 cm. While both LTA and PRA were executed with a commendable safety profile and comparable operative results in patients afflicted by pheochromocytomas < 6 cm, the PRA technique distinctly showcased advantages when addressing large-scale pheochromocytomas (≥ 6 cm). Notably, this manifested in reduced operative time, diminished intraoperative blood loss, decreased hospitalization expenses, and a paucity of procedural complications.

Development and validation of a deep learning-based laparoscopic system for improving video quality.

A clear surgical field of view is a prerequisite for successful laparoscopic surgery. Surgical smoke, image blur, and lens fogging can affect the clarity of laparoscopic imaging. We aimed to develop a real-time assistance system (namely LVQIS) for removing these interfering factors during laparoscopic surgery, thereby improving laparoscopic video quality. LVQIS was developed with generative adversarial networks (GAN) and transfer learning, which included two classification models (ResNet-50), a motion blur removal model (MPRNet), and a smoke/fog removal model (GAN). 136 laparoscopic surgery videos were retrospectively collected in a tripartite dataset for training and validation. A synthetic dataset was simulated using the image enhancement library Albumentations and the 3D rendering software Blender. The objective evaluation results were through PSNR, SSIM and FID, and the subjective evaluation includes the operation pause time and the degree of anxiety of surgeons. The synthesized dataset contained 19,245 clear images, 19,245 motion blur images, and 19,245 smoke/fog images. The ResNet-50 CNN model identified whether a single laparoscopic image had motion blur and smoke/fog with an accuracy of over 0.99. The PSNR, SSIM and FID of the de-smoke model were 29.67, 0.9551 and 74.72, respectively, and the PSNR, SSIM and FID of the de-blurring model were 26.78, 0.9020 and 80.10, respectively, which were better than other advanced de-blurring and de-smoke/fog models. In a comparative study of 100 laparoscopic surgeries, the use of LVQIS significantly reduced the operation pause time (P < 0.001) and the anxiety of surgeons (P = 0.004). In this study, LVQIS is an efficient and robust system that can improve the quality of laparoscopic video, reduce surgical pause time and the anxiety of surgeons, and has the potential for real-time application in real clinical settings.

A case in which the ileocolic vein draining into the gastrocolic trunk of Henle could be diagnosed preoperatively: a rare anatomical case report

BackgroundNumerous variations in vascular anatomy have been reported in the right colon. The ileocolic vein (ICV) generally drains directly into the superior mesenteric vein (SMV), and is an important landmark for laparoscopic surgery in right colon cancer. We present here a patient with a vascular anomaly of the ICV that was diagnosed on preoperative imaging.Case presentationA 65-year-old woman was diagnosed with transverse colon cancer by colonoscopy. Preoperative computed tomography scan showed that the ICV drained into the gastrocolic trunk of Henle (GCT) rather than the SMV. Single-incision laparoscopic transverse colectomy with D3 lymph node dissection was performed, dividing the middle colic vein (MCV) and preserving the right gastroepiploic vein (RGEV), anterior superior pancreaticoduodenal vein (ASPDV), GCT and ICV. The intraoperatively identified venous anatomy was consistent with the preoperative evaluation, and the RGEV, ASPDV and ICV were found to form the GCT.ConclusionWe report a rare vascular anatomical anomaly that was diagnosed preoperatively, facilitating safe and successful single-incision laparoscopic surgery with D3 lymph node dissection.

Comparative Analysis of Peri-Operative Outcomes Following Total Laparoscopic Hysterectomy with Conventional Bipolar-Electrosurgery versus High-Pressure Pulsed LigaSure Use.

