Telementoring Experience for Complex Bariatric Operation-Laparoscopic Single-Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S).

In a groundbreaking surgical collaboration, a team of surgeons in Lithuania successfully performed the first single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) operation under the remote telemonitoring guidance of a highly experienced surgeon from Spain.The Lithuanian surgical team, comprising skilled bariatric surgeons, meticulously prepared for the SADI-S operation under the remote guidance of their Spanish proctor. Utilizing video conferencing and real-time communication, the mentor provided step-by-step instructions, shared insights, and addressed any concerns during the procedure. The mentor's extensive experience and guidance ensured a safe and successful surgical outcome.This innovative approach not only demonstrates the potential of telemedicine in the field of complex bariatric surgeries but also highlights the power of international cooperation in advancing surgical techniques and patient care by using modern methods of telemedicine and proctorship.

Vermiform Appendix within Post-Laparoscopic Incisional Hernia: A Unique Case Report and Literature Review.

Background: Appendicitis within incisional hernia is an extraordinarily rare postoperative complication with an incidence range from 0.08 to 1%. From the 14 cases that we found in the English literature, only three present appendixes vermiform in incisional hernia followed by laparoscopic surgery. Only two cases are treated minimally invasively by the laparoscopic approach. Case presentation: We introduce a 65-year-old man who had a laparoscopic sigmoid colon resection and had a lump found at the 12 mm trocar site in the right iliac area in the late postoperative phase. There were no complaints from the patient. A vermiform appendix was unexpectedly discovered in the sac of that incisional hernia during control CT scans performed by chemotherapists. Laparoscopic hernia repair without appendectomy was performed. Postoperative outcomes were excellent. Conclusions: Because of low incidence and a lack of distinctive clinical presentation of appendicitis within incisional hernia, there is a risk of delayed perioperative diagnosis and treatment. A CT scan might play an important role in verifying the diagnosis early. For better postoperative outcomes, if possible, laparoscopic surgery should be chosen.

Comprehensive testing of colorectal anastomosis: results of prospective observational cohort study.

BACKGROUND: Anastomotic leakage remains one of the most threatening complications in colorectal surgery. Intraoperative testing of anastomosis may reduce the postoperative anastomotic leakage rates. This study aimed to investigate a novel comprehensive intraoperative colorectal anastomosis testing technique to detect the failure of the anastomosis construction and to reduce the risk of postoperative leak. METHODS: This multi-centre prospective cohort pilot study included 60 patients who underwent colorectal resection with an anastomosis at or below 15 cm from the anal verge. Comprehensive trimodal testing consisted of indocyanine green fluorescence angiography, tension testing, air-leak, and methylene blue leak tests to evaluate the perfusion, tension, and mechanical integrity of the anastomosis. RESULTS: Ten (16.7%) patients developed an anastomotic leakage. Trimodal test was positive in 16 (26.6%) patients and the operative plan was changed for all of them. Diverting ileostomy was performed in 14 (87.5%) patients. However, two (12.5%) patients still developed clinically significant anastomotic leakage (Grade B). Forty-four (73.4%) patients had a negative trimodal test, preventive ileostomy was performed in 19 (43.2%), and five (11.4%) patients had clinically significant anastomotic leakage (Grade B and C). CONCLUSION: Trimodal testing identifies anastomoses with initial technical failure where reinforcement of anastomosis or diversion can lead to an acceptable rate of anastomotic leakage. Identification of well-performed anastomosis could allow a reduction of ileostomy rate by two-fold. However, anastomotic leakage rate remains high in technically well-performed anastomoses.

Tissue Coagulation in Laser Hemorrhoidoplasty - An Experimental Study.

BACKGROUND: Laser hemorrhoidoplasty (LHP) is a new technique for treatment of hemorrhoids. The exact extent of coagulation is not visible at the time of the procedure. There currently is no experimental or clinical data on the subject. OBJECTIVE: To evaluate the length of coagulation defect according to power and activation time of 1470nm diode laser on the perianal tissue model. METHODS: Fresh anorectal tissue of twenty-four pigs was used to produce 54 experimental samples. Each sample was randomly assigned to the laser power of 6, 8 and 10 W and 1, 2 or 3-second pulses. The procedure was performed using Biolitec Ceralas © diode laser with 1.85 mm optical fiber. The fiber was inserted in a manner, similar to intrahemorrhoidal laser application. Samples were evaluated using low-power and high-power light microscopy by a single pathologist. The length of tissue injury was measured on high-magnification microscopy. RESULTS: The longest tissue injury (mean 3.93 mm) was caused by the longest laser exposure time (3 sec) with no significant difference between laser power used. CONCLUSIONS: 8 W 3-second application of the 1470nm diode laser results in coagulation area approximately 4 mm, and further coagulation should be initiated approximately 5 mm from the first one.