Objectives:Quick and effective hemostasis is essential for a successful laparoscopic surgery. Hence, it is of utmost importance for laparoscopic surgeons to understand the various available and emerging energy sources to tailor their use according to their properties and surgical requirement. The aim of this study was to compare LigaSure, an advanced bipolar versus conventional bipolar in total laparoscopic hysterectomy, with respect to operating time, mean blood loss, mean reduction in hemoglobin, intraoperative, and postoperative complications, and duration of prospective hospital stay.Materials and Methods:It was a randomized controlled study. One hundred and twenty patients scheduled for elective hysterectomy for any benign indication were randomly allocated to two groups namely, conventional bipolar group and LigaSure group. Patients with a history of ≥3 laparotomies, uterine size >20 weeks were excluded. Total laparoscopic hysterectomy with bilateral salpingectomy/salpingo oophorectomy was done in all the patients and endpoints were evaluated.Results:All the recruited participants (n = 120) achieved study endpoints. There was statistically significant difference in the meantime to dissect adnexal ligaments, primary and total operating time (for adnexal ligaments: Conventional bipolar-9.44 min vs. LigaSure-7.05 min; P = 0.000) (Primary: Conventional bipolar-97.03 min vs. LigaSure 74.39 min; P = 0.000) (Total: 142.5 min vs. 136.37 min P = 0.002). Mean blood loss (145 ml vs. 141.67 ml; P = 0.846), mean reduction in hemoglobin (0.802 versus 0.752; P = 0.484) and duration of postoperative stay (2.54 days vs. 2.32 days; P = 0.128) were comparable (P > 0.05). None of the participants suffered from any major complication during the surgery or in the postoperative recovery period.Conclusion:With an ability to effectively reduce operating time, LigaSure is a safe and efficient instrument for laparoscopic hysterectomy.

Laparoscopic approach for managing intussusception in children: Analysis of 65 cases.

BACKGROUNDIntussusception can be managed by pneumatic reduction, ultrasound-guided hydrostatic reduction, open or laparoscopic surgery, but laparoscopy in such cases remains controversial. AIMTo explore the clinical characteristics, effectiveness, and complications of surgical reduction for intussusception using laparoscopy in children. METHODSThis study was a retrospective case series of pediatric patients with intussusception who underwent surgical reduction by laparoscopy from May 2011 to April 2016 at Taizhou Hospital of Zhejiang Province. Clinical characteristics (operation time, intraoperative blood loss, conversion rate of laparotomy, reasons for conversion, postoperative hospital stay, and adverse events) were described.RESULTSThe 65 patients included 45 boys and 20 girls. The average age was 2.3 years (27.5 ± 24.5 mo). Of the 65 patients, 61 underwent surgical reduction by laparoscopy after a failed enema reduction of intussusception, and four underwent the procedure directly. All patients were treated successfully and 57 (87.7%) patients underwent successful laparoscopic surgery, two of which had a spontaneous reduction. Among the remaining cases, one was converted to open surgery via right upper quadrant incision, and seven required enlarged umbilical incisions. Intestinal resection was performed in 5 patients because of abnormal bowel lesions. There were no complications (intestinal perforations, wound infections, or intestinal adhesions) during the follow-up of 3 years to 8 years. Two patients experienced a recurrence of intussusception; one was resolved with pneumatic reduction, and the other underwent a second laparoscopic surgery. CONCLUSIONLaparoscopic approach for pediatric intussusception is feasible and safe. Bowel resection if required can be performed by extending umbilical incision without the conventional laparotomy.

A successful Laparoscopic surgery for multiple hydatid cysts (7 cysts) of liver : Case Report

Case report : To the best of our knowledge this could be the first report of a successfully performed laparoscopic surgery for female patient having had multiple liver hydatid cysts ( 7 in number) in both lobes of liver. Background: Laparoscopic hydatid surgery ( LHS) was almost gaining acceptance all over the world. But still there are contraindications to this approach of particular are those with multiple cysts ( >3 cysts)1.On reviewing the literature most of the reports of LHS were for patients with solitary hydatid cyst and exceptionally for a maximum of three cysts. Herein an initial effort to expand the application of LHS in managing multiple hydatid cysts of liver (>3) with all the advantages of laparoscopic approach; less pain, good cosmetic results, rapid recovery and less complications

Can MRI pelvimetry predict the technical difficulty of laparoscopic rectal cancer surgery?

Selection of an open or minimally invasive approach to total mesorectal excision (TME) is generally based on surgeon preference and an intuitive assessment of patient characteristics but there consensus on criteria to predict surgical difficulty. Pelvimetry has been used to predict the difficult surgical pelvis, typically using only bony landmarks. This study aimed to assess the relationship between pelvic soft tissue measurements on preoperative MRI and surgical difficulty. Preoperative MRIs for patients undergoing laparoscopic rectal resection in the Australasian Laparoscopic Cancer of the Rectum Trial (ALaCaRT) were retrospectively reviewed by two blinded surgeons and pelvimetric variables measured. Pelvimetric variables were analyzed for predictors of successful resection of the rectal cancer, defined by clear circumferential and distal resection margins and completeness of TME. There was no association between successful surgery and any measurement of distance, area, or ratio. However, the was a strong association between the primary outcome and the estimated total pelvic volume on adjusted logistic regression analysis (OR = 0.99, P = 0.01). For each cubic centimeter increase in the pelvic volume, there was a 1% decrease in the odds of successful laparoscopic rectal cancer surgery. Intuitive prediction of unsuccessful surgery was correct in 43% of cases, and correlation between surgeons was poor (ICC = 0.18). A surgeon's intuitive assessment of the difficult pelvis, based on visible MRI assessment, is not a reliable predictor of successful laparoscopic surgery. Further assessment of pelvic volume may provide an objective method of defining the difficult surgical pelvis.

Laparoscopic transperitoneal adrenalectomy in the large adrenal tumor from single center experience

BackgroundThe role of laparoscopic adrenalectomy (LA) in a large adrenal tumor is controversial due to the risk of malignancy and technical difficulty. In this study, we compared the perioperative outcomes and complications of LA on large (≥ 6 cm) and (< 6 cm) adrenal tumors.MethodsWe retrospectively reviewed all clinical data of patients who underwent unilateral transperitoneal LA in our institution between April 2000 and June 2019. Patients were classified by tumor size into 2 groups. Patients in group 1 had tumor size < 6 cm (n = 408) and patient in group 2 had tumor size ≥ 6 cm (n = 48). Demographic data, perioperative outcomes, complications, and pathologic reports were compared between groups.ResultsPatients in group 2 were significant older (p = 0.04), thinner (p = 0.001) and had lower incident of hypertension (p = 0.001), with a significantly higher median operative time (75 vs 120 min), estimated blood loss (20 vs 100 ml), transfusion rate (0 vs 20.8%), conversion rate (0.25 vs 14.6%) and length of postoperative stays ( 4 vs 5.5 days) than in group 2 (all p < 0.001). Group 2 patients also had significantly higher frequency of intraoperative complication (4.7 vs 31.3%; adjust Odds Ratio [OR] = 9.67 (95% CI 4.22–22.17), p-value < 0.001) and postoperative complication (5.4 vs 31.3%; adjust OR = 5.67 (95% CI 2.48–12.97), p-value < 0.001). Only eight (1.8%) major complications occurred in this study. The most common pathology in group 2 patient was pheochromocytoma and metastasis.ConclusionsLaparoscopic transperitoneal adrenalectomy in large adrenal tumor ≥ 6 cm is feasible but associated with significantly worse intraoperative complications, postoperative complications, and recovery. However, most of the complications were minor and could be managed conservatively. Careful patient selection with the expert surgeon in adrenal surgery is the key factor for successful laparoscopic surgery in a large adrenal tumor.Trial registration: This study was retrospectively registered in the Thai Clinical Trials Registry on 02/03/2020. The registration number was TCTR20200312004.