Results of the double-blind randomized controlled trial comparing laser hemorrhoidoplasty with sutured mucopexy and excisional hemorrhoidectomy.

PURPOSE: To compare the results of laser hemorrhoidoplasty (LHP), excisional hemorrhoidectomy (EH), and sutured mucopexy (MP). METHODS: A randomized, parallel-group, double-blinded, single-center prospective study. PATIENTS: Symptomatic 2nd- or 3rd-degree hemorrhoids patients. INTERVENTIONS: Computer randomization sequence, patient blinding, operating surgeon blinding, and surgeon-evaluator blinding. LHP was performed using a 1470 nm diode laser. Up to 250 J of energy delivered per 1 hemorrhoid. The procedure was performed circumferentially. MP ligations were placed in the area of visible hemorrhoidal tissue. Standard EH was performed up to the level of the hemorrhoidal pedicle. Follow-up at 1 and 6 weeks and 1 year. OUTCOME MEASURES: Recurrence of symptoms requiring treatment, intensity, and duration of pain after the operation, patients' quality of life, fecal incontinence, and patients' evaluation of treatment. RESULTS: A total of 121 patients. Groups were even preoperatively. LHP took 15 min (SD 5.6), MP took 16 min (SD 5.58), and EH took 29 min (SD 10.3). Recurrence requiring treatment rate was 0% after EH, 10% after LHP, and 22% after MP, p = 0.004. LHP and MP were less painful than EH, p < 0.001. Patients after LHP returned to regular activity after 15 days, after MP after 22 days, and after EH after 30 days, p < 0.001. SF-36 scores were better after EH. Symptoms of fecal incontinence improved in all the groups. Patients evaluate LHP better than EH and MP. LIMITATIONS: Single-center study. CONCLUSIONS: Laser hemorrhoidoplasty is a safe, minimally invasive option for hemorrhoids, more effective than MP and less effective than EH. Patients evaluate this technique better than the other two.

Enterogenous cyst of the small bowel mesentery: a case report and review of the literature.

INTRODUCTION: Enterogenous cysts are a very rare congenital abnormality that can be found anywhere within the gastrointestinal tract, most commonly in the small intestine. The incidence is approximately one in 4500-10,000 live births. Diagnosis can be suggested by ultrasound (US), computed tomography (CT) scans or magnetic resonance imaging (MRI) findings, although histological examination confirms the definitive diagnosis. PATIENTS: We present a case of enterogenous cyst in an adult female who underwent a resection of the tumour. RESULTS: After two years of observation, there is no evidence of tumour recurrence.

Does a retrorectal tumour remain a challenge for surgeons?

Background: Retrorectal tumours are lesions with a wide range of histological differentiation that are often diagnostic and clinical challenges due to their rare occurrence. Many cases of this pathology are treated in regional hospitals, which results in serious complications because physicians fail to recognize this pathology. We present our experience in treating these tumours. Methods: A retrospective analysis of a prospectively maintained database was performed using the Vilnius University Hospital Santaros Clinics patient database. Thirty-five cases were identified. Results: Occurrence of retrorectal tumours was higher in women than in men and accounted for 82.86% and 17.14%, respectively. Computer tomography and magnetic resonance imaging were the main methods used to confirm diagnosis and plan surgical treatment. We have used a laparotomy, perineal or combined approach for tumour extirpation. The laparotomy approach was the most used, followed by perineal extirpation. The most common histological type was cystic hamartoma, accounting for 20% of cases. In 80% of cases, the histological findings greatly varied. Hospital stays varied from 3 to 21 days with a mean of 11.6 ± 5.83 days. The postoperative complication rate was 17.14% and was present in six cases. Overall survival was 85.17%, with an average follow-up period of 71.83 months. There were no recurrent tumours diagnosed during follow-up. Conclusion: Retrorectal tumours are a very rare pathology with high histological heterogeneity and problematic diagnostics. Patients should be referred to a tertiary centre that has experience and diagnostic capabilities for the best diagnostic and treatment options.

Case report: Laparoscopic approach in the treatment of presacral lipoma.

Retrorectal lipoma, as well as other retrorectal tumours, is a relatively rare disorder. Retrorectal tumours accounted for 1 in 40,000 hospital admissions. We present a case of retrorectal lipoma, 15 cm × 10 cm × 8 cm in size, treated by the laparoscopic approach. The preoperative magnetic resonance imaging visualised a mass, 12 cm × 6.7 cm × 8.6 cm in diameter, in the retrorectal space, spreading toward the left obturator foramen. Surgery was indicated due to exclude malignant process certainly, because it is difficult to differentiate lipoma from low-grade liposarcoma on non invasive imaging. Laparoscopic extirpation of the tumour was performed. The overall operative time was 80 min. The diagnosis of lipoma was established on histological examination. The patient was discharged from hospital on the 2nd day after the surgery. We have found this minimally invasive operation to be an effective and well-tolerated treatment option, determined by the experience of the surgeon.