Comparative Study of Role of Laparoscopic Vs Conventional Management in Peritonitis

Background : A very commonly encountered case in the field of general surgery is peritonitis. In our study, we analyse 100 cases of acute peritonitis due to various causes, being managed conventionally and laparoscopicaly. Subjects and Methods: The observational, continuous, prospective, single centre study was carried out at Gujarat Adani Institute of Medical Science at GK General Hospital Bhuj. The study was conducted for a total duration of 27 months from October 2017- December 2019 (Patients were enrolled in the study and followed up till the day of admission to the day of the discharge). Total 100 patients are enrolled in the study but there were no intervention done. We compare the outcomes in terms of postoperative pain, removal of ryles tube, urinary catheter, drains, early ambulation and duration of hospital stay. Results: Maximum patients were diagnosed as having pre pyloric peptic (pyloric with antral perforation) perforation (45%) followed by jejunal perforation (17%). successful laparoscopic surgery without conversion was done in 92%. study total 4 cases of laparoscopic managed group needed to convert in open including 2 duodenal perforation cases, 1 sigmoid colon perforation case and 1 ascending colon perforation. Conclusion: Laparascopic intervention to be better of the two provided availability of skill and setup.

Economic analysis of sugammadex versus neostigmine for reversal of neuromuscular blockade for laparoscopic surgery in China

BackgroundNeuromuscular blockade and pneumoperitoneum (PP) are important factors to ensure successful laparoscopic surgery. However, residual neuromuscular blockade (rNMB) and PP are associated with many unfavorable complications. The aim of this study is to compare the cost-effectiveness of using sugammadex versus neostigmine in laparoscopic surgery in China.MethodsA decision tree model was developed with a time horizon based on laparoscopic surgery related hospitalization duration. 2000 patients using sugammadex or neostigmine were simulated within the model. The model outcomes included incidence of rNMB and PP related complications and their treatment costs. Data on clinical efficacy, safety and cost were collected from published literature and interviews of physicians.ResultsThe model projected that treatment with sugammadex instead of neostigmine would lead to 673 fewer total complications, including rNMB/PP related complications, hospitalization, and other AEs (621 events versus 1294 events, respectively). Use of sugammadex was associated with an incremental medication cost of ¥1,360,410. However, 93.6% of the increased medication cost can be off-set by the reduced costs attributable to treatment of rNMB related complications, PP related complications, hospitalization and other adverse events in sugammadex group. In aggregate, the sugammadex group incurred an incremental cost of ¥86,610 to prevent 673 complications, (¥128.56 per one rNMB/PP related complications prevention). One-way sensitivity analysis confirmed the robustness of the model.ConclusionsUse of sugammadex in replacement of neostigmine would result in significantly lower rNMB/PP related complications but at a substantially higher medication cost. Upon accounting for the costs associated with treatment of rNMB/PP related complications, 93.6% of medication cost is projected to be offset. In balance, sugammadex appears to offer good value for reversal of neuromuscular blockade for laparoscopic surgery in China.

Successful laparoscopic surgery combined with selective arterial embolization for bleeding due to jejunal angiodysplasia: a case report

BackgroundAngiodysplasia of the gastrointestinal tract is a rare vascular pathology that sometimes causes massive hemorrhage. Angiodysplasias are particularly difficult to find in the small intestine for anatomical reasons, often impeding their diagnosis and treatment. Lesion localization is a major challenge in cases of small bowel bleeding requiring surgical intervention.Case presentationThe present case was a 52-year-old woman who was urgently hospitalized with repeated tarry stools. Surgical intervention was chosen after conservative treatment failed to improve her condition. The source of bleeding was suspected to be a vascular lesion discovered in the small intestine during a past double-balloon endoscopy. Abdominal contrast computed tomography revealed a jejunal hemorrhage. We chose selective arterial embolization to stabilize her hemodynamics followed by surgical intervention as her treatment plan. Several embolic and contrast agents (cyanoacrylate, indigo carmine, and Lipiodol) were combined to help identify the location of the lesion during surgery. This multi-pronged approach allowed us to localize the lesion under laparoscopic guidance with high confidence and accuracy, and to excise a 6-cm segment of the small intestine. The lesion was histologically diagnosed as angiodysplasia. No re-bleeding has been observed since the operation.ConclusionWe report our experience with a case of jejunal angiodysplasia, which was localized with selective arterial embolization using an array of embolic and contrast agents, and then excised laparoscopically. Selective arterial embolization with indigo carmine dye to treat small bowel bleeding preoperatively not only makes the surgery safer by stabilizing the patient’s hemodynamics, but is also very useful for localizing the lesion intraoperatively.

Re-operation surgery following IPAA: is there a role for laparoscopy?

Restorative proctocolectomy with ileal J pouch anal anastomosis (IPAA) has become the standard of care for mucosal ulcerative colitis and Familial Adenomatous Polyposis. Some patients require re-operation, including pouch revision, advancement, or excision. Re-operative procedures are technically demanding and usually performed only by experienced colorectal surgeons in a small number of referral centers. There is a paucity of data regarding feasibility, safety, and outcomes of laparoscopic re-operative IPAA surgery. This study aimed to determine the safety and feasibility of laparoscopic approach for re-operative IPAA, trans-abdominal surgery. Retrospective analysis of IRB-approved prospective database for patients who underwent trans-abdominal re-operative IPAA from 2011 to 2018. Patient demographics and operative reports were reviewed to classify type of re-operationinto pouch excision, revision, or advancement and further classify as laparoscopic, laparoscopic converted to open, or open surgery. Main outcome measures were post-operative morbidity and mortality. Seventy-six patients met the inclusion criteria: 19 underwent attempted laparoscopic re-operative IPAA surgery, 12 of whom underwent successful laparoscopic surgery while 7 were converted to laparotomy, for an overall laparoscopic intent to treat 63% success rate. The remaining operations (n = 57) were performed through midline laparotomy. Length of stay (LOS) for patients who underwent laparoscopic surgery was significantlyshorter (5.5 vs 9.7days, p < 0.001) as were abdominal superficial surgical site infections (SSI) (0% vs 18%, p < 0.001) and deep SSI (0% vs 17%, p < 0.001). Laparotomy was performed by 6 colorectal surgeons at our institution while laparoscopy was successfully performed only by the senior author. There was no significant difference in overall complications, re-admission, re-operation, or mortality. Re-operative, trans-abdominal, laparoscopic IPAA is both feasible and safe and has clear benefits compared to laparotomy in terms of LOS and superficial and deep SSI. However, this approach needs to be undertaken only by very experienced, high-volume laparoscopic IPAA surgeons.

Unicentric Castleman’s Disease Presenting as Retroperitoneal Pelvic Lymph Node in Young Female—Laparoscopic Excision: A Case Report

Unicentric Castleman’s disease (UCD) is localized lymphoproliferative disease and has favourable prognosis. Surgery offers complete cure of unicentric Castleman disease. Radiotherapy offers either complete response or variable clinical response and cure in selected patients. The present case report is of a young unmarried obese girl presented with pain in right iliac fossa for 2 months. On pelvic ultrasound and MRI performed for diagnosis only single enlarged right external iliac lymph node was the positive finding. The CT scan guided biopsy was performed and the histopathological finding was lymphoid lesion-reactive lymphoid hyperplasia is favoured over Hodgkin’s lymphoma. Successful laparoscopic complete excisional surgery was performed for this single enlarged external iliac lymph node. The final histopathological report of the lymph node removed was unicentric Castleman’s disease, hyaline vascular type. This is the 16th such reported case of pelvic retroperitoneal UCD of hyaline vascular type treated by surgical excision, and 3rd case treated by Laparoscopic excisional surgery. By now at the time of reporting this case 4 months of follow up has been completed and patient does not have any symptom nor not show any sign of residual disease locally on transabdominal ultrasound examination and whole-body PET CT scan is also normal.