Plastic Treatment for Giant Pseudocyst after Incisional Hernia Mesh Repair: A Case Report and Comprehensive Literature Review.

Giant pseudocyst is a very rare complication after incisional hernia repair with mesh. We present a case of 54-year-old male patient with a giant pseudocyst, which developed after incisional hernia repair with mesh. A patient was discussed during multidisciplinary team meeting and operative treatment was suggested to the patient. Extirpation of the cyst was accomplished. There was observed no defect in the abdominal wall. The patient was discharged on the 7th postoperative day. Ultrasonography two weeks after discharge again showed fluid collection. There were 6 aspirations every week starting from 400 ml serous fluid at the beginning and 60 ml at the end. There were no signs of fluid collection one month after the last aspiration. Surgical plastic treatment of giant pseudocyst after incisional hernia mesh repair is safe and feasible despite its low prevalence.

Lynch syndrome and sextuple primary malignancies.

Lynch syndrome or hereditary nonpolyposis colorectal cancer is the most common of hereditary colorectal cancer and accounts for 1-3%. Lynch and Chapelle estimated that it accounts 5-8% for all colorectal cancers. It is an autosomal dominant syndrome characterized by predisposition of various cancers (colorectal, stomach, endometrial, ovarian, renal, small bowel, and hepatobiliary tract) at earlier age than in general population and occurs as a result of mutation in DNA mismatch repair genes. This article presents a rare clinical of a 61-year-old female diagnosed with extracolonic Lynch syndrome with six metachronous tumours acquiring in digestive tract during the period from 1993 to 2014 (over 21 years). No other cases of six primary malignancies in patient with Lynch syndrome have been reported in literature. Upon diagnosis of Lynch syndrome, it is important to screen patient for malignancies of different localization as this syndrome predisposes appearance of various cancers at earlier age than in general population.

Is acute appendicitis still misdiagnosed?

OBJECTIVE: The optimal diagnostics and treatment of acute appendicitis continues to be a challenge. A false positive diagnosis of appendicitis may lead to an unnecessary operation, which has been appropriately termed negative appendectomy. The aim of our study was to identify the effectiveness of preoperative investigations in preventing negative appendectomy. METHODS: A retrospective study was performed on adult patients who underwent operation for suspected acute appendicitis from 2008 to 2013 at Vilnius University Hospital Santariskiu Klinikos. Patients were divided into two groups: group A underwent an operation, where appendix was found to be normal (non-inflamed); group B underwent an appendectomy for inflamed appendix. Groups were compared for preoperative data, investigations, treatment results and pathology findings. RESULTS: 554 patients were included in the study. Preoperative laboratory tests results of hemoglobin, hematocrit concentrations and white blood cell count were significantly higher in group B (p<0.001). Ultrasonography was performed for 78 % of patients in group A and 74 % in group B and did not provide any statistically significant results. Comparing Alvarado score results, there were more patients with Alvarado score less than 7 in group A than in group B. In our large series we could find only four independent risk factors, and they could only account for 24 % of cases. CONCLUSIONS: In summary, acute appendicitis is still often misdiagnosed and the ratio of negative appendectomies remains rather high. Additional investigations such as observation and computed tomography should be used to prevent this.

Asymptomatic heterotopic pancreas in Meckel's diverticulum: a case report and review of the literature.

INTRODUCTION: Heterotopic pancreas is defined as pancreatic tissue without a real anatomical or vascular connection to the pancreas. It can be found in the stomach, duodenum, jejunum, ileum, Meckel's diverticulum, colon gall bladder, umbilicus, fallopian tube, mediastinum, spleen and liver. Complications of heterotopic pancreas are inflammation, bleeding, obstruction, malignant transformation, carcinoid syndrome, jejunojejunal intussusception and ileus, but it is usually asymptomatic and diagnosed only during examinations for other diseases. CASE PRESENTATION: An 81-year-old Lithuanian woman was diagnosed with caecal cancer and had undergone elective surgery. A right hemicolectomy was performed and a Meckel's diverticulum was observed and excised. Histological results showed a poorly differentiated G3 adenocarcinoma of her large intestine and heterotopic pancreas tissue in the Meckel's diverticulum and mesenteric adipose tissue. CONCLUSIONS: Asymptomatic heterotopic pancreas is rarely diagnosed, and usually found incidentally during surgical or diagnostic interventions. Although it has no symptoms, heterotopic pancreas found during surgical procedures should be excised.
